Description

PLUG WITH SLIDING PLUGS AND LOCKING DEVICE DESCRIPTIVE MEMORY The invention relates to a plug with sliding pins and locking device, in accordance with the preamble of claim 1. W0-A2-02 / 063723 describes a plug with a faera housing from which several sets of pins slide, each set it is intended for a specific type of power point. The pins slide out by means of levers that extend out through separate slots in the housing. The levers and pins of a type in each case are connected to each other within the housing by a connecting part that slidably accommodates in the housing. The plug also has a safety element. Said security element accommodates to slide laterally in the housing. Laterally slidable should be understood as in a direction transversely to the sliding directions of the pins. The safety element slides by means of a push button located outside the housing. The security element comprises several holding bars. Said latch bars extend in the same direction as the pins. The retaining bars have an inclined sliding surface which is fused by means of a straight sliding surface, i.e. a surface extending in the direction of the pins, in an opening. The connecting part of the pins is provided with sliding heels. During the sliding process out of a set of pins by means of the lever, the sliding heels slide along the inclined sliding surfaces of the retaining bars. Due to the fact that the pins are fixed in the radial direction, this sliding along the inclined sliding surfaces results in the safety element sliding laterally. At the end of the retaining bars the sliding heels reach the position of the corresponding openings of the retaining bars. Under a spring force the sliding beads fall into the openings, so that the safety element slides back and the safety element is closed with the pins. A drawback of the known plug is that the plug can be less reliable in the long term as a result of wear. The projection corners of the sliding bead and the opening can be worn out and acquire, for example, a beveled and rounded profile. The result is that the locking of the sliding bead in the opening becomes less reliable and the pins can be inadvertently pushed into the housing. The invention aims to eliminate the drawback at least partially, or in any case provide a usable alternative.

In particular, the invention seeks to provide a more reliable locking system that can retain its reliability also in the long term. The invention achieves this objective by means of a plug in accordance with claim 1. The plug comprises a housing with a first contact face, a first set of pins for a first type of power point, and a first blocking device which it comprises interacting the first and second blocking means. The first set of pins slidably accommodates the housing to assume an active or passive position as desired, the first set of pins in the active position projecting from the first contact face of the housing such that said set of pins can be inserted in the first type of power point. The first blocking means is connected to the first set of pins. The second blocking means is connected to the housing. The first and second blocking means move relative to each other, so that they can assume a blocking position, wherein the slidable capacity of the first set of pins is blocked, and an unlocked position, wherein the first set of Pegs is slidable. The first locking device further comprises a first plug, the first plug of which moves between the stop position, wherein the mobility of the first and second locking means relative to one another and a release position is prevented.

The plug according to the invention provides a separate closure of the first and second locking means, with the result that less rapid wear of the first and second locking means causes the blocking to become less reliable. In particular, the first plug moves in a sliding direction of the first set of pins. By making the plug slide in the same direction as the pins, it is ensured that an effective use of the space in the plug can be achieved. In the embodiment according to the prior art, on the other hand, the safety element slides transversely to the direction of sliding of the pins, resulting in a separate space having to be reserved for this interior of the housing, at the axial end of the pins In one embodiment, the second locking means intends to interact with the first locking means to lock the sliding capacity of the first set of pins in the active position. the third locking means, which is connected to the housing, to interact with the first locking means to block the sliding ability of the first set of pins in the passive position.This way the locking in the active and passive positions is achieved by the same blocking device, so that the first blocking means fulfills a double function, in particular, the first blocking device comp a second plug is disposed, the second plug of which moves between a stop position, wherein the mobility of the first and third locking means relative to one another is prevented, and a release position. Thanks to the second plug, locking in the active and passive positions can be reliably closed. More particularly, the first and second plugs are permanently connected to each other. This makes it possible to obtain a simple control system, wherein when activating a part both the first and second plugs can move in the release position or in the stop position. In one embodiment, the plug further comprises a second set of pins for a second type of power point. In this way a so-called multiple socket is formed, the multiple plug of which can be usefully used in various types of power points. In particular, the plug further comprises a two-sided sliding element, slidably accommodated in the housing to assume a first and second position as desired. The two-sided sliding element comprises first and second pin faces. The second face of the pin is provided substantially diametrically opposite the first face of the pin. The first set of pins extends from the first pin face and the second set of pins extends from the second pin face. The first set of pins in the first position projects from the first contact face of the housing such that said set of pins can be inserted in the first type of power point. The second set of pins in the second position projects from a second contact face of the housing such that said set of pins can be inserted into the second type of power point. The use of said common sliding member results in not only a simple construction, but also a simple operation.

The blocking of the sliding element in the active position for the first set of pins corresponds to the blocking of the second set of ^ Pegs in their passive position. In a variant the second set of pins comprises at least three pins, one of which is an opener for a fused power point, such as a British power point. In addition, the first set of pins is provided in a first slide member that is provided to slide around the opener of the second set of pins. By providing the sliding element around the opener of the second set of pins is possible, if desired, supply with separate guide means for fixing the first set of pins during the sliding movement in the radial direction. It is noted that in the prior art described above, the sliding movement is only along the opener, so that in that case an additional guiding means has to be provided. A plug that slides around the opener of the second set of pins therefore offers advantages compared to the prior art which are independent of other aspects of the invention.

In particular, the first locking means is provided in the first sliding member, and the second locking means in the opener. The opener is permanently connected to the housing, and the cap is provided in the opener. By providing the second locking means in the opener and the stopper in the opener, a compact and simple construction is obtained.

Figure 1 shows a plug in accordance with a first embodiment of the invention, which is indicated in its entirety by the reference number 100. The plug 100 is intended to be used as a mains plug to provide lighting and / or household appliances with energy. The plug 100 comprises a housing 101 with a contact face 102. The housing 101 is further provided with a through connection opening 103 (Figures 2 and 3) for a power cable., and with a cover 104 for closing an opening for adjusting a fuse, as required in some countries. The cover is provided in a part of a rear wall 105. The rear wall 105 is the part of the housing 101 which is diametrically opposite to the contact face 102. The plug is provided with a first set of pins 110, the dimensions and mutual positioning of which is suitable for use in a first type of power point, in the example shown a type of power point that is generally used in the European continent. The pins 110 are slidably accommodated in a sliding housing 111. The set of pins 110 and the sliding housing 111 together form a plug of the so-called flat type. This is a plug that can be provided in appliances for which a ground connection is not required. The sliding direction of the pins 110 is also mentioned below as the axial direction, while a radial direction is transverse to the axial direction. In this first exemplary embodiment the axial direction corresponds to a direction from the rear wall 105 towards the contact face 102. In figure 1, the ends of a second set of pins 12 is also visible, the second set of pins of which will be reversed in greater detail below in relation to FIG. 13 forward. In figure 3, a first push button for the European flat plug, or Euro push button 1 13 can also be observed. A British button 114 can also be observed. With reference to Figure 4, the sliding housing 111 slidably accommodates in the housing 101. For this purpose, the sliding guide means is accommodated in the form of a sliding tube 120. The first set of pins 110 is permanently connects to a first sliding element 121, in this case a sliding element of a face, also referred to as a bridge. The sliding element of one face 121 is provided with two sliding lugs 122, which are placed diametrically opposite one another and can slide in grooves 123 of the sliding tube 120. The one-side sliding element 121 extends around the tube of sliding 120. In other words, the sliding element of a face 121 is provided with an opening corresponding to the outer part of the sliding tube 120. Due to the fact that the first sliding element 121 is of a certain thickness, the opening can be seen as a tubular opening. The slide tube 120 is provided with one or more first stops 124 (FIG. 5). The first stops 124 are bevelled on their side facing the contact face 102. The glide heel ~ fcrT22 ~ of the one-side sliding member 121 is bevelled in a complementary manner. The sliding bead 122 is also bevelled on its axially opposite side. The beveled sides or faces of the sliding bead 122 can be viewed as the first locking means 125. The sliding tube 120 is provided with the second locking means in the form of locking edges 126. The locking edges 126 move, in this example with a hinge, connected to the sliding tube 120. In this exemplary embodiment, the locking edges 126 are formed by separating the material from the sliding tube 120 along three sides of the locking edge 126. Along the fourth side of the locking edges 126, that is, the side where no material is left, the material of the sliding tube 120 acts as a hinge. By selecting slightly elastic material for the sliding tube 120, the strip of material not only connects in hinge, but is also elastic.

The blocking edge 126 is provided with a locking lug 127. The locking lug 127 is provided with beveled walls, the bevel of which corresponds to that of the bevelled sides 125 of the sliding bead 122. To complete, it is noted that in the drawing in FIG. section according to figures 4 and 5 it seems as if one end 129 of the sliding tube 120 is not connected with the main part of the sliding tube 120. This is the end 129 located on the side of the first contact face 102. It can be seen more clearly in FIGS. 9 and 13 that this is in fact a continuous sliding tube 120, wherein only the blocking edges 126 partially detach from the rest of the tube. A stop element in the form of a stop bar 130 is accommodated in the slide tube 120. A first end of the stop bar 130 acts as the push button Euro 113 here. The other end of the stop bar 130, ie the end of the stop bar 130 projecting from the contact face 102, is provided with spring means in the form of a coil spring 131. The coil spring 131 is accommodated in an opening 132 in the axial end of the stop bar 130, and projects partially from said end face 132. The coil spring 131 rests on one side in the opening and on the other side on an internal flange 133 of the end 129 of the slide tube 120. The stop bar 130 is provided with one or more plugs 135. The plugs 135 may be heels or radially projecting portions on the outer wall of the stop bar 130. In this case there may be two or more plugs 135, or there may be a plug 135 extending in the circumferential direction around the stop bar 135. It is noted that the central part of the stop bar 130 has the same external diameter as the outer diameter of the circumference around the plugs 135. This is in particular functional for the sliding arrangement of the stop bar 130 in the sliding tube 120. However, the diameter of this central part of the stop bar is not relevant for the stop function of the plugs 135 What is relevant is that the diameter of the part 136 of the stop bar 130 which in the axial direction is directly connected to the first plugs 135 has a diameter smaller than the diameter around the circumference of the plugs 135. As will arise further down, the recessed part 136 of the stop bar 130 has a function in releasing the blocking means. Figures 6-10 show the plug 100 in a position where the first set of pins 110 and the second set of pins 112 slide in the housing, but not the opener described below. Figures 9 and 10 show the interaction between the first blocking means described above 125 of the sliding element of a face 121 and the third blocking means to be described below. In Figures 9 and 10, the sliding element of one face 121, the first set of pins 110 connected thereto (not visible in its section) and the sliding housing 111 are pushed completely into the housing 101. It is pointed out that the The axial end of the sliding housing 111 is in the same plane as the contact face 102, as can be seen in figure 6. The sliding tube 120 is provided with a third locking means, in the form of blocking edges 140. The locking edges 140 are provided with locking lugs 141. The locking lugs 141 have beveled sides corresponding to the bevel of the first locking means, or the beveled faces 125 of sliding skid 122. In the space between the sliding housing 111 and the sliding tube 120 the spring means 142 are also provided, in the form of a coil spring. The coil spring 142 acts, at least in the position shown in the drawing, on the sliding element of a face 121 and on the inner part of the housing 101. In this way the coil spring 142 exerts an axial force from the wall rear 105 of housing 101 toward contact face 102. Stop bar 130 is provided with a second plug 145. Second plug 145 at the first axial end is fused in the above-described central part of stop bar 130. In its second axial end the second plug 145 is joined to a part 146 of the stop bar 130 with a reduced diameter. The locking edge 140 in this example is formed from and connected to the sliding tube 120 in a manner comparable to the first locking edge 126.

In this way, a first locking device 149 is formed, which comprises beveled faces 125, locking edges 126 and 140 with locking lugs 127 and 141 respectively, and the axial stop bar 130 with plugs 135 and 145. In use , the push button Euro 113 can be pressed in the axial direction, as shown in figures 11 and 12. The operation, that is, the pressure, of the push button Euro 113 causes the stop bar 130, and therefore also the plugs 135 and 145, moving in the axial direction axial movement of the plugs 135 and 145 means that said plugs move in the axial direction relative to the locking edges 126 and 140, thereby releasing the locking edges 126 and 140. In other words, the locking edges 126 and 140 rest on the position of the parts 136 and 146 of the locking bar 130 with reduced circumference. The first plug 135 and the second plug 145 in this manner move from a stop position to a release position. In the stop position the radial mobility of the locking edges 126 and 140 relative to the sliding bead or the first locking means 125 is avoided. In the releasing position, the locking edges 126 and 140 move in the radial direction, as shown by the arrows 150 for the second locking edges 140. Partly as a result of the beveled shape of the locking lugs 127 and 141 respectively and the bevelled sides 125 of the sliding bead 122, the sliding bead 122 can move the locking edges 126 and 140 out of the locking position (shown) in an unlocked position (not shown). In the unlocked position (not shown) the sliding edges 126 and 140 are located in the opening formed by the parts 136 and 146 of the stop bar 130 having a reduced cross section. From the position in figures 11 and 12, the coil spring 142, in the released position of the plug 145, as shown in FIG. 11, will provide the locking edges 126 and 140 for pushing in the non-locked position. From the push-out, the active position of the first set of pins 110 and the sliding housing 111, as shown in Figs. 1-4, the user himself will push the sliding element of a face 121 inwardly into the axial direction and thus push the locking edge 126 radially inward. For this purpose, the user can exert force on the first set of pins 110 and / or the sliding housing 111. Figures 13-18 show the same first embodiment of the plug 100, wherein the mode of operation of the second set of pins 1 12 is explained. The second set of pins 112 comprises two live pins 160 and one opener 162. The opener 162 is also referred to as a ground pin, but since the plug 100 in the exemplary embodiment is not shown to ground, the term opener is a description better here. For British power points a plug must in fact be present in the ground-to-ground position even in the case of ungrounded plugs in order to unlock the power point.

The opener 162 in this exemplary embodiment is equivalent to the slide tube 120, and in this mode is permanently connected to the housing 101. For the British pegs 112, and in particular the two slidable pegs 160, a second locking device 165 is provided. The plug 100 comprises a sliding guide means in the form of a sliding tube 170, which is permanently connected to the housing T01 and extends into the housing from the rear wall 105 to the contact face 102. This address will be mentioned here hereinafter as the axial direction, and also is a sliding direction for the pins 106. A stop 172 is provided within the contact face 102, which stop extends around the second slide tube 170. The pins 160 are connected to a second sliding element of a face, in this case a bridge 171. The bridge 171 is provided with an opening extending around the sliding tube 170. The thickness of the bridge 171 in the position of the opening is such that this is a material of a tubular opening in the bridge 171, whose tubular opening extends around the slide tube 170. The bridge 171, or at any proportion its tubular aperture, is provided with two beveled faces which are joined to the tubular aperture in the bridge 171. Said beveled faces 175 act as the fourth means of blocking.

The slide tube 170 is provided with a fifth locking means in the form of a third locking edge 176 with locking lugs 177. The locking lugs 177 are bevelled for interaction with the bevelled faces 175 of the bridge 171. The blocking edges 176 are formed of the slide tube 170 in a manner comparable to the locking edges described above. The inclined plane faces 175 and the third blocking edges 176 with the locking lugs 177 are part of the second locking device 165. The second locking device 165 further comprises a second stop element in the form of a second stop bar 180. The stop bar 180 is provided with a coil spring 181 at the axial end. The stop bar 180 is further provided with a third stopper 185. The third stopper 185 is formed by means of an opening, ie a part 186 of the stop bar 180 with a reduced diameter axially connecting the stopper 185. slider 170 is further provided with fourth locking edges 190, which have the fourth locking lug 191. The second stop bar 180 is provided with a fourth plug 195. The fourth plug 195 is formed by means of an opening 196 in the stop bar 180. These fourth locking edges 190 and fourth plugs 195 may also be part of the second locking device 165. In the position of use shown in Fig. 16, the plug 100 is now ready to be used in combination with a British power point. The pins 160 are blocked by the interaction of the fourth locking means 175 and the fifth locking means 176. In this case the plug 185 prevents radial mobility of the locking means 176 relative to the locking means 175. A certain locking of the pins 160 is obtained in this way. In figure 17, a user has pressed the British button 1 14 and in this way moved the stop bar 180 in the axial direction. This causes the cap 185 to move in the axial direction away from the locking edges 176, and the locking edges 176 move in the radial direction relative to the locking faces 175 of the bridge 171. When exerting pressure in the direction axially on the bridge 171, for example by means of the pins 160, the bridge 171 with the pins 160 can now slide inwardly along the slide tube 170. The locking edges 176 move radially inward in the process. After the pins 160 have slid completely and while the button 114 has been released by the user, the situation shown in FIG. 18 occurs. This is in fact the same situation as that shown in FIGS. 10, but in this case in the position of the same plane in section as in FIGS. 16 and 17. The bridge 171 is locked in this position by blocking edges 190, more particularly by the locking lugs 191 provided in the blocking edges. 190. Thanks to the plugs 195, the locking edges 190 and the locking faces 175 on the bridge 171 can not move relative to one another in this position, resulting in the pins 160 being locked in the passive position it is shown in figure 18. The release of this blocked passive position is performed in a manner corresponding to that described above in relation to the release of the active position. The figures described above e do not show that the first set of plugs 110 and the second set of plugs are electrically connected in a disconnectable manner by means of contacts to power cables running through the through connection opening of the cable 103 to the external part of the plug 100. Thanks to the contacts, only one set of pins at the same time is connected to the power cables. Figure 19 shows a plug 200 in accordance with a second embodiment of the invention. The plug 200 is intended to be used as a mains socket, for ground applications. The plug 200 comprises a housing 201 with a first contact face 202. The housing 201 is further provided with a through connection opening 203 for a power cable and a cover 204 for a fuse. The housing 201 further comprises a second contact face 205, which is provided substantially diametrically opposite the first contact face 202. The shape and dimensions of the first contact face 202 correspond to those of a power point placed to ground of a first type, in this case of the type generally found in the European continent. The shape and dimensions of the second contact face 205 correspond to those of the power points of a second, type in this case, for example, of the type generally found in the British Isles.

The plug 200 is provided with a first set of pins 210 (Fig. 26), which is suitable for use in the first type of power point. The first set of pins 210 is provided in a sliding member 211, in this case a two-sided sliding member 211. The sliding member 211 is slidably accommodated in the housing 201, so that it can optionally assume a first position (figure 22) and a second position (figure 26). The plug further comprises a second set of pins 212 (Figure 19-24), suitable for the second type of power point, and a push button 213. The push button 213 is recessed in the second contact face 205. The sliding member 211 it comprises a first pin face 215. The first set of pins 210 extends from the first pin face 215, in this case perpendicularly to the pin face 215.

For this purpose, the first set of pins 210 is permanently connected to the slide member 211. The slide member 211 further comprises a second plug face 216, from which the second set of pins 212 extends. The second set of pins 212 is located to be perpendicular to the second pin face 216 and is permanently connected to the two-sided sliding member 211. The first pin face 215 and the second pin face 216 of the sliding member 211 are they provide diametrically opposed to each other in the sliding element 211.

With reference to Figures 22-21, the two-sided sliding member 211 is slidably accommodated in the housing 201. For this purpose, sliding guide means in the form of a sliding tube 220 are provided. The sliding member two-sided 211 is provided with two sliding lugs 222, which are placed diametrically opposite each other and can slide in grooves 223 of the tube sliding tube 220. The sliding tube 220 extends from the first contact face 202 to the second contact face 205. For what is presented below, the axial direction is defined as the sliding direction of the two-sided sliding element 211, which in this case is determined by the longitudinal direction of the sliding tube 220. Two-sided sliding element 211 extends around the sliding tube 220. For this purpose, the two-sided sliding element 211 is p It is provided with an opening, in particular a tubular opening, the dimensions of which correspond substantially to the outer part of the sliding tube 220. The sliding heels 222 are bevelled on two diametrically opposed sides to form a fourth locking means, or faces Lock 225. It is noted that the locking faces 225 are located at the axial ends of the sliding beads 222. The sliding tube 220 is provided with a fifth and sixth locking means, in the form of first and second blocking balls 226 and 227. The first and second locking balls 226 and 227 are movably connected to the sliding tube 220 such that they move in the radial direction relative to the sliding tube 220, and are fixed, ie, not move, in the axial direction of the sliding tube 220. The sliding tube 220 is accommodated with a first end 229 in the part of the housing 201 that forms the first ca contact element 202. A stop element in the form of a stop bar 230 is accommodated in the slide tube 220. A first end of the stop bar 230 acts as the push button 213 in the present. At the other end of the stop bar 230 the spring means is provided in the form of a coil spring 231. The coil spring 231 rests on one side of the axial end face 232 of the stop bar 230 and rests on the other side on the inner rim 233 of the end 229 of the slide tube 220. The stop rod 230 is provided with a first stopper in the form of a stop ring 235. The stop ring 235 is joined at its first axial end by the end face 232. At its second axial end the stop ring 235 is joined by a part of the stop bar 230 with a cross section reduced to 236. Due to the fact that the rest of the stop bar 230, notably the central part of the stop bar 230, has an external diameter corresponding to the external diameter of the stop ring 235, the part 236 with a reduced cross section can also be a circular opening or slot 236.

The stop bar 230 is further provided with a second plug 245. The second plug 245 can be a second stop ring 245, which extends around the external surface of the stop bar 230. The second stop ring 245 in the axial end is fused in the central part of the stop bar 230. Due to the fact that the stop ring 245 and the central part of the stop bar 230 have the same external diameter, the second stop ring 245 in this case it fuses homogeneously in the remainder of the stop bar 230. In the second axial end, the second stop ring 245 is joined by a part 246 of the stop bar 230 with a reduced diameter. The part 246 with reduced diameter can also be a circular opening or slot 246 on the surface of the stop bar 230. The locking faces 245 of the sliding bead 222, the first locking ball 226 and the second locking ball 227 and the first stop ring 235 and the second stop ring 245 are part of the locking device 249. In the position in use of Fig. 22, in other words the position where the socket 200 is suitable for power points of the British type , the second set of pins 212 is blocked in a certain way. The locking faces 225 rest on the locking ball 227, which in turn can transmit an axial force to the sliding tube 220, and therefore to the housing 201. The locking ball 227 is locked in the locked position of use. , or it is stopped by the second stop ring 245. The blocking ball 227 as a consequence can not move in the radial direction.

Upon pressing the push-button 213 against the spring force of the coil spring 232, the second stop ring 245 moves away from the second locking ball 227. The fact that the first stop ring 235 and the second stop ring 245 connected to each other by means of the stop bar 32 means that at the same time the first stop ring 235 moves away from the first blocking ball 227. However, this is not important in the position shown in figures 22 and 23. The axial movement away from the second stop ring ~ 24"5 so that the second circular opening 246 of the stop bar 230 reaches the position of the second locking ball 227 (FIGS. 24, 25). in the axial direction in the two-sided sliding member 211, for example by means of the second set of pins 212, will cause the locking face in inclined plane 225 to push the second locking ball 227 into the second circular opening 246. This results in the situation shown in Fig. 25. In this release position of the second stop ring 245 the locking action of the locking faces 225 and the locking ball 227 is removed. The situation shown in FIGS. 26 and 27 is then produced by pushing the slide member 211 further and releasing the push-button 213. The two-sided slide member 211, and consequently the first set of pins 210, now lock into the axial direction by means of the locking face 225 of the sliding bead 222 and the first locking ball 226, which itself rests on the slide tube 220. The first locking ball 226 does not move in the radial direction, in the presence of the first stop ring 235. If the push button 213 is pressed again, in the situation of figure 27 a situation will arise broadly corresponding to that of figure 25. The first circular opening 236 will go to the position of the first locking ball 226, grasping the latter moving in the radial direction, so as to remove the locking effect between the first locking ball 226 and the locking face 225. Figures 28-3 1 show a plug 300 in accordance with a third embodiment of the invention. The plug 300 is intended to be used as a mains plug, for ground applications.

The sliding member 311 and the housing 301 are provided with locking means (not shown). In addition, the plug 301 is provided with a stop bar (not shown), one end of which acts as the push button 313. The design and operation of the locking means and the stop bar can be comparable with those of the second. modality, as shown in figures 22-27. However, it is noted that instead of blocking balls, as shown by reference numbers 226 and 227 of Figures 22-127, it is also possible to use blocking edges, as shown and described in relation to the first embodiment, or a differently designed stopper that moves between a stop position where mutual mobility of the blocking means is prevented, and a release position. Figures 32-35 show a plug 400 in accordance with a fourth embodiment of the invention. The plug 400 is intended to be used as a mains plug, for applications not connected to ground. The plug 40 comprises a housing 401 with a first contact face 402. The housing 401 is further provided with a power cable 403. The housing 401 further comprises a second contact face 405, which is provided substantially diametrically opposite the first face 402. The shape and dimensions of the first contact face 402 correspond to that of the ungrounded power point of a first type, in this case of the type generally found in the European continent. The shape and dimensions of the second contact face 405 correspond to those of the power points of a second type, in that case of the type generally found, for example, in the British Isles, including Ireland and Hong Kong. The plug 400 is provided with a first set of pins 410 (figure 33), which are suitable for use in the first type of power point. The first set of pins 410 is provided in a two-sided sliding member (not shown). The sliding element is slidably accommodated in the housing 401, so that it can assume a first position (figure 32 and 33) and a second position (figures 34 and 35) as desired.

The plug further comprises a second set of pins 412 (FIG. 34) and a push button 413. The push button 413 is recessed in the first contact face 402. The second set of pins 412 comprises two live pins 460 and an opener 462. Since plug 400 in the exemplary embodiment shown is provided for power points not connected to ground, opener 462 serves to unlock the intended power point. The first set of pins 410 and 4 live pins 460 of the second set of pins 402 extend from the respective pin faces (not shown) of the sliding element. The opener 462 in this exemplary embodiment is connected to the housing 401 in such a manner that it rotates about an axis of rotation (not shown). Otherwise, in a variant of this fourth embodiment the opener 462 can also be connected to the sliding element, as shown in the second and third embodiments, or can be permanently connected to housing 401 in order to act as a sliding element, as shown in the first embodiment. The locking means and a plug are accommodated in the housing 401, which plug is connected to the push button 413. The locking means and plug are designed in a manner comparable to that shown in detail with respect to the first and / or second modality. The electronic equipment is also accommodated in the housing 401 of the plug 400, for transforming and / or rectifying an electric current that is introduced into the housing 402 by means of the first set of pins 410 or the second set of pins 412. The electronic equipment may further comprising a control system for switching and / or measuring a desired amount of current, for example with a view for charging an electrical consumption device having a battery. Examples of such appliances for electrical consumption are mobile phones, shavers, laptops (portable or other), navigation systems, portable audio equipment, video cameras, fixed cameras and electrical equipment. Electronic equipment may also be suitable for direct charging of a set of interchangeable rechargeable batteries. The fastener for accommodating the rechargeable batteries can be integral with the housing 401 of the plug 400, or it can be connected to said housing by means of the power cable 403. In the case of direct charging of electrical appliances, the power cable 403 It will usually end in a female type plug, which can be connected to the intended electrical appliance. Depending on the intended application, electronic equipment does not necessarily have to include a control system to measure the load current. It is also not necessary in all cases to rectify the transformed current. Within the scope of the invention, a number of variants are possible for the parts shown. For example, a plug with only one set of pins, is possible, for a simple plug whose pins are telescopic. It is also possible that the plug is provided with more than two sets of pins. In addition, types of plugs other than mains plugs may be provided with plugs with a locking device in accordance with the invention. Although the illustrated embodiments are in the form of a plug with a power cable, it is also possible to design the invention in the form of a displacement adapter or plug. In that case one face of the housing is provided with plug receiving means, or a power point for one or more types of plugs. Of course, electronic equipment for transforming and / or rectifying the current, as described herein in relation to the fourth embodiment, may also be present in different sockets designed in accordance with the invention. Other combinations of pins, and plugs that are suitable for countries other than those described, are also possible. Other blocking means are conceived in addition to the blocking means shown, in the form of beveled faces, blocking edges and locking bullets. It is also pointed out herein that beveled faces are bevelled to facilitate movement of the locking means away from each other when the plug is in the release position. However, it is also conceived that the locking means in the released position move away from each other in other ways, for example, by means of a spring means. In that case, the locking faces do not need beveling, and may extend, for example, substantially in a radial direction.

The plugs shown are largely integral with the stop bar where they are provided. However, a plug can also be provided in the form of, for example, a separate ring, or the separate beads, provided in a stop element. If several plugs are provided in a locking device, as illustrated, they do not need to be provided in the same stop element and thus may be operable by means of a stop and pusher element. The plugs are also "plugged" into individual elements and operated individually if desired.One or more sets of pins can be movably connected to the housing in a different way from those which are slidably connected. The set of pins rotates rotatably outside the housing The invention in this way provides a plug with a set of sliding pins and a locking device The locking device comprises a plug which ensures greater reliability and is not susceptible to wear. The plug can also be produced in a simple manner, with a relatively small number of parts.The necessary parts for the locking device occupy very little space in the housing, due to the fact that they extend partly in the direction of sliding of the pins The locking of the pins that are pushed out in the active position and the pins that are in the housing it can be carried out partly by means of the same locking device. This means that fewer different parts are required than in the case of the prior art.
