Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a terminal repeater, and more particularly to a terminal repeater to which a wide mark sheet (including film-shaped or plate-shaped one) can be attached.

[0002]

2. Description of the Related Art Conventionally, in a switchboard or the like, a terminal repeater has been used for connecting internal wiring and external wiring. In such a terminal repeater, in order to identify the wiring to be connected, a mark sheet that describes the wire number of each terminal is detachably attached to the upper surface thereof. For example, in the conventional terminal repeater 1 shown in FIG. 9, when a plurality of terminal blocks 2, 2, ... Are arranged in a line, the intermediate partition wall 3 is continuous. Therefore, the mark sheet 4 is installed thereon. The mark sheet 4 is held by a pair of hook-shaped locking projections 6 formed on the upper end of the thinner side wall 5 so as to face each other.

However, since the width B of the mark sheet 4 is matched with the width of the partition wall 3, the size is as narrow as about 9 mm, and it is possible to handle handwritten wiring symbols 7, etc., but wiring symbols printed out by a word processor, etc. Space is small to use. Therefore, recently, to increase the width of the mark sheet and alternately expose the terminal screws,
A terminal repeater in which a mark sheet is slidably attached in the width direction has been proposed.

FIG. 10 shows an example of a terminal repeater 9 provided with such a slide type mark sheet. In this product, the upper surface of each terminal block 10 is made flat, and a pair of end plates 11 are provided with guide grooves 13 for slidably guiding the ends of the mark sheet 12 in the width direction (arrow X direction). The outer opening of the guide groove 13 is closed by a thin wall 14. Further, in order to prevent the mark sheet 12 from coming off from the end plate 11, an intermediate plate 16 having a guide through hole 15 obtained by crushing the thin wall 14 is interposed in the intermediate portion of the row of terminal blocks.

As the mark sheet 12, a two-fold synthetic resin sheet (or holder) sandwiching a sheet of paper on which a symbol or the like is inserted is adopted, and its width B is such that when the mark sheet 12 is at one slide end, the other is The size is such that the terminal screws 17 in the row of can be exposed. Further, at the center of the inner surface on the upper side of each guide groove 13, a protrusion 18 is provided for imparting frictional resistance to the mark sheet 12 so as to maintain the state even when the mark sheet 12 is moved in any width direction. Therefore, even when the terminal repeater 9 is mounted on the vertical wall surface in the switchboard, the mark sheet 12 does not slide down.

In such a slide type terminal repeater 9, first, as shown in FIG. 11A, the mark sheet 12 is brought closer to the slide end on the external wiring side to expose the terminal screw 17 on the internal wiring side of the terminal block. And connect the internal wiring to the terminal. At that time, the vicinity 19 of one side edge of the mark sheet 12 is pressed by the protrusion 18. Then, as shown in FIG. 11B, the mark sheet 12 is brought close to the slide end on the internal wiring side to connect the external wiring. At this time, the vicinity 19a of the other side edge of the mark sheet 12 is pressed by the protrusion 18.

As described above, in the terminal repeater 9 provided with the slide type mark sheet, the mark sheet 12 can be slid to one side to expose the terminal screw 17.
A mark sheet having a width much wider than that of the fixed mark sheet in FIG. 9 can be used, and a large space for describing a symbol for identifying each terminal can be taken.

[0008]

However, in the conventional slide type terminal repeater as described above, since the projection 18 constantly presses the mark sheet 12, the sliding operation is heavy and not smooth. In particular, if one slides with one finger, only one end side of the mark sheet 12 slides first and the whole is inclined. Therefore, a protrusion 18 is also provided on the intermediate plate 16 to give resistance at an intermediate position, but this is not sufficient. Therefore, when the mark sheet 12 is moved, it is necessary to press the vicinity of both ends of the mark sheet 12 with two fingers and perform the slide operation while keeping the parallel state, which is very troublesome. Further, when the mark sheet is attached to or removed from the terminal repeater 9, it is necessary to disassemble the terminal repeater once, which is extremely complicated. Further, for a terminal repeater of a type having a projection on the surface such as the conventional terminal repeater 1 provided with the locking projections 6 shown in FIG. Formula mark sheets are not applicable.

The present invention improves the mark sheet holding structure in such conventional terminal repeaters 1 and 9 so that the mark sheet can be easily moved, and the mark sheet can be sufficiently held at a necessary position. An object is to provide a terminal repeater with a mark sheet that does not require an intermediate plate. Further, it is an object of the present invention to provide a mark sheet moving type terminal repeater which can be applied even when a terminal block having a protrusion at the center of the upper part is used.

First, the entire terminal repeater will be described with reference to FIGS. The terminal repeater 20 is mounted by mounting a plurality of terminal blocks 22 on a mounting bracket 21 in order,
An end plate 23 is attached to each end of the row of the terminal block 22, and a fixing metal fitting 24 is attached to the outside thereof. The intermediate plate (16 in FIG. 10) used in the conventional terminal repeater (FIG. 10) is not provided. A mark sheet 25 having the form shown in FIG. 1 and a holder 26 holding the mark sheet 25 are attached to the upper surface of the row of the terminal blocks 22 so as to be movable in the width direction.

In this embodiment, except for the end plate 23 and the holder 26, they are basically conventionally known (see the terminal repeater shown in FIG. 9). That is, the mounting bracket 21 is shown in FIG.
As shown in FIG. 4, the metal is an extrusion-molded product having a U-shaped cross section and having an outwardly facing engaging piece 27. The bottom 28 has a large number of holes for attachment to a switchboard or the like. . Further, as shown in FIG. 4B, the fixing fitting 24 includes a main body 30 having a hooking claw 29 slidably engaged with the lower surface of the engaging piece 27 of the mounting fitting 21, and a holding member 32 fastened to the main body with a screw 31. The leg portion 33 of the pressing member 32 presses the upper surface of the engagement piece 27 by tightening the screw 31, and the engagement piece 27 is sandwiched together with the hook claw 29.

As shown in FIG. 4A, each terminal block 22 comprises a main body 40 made of synthetic resin, and a terminal connecting plate 41 attached to the main body, a holding metal fitting 42, and accessory parts such as terminal screws 43 for tightening. It is configured. The main body 4
0 is the bottom portion 28 of the mounting bracket 21 of various standards at the bottom thereof.
And legs 44, 45 capable of sliding engagement with the engagement piece 27.
And a thin side wall 4 for ensuring insulation between the adjacent terminal block
6 and a central partition wall 4 that maintains the distance between the adjacent terminal blocks.
7 (see FIG. 1). The terminal connection plate 41 extends through the partition wall 47. Further, as shown in detail in FIG. 1A, a shallow groove 48 into which a conventional narrow mark sheet (reference numeral 4 in FIG. 9) is inserted and a pair of locking protrusions 49 and 49 for holding the mark sheet are formed at the upper end of the side wall 46. Is provided. Inside the locking projection 49, claw portions 50 facing each other so as to engage with the upper surface of the mark sheet are provided and formed into a hook shape, and the back surface 51 is formed into an inclined surface. Note that a conventionally used cover (see FIG.
Although a hook portion 53 for locking 52) of A is provided, this hook portion 53 is not used in this embodiment. In addition, a pin 54 and an insertion hole 55 for alignment with an adjacent terminal block are provided on the upper front surface and the upper rear surface of the main body 40, and a protrusion 56 and a groove 57 for alignment are also provided on the lower portion of the main body 40. Are provided respectively (see FIG. 3).

The end plate 23 is a synthetic resin molded product having the same front shape as the main body 40 of the terminal block, and has, for example, a leg portion (not shown) similar to the terminal block at its lower part. . Then, as shown in FIGS. 1A and 1B, in the center of the upper surface, a shallow groove 58 and a locking projection 5 having the same shape as the shallow groove 48 and the locking projection 49 of the terminal block are formed.
9 are provided respectively. The locking projection 59 is relatively thick. Further, a pair of hook-shaped elastic pieces 60 are projected from both ends of the upper surface so that their tips face each other. The vicinity of the tip 61 of the elastic piece 60 is thickened in the vertical direction to some extent, and behind it, that is, on the inner surface of the root portion 62, there are recesses 65 or 64 for holding the upper and lower projections 63, 64 of the holder 26 described later. A step is formed.

A gap N having a size through which the holder 26 passes is provided between the tips of the pair of elastic pieces 60. The size may be such that the holder 26 can be inserted while bending the elastic piece 60. On the shoulder of the elastic piece 60, a hook 67 for attaching a cover, which has the same shape as that of the terminal block 22, is formed. That is, in this embodiment, the cover (reference numeral 52 in FIG. 4A) which has been conventionally used can be used as it is. Further, a thin end wall 66 for restraining the movement of the holder 26 in the length direction (arrow Y) is provided on the outer end surface of the end plate 23. In this embodiment, the end wall 66 has a chevron shape, but this is for removing the mold for the elastic piece, and there is no particular limitation as long as it can prevent the holder 26 from coming off in the longitudinal direction.

The holder 26 is a transparent synthetic resin molded product, and is usually a product having the same cross-sectional shape and extending long, for example, an extrusion molded product. The holder 26 includes a flat central plate portion 71, an upper protrusion 63 protruding upward from both side edges thereof, and a lower protrusion 64 protruding downward.
Therefore, it is substantially formed in an H-shaped cross section. Further, engaging portions 72, 73 projecting outward and engaging portions 74, 75 projecting inward are formed at the free ends of the protrusions 63, 64, respectively. The width W of the holder 26 is shown in FIG.
As shown in B, the distance L between the locking projection 59 on the left side of the drawing and the inner surface of the root portion 62 of the elastic piece 60 in the drawing is matched. Therefore, the holder 26
When one is moved to one side, the terminal screw 43 on the opposite side outside the locking projection 59 can be exposed. Further, the length of the holder 26 is set such that both ends of the holder 26 rest on the end plates 23, and in particular, the holder 26 is housed between a pair of opposed end walls 66, as shown in FIG.

The mark sheet 25 is an opaque synthetic resin sheet having a width B2 dimensioned to be inserted between the upper protrusions 63, 63 or the lower protrusions 64, 64 of the holder 26. Further, the mark sheet 25 may be any one as long as a symbol such as a line number can be written on the surface thereof, and may be paper or resin film in some cases. In this embodiment, the distance between the upper protrusions and the distance between the lower protrusions are the same, so that the mark sheet 25 can be inserted not only on the upper surface side but also on the lower surface side of the central plate portion 71 of the holder 26. it can. In the former case, it is possible to write directly on the mark sheet 25 in the mounted state, and in the latter case, there is an advantage that it is less likely to get dirty.
The user can make a selection according to the place of use.

In the terminal repeater 20 constructed as described above, as shown in FIG. 5A, the holder 26 has its end portion slid into the gap between the tips of the elastic pieces 60 so that the holder 26 and the inner surface of the elastic pieces 60 can be slid. Upper surface 7 of end plate 23
It can be inserted into the space 77 surrounded by 6 and 6 (arrow K
1) and can be pulled out in the opposite direction (arrow K
2). Therefore, it is convenient when you want to revise / add information on the mark sheet. Since the holder 26 once inserted in the space 77 is surrounded in the upper, lower, left, right, front and rear, it does not fall out of the space 77 even when carrying the terminal repeater.

When the holder 26 inserted in the space 77 is moved to one side in the width direction, for example, in the direction of arrow X in FIG. 1B, the upper and lower protrusions 63 and 64 on that side are recessed at the base of the elastic piece 60. At the same time, the other side edge comes into contact with the tip of the claw portion 78 of the locking projection 59. Therefore holder 2
Since 6 has both side edges sandwiched, it is elastically held at that position. The recess 65 or the step portion inside thereof is the step portion of claim 1, and the locking projection 59 is the projection of claim 2, both of which constitute the engaging portion according to claim 1 and claim 2.

When the other side edge is further pressed in the direction of arrow Z in this state as shown in FIG. 5B, the outward engaging portion 73 of the lower protrusion 64 on that side fits inside the locking protrusion 59. , So-called snap coupling. Therefore, the state is surely maintained unless the next removing operation is performed. The downward projection 64 of the holder 26 does not abut and snap-connect only with the locking projections 59 of the end plates 23 at both ends, but the side wall 46 of the terminal block 22 between them.
Also engages with all locking projections 49 provided on the, and snaps together. Therefore, the locking projection 59 also serves as an engaging portion. That is, the end plate 23 or the terminal block 2
It suffices to have such a locking projection on either one or both of the two. In this state where the holder 26 is moved to one side, as shown in FIG. 2, the terminal screw 43 on the side opposite to the side where the holder 26 is moved is exposed, so that wiring on that side can be performed. it can.

Next, when the holder 26 is moved to the opposite side, first raise the side edge of the holder 26 (arrow Z
2) Remove the snap connection. Holder 2 as it is
6 is pulled in the direction of arrow X2 in FIG. 5C, the lower protrusion 64
Moves over the locking projection 59, and the holder 26 moves to the other side. The other locking projection 59 does not hinder its movement. In that case, initially, the rear upper protrusion 63 in the moving direction receives the resistance of the inner surface of the horizontal portion of the elastic piece 60, and then the leading side receives the resistance of the horizontal portion of the elastic piece 60 on the opposite side. However, since the flexibility of the elastic piece 60 increases toward the central portion, the resistance is extremely low in any case.
Therefore, for example, it can be moved lightly with one finger while overcoming the locking projection 59 while maintaining parallelism. If the height of the horizontal portion of the elastic piece 60 is increased to some extent, the holder 26 can be pinched with a finger and moved once the snap coupling and the elastic engagement are released. Put the holder 26 on the other side and keep it in that state,
In the case of further snap connection, the procedure is substantially the same as the above.

As described above, in the terminal repeater 20 of this embodiment, the holder 26 can be easily attached and detached, and the holder 26 can be firmly held by the moving end moved in the width direction and locked by the snap connection. There is an advantage that it can be operated very smoothly while moving.
Further, since the holder 26 is firmly held at each moving end, even if an unreasonable force is applied to the holder 26, the holder 26 does not bend and fall off the end plate 23. Therefore, the intermediate plate used in the conventional terminal repeater is unnecessary.

In the above embodiment, the outward engaging portion 73 of the upper protrusion 63 can be omitted. When the position to insert the mark sheet 25 is only on the upper surface side or the lower surface side, the inward engaging portion 7 of the upper protruding strip 63 or the lower protruding strip 64.
4, 75 can be omitted (see FIG. 6). Further, in some cases, the entire upper protrusion 63 can be omitted.
However, in the present embodiment, the holder 26 is rotationally symmetrical and mirror-symmetrical about the center of the central plate portion 71 so that it can be used with either side facing up, for convenience of manufacturing, assembling, and use. There is.

Further, in the above embodiment, the conventional terminal block 22 having the locking projections 49 for holding the narrow mark sheet is diverted, but of course such locking projections 4 are used.
It is also possible to employ a terminal block without 9. In that case, for example, as shown in FIG. 6, the upper surface 80a of the end plate 80 is made higher than the upper surface of the terminal block 22, and the shallow groove 58 is formed.
Can be engaged at the stepped portion 81. Further, by providing the side wall of the stepped portion 81 with the claw portion 82 for snap connection, a substantially flat engagement portion can be formed. This has the advantage that the holder can be slid. In addition, the locking protrusions and shallow groove 58 in the center
It is also possible to provide a structure in which the protrusions of the holder 26 are elastically engaged or snap-coupled only by the elastic piece 60 by the sandwiching action of the base of the elastic piece 60 without providing any.

Next, a reference example of the terminal repeater of the present invention will be described with reference to FIG. In this embodiment, the end plate 23 is the same as that of the previous embodiment, but the sectional shape of the holder is different. That is, the holder 83 includes the central plate portion 84 and the upper protrusions 85 protruding upward from both side edges thereof.
And an engaging portion 86 that bends inward from the upper end of the upper protrusion 85. The upper protrusions 85 and the engaging portions 86 are for holding the mark sheet 25. Further, one projection is projected as a leg portion 87 from the center of the lower surface of the central plate portion 84, and a flat engaging portion capable of engaging with the inner surface of the claw portion 78 of the locking protrusion 59 of the end plate 23 at the lower end thereof. 8
8 are provided.

In this reference example, the holder 83 can be attached to and detached from the end plate 23 in the space 77 by inserting or removing it obliquely from the gap between the tips of the elastic pieces 60, as in the above-described embodiment. By doing. Further, as shown in FIG. 6A, when the holder 83 is moved to one side, the upper protrusion 85a of one side edge is brought into contact with the root portion of the elastic piece 60 on that side and inserted into the recess 65. , The upper projection 85b of the other side edge is brought into contact with the engaging projection 89 formed on the lower surface of the tip of the elastic piece on that side, and the leg portion 8
The engaging portion 88 of No. 7 is fitted into the claw portion 78 of the locking projection 59. As a result, that state can be reliably maintained. And when moving the holder 83 to the opposite side,
Since the lower surface of the leg portion 87 slides in the shallow groove 58, the elastic piece 60
Although it resists the elastic resistance of, it can be easily moved. Then, once the upper protrusion 85 is engaged with the engaging protrusion 8
After passing under 9, you can move lightly.

Further, since the holder 83 is firmly held at each moving end, even if an unreasonable force is applied to the holder, it does not bend and fall off the end plate 23. Therefore, the intermediate plate used in the conventional terminal repeater is unnecessary.

In this case, the mark sheet 25 can be inserted only on the upper surface of the central plate portion 84. Therefore, for example, as shown in FIG. 8B, if the height of the end wall 90 is aligned with the upper surface of the central plate portion 84 of the holder 83, only the mark sheet 25 is pulled out as shown by an arrow T without removing the holder 83. It can be inserted or reversed, which is convenient for rewriting and adding symbols. In that case, the upper end of the end wall 90 preferably has a tapered surface 91. In the embodiment of FIG. 1 as well, this configuration can be adopted, and when the mark sheet 25 is inserted on the upper surface of the central plate portion 71, it can be similarly pulled out and inserted.
