Definitions

  • the invention relates to an electrical connector with two complementary contact elements housing parts, one housing part as a plug receptacle forms a plug-in channel and the other housing part is adapted as a plug with its outer contours to the plug-in channel, and with an actuating element which, when actuated via a gear toothing with a predetermined The connector moves into or out of the connector receptacle.
  • lever ratios in connectors.
  • an electrical connector housing is described in DE-U-87 14 016, in which a lever is mounted on the plug in the gap between the plug and the plug receptacle, which engages with its short lever arm via a tooth with a rack of the plug receptacle.
  • a connector known from DE-A-28 12 901 two levers are mounted on the connector receptacle, which are connected via a pinion short lever arm each engage with a rack of the connector.
  • the geometry of the lever arm means that the transmission ratio is fixed and also limited over the entire plug-in path. Due to the space required for the pivoting movement of the lever, such connectors cannot be used everywhere.
  • the aim of the present invention is to design a plug connector of the type mentioned at the outset in such a way that the two housing parts can be locked with plug-in force transmission without a pivot lever having to be used.
  • the gear ratio should be freely selectable in a wide range and, if possible, should also be adaptable to the changing force ratios in the course of the plug-in path.
  • the actuating element is a longitudinally guided slide and that a toothing is provided on the plug receptacle, the plug and the slide, the toothing being firmly connected to two of these parts in the form of a rack and is rotatably mounted on the third part in the form of a gear wheel that meshes with the two racks.
  • a freely rotatable gear wheel is provided in the invention, which forms a transmission gear with two racks that can be displaced linearly with respect to one another.
  • the actuating element no longer needs to be pivotally mounted, but can be longitudinally movable in the plug-in direction, so that adaptation to restricted space with accessibility is only possible in the plug-in direction.
  • the gearwheel can be provided on each of the three parts which can be displaced in parallel with one another, that is to say the plug receptacle, the plug and the slide.
  • the only thing that matters is to convert the longitudinal movement of the slide via the gear toothing into a longitudinal movement of the plug, the path of the slide generally being longer than the path of the plug to reduce the plug-in and pulling forces.
  • the gear is mounted on the connector so that it meshes with a rack of the connector receptacle and the slide, these two racks preferably being arranged on both sides of the gear axis.
  • a gear that meshes with the two racks and with the same tooth pitch over a single sprocket already gives a plug-in ratio of 1: 2, since the plug carrying the gear covers only half the distance as the slide provided with a rack .
  • the gear is mounted on the slide and meshes with a rack of the plug and the plug receptacle, these racks now preferably running parallel on the same side of the gear axis.
  • the racks and / or the gearwheel provided with two ring gears must have different pitches.
  • the transmission ratio can also be designed differently by changing the pitch in the course of the plug-in movement and thus be adapted to the different plug-in forces. For example, it can be provided that the transmission ratio is low as long as only the Housing parts are pushed into each other, and that it becomes larger when all contact elements are engaged with each other at the end of the plug-in movement and thereby require high plug-in forces.
  • interlocking latching elements are provided on the plug receptacle on the one hand and on the plug or the slide on the other hand, which lock the housing parts against one another at the end of the plug movement.
  • FIG. 1 shows in section a connector 1 installed on a printed circuit board 10, the three parts of which, namely a connector receptacle 2, a connector 3 and a slide 4, are completely pushed into one another. Contact elements and cable connections in the plug are not visible or not shown. Show only two circuit board pins 5 the connection of the connector 1 to the printed circuit board 10. The direction of insertion for the movement of the connector 3 and the slide 4 is indicated by the arrow 6.
  • Figure 2 shows the connector of Figure 1 in plan view and partly in section, the cut being made so that the connector 3 with the gear is not visible in this area.
  • the connection pins 5 and the printed circuit board 10 are also omitted in FIG. 2. So only openings 51 are indicated for the pins.
  • the rack 45 of the slide 4 can be seen in the interior of the plug receptacle, and the latching of the slide via a locking lug 41 in a recess 22 of the plug receptacle.
  • the slide 4 is shown in Figures 3 and 4 in two views. It can be seen that two sliders 4 are connected via a bracket 40 to form a common actuating element, each of the sliders 4 having a rack 45 on diagonally opposite regions of the plug.
  • the plug 3 also has a gear 7 on two opposite sides, and the plug receptacle 2 has a rack 25 on each of these opposite sides.
  • the slide has a locking lug 41 on each side, which, as already mentioned, latches in a recess 22 of the plug receptacle.
  • the locking lug 41 is elastically connected to the respective slide 4 via a spring arm 42, so that the lock can be released by bending the spring arm 42.
  • the design of the spring arm with the locking lug is shown in perspective in FIG. A modification is shown in FIG. 6, with the locking lug 41 being formed on the underside of the spring arm 42. In this case, a corresponding notch, not shown here, would have to be provided at a correspondingly different location on the connector receptacle.
  • FIGS. 5a to 5c The mechanism of the plug-in force transmission for the example described so far is illustrated with the aid of FIGS. 5a to 5c. From this it can be seen that the axis of the gear wheel 7 formed by the bearing pin 31 is located in the middle between the two racks 25 of the plug receptacle 45 of the slide, which are opposite one another in parallel. The gearwheel is in engagement with the outermost tooth of the rack 25 at the beginning of the insertion movement of the plug 3 into the plug-in channel 21 and on the opposite side with the innermost tooth of the rack 45; this state is shown in Figure 5a. When the slider 4 moves in the direction of the arrow 6, the gear 7 is rotated clockwise.
  • FIG. 5b shows a middle insertion position
  • FIG. 5c shows the end position in which both the plug 3 and the slide 4 are completely inserted into the plug channel 21 of the plug receptacle 2. Since the tooth pitch of the gear 7 is the same as that of the racks 25 and 45, this results in a transmission ratio of the forces of 1: 2 between the slide and the connector. At the end of the insertion movement, the slide is locked in the manner already described with the plug receptacle.
  • the gear 7 is on the slide 4, while the connector receptacle 2 has a rack 25 and the connector 3 has a rack 35.
  • the toothed racks 25 and 35 are located next to one another on the same side of the toothed wheel axis, and a toothed ring 75 or 76 of the toothed wheel is assigned to the two toothed racks.
  • Different divisions of the rack 25 meshing with the ring gear 75 on the one hand and the rack 35 meshing with the ring gear 76 on the other hand result in a desired transmission ratio in such a way that the ring gear 75 rolls on the rack 25 faster than the ring gear 76 on the rack 35.
  • the gear ratio can be chosen arbitrarily by a person skilled in the art, it being also possible to take into account whether the two toothed racks are opposed to one another or are on the same side with respect to the axis of rotation of the gearwheel by appropriately dimensioning the toothed rings of the gearwheel.
  • a change in the pitch in the course of the insertion movement could also be generated, which is not shown, in order to adapt the transmission ratio to the insertion forces which occur; because these insertion forces are greatest when the contact elements, not shown, mesh completely at the end of the insertion movement.
