Definitions

  • the invention relates to an electrical connection device for motor vehicles according to the preamble of claim 1 and contact elements for use in such connection devices.
  • These connectors are mainly used to connect a trailer to a towing vehicle.
  • leads crimping are known in which a metal strip crimped by means of a special pliers and crimped to the lead wire or, if the lead wire is formed as a strand is pressed into the strand.
  • Such compounds have the disadvantage that they can not be solved easily, so that after the separation of a completely new connection must be made, the lead wire is necessarily shortened, which can lead to problems.
  • Other solutions provide that the connecting wire is curved in the manner of an eyelet and clamped in a corresponding holder with a clamping screw.
  • the contact element has a sleeve or a bore into which the lead wire to be fastened is inserted and retained therein with a screw extending transversely to the direction of insertion through the wall of the sleeve or bore.
  • Such screw have the advantage that they are solvable, however, the work required to connect and disconnect is quite high.
  • the screw usually consist of iron and can therefore rust, which makes it much more difficult to loosen the clamp connection.
  • the object of the invention is therefore to modify the known electrical connection devices so and further develop that a fast, but secure fastening of the leads is possible.
  • connection parts of the connecting devices are provided with a clamping spring, said clamping spring presses the connecting wire to a contact surface of the contact element.
  • the spring connection needs to be bent only briefly, that the wire can be inserted; if the spring is relieved, the lead wire is clamped and held on the contact surface due to the spring preload.
  • the opening of the clamping spring can be done by appropriate action on the connecting wire or with an auxiliary tool.
  • Figure 1 shows an exploded view of a, the towing vehicle specific box of a connector according to the invention. It consists of a housing 1 in which a contact insert 2 is received, in which are used as contact elements sockets 4 and 5 pins. The can is closed in the unused state of a lid 3.
  • FIGS. 2A and 2B show a first embodiment of the invention
  • FIG. 2A shows a contact socket 4
  • FIG. 2B shows a contact pin 5 complementary to the contact socket.
  • the connection parts 10 comprise the contact socket 4 and the contact pin, respectively 5, a sleeve 12.
  • the connecting parts further comprise a C-shaped leaf spring 14, whose one end 15 is held in an anchoring groove 16 on the outside of the sleeve, and the other end 17 extends from the edge 18 of the sleeve in the opening 20 therein and a bias in the direction of the anchoring groove 16 opposite inner wall 22 of the sleeve 12 has.
  • the spring is preferably made of steel and has a sharp edge at its front end so that it slightly intersects the surface of a copper wire, and therefore provides resistance against the lead moving out of the contact position due to, for example, shaking motions.
  • the bore 26 of the corresponding pin of a plug is inserted.
  • FIG. 4 shows a section through a contact insert 2 with contact pins according to the exemplary embodiment of FIG. 2B. It can be seen that the spring 14 bears with its end 17 under tension on the inner wall 22 of the sleeve, so that a lead introduced into this position is held securely by the spring.
  • the contact element 5 has a fastening groove 24, by means of which it is latched in the contact insert 2 with corresponding latching projections 26.
  • connection part 10 and the clamping spring are shown in FIGS. 5A and 5B.
  • This embodiment is as well as the previously described embodiment for contact sockets (Figure 5A), as well as for contact pins ( Figure 5B).
  • a contact lug 30 extends parallel to its axis.
  • a clamping spring 32 is attached.
  • two clamping tabs 46 which are formed in the contact tab 30, engage around the longitudinal sides of the clamping spring 32 and clamp them against the contact tab 30.
  • the contact lug 30 is bent inwards at its upper end 40 and thus forms a stop 44 for the end of the clamping spring 32.
  • the clamping spring 32 consists of a flat metal strip. It is designed as a leg spring and bent to a V-shape. At the voltage applied to the contact tab 30 first leg 33 is followed by a relatively strong first bend 35 by about 150 °, and from that portion of the other, second leg 34 which is approximately at the same height with the upper end of the leg 33 follows a second bend 37 by about 90 °.
  • the clamping spring 32 has at its end an opening 38 which the upper end 40 of Contact tab 30 surrounds, so that the opening 38 delimiting end web 42 of the spring 32 is located on the outside of the contact tab 30 and is attracted to the contact surface 39.
  • the contact element shown in Figure 5B corresponds, apart from being a contact pin, otherwise the embodiment shown in Figure 5A.
  • FIG. 6A shows the embodiment according to FIG. 5A, wherein the spring for receiving a connecting wire 6 is compressed so that an opening is formed between the upper end 40 of the contact lug 30 and the end web 42 of the clamping spring 32, through which the stripped end 62 of FIG Connecting wire 6 is pushed through. If the spring 32 is relieved again, then in the figure 6, the end bar 42 is pulled by the spring tension to the left and clamps the wire end 62 to the contact surface 39 firmly.
  • FIG. 6B shows a modification of the exemplary embodiment according to FIGS. 5A, 6A, which facilitates the insertion of the connecting wire.
  • the end web 42 of the spring is angled upwards to the insertion direction of the wire. It is somewhat elongated relative to FIG. 5A and is at an acute angle to the contact surface 42.
  • the front end of the wire pushes the end ridge away from the contact surface due to the start-up bevel formed by the end ridge, thereby opening the spring 32.
  • the above-described contact elements may be made of compact material, but alternatively be designed as roll-stamped parts.
  • FIG. 7 shows a further exemplary embodiment, wherein in the contact insert contact elements according to the second exemplary embodiment according to FIGS 5B are used.
  • the contact insert is provided with a cover plate 50, which is preferably pivotally attached thereto.
  • a film hinge 58 are used, so that the contact insert and the cover plate 50 are integrally formed.
  • the cover plate 50 has bores 52 which are aligned with the connection parts of the contact elements and serve for insertion and secure positioning of the connection wires.
  • the terminal cover 50 is provided with paired holes 52, 54, wherein with respect to a contact element which serves a bore 52 for insertion of the lead wire and the other bore 54 allows to introduce a tool with the appropriate contact by bending the clamping spring again can be solved.
  • the tool can be a thin screwdriver or a steel pin.
  • the holes provided for the introduction of the tool are mounted so that they point to the upper bend 37 of the spring.
  • the cover plate 50 has two closure members 56 which are provided with latching projections which engage in the closed state of the cover plate behind corresponding locking strips 57 and hold the cover plate 50 in the closed position.
  • FIG. 8 shows the contact insert of FIG. 7 with closed cover plate.
