Definitions

  • the invention relates to an electrical connector with a housing, with at least one contact element inserted into a contact chamber of the housing, with a locking device which can be fixed on the insertion side for the contact elements on the housing and which can bring at least one contact element into engagement with the contact element by insertion into the contact chamber Has locking arm and has the passage options for the contact elements with a damaged line.
  • Such a connector is known from DE-A-1 790 043. It is a multi-pole plug connection, the housing of which is formed by a plastic disc which has cavities for receiving contact elements. On the line side, each cavity has an enlarged recess.
  • the locking device also consists of a plastic disc which has projecting plastic fingers which are inserted into the recesses when the two discs are joined together. The fingers protrude into the clear width of the cavity which is provided for guiding the contact element. Since the fingers are designed to be resilient, they are pushed back into the recess when the contact element is inserted into the cavity.
  • the fingers of the plastic disk forming the locking device can spring back into the recess behind the step of the inserted contact element and in this way the contact element in the Secure the plastic disk that forms the housing.
  • the plastic disk forming the locking device has passage possibilities in the form of through openings for the contact elements or the struck lines.
  • the publication does not state how the two disks are attached to one another.
  • a disadvantage of the known plug connection is that the holding of the contact elements is ensured solely by the elasticity of the plastic fingers. As a result, inadequate locking of the contact elements in the housing is achieved in many applications.
  • the present invention is therefore based on the object of developing an electrical connector of the generic type in such a way that the clamping force of the locking device for the individual contact elements is increased and thus a better positional fixation in the contact chambers is achieved.
  • the electrical connector has a locking device 1 with locking elements 2 and locking elements 3, the locking elements 2 cooperating with counter-locking elements 4 arranged on the outside of the housing walls 5 of a housing 28.
  • the locking device 1 made of plastic is adapted to the contours of a contact chamber 12 to be locked in the housing 28.
  • it consists of a closed frame 7 which is rectangular in plan view (FIG. 2), the frame webs 7a, 7b, 7c and 7d of which are also rectangular in cross section.
  • two pin-shaped locking arms 8 which are expediently rectangular in cross-section, project vertically downwards in a parallel manner and are formed as locking elements 3, spaced apart from one another symmetrically to the center of the web 7d, and the frame web 7d protrude approximately twice as long. In the same opposite arrangement there are locking arms 8 on the frame web 7b.
  • a locking bracket 9 is seated as the locking element 2.
  • the locking bracket 9 consists of two bracket arms 10, which are spaced apart from each other parallel to one another and perpendicularly downward in cross-section and are preferably rectangular in cross section, which are connected to one another at the end via a crossbar 11.
  • the locking bracket 9 projects beyond the frame web 7d with approximately the same length as the locking arms 8.
  • An identical locking bracket 9 sits on the outer surface of the frame web 7b.
  • the locking device 1 is plugged onto the housing 28, which has the contact chamber 12, into which an electrical contact element 13 is placed, which is crimped onto a line 14.
  • Such crimped contact elements 13 generally have an edge at the front end of a wire claw 15. In the example shown, this edge consists of a transverse web 16.
  • the contact element 13 has a latching tongue 17 which, when inserted, engages behind a latching step edge 18 in the contact chamber 12 (FIG. 4).
  • the wall thickness of the frame 7 of the locking device 1 corresponds to the wall thickness of the housing wall 5. Accordingly, the locking device 1 fits on the housing 28 by the housing wall 5 in each case between the Locking bracket 9 and the locking arms 8 formed column 19 is pushed (Fig. 3) until the lower edge 20 of the frame 7 is seated on the upper edge 21 of the housing 28 (Fig. 4).
  • the locking brackets 9 find the counter-locking elements 4 on the respective outer surface of the housing wall 5, i.e. in each case a web-shaped, first counter-latching element 22 and also a web-shaped, second counter-latching element 23, which are arranged at a distance from one another and from the top edge 21 and parallel to this.
  • the counter-locking elements 22, 23 interact with the crossbar 11 of the respective locking bracket 9, accordingly the length of the counter-locking elements 22, 23 is shorter than the lateral distance between the bracket arms 10.
  • the crossbar 11 of the locking bracket 9 can be due to the elastic Pivotal movement of the bracket arms 10 slide over the first counter-locking element 22 until it springs back behind it and sits between the two counter-locking elements 22 and 23. Since the spacing of the counter-locking elements 22, 23 from each other corresponds approximately to the width of the crossbar 11, the crossbar 11 and thus the locking device 1 are fixed in the pre-locking position (FIG. 3).
  • the locking arms 8 arranged on the opposite frame webs 7b and 7d extend parallel to one another into the contact chamber 12.
  • the crimped contact element 13 can be inserted into the contact chamber 12 through an insertion opening 12b without hindrance .
  • the locking device 1 for the final locking position is pressed further on the housing 28 until the crosspiece 11 snaps over the second counter-locking element 23 and engages behind the latter, the edges 20, 21 being seated one on top of the other (FIG. 4).
  • the surface of the second counter-locking element 23, viewed in cross section, is designed as a rounded contact surface 23a, so that the run-up slope of the crossbar 11 can slide more easily over the first counter-locking element 22 than over the second counter-locking element 23.
  • the locking arms 8 act like a pair of pliers when the final locking position is reached by gripping the wire claw 15 and thereby fixing the contact element 13 in position.
  • the locking arms 8 have a locking effect in the end latching position because their front edges prevent the contact element 13 from being pulled out of the contact chamber 12 by the front edges of the locking arms 8 abutting the crossbar 16 or a similar edge of the contact element 13.
  • the invention thus shows a completely different way of locking a contact element in a housing and fixing or jamming it with the locking device.
  • the locking works because almost every contact element has an edge in the transition area from its claw part to the contact part.
  • the overall length of the housing is not extended because the housing can be shortened according to the length of the frame 7.
  • the production of the locking device 1 is simple because it is an uncomplicated plastic part.
  • the housing 28 can also be of simple construction because the locking device 1 requires simple, corresponding active elements (run-up slopes and counter-locking elements).
  • the rounded run-on surface 23a of the counter-locking element 23 is advantageous, since it provides the crossbar 11 with a greater resistance than the run-up bevel 24 of the first counter-locking element 22.
  • the run-up slope 26 can expediently be placed closer to the insertion opening 12b than shown in the drawing, so that the locking arms 8 are already in contact with the run-up slope 26 in the pre-locking position (FIG. 3).
  • the locking arms 8 are chamfered inward in the region of the insertion opening 12b and thereby form insertion bevels 8a which facilitate the insertion of the contact element 13. It is essential that the locking device 1 provides a very considerable simplification of the automatic assembly of a housing 28. There is no longer any need to apply pivoting movements as with a hinged lid; the housing can be locked with a simple, straightforward movement.
