Definitions

  • the invention relates to a socket which is provided with an open on both sides, with one of the open sides to be mounted on a surface and a detachably mounted contact insert, which contact insert comprises a support part connected to the housing and a detachably mounted contact carrier.
  • a socket is known from European Patent 0 460 370 and is mounted, for example, on motor vehicles to which a trailer is to be coupled.
  • This known socket has a number of advantages over a conventional socket, the socket being made in one piece.
  • the dimensions of the contact insert are relatively large, since it has a supporting function and must distribute the forces which occur when the contact plug is inserted, for example a socket holder, rear or rear bumper of a motor vehicle connected to a trailer coupling, on which the Socket is mounted. Due to the relatively large support surface required for this purpose, the contact insert is not suitable for being inserted through an opening in this base into the housing mounted thereon. This means that to mount and connect the socket, the cables to be connected must first be pulled through a relatively small opening in the ground and then the individual wires must be connected to the corresponding contacts of the contact insert, after which the contact insert and the housing connected and fastened to the ground.
  • a problem with this is that the connection of the individual wires to the contacts, particularly in the case of multi-pole sockets, such as the thirteen-pole sockets for use in trailers for motor vehicles is very time consuming. As a result, such a conventional socket is generally not suitable for being installed in the assembly line during the production of the vehicle.
  • the contact insert is constructed from a support part with relatively large dimensions and a relatively small contact carrier accommodated therein. Due to the small size of the contact carrier, it is suitable for being pushed into the support part through an opening in the base, after which the support part and the contact carrier can be pushed together into the housing and the socket thus formed can be fastened as a whole. This makes it possible to connect the contact carrier to the wiring in the vehicle beforehand, which considerably shortens the installation time of the socket.
  • the contact carrier can be manufactured as a whole with the required wiring by a supplier and can be supplied as a complete and tested part.
  • the support part is formed by a central ring, which is connected on two sides to a joint with a half ring with corresponding ones, the two half rings each having two support points.
  • the contact insert is now produced by inserting the contact carrier through the ring up to a stop edge thereof, and then pivoting the two half rings around the joints towards one another so that they close around the contact carrier, after which the two half rings are snap-fastened be connected to the center ring of the support part.
  • the contact insert thus formed which consists of the contact carrier and the "folded" support part around it, is then in the housing is received, the legs of the support part in the assembled state coinciding with the lower edge of the housing.
  • the force exerted on the contact carrier when a contact plug is inserted into the socket is distributed by the support part to the legs, which then transmit this force to the ground.
  • this socket is a significant improvement over the conventional socket described above, it still has some disadvantages.
  • the assembly of the contact carrier and the support part to form a contact insert is relatively complex because the two half rings have to be pivoted around the contact carrier and then connected to the central ring of the support part.
  • the support part which completely surrounds the contact carrier, takes up a relatively large amount of space in the part of the housing facing the ground, which space is of great importance, in particular in the case of a multi-pole contact, especially for accommodating the cabling.
  • This known socket also has no devices for straightening the support part. This can mean that when installing the contact insert in the socket, the legs are aligned with an opening, for example with a wire bushing, in the wall of the socket, as a result of which the legs find insufficient support and cannot perform their force-transmitting function.
  • the invention therefore aims to create a socket of the type described in the introduction, but these disadvantages do not arise.
  • the support part has the shape of a dimensionally stable ring with at least one leg which is arranged essentially concentrically with respect to the longitudinal axis of the ring and defines a support surface and a number of clamping members which cooperate with the contact carrier and are distributed over the circumference of the ring.
  • Preferred embodiments of the socket according to the invention are the subject of dependent claims 2 to 6 inclusive.
  • the invention also relates to a contact insert, a support part and a housing for use in a socket, as described above.
  • a socket 1 ( Figure 2) is provided with a housing 2 which is open on both sides and which can be mounted on a base 4 with a single one of the open sides 8.
  • a detachable contact insert 2 is attached, which consists of a support part 6 connected to the housing 2 and a contact carrier 5 detachably mounted in the support part 6.
  • the housing 2 is fastened with screws 7 to the base 4, which can be, for example, the rear or the rear bumper of a vehicle.
  • the open side 9 of the housing 2 facing away from the base 4 is closed with a cover 10 which is pivotable about an articulation axis 11 connected to the housing 2, and by means of a Spring 12 is biased in its closed position.
  • the contact carrier 5 is formed by a clamping cover 13 and a receiving part 21 (FIG. 1A).
  • the clamping cover 13 is provided with a series of openings 14, through which the individual contacts 17 can be inserted.
  • Each opening 14 is closed at its end facing the receiving part 21 by a number of circular segment resilient flexible cams 15 which engage around a tapered part 16 of each contact 17.
  • the cams 15 are somewhat beveled towards their free ends ( Figure 2), whereby a self-centering effect is achieved.
  • a wire 19 is connected to each contact 17, one end 18 of which is inserted into a receiving space 64 of the contact 17 and is clamped therein by compressing the tapered part 16.
  • Each contact 17 further comprises an opening receiving space 20 facing away from the wire 19, in which a leg of a contact plug (not shown here) is received.
  • the receiving part 21 of the contact carrier 5 is provided with a number of through openings 22 for receiving the contacts 17. These openings open into the end face 24 of the receiving part 21. In its front face, the receiving part 21 is provided with two alignment pins 23 which cooperate with alignment openings (not shown here) in the clamping cover 13, whereby this cover 13 only in one way on the receiving part 21 can be postponed. This ensures your correct positioning of the contacts 17 in the contact carrier 5.
  • the openings 22 have a somewhat widened neck into which the spring cams 15 of the clamping cover 13 fit (FIG. 2).
  • the spring cams 15 are enclosed by the openings in such a way that they cannot be pressed apart and thus the contacts 17 are enclosed in the cover 13 as soon as the cover 13 and the receiving part 21 are connected to one another.
  • the receiving part 21 has one Shoulder 25, the function of which will become clear below.
  • a series of clamping arms 26 protrude from the shoulder 25, each of which is provided with a rib segment 27, which rib segments 27 form a snap connection with a circumferential rib 28 on an insertion part 29 of the clamping cover 13 when the clamping cover 13 and the receiving part 21 are pushed into one another will. This pushing these two parts into each other can only take place after contact pins 17 are all attached in the openings 14 of the cover 13.
  • the receiving part 21 is further provided with a centering groove 30 which interacts with a centering cam 31 (FIG. 1B) of the support part 6.
  • the support part 6 has the shape of a dimensionally stable ring 32 with a number, in the example shown two legs 35 mounted concentrically with respect to a longitudinal axis of the ring 32. Each leg 35 defines a support surface 36 which, in the assembled state of the socket 1 on the Base 4 supports ( Figure 2).
  • the support part 6 also has a number, in the example shown three, distributed over its circumference, clamping members 38 which cooperate with the contact carrier 5.
  • the clamping members 38 have the shape of hook arms, the hook lugs 39 of which are directed towards the longitudinal axis of the ring 32 and engage behind the clamping cover 13 of the contact carrier 5 when it is fitted in the support part 6.
  • Recesses 37 are provided between the legs 35, which can serve as a cable bushing in the case in which the wiring does not have to be routed through the ground, but to one side of the housing 2.
  • the hook arms 38 which are resiliently flexible, each have a pressure surface 40, which is opposite the hook nose 39, and projects beyond the circumference of the support ring 32. These pressure surfaces 40 are provided with parts of the Housing 2 cooperate to secure the hook arms 38 against bending when the contact carrier 5 is engaged in the support member 6.
  • the support part 6 is further provided with clamping cams 41 with which the support part 6 can be clamped in the housing 2.
  • the support part 6 has an outstanding centering cam 42 for cooperation with a centering groove provided in the housing, as a result of which the support part can only be received in the housing 2 in one way.
  • the support part 6 is also provided with a rubber cover ring 43 which has an opening 63 which is aligned with the opening 33 of the support part 6. The contact carrier 5 can thus be pushed through the support part 6 and the sealing ring 43 until its shoulder 25 comes into engagement with the edge of the opening 33 of the support part 6, the hook arms 38 then being bent out by the contact with the shoulder 25, just with their hook lugs 39 just past the end face of the clamping cover 13, and thus spring back, whereby the contact carrier 5 is clamped in the support part 6.
  • the housing 2 is provided with three cylindrical walls 46, which determine receiving spaces 45 for the fastening elements or screws 7.
  • the position of these recording rooms is standardized.
  • the position of the hook arms 38 in the support part 6 is selected so that they are just aligned with the cylinder walls 46.
  • the pressure surfaces 40 with the walls 46 are under attack, as a result of which the hook arms 38 are secured against bending.
  • Around one of the cylinder walls 46 two centering ribs 47 are attached, which together define a centering groove 48.
  • the protruding centering cam 42 of the support part 6 is received in this centering groove 48, as a result of which the contact insert 3, which is formed by the contact carrier 5 and the support part 6, can only be received in the housing 2 in a single manner and, moreover, is held in a rotationally secure manner becomes.
  • the housing 2 further comprises a sleeve 44 surrounding its opening 9, which is provided with an inwardly projecting stop edge 49 to which the support part 6 comes to rest in the assembled state. Between the cuff 44 and the outside of the housing 2 there is a free space 50 in which an electrical switching unit 57 can be accommodated, whereby, for example, the rear fog lights of the vehicle to which the socket 1 is attached can be automatically switched off when there is an on Trailer is coupled.
  • two lower trestles 51 are mounted in the space 50, in which a rocker arm can be pivoted.
  • the rocker arm 52 has a tab 53 which projects through an opening 54 in the sleeve 44 into the opening 9 of the housing 2.
  • the rocker arm 52 also has an operating part 55 which interacts with a microswitch 56 which is accommodated in a housing 57 of the switching unit.
  • the housing 57 with the microswitch 56 is clamped in the free space 50 in the vicinity of the rocker arm 52.
  • the switch housing 57 is provided with a cam 58 which falls into a recess 59 in the sleeve 44.
  • the tab 53 of the rocker arm 52 which is inserted into the opening 9 is pressed outward, as a result of which the rocker arm 52 pivots about its axis 60 and the operating part 55 is moved to the microswitch 56 and operates it. This can then interrupt the power supply to, for example, the rear fog lights of the vehicle.
  • the switch unit 57 By making the switch unit 57 divided, the microswitch can be easily replaced if necessary.
  • the assembly of the socket 1 according to the invention thus runs extremely quickly due to its specific construction.
  • the contact carrier 5 is supplied by a supplier in a fully assembled and wired form, it is sufficient to place it in the underground 4 to provide an opening through which the contact carrier 5 can be inserted, whereupon this contact carrier can be snapped into the support ring 6 and the support ring 6 can in turn be clamped in the housing 2.
  • the housing 2 is then fastened to the base 4 with screws 7, the support surfaces 36 of the support part 6 coming to rest flush with the underside of the housing 2 on the base.
  • the force that is exerted when a plug is inserted into the socket is guided directly into the base 4 via the support part 6.
