Definitions

  • the invention relates to a coding device for a two-part, multi-pole electrical connector, in which two connector housings which can be separated from one another, namely a socket housing and a pin housing, are connected to one another so as to be pivotable about a pivot axis.
  • an electrical contacting device for. B. a motor vehicle, sit in corresponding openings of a plate-shaped carrier, for. B. a retaining plate, next to each other several identical electrical connectors, each consisting of a socket housing and an associated pin housing, which are assembled for electrical contacting of electrical lines and separated from each other to remove the contact. Since, as a rule, several housings are formed uniformly, coding devices must be provided for the unmistakable assembly, which prevent that housings that do not belong together are connected to one another during assembly or during inspections, in which the plug connector housings of a plug connector are separated and then reassembled.
  • coding z. B edges, pins or the like projections at certain points of a connector housing that fit into corresponding recesses in the associated mating housing.
  • These coding means are simple molded parts for connectors whose housings are plugged together with a straight-line plug movement.
  • a connector with coding means and two housing parts which are joined together in the area of a common swivel axis and plugged together with a circular swivel movement about the swivel axis.
  • a swivel axis web which is provided on a housing part of the connector and bears against a swivel channel which is attached to the other housing part of the connector, serves as the articulated connection.
  • the housing part with the swivel axis channel is extended beyond the joint area and provided on the inside with a dovetail-shaped groove for fixing coding elements.
  • the pivot axis is connected to a holder on the housing part, which in turn has a dovetail-shaped groove on the side remote from the housing for receiving coding elements.
  • the coding elements are used releasably and interact with the coding elements on the housing part of the swivel axis trough. These coding elements ensure that only housing parts can be joined together with corresponding coding elements and pivoted accordingly.
  • This codable connector is complex to manufacture, since devices for attaching the coding elements must be provided in the region of the swivel joint.
  • the coding device increases the space requirement of the connector considerably, since it extends considerably beyond the swivel joint.
  • EP 0 119 951 A1 and DE 37 44 277 A1 describe codable plug connectors which consist of two housing parts, the socket part and the plug part, which are connected on one side via a swivel joint.
  • a coding unit is arranged between the swivel joint and the area of the sockets or plugs, which prevents incorrect contact when the plug connectors are closed by plugging together housing parts that do not belong together.
  • the object of the invention is to provide a coding device for a two-part, multi-pole electrical connector, in which two connector housings are connected to one another so as to be pivotable about a swivel axis, in such a way that the coding device is easy to shape and functions reliably even after a long period of operation, even when it is assembled the connector housing takes effect and enables a compact design of the connector.
  • the connector shown as an example has a cuboid plug housing 1 and a cuboid socket housing 2.
  • the socket housing 2 is covered by a cable duct 3, which is arranged locked on the latter.
  • the pin housing 1 is formed by two side walls 5, 6 of an end wall 7 and a rear wall 8. In the interior of the plug pin housing 1, separated by chamber walls, several open contact chambers 9 extending from the plug surface 2 facing the socket housing 2 to the cable outlet surface 11 facing away from the socket housing 2 are arranged side by side.
  • the plug-in surface 10 is overhanged by a cuboid-shaped space 4, the side walls 12, 13 of which are aligned with the side walls 5, 6 of the plug-in pin housing 1 and the end wall 14 a with corresponding side-wall regions protrudes over the end wall 7 of the plug-in pin housing 1.
  • a rear wall corresponding to the rear wall 8 of the pin housing 1 is not provided in the frame 4, nevertheless the side walls 12, 13 project beyond the rear wall 8 of the pin housing 1 a little.
  • cantilevered area 14 sits between the side walls 12, 13 above the level of the plug-in surface 10, a pivot axis web 15, the task of which is explained below.
  • Two coding webs 23, 24 of a coding device according to the invention extend from the swivel axis web 15 to the rear wall 8 and are aligned parallel to one another and arranged at a certain distance from one another.
  • the dimensions of the socket housing 2 accommodated in the frame 4 correspond to the pin housing 1. It has corresponding side walls 16, 17 (see FIG. 5), an end wall 18 and a rear wall 19 (see FIG. 2).
  • the socket housing 2 is also penetrated by open contact chambers 20 which extend continuously from the cable outlet surface 21 to the plug surface 22 and are flush with the contact chambers 9 when the housing 1 and 2 of the connector are assembled.
  • electrical contact elements (not shown), namely z. B. in the housing 1 contact pins and in the housing 2 contact sockets, which are connected to electrical cables (not shown) from the cable outlet surfaces 11,21 come out of the housing chambers.
  • the joining of the housings 1 and 2 leads to the electrical contacting of the electrical contact elements.
  • a pivoting groove 25 which extends parallel to the rear wall plane at a distance from the rear wall and is open to the outside and upwards, namely between correspondingly extended regions of the side walls 16, 17 and expediently in the tapering free end region of one of the rear wall 19 in the area of the cable exit surface 21, starting at an incline outwardly in the direction of the plug-in surface 22 and at a distance from the rear wall 19, the channel wall 26a.
  • the swivel channel 25 has coding slots 26, 27 perpendicular to its longitudinal extent, which can protrude into the channel wall 26 a, the distance and the dimensions of the slots corresponding to the distance and the dimensions of the coding webs 23, 24 and the coding slots 26, 27 from the Coding webs 23, 24 are penetrated approximately in a form-fitting manner when the swivel channel 25 engages under the swivel web 15 for joining the housings 1 and 2 together.
  • the locking means are expediently arranged between the end wall 14 a of the frame 4 and the end wall 18 of the housing 2 and z.
  • B. consist of a resilient, connected to the end wall 18, a locking lug 30 having locking tongue 29 and a molded on the end wall 14 a locking edge 31.
  • housing 1 sit z. B. side by side in a support plate (not shown).
  • Each housing has coding bars at different distances and, if necessary, also with different thicknesses.
  • the coding webs and coding slots fit into one another in a form-fitting manner and thus additionally offer a lateral support for the swiveling device which stabilizes the swiveling device.
  • the coding device according to the invention can be varied with regard to the thickness of the coding webs or the width of the coding slots, the number of coding webs and the coding slots and with regard to the spacing of these elements from one another, so that a large number of codings is possible.
  • the coding also takes place when the housing is plugged together before pivoting, so that it can be immediately recognized whether the correct housing has been used. This allows assembly time to be saved.
  • the coding device according to the invention is also robust because the webs and slots are fixed and supported components that do not break out or break off.
  • the coding elements are not arranged exposed, but are housed in the area within the housing.
