Definitions

  • the invention relates to an electrical plug-in connector with an elongated metallic connector frame, which can be fixed to a device housing or the like and is formed from a frame front part and a frame rear part, a two-part insulating body enclosed between the two frame parts with a multiplicity of bores for receiving a multiplicity of them Insulating body mounted contact elements in the form of plug pins, sockets or the like., Which are connected to the rear of the connector to electrical lines and on the front of the connector combined into a multiple connector, plugged into a connecting cable mating contact elements, the insulating body a front, the holes for the front ends of the contact elements having support and guide plate made of thermoplastic material and a rear plate with corresponding holes for the rear ends of the contact elements.
  • Plug contact connectors of this type have found widespread use in practice under the name of D-sub connectors; their dimensions and polar patterns are e.g. B. standardized in DIN 41652 and MS 18274 and MS 18276. The degree of protection of such connectors corresponds at least to the classification IP 54 specified in DIN 40050.
  • the known D-Sub connector with two-part insulating body not only the front but also the back plate is molded from thermoplastic material and designed so that contact elements for crimping technology in it can be fixed mechanically.
  • the invention has for its object to further develop the electrical plug-in connector of the type mentioned that a relatively simple manufacturing measures a water and dust protected version, in which the contact elements with their respective front ends still have a balance allowing small tolerances mobility and in which the contact elements can also be inserted and fixed in the bores of the insulating material body even after the cables have been struck, without impairing the sealing effect.
  • the plug-in connector according to the invention in which this object is achieved, is essentially characterized in that the rear plate is designed as a sealing plate made of rubber-elastic plastic and thus in relation to the surface facing it, the support abutting the outwardly bent flange of the frame front part. and the guide plate is dimensioned so that it supports itself with its edge area facing away from the support and guide plate after connecting the two frame parts to one another while ensuring a perfect seal on an inwardly drawn support edge of the frame rear part, and that ring grooves with support switches for receiving are inserted in the holes penetrating the sealing plate radially projecting annular shoulders of the contact elements, which serve to secure the position of the contact elements in the inserted state, are provided.
  • annular groove extending concentrically to this bore is provided in the sealing plate at a distance from each bore receiving a contact element, into which a correspondingly dimensioned, axially projecting annular bead of the support and engages the guide plate.
  • the illustrated connector comprises an elongated connector frame 1 with a frame front part 2 and a frame rear part 3.
  • Fig. 2 shows that the plug contact connector has the known D-sub connector configuration.
  • a two-part insulating material body is clamped between the two frame parts 2, 3.
  • This consists of a front support and guide plate 4, z. B. made of thermoplastic and a rear sealing plate 5 made of rubber-elastic plastic, for example an isomer or neoprene.
  • Both plates 4, 5 of the insulating body are provided with a multiplicity of bores for receiving a corresponding multiplicity of contact elements in the form of plug pins (not shown), sockets 6 or coax contacts 7 or, similarly, concentrically constructed high-current contacts (not shown), which - as well the sockets 6 - are each provided with a large number of contact springs which ensure low contact resistance.
  • the contact elements can be connected to a connecting cable in a known manner. This can be done by soldering, specifically in the area of a solder cup 8, in the area 9 using crimping technology or on the back of the coax contact elements via conventional coax connecting parts; 2 shows a usual spout 10 in this connection.
  • Fig. 3 shows that the support and guide plate 4 in the vicinity of the two frame parts 2, 3 common parting plane 11 abuts an outwardly bent flange 12 of the front frame part 2.
  • the rear plate designed as a sealing plate 5 is dimensioned in relation to the surface of the frame front part 2 facing it in such a way that with its edge region 13 facing away from the support and guide plate 4 after connection of both frame parts 2, 3 in the region of their common parting plane 11 supports an inwardly drawn support edge 14 of the frame rear part 3.
  • the sealing plate 5 is under a prestress, which ensures the perfect seal even over a long period of time.
  • Fig. 3 shows that the contact elements 6 are provided with two radially projecting ring shoulders 15, 16. These are used to secure the position of the contact elements 6 in the associated bores of the sealing plate 5 by inserting them after they have been inserted into the holes on support shoulders 17, 18, which are formed by annular grooves in the holes, come to rest.
  • the bores in the sealing plate 5 are provided in the region of their mouths facing the corresponding bores in the front-side support and guide plate 4 with a bore constriction 19, 20 formed by a reduction in diameter.
  • these bore areas of the sealing plate 5 are widened by radial displacement and lead to a tight embracing of the contact elements.
  • annular groove 22 is provided at a distance from each hole in the sealing plate 5 and extends concentrically to this hole.
  • a correspondingly dimensioned, axially projecting annular bead 23 of the support and guide plate 4 engages in this annular groove 22.
  • the practically unyielding thermoplastic material of the support and guide plate 4 provides support for the rubber-elastic material around the bore area on the mouth side.
  • the axially parallel section of the support and guide plate is of course not required since the pins extend freely in the direction of the plane determined by the upper edge of the frame front part.
  • the upper boundary plane of the support and guide plate ends approximately in the area of the common parting plane 11 of the two frame parts 2, 3.
