Definitions

  • the invention relates to a multi-pole electrical plug-in device according to the preamble of claim 1.
  • the connector has a housing designed as a handle shell, in which a contact carrier is mounted.
  • the contact carrier has, in accordance with the number of poles of the plug-in device, arranged in rows receiving chambers, in each of which a contact element is inserted.
  • Each of the contact elements is connected via a connection section to a cable.
  • the connector has a resting on the contact carrier, the receiving chambers covering the sealing plate made of rubber or gel material, which is pressable by means of a pressure plate against the contact carrier and the lines in a sealing manner.
  • the plug-in connector has a peripheral sealing element mounted radially on the contact carrier with radially directed sealing lips.
  • the sealing lips are detected by a sleeve-shaped collar of the mating connector and partially deflected in a continued merge movement in a closing path to the end position in the axial direction.
  • a multipolar electrical plug-in device By Patent Abstracts of Japan Vol. 1995, No. 11, 26 December 1995 (1995-12-26) & JP 07 226256 A (AMP), August 22, 1995 (1995-08-22) is known a multipolar electrical plug-in device.
  • This has a connector which is reversibly coupled with a mating connector of the connector in an axially extending plug-in direction
  • the connector has axially extending receiving chambers for contact elements, which open into a contact space through which the electrical coupling of the connector is made with the mating connector, said seals seal the contact space.
  • a compensation element in the form of a hole in the connector while the contact space is pressure compensated.
  • the object of the invention is to simplify the production of a compensating element for pressure equalization in a multi-pole electrical connector.
  • the compensation element of the outer contour of a contact element is at least as far as approximated that it can be mounted like a contact element.
  • the compensation element can be fitted and mounted in a technically favorable manner.
  • An embodiment of the invention is embodied in the drawing and explained in more detail in the following description. It shows the figure in a sectional view of a multi-pole electrical plug-in device with a connector and a mating connector shown mating.
  • a multi-pole electrical plug-in device 11 shown in the figure has a connector 12 which is releasably coupled to a mating connector 13.
  • the connector 12 is a movable harness connector and the mating connector 13 is designed as a stationary power strip in a controller.
  • the plug-in device 11 is provided in particular for use in the automotive industry.
  • the connector 12 has a designed as a grip shell housing 14 which is formed on the inside as a contact carrier 16.
  • the contact carrier 16 like the rest of the housing 14, consists of an electrically insulating plastic.
  • the contact carrier 16 contains multi-row receiving chambers 17 which the contact carrier 16 in the axial direction, concurrently with an arrow 18, the Plug-in direction of the connector 12 on the mating connector 13 reproduces, penetrate.
  • each of the receiving chambers 17 is in the direction of arrow 18 depending on a contact element 19, of which only a single schematisier is shown, can be used.
  • the contact element 19 has the end, directed to the mating connector 13, a contact portion 21 and is connected at the other end in a manner not shown to a roped electrical cable 22.
  • Each of the contact elements 19 is secured in the associated receiving chamber 17 against an axial extension by primary locking elements 23 in the form of locking tongues of the contact element 19 and by a secondary locking element 24 in the form of a partially engaging in the receiving chambers 17 locking slide.
  • the connector 12 has a partially resting on a top 26 of the contact carrier 16 sealing plate as a first sealing member 27 made of rubber or gelartigem material by means of an adjacent pressure plate 28 by mounting a connector 12 spanning cover 29 against the upper side 26 and against the guided through the sealing plate 27 cable 22 is sealingly pressed.
  • the cables 22 may also be sealed by bellows-type single-wire seals which can be inserted in the direction of the arrow 18 into the receiving chambers 17 for prestressed contact with the cables 22 or the contact elements 19.
  • the contact carrier 16 on the outside a circumferential second Seal member 31 on which radially directed sealing lips 32 are formed to form a radial seal 33.
  • the sealing lips 32 are detected by a sleeve-shaped collar 34 of the mating connector 13 and partially deflected in the axial direction in opposite directions to the arrow 18 spring-back.
  • a compensation element 37 which is inserted along a receiving chamber 17 in the contact carrier 16 and opens between pressure plate 28 and cover 29 in a cable compartment 38 as a compensation chamber 39, a volume reduction associated with the air displacement from the contact space 36 is made possible without significant resistance.
  • the cable compartment 38 is not sealed to the environment, so that ambient pressure prevails here. However, it is largely protected by the lid 29 from splashing water and dirt.
  • the compensation element 37 may be designed as a valve which opens only at a pressure surplus in the contact space 36 with respect to the ambient pressure.
  • the compensation element 37 may be formed as a continuous tube in the form of a bypass, so that even when you open the connector 11 by pulling the connector 12 of the mating connector 13 against the direction of the arrow 18 no opening of the connector 11 inhibiting negative pressure in the Form contact space 36, since in this embodiment of the compensating element 37 of the pressure equalization takes place constantly on both sides.
  • the compensating element 37 has the outer shape of a contact element 19. It can thus be equipped and mounted like a contact element 19 in manufacturing technology favorable manner.
  • the compensating element 37 is not limited to attachment along a receiving chamber 17. It can, for example, also run within the wall of the contact carrier 16 and, beginning at the contact space 36, lead to the cable space 38 or to another point on the plug connector 12, where ambient pressure also prevails.
