Definitions

  • the invention is directed to one or both connecting parts of one two-part electrical connector, the connecting parts of two have mutually complementary housing.
  • One housing takes electrical contact parts, such as socket contacts, and is with a plug section provided that in the coupling case in a receiving section of the other housing is insertable. Because of its plug function this should Housing of the connector is referred to as "connector housing”.
  • the other housing assigned to it has a complementary receiving space for the plug section of the connector housing, which is why it is below should be called “socket housing” for short. This applies in the case of a coupling Plug housing with its plug section in the receiving section of the socket housing, which is why these mating ends of the Both connecting parts are referred to below as “coupling ends” should.
  • the socket housing is used to hold electrical mating contact parts, e.g. B. in the form of plug contacts.
  • the associated housing has at least two pairs of counter-contact parts side by side, axial housing chambers, in which the each an electrical line connected contact or counter contact parts, from the side facing away from the coupling end of the housing, into the Housing chambers are introduced.
  • the axial partition between the Housing chambers have the task of the two contact parts against each other isolate.
  • the housing of the known connector can have sealing problems bring out locking means for that of the contact parts in result in the housing chambers.
  • a movable across the housing chambers Latch with profiled openings in two positions in the housing can be locked.
  • a first locking position which is referred to as the "pre-locking position”
  • the opening profile of the bolt is the opening cross-section adapted to the housing chambers and allows the aforementioned axial insertion of the contact parts.
  • the “final locking position” the latch moves with its opening profile locks into the housing chambers and engages behind the contact parts radial shoulders.
  • the mating contact parts are in the final locking position fixed in the housing chambers, which is why they are no longer pull out of the housing chambers in the opposite direction to their insertion movement to let.
  • the invention has for its object to provide a well-shielded from the outside, inexpensive electrical connector which in the preamble of Claim 1 to develop the kind that is convenient, reliable Reversal movement of a locking the counter-contact parts in the die part Slider allowed and still saves parts and space is trained.
  • This is according to the invention by the in the characteristic of Claim 1 measures achieved, the following special Importance.
  • the one located between the two housing chambers axial partition the additional new function, namely as a slide to lock the inserted contact parts.
  • the additional new function namely as a slide to lock the inserted contact parts.
  • This detachable Part of the axial partition wall is hereinafter referred to as "partition wall piece" be named.
  • the partition wall piece has locking elements for the Contact parts radial protrusions.
  • the partition wall piece is namely shifted parallel to the wall on the inner surfaces of the recess and the recess only needs a sufficient recess height to show. Is the partition wall axially into the axial recess been inserted, it is then moved perpendicularly to over the pre-locked position, shifted to its final locked position become.
  • the recess advantageously has an opening profile, the bounding one Wall parts already in the pre-locking position of the partition piece Cover radial projections at least in some areas towards the receiving space.
  • the housing with the partition wall piece fixed in its pre-locked position then forms a prefabricated unit from captive, positionally secured Parts that can be delivered as a commercial product.
  • the locking position of the partition piece narrows its radial projections not clear cross-section of the housing chambers, which is why the customers of these units even insert the contact parts into the housing can.
  • Customers can choose the type and shape of the contact parts themselves and individually determine the electrical lines connected to it.
  • To secure the defined axial position of the contact parts in the housing chambers The customers only need the partition wall piece from the coupling end from, e.g. B. from the recording room to move laterally until the Final locking position of the partition piece becomes effective. Only then grab the radial projections of the partition piece lock behind the radial shoulders of the inserted contact parts.
  • the electrical connection consists of two couplable ones Connecting parts 10, 20, which, as Fig. 1 shows, both in terms of their electrical contact parts 11, 21 on both sides and also with respect to one another to be inserted coupling sections 14, 39 of their housings 13, 30 are complementary to each other. Any contact or counter contact part 11, 21 is connected to the conductor via a crimp connection or the like associated electrical line 12 or 22 connected in the coupling case of the two connecting parts 10, 20 electrically connected to one another in pairs should be.

  • plug section 14 Because of its plug function due to the plug section 14 is intended to be the housing of the first connecting part 10 in the following briefly “connector housing", however that of the second connecting part 20, because of the socket-like there Receiving section 36, abbreviated to "socket housing”.
  • the contact part in the plug housing 13 advantageously consists of a socket contact 11, while the mating contact parts 21 in the socket housing 30 are designed as plug contact parts 21 which with a pin end 23 in protrude into the receiving space 31 there.
  • the receiving space 31 is by a transverse to the longitudinal axis 33 of the housing 30 of FIG. 1
  • the appearance of the bottom wall 32 is from the front view of the socket housing in Fig. 3, where openings 35 for passage the connector pins 23 can be seen.
  • Through the bottom wall 32 is the housing 30 in the wide coupling portion 36 and a rear portion 34 structured. This rear section 34 of the socket housing 30 is radially offset from the preceding front section 36.
  • the two connecting parts engage in the coupling case 10, 20, the plug housing 13 with its plug section 14 in the Receiving space 31 of the socket housing 30.
  • the connector housing 13 can, for better sealing, a coat recognizable from Fig. 1 15 have, which encloses the plug section 14 in the radial distance. Between the jacket 15 and the plug-in section 14 form an annular space, in which the receiving portion 36 of the socket housing 30 of the other Connecting part 20 can penetrate.
  • the electrical contact points are on all sides to the outside shielded. If necessary, can also between the housings 13, 30 rubber seals are still used.
  • the connecting part 20 which, as can be seen from the exploded view of FIG. 2 is, apart from the counter-contact parts 21, only two further components consists, namely the already mentioned, one-piece socket housing 30 and a specially designed slider 40, which, as can be seen 7, the function of an insulating partition 38 in the socket housing 30 met.
  • the partition 38 namely separates in the rear section 34 two axial housing chambers 37 lying parallel to one another, which each serve to insert the counter-contact parts 21.

So owns the partition wall piece 40 latching-locking parts 18, which can be seen in FIG. 2 and 4, in the present case radially, on both sides of the guide rail 43, are arranged and each consist of a latch. As related Locking counter-locking parts serve two ribs 28, 29, which are adjacent Determine recesses. These recesses define the Latch 18, the respective height of the partition 40 in the axial recess 50. The two locking ribs 28, 29 are on the rear inner surface the channel-shaped extension 53 is formed in the socket housing 30.
