Definitions

  • the invention relates to an electrical connector for Use with a mating connector, for example for use between a mating connector and an electrical control unit for an airbag (an inflatable restraint system) in one Motor vehicle.
  • an airbag an inflatable restraint system
  • Such a connector in which the mating connector Is part of a generator (a can with squib), is the subject of DE 195 13 358 C1.
  • a connector of the generic type has a tight limited size (for example: diameter about 1.5 cm).
  • plug and Mating connector can only be contacted if connector and Mating connector exactly like the associated contacts are positioned to each other.
  • a locking member is provided, which as coaxial to Housing arranged and axially displaceable on the housing Sleeve is formed.
  • DE 195 32 381 A1 describes an electrical connector a contacting element that can be inserted into a base body. In a latching position, the contacting element can a contact securing slide can be held.
  • the invention has for its object a connector of the type mentioned, the one hand Pre-assembly (pre-locking position) enables and on the other hand ensures that contact with the Mating connector is only possible when all components are exact are positioned to each other.
  • the invention is based on the finding that this is due to the special training of a locking member is possible.
  • the basic idea is so housing and locking member train that the locking member in two different locking positions (locking positions) the housing is attachable. In doing so, a first rest position should be used create a pre-locking position, but with the mating connector cannot be used in the connector. Only in one second rest position, at the same time ensuring that the cables and contacts in the housing are secure and the mating connector is to be kept be made possible.
  • the locking member can be on the side of the housing to be pushed on.
  • the locking member In the second latching position, the locking member is ready pushed onto the housing that the first end of the Locking member no longer in the housing opening protrudes. Now the mating connector can be plugged in and connector and mating connector can be contacted. The Locking member can no longer be removed, it is captively secured.
  • the locking member at its first end at least one L-shaped shoulder, whose free leg from the front in the direction of insertion Section of the locking member protrudes.
  • the short L-leg is inferior front, towards the housing opening. Will that Locking member laterally from above or via corresponding openings in the housing the projecting leg of the approach is guided into the Brought area of the housing opening.
  • the housing has an extension of the displacement of the locking member on the wall side Openings in which the free leg in another Displacement of the locking member relative to the housing is guided (second rest position).
  • the L-shaped lugs or lugs can be on the outside the housing contacts.
  • This embodiment is particularly useful when the locking member is U-shaped in section transverse to the axial direction M. Accordingly, the L-shaped approaches can then be extended the lateral U-legs run.
  • the locking member on the housing can also done in different ways.
  • the housing has 2 spaced apart on both sides Corresponding locking recordings arranged to each other.
  • the first snap-in receptacles in the insertion direction define the first stop position and the one behind it in the direction of insertion arranged snap-in receptacles the second locking position.
  • the first and the second latching position can be carried out accordingly lateral pressing of the locking member onto the housing can be achieved.
  • the result is together with the side U-legs a total of five in parallel and spaced sections of the Locking member.
  • the inner webs (framed by the U-legs) have following function:
  • Adjacent bars can have an associated one between them Get in touch and lead or define.
  • One embodiment provides that the outer webs in Extension of the L-shaped lugs towards the second End of the locking member and laterally next to the Arrange housing contacts. With two contacts then one further webs run between the housing contacts, so that each contact is delimited on both sides by a bridge.
  • Another form of training provides for the housing arms running parallel to the housing contacts form the spring towards the housing contacts are trained.
  • the webs (of the locking member) be aligned so that when you plug the Locking member on the housing in the second Locking position the spring arms and thus the contacts support. This also ensures that in the second locking position (where the connector is finished is assembled) the contacts are precisely aligned and are additionally secured (secondary locking of the contacts) and now the mating connector can be plugged on.
  • the thickening is arranged and spaced apart such that one of the thickenings in the assembled state of the connector in front and the other thickening immediately lies behind the aforementioned clamping areas.
  • the locking member on his second end several, parallel and spaced apart running webs (jaws) for clamping fixing of corresponding cable sections in the second locking position having.
  • those facing the cables Surfaces of the jaws should be profiled so that they corresponding cable sections positively and under Set static friction.
  • the invention is based on a Embodiment described in more detail.
  • the connector basically consists of the following components:
  • the housing 10 is at its left open one in FIG Housing end 121 is cylindrical in shape and has on its on the other end 12r essentially a rectangular cross section, being in the axial direction M of the connector on section 12r two locking edges 14, 16 are formed on each side.
  • locking edges 14, 16 serve to accommodate the Locking member (slide) 30, the side U-legs are marked with 32.
  • the U-legs 32 are cranked inwards at its free end. This will corresponding to the locking edges (locking receptacles) 14, 16 Locking means 34 formed.
  • first end 321 (in Figure 1: left) are in Extension of the U-legs 32 L-shaped lugs 36l, r to detect.
  • the free legs 38 stand to the left in the figure in front.
  • the legs 38 are in the open Housing end 121 (front housing part) slots 18 formed.
  • the locking member 30 is when placed on the housing 10 with the lugs 361, 36r and legs 38 in the slots 18 led.
  • the U-leg 32 of the locking member 30 on the rear Housing end 12r is first pressed radially outwards in order to then with the locking means 34 behind the snap corresponding locking edges 14 and so the to define the first stop position (FIG. 2).
  • FIG. 2 shows, the legs 38 protrude into the housing opening 12 and reduce the cross section.
  • a clip on one Mating connector is now not possible - according to the task.
  • the cables 50, 52 are in the rear housing part 12r bottom-side guides and protrude with their contacts 50k, 52k into the open housing end 121 (the open housing section). The exact positioning results from an overview of Figures 1 and 4 (for the second rest position).
  • the contacts 50k, 52k each have two, in the axial direction spaced thickenings 54, 56.
  • the front are Thickenings 54 in the housing section 121 and the rear Thickenings 56 in the housing section 12r.
  • FIG. 4 shows the positive reception of the cables 50, 52 between the jaws 42a to c in the assembled state of the Connector.
  • the housing 10 is lateral Spring arms 22 formed in the axial direction M of the Connector run and - as Figure 4 shows - to Housing end 121 over the area of the lugs 361, 36r and Leg: 38 protrude.
  • the spring arms 22 are laterally pushed away as soon as the Thickenings 54, 56, however, accumulate. Then the springs Arms 22 back (primary locking of the contacts).
  • FIG. 3 shows the connector in the second locking position of housing 10 and locking member 30.
  • the legs 38 now run in housing-side recesses 13 and Housing opening 12 is unimpeded for plugging the Mating connector free.
  • the mating connector blocks the Leg 38 so that the locking member is no longer (after above) can be removed from the housing 10. To the rear too (Axial) can no longer remove the locking member because the legs 38 in the corresponding recordings be held in the housing.
