Definitions

  • the invention relates to a connector for pyrotechnic applications in motor vehicles, arranged in a housing contact sockets, with a primary lock for fixing a plug-in contact sockets into the contact plug and a secondary lock.
  • the secondary locking serves to secure the primary lock.
  • the durability requirements and in particular the reliability of such connectors are extremely high due to their field of application. Improvements in the reliability of the known connectors, not least due to the small dimensions, often at the expense of functionality.
  • the invention has for its object to provide a connector that is extremely reliable and not susceptible to environmental influences while maintaining the functionality of a secondary locking. This object is achieved with the features of claim 1.
  • a seal is provided according to the invention, which is arranged such that a relative displacement of the secondary locking relative to the seal while maintaining the sealing function is possible to move the secondary locking of the connector outside from a pre-locking position to a final locked position.
  • the inventive design of the connector it is possible pre-assembled the connector and deliver with pre-locked secondary lock. Already in this pre-locking position, the seal exerts its sealing function. According to the invention, the sealing function is not lost during the displacement of the secondary lock in the final locked position.
  • the secondary lock has an outer, preferably at least approximately circular cylindrical, in particular circumferential, sealing portion. Due to the circular cross-sectional geometry of the secondary locking a uniform stress distribution and thus an optimum sealing effect is achieved.
  • the seal has a radially inwardly encircling sealing bead which rests against the sealing portion of the secondary locking.
  • the inner cross section of the sealing bead is complementary in shape to the outer contour of the sealing portion. In a sealing section with a circular cross section of the cross section of the sealing bead is therefore also circular. In this case, the inner diameter of the sealing bead in the unassembled state should be smaller than the outer diameter of the sealing section.
  • the area of the secondary locking mechanism enclosed by the sealing portion is designed to be closed.
  • this area may be formed trough-shaped and at the same time serve as an actuating portion to move the secondary locking of the connector outside to its final locked position.
  • the secondary locking mechanism has an axial stop, preferably annular shoulder, for engagement with the seal in the final locking position. In the final locked position so that the seal is not only in the radial, but also in the axial direction of the secondary lock, which leads to improved Abdichtrisen.
  • the sealing geometry of the secondary locking seal is integrated in a housing seal.
  • the seal is the Secondary lock formed integrally with the housing seal.
  • the seal of the secondary lock and the housing seal is produced by molding the connector with a permanently elastic material, in particular polyurethane, in a common manufacturing step.
  • the later seal for the secondary locking (sealing bead) in the overmolding tool can be cleared by stamp.
  • the necessary openings for the secondary locking in the housing are closed by stamp, whereupon the secondary locking seal is then formed. This seal is then applied against the sealing portion of the subsequently assembled secondary locking under bias.
  • the connector has a proboscis area for receiving a contact plug and that in the region of the proboscis a, in particular circumferential, seal is provided for the contact plug.
  • a seal for the contact plug in the trunk area for example, lighters can be contacted, which have a standard insulating ring with shorting bridge and coding area.
  • About the shorting bridge of the connector can be queried in an embodiment of the invention, the correct position of the seal. For this purpose, it is only necessary to measure electrically, whether the contacts are short-circuited or not. The contacts are no longer short-circuited after moving the secondary latch in its final locked position. Since the secondary lock can only be moved to its final locked position when the contact plug is inserted, the determination that there is no short circuit serves as an indicator for an inserted and sealed contact plug.
  • the housing comprises two, in particular latchable components between which a circumferential tongue and groove connection is provided. This protects the interior of the connector from the high pressure sealant.
  • a connector 1 for airbags is shown.
  • the connector 1 consists of a housing 2 in which two contact sockets 3, 4 are arranged. In the contact bushes partially gold-plated, resilient contacts 3a, 4a are introduced. Each contact 3a, 4a is electrically connected to an opening into the housing, electrical line 5, 6.
  • the contact sockets 3, 4 with the contacts 3a, 4a are used to receive a contact plug, not shown.
  • the connector 1 is provided with a secondary lock 8.
  • the secondary lock 8 can be moved linearly into the housing 2 between a pre-engaged position shown in FIGS. 4 to 6 into a final locked position shown in FIGS. 1 to 3. As a result, a primary lock 9 is secured for fixing the plug contact, not shown.
  • the secondary lock 8 is provided at its lower end in the plane of the drawing with a push-button mechanism known per se, which takes over the actual securing function of the primary lock 9. Furthermore, in the longitudinal direction and parallel to the push-button mechanism 10 extending guide extensions 11 are provided, which are guided in corresponding guides 12 (see FIG. 8) in the housing 2. In its upper area in the plane of the drawing (FIG. 7), the secondary lock 8 has a circumferential annular shoulder 13 projecting radially outwards. Below the annular shoulder 13 includes in the axial direction of a circular cylindrical, circumferential sealing portion 14 at.
  • the housing 2 is encased by a housing seal 15.
  • the upper region of the housing seal 15, which is shown in FIGS. 2 and 5, is formed as a secondary locking seal 16 with a circumferential sealing bead 17 projecting radially inwards.
  • the sealing bead 17 of the secondary locking seal 16 lies radially both in the pre-locking position (FIGS. 4 to 6) and in the final locking position (FIGS. 1 to 3) sealingly against the circular cylindrical sealing portion 14 of the secondary lock 8 under pretension.
  • the outer diameter of the sealing portion 14 of the secondary lock 8 is dimensioned larger than the inner diameter of the sealing bead 17 of the secondary locking seal 16 in the unassembled state.
  • the underside of the annular shoulder 13 is additionally located axially on the sealing bead 17.
  • the sealing effect is improved in the final locked position.
  • a so-called trunk area 18 is provided on the side opposite the secondary locking gasket 16 side of the connector.
  • a circumferential outer seal 19 is provided in the trunk area 18, a circumferential outer seal 19 is provided with radially inwardly facing sealing bead 20. At the trunk area 18 with outer seal 19 contact plug can be sealed.
  • the housing seal 15, the secondary locking seal 16 and the outer seal 19 of the proboscis area 18 are integrally formed.
  • a sealing material polyurethane is provided in the present embodiment. However, other suitable permanently elastic materials may be used.
  • the sealing of the connector 1 takes place by molding the housing 2 with the sealing material.
  • the assembly of the secondary lock 8 takes place after the extrusion process.
  • the housing 2 consists of a lower spring body 21 shown in FIG. 8 and an upper spring body 22 which can be placed thereon and shown in FIG. 9.
  • a groove 23 running around the edge is introduced into the lower spring body 21.
  • On the inside of the upper spring body 22 shown in FIG. 9 is a circumferential, complementary to the groove 23, encircling spring 24 integrally formed.
  • the spring 24 engages in the groove 23 and prevents sealing material from penetrating into the interior of the connector 1 during the encapsulation process.
  • a latching mechanism is provided consisting of latching projections 25 and this encompassing detent spring 26.
  • 2 centering ribs 27 are integrally formed on the circumference of the housing for the extrusion process with sealing material.
  • the spring bodies 21, 22 may also be designed to overlap each other.
  • the transfer of the secondary latch 16 from its pre-locked position into its final locked position works only when the lighter is plugged in. An intended between the contacts 3a and 4a shorting bridge is unlocked. As a result, it can be electrically closed to the position of the seal. If the secondary lock 8 is in its final locked position, then the contact plug is necessarily inserted and, due to the peripheral outer seal 19, sealed to the outside.
