Definitions

  • the invention relates to an electrical connector, in particular for use between a can (squib) and an electrical control device for a restraint system in motor vehicles, for example an airbag.
  • Such a connector should have the smallest possible dimensions due to the small space available in restraint systems. It follows that individual components of the connector or the associated socket have only an extremely small size, but nevertheless in relation to the safety application (for example, belt tensioner, airbag) easy assembly on the one hand and high reliability on the other is required.
  • the safety application for example, belt tensioner, airbag
  • the known connectors have a controlled locking slide, which is locked in the initial position against actuation and can only be moved to its end position (locking position) when the connector is inserted into the socket (lighter).
  • the connectors are essentially made of plastic, wherein the controlled locking slide in the locked end position is at least partially under tension.
  • the object of the present invention is therefore to provide an electrical connector that can be solved even after a long time and put back together.
  • the basic idea of the present invention is to design the design and geometric arrangement as well as the interaction of the individual components in such a way that, at least in the end position or locked position of the connector, the controlled locking slide or the secondary locking means are largely stress-free or substantially relaxed for the Locking the connector worry.
  • a locking arm of the secondary locking means establishes the latching connection in the pre-locking position by at least one blocking rib, which interacts with the housing of the connector.
  • the secondary locking means formed from a base plate and of which substantially vertically extending functional elements (such as the actuator) can be arranged in an advantageous manner in an L-shaped design of the connector so that by pressure on the base plate, first the connector in the squib or Can with contact terminals is inserted and immediately thereafter by releasing a web on the actuator, the secondary locking means is immersed in the housing.
  • a shorting bridge can be opened by an opening finger on the secondary locking means.
  • a guide bar on the secondary locking means the release of the primary locking means can be prevented from the box by the guide bar engages behind the primary locking means.
  • this has four actuators with the corresponding webs and blocking ribs, wherein the actuators in advantageously arranged at the four corners of the base plate of the secondary locking means.
  • the design is further simplified and saves corresponding space by the actuator and primary locking means engage in the end position in the same recess of the box.
  • the recess is preferably formed as an internal annular groove.
  • locking means and housing are guided together in the preassembled position, then the locking means is released from the blocking position relative to the housing and can be moved relative to this.
  • the preassembly shown in Fig. 1a, 1b and 1c shows an electrical connector, consisting of a housing 10 and a secondary locking means 20 in the preassembled state on a can 50, also referred to as a squib or lighter.
  • the components are shown greatly enlarged and thus not true to scale.
  • the L-shaped plug shown in Fig. 1a for example, has a height of about 10 mm and a width of about 20 mm.
  • the secondary locking means 20 is arranged in the insertion direction S on a trunk 15 of the housing 10 and guided in the insertion direction S in the housing 10.
  • the housing 10 consists of the trunk 15 and a cigarette box-shaped shell. This leads contact elements, possibly via a welded throttle and a cable strain relief to other electrical components and has a separate cover 16.
  • the housing 10 may be formed in one piece or several pieces.
  • the secondary locking means 20 consists of a substantially rectangular, parallel to the plane of the housing 10 arranged base plate 20p having at its four corners in the insertion direction S extending actuators 22, a profile bar 21 and two arms 23, as shown in enlargement in Fig. 4 ,
  • the housing 10 has in its front, arranged above the trunk 15 portion recesses and indentations for the insertion, guiding and fixing of the secondary locking means 20.
  • the trunk 15 extends, which has a shape adapted to the box 50, in the present case cylindrical.
  • the actuator 22 is made of a material that allows a suspension of the actuator, such as plastic. On the actuator 22, which can also be referred to as a locking lance, are different Mounted projections that are important for the function of the secondary locking means 20.
  • the housing 10 has arranged next to the trunk 15 primary locking means 11, which also extend in the insertion direction S.
  • the primary locking means 11 are designed as two arms 11, at the end locking lugs 11r are mounted, which engage at a corresponding recess 55 of the box 50 for engagement when the plug is inserted into the socket 50.
  • the arms 11 are disposed in the end position between each two actuators 22 on the short side of the base plate 20p, wherein the arms 11 are mounted on the housing 10 and the actuators 22 on the secondary locking means 20.
  • Fig. 7 it can be seen that the central projection 25 has been moved past the housing 10 and is locked in the shown, latched end position of the lower projection 26 of the actuator 22 in the recess 55 of the box 50.
  • a second recess in the box 50 may be provided for the engagement of the lower projection 26.
  • the recess 55 of the box 50 may be configured as an annular groove.
  • the profile strip 21 provides for the interruption of a not illustrated here shorting bridge through the free end 21e of the profile strip 21.
  • the profile strip 21 also serves to guide the secondary locking means 20 in a correspondingly profiled recess or opening of the housing 10 and the box 50th
  • the arm 23 provides in the latched end position of the electrical connector for the locking of the primary locking means 11, by the arm 23 when inserting the Sekundärverriegelunbgsstoffs 20 between the proboscis 15 and the detent 11r facing away from the back of the primary locking means 11 is pushed.
  • a slide 23g of the arm 23 serves to further clarify the vertical guidance of the secondary locking means 20 in the housing 10 along the direction of insertion S.
  • the base plate 20p has on its underside recesses which engage in corresponding projections or ramps of the lid of the housing, so that the Sekundärverriegelsungstoff 20 substantially lies with the cover of the housing 10 in a plane.
