Embodiment Construction

[0019] figure 1 is a three-dimensional perspective view of the SRS connector system according to the present invention. The SRS connector system comprises a sealable squib connector 10 and a counter connector 40 provided with a plug-in protrusion 11 , a sealing expansion part 20 and a sealing ring 30 . Seal ring 30 may be an O-ring seal. The sealing ring 30 may be an elastic body made of synthetic rubber. In one aspect, the connector housing is provided with a base portion for receiving the connector cable and the male protrusion protrudes perpendicularly from the base portion of the housing.

[0020] Due to the expansion of the sealing ring, a reliable seal is established when the male protrusion is inserted into the mating connector receptacle. In this case, the sealing ring is dimensioned such that it is firmly and sealingly pressed against the inner wall of the mating socket.

[0021] As mentioned above, the sealable squib connector according to the invention is prefer...

Abstract

The invention relates to sealable squib connectors (10), in particular for airbag ignition systems. The connector comprises a connector housing with a plug-in projection (11), which plug-in projectionhas a mating face (16) at its distal end; a seal expansion element (20); and a resilient sealing ring (30) provided at the mating face of the plug-in projection between the mating face and the seal expansion element. The seal expansion element is being movable against the mating direction towards the mating face from an open position to a closed position thereby expanding the sealing ring.

Description

technical field [0001] The present invention relates to a sealable squib connector particularly for use with SRS (Safety Restraint System) systems. Background technique [0002] Squib connectors according to the prior art are generally formed from injection molded plastic parts and usually consist of a plug connector and a corresponding female counter connector. In many applications the electrical connection between a connector and its counter-connector must be protected from moisture and / or dust. This is especially critical for electrical connections that have important safety functions, such as the electrical connection between the squib connector and the reverse connector of an airbag ignition system. On the one hand, the sealing of the respective connection of the two connector parts must be reliable, and on the other hand the assembly of the two connectors should not be compromised. [0003] Sealable squib connectors according to the prior art consist, for example, of...
