In close contact with the insert 43 of the assembly 40, the locking projections 35a, 35b of the igniter power supply connector 1 are fastened to a customized locking groove 46 formed on the wall of the igniter assembly 40.

이 경우 본 발명에 따른 점화기 전기공급 커넥터(1)는 적어도 2 개의 탄성편(30a, 30b)이 장착되어, 외부의 힘이 어느 한 탄성편, 예컨데 탄성편(30a)의 누름부(33a)에 전달되어 하나의 잠금돌기(35a)가 잠금홈(46)으로부터 이탈되었을 경우라도 다른 탄성편(30b)의 잠금돌기(35b)가 잠금홈(46)으로부터 이탈되지 않는다.In this case, the igniter electrical supply connector 1 according to the present invention is equipped with at least two elastic pieces 30a and 30b, and an external force is applied to any one of the elastic pieces, for example, the pressing portion 33a of the elastic piece 30a. Even when one lock projection 35a is transmitted and released from the lock groove 46, the lock protrusion 35b of the other elastic piece 30b is not separated from the lock groove 46.

즉, 의도되지 않은 외부 힘이 아니라 사용자가 반드시 의도된 힘으로써 두개의 누름부(33a, 33b)를 동시에 눌러야 점화기 전기공급 커넥터(1)와 점화기조립체(40)를 서로 분리할 수 있게 되므로 점화기 전기공급 커넥터(1)와 점화기조립체(40)가 의도하게 않게 분리되는 것을 막아 차량 에어백 시스템의 안정성이 현저히 증가하게 된다. That is, the igniter electrical supply connector 1 and the igniter assembly 40 may be separated from each other by pressing the two pressing parts 33a and 33b at the same time as the intended force rather than the unintentional external force. Preventing the inadvertent separation of the supply connector 1 and the igniter assembly 40 significantly increases the stability of the vehicle airbag system.

본 발명은 상기 실시예를 기준으로 주로 설명되어졌으나, 발명의 요지와 범 위를 벗어나지 않고 많은 다른 가능한 수정과 변형이 이루어 질 수 있다. 예컨데, 각 탄성편(30) 사이의 각도의 변경, 탄성편(30) 개수의 특정, 탄성편(30), 잠금돌기(35), 잠금홈(46)등의 형상의 단순한 변경등은 당업자가 용이하게 도출할 수 있는 변경일 것이다. Although the present invention has been described primarily with reference to the above embodiments, many other possible modifications and variations can be made without departing from the spirit and scope of the invention. For example, the change of the angle between each elastic piece 30, the specific number of the elastic piece 30, the simple change of the shape of the elastic piece 30, the locking projection 35, the locking groove 46, etc. It will be a change that can be easily derived.

본 발명에 따른 차량 에어백용 점화기 전원공급 커넥터는 사용자가 의도하지 않은 힘이 점화기 전기공급 커넥터의 탄성편을 미는 힘이 발생하더라도 탄성편이 점화기어셈블리의 삽입부로부터 이탈되지 않으므로, 차량 에어백시스템의 안정성이 현저히 증대되는 효과가 있다. In the vehicle airbag igniter power supply connector according to the present invention, even if a force that is not intended by the user to push the elastic piece of the igniter electrical supply connector is not released from the insert portion of the igniter assembly, the stability of the vehicle airbag system There is a significant increase in effect.

비록 본 발명이 상기에서 언급한 바람직한 실시예와 관련하여 설명되어졌지만, 본 발명의 요지와 범위로 부터 벗어남이 없이 다른 다양한 수정 및 변형이 가능한 것은 당업자라면 용이하게 인식할 수 있을 것이며, 이러한 변경 및 수정은 모두 첨부된 특허청구의 범위에 속함은 자명하다.Although the present invention has been described in connection with the above-mentioned preferred embodiments, it will be readily apparent to those skilled in the art that various other modifications and variations can be made without departing from the spirit and scope of the invention. It is obvious that all modifications fall within the scope of the appended claims.
