Abstract

An adapter is provided for electrically connecting a printed circuit board to an airbag accelerometer. The adapter includes a leadframe housing to which is joined a leadframe, as, for example, by embedding the leadframe within the leadframe housing during insert molding thereof. The leadframe includes connector tails which extend in a first direction for connection to a printed circuit board and facing segments which face in a second direction for connection to an airbag accelerometer. The first and second directions are angularly disposed relative to each other. An adjuster assembly which includes such an adjuster is also provided.

Claims

1. An adapter for use in electrically connecting accelerometer leads of an airbag accelerometer to a printed circuit board, said airbag accelerometer having a horizontal mounting plane and said printed circuit board having a printed circuit board mounting plane which is disposed at an angle relative to said horizontal mounting plane, comprising:

a leadframe housing; and

a leadframe embedded within said leadframe housing, said leadframe comprising a plurality of printed circuit board connecting tails which extend in a first direction and a plurality of airbag accelerometer facing segments, each facing segment being comprised of apertures which extend through said leadframe and being disposed so as to face in a second direction, said second direction being oriented at an angle relative to said first direction, said leadframe housing further comprising a plurality of openings exposing respective ones of said plurality of facing segments.

2. The adapter of claim 1 wherein said leadframe housing comprises first and second mounting bushings, each mounting bushing having a mounting axis which extends in said first direction.

3. The adapter of claim 1 further including an alignment member extending from said leadframe housing in said first direction.

4. The adapter of claim 3 wherein said alignment member comprises a snap fastener.

5. The adapter of claim 1 wherein said leadframe housing comprises first and second mounting bushings, each mounting bushing having a mounting axis which extends in said first direction.

6. The adapter of claim 5 further including an alignment member extending from said leadframe housing in said first direction.

7. The adapter of claim 6 wherein said alignment member comprises a snap fastener.

8. The adapter of claim 1 wherein said angle is substantially 90°

.

9. An adapter assembly, comprising:

a leadframe housing;

a leadframe joined to said leadframe housing, said leadframe comprising a of airbag accelerometer facing segments, each facing segment being disposed so as to face in a second direction, said second direction being oriented at an angle relative to said first direction;

an airbag accelerometer having a horizontal mounting plane, and a plurality of accelerometer leads, accelerometer leads of said plurality of accelerometer leads being electrically and mechanically connected to respective facing segments; and

a printed circuit board having a mounting plane which is disposed at an angle relative to said horizontal mounting plane, connecting tails of said plurality of connecting tails being electrically and mechanically connected to said circuit board.

10. The adapter assembly of claim 9 wherein said leadframe is embedded within said leadframe housing, said housing comprising a plurality of openings exposing respective ones of said plurality of facing segments to respective ones of said accelerometer leads.

11. The adapter assembly of claim 10 wherein facing segments of said plurality of facing segments comprise apertures which extend through said leadframe, respective ones of said accelerometer leads extending through respective ones of said apertures.

12. The adapter assembly of claim 9 wherein said leadframe housing comprises first and second mounting bushings, each mounting bushing having a mounting axis which extends in said first direction, a fastener extending through a respective bushing and mechanically attaching said leadframe housing to said printed circuit board.

13. The adapter assembly of claim 9 wherein said leadframe housing comprises an alignment member which extends from said leadframe housing in said first direction and mates with an alignment aperture which extends through said printed circuit board.

14. The adapter assembly of claim 13 wherein said alignment member comprises a snap fastener which attaches said leadframe housing to said printed circuit board.

15. The adapter assembly of claim 9 wherein said angle is substantially 90°
