Automotive electronics module

Claim 2

An automotive module for enclosing electronic circuitry therein for use in an automotive vehicle, comprising: a housing having a closed end and an open end and a receiving volume defined therebetween for receiving said circuitry therein, said open end including a circumferential edge extending therearound; connector means disposed in said housing for providing electrical connection between said module and said vehicle, said connector means including a circumferential lip extending therearound; and a cover for enclosing said housing and said connector means, said cover including a generally planar portion disposed in abutting surface contact with said circumferential edge of said housing and said circumferential lip of said connector means, said cover being welded to said housing along an abutting contact surface between aid planar portion and said circumferential edge by vibration welding.

Claim 3

An automotive module according to claim 1, wherein said cover is welded simultaneously to said circumferential lip and said circumferential edge along two weld contact surfaces by vibration welding.

Claim 4

An automotive module for enclosing electronic circuitry therein for use in an automotive vehicle, comprising: a housing having a closed end and an open end and a receiving volume defined therebetween for receiving said circuitry therein, said open end including a circumferential edge extending therearound; a connector disposed in said housing and adapted to provide electrical connection between said module and said vehicle, said connector including a circumferential lip extending therearound; and a cover for enclosing said housing and said connector, said cover including a generally planar portion disposed in abutting contact with said circumferential edge and said circumferential lip, said planar portion being adapted to form a pair of weld surfaces along respective abutting contact surfaces between said planar portion and said edge and lip when a force is applied to said cover in a direction parallel to the longitudinal axis of said housing and said housing and cover are linearly reciprocated relative to one another for a predetermined weld time interval under the application of said force, whereby said reciprocating motion causes thermoplastic material along said respective abutting contact surfaces to melt and upon cessation of said motion, said weld surface rigidifies simultaneously to hermetically seal said cover to said housing and said connector.

Claim 5

An automotive module for enclosing electronic circuitry therein for use in an automotive vehicle, comprising: a housing having a closed end and an open end and a receiving volume defined therebetween for receiving said circuitry therein, said open end including a circumferential edge extending therearound; a connector disposed in said housing and adapted to provide electrical connection between said module and said vehicle, said connector including a circumferential lip extending therearound; and a cover for enclosing said housing and said connector, said cover including a generally planar portion disposed in abutting contact with said circumferential edge and said circumferential lip, said planar portion being adapted to form a pair of weld surfaces along respective abutting contact surfaces between said planar portion and said edge and lip when a force is applied to said cover in a direction parallel to the longitudinal axis of said housing and said housing and cover are linearly reciprocated relative to one another for a predetermined weld time interval under the application of said force, whereby said reciprocating motion causes thermoplastic material along said respective abutting contact surfaces to melt and upon cessation of said motion, said weld surface rigidifies simultaneously to hermetically seal said cover to said housing and said connector.
