A compliant connector for a connection system in an internal combustion engine includes a cylindrical connector housing and a plurality of constant strain beam springs at one end of the connector housing to act as a self-centering/self-aligning mechanism in the connection system.

Compliant connector

An electrical connector is plugged onto an electrical device that has a hollow sleeve and an annular bonnet that has an outer electrical contact ring. The electrical connector includes an annular insulator, a lower elastomeric seal ring, a combination seal and contact member, a shielded conductor to carry an electrical signal out of the electrical connector and a flanged metal guard ring. The combination seal and contact member has a non-conductive elastomeric annulus and a conductive elastomeric portion that are co-molded to provide a unitary annular part. The annulus has a flanged upper end that is bonded to the flanged guard ring and a thinner lower end that has a plurality of axially spaced circumferential flexible sealing lips that biasingly engage the bonnet above the outer electrical contact ring. The conductive elastomeric portion is made of a non-conductive elastomeric material that has conductive particles widely dispersed throughout the material so that the conductive elastomeric portion exhibits a high electrical resistance in the uncompressed state that diminishes when the elastomeric portion is compressed by the outer electrical contact ring of the bonnet so that the conductive elastomeric portion acts as an electrical conductor that connects the contact ring and the conductor electrically. The lower elastomeric seal ring has a plurality of axially spaced flexible circumferential sealing lips that biasingly engage the bonnet so that the electrical connector sealingly engages the bonnet below as well as above the contact ring and the conductive elastomeric portion of the combination seal and contact member.

An illuminated elastomeric keypad switch assembly has an optical conductor on which a printed circuit is printed via electrically conductive ink and a keypad provided with translucent areas for passage of light. The optical conductor has recesses located adjacent the key caps whose width and depth progressively increases proceeding from the closest to the farthest key cap from a light source so that a uniform amount of light is transmitted through the key caps.

An illuminated elastomeric keypad switch assembly has a keypad and key caps which are illuminated by light passing through thin webs connecting the key caps to the keypad to create a halo lighting effect surrounding the key caps.

Halo lighting for keypad switch assemblies

A sealed electrical connector has an annular elastomeric seal pad which seals the openings of the terminal cavities as well as a bolt hole at the cable end of the connector. The seal pad is disposed in a well formed by an integral shroud of the connector body and the bolt hole extends through a bolt tower of the connector body which projects into the well.
