Abstract:
Trim resistor connector assembly comprising in combination a connector of generally open top cup shape having a bottom wall and a peripheral side wall with side wall slots to accommodate passage therethrough of a first lead wire of sensor circuitry, a first array of terminal posts on said bottom wall arranged within the interior of the connector housing, a first stamped metal terminal push-on assembly mounted on said terminal posts and adapted to cradle the first lead wire therebetween, a trim resistor, having a substrate mounted on the bottom wall of said connector and having a resistive conductive composition material arranged in a pattern thereon for laser trimming and calibration of circuitry to be associated with said trim resistor connector assembly, said first terminal having a first spring arm adapted to lap a first portion of said trim resistor material and to clamp said resistor substrate in place on said connector bottom wall in assembly, a cover adapted to be mounted onto said connector to cover the same, said cover having an access opening in registry with the trim resistor substrate as positioned interiorly of said connector to enable laser trimming and circuit calibration by access to said trim resistor substrate through said cover opening, and second lead wire electrical coupling means mounted in said connector and adapted for electrically connecting a second lead wire to a second portion of said trim resistor material on said substrate whereby said trim resistor is adapted to provide a conductive laser-trimmable resistance path between the first and second lead wires in assembly and operation of the connector assembly in an electrical system.
