Abstract
An improved IDC trim resistor connector assembly made up of a generally open top cup shape connector with side wall slots and an interior first array of terminal posts arranged for passage therethrough of a first lead wire of sensor circuitry. A first stamped metal IDC terminal is push-on mounted on the terminal posts for IDC cradling and electrically and mechanically receiving and connecting to the first lead wire. A conventional trim resistor substrate is loose mounted but accurately positioned on the connector bottom wall and has an "E" pattern of resistive material adapted for center leg laser trimming to calibrate the associated sensor circuitry. A first IDC terminal spring leg overlap contacts one side leg of the trim resistor E-pattern and thereby spring clamps the resistor substrate. A cover is snap-latch mounted on the connector and has an access opening to enable laser trimming of the trim resistor after cover installation. One end of a second lead wire is received in a second IDC metal terminal in turn mounted on a second array of connector-interior terminal posts and also having a spring leg overlap electrically contacting and clamping the other E-pattern side leg.
