ABSTRACT:
A connector assembly for an anti-skid hydraulic braking system comprises a bulkhead connector extending through an aperture in a sidewall of the brake fluid reservoir, a connector harness mounted along the inside of the reservoir sidewalls extending from the bulkhead connector to three solenoid assemblies mounted on the reservoir floor, and a solenoid connector one each solenoid assembly in engagement with the connector harness. The solenoids extend through floor apertures into the master cylinder to respective hydraulic lines extending to brake cylinders in the wheels, one of the solenoids handling both rear wheels. The bulkhead connector mates with a connector outside the reservoir which is terminated to a wire harness connected to the on-board microprocessor to relay current to the solenoids when data from individual wheel speed sensors is processed to determine that a particular wheel is about to skid. The solenoid for that wheel is then instantaneously actuated to momentarily decrease hydraulic pressure in that wheel's brake fluid line. The connector harness is planar and can be bent around corners between adjoining sidewalls of the reservoir. Contact sections on path members of the harness are exposed to be engaged by spring arm contact sections of the bulkhead connector and the individual solenoid connectors. The harness is made by overmolding spaced cover portions over a stamped lead frame and then severing the individual path members from each other, and the path members can be bent between the cover portions.
