Abstract

An electrical connection structure for connecting an electronic control unit 7, for example in an anti-lock braking system (ABS) or a traction control system, to magnetic valves 2,3, or other load, features a novel plug-and-socket structure which eliminates some of the conventional wiring harness. Magnetic valves 2, 3 are attached on one side to a housing 4 and feature, on their opposing faces, prongs 6 which engage counter-contacts 18 on electronics unit 7, which thus attaches directly to the valve unit. Electronics unit 7 also has sockets to receive contact pins 22 of a relay 23. Electronics unit 7 and valve housing 4 mate in such a way that relay 23 cannot be accidentally unplugged and is protected from environmental influences.

Claims

1. Apparatus for secure electrical connection of an electronic control and power output unit (7) to a power consuming unit (2,3) in a motor vehicle, wherein

said consuming unit comprises at least one magnetically actuated hydraulic valve (2,3);

said consuming unit (2,3) has plug contacts (6);

said electronic unit (7) has mating counter-contacts (18);

said electronic unit and consuming unit plug together at a plug/socket connection (28) and assume positions immediately adjacent one another;

and wherein said at least one valve (2,3) is mounted on an outer wall (5) of a valve-receiving housing (4), and said electronics unit (7) has a protective wall (30) which extends to said outer wall and surrounds said at least one valve.

2. Apparatus according to claim 1, wherein said housing (4) and said electronic unit (7) form therebetween a cavity (37) which accommodates a connecting element (33) of a plug-contact device (32) for connection to the electronic unit.

3. Apparatus according to claim 2, wherein the connecting element (33) is releasably mounted in correct alignment on said valve-receiving housing (4).

4. Apparatus according to claim 3, wherein a positioning channel (42) is formed in said electronic unit (7) for insertion of said connecting element (33).

5. Apparatus for secure electrical connection of a controlling electronic control and power output unit (7) to a controlled power consuming unit (2,3) in a motor vehicle, wherein

the consuming unit comprises at least one magnetically actuated hydraulic valve (2,3);

the consuming unit (2,3) has plug contacts (6);

the electronic unit (7) has mating counter-contacts (18); and

said electronic unit and consuming unit plug together at a plug/socket connection (28) and assume positions immediately adjacent one another; and

wherein said electronic unit (7) and consuming unit plug together with a pluggable switch means (23) interposed therebetween, and thereby secure said switch means against accidental disconnection.
