Abstract

A relay assembly configured for use in a vehicle electrical distribution center. The relay assembly includes a circuit board, a first and second relay disposed the circuit board and a plurality of terminals electrically coupled to the first and second relays. The relay assembly also includes removable fuses to protect the circuits controlled by the first and second relays against over-current conditions. In one embodiment, the relay assembly is packaged as a mini-ISO relay package.

Claims

1. A relay assembly, comprising:

a printed circuit board (PCB) having electrically conductive traces disposed on at least a first surface of the PCB;

a first relay having an electrically controlled switching circuit, said first relay mounted on said first surface and electrically coupled to said electrically conductive traces;

a second relay having an electrically controlled switching circuit, said second relay mounted on said first surface and electrically coupled to said electrically conductive traces;

a first electrically conductive terminal disposed on a second surface of the PCB and electrically coupled to said first relay;

a second electrically conductive terminal disposed on the second surface of the PCB and electrically coupled to said second relay, wherein said relay assembly is configured for use in a vehicle electrical distribution center; and

wherein said relay assembly further comprises;

a fusible link;

a third electrically conductive terminal electrically coupled to said first relay and said fusible link; and

a fourth electrically conductive terminal electrically coupled to said first electrically conductive terminal and the fusible link;

wherein the assembly further comprising a cover configured to enclose at least the first surface of the PCB, and said cover is characterized by the dimensions of 28 millimeters (mm) long by 28 mm wide by 25.5 mm high.

2. The relay assembly according to claim 1, wherein the first and second terminals protrude 11.5 mm from the second surface of the PCB.

3. The relay assembly according to claim 1, wherein the cover defines an opening configured to allow access to the fusible link.

4. The relay assembly according to claim 1, wherein the first and second relays are electromechanical relays.

5. The relay assembly according to claim 1, wherein the first and second relays are metal-oxide-semiconductor field-effect transistors.
