Abstract

A power relay for a vehicle, in particular a utility vehicle, is disclosed. The power relay contains a housing formed by a connecting base and a housing pot that is placed on the connecting base. Accordingly, two connecting bolts for establishing contact with an on-load circuit are formed by standard screws.

First claim

The invention claimed is:

1. A power relay for a vehicle, the power relay comprising:
a housing formed from a connection socket and a housing pot that is disposed on said connection socket, said connection socket having a receiving arrangement and connecting conductors; and
two connection bolts inserted into said connection socket so as to make contact with a load current circuit, said connection bolts each having a screw with a threaded shaft and a screw head, each of said connection bolts having said screw head disposed loosely in said receiving arrangement of said connection socket so that said threaded shaft protrudes outwards from said connection socket, each said screw head is encompassed on an outer face by one of said connecting conductors of said connection socket and consequently is held in a secure manner in said receiving arrangement.

2. The power relay according to claim 1 , wherein said screw head of each of said connection bolts has a non-circular outer contour.

3. The power relay according to claim 1 , wherein:
each of said connecting conductors has a bore hole formed therein in a central section and each of said connection bolts having said threaded shaft is guided through said bore hole; and
each of said connecting conductors have two fixing limbs with one of said fixing limbs disposed on each side of said central section, said fixing limbs are fixed in said connection socket.

4. The power relay according to claim 3 , wherein each of said connecting conductors having said fixing limbs is pressed into said connection socket.

5. The power relay according to claim 3 , wherein:
in each case said two fixing limbs of each of said connecting conductors protrude with a contact end into a housing inner space that is enclosed by said housing; and
each said contact end has in each case a contact element of a switching device for switching the load current circuit.

6. The power relay according to claim 5 , wherein said contact end of each of said connecting conductors is disposed in an inclined manner with respect to said central section so that said contact element that is disposed in each case on said contact end is disposed in an inclined manner with respect to a housing axis.

7. The power relay according to claim 5 , wherein said contact end of each of said connecting conductors is in each case bent towards one another.

8. The power relay according to claim 7 , further comprising filler elements, each of said connecting conductors is allocated one of said filler elements that is separate from said connection socket and that completely fills or at least surrounds at least around an edge of a volume that is encompassed by said connecting conductor.

9. The power relay according to claim 1 , wherein said connection socket is embodied as a component that is injection molded from a synthetic material.

10. The power relay according to claim 1 , wherein said screw head of each of said connection bolts has a hexagonal outer contour.
