Abstract
A power distribution block includes a housing, an input terminal and at least one output terminal extending from the housing. At least one fuse insertion opening is formed in the housing and configured for insertion of a fuse. Each fuse insertion opening includes a first fuse contact terminal and a second fuse contact terminal within and configured for electrical contact with an inserted fuse, and each first fuse contact terminal is coupled to the input terminal. The power distribution block also includes at least one relay each having a first relay contact and a second relay contact where each first relay contact is coupled to a respective one of the second fuse contact terminals, and each second relay contact is coupled to a respective one of the output terminals.
Claims35
A power distribution block comprising:
- a single housing integrally formed with a plurality of fuse insertion receptacles and at least one switch element receptacle;
- a first fuse contact terminal and a second fuse contact terminal within each of said plurality of fuse insertion receptacles;
- a power input terminal extending from said housing, the first fuse contact terminal in each of the fuse insertion receptacles being mechanically and electrically connected to the power input terminal;
- a switching element substantially enclosed within the at least one switch element receptacle, the switching element comprising a first contact and a second contact, the second fuse contact terminals in each of the fuse insertion receptacles being mechanically and electrically connected to the first contact of the switching element;
- and
- a power output terminal extending from said housing, said second contact of the switching element being mechanically and electrically connected to said power output terminal.
A power distribution block comprising:
- a housing having a plurality of fuse insertion receptacles and at least one fuse output receptacle integrally formed therein;
- a power input terminal extending from said housing;
- and
- first and second fuse output terminals extending from said housing within said fuse output receptacle;
- and
- each of the fuse insertion receptacles comprising a first fuse contact terminal and a second fuse contact terminal, the first and second fuse contact terminals each including contact blades projecting from the housing, each of the first fuse contact terminals mechanically and electrically connected to the input terminal, and each of the second fuse contact terminals mechanically and electrically coupled to respective ones of the first and second fuse output terminals.
A power distribution system comprising:
- a fuse block comprising:
- a single housing defining a plurality of integrally formed fuse insertion receptacles and a plurality of fuse output receptacles;
- a power input terminal extending from said housing;
- fuse output terminal blades extending from said housing within the fuse output receptacles;
- and
- pairs of fuse contact terminal blades each respectively located in the fuse insertion receptacles;
- wherein one of each pair of the fuse contact terminal blades is mechanically and electrically connected to the power input terminal, and the other of each pair of the fuse contact terminal blades is mechanically and electrically connected to one of the fuse output terminal blades;
- and
- a plurality of female fuses each comprising a first fuse contact and a second fuse contact, the plurality of female fuses being insertable into the fuse insertion receptacles with the first and second fuse contacts receiving the pair of fuse contact terminal blades.
