Abstract
An electrical device assembly and method to attach an isolated single stud fuse assembly to an electrical device are disclosed. The electrical device assembly consists of multiple studs, one or more of which is replaced with the isolated single stud fuse. A conductive copper landing zone receives an electrically isolated steel stud. When the landing pad assembly is orbital riveted into a plastic housing of the electrical device, the stud is locked into the housing permanently. Electrical devices such as disconnect switches and power distribution modules, both of which include multiple studs, are good candidates for being adapted with the single stud fuse assembly.
Claims20
An electrical device assembly comprising:
- an electrical device comprising:
- a first stud to be coupled to a first terminal;
- a receiving hole in a housing of the electrical device;
- and
- a single stud fuse assembly comprising:
- a single stud fuse comprising a shaft receptacle;
- a landing pad comprising a landing pad shaft and a stud base receptacle, the landing pad shaft to be orbitally riveted into the receiving hole of the housing;
- and
- an electrically isolated stud comprising a stud shaft and a stud base, wherein:
- the stud base is to be inserted into the stud base receptacle;
- the single stud fuse is disposed along the stud shaft, with the stud shaft being disposed through the shaft receptacle, the stud shaft to be coupled to a second terminal.
An electrical device comprising:
- a first stud and a first nut, wherein a terminal of a battery is to be placed over the first stud before securing the first nut;
- a pocket in a plastic housing of the electrical device;
- a busbar within a housing of the electrical device, the busbar being coupled to the first stud;
- a landing pad comprising a landing pad shaft and a rectangular receptacle, wherein the landing pad is orbital riveted into the pocket until the landing pad shaft is coupled to the busbar;
- and
- an electrically isolated stud comprising a stud shaft and a stud base, wherein the stud base fits into a side opening of the rectangular receptacle, the stud shaft to receive a single stud fuse and a second terminal of the battery.
An electrical device assembly comprising:
- an electrical device comprising:
- a first stud to be coupled to a first terminal of a second electronic device;
- a receiving hole in a plastic housing;
- a busbar comprising a first busbar portion and a second busbar portion, wherein the first busbar portion is coupled to the first stud;
- and
- a fuse assembly comprising:
- a fuse comprising a fusing element and a shaft receptacle, the shaft receptacle being disposed in a central location of a rectangular cubic housing and the fusing element being disposed along a side edge of the rectangular cubic housing;
- a landing pad shaft coupled to a stud base receptacle, wherein the landing pad shaft and the stud base receptacle are made from a metal piece made of electrically conductive material;
- and
- an electrically isolated stud comprising a stud base to be slid into a side opening of the stud base receptacle;
- wherein the landing pad shaft is disposed into the receiving hole such that the second busbar portion is coupled to the landing pad shaft.
