Abstract
A power distribution contactor mount, and a power distribution system incorporating the same, include a plurality of electrically and thermally conductive contactor posts operable to connect a contactor lead to a bus bar, a mounting panel face, wherein each of the contactor posts is received in the mounting panel face and extends through the mounting panel face, and a first heat dissipation component mounted on the mounting panel face and thermally connected to each of the contactor posts. The thermal connection is via a thermally conductive and electrically insulative polymer insert, and each of the posts protrudes through the first heat dissipation component.

A power distribution system comprising:
- a bus bar contactor having a contactor circuit, the bus bar contactor including a plurality of contactor leads, a plurality of electrically and thermally conductive contactor posts operable to connect said contactor leads to a bus bar;
- a hollow thermal ground plate including a mounting panel face, wherein each of said contactor posts is received in said mounting panel face and protrudes through said mounting panel face;
- and
- said hollow thermal ground plate being thermally connected to each of said contactor posts via at least one of a plurality of a thermally conductive and electrically insulative polymer inserts, wherein each of said posts protrudes through a side of said hollow thermal ground plate opposite to said mounting panel face.
A power distribution contactor mount comprising:
- a plurality of electrically and thermally conductive contactor posts operable to connect contactor leads to a bus bar;
