Abstract

A contactor assembly post is provided. The contactor assembly post includes a first portion electrically connected to an external bus bar at an exterior of an electrical contactor housing, a second portion electrically connected to an internal bus bar at the exterior of the electrical contactor housing, a third portion and fins. The internal bus bar is configured to extend into an interior of the electrical contactor housing to be electrically coupled to another internal bus bar. The third portion extends transversely between the first and second portions. The fins extend transversely from multiple points defined along a longitudinal axis of the third portion.

First claim

What is claimed is:

1. A contactor assembly, comprising:
internal bus bars;
external bus bars respectively associated with the internal bus bars;
posts respectively supportive of the internal bus bars and respectively electrically interposed between corresponding pairs of associated external and internal bus bars,
each post comprising portions respectively connected to the external and internal bus bars of the corresponding pair and fins extending from between the portions;
a solenoid;
a movable bus bar which is movable by the solenoid into a first position at which the internal bus bars are electrically coupled via the movable bus bar or a second position at which the internal bus bars are decoupled; and
at least one of corrugated fins or flexible straps extending between the movable bus bar and the housing and straight fins extending from the movable bus bar to the exterior of the housing.

2. The contactor assembly according to claim 1 , further comprising a panel to which the posts are supportively coupled.

3. The contactor assembly according to claim 1 , wherein the portions and fins of each post are oriented substantially vertically.

4. The contactor assembly according to claim 1 , wherein one of the portions of each post are metallurgically bonded to or integrally connected with the external and internal bus bars.

5. The contactor assembly according to claim 1 , wherein:
the internal bus bars comprise multiple internal bus bars,
the external bus bars comprise multiple external bus bars, and
the portions of each post are respectively connected to single ones of the multiple external and internal bus bars.

6. The contactor assembly according to claim 1 , wherein:
the internal bus bars comprise multiple internal bus bars,
the external bus bars comprise multiple external bus bars, and
the portions of each post are respectively connected to all of the multiple external and internal bus bars.

7. The contactor assembly according to claim 1 , wherein the posts respectively comprise an insulating outer layer.

8. A contactor assembly, comprising:
an electrical contactor comprising a housing defining an interior and internal bus bars that extend into the interior from an exterior of the housing,
the electrical contactor being operable in first and second modes in which the internal bus bars are electrically coupled and decoupled, respectively, in the interior;
external bus bars respectively associated with the internal bus bars;
posts respectively supportive of the internal bus bars and respectively electrically interposed between corresponding pairs of associated external and internal bus bars,
each post comprising first and second portions respectively connected to the external and internal bus bars of the corresponding pair at the exterior of the housing, a third portion extending between the first and second portions and fins extending from the third portion;
a solenoid;
a movable bus bar which is movable by the solenoid into a first position at which the internal bus bars are electrically coupled via the movable bus bar or a second position at which the internal bus bars are decoupled; and
at least one of corrugated fins or flexible straps extending between the movable bus bar and the housing and straight fins extending from the movable bus bar to the exterior of the housing.

9. The contactor assembly according to claim 8 , further comprising a panel to which the posts are supportively coupled.

10. The contactor assembly according to claim 8 , wherein the first and second portions of each post are oriented substantially vertically, the third portion of each post is oriented substantially horizontally and the fins of each post are oriented substantially vertically.

11. The contactor assembly according to claim 8 , wherein the first or second portions of each post are respectively metallurgically bonded to or integrally connected with the external and internal bus bars.

12. The contactor assembly according to claim 8 , wherein:
the internal bus bars comprise multiple internal bus bars at opposite sides of the housing,
the external bus bars comprise multiple external bus bars at opposite sides of the housing, and
the first and second portions of each post are respectively connected to single ones of the multiple external and internal bus bars.

13. The contactor assembly according to claim 8 , wherein:
the internal bus bars comprise multiple internal bus bars at opposite sides of the housing,
the external bus bars comprise multiple external bus bars at opposite sides of the housing, and
the first and second portions of each post are respectively connected to all of the multiple external and internal bus bars.

14. The contactor assembly according to claim 8 , wherein the posts respectively comprise an insulating outer layer.
