Abstract
Abstract A heat dissipator useful in conjunction with a circuit breaker which has a plurality of terminals, each of which may have an electric cable connected thereto by a connector, includes electrically and thermally conductive structure defining means for effectively connecting the heat dissipator in electrically and terminally conductive relationship between a connector and a terminal and means for effectively dissipating heat. The means for dissipating heat includes two spaced-apart electrically conductive supporting members defining an air space between them and a plurality of spaced-apart thermally conductive dissipator members mounted on and between the supporting members in thermally conductive relationship therewith. The dissipator members conduct heat from the supporting members and dissipate at least a portion of the heat thus conducted into the air space. In a particular embodiment the spaced-apart supporting members are leg portions of a bifurcated metallic member which also includes a bight portion integral with the leg portions and the leg portions are the means for effectively connecting the dissipator to a terminal.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
198 words
A three-pole electrical circuit breaker comprising: a. a molded casing having a pair of opposite wall portions; b. three terminal straps, one for a center pole and one for each of two outer poles of the circuit breaker, projecting outwardly of the casing and respectively having outer end portions disposed adjacent one of the opposite wall portions; c. three terminal straps, one for the center pole and one for each of the two outer poles of the circuit breaker, projecting outwardly of the casing and respectively having outer end portions disposed adjacent an other of the opposite wall portions; and d. six circuit breaker terminal connector and heat dissipator assemblies electrically and mechanically connected respectively to the outer end portions of the terminal straps, each of said assemblies including an electrically conductive generally U-shaped member having a bight portion connected to its respective terminal strap and a pair of spaced leg portions, a plurality of heat dissipator plates mounted between the leg-portions in spaced relationship to each other and in heat conductive relationship with the leg portions, and electrical cable connecting means secured to the generally U-shaped member on an outer side of one of the leg portions.
Claim 2
Dependent Claim
198 words
A three-pole electrical circuit breaker comprising: a. a molded casing having a pair of opposite wall portions; b. three terminal straps, one for a center pole and one for each of two outer poles of the circuit breaker, projecting outwardly of the casing and respectively having outer end portions disposed adjacent one of the opposite wall portions; c. three terminal straps, one for the center pole and one for each of the two outer poles of the circuit breaker, projecting outwardly of the casing and respectively having outer end portions disposed adjacent an other of the opposite wall portions; and d. six circuit breaker terminal connector and heat dissipator assemblies electrically and mechanically connected respectively to the outer end portions of the terminal straps, each of said assemblies including an electrically conductive generally U-shaped member having a bight portion connected to its respective terminal strap and a pair of spaced leg portions, a plurality of heat dissipator plates mounted between the leg-portions in spaced relationship to each other and in heat conductive relationship with the leg portions, and electrical cable connecting means secured to the generally U-shaped member on an outer side of one of the leg portions.
Claim 3
Dependent Claim
30 words
A circuit breaker as claimed in claim 1 wherein each of the leg portions of the generally U-shaped member has electrical cable connecting means secured to an outer side thereof.
Claim 4
Dependent Claim
92 words
A circuit breaker as claimed in claim 1 including four bus bars each connected adjacent one end to a respective terminal strap of one of the outer poles and having a respective one of the terminal connector and heat dissipator assemblies secured thereto adjacent an opposite end, the bus bars spacing the respective terminal connector and heat dissipator assemblies away from the center pole whereby the three terminal connector and heat dissipator assemblies adjacent each of the opposite wall portions of the casing are spaced farther apart than the respective terminal straps.
Claim 5
Dependent Claim
74 words
A circuit breaker terminal connector and heat dissipator assembly comprising an electrically conductive generally U-shaped member having a bight portion and a pair of spaced leg portions, a plurality of heat dissipator plates mounted between the leg portions in spaced relationship to each other and in heat conductive relationship with the leg portions, and electrical cable connecting means secured to the generally U-shaped member on an outer side of one of the leg portions.
Claim 6
Dependent Claim
74 words
A circuit breaker terminal connector and heat dissipator assembly comprising an electrically conductive generally U-shaped member having a bight portion and a pair of spaced leg portions, a plurality of heat dissipator plates mounted between the leg portions in spaced relationship to each other and in heat conductive relationship with the leg portions, and electrical cable connecting means secured to the generally U-shaped member on an outer side of one of the leg portions.
