Abstract
A bus bar module (10) includes a bus bar (11) made of a metal material integrally molded into an insulating layer (12) made from resin. The bus bar module (10) also includes a distortion absorptive section (15) for absorbing distortion resulting from difference in the thermal expansion coefficient between the bus bar (11) and the insulating layer (12). Thus, the insulating layer (12) can stretch out by a difference in expanded dimension between the insulating layer (12) and the bus bar (11) at thermal expansion. In this way, the distortion resulting from the difference in the thermal expansion coefficient between the bus bar (11) and the insulating layer (12) can be absorbed, and crack occurrence in the insulating layer (12) can be prevented.
Claims2
A bus bar module comprising an elongate bus bar made of a conductive metallic material and having opposite first and second ends;
- and a resin insulating layer integrally molded around the bus bar, whereby
- the resin insulating layer comprises a first section extending from a location in proximity to the first end of the elongate bus bar to a location between the first and second ends of the elongate bus bar, the resin insulating layer further comprising a second section extending from a location in proximity to the second end of the elongate bus bar to a location in proximity to the first section of the resin insulating layer, a distortion absorptive gap being provided between the first and second sections of the resin insulating layer for allowing a distortion to be absorbed that results from a difference in thermal expansion coefficients between the bus bar and the insulating layer.
