Abstract
Abstract A circuit molded structure in which a crack is prevented from developing when a secondary molded member is integrally molded on a primary molded member having bus bars. The circuit molded structure includes the primary molded member (40) having a plurality of bus bars (42) insert-molded therein, and the secondary molded member (30) formed integrally on the primary molded member (40) by secondarily molding a resin on those portions of the primary molded member (40) other than terminal portions of the bus bars (42), the plurality of bus bars (42) forming internal circuits. Bent portions (45) of the bus bars (42) are exposed, and the secondary molding is effected with the exposed bent portions (45) covered with a resin spacer (47). As a result of the provision of the resin spacer (47), the resin will not flow to the bent portions, and the thickness becomes uniform, and any crack due to expansion and shrinkage will not occur.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
80 words
A circuit molded structure, comprising: a primary molded member including a plurality of bus bars insert-molded therein, said plurality of bus bars having terminal portions and exposed portions which are exposed from said primary molded member; a resin spacer attached to said exposed portions of said bus bars to cover said exposed portions; and a secondary molded member molded integrally on said primary molded member to cover said resin spacer, wherein said secondary molded member completely covers said resin spacer.
Claim 2
Dependent Claim
80 words
A circuit molded structure, comprising: a primary molded member including a plurality of bus bars insert-molded therein, said plurality of bus bars having terminal portions and exposed portions which are exposed from said primary molded member; a resin spacer attached to said exposed portions of said bus bars to cover said exposed portions; and a secondary molded member molded integrally on said primary molded member to cover said resin spacer, wherein said secondary molded member completely covers said resin spacer.
Claim 3
Dependent Claim
38 words
The circuit molded structure of claim 1, wherein said bus bars are respectively bent to form bent portions, and wherein said exposed portions of said bus bars are provided at said bent portions of said bus bars, respectively.
Claim 4
Dependent Claim
57 words
The circuit molded structure of claim 1, wherein said primary molded member and said secondary molded member are formed of a resin containing glass fibers, and wherein a direction of orientation of said glass fibers in said primary molded member is the same as a direction of orientation of said glass fibers in said secondary molded member.
Claim 5
Dependent Claim
57 words
The circuit molded structure of claim 2, wherein said primary molded member and said secondary molded member are formed of a resin containing glass fibers, and wherein a direction of orientation of said glass fibers in said primary molded member is the same as a direction of orientation of said glass fibers in said secondary molded member.
Claim 6
Dependent Claim
14 words
