Title:
CIRCUIT STRUCTURE AND ELECTRICAL JUNCTION BOX
Document Type and Number:
WIPO Patent Application WO/2017/038419
Kind Code:
A1
Abstract:
This circuit structure (10) is provided with a circuit board (20) that has an opening (21) for connection. An electronic component 30 is mounted on the front surface of the circuit board (20); a plurality of bus bars (50) are arranged on the back surface of the circuit board (20); the electronic component has a plurality of connection terminals; and at least one connection terminal (33, 34) among the plurality of connection terminals is connected to a bus bar on the back surface of the circuit board through the opening 21 for connection. This circuit structure (10) is provided with: a heat dissipation member (90) which is provided on surfaces of the plurality of bus bars, said surfaces being on the reverse side of the surfaces to which the electronic component is connected, with an insulating heat-transfer member (80) that has electrical insulation properties and heat transfer properties being interposed therebetween; and a regulatory member (60, 70) which is provided between the plurality of bus bars (50) and the heat dissipation member (90), and which regulates movement of the insulating heat-transfer member (80) associated with temperature rise.
