Document Type and Number:
WIPO Patent Application WO/2018/088275
Kind Code:
A1
Abstract:
Provided is an electrical junction box with which it is possible to prevent, in advance, a switching element from igniting. The electrical junction box (1) according to an embodiment of the present invention is provided with a circuit substrate (31) having switching elements (32) mounted on one surface thereof, and an accommodating body (2) that accommodates the circuit substrate (31), wherein a thermally expanding expansion member (41) is also accommodated in the accommodating body (2). When the temperature of the switching elements (32) is low, the expansion member (41) is placed opposite the one surface and is set apart from the circuit substrate (31) and the switching elements (32). When the temperature of the switching elements (32) is high, the switching elements (32) become embedded in the thermally expanded expansion member (41).
