Abstract

The circuit breaking device includes a main contactor section capable of switching connection and disconnection of a battery and a circuit, and a circuit breaker (10a) capable of cutting off the battery. A circuit breaker (10a) includes a connector connecting portion (41b) having a pair of connector circuit terminals (41bp, 41bn) related to energization of the coil of the main contactor portion, and a connector (43) for connecting The connector connecting portion (41b) is detachable, and has a connector short-circuit terminal (43a) for short-circuiting a pair of connector circuit terminals (41bp, 41bn) when assembled to the connector connecting portion (41b); and a claw portion (44a) , which restricts the fitting of the connector (43) relative to the connector connecting portion (41b).

Description

technical field [0001] The invention relates to a circuit breaking device. [0002] this application claims priority based on Japanese Patent Application No. 2013-027081 for which it applied on February 14, 2013, and uses the content here. Background technique [0003] Conventionally, there is known a control device that includes: a relay that can switch between connecting and disconnecting a power circuit and an electric load; a plug (safety plug, service plug) that can cut off the power circuit; The connection and disconnection are switched by attachment and detachment, wherein the control device controls the opening and closing of the relay according to the opening and closing of the contacts (for example, refer to Patent Documents 1 and 2). [0004] prior art literature [0005] patent documents [0006] Patent Document 1: Japanese Patent No. 3640682 [0007] Patent Document 2: Japanese Patent Laid-Open No. 2011-88598 [0008] Summary of the invention [0009] The ...
