Problems solved by technology

Therefore, when the attaching and detaching operations of the second housing with respect to the first housing are repeated, the surface of the contact portion where the female terminal and the male terminal slide with each other may be scratched.
In addition, by applying plating on the surface of the scratched terminal, the base is exposed, causing the exposed part to be oxidized and the resistance to increase
As a result, connection reliability may decrease

Abstract

In a power circuit disconnecting device, a connector includes a first connector housing and a second connector housing, and the first terminal and the second terminal are arranged on the first connector housing and the second connector housing. In the body, the second terminal includes contact pieces with a gap therebetween that is larger than the width dimension of the first terminal. The second connector housing includes a pressure plate portion. The second terminal is accommodated between the pressure plate parts, the second terminal is movable between a first position and a second position, when the second terminal is in the first position, a part of the contact piece extends beyond the distal end of the pressure plate part, when When the second terminal is at the second position, a part of the contact piece is completely retracted into the space between the pressing plate parts. The contact piece is pushed such that the contact piece contacts the terminal board portion.

Description

technical field [0001] The invention relates to a connector and a power circuit cutting device. Background technique [0002] In a vehicle such as an electric car or a hybrid car, in order to ensure work safety during maintenance of an electric system or the like, a power circuit cutoff device called a service plug is provided, which cuts off conductivity between a power source and a load. [0003] A prior art power circuit cutoff device includes a first case mountable to the first case and a second case detachable from the first case. The female terminal provided in the first housing and the male terminal provided in the second housing function as a power switch (for example, see JP2012-243559A and JP2013-062043A). In the power circuit disconnecting device, the power switch is turned on or off by attaching or detaching the second housing to or from the first housing so that the male terminal is inserted into or removed from the female terminal. [0004] In the above power...
