Problems solved by technology

[0005] On the other hand, when the connectors of the power circuit are joined, there is no problem of arcing like when the connectors are separated, but since the inrush current flows due to the load when connecting the connection terminals, the connectors of the power circuit Terminals may be damaged

Embodiment Construction

[0027] The power cutoff device described in Patent Document 1 can also be further miniaturized. That is, since the fitting detection receiving connector is provided along the outer side of the side surface in the longitudinal direction of the case accommodating the receiving connector, and fitting to the fitting detection of the fitting detecting receiving connector The plug connector is provided at one side of the operation lever, so the width of the power cutoff device in the lateral direction increases. In the power cutoff device described in Patent Document 1, no waterproof structure is considered.

[0028] Therefore, an advantageous aspect of the present invention is to miniaturize a connector type power cutoff device installed between a power source and a load.

[0029] refer to Figures 1 to 11D One embodiment of the connector type power cutoff device of the present invention is described as follows. Such as figure 1 As shown in , the power cutoff device 1 of this e...

Abstract

In a power shutoff device, an operation lever is provided to be rotatable between a first position where a receiving connector and the plug connector are separated and a second position where the receiving connector and the plug connector are fitted. The operation lever is slidable in a direction perpendicular to the fitting direction at the second position. A fitting detecting connector includes a fitting detecting receiving connector accommodating a pair of fitting detecting terminals in a pipe body penetrating and protruding from a side wall of a housing of the receiving connector, and a fitting detecting plug connector accommodating a conductive member electrically connecting the fitting detecting terminals in a pipe body. The fitting detecting plug connector is provided at a distal end part of the operation lever so as to be fitted to the fitting detecting receiving connector when the operation lever slides at the second position.

Description

technical field [0001] The present invention relates to a power cutoff device, in particular to a connector type power cutoff device installed between a power source and a load. Background technique [0002] Generally, if a power supply circuit that supplies power to a load includes a connector, by separating the connector, the load can be separated from the power supply so that the load can be inspected or maintained safely. However, when the power is cut off by disconnecting the connectors, an arc is generated between the connector terminals of the separated plug connector and receiver connector due to the load, thereby damaging the connector terminals and the like. Therefore, in the operation of separating the mated connectors, two steps including time lag are performed. That is, there is proposed a power cutoff device for detecting an action of switching a connector from a mated state to a disengaged state, opening a relay contact mounted in a power supply circuit by a ...
