ON/OFF DETECTION TYPE BLOCK INTERRUPTER SWITCH

Abstract

The present invention provides a conduction / disconnection detection type blocking piece cut-off switch capable of effectively removing foreign objects at a contact part. Equipped with: a frame-shaped housing; a slider insertion port provided on the upper surface of the housing; a support part provided on the inner side of the housing; a fixed terminal having a cutout at one end of the rectangular shape to fix the other end On the inner surface of the housing; a rectangular movable terminal, one part of which is fixed to the supporting part; a slider, which has a slider insertion hole penetrating the housing and a cutout of the fixed terminal protruding into the housing, and is positioned downwards. The terminal press-in part that pushes down the end of the movable terminal when pressed; the spring that urges the slider upward; the hook-shaped bent part that is located at the cutout part of the fixed terminal and the free end side of the movable terminal When the slider is not pressed down, the inclined surface of the curved part of the fixed terminal and the movable terminal is used as the contact surface. The fixed terminal and the movable terminal are in contact with each other in a way that can conduct current. When the slider is pressed When pressed, the fixed terminal and the movable terminal are separated and insulated.

Description

technical field [0001] The invention relates to a blockage cut-off switch for detecting the disassembly and assembly of a tongue-shaped plate arranged on a safety belt to a buckle body. Background technique [0002] Seat belt devices are attached to seats of automobiles and the like in order to protect occupants in emergency situations such as collisions. In order to easily attach and detach such a seat belt device, a buckle device is provided on a seat of an automobile or the like. The buckle device spring-biases a latch member that latches the tongue plate in a latching direction, and at the same time maintains the latch member in a latched state of the tongue plate and the buckle body by a locking member. In this kind of buckle device, it is necessary to display the latched state of the tongue plate and the buckle body through the lamp, or to control the operation of the seat belt take-up force reduction mechanism, or to provide airbag ECU (Electronic Control Unit) Send...
