検出装置。 A coil inserted into an electric circuit, a plunger inserted into the coil so as to be movable back and forth, a pair of horizontal pieces sandwiching the coil in the direction of movement of the plunger, and a pair of horizontal pieces that are substantially parallel to the direction of movement of the plunger and extending between the two side pieces. The yoke includes at least a magnetically bridging vertical piece, a return spring that urges the plunger to protrude from the coil, and a flexible connection line that connects the coil to an external circuit. The plunger is inserted into one horizontal piece of the yoke so that it can move forward and backward, and the spring force of the return spring is set so that when a short-circuit current passes through the electrical circuit, the plunger is drawn into the coil by the magnetic force of the coil. A storage space is formed on both sides of the plunger at a portion surrounded by both horizontal pieces, through which the connection wire can be inserted, and an insulating coating is formed on at least the portion of the connection wire that is inserted into the storage space. Current detection device.
