Here, for example, when the short-circuit terminal is separated from the circuit terminal in the current conducting state to interrupt the energization, an arc is generated between the short-circuit terminal and the circuit terminal in the semi-fitted state, and if this arc generation continues for a long time, For example, excessive heat generation may occur. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a service plug capable of extinguishing an arc when power is cut off in a short time.

When the members are brought into contact with each other and the connection electrodes are electrically short-circuited, the second elastic member is set to be elastically compressed. Furthermore, when the contact portion of the first case is brought into contact with the second case body, the first elastic member is set to be elastically compressed, and the first engaging portion and the second engaging portion are To fix the first and second cases.
Here, when the engagement state between the first engaging portion and the second engaging portion is released, the restoring force of the first and second elastic members causes the first
The force acts in the direction in which the case and the second case are separated from each other, and in the direction in which the connection electrode and the short-circuit member are separated from each other. As a result, for example, compared to a case where the first case and the second case are separated only by hand, the connection electrode and the short-circuit member can be separated to a distance at which the arc can be extinguished in a shorter time, and the energization can be performed. It is possible to prevent the arc from being generated between the connection electrode and the short-circuit member for a long time when the circuit is cut off.

Then, when the second case is further inserted, the first elastic member between the contact portion and the first case main body (for example, the bottom surface in the first case) is elastically compressed, and The short-circuit member of the second case contacts the pair of connection electrodes of the first case. When the second case is further inserted, the second elastic member between the second case main body (for example, the bottom surface in the second case) and the short-circuit member is elastically compressed, and in this state, the first engaging member is engaged. The first and second cases are fixed by engaging the mating portion and the second engaging portion. From this fixed state,
When the engagement state between the first engagement portion and the second engagement portion is released, the first engagement portion is released.
Also, the second case can be pulled up from the inside of the first case by the restoring force of the second elastic member. That is, for example, as compared with a case where the first case and the second case are separated only by hand, the connection electrode and the short-circuit member can be separated to a distance where the arc can be extinguished in a shorter time, and the current can be cut off. Occasionally, it is possible to prevent the arc from being generated between the connection electrode and the short-circuit member for a long time.

The opening end 14A of No. 4 is brought into contact with the contact member 24 of the first case 12, and the second case 14 is pushed downward in the vertical direction. As a result, the first spring 23 that supports the contact member 24 is compressed and contracted into an elastically deformed state, and a restoring force that moves upward against the force of the operator or the like pushing the second case 14 downward is generated. Then, as shown in FIG. 6, as the second case 14 moves downward in the vertical direction, the claw portion 34 of the lever 33 causes the protrusion 2 of the first case 12 to move.
5, the claw portion 34 further rides over the protruding portion 25, and the lever 33 elastically deforms in the horizontal direction. At this time, the short-circuit electrode portions 32, 32 of the short-circuit member 13 of the second case 14 are connected to the connection electrodes 11, 1 of the first case 12.
It contacts with each electrode part 21 and 21 of No. 1. As a result, the pair of connection electrodes 11, 11 are electrically short-circuited, and the second spring 31 supporting the short-circuit member 13 is compressed, so that the operator or the like pushes the second case 14 downward. Repulsive upward elastic force is generated.
