  However, according to the above-described conventional technology, the distance between the terminals of the watt hour meter varies, and the power failure device cannot be connected to various watt hour meters, and it is necessary to prepare a power failure device according to each distance. It was.

  In addition, the work of installing one power failure device for each pole was complicated, and it was disjointed and the fit was bad. Also, the switch had to be switched on and off.

  Therefore, the present invention has an object to provide a connection structure for a power failure device that can be connected to various watt-hour meters having a simple structure and different distances between terminals. The number of conductive bars corresponding to the number is protruded, and at least one of the conductive bars is movable from the main body of the power failure device, and is movable according to the distance between the terminals of the watt-hour meter. Features.

  The connection structure of the power failure device according to the present invention has a number of conductive bars corresponding to the number of poles protruding from the main body of the power failure device, and at least one of the conductive bars is movable at a position protruding from the main body of the power failure device. In order to be able to move according to the distance between the terminals of the watt hour meter, the distance between the terminals of the different watt hour meters can be handled by the same power failure device, and can be connected to various watt hour meters.

  The purpose of making it possible to attach to various types of watt-hour meters with different distances between terminals was provided with a simple structure without compromising the ease of connection work.

  The connection structure of the power failure apparatus according to the present invention will be described with reference to the accompanying drawings of FIGS.

  A power failure device 1 for stopping the supply of electricity, which is connected to a watt hour meter 2 and cuts off an electric circuit. A switch 4 for connecting or disconnecting the electric circuit is provided in the approximate center of the main body 3 of the power failure apparatus 1. From the main body 3 of the power failure device 1, the number of conductive bars 5 connected to the watt hour meter 2 is made to correspond to the number of poles.

  FIG. 2 shows a tripolar power failure device. The conductive bars 5a, 5b, and 5c connected to the X pole, N pole, and Y pole are projected. The N-pole conductive bar 5 b is fixed to the main body 3. The X-pole and Y-pole conductive bars 5 a and 5 c are substantially bar-shaped conductive bars provided with a fixed piece 6 inside the main body 3 and connected to the fixed piece 6 via an electric wire 7.

  A long groove 8 is provided on the side surface of the main body 3, and the X and Y conductive bars 5 a and 5 c are movable within the long groove 8. Further, the ends of the conductive bars 5a and 5c on the side accommodated in the main body 3 are bent so that the conductive bars 5a and 5c do not come out of the long groove 8.

  The structure and dimensions of the watt-hour meter 2 are various, and the distance between the terminals 9 is also different. The N pole conductive bar 5 b is connected to the terminal 9 of the watt hour meter 2, and the X pole and Y pole conductive bars 5 a and 5 c are moved and connected to the terminal 9 of the watt hour meter 2.

  FIG. 4 shows a power failure apparatus 10 provided with a movable conductive bar. A groove 12 and a long groove 13 are formed on the side surface of the main body 11, a conductive bar 14 a is projected from the groove 12 and fixed to the main body 11, and a conductive bar 14 b is movably provided in the long groove 13.

  FIG. 5 shows a power failure device 15 provided with two movable conductive bars. Two long grooves 17 are formed on the side surface of the main body 16, and the conductive bars 18 project from the two long grooves 17. The conductive bars 18 are movable within the long grooves 17.

  Since the conductive bar protruding from the power failure device main body is movably provided, it can be used for terminals of various watt-hour meters. It can be applied to various electricity meters with the same power outage.
