It can be used as a short circuit plate (20C) for connecting wiring. Hereinafter, an example of this embodiment will be described.

  The length of the short-circuit plate 20 (FIG. 1) in the longitudinal direction is manufactured in advance with a predetermined length corresponding to the width of the terminal block 30 (for example, FIG. 1) to be short-circuited (length corresponding to the terminal arrangement direction).

Even in such a case, the operator can make the short-circuit plate 20A manufactured at a predetermined length in response to the work site to be longer than the interval between the two terminal blocks 30A and 30B to be installed. It can be used by cutting according to the dimensions. It is assumed that, by this cutting, for example, a cut short circuit board (hereinafter, referred to as a short circuit board for connecting wiring) 20C is obtained.

  When connecting the short-circuit plate 20A attached to the terminal block 30A and the short-circuit plate 20B attached to the terminal block 30B using the short-circuit plate 20C for cross-wiring, the following work is performed as a crossover wiring.

  The wiring wiring short-circuit plate 20C is screwed at least at the following two locations by a stopper plate 52 formed of a flat plate provided with the stopper 50 and a through hole.

  The plane of the plate-like portion 22C and the plane of the plate-like portion 22A are aligned so that the cutout 21C of the short-circuit board 20C for crossover and the cutout 21A on one side of the crossover boards 20A and 20B overlap.

Screw together with the other plane.

  As a result, the short-circuit plates 20A and 20B can be electrically conducted by the short-circuit plate 20C for crossover wiring used as the crossover wiring.

  As explained above, it is only necessary to cut the manufactured shorting plate to the necessary length for crossover wiring without arranging many kinds of shorting plate lengths. Can be used to connect the short-circuit wiring in the terminal block.

  According to 2nd Embodiment, according to the pitch between the terminals of a terminal block, a short circuit wiring can be attached in arbitrary positions. Furthermore, the short-circuit wiring in the plurality of terminal blocks can be easily connected.

After crimping the short-circuit plate 70e, the flat terminal portion 92 is a portion that is sandwiched between the plate-like portion 71e and the plate-like portion 72e.

  The flat terminal portion 92 and the sandwiching portion 93 are connected by a metal fitting connecting portion 95. The metal fitting connecting portion 95 is formed by being bent into a Z shape at a right angle. Thereby, even if the short-circuit plate 70e and the short-circuit plate 70f are arranged side by side in the vertical direction as shown in FIG. 15, the short-circuit plate 70e and the short-circuit plate 70f are crimped to the necessary terminals of the terminal block 30e. The terminal insertion fitting 90 can be attached.

  The protruding portion 91, the flat terminal portion 92, the sandwiching portion 93, and the metal fitting connecting portion 95 as described above can be electrically connected.

  Below, an example of the working method with the short circuit wiring of the short circuit board 70f shown in FIG. 15 and the short circuit wiring of the short circuit board 70e is demonstrated.

  First, the protrusion 91 of the terminal insertion fitting 90 is aligned with the groove 73e of the short-circuit plate 70e, and the flat terminal portion 92 is slid from the lateral direction along the longitudinal direction between the plate-like portion 71e and the plate-like portion 72e. insert. As shown in FIG. 15, all the inserted terminal insertion fittings 90 are moved along the groove 73e to the terminal position of the terminal block 30e that needs to be short-circuited. The terminal block 30e is temporarily fixed to a terminal that needs to be short-circuited, and the necessary portion of the short-circuit plate 70e is crimped. After crimping, the temporary fixing is removed and the short-circuit plate 70e is removed.

  Next, the protrusion 91 of the terminal insertion fitting 90 is aligned with the groove 73f of the short-circuit plate 70f, and the flat terminal portion 92 is slid from the lateral direction along the longitudinal direction between the plate-like portion 71f and the plate-like portion 72f. Insert into. As shown in FIG. 15, all the inserted terminal insertion fittings 90 are moved along the groove 73f to the terminal position of the terminal block 30e that needs to be short-circuited. The terminal block 30e is screwed to a terminal that needs to be short-circuited, and the necessary portion of the short-circuit plate 70f is crimped.

  Next, the removed short-circuit plate 70e is screwed to the terminal block 30e. At this time, an insulating sheet such as an electrically insulating resin is pasted between the short-circuit plate 70e and the short-circuit plate 70f. Thereby, the short circuit board 70e and the short circuit board 70f can be insulated, and two systems of short circuit wiring can be given to the one terminal block 30e.

  According to the fifth embodiment, the short-circuit wiring can be attached at an arbitrary position according to the pitch between the terminals of the terminal block. Further, two systems of short-circuit wiring can be easily applied to one terminal block.
