Description

  The present invention relates to a terminal block device that can reliably connect a terminal block for wiring used in a control panel, a power distribution panel, and the like, in particular, between terminals of a two-stage stacking terminal block in a short time without being influenced by the level of an operator.

  Conventionally, among the wiring terminal blocks used for control panels, distribution boards, etc., when using a two-stage stacking terminal block with a small mounting space and excellent functionality, as shown in FIG. Since connecting wires with crimp terminals attached to both ends of the electric wire 3 are used to connect the upper and lower terminals of the stacked terminal block 1, work takes time. In addition, there are problems such as individual differences in the quality of wiring, such as different wire lengths depending on the person in charge of wiring.

  On the other hand, a Z-type metal fitting having a plurality of different terminal surfaces is attached to a terminal block that branches the input power source into a plurality of output power sources in a compact size, and an input terminal portion or A branch terminal block device provided with an output terminal portion is known (see, for example, Patent Document 1).

JP 2007-294333 A

  As described above, when connecting the upper and lower terminals of the two-stage stacked terminal block 1 using the connecting wires with the crimp terminals attached to both ends of the electric wire 3, it takes time. In addition, there are problems such as individual differences in the quality of wiring, such as different wire lengths depending on the person in charge of wiring.

  In addition, when the Z-type metal fittings described in Patent Document 1 are used, the above-described problems can be solved. However, the Z-type metal fittings have an insulation treatment like a jumper wire (electric wire). Since it is not applied, there is a problem that the safety during operation of the device is inferior to that of the crossover.

  The present invention solves the above-mentioned conventional problems, and it is not necessary to create a crossover wire with crimp terminals attached to both ends of the wire, and there is no individual difference in the quality of wiring, and the device is in operation. It is an object of the present invention to provide a terminal block device having safety equivalent to that of a conventional wiring with a crossover.

  In order to achieve the above object, a terminal block device according to the present invention comprises a two-stage stacked terminal block in which an upper stage surface on which an upper terminal is arranged and a lower stage surface on which a lower terminal is arranged are formed in a staircase shape. A terminal block wiring device comprising an electrically conductive member and having an upper bent portion, a lower bent portion, and an intermediate portion connecting the upper bent portion and the lower bent portion, The bent part faces the upper stage surface of the terminal block, the lower bent part of the terminal block wiring device is attached facing the lower stage surface of the terminal block, and insulation treatment is applied to the predetermined surface of the intermediate part of the terminal block wiring device. It is characterized by being an insulating part.

  According to the present invention, the upper and lower terminals can be reliably connected in a short time regardless of the level of the operator, and the safety during the operation of the device is equivalent to that in the case of wiring with a conventional crossover. Can be made.

The disassembled perspective view which shows the structure of the terminal block which concerns on one Embodiment of this invention. The perspective view which shows the structure of the terminal block which concerns on one Embodiment of this invention. The perspective view which shows the structure of a prior art example.

  Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is an exploded perspective view showing a configuration of a terminal block device according to an embodiment of the present invention. As shown in the figure, the terminal block device of this embodiment includes a terminal block 1 and a terminal block wiring device 2. FIG. 2 is a perspective view showing the configuration of the terminal block device of this embodiment in which the terminal block wiring device 2 is attached to the terminal block 1.

  The configuration of the terminal block device of this embodiment will be described with reference to FIGS. 1 and 2.

  The terminal block 1 is a two-stage stacked terminal block in which terminals are arranged vertically, and an upper step surface 11 on which an upper terminal is arranged and a lower step surface 12 on which a lower terminal is arranged are formed in a step shape.

  The terminal block wiring device 2 is for connecting the upper and lower terminals of the terminal block 1. For example, a rectangular metal plate is Z-shaped in accordance with the stepped shape of the upper step surface 11 and the lower step surface 12 of the terminal block 1. It is a Z-type terminal block wiring device which is created by bending in a shape and has an upper bent portion 21, a lower bent portion 22, and an intermediate portion 23 connecting these upper bent portion 21 and lower bent portion 22. .

  The upper bent portion 21 and the lower bent portion 22 are respectively provided with attachment holes, and are exposed when the front surface and at least one side surface of the intermediate portion 23, that is, the terminal block wiring device 2 is attached to the terminal block 1. Insulation treatment is applied to the surface to form an insulating portion.

  As shown in FIG. 2, when this terminal block wiring device 2 is attached to the terminal block 1, the upper bent portion 21 of the terminal block wiring device 2 faces the upper surface 11 of the terminal block 1, and the terminal block wiring device 2 The lower bent portion 22 is attached so as to face the lower step surface 12 of the terminal block 1. Thus, since the terminal block wiring device 2 has a shape that matches the stepped shape of the terminal arrangement of the two-tiered terminal block of the terminal block 1, there is no jump out of the electric wire as in the conventional case.

  As described above, it is not necessary to create a crossover with crimp terminals attached to both ends of the wire, and to prevent individual differences in the quality of wiring, and because it has a shape that takes into account the displacement of the upper and lower terminals, other wiring Can be provided. Furthermore, since an insulation process is performed on a predetermined surface (a surface exposed when the terminal block wiring device 2 is attached to the terminal block 1) of the intermediate portion 23 of the terminal block wiring device 2, the device is in operation. Safety can be made equivalent to the case of conventional wiring with crossovers.

  In addition, by coloring the insulation part and coloring it according to the type of terminal, for example, when using it for wiring of power supply etc., the polarity etc. can be judged visually, so accidents due to mistakes in polarity etc. It can also be prevented.
