Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an improvement of a terminal board used in a terminal block and provided with a plurality of wire connection parts.

(Prior Art) As shown in FIGS. 4 and 5, a conventional terminal board with a plurality of wire connection parts has an upper plate part 21 and a lower plate part 22 arranged vertically to facilitate wiring. A device connected by a plate portion 23 is known. However, in such a terminal board, if the electric wires 24 connected to the upper plate part 21 and the electric wires 25 connected to the lower plate part 22 overlap, the electric wires on the lower plate part 22 side will be hidden, making maintenance inspection impossible. Since the wiring work becomes difficult, it is necessary to shift the upper and lower electric wires 24 and 25 as shown in the figure so that the wiring can be done, resulting in the problem that the width of the entire terminal board becomes wider.

(Problems to be solved by the invention) The present invention solves the above-mentioned conventional problems and makes the overall width narrower than the conventional one even when a large number of wire connections are provided. It was completed with the aim of creating a terminal board that can be used to easily connect the wires underneath and facilitate maintenance and inspection work.

(Means for Solving the Problems) The present invention has an upper plate portion provided with a wire connection portion and a lower plate portion similarly provided with a wire connection portion, with the upper plate portion facing the distal end and the lower plate portion facing the proximal end. In addition, a space is provided between the two for the insertion of electric wires, and the two are connected in a step-like manner by a connecting plate on the side.

(Example) Next, the present invention will be explained in detail with reference to the illustrated embodiments. 1 is an upper plate portion provided with a plurality of wire connection portions 2, and 3 is a lower plate portion similarly provided with a plurality of wire connection portions 4. It is. This lower plate portion 3 is the base end side of the entire terminal board, and has a base end terminal attachment portion 5 for outputting current to each wire connection portion 2, 4.
The upper plate part 1 on the distal end side and the lower plate part 3 on the proximal end side are connected in a step-like manner by the side connecting plate parts 7, with a space 6 for the insertion of electric wires provided between them. connected together. As is clear from FIG. 2, in this embodiment, the wire connection portion 2 of the upper plate portion 1 and the wire connection portion 4 of the lower plate portion 3 are located at positions where the upper and lower electric wires 8 and 9 connected to each other overlap. Furthermore, the width between the wire connecting portions 2 and 4 can be minimized within the range necessary for connecting the wires 8 and 8 and the wires 9 and 9. Note that it is convenient to insert the electric wire 9 through the space 6 if the connecting plate part 7 is provided only on one side and the space 6 is open at one end, but the connecting plate part 7 may be formed on both sides. Needless to say.

(Function) The device configured in this way is shown in Figures 2 and 3.
As shown in the figure, the whole body is attached to the base 10, and the electric wire 9
The lower plate part 3 on the proximal end side through the space 6 for inserting the electric wire.
At the same time, the electric wire 8 is attached to the electric wire connecting part 4 formed in the upper plate part 1 on the distal end side, and the bus bar 1 is attached to the proximal terminal attaching part 5 of the lower plate part 3.
1 is attached and used. In this way, in the present invention, the wire attachment part 4 of the lower plate part 3 to which the lower electric wire 9 is connected is always exposed, so even if the electric wires 8 and 9 are overlapped one above the other, wiring work and maintenance inspection can be carried out easily. It does not cause any hindrance to the work. Therefore, the distance between the wire connection parts 2 and 2 and the distance between the wire connection parts 4 and 4 can be minimized by ignoring the vertical overlap and considering only the lateral relationship, so that the distance between the wire connection parts 2 and 4 can be minimized by considering only the lateral relationship. The width can be made much narrower than the conventional one. Moreover, since the upper plate part 1 and the lower plate part 3 are integrated with the connecting plate part 7 on the side, the electric wire 9 wired to the lower plate part 3 can be routed through the lower surface of the upper plate part 1 by the shortest distance. can pass through, making wiring work easy. In addition, although the structure according to the embodiment has two upper and lower stages, it is of course possible to have three or more upper and lower stages.

(Effects of the invention) As is clear from the above explanation, this invention allows the width of the terminal board to be narrowed because all the wire connection parts are exposed even if the wires are stacked one on top of the other, and the width of the terminal board can be narrowed. Since the plate part is integrated with the connecting plate part on the side, the electric wires routed to the lower plate part can pass through the lower surface of the upper plate part in the shortest distance, making the wiring work easy. Therefore, the present invention has extremely great practical value as it solves the problems of conventional terminal boards of this type.
