[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a through-type terminal board whose screw is highly reliable, lightweight, and solid.

[0002]

2. Description of the Related Art A conventionally known through-type terminal board has a C-shaped energizing plate 10 penetrating vertically between a partition plate 2 of an insulating base 1 as shown in FIG. Horizontal piece 10
Screws 3 and 3 are screwed into a and 10b, and the upper and lower horizontal pieces 10a and 10b are burred. As another example, as shown in FIG. 7, a brass rod 15 is buried in place of the C-shaped current-carrying plate 10 shown in FIG.
5 is screwed with screws 3 and 3.

[0003]

When the conventional C-type current-carrying plate is used, cracks easily occur on the outer periphery of the burring, the reliability of screw accuracy is low, and the number of threads is small. There was a problem .

When the brass rod is used, the reliability of the screw is high, but it is relatively expensive and heavy.

[0005]

However, this invention solves the above-mentioned conventional problems by using a U-shaped current-carrying plate and embedding the nut in a synthetic resin cylinder .

That is, according to this invention, a U-shaped current-carrying plate is set in each partition by the upper and lower partition plates of the insulating base, and screw holes are provided in the upper and lower lateral pieces of the current-carrying plate, and the screw holes are provided inside thereof. The penetration type terminal board is characterized in that a nut to be screwed with a screw to be inserted is installed.

In another invention, the current-carrying plate is a brass plate, and the nut is fixed by a synthetic resin cylinder. The nut is embedded in the synthetic resin cylinder and fixed inside the U-shaped or C-shaped current-carrying plate. It is a thing.

Another invention is characterized in that a U-shaped current-carrying plate set having screws and nuts is fitted in a vertical groove portion of an insulating single body, and an insulating cover is fitted and fixed to the insulating single body. It is a through-type terminal board, and a U-shaped current-carrying plate in which screws and nuts are set in the vertical groove portion of the insulation unit is fitted, and the insulation unit is unevenly fitted and fixed to the insulation unit to form the terminal unit unit. The through-type terminal board is characterized in that a plurality of the terminal board units are fastened and fixed by a common assembly bolt and a nut screwed to the same.

The screw holes described above are merely circular holes and have no screw.

Since the nut is arranged for tightening and fixing the terminal in cooperation with the screw, it is not limited to the fixing structure or the facing arrangement structure with the U-shaped current-carrying plate.

[0011]

According to this invention, the screw is screwed on the U-shaped or C-shaped current-carrying plate with the nut, so that the nut is lightweight and the tightening is reliable, the reliability of the screw is high, and the nut is cracked when tightened. There is no fear. In addition, conventional products are used for burring
Although cracks may occur, this
Since no ring is used, there is no fear of this.

[0012]

Embodiment 1 An embodiment of the present invention will be described with reference to the drawings.

Partition plates 2 and 2 are provided above and below the insulating base 1 at predetermined intervals, and U-shaped current-carrying plates 4 are embedded in the partitions 5 and 5 formed by the partition plates 2 and 2, respectively. Screw holes 6 are provided in the upper and lower horizontal pieces 4a, 4b of the current -carrying plate 4, and nuts 7, 7 for screwing the screws 3, 3 are fixed inside the screw holes 6.

The nuts 7, 7 are fixed by an insulating cylinder 8.

Although the U-shaped current-carrying plate 4 is used in the above embodiment,
The same applies to a C type instead of the U shape. In the figure, 9 is a washer, 11 is a transparent cover, 12 is a cover fixing screw, 13
Is a connecting bolt.

The insulating tube 8 in the embodiment, for example, vinyl resin or <br/> and polybutylene terephthalate tallates made, used to reliably set the nut.

In this embodiment, as is usual, the terminal 14 is interposed between the washers 9 and tightened and fixed, but since a nut is built in, the reliability of the screw is high,
Even if the tightening force increases, there is no risk of cracks.

[0018]

Second Embodiment Another embodiment will be described with reference to FIG.

An energization plate set 18 in which a screw 3, a nut 7 (same as in FIG. 1), a U-shaped energization plate 4 and an insulating tube 8 are assembled is fitted into a vertical groove 17 of an insulating base 16 as a unit (upper and lower stages). Part 1
9 and 19, the end edge of the current-carrying plate 4 is fixed), and the projection 22 of the insulating cover plate 20 is fitted and fixed in the assembly hole 21 of the insulating base 16 to form the unit terminal board 23. In the figure, 2 is a partition plate.

If a plurality of the unit terminal boards 23 are sequentially brought into contact with each other in parallel and tightened and fixed by the common bolts 13 and nuts 24, a terminal board having a large number of poles can be easily assembled.

[0021]

[Effects of the Invention] This invention is designed above and below a U-shaped or C-shaped energizing plate.
A screw hole is provided in the horizontal piece, and a nut embedded in the insulating cylinder
Since it has been exposed to electricity, it has sufficient strength to ensure electricity
Together, without the need for burring and thread roots Ji Shin <br/> Yoriyukido is large, and there are various effects such as risk Gana had to occurrence of cracks. Also, the nuts are embedded above and below the insulation tube.
Position accuracy and strength and can be securely tightened
There is also an effect. In addition, by making it possible to assemble , there is an effect that even a complicated structure can be manufactured relatively easily and easily.
Is also easy.

When the present invention has an assembled structure, it has an effect that a complicated structure can be easily constructed.
