Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a power supply terminal device used to supply power from an electrically conductive insulated wire.

When power company workers install measuring equipment to measure electric current, voltage, power, etc. in outdoor distribution* or green areas, they must
It is common for measuring instruments to receive power from live distribution lines.

Conventionally, the method of bringing in power to a measuring instrument is to strip the insulation coating of a live power distribution line (insulated wire) with a knife and apply a thin power supply wire to the bare core wire. Power is being supplied.

This conventional work method has the disadvantage that the knife hits the bare wire portion of the power distribution line, which exposes the worker to the risk of electric shock.

This invention was made in order to eliminate the drawbacks of the conventional method as described above, and provides a safe power supply terminal device that allows power to be input to a measuring instrument without touching the bare green power distribution line in the energized state. is intended to provide.

An embodiment of the present invention will be described below based on the drawings. 1st
In Figures to Figure 8, (1) is an insulating covering cloth in an energized state;
The figure shows a wicker and is composed of a core wire (la) and a covering (1b). (2i A part of the fd cover, which has a hollow cylindrical shape, and a female screw (8) is provided inside this cylinder. Furthermore, a push ball (4) protrudes from the center of the cover part (2). This push rod (4) is connected to the rotation hole (
5a), a press plate (6) is rotatably press-fitted into the tip thereof. In addition, there is a screw groove (7) on the top surface of the cover part (2), which can be loosened with a screw (8).
is installed. On the other hand, the other end of the mark-shaped connector (5) is pivotally connected to the base αQ by a pin (9). This base part a0 has a U-shaped electric wire insertion hole aυ in the center and a male screw part (2) on the outer periphery, and the above-mentioned U-shaped
A needle-like electrode (to) is installed on the bottom surface of the insertion hole Uυ, and is electrically connected to the lead wire θ wire. That is, there is a screw Q8 at one end of the acicular frost pole 4, and the lead length (
One crimp terminal ση is fixed. Further, the metal parts of the screw fm aQ z crimp terminal αη and the nut αG of this needle electrode are fixed to the base GO with a filler aQ such as epoxy and are insulated from the outside to eliminate the risk of electric shock. In addition, the above-mentioned type connection J1. (5) ld bin (9
) is the center of rotation and can rotate more than 90 degrees once.

Next, the operation will be explained. When attaching the power supply terminal device described in L to the distribution line, attach part of the cover (2) to the base part 0.
1, the shape of Figure 3 pμ), U of base & 110Q
After inserting the electric wire (1) into the letter-shaped electrical insurance insertion hole συ, remove part of the cover (
2) and the screws of the base part αq are engaged and tightened, and the needle lightning 1 pole σ3 of the base part Q (1) breaks through the sheathing (1b) of the visible electric wire (1) and hits the core wire (la), drawing in power. (state shown in Fig. 4) o By the way, in this case, the first force bar part (2) and the base part σO are female threads F!1
) and the male screw part (2) are fixed by the tongue,
If you use the threaded part for a long time, it may become loose due to wind and rain, temperature changes, vibrations, etc. Therefore, in order to prevent this loosening, some parts of the cover (2
) and the base part CG, then attach the locking screw (8) to the L-shaped connector (5) as shown in Figures 4 and 5.
) If you tighten it in a position that does not touch the cover, part of the cover (2)
When the is loosened and rotated, this thumbscrew (
8) is applied, resulting in a structure in which part of the cover does not loosen beyond a certain angle.

In the embodiment described in t, the power supply insertion hole is made U-shaped, but the effect is the same even if the bottom of this insertion hole is made V-shaped. Furthermore, although the explanation has been made with one sword-shaped electrode 03, reliability can be improved by installing a plurality of them.As described above, according to the present invention, the L-shaped connector can be used to connect part of the cover. Since the base parts are connected, part of the cover does not fall off during handling, and the L-shaped connector also serves as a stopper for the thumbscrew to prevent loosening of part of the cover, making it inexpensive and highly reliable. A power supply terminal device can be provided.
