Description

[Detailed description of the invention] [Field of industrial application] The present invention is designed to prevent birds and beasts from entering through the edge line opening of the clamp cover and causing electric shock accidents by fitting the clamp cover into the edge line opening. This invention relates to a cover for preventing damage from birds and animals.

Here, the term "edge line" refers to the two wires that come from the front and back of the utility pole on which the electric wire (main line) is generally installed.
A wire used to connect two wires by first securing the ends of the main wires to clamps moored to utility poles, then passing them between both clamps. The connection portion of the electric wires (main wire and edge wire) in the clamp is usually covered with a clamp cover.

[Disadvantages of conventional example]

Conventionally, the edge line opening of the clamp cover was
It is known that a lid is provided with, for example, a zigzag line cut in the center to prevent birds and animals from entering the clamp cover. However, when the line is passed through this opening, a gap is created near the line, and this gap still allows snakes, birds, and field mice to enter, and furthermore, rainwater can flood the area. There were imperfections.

Therefore, for example, in the "lead wire outlet protector" described in Utility Model Application Publication No. 55-12726, the "lead wire outlet" corresponds to the "edge wire opening" of the present invention.
By attaching a specially constructed protective device to the drawer, the space between the drawer openings (corresponding to the openings) is closed;
Prevent birds and animals and rainwater from flooding. The protective device used here is a bottomless box that can be fitted into the lead wire outlet of the clamp cover main body, and has a second lead wire outlet at the top and can be opened and closed from side to side. For example, the protective device may have a conical shape in which the bottomless box has a lower contact plate, and the contact plate also has an inverted T-shaped engagement protrusion, or the box may be a rectangular parallelepiped with an upper portion thereof. Some are gable-shaped and have a notch. According to such an outlet protector, a double lead wire outlet is provided at the upper part of the clamp cover and the upper part of the box body. Therefore, even if foreign objects enter the inside of the box, they are prevented from falling further into the clamp cover main body.

However, the bottomless box is connected by fitting the box into the lead wire outlet by inserting the inverted T-shaped engagement protrusion provided on the lower surface of the lower contact plate into the lead wire outlet as described above. It is something.

At this time, the inverted T-shaped engagement protrusion only engages the elongated rod in the center with the outlet, and is therefore fragile and unstable as a fitting means. For this reason, if birds or animals apply force, they can tilt the box and create a gap between it and the lead wire outlet, creating a risk of intrusion. Furthermore, under strong winds, the box body may become twisted, creating a gap between the box body and the lead wire outlet, which may lead to infiltration of rainwater or the like.

[Purpose and structure of the present invention]

The purpose of the present invention is to solve the above-mentioned problems of the conventional method, and to provide a cover for preventing damage to birds and animals in a clamp cover that firmly fits into the edge line opening and completely prevents the intrusion of birds and animals. The flange is formed by longitudinally cutting one side of a trapezoidal base whose bottom surface is wider than the edge line opening provided in the main body of the clamp cover and which is hollow inside, and by attaching a flange to the separated edge thereof. are provided with engaging portions that removably engage with each other, and a fitting tube portion that fits into the edge line opening is provided vertically on the lower surface of the base, and the cross section of the fitting tube portion is slightly smaller than the bottom surface of the base. While making the size smaller, it is formed approximately equal to the edge line opening, and furthermore, a holding cylinder part is provided upright on the upper part of the base body so as to be biased to one side from the center of the base body, and furthermore, the holding cylinder part and the above-mentioned fitting The joint tube portion was cut longitudinally along the longitudinal line of the base body and formed to be openable and closable.

[Operation of the present invention]

(1) One side of the base body, the holding cylinder part and the fitting cylinder part provided on the upper and lower surfaces of the base body are integrally longitudinally cut, and an engaging part is provided on the flange opposite the separated edge of the base body. Opening and closing of the protective cover is extremely easy.

(2) The cross section of the fitting cylindrical portion is made slightly smaller than the bottom surface of the base body, while being approximately equal to the edge line opening. Therefore, since the fitting tube part of the cover for preventing damage to birds and animals is tightly and firmly inserted into the opening of the edge line, no gap is created due to external pressure, and birds and animals do not enter the clamp cover main body.

(3) Since the holding cylinder installed on the top of the base body is biased to one side from the center of the base body, if the holding cylinder unit is aligned with the direction in which the hemming line is pulled out, the line can be drawn easily. Since the wire can be drawn out accurately over the shortest distance, and the wire can always be pulled out in the opposite direction to the engaging portion of the preventive cover, there is no risk of applying an unexpected load to the engaging portion itself.
