Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improved structure for operably covering a wire retention clamp cover on a clamp.

[0002]

2. Description of the Related Art A conventional wire retention clamp cover is known in which the left and right bodies are individually formed to face each other, and the upper side portions thereof are hinged and combined so that they can be opened and closed at the lower side portions. There is. When the clamp cover having such a structure is used, the lower side of the clamp cover is manually opened to cover the clamp.

[0003]

However, the place where such a clamp cover is used is a high place on the electric pole, and the mounting work is extremely dangerous. A work tool such as a hot stick is used for mounting on the vehicle. In this case, the clamp cover is easily closed even when the lower side is opened, which makes mounting work difficult. Therefore, an object of the present invention is to provide a clamp cover that solves such problems.

[0004]

A clamp cover according to the present invention is characterized in that a stay for temporarily holding the left and right bodies is provided at an inner position near the lower side in the longitudinal center of the left and right bodies. It is a thing.

[0005]

In the clamp cover of the present invention, when the lower sides of the left and right bodies are held open by the stay and the clamp cover is put on the clamp using a work tool such as a hot stick, the opening can be closed. Can be easily installed without. Then, when the clamp cover is put on the clamp, the stay comes into contact with the clamp and is pushed up, the end of the stay is released, the support is lost, and the opening of the clamp cover can be closed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes one of the left and right bodies forming the main body of the clamp cover K in which the left and right bodies are individually formed and opposed to each other so as to retain a cavity therein. Connecting pieces 2 and 2 having a shape shown in cross section are provided so as to face each other along the upper ends of the left and right bodies 1 and 1 over a required length,
The connecting piece 3 is integrally attached to these connecting pieces 2 and 2 in the form of a crown and hinges, and flanges 4 and 4 are provided on the lower side so that one flange 4 has buttons 5, 5 at appropriate positions. Two of them are provided so as to project, and the other flange 4 is provided with engagement holes 6 and 6 of these buttons 5 and 5 so as to be in close contact with each other. Further, the indirect live-wiring tools (P
The insertion portions 7, 7 for the C operation rod) are formed.

A grounding point cover 8 is provided at one end (left end in FIG. 1) of the left and right bodies 1, 1 to cover a portion for grounding work of the ground, and the other ends of the left and right bodies 1, 1 are provided. An opening 9 for tension insulators (right end in Fig. 1)
And the edging line openings 10 are provided at the positions above and respectively. The earth point cover 8 is formed in a half-cone shape with an opening at the lower side, and a support shaft 11 provided at the upper side of the base end of the earth point cover 8 is provided on the left and right bodies 1.
1 is mounted on the left and right bodies 1, 1 so as to be freely opened, and the left and right bodies 1 are fitted in the engaging recesses 13, 13 that are provided opposite to the left and right inner side surfaces near the base end thereof. , 1 projecting locking claws 14, 14 are fixed to the left and right bodies 1, 1 in a straight line, and the main line A is drawn out from an opening 15 provided at the tip. Also, an insertion portion 7a similar to the insertion portions 7 and 7 is provided at the tip of the upper side of the earth point cover 8.

As shown in FIGS. 2 to 4, the edge turning line opening 10 is provided with a large number of notches 16 facing each other on the opposite end edges of the left and right bodies 1, 1 to form a large number of fin-shaped pieces 17, and these are further formed. A large number of fin-shaped pieces 18 vertically project from the left and right bodies 1 and 1 inside the fin-shaped piece 17 to form a two-layer fin-shaped piece. In addition, the end edges of the left and right bodies 1, 1 are made to face each other in a flat shape in the middle of the tension insulator opening 9 and the bevel wire opening 10, and similar to those provided on the flanges 4 and 4 at the flat facing portions. The button and the engaging hole are provided so as to be sealed and polymerized.

Further, the left and right bodies 1 and 1 are provided with drainage holes 19 at three places respectively to prevent rainwater from collecting inside.

Numeral 20 is transversely attached to the left and right bodies 1, 1 at an inner position near the lower side at the substantially center of the left and right bodies 1, 1.
It is a stay for holding the open state of the lower side part.
As shown in FIG. 5, the stay 20 has a support shaft 2 on one side surface.
1 is provided in a protruding manner, and a locking claw 22 is formed at the other end to form an arcuate shape as a whole. Then, as shown in FIG. 6, the support shaft 21 is pivoted in a shaft hole 23 provided in one of the left and right bodies 1, and the locking claw 22 is detachably engaged with an engaging concave portion 24 provided in the other of the left and right body 1. By engaging them, the lower sides of the left and right bodies 1, 1 are held in an open state as shown in FIG.

Next, the use of the clamp cover of the present invention thus constructed will be described. As shown in FIG. 7, first, the earth point cover 8 is opened with respect to the left and right bodies 1, 1, and the flanges 4, 4 disengage the respective buttons 5, 5 from the respective engagement holes 6, 6 and the clamp cover. With the left and right bodies 1, 1 open outward, the locking claws 22 at the tips of the stays 20 are fitted into the engaging recesses 24. Then, sandwich one flange 4 with a work tool T such as a hot stick,
The edging wire B is inserted through the edging wire opening 10, and then the work tool T is lifted upward as it is as shown in FIG. 7, and then the opened portions of the left and right bodies 1 and 1 of the clamp cover K are located above the clamp C. The stay 20 that opens the left and right bodies 1, 1 of the clamp cover K comes into contact with the clamp C and is pushed up when the stay 20 is moved downward so that it stays in the horizontal direction. The locking claw 22 at the tip is disengaged from the engaging recess 24, and the stay 20 is fixed to the support shaft 2.
Rotate about 1 as a fulcrum and stand up along the inner wall of one of the left and right bodies 1 as shown by the chain line in FIG.

Since the lower side portions of the left and right bodies 1 and 1 which have lost the support of the stay 20 naturally close their openings, the opposing flanges 4 and 4 are grasped by a work tool T such as a hot stick or the like so that the clamp cover K is resistant. The opening 9 for the insulator is attached to the insulator a.
Then, the buttons 5 and 5 provided on the flanges 4 of the left and right bodies 1 and 1 are engaged with the engaging holes 6 and 6 to cover the clamp C with the clamp cover K.

After covering the clamp C with the clamp cover K, the earth point cover 8 is rotated downward from the spindle 11 as a starting point to cover a part of the main line A and an opening 15 provided at the tip of the earth point cover 8. The main line A is clamped by.

[0014]

As described above, in the wire retention clamp cover of the present invention, the stay securely holds the open state of the lower side of the left and right bodies, and this stay is operated by the operation of storing the clamp in the left and right bodies. Since the openings of the left and right bodies lose their support and the openings of the lower side of the clamp cover can be naturally closed, the operations of the clamp cover are hindered. It is possible to easily carry out the work of covering the clamps. Further, since the fin-shaped piece is provided in two layers in the rimming wire opening, it is possible to reliably prevent birds and beasts and snakes from entering the clamp cover through the opening.
