Description

[Detailed description of the invention] The present invention relates to a wire retention clamp cover that protects copper wire, aluminum wire, etc. retention clamps and maintains safety by electrically insulating them from surrounding objects and workers. It is something.

Conventional clamp covers have only one lead wire outlet 2 from which elastic tongues 1 protrude from the left and right sides, and most have flat surfaces as shown in FIG.

Such a lead wire outlet 2 tends to be a perfect place for sparrows to build their nests, and sparrows often build their nests on this outlet 2.

Then, due to the weight of the nest, the elastic tongue piece 1 that covers the drawer opening 2 bends downward, and a part of the nest component falls into the clamp cover body 4, causing the drainage provided in the cover body 4 to collapse. Cover your mouth.

As a result, rainwater that has entered the clamp cover main body 4 cannot be drained away, resulting in poor insulation.

Furthermore, if a sparrow nest was built in the drawer 2, a snake would come for the nest, and since the snake has a long body, it would easily straddle the wires and cause a short circuit.

In order to solve this problem, the inventor of the present invention conducted extensive research and found that it would be sufficient to double the lead wire outlet and create a specific shape, thereby completing the present invention.

That is, the gist of the present invention is that the elastic tongues 1u and ld are attached from the left and right sides.
The lead wire outlet 2 protruding from the lead wire outlet 2 is provided twice, and the flat part at the top of the outer upper lead wire outlet 2u is made narrower than the flat part of the inner lower lead wire outlet 2d.
Moreover, the electric wire retaining clamp cover 3 is characterized in that the elastic tongue pieces 1u of the outer lead wire outlet 2u are overlapped.

The present invention will be explained in detail below with reference to embodiments shown in the drawings.

Elastic tongues lu and ld protrude from both left and right sides of the outer and inner lead wire outlet openings 2u and 2d.

In this case, as shown in Figures 4 and 5,
It is necessary that at least the outer right and left tongue pieces 1u are overlapped near the tips.

The tongue piece 1u that covers the outer drawer opening 2u may protrude obliquely upward as shown in FIG. 4, and be bent at the tip so as to be substantially parallel to the inner drawer opening 2d.

Reference numeral 4 denotes a cover main body, whose upper end portion is integrally connected and can be opened and closed from the connected portion 5 in a face-to-face manner.

The integrated cover 4 is also provided with a wire insertion opening 6 and a clamp insertion opening 7, and after closing, a locking tool 8 is provided.

To use the retaining clamp cover 3 of this example configured as described above, open the cover main body 4, insert the retaining clamp 10 with the electric wire 9 held in place in one cover piece, and connect the electric wire 9 to the outside and inside. The cover main body 4 is closed with the lead wire drawn out from the lead wire outlet 2 and the electric wire insertion port 6.

As described above, the present invention has a double lead wire outlet 2 with elastic tongues 1 protruding from the left and right sides. The piece 1 is pushed open and comes into close contact with the periphery of the electric wire 9, and the other elastic tongue pieces 1 come into close contact with each other to close the outlet openings 2u and 2d.

Therefore, the opening is completely closed, and even if a sparrow builds a nest above the upper lead wire outlet 2u and the components of the nest fall down, the lower outlet 2d will be closed inside the cover main body 4. prevent you from falling.

However, in the present invention, the flat part at the top of the upper drawer opening 2u is narrower than the flat part of the lower drawer opening 2d, making it difficult for sparrows to build nests.

In addition, when the present invention is used in a coastal region, since the double drawer opening 2 is used to block the cover from the outside, wind and rain containing salt will not enter the cover body 4, which is highly effective in preventing salt damage.

In particular, in the present invention, since the elastic tongues 1u of the outer lead wire outlet 2u are overlapped, in the event that a sparrow makes a nest 11, the elastic tongues 1u can be moved downward as shown in FIG. Since the overlapping portion 1u prevents bending, it is highly effective in preventing the constituent parts of the nest 11 from falling downward.

Further, when the electric wire 9 is pulled out from the outer lead wire outlet 2u, the elastic tongue piece 11 is pushed open, but at this time, in the present invention, since there is an overlapping portion 1W, the opening area is as shown in FIG. The overlapping portion can be made smaller by 1W.

Therefore, it is difficult for rain, wind, sparrows, etc. to enter through the opening.

If there is no overlapping portion, the opening area will become large as shown in FIG.
