Description

[Detailed Description of the Invention] The present invention relates to a lead wire outlet protector.

More specifically, the present invention relates to a protective device attached to the lead wire outlet at the top of the clamp cover.

A clamp cover is a device that covers the clamp part of a wire and electrically insulates it from other objects to maintain safety.
It has been used more widely than before.

However, among conventionally used devices, there are many in which the first lead wire outlet 1 has a flat shape with plenty of room to facilitate wiring work, as shown in FIG.

Such a first lead wire outlet 1 tends to be a perfect place for a sparrow's nest, and sparrows often build their nests in this location.

Then, due to the weight of the nest, the flexible piece 2 of the first lead wire outlet 1 bends downward, and a part of the nest structure falls into the clamp cover body 3, and the component falls into the cover body 3. 3
Block the drain provided in the

As a result, water cannot be discharged from inside the cover main body 3, resulting in poor insulation.

Furthermore, if a sparrow's nest is made in the first lead wire outlet 1, a snake will come after the nest, and since the snake has a long body, it is likely to straddle the electric wires and cause a short circuit.

Also, even if a nest is not created, a lot of debris will enter the clamp cover main body 3 from the first lead wire outlet 1 over a long period of time and will block the drain port of the clamp cover main body 3, so remove this debris. The disadvantage of this method is that the entire clamp cover main body 3 must be removed from the wire retaining clamp portion.

The object of the present invention is to cover the clamp cover for the clamping part of the clamping wire, and the first lead is closed so that the lead wire can be pulled out by a flexible piece that is long and has multiple releases in the direction of the clamping cable, which is formed on the top surface of the main body. A bottomless tapered box made of elastically deformable plastic that can be detachably attached to a wire outlet, and a second lead wire outlet with an area on the upper surface of the box that makes it difficult for sparrows etc. to build a nest therein for the lead wire. The second lead wire outlet is formed on a side surface of the box body so that the lead wire can be inserted into the second lead wire outlet port from the side surface of the box body. A slit that can be opened and closed on the left and right sides that communicates with the clamp cover is formed so that the closed state can be maintained by a locking tool, and the first
To provide a lead wire outlet protector in which at least one of the attachment position between the lead wire outlet and the box body and the position at which the lead wire is drawn out from the 21st J-wire drawer is movable in the direction of the dead wire. By,
The object is to eliminate the above-mentioned conventional drawbacks.

The protective device of the present invention will be described in detail below based on the embodiments of the present invention shown in the drawings. The protective device of the present invention is a bottomless box body 6 that can be fitted into the lead wire outlet 1 of the clamp cover body 3.

The shape of the box 6 may be a conical shape with a contact plate 7 at the bottom (Figure 3.4), a conical shape with a bellows 4 on the contact plate (Figure 2), or a rectangular parallelepiped with a bellows 4 on the top of the contact plate (Figure 3.4). Sometimes it is gable-shaped (Figures 5 and 6).

These boxes 6 do not have a bottom, and when fitted into the main body 3, the first lead wire outlet 1 becomes the bottom.

A second lead wire outlet 5 is provided in the upper part of the box 6, and a plurality of flexible pieces 2 close the second lead wire outlet 5.

As shown in Figures 3 and 4, the flat area of the plurality of flexible pieces 2 should be the area necessary for pulling out the lead wire 18 and where sparrows etc. cannot build nests. (Figs. 3 and 4), but it is preferable to have a double structure that extends from both the left and right sides (Fig. 5.6).

As shown in FIGS. 5 and 6, the width of the flat part made up of the plurality of flexible pieces 2 is set to a width necessary for drawing out the lead wire 18 and a width that does not allow sparrows to build nests therein. 8, and a small hole 9 may be bored at the end of the cut 8 to prevent tearing.

The box body 6 can be opened and closed left and right, and the degree of opening and closing is 3rd and 4th.
As shown in the figure, the second lead wire outlet 5 is inserted from the side of the box body 6.
It is also possible to provide a cut 19 that leads to the middle of the box 6, or to allow the box 6 to be opened and closed until it can be completely separated, as shown in FIGS. 5 and 6.

For example, the box 6 shown in FIG. 5 is a combination of two half-box members shown in FIG. 7 with their movable pieces 2 superimposed on each other, and can be completely separated.

After being tightened, the locking device 10 locks the locking device so that it does not open easily.

In order for the box body 6 to fit into the first lead wire outlet 1, an inverted T-shaped engagement protrusion 11 is fixed to the contact plate 7, and this protrusion 11 is inserted into the outlet 1. Accordingly, even if the position at which the lead wire 18 is drawn out from the first lead wire outlet 1 is not constant in the longitudinal direction of the hold-down electric wire 20, the box body 6 can be easily and reliably attached to the first lead wire outlet 1 (the third , 4).

At this time, it is also good to form projecting edges 12 at both ends of the contact plate 7.

Further, as shown in Figures 5 and 6, the size and shape of the bottom of the box body 6 are formed so that it can fit on the outer periphery of the first lead wire outlet 1, and there are notches on both left and right sides 1]1, 15r. 13, and the width of the notch 13 is made slightly smaller than the width of the upper edges 14 at both ends of the drawer opening 1 on the upper surface of the clamp cover main body 3 so that the clamp cover can be pushed in.

At this time, it is preferable that both the left and right side surfaces 15, 15r be made of a slightly thicker material, or that reinforcing ribs 16 be provided around the notch 13.

In addition, in the case of this gable type, even if the position at which the lead wire 18 is pulled out from the first lead wire outlet 1 is not constant in the longitudinal direction of the retaining electric wire 20, the second lead wire outlet 5 is long in the longitudinal direction of the retaining electric wire 20. There is no problem.

Furthermore, the inside of the box body 6 or the first lead wire outlet 1
It is also good to provide a protrusion 17 on the outside of the connector so that it cannot be easily removed after being fitted.

(Figures 8 and 9) The protective equipment of the present invention is made of rubber such as natural rubber and synthetic leather rubber, and plastics such as polyethylene, polypropylene, polyvinyl chloride, and polyethylene terephthalate.

Now, in order to use the lead wire outlet protector configured as described above, open the box body 6 from side to side and insert the lead wire 18 into the first lead wire outlet 1 of the clamp cover main body 3. Fit it while passing it through the drawer opening 5.

Next, the box body 6 is locked again using the locking tool 10 so that it does not open.

In this way, the clamp cover main body 3 is provided with a double lead wire outlet.

The upper part of the second lead wire outlet 5 is narrow and it is difficult for sparrows to build a nest there, but even if they did, the lead wire 18 outlet would be separated by the first lead wire outlet 1 and the second lead wire outlet 5. Since they overlap, a part of the constituent components of the nest will not fall into the clamp cover body 3.

Therefore, the drain port of the clamp cover main body 3 is not blocked, and the clamp cover consisting of the clamp cover main body 3 and the lead wire outlet protector can achieve the purpose of insulating the main body.

Next, the effects of the present invention will be explained.

The present invention consists of a first lead wire drawer which is formed on the upper surface of the main body of a clamp cover that is placed over the retaining clamp portion of the retaining wire, and is blocked by a plurality of flexible pieces that are long in the direction of the retaining wire so that the lead wire can be drawn out. A bottomless, tapered box made of elastically deformable plastic that can be detachably attached to the mouth, and a second lead wire outlet with an area on the upper surface of the box that prevents sparrows and the like from making nests, from which the lead wire can be pulled out. is formed by blocking it with a plurality of flexible pieces, and in order to allow the lead wire to be inserted into the second lead wire outlet from the side surface of the box body, there are left and right holes on the side surface of the box body that lead to the second lead wire outlet. A slit that can be opened and closed is formed so that it can be held in a closed state by a locking tool, and a cutout that can be opened and closed is formed in the clamp cover so that the first lead wire outlet of the clamp cover body is attached to the box body, and a cutout that can be opened and closed from the second lead wire outlet is formed. The lead wire outlet protector is configured such that at least one of the lead wire outlet positions is movable in the direction of the lead wire.

As a result, the present invention makes it easy to attach the clamp cover body and the lead wire outlet protector to the retaining clamp part containing the lead wire, and also prevents sparrows from building nests in the lead wire outlet eye. In addition, this lead wire outlet protector can be attached to the existing clamp cover body.
And since the second lead wire outlet is closed with a flexible piece, it is formed with enough room to accommodate changes in the lead wire outlet position, making it extremely easy to attach the clamp cover to the wire retaining clamp part. In addition to being easy to use, even if the flat part formed by the flexible piece of the second lead wire outlet is small and nests of sparrows etc. are not formed in the second lead wire outlet, it is difficult to prevent it from being exposed to wind and rain for a long time. Dust enters from the outermost second lead wire exit port, but the dust that enters from the second lead wire exit port accumulates in the flexible piece of the first lead wire exit port, which is not directly affected by the outside world, and is removed from the clamp cover. Hardly any of it falls into one body.

Therefore, when removing dust inside the clamp cover, it can be easily cleaned by removing only the lead wire outlet protector from the clamp cover.
