DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
On the other hand, the divided end of the distribution line protection cover 100 is expanded and attached, and then the next distribution line protection cover 100 is attached to the distribution line 106 in the same manner as described above, and the gooseneck projection 102 at the tip is first attached. Large-diameter portion 10 of the distribution line protective cover 103 of
When the electric wire protection cover 100 is sequentially connected in the same manner as described below, the electric wire protective cover 100 is moved in the direction shown by the arrow in FIG. The steel wire portion 109 hooked on the suspension wire 108 of the cable hanger 107 as shown in an enlarged view in FIG.
There is a problem in that the top of the hook catches on the back side corner portion 110 of the large-diameter pipe portion 105 and prevents the distribution line protection cover 100 from moving smoothly in the lateral direction.

When the gooseneck projection 102 at the tip is moved in the lateral direction, the cable hanger 1 as shown in FIG.
It collides with the top of the steel wire portion 109 of No. 07, which also hinders the smooth movement of the distribution line cover 100. further,
As shown in FIG. 14, when the distribution line cover 100 is connected to the next distribution line cover 100 and moved laterally, as shown in FIG. 15, the steel wire portion 109 of the cable hanger 107 inside the large diameter pipe portion 105 There is a problem that it is stuck in the gap between the gooseneck-shaped projection 102 and the back-side corner portion 110 and becomes immobile. Furthermore, since there is a large gap in the joint pipe portion 103 with the main body pipe 101, there is rattling in the connected portion in the connected state, and there is a problem of poor stability. Therefore, the object of the present invention is to improve a distribution line protective cover that solves all the problems found in the prior art.

[0005]

In order to achieve such an object, the distribution line protective cover of the present invention is required to have a gooseneck-shaped projection at its tip at one end in the longitudinal direction of a body tube formed in a long shape. In the distribution line protective cover, which forms a fitting pipe portion of a length, and which is provided with a joint pipe portion into which the fitting pipe portion is fitted at the other end in the longitudinal direction of the main body pipe so that the whole is in a half-cylindrical shape,
The fitting and inserting tube portion is formed to have a larger diameter than the main body tube, and the inner peripheral surface of the connecting portion between the main body tube and the fitting and inserting tube portion is formed into a tapered surface, and the inner diameter of the fitting portion of the joint pipe portion is the outer diameter of the fitting and inserting tube portion. And a rear end side corner portion of the large-diameter pipe portion that forms a large-diameter pipe portion that locks a gooseneck-shaped projection having an inner peripheral surface formed into a taper surface at the rear end of the fitting portion. Is formed in a tapered tubular shape.

[0006]

[Operation] When the distribution line protection cover is attached to the distribution line and moved laterally, the fitting tube at the tip and the gooseneck projection are formed to have a diameter larger than that of the main body tube, and By forming the corners on the end side in a tapered tube shape, the top of the steel wire part of the cable hanger does not hit or get caught on the inner wall surface of the main body pipe, and the distribution line protective cover can be moved laterally smoothly. You can Then, even when the next distribution line protection cover is connected to this distribution line protection cover, since the gooseneck projection at the tip of the fitting pipe part is fitted and connected to the large diameter pipe part of the joint pipe part, The taper surface provided on the inner peripheral surface of the gooseneck-shaped projection that is fitted to the upper part inclines upward with respect to the moving direction of the distribution line protection cover, and the top of the steel wire part of the cable hanger against the movement of the distribution line protection cover Since it can move without being caught, it can be attached to the distribution line over a desired length while connecting the wire protection cover at one place.
