Description

[Detailed Description of the Invention] The present invention relates to an improvement of a hanger for an insulated contact wire.

2. Description of the Related Art As a hanger for an insulated contact wire, there is a known hanger that includes a hanger insulating member that elastically holds an insulated contact wire, and a hanger metal fitting that elastically holds the hanger insulating member.

However, in this type of hanger,
The connection between the insulated contact wire and the hanger insulating member as well as the connection between the hanger insulating member and the hanger fitting is a fitting and locking method that utilizes the elasticity of the hanger insulating member and the hanger fitting, and is different from the bolt tightening method. It is difficult to dissociate the above bonds. Therefore, it is disadvantageous for work such as re-covering an insulated trolley.

The insulated contact wire hanger according to the present invention was devised in view of the above points, and is a plastic hanger insulated in which both side pieces that clamp both sides of the insulated cover of the insulated contact wire are joined by a bridge piece in the middle. and a hanger metal fitting having a square cross section that holds the hanger insulating member, cut holes are provided at both shoulder corners of the hanger metal fitting, and an edge of the cut hole is provided at the upper end of each side piece of the hanger insulating member. This configuration is characterized in that it is provided with a claw that locks into.

The present invention will be explained below with reference to the drawings.

FIG. 1 shows a plastic hanger insulating member and a hanger metal fitting used in the present invention, together with an insulated contact wire.

In FIG. 1, A indicates an insulated contact wire, 1 is a contact wire, and 2 is a plastic insulating cover. Locking grooves 21, 21 are provided at the upper ends of both sides of the insulating cover 2, and a locking groove 22 is provided on the upper surface of the insulating cover 2, respectively.

B indicates a hanger insulating member, in which both side pieces 3, 3 are joined by a bridge piece 4 in the middle. The bridge piece 4 is provided with a lower intermediate piece 41 and an upper intermediate piece 42.

At the lower end of each side piece 3, 3, there are protrusions 31, 31 that fit into the locking grooves 21, 21 on each side surface of the insulating cover 2 on the inner surface side, and an insulation distance extending to the side surface of the insulating cover on the outer surface side. A canopy 32 is provided for increasing the height. Furthermore,
The lower half of the outer surface of each side piece 3, 3 has a tapered surface 33, 33 for tightly fitting a hanger fitting to be described later.
A notch 320 is provided in the center of the eaves 32 to prevent rainwater from accumulating. On the other hand, a notch 3 is provided at the upper end of each side piece 3, 3 to facilitate attachment of a hanger metal fitting, which will be described later.
4 and 34 are provided. 35 is the notch 34,
This is a locking claw provided at the upper end of the central portion 340 divided by 34, and is locked to a hanger metal fitting to be described later. This claw 35 is provided with a tapered guide surface 350 for facilitating the installation work of the hanger fitting. A protrusion 410 is provided at the lower end of the lower intermediate piece 41 to fit into the groove 22 on the upper surface of the insulated cover of the insulated contact wire A.

C indicates a hanger metal fitting having a substantially square cross section, and notch holes 5, 5 are provided at both shoulder corners. Both side pieces 6, 6 have cut slits 61,
61,... are provided, and this cut slit 6
A central portion 610 divided by 1 and 61 is slightly slanted outward.

In FIG. 1, if the upper ends of both side pieces 3, 3 of the hanger insulating member B are narrowed with fingertips, the lower ends of both side pieces 3, 3 can be expanded using both ends of the bridge piece 4 as nodes, so that the hanger insulating member Attaching B to the insulated contact wire A is easy. Also, when attaching the hanger metal fitting C to the hanger insulating member B, the outer warped portions 610, 61 of both side pieces 6, 6 of the hanger metal fitting
0 to the center portion 34 of both side pieces of the hanger insulating member B
Tapered guide surface 3 of upper end claws 35, 35 of 0,340
50,350 and its central portion 34
0,340 can be bent inward to easily fit tightly into the tapered surfaces 33, 33 of the lower halves of both sides of the insulating member, and the hanger fitting C can be easily attached to the hanger insulating member B.

Fig. 2 shows a state in which an insulated contact wire is fixed to a building side cross arm D using a hanger according to the present invention, and the hanger insulating member B is attached to both shoulders of the hanger metal fitting C at the claws 35, 35 at the upper end of both side pieces. It is locked to the edges of the notch holes 5, 5. 7 is bolt and 8 is nut.

In FIG. 2, if the upper ends 35, 35 of both side pieces of the hanger insulating member B are pinched with fingertips through the notch holes 5, 5 on both shoulders of the hanger fitting C, the claws 35, 35 of the hanger insulating member B and the hanger It is possible to easily release the lock from the notch holes 5, 5 on both shoulders of the metal fitting C,
Therefore, the hanger insulating member B and the hanger fitting C can be separated with one touch. After separating the hanger insulating member B, by pinching the upper ends of both side pieces of the hanger insulating member B with your fingertips and narrowing them, the lower ends of both side pieces can be expanded as described above, so that the hanger insulating member B and the insulating trolley can be It can also be easily separated from line A.

As mentioned above, the insulated contact wire hanger according to the present invention uses elasticity to fit and lock between the insulated contact wire and the hanger insulating member, and between the hanger insulating member and the hanger fitting. The insulated contact wire can be easily separated from the hanger by simply pinching and narrowing the upper ends of both sides of the hanger insulating member in the notched holes on both shoulders of the hanger metal fitting with fingertips. Therefore, it is advantageous for replacing insulated contact wires, etc.
