Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a plastic hanger insulation member for an insulated contact wire.

When an insulated contact wire is fixedly supported by a hanger metal fitting, the insulated contact wire is sometimes held between the hanger insulating members and the hanger insulating member is held between the hanger metal fittings from the viewpoint of electrical insulation. The present invention aims to provide a new hanger insulating member for the above-mentioned insulated contact wire, which can be easily attached to and removed from the insulated contact wire and can stably support the insulated contact wire. Both side pieces that sandwich both sides of the insulating cover of the contact wire are connected in the middle by a bridge piece, and the bridge piece is provided with an intermediate piece that supports the upper surface of the above-mentioned insulating cover. is provided with a locking pawl, and a hanger metal fitting with a cross-sectional shape and cut holes in both shoulders is fitted across both side pieces, and a hanger metal fitting is fitted across both side pieces, and a hanger metal fitting is provided with a locking claw at the upper end of each side piece. The device is characterized in that a claw is locked in each of the cut holes.

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

FIG. 1 shows a plastic hanger insulating member according to 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 shows a hanger insulating member according to the present invention, in which both side pieces 3, 3 are joined by a bridge piece 4 in the middle, and the bridge piece 4 is provided with a lower intermediate piece 51 and an upper intermediate piece 52. ing.

At the lower end of each of the side pieces 3, 3, there are locking grooves 21, 2 on each side surface of the insulating cover 2 on the inner side.
The protrusions 31, 31 to be fitted into the insulating cover 1 are each provided with an eave 32 on the outer surface side to increase the insulation distance to the side surface of the insulating cover.
Furthermore, the lower half of the outer surface of each side piece 3, 3 has a tapered surface 33 for tightly fitting a hanger metal fitting, which will be described later.
A notch 320 is provided in the center of the eaves 32 to prevent rainwater from accumulating. On the other hand, cutouts 34, 34, . . . are provided at the upper ends of each of the side pieces 3, 3 to facilitate attachment of hanger metal fittings, which will be described later. Reference numerals 35 and 35 are locking claws for a hanger metal fitting, which will be described later, and are provided with a tapered guide surface 350 for facilitating the installation work of the hanger metal fitting. A protrusion 510 is provided at the lower end of the lower intermediate piece 51 to fit into the groove 22 on the upper surface of the insulating cover of the insulated contact wire.

Fig. 2 shows the insulated contact wire A being held between the hanger insulating member B according to the present invention, and when the upper ends of both side pieces 3, 3 are pinched with fingertips, the bridge piece 4
Since the lower ends of both side pieces 3, 3 are spread out with both ends of the handle as nodes, attachment and detachment of the hanger insulating member B to and from the insulated contact wire A is easy. Further, since the insulating trolley can be supported at three points: the upper ends of both sides of the insulating cover and the upper surface of the insulating cover, the supporting state is stable.

FIG. 3 shows an example of the hanger metal fitting C held by the hanger insulating member B, which has a cross-sectional shape and has cut slits 61 in both side pieces 6, 6.
61, . . ., cut holes 62, 62 are provided in both shoulder portions, respectively.

The central portions 60, . A fourth section is formed on the tapered surface 33 on the side surface of the hanger insulating member by passing through the tapered guide surface 350 of the upper end claw 35 and bending the tapered guide surface portion inward.
As shown in the figure, it can be easily and tightly fitted. In addition, as shown in FIG. 4, the claws 35 at the upper ends of both side pieces of the hanger insulating member
Can be locked to 2. Therefore, the hanger metal fitting can be securely attached to the hanger insulating member. Also, hanger metal fittings C
By pinching the claws 35, 35 at the upper ends of both sides of the hanger insulating member B with your fingertips through the cut holes 62, 62 on both shoulders, the hanger insulating member B can be separated from the hanger fitting C with one touch.

In FIG. 4, reference numeral D designates a building arm arm and 7 designates a bolt. When the bolt 7 is tightened, the upper intermediate piece 52 of the hanger insulating member B can prevent the bolt 7 from falling off.

The plastic hanger insulating member for an insulated contact wire according to the present invention has the above-described configuration, and can be opened and expanded by simply pinching the upper ends of both side pieces with fingertips, and can be easily attached to and detached from the insulated contact wire. . Furthermore, since the insulated contact wire can be supported at three points, the lower ends of both side pieces and the lower end of the intermediate piece, the insulated contact wire can be stably supported.
