Detailed Description

The technical solution of the present invention is further explained by the accompanying drawings and examples.

Unless defined otherwise, technical or scientific terms used herein shall have the ordinary meaning as understood by those of ordinary skill in the art to which the invention belongs. The use of "first," "second," and the like in the description of the invention does not denote any order, quantity, or importance, but rather the terms "first," "second," and the like are used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that the element or item listed before the word covers the element or item listed after the word and its equivalents, but does not exclude other elements or items. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.

As shown in the figure, a stable form catenary terminal includes a support frame 2 on the underside of a catenary 1, the support frame 2 providing support for the catenary 1. The upper part of the carrier cable 1 is connected to the support 2 through a U-shaped cable clamp 3, so that the carrier cable 1 is stably fixed.

The bracket 2 is of an integral structure, and as one embodiment, the bracket is made of steel bars. The support comprises a supporting part 5 of an equilateral triangle structure and bearing parts 4 which are arranged on two sides of the top end of the supporting part 5 and extend outwards, and the bearing parts 4 are positioned below the carrier cable to provide support for the carrier cable. The bearing part 4 is perpendicular to the plane of the support part 5, so that the bearing part 4 is perpendicular to the plane of the support part 5. The acute angle of the supporting part 5 is 40 degrees, the vertex angle thereof is 100 degrees, the whole structure is reasonably arranged, and the stable support of the carrier cable 1 is ensured.

The lower ends of both sides of the supporting part 5 are fixed by a first fixing plate 11, both sides of the bottom thereof are connected to the pillars by a second fixing plate 12, and the position of the supporting part 5 is fixed by the first fixing plate 11 and the second fixing plate 12.
