Embodiment 1

[0019] A right-angle lock fixed cable, the cable includes a cable core composed of multiple wire cores, the cable core is wrapped with a protective layer, the first filling layer is filled between the cable core and the protective layer, and the protective layer is connected to the cable core. The inner wire core is protected. Each strand of wire core includes multiple groups of core materials and insulating layers wrapped outside the multiple groups of core materials. Multiple groups of core materials may be distributed around the group core material. Multiple groups of core materials are wrapped with insulating layers, and the gap between the core materials and the insulating layers is filled with a second filling layer, which can cause interference between multiple groups of wire cores through the insulating layers. Of course, an insulating layer can also be provided outside each group of core materials, and the insulating layer on the core material is separated from the r...

Embodiment 2

[0022] On the basis of the first embodiment, the outer side of the upper surface of the locking strip is a slope.

Embodiment 3

[0024] On the basis of Embodiment 1 or Embodiment 2, the heights of the first groove-shaped structure and the second groove-shaped structure are equal, and the first groove-shaped structure reaches the outside of the insulating layer where the first groove-shaped structure is located. The distance of the cylindrical surface is equal to the distance from the second groove-shaped structure to the outer cylindrical surface of the insulating layer where the second groove-shaped structure is located, and the depth of the first groove-shaped structure is greater than the depth of the second groove-shaped structure.

Abstract

The invention discloses a right-angle lock fixed cable, which belongs to the technical field of power cables, and aims to provide a right-angle lock fixed cable, which improves the efficiency of setting a protective layer outside a multi-strand wire core. The cable includes a cable core and a protective layer; each strand of wire core includes multiple groups of core materials and insulating layers, and a second filling layer is filled between the core material and the insulating layer; the outer cylindrical surface of the insulating layer of each strand of wire core is A positioning protrusion is provided, a first groove-shaped structure is provided on the side of the positioning protrusion, a second groove is provided on the lower side of the positioning protrusion, and a raised edge protrusion is provided on the outer end of the second groove; There is a second groove-shaped structure on the outer cylindrical surface of the insulating layer of each strand of wire core, and a raised structure is arranged on the lower side of the second groove-shaped structure. Groove: when two adjacent wire cores are connected, a locking strip is installed in the space formed by the first groove-shaped structure of one wire core and the second groove-shaped structure of the other wire core.

Description

technical field [0001] The invention belongs to the technical field of power cables, and in particular relates to a right-angle lock fixed cable. Background technique [0002] With the rapid development of our country's national economy and the continuous improvement of people's living standards, the requirements for accelerating the construction of urban special-purpose power grids are becoming increasingly urgent. However, the application occasions of communication cables are complex, and the performance requirements for cables are extremely strict. Cables must have good mechanical and physical properties and be able to withstand various mechanical stresses, and the electrical properties will not deteriorate in harsh environments, so as to ensure long-term reliable work. However, existing cables generally have disadvantages such as poor shielding effect, low transmission speed, and poor anti-interference ability, especially for cables used in outdoor environments, which a...
