[0001] The utility model belongs to the technical field of environment-friendly long-life electric wires, in particular to an environment-friendly long-life low-smoke halogen-free cloth electric wire. Background Art

[0002] Wires are carriers for conducting electrical energy. They are composed of one or more soft conductors and a light and soft insulation layer wrapped around the conductors. The conductor is used to transmit electrical energy and is the main part of the wire; the insulation layer is used to electrically isolate the conductor from the ground and different conductors from each other to ensure the transmission of electrical energy. It is an indispensable part of the wire structure.

In addition, there is a lack of protective devices at the connection points of the wires, which reduces the stability of the connection. Therefore, in order to solve the above problems, an environmentally friendly, long-life, low-smoke, halogen-free cloth wire is proposed. Utility Model Content

The insulating layer 2 can protect the wire 3 inside the protective cover 1, reducing the occurrence of static electricity generated by friction between the wires 3. When connecting the wires 3, the personnel slide the sliding tube 6 through the ball 5 inside the installation frame 4. When sliding to the connection point, the installation assembly 7 is used to fix the sliding tube 6. After the sliding tube 6 is fixed, the sliding tube 6 can protect the connection point of the wire 3.

[0024] like Figures 1 to 4 As shown, the mounting assembly 7 includes a limiting ring 71 fixedly mounted on both ends of the sliding tube 6, a through groove is provided on the top of the limiting ring 71, a threaded rod 72 is penetrated through the internal thread of the through groove, one end of the threaded rod 72 is rotatably connected to a clamping plate 73, the diameter of the clamping plate 73 is adapted to the diameter of the protective sleeve 1, and the inside of the clamping plate 73 is in contact with the surface of the protective sleeve 1.

[0025] After the personnel moves the sliding tube 6 to the connection point of the wire 3, the threaded rod 72 is rotated through the limit ring 71.
