Problems solved by technology

Now most of the pre-branched cables can meet the standard requirements during production. After repeated bending and winding, the separation of the branch connector and the cable sheath will occur, resulting in poor waterproof performance of the cable and even electrical safety accidents. The reason is often that the hardness of the main cable, the connecting body, and the branch cables are different. When the force is bent, a stress concentration point is formed. The concentration point is basically at both ends of the connecting body. Under the action of external force, the sheath and the The tearing of the connecting body, the breakdown phenomenon occurs in the water immersion pressure test

Embodiment 1

[0029] See figure 1 and figure 2 , the manufacturing method of the aluminum alloy prefabricated branch cable of the present embodiment, comprises the following steps:

[0030] ①. Make main cable 1 and branch cable 2. The main cable 1 includes a main conductor 11 , a main cable insulation layer 12 and a main cable outer sheath 15 arranged in sequence from inside to outside. The branch cable 2 includes a branch conductor 21 , a branch cable insulation layer 22 and a branch cable outer sheath 25 arranged in sequence from inside to outside. Both the main conductor 11 of the main cable 1 and the branch conductor 21 of the branch cable 2 are aluminum alloy conductors.

[0031] ②. Connect the main cable 1 and the branch cable 2 together through the aluminum alloy CL-type clamp 3, and crimp the aluminum alloy CL-type clamp 3. There are no less than two indentations on the aluminum alloy CL-type clamp 3.

[0032] ③. Wrap a layer of self-adhesive waterproof tape on the aluminum all...

Embodiment 2

[0037] See image 3 , the manufacturing method of the aluminum alloy prefabricated branch cable of this embodiment is basically the same as that of Embodiment 1, the difference is that: the main cable 1 in step ① includes a main conductor 11, a main cable insulating layer 12, Main cable filling core 13, main cable wrapping tape 14 and main cable outer sheath 15; branch cable 2 includes branch conductor 21, branch cable insulating layer 22, branch cable filling core 23, branch cable winding The wrapping tape 24 and the outer sheath 25 of the branch cable; the main conductor 11 of the main cable 1 and the branch conductor 21 of the branch cable 2 are all formed by twisting a plurality of aluminum alloy conductor cores.

Abstract

The invention discloses a manufacturing method of an aluminum alloy prefabricated branch cable. The manufacturing method includes the following steps: (1) manufacturing a main cable body and a branch cable body; (2) connecting the main cable body and the branch cable body together through an aluminum alloy CL-type cable clamp, and pressing the aluminum alloy CL-type cable clamp in a connected mode; (3) winding the aluminum alloy CL-type cable clamp with a layer of self-adhesion waterproof adhesive tape, then wrapping the aluminum alloy CL-type cable clamp with two layers of hot melt adhesives, and then isolating cable cores with jackets; (4) processing the jacket of the main cable body and the jacket of the branch cable body through softening solvents to enable the surface of the jacket of the main cable body and the surface of the jacket of the branch cable body to be initially softened; (5) molding the main cable body and the branch cable body in an injection mode to form a whole. The aluminum alloy prefabricated branch cable manufactured with the manufacturing method has the advantages of being high in safety performance, good in insulating performance and electrical performance, high in shock resistance, easy and convenient to install and the like, and particularly has the excellent waterproof performance.

Description

technical field [0001] The invention relates to an aluminum alloy prefabricated branch cable and a manufacturing method thereof. Background technique [0002] In multi-storey and high-rise civil buildings, it is necessary to distribute power from the main line to each floor. At the earliest, manual on-site joints were used. Due to the cumbersome manufacturing process and high technical requirements, the construction cost is high and the construction period is long. Conductor contact resistance, The insulation strength and waterproof performance are difficult to guarantee, the airtightness of the branch joints is weak, and the safety performance is not guaranteed. Therefore, there are plug-in busbars and factory prefabricated branch cables. It is simple and takes up little space, and the plug-in box of the busbar may increase the number of distribution stages by one level; the closed busbar is suitable for dry and non-corrosive indoor places, and the waterproof and anti-corro...
