Problems solved by technology

Undoubtedly, the existing branch wires and cables at least have resistance changes and virtual connections that are prone to cold and hot cycle currents at the connection point between the main line and the branch line; It is inconsistent with the material of the main line and the branch line and the secondary molding process, which is very easy to cause poor sealing and even leakage problems, which reduces its insulation performance and seriously affects the quality of power transmission; the manufacturing process is complicated and special equipment is required can only be produced, so that the market supply price is relatively high, etc.

Embodiment Construction

[0041] One of the specific embodiments is shown in Figures 1, 2 and 3. A branched electric wire, consisting of a main line 2 composed of a metal conductor 1, a branch line 3 composed of a metal conductor 1, and an insulating layer 4 wrapped on the main line 2 and the branch line 3; in the main line 2 A plurality of metal conductors 1 are extracted at any distance to form a branch line 3, and the main line 2 and the branch line 3 are connected parallel to each other by a connecting layer 5 through an insulating layer 4. On the trunk line 2 where the metal conductor 1 is extracted, a fixing piece 6 for fastening the trunk line 2 is provided; the material of the fixing piece 6 is the same as that of the metal conductor 1 . The distance between the main line 2 and the branch line 3 parallel to each other = the thickness of the insulating layer 4 of the main line 2 + the thickness of the insulating layer 4 of the branch line 3 + a coefficient of 1 ~ 3mm; both the main line 2 and th...

Abstract

The invention consists of main cable composed of metal conductor or cored metal conductor, branch cable composed of metal conductor or cored metal conductor, and insulating layer or sheath layer covering the main cable and branch cable. The branch cable is composed of metal conductor and cored metal conductor which is drawn out from several points on main cable. The main cable is connected with branch cable by bonding layer through insulation layer and sheath layer. There is no contact point in main cable and branch cable. The manufacturing method includes following steps: twisting line; tapping; leasing cord; collating; extruding wire.

Description

technical field [0001] The invention relates to a branching wire and cable and a manufacturing method thereof, belonging to the wire and cable technology. Background technique [0002] The existing prefabricated branch wires and cables are also called branch wires and cables, such as the wires and cables produced and marketed by many well-known domestic cable companies, Japan Fujikura Cable Company and Japan Jiayou Electric Industry Co., Ltd. And the notification number CN2349642Y etc. that is applied for by the applicant, all adopt the main line and the branch line to be buckled by crimping parts or wire wrapping, then pass through the technical scheme of molded outcoat or title head at joint. Undoubtedly, the existing branch wires and cables at least have resistance changes and virtual connections that are prone to cold and hot cycle currents at the connection point between the main line and the branch line; It is inconsistent with the material of the main line and the br...
