Description

Technical Field

[0001] The utility model relates to the technical field of cable protection, in particular to a wire harness bifurcated sleeve. Background Art

[0002] In the process of harness manufacturing, the binding of sheath branches is a common process, especially in the process of aircraft harness manufacturing. Due to the complexity of the system and the large number of branches, each fork needs at least three bindings. The binding process of the harness bifurcation is relatively complicated. For the binding of the single-side branch, there is also the risk of the binding point moving in series, and too much binding will form bulges and nodes on the harness, affecting the overall laying and aesthetics of the harness.

[0003] After searching, Chinese patent publication (announcement) number CN215298908U discloses a bifurcated multi-core integrated cable bundle, a section of polyvinyl chloride sheath and non-woven fabric are removed from one end of the multi-core integrated cable to form a multi-core integrated cable core, and the multi-core integrated cable core is divided into two component cable cores or multi-component cable cores, and a layer of non-woven fabric and a layer of polyvinyl chloride sheath are respectively arranged outside each component cable core in sequence, and a section of hollow silk rope is tied outside the polyvinyl chloride sheath of the multi-core integrated cable on one side of the bifurcation of the two-component cable core or multi-component cable core and outside the polyvinyl chloride sheath of the two-component cable core or multi-component cable core on the other side of the bifurcation, and a layer of hot-melt adhesive tape is wrapped around the hollow silk rope, and a shrink sleeve is put on the hot-melt adhesive tape and heat-shrunk, and the shrink sleeve is covered on the outside of the hot-melt adhesive tape. The bifurcated multi-core integrated cable bundle processed by bifurcation is easier to realize signal transmission between one-to-many instrumentation equipment than a single cable, which can reduce the overall number of cables used and simplify the arrangement.

[0004] Although the above patent can fork the cable into multiple groups, it can only fork at the end of the cable and cannot fork at other parts of the cable. Therefore, it is necessary to design a wire harness fork sleeve to solve the above problem. Utility Model Content

When the second branch pipe 7 is in use, the bifurcation of the cable can be carried out from the second branch pipe 7, and then the connecting pipe 9 can be threadedly connected to the outer surface of the screw tube 8 to protect and restrain the bifurcated cable, making it more convenient for the wiring harness to bifurcate and expanding the bifurcation.
