Problems solved by technology

The existing cable bifurcation generally adopts a bifurcation overlapping structure bundled with a mixed braided winding rope. This structure has low reliability and reduces the service life of the cable.
In addition, the type mark and terminal mark of the existing engine cables are all made of metal plates, which are easy to scratch the outer sheath, causing the cable to be easily damaged during use and cannot work normally

Abstract

The invention provides a high-performance engine cable assembly, which solves the technical problems of low reliability and short service life of the existing engine cable. The engine cable assembly comprises a main cable, the main cable is divided into a plurality of branch cables through a plurality of bifurcation assemblies, two ends of the main cable and an end of the branch cable are respectively installed with tail accessories; The main cable comprises a main wire harness, and the branch cable comprises a branch wire harness. A polytetrafluoroethylene film is wound on the outer peripheryof the main wire harness and the branch wire harness. A wave-proof sleeve is arranged on the outer periphery of the polytetrafluoroethylene film, and the wave-proof sleeve of the main wire harness iscrimped on the outer periphery of the wave-proof sleeve of the branch wire harness at the bifurcation. The invention has the advantages of high reliability and long service life, and can be used forthe electric connection between the relevant accessories with electric products on the engine and the digital electronic controller and the engine comprehensive diagnostic device, and can transmit thecorresponding electric signals to realize the control function of the engine.

Description

Technical field [0001] The invention belongs to the technical field of engine cables, and relates to a high-performance engine cable assembly. Background technique [0002] Engine cables are generally used for the electrical connection of related accessories with electrical products on the engine, digital electronic controllers and engine comprehensive diagnostics, to transmit corresponding electrical signals, and realize the control function of the engine. The bifurcation of the existing cable generally adopts a bifurcation lap structure bundled with a mixed braided winding rope, which has low reliability and reduces the service life of the cable. In addition, the type mark and end mark of the existing engine cable are all metal plates, which are easy to scratch the outer sheath, which makes the cable easy to be damaged during use and cannot work normally. Summary of the invention [0003] In order to solve the above technical problems, the present invention provides a high-perf...
