Electricity, it is also applied for the electric power systems such as tunnel, airport, bridge, highway.Pre-branched cable is mainly made up of four parts：Main cable,
Branch line, branch joint and related accessories；Traditional branch cable is by dividing straight joint (insulation sleeve) by main cable with dividing
Branch line links together, typically integrally formed, therefore is difficult maintenance when joint is broken down.
A kind of separable pre-branched cable (notification number CN206021931U) of patent, disclose a kind of separable pre- point
Branch cable, including main conductor core, tap conductor core and the connection for connecting main conductor core, tap conductor core
Part；Main conductor core is coated with branch's sheath with tap conductor core junction；Connector includes the clip for U-shape structure,
The bottom of clip is outwardly to form a small neck, and the upper end both sides of clip are respectively arranged with hangers, and both sides hangers passes through bolt
Link together；Insulation rubber cushion is provided between hangers and bolt.The patent is easy to leader cable and branch line by setting up clip
Connection and separation, but last fixation is still wrapped up using branch's sheath, when electrician overhauls, it is still desirable to destroy branch
Set, is still not easy to repair；And cause the wasting of resources.
According to problems of the prior art, the utility model offer is a kind of easy to disassemble, is easy to branch's electricity of maintenance
Cable.
