Compared with prior art, the utility model has the following beneficial effects:
1. by branch joint convenient for operator to dividing cable to carry out installation fixation, so as to divide leader cable
Zhi Liyong improves the use value of cable, wherein leader cable periphery is fixed with protective shell, to leader cable and can divide cable
Junction carry out good protection, prevent the substances such as moisture from entering inside protective shell, avoid damaging cable.
2. passing through the combination of rupture pressure disc and pressure relief vent, effectively it can prevent cable from Decrepitation Phenomena occur, inside cable
When air pressure is excessively high, gas can break through rupture pressure disc, be discharged into gas inside pressure relief vent, and then can reduce inside cable
Air pressure, avoid damaging cable because air pressure is excessive.
3. the protective layer made by PVC material, can effectively prevent underground worm ant to bait cable surface, to make
Cable is not easily damaged, further improves the service life of cable.

Specific embodiment
To be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, below
In conjunction with specific embodiment, the utility model is further described.
As shown in Figs. 1-2, a kind of underground cable of reserved branch mouth, including leader cable 1 and protective shell 2, the leader cable 1
Periphery is fixedly connected with protective shell 2, and 2 side of protective shell is fixedly connected with branch joint 3, fixes inside the leader cable 1
Equipped with leading core 4, it is described lead 4 periphery of core and wrap be connected with insulating layer 5, the 5 periphery filling of insulating layer is connected with flame-retardant layer 6, institute
It states 6 periphery of flame-retardant layer and is fixedly connected with rupture pressure disc 7,7 periphery of rupture pressure disc is fixedly connected with low smoke and zero halogen layer 8, the low cigarette
8 periphery of Halogen layer is fixedly connected with waterproof layer 9, and 9 periphery of waterproof layer is fixedly connected with protective layer 10.
