Background technology
Prefabricated branch cable be factory required according to cable user master, branch cable model, specification, section, length and
The indexs such as branch location, use a series of production equipment specials, the band to be completed on flow production line in factory
The cable of branch.
Prefabricated branch cable is due to power supply safety is reliable, use cost is low, installation is simple, environmental requirement is low, exempts to tie up
The advantages that shield, thus obtained it is extensive popularization and application, be widely used in house, office tower, tunnel, hotel,
The distribution systems such as hospital, market, being also used for backbone has lighting system such as street lamp power supply, road lamp power supply, highway, bridge, the tunnel of branch line requirement
Road and airfield runway etc..
The prefabricated branch cable of the prior art is due to being to be prefabricated in the factory, therefore master, branch cable model, specification, section, length
Degree and branch location etc. have all been fixed.When there is change in design, design mistake, measure mistake, installation deviation, branch line circuit mistake
It is necessary to re-work installation at the scene during the problems such as load, the scratch damage of branch line circuit cannot use, reliability is caused not protect
Barrier, and whole branch cable is often scrapped, and also brings material, manpower, time etc. to lose.
On the other hand, some branch line circuits need two branch lines at the same time, or because of certain on already installed circuit
Kind needs and increases branch line.Existing branch cable obviously cannot solve the above problems.
Moreover, existing prefabricated branch cable is usually to wrap up one layer of insulating tape in the joint of leader cable and branch cable
Insulate to conductor, it is impossible to prevent the infiltration of moisture, poor sealing performance.
Therefore, how to solve the problems of the above-mentioned prior art becomes the direction of field technology personnel effort.
The content of the invention
It is an object of the invention to provide a kind of prefabricated branch cable, can be fully solved above-mentioned the deficiencies in the prior art it
Place.
The purpose of the present invention is realized by following technical proposals：A kind of prefabricated branch cable, including leader cable and connection
The junction injection molding branch connected body of branch cable in leader cable side, leader cable and branch cable, the leader cable
Including leader cable conductor, insulating layer and cable cover(ing) are set gradually outside leader cable conductor；Branch cable includes branch cable conductor,
Insulating layer and cable cover(ing) are set gradually outside branch cable conductor；C-type conductor is used between leader cable conductor and branch cable conductor
Connector connects, it is characterised in that：Leader cable in branch's connected body and outside the insulating layer and cable cover(ing) of branch cable
Surface is coated with hot melt adhesive layer, and plug socket is equipped with the side of leader cable, and plug socket connects leader cable by one section of transition cable.
Further, it is equipped with flame retardant coating between the leader cable conductor and insulating layer of the leader cable.
Further, it is equipped with flame retardant coating between the branch cable conductor and insulating layer of the branch cable.
Further, the c-type conductor connector is wrapped with glass fibre belt, and waterstop is coated with glass fibre belt.
Further, the conductor of the transition cable is connected by c-type conductor connector with leader cable conductor.
Compared with prior art, the beneficial effects of the present invention are：
1. several plug sockets can be set in leader cable side, when the position of branch cable is due to designing, measuring, installing
It can not meet mounting condition, or increase branch line etc. mistake, or during branch cable failure, plug socket can be used to replace branch line
The installation site of cable or increase branch cable connection, to meet different needs, have ensured the normal operation of branch cable.
2. waterproof action can be played while insulating effect is played, the insulation performance of branch cable is effectively strengthened,
It also prevent the oxidation of conductor because being fully sealed when waterstop coats.
3. hot melt adhesive layer can be close by the insulating layer and cable cover(ing) of leader cable and branch cable and branch connected body
Bond together, being firmly combined with property is good, while sealed reliable, ensures that Inundate Voltage Experiment and soaking insulation resistance are up to standard, reduces
Requirement to processing technology.
Brief description of the drawings
Fig. 1 is the structure diagram of the present invention；
Fig. 2 is the cross-sectional view of c-type conductor connector in the present invention.
Embodiment
With reference to specific embodiments and the drawings, the present invention is further illustrated.
As depicted in figs. 1 and 2, a kind of prefabricated branch cable, including leader cable 1 and the branch line for being connected to 1 side of leader cable
Cable 2, the junction injection molding branch connected body 3 of leader cable 1 and branch cable 2.The leader cable 1 includes leader cable conductor
4, flame retardant coating 5, insulating layer 6 and cable cover(ing) 7 are set gradually outside leader cable conductor 4.Branch cable 2 includes branch cable conductor 8,
Flame retardant coating 5, insulating layer 6 and cable cover(ing) 7 are set gradually outside branch cable conductor 8；Leader cable conductor 4 and branch cable conductor 8 it
Between using c-type conductor connector connection 9.The insulating layer 6 and cable of leader cable 1 and branch cable 2 in branch's connected body 3
