Technical field
It the utility model is related to a kind of cable branch T and connect case, especially a kind of company of architectural electricity vertical shaft inner cable branch
Device is connect, belongs to the renovation technique of cable branch T binding structures.
Background technology
The power consumption of present building be it is increasing, for hold current-carrying cable quantity and size be also before institute not
Some increases, the electrical equipment of the interior installation of architectural electricity vertical shaft is also more and more, and this causes each electric shaft needs to take more
Big construction area.Connection and branch piece in electric shaft for cable are the rings of most generally existing in electric low-voltage power supply
Section.It is a big Li Chu for electric shaft and construction and installation personnel if the size of its connecting elements and again convenient construction can be optimized.
Mainly there are cable T joint, plug type bus duct in low-voltage power supply by way of most at present, pre-branched cable, wear
Pierce four kinds of wire clamp.But the place of these four modes all Shortcomings：
Cable T joint：Need to set T to connect case in bifurcation, and main cable need to be blocked, if executive information systems,
Then it is intended to block main cable layer by layer.And main cable connects in T and connected in case by copper bus-bar, five copper bus-bars are side by side
Arrangement needs to take larger space.There is construction trouble in this mode and T connects the problem of box body is big.
Plug type bus duct：It is generally used for conveying the trunk loop of high current, and cost is high.Bus is set at busbar branches
Jack box, bus plugging box equally exist the problem of box volume is big.
Pre-branched cable：Space-consuming is minimum, but pre- branch is before manufacturing, need to actually measure architectural shaft size,
The reprocessing of the position of story height and branch junction makes production, and has immutableness after producing.Such as need to change branch cable
Capacity and length, then to scrap whole piece cable and be made again to producer.
Penetrating cable clamp：Its cabled manner is that several acupuncture points are connected by upper and lower ends, contact cable be present
The problem of area is small, and compress mode and there was only a stud, if leader cable differs with branch cable sectional area, it is also easy to produce
Unreal virtual connection situation is crimped, causes cable temperature rise too high.High-rise building power supply mode is also without the widely used product at present.
The content of the invention
The purpose of this utility model is to consider the deficiency for making up above-mentioned each cable distribution mode and provide a kind of cable T joint
Structure.The utility model solves common cable T and connect and needs to block main cable and construction is cumbersome, plug type bus duct cost is high
And volume is big, pre-branched cable by place to use and restriction of production, the easy virtual connection of penetrating cable clamp and the defects of produce heating etc., this reality
Optimized with new from volume and that reduces electric shaft uses space, and can conveniently and efficiently more for the needs of dilatation in the future
Change branch cable size.
The technical solution of the utility model is：Cable branch T binding structures of the present utility model, include main cable, divide
Branch cable, fixed support, cable clamp, cable T joint guard box, the lower end and upper end of cable T joint guard box are equipped with convenient electricity

Drawn from the through hole of the upper end of cable T joint guard box, the upper and lower ends of main cable are fixed on fixed support by cable clamp
On, one end of branch cable enters casing by the through hole of cable T joint guard box lower end, and the another of branch cable is connected to electrically
Distribution box in vertical shaft.
The utility model, which uses, includes insulated copper parallel groove clamp, main cable, branch cable, fixed support, guard box
The structure of body.Main cable enters protection casing from protection casing lower end, and is drawn from protection casing upper end, in guard box body
Reserved certain length cable simultaneously removes outermost layer sheath protective layer, expose five core ribbon have insulation protection conductive copper wire core and by its
Upper and lower ends are fixed on fixed support, and appropriate spacing is kept per core conductive copper wire core.In insulated copper parallel groove clamp to be installed
Opening position remove conductive copper wire core insulating barrier, the end branch's conductive copper wire core for equally having removed insulating protective layer is passed through
Insulated copper parallel groove clamp connects.Insulated copper parallel groove clamp is entirely copper conductor, and tape insulation protective cover.Branch cable, master
Dry each conductive copper wire core of cable contacts with insulated copper parallel groove clamp face, and is tightened by screw compacting, ensures that three is conductive even
It is logical.Branch cable leads to the corresponding distribution box of floor from protection casing lower end.The utility model compared with prior art, have with
Lower beneficial effect：
1）The utility model does not have to block main cable；
2）The utility model insulated copper parallel groove clamp is compacted using screw tightening, simple to operate and easy construction, from difference
The insulated copper parallel groove clamp of model can branch out the branch cable of different cross section, dilatation in the future can be changed conveniently and efficiently point
Branch cable size；
3）Each conductive copper wire core of the utility model branch cable, main cable contacts with insulated copper parallel groove clamp face, protects
Heating too high phenomenon is not easily caused while demonstrate,proving conductive；
4）The utility model protects casing small volume, can be installed with cable testing bridge close neighbour.
The utility model optimizes from volume and reduces the use space of electric shaft, and needs energy for dilatation in the future
Branch cable size is conveniently and efficiently changed, is a kind of reasonable in design, convenient and practical cable branch T connects case.
