The place's of being conductively connected cast that the bare exposed conductor of the wiring section of all cables is conductively connected is solidified with fully wrapped around described be conductively connected
The solid insulation sheath at place.
The wiring section of all cables is to have divested the wiring section of oversheath, solid insulation sheath the prolonging along each cable
Over is that is extended on the oversheath on the outside of the corresponding wiring section of all cables.
All cables include an at least main loop cabling and an at least duplexure cable, the wiring of main loop cabling
Section is arranged at the middle part of main loop cabling, and the wiring section of duplexure cable is arranged at one end of duplexure cable.
Described main loop cabling and duplexure cable is respectively provided with cored wire more than two-phase, main loop cabling and branches back to
The place of being conductively connected of the bare exposed conductor of each phase cored wire of the wiring section of road cable is spaced point successively along main loop cabling bearing of trend
Cloth.
The bare exposed conductor of all cables being assembled together to realize all cables by crimping armor clamp conductive crimp respectively
It is conductively connected according to phase sequence.
The beneficial effects of the invention are as follows：In cable connector structure provided by the present invention, the wiring section of all cables it is naked
Dew conductor is correspondingly conductively connected according to phase sequence, and cast completion of cure parcel in the place of being conductively connected is conductively connected the solid insulation shield at place
Set, by solid insulation sheath to form the insulation protection structure of bare exposed conductor, on the one hand ensure effectively to be conductively connected, it is another
Aspect also ensures effective insulation protection.This cable connector structure can be made at the scene, can both carry out the company for the treatment of at the scene
The skinning operations of cable are connect, the bare exposed conductor of all cables to be connected are electrically connected together according to corresponding to phase sequence, then
Cast liquid megohmite insulant everywhere is being conductively connected using casting mold, solid insulation sheath is being formed after its solidification, to realize
To the solid at all cable connections and insulation protection.It can not only ensure that main loop cabling and the effective of duplexure circuit connect
Connect, moreover, flexibly and easily, the position at place and the size of solid insulation sheath can be conductively connected according to adjustment is actually needed, had
It is high, site operation difficulty that effect solves conventional low pressure pre-branched cable cycle length, investment caused by due to needing prefabrication
Problem, meanwhile, also efficiently solve in the past when realizing branch connection using feeder pillar existing feeder pillar floor space greatly, joint
Easily loosen, the problem of operation maintenance amount is big, meanwhile, main loop cabling and duplexure cable when it also avoid using feeder pillar
The contact for realizing electrical connection by bus bar and bolt fastening easily to occur generates heat, the problem of disaster hidden-trouble be present.
Brief description of the drawings
Fig. 1 is a kind of structural representation of embodiment of cable connector structure provided by the present invention.
Embodiment
As shown in figure 1, a kind of embodiment of cable connector structure, the joint design in the embodiment, which includes having respectively, to be connect
