Utility model content
This utility model provides a kind of cable connector structure, needs to use at the scene, with what solve to exist in prior art, the technical problem that cable branch box floor space is big, operation maintenance amount is big.
The technical scheme of cable connector structure provided by the utility model is: a kind of cable connector structure, including at least two cables being respectively provided with wiring section, the wiring section of all cables is respectively provided with the bare exposed conductor being conductively connected according to phase sequence correspondence, the place's of being conductively connected cast cured explosive that the bare exposed conductor of the wiring section of all cables is conductively connected have fully wrapped around described in be conductively connected the solid insulation sheath at place.
The wiring section of all cables is the wiring section divesting oversheath, and described solid insulation sheath extends on the oversheath outside the corresponding wiring section of all cables along the bearing of trend of each cable.
All cables include at least one main loop cabling and at least one duplexure cable, and the wiring section of main loop cabling 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 are respectively provided with biphase above heart yearn, the bare exposed conductor of each phase heart yearn of the wiring section of main loop cabling and duplexure cable to be conductively connected place spaced apart successively along main loop cabling bearing of trend.
The bare exposed conductor of all cables respectively through crimping armor clamp conductive crimp be assembled together realize all cables and be conductively connected according to phase sequence.
The beneficial effects of the utility model are: in cable connector structure provided by the utility model; the bare exposed conductor of the wiring section of all cables is conductively connected according to phase sequence correspondence; the fully wrapped around solid insulation sheath being conductively connected place of this place's of being conductively connected cast cured explosive; by solid insulation sheath to form the insulation protection structure of bare exposed conductor; ensure on the one hand to be effectively conductively connected, also ensure effective insulation protection on the other hand.This cable connector structure can make at the scene; both the skinning operations of cable to be connected can have been carried out at the scene; by the bare exposed conductor of all cables to be connected according to corresponding being electrically connected together of phase sequence; then casting mold is utilized to be conductively connected cast liquid megohmite insulant everywhere; solid insulation sheath is formed, to realize the solid to all cable junctions and insulation protection after it solidifies.Not only can ensure effective connection of main loop cabling and duplexure circuit, and, flexibly and easily, the size of the position being conductively connected place and solid insulation sheath can be adjusted according to actual needs, efficiently solve conventional low pressure pre-branched cable due to the cycle needing prefabrication to cause long, investment height, the problem of site operation difficulty, simultaneously, also efficiently solve and adopt the feeder pillar floor space that feeder pillar exists when realizing branch connection big in the past, joint easily loosens, the problem that operation maintenance amount is big, simultaneously, it also avoid main loop cabling and duplexure cable when adopting feeder pillar and fastened the contact heating realizing electrical connection and easily occur by bus bar and bolt, the problem that there is disaster hidden-trouble.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of cable connector structure provided by the utility model.
Detailed description of the invention
nullAs shown in Figure 1,A kind of embodiment of cable connector structure,Joint design in this embodiment includes two cables being respectively provided with wiring section,These two cables are a main loop cabling 1 and a duplexure cable 2,Wherein,The wiring section 11 of main loop cabling 1 is arranged on the middle part of main loop cabling 1,The wiring section 21 of duplexure cable 2 is arranged on one end of duplexure cable 2,Main loop cabling 1 is respectively provided with the wiring section of duplexure cable 2 according to the corresponding bare exposed conductor being conductively connected of phase sequence,The bare exposed conductor of the bare exposed conductor of each phase on main loop cabling 1 and each phase on duplexure cable 2 is assembled together by crimping armor clamp 4 conductive crimp,The place's of being conductively connected cast cured explosive that the bare exposed conductor of the bare exposed conductor of main loop cabling 1 and duplexure cable 2 is conductively connected has the fully wrapped around above-mentioned solid insulation sheath 3 being conductively connected place.In the present embodiment, the wiring section of two cables is the wiring section divesting cable jacket, and for ensureing the effect of insulation parcel, solid insulation sheath 3 extends on the oversheath outside the corresponding wiring section of two cables along the bearing of trend of each cable.
