Abstract
The utility model discloses a cable with branches. The utility model comprises a main trunk line cable, a branch line cable, a supporting piece, a branch connecting body, and an outer insulating protective sleeve, wherein, the main trunk line cable is connected with the branch line cable through the branch connecting body, a branch connecting point is provided with the outer insulating protective sleeve, and the supporting piece is arranged at the upper end of the main trunk line cable. The utility model is characterized in that a hanging hook is used as the main body of the supporting piece; the circle surface of the lower end of the supporting piece is provided with an insulating layer; after circle retracing plying operation is carried out on an inner core of the main trunk line cable, moulding is carried out on the inner core of the main trunk line cable by the branch connecting body; the main trunk line cable is integrated with the branch connecting body through injection moulding by the outer insulating protective sleeve. The top end of the cable bears great force, and the main trunk line cable is reliably connected with the branch line cable.
Description
The utility model relates to a kind of cable.
Existing cable is made up of conductive core line (conductor), insulating protection overcoat and cable fixed mount.In the power transmission and distribution construction of building, each layer electricity consumption end to power supply is all connected by whole cable, leader cable is connected at the construction field (site) with branch cable, engineering time is long, sealing can not guarantee, and cause cable waste and circuit confusion easily, required accessory and the material of cable branch also needs to store in the warehouse of construction site and management in addition, and this has increased construction cost again.In the electrical design of middle-high building, major part adopts bus duct at present, and the on-the-spot installation of bus duct is complicated, and incipient fault point is many, and vibration strength is poor, and the exclusion seal performance is difficult to assurance.The applicant overcomes the defective that above-mentioned technology exists, promptly " Branch shape cable " (ZL98219844.2) to have designed a kind of band branch cable (or claim prefabricated branch cable), the branch cable inner core is connected with vertical main cable inner core with branch's connector, the air-tightness mold pressing is carried out with ambroin in the branch junction, vertical main cable upper end configuration supporting member.Vertical main cable top is bonded on the termination with fire prevention compound, covers the cap that an insulating plastics material is made again, strengthens with heat-shrink tube after installation.Be equipped with geometrical clamp during installation.
Above-mentioned patent is as the prefabricated components in the Structural Engineering, technical indicators such as temperature rise under withstand voltage, impedance, the rated current can be well controlled in advance, removed the job site forked working from, saved the engineering time, and the air-tightness of cable and water resistance are good, the dielectric strength height, vibration strength is good.But the supporting member design of cable upper end is desirable not enough, and holding capacity is not high, and the back is installed strengthens cumbersome with heat-shrink tube.
The purpose of this utility model is, on the basis of above-mentioned patent and overcome the defective that its exists, provides a kind of band branch cable, and cable top holding capacity is big, and the backbone cable is connected reliably with the branch line cable.
For achieving the above object, the solution that the utility model is taked is, a kind of band branch cable, comprise backbone cable, branch line cable, supporting member, branch's connector, insulating protection overcoat, the backbone cable is connected with branch's connector with the branch line cable, and there is the insulating protection overcoat branch junction, backbone cable upper end configuration supporting member, it is characterized in that a hook being arranged, insulating barrier is arranged on its circle surface, lower end as the supporting member main body; The inner core of backbone cable turns back by circle, and plying is back to carry out mold pressing with branch's connector, and the insulating protection overcoat is injection molded into one with backbone cable and branch's connector.
Branch's connector is the O type, adopts silver-plated oxygen-free copper pipe.
The utlity model has following good effect:
1, supporting member of the present utility model is linked up with insulation unlike the prior art, has good air-tightness and water resistance, does not remake air-tightness and water-proofing treatment after need not installing, and has further saved the engineering time.
2, can bear the static weight of self twice after the utility model is hung up, and its supporting member ability alternating voltage 4000V 1min in water does not puncture.
3, branch's connector is very important for the connection reliability of backbone cable and branch line cable.In existing product, all use a kind of C type branch connector.The utility model adopts O type branch connector, and the relatively good grasp of size makes backbone cable and branch line cable be connected firmly closely and don't original intensity of reduction backbone cable and branch line cable after the compacting.
Below in conjunction with embodiment and accompanying drawing thereof the utility model is remake description.
