Abstract
The utility model relates to a branch cable, comprising main cables, branch cables, branch connection pieces for connecting the main cables and the branch cables, moulded bodies that are arranged outside of the main cables, the branch cables, and the branch connection pieces through injection mould. The moulded bodies are connected together with the oversheath of the main cables through injection mould, and the branch ends of the moulded bodies are connected together with the oversheath of the branch cables through injection mould. The utility model has the advantages of no site operation, convenient installation, high safety, and good reliability.
Description
The utility model relates to a kind of electric wire.
At present domesticly in the construction of skyscraper, tunnel illumination, resident's building, big capacity office building, hospital etc., often run into the cable branch problem, domestic the most frequently used method is to adopt the aluminium alloy branch joint at present, itself has fastening bolt joint, fastening back external application PVC adhesive tape and heat-shrink tube insulation; Situation for leader cable and branch cable unequal section, clamp again after must twining the branch cable conductor with tinsel, or directly branch conductors is wrapped in (the branch cable conductor is than under the details condition) on the leader cable conductor, almost all work is all finished at the construction field (site), required site operation labour is many, efficiency is low, material and instrument consumption greatly, make field management complicated; Because the limitation of site operation environment and constructor's quality, branch joint and the reliability and the not assurance of fail safe of going up end bearing, and lack effective supervision detection method and equipment, both made under optimal situation, bulky with the branch joint insulation back that these means are made, particularly when multicore cable was told a plurality of branch, its huge workload made the most skilled constructor also feel more headache; In addition, required a large amount of rotating shaft positions of site operation and how to guarantee the air-tightness of branch joint and last end bearing and water proofing property etc. has also proposed an a lot of difficult problem to the constructor.
It is a kind of without site operation, easy for installation and fail safe and the higher branch cable of reliability that the purpose of this utility model is to provide.
The purpose of this utility model is achieved in that the utility model comprises the branch's connector and the moulded body of pressure injection outside leader cable, branch cable and branch's connector of leader cable, branch cable, connection leader cable and branch cable, the oversheath pressure injection of moulded body and leader cable connects as one, and the oversheath pressure injection of the Zhi Duan of moulded body and branch cable connects as one.
Adopt the utility model branch cable, because saved the site operation labour, so total architectural engineering expense comprises that personnel and Master Cost have just compressed greatly.Because on-the-spot most work is all finished in factory, thereby has saved the working time of job site.The branch cable and the last end bearing work that influence this system electrical performance and physical property are all finished in factory, and under strict quality control and works fine environment, carry out, and the project that all branch cables need be checked is also all finished before shipment, the fail safe and the reliability of engineering like this, have greatly been guaranteed.
The utility model branch cable on drum, make on-the-spot easy for installation, so field management work, such as the arrangement of erection schedule, material requested obtain and storage etc. all can be saved.
The branch joint of the utility model branch cable and last end bearing all are airtight and waterproof, so this cable is equally applicable to the humid area.
Accompanying drawing 1 is the utility model structural representation.
Accompanying drawing 2 is the utility model cutaway view.
Accompanying drawing 3 is the practical view of the utility model.
Below in conjunction with accompanying drawing the utility model is described in detail:
Shown in accompanying drawing 1,2,3, the utility model moulded body 3 is PVC moulded body or rubber moulded body.Branch's connector 2 is a metal branch connector, is suppressed with groove 5 on branch's connector 2.Branch's connector 2 is should electric conductivity good, and enough big intensity is arranged again, also as far as possible little volume will be arranged.What power department was used always in the construction of carrying out cable branch is the aluminium alloy branch joint, and the aluminium alloy branch joint does not obviously reach requirement like this, and its electric conductivity and intensity guarantee by its huge volume entirely.Through Theoretical Calculation and test for several times, we have selected the material of the red copper after the annealing as branch's connector 2 for use, and its electric conductivity and plasticity are good, are suitable for cold working, and enough intensity is arranged.In definite branch connector 2 materials, we have also carried out for several times improving to its pressing mold, and newly-designed pressing mold has " U " connected in star 5, make branch's connector 2 of extrusion be easier to combine with conductor and outer PVC moulded body 3 thereof; Compare with the branch connector, PVC moulded body 3 Mould design have bigger difficulty, and PVC moulded body 3 is bonded together with the overcoat of leader cable 1 and the overcoat of branch's connector 2 and branch cable 4; Not only will have the good insulation performance performance, the mechanical and physical performance and the electric property of common cables such as enough tensile strength, percentage elongation also should airtight and waterproof.
