Abstract
The utility model discloses a prefabricated branch cable, including main cable and branch cable connected with the main cable, a cladding layer is arranged on the connection portion of the main and branch cables, the cladding layer is coiled with 1-3 layers of high temperature resistant plastic belts, 1-2 layers of glass fiber belts and 1-2 layers of soft copper belts in sequence. Insulation and sheath may be made by same material or different material, may be fulfilled once or times without number based on particular conditions. The utility model does not need expensive large-sized injection moulding units and moulds in the existent technology, such that production cost is reduced, and safety and reliability are improved.
Description
Technical field
The utility model relates to a kind of branch cable, relates in particular to a kind of prefabricated branch cable.
Background technology
As everyone knows, branch cable is to utilize connector to link together the conductor of leader cable and the conductor of branch cable in factory, insulating sleeve material after adopting corresponding injection-moulding device with fusion then injects in the supporting mould, thereby finish the manufacturing of branch cable, as described in Chinese patent 03278121.0,98241548.6,200420077772.7,200820065152.X etc.Yet these Technology Needs are bought the mould of large-scale injection moulding unit and all size model to adapt to the manufacturing of various branch cable; Moreover than higher, stability is difficult to control to the requirement of operating technology for it; Need take bigger space and more manpower when making simultaneously, production efficiency also can't improve; In addition, insulation and sheath can't carry out layering to be handled, just insulation and sheath can only disposablely inject, can not adopt two kinds of different materials, YJV type cable for example, the insulating sleeve of its junction can only be crosslinked polyethylene material or a kind of materials such as polyethylene material or polyvinyl chloride material, and can not realize that the insulation identical with original structure is that cross-linked polyethylene insulating material and sheath are 90 ℃ pvc sheathing compound, thereby has a strong impact on the long-term property safe and reliable to operation of cable.
The utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of prefabricated branch cable cheaply is provided, and this cable promptly need not to adopt injection moulding unit and injection mold, can not take very big place again, not need too many manpower, its good quality of product yet, the production efficiency height, easy and simple to handle.
Prefabricated branch cable described in the utility model, comprise leader cable and the branch cable that links to each other with leader cable, lead, the junction of branch cable is provided with material and master, branch cable is identical and the lapping layer that merges by mode of heating, lapping layer is outward more successively around adding high-temperature resistance plastice band, glass fiber tape and layer soft copper band.
Above-mentioned high-temperature resistance plastice band is preferably the 1-3 layer, glass fiber tape is that 1-2 layer and soft copper band are the 1-2 layer.
The insulation that above-mentioned lapping layer thickness is leader cable and the 1.2-1.8 of jacket thickness summation are doubly.And the high-temperature resistance plastice band is the fluoroplastics band.
The utility model adopts the strip material identical with insulation, the sheath material of former leader cable and branch cable to carry out wrapped to the junction that connects later branch cable, it is wrapped that its form is that multilayer is put up, until wrapped thickness be the leader cable insulation with the 1.2-1.8 of jacket thickness summation doubly till.This wherein can adopt separately a kind of material according to situation, also can adopt different materials in the hope of identical with former construction of cable material, and VV type cable for example just can disposable whole wrapped vinyl tapes, until nominal thickness; And YJV type cable, can be earlier wrapped crosslinked polyetylene insulated bring to nominal thickness after, continue wrapped and the suitable polyvinyl chloride band of cable operating temperature thereon until nominal thickness, can realize crosslinked polyetylene insulated layer of bonding together of can all sealing of leader cable and branch cable like this, mix mutually and do not continue the wrapped pvc sheath belt that comes up with skin.
Wrapped good insulation and restrictive coating are outer around adding the resistant to elevated temperatures teflin tape of 1-3 layer, and then continue around adding glass fiber tape 1-2 layer (being determined on a case-by-case basis) with excellent fire-retardancy, need continue at last around adding soft copper band 1-2 layer (being determined on a case-by-case basis) on glass fiber tape, after finishing said procedure, can adopt coal gas or other method that wrapped place is heated, can stop when temperature is risen to the insulation that can make lapping layer the inside and sheath material fusion, lower the temperature, handle.Generally speaking; outmost temperature should the insulation and the sheath material melting temperature on about 30-50 ℃; this is that the thermal resistivity of self has determined the decay of temperature in its heat conduction about 40 ℃ because all material of insulation and sheath material outside all shields and conduction of heat.It is to be noted; if insulating layer material is different with the restrictive coating material, for example YJV type cable just need be divided into two the aforesaid operations program; carry out around adding each layer protection structure after to be that insulating barrier is wrapped finish; heating and melting, itself and former cable insulation are combined together after, carrying out wrapped sheath material; then carry out follow-up same operation; be intended that insulating barrier and restrictive coating are handled respectively, accomplish clear in structure, tight, firm, to guarantee fail safe, the consistency of cable.
The utility model has not only been cancelled the required equipment investment of making branch cable, has reduced the production technology difficulty, has reduced labor cost, has improved production efficiency.Also strengthened the security reliability of branch cable.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
As shown in the figure, product of the present utility model by connector 2 with leader cable 1 with after branch cable 4 is connected, adopt with the suitable strip material of former cable to its wrapped formation lapping layer 3, outside lapping layer 3 more successively around adding 1-3 layer high-temperature resistance plastice band, 1-2 layer glass fiber tape and 1-2 layer soft copper band.Realize the bond vitrified of lapping layer 3 materials by heating, thereby realize excellent sealing performance, electric property and mechanical performance between branch cable 4 and the leader cable 1.
The utility model discloses a kind of thinking of novel prefabricated branch cable; this thinking can also be used in other various different materials and multi-form branch cable; every do not have substantial change to said method of the present utility model; just identical function that can reach and effect all belong to protection range of the present utility model.
