Abstract
The utility model discloses a branch cable. The branch cable comprises a main cable and a branch line cable which are connected through a connector, a connection portion of the main cable and the branch line cable is provided with a heat insulation connection winding cladding layer which is externally provided with a sheath layer, and the heat insulation connection winding cladding layer is formed by winding heat insulation connection material winding cladding belt. According to the branch cable, an expensive large-scale injection machine set and a die which are employed in the prior art are not required for the branch cable, so production cost is reduced, moreover, safety and reliability are both improved.
Description
Technical field
The utility model relates to the power cable field, relates in particular to a kind of branch cable.
Background technology
Branch cable multiplex in skyscraper as for, the master of distribution, trunk cable.It structurally can be divided into 3 parts: main cable, branch cable and branch's connector.Branch cable generally is by the prefabrication moulding, requires to make according to corresponding size according to mapping, main cable is connected with branch cable conductor dbus is crossed copper or the copper alloy compression connects, and carries out complete insulation processing.It is very high that but this mode causes mapping to require, in case a certain data are made mistakes, may cause accumulated error, when error appears in data, could find when generally only having on-the-spot the installation, and can't change after producing, in case occur changing, must rearrange production.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of branch cable that can install at the scene, has solved and must assemble in producer, in case the problem of makeing mistakes and can't remedy.
A kind of branch cable comprises leader cable and branch cable, and both link to each other by connector, lead, the junction of branch cable is provided with heat and fuses lapping layer, and restrictive coating is set outside heat fuses lapping layer again.It is that heat fuses the material twining package tape and is entwined that heat fuses lapping layer.
The utility model adopts hot-melting material to make twining package tape, fuses wrapped whole being bonded together of sealing of crosslinked polyetylene insulated layer with leader cable and branch cable by heat, does not mix mutually and do not continue the wrapped pvc sheath belt that comes up with skin.After finishing said procedure, adopt coal gas that wrapped place heat, can stop when temperature is risen to the insulation that can make inside the lapping layer and sheath material melting, lower the temperature, process.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, has also strengthened the security reliability of branch cable.
Description of drawings
Fig. 1 is 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 to fuse the material twining package tape with the suitable heat of former cable and be entwined heat and fuse lapping layer 3, heat fuses lapping layer 3 outside, twine successively again the formation restrictive coatings such as high-temperature resistance plastice band, soft copper band.By heating to realize that heat fuses the bond vitrified of lapping layer 3 materials, so that branch cable 4 is combined closely with leader cable 1.
The utility model discloses a kind of thinking of novel 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; the identical function that just can reach and effect all belong to protection range of the present utility model.
Claims (2)
1. branch cable, comprise leader cable (1) and branch cable (4), both link to each other by connector (2), it is characterized in that lead, the junction of branch cable (1,4) is provided with heat and fuses lapping layer (3), outside heat fuses lapping layer (3) restrictive coating is set again.
2. branch cable according to claim 1 is characterized in that, heat fuses lapping layer (3) and is entwined for heat fuses the material twining package tape.
