Abstract
The invention relates to a multi-core integrated branch cable and a production method thereof. The multi-core integrated branch cable comprises a main cable, branch cables, connecting fixtures and the like, wherein the main cable or each branch cable is formed by twisting 2 to 5 insulated conductors into a core wire, winding, coating and binding the core wire by bags into a cable core, and coating a layer of plastic outer sheath on the cable core through extrusion; the main cable is provided with phase conductor openings connected with terminations of the branch cables; the phase conductor openings are staggered at equal intervals in turn; copper conductors of the terminations of the branch cables with the same phase are in crimp connection with copper conductors at the phase conductor openings of the main cable into a branch connecting body through the connecting fixtures and a compression mould; the crimp connection part is coated with an ethylene propylene rubber self-adhesive tape which is coated with a cross-linked polythene insulation layer; and a sheath of the branch connecting body is moulded on the insulation layer. The multi-core integrated branch cable has a reasonable and compact structure, realizes that a single cable replaces four or five single core cables for use, and has simple laying and small occupied space.
Description
Technical field
The present invention relates to the structure of a kind of branch cable, particularly multi-core integrated branch cable, belong to the cable technology field.
Background technology
Branch cable is from the emanant wiring system differentiation of routine and next, be a kind of efficient, safety, distribution system easily, originate from the eighties at first, use extensively in building trade now, develop also very fast,, develop into important building fields such as present civil building on the middle and senior level, bridge, tunnel, light rail, subway, large-scale style venue from single civil buildings distribution.The reason that branch cable can be rapidly developed mainly is because its tree-like characteristics and prefabrication Stability Analysis of Structures of joining a little.Divide from function, branch cable develops into flame retardant type (dividing category-A, category-B, C class), fire safe type, low smoke and zero halogen clean type from plain edition.Divide from structure, can be divided into single core pattern, the stranded type of single core.Use branch cable very extensive though produce, the structure of use mainly is single core pattern, and also having part is single core coil buckling type (stranded type), does not have the multi-core integrated branch cable structure, can not satisfy the engineering that the cable installing space is little, installation difficulty is big.
Summary of the invention
Purpose of the present invention is exactly for satisfying the demand in market, a kind of multi-core integrated branch cable and production method thereof being provided.
The object of the present invention is achieved like this, multi-core integrated branch cable, comprise main cable, branch cable and multi-core type branch union body, it is characterized in that described main cable or branch cable thoroughly do away with the edge core by 2～5 and be twisted into heart yearn, on heart yearn with the wrapped cable core that is bundled into of bag, the oversheath that extrudes one deck plastics again on cable core constitutes, main cable is provided with the separate core opening that is connected with the branch cable termination, separate core opening equidistantly staggers, the identical separate branch cable termination copper conductor and the copper conductor of the separate core opening part of main cable link together by jockey and crimp crimping, at the position parcel ethylene-propylene rubber self-adhesive tape that the jockey crimping connects, the crosslinked polyetylene insulated layer of parcel on the ethylene-propylene rubber self-adhesive tape, molded injection moulding branch union body sheath on insulating barrier, branch's union body sheath and main cable and branch cable oversheath are coupled to one.
Described insulated wire cores is extruded crosslinked polyetylene insulated layer and is constituted by the fire-resistant mica of wrapped bilayer on the stranded conductor that forms of copper single line that meets the GB/T3953 regulation on fire-resistant mica lapping layer.
Be provided with the PP gasket for packing in the slit of the insulated wire cores in the described cable core.
Described bag is high flame retardant band or nonwoven fabrics.
The manufacture method of above-mentioned multi-core integrated branch cable comprises the steps:
(1) adopt the copper single line that meets the GB/T3953 regulation to be twisted into the conductor of main cable, branch cable;
(2) synthetic mica tape that wrapped bilayer has the high-temperature resistant performance on conductor, the rate of putting up are 50%～60%;
(3) on synthetic mica tape, extrude crosslinked polyetylene insulated layer and constitute insulated wire cores;
(4) adopt 2～5 to thoroughly do away with the edge core, laying up pitch and uniform twisting resistance according to standard, twist together into heart yearn regularly, in the slit of insulated wire cores, adopt the PP gasket for packing to tamp, on heart yearn, adopt high flame retardant band or the wrapped formation cable core of tying up of nonwoven fabrics, on cable core, extrude the polyvinyl chloride oversheath and constitute main cable or branch cable;
(5) separate core opening is set on the main cable insulated wire cores, removes insulating barrier, mica tape, exposed core copper conductor, every kind of separate core opening should stagger equidistantly successively, and A/F should be the jockey width and adds 4～8mm; Remove insulating barrier, mica tape on the certain-length that is fit to the jockey clamping at an end of branch cable, exposed core copper conductor, the copper conductor of identical separate branch line copper conductor and main cable core and together, carry out molded crimping by jockey and crimp, the copper conductor core crimping of main cable and branch cable is linked together;
(6) at the crimping connecting portion of jockey, earlier with ethylene-propylene rubber self-adhesive tape parcel crimping part, be wrapped on the ethylene-propylene rubber self-adhesive tape with crosslinked polyethylene insulation material again, the part that whole crimping is wrapped up is put into mould and is carried out the molded multi-core integrated type branch union body that is injection molded at last, makes multi-core integrated branch cable.
Main cable of the present invention and branch cable partly adopt multi-core integrated structure, and the one-tenth cable core pitch that the standardization stranding comes out is identical, even, and the core of whole cable is the helicoidal structure of standard, can guarantee that the electric field of whole cable, magnetic field are even.In shape, multi-core integrated branch cable is one whole cable, has comprised many cores in the whole cable, can realize three-phase five-wire mode, three-phase four-wire system and individual event outlet in a cable.The several threads core is separate by the insulation color differentiating, and is easily simple, convenient installation wiring.
The structure of branch's union body part and the structure of single core pattern branch cable are essentially different, has only a jockey in branch's union body of single core pattern branch cable, and in the multi-core integrated type branch union body 3～5 jockeies are arranged, carrying out 3～5 crimping connects, form several little union bodies, do not contact mutually between several little union bodies, do not disturb mutually.
Multi-core integrated branch cable can realize that unit cable replaces four or five single-core cables to use, and on overall appearance, it is succinct to many a drop cable installation than single core, installs to take up room for a short time, and winding displacement is clear not disorderly.
