Abstract
The utility model discloses a multicore integrated branch cable which consists of a main cable, a branch cable and a connecting clamp, wherein the main cable or the branch cable is twisted to a core wire by 2-5 insulated conductors; a cable core is formed by winding and tying with a bag on the core wire; the cable core is extruded with a layer of plastic outer sheath; the main cable is provided with phase-identifying core openings which are connected with the branch cable end; the phase-identifying core openings are sequentially staggered with equal distance; copper conductors at the same phase-identifying branch cable ends are crimped and connected with copper conductors at the phase-identifying core openings of the main cable through the connecting clamp and a crimping mold to form a branch connecting body; an EPR (ethylene propylene rubber) self-adhesive tape is wrapped at the crimping and connecting part; a crosslinked polyethylene insulating layer is wrapped on the EPR self-adhesive tape; and a branch connecting body sheath is formed on the insulating layer by injection molding. The multicore integrated branch cable has rational and compact structure, can realize a single cable replacing for four or five single-core cables, and has concise cable laying and small occupied space.
Description
Technical field
The utility model relates to the structure of a kind of branch cable, particularly multi-core integrated branch cable, belongs 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.
The utility model content
The purpose of this utility model is exactly for satisfying the demand in market, a kind of multi-core integrated branch cable being provided.
The purpose of this utility model is to realize 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.
Main cable of the present utility model 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.
Description of drawings
Fig. 1 is the structural representation at the union body position of multi-core integrated branch cable of the present utility model;
Fig. 2 is the cross-sectional view at the union body position of multi-core integrated branch cable of the present utility model;
Among the figure: 1 conductor, 2 mica tapes, 3 insulating barriers, 4 gasket for packings, 5 bands, 6 oversheaths, 7 sheaths, 8 jockeies.
Embodiment
1, adopt the copper single line that meets the GB/T3953 regulation to be twisted into the conductor 1 of main cable, branch cable, conductor wire core meets the requirement of 2 class conductors among the GB/3956, has guaranteed that product has excellent conducting performance and pliability.
2, the synthetic mica tape 2 (or claiming fire-resistant isinglass belt) that wrapped bilayer has the high-temperature resistant performance on conductor 1, the rate of putting up is 50%～60%, anti-1000 ℃ temperature.
3, on synthetic mica tape, extrude crosslinked polyetylene insulated layer 3 and constitute insulated wire cores.Use crosslinked polyethylene as cable insulation material, have better dielectric strength and heat-resistant stability than PVC.
