Cable is in the utilization of reality, because the circuit of skyscraper is intricate, then often need branch cable to be used as trunk cable and carry out transmission work, usual branch cable adopts Press Plier to crimp when carrying out branch's connection usually, connect by the mode of crimping and there will be gap, connect effect bad, and junction easily departs from, impact transmits work normally.
Utility model content
The purpose of this utility model is to provide the prefabricated branch cable that can connect firm, that message transmission effect is good a kind of firm connecting-type.
For achieving the above object, the technical solution of the utility model is to provide a kind of prefabricated branch cable of firm connecting-type, comprise leader cable, divide cable, be located at the leader cable core in leader cable, be located at point cable core in point cable, leader cable core is intertwined and connected in the shape of a spiral with a point cable core, the insulating barrier of junction comprises three kinds of material layers, is mica tape, insulating tape, polyethylene from the inside to the outside respectively.
In technique scheme, leader cable core is intertwined and connected in the shape of a spiral with a point cable core, is connected by the mode be mutually helically wound around, leader cable core can be made to be wound around evenly with a point cable core, difficult drop-off, and the joint formed is elegant in appearance, joint connects evenly, is beneficial to the parcel of insulating barrier.The insulating barrier of junction comprises three kinds of material layers, mica tape, insulating tape, polyethylene from the inside to the outside respectively, mica tape is refractory material, the resistance to fire action of cable can be ensured, insulating tape not only insulate, and high temperature resistant, and polyethylene can play the effect of insulation, trilaminate material wraps up the insulating barrier obtained, and ensure that branch cable insulate in the junction of branch, high temperature resistant, fire-resistant good nature.
The mode that the utility model is wound around by leader cable core and point cable core mutually in bifurcation is connected, connect firm difficult drop-off, and be rich in attractive in appearance, be beneficial to the parcel of insulating barrier, insulating barrier is consisted of mica tape, insulating tape, polyethylene trilaminate material, allows branch cable have good fire-resistant, high temperature resistant, insulation property.The utility model is by manual hand manipulation, and bifurcation leader cable core is wound around evenly with a point cable core, and Connected degree is good, there will not be substandard products phenomenon, is conducive to message transmission, ensures the quality of branch cable.
Further, the spiral number of turns after described leader cable core and point cable core spiral wound is 4 to 6 enclose, and the number of turns of 4 to 6 circles are just right, both ensure that the fixing of connection, can not waste cable more again, wasting process time because being wrapped over.
Further, be provided with many leader cable cores in described leader cable, a point cable is provided with many point cables core, and the number of leader cable core and one_to_one corresponding spiral winding equal with dividing cable core number connects.This mode be intertwined and connected also is applicable to the connection between the cable of many inner cores, as long as leader cable core number is equal with point cable core number, can by the color of leader cable in-core respectively with each color matching of point cable core, just leader cable core can be connected according to identical color one_to_one corresponding spiral winding with a point cable core, form branch cable.
Further, described leader cable is connected with multiple points of cables, forms multi-way cable, leader cable and multiple points of cables is intertwined and connected one by one, forms the multi-way cable of multiple branch by above-mentioned mode.
