Abstract
The utility model discloses a prefabricated branch cable, which consists of a main cable, a sub-branch cable and a branch connecting body by which the main cable is connected with the sub-branch cable, wherein the structure of each of the main cable and the sub-branch cable comprises a conductor in the middle of the structure, and an insulation layer and a sheath layer which sequentially wrap the conductor; a connector by which the conductor of the main cable is connected with the conductor of the sub-branch cable is arranged in the branch connecting body; an outer sheath wraps the connector after the connector is subjected to pressure welding; and the sheath layers of the main cable and the sub-branch cable are lap-jointed with the connector. The rubber sheath prefabricated branch cable for coal mine is good in safety performance, insulating property and electrical property and low in construction cost.
Description
Technical field
The utility model relates to the electric wire field, refers to that specifically a kind of colliery overlaps prefabricated branch cable with rubber.
Background technology
In general the colliery is used in the tunnel with MY type Plastic-sheathed Cable, because illumination, water pump, motor need to connect branch cable, and poor stability under the mine, the electrician carries out not only poor quality of manual wiring, and just in case operate miss causes gas explosion generation mine disaster, so along with the further attention of Safety of Coal Mine Production, as new trend, for the further raising of connection of coal mine roadway inner cable.
And at present, colliery of the prior art is relatively poor with rubber cover prefabricated branch cable insulating properties, and the site operation expense is large, the cycle is long, and power supply safety, reliability are low.
The utility model content
The technical problems to be solved in the utility model provide a kind ofly improve security performance, insulation property, good electrical property, prefabricated branch cable is overlapped with rubber in colliery that construction cost is low.
A kind of prefabricated branch cable described in the utility model, it is connected branch's connector of two cables by leader cable, branch cable and connection and forms, the structure of leader cable and branch cable comprises middle conductor and is coated on successively conductor outer insulating barrier and restrictive coating, be provided with the jointing that leader cable conductor and branch cable conductor are linked together in branch's connector, after the described jointing crimping in the joint wrapped oversheath, and overlap with the restrictive coating of leader cable, branch cable.
It is stranded the forming of annealed copper line of TR that described conductor adopts the multiply code name.
The beneficial effects of the utility model are:
The utility model is because after the jointing crimping in branch's connector, along whole jointing outer surface wrapped one deck oversheath again, the restrictive coating of this oversheath and leader cable, branch cable overlaps, so form the outer jacket of an integral body, greatly improve insulation property, the security performance of branch cable, also do not affected the electrical property of branch cable simultaneously.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment:
As shown in Figure 1, it is comprised of leader cable 1, branch cable 2 and branch's connector 3 of being connected aforementioned two cables, the structure of leader cable 1 and branch cable 2 comprises the conductor 4 of centre and is coated on successively conductor 4 insulating barrier 5 and restrictive coating 6 outward, be provided with the jointing 7 that leader cable 1 conductor and branch cable 2 conductors are linked together in branch's connector 3, after described jointing 7 crimping in the joint wrapped oversheath 8, and overlap with the restrictive coating 6 of leader cable 1, branch cable 2.
Prefabricated branch cable as shown in the figure can adopt following procedure of processing to make: will divest insulating barrier 5 and restrictive coating 6 according to the site operation size as leader cable 1 conductor of conductor first, insulation gap is no less than 3cm, again branch cable 2 conductors as conductor are divested insulating barrier 5 and restrictive coating 6 according to concrete length at head, then carry out the branch joint connector by the oblate copper connector of the annealing of high conduction performance, form the conductor transmission current, adopt thermoplastic rubber's seal of tube tight after the crimping well, form insulating barrier, annotate the outer jacket that rubber forms integral body by notes rubber machine and particular manufacturing craft with specialty at last.
The purpose of this utility model is achieved in that leader cable 1 and branch cable 2 link into an integrated entity by branch's connector 3, branch's connector 3 adopts the oblate copper connector of the annealing of high conduction performance, be interrupted closed peeling, crimping, have good waterproof, protection against the tide, anti-dust performance, avoided simultaneously joint contact position copper core to expose the generation that produces oxidation and cause short circuit between contact resistance increase and cable core in air, such arranging reduced the wiring error that the miner causes when the cable main line connects branch line.Adopt thermoplastic rubber's seal of tube tight after the crimping well, performance is better than original rubber-covered, after the branch joint connection completes, production equipment (annotating the rubber machine) and various particular manufacturing craft with specialty are produced and are made, make master, minute original external sheath layer of cable effectively be bonded to an integral body, the security performance of cable is better, and the scope of application is wider.
The utility model provides a kind of prefabricated branch version and implementation method; the above only is preferred implementation method of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvement, these improvement also should be considered as protection range of the present utility model.
