Abstract
The invention discloses a prefabricated branch cable for coal mine, which mainly consists of a main cable, a branch cable, and a branch connecting body connected with the two cables, wherein the main cable and the branch cable respectively structurally comprise a conductor in the middle, and an insulation layer and a protective sleeve layer, which are sequentially coated outside the conductor, the branch connecting body is internally provided with a connecting joint for connecting the conductor of the main cable with the conductor of the branch cable, a protective sleeve is wound at the joint after the connecting joint is connected in a pressing way, and the connecting joint is connected with the protective sleeve layers of the main cable and the branch cable in an overlapping way. The prefabricated branch cable is a rubber sleeve prefabricated branch cable for the coal mine, which is high in safety performance and insulation performance, good in electric performance, and low in construction cost.
Description
Technical field
The present invention relates to the electric wire field, be meant 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 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, to 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 big, the cycle is long, and power supply safety, reliability property are low.
Summary of the invention
The technical problem that the present invention will solve 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 of the present invention; It is made up of leader cable, branch cable and branch's connector of being connected aforementioned two cables; The structure of leader cable and branch cable comprises middle conductor and is coated on conductor outer insulating barrier and restrictive coating successively; Be provided with the jointing that leader cable conductor and branch cable conductor are linked together in branch's connector, after the said jointing crimping in the joint wrapped oversheath, and overlap with the restrictive coating of leader cable, branch cable.
Said branch connector, jointing adopt the oblate copper connector of the annealing of high conduction performance.
It is stranded the forming of annealed copper line of TR that said conductor adopts the multiply code name.
Described insulating barrier adopts thermoplastic rubber's pipe.
The material that said restrictive coating, oversheath adopt is the thermoplastic rubber protective cover material.
Beneficial effect of the present invention is:
The present invention is because after the jointing crimping in branch's connector; Along the wrapped again one deck oversheath of whole jointing outer surface; The restrictive coating of this oversheath and leader cable, branch cable overlaps; So form the outer jacket of an integral body, improved insulation property, the security performance of branch cable greatly, also do not influence the electrical property of branch cable simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment:
As shown in Figure 1; It is made up 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 middle conductor 4 and is coated on the insulating barrier 5 and restrictive coating 6 outside the conductor 4 successively; 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 said 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 process: will divest insulating barrier 5 and restrictive coating 6 according to the site operation size as leader cable 1 conductor of conductor earlier; Insulation gap is no less than 3cm; On head, divest insulating barrier 5 and restrictive coating 6 to branch cable 2 conductors according to concrete length again as conductor; Carry out the branch joint connector through the oblate copper connector of the annealing of high conduction performance then, 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 through notes rubber machine and particular manufacturing craft at last with specialty.
The objective of the invention is to realize like this: leader cable 1 links into an integrated entity through branch's connector 3 with branch cable 2; Branch's connector 3 adopts the oblate copper connector of the annealing of high conduction performance; Be interrupted closed peeling, crimping; Have excellent waterproof, protection against the tide, anti-dust performance; Avoided joint contact position copper core to expose the generation that in air, produces oxidation and cause short circuit between contact resistance increase and cable core simultaneously, such being provided with 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 superior to original rubber-covered; After the branch joint connection completes, produce and make, make master, the original external sheath layer of branch cable effectively be bonded to an integral body with the production equipment (annotating the rubber machine) and the various particular manufacturing craft of specialty; The security performance of cable is better, and the scope of application is wider.
The invention provides a kind of prefabricated branched structure form and implementation method; The above only is a preferred implementation method of the present invention; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; Can also make some improvement, these improvement also should be regarded as protection scope of the present invention.
