Background technology
Branch cable is factory's cable by user's design drawing prefabricated branch line when producing main cable, be used for connecting the cable of power consumption equipment electric power distribution network, it is a New Product in recent years, at present, branch line factory is manufactured on the main cable in advance, branch line cross-sectional sizes and branch line length etc. are to determine according to designing requirement, if deviation can not occur in the actual project installation process, then can greatly shorten construction period, significantly reduce Master Cost and operating expenses, guaranteed the reliability of distribution largelyr, but in the project installation process of reality, deviation can occur, prefabricated branch cable has been difficult to change position dimension, the easy like this location of causing is inaccurate, produce in addition the deviation of branch cable length and reality in plant design, cause easily the cable waste, improved cost.The people is arranged at present with the insulating barrier strip off of leader cable, and then branch cable received on the leader cable, bundle with insulating tape in the junction at last, so just finished the branch of cable, but branch's moisture resistivity that this method is finished, corrosion resistance, sealing are all poor, and the scope of application is very restricted, and particularly is applied in the cable of hoistway, environment is extremely abominable, is more prone to breaking of cable branch head occurs and causes the security incidents such as electric leakage.Therefore, the cable branch structure of prior art is badly in need of improving.
The utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, provides that a kind of simple in structure, corrosion resistance is strong, good airproof performance, tensile strength reach greatly safe and reliable hoistway electricity consumption branch cables header structure.
The technical scheme that the utility model adopts is: the utility model comprises leader cable, branch cable and splitter box, described branch cable is electrically connected with described cable, the junction of described branch cable and described cable is positioned at described splitter box, be filled with megohmite insulant in the described splitter box, described megohmite insulant covers described junction, and described leader cable and the described branch cable that will be positioned at described splitter box are fixed on described splitter box, so that extraneous moisture can not directly contact with the metal that the junction exposes and corrode.
Described megohmite insulant is made as pitch or insulating resin or electro-insulating rubber, can select concrete megohmite insulant according to the actual application environment of cable.
Described splitter box comprises that box body reaches the lid suitable with described box body, covers described lid again after described box body is filled described megohmite insulant.
Described lid is that buckle is connected with the connected mode of described box body, perhaps is connected to each other by screw, and perhaps the buckle connection is connected to each other combined with screw.
Be provided with described leader cable and the suitable die cavity of described branch cable in the described box body, described megohmite insulant is filled in the described die cavity.
Be provided with in the described splitter box be used to the compressing member that is fixed described leader cable and described branch cable, when described box body and described lid closely cooperate, described lid described compressing member toward pressing down, described leader cable and described branch cable are fixed under the acting in conjunction of described box body and described lid so that described leader cable and described branch cable all with the firm combination of described box body.
The beneficial effects of the utility model are: because the utility model has adopted the design that is filled with megohmite insulant in the described splitter box, the utility model comprises leader cable, branch cable and splitter box, the junction of described branch cable and described cable is positioned at described splitter box, be filled with megohmite insulant in the described splitter box, described megohmite insulant covers described junction, after filling is finished, described leader cable, described branch cable and described splitter box become one, so that extraneous moisture can not directly contact with the metal that the junction exposes and corrode, corrosion resistance is strong, good airproof performance; Also strengthen simultaneously the contact area of described leader cable and described branch cable, improved electric conductivity, also strengthened resistance to tension, so the utility model is simple in structure, tensile strength reaches greatly safe and reliable.

Embodiment
As shown in Figure 1 to Figure 3, in the present embodiment, the utility model comprises leader cable 1, branch cable 2 and splitter box 3, described branch cable 2 is electrically connected with described cable 1, described branch cable 2 is positioned at described splitter box 3 with the junction of described cable 1, be filled with megohmite insulant 4 in the described splitter box 3, described megohmite insulant 4 covers described junction, and described leader cable 1 and the described branch cable 2 that will be positioned at described splitter box 3 are fixed on described splitter box 3.Described megohmite insulant 4 can be made as pitch or other megohmite insulants such as insulating resin or electro-insulating rubber, and in the present embodiment, described megohmite insulant 4 is preferably pitch.
Described splitter box 3 comprise box body 31 and with the suitable lid 32 of described box body 31, after described box body 31 is filled described megohmite insulant 4, cover again described lid 32.
Described lid 32 is that buckle is connected with the connected mode of described box body 31, perhaps be connected to each other by screw, perhaps buckle connects and passes through the interconnected combination of screw, in the present embodiment, described lid 32 and the connected mode of described box body 31 be buckle be connected with by the interconnected combination of screw.
Be provided with the suitable die cavity 33 of described leader cable 1 and described branch cable 2 in the described box body 31, described megohmite insulant 4 is filled in the described die cavity 33, in the present embodiment, inject in the described die cavity 33 after the described asphalt high-temperature melting, after the cooling, described bitumen embedding is in described die cavity 33, thus the formation insulating barrier.
Be provided with in the described splitter box 3 be used to the compressing member 5 that is fixed described leader cable 1 and described branch cable 2, when described box body 31 and described lid 32 closely cooperate, toward pressing down, described leader cable 1 and described branch cable 2 are fixed under the acting in conjunction of described box body 31 and described lid 32 described lid 32 described compressing member 5.
