Abstract
The utility model discloses a kind of the urban transportation parts, specifically a kind of embedding ground formula electric power system connecting box.Comprise box body and the lid for being arranged on box body top, between box body and lid, sealing member is installed, lid is arranged on after on box body and is fixed by fastener, tray interior has for cable laying and the cavity installing conversion terminal, box body rear and front end is provided with the fairlead communicated with cavity, and lid is provided with wear resistant ceramic chip.After adopting above-mentioned structure, the problem of the conversion terminal of the inner installing cables of connecting box can be solved, easily complete the switching of a cable and secondary cable between embedding ground cribbing and switch box, avoid supply cable occur displacement and damage, ensure that the safe and reliable power supply of embedding ground formula contact rail electric power system.
Description
Technical field
The utility model relates to a kind of the urban transportation parts, specifically a kind of embedding ground formula electric power system connecting box.
Background technology
In field of urban rail, traditional power supply mode that electric train adopts mainly contains overhead contact line mode and contact rail power supply mode.Overhead contact line is for being arranged on height apart from rail about 4 ~ 5m eminence along circuit, contact rail is then be arranged on circuit side along circuit, and general about have 200 ~ 400mm apart from ground.Overhead contact line setting height(from bottom) is high, is not easy to maintenance, and has a certain impact to view; Contact rail setting height(from bottom) is low, easy installation and maintenance, and can not impact view, but because contact rail setting height(from bottom) is low, make it may cause personnel's Danger Electric shock risk, therefore track traffic is generally totally enclosed management, and this makes contact rail system have certain selection for the environment be suitable for.
Embedding ground formula contact rail electric power system can solve defect and the restriction of conventional overhead contact system and contact rail system, embedding ground cribbing is directly installed on road surface, contact the upper surface that rail bar is then arranged on embedding ground cribbing, therefore, embedding ground formula contact rail electric power system is easy to build, cost is lower, and does not take space outerpace limited in city, can not affect urban look.But the switch box of embedding ground formula electric power system with there is cable between embedding ground cribbing and be connected; failure-free connection structure is not had to complete the switching of a cable and secondary cable between embedding ground cribbing and switch box in prior art; cable usually can be made thus to occur displacement and damage, have impact on the safe and reliable power supply of embedding ground formula contact rail electric power system.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of rational in infrastructure, easy for installation and can ensure the embedding ground formula electric power system connecting box of the safe and reliable power supply of embedding ground formula contact rail electric power system.
In order to solve the problems of the technologies described above, embedding ground of the present utility model formula electric power system connecting box, comprise box body and the lid for being arranged on box body top, between box body and lid, sealing member is installed, lid is arranged on after on box body and is fixed by fastener, tray interior has for cable laying and the cavity installing conversion terminal, and box body rear and front end is provided with the fairlead communicated with cavity, and lid is provided with wear resistant ceramic chip.
Builtin-nut is provided with in the cavity of described box body.
The base of described box body is provided with locator protrusions.
Described box body and lid are made by glass-reinforced plastic material.
The base of described box body is provided with waterproof joint.
The end, rear and front end of described box body is provided with the protection joint that can dock with the parts of embedding ground cribbing or embedding ground formula electric power system.
After adopting above-mentioned structure, due to the box body with fairlead arranged and the lid be arranged on box body, tray interior is provided with for cable laying and the cavity installing conversion terminal, inside is furnished with builtin-nut, the problem of the conversion terminal of the inner installing cables of connecting box can be solved thus, easily complete the switching of a cable and secondary cable between embedding ground cribbing and switch box, avoid supply cable and occur displacement and damage, ensure that the safe and reliable power supply of embedding ground formula contact rail electric power system; Be provided with locator protrusions bottom box body simultaneously, be convenient to location and installation, between box body and lid, seal ring is installed, lid top is provided with wear plate, make it have water-proof function, box body and lid are made up of glass-reinforced plastic material, make its intensity high and have good insulation and water resistance, the waterproof joint arranged, further ensures the degree of protection of connecting box entirety.
