Abstract
The low-impedance steel rail lead-connection wire connector includes plug nail, and is characterized by that the described plug nail is made into the form of ladder, and the upper and lower ladder surfaces of the plug nail are respectively equipped with screw threads, and on the upper ladder surface of the plug nail two stainless steel spring washers and stainless steel fixing nuts are successively set, and on the lower ladder surface of the plug nail two brass nickel-plated flat gaskets, lead-in wire connector or tuning capacitor lead-in wire connector, brass nickel-plated flat gasket, stainless steel fastening nut and stainless steel locknut are successively set. The advantage is that area of contact is big, and electrical contact performance is good, contact performance is stable, and the chock pin can not produce structural deformation, and is difficult for the rupture in the use, and the construction tool is simple, easily construction, and the operator grasps easily, and the operation technology requirement is lower relatively, and the chock pin is dismantled the spoilage and is low, the rate of reuse is high, and the resistance value is little, the rate of change is little.
Description
Technical field
The utility model is particularly related to a kind of rail low resistance and connects the line connecting device.
Background technology
At present, railway rail connects line with signal and is connected by plug pin, and existing plug pin adds the expansion type plug pin for straight plug.Under the condition of the strict processes of factory, the closed contact area that straight plug adds expansion type plug pin and rail is about 30 percent, and the electrical contact performance that causes straight plug to add the expansion type plug pin is poor.In addition, China's rail progressively adopts the PD3 rare earth steel from the nineties later stage, under Chinese Railway railway roadbed condition, the rail elastic deformation is violent, straight plug adds the expansion type plug pin with recurring structure deformation, cause the area of contact of plug pin and rail constantly to descend, influence electrical contact performance, and plug pin fractures easily.
Summary of the invention
The purpose of this utility model is to solve the problems referred to above that prior art exists, provide a kind of area of contact big, electrical contact performance is good, plug pin can recurring structure deformation, and contact performance is stable, impedance is little, and in the use not the rail low resistance of frangibility connect the line connecting device.
The utility model is achieved in that it has a plug pin, its special character is that said plug pin is stepped and is processed with screw thread on the upper and lower cascaded surface of plug pin, on cascaded surface on the plug pin, be disposed with two stainless steel spring packing rings, corrosion-resistant steel captive nut, on the downstairs face of plug pin, be disposed with brass nickel plating flat shim, service conductor joint or tuning capacitor fixture wire joint, brass nickel plating flat shim, corrosion-resistant steel clamp nut and corrosion-resistant steel black nut.
The utility model has the advantages that: owing to be stepped and be processed with screw thread at the plug pin outside face at plug pin, and pass through clamp nut, spring washer, pad is fastened on the service conductor joint on the plug pin, at captive nut, plug pin, under the combined action of spring washer and clamp nut spring, plug pin can not produce cross travel, make this track bond connecting device electrical contact performance good, contact performance is stable, plug pin can not produce structural deformation, and frangibility not in use, service tool is simple, be easy to construction, the operator grasps easily, and operation technological requirement is relatively low, the removing damaged rate of plug pin is low, the repeat usage height, resistance value is little, rate of change is little.

The specific embodiment
Embodiment 1:
As shown in figures 1 and 3, the utility model has a corrosion-resistant steel plug pin 1, said plug pin 1 is stepped and on plug pin 1, be processed with screw thread on the downstairs face, on cascaded surface on the plug pin 1, be respectively installed with two stainless steel spring packing rings 2,3, on the right side of stainless steel spring packing ring 3 corrosion-resistant steel captive nut 4 is installed, on the downstairs face of plug pin 1, be set with service conductor joint 6, be placed with brass nickel plating flat shim 5 respectively in the both sides of service conductor joint 6,7, corrosion-resistant steel clamp nut 8 and corrosion-resistant steel black nut 9 are installed in the right side of corresponding brass nickel plating flat shim 7 on the downstairs face of plug pin 1, are used to prevent that corrosion-resistant steel clamp nut 8 from coming off after long-time vibrations.
During actual installation, bore two mounting holes and mounting hole is carried out tapping at the web of the rail place of rail 10, spring washer 2 is enclosed within on the plug pin 1, screw in laterally and tighten from rail 10 inboards, again spring washer 3, captive nut 4 are installed on the plug pin 1 successively, plug pin 1 is fixed on the rail 10, flat shim 5, service conductor joint 6, flat shim 7, clamp nut 8 and black nut 9 are installed in successively on the downstairs face of plug pin 1, service conductor is linked to each other with service conductor joint 6, by service conductor rail jig, service conductor is fixed on the rail 10.
Embodiment 2:
As shown in Figures 2 and 3, the utility model has a corrosion-resistant steel plug pin 1, said plug pin 1 is stepped and on plug pin 1, be processed with screw thread on the downstairs face, on cascaded surface on the plug pin 1, be respectively installed with two stainless steel spring packing rings 2,3, on the right side of spring washer 3 corrosion-resistant steel captive nut 4 is installed, on the downstairs face of plug pin 1, be set with tuning capacitor fixture wire joint 6`, both sides at tuning capacitor fixture wire joint 6` are placed with brass nickel plating flat shim 5 respectively, 7, corrosion-resistant steel clamp nut 8 and corrosion-resistant steel black nut 9 are installed in the right side of corresponding brass nickel plating flat shim 7 on the downstairs face of plug pin 1, are used to prevent that corrosion-resistant steel clamp nut 8 from coming off after long-time vibrations.
Installation process is with embodiment 1.
