DEVICE FOR ELECTRIC BUTT-JOINING OF RAILS Russian patent published in 1995 - IPC

FIELD: railway transport. SUBSTANCE: device has current conductor made of multicore, for instance, aluminium wire, two, for instance, aluminium bushings press-fitted in holes of webs of first and second ends of rails in joint, and steel inserts at both sides of fishplate. Insert is made with taper seat surface in range from 1:5 to 1:200. Ratio of yield point of insert material to bushing material is not less than 4.0:1.0 and not greater than 12.5: 1.0. Design of connector makes unnecessary accurate machining of insert seat taper and provides its press-fitting in service. EFFECT: enhanced quality of rail joining. 4 dwg
