FIELD: electrified railways.
SUBSTANCE: proposed group of inventions is designed for butt-joining contact wires. According to first version, splicing fitting contains two dies with upper inner support projections, with teeth in lower part, suspended shackle and fastening bolts with locknuts. Cut is made on cavities in dies of splicing fitting to embed it into shackle body at mounting. Shackle is made of material whose electric conductivity exceeds electric conductivity of die material. According to second version, splicing fitting also has two dies with upper inner support projections, with cavity for shackle and projections with teeth in lower part, suspended shackle and bolts with locknuts. Shackle is made with bends. Height of inner part of shackle in straightened out state is not less than length of space between upper inner projections of dies of splicing fitting and ends of contact wires fitted in splicing fitting. Shackle is made of material whose electric conductivity exceeds electric conductivity of die material.
EFFECT: increased electric conductivity of splicing fitting and improved reliability of connection of contact wires.
