Contact wire of the present utility model and termination fitting for catenary, comprise tapered sleeve, is furnished with the tubular chock mutually with the taper hole on the tapered sleeve, vertically be provided with at least two openings on the chock sidewall, a wherein end of described opening is opened to the end of chock and is formed gap, the other end at opening leaves connection side, the gap direction of adjacent opening is opposite, it is characterized in that: described tapered sleeve places in the wire clip body, wire clip body is made of biside plate, one end of side plate is provided with the hole and cooperates with tie bolt, and the other end biside plate of wire clip body is connected as a single entity and is provided with the line hole.
Contact wire of the present utility model and termination fitting for catenary, the side that the coupling end of wherein said wire clip body is positioned at side plate is connected to stiffened edge.
Contact wire of the present utility model and termination fitting for catenary are processed with annular tooth on the endoporus sidewall of wherein said chock.
Contact wire of the present utility model and termination fitting for catenary, the rectangular triangle of wherein said annular tooth also is provided with in the endoporus sidewall equal intervals of chock.
Contact wire of the present utility model and termination fitting for catenary, wherein said wire clip body and tapered sleeve are stainless steel material, and described chock is a bronze material.
Contact wire of the present utility model and termination fitting for catenary, because tapered sleeve places in the wire clip body, wire clip body is made of biside plate, one end of side plate is provided with the hole and cooperates with tie bolt, the other end biside plate of wire clip body is connected as a single entity and is provided with the line hole, wire clip body intensity height in use, good rigidity, non-deformability is strong, be connected to stiffened edge because the coupling end of wire clip body is positioned at the side of side plate, wire clip body and tapered sleeve are stainless steel material, have more increased integral intensity, reduce maintenance time, reduced operating cost; On the endoporus sidewall of chock, be processed with annular tooth, the rectangular triangle of annular tooth has changed common angular thread structure in the prior art, and this device is increased the Clamping force of contact wire or catenary, safety has firmly improved the operational safety performance of electric locomotive.
