A junction part, is connected the middle part of upper grip and lower chuck.
Described clamp assemblies comprises and is arranged on upper clamp structure in upper groove and the corresponding lower clamp structure be arranged in low groove, when described upper grip coordinates with lower chuck, for clamp leads or extinguishing arc rope.
Described upper clamp structure and lower clamp structure are broached-tooth design.
Described upper clamp structure and upper grip are one-body molded; Described lower clamp structure and described lower chuck are one-body molded.
In the middle part that described upper grip is corresponding with lower chuck, offer a connecting hole respectively, link is each passed through the connecting hole of lower chuck and the connecting hole of upper grip, thus upper grip and lower chuck is connected.
Described link is bolt.
The both ends of described upper grip are respectively equipped with latch, offer slot accordingly at the correspondence position of lower chuck.
Described latch and slot are cylindric.
Described latch and upper grip are one-body molded.
Described latch end is dome-shaped.
The device of a kind of charged disconnecting non-loaded cable lead-in wire of the utility model compared with prior art has the following advantages: owing to being provided with clamp assemblies, improve the reliability of anchor leg and extinguishing arc rope; Be provided with latch and slot owing to coordinating, play the guiding role when fit on chuck and lower chuck, be convenient to the cooperation of upper grip and lower chuck; Owing to being provided with link, easy disassembly upper grip and lower chuck.
Accompanying drawing explanation
