Inner wire chuck and chuck pressure cap are matched for clamping tightly the structure of inner wire while realizing clamping inner wire, also coordinate the structure in space between inner wire chuck rear end wedging cable insulation and inner wire to achieve and inner wire is sealed in the effect in inner wire chuck, and then coordinate contact pin to be threadedly secured on chuck pressure cap, between contact pin rear end face and the front end face of cable insulation the structure having a sealing ring to seal, achieve the sealing of inner conductors, i.e. achieve being tightly connected of contact pin and cable.
The spike knocked in after suit inner wire chuck it is additionally provided with in space between the copper cash of described inner wire, after suit inner wire chuck, spike being knocked in the space between inner wire copper cash so that inner wire expands, the taper shell fragment deformation of inner wire chuck front end is strengthened fixing.
To sum up, the invention has the beneficial effects as follows:
1, the present invention is applicable to the electrical connection of high-pressure coaxial cable and high voltage device, it is possible to ensure good electrical contact, has accomplished the excellent sealing to transformer oil while realizing quick grafting,
2, without welding between contact pin with cable, assemble welding step is eliminated, simple for structure, easy for installation, saving of work and time, reduce product cost.
