Further, described contact is watchband type contact, facilitates its connection with cable conductor.
Further, the step that can be located by connecting with cable conductor end of formation on the internal chamber wall of the contact, contact with
Cable conductor is fixedly connected, and the outer face of contact slightly protrudes from the outer face of cable conductor.
Further, described cut-off is connected as a single entity in a ring and with metallic shield, when contact and metallic shield connect
After connecing, described cut-off is sandwiched between two contacts.
Further, described cut-off keeps two sections of cable conductor depth one positioned at the center of the metallic shield
Cause, size symmetrical.
The present invention also provides a kind of cable testing apparatus, comprising above-mentioned experiment high-tension cable plug-in transition joint, bottom
Seat and two metal platforms being placed on base, the metal platform can be moved horizontally relative to base, described metal platform
It is provided with the fastener for fixing cable；Described experiment is located at two metal platforms with the transition joint of high-tension cable plug-in
Between.Rejected region, observation adjustment defect situation are opened by mobile metal platform.Plug-in transition joint is integrally placed to bottom
On seat, both sides cable is separately fixed on two independent horizontally movable metal platforms, by mobile metal platform, can be right
Respective cable conductor carries out plug operation, realizes rejected region folding, and observation adjustment is carried out to defect, is easy to experiment to carry out.
Further, described base is movable base, is conveniently moved integrally.
Compared with prior art, high-voltage cable middle joint of the invention uses revocable plug type structure, watchband
Formula contact can realize that conductor is closely connected with metallic shield, it is ensured that high current through-current capability；Plug-in transition joint entirety
It is placed on movable base, rejected region can be opened by mobile metal platform, observation adjustment defect situation is easy to experiment opening
Exhibition.
