The terminal consists of an insulated base, an insulating barrier, line element, insulating base body, a connection to the insulator base and is arranged on the insulating clapboard, a wiring including wire clamp, screw, nut and a supporting frame, the supporting frame is in the shape of U, wire clamp placed in the support frame, the nut and screw along the support frame U - on the long hole wire two end of the clip, clip on wire by wire clamp and conductive plates, on the surface of two sides of multi row wire clamp lug, with one to two convex ribs on the convex block, which is characterized in that the conductive sheet surface protrusions on both sides of multi row bump, bump and the upper surface the central component arc, with one to two convex ribs on the circular arc surface, convex block and a convex block is formed on the surface of zigzag, conductive sheet middle is a convex platform, the central platform is provided with a threaded hole and the insulation base by bolts attached to the surface of a conductive sheet under the projections at both ends A positioning block shaped supporting frame is connected with the U block, two wire clamp are respectively arranged on the both sides of the platform and the conductive plates are clamped together with the conductive sheet on the wire clamp and the conductive strip bump (staggered occlusal wire clamp.

The terminal wire spring relay connector is connected, each region consists of an insulating seat, U type rack, nut, inner six angle screws and the upper and the lower movable block, the upper and the lower movable block between the relative contact surface is provided with a connection hole, inner six angle screw in the movable block through the nut, its purpose is to for the cable of different thickness directly connected with current terminals. Compared with the existing technology, it can flexibly combine the number of splicing terminal units, and can be pressed to connect single or multiple cable lines. The connection is strong and reliable, and the installation and maintenance are simple and convenient.
