As the utility model discloses a preferred technical scheme, binding post passes through bolt and nut and cable outdoor termination's binding post fixed connection, and binding post and ground vertical.

As the utility model discloses a preferred technical scheme, extension piece and polygon ground connection link fixed connection, extension piece and binding post swing joint.

As the utility model discloses a preferred technical scheme, the shape of polygon ground connection link is the hexagon, and two limits adjacent each other pass through arc limit fixed connection.

As the utility model discloses an optimized technical scheme, polygon ground connection protection casing mainly comprises the ya keli material, and the inside size of a dimension of polygon ground connection protection casing and the size of a dimension phase-match of polygon ground connection link.

As the utility model discloses a preferred technical scheme, polygon ground connection protection casing rotates with the extension piece through articulated piece to be connected.

Compared with the prior art, the utility model provides a novel 10kV cable outdoor termination ground connection link possesses following beneficial effect:

1. according to the novel 10kV cable outdoor terminal grounding hanging ring, due to the arrangement of the extension pieces, a certain distance is kept between the polygonal grounding hanging ring and a cable terminal in the installation process, so that the grounding wire is hung in enough space and position, and the safety in use is improved;

2. according to the novel 10kV cable outdoor terminal grounding hanging ring, due to the fact that the polygonal grounding hanging ring is arranged and the polygonal design is adopted, the requirement that maintenance personnel hang grounding wires from various angles can be met, the maintenance personnel can be more convenient and fast in the operation process, and the working efficiency is improved;

3. this novel 10kV cable outdoor termination head ground connection link through setting up polygon ground connection link, in daily use, the protection casing covers the ground connection link, prevents to appear because of objects overlap joint such as foreign matter, branch in ground connection link department, causes alternate short circuit. When the circuit needs to be overhauled, the maintainer can open the protection casing with the insulating rod, tests the work of electricity, articulates the ground wire again, has improved maintainer's personal safety.
