The opening at one end of the L-shaped locking slot moves downward and rotates to the other end of the corresponding L-shaped locking slot. Under the compression of the spring, the two locking posts can be respectively locked in the corresponding L-shaped locking positions. In the groove, in order to realize the clamping connection between the connecting rod and the insulating operating rod.

The connecting plate is fixedly connected to the connecting rod by rivets, and the connecting plate is formed by die-casting of high-quality aluminum alloy.

The grounding wire is made of twisted strands of high-quality annealed copper wires, and the grounding wire is wrapped with a soft and high-temperature-resistant transparent insulating sheath.

The insulating operating rod is made of epoxy resin color tube.

The beneficial effects of the utility model are: the utility model is suitable for the electrical cabinet of the grounding trolley in the substation, and is often used for sealing the ground of the busbar and when the ground is sealed by the main switch for maintenance. The use of the plum blossom contact grounding device can make the connection with the electrical equipment tight and reliable, and will not fall off at will and cause accidents. It can be installed and disassembled by plugging force, and the operation process is simple, fast and convenient.
