Description

A grounding wire connection fitting

technical field

The utility model relates to a grounding wire connection fitting.

Background technique

Grounding is a safety measure taken to ensure the normal operation of power equipment or power systems. At present, the commonly used grounding method is to use parallel trench clamps to connect the auxiliary ground wire of the terminal equipment to the main ground wire, and the commonly used parallel trench Generally, the clamp can only be connected one-to-one, that is, it can only clamp one auxiliary grounding wire and one main grounding wire. However, in the process of distribution network construction in recent years, due to the application of distribution automation terminals and new distribution equipment A large number of use or power equipment is added again on the power tower, and this type of terminal equipment needs to be connected to the corresponding main grounding wire through its own secondary grounding wire to ensure effective grounding of the terminal equipment, so it is necessary to use a large number of parallel trench clamps. The auxiliary grounding wire of this terminal equipment is connected to the main grounding wire. At the same time, it is necessary to peel off the outer skin of the main grounding wire several times to connect the parallel clamps. As a result, multiple "pimples" are formed on the main grounding wire, which is not beautiful. It also reduces work efficiency and requires the use of multiple parallel trench clamps, resulting in serious waste; sometimes in order to save the number of parallel trench clamps used, construction workers directly use insulating tape to wrap multiple strands of auxiliary grounding wires and main grounding wires together. However, this connection method leads to the inability to firmly connect the joint, and the adhesive tape is easy to scatter, causing the auxiliary grounding wire to fall off from the main grounding wire. Therefore, it is necessary to design a method that can connect multiple auxiliary grounding wires to the main grounding wire through a parallel trench clamp, and can separately remove each auxiliary grounding wire, and can expand the connectable wires on the fitting again. Quantity of hardware.
