Problems solved by technology
However, this installation method often leads to another problem, that is, the tightening degree of the screws is not easy to grasp, and the operator needs to have certain operating experience.
Insufficient tightening of the screw may easily lead to loosening of the wire, and excessive tightening of the screw may cause the wire to be squeezed and deformed, reducing the effective conductive cross-sectional area of the wire, and prone to excessive local current. In severe cases, it may cause circuit failure or even failure electrical hazard
Therefore, electrical connection operators need to always grasp the appropriate screw compression force to ensure the stable connection of the wires without damaging the cross-sectional area of the wires. This puts higher requirements on the field operators and will affect the efficiency of field operations

Description
technical field [0001] The invention belongs to the technical field of switch cabinets, in particular to a wire connecting hardware. Background technique [0002] A large number of electrical connection operations are required in the switch cabinet, so naturally there are a large number of wire connection fittings preset in the switch cabinet. The wire connection fittings connect and fix the wires on the switchgear of the switch cabinet. Currently, the wire connection fittings are widely used. Usually, a screw and a clip are used to clamp and fix the wire. As long as the screw is tightened correctly, this installation method can ensure the stable connection of the wire. However, this installation method often leads to another problem, that is, the degree of tightening of the screws is not easy to grasp, and the operator needs to have certain operating experience. Insufficient tightening of the screw may easily lead to loosening of the wire, and excessive tightening of the s...
