Description

Technical Field

[0001] The invention relates to the technical field of electrical appliance assembly, and in particular to a wire pressing structure of an electrical appliance box. Background Art

[0002] In the prior art, the wire diameters of power cords vary widely, but these power cords must be compressed when in use and must meet the tensile strength requirements. To this end, the current common method in the industry is to fix a row of wire crimping seats on the electrical box, and match the corresponding wire crimping clamps according to the different wire diameters of the power cords. The resulting wide variety of wire crimping clamps is not conducive to material storage management, nor is it conducive to the operation of workshop employees, and is even more detrimental to the universalization of wire crimping clamps.

[0003] Some air conditioner manufacturers try to use as few wire clamps of different specifications as possible for their own convenience. Since the size of the wire clamp does not meet the requirements, when the wire clamp is used to fix the power cord, the gap is either too large, causing the power cord to become loose and not tight, or it is too tight, breaking the skin of the power cord, which poses a serious electrical safety hazard. Summary of the invention

[0004] Based on the above problems, the purpose of the present invention is to provide a wire crimping structure for an electrical box, which has low cost, is easy to operate, and is suitable for crimping wires of various wire diameters.
