AI Technical Summary
The cable plugs of existing small electrical equipment have poor structural strength, which makes them prone to cracking during long-term use, and increasing the amount of material used will increase production costs.
The design incorporates a limiting mounting part and a cable protection sleeve inside the housing. By embedding the limiting protrusion into the limiting mounting part, the amount of housing material used is reduced while increasing structural strength. The friction between the cable protection sleeve and the housing is used to disperse the tensile force and prevent the cable from directly rubbing against the housing.
This improved the tensile strength of the shell, reduced production costs, and maintained the stability and strength of the structure.
