AI Technical Summary

Technical Problem

The operating handle of a molded case switch is difficult to grip and can easily trap and damage insulating gloves, posing inconvenience and safety hazards.

Method used

A plastic-shell switch extension handle is designed, comprising a connecting part, an extension part, and a grip part. The connecting part is sleeved onto the operating handle through a contoured groove, the extension part extends in a direction away from the contoured groove, and the grip part is provided with an arc-shaped grip surface and is pressed against and fitted to the operating handle through first and second abutting members, thereby increasing the grip distance and providing elastic cushioning to accommodate operating handles of different sizes and specifications.

Benefits of technology

It improves the ease of operation of molded case switches, prevents insulated gloves from getting caught in the gaps in the housing, enhances the operating torque, and improves safety and convenience.

Abstract

The utility model relates to the technical field of moulded case switch control, especially relates to a moulded case switch extension handle. It includes connecting portion, extension and holding portion, and connecting portion is provided with the profiling groove, and the profiling groove is sleeved in the operating handle of moulded case switch, and the extension extends from the connecting portion to the direction of departing from the profiling groove, and the holding portion is arranged at one end of the extension far from the connecting portion, and the holding portion is provided with the arc holding surface. The user can first sleeve the moulded case switch extension handle on the operating handle of moulded case switch, and then changes the on-off state of moulded case switch by the force of holding portion. Because the extension increases the distance between holding portion and the shell, the user will not clamp the insulating gloves into the shell gap when operating, and the force from the holding portion has a large torque, and the arc holding surface is also convenient for the user to exert force, improving the convenience of moulded case switch control.
