Description

Combined safety plug with fuse

technical field

The utility model relates to a combined safety plug with a fuse, in particular to a plug structure which can contain the fuse inside the plug.

Background technique

The power source of general daily life and industrial equipment is mainly connected by wire plug and socket, and conducts current for use. The convenience of using electricity also brings concerns about the safety of using electricity. Because the power load is too high, it is easy to cause the wire to catch fire or even cause a fire. Therefore, many countries have various safety regulations and specifications referred to as "safety regulations" on how to respond to the power load. ", not only for domestic manufacturers, but also for plugs used in imported electrical appliances, or simple plug products and their components (parts). For example, some British plugs have a fuse design inside, and usually this kind of fuse is a tubular body for easy replacement or installation.

In addition, although many plugs have fuses that meet safety standards, their assembly and lack of an integrated design with the live wire terminal and the live wire in the wire are not conducive to quick assembly.

The core wires on each terminal may fall off (the reason for the fall may be due to long-term oxidation, pulling away from the fixed point or due to artificial construction and assembly, or loosening after long-term use), resulting in the lack of isolation between the core wires of the wire. If it is touched, it will cause a short circuit and cause danger, so there is still room for improvement in its safety.
