Description

Plug and socket adapter

Technical field

The invention relates to a power plug and socket adapter. Say

Background technique

The international electrical standards are inconsistent, and most countries and regions do not have uniform standards for electrical plugs and power outlets. This allows a country or region to use electrical appliances in another country or region because plugs and sockets cannot be matched. Not available. With the development of international trade and culture, many household or portable electrical products are becoming more and more popular in different parts of the world. With a power plug and socket adapter that is convenient to carry, safe, and applicable. It can solve the matching problem of plugs and sockets of different standards.

There are some power plugs with adaptable functions on the market. Some of them have a variety of standard plugs, which can be plugged into different standard power sockets. They are also designed with sockets. They are suitable for plugging electrical plugs. Switching between different standard plugs and sockets makes the user's electrical plugs adaptable to different sockets. There are many types of multi-function power plugs with such a function, but the structural functions are not perfect, and some are made of single The plug and socket form a kit, which is temporarily combined during use, which is inconvenient to operate and carry, and some integrate the functional parts together, but the safety is low, the operation is complicated, or the load is small, and it is not suitable for large electrical appliances.
