Power adapter improved structure 【0001】

This creation is about a power plug, especially a power adapter improved structure.

【0002】

In general, a power adapter is a power supply conversion device for small portable electronic devices and electronic appliances. It is generally composed of a casing, a power transformer, and a rectifier circuit, and can be classified into an AC output type and a DC output type according to the output type thereof; According to the connection method, it can be divided into wall-mounted and desktop. Widely used in telephone handsets, game consoles, walkmans, notebook computers, cellular phones and other devices.

[0003]

In the case of a wall plug, the power adapter has a plurality of pins. When the power adapter is combined with a socket, a plurality of pins are combined with a plurality of sockets of the socket. Generally, the grounding pin of the safety socket is used. Regardless of the national sockets, the grounding pins should theoretically be connected to earth potentials, for example, by connecting the electrical equipment to the outer casing through the grounding pins and grounding, so as not to leak or damage the electrical appliances, while other pins are It can be a live wire pin or a neutral pin for supplying power.

[0004]

Furthermore, although countries have their own specifications for sockets, there is still a difference in slot spacing between the international sockets, that is, the distance between the ground pins and the two power pins is not uniform, so if the ground pins are If the distance between the other two power pins is too large or too small, the standard plug will not be able to fit into the socket. For example, if the pin is forced to form a transitional fit with the slot, the pin will be deformed, and it takes a lot of effort to remove the pin or even tighten. The plug of the power adapter is damaged in the slot, and if the pin is loosely engaged with the slot, there is also a concern that the power supply is short-circuited. Therefore, how to provide a power adapter and improve the pin-and-socket relationship of the power adapter to improve the safety and convenience of use has become an important topic for researchers involved in the industry.
