Description

Multifunctional AC and DC power socket

The invention relates to a socket, in particular to a multi-functional integrated AC and DC power socket which simultaneously provides AC power and DC power, and belongs to the field of socket production.

Background technique

With the development of modern society, various electronic digital products (such as mobile phones, MP3, MP4, digital cameras, video cameras, etc.) have entered our lives. At present, many electronic digital products are charged by direct current (DC) power supply. For safety considerations, This is an inevitable choice and trend. At present, there are two main ways to charge these electronic digital products: one is to use the charger to connect to the AC power supply for charging. Therefore, in order to avoid running out of power and affecting normal work, study and life, people will carry chargers with them, or put a charger at home and office, and there will be a lot of chargers for various electronic and digital products. , very troublesome, not only brings pressure on physical strength and spirit, but also forms a waste, and does not conform to the concept of environmental protection; another charging method is to charge directly through a data transmission interface with a DC power supply, such as a USB interface. Electronic and digital products can be charged through the USB interface, such as mobile phones, MP3, MP4, digital cameras, video cameras, etc., and this will be a major trend, and will gradually form a unified DC power supply standard in the industry. The defect of the method is: only charge through the USB interface of the computer, but the computer is not available anytime and anywhere. When we are on a business trip, when we are resting in a hotel or when we are not using the computer, it will also be damaged because there is no USB interface. Unable to charge.

Further, the DC power jack is a USB jack, the power input end of the USB jack is correspondingly connected to the DC power output end of the AC-DC power conversion module, and the data line end of the USB jack is suspended . This is because from the perspective of current electronic digital products, the DC power lines or data lines all use USB ports, which is currently the most standard connection port for computer peripherals, widely used and easy to use. The USB jack can be arranged at any position on the casing as required, as long as the conditions of convenient use and aesthetics are met. The number of USB jacks can be determined according to the actual usage environment.

Furthermore, a DC power supply charging status indicator light is also provided on the housing, and a DC power supply charging detection circuit is also provided in the housing, and the power input terminal of the DC power supply charging status indicator light is connected to the DC power supply. The power output end of the power charging detection circuit is connected, and the power input end of the DC power charging detection circuit is correspondingly connected with the DC power output end of the AC/DC power conversion module. The DC power supply charging detection circuit judges whether the electronic digital product is fully charged according to the current status of the charging circuit, and displays a red light when charging and a green light when fully charged to let users know the charging status at a glance.

The beneficial effects of the present invention are:

The present invention can directly charge more and more electronic digital products without special chargers. Under the condition that sockets in various places are replaced by the present invention, people can charge electronic digital products almost anytime and anywhere. It greatly facilitates people's charging needs, saves money and worry, and is also conducive to environmental protection. From the perspective of ease of use, it promotes the rapid development of the modern "electronic society".
