A power adapter with nanowire function

Abstract

The invention belongs to the field of power adapters for mobile phones, and relates to adapter nanowire technology, in particular to a power adapter with a nanowire function, including a housing, an adapter body is fixedly installed on the top wall of the inner wall of the housing, and the bottom of the adapter body is connected to There is an input line, the bottom of the adapter body is provided with the first limit roller and the installation frame, the inside of the installation frame is provided with the second limit roller, the inner wall of the housing is fixedly installed with two symmetrical straight plates, and the two A rotating rod is movably connected between the straight plates, and a winding roller is fixedly installed on the outer surface of the rotating rod, and an input plug is provided at one end of the input line outside the casing. In the present invention, the input line is received, and the input line is pulled out during charging. After the charging is completed, the spring reaction force pulls the sliding sleeve to move to the left, and the input line is brought into the casing, and the first limit roller and the second limit roller are added. The wire length between the roller and the winding roller realizes the function of receiving the input wire.

Description

technical field [0001] The invention belongs to the field of mobile phone power adapters, relates to adapter nanowire technology, and in particular relates to a power adapter with a nanowire function. Background technique [0002] The power adapter is a power supply conversion device for small portable electronic equipment and electronic appliances. It is generally composed of housings, transformers, inductors, capacitors, control ICs, PCB boards and other components. Its working principle is converted from AC input to DC output; press the connection The methods can be divided into wall-plug type and desktop type, which are widely used in security cameras, set-top boxes, routers, mobile phones and other equipment.

Problems solved by technology

[0003] The input line of the existing mobile phone power adapter has a certain length intercepted outside the shell, so that the input plug can be easily inserted into the jack of the external power supply, but when the input line is not charging, the part trapped outside the shell is easily damaged. Affect the subsequent use of the input line; at the same time, the power adapter needs heat dissipation when charging. The existing power adapter usually only sets the fan to cool the power adapter at regular intervals, and cannot automatically turn on the fan when the power adapter is charging.
