Abstract

The invention discloses a power adapter and a power adapter circuit. A shell is included. The shell is formed by an upper shell and a lower shell. A bayonet of the upper shell is clamped to an outer edge side port of the lower shell through a buckle, the upper shell is clamped to the lower shell to form an inner cavity, and a circuit board is arranged in the inner cavity. The circuit board is provided with several electronic components to form a complete circuit of the power adapter, and an input end of the complete circuit of the power adapter is electrically connected to an insertion sheet through a lead. The insertion sheet is fixed to and passes through the upper portion of the lower shell. Energy saving and environmental protection are achieved, a size is small and safety performanceis high. A 5-18W voltage of power accords with a global standard (90-264V), product matching efficiency is high (EU grade VI), a radiation interference accords with an international safety requirement(60% higher than the general performance of a traditional common product), and the adapter and the circuit are made of an imported PC raw material.

Description

technical field [0001] The invention relates to the technical field of power adapters, in particular to a power adapter and a power adapter circuit. Background technique [0002] Power adapter is a power supply conversion device for small portable electronic equipment and electronic appliances. It is generally composed of shells, transformers, inductors, capacitors, control ICs, PCB boards and other components. Its working principle is converted from AC input to DC Output; According to the connection method, it can be divided into wall-plug type and desktop type. It is widely used in security cameras, set-top boxes, routers, light bars, massagers and other equipment. [0003] Because the power adapters currently on the market will heat up too quickly when they are connected to the power supply for a long time, resulting in fire accidents and low safety performance. Contents of the invention [0004] The object of the present invention is to provide a power adapter and a ...
