Description

British standard power adapter with brushed pattern

technical field

The utility model relates to the technical field of power adapters, in particular to a British-standard power adapter with wire drawing pattern.

Background technique

With the improvement of consumption level, consumers not only pay attention to the quality of electronic products, but also pay more and more attention to the decorative effect of the surface of the shell. The shell with texture is very popular among consumers because of its novel and beautiful appearance. The plug of the British power adapter is a three-pin plug, and one of the longer pins is used for unlocking, so that the other two metal pins can smoothly contact the power contacts in the socket. However, the unlocking pins of the existing British plugs also take into account the function of grounding. Therefore, most of the unlocking pins also use metal parts. Currently, some metal pins on the market are only used for unlocking and do not need to be used for grounding. , The use of metal parts will increase the cost, and the contact between the pins and the internal copper pins is not firm, easy to loosen, and the temperature rise is easy to exceed the safe range, causing the plastic shell to melt, causing safety hazards.
