Description

Technical Field

[0001] The utility model relates to a foldable power supply pin piece, belonging to the technical field of power supply pin pieces. Background Art

[0002] The AC pin of a traditional power adapter is usually connected to the PCBA using flying wires or spring clips. The traditional AC pin only adds a slot in the contact part between the pin and the shell, and the metal-plastic contact area is limited. After the adapter has been used a certain number of times, especially when there is a difference in the matching degree between the pin and the socket specifications, it is easy for the AC pin to fall out / press into the adapter, causing safety problems. In order to meet the increasingly high requirements of consumers for products, the current power adapter AC pins are developing in a safe, reliable and simple direction; Patent No. CN201921897734.9 discloses a high-strength adapter AC pin, including: a strip plate body with a pin end. The utility model greatly improves the mechanical strength of the AC pin when it is pulled out / inserted from the adapter shell, and meets the consumer's requirements for high safety and reliability of the power adapter.

[0003] The disadvantage of the above-disclosed power pin member is that it cannot be folded better when connected to the adapter, resulting in the power pin member being unable to be stored in the adapter housing and unable to be protected by the adapter housing. For this reason, we design a foldable power pin member. Utility Model Content
