Description

Technical Field

[0001] The utility model belongs to the field of AC sockets, and particularly relates to a waterproof structure of an AC socket. Background Art

[0002] An AC socket refers to a socket that can only pass through an alternating voltage. Different from a household wall socket, it can only be used for certain electrical products, such as a UPS power supply, a charger, a set-top box, an office display device, a fitness equipment, etc. Usually, what is referred to in the market is an appliance socket, which conforms to the IEC60320 electrical standard.

[0003] Some waterproof structures for AC sockets have been specifically developed in the prior art. For example, the Chinese patent with the publication number of "CN115995716A" discloses "a waterproof AC socket". The AC socket adopts an oval design for its outer shape and adds a sealing ring. Compared with the conventional square design, the sealing performance of the product is greatly increased, effectively preventing rainwater from entering the product cavity through the gaps on the outer side of the housing. When the power plug is inserted into the socket, a rubber ring is added at the root of the PIN pin of the AC socket, and interference is generated between the jack and the rubber ring at the root of the PIN pin, effectively preventing the splashing of rainwater and preventing short circuits caused by rainwater.

[0004] Although the sealing ring added by adopting an oval shape for the outer shape of the AC socket can effectively prevent water from entering, and the interference between the jack and the rubber ring at the root of the PIN pin effectively prevents the splashing of rainwater and prevents short circuits caused by rainwater, when the user uses the above product, when the AC socket is separated from the plug, the AC socket cannot effectively play a self-protection effect, which will increase the probability of water entering the AC socket and causing it to malfunction. Moreover, when the AC socket is exposed for a long time, the internal parts of the AC socket will rust, which will pose a safety hazard when the AC socket is continued to be used and is not conducive to improving the service life of the AC socket. Summary of the Utility Model

[0005] Aiming at the problems mentioned in the background art, the purpose of the utility model is to provide a waterproof structure of an AC socket to solve the problem that the AC socket cannot be independently protected.
