Description

An anti-falling plug and an anti-falling charger

technical field

The embodiments of the present invention relate to the technical field of chargers, in particular to an anti-falling plug and an anti-falling charger.

Background technique

At present, the charger plugs, electrical plugs, and USB (Universal Serial Bus, Universal Serial Bus) plugs on the market cannot be completely fixed on the socket, as shown in Figure 1, including a housing 11 and two pins 12 for charging. When in use, directly insert the prongs of the plug into the socket on the wall. However, due to the uneven quality of sockets on the market, the bite between the plug and the socket is not tight, resulting in loosening between the plug and the socket, causing the interruption of the charging process. Sometimes multiple times of plugging and unplugging are used too many times, and it is easy to cause looseness between the plug and the socket, causing the plug to fall off. At this time, the user can only hold the plug with his hands, so that the plug is fixed on the socket and forms a good contact, so that the charging can be successfully completed. Therefore, it is easy to loosen between the plug and the socket in the prior art, which directly affects the user's charging use.
