Description

Technical Field

[0001] The utility model relates to the technical field of sockets, in particular to an anti-electric shock protection device. Background Art

[0002] Modern homes are inseparable from sockets. Sockets are a common electrical facility used to connect household appliances to the power grid, providing a lot of convenience for our lives. Sockets are mostly divided into two-pin or three-pin sockets, which are then compatible with two-pin flat plugs and triangular plugs. At present, most electrical appliances are plugged into sockets for direct insertion. This method relies entirely on the contact of metal sheets, which not only makes the socket easy to loosen when plugging and unplugging the plug, but also due to improper operation, the fingers can easily touch the metal sheet of the plug unconsciously, causing the risk of electric shock. In order to avoid this situation, a baffle with a rebound function is usually provided at the plug interface to avoid direct contact with the metal sheet. However, due to children's curiosity or young age, this type of socket, when it is inserted into a single hole, its baffle will still be opened, and then plugged into the plug interface, such as when plugged into the live wire plug interface, it will cause the risk of electric shock, thereby failing to protect their personal safety well. For this reason, we have proposed an anti-electric shock protection device. Utility Model Content

[0005] Optionally, two-pin flat plug baffles are fixed on both sides of the linkage frame, the tops of the two-pin flat plug baffles are inclined, and a through hole that can be penetrated and plugged is opened on the linkage frame.

[0006] Optionally, a connecting plate is movably connected inside the linkage frame, and the top of the connecting plate is inclined, and the inclined surface thereof corresponds to the through hole.

[0011] The utility model has the following beneficial effects:

[0012] 1. The anti-electric shock protection device can close the power supply interface by its triangular plug baffle, two-pin flat plug baffle and connecting plate when not in use, so as to prevent foreign objects from falling into the plug interface and causing a power short circuit. In addition, under the action of the first spring force, the triangular plug baffle, two-pin flat plug baffle and connecting plate can close the plug interface in time when the socket is unplugged, thereby preventing electric shock and thus playing a protective role.

[0013] 2. The anti-electric shock protection device can prevent the push column in the socket from moving by enabling the corresponding positioning plate to still abut against the triangular plug baffle or the linkage frame when the push column in the socket is not pushed at the same time, thereby effectively preventing a single object from being inserted into the socket, so that the plug can be opened and prevented from being connected to the live wire, thereby achieving an anti-electric shock protection effect.
