Description

Technical Field

[0001] The utility model relates to the technical field of power plugs, in particular to an anti-falling device for a power plug. Background Art

[0002] The connectors of electronic products and the plugs of electrical appliances are called plugs. Household AC power plugs and sockets have male connectors with rod-shaped or copper-plate protrusions, which are physically inserted into female connector-type power sockets with slots or recesses. The size is an important technical requirement related to whether plugs, sockets and converters can be used safely and whether they meet the general interchangeability requirements to avoid misinsertion. Unqualified size will affect user use or cause hidden dangers such as poor contact and misinsertion, which may damage the equipment at the least and cause fire and electric shock accidents at the worst.

[0003] During the installation and use of power plug equipment, the plug often becomes loose and falls off. If the equipment is powered by a single power source, the loose and falling plug may cause direct power failure or short circuit of the equipment, and even pose a fire hazard. If the equipment is powered by dual power sources, the falling off of a single power source is difficult to detect. When one power plug of the equipment falls off and the other power source fails, the equipment may be abnormally powered off and shut down, thereby causing equipment failure or configuration loss. Therefore, it is very important to prevent the power plug from falling off. Therefore, the utility model proposes an anti-falling device for a power plug to solve the problems existing in the prior art. Utility Model Content
