Description

Anti-loosening drop-proof plug-and-socket

Technical field

The present invention relates to a kind of plugs and sockets, especially can anti-loosening slip-off preventing be used for the plugs and sockets of power supply and electronic device, electronic equipment.

Background technology

In the various electronic equipments that use at present, plug and socket is by the sheet metal in the metal column of plug or the sheet insertion socket or the connection of hole realization power line or data wire, but this connected mode is not owing to there is fixture, loosening and the problem that comes off often appear in use, though the data wire of electronic equipment is established set bolt in the both sides of plug, because of narrow space is brought unhandy problem, coming off of plug loosening promptly causes the loss of power accident, also has certain danger.

Summary of the invention

For overcoming above-mentioned defective, the object of the present invention is to provide a kind of anti-loosening drop-proof plug-and-socket, this plugs and sockets is provided with bullport plugs and sockets is connected and fixed by grab is set on plug on socket, preferably resolve power supply or data wire and connect loosening and the problem that comes off.

For achieving the above object, described male component comprises a matrix and the plug that is installed on the matrix, wherein, hold row level with both hands from two side direction plugs one of described matrix plug one end far away and be extended with the Elastic Meshing arm that can be received in the described female component, be provided with grab at the front end of described each meshing arm; Be provided with the U-shaped safeguard structure in the nearly plug of described matrix one end both sides, described Elastic Meshing arm passes from described U-shaped safeguard structure; Outer middle side part at described Elastic Meshing arm is provided with the release handle; Described release handle is positioned at U-shaped safeguard structure upside;

Described female component has a pair of bullport and a pair of bayonet socket that is used for receiving with described meshing arm engagement, and this is set at respectively in the described bullport bayonet socket, with respectively with the grab locking mesh of described meshing arm together.

Particularly, described plugs and sockets is a kind of in two plug and socket of power source, three plug and socket of power source, electronic equipment data wire plugs and sockets, USB plug socket and the network wire plug sockets.

Adopt said structure, when male component is inserted in the female component that has in a pair of bullport, the grab of corresponding Elastic Meshing arm front end is directed hole wall, and inwardly compression is mobile, when male component further inserts, the grab of meshing arm front end moves to the bayonet socket from bullport, thereby the bayonet socket in meshing arm grab and the female component is meshed together.Because the Elastic Meshing arm is to hold row level with both hands from two side direction plugs one of described matrix plug one end far away to stretch out, distance is longer, so when making grab break away from bayonet socket, by less power or pressure meshing arm was curved inwardly by elasticity, so that grab can easily break away from engagement with bayonet socket, male component can be drawn out in bullport.Be provided with the U-shaped safeguard structure in the nearly plug of described matrix one end both sides, can improve that the Elastic Meshing arm is opened by accident or drawn bad danger because of accident, can improve safety in utilization widely, and simple in structure, the convenient use.
