Abstract

The utility model provides a three-phase lock type anti-falling safe plug socket which is provided with a mold body and a metal sheet. One end of the metal sheet extends out of the mold body and is connected with the socket, and the other end extends into the mold body and is connected with a lead, and furthermore the metal sheet and the lead are respectively formed in the mold body in one time. The mold body is internally provided with an elastic member. The elastic member is composed of a locking tenon, an elastic connector and a kneading-facilitated projection, and furthermore the locking tenon, the elastic connector and the kneading-facilitated projection are in an integrated structure. The locking tenon and the projection are respectively exposed from the mold body, and furthermore when the projection is kneaded, the locking tenon retreats into the mold body. When the projection is released, the top of the locking tenon springs out of the mold body. The three-phase lock type anti-falling safe plug socket has functions of: preventing looseness between a three-phase plug and a socket because of an external force or non-tight fit; preventing easy loosening and releasing of the plug when a moving tool is utilized; and improving safety and practicability. The three-phase lock type anti-falling safe plug socket has advantages of: simple operation, easy manufacture and easy operation.

Description

Three-phase bayonet type anti-drop safety plug socket

Technical field

The utility model belongs to technical field of electronic devices, is specifically related to a kind of three-phase bayonet type anti-drop safety plug socket.

Background technology

3-phase plug socket uses very extensive in daily life, between existing plug and socket, be all to insert in socket aperture and directly connect by sheet metal, often between the size of some plug and socket because small difference can cause between plug and socket connecting not tight, easily get loose, and often plug can, because of the stressed landing from socket of unexpected situation, affect the useful life of electronic device very much.In some special use occasions, such as the frequent mobile equipment such as electric hand drill, angle grinding machine, electric hammer, just more demonstrate its drawback, because these instruments in use otherwise stop mobile, conversion place and angle, so usually there is the electric tool using power-off due to plug from falling, must go the plug coming off again to plug frequently, sometimes when people aloft or the environment of sealing uses, insertion plug is repeatedly with regard to the serious operating efficiency that affects, there is certain potential safety hazard, be therefore necessary to improve.

Utility model content

The technical problem that the utility model solves: a kind of three-phase bayonet type anti-drop safety plug socket is provided, in die body, be provided with elastomer, elastomer is provided with snap close tenon, on socket, be shaped with square groove, square groove sidepiece is shaped with the lock buckling groove suitable with snap close tenon, in the time that sheet metal on 3-phase plug inserts the three-phase jack that is positioned at square groove bottom, can effectively prevent between 3-phase plug and socket because of external force or coordinate untight former thereby get loose.

The technical solution adopted in the utility model: three-phase bayonet type anti-drop safety plug, there is die body and sheet metal, described sheet metal one end is stretched out die body and is connected with socket, the sheet metal other end stretches in die body and wire connection and sheet metal and wire are all once molded in die body, in described die body, be also provided with elastic component, described elastic component is by snap close tenon, nonrigid connector and be convenient to that projection that hand pinches forms and three is integral type structure, it is outside and while clutching projection in snap close tenon retraction die body that described snap close tenon and projection are all exposed to die body, while decontroling projection, die body is ejected at snap close tenon top.

Further, described snap close tenon outside is arcuation, on described projection, is shaped with anti-slip veins.

Further, described elastic component adopts rubber or sheet metal to make.

A kind of and the matching used socket of three lock bayonet type anti-run safety plugs is also provided, there is socket, on described socket, be shaped with square groove, be located at square groove bottom with the three-phase jack that sheet metal is suitable, on described square groove sidewall, be shaped with the lock buckling groove suitable with snap close tenon.

The utility model advantage compared with prior art:

1, can prevent between 3-phase plug and socket because of external force or coordinate untight former thereby get loose;

2, while thoroughly having avoided using mobile electric instrument, plug easily becomes flexible the phenomenon of deviating from, and makes operator in construction, no longer worry the 3-phase plug inconvenience bringing to work that comes off;

3,3-phase plug is embedded in socket, and hand and other foreign matter all can not misconnection contact live part, have greatly improved fail safe and practicality;

4, use and can avoid child to pull out 3-phase plug causing hand can touch easily the unsafe factor that live part brings by mistake in the family, thereby not only in workplace, be exactly can bring great electricity consumption reliability and fail safe to people in daily life;

5, simple and easy to do, make simply easy operating.

Accompanying drawing explanation

Fig. 1 is the utility model perspective view;

Fig. 2 is and the matching used socket schematic diagram of the utility model.

Embodiment

Below in conjunction with accompanying drawing 1-2, a kind of embodiment of the present utility model is described.

Three-phase bayonet type anti-drop safety plug, there is die body 1 and sheet metal 2, described sheet metal 2 one end are stretched out die body 1 and are connected with socket, sheet metal 2 other ends stretch into and in die body 1, are connected with wire and sheet metal 2 and wire are all once molded in die body 1, in described die body 1, be also provided with elastic component 3, specifically, described elastic component 3 adopts rubber or sheet metal to make.Described elastic component 3 is by snap close tenon 5, nonrigid connector and be convenient to that projection 7 that hand pinches forms and three is integral type structure, and described snap close tenon 5 outsides are arcuation, on described projection 7, are shaped with anti-slip veins 8.When described snap close tenon 5 and projection 7 are all exposed to die body 1 outside and clutch projection 7, in snap close tenon 5 retraction die bodys 1, while decontroling projection 7, die bodys 1 are ejected at snap close tenon 5 tops.The socket using with the utility model is also provided, there is socket 9, on described socket 9, be shaped with square groove 10, be located at square groove 10 bottoms with the three-phase jack 11 that sheet metal 2 is suitable, on described square groove 10 sidewalls, be shaped with the lock buckling groove 4 suitable with snap close tenon 5.

In use, the sheet metal 5 of 3-phase plug inserts in the process of socket three-phase jack 6, and snap close tenon 5 is under the touching of socket wall in retraction die body 1, and after sheet metal 5 and three-phase jack 6 plug together and put in place, snap close tenon 5 automatic springs insert in lock buckling grooves 4; In the time that needs are transferred to 3-phase plug, clutch projection 7 with hand, snap close tenon 5 is retracted again in die body 1, sheet metal 2 departs from the three-phase jack 6 of socket, the utility model can prevent between 3-phase plug and socket because of external force or coordinate untight former thereby get loose, while having avoided using mobile electric instrument, plug easily becomes flexible the phenomenon of deviating from, and makes operator in construction, no longer worry the 3-phase plug inconvenience bringing to work that comes off, and has greatly improved 3-phase plug fail safe and practicality in use.

Above-described embodiment, is preferred embodiment of the present utility model, is not used for limiting the utility model practical range, and the equivalence of being done with content described in the utility model claim therefore all changes, within all should being included in the utility model claim scope.
