Abstract

The utility model relates to a plug and a socket with an anti-pulling out structure. The utility model is characterized in that a pressure spring is installed in a groove at the upper end of a plug body in the plug, the other end of the pressure spring is supported on one side surface of an inserting piece, and the other side surface of the inserting piece is supported by a pressure block which can extend out of the plug body. A bottom piece is installed on an annular lug boss of a base in the socket; the inner side edge of the bottom piece is made into a straight piece, the outer side edge of the bottom piece is made into a rectangular piece below which a space for inserting the inserting piece of the plug is kept. The utility model has the advantages that the plug is prevented from pulling out from the socket, so that electrical appliances can work stably and effectively for a long time, and the occurrence of an open circuit is avoided.

Description

The plug and socket that has anti-drop structure

The utility model belongs to H01R class technology, particularly relates to a kind of plug and socket that has anti-drop structure.

Because known plug and socket itself do not have anti-drop structure, then 1. in being inserted into the egative film of socket, the inserted sheet in the plug uses the long period, when making both cooperate pine following; 3. when the deadweight of plug bond is big; 3. tighten the state that is inserted in the socket when the wiring of plug plug obscission from socket easily takes place down, therefore exist to guarantee that the electrical appliance long-term stability works the deficiency that can cause electrical appliance to open circuit effectively.

The purpose of this utility model is to overcome the deficiency in the known technology and provides a kind of plug that prevents to come off from socket and guarantee the electrical appliance effectively plug and socket that has anti-drop structure of work steady in a long-term.

The purpose of this utility model is achieved in that

Inserted sheet in the plug of the present utility model can be inserted in the egative film in the socket, described plug construction is, in symmetry two Baltimore grooves of plug body upper end, a stage clip is installed respectively, the other end of its stage clip withstands on a side of two inserted sheets respectively, and the another side of two inserted sheets respectively leans the briquetting that can stretch out the plug body outside.Described socket is, is symmetrically installed with two egative films on the annular boss of base, with the inner side edge in the egative film make straight sheet, its outer side edges is made the right angle knee-piece that the space that can insert inserted sheet in the plug is left in the below.

The front end of the inserted sheet in the above-mentioned plug is made the outside half-cone head of inversion.

Above-mentioned briquetting shape is made the projection that front end is a wedge shape.

The utility model has following accompanying drawing:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the perspective view of briquetting 9 among Fig. 1.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:

By the screw symmetry two egative films 3 that have connection bolt 4 are installed on the annular boss of the base 2 in socket I, the inner side edge of its egative film is shaped as straight sheet, outer side edges is shaped as the right angle knee-piece that the space is left in the below, also is connected with loam cake 5 by attachment screw 6 on base.In addition, one stage clip 8 respectively is installed in two Baltimore grooves of the upper end symmetry of the plug body 11 among the plug II, respectively insert the rear end by the symmetrical trough with straight angle in the plug body and be shaped as the inserted sheet 7 that turns at the right angle, turn a side at its right angle the terminal screw 10 that can connect the two-way incoming line also is housed, moreover the front end that inserted sheet stretches out plug body is made for is inverted outside half-cone head, connect an above-mentioned side that the other end of two stage clips is respectively withstood on two inserted sheets, the another side of two inserted sheets also respectively leans the large end face in the briquetting 9 of projection shape, small end face in its briquetting (front end) is shaped as lozenges and stretches out the plug body outside, and the boss face in the briquetting will be embedded in the plug body.In the space that inserted sheet is inserted in the socket mediella, right angle, the outside knee-piece in the egative film blocks the half-cone head of the front end of inserted sheet.

Advantage and the good effect that the utlity model has are: both prevented that plug from taking off from socket Fall, again when needing from the socket egative film, to pull the plug out of the socket inserted sheet, as long as by the applying light plug In briquetting just can easily plug be taken out from socket. It is long-term to have reached electrical appliance Stablize and effectively work, avoid the generation of breaking phenomena.

Claims

1. plug and socket that has anti-drop structure, socket that plug, base and egative film of being made up of plug body and inserted sheet and loam cake are formed and the inserted sheet in the plug can be inserted in the egative film in the socket form, it is characterized in that: 1. plug construction is, in symmetry two Baltimore grooves of plug body upper end, a stage clip is installed respectively, the other end of its stage clip withstands on a side of two inserted sheets respectively, and the another side of two inserted sheets respectively leans the briquetting that can stretch out the plug body outside; 3. socket is, is symmetrically installed with two egative films on the annular boss of base, the inner side edge in the egative film is made straight sheet, its outer side edges make the right angle knee-piece that the space that can insert inserted sheet in the plug is left in the below.

2. the plug and socket that has anti-drop structure according to claim 1 is characterized in that: the front end of the inserted sheet in the above-mentioned plug is made be inverted outside half-cone head.

3. the plug and socket that has anti-drop structure according to claim 1 is characterized in that: above-mentioned briquetting shape is made the projection that front end is a wedge shape.
