Embodiment

Below in conjunction with drawings and Examples invention is described in detail.

Fig. 1 is the generalized section of one embodiment of the invention.As shown in Figure 1, the safety socket that the present invention proposes comprises female receptacle 2 and the base 5 that embeds setting up and down, be symmetrically installed with a pair of transversely movable electrode contact blade 1 in the left and right sides of female receptacle reverse side, on this two electrode contact blade hold down gag is installed all, it comprises the spring 3 that is enclosed within on the electrode contact blade transverse arm and the compressing tablet 4 of spring outer end; Simultaneously a self-lock switch 8 is installed also in base, this self-lock switch is fixed between female receptacle and the base, and its top holds up female receptacle, and its both sides susceptor surface is all upwards stretched out an oblique top post 7 respectively, and a stop column 6 is stretched out in the oblique top post outside.

Fig. 2 is for originally showing the generalized section of female receptacle among the embodiment.As shown in Figure 2, female receptacle 2 tops are dull and stereotyped, have a pair of jack 24 that cooperates with plug base pin on it, this stretches out a pair of cantilever 26 downwards to the socket inboard, this plays position-limiting action to cantilever to pin, electrode contact blade can only outwards be moved, and this is to stretching out sidewall 25 under the socket lateral, and the bottom margin of two side outwards vertically is bent to form outer flanging 21; The left and right sides of female receptacle reverse side is stretched out the extension arm 22 of two groups of symmetries respectively downwards, hangs on the arm and is equipped with installing hole 23; As can be seen from Figure 1, electrode contact blade 1 is horizontally installed in this installing hole.

Fig. 3 is the generalized section after the assembling of electrode contact blade and hold down gag in the present embodiment.As shown in Figure 3, electrode contact blade 1 is a H shape conducting structure, and the inner of its transverse arm 11 is provided with step 12, the outer end is with compressing tablet 4, the centre also is with spring 3, and the two ends of spring are kept out by step 12 and compressing tablet 4 respectively, but this compressing tablet move left and right on transverse arm makes spring compression and loosens; On the perpendicular arm top near step one end, its outward flange is provided with is convenient to the guiding surface that pin inserts simultaneously.

Fig. 4 is the generalized section after the assembling of base and switch sections in the present embodiment.As shown in Figure 4, base 5 is an open-topped box like structure, and its top inwardly vertically is bent to form the interior flanging 51 that cooperates overlap joint with outer flanging 21; Protrudes upward a self-lock switch 8 in the middle of its bottom surface, this self-lock switch comprises the bearing 81 that is fixed on the base and a shift bar 82 that protrudes upward from bearing, and this shift bar telescopically is fixed in the bearing, and its top and female receptacle are fixed and with its picking-up.

In conjunction with Fig. 1 and shown in Figure 4, in base 5, self-lock switch 8 both sides arrange an oblique top post 7 and stop column 6 respectively, and the top of oblique top post is stretched into and hung between arm 22 and the compressing tablet 4, be disposed on the stop column 6 in the oblique top post outside, this stop column is used for restriction extension arm 22 and moves downward.

As Fig. 5, Fig. 6 and shown in Figure 7, compressing tablet 4 is made of with middle back-up ring is integrated the cylindrical handle of the left and right sides, and on the transverse arm of electrode contact blade, the cylindrical handle of compressing tablet both sides contacts cooperation with oblique top post 7 to compressing tablet by shield ring sleeve.See from Fig. 6, Fig. 7 to draw that in the present embodiment, socket each side has a pair of oblique top post 7 and stop column 6.

That sees from Fig. 1 goes out, and in integrally-built connection, female receptacle 2 adopts embedded the connection with base 5, and the outer flanging of female receptacle bottom margin is blocked in the interior flanging below of bottom top, struts by self-lock switch 8 between female receptacle and the base simultaneously.

When not inserting plug, the stop column 6 on the base 5 withstands the perpendicular arm of electrode contact blade 1 because electrode contact blade is installed on the female receptacle 2, so the time female receptacle by not going down; When inserting plug, the pin of plug laterally promotes a section to electrode contact blade by the guiding surface on the perpendicular arm of electrode contact blade and moves, thereby causes the position of stop column and electrode contact blade to stagger, and this moment, female receptacle can press down.

When plugging in but when not pressing female receptacle 2, the lateral displacement extrusion spring 3 of electrode contact blade 1, the elastic force of its generation is very little, thereby makes the plug of plug very light; When female receptacle is pressed downwards, its compressing tablet 4 that drives spring one side moves downward together, the ramp effect of two of compressing tablet 4 cylindrical handles and oblique top post 7 in the process that moves downward and produce lateral displacement and compress compressing tablet 4, the power that is caused electrode contact blade to withstand pin thereby the elastic force of spring strengthens strengthens, thereby makes plug be difficult to extract.

The present invention has carried out the integration design with socket and its switch, controls pressing and ejecting of female receptacle by switching device, and the connecting and disconnecting of control electrode contact, and it is simple in structure, and is easy to operate, has significantly improved the fail safe of socket.

Above-described embodiment only is used for explanation the specific embodiment of the present invention.Should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and variation, these distortion and variation all should belong to protection scope of the present invention.
