Specific implementation mode

It, below will be to the technology of the utility model to keep the purpose of this utility model, technical solution and advantage clearer Scheme is described in detail.Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are not before making creative work Obtained all other embodiment is put, the range that the utility model is protected is belonged to.

Embodiment 1：

In the present embodiment, a kind of Anti-disconnecting socket, as shown in Figure 1, Figure 2 and shown in Figure 10, including upper cover 1, pedestal 2, conductive sheet 3, A Card 4, B cards 5, drive member 6 and spring 7, upper cover 1 and pedestal 2 snap together to form socket shell, as shown in figure 5, the bottom Seat 2 on be provided with firewire slot 21, zero curve slot 22 and ground wire casing 23, as shown in Figure 3 and Figure 4, in above-mentioned upper cover 1 with firewire slot 21, Zero curve slot 22 and 23 corresponding position of ground wire casing be respectively arranged with through-hole with above-mentioned firewire slot 21, zero curve slot 22 and ground wire casing 23 separately constitute firewire jack 8, zero line jack 9 and ground wire jack 10, in firewire jack 8, zero line jack 9 and ground wire jack 10 It is both provided with conductive sheet 3, at this point, the utility model combines to form structure identical with three corner socket in the prior art.With it is existing Having unlike technology, the cell wall height of above-mentioned ground wire casing 23 is less than the height of firewire slot 21 and zero curve slot 22, so that upper After lid 1 is snapped together with pedestal 2, installation space is formed between ground wire casing 23 and upper cover 1.

As shown in Fig. 6, Fig. 7 and Fig. 8, above-mentioned drive member 6 includes that A columns 61, B columns 62 and the C to link together is stood Column 63, and the drive member 6 is mounted on by the way that above-mentioned spring 7 is up and down in above-mentioned socket shell, and C columns 63 are worn Go out the socket shell, user can drive above-mentioned drive member 6 up and down in socket shell by C columns 63, namely drive It moves above-mentioned A columns 61 and B columns 62 moves up and down in socket shell, moreover, as shown in Figure 10, above-mentioned A columns 61 and B columns 62 The both sides of ground wire casing 23 are respectively placed in, the top surface of the A columns 61 and B columns 62 is disposed as towards the inclined slope of ground wire groove center Above-mentioned A cards 4 are overlapped in the slope surface of above-mentioned A columns 61 by face, and above-mentioned B cards 5 are overlapped in the slope surface of B columns 62, this When, above-mentioned A cards 4 and B cards 5 can move up and down in above-mentioned installation space and with above-mentioned A columns 61 and B columns 62, such as scheme Shown in 10, A cards 61 and B cards 62 form herringbone structure, and are formed and can be inserted into simultaneously between A cards 61 and B cards 62 The gap of earth pin is blocked, and limits the one end of above-mentioned A cards 61 and B cards 62 far from described ground wire casing 23 and withstands on institute It states and forms limit in upper cover 1.

When the utility model is under normal condition, due to the A columns 61 for withstanding above-mentioned A cards 4 and B cards 5 Be mounted in socket shell by spring 7 with B columns 62, when being inserted into earth pin, due to A cards 61 and B cards 62 by To active force directed downwardly, therefore A cards 4 and B cards 5 will unclamp under the indirectly-acting of spring, so as to user can easily by Earth pin is inserted into.And when user needs to pull out earth pin upward, earth pin is applied to A cards 4 and B cards 5 On active force upward, however since A columns 61 and B columns 62 are respectively against A cards 4 and B cards 5, and A cards 4 and B cards One end of the remotely wire casing of piece 5 is against in upper cover 1, therefore, if at this point, user drives 61 He of A columns not over C columns 63 B columns 62 move certain displacement, are no longer bear against A cards 4 and B cards 5, and unclamp A cards 4 and B cards 5, then A cards 4 and B Card 5 will block earth pin so that user cannot extract earth pin, if driving A vertical using by C columns 63 Column 61 and B columns 62 move and unclamp A cards 4 and B cards 5, and user just can extract earth pin.Above-mentioned spring 7 is set It sets, the A columns 61 moved and B columns 62 (drive member 6) can be made to reset and withstand A cards 4 and B cards 5 again, And it can give drive member 6 to provide an active force upward, to drive A columns 61 and B columns 62 to hold out against A cards 4 and B cards Piece 5.

Using the above structure, the utility model can prevent earth pin and plug from being taken off easily from the utility model It falls, security performance is high, and assembling is simple and convenient, highly practical.

Preferably, limit above-mentioned A cards 4 close to the face of B cards 5 and B cards 5 close to the face of A cards 4 as plane, In this way, when forming the structure of herringbone between the two, gap width between the two is actually the edge of two planes Between gap can provide the clamping force of bigger when it blocks earth pin.

Embodiment 2：

The present embodiment is further improved on the basis of embodiment 1, in the present embodiment, such as Fig. 6, Fig. 7, Fig. 8 and figure Shown in 10, connecting plate 64 is additionally provided between above-mentioned A columns 61 and B columns 62, the upper end of the connecting plate 64 be provided with it is above-mentioned 10 compatible square groove 66 of ground wire jack, after the utility model installs, above-mentioned square groove 66 is being located at above-mentioned ground wire casing 23 just Top, in this way so that the more specification of ground wire jack 10 is conducive to user and inserts earth pin.

Further, in the present embodiment, as shown in Figure 10, when the utility model be in normal condition (namely A columns 61 push up Firmly A cards 4, when B columns 62 withstand B cards 5), on the one end of above-mentioned A cards 4 and B cards 5 far from above-mentioned ground wire casing 23 Surface is contacted with the lower surface of above-mentioned square groove 66, at this point, above-mentioned square groove 66 will limit A cards 4 and B cards 5 so that A cards 4 and B cards 5 cannot be moved upwardly by, so that the position of A cards 4 and B cards 5 in the present invention is more fixed, When being inserted with earth pin, the coupling mechanism force bigger that the A cards 4 and B cards 5 can provide, locking effect is more preferable.

Embodiment 3：

The present embodiment is further improved on the basis of embodiment 2, in the present embodiment, such as Fig. 7, Figure 10 and Figure 11 institute Show, raised line 65 is provided on above-mentioned connecting plate 64, which is arranged on the cell wall of above-mentioned square groove 66, and is installing Afterwards, between the just grafting of raised line 65 and above-mentioned A cards 4 and B cards 5, the width for limiting the raised line 65 is less than A cards 4 and B cards Gap width between piece 5 is stayed with the movement for A cards 4 and B cards 5 and sets surplus, and limits the raised line 65 and protrude connecting plate 64 height is less than the width (namely length less than above-mentioned gap) of above-mentioned A cards 4 and B cards 5, to avoid the raised line 65 Ground wire jack 10 is formed and is blocked.

With this configuration, when above-mentioned A cards 4 and B cards 5 glide along slope surface, which can block A cards Piece 5 and B cards 6, fall to avoid A cards 5 and B cards 6 from ground wire jack 10, and then enhance the stabilization of the utility model Property.
