Embodiment

Below in conjunction with drawings and Examples, the utility model is further illustrated.

As shown in Fig. 2 to 3 figure, be the utility model the first embodiment, it comprises a mother socket 10 and a public plug 20, described mother socket 10 is provided with terminal base 11, at coated insulation framework 19 and the plastics housing 12 of terminal base 11 outer rims.The top (or bottom) of described two housings is provided with a through hole running through, and establishes for 13 groups, a button.Described button 13 bottoms are connected with a U-shaped lamellar body 14, and two ends of described U-shaped lamellar body 14 are respectively equipped with hook part 15, and two middle sections, outside of U-shaped lamellar body 14 respectively project a fixed axis 16.On two fixed axis 16, be respectively arranged with limit spring 18, the hook part 15 of U-shaped lamellar body 14 ends can be butted on terminal base 11, and with its keeping parallelism, to form a complete fastening structure person.

The structure of public plug 20 is identical with existing structure, is mainly provided with terminal base 21, in the coated insulation framework 22 of terminal base 21 outer rims.In the insulation framework 22 of described terminal base 21 tops, offer two fixing holes 23, to form corresponding fastening structure, and terminal base 21 and insulation framework 22 is latter half of coated with plastics housing 24.

As Fig. 3, in conjunction with time, the insulation framework 22 directly public plug 20 being exposed is inserted the opening of the plastics housing 12 of mother socket 10, now, described insulation framework 22 front ends are along the gradient of U-shaped lamellar body 14 hook parts 15, and make hook part 15 be insulated framework 22 jack-up by the elastic force of limit spring 18, and the walking thereon along the push-on force of insulation framework 22, until described insulation framework 22 is shifted bottom onto, and the hook part 15 of U-shaped lamellar body 14 hooks in the fixing hole 23 that is stuck in insulation framework 22, the fastening structure of the two is fastened mutually, and make the two terminal base 11, 21 are in contact with one another, complete the assembling of USB connector.

By like this; make the USB connector of having assembled as touched because of carelessness, pull time; because the fastening structure of the two fastens (be the hook part 15 of U-shaped lamellar body 14 front ends in mother socket 10 hook be stuck in the fixing hole 23 that public plug 20 insulate in framework 22) mutually; therefore can be because not pullling the line body of USB connector 1 two ends; come off into mother socket 10 and public plug 20, there is effect of protective effect and USB connector is separated.

While preparing USB connector to be separated into mother socket 10 and public plug 20, please refer to the drawing 4, because therefore fixed axis 16 is fixedly supported to interior formation one rotating shaft of plastics housing 12, therefore button 13 is executed to the power pressing down, upwards mention the hook part 15 of described U-shaped lamellar body 14 front ends, the now no longer clip of hooked part 15 of described fixing hole 23, separates the two fastening structure.Therefore public plug 20 is imposed to a strength backward, thus can delamination the two.

As shown in Figure 5, be the second embodiment of the present utility model, it comprises: a mother socket 10 and a public plug 20, in described mother socket 10, be provided with terminal base (not shown), and the insulation framework 19 that terminal base has been coated and plastics housing 12.The top of described mother socket 10 is provided with two and connects inner fixing hole 17, forms a fastening structure.Described public plug 20 is provided with terminal base 21, and by one take the shape of the letter U shape insulation framework 22 by terminal base 21 be placed in, the right position place of upper end and being coated.Side is coated by plastics housing 24 more afterwards with terminal base 21 for insulation framework 22, described plastics housing 24 tops are provided with a perforate, arrange for a button 25, and described button 25 bottoms are connected with a H shape lamellar body 26, two parallel lamellar body leading sections of described H shape lamellar body 26 are respectively provided with a hook part 27 to upper process, and two outsides of rear end are respectively provided with fixed axis 28, after being respectively arranged with a limit spring 29 on it, close with plastics housing 24 axles again, make H shape lamellar body 26 can be resisted against plastics housing 24 under normality, complete the assembler of fastening structure.

When combination, same insulation framework 22 and the terminal base 21 that public plug 20 is exposed, insert in the opening of mother socket 10, until the hook part 27 of H shape lamellar body 26 front ends touches the opening of mother socket 10, and opening is advanced along the gradient of hook part 27, indirectly described H shape lamellar body 26 is executed to a downforce, when mother socket 10 is shifted bottom onto, the hook part 27 of described H shape lamellar body 26 front ends just enters in the fixing hole 17 of mother socket 10, completes the fastening of two fastening structures.So, in the time pullling because of carelessness the line body of described USB connector, due to hook part 27 hook be butted on fixing hole 17 in, USB connector do not separated and there is protection effect.When preparation separates described USB connector, because therefore fixed axis 28 is fixedly supported to interior formation one rotating shaft of plastics housing 24, so only need to press described button 25, make the 26 stressed declines of H shape lamellar body, related make hook part 27 not at clip at fixing hole 17, two fastening structures are separated, facilitate mother socket 10 to exit backward public plug 20.

Quite popular MP3 player or portable disk now, due to quite small and exquisite, for preventing doing to lose, user can connect a necklace and be placed on neck, please refer to the drawing 6, the connector of described portable disk 40 is provided with terminal base 42, and by an insulation framework 43 that takes the shape of the letter U shape, terminal base 42 is coated, and insulation framework 43 is coated by plastics housing 44 more afterwards with terminal base 42, described plastics housing 44 tops are provided with a perforate, arrange for a button 45, and described button 45 bottoms are connected with a H shape lamellar body 46, two parallel lamellar body leading sections of described H shape lamellar body 46 are respectively provided with a hook part 47 to upper process, and two outsides of rear end are respectively provided with fixed axis 48, after being respectively arranged with a limit spring 49 on it, close with plastics housing 44 axles again, complete the composition of fastening structure, described over cap 50 is for the connector that is sleeved on portable disk 40, and described over cap 50 is provided with and coordinates hook part 47 fixing hole 51 (being fastening structure) for its hook, and over cap 50 rear ends are directly provided with a necklace 52, by like this, more more protection portable disk 40, and can simplify the actor of pulling up portable disk.

The utility model is not limited to above-mentioned concrete execution mode, and those of ordinary skill in the art is from above-mentioned design, without performing creative labour, all conversion of having done, all drop on protection range of the present utility model in.
