Embodiment

Fig. 1 is the stereo appearance figure of existing universal serial bus connector, and its structure is as mentioned above so repeat no more in this.

Please join Fig. 2 and Fig. 3, be the utility model first embodiment, comprise a female plug seat 10 and a public plug 20, this female plug seat 10 is provided with terminal base 11, coat an insulation framework 19 and a plastics housing 12 in terminal base 11 outer rims, the top of this two housing (or bottom) is provided with a through hole that runs through, establish for 13 groups for a button, these button 13 bottoms are connected with a U-shaped lamellar body 14, and two ends of this U-shaped lamellar body 14 are provided with hook part 15, and each prominent fixed axis 16 of establishing of the middle section, two outsides of U-shaped lamellar body 14, respectively be arranged with limit spring 18 on this two fixed axis 16, make the hook part 15 of U-shaped lamellar body 14 ends can be butted on the terminal base 11, and with its keeping parallelism, to constitute a complete fastening structure.

The structure of this public plug 20 is identical with existing structure, mainly be provided with terminal base 21, coat an insulation framework 22 in terminal base 21 outer rims, offer two fixing holes 23 on the insulation framework 22 of these terminal base 21 tops, by this forming corresponding fastening structure, and the latter half of of terminal base 21 and insulation framework 22 coats with plastics housing 24.

Please join Fig. 3 again, in conjunction with the time, the insulation framework 22 that directly public plug 20 is exposed is inserted the opening of the plastics housing 12 of female plug seat 10, at this moment, these insulation framework 22 front ends are along the gradient of U-shaped lamellar body 14 hook parts 15, and by the elastic force of limit spring 18 and make hook part 15 be insulated framework 22 jack-up, and walking thereon along the push-on force of insulation framework 22, shift the bottom onto up to this insulation framework 22, and collude in the fixing hole 23 that is stuck in insulation framework 22 hook part 15 of U-shaped lamellar body 14, make the fastening structure of the two fasten mutually, and make the terminal base 11 of the two, 21 are in contact with one another, and finish the assembling of universal serial bus connector.

Thus; the universal serial bus connector finished of assembling as touched because of carelessness, when pullling; because the fastening structure of the two fastens (collude in the fixing hole 23 that is stuck on the public plug 20 insulation frameworks 22 hook part 15 that is U-shaped lamellar body 14 front ends in the female plug seat 10) mutually; so can be because of not pullling the line body of universal serial bus connector 1 two ends; come off into female plug seat 10 and public plug 20, have protective effect and universal serial bus connector is separated.

When desire is separated into female plug seat 10 and public plug 20 with universal serial bus connector, please join Fig. 4, because of fixed axis 16 is fixedly supported in the plastics housing 12, so form a rotating shaft, therefore button 13 is executed a power that presses down, then upwards mention the hook part 15 of these U-shaped lamellar body 14 front ends, this fixing hole 23 this moment clip of hooked part 15 no longer, the two fastening structure is separated, therefore public plug 20 is imposed backward a strength, so but delamination the two.

Please join Fig. 5, be second embodiment of the present utility model, comprise: a female plug seat 10 and a public plug 20, be provided with terminal base (scheming not shown) in this female plug seat 10, and insulation framework 19 and plastics housing 12 that terminal base has been coated, and the top of this female plug seat 10 is provided with two and connects inner fixing hole 17, forms a fastening structure; This public plug 20 is provided with terminal base 21, and terminal base 21 is placed by an insulation framework 22 that is the Qian shape, the right position place of upper end and with its coating, and insulation framework 22 is coated by plastics housing 24 with the rear of terminal base 21 again, these plastics housing 24 tops are provided with a perforate, be provided with for a button 25, and these button 25 bottoms are connected with a H shape lamellar body 26, two parallel lamellar body leading sections of this H shape lamellar body 26 respectively are provided with a hook part 27 to upper process, and two outsides of rear end respectively are provided with fixed axis 28, close with 24 of plastics housings again after respectively being arranged with a limit spring 29 on it, make H shape lamellar body 26 under normality, can be resisted against plastics housing 24, finish the assembling of fastening structure.

During combination, same insulation framework 22 and the terminal base 21 that public plug 20 is exposed, insert in the opening of female plug seat 10, touch the opening of female plug seat 10 up to the hook part 27 of H shape lamellar body 26 front ends, and make opening along the hook part 27 gradient advance, indirectly this H shape lamellar body 26 is executed a downforce, treat that female plug seat 10 shifts the bottom onto, the hook part 27 of these H shape lamellar body 26 front ends just enters in the fixing hole 17 of female plug seat 10, finishes the fastening of two fastening structures; So, when pullling the line body of this universal serial bus connector because of carelessness,, universal serial bus connector is not separated and have the protection effect because hook part 27 colludes and be butted among the fixing hole 17; When desire is separated this universal serial bus connector, because fixed axis 28 is fixedly supported in the plastics housing 24 so form a rotating shaft, only need push this button 25, make the 26 stressed declines of H shape lamellar body, related make hook part 27 no longer clip in fixing hole 17, two fastening structures are separated, make things convenient for female plug seat 10 to withdraw from public plug 20 backward.

Quite popular now MP3 player or walkman, because it is quite small and exquisite, for preventing to lose, the user can connect a necklace and be placed on the neck, please join Fig. 6, the connector of this walkman 40 is provided with terminal base 42, and terminal base 42 is coated by an insulation framework 43 that is the Qian shape, and insulation framework 43 is coated by plastics housing 44 with the rear of terminal base 42 again, these plastics housing 44 tops are provided with a perforate, be provided with for a button 45, and these button 45 bottoms are connected with a H shape lamellar body 46, and two parallel lamellar body leading sections of this H shape lamellar body 46 respectively are provided with one to the hook part 47 of upper process, and two outsides of rear end respectively are provided with fixed axis 48, close with 44 of plastics housings again after respectively being arranged with a limit spring 49 on it, finish the composition of fastening structure; This over cap 50 is for the connector that is sleeved on walkman 40, and this over cap 50 is provided with the fixing hole 51 (being fastening structure) that cooperates hook part 47 and supply its hook, and over cap 50 rear ends directly are provided with a necklace 52; Thus, more strengthen protection walkman 40, and can simplify the action of pulling up walkman.

The above only is preferred embodiment of the present utility model, and when can not be in order to limit the enforceable scope of the utility model, all habit in the personage of this industry obviously can be done to change and modification, all should be considered as not departing from flesh and blood of the present utility model.

In sum, the utility model really can accomplish the end in view, and a kind of protective effect that has is provided, and reason is not touched, pullled and the protective device of the universal serial bus connector that separates of coming off, and has practical value undoubtedly.
