Embodiment
Fig. 1～Fig. 4 shows a kind of USB connector adapter sleeve 4A, and Fig. 5～Fig. 6 is connection and the application schematic diagram of the utility model on existing standard A type USB connector.USB connector adapter sleeve 4A is characterised in that it is the shell-like integrated through injection molding part that is sleeved on the belled position of the flat plug 51 of commercially available standard A type USB connector 5A and housing 52.Above-mentioned USB connector adapter sleeve 4A is provided with the housing through-hole 21 that is slidingly matched with this housing 52 with the housing link 2 that the housing 52 of standard A type USB connector 5A is connected, the USB connector adapter sleeve is provided with the plug through hole 13 that is slidingly matched with plug 51 with the plug link 1 that the flat plug 51 of standard A type USB connector is connected, and the connecting portion of housing through-hole 21 and plug through hole 13 forms the ring Zhou Taijie confined planes 3 of block standard A type USB connector housing end face 53; Two flat horizontal surfaces of the corresponding flat shell of housing through-hole 21 inwalls are provided with the elastic card claw 22 of symmetry; This elastic card claw 22 is the standalone elastic sheets that formed by the two bar shaped gap of offering on the two flat horizontal surfaces edge, hole partly of corresponding flat shell 52 on housing through-hole 21 inwalls 24 that are parallel to USB connector adapter sleeve center line, and the sheet end is provided with card rib 23.The two sides of plug link 1 corresponding flat plug 51 are arranged in plug link end face and form the inclined side that extends end face 12, be arranged with locking pin 11 on the two extension end faces 12, locking pin is provided with by possessing two dops that the hemisphere face body constitutes that the gap is provided with.Plug link 1 is connected with electronic equipment by locking pin 11.
As Fig. 5～shown in Figure 6, plug 51 with standard A type USB connector during use passes in the housing through-hole 21 insertion plug through holes 13 of USB connector adapter sleeve 4A, ring Zhou Taijie confined planes 3 blocks that are provided with on the USB connector adapter sleeve are lived standard A type USB connector housing end face 53, and are blocked by two flat horizontal surfaces of the elastic card claw 22 of being with card rib 23 with the flat shell 52 of standard A type USB connector.At this moment, USB connector adapter sleeve chucking is sleeved on the belled position of flat plug 51 and housing 52, then, standard A type USB connector plug 51 is inserted in the USB jack of Electronic equipment panel 6, and snap in by locking pin 11 in the hole clipping of corresponding setting on the Electronic equipment panel, make A type USB connector secure lock in the electronic equipment jack.The above-mentioned adapter sleeve that is used for standard A type USB connector be applicable to use standard A type USB interface and to data transmission bauds and data accuracy require height, can not accidental interruption, the equipment that do not allow the packet loss phenomenon to take place.Adopt the utility model can effectively prevent to cause bad phenomenon such as connecting loosening data transmission fails because of external force such as twisting, vibrate, pull; As shown in Figure 6, because the installed surface that contacts with Electronic equipment panel of this USB connector adapter sleeve is provided with the contact area that extension end face 12 has increased itself and device panel, adopt two ends locking pin structure in addition, after using this USB connector adapter sleeve, effectively limited the degree of freedom of the plug upper and lower, left and right activity of standard A type USB connector, connect close and firm, therefore it can very effectively be prevented because unnecessary the moving that the external force effect produces, and then fundamentally solved the self structure deficiency of USB connected mode, its performance has been carried out reasonable optimizing.
In addition, adopt usb protocol to carry out high speed data transfer, requirement to the USB line is also very high, in case thread-changing or change structure may will cause performance difference, and then influence the accuracy of transfer of data, the design feature of this reinforcing cover makes its electric property that does not change data wire fully, only can finish by simple suit.
For adapting to the hot swap characteristics of USB connector, above-mentioned USB connector adapter sleeve adopts wear-resisting, and fatigue resistance is good, and on-deformable nylon material such as nylon 1010 are made, and can adapt to the frequent handling characteristics of USB connector plug number of times fully.
As Fig. 7-shown in Figure 8, be the application schematic diagram of the utility model on the MiniUSB connector.Fig. 7 is a kind of and the small-sized MiniIC card of USB connector 5B integral type, Fig. 8 is the boxlike IC-card of the external IC-card card reader 7 of MiniUSB connector 5B, wherein USB connector adapter sleeve 4B and USB connector adapter sleeve 4A structure and material are identical, just dimensions is little, be suitable for and the supporting use of microminiature MiniUSB connector, concrete plug-in mounting and fastening principle are also identical.
The IC-card of above-mentioned two kinds of forms is very typical hardware based authentication means in secure communication, use extremely wide, but since MiniIC card volume little, weak strength; The joint of boxlike IC-card card reader 7 is a line-connection type, can move easily, and therefore careless bump and slight tearing are easy to fracture, and cause damage, when serious even may the interior motherboard of damage equipment, causes complete machine to be scrapped.The USB connector adapter sleeve is installed on the MiniUSB connector, guarantee its tight contact, install in the back insertion privacy device and get final product, only needing make a call in device panel 8 relevant positions two very little installing holes is used to snap in locking pin 11 and can realizes being fastenedly connected, dismounting is very convenient, the product versatility is good, and protection effect is very obvious.
In sum, this USB connector adapter sleeve is front and back open type sleeve shaped structures, and is easy for installation, utilizes the design feature of USB attachment plug of standard A type and MiniUSB equipment self to carry out the location of front and back position, accurately cooperate with standard plug or connection device shell, become one; Adopt the structure of extending end face and both-end locking pin with the link of equipment, can closely be connected, accomplish that structurally size is suitable with device panel, do not influence the USB plug insertion depth fully, do not influence electric property, it is fixing to guarantee that this device only plays reinforcement, anti-disturbance, against shock, effects such as anticollision, are really accomplished to dismantle at any time without any change to equipment mainboard and electric property, be convenient for changing, product is general.
The above only is a preferred embodiment of the present utility model, is not shape material of the present utility model and structure are done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
