Description

A kind of USB double-side socket

Technical field

The utility model relates to socket, relates to specifically a kind of USB double-side socket.

Background technology

USB is the abbreviation of English Universal Serial Bus, and Chinese implication is " USB ".In recent years, support that the PC of USB and equipment are day by day universal, use USB head is inserted, the external equipment of socket is also gradually abundant, as keyboard, mouse, printer, digital camera, scanner, game machine, vision facilities etc.

Existing USB socket structure, its male joint and female joint all can only plug with fixed-direction, if will be wherein after a USB joint upset, be limited to baffle plate in joint or the constraint of joint geometry, and two joints cannot normally be pegged graft, and can not form signal transmission.The object that arranges of this baffle plate and joint geometry constraint is can correctly form corresponding contact with the even number conduction end points in female joint in order to ensure the even number conduction end points in male joint.In the time that practical operation is applied, the joint comparison operation before correct pegging graft has been brought larger inconvenience to user.

Separately, for some USB device, if adopt the USB socket that only can peg graft with single direction, this device will cannot normally insert because of the problem of volume.For example, for this memory card with USB joint, if adopt single direction to be plugged in the connectivity port on register face, card lateral margin may be subject to stopping of other plugs and cannot make USB joint insert smoothly, if now can be by after memory card upset, thereby making USB joint change adopting another side to insert connectivity port contact produces signal transmission, just can head it off, the USB socket as can be seen here with double-side plug-in function can improve the convenience of device operation really.

USB socket schematic diagram of the prior art as shown in Figure 2, is provided with four terminals at its socket subordinate end, and centre is provided with tongue mouth 11.USB plug can only select a kind of direction could insert USB socket, if direction and USB socket are inconsistent, can insert to enter, and the terminal that can damage in USB plug.In addition on the one hand, in our operating process, often can encounter USB plug and USB socket does not connect, illustrate that USB plug contacts unstable with USB socket.Especially in the time of download file, once not connect, can cause file transfer to be interrupted, then while reinserting USB socket, reconnect again download, very inconvenient.

Utility model content

For the deficiency in above-mentioned technology, the utility model provides a kind of USB double-side socket, these upper and lower two ends of socket outlet portion are all provided with reverse splicing ear, plug is attached thereto, and its fixed effect, slotting getting have all obtained very large improvement in effect, conductivity, data transmission stability, useful life etc.

For solving the problems of the technologies described above, the utility model is realized by following scheme: a kind of USB double-side socket, it comprises terminal shell, the center of terminal shell is provided with the USB socket portion that connects power supply and holding wire, this USB socket portion comprises terminal and tongue mouth, in the groove of USB socket portion, the upper and lower two ends of tongue mouth are provided with symmetrical splicing ear, the splicing ear on top comprises four signal terminals, be followed successively by from left to right: power source supply end that operating voltage is provided, D+ signal terminal, D-signal terminal, ground signalling terminal, arranging of bottom splicing ear arranged for the reverse of splicing ear on top, the described tongue mouth left and right sides is provided with can be by screens fixing USB plug.

Further, the upper and lower two ends of described groove are provided with symmetrical shell fragment.

Further, being arranged in groove of described screens symmetry, is connected with groove sidewall is oblique respectively.

Further, described screens has two contrary pars convolutas, away from the reverse cell wall setting of pars convoluta arc tips of tie point.

The beneficial effects of the utility model are: 1. the splicing ear in USB notch is arranged to above-below direction, tongue mouth respectively has four identical contacts up and down, where no matter USB plug face up, all can insert smoothly in USB notch, and USB plug is contacted with the contact in USB notch, charge or transfer of data, user needn't worry to damage plug because USB plug is anti-inserted, extremely easy to use; 2. in USB notch, be also provided with screens, USB plug is inserted USB notch, and screens is equivalent to clamping device, by USB plug tightly be fixed on USB notch inside, avoid USB plug to rock and affect connection.Transfer of data stable, insert get conveniently, conduct electricity very well, good fixing effect, long service life.

Brief description of the drawings

Fig. 1 is the splicing ear schematic diagram that the utlity model has two-sided linkage function.

Fig. 2 is USB socket schematic diagram of the prior art.

Fig. 3 is that the utility model screens is installed on schematic diagram in USB notch.

Embodiment

Below in conjunction with accompanying drawing, the utility model is elaborated.

Embodiment: as shown in Figure 1, a kind of USB double-side socket, it comprises terminal shell 3, the center of terminal shell 3 is provided with the USB socket portion that connects power supply and holding wire, this USB socket portion comprises terminal and tongue mouth 11, it is characterized in that: in the groove 4 of USB socket portion, tongue mouth is provided with symmetrical splicing ear 1 in two ends Shang Xia 11, the splicing ear 1 on top comprises four signal terminals, be followed successively by from left to right: power source supply end that operating voltage is provided, D+ signal terminal, D-signal terminal, ground signalling terminal, arranging of bottom splicing ear 1 arranged for the reverse of splicing ear 1 on top, described tongue mouth 11 left and right sides are provided with can be by screens fixing USB plug 5, described groove is provided with symmetrical shell fragment 2 in two ends Shang Xia 4.

As shown in Figure 3, being arranged in groove 4 of described screens 5 symmetries, respectively with oblique connection of groove 4 sidewalls; Described screens 5 has two contrary pars convolutas, away from the reverse cell wall setting of pars convoluta arc tips of tie point.

Because the terminal of splicing ear upper and lower side is reverse arranging, in USB plug is inserted the utility model socket, no matter the upper part of plug is upper, or lower part is upper, the splicing ear 1 being positioned on metal terminal and the socket of top all can come in contact, no matter and make plug which side at upper insertion socket, can normally work.

Splicing ear 1 comprises respectively four terminals, corresponding Vbus, D+, D-, the GND of being defined as respectively, the metal terminal of plug be also with socket on terminal arrange equally, while inserting socket, metal terminal on plug can be set up correct annexation by the splicing ear with on socket one by one, and signal can normally be transmitted.

Two curved portions that screens 5 arranges, two curved portions have certain toughness, plug insertion socket, screens 5 curved portions tightly prop up the left and right wall of plug, and it is fixed in socket, can not rock, and therefore can better keep the connective stability of plug and socket.

The foregoing is only preferred implementation of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model specification and accompanying drawing content to do; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
