The USB interface female seat of side belt switch
Technical field:
The utility model relates to a kind of USB interface female seat, relates in particular to the USB interface female seat of a kind of side belt switch.
Background technology:
Along with the unification of charger for mobile phone interface, many portable electronic products such as mobile phone, MP4, digital camera can be inserted the female seat of band USB charge power supply output and charge by the data wire of USB interface; And the power supply of USB interface female seat is mainly directly connected by the 220V-110V attaching plug, there is not switching device, people are at the cellular phone power supplies of substituting the bad for the good, if just pull out USB charging output interface, do not pull out the plug of USB charging input power supply, the USB charger will be worked always, promptly waste electric energy easily, cause the USB charging circuit aging again easily, make troubles to life.
Summary of the invention:
The utility model purpose is to provide the USB interface female seat of a kind of side belt switch, in the time of can be by the grafting USB interface, controls the input power supply or the data-signal of USB interface female seat automatically.
The utility model is achieved through the following technical solutions:
A kind of USB interface female seat of belt switch, the USB interface female seat that comprises standard, it is characterized in that USB interface female seat one side is provided with through hole, USB interface female seat exterior lateral sides is provided with a switch, a sliding-tongue is set on the switch, one end of described sliding-tongue stretches through in the inner side of USB interface female seat by the through hole of USB interface female seat.
Described sliding-tongue stretches through and is arranged to inclined-plane or cambered surface at an end of USB interface female seat inside, and the other end passes USB interface female seat side, and is continuous with the electrode of switch inside.
Described sliding-tongue links to each other with the same shell fragment of an end that switch links to each other.
Described switching circuit links to each other with USB charge power supply input, the power supply of control USB charge power supply input.
The shell fragment of described switch can also adopt spring structure.
The advantage that this use is novel:
The utility model is simple in structure, safe and reliable, volume is little, substantially need not change the inner primary structure of generic USB socket female seat, when just can be implemented in the grafting USB interface, control the input power supply or the data-signal of USB interface female seat automatically, as be applied to the USB charger, can effectively prolong the useful life of charging circuit, energy-conserving and environment-protective again; As when being applied to the usb data signal, will reduce the time interference to data-signal without the USB interface female seat.

Embodiment:
Below in conjunction with accompanying drawing utility model is further specified:
See also accompanying drawing 1,
A kind of USB interface female seat of belt switch, the USB interface female seat that comprises standard, it is characterized in that USB interface female seat 1 one sides are provided with through hole 101, USB interface female seat 1 one side inside are provided with sliding-tongue 201, USB interface female seat 1 exterior lateral sides is provided with switch 2, and described sliding-tongue 201 links to each other with switch 2 by USB interface female seat 1 one side through hole 101.
Described sliding-tongue 201 is arranged to inclined-plane or cambered surface at the inner end 202,203 of USB interface female seat, and the other end passes the through hole 101 of USB interface female seat 1 side, links to each other with the switch 2 that is arranged on USB interface female seat 1 exterior side wall.
Described sliding-tongue 201 links to each other with the same shell fragment 207 of an end that switch links to each other.
See also accompanying drawing two:
Operation principle of the present utility model is as follows: the sliding-tongue 201 that is located at USB interface female seat 1 one side inside, owing to be subjected to the effect of the shell fragment 207 of electric conducting material making, the shell fragment made from electric conducting material 208 separates, electrode contacts 205 and electrode contacts 206 also are in off-state, make switch 2 be in off-position in normality; When USB plug 5 is inserted USB interface female seat 1, stretch through at the sliding-tongue 201 of USB interface female seat 1 one side inside, be subjected to the side-thrust effect of USB plug 5, promote sliding-tongue 201 to USB interface female seat 1 an outside side shifting, drive electrode contacts 205 with electrode contacts 206 contacts, make switch 2 be in conducting state.
After extracting USB plug 5, stretch through at the sliding-tongue of USB interface female seat 1 one side inside, under the active force of shell fragment 207, promote electrode contacts 205 and electrode contacts 206 and be in off-state, make switch 1 be in off-position again.
The lead 209,210 of described switch 2 links to each other with USB charge power supply input, the power supply of control USB charge power supply input.
See also accompanying drawing three
Described switch 2 structures can also adopt spring structure 211, and the lead 209 of switch 2 can adopt flexible cord 212 to link to each other with electrode contacts 205.
In sum, the utility model makes things convenient for the user that the charging of the portable electronic products of mobile phone is used, and realizes " zero energy " standby, and " promptly insert and promptly open " is simple in structure, volume is little, and is easy to use; So both effectively prolonged the useful life of USB charging circuit, energy-conserving and environment-protective again; Meeting under the prerequisite of utility model patent, the spy files an application in accordance with the law.
