Abstract
The utility model provides a USB interface with prevent reverse plug function, including the shell of the female head of USB, the female head of installation, this shell embeds the recess, the recess comprises two parts: the spread groove, the female head of built -in above -mentioned USB, prevent the reverse plug groove, this USB interface with prevent reverse plug function of length and the prior art that are lighter than the spread groove with spread groove even as an organic whole and its length compare, and the difference of USB positive and negative can be felt with the hand in the global design of interface, has greatly made things convenient for the operation, saves operating time, has made things convenient for test, interface edge adopts the structure that leans out 45 degrees angles, no matter it can not blocked to insert USB from which direction all around, damages the contact point, is favorable to the protection at USB contact point and interface edge, and the practicality is strong, and application scope is extensive, easily the popularization.
Description
Technical field
The utility model relates to computer hardware equipment technical field, specifically simple, the USB interface with inverse plugging function of a kind of structure.
Background technology
USB interface is the interface often used in server test work.Most USB interface of server, all at the afterbody of cabinet, when inserting USBkey or usb line, often need movable chassis or cabinet afterbody of stretching forward look at and inserted by USB.Nonetheless, the rectangle design that USB interface is unalterable, still makes to occur mixing up positive and negative when slotting USB, needs repeated multiple times situation of attempting inserting.Inconvenience has been with in this use not being only USB, and the trial of repeatedly misfitting is inserted and all can be caused damage to USB contact point and egress edge, of a specified duration just there will be that USB port easily loosens, the phenomenon such as easily come off, and shortens the useful life of USB port.In order to overcome the above problems, now provide a kind of USB interface with inverse plugging function.
Summary of the invention
Technical assignment of the present utility model solves the deficiencies in the prior art, provides the USB interface with inverse plugging function that a kind of structure is simple, result of use is desirable.
The technical solution of the utility model realizes in the following manner, a kind of USB interface with inverse plugging function, and comprise USB female, install the shell of female, the built-in groove of this shell, described groove is made up of two parts: link slot, built-in above-mentioned USB female; Counnter attack slot, is connected as a single entity with link slot and its length is less than the length of link slot.
Described link slot is rectangular-shaped groove, and counnter attack slot is trapezoidal shape groove and is arranged on the upside of this link slot or downside.
The rectangular trapezoidal shape of described counnter attack slot, and its right-angle side coincides with a side of link slot and is connected, upside or the lower edge of hypotenuse and link slot are connected.
The outer ledge that described link slot, counnter attack slot are connected with the USB device of band USB male joint is outward-dipping shape, and its angle of inclination is 225 degree.
In sum, the beneficial effect that the utility model is compared with prior art produced is:
A kind of USB interface with inverse plugging function of the present utility model has the features such as structure is simple, easy to use, novel, the global design of interface can contact the difference of USB positive and negative by feel, be very easy to operation, save the operating time, facilitate test job; Egress edge adopts the structure of outward-dipping miter angle, all can not be snapped to, damage contact point, be conducive to the protection of USB contact point and egress edge no matter insert USB from which direction of surrounding, practical, applied widely, is easy to promote.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is the right view of Fig. 1.
Mark in accompanying drawing represents respectively:
1, shell, 2, USB female, 3, link slot, 4, counnter attack slot.
Embodiment
Below in conjunction with accompanying drawing, a kind of USB interface with inverse plugging function of the present utility model is described in detail below.
As shown in accompanying drawing 1, Fig. 2, a kind of USB interface with inverse plugging function is now provided, comprise USB female 2, the shell 1 of female is installed, the built-in groove of this shell 1, described groove is made up of two parts: link slot 3, built-in above-mentioned USB female 2, this link slot 3 can be used for connecting generic USB equipment common at present; Counnter attack slot 4, is connected as a single entity with link slot 3 and its length is less than the length of link slot 3, and this counnter attack slot 4 mainly prevents USB device anti-inserted, can be used for the USB device similar with whole interface structure.
Described link slot 3 is in rectangular-shaped groove, and counnter attack slot 4 is in trapezoidal shape groove and be arranged on the upside of this link slot 3 or downside.
Described counnter attack slot 4 at right angles trapezoidal shape, and its right-angle side coincides with a side of link slot 3 and is connected, upside or the lower edge of hypotenuse and link slot 3 are connected.
The outer ledge that described link slot 3, counnter attack slot 4 are connected with the USB device of band USB male joint is outward-dipping shape, and its angle of inclination is 225 degree.
In the utility model, link slot 3 can contact the different of USB interface positive and negative by feel from the design of counnter attack slot 4, does not need to confirm, for server, even the USB interface of machine box for server afterbody also can correctly be inserted easily with eyes.And egress edge is also designed to stiff an angle of 90 degrees unlike traditional USB interface, but to become surrounding be miter angle, all can not be snapped to, damage contact point no matter insert USB from which direction of surrounding.In a word, this design both facilitated operation, was conducive to again the protection of USB contact point and egress edge.
Above execution mode is only for illustration of the utility model, and be not limitation of the utility model, the those of ordinary skill of relevant technical field, without departing from the spirit and scope of the present invention, can also make a variety of changes and modification, therefore all equivalent technical schemes also belong to category of the present utility model.
