Description
Technical field
The utility model relates to a kind of A type USB interfaces with computer-related equipment interface, especially anticollision.
Background technique
Universal serial bus, abbreviation USB are a kind of serial bus standards for connecting computer system and external equipment,
It is a kind of technical specification of input/output interface, is widely used in the information communications product such as PC and mobile device.
The principal mode of USB interface has Type A, Type B and Micro USB, and wherein the interface of Type A, that is, A type is most widely used
's.In recent years, although Type C interface rises, due to cost and used equipment compatibility etc., the interface of A type still will be grown
Temporally it is used as mainstream interface.
Existing USB interface usually is led to connect unstable, light then male connector when in use due to male connector equipment by collision
Interface deformation, heavy then read and write process interrupt, corrupted data.Moreover, it since male connector and female lack apparent mark, uses
Family is frequently necessary to overturning 2 times even 3 times when using conventional A type interface to be inserted into, this can seriously reduce usage experience.Cause
This, existing A type USB interface there is a problem of lacking anti-collision capacity, protect data performance poor and be easy anti-inserted.
Utility model content
The purpose of the utility model is to provide the USB interfaces of anticollision.The utility model has anti-collision capacity, can
Effectively prevent read-write process to be interrupted by collision, thus protect data performance it is preferable, and the utility model be not easy it is anti-inserted.
The technical solution of the utility model includes: the USB interface of anticollision, including with female slot guide post disposed in parallel, lead
Sliding block and reset spring are arranged on column, one end of sliding block has the protrusion for protruding into slot, and the other end of sliding block is hinged with driving
Bar, drive rod middle part are equipped with shaft, and the other end of drive rod opposing slider is connected with cradling piece, and the end of cradling piece is equipped with shield
Piece；
It further include two hinged interlocking bar, an interlocking bar is hinged with drive rod, and hinge joint setting is leaned in shaft
The side of nearly sliding block, another interlocking bar are connected with cradling piece.
In the USB interface of anticollision above-mentioned, the guide post, sliding block, reset spring, drive rod, cradling piece, bluff piece and
Interlocking bar is two sides that are pairs of and being symmetricly set on female slot.
In the USB interface of anticollision above-mentioned, the reset spring total elastic force when in a compressed state is no more than
25N。
In the USB interface of anticollision above-mentioned, the female slot is inwardly collapsed.
In the USB interface of anticollision above-mentioned, the drive rod is connected with cradling piece by slide bar sliding groove structure.
In the USB interface of anticollision above-mentioned, the male connector interface cooperated with USB interface, lateral surface is equipped with mark convex block；
The female outer end face is equipped with marker, and marker is equipped with the gap with mark convex block cooperation.
Compared with prior art, the utility model drives the structure of connecting rod by sliding block, pushes and slides in male connector insertion slot
When block, bluff piece stretch out, protect male connector equipment, prevent its caused to connect by collision it is unstable, to ensure that read-write process, in turn
Protect data.Meanwhile the utility model prevented by the mark convex block and marker of male connector and female it is anti-inserted.The utility model
Anti-plug antistructure prompted in tactile and the aspect of vision two, the effect of inverse inserting-preventing is more preferable.
Further, the link mechanism design of the utility model is reasonable, and spring force has a certain range, in conjunction with
The structure that female slot collapses, makes the utility model meet the requirement of contact engaging and separating force.
To sum up, the utility model has anti-collision capacity, and read-write process can be effectively prevent to be interrupted by collision, thus protects number
According to better performances, and the utility model be not easy it is anti-inserted.

Specific embodiment
Below with reference to embodiment, the utility model is described in further detail, but be not intended as to the utility model limit according to
According to.
Embodiment: the USB interface of anticollision, including with female slot guide post 10 disposed in parallel, be arranged on guide post 10
Sliding block 20 and reset spring 21, one end of sliding block 20 have the protrusion 22 for protruding into slot, and the other end of sliding block 20 is hinged with driving
Bar 30, shaft 31 is equipped in the middle part of drive rod 30, and the other end of 30 opposing slider 20 of drive rod is connected with cradling piece 40, cradling piece 40
End be equipped with bluff piece 41；It further include two hinged interlocking bar 32, an interlocking bar 32 is hinged with drive rod 30, and hinged
Shaft 31 is arranged in close to the side of sliding block 20 in point, and another interlocking bar 32 is connected with cradling piece 40.
Guide post 10, sliding block 20, reset spring 21, drive rod 30, cradling piece 40, bluff piece 41 and the interlocking bar 32 be
Two sides that are pairs of and being symmetricly set on female slot.
The reset spring 21 total elastic force when in a compressed state is no more than 25N.
The female slot inwardly collapses.
The drive rod 30 is connected with cradling piece 40 by slide bar sliding groove structure.
With 50 interface of male connector of USB interface cooperation, lateral surface is equipped with mark convex block 51；The female outer end face is equipped with
Marker 60, marker 60 are equipped with the gap 61 cooperated with mark convex block 51.
Working principle:
The insertion of male connector 50 can be slided by convex block band movable slider 20, and the sliding of sliding block 20 drives drive rod 30 to rotate, driving
Bar 30, cradling piece 40 and interlocking bar 32 form a quadrilateral structure, and the rotation of drive rod 30 drives cradling piece 40 protruding, branch
Equipment of the bluff piece 41 of 40 end of hack lever to protect male connector 50, prevents it to be collided.Settable soft buffering on bluff piece 41
Pad, bluff piece 41 is not direct and 50 equipment of male connector contacts, and avoids increasing withdrawal force.
When male connector 50 is extracted, sliding block 20 resets under the drive of reset spring 21, and then each bar resets therewith.Due to
The contact engaging and separating force standard of USB interface is, when insertion should not exceed 35N, no less than 10N when extraction.The utility model is to contact engaging and separating force
It influences maximum to be sliding block 20 by top to extreme position, total elastic force of spring effect at this time should be less than 25N, and normally real in function
In the case where existing, spring force is the smaller the better.
The gathering of female slot can increase contact engaging and separating force, successively carry out the elastic force of partial offset spring.
Moreover, by the mark convex block 51 in male connector 50 and the marker 60 in female, the utility model is being connected
When can effectively distinguish front and back sides and be also just not easy anti-inserted without deliberately going to see the position of plastic sheet in interface, improve user
Experience.
