Abstract
A kind of dustproof USB interface, comprise shell and USB contact, USB is located at contact outer shell bottom wall middle part, described shell aperture portion be provided with shell in the cross section dust plug that matches and can move back and forth along its inwall, dust plug is provided with the rectangular opening passing for USB contact, and described dust plug both sides are provided with guidance set; The beneficial effects of the utility model: the utility model is simple in structure, easy to use, without people's manual unlocking and close dust plug, improved user's experience.
Description
Technical field
The utility model relates to the design of USB interface equipment, is specifically related to a kind of dustproof USB interface.
Background technology
Usb is widely used in the interface of each large digital product as a kind of general interface, can be described as most popular a kind of interface now.The usb interface of take on computer is example, substantially on the general-purpose interface of computer, all can have about three or above usb interface.But large multi-USB interface is open type, will fall into for a long time a large amount of dust impacts and use, mostly adopt on the market the manual rubber dust-proof plug that covers and open, reduced user's experience.
Utility model content
It is a kind of simple in structure that the utility model provides, and without manually, has the dustproof USB interface that high user is experienced.
Solve the problems of the technologies described above the technical scheme of employing:
A kind of dustproof USB interface, comprise shell and USB contact, USB is located at contact outer shell bottom wall middle part, described shell aperture portion be provided with shell in the cross section dust plug that matches and can move back and forth along its inwall, dust plug is provided with the rectangular opening passing for USB contact, and described dust plug both sides are provided with guidance set.
As optimization: described guidance set comprise be located at shell both sides bar shaped pilot hole, be located at the band spring of dust plug both sides, described band spring embeds in pilot hole and slidably reciprocates along pilot hole, band spring below is provided with back-moving spring, and back-moving spring is fixedly mounted in the diapire section of stretching out.
As optimization: described shell both sides are provided with carries out spacing spring holding chamber to back-moving spring.
The beneficial effects of the utility model: the utility model is simple in structure, easy to use, without people's manual unlocking and close dust plug, improved user's experience.
Accompanying drawing explanation
Fig. 1 is blast structural representation of the present utility model;
In figure: 1, shell, 2, USB contact, 3, diapire, 4, dust plug, 5, rectangular opening, 6, band spring, 7, pilot hole, 8, back-moving spring, 9, spring holding chamber.
Embodiment
As shown in Figure 1, a kind of dustproof USB interface, comprise shell 1 and USB contact 2, shell 1 diapire 3 middle parts are located in USB contact 2, described shell 1 peristome is provided with the dust plug 4 that matches and can move back and forth along its inwall with the interior cross section of shell 1, dust plug 4 is provided with the rectangular opening 5 passing for USB contact 2, and described dust plug 4 both sides are provided with guidance set; Described guidance set comprise be located at shell 1 both sides bar shaped pilot hole 7, be located at the band spring 6 of dust plug 4 both sides, described band spring 6 embeds that pilot hole 7 is interior to slidably reciprocate along pilot hole 7, band spring 6 belows are provided with back-moving spring 8, and back-moving spring 8 is fixedly mounted in diapire 3 sections of stretching out; Described shell 1 both sides are provided with carries out spacing spring holding chamber 9 to back-moving spring 8.
When user does not insert external equipment, the peristome of dust plug in shell, has so just placed entering of dust, when user inserts after external equipment, and the bottom of dust plug in shell, external equipment contacts and starts working with USB contact.
