Description
Technical field
The utility model relates to a kind of interface dust cap.
Background technology
Along with the fast development of science and technology, people's living standard is more and more higher, and the quantity of household electrical appliance or office appliance is also more and more.Along with the continual renovation of chip technology, interconnecting communication between the electrical equipment becomes possibility, and the quantity of interconnective interface and spare interface or expansion interface is also more and more between the electrical equipment.Being extensive use of of electrical equipment can produce a large amount of static, this just cause electronic device especially the exposed metal/bare metal part can adsorb a large amount of dusts, even often sweep, because per-interface space is narrow and small, also easy cleaning is unclean, still can't avoid the existence of dust, like this, not only cause the short circuit of electronic device pins easily, serious, can cause fire, also can when connecting use, cause loose contact, influence the normal use of interface.
Summary of the invention
The technical problems to be solved in the utility model be at above-mentioned deficiency provide a kind of rational in infrastructure, can prevent that dust from entering, and interface dust cap easy to use.
For solving the problems of the technologies described above, the design feature of this interface dust cap is: comprise the elasticity cock body that cooperates with interface inner chamber plug-in mounting, the cock body outer end is installed with the cover plate that covers the interface end, cover plate and interface adjacent face limit portion are provided with the elasticity bulge loop that covers interface, and cover plate is provided with the grips that cock body is inserted or extracts interface.
The interface dust cap of this structure realizes being difficult for electric shock, safe by the elasticity packed configuration.
The elasticity packed configuration mainly comprises cock body and the cover plate that is fixed together, and the overall dimension of cock body matches with interface inwall size, and cock body has elasticity, like this, cock body can be filled in the interface inner chamber, because cock body is flexible, so be difficult in interface, deviating from, played the effect of locking positioning; The overall dimension of cover plate is bigger slightly than the overall dimension of cock body, and cover plate and cock body exterior contour are step-like, and like this, after cock body was filled in the interface, cover plate just can all cover the interface outer end, has played the effect of isolating interface and extraneous air.Cover plate and interface adjacent face limit portion are provided with an elasticity bulge loop, after filling in cock body in the interface, cover plate can be pressed on bulge loop on the casing for electric appliances of mounting interface, because bulge loop has elasticity, therefore the seal isolation better effects if can effectively avoid dust to enter in the interface.Also be provided with grips on the cover plate, the main effect of grips is to be convenient for people to control, and when needs take off this interface dust cap, controls grips and cock body is pulled out in the interface gets final product, and is very convenient.
As improvement, cock body is a hollow-core construction, and the cock body inner chamber matches with interface middle part plug connector profile.
Cock body is set to hollow-core construction, can make cock body insert the middle part when being provided with the interface of plug connector, and the jam-pack degree of cock body and interface is higher, difficult drop-off, and also hollow-core construction can make this interface dust cover materials more economize, and cost is lower.
As improvement, the cock body lateral surface is provided with the wedge shape boss.
The wedge shape boss is set on the lateral surface of cock body, can increases the frictional force of cock body lateral surface and interface medial surface, help to strengthen the jam-pack degree, prevent to use for a long time the back cock body to deviate from.
As a kind of implementation, described grips is the groove that is arranged on the cover plate side.
In the present embodiment, groove is set, can stays the space of controlling cover plate for people in the cover plate side, convenient when controlling.
As second kind of implementation, described grips comprises the retainer ring that is installed on the cover plate outer face, is connected with draw ring on the retainer ring.
In the present embodiment, set firmly retainer ring on the cover plate outer face, and connect draw ring on retainer ring, the relative cover plate of retainer ring is motionless, and draw ring can be movable, in the time of need extracting this interface dust cap, catches on the draw ring pulling with hand and gets final product, and is very convenient.
As the third implementation, described grips comprises the hinge cover that is installed on the cover plate outer face, is fitted with the hinge ring in the hinge cover.
Present embodiment will be cut with scissors ring in hinged way and will be connected on the cover plate outer face by hinge cover, and under the nature, the hinge ring will be concordant with the cover plate outer face under action of gravity, can protruding not stand out, during use, catch on the hinge ring with hand and cock body is pulled out will get final product, and will be very convenient.
As improvement, the cover plate avris is connected with the locking head that is locked together with the interface shell by connection cord.
On the cover board locking head is set by connection cord, locking head can with the device housings fixing and locking together, like this, no matter cock body is seated in the interface cavity, still in the interface cavity, extract, all will be connected on the device housings, can effectively avoid losing by connection cord and locking head, insert when using again and get final product next time, very convenient.
In sum, adopt the interface dust cap of this structure, rational in infrastructure, can prevent that dust from entering, and easy to use, be adapted at using on the various electrical equipment, be particluarly suitable for using on computer, the laptop computer, can effectively prevent dust accretions, the short circuit accident of avoiding static to cause.
