Description

A kind of interface card locator card fixing apparatus

Technical field

The utility model relates to a kind of interface card locator card fixing apparatus, can be with interface card location fixing locator card fixing apparatus on computers by easy eye-splice but refer in particular to a kind of nationality.

Background technology

General known interface card location fixing mode as shown in Figure 1, wherein interface card A utilizes the perforation C of the washer B top moulding at its rear, nationality is locked on the draw-in groove E by a screw D correspondence, except draw-in groove E need attack the system screw when the moulding earlier, remaining parts needs KTX LOCKING RECESS SCREWS D when loading and unloading, use inconvenience so cause, this structure makes the user feel beautifying inadequately of image appearance simultaneously, add the kenel of present computer casing, selecting for use of material to can reach light weight, easier machine-shaping and the recyclable requirement that utilizes again, most manufacturer adopts aluminium alloy to come moulding to make housing and draw-in groove E thereof, though aluminum alloy material forms advantages such as outward appearance is fine, its quality is softer, and unstable sense is arranged.And if adopt the solid mode locking interface card A of spiral shell, its regular meeting when bolt-lock to cause the tooth hole on the draw-in groove E to damage, often revolving lock 1 after twice, promptly can interface card can't be fixed because of the tooth hole is impaired.In addition, known interface card A is that nationality screw D single-point is fixed, and also has external output as this interface card and goes into function, when the user utilizes the connector plug, then can cause the situation of loosening or loose contact to take place because of the application of force is improper.

Summary of the invention

The purpose of this utility model is to overcome the defective of prior art, and a kind of novel interfacial fastening position clamping device is provided, to reach the stable effect that fixes interface card.

The purpose of this utility model is to adopt following technological means to realize: a kind of interface card locator card fixing apparatus, wherein its catch of interface card nationality is arranged on the draw-in groove of computer casing, and utilize press fastening device that interface card is fixed the location, it is characterized in that: the press fastening device correspondence is located at the distolateral of draw-in groove, comprise by a base and at least one slide block and combine, row are provided with some chutes above base, the front side of base has a header board, the bottom of header board forms an elasticity fixture block, the elasticity fixture block can pass through the frame hole of header board lower end, and extend to the rear of base, utilize the default convex clip of fixture block end face, the displacement of restriction slide block; The slide block correspondence is located at chute top and can appropriate slippage, and upper end of slide block has extended a cantilever, and inside then has a derby correspondence to be forced into and fixed one, the projection of derby root edge, the distolateral predetermined length of extended slide block; Nationality is made up of above-mentioned member, slide block is divided into the chute of base top, to form a press fastening device.The header board inboard of the base of described a kind of interface card locator card fixing apparatus forms a tenon, and tenon is used for moving ahead of position limiting slide block, and cooperates the convex clip on the fixture block that slide block is fixed the location.Corresponding inside of compeling people's slide block after the derby moulding of described a kind of interface card locator card fixing apparatus, be located in the derby in the cantilever, slightly protrude out the root edge of cantilever, when the passing cantilever presses this catch, provide cantilever the preferable holding capacity that presses strength and increase cantilever.

Compared with the prior art of the present utility model, its advantage shows:

First, utilization is passed slide block and it is pressed on baffle plate, can reach the effect that the interface card location is fixed, make the texture of product more superior, the utility model is not because of needing screw locking interface card simultaneously, also needn't on each draw-in groove, attack the system screw, the facility that can save man-hour effectively and promote assembling.

The second, as described in preceding paragraph, the utility model system is located with the sliding pressured interface card of pulling, so no matter which kind of material moulding draw-in groove uses, all can use with the utility model coupling, but also have non-damageable advantage.

The 3rd, the slide block system in the utility model utilizes its projection and cantilever that catch is pressed, except positioning function, also interface card there is chip hold down, can guarantee that interface card is solidly plugged on the busbar channel really,, also not have the situation that gets loose when product is transported or user when plugging.

Embodiment

Below in conjunction with drawings and Examples the utility model is further described.

Fig. 2,3 are depicted as embodiment of the present utility model, wherein interface card 1, be that its catch 11 of nationality is arranged on the draw-in groove 2 of computer casing, and utilize press fastening device 3 with the interface card fixed bit, press fastening device 3 is that correspondence is located at the distolateral of draw-in groove 2, it comprises by a base 31 and some slide blocks 32 and combines, and row are provided with some chutes 311 in the top of base 31, the front portion of base 31 has a header board 312 and tenon 313, the bottom of header board 312 forms an elasticity fixture block 314, this elasticity fixture block 314 can pass through the frame hole 315 of header board 312 lower ends, rear to base 31 extends, utilizing the default convex clip 316 of fixture block 314 end faces, 317, the clip when doing slide block 32 displacements is spacing.Slide block 32 is the top that correspondence is located at chute 311, can appropriate slippage, and its upper end has extended a cantilever 321, and inside then provides a derby 322 correspondences to be forced into, and fixed one, makes the projection 323 of derby 322 root edges stretch out slide block 322 distolateral predetermined lengths.
