Abstract

The present invention discloses the tight device of CF kayser that a kind of CF of preventing card is deviate from from CF card connector. This locking device becomes a parts (1) according to the contour structures ingehious design of CF card connector, it is held on the CF card connector having installed CF card, CF fastened in a suitable space, CF card is produced forward, be subject to power with downward backward so that it is can not all around move. Strong motion, impact environment prevent its contact pin following CF card connector from loosening so that coming off, strengthens the reliability of electrical connection between CF card and CF card connector. This locking device is applicable to most CF card connector, has structure simple, with low cost, part standard, feature easy for installation.

Description

A kind of tight device of CF kayser

Technical field

The invention belongs to technical field of electronic equipment, in particular to compact flash (CompactFlash is called for short CF) the tight device of kayser.

Background technology

CF card connector on current market does not all have locking latches, at strong motion, impacts in environment, it is easy to deviate from from junctor, causes the electrical connection of CF card unreliable. Ensure its reliability, it is common practice to for different product designs special add fixing structure, make complex structure, with high costs, stdn cannot be accomplished.

Summary of the invention

The present invention is directed to the defect of CF card connector in described prior art, it is proposed to the tight device of CF kayser that a kind of CF of preventing card is deviate from from CF card socket, ensure in strong motion, the reliability impacting CF card application in environment.

The tight device of CF kayser of the present invention is the tight device of CF kayser that a kind of CF of preventing card is deviate from from CF card connector. This locking device becomes parts according to the contour structures ingehious design of CF card connector, by the little hook that front end of the top surface left and right edges is inside, before, the vertical bending of left and right side, end face can be placed on the small rectangle projection in left and right edges, little copper post in the middle part of the bending of rear, and rear bending and the inside little hook of bottom left and right edges, fasten CF in suitable space together with CF card seat, CF card is produced forward, is subject to power with downward backward so that it is can not all around move. Ensure CF card and the reliability of CF card connector electrical connection.

This locking device is a standardized unit according to CF card connector form construction design, it is applicable to most CF card connectors, at strong motion, impact the reliability ensureing CF card and the electrical connection of CF card connector in environment, there is structure simple, with low cost, part standard, the feature installing simplicity.

Embodiment

Below in conjunction with accompanying drawing, the invention will be further described:

Fig. 1 is the locking device vertical view of the present invention.As shown in the figure, the front bending (7) of this locking device, left and right side's bending (8,9) encases three of CF card connector from outside; Rear bending (16) and the inside little hook (14,15) of rear end, bottom surface left and right edges two encase the CF card afterbody of insertion. The inside little hook (2,3) of front end of the top surface left and right edges two can directly insert the miniature oblong shaped orifices of CF card connector stitch face the right and left. There are two small rectangle projections (12,13) to be pressed in CF card left and right edges in the middle part of end face left and right edges, utilize elasticity upwards to be mentioned by the afterbody of CF card and eliminate gap to prevent CF is stuck in basal groove rocks. There is a circular aperture that copper post is installed in the middle part of the bending of rear, can support CF card afterbody after CF card inserts CF card connector. End face front portion utilizes the tab construction of small column both sides again to lock from end face while having two small columns that two special-shaped apertures (4,5) are avoided on CF card socket. End face four limit has three longer slotted holes (10,11,18) and a shorter slotted hole (6). Elongated hole is the elasticity increasing the locking above-mentioned multiple bending part of device. A shorter slotted hole is auxiliary dismounting fabrication hole, when free-hand dismounting inconvenience, this hole screwdriver can be utilized to stir and dismantle.

Fig. 5 is the three-dimensional scheme of installation being arranged on the CF junctor being inserted with CF card by tight for CF kayser device. the installation mode of this locking device is: first CF card is inserted CF card socket, the upper little copper capital installed of the small sircle hole (17) in bending after device (16) will be locked again at CF card afterbody, the inside little hook (14 of rear end, bottom surface left and right edges two, 15) CF card afterbody is encased, utilize the elasticity of bending (16), the firmly little hook (14 of horizontal sliding, 15) position, by inside for the front end of the top surface left and right edges two of locking latches little hook (2, 3) two small rectangle holes of CF card socket are inserted, and lock the bending (7 of device, 8, 9) with CF card socket before, three, left and right fits tightly naturally, thus CF is fastened in a suitable space, CF card is produced forward, it is subject to power backward with downward, it is made to move all around. ensure CF card and the reliability of CF card connector electrical connection.
