A fastening device for the interface card.

Background technique

Generally, various types of interface cards are usually installed in the host computer. Since there are many types of interface cards, and different types of interface cards have different lengths, when fixing the interface cards, it is necessary to install different types of locking devices. The cost is high, and the assembly is inconvenient, and it must consume a lot of assembly time, such as the serial peripheral component connection interface card (Peripheral Component Interconnect Express, hereinafter referred to as the PCI-E card). It is inserted horizontally into the slot in the casing, so one of the end corners will be in a suspended state, causing the PCI-E card to be easily loosened due to shaking, resulting in damage to the PCI-E card or slot, or poor electrical contact, etc. .

For patents, for example, China Taiwan Patent Announcement M255435 "Interface Card Fixing Device", it includes a body, on the body is provided with a limit element, the position of the limit element can be moved horizontally and horizontally, and on the body The other side is provided with a linkage element, one end of the linkage element is connected with the limiting element, and the other end is provided with a buckle part, and the linkage element is driven to be vertically displaced by using the horizontal displacement of the limiting element; Install the clamping device on the side plate of the computer host corresponding to the side of the interface card, so that the linkage element corresponds to the interface card, and when the position of the limit element is adjusted laterally, the linkage element will be displaced in the vertical direction , until the buckle part of the linkage element is fastened on the interface card, the interface card will be locked and fixed by the locking device; The locking rod is engaged with the edge of the interface card, and indirectly drives the locking rod. The driving method and structure are complicated. The whole device must occupy a large amount of space, and the locking strength is weak, and adjustment is difficult and time-consuming.

Another example is Taiwan Patent Publication M341876 "Clamping Mechanism for Expansion Card", which includes a support plate and a sliding part. The expansion card is configured in a case and inserted into a slot. The support board is movably fixed on the side wall of the casing, is located above the expansion card, and has at least one sliding rail facing the slot. The sliding part is arranged in the slide rail, and has a buckle part, an operation block and an elastic part combined with the buckle part. In addition, the buckle part has a bottom groove located under the slide rail. In the unfixed state, the slider can move to the end of the expansion card along the slide rail, and adjust the position according to the length of the expansion card so that the end of the expansion card can be embedded in the bottom groove; however, the structure of the slider and the teeth used in this case The engaging method is complicated and the structure is complicated, and the adjustment is difficult and time-consuming.

Another example is Taiwan Patent Publication 440008 "fixing device for interface card", which includes a body, and a plurality of partitions are provided on one side of the seat, the top of the partition is provided with several ratchets at a certain distance, and the bottom is provided with a plurality of partitions. There is a clamping mechanism. In addition, there is a sliding block, which is movably sleeved on the top of the partition with ratchets, and the sliding block is also provided with mutual meshing at the position corresponding to the ratchet on the partition. The ratchets, through the engagement of the plurality of ratchets, the sliding block can be positioned on the partition plate, so that the fixing device can be embedded and buckled on the casing of the computer host, and it corresponds to the circuit board in the computer host One side of the slot. Therefore, when the interface card is to be inserted, the sliding block is first moved upwards, and then the interface card is passed through the clamping mechanism and inserted into the slot of the circuit board. Then, the The interface card can be completely fixed when the sliding block is moved down and stuck against the top of the interface card; however, the base of this case is bulky and must occupy a lot of space, resulting in waste of the position where the interface card is not inserted.

It can be seen from this that, in the currently known interface card locking device technology, there has not yet been a simple and fast operation, simple locking method, simple structure, high and reliable locking strength, light and handy volume, simple installation, and applicable to Fastening device for interface cards of different lengths.
