Description

Interface card positioning device

This invention relates to an interface card positioning device, particularly a device that allows a second plate to be fixed in a fixed space or unlocked in an unlocking space by rotating a fixing portion, thereby allowing the plates to be firmly fixed and unlocked while being electrically conductive, thereby eliminating the cost of assembling springs or other elastic elements to position the plate by elastic pressure.

In today's booming electronics industry, the performance of computers or servers is improving day by day. In order to cope with various environments, the hardware inside the computer needs to be strengthened in all aspects of assembly to match the subsequent combination and use of various peripheral devices.

Among them, various interface cards assembled on the motherboard in the computer are one of the important hardware to enhance the computer performance. However, the interface is assembled on the suspended end of the motherboard or circuit board, and is mostly locked in place with screws. However, the locking structure of the screws is not conducive to the removal of the interface card, which makes the maintenance and inspection work very laborious and time-consuming. In addition, there is a risk that the screws will fall on the circuit boards after being removed, which may cause short circuits in the circuit boards.

Therefore, a positioning device that fixes the interface card by a simple snap-fit has been developed. However, most positioning devices fix the interface card by the elastic holding force of a spring or other elastic element, which increases the manufacturing cost of the positioning device. The spring or other elastic element also has the risk of popping out, and is not conducive to the assembly of a miniaturized positioning device. This is the key point that the industry is eager to study and improve.

Therefore, in view of the above problems and deficiencies, the creator collected relevant information, evaluated and considered various aspects, and used the years of experience accumulated in this industry. After continuous trials and modifications, he finally designed this new patented device with an interface card positioning device.
