Description

Fixing device of board end card

This creation provides a fixing device for a board end card, especially the telescopic rack of the fixing device is an action of telescopic displacement on the fixing rack to adjust the space size of the storage board end card, which can be used for board ends of different sizes and lengths The card is stably combined with the seat body, thereby improving the convenience of use.

According to the press, computer technology is developing rapidly with each passing day, and desktop or notebook computers have been ubiquitous in all corners of the society. The development trend of its computers is also moving towards the direction of strong computing function, fast speed and small size, making the internal computer The connector has also been greatly reduced to meet the current development trend of computers. In addition, in order to cooperate with the continuous improvement and improvement of computer operation functions, the motherboard of its computer must be expanded with memory cards, interface cards or function boards. In order to upgrade the overall application functions, operating efficiency and operating capabilities, however, in order to expand the memory card, interface card or function board on the motherboard, the corresponding connector on the motherboard should also be provided for various types of memory cards, The interface card or function board is electrically plugged in and used as a transmission of electronic signals.

However, at present, the connector of the motherboard is equipped with a locking device. When the expansion memory card, interface card or function board is docked with the connector, it can be fixed by the locking device. However, due to the industrial computer , Onboard computer or other types of computer, vibration will occur during operation, so the lock device is prone to loosen, so that the memory card, interface Cards or function boards are easy to loosen, jump off or come out of the locking device, which can not form a good electrical connection with the connector.

In addition, the general edge card connector (Edge Card Connector) needs to reduce the height to meet the height limit in the manufacturing process, and also needs to meet the minimum use area requirements, so a split-type design scheme is proposed, which is a connector The surface mount technology (SMT) process can be performed first, and then the assembled edge card fixing bracket can be inserted into the connector.

Therefore, some manufacturers first fix the board end card on the fixing frame, and expose the contacts below the board end card to the fixing frame, and then insert the fixing frame into the card edge connector on the circuit board, then the board The end card is fixed to the card edge connector to form electrical conduction, but there are many types of board end cards today, and the size and length of each type are mostly different, so that different sizes of board end cards must be developed to match various sizes of board end cards. The fixing frame causes a lot of manufacturing costs such as mold opening and design, as well as inventory costs.

Therefore, how to solve the above-mentioned lack of inconvenience and inconvenience is the urgent direction for related companies to study and improve.

Therefore, in view of the above problems and deficiencies, the creators collected relevant information, evaluated and considered through multiple parties, and based on years of experience accumulated in this industry, through continuous trial and modification, they began to design such a fixed card. A new type of device was born.

The main purpose of this creation is that the base is provided with a base for positioning on the preset circuit board, and a plug portion for inserting the preset board end card on the surface of the base, and the plug portion Equipped with a plurality of terminals that electrically connect the preset circuit board and the end of the preset board, and then on the two sides of the base There are two arms extending in the same direction, and the two arms are respectively provided with positioning spaces, and the frame body of the fixing frame is formed with a longitudinally penetrating receiving groove, and the left and right outer sides of the frame body are respectively provided for activities The fixed part located in the positioning space is covered with a telescopic frame which can perform telescopic displacement action on the frame body, and the telescopic frame is formed with a matching accommodating groove for different sizes of preset board ends to be inserted into the positioning Sliding space, because the telescopic frame can perform telescopic displacement on the fixed frame to adjust the space for receiving the preset board end card, so that the preset board end cards of different sizes and lengths can be stably combined with the seat body In order to achieve the purpose of improving the convenience of use.

The secondary purpose of this creation is that the second fixing part of the fixing frame is the action of assembling or detaching from the seat body through the shrapnel, thereby eliminating the need to use any tools to stably combine or separate the board end card from the seat body In order to achieve the purpose of improving the speed of disassembly and assembly and the convenience of assembly.
