Description

M253193 Fourth, the technical description of the creation instructions (1) This creation is about a housing and a fixed module, and in particular, a housing and its interface suitable for screwless assembly of an interface card in the host Card fixing module. Previous technology # f In today's era full of information and multimedia, computers have undoubtedly become one of the necessities in human life and work. It not only makes it easier to store all kinds of information, but also to transmit it faster. The word processing operation is simpler, and it also brings a lot of convenience to people in all aspects of food, clothing, living and entertainment. In fact, "computer" is just a general term for various types of logical computing hosts. They are distinguished according to their purpose and type. Computers can be roughly divided into servers and personal computers (PC for short). In addition, the types and types of personal computers have continued to evolve. From the early desktop PCs, laptop PCs, notebook PCs, and personal digital assistants (PDAs), Until recently, tablet PCs have appeared. The computer can be roughly divided into a display, a host computer and peripheral devices. Among them, the display is what we generally call the screen. Peripherals include mice, keyboards, printers, scanners, and digital cameras. The host part is responsible for the main data operations and storage. The computer host mainly includes a chassis, a motherboard, a memory module, a central processing unit (cp U), an interface card, a power supply, and a data storage device (data storage device). The data storage device includes a floppy disk drive. , Hard drives, optical drives, and recorders, etc., while common interface cards include sound cards,

It is known that when assembling a computer mainframe, most of the time, the interface card is first embedded in various slots on the motherboard, and then one end of the interface card with the connector is fixed to the rear panel of the computer case by screws and tools. The connector is exposed through the opening on the rear panel. In this way, the connector on the interface card can be relatively fixed on the computer case, so that external devices can be firmly connected to the connector, and provide functions such as audio output, image output, data transmission or conversion. However, at present, regardless of the self-assembly (DIY) of a single user or the production line of a computer mainframe, the alignment between the interface card and the computer case is performed manually, and the interface card is carried out by hand tools. Assembly, thus making the overall assembly time longer, relatively increasing the assembly cost of the computer host, and the assembly staff is more likely to break teeth due to poor control of the force when tightening the screws, which will cause the entire locking structure to fail. In addition, during subsequent repairs or replacements, you must also remove the screws between the interface card and the computer case before removing the interface card from the motherboard. Therefore, the conventional way of using screws to fix the position of the interface card not only reduces the assembly speed of the interface card, and therefore consumes the assembly time of the computer host. In the process of repairing the data storage device of the computer host, maintenance personnel may Different, and have to prepare multiple types of screwdrivers to disassemble and assemble screws, which will be extremely time consuming and inconvenient. New content In view of this, the purpose of this creation is to provide a mainframe chassis and its interface card fixing module, which are assembled in combination with screws (sc r e w 1 e s s)
