Embodiment Construction

[0012] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0013] figure 1 It is a schematic cross-sectional structure diagram of a PCI card fixing device in a specific embodiment of the present invention. Such as figure 1 As shown, a motherboard 3 is installed on the chassis side 1, and one end of a plurality of PCI boards 4 is fixed on the motherboard, but these PCI boards are inserted on the motherboard, so in the process of handling and transportation, due to PCI The self-weight of the board will cause the PCI board to be insecure or loose during shaking.

[0014] Therefore, in this specific embodiment, a pressing plate 5 is added. This pressing plate is L-shaped, and one end is fixed on the rear part 2 of the case, and the other end is fixed on the side part 1 of the case. Elastic cushions are set between the pressing plate and the PCI board. 6. In ...

Abstract

The invention discloses a design for solving the problem of loosening of a PCI long board clamp. A pressing plate is arranged at first, the two ends of the pressing plate are fixed on a machine box, one end of the PCI board clamp is fixed on a main board, and the middle of the pressing plate is used for limiting the other end of the PCI board clamp. By means of the technical scheme, the phenomena that the PCI board clamp is not in firm contact and looses when an instrument is carried and transported can be thoroughly avoided.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a design for solving the loosening of PCI long boards. Background technique [0002] At present, in the design and production of various instruments, PCI boards have been widely used. However, most of these boards are end-fixed, and their impact resistance and vibration resistance are poor. Especially when the board is long and heavy, it will cause looseness and poor connection during moving and transportation. The phenomenon is more serious. Contents of the invention [0003] The object of the present invention is to propose a method and device for fixing a PCI board, which can completely solve the phenomenon of poor contact and loosening of the PCI board caused by the instrument during moving and transportation. [0004] For reaching this purpose, the present invention adopts following technical scheme: [0005] A method for fixing a PCI board, comprising sett...
