[0002]The current common method of fixing computer motherboards is to use several screws to fix the screw locks on a board inside the casing, and this assembly method Whether the main board is assembled on the seat board or removed from the seat board, the screws need to be tightened or loosened. In particular, more than six screws are usually used to fix the main board, so not only the assembly It is troublesome, and a lot of time will be wasted in the process of tightening or loosening the screws, which will affect the work efficiency

Embodiment Construction

[0031] see figure 1 , figure 1 Disclose the circuit board assembly structure and its waveguide device described in the present invention, its structure includes:

[0032] A carrier 1 is a conductive material; in this embodiment, the carrier 1 includes a computer case 10 and a seat board 11, the seat board 11 is assembled on the computer case 10, and the computer case 10 has a shell The wall 100 is perpendicular to the seat plate 11;

[0033] Several waveguide devices 2 are arranged on the carrier 1 and are used to support the circuit board 5 at an appropriate height and prevent the circuit board 5 from moving laterally, and can be electrically connected to the circuit board 5 and the carrier 1 for The electromagnetic wave leaked from the circuit board 5 is guided to the housing wall 100 to reduce electromagnetic interference (EMI). In this embodiment, there are eight sets of waveguide devices 2, all of which are arranged on the seat board 11, and the circuit board 5 is a ma...

Abstract

A circuit board assembly structure and wave-guide devices thereof are used for assembling a circuit board on a shell wall. Each wave-guide device comprises a fixed column and a conductive spacer. The fixed column is combined on the shell wall and can be used for embedding the fixing holes on a circuit board and supporting the circuit board in an appropriate height. The conductive spacer is equipped with a substrate and at least two spring plates; wherein, the substrate can axially move along the fixed column and clings to the conductive layer on the bottom surface of the circuit board; the two spring plates extends from the edge of the substrate to be contacted with the shell wall. A plurality of fixed fasteners are arranged on the shell wall and used for embedding the corresponding edge of the circuit board so as to prevent the fixing holes of the circuit board from detaching the fixed column to the outward axial direction.

Description

【Technical field】 [0001] The invention relates to the technical field of circuit board assembly structures, in particular to a circuit board assembly structure and a wave guide device for assembling and disassembling circuit boards and reducing electromagnetic interference. 【Background technique】 [0002] At present, the common way of fixing computer motherboards is to use several screws to fix the screw locks on a board inside the casing, and this assembly method is whether to assemble the motherboard on the seat board or disassemble it. The seat board needs to be tightened or loosened by the screws, especially generally more than six screws are usually used to fix the main board, so not only is it troublesome to assemble, but also in the process of tightening or loosening the screws A lot of time will be wasted and work efficiency will be affected. 【Content of invention】 [0003] The main purpose of the present invention is to overcome the deficiencies of the prior art,...
