Problems solved by technology

If the positioning holes are still designed according to the above-mentioned methods, after the positioning holes pass through the PCB board, the inner layers of the PCB board will also be opened, so that the parts of each layer that have been opened up cannot be used, which will affect the space of the PCB board. Occupation is increasingly unacceptable

Embodiment Construction

[0031] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below through specific embodiments and with reference to the accompanying drawings.

[0032] In order to solve the technical problem that the fixed structure on the PCB board 10 in the prior art occupies too much space on the PCB board 10, an embodiment of the present invention provides a fixed structure on the PCB, such as Figure 4 As shown, it includes: screws 70, a PCB board 10 and a structural member 20 fixed on the PCB board 10;

[0033] The PCB board 10 and the structural member 20 are respectively provided with a first fixing hole 60 and a second fixing hole 50 for fixing with screws 70 . Wherein, the first fixing hole 60 is a through hole, and the second fixing hole 50 is a blind hole; or the first fixing hole 60 is a blind hole, and the second fixing hole 50 is a through hole. In this embodiment, preferably, the fi...

Abstract

The invention discloses a fixing structure of a PCB. The fixing structure comprises a screw, the PCB and a structural component fixed to the PCB. The PCB and the structural component are provided with a first fixing hole and a second fixing hole respectively, and the screw is embedded in the first fixing hole and the second fixing hole. At least one face of the PCB is provided with a protruding bonding pad, and protrusions are formed on the protruding bonding pad. The face, attached to the PCB, of the structural component is provided with grooves matched with the protrusions. When the fixing structure is used, the first fixing hole is aligned with the second fixing hole, the protrusions of the PCB are clamped in the grooves of the structural component, and the screw penetrates through the first fixing hole and the second fixing hole to be fixed. According to the fixing structure, the protrusions are arranged on the PCB, the structural component is provided with the grooves, positioning is convenient, all layers of the PCB do not need to be drilled, and the space of the PCB is saved. The invention further discloses the PCB with the fixing structure.

Description

technical field [0001] The invention relates to the technical field of PCB, in particular to a fixing structure on the PCB and a PCB board. Background technique [0002] In the process of electronic product design, PCB is often used in conjunction with structural parts. At this time, it is necessary to design mounting holes on the PCB, and fix the structural parts on the PCB by screws. [0003] In the prior art, a way of fixing structural parts can be found in figure 1 , that is, only one screw 3 is used to fix the structural member 2 on the PCB board 1 . In this way, the structural part 2 will rotate around the screw 3 when it is fixed, and the position is not fixed, which will affect the normal use of the structural part 2 and may further affect other devices on the PCB 1 . [0004] Another improved way of fixing structural members see figure 2 . In order to ensure that the position of the structural member relative to the PCB board 1a is fixed, the structural member...
