Embodiment 1

[0040] Please also refer to Figure 1 to Figure 3 , this embodiment provides a fixed structure 100 applied to the PCBA board 30, the structure of the fixed structure 100 is simple, easy to assemble, can reduce the stress on components during assembly, avoid stress concentration, and can also avoid tin cracks phenomenon, and has good applicability.

[0041] The fixing structure 100 at least includes: a structural body 10 and at least one pair of elastic members 20, a notch 11 is formed on the structural body 10, and the notch 11 is arranged in a U-shape, and the opposite sides of the notch 11 are correspondingly provided with installation grooves 12 , the PCBA board 30 can be vertically inserted and fixed on the structural body 10 along the installation groove 12 ; Wherein, the side of the elastic member 20 facing the side of the installation groove 12 is formed with a barb portion 21, the barb portion 21 can be embedded and fixed at the side wall position of the installation ...

Embodiment 2

[0047] The difference with the first embodiment above is that:

[0048] Please also refer to Figure 4 to Figure 6 In order to better fix the PCBA board 30 vertically inserted into the installation groove 12 based on the pressing part 221, a limited opening 31 is formed on the layer of the PCBA board 30 facing the installation groove 12, and each pressing part 221 can penetrate into the limiting opening 31 , so that each pressing portion 221 can be locked against the limiting opening 31 , thereby achieving the effect of preventing the PCBA board 30 from falling out of the mounting groove 12 .

Embodiment 3

[0050] The difference with the above-mentioned second embodiment is:

[0051] Please also refer to Figure 7 to Figure 10 The elastic member 20 provided in this embodiment is formed with a guide groove 22, and the end portions of the two side walls of the guide groove 22 facing the bottom surface of the notch 11 are formed with pressing portions 221, and each pressing portion 221 is at least partially movably overlapped. It can be understood that when the PCBA board 30 is not inserted into the guide groove 22, at least part of the two pressing parts 221 overlap each other, as Figure 9 As shown; when the PCBA board 30 is gradually inserted along the guide groove 22, the two pressing parts 221 can be separated from each other under the promotion of the PCBA board 30, until the two pressing parts 221 and the limit opening on the PCBA board 30 After that, the two pressing parts 221 penetrate into the limiting opening 31 and the two pressing parts 221 return to a partially overla...

Abstract

The invention relates to a fixing structure of a PCBA board. The fixing structure comprises a structure body and a pair of elastic parts, a fixing part and a fixing part, wherein a notch is formed in the structure body, and mounting grooves are correspondingly formed in two opposite side surfaces of the notch; the elastic parts are arranged in the mounting grooves in a one-to-one correspondence manner; and one side, facing the side wall of the corresponding mounting groove, of each elastic piece is provided with a barb part, the barb part can be embedded and fixed on the side wall of the corresponding mounting groove, and the elastic pieces can abut against and be fixed with the edges of the PCBA board. According to the fixing structure, the mounting grooves allowing the PCBA board to be vertically inserted are formed in the two opposite side faces of the notch of the structure body, the barb parts of the elastic pieces are embedded and fixed to the side walls of the mounting grooves, meanwhile, the elastic pieces abut against and are fixed to the edges of the PCBA board, in this way, the PCBA board can be rapidly and vertically fixed, the fixation is firm, the stress concentration of components can be effectively reduced, a tin crack phenomenon of the components can be avoided, and the installation occupied space is small.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a fixing structure of a PCBA board. Background technique [0002] PCBA is the abbreviation of Printed Cricuit Board+Assembly in English, that is, the PCB empty board passes through the SMT upper part, and the whole process of DIP plug-in, referred to as PCBA. [0003] The traditional PCBA board is fixed by screws. After assembly, it is easy to cause stress concentration on the components on the PCBA board, and it is also easy to cause tin cracks in the solder of the components near the screw holes, which will affect the electrical function. Contents of the invention [0004] The object of the present invention is to provide a fixing structure applied to a PCBA board. The fixing structure has a simple structure, is easy to install, can reduce stress concentration on components, and can also avoid tin cracking of components. [0005] To achieve the above object, the...
