Problems solved by technology

like figure 1 As shown, the traditional technology generally uses metal screws to fix the circuit board with multiple perforations. Although there are endless power tools for removing and installing screws, from the perspective of overall assembly efficiency, it is still quite time-consuming to repeatedly remove and install screws.
In addition, the model matching and wear and tear of the screws are the cost and safety hazard of using screws to mount the circuit board

Embodiment 1

[0032] Such as Figure 2a Shown is a schematic diagram of the structural details of an embodiment of the attachment structure elastic piece of the present invention. It can be seen from the figure that the circuit board mounting frame used in this mounting structure is an open rectangular columnar frame structure, and two or four shrapnels are arranged in pairs in the relief groove 11 set on the side wall of the frame body. . in:

[0033] One end of the elastic piece 41 connects with the bottom of the relief slot, and is integrally formed on the circuit board mounting frame 1 . It is worth mentioning that in this embodiment, the top of the elastic piece 41 is lower than the top plane of the circuit board mounting frame 1 . Both sides of the top end of the elastic piece 41 extend toward the circuit board coverage area to form a pair of stoppers 411. As an example only, the top edge of the stopper 411 in this specific embodiment is formed to conform to the position of the circ...

Embodiment 2

[0037] Such as Figure 2b Shown is a schematic diagram of the structural details of another embodiment of the attachment structure elastic piece of the present invention. It can be seen from the figure that the circuit board mounting frame used in this mounting structure is an open rectangular columnar frame structure, and two or four shrapnels are arranged in pairs on the peripheral side walls of the frame (not shown). However, it is different from Embodiment 1 in that the mounting position of the circuit board is higher than the top surface of the frame. in:

[0038] The bottom end of the elastic piece 42 is fixedly connected to the circuit board mounting frame 1 , and the part above the bottom end of the elastic plate, especially the part where the stop part is located, stands on the top plane of the circuit board mounting frame. Both sides of the top of the elastic piece 42 extend toward the circuit board coverage area to form a pair of stoppers 421, and the top edge of ...

Embodiment 3

[0041]Such as Figure 5 As shown, it is basically similar to the first embodiment, except that the top of the elastic piece 43 is higher than the top plane of the circuit board mounting frame 1 . At this time, the relief groove 11 of the circuit board mounting frame 1 extends outward along the side wall, and the extended length g satisfies: greater than the outward expansion deflection of the shrapnel when the circuit board is pressed against the bottom of the inclined part (that is, when the circuit board When the board is connected, the maximum bending range of the shrapnel).

[0042] In addition to the above three embodiments, the present invention also has other diverse embodiments, which are all produced based on the circuit board attachment structure of the elastic sheet. For example:

[0043] On the one hand, according to different circuit layouts and differences in the number, size, and shape of circuit boards required by various electronic devices, the circuit board...

Abstract

The invention discloses an assembly structure of a circuit board and an electronic device with an assembly structure, wherein the assembly structure of the circuit is arranged on the periphery of an assembly frame of the circuit board; and the assembly structure is as follows: more than two spring leaves are fixed in the positions which are opposite to the assembly frame of the circuit board, the top ends of the spring leaves extend by facing to a covered region of the circuit so as to form stop parts, tilted parts which can spread the spring leaves outwards along the pressing direction of the circuit board during the assembly are arranged at the top edges of the top parts, and a positioning part for supporting the circuit board for hanging in the air and assembly is arranged in the position where the distance between the lower edges of stop parts is larger than the thickness of the circuit board. The assembly structure can effectively improve the assembly efficiency and the detachment efficiency of the circuit board and significantly reduce the cost consumption of using a large number of screws in the traditional structures by utilizing the elastic characteristic of metal or plastic sheet bodies after implementing the technical scheme.

Description

technical field [0001] The invention relates to a mechanical assembly structure, in particular to a circuit board assembly structure used in the electronic assembly industry. Background technique [0002] With the development of the electronic industry for hundreds of years, electrical equipment is now closely related to the production and life related to human civilization. Whether it is large equipment or small equipment, in addition to the CPU chip with highly integrated functions, the circuit board is still an important part of the electrical equipment to achieve its multi-function. Small electrical products based on a single circuit board formed by the combination of several electronic components, as large as industrial electrical equipment with dozens of multi-circuit boards composed of electronic components with different functions and sizes. It can be said that circuit boards are everywhere. [0003] However, regardless of the degree and size of the application, th...
