Example Embodiment

[0031] Example one

[0032] Such as Figure 2a Shown is a detailed structural diagram of an embodiment of the elastic sheet of the attachment structure of the present invention. It can be seen from the figure that the circuit board mounting frame applied by the mounting structure is an open rectangular columnar frame structure, and two or four elastic pieces are arranged in pairs in the recess 11 provided on the side wall of the frame. . among them:

[0033] One end of the elastic piece 41 is connected with the bottom of the relief groove, and is integrally formed on the circuit board attachment 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 attachment frame 1. The top edge of the elastic piece 41 extends toward the circuit board covering area on both sides to form a pair of stoppers 411. As an example, the top edge of the stopper 411 of this embodiment is formed to conform to the mounting ...

Example Embodiment

[0036] Example two

[0037] Such as Figure 2b Shown is a detailed structural diagram of another embodiment of the elastic sheet of the attachment structure of the present invention. It can be seen from the figure that the circuit board mounting frame applied by the mounting structure is an open rectangular columnar frame structure, two or four elastic pieces are arranged in pairs on the peripheral side wall of the frame (not shown), only However, the difference from the first embodiment is that the mounting position of the circuit board is higher than the top surface of the frame. among them:

[0038] The bottom end of the elastic piece 42 is relatively fixed to the circuit board attachment frame 1, and the part above the bottom end of the elastic piece, especially the part where the stopper is located, stands above the top plane of the circuit board attachment frame. The top two sides of the elastic piece 42 extend toward the circuit board covering area to form a pair of stoppe...

Example Embodiment

[0040] Example three

[0041] Such as Figure 5 As shown, it is basically similar to the first embodiment, but the difference is that the top of the elastic sheet 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 meets the requirement: greater than the outer expansion deflection of the elastic sheet when the circuit board is pressed against the bottom end of the inclined portion (that is, when the circuit When the board is assembled, the maximum bending amplitude of the shrapnel).

[0042] In addition to the above three embodiments, the present invention also has other diversified embodiments, and these embodiments are all based on the circuit board mounting structure of the elastic sheet. E.g:

[0043] On the one hand, various electronic devices are based on different circuit layouts and the required number, size, and shape o...

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...
