Description

Technical Field

[0001] This utility model relates to the field of printed circuit board assembly technology, and in particular to a printed circuit board mounting structure. Background Technology

[0002] Printed Circuit Boards (PCBs) are core components of electronic devices. For example, in the internal structure of various electronic devices, I / O boards are key components that enable data interaction and signal transmission between the device and the outside world. Therefore, a stable and reliable method for fixing I / O boards is required.

[0003] Currently, the traditional method of fixing the I / O board typically involves directly mounting it in a specific location inside the device using connectors (such as screws). However, this method requires the disassembly or relocation of other internal components to create sufficient space for the installation. In situations with limited internal space and complex structures, this significantly increases the difficulty of installation, adding considerable complexity and time. Furthermore, the confined internal space obstructs the installer's view, making operation difficult. Additionally, screws are prone to falling out during installation, causing instability and further complicating the process. Therefore, improvements are urgently needed. Utility Model Content

[0026] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that many specific details are set forth in the following description to provide a full understanding of this utility model; however, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0027] like Figure 1 and Figure 2 As shown, this embodiment provides a printed circuit board mounting structure, including: a sliding bracket 1, a mounting bracket 2, and a housing 3.

[0028] The mounting bracket 2 is fixed on the housing 3; the sliding bracket 1 is sleeved on the mounting bracket 2 and can slide left and right along the length of the mounting bracket 2.

[0029] like Figure 2 As shown, the sliding bracket 1 is located between the mounting bracket 2 and the housing 3. In this embodiment, the direction from the mounting bracket 2 to the housing 3 is recorded as from front to back, that is, the mounting bracket 2 is located in front of the sliding bracket 1 and the housing 3 is located behind the sliding bracket 1.

[0030] like Figure 3As shown, the sliding bracket 1 includes a support plate 10, a handle 11, slide rails 12, and multiple slots 13. There are two slide rails 12. The handle 11 and the two slide rails 12 are perpendicular to the support plate 10 and located on the same side of the support plate 10. The two slide rails 12 are symmetrically arranged at both ends of the support plate 10 along its length, and the handle 11 is perpendicular to one end of the support plate 10 along its width (denoted as the left end of the sliding bracket 1). As an example, the two slide rails 12 can be formed by folding the edges of both ends of the support plate 10.

[0031] The support plate 10 is provided with a fixing hole 14, which is close to the handle 11.

[0032] Each slide rail 12 is provided with multiple hooks 15. Preferably, the hooks 15 have a hook-shaped cantilever structure. Here, the number of hooks 15 and their positions on the slide rail 12 can be set according to the structure of the printed circuit board. As an example, each slide rail 12 is provided with three hooks 15 facing the same direction, and the hooks 15 on the two slide rails 12 are symmetrically arranged. In this embodiment, all of the hooks 15 open to the left.

[0033] In this embodiment, the groove 13 is a through hole that transitions vertically from the slide rail 12 to the support plate 10. The shape and size of the multiple grooves can be set according to actual needs, and the multiple grooves 13 are symmetrically arranged along the length direction of the sliding bracket 1.

[0034] Mounting bracket 2 includes: a connecting plate 20, a limiting plate 21, a mounting part, and multiple latches 22.

[0035] As an example, the mounting portions are provided at both ends of the connecting plate 20 along the width direction of the connecting plate 20. It can be understood that the shape of the mounting portions can be designed according to actual needs. For example, the mounting portion located at the left end of the connecting plate 20 is two symmetrical mounting ears 23, and the mounting portion located at the right end of the connecting plate 20 is a mounting piece 24.

[0036] Preferably, a notch is provided between the two mounting ears 23, the position of which corresponds to the position of the handle 11 on the sliding bracket 1. When the handle 11 slides left or right, the notch avoids the handle 11.

[0037] Preferably, the number of limiting plates 21 is two.

[0038] Here, both limiting plates 21 are perpendicular to the connecting plate 20 and located on the same side of the connecting plate 20. The two limiting plates 21 are symmetrically arranged at both ends of the connecting plate 20 along its length. As an example, the two limiting plates 21 can be formed by folding the ends of the connecting plate 20.

[0039] Each limiting plate 21 is provided with multiple limiting parts, and the leftmost limiting part is designated as the stopping part 25. Preferably, the position of each limiting part corresponds to the position of the hook 15. When the sliding bracket 1 slides left and right, a limiting part and the corresponding hook cooperate with each other to limit and release the printed circuit board.

[0040] The stop portion 25 has two continuously bent retaining platforms, referred to as the first retaining platform 26 and the second retaining platform 27, respectively. The first retaining platform 26 is used for leftward limiting of the printed circuit board, and the second retaining platform 27 is used for rearward limiting of the printed circuit board. Other limiting portions (i.e., limiting portions other than the stop portion 25) may be bosses 28, used for rearward limiting of the printed circuit board.

[0041] The latch 22 is provided on the limiting plate 21. Preferably, the two limiting plates are symmetrically provided with the same number of latches. It can be understood that the shape and size of the multiple latches 22 can be set according to actual needs.

[0042] Preferably, the number of grooves 13, hooks 15, tongues 22, and limiting parts are all the same. In this embodiment, the number of grooves 13, hooks 15, tongues 22, and limiting parts are all six; wherein, each limiting plate 21 has three limiting parts (two limiting plates 21 have six limiting parts), the leftmost limiting part is a stop part, and the other two limiting parts are bosses.

[0043] In this embodiment, the length of each groove 13 is greater than the length of the latch 22. When the sliding bracket 1 is fitted onto the mounting bracket 2, each latch 22 is inserted into the corresponding groove 13.

[0044] When the mounting bracket 2 is fixed to the housing 3, the sliding bracket 1 located between the mounting bracket 2 and the housing 3 achieves front-to-back direction limitation. Two slide rails 12 are fitted onto two limiting plates 21, achieving vertical limitation of the slide rails 12 while allowing horizontal sliding. Each latch 22 is inserted into the corresponding slot 13, achieving horizontal sliding limitation of the slide rail 12. It can be understood that the two limiting plates 21 act as slideways, and through cooperation with the two slide rails 12, allow the sliding bracket 1 to be mounted on the mounting bracket 2, enabling the sliding bracket 1 to slide horizontally on the mounting bracket 2. Specifically, one slide rail is located above one limiting plate, and the other slide rail is located below the other limiting plate, forming an installation structure where the two limiting plates 21 are located between the two slide rails 12, allowing the two slide rails 12 to slide horizontally on the two limiting plates 21, but with vertical limitation. During the sliding of slide rail 12 to the left, the latch 22 is stopped when it contacts the rightmost side of the groove 13; during the sliding of slide rail 12 to the right, the latch 22 is stopped when it contacts the leftmost side of the groove 13, thereby achieving the left and right sliding limit of slide rail 12.

[0045] The housing 3 is provided with mounting holes 30.

[0046] Preferably, the sliding bracket 1, the mounting bracket 2, and the housing 3 are each provided with a plurality of clearance holes to avoid components on the printed circuit board, thereby enabling the printed circuit board to be mounted on the printed circuit board mounting structure of this embodiment. It can be understood that the shape, size, and number of clearance holes can be set according to the actual size of the components to be avoided.

[0047] As an example, the material of the printed circuit board mounting structure in this embodiment can be hot-dip galvanized steel sheet, stainless steel sheet, etc.

[0048] The following describes in detail the process of installing the IO board 4 into the printed circuit board mounting structure of this embodiment, taking the IO board in a printed circuit board as an example. There are multiple fixing parts 40 for the IO board, symmetrically arranged along the length of the IO board at positions corresponding to the limiting parts; in this embodiment, there are six fixing parts 40, symmetrically arranged along the length of the IO board. Installing one fixing part 40 requires the cooperation of one limiting part, one hook 15, one tongue 22, and one slot 13 for fixation.

[0049] like Figure 4 and Figure 5 As shown, the sliding bracket 1 is sleeved on the mounting bracket 2, and the mounting bracket 2 is fixed to the housing 3 by the mounting ear 23 and the mounting piece 24. For example, screws can be used for fixing. Here, on each limiting plate 21, the end face 280 of the boss 28 is on the same plane as the second abutment surface 270 of the second locking plate 27.

[0050] like Figure 6 and Figure 7 As shown, the fixing part 40 of the IO plate 4 is placed corresponding to the limiting part on the mounting bracket 2. Specifically, the two upper and lower fixing parts 40 located on the leftmost side of the IO plate 4 contact the right side of the two upper and lower first locking platforms 26 (denoted as the first abutting surface 260) and the front side of the two upper and lower second locking platforms 27 (denoted as the second abutting surface 270), and the other fixing parts contact the end face 280 of the corresponding boss. The two first locking platforms 26 limit the IO plate in the vertical direction (i.e., the IO plate cannot move up and down), the first abutting surface 260 of the two first locking platforms 26 limits the IO plate to the left (i.e., the IO plate cannot move to the left), and the second abutting surface 270 of the two second locking platforms 27 and the end face 280 of all the bosses limit the IO plate to the rear (i.e., the IO plate cannot move to the rear).

[0051] Will Figure 6 Rotate the view to obtain Figure 8 This is to show the IO board mounting structure of this embodiment more clearly from different perspectives.

[0052] like Figure 8As shown, each fixing part of the IO plate is placed in a position corresponding to the limiting part. Pull the handle 11 on the sliding bracket 1 to the left, so that each hook 15 hooks onto the fixing part 40 of the IO plate. Pull until the sliding bracket 1 is limited and cannot slide to the left (that is, the groove 13 is limited by the latch 22). At this time, the hooks 15 limit the IO plate 4 to the forward and right (that is, the IO plate cannot move forward or to the right); fix the sliding bracket 1 to the housing 3, forming as shown. Figure 9 The image shows the completed installation status of the I / O board.

[0053] When the sliding bracket 1 is limited and cannot slide to the left, the fixing hole 14 on the sliding bracket 1 is aligned with the mounting hole 30 on the housing 3, and the sliding bracket 1 can be fixed to the housing 3 with screws.

[0054] Preferably, the height of the fixing part 40 of the IO plate 4 is greater than or equal to the sum of the thickness of the stop part 25 and the thickness of the hook 15, so that the stop part 25 and the hook 15 cooperate with each other to hook and limit the fixing part 40.

[0055] When disassembling the IO board 4, remove the screws used to fix the sliding bracket 1 and the housing 3, pull the handle 11 on the sliding bracket 1 to the right until the sliding bracket 1 is limited and cannot slide to the right. At this time, all the hooks 15 will slide outside the fixing part 40 of the IO board 4 (that is, the hooks 15 do not hook the fixing part 40). Move the IO board 4 forward to complete the disassembly.

[0056] In another embodiment, the IO board mounting structure of this embodiment is actually applied to an electronic device. The board body of the electronic device used for mounting can be used as the housing of the IO board mounting structure of this embodiment. For example, the sliding bracket 1 and the mounting bracket 2 are fixed to the inner wall of the housing of the electronic device.

[0057] The printed circuit board mounting structure provided by this utility model allows the sliding bracket to slide left and right on the mounting bracket. When installing the printed circuit board, the printed circuit board is placed on the mounting bracket, and the printed circuit board is fixed by pulling the sliding bracket, which effectively simplifies the fixing process and significantly reduces the installation difficulty.

[0058] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
