Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, specifically to a waterproof and pressure-resistant circuit board. Background Technology

[0002] Circuit boards are the core carriers for realizing the electrical connection of components in electronic devices. They are an indispensable part of modern electronic devices. They fix electronic components on an insulating substrate through a process of patterning conductive copper foil and complete the transmission of current and signals.

[0003] Existing patent application number: 202420584791.6 A circuit board with high-efficiency heat dissipation includes a circuit board body, two heat sinks are symmetrically fixedly connected to the side wall of the upper side of the circuit board body, a mounting plate is fixedly connected to the circuit board body, and a cooling fan is fixedly connected to the mounting plate.

[0004] The aforementioned patent describes a functional structure of a circuit board. In practical applications, due to the relatively thin substrate of the circuit board, its pressure resistance is relatively poor, and it is easy to break under pressure. In addition, the surface of the circuit board lacks waterproof measures, resulting in relatively weak overall protection of the circuit board, which is more susceptible to damage from external forces. Therefore, we propose a combined circuit board insert rack to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a waterproof and pressure-resistant circuit board, comprising a circuit board and a surface protection mechanism, wherein the surface protection mechanism is provided at the edge of the circuit board, and the surface protection mechanism includes a pressure-resistant frame, mounting pieces, mounting holes and a waterproof mechanism, wherein the pressure-resistant frame is provided with a cover at the top edge of the circuit board, mounting pieces are symmetrically provided on the left and right sides inside the pressure-resistant frame, mounting holes are symmetrically provided on the left and right sides of the surface of the circuit board, the mounting pieces are locked and fixed to the inside of the mounting holes with screws, and a waterproof mechanism is provided at the top of the pressure-resistant frame.

[0007] Preferably, there are 2 or 4 mounting holes, and the number of mounting pieces is the same as the number of mounting holes.

[0008] Preferably, the pressure-resistant frame is made entirely of polyvinyl chloride plastic.

[0009] Preferably, the waterproof mechanism includes a slide rail, a limiting block, a cover, and a sliding sleeve. The left and right sides of the pressure-resistant frame are symmetrically equipped with slide rails, and the rear end of the slide rail is integrally provided with a limiting block. The top of the pressure-resistant frame is covered with a cover, and the bottom left and right sides of the cover are symmetrically equipped with sliding sleeves. The sliding sleeves are damped and slidably fitted on the surface of the slide rail, so that the cover and the pressure-resistant frame are slidably connected.

[0010] Preferably, the cover is made entirely of aluminum alloy.

[0011] Preferably, a row of heat dissipation fins is provided on the top surface of the cover.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model provides a surface protection mechanism along the edge of the circuit board. The pressure-resistant frame is then placed over the edge of the circuit board from top to bottom, and screws are used to lock the mounting plate and mounting hole together. This completes the installation connection between the pressure-resistant frame and the circuit board. The pressure-resistant frame enhances the structural strength of the circuit board, strengthens its resistance to deformation, and makes it less prone to bending under pressure.

[0014] This utility model features a waterproof mechanism at the top of the pressure-resistant frame.

[0021] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0022] Please see Figure 1 This utility model provides a waterproof and pressure-resistant circuit board, including a circuit board 1 and a surface protection mechanism 2, wherein the surface protection mechanism 2 is provided on the edge of the circuit board 1.

[0023] Please see Figure 2-3 This utility model provides a waterproof and pressure-resistant circuit board. The surface protection mechanism 2 includes a pressure-resistant frame 21, mounting pieces 22, mounting holes 23, and a waterproof mechanism 24. The pressure-resistant frame 21 is snapped onto the top edge of the circuit board 1. Mounting pieces 22 are symmetrically arranged on the left and right sides inside the pressure-resistant frame 21. Mounting holes 23 are symmetrically arranged on the left and right sides of the surface of the circuit board 1. The mounting pieces 22 are locked and fixed to the inside of the mounting holes 23 with screws, thereby realizing the installation connection between the pressure-resistant frame 21 and the circuit board 1. The pressure-resistant frame 21 improves the structural strength of the circuit board 1, enhances its resistance to deformation, and makes it less prone to bending under pressure. The top of the pressure-resistant frame 21 is provided with a waterproof mechanism 24.

[0024] To further explain, there are 2 or 4 mounting holes, and the number of mounting pieces 22 is the same as the number of mounting holes 23.

[0025] To further explain, the pressure-resistant frame 21 is made entirely of polyvinyl chloride plastic. Polyvinyl chloride plastic has good strength, wear resistance and electrical insulation, which enables the pressure-resistant frame 21 to provide good support strength for the circuit board 1.

[0026] Please see Figure 4-5 This utility model provides a waterproof and pressure-resistant circuit board. The waterproof mechanism 24 includes a slide rail 241, a limiting block 242, a cover shell 243, and a sliding sleeve 244. The slide rail 241 is symmetrically installed on the left and right sides of the pressure-resistant frame 21. The limiting block 242 is integrally provided at the rear end of the slide rail 241. The cover shell 243 is provided on the top of the pressure-resistant frame 21. The sliding sleeve 244 is symmetrically installed on the left and right sides of the bottom of the cover shell 243. The sliding sleeve 244 is damped and slidably sleeved on the surface of the slide rail 241, so that the cover shell 243 and the pressure-resistant frame 21 are slidably connected.

[0027] To further explain, the cover 243 is made of aluminum alloy. Aluminum alloy has the characteristics of high thermal conductivity and low density, which makes the cover 243 lighter overall, and the heat inside the cover 243 can be more easily conducted and dissipated to the outside.

[0028] To further explain, a row of heat dissipation fins 245 is provided on the top surface of the cover 243. With the help of the heat dissipation fins 245, the cover 243 can dissipate the heat inside to the outside more quickly, thus better meeting the heat dissipation requirements.

[0029] The working principle is as follows:

[0030] First, by setting a surface protection mechanism 2 at the edge of the circuit board 1, the pressure-resistant frame 21 is first placed on the edge of the circuit board 1 from top to bottom, and then the mounting plate 22 is locked and fixed to the mounting hole 23 with screws, thereby completing the installation connection between the pressure-resistant frame 21 and the circuit board 1. The pressure-resistant frame 21 enhances the structural strength of the circuit board 1, strengthens its resistance to deformation, and makes it less prone to bending under pressure.

[0031] Secondly, by setting a waterproof mechanism 24 on the top of the pressure-resistant frame 21, when installing the cover 243, the sliding sleeve 244 is first slidably mounted on the surface of the slide rail 241 from front to back until the sliding sleeve 244 is blocked by the limiting block 242, thereby sliding the cover 243 onto the top of the circuit board 1. The cover 243 can provide surface protection for the circuit board 1, making the circuit board 1 less susceptible to damage from external forces.

[0032] Third, by setting heat dissipation fins 245 on the top surface of the cover 243, the cover 243 can dissipate the heat inside to the outside more quickly with the help of the heat dissipation fins 245, so as to better meet the heat dissipation requirements.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
