Description

Technical Field

[0001] The utility model relates to the technical field of circuit boards, and more specifically, to a plug-in type multi-layer PCB circuit board. Background Art

[0002] PCB, also known as printed circuit board, is the cornerstone of electrical connection between electronic components. Although it plays a core role in many products, it is not directly equivalent to the end product. For example, although the motherboard of a personal computer contains a circuit board, it cannot be simply called a circuit board. Therefore, when evaluating the industry, although the two are closely related, there is a clear difference between PCB circuit boards and end products. In the plug-in and fixation process of PCB circuit boards in the prior art, the cooperation between bolts and threaded holes plays a key role. However, if the tightening of the bolts does not follow standard operations, or the anti-corrosion treatment of the bolts is neglected, a series of problems may arise. Bolts are susceptible to oxidation and corrosion if not properly treated, which will not only lead to a decrease in the fastening force of the connection and a loose connection, but may also further affect the stability and normal operation of the circuit board. Utility Model Content

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a plug-in type multi-layer PCB circuit board, which has the advantage of being easy to plug in the PCB circuit board.

[0006] As a preferred technical solution of the utility model, a spring 1 is fixedly installed between the upper fixed block and the lower fixed block, and the spring 1 presents four shapes of the same size.

[0007] As a preferred technical solution of the utility model, the inner length distance of the positioning hole is smaller than the length distance of the limiting block, and the length distance of the limiting block is smaller than the inner length distance of the upper fixing block.

[0008] As a preferred technical solution of the utility model, a fixing plate is fixedly installed at the bottom of the column, and the fixing plates and the columns are grouped in pairs, with a total of four groups inside the PCB circuit board.

[0009] As a preferred technical solution of the utility model, the inner diameter of the hollow cylinder is equal to the outer diameter of the limit block, and the hollow cylinder and the limit block are both made of stainless steel.

[0010] As a preferred technical solution of the utility model, the upper fixing block, the lower fixing block and the spring form a group, and there are eight groups at the top and bottom of the PCB circuit board.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figures 1 to 6 As shown, the utility model provides a plug-in multilayer PCB circuit board, including a PCB circuit board 1, a limiting hole 4 is provided inside the PCB circuit board 1, a column 2 is installed inside the limiting hole 4, a positioning hole 3 is provided inside the column 2, an upper fixing block 7 and a lower fixing block 9 are movably installed on the outer surface of the column 2, and the upper fixing block 7 is below the lower fixing block 9, and a limiting hole 13 is provided inside the upper fixing block 7 and the lower fixing block 9;

[0022] A hollow cylinder 12 is fixedly installed inside the upper fixed block 7 and the lower fixed block 9, a limit block 11 is movably installed inside the positioning hole 3, and the limit block 11 moves inside the hollow cylinder 12, a pull rod 10 is fixedly installed at one end of the limit block 11, and one end of the pull rod 10 completely passes through the interior of the upper fixed block 7, a pull ring 5 is fixed at one end of the pull rod 10, and a spring 8 is fixedly installed between the upper fixed block 7 and the limit block 11.

[0023] Before using the PCB circuit board 1, the staff needs to plug and fix the PCB circuit board 1. First, hold the pull ring 5, pull the pull rod 10 through the pull ring 5 to slide inside the hollow cylinder 12, and then pull the limit block 11 through the pull rod 10 to slide inside the hollow cylinder 12. Then, squeeze the spring 8 through the limit block 11, so that the limit block 11 enters the inside of the hollow cylinder 12. Now the upper fixing block 7 is sleeved on the outer surface of the column 2, and slides downward on the column 2 through the limit hole 13 inside the upper fixing block 7. When it slides down to the specified position, release the pull ring 5. When the spring 28 is pressed against the limit block 11 inside the hollow cylinder 12, the limit block 11 quickly enters the positioning hole 3. The cooperation between the positioning hole 3 and the limit block 11 facilitates the fixing of the upper fixing block 7. The PCB circuit board 1 is slowly sleeved on the outer surface of the column 2, and then passes through the limit hole 4 inside the PCB circuit board 1 and moves to the top of the upper fixing block 7 on the outer surface of the column 2. Now, the same method as the upper fixing block 7 is used to slowly move the lower fixing block 9 to the top of the PCB circuit board 1, thereby completing the plug-in and fixation of the PCB circuit board 1.

[0024] Before using the PCB circuit board 1, it is necessary to plug and fix the PCB circuit board 1. First, hold the pull ring 5, and pull the pull rod 10 and the limit block 11 through the pull ring 5 to slide inside the hollow cylinder 12, and then squeeze the spring 2 8 through the limit block 11 to make the limit block 11 enter the inside of the hollow cylinder 12. Now the upper fixed block 7 is sleeved on the outer surface of the column 2, and slides downward on the column 2 through the limit hole 2 13 inside the upper fixed block 7. When it slides down to the specified position, release the pull ring 5. At this time, the limit block 11 is squeezed inside the hollow cylinder 12 through the spring 2 8, so that the limit block 11 quickly enters the positioning hole 3. The cooperation between the positioning hole 3 and the limit block 11 facilitates the fixing of the upper fixed block 7, and the PCB circuit board 1 is slowly sleeved on the outer surface of the column 2, and then through the limit hole 1 4 inside the PCB circuit board 1, on the outer surface of the column 2 The lower fixing block 9 is moved to the top of the upper fixing block 7. The same method as the upper fixing block 7 is now used to slowly move the lower fixing block 9 to the top of the PCB circuit board 1, thereby completing the plug-in fixation of the PCB circuit board 1. Compared with the traditional PCB circuit board, the PCB circuit board is convenient for fast plug-in fixation through the cooperation between the upper fixing block 7, the limit block 11 and the positioning hole 3, thereby ensuring the stability and reliability of the PCB circuit board and preventing it from moving or vibrating. It is particularly suitable for long-term operation and high-vibration environment. At the same time, the reasonably designed fixing structure and interface simplify the installation and disassembly process and improve production efficiency. In addition, the fixing block also reduces material waste, enhances the overall strength and rigidity, and makes the circuit board more durable. Its design ensures connector alignment, provides convenience for testing and maintenance, shortens maintenance time, and improves the overall performance and maintenance efficiency of the equipment.

[0025] Among them, a spring 1 6 is fixedly installed between the upper fixing block 7 and the lower fixing block 9, and the spring 1 6 presents four shapes of the same size.

[0026] Since the spring 1 6 presents four shapes of the same size between the upper fixing block 7 and the lower fixing block 9, by adding the spring 2 8, the elastic characteristics of the spring 2 8 effectively absorb and buffer external vibrations, thereby protecting the components on the PCB circuit board 1 from damage. At the same time, the deformation recovery ability of the spring ensures the stability of the circuit board during vibration, reduces position offset and structural deformation, and has the advantages of not only enhancing the reliability of the PCB circuit board 1, but also significantly reducing the failure rate and damage rate, thereby effectively extending the service life of the PCB circuit board.

[0027] The inner length of the positioning hole 3 is smaller than the inner length of the limiting block 11 , and the inner length of the limiting block 11 is smaller than the inner length of the upper fixing block 7 .

[0028] Since the internal length of the positioning hole 3 is smaller than the length of the limiting block 11, it is convenient for the limiting block 11 to fix the upper fixed block 7. At the same time, the length of the limiting block 11 is smaller than the internal distance of the upper fixed block 7, which facilitates the limiting block 11 to release the upper fixed block 7 from being restricted on the outer surface of the column 2, thereby improving the applicability of the upper fixed block 7 and ensuring the efficiency of use of the upper fixed block 7.

[0029] A fixing plate 14 is fixedly installed at the bottom of the column 2 , and the fixing plates 14 and the columns 2 are grouped in pairs, with a total of four groups inside the PCB circuit board 1 .

[0030] Since the fixing plates 14 and the columns 2 are arranged in groups of two, there are four groups in total inside the PCB circuit board 1, which facilitates the support of the PCB circuit board 1, ensures the stability and efficiency of the PCB circuit board 1 during use, and extends the service life of the PCB circuit board 1.

[0031] The inner diameter of the hollow cylinder 12 is equal to the outer diameter of the limit block 11 , and both the hollow cylinder 12 and the limit block 11 are made of stainless steel.

[0032] Since the inner diameter of the hollow cylinder 12 is equal to the outer diameter of the limit block 11, it is easy to slide the limit block 11 inside the hollow cylinder 12, so that the position of the limit block 11 will not be offset during the left and right movement. The limit block 11 enters the positioning hole 3 to fix the PCB circuit board 1, which improves the fixing efficiency of the PCB circuit board 1. At the same time, the hollow cylinder 12 and the limit block 11 are made of stainless steel, which improves the use efficiency of the hollow cylinder 12 and the limit block 11.

[0033] Among them, the upper fixing block 7, the lower fixing block 9 and the spring 6 form a group, and there are eight groups at the top and bottom of the PCB circuit board 1.

[0034] Since the upper fixing block 7, the lower fixing block 9 and the spring 6 form a group, there are eight groups at the top and the bottom. When the PCB circuit board 1 is hit, the upper fixing block 7, the lower fixing block 9 and the spring 6 cooperate with each other to effectively absorb and reduce the impact of the external impact on the PCB circuit board, providing all-round protection for the PCB circuit board, thereby ensuring its performance and reliability.

[0035] The working principle and use process of this utility model:

[0036] Before using the PCB circuit board 1, the staff needs to plug and fix the PCB circuit board 1. First, hold the pull ring 5, pull the pull rod 10 through the pull ring 5 to slide inside the hollow cylinder 12, and then pull the limit block 11 through the pull rod 10 to slide inside the hollow cylinder 12. Then, squeeze the spring 8 through the limit block 11, so that the limit block 11 enters the inside of the hollow cylinder 12. Now the upper fixing block 7 is sleeved on the outer surface of the column 2, and slides downward on the column 2 through the limit hole 13 inside the upper fixing block 7. When it slides down to the specified position, release the pull ring 5. At this time, the limit block 11 is squeezed inside the hollow cylinder 12 by the spring 2 8, so that the limit block 11 quickly enters the positioning hole 3. Through the cooperation between the positioning hole 3 and the limit block 11, it is convenient to fix the upper fixing block 7, and the PCB circuit board 1 is slowly put on the outer surface of the column 2, and then passes through the limit hole 1 4 inside the PCB circuit board 1, and moves to the top of the upper fixing block 7 on the outer surface of the column 2. Now, the same method as the upper fixing block 7 is used to slowly move the lower fixing block 9 to the top of the PCB circuit board 1, thereby completing the plug-in and fixation of the PCB circuit board 1.
