Description
Technical Field
[0001] This utility model relates to the field of circuit board technology, specifically to a corrosion-resistant and low-loss circuit board. Background Technology
[0002] As the core support and electrical connection carrier of electronic components, the reliability of circuit boards directly determines the performance and lifespan of electronic products. In complex and harsh application environments such as industrial control, automotive electronics, marine equipment, and outdoor communications, circuit boards are exposed to high humidity, salt spray, and chemical corrosion for extended periods, which can easily lead to circuit corrosion, decreased insulation performance, and consequently, increased signal transmission loss and circuit failure.
[0003] Currently used corrosion-resistant and low-loss circuit boards mostly rely on a protective coating for protection on the outside. This method provides poor protection and easily leads to wear and tear on the circuit board, which is detrimental to its subsequent use. In addition, the circuit boards are mostly fixed with screws, which does not allow for easy disassembly and is not conducive to subsequent maintenance, thus reducing the practicality of the circuit board.
[0004] In summary, this utility model solves the problems in the background art by designing a corrosion-resistant and low-loss circuit board. Utility Model Content

A first contact block and a second contact block are respectively disposed on the outer side of the circuit board body. A combination mechanism is provided between the first contact block and the second contact block. An mounting block and a slot are respectively disposed on the outer side of the second contact block. An mounting post and a support post are respectively fixedly installed on the inner wall of the bottom end of the base plate.

[0012] Furthermore, the two ends of the reset spring are fixedly in contact with the bottom surface of the card block and the bottom end of the inner wall of the base plate, respectively, and the card block is in sliding contact with the inner wall of the card slot; Through the above technical solution, the card block can move up and down along the surface of the support column, and the return spring can apply downward preload to the card block, so that the card block can contact the card slot.
[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, by setting a corrosion-resistant and low-loss circuit board, the structural design of the assembly mechanism allows the first contact block and the second contact block to align and contact with each other through the contact between the guide post and the guide hole.

[0021] For examples, please refer to Figure 1-6 This utility model provides a technical solution: A corrosion-resistant and low-loss circuit board includes a circuit board body 1 and a base plate 2 disposed below the circuit board body 1. A first contact block 3 and a second contact block 4 are respectively disposed on the outer side of the circuit board body 1. A combination mechanism 5 is disposed between the first contact block 3 and the second contact block 4. An mounting block 401 and a slot 402 are respectively disposed on the outer side of the second contact block 4. An mounting post 201 and a support post 202 are respectively fixedly installed on the inner wall of the bottom end of the base plate 2. A reset spring 203 and a slot 204 are respectively movably sleeved on the outer side of the support post 202. Specifically, the second contact block 4 is located on the front and rear sides of the circuit board body 1, and the second contact block 4 is U-shaped. The inner wall of the second contact block 4 is in contact with the surface of the circuit board body 1. The first contact block 3 is located on the left and right sides of the circuit board body 1. Both the first contact block 3 and the second contact block 4 are made of rubber material. The surface of the circuit board body 1 is coated with a corrosion-resistant coating. In this embodiment, the corrosion resistance of the circuit board body 1 can be improved by the corrosion-resistant coating.
[0022] Specifically, the mounting posts 201 are located on the inner wall side of the base plate 2, and the top of the mounting posts 201 fits through the bottom surface of the mounting block 401 and extends upward. The two ends of the return spring 203 are fixedly in contact with the bottom surface of the locking block 204 and the bottom end of the inner wall of the base plate 2, respectively. The locking block 204 is in sliding contact with the inner wall of the slot 402. In this implementation plan, such as Figure 2 and Figure 4As shown, the mounting post 201 is designed to fit and contact the inner wall of the mounting block 401, thereby achieving the function of positioning the second contact block 4. At the same time, the reset spring 203 can apply an elastic force to the locking block 204, causing the locking block 204 to move towards the locking groove 402, thereby achieving the function of fixing the circuit board body 1.
[0023] In this embodiment, please refer to Figure 1 , Figure 4 , Figure 5 and Figure 6 The combined mechanism 5 includes a guide post 501, a guide hole 502, a moving groove 503, and a positioning hole 504. The guide post 501 is fixedly installed on the left and right sides of the inner wall of the second contact block 4. The guide hole 502 is opened at the front and rear ends of the first contact block 3. The moving groove 503 is opened on the top surface of the first contact block 3. The moving groove 503 is provided with a support spring 505 and a positioning post 506. The positioning hole 504 is opened on the top surface of the second contact block 4. Specifically, the outer surface of the guide post 501 is fitted and contacted with the inner wall of the guide hole 502, the two ends of the support spring 505 are respectively fixed to the bottom inner wall of the moving groove 503 and the bottom end of the positioning post 506, the bottom inner wall of the positioning hole 504 extends to the inner side of the second contact block 4, and the inner wall of the positioning hole 504 is in close contact with the outer surface of the positioning post 506. In this implementation plan, such as Figure 5 and Figure 6 As shown, the guide post 501 is designed to contact the inner wall of the guide hole 502, allowing the first contact block 3 and the second contact block 4 to align and contact. The support spring 505 supports the positioning post 506, causing the positioning post 506 to contact the positioning hole 504. This achieves the function of fixing the first contact block 3 and the second contact block 4, making it easier for the first contact block 3 and the second contact block 4 to be fitted onto the outer surface of the circuit board body 1, thus meeting the protection requirements of the circuit board.
[0024] The working process of this utility model is as follows: When using a corrosion-resistant, low-loss circuit board, the second contact block 4 is moved to contact the front and rear sides of the circuit board body 1. Simultaneously, the first contact block 3 is moved to bring it close to the left and right ends of the circuit board body 1. During this close-up process, the guide post 501 is ensured to engage with the guide hole 502. As engagement progresses, the positioning post 506 contacts the inner wall of the second contact block 4 and compresses the support spring 505. The support spring 505 then applies an upward force to the positioning post 506 until it moves below the positioning hole 504. At this point, supported by the support spring 505, the positioning post 506 contacts the positioning hole 504. The first contact block 3 and the second contact block 4 protect the circuit board body 1 by wrapping it. Then, the circuit board body 1 is brought close to the base plate 2. The mounting block 401 at the bottom of the second contact block 4 is aligned with the mounting post 201 on the base plate 2 and placed downwards so that the mounting post 201 passes through the mounting block 401, providing initial positioning and support. During the downward pressing process, the locking block 204 is moved to the top of the slot 402 and the return spring 203 is stretched. The stretched return spring 203 can apply an elastic force to the locking block 204, causing the locking block 204 to gradually and tightly fit along the inner wall of the slot 402, thereby firmly locking the circuit board body 1 onto the base plate 2 and meeting the subsequent maintenance needs.
[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
