Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, and in particular to a shock-resistant circuit board for preventing signal distortion. Background Technology

[0002] A circuit board, also known as a flexible circuit board, is a highly reliable and flexible printed circuit board made of polyimide or polyester film as the substrate. Through processes such as lamination, they are assembled according to relevant technological requirements to form a circuit board with both FPC and PCB characteristics. Most existing circuit board mounting methods use screws to fix the board to a base plate. This method has the drawback of poor bottom cushioning, which may damage the bottom of the circuit board when subjected to vibration, thus affecting its use. While common shock absorption methods often use springs, springs can only achieve shock absorption in one direction, and the shock absorption effect is not ideal. Therefore, this application proposes a shock-resistant circuit board for signal distortion prevention, which can solve the above problems. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a shock-resistant circuit board that prevents signal distortion.

[0004] The purpose of this utility model is achieved through the following technical solution: a signal distortion-proof shockproof circuit board, including a base plate and a circuit board. A fixing seat is installed at each of the four corners of the top surface of the base plate. An L-shaped shock-absorbing pad is installed at each of the four corners of the bottom surface of the base plate. Shock-absorbing strips are installed on both sides of the top surface of the four fixing seats. Reciprocating sliding seats are installed inside the four fixing seats. Up-and-down reciprocating locking pins are installed inside the four sliding seats. Multiple uniformly arranged through holes are opened on the two side walls of the four shock-absorbing pads. Multiple through cavities are opened inside the multiple shock-absorbing strips. The circuit board is placed on the four fixing seats, and the four locking pins are respectively engaged with the notches at the four corners of the circuit board.

[0005] Optionally, a long slot is provided at the center of each of the four sides of the outer surface of the base plate, and the four long slots are parallel.

[0006] Optionally, assembly seats are installed on both sides of the top surface of the four fixed seats, and the multiple shock-absorbing strips are slidably engaged with the multiple assembly seats respectively.

[0007] Optionally, a first spring is installed on one side of the inner wall of each of the four fixed seats, and the outer side of the spring is respectively installed with the outer side of the four sliding seats.

[0008] Optionally, the cross-sectional shape of the four locking pins is I-shaped, and a second spring is fitted on the outside of each of the four locking pins, which is located inside the sliding seat. The bottom surface of the upper end of each of the four locking pins is provided with an installation groove, and a protective pad is installed inside each of them.

[0009] This utility model has the following advantages:

[0010] This anti-distortion, shock-resistant circuit board is mounted on a base plate, with multiple shock-absorbing strips between them. The strips are semi-circular on the outside and have multiple through-cavities inside, allowing sufficient deformation space after being compressed to absorb the impact of the circuit board's vertical shaking. At the same time, L-shaped shock-absorbing pads are installed at the four corners of the base plate, with several through holes on the side walls of the pads. When the pads are compressed and deformed, the through holes deform, increasing the degree of deformation of the pads and dispersing the impact.

[0011] Fixed seats are installed at the four corners of the top surface of the base plate. Sliding seats are slidably installed inside the fixed seats, and locking pins that can move up and down are installed inside the fixed seats. After the circuit board is placed on the four fixed seats, the four locking pins can be locked and limited with the notches on the circuit board to prevent the circuit board from shifting or shaking during subsequent processing. This structure also makes it convenient to limit the arrangement of circuit boards of different specifications. Attached Figure Description
