Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, and specifically to a multilayer circuit board that can prevent circuit board displacement. Background Technology

[0002] With the trend of electronic devices becoming smaller and more integrated, multilayer circuit boards are widely used because they can achieve complex circuit connections.

[0003] However, traditional multilayer circuit boards have many problems during installation and use: the circuit boards are usually placed directly in the frame, lacking a stable limiting structure, and are easily displaced by external forces such as equipment vibration and handling, resulting in loose circuit connections and poor contact, affecting the normal operation of electronic equipment; some limiting devices use a fixed clamping structure, which cannot be adapted to circuit boards of different sizes, resulting in poor versatility; at the same time, multilayer circuit boards generate a lot of heat when working, and if heat dissipation is not timely, high temperature can easily lead to performance degradation or even damage; in addition, the adjustment operation of traditional limiting devices is cumbersome, and the installation and maintenance efficiency is low. Utility Model Content

[0004] Technical problems to be solved

[0005] In view of the above-mentioned shortcomings of the prior art, the present invention provides a multilayer circuit board that can prevent circuit board displacement, which can effectively solve the problems in the prior art.

[0006] Technical solution

[0007] This utility model provides a multilayer circuit board that can prevent circuit board displacement, including a frame body. The top of the frame body has side grooves on both sides. The top of the frame body is provided with a limiting component. The limiting component includes a threaded rod, a servo motor that is driven and fixed to one end of the threaded rod, and a locking structure disposed in the middle of the threaded rod. The threaded rod is disposed on the outside of the side grooves, and the locking structure includes an upper rotating arm, a lower rotating arm, and a sleeve shaft sleeved between the two. The ends of the upper rotating arm and the lower rotating arm are both fixed with pins. The bottom of the pins is fixedly connected to the top of the clamping block. The middle of the clamping block has a straight slot through which the threaded rod is fixed. The straight slot is disposed in the side groove.

[0008] Furthermore, the main frame is a hollow frame structure without a top face, and slots are provided through the left and right sides of the main frame, and fan assemblies are fixed on the front and rear sides of the main frame.

[0009] Furthermore, the top end of the pin is secured by a lock nut.

[0010] Furthermore, the straight slot is provided with a threaded structure, and the internal threads of the two sets of clamping blocks of the upper and lower rotating arms rotate in opposite directions.

[0011] Furthermore, both the upper and lower rotating arms have through holes on their other sides, and a sleeve shaft is fitted in the middle of both sets of through holes. A connecting plate is fitted on one side of the sleeve shaft, and the connecting plate is fixed to the outer wall of the frame body.

[0012] Furthermore, the servo motor is fixed to the outer wall of the frame body by a mounting bracket.

[0013] Beneficial effects

[0014] In this invention, a limiting assembly consisting of a servo motor, a threaded rod, and a clamping structure is provided. The servo motor drives the threaded rod to rotate, and the two sets of clamping blocks move relative to or towards each other along the side grooves by utilizing the opposite thread directions at the ends of the upper and lower rotating arms. This allows for tight clamping of multi-layer circuit boards of different sizes, effectively preventing the circuit boards from shifting due to vibration or external forces during use, ensuring the stability of the circuit connection. The position of the clamping blocks can be adjusted to accommodate multi-layer circuit boards of different sizes, eliminating the need to design a separate limiting structure for circuit boards of specific sizes, reducing usage costs, and increasing the applicability of the device. Grooves are opened on the left and right sides of the frame body, and fan assemblies are fixed on the front and rear sides. The grooves facilitate air circulation, and the fan assemblies accelerate the air circulation inside the frame body, quickly removing the heat generated by the circuit boards during operation, preventing high temperatures from affecting the performance of the circuit boards, and extending their service life.

[0022] The present invention will be further described below with reference to the embodiments.

[0023] Example: A multilayer circuit board that prevents circuit board displacement, see attached diagram. Figure 1 -Appendix Figure 4 The system includes a frame body 1, with side grooves 13 on both sides of the top end of the frame body 1. A limiting assembly 2 is provided at the top end of the frame body 1. The limiting assembly 2 includes a threaded rod 21, a servo motor 23 fixed to one end of the threaded rod 21, and a locking structure 22 located in the middle of the threaded rod 21. The threaded rod 21 is located outside the side grooves 13, and the locking structure 22 includes an upper rotating arm 221, a lower rotating arm 222, and a sleeve shaft 226 fitted between them. The lower rotating arm 222 has a pin 223 fixedly inserted at its end. The bottom of the pin 223 is fixedly connected to the top of the clamping block 224. The clamping block 224 has a straight slot 225 through its middle. A threaded rod 21 is fixed inside the straight slot 225. The straight slot 225 is set inside the side slot 13. The position of the clamping block 224 can be adjusted to adapt to multi-layer circuit boards of different sizes. There is no need to design a separate limiting structure for circuit boards of specific sizes, which reduces the cost of use and improves the applicability of the device.

[0024] The frame body 1 is a hollow frame structure without a top face, and slots 11 are opened through both the left and right sides of the frame body 1. Fan assemblies 12 are fixed on both the front and rear sides of the frame body 1. The circuit board is clamped between the clamping blocks 224. Multiple circuit board structures can be cooled by the fan assembly 12, and the heat can be dissipated from the slots 11 on both sides.

[0025] The top end of the pin 223 is fixed by a lock nut; the straight groove 225 has a threaded structure, and the internal threads of the two sets of clamping blocks 224 of the upper rotating arm 221 and the lower rotating arm 222 have opposite directions; the other side of the upper rotating arm 221 and the lower rotating arm 222 are both provided with through holes 227, and a sleeve shaft 226 is sleeved in the middle of the two sets of through holes 227. A connecting plate 228 is sleeved on one side of the sleeve shaft 226, and the connecting plate 228 is fixed to the outer wall of the frame body 1; the left and right sides of the frame body 1 have slots 11, and the front and rear sides are fixed with fan assemblies 12. The slots 11 facilitate air circulation, and the fan assemblies 12 accelerate the air circulation inside the frame body 1, which can quickly remove the wires. The heat generated by the circuit board during operation is prevented from affecting its performance due to high temperatures, thus extending its service life. A servo motor 23 drives the threaded rod 21 to achieve automatic adjustment of the clamping block 224, eliminating the need for cumbersome manual operation. The top of the pin 223 is fixed with a locking nut, facilitating the disassembly and maintenance of the upper rotating arm 221, lower rotating arm 222, and clamping block 224, improving installation and maintenance efficiency. The upper rotating arm 221 and lower rotating arm 222 are connected to the connecting plate 228 via a sleeve shaft 226. The connecting plate 228 is fixed to the outer wall of the frame body 1, ensuring the stability of the clamping structure 22. The threaded structure within the straight slot 225 fits tightly with the threaded rod 21, ensuring smooth movement of the clamping block 224 and improving the overall reliability of the device.

[0026] The servo motor 23 is fixed to the outer wall of the frame body 1 by a mounting bracket. By setting a limiting assembly 2 consisting of the servo motor 23, the threaded rod 21 and the clamping structure 22, the servo motor 23 drives the threaded rod 21 to rotate. By using the opposite thread directions in the clamping blocks 224 at the ends of the upper rotating arm 221 and the lower rotating arm 222, the two sets of clamping blocks 224 can move relative to or towards each other along the side groove 13. This can tightly clamp multi-layer circuit boards of different sizes, effectively preventing the circuit boards from shifting due to vibration, external force, etc. during use, and ensuring the stability of the circuit connection.
