Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, specifically to a high-frequency, high-speed printed circuit board. Background Technology

[0002] Traditional printed circuit boards (PCBs) have several drawbacks. During transportation, PCBs are subjected to bumps, stacking, and compression. Due to their limited structural strength, they are prone to bending and deformation. This not only damages the physical appearance of the PCB but may also cause internal circuit breakage, leading to electrical faults. In daily use, PCBs are frequently dropped accidentally. If the fragile copper layer directly impacts a hard object, it is prone to wear and peeling, which can damage electrical connections, affect the accurate transmission of high-frequency and high-speed signals, and significantly reduce equipment performance.

[0003] By designing reinforcement devices and using their internal supports to strengthen the overall structure, and by using the protrusions of the snap-fit ​​and plug-in devices to protect the circuit board, the copper layer of the circuit board is protected, thereby ensuring the stable operation of the circuit board. Utility Model Content

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this utility model is as follows: a high-frequency, high-speed printed circuit board, comprising: a board body, wherein through grooves are symmetrically formed in the wall of the board body, and limit grooves are symmetrically formed in the wall of the board body; a reinforcing device, wherein the outer wall of the reinforcing device is inserted into the inner wall of the board body, and the reinforcing device is used to protect the board body; the reinforcing device includes a locking device, wherein a plug-in device is inserted into the outer wall of the locking device, and the reinforcing device provides support from inside the board body, thereby strengthening the overall structural strength and enabling the circuit board to better withstand external forces such as compression and bending during transportation.

[0005] Preferably, the engaging device includes an insertion plate, the outer wall of which has a wrapping groove and an avoidance groove, and a connecting protrusion is fixedly connected to the outer wall of the insertion plate.

[0006] Preferably, the outer wall of the insertion plate is fixedly connected to the inner wall of the plate body through a limiting groove, the outer wall of the insertion plate is inserted into the outer wall of the plate body through a wrapping groove, and the outer wall of the insertion plate contacts the outer wall of the plate body through a clearance groove.

[0007] Preferably, the insertion device includes a square plate, a vertical plate is fixedly connected to the outer wall of the square plate, an insertion groove is formed on the outer wall of the vertical plate, a connecting groove is formed at the end of the square plate away from the vertical plate, the outer wall of the vertical plate is inserted into the inner wall of the plate through the through groove, the outer wall of the vertical plate is inserted into the outer wall of the insertion plate through the insertion groove, and the connecting protrusion contacts the outer wall of the square plate through the connecting groove. The locking device and the insertion device cooperate with each other. Due to the presence of the protruding parts of both, when the circuit board falls, the copper layer of the circuit board is effectively prevented from being directly impacted, ensuring the stability of the electrical performance of the circuit board.

[0008] The beneficial effects of this utility model are as follows:

[0009] 1. This utility model strengthens the overall structural strength by providing internal support from the board body through a reinforcement device, allowing the circuit board to better withstand external forces such as compression and bending during transportation.

[0010] 2.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0018] Example: Please refer to Figure 1 - Figure 5 This utility model provides a technical solution: a high-frequency, high-speed printed circuit board, comprising: a board body 1, with symmetrical through grooves 3 and limiting grooves 4 symmetrically formed in the wall of the board body 1; a reinforcing device 2, the outer wall of which is inserted into the inner wall of the board body 1, the reinforcing device 2 being used to protect the board body 1; the reinforcing device 2 includes a locking device 21, with a plug-in device 22 inserted into the outer wall of the locking device 21. During the installation of the reinforcing device 2, the locking device 21 is processed first, and the insertion plate 211 is carefully aligned with the limiting groove 4 of the board body 1 and inserted. During this process, the wrapping groove 212 smoothly embeds along the outer wall of the board body 1, and the avoidance groove 213 avoids protruding parts such as solder joints on the board body 1, thereby ensuring smooth insertion. The connecting protrusion 214 also reaches the designated position, so that the insertion plate 211 is fixed inside the board body 1. The insertion plate 211 provides support from inside the board body 1, strengthening the overall structural strength.

[0019] The engaging device 21 includes an insertion plate 211, an enclosing groove 212 and an avoidance groove 213 on the outer wall of the insertion plate 211, and a connecting protrusion 214 fixedly connected to the outer wall of the insertion plate 211.

[0020] The outer wall of the insertion plate 211 is fixedly connected to the inner wall of the plate body 1 through the limiting groove 4. The outer wall of the insertion plate 211 is inserted into the outer wall of the plate body 1 through the wrapping groove 212. The outer wall of the insertion plate 211 contacts the outer wall of the plate body 1 through the outer wall of the clearance groove 213.

[0021] The insertion device 22 includes a square plate 221, with a vertical plate 222 fixedly connected to the outer wall of the square plate 221. The outer wall of the vertical plate 222 has an insertion groove 223. The end of the square plate 221 away from the vertical plate 222 has a connecting groove 224. The outer wall of the vertical plate 222 is inserted into the inner wall of the plate body 1 through the through groove 3. The outer wall of the vertical plate 222 is inserted into the outer wall of the insertion plate 211 through the insertion groove 223. A connecting protrusion 214 contacts the outer wall of the square plate 221 through the connecting groove 224. To install the insertion device 22, pick up the square plate 221 and align the vertical plate 222 at one end of it with the through groove 223 of the plate body 1. When the through slot 3 is inserted, the vertical plate 222 smoothly enters the interior of the board 1 along the through slot 3 and extends until it contacts the locking device 21. At this time, the insertion slot 223 on the vertical plate 222, which continues to move, will complete the insertion with the insertion plate 211. The connecting protrusion 214 is inserted into the connecting slot 224 of the square plate 221, so that the locking device 21 and the insertion device 22 are tightly connected as one, which further reinforces the connection between the reinforcing device 2 and the board 1. Due to the presence of the protruding parts such as the connecting protrusion 214, the reinforcing device 2 will be the one to hit the ground when it falls, thus bearing the impact force first and effectively preventing the copper layer of the circuit board from being directly impacted.

[0022] Working principle:

[0023] During manufacturing, the plate 1 is formed, and in its production process, through grooves 3 and limiting grooves 4 are symmetrically cut in the wall in advance to prepare for the subsequent installation of the reinforcement device 2.

[0024] During the installation of reinforcement device 2, the locking device 21 is processed first. The insertion plate 211 is carefully aligned with the limiting groove 4 of the plate body 1 and inserted. During this process, the wrapping groove 212 is smoothly inserted along the outer wall of the plate body 1, and the avoidance groove 213 avoids protruding parts such as solder points on the plate body 1, thereby ensuring smooth insertion. The connecting protrusion 214 also reaches the designated position, so that the insertion plate 211 is fixed inside the plate body 1. The insertion plate 211 provides support from inside the plate body 1, which strengthens the overall structural strength and allows the circuit board to better withstand external forces such as squeezing and bending during transportation.

[0025] Next, install the plug-in device 22, pick up the square plate 221, align the vertical plate 222 at one end with the through groove 3 of the plate body 1 and insert it. The vertical plate 222 smoothly enters the interior of the plate body 1 along the through groove 3 and extends until it contacts the locking device 21. At this time, the plug-in groove 223 on the vertical plate 222, which continues to move, will complete the plug-in with the insert plate 211. The connecting protrusion 214 is inserted into the connecting groove 224 of the square plate 221, so that the locking device 21 and the plug-in device 22 are tightly connected as one, and the connection between the reinforcing device 2 and the plate body 1 is reinforced for the second time.

[0026] When the circuit board is accidentally dropped, the reinforcement device 2 can also play a protective role. Due to the presence of the protrusions such as the connecting bump 214, the reinforcement device 2 will hit the ground when the protrusions hit the ground, thus bearing the impact force first. This effectively avoids the copper layer of the circuit board being directly hit, thereby reducing the risk of damage to the copper layer, ensuring the stability of the electrical performance of the circuit board, and maintaining the stable transmission of high-frequency and high-speed signals.
