Description

Technical Field

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

[0002] Printed circuit boards (PCBs) are a crucial component of the electronics industry. Almost every electronic device, from small items like watches and calculators to large systems like computers, communication devices, and military weaponry, relies on PCBs for electrical interconnection with integrated circuits and other electronic components. A PCB consists of an insulating substrate, connecting wires, and solder pads for mounting and soldering electronic components, serving the dual purpose of conductive lines and an insulating substrate. It replaces complex wiring, enabling electrical connections between components in a circuit. This simplifies assembly and soldering, reduces the amount of wiring work required in traditional methods, significantly lessening the workload for workers; it also reduces overall size, lowers product costs, and improves the quality and reliability of electronic equipment. PCBs are mounted on machines using positioning holes pre-drilled during the PCB manufacturing process.

[0003] Existing technology, such as the patent with publication number CN222030117U, discloses a nested printed circuit board, including a circuit board body, two positioning holes, which are disposed on both sides of the surface of the circuit board body and are diagonally distributed between them; each positioning hole is provided with a positioning mechanism, which includes positioning grooves formed on the front and rear end walls of the positioning hole, positioning springs are provided on the left and right side walls of the positioning hole, the ends of the positioning springs are elastically connected to arc-shaped positioning plates, and the inner side of the positioning plates is provided with positioning rods with corrugated ends.

[0004] While the aforementioned existing technologies have significant beneficial effects, they still have shortcomings:

[0005] The aforementioned nested printed circuit board achieves a stable connection between the positioning hole and the positioning post by setting a positioning groove and a positioning plate inside the positioning hole. The positioning plate elastically compresses the positioning post, and the positioning groove embeds and tightens the positioning post, thus preventing displacement and loosening. However, the elastic clamping method using an elastic structure inside the positioning hole lacks damping, which makes the circuit board prone to shaking when the equipment with this circuit board is shaken. At the same time, the corrugated anti-slip structure on the inner wall of the positioning plate has vertically arranged textures, which are in the same direction as the inserted positioning post, making it easy to slide up and down and displace. This fails to effectively increase the friction, resulting in instability of the circuit board after installation. Therefore, a nested printed circuit board is proposed. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a nested printed circuit board. The board is held in place by locking frames within positioning stakes distributed around the perimeter of the board frame. Corresponding vertical and horizontal corrugated strips are installed in the center and side locking frames to form anti-slip strips in both directions, thereby increasing the friction force in different directions after the positioning stakes are clamped, ensuring stable clamping.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a nested printed circuit board, comprising a circuit board body, with positioning pin holes distributed around the perimeter of the circuit board body, each positioning pin hole including a positioning pin sleeve, and the positioning pin sleeve having an internal cavity, the bottom end of the cavity communicating with a positioning hole, and a center locking frame distributed on both sides of the inner wall of the cavity, the inner wall of the center locking frame having a vertical corrugated strip fixed thereon, the upper and lower sides of the center locking frame having side locking frames distributed thereon, the upper and lower ends of the side locking frames having sliding grooves, the inner wall of the side locking frames having a transverse corrugated strip embedded thereon, and the outer walls of the side locking frames having damping frames fixed on both sides, a compression spring connected to the center of the outer wall of the side locking frames, and a bolt threadedly connected to the top end of the positioning pin sleeve.

[0008] Preferably, the positioning stake sleeves are equidistantly distributed and fixed around the perimeter of the circuit board body, and the positioning stake sleeves are connected to the positioning holes through the sleeve cavity.

[0009] Preferably, the center locking bracket and the side locking bracket form an elastic structure with the inner walls on both sides of the sleeve cavity through compression springs, and the center locking bracket and the side locking bracket are symmetrically distributed along the inner walls on both sides of the sleeve cavity.

[0010] Preferably, the damping frame is fixed along both sides of the outer wall of the side clamping frame and the center clamping frame, and the damping frame is made of soft rubber.

[0011] Preferably, the side locking bracket slides into the inner walls of both sides of the sleeve cavity via a sliding groove, and both the side locking bracket and the center locking bracket are arc-shaped.

[0012] Preferably, the circuit board body includes a circuit board frame, and a pressure pin terminal is inserted into one side of the top surface of the circuit board frame. A component module is embedded in the other side of the top surface of the circuit board frame, and a slot is opened on the bottom surface of the component module. An adhesive frame is engaged at the four peripheral ends of the circuit board frame, and an inner frame is opened on the inner wall of the adhesive frame.

[0013] Preferably, the adhesive frame is engaged with the perimeter of the circuit board frame via an inner frame, and the adhesive frame is made of rubber.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model uses positioning pin sleeves distributed around the circuit board frame to assist in the stable connection with the positioning pins inside the installed housing. When the positioning pin is inserted into the sleeve cavity, it will be simultaneously engaged by the symmetrical center locking frame and side locking frame on both sides, and stably clamped with the elastic structure. At the same time, each set of center locking frame and side locking frame is connected to a damping frame on the outer wall, which provides damping under buffer through soft rubber material to maintain clamping stability. The center locking frame and side locking frame are equipped with corresponding vertical corrugated strips and horizontal corrugated strips to form horizontal and vertical anti-slip, thereby increasing the friction force in different directions after clamping the positioning pin, ensuring clamping stability and avoiding dislodgement.

[0016] 2. This printed circuit board uses the pin holes and slots on the surface of the circuit board frame to mount the pin terminals and component modules. The slots work together to keep the component modules structurally stable at the connection point after soldering, reducing the impact of the component modules. At the same time, the rubber frame around the four edges is secured by the inner frame, forming protection for the four edges of the circuit board during use. The rubber frame around the four edges of the printed circuit board is made of rubber material, which can protect the four edges and also provide insulation to prevent short circuits of the circuit board.

[0024] Please see Figure 1-4 This embodiment of a nested printed circuit board includes a circuit board body 1, with positioning pin holes 2 distributed around the circuit board body 1. The circuit board body 1 includes a circuit board frame 101, and a pressure pin terminal 102 is inserted into one side of the top surface of the circuit board frame 101. A component module 103 is embedded in the other side of the top surface of the circuit board frame 101, and a slot 104 is opened on the bottom surface of the component module 103. An adhesive frame 105 is engaged at the four peripheral ends of the circuit board frame 101, and an inner frame 106 is opened on the inner wall of the adhesive frame 105.

[0025] like Figure 1-4 As shown, the printed circuit board in this utility model is similar in structure to existing printed circuit boards, such as the nested printed circuit board disclosed in CN222030117U. The main improvement of this utility model is that the clamping frame 206 inside the positioning stake sleeve 201 distributed around the circuit board frame 101 maintains the clamping, while the middle clamping frame 204 and the side clamping frame 206 are equipped with corresponding vertical corrugated strips 205 and horizontal corrugated strips 208, thereby increasing the frictional force in different directions after clamping the positioning stakes and ensuring clamping stability; in this utility model, both the component module 103 and the pressure pin terminal 102 are As is the prior art, when using this printed circuit board, the pin terminals 102 and component modules 103 can be mounted through the pin holes and slots 104 on the surface of the circuit board frame 101. The slots 104 help to keep the component modules 103 structurally stable at the connection point after soldering, reducing the impact of the component modules 103. At the same time, the rubber frame 105 at the four perimeters is engaged by the inner frame 106, forming protection for the four perimeters of the circuit board during use. The rubber frame 105 of the printed circuit board is made of rubber, which can protect the four perimeters while also providing insulation to prevent short circuits of the circuit board.

[0026] like Figure 2-4As shown, the positioning pile hole 2 includes a positioning pile sleeve 201, and the positioning pile sleeve 201 has a cavity 202 inside. The bottom end of the cavity 202 is connected to the positioning hole 203. The inner walls of the cavity 202 are distributed with a central locking frame 204 on both sides. The inner wall of the central locking frame 204 is fixed with a vertical corrugated strip 205. The upper and lower sides of the central locking frame 204 are distributed with side locking frames 206. The upper and lower ends of the side locking frames 206 are provided with sliding grooves 207. The inner wall of the side locking frames 206 is embedded with a transverse corrugated strip. 208, and damping frames 209 are fixed on both sides of the outer wall of the side locking frame 206. A compression spring 210 is connected to the center of the outer wall of the side locking frame 206. A bolt 211 is threaded to the top of the positioning sleeve 201. When this nested printed circuit board is installed and used, the positioning sleeves 201 around the entire circuit board frame 101 can be inserted into the positioning pins inside the equipment housing. At this time, the positioning pins pass through the positioning holes 203 and enter the cavity 202 of the inner wall of the positioning sleeve 201. As they are inserted, the inner walls on both sides of the cavity 202... The center clamping bracket 204 and the side clamping bracket 206 are pressed in and retracted. After the positioning pin is inserted, the center clamping bracket 204 and the side clamping bracket 206 clamp and fix the positioning pin on both sides under the elastic pressure of the compression spring 210. At the same time, the bolt 211 can be rotated and tightened at the top to complete the installation. The nested printed circuit board can be stably connected to the positioning pin in the installed housing by the positioning pin sleeves 201 distributed around the circuit board frame 101. When the positioning pin is inserted into the sleeve cavity 202, it will be subjected to the symmetrical center clamping on both sides. The center clamping frame 204 and the side clamping frame 206 engage simultaneously, with the elastic structure providing stable clamping. At the same time, each set of center clamping frames 204 and side clamping frames 206 has a damping frame 209 connected to its outer wall. The soft rubber material provides damping under buffer to maintain clamping stability. The center clamping frame 204 and the side clamping frame 206 are equipped with corresponding vertical corrugated strips 205 and horizontal corrugated strips 208 to form anti-slip in both directions, thereby increasing the friction in different directions after clamping the positioning pile, ensuring clamping stability and preventing dislodgement.
