Description

Technical Field

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

[0002] Nested printed circuit boards (PCBs) refer to a group of PCBs that are stacked or nested together in a certain way. Nested PCBs are typically used in electronic devices that need to integrate multiple functional modules or components within a limited space to achieve higher integration and performance. Nested PCBs form an integral structure by stacking multiple single-layer or double-layer PCBs together to achieve more complex circuit design and functional integration.

[0003] Nested printed circuit boards can stack multiple circuit boards together to achieve multiple circuit functions in a limited space, saving overall size and making them suitable for applications with high space requirements. However, since the circuit boards of nested printed circuit boards are generally stacked together by special design, the distance between each circuit board is difficult to adjust. Moreover, the stacking of multiple PCBs can easily increase the maintenance difficulty of nested printed circuit boards. Therefore, we propose a nested printed circuit board. Utility Model Content

[0004] To address the problems mentioned in the background section, this invention provides a nested printed circuit board. This solves the problem that nested printed circuit boards are typically stacked together using a special design, making it difficult to adjust the distance between each board and increasing the maintenance difficulty of the nested printed circuit board.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a nested printed circuit board, including a substrate and an electronic component assembly. The electronic component assembly is mounted on the surface of the substrate. A slot is formed on the outer side of the substrate, and the slot is in contact with a block. A connecting rod is fixed on one side of the block. A first sliding groove is formed inside the connecting rod, and the first sliding groove is slidably connected to a sliding plate. A limiting sleeve is embedded in the lower side of the first sliding groove. A limiting bolt passes through the inside of the limiting sleeve, and one end of the limiting bolt is movably connected to the sliding plate through a bearing.

[0006] Preferably, a second groove is provided on one side of the first groove, and the second groove is slidably connected to the slider.

[0007] Preferably, the slider is fixed to the slide plate, and measuring plates are respectively embedded on both sides of the second slide groove.

[0008] Preferably, a connecting block is fixed between the two limiting bolts.

[0009] Preferably, a sealing groove is formed on the upper side of the substrate, and the sealing groove is in contact with the mating plate.

[0010] Preferably, a connecting pad is bonded to the outer side of the docking plate, and a fixing bracket is fixed to the upper side of the docking plate.

[0011] Preferably, a dustproof mesh is bonded to the outer side of the fixing frame, and a docking block is fixed to the lower side of the docking plate.

[0012] Preferably, the substrate has a docking groove on the side near the docking block, and the docking block is in contact with the docking groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This nested printed circuit board aligns the card block with the opening of the card slot, rotates the connecting block, and causes the connecting rod to drive the card block to engage with the card slot. By rotating the connecting block, the distance between each substrate is controlled, expanding the maintenance space between each substrate, making the nested printed circuit board easier to maintain. First, the docking block is aligned with the docking groove, so that the docking plate and the sealing groove form a sealed state. At the same time, the dustproof mesh is confined to the outside of the electronic component assembly, making the nested printed circuit board less susceptible to dust affecting signal transmission and circuit connection.

[0014] 1. This nested printed circuit board allows multiple circuit boards to be stacked together, thereby realizing multiple circuit functions in a limited space, saving overall size, and is suitable for applications with high space requirements. The card block and the card slot opening are connected. By rotating the connecting block, the connecting rod drives the card block to engage with the card slot, thus restricting the various substrates together. The operator can control the displacement distance of the connecting rod through the measuring plate, and can control the distance between the various substrates by rotating the connecting block. By increasing the distance between the various substrates, the maintenance space between the various substrates is expanded, making the nested printed circuit board easy to repair.

[0015] 2. When assembling the nested printed circuit board, the mating block is first mated with the mating groove, so that the mating plate can be easily positioned and mated with the sealing groove, so that the mating plate and the sealing groove form a sealed state. At the same time, the dustproof mesh is confined to the outside of the electronic component assembly, so that dust is not easily affected by the electronic component assembly, making the nested printed circuit board less susceptible to the influence of dust on signal transmission and circuit connection.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-3This utility model provides a technical solution: a nested printed circuit board, including a substrate 1 and an electronic component assembly 101. The electronic component assembly 101 is mounted on the surface of the substrate 1. A slot 2 is formed on the outer side of the substrate 1, which is in contact with a block 201. A connecting rod 202 is fixed to one side of the block 201. A first sliding groove 203 is formed inside the connecting rod 202, and the first sliding groove 203 is slidably connected to a slide plate 204. A limiting sleeve 205 is embedded in the lower side of the first sliding groove 203. A limiting bolt 206 passes through the inside of the limiting sleeve 205, and one end of the limiting bolt 206 is movable with the slide plate 204 through a bearing. The connection is as follows: a second slide groove 207 is provided on one side of the first slide groove 203, and the second slide groove 207 is slidably connected to the slider 208. The slider 208 is fixed to the slide plate 204. Measuring plates 209 are respectively embedded on both sides of the second slide groove 207. A connecting block 210 is fixed between two limiting bolts 206. The slot 2 and the locking block 201 are engaged. The inner wall spacing of the first slide groove 203 matches the diameter of the slide plate 204. The limiting sleeve 205 is threadedly connected to the limiting bolt 206, and the thread directions of the two adjacent limiting bolts 206 are opposite. The cross-sectional dimensions of the second slide groove 207 match the cross-sectional dimensions of the slider 208.

[0025] In specific implementation, according to Figures 1-3 Nested printed circuit boards can stack multiple circuit boards together, thereby realizing multiple circuit functions in a limited space, saving overall size, and are suitable for applications with high space requirements. The card block 201 is aligned with the opening of the card slot 2. Rotating the connecting block 210 causes the two limiting bolts 206 to rotate. The limiting sleeve 205 is threadedly connected to the limiting bolts 206, and the threads of the two adjacent limiting bolts 206 are in opposite directions, causing the two connecting rods 202 to move in opposite directions. The inner wall spacing of the first sliding groove 203 matches the diameter of the sliding plate 204, thus... When the connecting rod 202 moves, it is not easy to shake. At this time, the connecting rod 202 drives the locking block 201 to engage with the locking slot 2, so that each substrate 1 is restricted together. When the connecting rod 202 moves, the sliding plate 204 drives the slider 208 to slide along the second sliding groove 207, so that the slider 208 indicates the scale of the measuring plate 209. This allows the operator to control the displacement distance of the connecting rod 202 through the measuring plate 209. It also allows the operator to control the distance between each substrate 1 by rotating the connecting block 210. Furthermore, by increasing the distance between each substrate 1, the maintenance space between each substrate 1 is expanded, making the nested printed circuit board easier to repair.

[0026] Please see Figure 1 , Figure 4 , Figure 5 and Figure 6A sealing groove 3 is provided on the upper side of the substrate 1, and the sealing groove 3 is in contact with the mating plate 301. A connecting pad 302 is bonded to the outer side of the mating plate 301, and a fixing frame 303 is fixed on the upper side of the mating plate 301. A dustproof mesh 304 is bonded to the outer side of the fixing frame 303. A mating block 305 is fixed on the lower side of the mating plate 301. A mating groove 306 is provided on the side of the substrate 1 near the mating block 305, and the mating block 305 is in contact with the mating groove 306. The connecting pad 302 is made of rubber, and the connecting pad 302 is pressed against the sealing groove 3. The cross-sectional dimensions of the mating block 305 match the cross-sectional dimensions of the mating groove 306.

[0027] In specific implementation, according to Figure 1 , Figure 4 , Figure 5 and Figure 6 When the nested printed circuit board is assembled, the mating block 305 is first mated with the mating groove 306. The cross-sectional dimensions of the mating block 305 and the mating groove 306 are matched to make the mating block 305 less prone to shaking inside the mating groove 306. This makes it easy for the mating plate 301 to be positioned and mated with the sealing groove 3. When the mating plate 301 and the sealing groove 3 are mated, the connecting pad 302 is made of rubber and has a certain deformation capability. The connecting pad 302 is pressed against the sealing groove 3, so that the mating plate 301 and the sealing groove 3 form a sealed state. At the same time, the dustproof mesh 304 is restricted to the outside of the electronic component assembly 101, so that dust is not easily affected by the electronic component assembly 101. This makes the nested printed circuit board less susceptible to the influence of dust on signal transmission and circuit connection.

[0028] In summary, nested printed circuit boards can stack multiple circuit boards together to achieve multiple circuit functions within a limited space, saving overall size and making them suitable for applications with high space requirements. By aligning the card block 201 with the opening of the card slot 2 and rotating the connecting block 210, the various substrates 1 are bound together. The distance between the various substrates 1 is controlled by rotating the connecting block 210, expanding the maintenance space between the various substrates 1 and making the nested printed circuit board easier to repair. When assembling the nested printed circuit board, the docking block 305 is first aligned with the docking groove 306, so that the docking plate 301 and the sealing groove 3 form a sealed state. At the same time, the dustproof mesh 304 is confined to the outside of the electronic component assembly 101, making the nested printed circuit board less susceptible to dust affecting signal transmission and circuit connection. The contents not described in detail in this specification are prior art known to those skilled in the art.

[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
