Technical Field

[0001] The utility model relates to the technical field of circuit board manufacturing, in particular to a protective PCB substrate. Background Art

[0002] PCB substrate, full name is printed circuit board substrate, is the basic material that constitutes the printed circuit board (PCB). It is one of the key components in manufacturing PCB and is responsible for carrying and interconnecting electronic components. PCB substrate is usually made of insulating material. Its core purpose is to provide physical support and realize the layout of the circuit, while ensuring the electrical connection between various electronic components.

[0003] In the related art, in designs that require stacking or overlapping double-layer circuit boards, two PCB substrates are usually connected using support columns. For example, this design is used in space-constrained electronic products, servers, data center equipment, or complex industrial control and automation systems.

[0004] However, there are some problems with the way that the double-layer PCB substrate is connected only by connecting columns. For example, the protection on both sides is insufficient. When the sides of the double-layer PCB substrate are hit, scratched, or invaded by dust and moisture, short circuits, corrosion, or functional failures may occur. In addition, when the double-layer PCB substrate is moved and subjected to vibration, impact, or falling, the corners of the double-layer PCB substrate are often the most vulnerable parts. However, due to insufficient buffering, the PCB substrate and the components thereon may be impacted, which may cause failures. Summary of the invention

[0005] The utility model aims to solve one of the technical problems in the above-mentioned technology at least to a certain extent.

[0006] To achieve the above-mentioned purpose, the first aspect of the utility model proposes a protective PCB substrate, comprising: a substrate body, a connector, a connecting plate, a protective frame and a snap-on member, wherein the four corners of the two substrate bodies are respectively connected by the connector; the connecting member comprises a column, a nut sleeve and a rubber pad, wherein the column is arranged on the substrate body at the bottom and vertically passes through the substrate body at the top; the rubber pad is sleeved on the column, and the two ends of the rubber pad are respectively abutted against the two substrate bodies; the nut sleeve is threadedly locked on the top of the column; grooves are respectively opened in the middle of the sides of the two substrate bodies, the connecting plate is arranged in the groove and connects the two substrate bodies; the two protective frames are respectively arranged on both sides of the substrate body, and are respectively snap-connected with the corresponding connecting plates through the snap-on member.

[0007] In addition, the protective PCB substrate proposed in the utility model may also have the following additional technical features:

[0008] As a further description of the above technical solution: the protection frame is a U-shaped frame, and the corners at both ends of the protection frame are respectively wrapped around the two corners on the same side of the substrate body.

[0009] The inner wall of the protection frame is coated with an antistatic coating.

[0010] Each of the connecting plates is provided with two upper and lower opposite slots, and the buckle comprises a buckle straight arm, a buckle foot and a limit block, wherein one end of the two buckle straight arms is respectively connected to the protective frame, and the other end passes through the corresponding buckle slot, and the buckle feet are respectively provided on the opposite sides of the ends of the two buckle straight arms; the limit blocks are respectively provided on the opposite sides of the two buckle straight arms to limit the depth of the buckle straight arms extending into the corresponding buckle slots.

[0011] The substrate body is provided with heat sinks or heat dissipation holes.

[0012] The height of the protection frame is greater than the distance between the two substrate bodies.

[0013] The two substrate bodies are electrically connected via a conductive path.

[0014] According to the protective PCB substrate of the utility model, the detachable protective frames arranged on both sides can protect the two sides and corners of the double-layer structure of the substrate body, reducing the impact, scratches, dust or moisture intrusion on the side of the substrate body. In addition, when the double-layer substrate body is connected by a connector, when the double-layer structure of the substrate body is vibrated, impacted or dropped, the rubber pad can absorb energy to provide effective buffering, reduce the impact on the substrate body and the components thereon, and reduce the failure rate caused by this.

[0027] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0028] The protective PCB substrate of the embodiment of the utility model is described below with reference to the accompanying drawings.

[0029] like Figure 1 and Figure 2 As shown, the protective PCB substrate of the embodiment of the utility model may include a substrate body 100 , a connector 200 , a connecting plate 300 , a protective frame 400 and a buckle 500 .

[0030] The four corners of the two substrate bodies 100 are connected by connecting members 200 .

[0031] It should be noted that the two substrate bodies 100 are electrically connected via a conductive path, which is used to transmit signals or power between the two substrate bodies 100, thereby increasing the integration and functionality of the structure.

[0032] like Figure 6 As shown, the connecting member 200 includes a column 210 , a nut sleeve 220 and a rubber pad 230 .

[0033] Among them, the column 210 is set on the bottom substrate body 100 and vertically passes through the top substrate body 100 upward. The rubber pad 230 is sleeved on the column 210, and the two ends of the rubber pad 230 are respectively abutted against the two substrate bodies 100, and the nut sleeve 220 is threadedly locked on the top of the column 210.

[0034] It should be noted that a thread groove is provided at the top of the column 210. When the nut sleeve 220 is threadedly locked on the top of the column 210, the top substrate body 100 is pressed down by its own rotation, so that the top substrate body 100 is pressed tightly against the rubber pad 230, thereby achieving that the two ends of the rubber pad 230 are respectively in contact with the two substrate bodies 100.

[0035] like Figure 7 As shown, grooves 101 are respectively opened in the middle of the sides of the two substrate bodies 100 , and the connecting plate 300 is disposed in the groove 101 to connect the two substrate bodies 100 .

[0036] The two protection frames 400 are respectively disposed on two sides of the substrate body 100 , and are respectively connected to the corresponding connecting plates 300 through the fasteners 500 .

[0037] As a possible situation, two grooves 101 are provided on the same side of the two substrate bodies 100, and a connecting plate 300 is connected in each groove 101. Then, two snap fasteners 500 are provided on the corresponding protective frame 400 on the same side, and the two snap fasteners 500 are respectively connected to the corresponding connecting plates 300 to improve the installation stability of the protective frame 400.

[0038] Specifically, when the relevant staff installs the double-layer substrate body 100, they first connect the corners of the two substrate bodies 100 through the connecting piece 200, and then install the protective frame 400 by snapping it onto the connecting plate 300 through the snapping piece 500.

[0039] The protection frame 400 protects the sides of the two substrate bodies 100 , which can effectively prevent the substrate bodies 100 from being hit or scratched by the sides. In addition, due to the blocking of the protection frame 400 , the intrusion of dust and moisture can be reduced.

[0040] When the corners of the double-layer substrate body 100 are impacted, the corners of the two substrate bodies 100 are deformed and squeeze the rubber pads 230, so that the rubber pads 230 absorb energy and effectively buffer the corners of the substrate body 100, thereby reducing the impact on the substrate body 100 and the components thereon, and reducing the failure rate caused thereby.

[0041] It should be noted that heat sinks or heat dissipation holes are provided on the substrate body 100 to provide local enhanced heat dissipation for specific high-temperature components and ensure system stability.

[0042] In one embodiment of the present invention, the protection frame 400 is a U-shaped frame, and the two corners of the protection frame 400 are respectively wrapped around the two corners on the same side of the substrate body 100.

[0043] It should be noted that the protection frame 400 can not only protect the sides of the substrate body 100 , but also further protect the corners, thereby improving the impact resistance of the substrate body 100 .

[0044] In addition, the inner wall of the protection frame 400 is coated with an anti-static coating, which can effectively prevent static electricity accumulation and protect sensitive electronic components from being damaged by static electricity.

[0045] In another embodiment of the present invention, the height of the protection frame 400 is greater than the distance between the two substrate bodies 100, which can effectively block the intrusion of dust and moisture.

[0046] In one embodiment of the present invention, Figure 7 As shown, each connecting plate 300 is provided with two upper and lower opposite slots 301 .

[0047] like Figure 3 , Figure 4 , Figure 5 and Figure 8 As shown, the buckle 500 includes a buckle straight arm 510 , a buckle foot 520 and a limit block 530 .

[0048] Among them, one end of the two buckle straight arms 510 is respectively connected to the protective frame 400, and the other end passes through the corresponding slot 301, and buckle feet 520 are respectively provided on the opposite sides of the ends of the two buckle straight arms 510, and limiting blocks 530 are respectively provided on the opposite sides of the two buckle straight arms 510 to limit the depth of the buckle straight arms 510 extending into the corresponding slot 301.

[0049] It should be noted that when the relevant staff installs the protective frame 400, first, the relevant staff presses the two buckle straight arms 510 to deform and move closer to each other, and then pushes the buckle 500 to make the buckle feet 520 pass through the corresponding slots 301 until the limit block 530 abuts against the connecting plate 300, and then lets go, so that the two buckle straight arms 510 move away from each other and reset. At this time, the buckle feet 520 are limited by the slots 301, and due to the limiting effect of the limit block 530, the two can ensure the stability of the buckle 500 being connected to the connecting plate 300, thereby avoiding large-scale shaking of the buckle 500.

[0050] When removing the fastener 500, the relevant staff also presses the two fastener straight arms 510 so that the two fastener straight arms 510 are deformed and approach each other, and then pulls out the fastener 500 so that the fastener feet 520 are disengaged from the corresponding slots 301 to complete the disassembly. Through the installation of the fastener 500, the relevant staff can install or disassemble the protective frame 400 more quickly and conveniently.

[0051] In summary, according to the protective PCB substrate of the embodiment of the utility model, the detachable protective frame 400 arranged on both sides can protect the two sides and corners of the double-layer structure of the substrate main body 100, thereby reducing the side edges of the substrate main body 100 from collision, scratches, dust or moisture intrusion. In addition, when the double-layer substrate main body 100 is connected by the connector 200, when the double-layer substrate main body 100 is vibrated, impacted or dropped, the rubber pad 230 can absorb energy, provide effective buffering, reduce the impact on the substrate main body 100 and the components thereon, and reduce the failure rate caused thereby.
