Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, and in particular to a circuit board with a protective structure. Background Technology

[0002] As a key component of electronic systems, printed circuit boards (PCBs) are widely used in communication equipment, computers, consumer electronics, industrial control, and other fields. The rationality of their design directly affects the performance stability, space utilization, and operational reliability of electronic devices. Based on circuit complexity and functional requirements, PCBs can be divided into single-sided boards, double-sided boards, and multilayer boards. Among them, multilayer boards, through interlayer interconnection structures, can integrate more complex circuit systems to meet the technical requirements of high-end electronic devices.

[0003] However, in the existing technology, the overall structure formed after the potting compound has cured lacks a detachable design, making it extremely difficult to replace individual faulty components during maintenance. The cured potting compound is hard and has no clear separation boundary. Forcibly disassembling it is not only time-consuming and laborious, but also easily damages adjacent components, conductive lines on the circuit board, or even the entire board, greatly increasing maintenance costs and wasting resources. It also hinders the regular testing and functional upgrades of the circuit board, resulting in extremely poor flexibility. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a circuit board with a protective structure, comprising:

[0006] A protective shell, on which a circuit board plug is slidably connected, and on which a spring contact is fixedly connected;

[0007] The outer casing disassembly assembly includes a base fixedly connected inside the protective casing, a sliding plate slidably connected to the base, a pressing plate fixedly connected to the sliding plate via a hook rod, an upper sliding plate fixedly connected to the sliding plate, a transmission block slidably connected to the upper sliding plate, the transmission block slidably connected to the circuit board plug via a connecting rod, and a transmission frame fixedly connected to the sliding plate.

[0008] In a preferred embodiment, the circuit board plug has a slot, and a spring is fixedly connected to the connecting rod. The spring on the connecting rod is slidably connected to the slot on the circuit board plug.

[0009] The above technical solution employs a spring clip to secure the base during use.

[0010] In a preferred embodiment, a pressing plate is fixedly connected to the transmission frame, and an opening is provided on the protective shell near the pressing plate. The pressing plate is slidably connected to the opening on the protective shell.

[0011] The above technical solution is adopted: when in use, a pressing plate is fixedly connected to the transmission frame, and the circuit board plug body can be fixed by directly pressing down the pressing plate.

[0013] The above technical solution is adopted: during use, a protective shell and a sliding rod on the base are provided to facilitate the displacement of the series rod, thereby causing the circuit board plug to move.

[0014] In a preferred embodiment, the end of the sliding rod away from the upper slide plate is slidably connected to the spring contact on the circuit board plug, and both the upper and lower ends of the transmission block are slidably connected inside the protective shell.

[0015] The above technical solution is adopted: In use, the end of the sliding rod away from the upper slide plate is slidably connected to the spring contact on the circuit board plug, so that the spring contact can be locked by the sliding rod to realize the connection of the circuit board plug.

[0018] In a preferred embodiment, a vertical rod is fixedly connected to the transmission frame, a fixed frame is slidably connected to the vertical rod, a return spring is fixedly connected between the vertical rod and the fixed frame, and a circular hole is opened on the protective shell near the vertical rod, with the vertical rod slidably connected in the circular hole on the protective shell.

[0019] The above technical solution employs a reset spring to adjust the position of the vertical rod during use.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0021] In terms of protective performance, this utility model provides a physical barrier for circuit boards and electronic components, blocking external dust, moisture, and mechanical impacts. This prevents oxidation, corrosion, or physical damage caused by direct exposure of components, significantly improving the stability and service life of the circuit board. It also overcomes the shortcomings of existing technologies that lack protective structures. The shell disassembly assembly achieves non-destructive operation through a mechanical linkage structure. During installation, simply pressing the pressing plate drives the transmission frame, sliding plate, and other components to engage the connecting rod with the circuit board connector spring and secure it with bolts, eliminating the need for potting compound. During disassembly, simply removing the bolts and lifting the sliding plate allows the sliding rod to disengage from the spring, separating the circuit board connector from the protective shell. The entire process avoids forced disassembly after the potting compound has cured, preventing damage to the circuit board, adjacent components, and conductive lines. This significantly reduces maintenance difficulty and costs, and minimizes resource waste. Attached Figure Description

[0031] 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.

[0032] like Figure 1-5 As shown, this utility model provides a technical solution: a circuit board with a protective structure, comprising:

[0033] A protective shell 1 is slidably connected to a circuit board plug 11, and a spring contact is fixedly connected to the circuit board plug 11.

[0034] The outer shell disassembly assembly 2 includes a base 21 fixedly connected inside the protective shell 1, a sliding plate 25 slidably connected to the base 21, a pressing plate 23 fixedly connected to the sliding plate 25 via a hook rod 26, an upper slide plate 29 fixedly connected to the sliding plate 25, a transmission block 28 slidably connected to the upper slide plate 29, the transmission block 28 slidably connected to the circuit board plug 11 via a connecting rod 27, and a transmission frame 22 fixedly connected to the sliding plate 25.

[0035] In this invention, during installation, pressing the pressing plate 23 causes the transmission frame 22 to slide down. The transmission frame 22 then causes the sliding plate 25 to slide down via the hook rod 26. The sliding plate 25 then causes the upper slide plate 29 to slide in the inclined groove of the transmission block 28, causing the transmission block 28 to slide inside the protective shell 1 and causing the connecting rod 27 to move away from the circuit board plug 11. Finally, the circuit board plug 11 is moved into the protective shell 1 and contacts the sliding rod 210, so that the shell disassembly component 2 is engaged with the circuit board plug 11 spring. Finally, the upper slide plate 29 is fixed with bolts to complete the installation. The entire process does not rely on potting compound. During disassembly, the bolts only need to be removed from the outside of the protective shell 1, and the upper slide plate 29 is lifted to disengage the sliding rod 210 from the circuit board plug 11 spring, thus separating the circuit board plug 11 from the protective shell 1. This transmission method avoids forced disassembly after the potting compound has cured, and will not cause damage to the circuit board, adjacent components and conductive lines, greatly reducing the difficulty and cost of maintenance and reducing resource waste.

[0036] The circuit board plug 11 has a slot, and a spring is fixedly connected to the connecting rod 27. The spring on the connecting rod 27 is slidably connected in the slot on the circuit board plug 11. When in use, the spring is provided to make it easy to lock the base 21.

[0037] A pressing plate 23 is fixedly connected to the transmission frame 22. An opening is provided on the protective shell 1 near the pressing plate 23. The pressing plate 23 is slidably connected in the opening on the protective shell 1. When in use, the pressing plate 23 is fixedly connected to the transmission frame 22. When in use, the pressing plate 23 can be pressed down directly to fix the circuit board plug 11 body.

[0038] A sliding rod 210 is slidably connected to the protective shell 1 and the base 21. A series plate 211 is fixedly connected to the sliding rod 210. An upper slide plate 29 is fixedly connected to the bottom of the sliding rod 210. The upper slide plate 29 is slidably connected to the bottom of the base 21. In use, by setting the sliding rod 210 on the protective shell 1 and the base 21, it is easy to drive the series rod 27 to move, so that the circuit board plug 11 will move.

[0039] The end of the sliding rod 210 away from the upper slide plate 29 is slidably connected to the spring piece on the circuit board plug 11. Both the upper and lower ends of the transmission block 28 are slidably connected inside the protective shell 1. In use, by setting the end of the sliding rod 210 away from the upper slide plate 29 to be slidably connected to the spring piece on the circuit board plug 11, it is easy to use the sliding rod 210 to hold the spring piece in place and realize the connection of the circuit board plug 11.

[0040] A slot is provided on the side of the protective shell 1 near the sliding plate 25. The sliding plate 25 is slidably connected in the slot on the protective shell 1. A connecting spring 24 is fixedly connected to the bottom of the sliding plate 25. The side of the connecting spring 24 away from the sliding plate 25 is fixedly connected to the protective shell 1. In use, the slot on the side of the protective shell 1 near the sliding plate 25 is used to limit the sliding position of the sliding plate 25.

[0041] A vertical rod 31 is fixedly connected to the transmission frame 22, and a fixed frame 3 is slidably connected to the vertical rod 31. A return spring 32 is fixedly connected between the vertical rod 31 and the fixed frame 3. A round hole is opened on the protective shell 1 near the vertical rod 31. The vertical rod 31 is slidably connected in the round hole on the protective shell 1. During use, the position of the vertical rod 31 can be adjusted by setting the return spring 32.

[0042] Working principle:

[0043] like Figure 1-5As shown, during use, after inserting the USB component into the circuit board plug 11, pressing the pressing plate 23 causes the pressing plate 23 to drive the transmission frame 22 to slide down, causing the transmission frame 22 to drive the sliding plate 25 to slide down via the hook rod 26, causing the sliding plate 25 to drive the upper slide plate 29 to slide down, causing the upper slide plate 29 to slide in the inclined groove on the transmission block 28, causing the transmission block 28 to slide inside the protective shell 1, causing the transmission block 28 to drive the connecting rod 27 to move, causing the connecting rod 27 to slide away from the circuit board plug 11, causing the connecting rod 27 to push the circuit board plug 11 to slide into the protective shell 1, so that the circuit board plug 11 contacts the sliding rod 210 of the protective shell 1, the shell disassembly component 2 is inserted into the spring piece on the circuit board plug 11, and the two ends of the upper slide plate 29 are fixed from both sides of the protective shell 1 with bolts to complete the installation;

[0044] When it is necessary to disassemble it, simply remove the bolts from the outside of the protective shell 1 and lift the upper slide plate 29 to disengage the sliding rod 210 from the spring on the circuit board plug 11.
