Description

Technical Field

[0001] This invention relates to circuit board protection, and more particularly to a circuit board pin protection device. Background Technology

[0002] Circuit boards, also known as printed circuit boards (PCBs), are indispensable components in modern electronic devices. The insulating material of the circuit board substrate isolates the conductive copper foil layer on the surface, allowing current to flow through various components along pre-designed paths, thereby achieving functions such as power generation, amplification, attenuation, modulation, demodulation, and encoding.

[0003] Common packages for components soldered onto circuit boards include through-hole packages and surface-mount packages. Circuit boards have pads; when soldering through-hole packages, the leads are aligned and pass through the pads, from one side of the circuit board to the other. When there are many leads and they are densely packed, dust and foreign matter can easily accumulate, posing a risk of short circuits between the leads.

[0004] In summary, designing a protective device that can prevent short circuits on the pins of a circuit board is a technical problem that needs to be solved. Summary of the Invention

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0027] The present invention provides a circuit board pin protection device, which is installed on a circuit board 3 and includes a protection part 1 and a mounting part 2, wherein the mounting part 2 is disposed on the side of the protection part 1.

[0028] like Figure 3 As shown, components are soldered on the circuit board 3, and one end of the pin 32 of the components passes through the circuit board 3. The area where the pins 32 are concentrated is the first area 31.

[0029] A protective section 1 is installed over the first region 31. The protective section 1 includes a protective plate 11 that encloses a cavity. The pins 32 are located within the cavity, and the edge of the protective plate 11 is in close contact with the surface of the circuit board 3. To ensure that the protective section 1 can contact the circuit board 3, completely isolate the pins 32 from the external environment, and prevent interference with other components on the circuit board 3, the thickness of the protective plate 11 is less than the distance between the first region 31 and other components on the circuit board 3, and the height of the protective section 1 is greater than the length of the pins 32 extending out of the circuit board 3. To ensure that the protective section 1 completely covers all pins 32, the shape of the projection of the protective section 1 onto the circuit board 3 is the same as the shape of the first region 31. Figure 1 and Figure 2 As shown, the first region 31 is rectangular, and the protective part 1 is cubic.

[0030] The mounting part 2 includes a mounting plate 21, on which a first mounting hole 22 is provided, such as Figure 4 As shown, two mounting plates 21 are located on opposite sides of the protective part 1 and are fixed in two opposite directions for a more stable installation. The surface of the mounting plate 21 overlaps with the circuit board 3. The circuit board 3 has a second mounting hole 33. The connector 4 passes through the first mounting hole 22 and the second mounting hole 33 to install the protective device on the circuit board 3. The connector 4 can be a bolt or nut for convenient and quick installation.

[0031] The protective part 1 and the mounting part 2 are made of transparent material, which can be polycarbonate (PC plastic). They are processed into an integrated structure by injection molding. The transparent material makes it easy to observe the pin 32. It has high hardness and can protect the pin 32, preventing damage to the pin 32 during product circulation and wiring. It also has good electrical performance and meets the insulation requirements.

[0032] This invention can prevent the pins 32 of the circuit board 3 from coming into contact with dust and foreign objects, effectively protecting the pins 32, improving the electrical performance of the circuit board 3, and enhancing product reliability.

[0033] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
