Description

Technical Field

[0001] The utility model relates to the technical field of circuit boards, in particular to a circuit board capable of preventing surface scratches. Background Art

[0002] Ultra-thin circuit boards are widely used in various electronic devices due to their high wiring density, light weight, and thinness. However, due to their thinness and lack of protective structures, they are prone to scratches due to external forces and stacking pressure during production, transportation, and transport.

[0003] To this end, various circuit boards with scratch-resistant structures have emerged. For example, Chinese patent CN 213907231U discloses an ultra-thin circuit board for easy storage. The circuit board comprises a base plate and a cover plate. The base plate is fixedly mounted with fixing plates on both sides, a plug-in board is fixedly mounted on the top of the fixing plates, and a plug-in slot is defined at the bottom of the fixing plates for the plug-in board. The adjacent sides of the two fixing plates each have a connecting slot for the cover plate. However, this type of circuit board requires multiple protective panels, resulting in a complex structure and high material consumption. Utility Model Content

[0004] Based on this, it is necessary to provide a circuit board that can prevent surface scratches in order to address the deficiencies in the prior art.

[0006] Furthermore, a bottom end limiting portion and an outer edge limiting portion are provided on the bottom surface of the soft rubber component. The outer edge limiting portion is arranged in a ring shape and is arranged on the outer peripheral edge of the bottom end limiting portion.

[0007] Furthermore, the outer surface of the outer edge limiting portion is arranged to be an outwardly expanding arc surface from top to bottom, and the outer edge limiting portion is arranged to be gradually thinner from top to bottom.

[0008] Furthermore, the top surface and the bottom surface of the bottom end limiting portion are both arranged horizontally, the top surface thereof is in contact with the bottom surface of the plate body, and the bottom surface thereof is in contact with the top surface of the next plate body.

[0009] Furthermore, the hard plastic piece is cylindrical, and two adjusting grooves on opposite sides are provided on its outer side, and the adjusting grooves extend from the top to the bottom of the hard plastic piece.

[0019] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] like Figures 1 to 3 As shown in FIG. 1 , which is a first embodiment of a scratch-resistant circuit board provided by the present invention, the scratch-resistant circuit board comprises a board body 10 and an auxiliary positioning member 20 detachably mounted on the board body 10. Positioning holes 11 are provided at the edges of the board body 10. The positioning holes 11 in this embodiment are conventional holes on the circuit board for positioning during installation.

[0021] The auxiliary positioning member 20 includes a soft rubber member 21 and a hard rubber member 22. The hard rubber member 22 is mounted on the soft rubber member 21. In this embodiment, the hard rubber member 22 is integrally formed on the soft rubber member 21, and the top and bottom surfaces of the soft rubber member 21 are both horizontally arranged. A bottom end limit portion 211 and an outer edge limit portion 212 are provided on the bottom surface of the soft rubber member 21. The outer edge limit portion 212 is annular and is arranged on the outer edge of the bottom end limit portion 211. The outer surface of the outer edge limit portion 212 is an outwardly expanding arc from top to bottom, and the outer edge limit portion 212 is gradually thinned from top to bottom. In this embodiment, the material of the soft rubber member 21 is silicone. A mounting hole 213 is provided in the middle of the bottom end limit portion 211. The diameter of the mounting hole 213 is matched with the hard rubber member 22 of another adjacent auxiliary positioning member 20 for installation.

[0022] The hard plastic member 22 is cylindrical in shape, with two opposing positioning grooves 221 formed on its outer surface. The positioning grooves 221 extend from the top to the bottom of the hard plastic member 22. The positioning grooves 221 separate the hard plastic member 22 into two extension blocks 222. The hard plastic member 22 is configured to be smaller on the outside and larger on the inside, thereby facilitating guided installation.

[0023] During installation, the hard plastic part 22 is inserted into the positioning hole 11 of the circuit board, and the soft plastic part 21 is placed below the circuit board. The hard plastic part 22 extends outward from the circuit board. During installation, the two extension blocks 222 are pressed inward and inserted into the mounting hole 213 of the soft plastic part 21 of the upper auxiliary positioning member 20. After installation, the two extension blocks 222 gradually expand outward and return to their original positions, contacting the wall of the mounting hole 213, so that the two are tightly mounted to a certain extent, rather than being able to be freely moved out. When stacking multiple boards, the hard plastic part 22 on the next circuit board will extend upward and be installed in the mounting hole 213 on the previous circuit board, and the bottom surface of the bottom limiter 211 on the previous circuit board will contact the top surface of the next circuit board, thereby increasing the contact area and improving the stability of the installation. In addition, the outermost surface of the outer edge limiter 212 extends beyond the outer surface of the circuit board. Therefore, when in use, the outer edge limiting portion 212 can protect and limit the outer surface of the circuit board, and the bottom limiting portion 211 can separate the upper and lower circuit boards to avoid the problems of upper and lower layers being stacked, inconvenient for exhaust and scratching the board surface.

[0024] like Figure 4 , which is the second embodiment of the present invention. The structure of the second embodiment is basically the same as that of the first embodiment, except that the hard plastic member 22a extends above the bottom limit portion 211a, and the mounting hole 213a is provided in the hard plastic member 22a, thereby improving the stability during installation compared to the first embodiment. In this embodiment, the soft plastic member 21a and the hard plastic member 22a are integrally formed by injection molding.

[0025] In summary, the present invention separates and positions the upper and lower stacked thin circuit boards by providing auxiliary positioning members 20. This not only maintains sufficient space between the upper and lower layers of the circuit boards, facilitating airflow and preventing scratches on the board surfaces, but also the outer edge limiting portion 212 of the soft rubber member 21 of the auxiliary positioning member 20 protrudes from the outside of the board body 10, thereby providing spacing, protection, and positioning of the sides when installed in a box. This utility model is highly practical and has significant potential for widespread adoption.

[0026] The above-described embodiments represent only two implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
