Circuit boards establish electrical connections between electronic components through structures such as wires, traces, and pads. As a basic component of electronic devices, circuit boards can provide mechanical support and fixation.

[0003] After searching, a Chinese patent with publication number CN219478190U discloses a double-sided circuit board that is easy to install. When installing the circuit board body, the snap-in protrusion at the bottom of the reinforcement base is snapped into the inside of the snap-in through hole on the side of the circuit board body that needs to be fixed, and then the self-adhesive strip can be adhered to the surface of the installation position. Then the self-adhesive strip will be adhered together with the circuit board body near the position where it needs to be installed, so that the reinforcement base will not shake easily, thereby improving the stability during the subsequent installation process. After the installation is completed, the reinforcement base can be torn off and the circuit board body can continue to be used, thereby improving the stability during use.

[0022] The following will disclose multiple embodiments of the utility model with diagrams. For the purpose of clear description, many physical details will be described together in the following description. However, it should be understood that these physical details should not be used to limit the utility model. In other words, in some embodiments of the utility model, these physical details are not necessary. In addition, for the purpose of simplifying the diagram, some conventional structures and components will be depicted in a simple schematic manner in the diagram.

[0023] See also Figure 1 , Figure 2 The utility model is a double-sided circuit board that is easy to install, including a circuit board body 1, a base 2 is arranged below the circuit board body 1, a mounting hole 4 is arranged on the base 2, a through hole 3 is arranged on the circuit board body 1, a positioning cylinder 6 is arranged inside the mounting hole 4, a notch 7 is arranged on the positioning cylinder 6, a fixing bolt 5 is arranged inside the positioning cylinder 6, and a limiting member is arranged between the positioning cylinder 6 and the mounting hole 4.

[0024] When installing the circuit board body 1, the staff aligns the positioning tube 6 with the mounting hole 4 and then inserts the positioning tube 6 into the mounting hole 4 to achieve the effect of convenient positioning and connection. Then the staff inserts the fixing bolt 5 into the positioning tube 6 and drives the fixing bolt 5 to rotate through a tool. The fixing bolt 5 gradually descends while rotating. The fixing bolt 5 drives the positioning tube 6 to expand toward the inner wall of the mounting hole 4 while descending. The positioning tube 6 pressurizes the inner wall of the mounting hole 4 and reinforces the position between the positioning tube 6 and the mounting hole 4 through a limit piece to achieve positioning and fixing at the same position, thereby reducing the overall occupied area of ​​the circuit board body 1 and reducing material costs.

[0025] like Figure 3 , Figure 4 As shown, the limiting member includes a protrusion 8, which is installed on the outside of the positioning cylinder 6. A fixing groove 9 is provided on the inner wall of the mounting hole 4 at the position corresponding to the protrusion 8. When the fixing bolt 5 drives the positioning cylinder 6 to expand, the positioning cylinder 6 drives the protrusion 8 to follow the movement, so that the protrusion 8 is inserted into the fixing groove 9, thereby achieving the position fixation between the positioning cylinder 6 and the base 2, and preventing the positioning cylinder 6 from sliding in the mounting hole 4.

[0026] There are multiple protrusions 8 and fixing grooves 9, which are evenly distributed, increasing the contact area between the positioning cylinder 6 and the base 2, and improving the connection stability between the circuit board body 1 and the base 2. The protrusions 8 and the fixing grooves 9 are both arranged in a ring shape. When disassembling the circuit board body 1, the fixing bolts 5 are first removed and then the circuit board body 1 is driven to rise. The positioning cylinder 6 of the circuit board body 1 follows the movement, so that the protrusion 8 shrinks under the action of the arc surface of the fixing groove 9, thereby realizing the separation of the protrusion 8 and the fixing groove 9.

[0027] Replay Figure 2 As shown, a ring 10 is provided at the upper end of the positioning cylinder 6, a notch 11 is provided at the upper end of the ring 10, the through hole 3 is stepped, and the ring 10 is threadedly connected to the inner wall of the through hole 3. When damage occurs on the positioning cylinder 6, the staff drives the ring 10 to rotate by a tool, so that the ring 10 is gradually separated from the through hole 3, and drives the positioning cylinder 6 to move upward, so that the positioning cylinder 6 can be taken out, and after one end of the new positioning cylinder 6 passes through the through hole 3, the ring 10 is driven in reverse to rotate, so that the positioning cylinder 6 can be fixed.

[0028] Four through holes 3 are arranged on the circuit board body 1, and positioning cylinders 6 are arranged on the inner sides of two of the four through holes 3, and sleeves 12 are arranged on the inner sides of the remaining two through holes 3. A circular ring 2 13 is arranged on the upper end of the sleeve 12, and the circular ring 2 13 has the same structure as the circular ring 10. The position between the circuit board body 1 and the base 2 is limited by the two positioning cylinders 6, and at the same time, the number of positioning cylinders 6 inserted into the mounting holes 4 can be reduced, thereby improving the accuracy and efficiency of installation. By driving the circular ring 10 and the circular ring 2 13 components to rotate, the corresponding positioning cylinders 6 and sleeves 12 can be used for disassembly and installation, so as to realize the position adjustment between the sleeve 12 and the positioning cylinder 6, facilitate the position adjustment according to actual needs, and increase the application range of the circuit board body 1.

[0029] like Figure 3 As shown, the length of the fixing bolt 5 is greater than the length of the positioning tube 6, and the lower end of the fixing bolt 5 is threadedly connected to the lower part of the mounting hole 4. By connecting one end of the fixing bolt 5 to the base 2, the connection stability between the base 2 and the circuit board body 1 is improved.

[0030] like Figure 2 As shown, there are multiple notches 7 on the positioning tube 6, and the multiple notches 7 are evenly distributed, so that the positioning tube 6 is evenly stressed, which is convenient for driving the positioning tube 6 to expand, and the lower end of the positioning tube 6 is chamfered to facilitate guiding the positioning tube 6 into the mounting hole 4.

[0031] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
