Description

Technical Field

[0001] The utility model relates to the technical field of circuit boards, in particular to a circuit board with positioning holes. Background Art

[0002] Circuit boards are divided into FPC circuit boards and hard-flex boards. The hard-flex board is a flexible circuit board and a rigid circuit board. After processes such as pressing and other processes, they are combined together according to relevant process requirements to form a PCB with FPC characteristics.

[0003] After searching, a Chinese patent with publication number CN217957534U discloses a circuit board with positioning holes, the technical point of which is to solve the problem that although the circuit board can dissipate heat through several groups of heat sinks, the screws cannot be quickly aligned with the threaded columns.

[0004] In the above technology, the circuit board is fixed by screws. When the circuit board is fixed by screws, it is necessary to continuously twist the screws to connect with the fixing body during disassembly and assembly. Not only is the disassembly and assembly speed slow, but tools are also required for disassembly and assembly, which is not only time-consuming, but also troublesome to disassemble without tools.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

DETAILED DESCRIPTION

[0025] 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.

[0026] See also Figure 1-Figure 6 The utility model provides a circuit board with positioning holes, comprising a fixing plate 1, a circuit board body 2 and support columns 3 arranged at equal distances. The fixing plate 1 can be used to conveniently fix the circuit board body 2 and provide a fixing point for the circuit board body 2. The support columns 3 can be used to increase the fixing height of the circuit board body 2 to avoid short circuit caused by electric contact on the bottom surface of the circuit board body 2. The upper end of each support column 3 is fixedly connected with a card column 4, and the outer surface of each card column 4 is plugged with the circuit board body 2. The plugging of the card column 4 with the circuit board body 2 can facilitate the connection between the support column 3 and the circuit board body 2. A fixing column 5 is plugged into the interior of each support column 3, and the circuit board body 2 can be conveniently fixed by the setting of the fixing column 5.

[0027] In a preferred embodiment, the upper end of each fixing column 5 is fixedly connected with an upper plug 17, and the circuit board body 2 can be fixed and limited from the upper side through the upper plug 17. The lower end of each fixing column 5 is fixedly connected with a connecting column 6, and the lower plug 7 and the clamping ring 8 can be conveniently installed through the connecting column 6. The lower end of each connecting column 6 is fixedly connected with a lower plug 7, and the lower end of the clamping ring 8 can be conveniently limited through the lower plug 7. The outer surface of each connecting column 6 is sleeved with a clamping ring 8, and the position of the upper plug 17 can be fixed by moving the clamping ring 8 and misaligning the threaded head 12.

[0028] Please refer to 6. A sliding groove 9 is provided inside the connecting column 6. The sliding groove 9 can facilitate the sliding column 10 to move in the connecting column 6. Specifically, the inner wall of each sliding groove 9 is slidably connected with a sliding column 10. When the sliding column 10 moves, it can drive the retaining ring 8 to move synchronously. One end of each sliding column 10 away from the corresponding sliding groove 9 is fixedly connected to the corresponding retaining ring 8. The connection between the sliding column 10 and the retaining ring 8 can prevent the retaining ring 8 from rotating, thereby limiting the movement of the retaining ring 8.

[0029] In a preferred embodiment, a spring 11 is provided on the outer surface of each sliding column 10. The provided spring 11 can enable the connecting column 6 to apply elastic force to the retaining ring 8, so that the retaining ring 8 pops out when passing through the threaded head 12, thereby facilitating the misalignment of the retaining ring 8 and the threaded head 12. Specifically, both ends of each spring 11 are fixedly connected to the corresponding retaining ring 8 and the connecting column 6. The connection between the spring 11, the retaining ring 8 and the connecting column 6 can facilitate the installation and fixation of the spring 11.

[0030] See also Figure 1 , Figure 2 and Figure 4 The interior of the fixing plate 1 is provided with heat dissipation holes 18 and threaded holes 13 arranged at equal distances. The heat dissipation holes 18 can not only save the materials used in the fixing plate 1 and reduce the production cost, but also facilitate ventilation at the bottom of the circuit board body 2, thereby increasing the heat dissipation effect of the circuit board body 2. The upper surface of the fixing plate 1 is fixedly connected with positioning blocks 14 arranged at equal distances. The positioning blocks 14 can be used to conveniently locate the installation position of the circuit board body 2. The lower end of each support column 3 is fixedly connected with a threaded head 12. The threaded head 12 can facilitate the connection between the support column 3 and the fixing plate 1. Each support column 3 is threadedly connected through the threaded hole 13 corresponding to the threaded head 12. The threaded connection between the threaded head 12 and the threaded hole 13 can facilitate the connection and installation of the support column 3 and the fixing plate 1.

[0031] See also Figure 1 , Figure 2 and Figure 3 The inside of the circuit board body 2 is provided with limit grooves 15 and sockets 16 arranged at equal distances. The limit grooves 15 can be used to conveniently limit the installation position of the circuit board body 2, and the sockets 16 can be used to conveniently connect the circuit board body 2 with the card column 4. Specifically, the outer surface of each positioning block 14 is in sliding contact with the corresponding limit groove 15. Through the sliding contact between the positioning block 14 and the limit groove 15, the installation position of the circuit board body 2 is fixed between the four positioning blocks 14, and the outer surface of each card column 4 is plugged into the circuit board body 2 through the socket 16. The position of the circuit board body 2 can be limited from the inside to the outside through the connection between the card column 4 and the socket 16.

[0032] See also Figure 1 and Figure 2 The bottom surface of each upper plug 17 is in contact with the circuit board body 2. Through the contact between the upper plug 17 and the circuit board body 2, the upper plug 17 fixes the circuit board body 2 from the upper side to prevent the circuit board body 2 from moving upward. The upper surface of each clamping ring 8 is in contact with the bottom surface of the supporting column 3. Through the contact between the clamping ring 8 and the supporting column 3, the clamping ring 8 can easily prevent the upper plug 17 from moving upward through the connecting column 6 and the fixing column 5.
