Description

Technical Field

[0001] The utility model relates to the technical field of PCB circuit boards, in particular to a PCB circuit board with V-shaped pre-dividing grooves. Background Art

[0002] PCBs, also known as printed circuit boards, provide electrical connections for electronic components. Their design primarily involves layout design. The primary advantage of using PCBs is that they significantly reduce wiring and assembly errors, improving automation and productivity. PCBs with V-shaped pre-slots typically have V-shaped grooves pre-cut into the edges between adjacent layers or panels during PCB production. This V-shaped pre-slot, also known as V-cutting or V-groove cutting, is a crucial step in PCB manufacturing. Currently, PCBs with V-shaped pre-slots are typically fastened to a housing or designated equipment using bolts. However, if the PCB is damaged or requires repair, it requires external tools to remove multiple bolts one by one to remove the PCB for repair. Excessive force during removal or installation can cause the bolts to slip, making the process cumbersome. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figures 1-4 A PCB circuit board with a V-shaped pre-dividing groove comprises two vertical boards 1, a placement board 2 is arranged between the vertical boards 1, and a circuit board body 3 is placed on the placement board 2, a V-shaped groove 4 is opened on the surface of the circuit board body 3, and first fixing holes 5 are symmetrically opened on both sides of the top of the circuit board body 3; a groove 6 for limiting the two sides of the circuit board body 3 is opened on one side of the vertical board 1, and a second fixing hole 7 is opened at the bottom end of the inner part of the groove 6; a screw rod 8 is rotatably connected to the inner wall of the vertical board 1, and a moving block 9 is respectively threadedly connected to the surface of the screw rod 8, and the top of the moving block 9 is connected to a support bar 10 through a movable shaft, and the top of the support bar 10 is connected to a connecting plate 11 through a movable shaft, and the top of the connecting plate 11 is symmetrically provided with screw holes connected to the inside of the first fixing hole 5 and the second fixing hole 7. The fixing rod 12 can rotate the screw 8 to allow the moving block 9 threadedly connected on its surface to move inside the slide groove 13 through the slider 14, so that the moving block 9 drives the support bar 10 and the connecting plate 11 to move up and down, and the connecting plate 11 can be moved away from both sides of the surface of the circuit board body 3. At the same time, the fixing rod 12 at the bottom end of the connecting plate 11 can be taken out from the inside of the fixing hole, so as to facilitate the disassembly of the circuit board body 3 and facilitate its maintenance. The top of the moving block 9 is connected to the support bar 10 through a movable shaft, and the top of the support bar 10 is connected to the connecting plate 11 through a movable shaft. The connection through the movable shaft means that the top end of the moving block 9 and the bottom end of the connecting plate 11 are installed with a partition, and a movable shaft is installed on one side of the partition, and the two ends of the support bar 10 are respectively connected to the movable circles at two places.

[0032] Furthermore, a sliding groove 13 is provided on the inner wall of the vertical plate 1, and a slider 14 connected to the bottom end of the moving block 9 is slidably connected inside the sliding groove 13, so that when the screw 8 rotates, the moving block 9 threadedly connected on its surface can be limitedly moved inside the sliding groove 13 through the slider 14.

[0033] Furthermore, the threads on both sides of the screw 8 are arranged in opposite directions, so that when the screw 8 rotates, the moving blocks 9 on both sides of its surface can move towards each other or move away from each other at the same time.

[0034] Furthermore, a mounting plate 15 is installed between the vertical plates 1, and a cooling fan 16 is installed at the center of the mounting plate 15, which facilitates heat dissipation of the circuit board body 3 through the cooling fan 16. The cooling fan 16 is a miniature cooling fan 16 and does not generate large vibrations.

[0035] Furthermore, a through slot 17 is provided at the center of the placement plate 2 , which facilitates the air blown out by the heat dissipation fan 16 to reach the bottom end of the circuit board body 3 through the through slot 17 .

[0036] Furthermore, one side of the vertical plate 1 is connected to a limit plate 18, and a threaded hole 19 is provided at the top of the limit plate 18, which is convenient for passing a bolt through the threaded hole 19 to install the vertical plate 1 at a designated location of the housing or equipment.

[0037] Furthermore, the diameter of the fixing rod 12 is the same as the inner diameter of the first fixing hole 5 and the second fixing hole 7 , so as to avoid a gap between the fixing rod 12 and the fixing holes, which would cause the circuit board body 3 to shake or move.

[0038] Furthermore, a rubber pad is provided between the connecting plate 11 and the fixing rod 12 to prevent the connecting plate 11 from being squeezed and damaged when being moved to both sides of the circuit board body 3. The rubber pad can play a role of buffering protection.
