[0001] The utility model relates to the technical field of circuit board soldering, in particular to a perforating tool for circuit boards. Background Art

[0002] A circuit board, also known as a printed circuit board, is a support for connecting electronic components and circuits together, used to realize functions such as layout design of complex circuits and electrical signal transmission in electrical and electronic devices. A circuit board is a basic electronic component used to build and arrange circuit components with circuit diagrams, usually made of fiberglass as the base material and processed through processes such as copper plating, gold plating, and etching.

[0003] In the process of connecting an existing circuit board to an external wire, it is necessary to first pass the wire through the connection holes of the circuit board, and then use soldering to connect the wire to the circuit board as a whole. Usually, it is necessary to manually pass the wires through the connection holes one by one, which takes a lot of time and affects the soldering efficiency. Moreover, the wires are likely to slip out of the hand during the process, resulting in the need to reinsert them, wasting working time again. Therefore, the utility model proposes a perforating tool for circuit boards to solve the above problems. Summary of the Utility Model

A plurality of second positioning holes and first positioning holes are respectively provided inside the positioning plate and the movable plate. Insertion bars are symmetrically and fixedly connected to the bottom of the movable plate. Insertion holes are symmetrically provided on both sides of the positioning plate. The outer wall of the insertion bar is in clamping connection with the inner wall of the insertion hole.

[0007] Further improvement lies in that: The positions of the second positioning holes and the first positioning holes are offset front and back. The positions of the limiting holes and the second positioning holes are parallel up and down. One ends of the limiting holes, the second positioning holes, and the first positioning holes are all provided as arc surfaces.

[0008] A further improvement lies in that: the clamping mechanism includes a fixing plate and fastening bolts. One side of the support frame is provided with a fixing plate, and the two sides of the support frame are symmetrically inserted with fastening bolts. One end of each fastening bolt penetrates through the inside of the fixing plate and is threadedly connected with a nut.

[0012] The beneficial effect of the present utility model is that after the top end of the wire is clamped into the inside of the limiting hole, the bottom end of the wire is pushed into the inside of the second clamping hole. The movable plate is placed above the positioning plate, and the positions of the insertion strips and the insertion holes are parallel up and down. The movable plate is pushed downward, so that the insertion strips are inserted into the inside of the insertion holes. At this time, the first clamping holes and the second clamping holes in the movable plate and the positioning plate approach the outer wall of the wire.

[0020] According to Figures 1-5 As shown in the figure, this embodiment provides a perforating tool for circuit boards, including a base 1, a support frame 2, a connecting plate 3 and a limiting plate 4. A support frame 2 is provided on the top of the base 1, and a connecting plate 3 is fixedly connected to the top of the support frame 2 through a clamping mechanism. A limiting plate 4 is fixedly connected to the top of the connecting plate 3. A plurality of limiting holes 5 are provided on one side of the limiting plate 4. A clamping mechanism is provided on the outer side of the support frame 2. When using this perforating tool, first, the connecting plate 3 is clamped on the top of the support frame 2 through the clamping mechanism to fix the limiting plate 4 above the support frame 2. Then, multiple wires are clamped into the interior of the limiting holes 5 to initially limit the wires. After that, the positions of the wires are locked through the clamping mechanism to completely fix the wires in the limiting holes 5. In this way, all the wires can be aligned with the connection holes of the circuit board at one time, and all the wires can be inserted into the connection holes of the circuit board at one time, making the perforating process stable and efficient.

[0021] The clamping mechanism includes a fixing plate 11 and a fastening bolt 12. A fixing plate 11 is provided on one side of the support frame 2. The fastening bolts 12 are symmetrically inserted on both sides of the support frame 2. One end of the fastening bolt 12 penetrates out of the interior of the fixing plate 11 and is threadedly connected with a nut. The connecting plate 3 abuts against one side of the support frame 2, and then the fixing plate 11 abuts against one side of the connecting plate 3. A fastening bolt 12 is inserted into each side of the support frame 2 respectively. One ends of the two fastening bolts 12 penetrate out of both sides of the fixing plate 11 respectively. Then, nuts are screwed onto one ends of the fastening bolts 12 to clamp the fixing plate 11 and the support frame 2 by using the nuts, so as to fix the connecting plate 3 on the top of the support frame 2, and further install the limiting plate 4 connected to the top of the connecting plate 3 above the support frame 2.

[0022] The engaging mechanism includes a positioning plate 13, a movable plate 14, insertion holes 15 and insertion bars 16. The positioning plate 13 is fixedly connected to the outside of the support frame 2. The movable plate 14 is arranged on the top of the positioning plate 13. A plurality of second positioning holes 18 and first positioning holes 17 are respectively arranged inside the positioning plate 13 and the movable plate 14. The bottom of the movable plate 14 is symmetrically and fixedly connected with insertion bars 16. The two sides of the positioning plate 13 are symmetrically provided with insertion holes 15. The outer wall of the insertion bar 16 is engaged with the inner wall of the insertion hole 15.

[0023] The positions of the second positioning holes 18 and the first positioning holes 17 are offset front and back. The position of the limiting hole 5 is parallel to that of the second positioning hole 18 up and down. One ends of the limiting hole 5, the second positioning hole 18 and the first positioning hole 17 are all set as arc surfaces.

[0024] After the top end of the wire is engaged into the limiting hole 5, push the bottom end of the wire into the second positioning hole 18. Place the movable plate 14 above the positioning plate 13 and make the insertion bar 16 parallel to the insertion hole 15 up and down. Push the movable plate 14 downward, so that the insertion bar 16 is inserted into the insertion hole 15. At this time, the first positioning hole 17 and the second positioning hole 18 in the movable plate 14 and the positioning plate 13 approach the outer wall of the wire. Use their front-back offset structure to clamp the outer wall of the wire, and then completely fix the wire inside the limiting hole 5.

[0025] On one side of the limiting plate 4 away from the limiting hole 5, clamping blocks 6 are symmetrically arranged. One end of the clamping block 6 is provided with an inclined chamfer. Limiting mechanisms are symmetrically arranged at the bottom of the limiting plate 4.

[0026] The limiting mechanism includes a connecting block 7, a sliding groove 8, a telescopic rod 9 and a spring 10. The bottom of the clamping block 6 is fixedly connected with the connecting block 7. The sliding grooves 8 are symmetrically arranged on one side of the limiting plate 4 away from the limiting hole 5. The telescopic rods 9 are symmetrically and fixedly connected to both sides of the bottom of the limiting plate 4. The bottom end of the connecting block 7 penetrates into the sliding groove 8 and is fixedly connected with one end of the telescopic rod 9. The spring 10 is arranged on the outside of the telescopic rod 9. After the wire passes through the connection hole of the circuit board, use your hand to move the clamping block 6 to both sides of the connecting plate 3. The sliding groove 8 drives the connecting block 7 to slide inside the sliding groove 8. The connecting block 7 squeezes the telescopic rod 9 and the spring 10 into a compressed state. Insert the circuit board between the two clamping blocks 6. When you let go, use the elastic force of the spring 10 and the telescopic rod 9 to cooperate to drive the clamping block 6 to reset and clamp both sides of the circuit board to limit the circuit board and prevent the circuit board from suddenly shifting during the welding process and affecting the welding quality.

[0027] A set of threaded holes are symmetrically provided on both sides of the support frame 2 and the base 1, and a connecting bolt is threadedly connected inside the threaded holes. The support frame 2 is detachably connected to the base 1 through the connecting bolt. Place the support frame 2 on the top of the base 1, and align the positions of the threaded holes on the support frame 2 and the base 1. Screw the connecting bolt into the threaded hole. The connecting bolt penetrates through the inside of the support frame 2 and the base 1, connecting the support frame 2 and the base 1 into one body.

[0028] For the perforating tool for the circuit board, after the top end of the wire is clamped into the inside of the limiting hole 5, push the bottom end of the wire into the inside of the second positioning hole 18. Place the movable plate 14 above the positioning plate 13, and make the positions of the inserting strip 16 and the inserting hole 15 parallel up and down. Push the movable plate 14 downward, so that the inserting strip 16 is inserted into the inserting hole 15. At this time, the first positioning hole 17 and the second positioning hole 18 in the movable plate 14 and the positioning plate 13 approach the outer wall of the wire, and the outer wall of the wire is clamped by their front and rear offset structures, and then the wire is completely fixed inside the limiting hole 5. In this way, all the wires can be aligned with the connection holes of the circuit board at one time, and all the wires can be inserted into the connection holes of the circuit board at one time, making the perforating process stable and efficient.
