[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model;
[0021] Refer to Figures 1-3, A circuit board with stable connection, including a mounting plate 1 and a circuit board body 2. Connecting blocks 3 are respectively installed on both sides of the mounting plate 1. The circuit board body 2 is arranged between the two connecting blocks 3. A slider 7 is slidably installed on the inner bottom surface of the connecting block 3. A spring rod 11 and a support plate 12 are installed at the center of the mounting plate 1.
[0022] Both of the two connecting blocks 3 are in a U shape, and the opening directions of the two connecting blocks 3 are opposite. Mounting grooves 8 are formed on the inner bottom surfaces of the two connecting blocks 3. The mounting grooves 8 penetrate downward through the bottom of the connecting blocks 3 and extend to the upper surface of the mounting plate 1.
[0023] A plurality of springs 9 are fixedly installed on the inner bottom surface of the mounting groove 8. The ends of the plurality of springs 9 are fixedly connected to the lower surface of the slider 7. The slider 7 is slidably connected to the inner surface of the mounting groove 8. A limiting plate 6 is fixedly installed on the upper surface of the slider 7. The width of the limiting plate 6 is greater than the width of the mounting groove 8. When the springs 9 receive an external impact, they drive the entire slider 7 to move up and down, avoiding the edge of the circuit board body 2 from being broken.
[0024] A plurality of through grooves 5 are formed on the top of the connecting block 3. A plurality of sliding grooves 13 are respectively formed on both sides of the upper surface of the circuit board body 2. The inner diameters of the through grooves 5 and the sliding grooves 13 are the same, and the plurality of through grooves 5 and the sliding grooves 13 correspond to each other one by one. A positioning rod 4 is threadedly connected in the through groove 5. The positioning rod 4 penetrates downward through the lower sliding groove 13 and is slidably connected to the inner surface of the sliding groove 13. A groove corresponding to the positioning rod 4 is formed on the upper surface of the limiting plate 6.
[0025] Push the circuit board body 2 into the lower gap between the two connecting blocks 3 so that the circuit board body 2 is in contact with the upper surface of the limiting plate 6. Screw the positioning rod 4 into the through groove 5 and make it penetrate through the sliding groove 13 of the circuit board body 2 to limit the circuit board body 2.
[0026] The circuit board body 2 is slidably connected to the inner surfaces of the two connecting blocks 3. The thickness of the circuit board body 2 is less than the height inside the connecting block 3.
[0027] A reserved groove 10 is formed at the center of the upper surface of the mounting plate 1. The spring rod 11 is fixedly installed on the inner bottom surface of the reserved groove 10. The support plate 12 is fixedly installed at the end of the spring rod 11, and the upper surface of the support plate 12 is in contact with the lower surface of the circuit board body 2. When the circuit board is subjected to an external impact, the spring rod 11 provides central support for the central vulnerable part of the circuit board body 2 to avoid the circuit board body 2 from being broken.
[0028] Working principle: For this circuit board with stable connection, during use, the circuit board body 2 is pushed into the lower gap between the two connecting blocks 3 so that the circuit board body 2 fits against the upper surface of the limiting plate 6. The positioning rod 4 is screwed into the through groove 5 and passes through the sliding groove 13 of the circuit board body 2 to limit the circuit board body 2. When receiving an external impact, the spring 9 drives the slider 7 to move up and down as a whole to prevent the edge of the circuit board body 2 from cracking. The upper surface of the support plate 12 contacts the lower surface of the circuit board body 2. When the circuit board receives an external impact, the spring rod 11 provides central support for the central vulnerable part of the circuit board body 2 to prevent the circuit board body 2 from cracking.
