Description

Technical Field

[0001] The utility model relates to the field of PCB circuit boards, and in particular to a PCB circuit board that does not require punching. Background Art

[0002] Printed circuit board (PCB), also known as printed circuit board, is the provider of electrical connections for electronic components. It has a history of more than 100 years, and its design is mainly layout design. The main advantage of using circuit boards is that it greatly reduces wiring and assembly errors, improves the level of automation and production labor rate. According to the number of layers of the circuit board, it can be divided into single-sided board, double-sided board, four-layer board, six-layer board and other multi-layer circuit boards. As the core of control, PCB circuit boards have a wide range of applications. Some are installed in static control boxes, and some are installed on electronic devices that are susceptible to vibration, such as laptop motherboards, control panels inside cars, etc. The existing PCB circuit boards are easily damaged during use due to their own material and the need to be punched and fixed, which makes the PCB circuit boards unable to be used later, resulting in low efficiency in the production and use of PCB circuit boards.

[0003] The Chinese utility model patent application number 202021070125.9 proposes a PCB circuit board, but it is found that there are still some shortcomings in its use:

[0004] First, the screw rod blocks the circuit board body, so the circuit board body can only be inserted from the space before the screw rod in the front and back direction, and must be fixed in the last step after the filter and the carrier are fixed, which is inconvenient to install. When replacing the circuit board body, the filter and the carrier must be completely removed before the circuit board body can be taken out, which is very inconvenient to operate;

[0005] Second, the top structure of the adjusting bolt does not allow for manual rotation, which means that tools are required to disassemble the circuit board body, which is not convenient enough;

[0006] 3. The filter is fixed by four bolts and cannot be quickly disassembled and assembled by hand, which needs to be optimized.

[0007] Based on this, the utility model proposes a PCB circuit board that does not require punching to solve the above problems. Utility Model Content

[0008] In order to overcome the defects in the above-mentioned prior art, the utility model provides a PCB circuit board that does not require punching. By arranging the positions of limit columns and stop columns, the circuit board body can be directly inserted and installed from the front side, so that the circuit board body is not restricted by other components during loading and unloading, and the circuit board body can be directly loaded and unloaded, which facilitates the separate replacement of the circuit board body. Through the provision of a rotating arm and a rotating pressure block, the circuit board body and the filter screen can be quickly disassembled and assembled by hand, which is very convenient.

DETAILED DESCRIPTION

[0026] In order to better illustrate the content of the utility model, the following is a description with reference to the accompanying drawings and implementation examples:

[0027] have Figure 1-Figure 4 As shown, the utility model discloses a PCB circuit board that does not require punching, including two symmetrically positioned support plates 5, the support plates 5 are provided with fixing bolts 6, the support plates 5 are fixedly provided with pillars 10, the upper ends of the pillars 10 are fixedly provided with a top plate 2, the upper surface of the top plate 2 is provided with a filter screen mechanism 901 that can be quickly loaded and unloaded, a circuit board body 1 is placed on the support plates 5, and a clamping structure 902 that can directly and quickly load and unload the circuit board body 1 is provided between the top plate 2 and the support plates 5.

[0028] Furthermore, a notch 17 is cut at the front and rear ends of a side surface close to each other of the pillar 10 .

[0029] Furthermore, the clamping structure 902 includes a pressure plate 4 located between the support plate 5 and the top plate 2 and abutting against and slidably connected to the support column 10, and an upper end of the pressure plate 4 is fixedly connected to an adjusting bolt 9 via a bearing, and the adjusting bolt 9 passes through and is threadedly connected to the top plate 2.

[0030] Furthermore, a limiting column 11 is provided at the position of the notch 17 and is fixed between the top plate 2 and the support plate 5 and passes through and is slidably connected to the pressure plate 4. The rear side of the pressure plate 4 is also penetrated by a blocking column 8 fixed on the support plate 5 for limiting the circuit board body 1.

[0031] Furthermore, a rotating arm 14 is fixedly connected to the upper end of the adjusting bolt 9, and a fixing bolt 13 is passed through and threadedly connected to the end of the rotating arm 14 away from the adjusting bolt 9, and a socket 15 is provided in the upper end surface of the top plate 2, into which the fixing bolt 13 can be inserted and which limits the rotation of the rotating arm 14.

[0032] Furthermore, the filter mechanism 901 includes a groove 16 disposed in the upper surface of the top plate 2 , in which the filter plate 7 is placed, and a rotating pressing block 12 for pressing the filter plate 7 is rotatably disposed on the top plate 2 .

[0033] Furthermore, the angle between the bevel surface on the upper surface of the filter screen plate 7 and the horizontal plane is greater than the angle between the lower bevel surface of the rotary pressing block 12 and the horizontal plane, so that the rotary pressing block 12 can press the filter screen plate 7 tightly.

[0034] Furthermore, a deformable pressure pad 3 is provided on the lower surface of the pressure plate 4 , so that the downward displacement of the pressure plate 4 is an interval value, so that the fixing bolt 13 can always be inserted into the insertion hole 15 .

[0035] Specifically, when in use, first fix the carrier plate 5 by fixing the bolts 6, and then you can choose to fix the circuit board body 1 or the filter screen plate 7;

[0036] When fixing the circuit board body 1, the circuit board body 1 can be inserted from the front side between the pressing plate 4 and the supporting plate 5.
