Description

Technical Field

[0001] The utility model relates to the technical field of PCB boards, in particular to a PCB board with stepped grooves. Background Art

[0002] PCB, also known as printed circuit board, is an important electronic component. It is the support body of electronic components and the carrier for the electrical connection of electronic components. Because it is produced by electronic printing technology, it is called a "printed" circuit board. In some electronic products, the PCB board is made of multi-layer composite boards with stepped grooves inside. At the same time, some PCB boards are not rectangular boards that are easy to process. To save installation space, some products, such as TV products, use L-shaped boards. Currently, PCB board processing is generally designed for rectangular boards. Processing L-shaped boards requires changing equipment design or purchasing new equipment, which will increase cost investment. Therefore, a PCB board with stepped grooves is proposed to address the above problems. Utility Model Content

[0026] The side fixing mechanism 3 includes a clamping plate 301, a fixing screw 302, and a compression pad 303. The fixing screw 302 is rotatably connected to one side of the clamping plate 301.

The compression pad 303 is fixedly connected to the inner side of the clamping plate 301.

[0027] The side of the clamping plate 301 is fixedly connected to an extension plate 304, the outer side of the rear extension plate 304 is fixedly connected to a connecting block 306, the interior of the upper extension plate 304 is spirally connected to a clamping screw 305, and the other end of the clamping screw 305 is spirally connected to the connecting block 306.

[0030] In some electronic products, the PCB boards are made of multi-layer composite boards with stepped grooves opened inside. At the same time, some PCB boards are not rectangular boards that are easy to process. In order to save installation space, some products, such as television products, use L-shaped boards as their internal PCB boards. Currently, PCB board processing is generally designed for rectangular boards. Processing L-shaped boards requires changing equipment design or purchasing new equipment, which will increase cost investment. When the present device is in use, an auxiliary board 2 that matches the PCB board 1 is added. The side surfaces of the auxiliary board 2 cooperate with the auxiliary board 2 through the side fixing mechanism 3 and the central fixing mechanism 5. The clamping plates 301 and the squeezing pads 303 on both sides can be clamped on both sides of the PCB board 1 to fix the PCB board 1. The fixing frame 501 and the buffer plate 503 can be clamped at the connection of the PCB board 1 to fix the PCB board 1. At this time, the PCB board 1 can be ensured to form a rectangle, which facilitates the processing of the PCB board 1 without changing the processing equipment, thereby expanding the scope of application of PCB processing.

[0031] In this embodiment, a blocking block 4 is further provided on one side of the clamping plate 301. The blocking block 4 can prevent the clamping plate 301 from excessive rotation, thereby achieving the purpose of stably fixing the PCB board 1 and ensuring stable processing of the PCB board 1. The provided clamping screw 305 is connected to the connecting block 306, which can further ensure that the clamping plate 301 is close to and fixes the PCB board 1. The setting of the extrusion pad 303 avoids extrusion damage to the extrusion pad 303.

[0032] Example 2: This example is an improvement on Example 1. Figure 3 Specifically, the central fixing mechanism 5 includes a fixing frame 501, a connecting screw 502 and a buffer plate 503. The interior of the fixing frame 501 is fixedly connected to the auxiliary plate 2, and the connecting screw 502 passes through the auxiliary plate 2 and is spirally connected to the fixing frame 501;

[0033] A buffer plate 503 is also fixedly connected to the inner side of the fixing frame 501 .

[0034] The buffer plate 503 is arranged at an angle facing the PCB 1 .

[0035] The auxiliary plate 2 can be recycled, thus avoiding the waste of a large number of PCBs and reducing production costs. In addition, one side of the buffer plate 503 is inclined, which serves as a guide to ensure that the fixing frame 501 is stably fixed to the PCB board 1.

[0036] In this embodiment, the buffer plate 503 on the inner side of the upper and lower plates of the fixing frame 501 is in close contact with the PCB board 1, thereby further fixing the PCB board 1, and the inclined surface of the buffer plate 503 facilitates the stable installation of the central fixing mechanism 5 on the outer side of the PCB board 1.
