[0002] A signal board is a circuit board in electronic equipment. Its main function is to convert various physical input signals into digital signals and convert digital output signals into physical outputs. The design of the signal board aims to simplify operations. It usually has a human-machine dialogue function, is convenient to operate and easy to learn. At the same time, it has a power-off preservation function to ensure that parameters can be stored for a long time.

[0003] The existing patent application number: CN202321120674.6, a PCB connector signal board, includes a substrate. An input area and an output area are provided on the substrate. The input area and the output area are symmetrically arranged along the central axis of the substrate. An indicating mechanism is provided between the input area and the output area. The indicating mechanism is fixedly installed on the substrate. One end of the indicating mechanism is connected to the input area, and the other end is connected to the output area. The indicating mechanism is used to display whether the PCB connector signal board is working properly. The input area and the output area are provided on the substrate, and the input area and the output area are symmetrically arranged along the central axis of the substrate, separating the input area and the output from each other independently, effectively reducing the possibility of incorrect wiring during connection.

[0004] The above patent records a signal board. In the prior art, signal boards often have multiple serial ports extended to meet the needs of connecting multiple external devices. However, when installing and docking the COM interface of the signal board, it needs to be fixed by tightening two screws, which is rather troublesome. When the number of serial ports is large, the installation speed is relatively slow. The serial port installation structure of the signal board can be further improved to improve the installation efficiency. Content of the Utility Model

Specific embodiments

[0018] In order to further explain the technical solution of the present utility model, the following will be elaborated in detail through specific embodiments.

[0019] Please refer to Figure 1 , the present utility model provides a multi - serial - port digital signal board that is easy to install, including a signal board 1, an extension connector 2, a female connector 3, a male connector 4, and a docking installation structure 5. The front - end interface of the signal board 1 is docked and installed with the extension connector 2, the front - end part of the extension connector 2 is wire - connected to the female connector 3, the number of female connectors 3 is not less than 2, the front part of the female connector 3 is docked with the male connector 4, and a docking installation structure 5 is arranged on the surfaces of the female connector 3 and the male connector 4.

[0020] Please refer to Figures 2-4 , the present utility model provides a multi - serial - port digital signal board that is easy to install. The docking installation structure 5 includes a connection groove 51, a flipping frame 52, a torsion spring rotating shaft 53, an overlapping part 54, an overlapping groove 55, and a paddle 56. Connection grooves 51 are symmetrically arranged on the left and right side walls of the female connector 3. A flipping frame 52 is arranged inside the connection groove 51. The cross - section of the flipping frame 52 is concave. Torsion spring rotating shafts 53 are installed at the two ends of the tail of the flipping frame 52. The flipping frame 52 is rotationally connected to the side wall of the connection groove 51 through the torsion spring rotating shaft 53. The flipping frame 52 can be self - flipped and retracted into the connection groove 51 through the elastic force of the torsion spring rotating shaft 53. Overlapping parts 54 are symmetrically arranged on the left and right sides of the front side of the flipping frame 52. The overlapping parts 54 are vertically arranged on the flipping frame 52. Overlapping grooves 55 are symmetrically arranged on the left and right sides of the front side of the male connector 4. When the female connector 3 and the male connector 4 are in the docking state, the overlapping parts 54 can overlap and engage with the inside of the overlapping grooves 55, thereby clamping the position of the male connector 4 and preventing the male connector 4 from loosening and falling off. A paddle 56 is integrally arranged in the middle of the top surface of the flipping frame 52. With the help of the paddle 56, it is more convenient to lift the flipping frame 52 upward and open it.

[0021] Further explanation, the rotation angle range of the flipping frame 52 is not less than 90 degrees, ensuring that the flipping frame 52 has a large enough flipping angle so that the docking operation between the female connector 3 and the male connector 4 will not be affected after the flipping frame 52 is flipped up.

[0022] Further explanation, a rubber pad 541 is adhesively provided at the bottom end of the lapping portion 54. When the lapping portion 54 and the lapping groove 55 are in a clamped state, the rubber pad 541 hooks on the bottom of the lapping groove 55, further enhancing the connection firmness between the lapping portion 54 and the lapping groove 55.

[0023] Further explanation, the longitudinal length of the lapping groove 55 > 8 mm, and the longitudinal lengths of the lapping portion 54 and the lapping groove 55 are the same, so that the lapping portion 54 and the lapping groove 55 have sufficient connection length and are not easily loosened and slipped off.

[0024] Further explanation, anti-slip lines are provided on one side of the lapping portion 54 corresponding to the lapping groove 55, increasing the friction between the lapping portion 54 and the lapping groove 55, and further enhancing the connection firmness.

[0025] The working principle is as follows:

[0026] First, before use, first connect the extension joint 2 with the signal board 1. The extension joint 2 can expand multiple female joints 3 for the signal board 1 to meet the needs of connecting multiple external devices.

[0027] Second, during use, the external device is connected to the female joint 3 through the male joint 4. The specific operation method is as follows: First, use the dial 56 to lift the flipping frame 52 upward and turn it over. Then hold the flipping frame 52 to prevent it from resetting. Then the male joint 4 and the female joint 3 can be docked. After the docking is completed, release the flipping frame 52 to let it rotate and retract into the inner side of the connection groove 51 by the elastic force of the torsion spring rotating shaft 53. During this process, the flipping frame 52 will snap the lapping portion 54 into the inner side of the lapping groove 55 to fix the position of the male joint 4, preventing the male joint 4 from loosening and falling off, thus realizing the installation and fixation of the male joint 4 and the female joint 3. Compared with the existing method of fixing with two screws, it is more convenient and fast, and can effectively improve the installation efficiency.

[0028] Third, when disassembling the male joint 4 and the female joint 3, just lift the flipping frame 52 upward and turn it over, and the male joint 4 can be directly pulled off and detached from the female joint 3. The disassembly operation is also fast.

[0029] The above are only the preferred examples of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
