Description

Technical Field

[0001] The invention belongs to the technical field of electronic equipment, and in particular relates to a serial port double-sided connection structure. Background Art

[0002] The DB9 connector refers to a 9-core D-type data interface. As a common physical form of RS232 serial interface, it is widely used to connect electronic devices and is a standard interface for electronic devices such as computers and peripherals.

[0003] In practical applications, to facilitate configuration and debugging of serial ports connected to a computer, these ports are often required to be arranged in the same direction for easier management and maintenance. However, under traditional technical architectures, expanding serial ports requires additional space on the motherboard layout to accommodate new connectors and cables. This not only increases the complexity of motherboard design, but also often limits the compactness and miniaturization of devices due to the additional physical space required, reducing the demand for more diverse connections. Summary of the Invention

[0004] In order to solve the problems raised in the above background technology that limit the compactness and miniaturization of devices and reduce the demand for more diversified connections, the present invention provides a serial port double-sided connection structure.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a serial port double-sided connection structure, comprising a PCB board, wherein a solder hole is formed on a surface of the PCB board, a female connector located inside the solder hole is provided on one side of the PCB board, and a male connector located inside the solder hole is provided on the other side of the PCB board, wherein pins are provided on opposite sides of the female connector and the male connector.

[0006] Preferably, a fixing nut is provided on one side of the female connector and the male connector.

[0007] Preferably, a socket is provided on the surface of the PCB board, and buckles located inside the socket are fixedly mounted on opposite sides of the female connector and the male connector.

[0008] Preferably, the number of the fixing nuts is multiple, and each group of two fixing nuts is located on one side of the female head and the male head, and the fixing nuts are designed to be laterally symmetrical about the center of the female head and the male head.

[0009] Preferably, the directions of the female and male connectors can be designed simultaneously, and the selection is made by a program set inside the PCB board.

[0010] Preferably, the PCB board does not require re-circuit design, and the PCB board can be soldered as needed when in use.

[0011] Preferably, the surface of the PCB board can be designed with different types of female connectors and male connectors.

[0012] Preferably, the number of the pins is the same as the number of the solder holes, and the pins on the female connector side are defined in an opposite order to the pins on the male connector side.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The present invention achieves multiple functions at the same location by allowing the female connector to be soldered to one side of the PCB when in use, and the male connector to be soldered to the other side of the PCB when in use. Finally, by simultaneously installing the female and male connectors inside the solder holes, this design cleverly utilizes the mirror-image nature of the male and female connector pin positions, enabling flexible switching between male and female connectors at the same PCB location. This innovation not only greatly enhances the flexibility of the interface, but also effectively increases the number of interfaces without increasing the overall circuit board area, thereby meeting more diverse connection needs.

[0015] The present invention simplifies the production process by reducing the number of holes in the PCB board. In the manufacturing process of electronic devices, drilling holes in the PCB board is a delicate and time-consuming step. Each hole requires precise measurement and positioning to ensure the accurate installation of subsequent components. Therefore, by ensuring that the number of pins and solder holes is the same, the number of holes on the PCB board can be minimized, thereby reducing production costs and improving production efficiency.

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] like Figures 1 to 6 As shown, the present invention provides a serial port double-sided connection structure, including a PCB board 1, a solder hole 2 is opened on the surface of the PCB board 1, a female connector 3 is provided on one side of the PCB board 1 and is located inside the solder hole 2, and a male connector 4 is provided on the other side of the PCB board 1 and is located inside the solder hole 2, and pins 8 are provided on the opposite sides of the female connector 3 and the male connector 4.

[0025] The above solution is adopted: by installing the female connector 3 and the male connector 4 on one side and the other side of the PCB board 1 respectively, and then inserting the pins 8 into the inside of the soldering hole 2 at the same time, taking advantage of the opposite pin positions of the female connector 3 and the male connector 4, the female connector 3 and the male connector 4 can be supported in the same hole position. When the female connector 3 is needed, it can be soldered to one side of the PCB board 1. Conversely, when the male connector 4 is used, it can be soldered to the other side of the PCB board 1. This method reduces the overall area and the number of openings of the PCB board 1. For the female connector 3 and the male connector 4, a group of connection holes are used to realize multiple functions in the same position. In addition, during use, it supports hot plugging function. This means that users do not need to perform the tedious and potentially damaging soldering pin operation every time they connect or disconnect a device. This feature greatly simplifies the device installation and removal process, saving valuable time. Ultimately, by simultaneously installing the female connector 3 and the male connector 4 inside the solder hole 2, this design cleverly utilizes the mirrored characteristics of the male and female pin positions to achieve flexible switching of the male and female connectors on the same PCB board position. This innovation not only greatly improves the flexibility of the interface, but also effectively increases the number of interfaces without increasing the overall area of the circuit board, thereby meeting more diverse connection needs.

[0026] like Figure 1 As shown, a fixing nut 5 is provided on one side of the female connector 3 and the male connector 4 .

[0027] Adopting the above solution: through the design of the fixing nut 5, when the plug is inserted into the female head 3 and the male head 4, the bolt on the surface of the plug can be inserted into the fixing nut 5, and then the plug can be fixed, thereby improving the stability of the equipment operation.

[0028] like Figure 1 、 Figure 2 and Figure 5As shown, a socket 6 is provided on the surface of the PCB board 1, and a clip 7 located inside the socket 6 is fixedly installed on the opposite side of the female connector 3 and the male connector 4. There are multiple fixing nuts 5, and each group of two fixing nuts 5 is located on one side of the female connector 3 and the male connector 4, and the fixing nuts 5 are designed to be laterally symmetrical about the center of the female connector 3 and the male connector 4.

[0029] Adopting the above scheme: through the design of the socket 6 and the buckle 7, when installing the female head 3 and the male head 4, the buckle 7 can be inserted into the inside of the socket 6. When the welding method is not used, the buckle 7 can be stuck in the inside of the socket 6, so that the female head 3 and the male head 4 can be fixed. Through the design of the fixing nut 5, since the fixing nuts 5 are grouped in two and are symmetrically designed, two bolts can be inserted into the inside of the fixing nut 5 at the same time, thereby increasing its fixing effect.

[0030] like Figure 6 As shown, the directions of the female connector 3 and the male connector 4 can be designed at the same time, and the PCB board 1 is internally set up for selection. The PCB board 1 does not need to be re-circuited, and the PCB board 1 can be soldered as needed when in use.

[0031] The above solution is adopted: through the design of the female connector 3 and the male connector 4, since the directions of the female connector 3 and the male connector 4 can be designed at the same time, the PCB board 1 can not only provide a traditional forward interface connection, but also provide a reverse interface connection, thereby greatly expanding the possibility and flexibility of connection. Through the design of the PCB board 1, there is no need to carry out tedious and time-consuming re-circuiting of the PCB board 1. This means that in the initial stage, the basic design of the PCB board 1 can be completed in one go according to the overall layout and functional requirements of the equipment, thereby increasing the convenience of use. Prior to this, the PCB board 1 needs to be wired, and therefore the directions of the female connector 3 and the male connector 4 also need to be determined before use.

[0032] like Figure 1 、 Figure 2 and Figure 3 As shown, the surface of the PCB board 1 can be designed with different types of female connectors 3 and male connectors 4, the number of pins 8 is the same as the number of solder holes 2, and the definition order of the pins 8 on the female connector 3 side is opposite to that of the pins 8 on the male connector 4 side.

[0033] Adopt the above scheme: through the design of PCB board 1, as long as they have the characteristics of female connector 3 and male connector 4, flexible switching and two-way docking can be achieved through this design, which provides great convenience for users. They do not need to worry about interface incompatibility. Through the design of pin 8, since the pin definition order of female connector 3 and male connector 4 is opposite, this design avoids possible errors during the connection process. Since the pin order of female connector 3 and male connector 4 is different, they can only be inserted and fixed if they correspond correctly, thereby effectively preventing connection failure or damage caused by pin misalignment.

[0034] The working principle and use process of the present invention:

[0035] By installing the female connector 3 and the male connector 4 on one side and the other side of the PCB board 1 respectively, and then inserting the pins 8 into the inside of the solder hole 2 at the same time, and the buckle 7 into the inside of the socket 6, the female connector 3 and the male connector 4 are fixed to the surface of the PCB board 1. Then, the opposite position of the pins of the female connector 3 and the male connector 4 is utilized;

[0036] In the first embodiment, when only connecting to the male connector 4, the connector can be inserted into the male connector 4 and then soldered to one side of the PCB board 1;

[0037] In the second embodiment, when connecting only to the female connector 3, the connector can be inserted into the surface of the female connector 3 and then soldered to one side of the PCB board 1;

[0038] In the third embodiment, when the male connector 4 and the female connector 3 need to be connected at the same time, the connectors can be respectively inserted into the male connector 4 and the female connector 3, and then they can be soldered to the PCB board 1 at the same time. That is to say, a single connector is set on the front side, a single connector is set on the back side, and connectors are set on both the front and back sides at the same time, thereby realizing multiple connection methods of the connector, with the characteristics of flexible adjustment, which greatly expands the possibility and flexibility of connection.
