[0002] A pin header, also known as a pin header socket or connector socket, is an interface component used to connect electronic components on a circuit board. It typically consists of an insulated plastic base and metal pins, providing pluggable electrical connections and facilitating the interface between the PCB and other modules, cables, or external devices.

[0003] Existing pin headers, such as the card pin header connector proposed in patent application number "CN202222209453.8", include a connector body and pins fixed on the connector body. The connector body is provided with a connecting part extending in the same direction as the insertion direction of the pins. After the connecting part is connected to the circuit board, the connector body and the circuit board can be relatively fixedly fitted, and the connector body is inserted and installed on the upper end of the surface of the circuit board.

[0004] However, existing technologies have drawbacks. The pin holder protrudes from the PCB board surface, and the overall structure formed by the pin holder and the PCB board is relatively thick, which is not conducive to the design of thin and light electronic devices. Therefore, a recessed pin holder is proposed. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] A type of recessed pin seat, such as Figures 1-6 As shown, the base 2 of the pin holder is recessed and installed in the mounting port 11. The thickness formed by the pin holder and the PCB board 1 is the thickness of the pin holder, which is thinner than the thickness of the prior art. The base 2 is soldered to the PCB board 1 by a soldering assembly. The pin 4 plays a role in signal transmission. The entire pin holder is embedded in the PCB board 1, forming a recessed plate structure (the bottom of the base 2 is recessed into the PCB board 1), reducing the height of the protrusion 5, which is suitable for ultra-thin electronic devices.

[0030] The base plate assembly is inserted into the bottom of the base 2, and the base plate assembly is snapped into the base 2 to prevent it from falling off. The base plate assembly is inserted into the bottom of the PCB board 1. There is space between the base plate assembly and the pin 4, so that the PCB board 1 is inserted into this space. The base plate assembly and the pin 4 abut against the PCB board 1 from both the top and bottom, forming a multi-point fixation. With the help of the welding assembly, the pin holder is effectively prevented from loosening.

[0031] When the base plate assembly is inserted, the extension plate 18 is inserted into the lower end of the base 2, the lower insertion plate 16 is connected to the socket 12, and the upper insertion plate 17 is connected to the limiting port 13. The base plate assembly is pushed into the base 2, so that the upper insertion plate 17 and the lower insertion plate 16 are respectively inserted into the limiting port 13 and the socket 12. The width of the upper insertion plate 17 is greater than that of the lower insertion plate 16 to prevent the base plate assembly from detaching from the base 2. The extension plate 18 is inserted from the lower end of the base 2 to the back of the base 2 and slides against the lower end of the PCB board 1. It cooperates with the pin 4. The base 2 is located in the mounting port 11. The PCB board 1 is inserted between the pin 4 and the extension plate 18 to increase the installation stability of the pin holder.

[0032] The side wall of the insertion port 12 has a rectangular opening 14, and a retaining plate 15 is fixedly connected inside the rectangular opening 14. The side wall of the lower insertion plate 16 has a retaining slot 19, which is mated with the rectangular opening 14, and the retaining plate 15 is engaged with the retaining slot 19.

[0033] When the base plate assembly is installed, the lower insert plate 16 presses the clamping plate 15 until the rectangular opening 14 aligns with the bayonet 19. The clamping plate 15 then returns to its original shape and snaps into the bayonet 19. The end of the clamping plate 15 abuts against the inner wall of the bayonet 19 to prevent the base plate assembly from detaching from the base 2.

[0034] The design of the locking plate 15 and the locking slot 19 further locks the base plate assembly, ensuring the stability of the base plate assembly for long-term use.

[0035] The solder pad 8 is inserted into the slot 7 of the base 2. The bent ends of the solder pad 8 are in close contact with the upper and lower ends of the base 2, and the solder pad 8 and the PCB board 1 are soldered together, thereby fixing the base 2 on the PCB board 1. The soldering is more secure. The protrusion 9 on the solder pad 8 makes the solder pad 8 more securely installed in the base 2 and prevents it from falling off.

[0036] Both the protrusion 5 and the groove 6 are wavy. One end of the pin 4 is inserted into the pin hole 3. When inserted, the protrusion 5 and the groove 6 are engaged, which increases the firmness of the connection between the pin 4 and the pin hole 3.

[0037] The working principle of the recessed pin seat provided by this utility model is as follows:

[0038] The base plate assembly is inserted into the bottom of the PCB board 1. There is space between the base plate assembly and the pin 4, allowing the PCB board 1 to be inserted into this space. The base plate assembly and the pin 4 abut against the PCB board 1 from both the top and bottom, forming a multi-point fixation. With the help of the soldering assembly, the pin holder is effectively prevented from loosening. The base 2 of the pin holder is recessed and installed in the mounting port 11, forming a recessed plate structure. The thickness formed by the pin holder and the PCB board 1 is the thickness of the pin holder, reducing the height of the pin holder protrusion 5, which is suitable for ultra-thin electronic devices.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
