[0002] A power supply PCB is a type of printed circuit board specifically designed for use in power supply equipment. The main function of a power supply PCB is to provide electrical connections and support for electronic components in the power system, ensuring its normal operation. To facilitate a stable connection between the power supply PCB and the power lines, a connection structure for the power supply PCB is required.
[0003] Traditional connection structures for power PCBs typically involve directly connecting the power cord to the power interface on the PCB to supply power. However, traditional power cord connections require a tight fit, making it difficult to easily remove the power cord after the PCB is mounted and fixed, thus affecting device usability. Furthermore, during the installation process, it is difficult to ensure a stable connection between the power cord and the interface. Utility Model Content
[0004] In view of the shortcomings of the prior art, this utility model provides a connection structure for power supply PCBs to solve the problems mentioned in the background art.
[0005] This utility model provides the following technical solution: a connection structure for a power PCB, including a PCB board body, a power interface fixedly mounted on the PCB board body, a power wire slidably connected to the inner wall of the power interface, a groove opened on the side of the power wire, a protrusion slidably sleeved on the inner wall of the groove, a cylinder fixedly mounted on the side of the power interface, and the inner wall of the cylinder slidably sleeved with the outer edge of the protrusion, a fixing cylinder fixedly mounted on the side of the power interface, and the side of the inner wall of the fixing cylinder fixedly mounted with the side of the cylinder, a sliding groove opened on the side of the power interface, and a limit groove opened on the side of the inner wall of the sliding groove.
[0006] As a preferred embodiment of this utility model, a round rod is fixedly mounted on the side of the protruding rod, and the outer edge of the round rod is slidably sleeved with the inner wall of the fixed cylinder. A spring is fixedly connected to the side of the protruding rod, and the end of the spring away from the protruding rod is fixedly connected to the side of the inner wall of the fixed cylinder. A fixing plate is fixedly mounted on the side of the round rod.
[0007] As a preferred embodiment of this utility model, the inner wall of the limiting groove is rotatably connected to a limiting plate, and a sliding rod is fixedly mounted on the side of the limiting plate. The outer edge of the sliding rod is slidably sleeved with the inner wall of the fixed cylinder, and the outer edge of the sliding rod is rotatably sleeved with the inner wall of the fixed plate.
[0008] As a preferred embodiment of this utility model, a pull rod is fixedly mounted on the side of the slide rod, and a pull plate is fixedly mounted on the side of the pull rod.
[0009] As a preferred technical solution of this utility model, a protrusion is fixedly assembled on the side of the inner wall of the limiting groove, and a slot is opened on the side of the limiting plate, and the shape and size of the inner wall of the slot are completely consistent with the shape and size of the outer edge of the protrusion.
[0010] As a preferred technical solution of this utility model, the number of grooves is four, and the inner walls of the four grooves are slidably fitted with four protrusions. The connection structure of the outer edges of the four protrusions is completely identical. The number of protrusions is two, and the two protrusions are on the inner walls of the limiting grooves on the side away from the power interface and close to both ends.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] 1. This connection structure for power PCB uses the cooperation of groove and protrusion. The pull plate drives the limit plate to rotate through the pull rod and slide rod. Then, the pull rod is moved away from the power interface until the outer edge of the pull rod separates from the inner wall of the slide groove. At this time, the power wire is moved away from the power interface, thereby using the inner wall of the groove to push the protrusion to the inner wall of the fixed cylinder, which facilitates the quick disassembly of the power wire and the PCB board body.
[0013] 2. This connection structure for power supply PCBs utilizes the cooperation of a limiting groove and a protrusion. A limiting plate rotates within the inner wall of the limiting groove, assisting in the alignment and positioning of the inner wall of the groove with the outer edge of the protrusion. The limiting plate, through a fixing plate, drives a round rod to be positioned within the inner wall of a cylinder. This round rod then drives the outer edge of the protrusion to be positioned within the inner wall of the groove. The protrusion further assists in the positioning of the power wiring, thus facilitating convenient power wiring and interface connection while ensuring the stability of the power wiring and interface connection.

A fixing plate 10 is fixedly mounted on the side of the round rod 9. Through the cooperation of the spring 8 and the protruding rod 5, the spring 8 pushes the protruding rod 5 in the inner wall of the fixed cylinder 6, thereby assisting the outer edge of the protruding rod 5 to stably connect with the inner wall of the groove 4.
[0025] In a preferred embodiment, a limiting plate 17 is rotatably connected to the inner wall of the limiting groove 15. A sliding rod 13 is fixedly mounted on the side of the limiting plate 17, and the outer edge of the sliding rod 13 is slidably sleeved with the inner wall of the fixed cylinder 6. The outer edge of the sliding rod 13 is rotatably sleeved with the inner wall of the fixed plate 10. Through the cooperation of the limiting plate 17 and the limiting groove 15, the inner wall of the limiting groove 15 is in two arc shapes. Then, the outer edge of the limiting plate 17 passes through the inner wall of the sliding groove 14 to the inner wall of the limiting groove 15. Then, the limiting plate 17 is rotated, thereby using the side of the inner wall of the limiting groove 15 to assist in limiting the limiting plate 17.
[0026] In a preferred embodiment, a pull rod 12 is fixedly mounted on the side of the slide rod 13, and a pull plate 11 is fixedly mounted on the side of the pull rod 12. Through the cooperation of the pull rod 12 and the pull plate 11, the pull plate 11 drives the slide rod 13 to move through the pull rod 12, and then the slide rod 13 drives the limiting plate 17 to perform convenient position adjustment.
[0027] In a preferred embodiment, a protrusion 16 is fixedly mounted on the side of the inner wall of the limiting groove 15, and a slot 18 is opened on the side of the limiting plate 17.

[0029] Working principle: When the device is in use, the pull plate 11 drives the limiting plate 17 to rotate through the pull rod 12 and the slide rod 13. Then, the pull rod 12 is moved away from the power interface 3 until the outer edge of the pull rod 12 separates from the inner wall of the slide groove 14. At this time, the power cable 2 is moved away from the power interface 3, thereby using the inner wall of the groove 4 to push the protrusion 5 to move to the inner wall of the fixed cylinder 6, which facilitates the quick disassembly of the power cable 2 and the PCB board body 1. The limiting plate 17 is rotated in the inner wall of the limiting groove 15, thereby assisting the inner wall of the groove 18 to align and limit the outer edge of the protrusion 16. Then, the limiting plate 17 drives the round rod 9 to be limited in the inner wall of the cylinder 7 through the fixed plate 10. Then, the round rod 9 drives the outer edge of the protrusion 5 to be limited in the inner wall of the groove 4. Then, the protrusion 5 assists in limiting the power cable 2, thereby facilitating the connection between the power cable 2 and the power interface 3 while ensuring the stability of the connection between the power cable 2 and the power interface 3.
