[0004] Regarding the above-mentioned and existing related technologies, the inventor believes that the following defects often exist: existing connectors are prone to loosening during use, which not only affects the normal connection of the circuit, but may also lead to equipment failure or even safety hazards; therefore, a self-locking connector is proposed to address the above problems. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing connectors are prone to loosening during use, which not only affects the normal connection of the circuit, but may also lead to equipment failure or even safety hazards. Therefore, a self-locking connector is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a self-locking connector, comprising a male connector and a female connector, wherein a fixing block is fixedly connected to both sides of the male connector, and a fixing frame is fixedly connected to both sides of the female connector, wherein a snap-fit ​​groove is formed on the surface of the fixing frame, and a snap-fit ​​plate is fixedly connected to one side of the fixing block, wherein the size of the snap-fit ​​plate is adapted to the size of the snap-fit ​​groove of the fixing frame, and the snap-fit ​​plate is made of a soft material.

[0007] The effects achieved by the above components are as follows: the fixing block and the fixing frame are mechanically locked by the snap-fit ​​plate embedded in the snap-fit ​​groove. The elastic deformation capability of the soft material can compensate for processing errors, ensuring a tight fit during connection and preventing loosening. No additional tools are required; the snap-fit ​​can be completed simply by inserting and removing the male and female connectors. The buffering effect of the soft material can reduce operating resistance, while the material's resilience enables automatic locking, improving assembly efficiency. At the same time, the shock absorption characteristics of the soft material can reduce the impact of external vibrations on the connection structure. The geometric fit between the snap-fit ​​groove and the snap-fit ​​plate further enhances the anti-pull-out capability, making it suitable for reliable connections in dynamic or harsh environments.

[0008] Preferably, a spring is fixedly connected to the inner wall of the snap-fit ​​plate.

[0009] The effect achieved by the above components is that by setting a spring, the rebound ability of the snap-fit ​​plate is enhanced, thereby improving the stability when the male connector and the female connector are connected.

[0011] The aforementioned components achieve the following effect: by rotating the control panel on the U-shaped plate, it is convenient for workers to disassemble and reassemble the male and female connectors, thus improving the practicality of the device.

[0012] Preferably, the arc surface of the rotating rod is fitted with two torsion springs, and the two ends of the torsion springs are fixedly connected to the U-shaped plate and the operating plate, respectively.

[0013] The aforementioned components achieve the following effect: under the force of the torsion spring, the control panel is automatically opened, thus improving the practicality of the device.

[0014] Preferably, a buffer plate is fixedly connected to the surface of the fixing frame, and a buffer pad is fixedly connected to the surface of the buffer plate.

[0015] The effect achieved by the above components is that, through the cooperation of the buffer plate and the buffer pad, the automatic opening control panel is buffered, thereby improving the practicality of the device.

[0016] Preferably, a sealing gasket is fixedly connected to the surface of the female connector, and one side of the sealing gasket abuts against the male connector.

[0017] The effect achieved by the above components is that by setting a sealing gasket, a sealing effect is achieved when the male connector and the female connector are connected, thereby improving the practicality of the device.

[0019] The aforementioned components achieve the following effect: by setting a guide rod, the connection between the male and female connectors is guided, thus improving the practicality of the device.

[0020] In this invention, the fixing block and the fixing frame are mechanically locked by the snap-fit ​​plate embedded in the snap-fit ​​groove. The elastic deformation capability of the soft material can compensate for processing errors, ensuring a tight fit during connection and preventing loosening. No additional tools are required; the snap-fit ​​can be completed simply by inserting and removing the male and female connectors. The buffering effect of the soft material reduces operating resistance, while the material's rebound force enables automatic locking, improving assembly efficiency. In addition, the shock-absorbing properties of the soft material reduce the impact of external vibrations on the connection structure. The geometric compatibility of the snap-fit ​​groove and the snap-fit ​​plate further enhances the anti-pull-out capability, making it suitable for reliable connections in dynamic or harsh environments.

[0027] Reference Figure 1-5As shown, this utility model provides a technical solution: a self-locking connector, including a male connector 1 and a female connector 2. Both sides of the male connector 1 are fixedly connected to a fixing block 3, and both sides of the female connector 2 are fixedly connected to a fixing frame 5. The surface of the fixing frame 5 is provided with a snap-fit ​​groove. A snap-fit ​​plate 4 is fixedly connected to one side of the fixing block 3. The size of the snap-fit ​​plate 4 is adapted to the size of the snap-fit ​​groove of the fixing frame 5. The snap-fit ​​plate 4 is made of a soft material. The fixing block 3 and the fixing frame 5 are mechanically locked by the snap-fit ​​plate 4 embedded in the snap-fit ​​groove. The elastic deformation capability of the soft material can compensate for processing errors, ensuring a tight fit during connection and preventing loosening. No additional tools are required; the snap-fit ​​can be completed simply by inserting and removing the male connector 1 and the female connector 2. The cushioning effect of the soft material reduces operating resistance, and the material's rebound force enables automatic locking, improving assembly efficiency. Furthermore, the shock-absorbing properties of the soft material reduce the impact of external vibrations on the connection structure. The geometric fit between the snap-fit ​​groove and the snap-fit ​​plate 4 further enhances the anti-pull-out capability, making it suitable for reliable connections in dynamic or harsh environments. A spring 6 is fixedly connected to the inner wall of the snap-fit ​​plate 4. By setting the spring 6, the rebound capability of the snap-fit ​​plate 4 is enhanced, improving the stability of the connection between the male connector 1 and the female connector 2. A U-shaped plate 7 is fixedly connected to the surface of the fixing frame 5. A rotating rod 8 is rotatably connected to the inner wall of the U-shaped plate 7. An operating plate 9 is fixedly connected to the arc surface of the rotating rod 8, and an abutment plate 10 is fixedly connected to one side of the operating plate 9. The operation panel 9 is rotated on the U-shaped plate 7, facilitating the disassembly of the male connector 1 and the female connector 2, thus improving the device's practicality. Two torsion springs 11 are fitted onto the arc surface of the rotating rod 8, with both ends of the torsion springs 11 fixedly connected to the U-shaped plate 7 and the operation panel 9, respectively. Under the force of the torsion springs 11, the operation panel 9 is automatically opened, further enhancing the device's practicality. A buffer plate 12 is fixedly connected to the surface of the fixing frame 5, and a buffer pad 13 is fixedly connected to the surface of the buffer plate 12. The cooperation of the buffer plate 12 and the buffer pad 13 buffers the automatically opening operation panel 9, improving the device's practicality. A sealing gasket 17 is fixedly connected to the surface of the female connector 2, with one side of the sealing gasket 17 abutting against the male connector 1. By setting a sealing gasket 17, a sealing effect is achieved when the male connector 1 and the female connector 2 are connected, improving the practicality of the device. A guide rod 14 is fixedly connected to the surface of the male connector 1, and a sleeve 15 is slidably connected to the arc surface of the guide rod 14. The sleeve 15 is fixedly connected to the female connector 2, and a connecting sleeve 16 is fixedly connected to the surface of the female connector 2. The connecting sleeve 16 is slidably connected to the arc surface of the guide rod 14. By setting a guide rod 14, a guiding effect is achieved when the male connector 1 and the female connector 2 are connected, improving the practicality of the device.

[0028] Working principle: The guide rod 14 of the male connector 1 slides along the sleeve plate 15 and the connecting sleeve 16 of the female connector 2, providing axial guidance for the insertion and removal process and ensuring that the plug and socket are aligned. The fixing blocks 3 on both sides of the male connector 1 are inserted into the female connector 2 along with the male connector. The flexible material snap-fit ​​plate 4 on the fixing block 3 is aligned with the snap-fit ​​groove of the female connector fixing bracket 5. Due to the elastic deformation of the flexible material, the snap-fit ​​plate 4 can adapt to the processing error of the snap-fit ​​groove and is smoothly embedded in the groove. After insertion, the snap-fit ​​plate 4 automatically springs open due to the elasticity of its material, tightly fitting against the inner wall of the snap-fit ​​groove to form a mechanical lock, preventing the male and female heads from axially separating. When disassembly is required, manually press the operating plates 9 on both sides to drive the rotating rod 8 to rotate within the U-shaped plate 7. The abutment plate 10 on the operating plate 9 simultaneously squeezes the snap-fit ​​plate 4, causing it to compress the spring 6 and deform inward, disengaging it from the snap-fit ​​groove. After disassembly, the torsion spring 11 on the rotating rod 8 releases its elasticity, pushing the operating plate 9 to automatically return to its initial state. The buffer pad 13 provides a buffering effect on the returned operating plate 9, preventing impact noise or structural damage.
