DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4The utility model provides a technical solution: a plug-in connector with an anti-pull structure, comprising a male plug 1 and a female plug 2, a fixing block 3 is installed on one side outer wall of the male plug 1, a limiting groove 301 is arranged inside the fixing block 3, a limiting block 4 is fixedly installed on one side outer wall of the female plug 2, one end of the limiting block 4 is connected to the inner limit of the limiting groove 301, a wiring harness 8 is sleeved on one end of the male plug 1, one end of the wiring harness 8 and one end of the male plug 1 are provided with an anti-pull component, the anti-pull component comprises an anti-pull cap 6 and an anti-pull cover 7, one end of the anti-pull cap 6 is fixedly connected to one end of the male plug 1, a sealing gasket 12 is placed inside the other end of the anti-pull cap 6, and one end of the anti-pull cover 7 is threadedly connected to the other end of the anti-pull cap 6;

[0023] When in use, the limiting connection between the fixing block 3 on one side of the male plug 1 and the limiting block 4 on the side of the female plug 2 provides a stable mechanical structure for the connector. By rotating the anti-pull cover 7, it can be tightly fitted on the anti-pull cap 6 to form a tight sealing structure, which is not only stable and reliable, but also can effectively prevent external force from invading through the gap between the anti-pull cover 7 and the anti-pull cap 6, further enhancing the stability of the connection between the wiring harness 8 and the male plug 1, and the presence of the sealing gasket 12 can also ensure the waterproof and dustproof performance of the connector, and protect the internal electronic components from the influence of the external environment. Through the design of the anti-pull component, the connection between the wiring harness 8 and the male plug 1 is more stable, and even if it is pulled by external force, it can effectively resist the pulling force to prevent the connection from loosening or disconnecting, thereby ensuring the stable transmission of the signal.

[0024] The sealing gasket 12 is configured as an elastic sealing ring, and a through hole is opened in the center of the sealing gasket 12 for the wiring harness 8 to pass through. The elastic sealing ring has good elasticity and adaptability, and can fit tightly between the male plug 1 and the anti-pull cap 6 to form an effective seal. The through hole opened in the center is specially designed for the wiring harness 8, ensuring that the wiring harness 8 can smoothly pass through the sealing gasket 12 without being obstructed or squeezed.

[0025] A plurality of anti-slip toothed rings 11 are fixedly installed around the other end of the anti-pull cap 6. The plurality of anti-slip toothed rings 11 are sleeved on the side wall of the other end of the anti-pull cap 6 in a circular array. The presence of the anti-slip toothed rings 11 significantly enhances the friction on the surface of the anti-pull cap 6. The increased friction enables the user to grasp and apply force more easily when operating the connector 13, especially when it is necessary to rotate or tighten the anti-pull cap 6 and the anti-pull cover 7, which not only improves the convenience of operation, but also reduces the risk of operational errors due to slippage.

[0026] An external thread 9 is provided on the outer wall of one side of the anti-pull cap 6, and an internal thread 10 is provided on the inner wall of one end of the anti-pull cover 7. A rubber gasket is sleeved on the outer wall of the anti-pull cap 6 on the side close to the external thread 9. The cooperation of the external thread 9 and the internal thread 10 realizes a tight connection between the anti-pull cap 6 and the anti-pull cover 7. The rubber gasket has good elasticity and sealing performance. When the anti-pull cover 7 is tightened, the rubber gasket can fit tightly on the outer wall of the anti-pull cap 6 to form an additional sealing barrier to effectively prevent liquid or gas penetration.

[0027] A clamping block 401 is fixedly installed at one end of the limit block 4, and a clamping slot for placing the clamping block 401 is opened at the inner top of the limit groove 301. The clamping block 401 passes through the interior of the limit groove 301 and is clamped and installed with the clamping slot. Through the clamping connection between the clamping block 401 and the clamping slot, the connection between the limit block 4 and the limit groove 301 is more secure and not easy to loosen or fall off, which can effectively prevent the connector 13 from loosening or separating due to vibration or external force during use, thereby ensuring the stability and durability of the connection.

[0028] A connecting seat 5 is installed at one end of the female plug 2, and a connector plate 17 is installed at the other end of the female plug 2. A protrusion 15 is fixedly installed at the center of the bottom end of the connector plate 17. A groove 16 is opened at the bottom end of the cavity of the male plug 1. The protrusion 15 is slidably connected with the groove 16. The sliding connection between the protrusion 15 and the groove 16 ensures that the female plug 2 and the male plug 1 can be accurately matched when docking, reducing the risk of connection failure caused by misalignment or deviation.

[0029] A connector 13 is fixedly installed inside the male plug 1, and a connector hole 14 is provided on one side of the cavity of the female plug 2. One end of the connector 13 passes through the connector hole 14 and is snap-connected with the connector hole 14. The snap-connection between the connector 13 and the connector hole 14 provides a fastened connection method, so that the male plug 1 and the female plug 2 can form a stable and non-loose connection structure after docking, which can effectively prevent the connection from loosening or falling off due to vibration, impact or external force, thereby ensuring the reliability and stability of the connector 13.
