Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5 A car connector with a sealed mating structure includes a male head 1 and a female head 2. Multiple insertion heads 3 are fixedly installed inside the male head 1, and a plug 4 that mates with the multiple insertion heads 3 is fixedly installed inside the female head 2. Two connecting plates 5 are fixedly installed on the outer walls of both the male head 1 and the female head 2. A fixing plate 6 is fixedly installed on the outer wall of each connecting plate 5. A fixing pin 7 is slidably installed through the outer wall of each connecting plate 5. An insertion hole that mates with the fixing pin 7 is opened on the inner wall of each fixing plate 6. A lever 8 is fixedly installed at the end of each fixing pin 7. A fixing spring 9 is installed on the outer wall of each fixing pin 7. Both ends of each fixing spring 9 are elastically connected to the inner wall of the lever 8 and the outer wall of the connecting plate 5, respectively.

[0023] A sealing gasket 10 is fixedly installed on the inner wall of the male connector 1. The sealing gasket 10 is made of rubber and has good elasticity and aging resistance. When the male connector 1 and the female connector 2 are mated, the sealing gasket 10 can undergo elastic deformation, tightly filling the gap and effectively preventing the intrusion of water vapor, dust and other impurities. The inner wall of the female connector 2 has a sealing groove that matches the sealing gasket 10. The opening of the sealing groove is the same size as the sealing gasket 10. The size matching between the sealing groove and the sealing gasket 10 ensures that the sealing gasket 10 can be completely embedded in the groove to form a sealing structure when mated, which greatly improves the sealing performance and meets the protection requirements under the complex working conditions of automobiles.

[0024] A pressing plate 11 is fixedly installed on the outer wall of a connecting plate 5 on the outer wall of the male head 1. A sliding rod 13 is fixedly installed on the outer wall of the male head 1 via a moving frame 12. A moving plate 15 is slidably installed on the outer wall of the sliding rod 13 via a limiting mechanism. The limiting mechanism includes a limiting rod 14 fixedly installed inside the moving frame 12. The limiting rod 14 slides through the moving plate 15. The limiting rod 14 is set parallel to the sliding rod 13. The double guiding structure ensures that the moving plate 15 does not shift or rotate during the sliding process, ensuring that the reset mechanism and the connecting mechanism operate stably and reliably.

[0025] The outer wall of the movable plate 15 is connected to the inner wall of the movable frame 12 through a reset mechanism. The reset mechanism includes a reset spring 16 installed on the outer wall of the slide rod 13. The two ends of the reset spring 16 are elastically connected to the outer wall of the movable plate 15 and the inner wall of the movable frame 12, respectively. The reset spring 16 is in a compressed state when the connector is docked, storing elastic potential energy. When unlocked, it releases energy to push the movable plate 15 to reset. Through the connecting mechanism, it drives the pressing plate 11 to generate a separation thrust, making it easier to separate the male head 1 and the female head 2. The outer wall of the movable plate 15 is connected to the outer wall of the pressing plate 11 through the connecting mechanism. The connecting mechanism includes a connecting rod 17 fixedly installed on the outer wall of the movable plate 15. The end of the connecting rod 17 is fixedly connected to the outer wall of the pressing plate 11. The connecting rod 17 transmits the linear motion of the movable plate 15 to the pressing plate 11, realizing the synchronous action of the pressing plate 11 and the movable plate 15 during the docking process, ensuring that the force of the reset mechanism can effectively act on the separation operation of the male head 1 and the female head 2.

[0026] When using this utility model, when docking the male head 1 and the female head 2, first move the levers 8 on both sides. At this time, the fixing pin 7 slides outward along the connecting plate 5 under the action of the levers 8. The fixing spring 9 is compressed and accumulates elastic potential energy. After the fixing pin 7 is completely removed from the insertion hole range of the fixing plate 6, align the front end of the male head 1 with the docking surface of the female head 2 so that the insertion head 3 inside the male head 1 and the insertion connector 4 inside the female head 2 are precisely aligned. At the same time, ensure that the sealing gasket 10 on the inner wall of the male head 1 and the sealing groove on the inner wall of the female head 2 are on the same axis.

[0027] Then, the male head 1 and female head 2 are slowly pushed closer to each other, and the insertion head 3 is gradually inserted into the connector 4 to form an electrical connection. The rubber sealing gasket 10 is gradually embedded into the sealing groove under the pressure and undergoes elastic deformation, filling the gap between the two to form a preliminary seal. When the male head 1 and female head 2 are completely fitted, the fixing pin 7 on the connecting plate 5 and the insertion hole on the fixing plate 6 are exactly at the same horizontal line. At this time, the lever 8 is released, the fixing spring 9 releases elastic potential energy, pushes the fixing pin 7 to slide inward along the connecting plate 5 and accurately inserts into the corresponding insertion hole, completing the mechanical locking of the male head 1 and female head 2.

[0028] During this process, the pressing plate 11 on the outer wall of the male head 1 pushes the connecting rod 17 synchronously with the docking action, causing the moving plate 15 to slide along the sliding rod 13 and the limiting rod 14 into the moving frame 12. The return spring 16 is compressed. When it is necessary to separate the male head 1 and the female head 2, the toggle block 8 is moved again to make the fixing pin 7 exit the insertion hole. The elastic force of the return spring 16 is transmitted to the pressing plate 11 through the moving plate 15 and the connecting rod 17, generating an auxiliary separation thrust, which makes it easy to separate the two. At the same time, the sealing gasket 10 returns to its original state, ensuring that the sealing effect is not affected during the next docking.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
