[0002] As the core component of the automotive electronic system, automotive connectors play a key role in ensuring efficient and stable connections between various electronic devices and systems inside the vehicle. With the rapid development of the automotive industry and the significant improvement in the level of electronics, coupled with the continuous improvement of consumers' requirements for automotive safety, environmental protection, comfort and intelligence, the application scope of automotive electronic products has been increasingly broadened, and the importance of automotive connectors has also risen accordingly.

[0003] In the prior art, a typical vehicle connector design includes an insulating base, a plurality of connection terminals firmly mounted on the base, and an insulating shell fixedly arranged around the connection terminals. The external plug is connected by plugging with the connection terminals, and the plug housing and the insulating shell are fixed by snapping to ensure the stability of the connection.

[0004] However, in actual applications, the connector is used on the chassis of the vehicle, and in complex environments such as splashing and wading that may be encountered during the driving of the car, it poses a severe challenge to the waterproof performance of the connector. Since there are often gaps at the plug-in point after the external plug and the connector are plugged in, these gaps can easily become channels for water accumulation or rainwater to penetrate. Once water penetrates into the connector, it may not only cause a short circuit in the connection and affect the normal operation of the electronic equipment, but in serious cases, it may even cause safety hazards such as vehicle loss of control. The consequences are unimaginable, and there is room for improvement. Summary of the invention

[0005] The purpose of this application is to provide a waterproof connector for a vehicle to solve the problem that the waterproof performance of the above-mentioned related art connectors is insufficient and there are safety hazards.

[0048] Reference Figure 4 and Figure 5 , positioning rods 24 are fixedly provided on the sides of the upper protective plate 2 and the lower protective plate 3 that are away from each other, a first magnetic block 25 is embedded on the outer periphery of the positioning rod 24, and second magnetic blocks 14 are embedded on the two opposite sides of the outer periphery of the substrate 1, and the first magnetic block 25 on the positioning rod 24 can rotate with the upper protective plate 2 or the lower protective plate 3 to a state of magnetically abutting with the second magnetic block 14;

[0049] When the external plug is plugged into the connector, the upper protection plate 2 and the lower protection plate 3 can be rotated away from each other, so that the first magnetic block 25 on the positioning rod 24 is magnetically abutted against the corresponding second magnetic block 14 .

[0052] Reference Figure 6 The limiting member 5 includes a compression spring 51 and a limiting block 52, wherein a positioning block 53 is fixedly provided on the side of the limiting block 52, and a receiving groove 16 for the compression spring 51 and the limiting block 52 is provided on the substrate 1, and a limiting hole 152 communicating with the receiving groove 16 is provided on the inner wall of the limiting sink 151; the compression spring 51 presses one side of the limiting block 52 so that the positioning block 53 is inserted into and passes through the protruding limiting hole 152, and a positioning groove 42 for inserting the protruding portion of the positioning block 53 is provided on the cover plate 4;

[0053] Under the pressure of the compression spring 51, the protruding part of the limit block 52 is inserted into the positioning groove 42 on the cover plate 4, thereby locking the cover plate 4 and preventing the cover plate 4 from opening in a natural state; and a control component 6 is provided on the positioning rod 24 to enable the positioning protrusion to escape from the positioning groove 42.

A control port 161 communicating with the receiving groove 16 is provided on the outer surface of the substrate 1, and a guide slope 521 is provided on the outer peripheral edge of the limit block 52 close to the positioning block 53;

[0055] The control block 62 can be inserted into the control port 161 and the storage groove 16 in sequence as the positioning rod 24 rotates. The control block 62 can squeeze the positioning block 53 along the guide slope 521 to make it slide toward the direction close to the compression spring 51, thereby making the protruding part of the positioning block 53 disengage from the positioning groove 42, thereby releasing the lock on the cover plate 4.

[0058] In other embodiments, the connection mode between the positioning rod 24 and the corresponding protective plate can also be set to be hinged, and the upper protective cover 21 and the lower protective cover 31 rotate towards each other. When the external sealing cover 13 and the external plug shell are connected to perform sealing protection, the positioning rod 24 can be rotated 90 degrees and adjusted to a state of abutting against the outer surface of the corresponding protective plate.

[0061] When the external plug is plugged into the connector, the positioning rod 24 and the control rod 61 are adjusted to a coaxial state in advance, and then the upper protective plate 2 and the lower protective plate 3 are rotated away from each other, so that the first magnetic block 25 on the positioning rod 24 is magnetically abutted against the corresponding second magnetic block 14, and the fixing protrusion 18 is inserted into the fixing groove 621 on the control block 62;
