[0017] Figure 1 This is a perspective view of the present invention; Figure 2 This is a perspective view of the present invention from another angle; Figure 3 This is an assembly drawing of the housing of this utility model; Figure 4 This is a three-dimensional view of the present invention from a third perspective. Detailed Implementation

[0018] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0019] See Figure 1-4 As shown, a waterproof TYPE-C connector includes an insulating base 1, a terminal 2, a metal inner shell 3, an outer metal shell 4, and a waterproof ring 5.

[0020] The terminals 2 are disposed on the insulating base 1; wherein there are multiple terminals 2, which are arranged in two rows on the insulating base 1; the metal inner shell 3 is fixedly covered around the insulating base 1, and a slot 30 is formed between the metal inner shell 3 and the insulating base 1; the outer metal shell 4 is fixed to the outside of the metal inner shell 3. The waterproof ring 5 is provided at the front end of the metal inner shell 3.

[0021] The main improvement of this utility model is to the waterproof ring 5. Specifically, the waterproof ring 5 integrally wraps the outer surface, front face and inner surface of the front end of the metal inner shell 3. The outer surface of the waterproof ring 5 is formed with a first sealing rib 501. The inner surface of the waterproof ring 5 is formed with a mating opening 50 corresponding to the mating slot 30. The inner surface of the waterproof ring 5 is also formed with a second sealing rib 502. The second sealing rib 502 protrudes from the inner wall of the mating slot 30 and is used to make a sealing contact with the plug connector inserted into the mating slot 30. In other words, after the front end of the waterproof TYPE-C connector of this utility model is inserted into the countersunk hole 61 of the housing 6, the waterproof ring 5 is placed in the countersunk hole 61, and the first sealing rib 501 of the waterproof ring 5 is squeezed and deformed, so that the outer periphery of the front end of the metal inner shell 3 forms a sealed assembly with the countersunk hole 61, realizing the dustproof and waterproof function; at the same time, the inner surface of the waterproof ring 5 is formed with a second sealing rib 502, which protrudes from the inner wall of the slot 30 and is used to make a sealing contact with the plug connector inserted into the slot 30, thereby achieving a sealed waterproof, so as to meet the use of some scenarios with high waterproof performance requirements, which is extremely convenient to use and helps to improve the product's market competitiveness.

[0022] Furthermore, since the waterproof ring 5 is integrally wrapped around the outer surface, front face, and inner surface of the front end of the metal inner shell 3, its structure is extremely stable. Moreover, the waterproof ring 5 will not fold during the insertion of the countersunk hole 61, ensuring the stability and sealing of the assembly. At the same time, the waterproof ring 5 is not easy to detach from the metal inner shell 3, ensuring the service life of the product.

[0023] The front end of the metal inner shell 3 has a flange 31 formed by flipping from the inside out. The waterproof ring 5 is integrally fixed to the front end of the metal inner shell 3 by injection molding and wraps around the flange 31. The flange 31 can provide forward blocking force for the waterproof ring 5, preventing the waterproof ring 5 from moving backward, increasing the contact area between the metal inner shell 3 and the waterproof ring 5, and making its structure more stable. That is, during the process of inserting the waterproof ring 5 into the countersunk hole 61, the flange 31 can provide support force for the waterproof ring 5, preventing the waterproof ring 5 from moving backward, so that the waterproof ring 5 can be smoothly and stably inserted into the countersunk hole 61. During the process of pulling the metal inner shell 3 out of the countersunk hole 61, the flange 31 can stably pull the waterproof ring 5, thereby pulling the waterproof ring 5 out of the countersunk hole 61 without causing the waterproof ring 5 to detach from the metal inner shell 3, thus ensuring the service life of the product.

[0024] The waterproof ring 5 includes an outer sealing part 51 fixedly wrapped around the outer surface of the front end of the metal inner shell 3, a front sealing part 52 integrally connected to the front end of the outer sealing part 51 and formed at the front end face of the metal inner shell 3, and an inner sealing part 53 integrally connected to the lower side of the front sealing part 52 and attached to the inner side of the metal inner shell 3. The outer surface of the outer sealing part 51 is formed with the first sealing rib 501, and the inner side of the inner sealing part 53 is formed with the second sealing rib 502. The inner side of the inner sealing part 53 protrudes from or is flush with the inner wall of the slot 30, which can better enable the second sealing rib 502 to form a better sealing assembly with the plug connector inserted into the slot 30.

[0025] The outer metal shell 4 covers the upper surface and two sides of the inner metal shell 3, and the outer metal shell 4 and the upper surface and two sides of the inner metal shell 3 are fixed by laser welding. Its structure is stable, of higher quality and has a long service life.

[0026] The insulating base 1 has an extension base 11 formed rearward from its rear end. The pin 21 of the terminal 2 is exposed on the lower end face of the extension base 11. The outer metal shell 4 also covers the rear end face of the insulating base 1, the upper end face and the rear end face of the extension base 11, as well as the two sides of the extension base 11, which achieves better shielding against noise affecting the normal operation of this utility model, that is, shielding against noise so that the noise will not affect the signal transmission of this utility model.

[0027] The outer metal shell 4 has a rear shielding plate 41 formed by bending downwards at its upper rear end to cover the rear end face of the insulating base 1. The rear shielding plate 41 is bent upwards to form an upper shielding plate 42 that covers the upper end face of the extension base 11. The rear end of the upper shielding plate 42 is further bent downwards to form a shielding rear plate 43 that covers the rear end face of the extension base 11. Both rear ends of the outer metal shell 4 have shielding side plates 44 formed rearwards to cover the two sides of the extension base 11, thus achieving a fully enclosed structure except for the lower end face of the extension base 11, which has excellent noise shielding effect. The lower end of the outer metal shell 4 has a first solder foot 45 for PCB board soldering and fixing, and the lower end of the shielding side plate 44 has a second solder foot 46 for PCB board soldering and fixing. The first solder foot 45 and the second solder foot 46 are both used for soldering and fixing to the PCB board, ensuring that this utility model is stably installed on the PCB board.

[0028] Both sides of the upper shielding plate 42 are bent downward to form a first buckle plate 421. The first buckle plate 421 abuts against the outer side of the shielding side plate 44 to ensure that the upper shielding plate 42 stably covers the upper end surface of the extension seat 11.

[0029] The shielding rear plate 43 has a second buckle plate 431 bent forward on both sides. The second buckle plate 431 abuts against the outer side of the shielding side plate 44 and is fixed by laser welding to ensure that the shielding rear plate 43 stably covers the rear end face of the extension seat 11.

[0030] The lower end of the extension seat 11 is also provided with a limiting groove 111. The riveting piece 441 formed at the lower end of the shielding side plate 44 is pressed into the limiting groove 111 to form a riveting assembly, ensuring that the shielding side plate 44 stably covers the side of the extension seat 11.

[0031] The tongue plate 12 formed at the front end of the insulating base 1 also protrudes beyond the front surface of the slot 30 and the waterproof ring 5; after the front end of the waterproof TYPE-C connector is inserted into the countersunk hole 61 of the housing 6, the waterproof ring 5 is placed in the large groove 611 at the rear end of the countersunk hole 61 and forms a sealed contact, and the first sealing rib 501 is squeezed and deformed; the front end of the tongue plate 12 extends into the small groove 612 at the front end of the countersunk hole 61, and the small groove 612 is mated with the slot 50 to serve as an extension of the slot 30, which can reduce the length of the entire connector so that it can be used in a smaller space.

[0032] In summary, after the front end of the waterproof TYPE-C connector of this utility model is inserted into the countersunk hole 61 of the housing 6, the waterproof ring 5 is placed in the countersunk hole 61, and the first sealing rib 501 of the waterproof ring 5 is squeezed and deformed, so that the outer periphery of the front end of the metal inner shell 3 forms a sealed assembly with the countersunk hole 61, realizing the dustproof and waterproof function; at the same time, the inner surface of the waterproof ring 5 is formed with a second sealing rib 502, which protrudes from the inner wall of the slot 30 and is used to make sealing contact with the plug connector inserted into the slot 30, thus achieving a sealed waterproof, so as to meet the use of some scenarios with high waterproof performance requirements, which is extremely convenient to use and helps to improve the product's market competitiveness.
