[0030] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0031] See Figure 3-9 The image shows a waterproof Type-C connector for automotive boards. It can be used on automotive cockpit domain controllers to charge external devices such as mobile phones, iPads, and computers, as well as power VR / AR glasses and game controllers. Through connection with the cockpit domain controller, it provides customers with high-definition virtual reality images. Of course, it can also be used with other devices.

[0032] The vehicle-mounted waterproof TYPE-C connector includes a plastic body 2, a TYPE-C female connector 3 inserted into the plastic body 2, and a rear seat 4 installed at the rear end of the plastic body 2 and constraining the TYPE-C female connector 3 within the plastic body 2. The front end of the plastic body 2 has a slot 20, and the mating groove 30 at the front end of the TYPE-C female connector 3 is exposed in the slot 20. In use, after the wire-end TYPE-C connector is inserted into the slot 20 at the front end of the plastic body 2, the TYPE-C male connector of the wire-end TYPE-C connector is inserted into the mating groove 30 at the front end of the TYPE-C female connector 3, thereby achieving a connection for charging and data transmission.

[0033] The present invention mainly features the following design: a mating plate 21 is provided at the rear of the plastic body 2, which surrounds the rear of the plastic body 2. The mating plate 21 includes a fitting portion 211 adapted to the mounting hole of the housing and a baffle portion 212 located at the outer periphery of the front end of the fitting portion 211 and protruding from the outside of the fitting portion 211. A stepped groove is formed between the fitting portion 211 and the baffle portion 212. The fitting portion 211 of the mating plate 21 is embedded in the mounting hole of the housing, and the baffle portion 212 is blocked outside the mounting hole. This ensures a stable assembly between the waterproof TYPE-C connector at the vehicle board end of the present invention and the housing, preventing any shaking. Furthermore, the fitting portion 211 is adapted to the mounting hole of the housing, resulting in a very small gap after the fitting portion 211 is embedded in the mounting hole of the housing. The baffle portion 212 is blocked outside the mounting hole, thus providing a certain degree of waterproofing.

[0034] In this embodiment, the docking plate 21 is integrally formed and fixed to the periphery of the plastic body 2 during the injection molding of the plastic body 2. Of course, the docking plate 21 can also be integrally formed and fixed to the periphery of the plastic body 2 through secondary molding. Both of these methods can ensure that the docking plate 21 is stably fixed to the periphery of the plastic body 2.

[0035] To further improve the sealing effect of the mating plate 21 and the housing, and to enhance the waterproof effect, the following design is also made: the mating plate 21 is also provided with a sealing structure, and a sealed assembly is formed with the housing through the sealing structure, thereby enhancing the waterproof effect.

[0036] Specifically, the sealing structure includes at least the following three structures:

[0037] The first structure is as follows: the sealing structure is a sealing ring, which is fitted onto the insert 211 and abuts against the rear end face of the baffle 212; when assembled with the housing, the sealing ring is squeezed outside the mounting hole of the baffle 212 and the housing, thereby achieving a seal and enhancing the waterproof effect.

[0038] The second structure is as follows: The sealing structure is also a sealing ring, which has a stepped groove, meaning the cross-section of the sealing ring is L-shaped. This sealing ring is fitted onto the insert 211 and abuts against the rear end face of the baffle 212. During assembly with the housing, the stepped groove of the sealing ring is inserted into the mounting hole of the housing along with the insert 211. Specifically, the front end of the sealing ring is fitted onto the insert 211 and then inserted into the mounting hole of the housing, thus achieving a sealed assembly. The rear end of the sealing ring abuts against the baffle 212, causing it to be squeezed outside the mounting hole of the baffle 212 and the housing in the later stages, thereby achieving a seal and enhancing the waterproof effect.

[0039] The third structure is as follows: the sealing structure is a sealant, which is formed by filling the space between the mating plate 21 and the housing with adhesive. That is, after assembling the mating plate 21 with the mounting holes of the housing, adhesive is applied between the mating plate 21 and the housing using dispensing or other methods. Alternatively, adhesive can be applied to the mating plate 21 before assembling it with the mounting holes of the housing. Regardless of the method, the adhesive cures to form a sealant, providing better waterproofing. The adhesive can fill the space between the insert 211 and the mounting holes of the housing, as well as between the baffle 212 and the exterior of the mounting holes, resulting in a better seal and allowing the mating plate 21 to be firmly bonded to the housing, making the present invention more stably installed on the housing.

[0040] The assembly structure of the plastic body 2 and the TYPE-C female connector 3 is as follows:

[0041] The plastic body 2 has a mounting position 22 with a through slot 20 at its rear end. The TYPE-C female connector 3 passes through the mounting position 22, and the rear seat 4 abuts against the rear end of the TYPE-C female connector 3, thereby ensuring that the TYPE-C female connector 3 is stably installed inside the plastic body 2. The TYPE-C female connector 3 also has a waterproof ring 31 at its front periphery. The waterproof ring 31 is pressed against the mounting position 22 to form a sealed assembly, achieving internal waterproofing and further improving the waterproof performance of this invention.

[0042] The metal outer shell 32 of the TYPE-C female connector 3 is shorter than the metal inner shell 33, so that a stepped position 34 is formed between the outer surface of the metal inner shell 33 and the front end of the metal outer shell 32. The waterproof ring 31 is fitted on the stepped position 34 and abuts against the front end of the metal outer shell 32. The surface of the waterproof ring 31 is formed with at least two spaced waterproof ribs 311, which can improve the waterproof effect.

[0043] In this embodiment, the rear seat 4 is a conductor. The lower end of the rear seat 4 is provided with several solder feet 43 for soldering and fixing to the PCB board. The rear seat 4 contacts the metal outer shell 32 of the TYPE-C female connector 3, facilitating grounding of the TYPE-C female connector 3. Furthermore, a notch 41 is provided on the lower rear end of the rear seat 4 to improve the soldering effect. After the rear seat 4 is soldered and fixed to the PCB board via the solder feet 43, the entire vehicle-mounted waterproof TYPE-C connector is stably mounted on the PCB board. Because of the notch 41 on the lower rear end of the rear seat 4, air can circulate during the soldering process, thereby improving the soldering effect of the solder feet 43 and the pins of the terminals in the TYPE-C female connector 3 to the PCB board, and facilitating subsequent inspection of the soldering effect.

[0044] In some other embodiments, the rear seat 4 may also be made of an insulating material, such as rigid plastic.

[0045] The assembly structure of the plastic body 2 and the rear seat 4 is as follows:

[0046] The rear end face of the plastic body 2 is provided with an inlay groove 23, and the upper surface of the rear end of the plastic body 2 is also provided with a first insertion hole 231 that passes through the inlay groove 23; correspondingly, the front end of the rear seat 4 is formed with a forward-protruding inlay part 42, which is provided with a second insertion hole 421 corresponding to the first insertion hole 231. The inlay part 42 is inlaid in the inlay groove 23, and the baffle 5 is inlaid and fixed in the first insertion hole 231 and the second insertion hole 421 to lock the rear seat 4 to the rear end of the plastic body 2, preventing the rear seat 4 from accidentally coming out of the plastic body 2, and its assembly structure is stable.

[0047] In some embodiments, the baffle 5 has an opening 51 extending through its lower end face in the middle, forming two downwardly extending and spaced-apart first elastic arms 52 and second elastic arms 53 on both sides of the baffle 5. Both the first elastic arms 52 and second elastic arms 53 have barbs 50 formed on their exteriors, and both are inserted and held in the first insertion hole 231 and the second insertion hole 421. The first elastic arms 52 and second elastic arms 53 have a certain degree of elasticity, so that after being inserted and held in the first insertion hole 231 and the second insertion hole 421, they form a stable contact, and the barbs 50 are engaged and positioned with the first insertion hole 231, thereby ensuring a more stable assembly structure. This ensures that the baffle 5 is stably positioned in the first insertion hole 231, and consequently, that the lower parts of the first elastic arms 52 and second elastic arms 53 are also stably positioned in the second insertion hole 421, thus guaranteeing the stability of the assembly structure. In addition, the barbs 50 can be in multiple sets, with at least one set formed on the lower part of the first spring arm 52 and the second spring arm 53, which are used to engage and position with the second insertion hole 421 to further improve the stability of the assembly.

[0048] In some embodiments, to ensure that the structure of the inlay part 42 is more stable after being inlaid in the inlay groove 23, the following design is also made:

[0049] The inlay groove 23 is also provided with a number of limiting ribs 232, and the inlay part 42 is also provided with a limiting groove 422. The limiting ribs 232 and the limiting groove 422 are inlaid and positioned to ensure the stability of the assembly and to ensure the correct positioning of the assembly, so as to avoid the phenomenon of skewing.

[0050] In addition, the inner wall of the inlay groove 23 is provided with a first groove 233; the outside of the inlay part 42 is also provided with a positioning protrusion 423 that is adapted to the first groove 233. The positioning protrusion 423 is inlaid and positioned with the first groove 233, thereby further ensuring the stability of the assembly and further ensuring the alignment of the assembly to avoid the phenomenon of skewing.

[0051] The rear end of the plastic body 2 is also formed with a rearwardly protruding inset portion 24. The inner surface of the inset portion 24 forms the mounting position 22, and the outer surface of the inset portion 24 serves as part of the inlay groove 23. The inset portion 24 is also embedded inside the inlay portion 42, forming a second set of inlay assembly structure, which enables the rear seat 4 to be installed more stably at the rear end of the plastic body 2. The longitudinal section of the inlay groove 23, the inset portion 24, and the inlay portion 42 is semi-square. Both sides of the lower end of the inlay portion 42 are provided with baffles 426, which abut against both sides of the lower end of the inset portion 24 to limit the inset portion 24, thereby ensuring a more stable nesting installation of the inset portion 24 and the inlay portion 42.

[0052] The outer surface of the inlay portion 42 is provided with a first positioning hook 424 and a second positioning hook 425 distributed vertically opposite to each other, and a positioning channel 420 is formed between the first positioning hook 424 and the second positioning hook 425; the inlay groove 23 is also provided with a plurality of positioning ribs 234, which pass through the positioning channel 420 and are held and positioned by the first positioning hooks 424 and the second positioning hooks 425, thereby further improving the stability of the assembly structure. The first positioning hooks 424 and the second positioning hooks 425 are in two sets, respectively disposed on both sides of the inlay portion 42.

[0053] In summary, this utility model adds a mating plate 21 to the plastic body 2. The insert portion 211 of the mating plate 21 is embedded in the mounting hole of the housing, and the baffle portion 212 of the mating plate 21 blocks the outside of the mounting hole. This ensures that the waterproof TYPE-C connector of the vehicle board end of this utility model forms a stable assembly with the housing, preventing any shaking. Furthermore, the insert portion 211 is adapted to the mounting hole of the housing, so that the gap between them is extremely small after the insert portion 211 is embedded in the mounting hole of the housing. And the baffle portion 212 blocks the outside of the mounting hole, thus providing a certain degree of waterproof effect.
