DETAILED DESCRIPTION

[0029] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of them. The embodiments of the basic utility model and all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present utility model.

[0030] according to Figure 1 、 Figure 2 、 Figure 6 、 Figure 7 and Figure 8 As shown, a vehicle-mounted multi-interface right-angle board-end waterproof connector includes a shell 2, which is provided with a mounting end 3, and a power plug cavity 5 and a differential plug cavity 6 for plugging in. A power terminal group is arranged in the shell 2, and one end of the power terminal group extends axially from the mounting end 3 to the outside, and the other end extends axially into the power plug cavity 5; a differential signal terminal group is arranged in the shell 2, and one end of the differential signal terminal 8 extends axially from the mounting end 3 to the outside, and the other end extends axially into the differential plug cavity 6; a metal sheet 7 is arranged in the shell 2 to shield the differential signal terminal group; the power terminal group, the differential signal terminal group and the metal sheet 7 all have a right-angle structure.

[0031] This design uses a shared housing 2 for the power terminal group and the differential signal terminal group to simultaneously transmit power signals and differential signals. This reduces the space occupied by the connector, and the use of a power plug cavity 5 and a differential plug cavity 6 makes the interfaces spatially independent of each other for sub-assembly of the terminals. The metal sheet 7 is used to avoid mutual interference between the transmitted power signal and the differential signal, thereby ensuring the quality and stability of signal transmission.

[0032] according to Figure 2 As shown, a sealing groove 4 for embedding the sealing body 1 is provided on the end face of the mounting end 3. The sealing body 1 is used to seal between the mounting end 3 and the mounting plate, thereby ensuring the sealing of the internal structure of the connector and extending the service life of the internal terminal. The interference fit between the sealing body 1 and the sealing groove 4 is conducive to enhancing the holding force of the sealing body 1.

[0033] An anti-slip groove 11 connected to the sealing groove 4 is provided on the mounting end 3, and an anti-slip mechanism connected to the sealing body 1 is embedded in the anti-slip groove 11. The anti-slip mechanism and the sealing body 1 are made of the same material. The sealing stability of the sealing body 1 is increased by the anti-slip mechanism, and the anti-slip mechanism is interference fit with the anti-slip groove 11, thereby increasing the holding force of the anti-slip mechanism in the anti-slip groove 11.

[0034] according to Figure 3 As shown, the anti-slip mechanism includes a positioning portion 13 and a connecting portion 12 connecting the positioning portion 13 and the sealing body 1. The positioning portion 13 is preferably a circular structure or a polygonal structure.

[0035] Several protrusions 9 are staggered and arranged on the opposite inner walls of the sealing groove 4. The protrusions 9 are helpful to ensure the retention force of the sealing body 1 in the sealing groove 4, ensuring that it will not separate from the shell 2 during circulation or transportation, thereby improving the stability of the sealing body 1.

[0036] according to Figure 4 As shown, the power terminal group includes a plurality of power terminals 10, and the power terminal 10 is composed of a narrow body portion A102 and a wide body portion A103, and the narrow body portion A102 is located at both ends of the wide body portion A103, and the wide body portion A103 is wrapped in the shell 2, and the narrow body portion A102 is used for plugging, and the strength of the terminal can be increased by the wide body portion A103, and the step formed at the connection between the narrow body portion A102 and the wide body portion A103 has the function of matching impedance.

[0037] The wide body portion A103 is provided with a fixing portion 101 to connect the power terminals 10 in series. The provision of the fixing portion 101 is conducive to the installation of the power terminal group. The fixing portion 101 is loaded into the housing 2 to form a whole, which is conducive to ensuring the position of the terminals.

[0038] according to Figure 5 As shown, the differential signal terminal group includes a plurality of differential signal terminals 8, and the differential signal terminal 8 is composed of a narrow body portion B801 and a wide body portion B803. The narrow body portion B801 is arranged at both ends of the wide body portion B803, and the wide body portion B803 is wrapped in the shell 2. The narrow body portion B801 is used for plugging, and the strength of the terminal can be increased by the wide body portion B803. The step structure formed at the connection between the narrow body portion B801 and the wide body portion B803 has the function of matching impedance, and only has the function of matching impedance at the Ethernet end, and the 8-pin end cannot play the corresponding function.

[0039] The side of the wide body B803 forms a limiting protrusion 802 protruding outward, which plays a limiting role during injection molding to prevent the terminal from being offset during the punching process. By changing the cross-sectional shape here, the composite dielectric constant is changed and the impedance is optimized.

[0040] The metal sheet 7 is located on both sides of the differential signal terminal 8, and the end of the metal sheet 7 forms an Ethernet terminal 14. The Ethernet terminal 14 extends axially from the mounting end 3 to the outside for plugging into the Ethernet port.

[0041] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
