[0029] The present invention will be further described below in detail with reference to the accompanying drawings and specific embodiments, but the scope of implementation of the present invention is not limited thereto.

[0030] Example 1: Figures 1 to 10 As shown, the light leakage-proof TYPE-C connector described in this embodiment includes a plastic base 1 and a metal shell 2. The plastic base 1 has a fixing portion 11 and a connecting portion 12. The connecting portion 12 extends from one end of the fixing portion 11 along the axial direction of the fixing portion 11. The thickness of the connecting portion 12 is less than that of the fixing portion 11. A first sealing rib 13 is provided along the thickness direction of the fixing portion 11 along the peripheral edge of the end surface where the fixing portion 11 and the connecting portion 12 connect. The metal shell 2 covers the outer periphery of the plastic base 1. The first sealing rib 13 is interference-fitted with the inner peripheral wall of the metal shell 2. A conductive terminal 3 is embedded in the plastic base 1. One end of the conductive terminal 3 is partially exposed on the upper and lower surfaces of the connecting portion 12, and the other end of the conductive terminal 3 extends beyond the fixing portion 11 to facilitate soldering and fixing to an external PCB board.

[0031] The light leakage-proof TYPE-C connector of this embodiment effectively prevents light from leaking out of the connector socket by providing a first sealing rib 13 in the central area of ​​the plastic base 1 and utilizing the interference fit between the first sealing rib 13 and the inner peripheral wall of the metal shell 2, thereby achieving the light leakage-proof effect. There is no need to provide an inner and outer shell structure, and the manufacturing cost is lower.

[0032] In some embodiments of the light-leakage-proof TYPE-C connector of this embodiment, the plastic base 1 is formed by secondary overmolding, so that the plastic base 1 is better molded and has a stronger structure.

[0033] like Figures 3 to 7 As shown, in this embodiment of the light leakage-proof TYPE-C connector, in some embodiments, a first limiting groove 14 is formed at the other end of the fixing portion 11, and a first limiting arm 21 is formed on the metal housing 2 at a position corresponding to the first limiting groove 14, and the first limiting arm 21 is snapped into the first limiting groove 14. In this embodiment, by providing the first limiting groove 14 and snapping the first limiting arm 21 into the first limiting groove 14, the metal housing 2 and the plastic base 1 are mutually restrained, preventing loosening and making insertion and removal more reliable.

[0034] For example, Figure 3 As shown, the first limiting arm 21 is integrally formed with the metal housing 2 , and the first limiting arm 21 is riveted and clamped into the first limiting groove 14 .

[0035] like Figure 5 and Figure 7 As shown, in some embodiments of the light leakage-proof TYPE-C connector of this embodiment, there are two first limiting grooves 14, which are spaced apart along the width direction of the plastic base 1. This arrangement ensures that the metal housing 2 and the plastic base 1 are subjected to more balanced forces during insertion and removal, and the structure is more reliable.

[0036] like Figure 3 、 Figures 5 to 7 As shown, in some embodiments of the light leakage-proof Type-C connector of this embodiment, the other end of the fixing portion 11 is provided with two protruding limiting bosses 15 at the top corners; the metal housing 2 is formed with two limiting notches 22 at the top corners; and the limiting bosses 15 are received within the limiting notches 22. In this embodiment, the limiting bosses 15 cooperate with the limiting notches 22 to limit the position of the metal housing 2 and the plastic base 1 during insertion and removal, further improving structural reliability and facilitating assembly of the metal housing 2 and the plastic base 1.

[0037] like Figure 6 and Figure 7As shown, in the light leakage-proof TYPE-C connector of this embodiment, in some embodiments, the bottom surface of the fixing portion 11 is recessed with a second limiting groove 16, and the metal housing 2 is formed with a second limiting arm 23 at a position corresponding to the second limiting groove 16, and the second limiting arm 23 is snapped into the second limiting groove 16. In this embodiment, by providing the second limiting groove 16 and the second limiting arm 23, the metal housing 2 and the plastic base 1 are limited in position during the insertion and removal process, thereby improving structural reliability.

[0038] For example, Figure 7 As shown, the second limiting arm 23 is integrally formed with the metal housing 2 , and the second limiting arm 23 is riveted and clamped into the second limiting groove 16 .

[0039] Specifically, there are two second limiting arms 23 , and the two second limiting arms 23 are arranged opposite to each other.

[0040] like Figure 7 As shown, in some embodiments of the light leakage-proof Type-C connector of this embodiment, two bumps 24 are provided on the bottom surface of the metal shell 2, and the two bumps 24 are spaced apart along the width direction of the metal shell 2. In this embodiment, by providing two bumps 24, after the connector is mounted on an external PCB board, the bumps 24 are supported on the external PCB board, thereby forming support points through the bumps 24, ensuring the flatness of the connector after installation and facilitating mating.

[0041] Exemplarily, two protrusions 24 are provided near the connector socket.

[0042] like Figures 2 to 4 、 Figure 7 As shown, in some embodiments of the light leakage-proof Type-C connector of this embodiment, pins 25 are provided on both sides of the metal housing 2. In this embodiment, by providing pins 25, during installation, the pins 25 are plugged into an external PCB board, thereby firmly mounting the connector on the external PCB board. This makes the connector installation more stable and prevents the connector from loosening due to plugging and unplugging operations.

[0043] For example, Figure 7 As shown, two pins 25 are spaced apart on both sides of the metal shell 2. Such a configuration allows the connector to be more firmly mounted on the external PCB board.

[0044] like Figure 6 As shown, in some embodiments of the light leakage-proof Type-C connector of this embodiment, the plastic base 1 is provided with two spaced-apart positioning posts 17. Correspondingly, two positioning holes are provided on the external PCB board. During installation, the two positioning posts 17 are inserted into the positioning holes one by one, thereby forming a preliminary positioning for the connector, facilitating the positioning and soldering of the conductive terminals 3 and making installation more convenient.

[0045] Example 2: Figures 8 to 10 As shown, the difference between this embodiment and the first embodiment is that a recessed slot 18 is formed on the top surface of the fixing portion 11 of this embodiment, near the end of the connecting portion 12; the side of the recessed slot 18 near the connecting portion 12 penetrates the end surface of the fixing portion 11; a second sealing rib 19 is formed on the top surface of the fixing portion 11, around the periphery of the recessed slot 18; the second sealing rib 19 is in sealing contact with the inner top surface of the metal housing 2; a position-limiting stop 26 is formed on the inner top surface of the metal housing 2, and the position-limiting stop 26 is embedded in the recessed slot 18 to limit and secure the plastic base 1. The remaining structure is similar to that of the first embodiment and will not be repeated here.

[0046] This embodiment utilizes a locking slot 18 that cooperates with a stop 26 to mutually limit the position of the plastic base 1 and the metal housing 2 during insertion and removal, making the connector less susceptible to loosening due to insertion and removal forces, thereby enhancing structural reliability. Furthermore, a second sealing rib 19 seals against the inner top wall of the metal housing 2, preventing light from leaking through the locking slot 18 and ensuring a light-proof effect.

[0047] For example, Figures 8 to 10 As shown, there are two slots 18 , which are spaced apart along the width direction of the plastic base 1 . Correspondingly, there are two limit stops 26 , which correspond one-to-one with the two slots 18 . This arrangement further improves the structural reliability.

[0048] The above description is only a preferred embodiment of the present invention. Therefore, any equivalent changes or modifications made according to the structure, features and principles described in the scope of the present invention patent application are included in the scope of protection of the present invention patent application.
