[0036] For the convenience of understanding the present application, the present application will be described in more detail below with reference to the accompanying drawings and specific implementation manners.

[0037] An embodiment of the present application provides a Type-C connector. Please refer to Figures 1 to 4 . The Type-C connector 10 includes a housing 100, a connector body 200 and a fixing member 300. The connector body 200 is disposed within the housing 100. The connector body 200 includes terminals 210 for connecting with an external docking connector, which are the core components of the Type-C connector 10, and the housing 100 is used to cover and support the connector body 200.

[0038] As Figure 1 shown, an insertion interface 101 is formed at the front end of the housing 100 along the insertion direction, and an external docking connector is inserted into the connector body 200 from the insertion interface 101 to connect with the connector body 200. Define Figure 1 the X direction shown as the insertion direction. At the same time, asFigure 2 As shown, the rear end of the connector body 200 in the insertion direction needs to be exposed from the housing 100, so as to expose the terminals 210 on the connector body 200. The rear end of the terminals 210 in the insertion direction needs to be soldered to the circuit board. Therefore, it can also be understood that the connector body 200 can be inserted into the housing 100 from the rear end of the housing 100. Some limiting structures can be provided on the connector body 200 to prevent the connector body 200 from slipping forward on the housing 100. For example Figure 4 As shown, the welding feet 221 at the rear end of the metal shell 220 of the connector body 200 are set as the limiting structure and abutted against the rear end of the housing 100, so as to prevent the connector body 200 from slipping forward. However, there is no limiting structure for restricting the backward slipping of the connector body 200. Therefore, when the docking connector is inserted into the Type-C connector 10, a backward thrust along the insertion direction will be generated on the Type-C connector 10, resulting in the backward slipping of the Type-C connector 10.

[0039] In the embodiment of the present application, as Figures 1 to 4 shown, a fixing member 300 is provided to prevent the Type-C connector 10 from slipping backward. Of course, the fixing member 300 can also prevent the Type-C connector 10 from slipping forward. All in all, the fixing member 300 can fix the Type-C connector 10 in the housing 100 and prevent the Type-C connector 10 from moving. As Figures 1 to 4 shown, the fixing member 300 is inserted into the housing 100 along the first direction. The first direction forms an angle with the insertion direction (X direction) of the Type-C connector 10. Here, the meaning that the first direction forms an angle with the insertion direction of the Type-C connector 10 is that the first direction is not horizontal with the insertion direction of the Type-C connector 10 and has a certain angle, so that the fixing member 300 can be used to restrict the movement of the Type-C connector 10 in the insertion direction. In the embodiment of the present application, the first direction is perpendicular to the insertion direction of the Type-C connector 10, and the fixing member 300 is inserted vertically towards the connector body 200. It can also be said that the first direction is Figure 2 the Z direction shown or the reverse direction of the Z direction. As Figure 4 shown, if the fixing member 300 is inserted from above the housing 100, the first direction is the Z direction; if the fixing member 300 is inserted from below the housing 100, the first direction is the reverse direction of the Z direction. As Figure 2 and Figure 3 shown, the fixing member 300 is inserted into the housing 100 from the outside of the housing 100 and abuts against the connector body 200, so as to limit the connector body 200.

[0040] In one embodiment, as Figure 2 and Figure 4As shown, the Type-C connector 10 further includes a ground plate 400. The ground plate 400 is disposed on the outer side of the housing 100, and both ends of the ground plate 400 are welded to the ground pins of the external circuit board, thereby achieving grounding. As Figure 8 shown, the fixing member 300 includes opposite fixed ends 300a and insertion ends 300b. Referring to Figure 3 , the insertion end 300b is inserted into the housing 100 and abuts against the connector body 200. Referring to Figure 4 , the fixed end 300a is exposed outside the housing 100 and abuts against the ground plate 400, thereby fixing the ground plate 400. In this way, a single fixing member 300 can be used to fix both the connector body 200 and the ground plate 400 simultaneously.

[0041] Referring to Figure 2 , in an embodiment, the outer sidewall of the housing 100 is provided with a mounting groove 102, and the ground plate 400 is mounted in the mounting groove 102. Providing the mounting groove 102 to accommodate the ground plate 400 can prevent the ground plate 400 from being exposed outside the housing 100, and at the same time provides better limiting effect on the ground plate 400. As Figure 2 shown, the mounting groove 102 extends from the outer surface of the housing 100 towards the inside, so that the ground plate 400 can be embedded into the mounting groove 102 from the outside of the housing 100, facilitating the installation of the ground plate 400.

[0042] In the embodiment of the present application, as Figure 4 shown, the ground plate 400 is U-shaped, and both ends of the ground plate 400 are bent towards the rear end in the insertion direction, so as to facilitate welding the ground plate 400 to the circuit board at the rear. Correspondingly, as Figure 2 shown, the mounting groove 102 is also U-shaped, and both ends of the mounting groove 102 communicate with the rear side of the housing 100, so as to facilitate the ground plate 400 to extend out of the mounting groove 102 for welding with the circuit board.

[0043] Combining Figure 2 and Figure 4 , ground plates 400 can be provided on both sides of the housing 100 along the Z direction, and correspondingly, two fixing members 300 can also be provided. The two fixing members 300 are respectively used to fix the ground plates 400 on both sides.

[0044] In an embodiment, as Figure 8As shown, the fixing member 300 is T-shaped, including a connected fixing head 310 and an insertion rod 320. The fixing head 310 is located at the fixed end 300a, and the end of the insertion rod 320 is the insertion end 300b. The fixing head 310 is basically a long strip extending along the Y direction, and the insertion rod 320 is basically a long strip extending along the Z direction. The long strip-shaped fixing head 310 extending along the Y direction enables the fixing head 310 to abut against the outside of the housing 100 for limiting, preventing the fixing member 300 from being inserted excessively into the housing 100. At the same time, the fixing head 310 can be used to press against the grounding piece 400 to fix the grounding piece 400.

[0045] As Figure 8 shown, a snap structure 330 is provided at the insertion end 300b of the fixing member 300, and the snap structure 330 is arranged at the end of the insertion rod 320. The fixing member 300 is snap-connected to the connector body 200 through the snap structure 330, thereby preventing the fixing member 300 from disengaging from the housing 100.

[0046] Referring Figure 4 , the fixing member 300 is inserted in the front or rear side of the grounding piece 400 along the insertion direction. Figure 4 As shown, the fixing member 300 is inserted in the rear side of the grounding piece 400. In other embodiments, it can also be inserted in the front side, which is not limited herein. Referring Figure 9 , the dimension d1 of the fixing head 310 along the insertion direction is greater than the dimension d2 of the insertion rod 320 along the insertion direction, so that the front side and / or rear side of the fixing head 310 protrudes from the insertion rod 320, and the protruding part D abuts against the grounding piece 400. In the embodiment of the present application, since the fixing member 300 is inserted in the rear side of the grounding piece 400, therefore, Figure 9 As shown, it is necessary to make the front side of the fixing head 310 protrude from the insertion rod 320, so as to use the protruding part D to abut against and limit the grounding piece 400. In other embodiments, if the fixing member 300 is inserted in the front side of the grounding piece 400, it is necessary to make the rear side of the fixing head 310 protrude from the insertion rod 320, so as to use the protruding part to abut against and limit the grounding piece 400.

[0047] Referring Figure 4 , a protrusion 410 is provided on one of the fixing head 310 and the grounding piece 400, and a groove 311 is provided on the other. After the fixing member 300 is inserted into the housing 100, the protrusion 410 and the groove 311 cooperate with each other. The cooperation of the protrusion 410 and the groove 311 can further improve the fixing effect of the fixing member 300 on the grounding piece 400 and prevent the grounding piece 400 from shaking in the groove 311. As Figure 4In the illustrated embodiment, a protrusion 410 is provided on the grounding piece 400, and a groove 311 is provided on the fixing member 300. The protrusion 410 on the grounding piece 400 extends along the Z direction from the side of the grounding piece 400 closer to the fixing head 310 in the Z direction towards the fixing head 310. The groove 311 is provided on the fixing head 310 of the fixing member 300. The groove 311 on the fixing head 310 is provided on the protruding portion of the fixing head 310 protruding from the plug rod 320 on the front side, and the groove 311 extends along the Z direction from the side of the fixing head 310 closer to the grounding piece 400 in the Z direction away from the grounding piece 400. When the fixing member 300 is inserted into the housing 100 along the Z direction, the protrusion 410 can slide into the groove 311 and get stuck.

[0048] In one embodiment, as Figure 8 shown, the snap structure 330 includes a cantilever 331 extending along the first direction (Z direction), and a hook 332 provided at the end of the cantilever 331. The provision of the cantilever 331 makes the snap structure 330 more elastic and has a better clamping effect, avoiding hard contact between the snap structure 330 and the connector body 200.

[0049] Continuing to refer to Figure 8 , the cantilever 331 can be provided as two symmetrical ones, and of course, three or four can also be provided, which is not limited herein.

[0050] As Figure 5 shown, the connector body 200 is provided with a jack 222 for the snap structure 330 to pass through, and a receiving cavity 231 communicating with the jack 222 and used for receiving the hook 332. The provision of the receiving cavity 231 to receive the hook 332 allows sufficient opening space for the cantilever 331, avoiding damage to the cantilever 331 caused by the cantilever 331 being squeezed in a narrow space for a long time. It can be understood that, as Figure 5 shown, the size of the receiving cavity 231 is larger than the size of the jack 222, so that the cantilever 331 opens to both sides after passing through the jack 222, and the hook 332 is stuck at the top of the receiving cavity 231 to achieve clamping and prevent the fixing member 300 from coming outwards.

[0051] In one embodiment, as Figure 6 and Figure 7As shown, the connector body 200 includes a metal shell 220, an insulating member 230, and the terminals 210 described above. A welding pin 221 is provided at the rear end of the metal shell 220 along the insertion direction. The welding pin 221 is a grounding pin, and the welding pin 221 is welded to the ground pin of the circuit board, so that the metal shell 220 is grounded, playing a role of grounding and shielding. The insulating member 230 is disposed within the metal shell 220. The terminals 210 are embedded in the insulating member 230, and the contacts 211 of the terminals 210 are exposed on the front side of the insulating member 230 along the insertion direction. After the external docking connector is inserted into the Type-C connector 10, the terminals 210 of the docking connector come into contact with the contacts 211 of the terminals 210 at the front end of the insulating member 230 to achieve signal transmission. As Figure 6 and Figure 7 shown, a jack 222 is provided on the metal shell 220, and a receiving cavity 231 is provided on the insulating member 230. After the insulating member 230 and the metal shell 220 are assembled, the jack 222 is located above the receiving cavity 231, so that the hook 332 of the fixing member 300 passes through the jack 222 and enters the receiving cavity 231. As Figure 6 and Figure 7 shown, the jack 222 is an opening provided on the metal shell 220, and the receiving cavity 231 is a groove provided on the insulating member 230.
