[0029] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0030] like Figures 1 to 5As shown, a stable connection type USB Type-C female connector includes an inner core 10, an inner shell 20, and an outer shell 30. The inner core 10 has a front positioning groove 101 and a rear positioning groove 102 at its middle and tail ends, respectively, and protrusions 103 on its opposite side walls. The inner shell 20 includes an annular shell 21 and an L-shaped plate 22 disposed at the tail end of the annular shell 21. A slot 2201 is formed between the L-shaped plate 22 and the annular shell 21. A front positioning member 211 and a rear positioning member 212 are respectively disposed at the middle and tail ends of the annular shell 21. A first insert 213 is disposed at the middle of the outer wall of the annular shell 21. When the inner core 10 is embedded in the annular shell 21, the front positioning member 211 and the rear positioning member 212 are positioned at their respective ends. Positioning components 212 are respectively embedded in the front positioning groove 101 and the rear positioning groove 102, and the protrusion 103 is embedded in the slot 2201. The outer shell 30 includes a cover 31, a sealing plate 32 and a side plate 33. The side wall of the cover 31 is provided with a first insertion port 310 and a second insertion plug 311. The sealing plate 32 is connected to one end of the cover 31. A pair of side plates 33 are respectively set at opposite ends of the sealing plate 32 and bent to one side of the cover 31. The side plate 33 is provided with a second insertion port 330, and the second insertion plug 311 is embedded in the second insertion port 330. When the inner shell 20 is embedded in the cover 31, the first insertion plug 213 is embedded in the first insertion port 310 and fixedly connected.
[0031] In this invention, the inner core 10 extends from the side of the inner shell 20 with the L-shaped plate 22 into the inner cavity 200 formed by the annular shell 21. After moving within the annular shell 21, the inner core 10 is positioned by the cooperation of the front positioning groove 101 and the front positioning member 211, and simultaneously the protrusion 103 is embedded in the slot 2201. The bendable member located at the tail end of the annular shell 21 is bent and embedded in the rear positioning groove 102 to form the rear positioning member 212. The cooperation of the positioning groove and the positioning member can prevent the inner core 10 from moving back and forth relative to the inner shell 20. The protrusion 103 and the slot The cooperation of 2201 ensures the stability of the tail end of the inner core 10 (i.e., the side not extending into the inner cavity 200 of the annular shell 21), thereby stably connecting the inner core 10 and the inner shell 20. Then, by inserting the first plug 213 on the inner shell 20 into the first socket 310 on the cover 31, the inner shell 20 can be stably mounted on the outer shell 30. Furthermore, the sealing plate 32 on the outer shell 30 blocks one side of the cover 31, and its second socket 330 on the side plate 33 fits onto the second plug 311 on the cover 31, ensuring the stability of the sealing plate 32. Through the above design, a stable connection is achieved between the inner core 10, the inner shell 20, and the outer shell 30. Moreover, during the insertion process, the presence of the sealing plate 32 ensures the stability of the inner core 10 and the inner shell 20, guaranteeing the structural stability of the USB Type-C female connector body and its application.
[0032] Preferably, a support block 104 is provided on the inner core 10 below the protrusion, and a slot 2202 is formed between the support block 104 and the protrusion 103. The horizontal plate on the L-shaped plate 22 is embedded in the slot 2202. The stability in the vertical direction at the tail end can be ensured by the coordinated action of the L-shaped plate 22, the protrusion 103 and the support block 104. By providing a guide cutout 1041 on the support block 104, it is easy for the horizontal plate on the L-shaped plate 22 to be embedded in the slot 2202.
[0033] Preferably, the sealing plate 32 is connected to the tail end of the cover 31 through the first bending part 3a, and the side plate 33 is connected to the sealing plate 32 through the second bending part 3b. The outer shell 30 is an integral structure. When the outer shell 30 is in its final state, the sealing plate 32 is first blocked at the tail end of the cover 31 by bending through the first bending part 3a, and then the side plate 33 is bent towards the cover 31 by bending through the second bending part 3b, so that the second insertion port 330 is fitted onto the second plug-in 311. The pulling effect of the side plate 33 on the sealing plate 32 can make the position of the sealing plate 32 stable.
[0034] Furthermore, since the first bending portion 3a has a relatively long structure, multiple perforated structures can be provided on the first bending portion 3a to reduce bending resistance and facilitate the bending action of the first bending portion 3a.
[0035] In addition, the annular shell 21 is provided with a protrusion 21a and an elastic support 21b, which can facilitate the stable connection between the external device and the USB type-c female connector after the inner core 10 is plugged in and the external device is inserted through the clamping action of the protrusion 21a and the elastic support 21b.
[0036] like Figures 5 to 6 As shown, the inner core 10 of this utility model includes an upper terminal module 11, a lower terminal module 12, a partition 13, and an injection-molded shell 14. The upper terminal module 11 includes an upper base 111 and a plurality of first terminals 112 disposed on the upper base 111. The lower terminal module 12 includes a lower base 121 and a plurality of second terminals 122 disposed on the lower base 121. The upper terminal module 11 and the lower terminal module 12 respectively abut against the upper end and the lower end of the partition 13. The injection-molded shell 14 encloses the upper terminal module 11 and the lower terminal module 12. At least a portion of the first terminals 112 and the second terminals 122 are exposed on the injection-molded shell 14 for communication with external devices. The front positioning groove 101 and the rear positioning groove 102 are integrally formed during the injection molding of the injection-molded shell 14. The protrusion 103 and the support block 104 are formed on the lower terminal module 12, specifically on its lower base 121.
[0037] Preferably, the first terminal 112 and the second terminal 122 located on the outer side are provided with inclined support parts, namely the first support part 1121 and the second support part 1221, respectively. The first support part 1121 and the second support part 1221 can be formed by bending the corresponding outer terminal after setting the groove 1120. The first support part 1121 and the second support part 1221 abut against the partition plate 13, and the stability of the terminal located on the outer side without a support structure can be ensured by the abutment support between the support part and the partition plate 13. That is, when the upper row terminal module 11 and the lower row terminal module 12 are positioned on the partition plate 13, and when they are injection molded and wrapped with the injection molded shell 14 after positioning, the stability of all terminals can be ensured, and the stability and quality of the inner core 10 after molding can be guaranteed.
[0038] In addition, the lower base 121 is provided with two positioning posts 1211, and the upper base 111 and the partition 13 are respectively provided with two first positioning holes 1111 and two second positioning holes 131. The positioning posts 1211 pass through the second positioning holes 131 and the first positioning holes 1111 in sequence. Furthermore, the lower base 121 is also provided with multiple 1212 inserts, the upper base 111 is provided with multiple first insertion holes 1112, and the partition 13 is provided with second insertion holes 132. The inserts 1212 pass through the second insertion holes 132 and the first insertion holes 1112 in sequence to achieve the spacing between adjacent terminals, which can ensure the accurate relative positions of the upper row terminal module 11, the lower row terminal module 12 and the partition 13.
