Description

Technical Field

[0001] This utility model relates to the field of connectors, and in particular to a Type-C connector with a stable connection. Background Technology

[0002] USB Type-C, also known as USB-C or Type-C, is a new type of Universal Serial Bus (USB) hardware interface (USB interfaces also include Type-A and Type-B). It emerged alongside the latest USB 3.1 standard. It was released by the USB Developers Forum (USB-IF) in August 2014. Type-C was developed by the USB standardization organization to address the long-standing shortcomings of inconsistent physical interface specifications and unidirectional power transmission in USB interfaces. Its most distinctive feature is that its top and bottom are completely identical, supporting insertion in both directions. Compared to Micro-USB, users no longer need to distinguish between the front and back of the USB port. Furthermore, it integrates charging, display, and data transfer functions.

[0003] Existing Type-C connectors include a Type-C plug and a Type-C female socket, which are interlocked to form an electrical connection. The Type-C female socket typically includes an insulating body, two rows of conductive terminals embedded in the insulating body, and a shielding shell covering the insulating body. The front end of the shielding shell has a mating cavity for interlocking with the Type-C plug. Although it can achieve interlocking with the Type-C plug, the lack of a connection locking structure design with the Type-C plug results in poor connection stability and makes it difficult to guarantee a reliable electrical connection.

[0004] Therefore, a new technology needs to be developed to solve the above problems. Utility Model Content

[0044] Please refer to Figures 1 to 8 As shown, it illustrates the specific structure of an embodiment of the present invention.

[0045] A securely connected Type-C connector includes an insulating body 10, a terminal group, and a shielding shell 20. The terminal group is embedded and fixed on the insulating body 10, and the shielding shell 20 covers the insulating body 10. The insulating body 10 includes a first insulating member 11, a second insulating member 12, and a tongue member 13. The second insulating member 12 is stacked with the first insulating member 11, and the tongue member 13 is embedded and fixed with the front end of the first insulating member 11 and the front end of the second insulating member 12. The front end of the shielding shell 20 forms a mating cavity 21, and the tongue member 13 extends into the mating cavity 21.

[0046] The terminal group includes an upper terminal group 30 and a lower terminal group 40, which are respectively embedded and fixed together with the first insulating member 11 and the second insulating member 12. The first contact portion 31 of the upper terminal group 30 and the second contact portion 41 of the lower terminal group 40 are respectively exposed on the upper and lower surfaces of the tongue plate member 13. The first insulating member 11 and the second insulating member 12 are assembled and fixed together. The first welding portion 32 of the upper terminal group 30 and the second welding portion 42 of the lower terminal group 40 extend beyond the lower end of the first insulating member 11 and the lower end of the second insulating member 12, respectively. The first welding portion 32 of the upper terminal group 30 is arranged in a row in the left-right direction, and the second welding portion 42 of the lower terminal group 40 is arranged in a row in the left-right direction and is located in front of the first welding portion 32 of the upper terminal group 30.

[0047] The lower end face of the first insulating member 11 and the lower end face of the second insulating member 12 are flush with each other. The lower end face of the first welding part 32 of the upper terminal group 30 and the lower end face of the second welding part 42 of the lower terminal group 40 are flush with each other to facilitate subsequent welding.

[0048] The first insulating member 11 has a fixing hole 111 on its lower side, and the second insulating member 12 has a fixing post 121 on its upper side. The fixing post 121 is inserted into the fixing hole 111 for fixation. The lower end of the first insulating member 11 has a positioning post 112 protruding downwards. The positioning post 112 extends downwards to the lower end of the shielding shell 20, thus allowing it to be securely positioned with the external structure.

[0049] The shielding shell 20 is covered by an outer shell 50. Connecting arms 51 are provided on both the left and right sides of the front end of the outer shell 50. The connecting arms 51 are spaced apart from the shielding shell 20. The connecting arms 51 are provided with snap holes 52. In this way, after they are plugged into the Type-C plug, they can be locked together with the Type-C plug through the snap holes 52, thereby achieving a connection lock and making them firmly connected to the Type-C plug. This improves the connection stability and ensures a reliable electrical connection. Furthermore, the outer shell 50 can further enhance the shielding effect, making it more resistant to interference and improving the quality of signal transmission.

[0050] The lower end of the outer casing 50 has an integrally downward-extending pin 53, which allows it to be easily soldered and fixed to the PCB board, thereby providing installation stability. In this embodiment, the lower ends of both the left and right sidewalls of the outer casing 50 have integrally downward-extending pins 53, which extend downward beyond the lower end of the shielding shell 20.

[0051] The connecting arm 51 extends downward, and the upper end of the connecting arm 51 is integrally connected to the outer shell 50. The lower end of the connecting arm 51 extends downward integrally with the pin 53. The left and right sides of the front end of the outer shell 50 are integrally provided with a horizontal plate portion 54 protruding outward. The horizontal plate portion 54 extends out of the shielding shell 20, and the upper end of the connecting arm 51 is integrally connected to the horizontal plate portion 54 so that a distance is maintained between the connecting arm 51 and the shielding shell 20.

[0052] The left and right sidewalls of the outer shell 50 are each provided with a first protruding buckle 55, which extends upward and its upper end extends into the interior of the outer shell 50. The left and right sidewalls of the shielding shell 20 are each provided with a first buckle groove 22, and the first protruding buckle 55 is snapped into the corresponding first buckle groove 22 from top to bottom.

The rear side of the upper sidewall of the shielding shell 20 is provided with a second buckle groove 23, and the second protruding buckle 56 is snapped into the corresponding second buckle groove 23 from top to bottom. In this way, through the combined design of the first protruding buckle 55 and the first buckle groove 22, and the second protruding buckle 56 and the second buckle groove 23, the outer shell 50 and the shielding shell 20 can be stably connected together.

[0053] The rear end of the outer shell 50 is integrally connected to a shielding and limiting part 57. The shielding and limiting part 57 extends downward and in the left and right directions. The rear end of the shielding shell 20 is limited by the front end of the shielding and limiting part 57. In this way, the shielding and limiting part 57 can shield and limit the shielding shell 20 and the insulating body 10.

[0054] Both ends of the blocking and limiting part 57 have a fastening plate part 58 extending forward integrally. The fastening plate part 58 has a fastening hole 581. The left and right side walls of the outer shell 50 are provided with protrusions 59 protruding outward. The fastening plate part 58 abuts against the corresponding side wall of the outer shell 50. The protrusions 59 are positioned in the corresponding fastening holes 581.

[0055] In summary, the key design feature of this utility model lies in its use of an outer shell to enclose the shielding shell. Connecting arms are located on both the left and right sides of the front end of the outer shell, with snap-fit ​​holes on each arm. This allows the shell to engage with the Type-C plug via the snap-fit ​​holes, locking the connection securely and improving electrical stability. Furthermore, the shell enhances shielding, improving anti-interference capabilities and signal transmission quality. Finally, the downward-extending pins at the bottom of the shell facilitate soldering to the PCB board, providing installation stability.
