[0039] Please refer to Figures 1 to 3 , which shows the specific structure of the first preferred embodiment of the present invention, including an insulating body 10 , a plurality of spring terminals 20 and a shielding shell 30 .

[0040] The insulating body 10 includes a base 11 and a tongue plate 12 extending forward from the base 11. In this embodiment, the front end of the insulating body 10 is formed of a plastic outer dimension that conforms to the USB 3.0A female protocol. Furthermore, the rear end of the base 11 is provided with a forwardly recessed fixing slot 101, which extends forward into the interior of the tongue plate 12. The front end of the tongue plate 12 is provided with a plurality of slots 102, each of which communicates with the fixing slot 101. Furthermore, the rear end of the base 11 is provided with a plurality of recessed terminal slots 103. The tongue plate 12 is provided with a window 104, which communicates with the fixing slot 101 and is located behind the plurality of slots 102. The window 104 is square in shape. Furthermore, an outer shell 13 extends from the base 11. The outer shell 13 has a forwardly opening receiving cavity 105, within which the tongue plate 12 is located.

[0041] The spring terminals 20 are fixed to the base 11 at intervals. Each spring terminal 20 has a resilient contact portion 21 that overhangs the surface of the tongue plate 12. In this embodiment, four spring terminals 20 are spaced and arranged side by side. The spring terminals 20 are inserted and fixed in the terminal slots 103 from back to front, with the resilient contact portions 21 overhanging the windows 104. Furthermore, each spring terminal 20 has a connecting portion 22 formed thereon. A soldering foot 23 extends rearward from the rear end of the spring terminal 20 for soldering to an external circuit board. The soldering foot 23 extends rearwardly outside the base 11.

[0042] The shielding shell 30 is wrapped around the base 11, and the tongue plate 12 is suspended within the shielding shell 30. In this embodiment, the shielding shell 30 is inserted into the accommodating cavity 105 from front to back, resulting in a simple structure and stable assembly. Furthermore, the outer wall of the shielding shell 30 is aligned with the inner wall of the accommodating cavity 105. The rear end of the shielding shell 30 has two symmetrically arranged fixing legs 31, which extend backward through the base 11 and are used for soldering to the external circuit board.

[0043] A PCB 40 is mounted within the insulating body 10. The front surface of the PCB 40 features multiple, spaced-apart, flat-type gold fingers 41. Each flat-type gold finger 41 is exposed on the surface of the tongue plate 12 and located in front of the elastic contact portion 21. The rear end of the PCB 40 extends rearward from the base 11. In this embodiment, there are five flat-type gold fingers 41, which conform to the USB 3.0A motherboard association's definition. The five flat-type gold fingers 41 are evenly spaced and arranged side by side. Furthermore, the PCB 40 is inserted into the fixing slot 101 from back to front, with the multiple flat-type gold fingers 41 positioned in corresponding slots 102. This provides a simple structure and a secure and reliable installation. Furthermore, the PCB 40 has multiple first gold fingers 42. The connecting portion 22 is in contact with and electrically connected to the corresponding first gold fingers 42, and the connecting portion 22 is soldered to the corresponding first gold fingers 42, thereby integrating the spring terminal 20 with the PCB 40. Furthermore, the PCB 40 has multiple recesses 43 formed throughout its upper and lower surfaces to provide space for the elastic contact portions 21 to deform. Each elastic contact portion 21 is positioned directly above a corresponding recess 43, ensuring more stable and reliable contact between the elastic contact portions 21 and the external connector. Furthermore, the rear end of the PCB 40 has multiple connecting terminals 44 spaced apart from one another. These terminals 44 are used to securely connect to an external circuit board.

[0044] The assembly process of this embodiment is described in detail as follows:

[0045] First, prepare the insulating body 10, spring terminal 20, shielding shell 30 and PCB board 40 in advance. Then, place the connecting part of the spring terminal 20 on the first gold finger 42 and weld it to fix it. In this way, multiple spring terminals 20 are combined and fixed with the PCB board 40. Then, insert the PCB board 40 into the fixing groove 101 from back to front and fix it. After being inserted into place, the multiple spring terminals 20 are respectively inserted into the corresponding terminal grooves 103 and fixed. Then, insert the shielding shell 30 into the accommodating cavity 105 from front to back and fix it tightly.

[0046] Please refer to Figures 4 to 6As shown, it shows the specific structure of the second preferred embodiment of the utility model. The specific structure of this embodiment is basically the same as the specific structure of the first preferred embodiment mentioned above, except that:

[0047] In this embodiment, the insulating body 10 does not include an outer shell 13; the shielding shell 30 completely encloses the insulating body 10. Furthermore, the spring terminals 20 do not have solder pins 23 for soldering to an external circuit board. Instead, each spring terminal 20 has a bent, extending connection pin 24 at its rear end. Correspondingly, the PCB 40 has multiple second gold fingers 45. These connection pins 24 contact and connect with corresponding second gold fingers 45, and are soldered to the corresponding second gold fingers 45. Furthermore, the rear surface of the PCB 40 has multiple third gold fingers 46. These multiple second gold fingers 45 and the multiple flat gold fingers 41 are respectively connected to corresponding third gold fingers 46. These multiple third gold fingers 46 are used for soldering to an external circuit board.

[0048] The assembly process of this embodiment is described in detail as follows:

[0049] First, prepare the insulating body 10, spring terminal 20, shielding shell 30 and PCB board 40 in advance. Then, place the connecting pin 24 of the spring terminal 20 on the second gold finger 45 and weld it to fix it. In this way, multiple spring terminals 20 are combined and fixed together with the PCB board 40. Then, insert the PCB board 40 from the back to the front into the fixing groove 101 and fix it. After being inserted into place, the multiple spring terminals 20 are respectively inserted into the corresponding terminal grooves 103 and fixed. Then, the shielding shell 30 is fitted on the outside of the insulating body 10 and fixed.

[0050] The design focus of the utility model is that by arranging a PCB board in the insulating body, the PCB board has flat-type gold fingers, which eliminates the need for multiple flat terminals for assembly, effectively reducing the number of parts, thereby simplifying the product structure and making production and assembly simple and quick. At the same time, the PCB board can share the same board with external equipment, which is beneficial to saving installation space and greatly reducing costs.

[0051] The above description is merely a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
