[0033] In this embodiment, the first GND terminal 10, the first VBUS terminal 20, the first CC terminal 50, the second CC terminal 60, the second VBUS terminal 30, and the second GND terminal 40 are an integrated terminal group, that is, the six terminals are connected together on the same material strip, and the six welding legs of the six terminals are connected side by side on the same side of the material strip. The structure is simple, and this integrated terminal material strip 1 is suitable for continuous stamping production. Compared with the two-row terminal group, the integrated terminal material strip 1 design of this embodiment makes the terminal position accuracy better controllable.

[0034] In this embodiment, the first vertical plate portion 102 is formed by bending upward from the left side of the first horizontal plate portion 101, the second vertical plate portion 202 is formed by bending upward from the left side of the second horizontal plate portion 201, the third vertical plate portion 302 is formed by bending upward from the right side of the third horizontal plate portion 301, and the fourth vertical plate portion 402 is formed by bending upward from the right side of the fourth horizontal plate portion 401, so that the first horizontal plate portion 101, the second horizontal plate portion 201, the third horizontal plate portion 301, and the fourth horizontal plate portion 401 can be designed with a larger width size, which not only meets the demand for transmitting a larger current, but also helps to more firmly position the terminal group in the insulating body.

[0035] The top and bottom of the vertical plate of the same terminal are used as the upper and lower contact parts of the corresponding terminals. In this way, the 4PIN terminal provides the TYPE-C standard 8PIN current transmission terminal contact, which is compatible with the fast charging protocol launched by the USB Association. The structure is simple and ingenious, which is convenient for the integrated design of the terminal group and easy to manufacture. It replaces the traditional upper and lower row terminal design, reduces the number of welding feet, simplifies the process, and improves the positioning accuracy of the female terminal group in the insulating body, which is conducive to improving the process efficiency and yield, and effectively reducing costs. Since the traditional 8PIN terminal is changed to a 4PIN terminal, the design size of each PIN terminal is more sufficient, which is convenient for designing larger terminals as needed. The cross-sectional area of ​​the contact part is effectively increased to meet the requirements of greater current transmission, which is conducive to further improving the fast charging effect. Moreover, the structural strength of the terminal group is better, which also strengthens the overall structural strength, durability and reliability of the tongue and the TYPE-C fast charging female head, and it is not easy to cause the TYPE-C fast charging female head to be damaged when electronic products are plugged in and out of charging, collision, etc. Comparison Fig.16 and Fig.17As shown, if the first GND upper row contact portion 12 and the second GND upper row contact portion 42 are designed as upper and lower rows of spacing, the area of ​​the local cross-section of the terminal is significantly smaller than the area of ​​the local cross-section of the terminal when the first GND upper row contact portion 12 and the second GND upper row contact portion 42 are respectively formed at the top and bottom of the first vertical plate portion 102. In other words, by adopting the vertical plate portion structure, that is, by using the first vertical plate portion 102, the second vertical plate portion 202, the third vertical plate portion 302, and the fourth vertical plate portion 402, the function of one terminal carrying two contacts is realized. For the PIN terminal, the cross-sectional area of ​​the contact portion, the cross-sectional area of ​​the fixing portion, and the cross-sectional area of ​​the welding foot and other parts can all be designed with a large area to meet the needs of large current transmission.

[0036] Since the first vertical plate portion 102, the second vertical plate portion 202, the third vertical plate portion 302, and the fourth vertical plate portion 402 are all formed by stamping on a metal plate and then bending it, it is very easy to stamp out the positioning groove C1 and the card point C2, and to design the shape and size of the top and bottom of the first vertical plate portion 102, the second vertical plate portion 202, the third vertical plate portion 302, and the fourth vertical plate portion 402. Moreover, the first vertical plate portion 102, the second vertical plate portion 202, the third vertical plate portion 302, and the fourth vertical plate portion 402 after bending make the overall structural strength of the female terminal group 100 better, and further make the connector more resistant to plugging and unplugging, and avoid the tongue breakage phenomenon.

[0037] During production, the female terminal group 100 can be integrally injection molded and fixed in the insulating body 200. The left and right sides of the tongue 2001 of the insulating body 200 are designed with hook adaptation protrusions at the front end to match the hook of the male head. The hook adaptation protrusion can be formed integrally by only the plastic part of the tongue 2001 itself, or a metal part can be embedded, and a hook adaptation protrusion protrusion imitation part is designed on the metal part. In this way, the hook adaptation protrusion imitation part is exposed on the left and right sides of the tongue 2001 as the hook adaptation protrusion, or the hook adaptation protrusion imitation part can be correspondingly embedded in the plastic hook adaptation protrusions on the left and right sides of the tongue 2001 to form the hook adaptation protrusion together.

[0038] In this embodiment, the TYPE-C fast charging female connector also includes a metal middle spacer 400, which is injection molded together with the female connector terminal group 100 and fixed in the insulating body 200. Specifically, a positioning groove C1 is provided at the front end of the first GND terminal 10 and the second GND terminal 40, and the metal middle spacer 400 is inserted into the positioning groove C1 to form contact and positioning with the corresponding first GND terminal 10 and the second GND terminal 40; the metal middle spacer 400 includes a left partition part 410 and a right partition part 420 with a left-right symmetrical design (the first GND terminal 10 and the second GND terminal 40 are also symmetrical structures to each other), and the left partition part 410 and the right partition part 420 are inserted into the corresponding positioning groove C1; and, the first GND terminal 10 and the second GND terminal 40 are provided with A card point C2 is provided to prevent the metal middle partition 400 from slipping forward, and the left partition part 410 and the right partition part 420 are restricted by the rear ends of the corresponding card point C2; wherein, the left partition part 410 and the right partition part 420 are connected into one body through a front connecting arm 430, which is convenient for producing the metal middle partition 400, and the metal middle partition 400 can also be inserted into the female terminal group 100 at one time; the front connecting arm 430 is located in front of the first VBUS terminal 20 and the second VBUS terminal 30 and maintains a spacing; of course, in other embodiments, the left partition part 410 and the right partition part 420 can also be set separately from each other.The left partition part 410 and the right partition part 420 both include a horizontal substrate part 4001, a rear end folding plate part 4002 and a C-shaped bending part 4003; the horizontal substrate part 4001 is provided with a card slot C3 extending forward and backward, the lower end of the rear end folding plate part 4002 is integrally connected to the rear end of the horizontal substrate part 4001, and is bent and extended upward, so that the upper end of the rear end folding plate part 4002 is located at a height higher than the horizontal substrate part 4001; the C-shaped bending part 4003 includes an integrally connected top wall 4031, an outer side wall 4032 and a bottom wall 4033, the upper and lower ends of the outer side wall 4032 are respectively connected to the outer ends of the top wall 4031 and the bottom wall 4033, so as to form a C-shaped structure, the left partition part 410 and the right partition part 4 The C-shaped bending portions 4003 of 20 are all designed to be opened inwards. Considering the smoothness of assembly, a guide portion 4034 extending obliquely downward and backward can be connected to the rear end of the bottom wall 4033; the structural design of the left partition portion 410 and the right partition portion 420 effectively strengthens the structural strength of the tongue 2001; the front end of the top wall 4031 is connected to the upper end of the rear end folding plate portion 4002, and the card slot C3 penetrates the rear end of the horizontal substrate portion 4001 and the rear end folding plate portion 4002 backward until it extends to the top wall 4031 (for example: about 1 / 3 to 1 / 2), so that the internal rear end surface formed by the card slot C3 on the top wall 4031 can be used to form a mutual limitation with the rear end surface of the card point C2 to prevent the metal middle partition 4000 from slipping forward.

[0039] The assembly process of the TYPE-C fast charging female connector is as follows: First, prepare the female terminal group 100 and the metal middle spacer 400; the female terminal group 100 is linearly conveyed in the form of a material belt on the continuous stamping production material belt, and the metal middle spacer 400 is inserted into the female terminal group 100 from front to back at the insertion station. During the relative front-to-back displacement of the female terminal group 100 and the metal middle spacer 400, the first vertical plate portion 102 and the fourth vertical plate portion 402 pass through the corresponding C-shaped bending portion 4003 and the card slot C3 until the positioning groove C1 is stuck in the internal front end surface of the card slot C3, and the card point C2 is buckled into the card slot. The metal spacer 400 and the female terminal assembly 100 are reliably assembled and positioned in the left-right direction, the front-back direction, and the up-down direction. The metal spacer 400 and the first GND terminal 10 and the second GND terminal 40 are firmly combined, such as Figure 10-12 As shown (the material strip is not shown); Then, the assembled female terminal assembly 100 and the metal middle spacer 400 are injection molded together (also referred to as embedded injection molding), so that the female terminal assembly 100 and the metal middle spacer 400 are embedded in the insulating body 200; usually, the metal middle spacer 400 enters the injection mold along with the material strip where the female terminal assembly 100 is located; Then remove the terminal strip 1 to obtain a single TYPE-C fast charging female connector body (the TYPE-C fast charging female connector body includes an insulating body 200 and a female connector terminal group 100 and a metal middle spacer 400 disposed on the insulating body 200); Then, a single TYPE-C fast charging female plug body is installed into the prepared shell 300, for example, the TYPE-C fast charging female plug body is installed into the shell 300 from the back to the front, and the preset spring pieces on the shell 300 are inserted into the corresponding recesses on the insulating body 200 to realize the mutual assembly and positioning of the TYPE-C fast charging female plug body and the shell 300.
