Description

Technical Field

[0001] The present invention relates to the field of TYPE-C fast charging female connector technology, and in particular to a simplified implementation method of a TYPE-C 14 PIN fast charging female connector that complies with association specifications. Background Art

[0002] With the promotion of TYPE-C connectors, it has become very common to use TYPE-C interfaces to facilitate charging of electronic devices. According to the USB Association, the standard TYPE-C female head requires 24PIN terminals, which include charging terminals, data transmission terminals, etc. There are many terminals, the adjacent terminals are densely packed, the spacing is small, and the manufacturing process is complicated.

[0003] Based on this, the industry has improved and designed some simple TYPE-C connectors for the use of TYPE-C connectors that are only used for charging and have no data transmission function (in the fields of power sockets, cars, power banks, wireless headphones, etc.), which mainly reduce the number of terminals. For example, CN 209344410 U discloses a simple TYPE-C connector solution, which has a standard 8-PIN (4-PIN GND terminal and 4-PIN VBUS terminal) charging terminal and 2-PIN CC terminal, which can support the fast charging protocol. However, it does not comply with the latest version of the association specification, for example: there is no A6 / A7 / B6 / B7 PIN terminal, and the association standard defines that the 4-PIN terminal has no solder pins, A6 / A7 are short-circuited with each other, and B6 / B7 are short-circuited with each other.

[0004] In addition, in an existing simplified TYPE-C connector solution, a terminal module is arranged in two rows, upper and lower, in an insulating body. The terminal module includes a first PIN pin (A1), a second PIN pin (A4), a third PIN pin (A5), a fourth PIN pin (A9), and a fifth PIN pin (A12) in the upper row, and also includes a sixth PIN pin (B12), a seventh PIN pin (B9), an eighth PIN pin (B5), a ninth PIN pin (B4), and a tenth PIN pin (B1) in the lower row; the two PIN pin soldering feet of the first PIN pin (A1) and the sixth PIN pin (B12) are simultaneously soldered to a soldering pad of a PCB circuit board; the two PIN pin soldering feet of the second PIN pin (A4) and the seventh PIN pin (B9) are simultaneously soldered to a soldering pad of a PCB circuit board; The soldering foot of the third PIN pin (A5) is separately soldered to a soldering pad of the PCB circuit board; the soldering foot of the eighth PIN pin (B5) is separately soldered to a soldering pad of the PCB circuit board; the soldering feet of the fourth PIN pin (A9) and the ninth PIN pin (B4) are simultaneously soldered to a soldering pad of the PCB circuit board; the soldering feet of the fifth PIN pin (A12) and the tenth PIN pin (B1) are simultaneously soldered to a soldering pad of the PCB circuit board; its terminal structure is not simplified enough, the number of soldering feet is large, the soldering is troublesome, and the soldering of the smaller soldering feet is not conducive to further controlling the process yield; and the arrangement of multiple terminals in the upper and lower rows of terminals is limited by the standard size of the connector, and the size of each terminal is small, which is difficult to meet the requirements of larger current transmission.

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 the present 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.11 and Fig.12As 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 12PIN 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 12PIN 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 convex parts at the front end to match the hook of the male head. The hook adaptation convex part can be formed integrally by only the plastic part of the tongue 2001 itself, or a metal part can be buried, and a hook adaptation convex part profiling part is designed on the metal part. In this way, the hook adaptation convex profiling part is exposed on the left and right sides of the tongue 2001 as the hook adaptation convex part, or the hook adaptation convex profiling part is correspondingly buried in the plastic hook adaptation convex parts on the left and right sides of the tongue 2001 to form the hook adaptation convex part together.
