Description

Technical Field

[0001] The present invention relates to the field of TYPE-C fast charging female connector technology, and in particular to a TYPE-C14PIN fast charging female connector and electronic products that comply with association standards. 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.
