The terminal assembly 3 is composed of terminal A and terminal B. Terminal A is designed with an 8-pin contact portion and a soldered 6-pin lead. A connecting element in the middle connects the power pins (A4 / A9) together to lead out one VBUS pin. The bending of the A1 / A4 / A9 / A12 heads of terminal A allows for more stable and reliable contact between the GND and VBUS terminals after assembly of the upper / lower rows of terminals. The pins of terminal A are sequentially GND / A4 / A9 / A12. The connector has four pins: TX1+, TX1-, VBUS, VBUS, RX1-, RX1+, and GND. Terminal A has a reserved space in the middle for the combination terminal B. Terminal B has four pins: CC1, D+, D-, SBU1, and the function pin. The pin structure of terminals A and B can be designed in three ways: right S-shaped pin, left S-shaped pin, and left-right shaped pin, which enhances the practicality of the connector.

[0019] Furthermore, the inner side of the metal shell 1 is provided with a shell grounding flat 11, which can be inserted and contacted with the EMC spring of the TYPE-C male connector to provide a grounding shielding effect.

The middle clamping piece is in close contact with the GND terminal of the terminal, and the heads of the upper and lower rows of terminals are also bent and in close contact. Then, a second molding process is performed to form the plastic body 2, which has a total of 24 pins in the upper and lower rows, with 20 pins forming a single row of SMT connectors. The plastic body 2 is then assembled into a metal shell. The inner side of the metal shell has an EMC grounding plate that can be plugged into a TYPE-C male connector to achieve grounding shielding. This completes the connector manufacturing process and enables TYPE-C data transmission. The above describes the complete working principle of this utility model.
