In addition, the outer mold 7 is integrally formed at the rear end of the plastic shell 5 and integrally wraps the wire 62 and the metal shielding shell 63, and its assembly structure is more stable.

[0028] Among them, the front end of the plastic shell 5 has a plugging part 51 for inserting into the plugging slot of the board-end TYPE C female socket connector. An elastic locking arm 52 for inserting into the board-end TYPE C female socket connector and locking with the board-end TYPE C female socket connector is integrally formed on the plugging part 51. A rear locking seat 8 that can move back and forth and is used to lock the elastic locking arm 52 to prevent the elastic locking arm 52 from being pressed down is also provided on the plastic shell 5. That is to say, the utility model can insert the elastic locking arm 52 directly into the board-end TYPE C female socket connector and lock with the board-end TYPE C female socket connector, and can lock the elastic locking arm 52 by pushing the rear locking seat 8 forward to prevent the elastic locking arm 52 from being pressed down, so as to achieve the purpose of secondary locking. Its locking effect is excellent, ensuring that the utility model is stably connected to the board-end TYPE C female socket connector, and there will be no accidental detachment. Moreover, the operation is extremely simple and smooth. When unlocking is required, push the rear locking seat 8 backward to unlock the rear locking seat 8 relative to the elastic locking arm 52. At this time, the elastic locking arm 52 can be pressed down.
