The connector assembly according to claim 10, wherein, Further comprising: A mating connector (2), including: A mating connector housing (20); And The terminal (200) is disposed in the mating connector housing (20). The connector (1) is mated into the mating connector housing (20), and the terminal (200) of the mating connector (2) is in electrical contact with the circuit board (100) of the connector (1).

12. The connector assembly according to claim 11, wherein: Columnar protrusions (14) are respectively formed on the outer sides of two laterally opposite side walls of the connector housing (10), and arc-shaped grooves (24) are respectively formed on two laterally opposite side walls of the mating connector housing (20). The columnar protrusions (14) are assembled into the arc-shaped grooves (24) such that the connector (1) can be opened and closed rotatably relative to the mating connector (2) about the axis of the columnar protrusions (14). When the connector locking member (3) is in the pre-locked position, the connector (1) can be opened and closed rotatably relative to the mating connector (2). When the connector locking member (3) is in the final locked position, the connector locking member (3) locks the connector (1) in the closed position such that the connector (1) and the mating connector (2) are held in the mated state.

13. The connector assembly according to claim 12, wherein: Limiting steps (22c) are respectively formed on the inner sides of two laterally opposite side walls of the mating connector housing (20). When the connector locking member (3) is in the pre-locked position, the limiting steps (22c) abut against the rear side of the limiting protrusions (32c) of the connector locking member (3) along the longitudinal direction (Y) to pre-lock the connector locking member (3) to the mating connector housing (20).

14. The connector assembly according to claim 13, wherein: A pair of jacks (22) are formed on the front wall of the mating connector housing (20), and a protrusion (22b) is formed on the inner side of the jacks (22). When the connector locking member (3) is in the final locked position, the elastic arms (32) of the connector locking member (3) are inserted into the jacks (22), and the second protrusions (32b) on the elastic arms (32) engage with the protrusions (22b) inside the jacks (22) to lock the connector locking member (3) to the mating connector housing (20). When the connector locking member (3) is locked to the mating connector housing (20), the connector locking member (3) locks the connector (1) in the closed position to prevent the connector (1) from being accidentally moved to the open position.

15. The connector assembly according to claim 14, wherein: Slots (23) are respectively formed on the inner sides of two side walls of the mating connector housing (20), and the slots (23) extend along the longitudinal direction (Y). When the connector locking member (3) is in the final locking position, the tongue (33) on the connector locking member (3) is inserted into the slot (23) in an interference fit manner to lock the connector locking member (3) to the mating connector housing (20).

16. The connector assembly according to claim 15, wherein: The arc-shaped groove (24) is formed at the front end of the side wall of the mating connector housing (20) and close to the front wall of the mating connector housing (20), and the slot (23) is formed at the rear end of the side wall of the mating connector housing (20).

17. The connector assembly according to any one of claims 9-16, wherein: The cross-sections of the sliding groove (31) and the sliding rail (11) are in the shape of a dovetail.
