[0039] Specifically, one end of the housing 1 is provided with a plurality of mounting holes 11, and a plurality of terminals 4 are respectively provided with a plurality of mounting holes 11. The other end of the housing 1 is provided with an opening 12. The plug-in 2 is disposed inside the housing 1 and close to the opening 12. The plug-in 2 is provided with a plurality of grooves 21, and the grooves 21 are respectively provided with a plurality of mounting holes 11. The locking member 3 is disposed between one end of the housing 1 and the plug-in 2, and the locking member 3 is slidably disposed on the plug-in 2 so that the locking member 3 has a locked position and an unlocked position. The terminals 4 pass through the mounting holes 11 and the locking member 3 in sequence and are disposed in the grooves 21. The locking member 3 is used to lock or unlock the terminals 4. Compared with the prior art, this female connector, by placing the locking member 3 between the housing 1 and the plug-in 2, can improve the holding force of the locking member 3, prevent the locking member 3 from falling off, lock the terminals 4, and improve the connector mating efficiency. It should be noted that the sliding direction of the locking member 3 is perpendicular to the insertion direction of the female connector.

[0040] Optionally, the connector 2 is provided with locking grooves 22 and unlocking grooves 23 at intervals, and the locking member 3 is provided with protrusions 31. When the locking member 3 is in the locked position, the protrusions 31 are inserted into the locking grooves 22, and when the locking member 3 is in the unlocked position, the protrusions 31 are inserted into the unlocking grooves 23. Specifically, the two opposite sidewalls of the connector 2 are provided with locking grooves 22 and unlocking grooves 23 at intervals, and the two corresponding sidewalls of the locking member 3 are provided with protrusions 31, which can realize the switching of the locking member 3 between the locked position and the unlocked position, so as to lock or unlock the terminal 4.

[0041] Optionally, the locking member 3 is provided with a plurality of locking holes 32, and the plurality of locking holes 32 are provided in a one-to-one correspondence with a plurality of terminals 4. The terminals 4 are provided with locking grooves 41, and the terminals 4 pass through the locking holes 32. When the locking member 3 is in the locked position, the hole wall of the locking hole 32 is inserted into the locking groove 41 to achieve a one-time locking of the terminal 4 and prevent the terminal 4 from moving. When the locking member 3 is in the unlocked position, the hole wall of the locking hole 32 is pulled out of the locking groove 41.

[0042] Optionally, the housing 1 includes an inner shell 13 and an outer shell 14. The connector 2 is snapped into the inner shell 13, and the locking member 3 is slidably sleeved on the inner shell 13. The connector 2 is slidably sleeved on the locking member 3, so that the locking member 3 can have a locked position and an unlocked position relative to the connector 2. Specifically, the housing 1 is U-shaped, the connector 2 is provided with a buckle, and the inner shell 13 is provided with a slot. The buckle can be snapped into the slot to achieve a fixed connection between the connector 2 and the inner shell 13, so that the locking member 3 can have a locked position and an unlocked position relative to the connector 2 and the housing 1.

[0043] Optionally, the inner shell 13 is provided with a plurality of locking blocks 131, which are respectively arranged in correspondence with a plurality of terminals 4.

The riveting portion 42 is connected to one end of the main body 43, and the other end of the main body 43 is provided with a first insertion hole 44. The riveting direction of the riveting portion 42 is arranged along the length direction of the first insertion hole 44. With this arrangement, compared with the prior art, rotating the riveting direction of the riveting portion 42 by 90° can prevent the terminal 4 from bending under force during the riveting process and avoid the first insertion hole 44 from being eccentric.

[0046] Furthermore, the connector 2 is provided with a plurality of second insertion holes 24, each corresponding to a plurality of terminals 4, with the second insertion holes 24 facing the first insertion holes 44. Specifically, the terminals 4 are provided with a first error-proof structure 45, and the connector 2 is provided with a second error-proof structure. The first error-proof structure 45 and the second error-proof structure cooperate to prevent the terminals 4 from rotating or being installed in the wrong direction, ensuring that the second insertion holes 24 are facing the first insertion holes 44.
