The lock sleeve 2 and the unlocking sleeve 3 are linked and respectively play their roles, so that the structural design of the lock sleeve and the unlocking sleeve is simpler, the preparation process of the electric connector is simplified, and the cost is reduced.

The following further exemplary description is made with respect to the structure of the components involved in the electrical connector and their function, respectively:

as shown in fig. 4, the first locking piece 21 includes a first inclined surface 210, the first inclined surface 210 is inclined and extends along the axial direction of the unlocking sleeve 3, and the second locking piece 201 includes: a second inclined surface 2010, the second inclined surface 2010 being inclined and extending along an axial direction of the female end 200. The first inclined surface 210 is slidably engaged with the second inclined surface 2010, so that the first locking piece 21 is driven to rotate by the second locking piece 201.

In some examples, as shown in fig. 4, the first lock block 21 includes: the first locking main body section 211 and the first locking section 212, the first locking section 212 is located on one side of the first locking main body section 211, and the first locking section 212 and the first locking main body section 211 are matched to form a first locking groove 213, wherein the first inclined surface 210 is located on one side of the first locking section 212, which is away from the first locking main body section 211.

As shown in fig. 4, the second locking piece 201 includes: the second locking main body segment 2011 and the second locking segment 2012 are connected to one side of the second locking main body segment 2011, and the second locking segment 2012 and the second locking main body segment 2011 are matched to form a second locking groove 2013, wherein the second inclined surface 2010 is located on one side of the second locking segment 2012, which is away from the second locking main body segment 2011.

When the first locking piece 21 is locked to the second locking piece 201, the first locking segment 212 is limited to the second locking groove 2013, and the second locking segment 2012 is limited to the first locking groove 213.

For example, the first locking body section 211 and the first locking section 212 are arc-shaped protrusions, and the arc degree of the first locking body section and the arc-shaped protrusions is consistent with the arc degree of the annular inner wall of the lock sleeve 2. Correspondingly, the second locking main body segment 2011 and the second locking segment 2012 are also arc-shaped protrusions, and the radian of the second locking main body segment 2011 and the radian of the second locking main body segment 2012 are consistent with the radian of the annular inner wall of the female end 200.

The first inclined surface 210 has an inclined length sufficient to ensure that the male end 100 is rotated to a corresponding limit position when the male end 100 is inserted into position. The second inclined surface 2010 has an inclined length sufficient to effectively and easily drive the first inclined surface 210 to rotate.

In some examples, the inclined length of the first inclined surface 210 is greater than that of the second inclined surface 2010, for example, the inclined length of the first inclined surface 210 extends from one end of the first locking segment 212 to the other end thereof, and the inclined length of the second inclined surface 2010 may be designed only at the corresponding end of the second locking segment 2012.
