And the locking protruding portion 16 of the first connector 1 rearwardly snaps into the locking hole 28 of the second connector 2 along the front-rear direction D2. By the cooperation between the locking hook portion 15 and the locking block 26 and the locking recessed groove 27 and the cooperation between the locking protruding portion 16 and the locking hole 28, an effect that the first connector 1 and the second connector 2 can be further locked after the first connector 1 and the second connector 2 mate with each other.

Moreover, at this time, the cover body 242 of the actuator 24 covers the top portion 132 of the first shell 13 of the first connector 1 (see FIG. 1), furthermore, in the present embodiment, the first connector 1 further has a plurality of positioning blocks 17 which are formed to the first housing 11, pass through the first shell 13 and protrude upwardly, the positioning block 17 for example may be formed by hot melting after the first housing 11 and the first shell 13 are assembled with each other, the cover body 242 of the actuator 24 has a plurality of positioning holes 242a which respectively correspond to the plurality of positioning blocks 17. While the actuator 24 rotates to the actuating position, the plurality of positioning holes 242a of the cover body 242 of the actuator 24 respectively receive the plurality of positioning blocks 17 of the first connector 1.

In the above mating process of the first connector 1 and the second connector 2, because only in a latter half of the mating process can the first terminal 122 of the first connector 1 and the second terminal 222 of the second connector 2 contact each other, so in a former half of the mating process, a contact force between the first terminal 122 of the first connector 1 and the second terminal 222 of the second connector 2 is zero. Therefore, the first terminal 122 of the first connector 1 and the second terminal 222 of the second connector 2 can be avoided being damaged due to an improper force applied by a person in the former half of the mating process.

Referring to FIG. 18 to FIG. 20, when the mating needs be released, the actuator 24 is rotated from the actuating position to the non-actuating position, the restoring structure 243 of the actuator 24 forwardly hooks and pushes the pushed structure 14 of the first connector 1 in the front-rear direction D2 to push the first connector 1 forwardly, in turn to make the contacting between the first contact portions 122c, 122e of the first terminals 122 (see FIG. 5) and the second contact portions 222c, 222e of the second terminals 222 (see FIG. 9) released and make the mating of the first connector 1 and the second connector 2 released.

Referring to FIG. 11 and FIG. 12, at this time, the locking hook portion 15 of the first connector 1 is forwardly detached from the locking block 26 of the second connector 2 along the front-rear direction D2, and the tail end of the locking hook portion 15 of the first connector 1 is forwardly withdrawn from the locking recessed groove 27 of the second connector 2 along the front-rear direction D2. And the locking protruding portion 16 of the first connector 1 is forwardly detached from the locking hole 28 of the second connector 2 along the front-rear direction D2, so, after the mating is released, the first connector 1 and the second connector 2 may be separated from each other along the up-down direction D1.

In conclusion, the mating process between the first connector 1 and the second connector 2 of the connector assembly 100 of the present disclosure may be divided into the former half and the latter half, in the former half, the first connector 1 and the second connector 2 move toward each other along the up-down direction D1 (the first direction); in the latter half, the first connector 1 and the second connector 2 move relative to each other along the front-rear direction D2 (the second direction). Because only in the latter half of the mating process can the first terminal 122 of the first connector 1 and the second terminal 222 of the second connector 2 contact each other, so in the former half of the mating process, a contact force between the first terminal 122 of the first connector 1 and the second terminal 222 of the second connector 2 is zero. In addition, the cam portion 241a of the actuator 24 can push the first connector 1 rearwardly in the front-rear direction D2 (the second direction) to make the first connector 1 and the second connector 2 mate with each other, the restoring structure 243 of the actuator 24 can push the first connector 1 forwardly in the front-rear direction D2 (the second direction) to make the mating between the first connector 1 and the second connector 2 released, the locking arm 244 of the actuator 24 can make the actuator 24 held to the actuating position. Moreover, the second contact portion 222c of the second signal terminal 222a of the second terminal 222 of the second connector 2 is constructed to the arc-shaped edge of the second signal terminal 222a and is used to abut against the surface of the first contact portion 122c of the first signal terminal 122a of the first terminal 122, such a contacting manner can increase a contact pressure between the second contact portion 222c and the surface of the first contact portion 122c, and, a contact area between the second contact portion 222c which is constructed to the arc-shaped edge of the second signal terminal 222a and the surface of the first contact portion 122c of the first signal terminal 122a is more stable in size, which can avoid a problem that a contact area with respect to a straight line shaped edge structure is not stable in size (a line-shaped contact region between terminals is prone to be converted into a point-shaped contact region due to rotating of the terminal(s)). Moreover, a stress on the cable 123 can be relieved by the covering structure 112 which is provided to the cable receiving space 111c of the first body 111 and only covers the local part of the cable 123, by the cooperation between the locking hook portion 15 and the locking block 26 and the locking recessed groove 27 and the cooperation between the locking protruding portion 16 and the locking hole 28, an effect that the first connector 1 and the second connector 2 can be locked after the first connector 1 and the second connector 2 mate with each other.

However, what is described above is just the embodiments of the present disclosure, which is not intended to limit the scope implementing the present disclosure, any simple equivalent variations and modifications made according to the claims and the specification of the present disclosure will also be fallen within the scope of the present disclosure.
