Referring to fig. 2 to 5, when the user plugs the plug connector 3 into the receptacle connector 2, one end of the plug metal terminal 34 of the plug connector 3 extends into the receptacle accommodating space 221 through the receptacle plug interface 220 and contacts with one end of the receptacle metal terminals 24 to exchange signals or currents with each other, so that the receptacle plug part 21 and the plug part 31 can form an electrical connection, each of the locking parts 23 is assembled to each of the corresponding first locking units 33 (e.g., embedded into the first opening 331) to form a locking structure, and the embedding part 25 is assembled to the second locking unit 35 (e.g., embedded into the second opening 351) to form a locking structure.

Referring to fig. 2 and 6, the sliding locking frame 4 is sleeved on the plug connector 3 (as shown in fig. 5), the left and right sides thereof are respectively provided with a pushing unit 41, and each pushing unit 41 is located at the inner side of each corresponding first locking unit 33, and then when a user wants to take off the plug connector 3, the user can firstly displace the sliding locking frame 4 toward the top side of the plug connector 3 (as shown in fig. 7), so that each pushing unit 41 can open the corresponding first locking unit 33 outwards, and each first locking unit 33 is separated from the corresponding buckling portion 23, so as to form an unlocking state (as shown in fig. 8); in this embodiment, to facilitate the abutting unit 41 to open the first locking unit 33, the inner wall of the first locking unit 33 is provided with a first abutting inclined surface 333, and the outer wall of the abutting unit 41 is provided with an abutting inclined surface 411, as shown in fig. 8, when the sliding locking frame 4 is displaced toward the top side of the plug connector 3 (as shown by the arrow of the dotted line in fig. 8), each abutting inclined surface 411 abuts against the corresponding first abutting inclined surface 333 and moves along each first abutting inclined surface 333, so that the first locking unit 33 can be more easily opened outward, and the first locking unit 33 is separated from the locking portion 23 to form the unlocking state.

Thereafter, referring to fig. 2 and fig. 6, the user can press the area of the second locking unit 35 near the top end inwards (as shown by the dotted arrow in fig. 9) to disengage the second locking unit 35 from the engaging portion 25 to form an unlocked state (as shown in fig. 9), wherein the sliding locking frame 4 is omitted in fig. 9 to clearly show the unlocked state, but in practical use, the sliding locking frame 4 is still located on the plug connector 3, so that the user can remove the plug connector 3 and the sliding locking frame 4 together. In addition, in other embodiments of the present disclosure, not only the unlocking sequence of the foregoing embodiments is limited, but also the second locking unit 35 can be unlocked first and then the sliding locking frame 4 can be moved to perform subsequent unlocking according to different designs of products. In summary, since the sliding locking frame 4 of the present disclosure can simultaneously open the two first locking units 33 when moving toward the top side of the plug connector 3, there is no situation that one locking portion completes unlocking and the other locking portion does not unlock as in the conventional locking portions, and therefore, a user can clearly determine whether the unlocking state is completed by pulling the hand feeling of the sliding locking frame 4, so as to reduce the probability that the plug connector 3 or the receptacle connector 2 is damaged due to hard pulling of the plug connector 3 by the user.

In addition, in order to improve the convenience of the user moving the sliding lock frame 4, as shown in fig. 2 and fig. 5, the sliding lock frame 4 is provided with a pulling portion 43 on each of the left and right sides thereof, and each pulling portion 43 is located outside each first locking unit 33, so that the user's finger can apply force to each pulling portion 43 to pull the sliding lock frame 4 upward. It is stated here that although the slide lock frame 4 is drawn in the present disclosure as an integrally formed form, in other embodiments of the present disclosure, the slide lock frame 4 can be combined by a plurality of components as long as it can simultaneously accomplish the corresponding unlocked states to the two first locking units 33 when it is operated.

Besides, besides the hand feeling of pulling the sliding lock frame 4, the connector set can be further provided with at least one locking member 5 to prevent the user from pressing the second locking unit 35 forcefully and removing the plug connector 3 when the unlocking state corresponding to the first locking unit 33 is not completed, as shown in fig. 2 and 5, the locking member 5 is movably located inside the second locking unit 35 and corresponds to the position of the second locking unit 35 near the top end, the front side of the sliding lock frame 4 is provided with at least one driving unit 45, the driving unit 45 is connected with the locking member 5 and can drive the locking member 5 to move up and down, for example, in the embodiment, the front side of the locking member 5 is convexly provided with a convex pillar 51, the driving unit 45 is provided with an opening, and the convex pillar 51 can extend into the opening, when the sliding lock frame 4 moves toward the top side of the plug connector 3, the driving unit 45 drives the locking member 5 to move upward, so that the locking member 5 is separated from the position corresponding to the second locking unit 35, and the region of the second locking unit 35 adjacent to the top end can be pressed inward (as shown in fig. 9), so that the second locking unit 35 is separated from the engaging portion 25, thereby forming an unlocking state. Thus, when the user pulls the sliding locking frame 4, but the pulling distance is too short, so that the first locking unit 33 cannot be reliably separated from the buckling part 23, the local area of the second locking unit 35 still can correspond to the inner side of the second locking unit 35, so that the user cannot press the second locking unit 35, and at this time, the user can know that the current unlocking state is not reliable enough, thereby effectively reducing the damage rate of the connector set.

The above description is only a preferred embodiment of the present disclosure, and the protection scope of the present disclosure is not limited thereto, and all persons skilled in the art can easily consider equivalent changes based on the technical content disclosed in the present disclosure, and the protection scope of the present disclosure should not be left.
