DETAILED DESCRIPTION

[0025] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0026] like Figure 1 and Figure 2 The embodiment of the utility model shown in the figure comprises: a female connector 1, a male connector 2 and a U-shaped rotating handle 3, wherein the U-shaped rotating handle 3 comprises: a wide support leg 301, a push handle portion 302, a locking portion 304 and a locking column sliding groove 303, wherein the push handle portion 302 is provided with a wide support leg 301 at both ends in the same direction, the locking portion 304 is provided at the center of the push handle portion 302, and the locking portion 304 matches with the buckle 101 on the female connector 1 to form a snap connection; the two wide support legs 301, the push handle portion 302 and the locking portion 304 are integrally fixedly connected, a locking column sliding groove 303 is provided on the wide support leg 301, the two locking column sliding grooves 303 have the same trajectory, and the outer end of the locking column sliding groove 303 is provided with a straight track portion 3031 for aligning the locking column 210;

[0027] A locking column 210 is provided on both sides of the male connector 2, and the axes of the two locking columns 210 are collinear. The two collinear locking columns 210 cooperate with the locking column sliding groove 303 of the U-shaped rotating handle 3, and the female connector 1 and the male connector 2 are gradually locked as the U-shaped rotating handle 3 rotates.

[0028] In this embodiment, the flange screw hole 220 at the end of the male connector 2 is directly injection molded, replacing the nut that is conventionally inserted during later installation; this makes it easier to operate the male connector 2 and the mounting plate through threaded connection, and increases air tightness and water tightness.

[0029] A clamping locking member group 110 is installed on the side wall of the female connector 1, and a shaft 120 is installed on the side walls on both sides of the female connector 1. A shaft 120 is inserted into the middle hole of the wide legs 301 on both sides of the U-shaped rotating handle 3 to form a rotation connection, so that the U-shaped rotating handle 3 can rotate freely relative to the female connector 1 within the collision range. When locked, the locking part 304 of the U-shaped rotating handle 3 is clamped with the clamping locking member group 110, so that the two connectors remain locked and will not be loosened;

[0030] The snap-fit ​​locking component group 110 includes: a snap 111, a snap-fit ​​mounting column 112 and a snap-fit ​​top plate 113, wherein the first end of the snap-fit ​​mounting column 112 is integrally fixed to the side wall of the female connector 1, the second end of the snap-fit ​​mounting column 112 is integrally fixed to the root of the snap 111, and the end of the snap 111 is snapped with the locking portion 304; a sliding snap-fit ​​top plate 113 is provided below the snap 111, and after the snap-fit ​​top plate 113 is pushed to the head, it is located below the snap 111 to prevent the snap 111 from being pressed downward, thereby maintaining the snap connection between the snap 111 and the locking portion 304.

[0031] In this embodiment, in order to facilitate the pushing and pulling of the snap-on top plate 113, a horizontal bar 114 is provided at the end of the snap-on top plate 113; in particular, in order to maintain stability, a snap-on top plate 113 is also provided at the other end of the horizontal bar 114. When locking, the two snap-on top plates 113 are simultaneously pushed to the bottom of the snap 111, playing the role of a secondary lock.

[0032] In this embodiment, two buckle mounting posts 112 are provided at the same time, and there is a certain space between the two parallel buckle mounting posts 112. This hollow design increases the elasticity of the buckle and makes the buckle 111 easier to press.

[0033] In this embodiment, in order to protect the buckle 111 from being damaged by collision, buckle protection side walls 1111 are provided on both sides of the buckle 111, and the buckle protection side walls 1111 prevent the buckle 111 from being structurally damaged due to side impact; in particular, in order to ensure the strength of the buckle protection side walls 1111, side wall reinforcement ribs 11111 are provided on the extension line of the non-buckle connection end (distal end) of the buckle protection side walls 1111, and the distal end size of the side wall reinforcement ribs 11111 exceeds the position of the buckle 111 and the buckle mounting column 112, so that the buckle 111 and the buckle mounting column 112 can also be protected when they are hit in multiple directions;

[0034] In this embodiment, in order to maintain the push-pull direction of the buckle top plate 113, a top plate slide groove 11112 is provided on the buckle protection side wall 1111; in particular, in order to ensure the strength of the side wall reinforcement rib 11111, the thickness of the side wall reinforcement rib 11111 is close to the thickness of the buckle protection side wall 1111, and therefore the top plate slide groove 11112 also extends to the side wall reinforcement rib 11111.

[0035] When the female connector 1 and the male connector 2 need to be assembled, first rotate the U-shaped rotating handle 3 to make the outer end of the locking column sliding groove 303 face the locking column 210 of the male connector 2 as the initial position; at the same time, pull out the buckle top plate 113 to complete the preparation work;

[0036] Then, the female connector 1 and the male connector 2 are inserted together, and the two locking posts 210 are inserted into the corresponding locking post sliding grooves 303;

[0037] Then, the U-shaped rotating handle 3 is rotated from the initial rotating position, the locking column 210 moves in the locking column sliding groove 303, and the matching female connector 1 and the male connector 2 continue to move toward each other so that each core is connected and the low-voltage signal is electrically connected;

[0038] When the U-shaped rotating handle 3 reaches the rotation completion position, the protection buckle 111 and the locking portion 304 are engaged to keep the U-shaped rotating handle 3 at the rotation completion position;

[0039] Finally, push in the buckle top plate 113, which supports the buckle 111 from below so that the buckle 111 cannot move downward, and the assembly is completed.

[0040] When the female connector 1 and the male connector 2 need to be opened, pull out the buckle top plate 113, squeeze the buckle 111 downward, and pop the locking portion 304 out of the locking position, and rotate the U-shaped rotating handle 3 to the initial position; pull apart the female connector 1 and the male connector 2 to complete the disconnection.
