[0025] The technical solutions of this utility model will be further described below in conjunction with the attached drawings and through specific implementation manners.

[0026] Such as Figures 1 to 3As shown, an embodiment of the utility model provides a secondary locking structure of a connector, comprising a male connection part 10, a secondary locking member 20 and a female connection part 30, wherein the male connection part 10 is connected to the female connection part 30 by locking; the secondary locking member 20 can be rotatably connected to the male connection part 10, and the secondary locking member 20 is used to press the female connection part 30 onto the male connection part 10; when the male connection part 10 and the female connection part 30 are initially locked, the secondary locking member 20 can press the female connection part 30 onto the male connection part 10 by rotating, thereby increasing the locking force between the female connection part 30 and the male connection part 10 to prevent the connection from loosening or falling off.

[0027] Baffles 101 are provided on both sides of the male connection part 10, an insertion channel 102 is provided between the baffles 101, an insertion port 103 is provided in the insertion channel 102, and the insertion port 103 is used to be plugged and connected with the female connection part 30, a connecting hole 104 is provided at the end of the baffle 101, a rotating column 201 is provided at the bottom of the secondary locking member 20, the rotating column 201 is sleeved in the connecting hole 104, and the rotating column 201 can rotate around the connecting hole 104, a pressing plate 202 abutting against the female connection part 30 is provided at the bottom of the secondary locking member 20, a locking groove 105 is provided on the side wall of the baffle 101 between the insertion port 103 and the connecting hole 104, and locking blocks 203 extending horizontally outward are respectively provided on both sides of the top of the secondary locking member 20, and the locking blocks 203 are used to be connected or unlocked with the locking groove 105 through locking as the rotating column 201 rotates. The male connection part 10 and the female connection part 30 can be preliminarily connected through the plug interface 103. The user can rotate the locking block 203 into the locking groove 105 to lock it by rotating the secondary locking member 20. When the locking block 203 of the secondary locking member 20 is completely inserted into the locking groove 105 and the pressure plate 202 abuts against the surface of the female connection part 30, the connector is in the secondary locking state. At this time, the male connection part 10 and the female connection part 30 are firmly locked together to ensure the stability and reliability of the connection; when unlocking is required, only the secondary locking member 20 needs to be rotated in the opposite direction to disengage the locking block 203 from the locking groove 105. At this time, the pressure plate 202 is separated from the female connection part 30, and the clamping state is released, thereby realizing the separation of the male connection part 10 and the female connection part 30, which is convenient for unlocking.

[0028] like Figure 1 As shown, further, an arc-shaped groove structure 204 is provided on the top of the secondary locking member 20 for easy finger movement. The arc-shaped groove structure 204 is adapted to the shape of the finger, so that the user can easily use the finger to move the secondary locking member 20 to rotate, and the locking and unlocking operations can be conveniently performed even without tools.

[0029] likeFigure 1 As shown, further, a guiding sliding groove 106 is provided on the side wall of the end portion of the baffle 101. The guiding sliding groove 106 is used for the locking block 203 to slide into and rotate into the locking groove 105 to achieve locking. The setting of the guiding sliding groove 106 makes the sliding and locking process of the secondary locking member 20 smoother and more seamless, avoiding misalignment or jamming, and enhancing the user experience.

[0030] As Figure 1 and Figure 3 shown, further, a limiting protrusion 205 is provided on the side wall of the secondary locking member 20 close to the insertion interface 103. The limiting protrusion 205 is used for limiting abutting connection with the side wall of the locking groove 105 to limit the rotation angle of the secondary locking member 20. The setting of the limiting protrusion 205 can prevent damage to the connector or the secondary locking member 20 caused by excessive rotation during the operation of the user, improving the safety of the operation and the durability of the connector.

[0031] As Figure 1 shown, further, the shape of the locking block 203 is a trapezoidal structure. The setting of the trapezoidal structure makes the process of the locking block 203 sliding into and out of the locking groove 105 smoother, reducing the operation resistance. And after the locking block 203 is completely inserted into the locking groove 105, the inclined surfaces on both sides of the locking block 203 will be in close contact with the inner wall of the locking groove 105, thereby preventing loosening or falling off in a vibration or impact environment.

[0032] Further, the width of the locking groove 105 is greater than the width of the locking block 203. The relatively wide locking groove 105 enables the locking block 203 to have a certain self-aligning ability during the insertion process. Even if it is not completely aligned in the initial position, the locking block 203 can adjust its position by itself during the process of sliding into the locking groove 105, thereby achieving rapid locking.

[0033] Further, the depth of the locking groove 105 is 2 - 4 mm. In this embodiment, the depth of the locking groove 105 is 3 mm. When the depth of the locking groove 105 is too large, it will cause the locking block 203 to require a greater force during the locking operation, increasing the operation difficulty. At the same time, an overly deep locking groove 105 will also make it difficult to pull out the locking block 203, affecting the convenience of the unlocking operation. When the depth of the locking groove 105 is too small, the embedding depth of the locking block 203 in the groove is insufficient, resulting in insufficient locking force, easily causing connection looseness or insecure locking, and making it difficult to achieve a stable connection.

[0034] The male connection part 10 and the female connection part 30 of the present utility model can be preliminarily connected. The user can rotate the secondary locking part 20 to rotate the locking block 203 into the locking groove 105 for locking. When the locking block 203 of the secondary locking part 20 is completely inserted into the locking groove 105 and the pressing plate 202 abuts against the surface of the female connection part 30, the connector is in the secondary locking state. At this time, the male connection part 10 and the female connection part 30 are firmly locked together to ensure the stability and reliability of the connection and prevent the connection from loosening or falling off. When unlocking is required, just rotate the secondary locking part 20 in the reverse direction to make the locking block 203 disengage from the locking groove 105. At this time, the pressing plate 202 is separated from the female connection part 30, and then the pressing state is released, so as to realize the separation of the male connection part 10 and the female connection part 30, which is convenient for unlocking.

[0035] As mentioned above, the above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model.
