[0024] The following combination Figures 1-4 This utility is described in further detail.

[0025] This embodiment discloses a quick connector: comprising a housing, wherein a clamping assembly 2 for quickly connecting a circuit is provided inside the housing;

[0026] The clamping assembly 2 comprises,

[0027] The conductive end 21 is arranged at the center of the inner portion of the housing. The outer wall of the conductive end 21 is rotatably connected to the telescopic rod 22 on both sides. The other end of the telescopic rod 22 is fixedly provided with a support rod 26. The conductive end 21 is provided with a telescopic slot 215 inside. The telescopic slot 215 is slidably connected to the limit block 211.

[0028] A clamping ring 25 slides inside the housing, and the outer side of the clamping ring 25 is fixedly connected to the other end of the support rod 26;

[0029] The conductive pillar 212 has a clamping slot 213 formed on its outer wall. The clamping slots 213 are arranged in an array about the axis of the conductive pillar 212 , and the limiting block 211 is inserted into the clamping slot 213 .

[0030] With such a configuration, the lines can be quickly connected through the clamping assembly 2, preventing the lines from falling off, facilitating one-handed operation, and improving the efficiency of line connection.

[0031] One side of the limit block 211 is in the shape of a "slope", and one side of the slope of the limit block 211 is low in contact with the conductive column 212. When the limit block 211 is inserted into the inside of the clamping groove 213, the slope of one side of the limit block 211 can be used to enable the conductive end 21 to move. After the slope of the limit block 211 is subjected to external force, the limit block 211 moves toward the inside of the telescopic groove 215 until the limit block 211 moves to another clamping groove 213 outside the conductive column 212. The limit block 211 continues to be inserted into the inside of the clamping groove 213, and the right-angled side of the limit block 211 is in contact with the upper end of the inner wall of the clamping groove 213, effectively avoiding the possibility of the conductive end 21 moving upward and preventing the circuit from loosening.

[0032] A protective cover 24 is fixedly provided inside the shell, and a rotating shaft 23 is provided on both sides of the outer wall of the protective cover 24. The support rod 26 is connected to the telescopic rod 22 in a rotational connection with the rotating shaft 23. When the conductive end 21 moves downward, it drives the telescopic rod 22 and the support rod 26 to rotate about the rotating shaft 23, driving the clamping ring 25 to move inward to clamp the line.

[0033] An elastic member 214 is provided inside the telescopic slot 215, and one end of the elastic member 214 is low-connected to one end of the limit block 211, and the other end of the elastic member 214 is low-connected to the bottom end of the telescopic slot 215. By utilizing the elastic force of the elastic member 214, when the limit block 211 moves to the next layer of the clamping slot 213, the limit block 211 continues to be inserted into the inside of the clamping slot 213, thereby achieving clamping with different tightness.

[0034] The clamping ring 25 , the support rod 26 and the telescopic rod 22 are all symmetrically distributed about the axis of the conductive end 21 . The two clamping rings 25 are used to clamp the circuit, making the clamping more stable.

[0035] The clamping ring 25 , the support rod 26 and the telescopic rod 22 are all made of metal. The current of the circuit is guided to the conductive column 212 through the clamping ring 25 to avoid poor contact.

[0036] Two wire entry holes 11 are fixedly provided on both sides of the housing. The two wire entry holes 11 are used to connect the lines at both ends, thereby reducing the number of operation steps.

[0037] The implementation principle of a quick connector in the embodiment of the present application is as follows: the line is extended into the interior of the shell from the entry hole, and after the wire core contacts the conductive end 21, the conductive end 21 is pushed to move downward. While the conductive end 21 moves, it can drive the telescopic rod 22 and the support rod 26 to rotate about the rotating shaft 23, so that the clamping ring 25 moves inward to clamp the wire core. At the same time, when the conductive end 21 moves downward and the limit block 211 is inserted into the inside of the clamping groove 213, the inclined surface on one side of the limit block 211 can be used to enable the conductive end 21 to move. After the inclined surface of the limit block 211 is subjected to external force, the limit block 211 moves toward the inside of the telescopic groove 215 until the limit block 211 moves to another clamping groove 213 outside the conductive column 212. The limit block 211 continues to be inserted into the inside of the clamping groove 213, and the right-angled side of the limit block 211 is in contact with the upper end of the inner wall of the clamping groove 213, effectively avoiding the possibility of the conductive end 21 moving upward and preventing the line from loosening.

[0038] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
