[0030] See also Figure 1-Figure 7 The utility model provides a technical solution: a high-stability cable connection butt plug, comprising a first cable 1, a first shell 2 arranged at the upper end of the first cable 1, a first conductor 3 arranged inside the first shell 2, a second shell 4 arranged above the first shell 2, a second conductor 5 arranged inside the second shell 4, a second cable 6 arranged at the upper end of the second shell 4, a rotating mechanism 7 is arranged on the inner wall of the first shell 2, and a limiting mechanism 8 is arranged below the rotating mechanism 7;

[0031] The limiting mechanism 8 includes a buckle assembly 81 and an elastic assembly 82, and the elastic assembly 82 is arranged above the buckle assembly 81;

[0032] The rotating mechanism 7 includes a first rotating ring 701 arranged on the inner side of the first housing 2, a first groove 702 is connected on the lower inner wall of the first housing 2, a second rotating ring 703 is arranged on the inner side of the first groove 702, the outer side surface of the second rotating ring 703 is in contact with the inner side surface of the first groove 702, and the outer side structure of the second rotating ring 703 is circular, so that the second rotating ring 703 rotates inside the first groove 702 without swinging up and down and moving out of the first groove 702. 03 is connected to the first rotating ring 701 in a fixed connection, so that the first rotating ring 701 can only rotate and will not move up and down. The upper inner wall of the first housing 2 is connected with a second groove 704, and a first baffle 705 is arranged on the inner side of the second groove 704. The first baffle 705 is connected to the first rotating ring 701 in a fixed connection. The appearance structure of the first baffle 705 is an arc shape, and the width of the second groove 704 is greater than the width of the first baffle 705, so that the first rotating ring 701 can drive the The first baffle plate 705 rotates, and the rotation of the first baffle plate 705 has a certain distance. A first guide groove 706 is connected to the inner wall of one side of the second rotating ring 703. The lower part of the first guide groove 706 is connected to the second guide groove 707. A guide rod 708 is arranged on the inner side of the first guide groove 706. The appearance structure of the first guide groove 706 is spiral, and the width of the first guide groove 706 is greater than the width of the guide rod 708, so that the guide rod 708 can follow the trajectory of the first guide groove 706 when moving downward, and push the guide rod 708 to move downward. The first rotating ring 701 rotates, and the guide rod 708 can rotate inside the guide rod 708. A first torsion spring 709 is fixedly connected to the outer side of the lower end of the first rotating ring 701. A second baffle 710 is fixedly connected to the outer side of the lower end of the first rotating ring 701. The appearance structure of the second guide groove 707 is a vertical straight line, and the width of the second guide groove 707 is greater than the width of the guide rod 708, so that when the guide rod 708 moves on the inner side of the second guide groove 707, it will not drive the first rotating ring 701 to rotate.

[0033] The lower surface of the first rotating ring 701 is connected to the third groove 9, and the upper part of the third groove 9 is connected to the limiting groove 10. The buckle assembly 81 includes a limiting rod 8101 arranged on the inner side of the limiting groove 10. The limiting grooves 10 are equidistantly distributed above the third groove 9, and the limiting grooves 10 and the limiting rod 8101 are matched in a clearance fit, so that the limiting rod 8101 can move to the inner side of the limiting groove 10 and be limited. A first hole 8102 is provided on one side of the third groove 9, and the upper side surface of the first hole 8102 is connected to the fourth groove 8103, and the lower surface of the fourth groove 8103 is an inclined surface, and the width of the fourth groove 8103 is greater than the limiting rod 8101, so that the limiting rod 8101 can rotate inside the limiting rod 8101.

[0034] The elastic component 82 includes a third rotating ring 8201 fixedly connected to the inner end of the limiting rod 8101, so that the third rotating ring 8201 can drive the limiting rod 8101 to move up and down when it moves up and down. The third rotating ring 8201 is connected to the guide rod 708 in a fixed manner, so that the third rotating ring 8201 drives the guide rod 708 to move up and down when it moves up and down. A sixth groove 8202 is arranged inside the third rotating ring 8201, and a spring 8203 is arranged inside the sixth groove 8202. A push rod 8204 is fixedly connected to the lower end of the spring 8203, and a third baffle 8205 is fixedly connected to the lower end of the push rod 8204. A fifth groove 8206 is arranged inside the second housing 4, and a fourth rotating ring 8207 is arranged inside the fifth groove 8206. The fourth rotating ring 8207 and the third rotating ring 8 The connection method of 201 is a fixed connection, so that when the fourth rotating ring 8207 rotates, it can drive the third rotating ring 8201 to rotate. The upper end of the third rotating ring 8201 is fixedly connected with a second torsion spring 8208. The second torsion spring 8208 is connected to the second shell 4 in a fixed connection, so that when the second torsion spring 8208 rotates, it can be subjected to force at the second shell 4. The torque of the second torsion spring 8208 is greater than the torque of the first torsion spring 709, so that when the second torsion spring 8208 rotates, the first torsion spring 709 can be rotated, but when the first torsion spring 709 rotates, it will not drive the second torsion spring 8208 to rotate. The outer surface of the third rotating ring 8201 is in contact with the inner surface of the second rotating ring 703, so that the third rotating ring 8201 can rotate on the inner side of the second rotating ring 703 without shaking.

[0035] During installation, the second baffle 710 and the third baffle 8205 of the first conductor 3 and the second conductor 5 need to be opened. The specific operation is as follows:

[0036] The guide rod 708 is aligned with the notch of the first guide groove 706, and the second housing 4 is pushed downward to drive the third rotating ring 8201 and the fourth rotating ring 8207 arranged inside the fifth groove 8206 to move downward. Since the connection between the guide rod 708 and the third rotating ring 8201 is a fixed connection, the guide rod 708 also moves with it. Since the appearance structure of the first guide groove 706 is spiral, when the guide rod 708 moves downward, it can push the first rotating ring along the trajectory of the first guide groove 706. 701 rotates, because the connection mode of the first rotating ring 701 and the second baffle 710 is fixed connection, the second baffle 710 will also rotate, thereby opening the entrance of the first conductor 3, because the connection mode of the first rotating ring 701 and the first torsion spring 709 is fixed connection, the first torsion spring 709 rotates to store force, and because the torque of the second torsion spring 8208 is greater than the torque of the first torsion spring 709, the second torsion spring 8208 will not rotate and be stressed at this time, and when the first rotating ring 701 rotates, the first baffle 705 and the first torsion spring 709 are connected. The connection mode of the rotating ring 701 is a fixed connection, which drives the first baffle 705 to rotate. When the first baffle 705 reaches the edge of the second groove 704, the first baffle 705 and the first rotating ring 701 are blocked and cannot rotate. At this time, the guide rod 708 will continue to move downward. Since the first baffle 705 and the first rotating ring 701 cannot rotate, the guide rod 708 will push the third rotating ring 8201 to rotate, so that the second torsion spring 8208 is rotated and subjected to force. Since the push rod 8204 is set in the sixth groove 8202 On the inner side, the push rod 8204 and the third baffle 8205 are connected in a fixed manner, so that the push rod 8204 and the third baffle 8205 also rotate accordingly to open the output port of the second conductor 5. After the first conductor 3 and the second conductor 5 are separated, the first torsion spring 709 and the second torsion spring 8208 will respectively drive the first rotating ring 701 and the third rotating ring 8201 to perform reset rotation to complete automatic opening and automatic closing, which can prevent the first cable 1 and the second cable 6 from forgetting to close the contact port, thereby causing poor contact.

[0037] After opening the second baffle 710 and the third baffle 8205 of the first conductor 3 and the second conductor 5, it is necessary to connect the first conductor 3 and the second conductor 5 together to reduce the possibility of disconnection due to accident. The specific operation is as follows:

[0038] When the third rotating ring 8201 moves downward, it drives the limiting rod 8101 fixedly connected to the outer side of the third rotating ring 8201 to move downward. When the guide rod 708 moves to the inside of the second guide groove 707, it moves linearly downward, so that the limiting rod 8101 also moves linearly downward inside the first hole 8102. Because the width of the second guide groove 707 is greater than the width of the guide rod 708, rotating the third rotating ring 8201 can drive the guide rod 708 and the limiting rod 8101 to rotate, thereby causing the limiting rod 8101 to rotate linearly. 101 can move to the inside of the third groove 9, loosen the third rotating ring 8201 so that the third rotating ring 8201 moves upward under the action of the spring 8203, so that the third rotating ring 8201 is reset. At this time, the limiting rod 8101 moves to the limiting groove 10, so that the third rotating ring 8201 is limited, completing the connection between the first conductor 3 and the second conductor 5. When disassembling, it is necessary to push the third rotating ring 8201 and rotate the third rotating ring 8201 to complete the disassembly, reducing the possibility of disconnection due to accidental touch.

[0039] Under the reset action of the first torsion spring 709 and the second torsion spring 8208, the third rotating ring 8201 has a rotational force. Even if the third rotating ring 8201 is accidentally pushed and rotated to a certain angle, the rotational force of the third rotating ring 8201 will drive the limit rod 8101 to complete the reset, thereby reducing the possibility of disconnection due to accidents.
