[0036] See also Figure 1-6 As shown, a spiral line assembly, the spiral line assembly comprises:

[0037] A spiral cable 1, with terminals 2 fixedly connected at both ends of the spiral cable 1;

[0038] An anti-bending component 4, which is fixedly disposed between the terminal 2 and the spiral cable 1, and is elastic, and can support and protect the connection between the spiral cable 1 and the terminal 2;

[0039] A locking component 5, wherein the locking component 5 is plug-connected to the terminal 2, and the locking component 5 can lock and fix the terminal 2;

[0040] In order to solve the problem in the prior art that ordinary spiral cable assemblies are frequently bent or twisted at too small a radius when used in moving or rotating equipment, and especially the insulation layer at the connection is cracked, thereby exposing the internal conductor, the present application designs an anti-bending component 4, which can effectively further protect and support the connection between the spiral cable 1 and the terminal 2, avoiding the spiral cable 1 at the connection from bending at too small an angle, thereby reducing the phenomenon of outer layer breakage. Furthermore, in order to solve the problem that the terminal is easily pulled and the connection becomes loose during the movement and rotation of the spiral cable assembly, the present application designs a locking component 5, which can lock the terminal 2 through the locking component 5 to play a fixing role and avoid loosening;

[0041] A protective cover 3 is fixedly arranged between the spiral cable 1 and the terminal 2. The protective cover 3 can assist the connection between the spiral cable 1 and the terminal 2 and reduce cracking caused by pulling and bending.

[0042] The anti-bending component 4 includes a fixing ring 401, a rubber outer sleeve 402, a first fixing ring 403, a second fixing ring 404 and a connecting spring 405. The fixing ring 401 is fixedly arranged at the terminal 2. The side of the fixing ring 401 is fixedly connected with a rubber outer sleeve 402. The rubber outer sleeve 402 extends to the spiral cable 1 and wraps the connection between the spiral cable 1 and the terminal 2.

[0043] A first fixing ring 403 is fixedly connected to one end of the inner cavity of the rubber outer sleeve 402, and the first fixing ring 403 is in contact with and fixed to the terminal 2;

[0044] A second fixing ring 404 is fixedly connected to the other end of the inner cavity of the rubber outer sleeve 402, and a connecting spring 405 is fixedly arranged between the first fixing ring 403 and the second fixing ring 404;

[0045] The connecting springs 405 are provided in a plurality, and the plurality of connecting springs 405 are annularly fixed between the first fixing ring 403 and the second fixing ring 404. Through the technical solution, an anti-overbending component 4 is provided and fixed between the spiral cable 1 and the terminal 2, and the rubber outer sleeve 402 can further protect the connection between the spiral cable 1 and the terminal 2. At the same time, the connecting spring 405 can also support the rubber outer sleeve 402. When excessive bending occurs at the connection between the spiral cable 1 and the terminal 2, the elastic effect of the connecting spring 405 can have a certain effect of resisting the bending force. At the same time, after the bending force disappears, the anti-overbending component 4 can be quickly restored to its original position through the rebound of the connecting spring 405, thereby driving the spiral cable 1 to quickly restore to its original position, thereby avoiding the phenomenon of the insulation layer rupture caused by the spiral cable 1 being in an excessively bent state for a long time;

[0046] The locking component 5 includes a fixed socket 501, a limiting slider 502, a limiting block 503, a moving piece 504 and a limiting spring 505. The terminal 2 is plugged into the fixed socket 501, and a limiting protrusion 201 is fixedly provided on the side of the terminal 2.

[0047] The fixed socket 501 is provided with a slide groove inside, and a limit slider 502 is slidably provided in the slide groove of the fixed socket 501. A limit block 503 is fixedly connected to the side wall of the limit slider 502, and one end of the limit block 503 extends to the slot of the fixed socket 501;

[0048] The limit block 503 is provided with an inclined surface;

[0049] One end of the limiting spring 505 is fixedly connected to the side wall of the limiting slider 502, and the other end of the limiting spring 505 is fixedly connected to the inner cavity side wall of the fixed socket 501. A movable sheet 504 is slidably arranged at the side of the fixed socket 501, and the movable sheet 504 is fixedly connected to the limiting slider 502. Through the present technical solution, after the terminal 2 is inserted into the fixed socket 501, the limiting protrusion 201 contacts the limiting block 503 and pushes the limiting block 503 to retract. After the terminal 2 is fully inserted, the limiting block 503 is reset by the action of the limiting spring 505, thereby limiting and fixing the limiting protrusion 201, and then preventing the terminal 2 from loosening.
