[0002] A cable is an assembly in which one or more insulated electric wires are combined together and may be wrapped by one or more mutually insulated sheaths. They are used in power, communication, and control systems to transmit electrical energy or signals. A cable usually consists of a conductor (such as copper or aluminum), an insulating material (such as polyvinyl chloride PVC or cross-linked polyethylene XLPE), a filler, a shielding layer, and an outer sheath. These components together ensure the electrical performance, mechanical strength, and environmental adaptability of the cable.

[0003] After retrieval, there is a retractable cable with the existing application number CN202322610739.1, which includes a housing. A partition is fixedly connected to the rear part inside the housing. A round box penetrates and is rotatably connected to the middle part at the rear side of the partition. A scroll spring penetrates and is arranged inside the rear side of the round box, and the outer end of the scroll spring is fixedly connected to the inner wall of the round box.

Detailed implementation manners

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Embodiment:

[0031] Please refer to Figures 1 to 4 , the present invention provides a technical solution:

[0032] A cable connector structure and a tensile-resistant cable, comprising:

[0033] A winding box 1, the outer side walls at both ends of the winding box 1 are provided with cranks 2, the cranks 2 are fixedly connected to the first rotating shaft 5, the top of the winding box 1 is provided with a handle 402, the inner sides of both sides of the winding box 1 are respectively provided with a first winding chamber 101 and a second winding chamber 102, the upper end inside the first winding chamber 101 is provided with a first rotating shaft 5, a second rotating shaft 6 and a third rotating shaft 7, a connecting rod is provided between the first rotating shaft 5 and the second rotating shaft 6, and a winding assembly 3 for driving the winding roller 8 to rotate to unwind or wind the cable is arranged on the three rotating shafts.

[0034] Specifically, as Figure 3 shown, the winding assembly 3 includes a first gear 301, the first gear 301 is sleeved on the first rotating shaft 5, the first gear 301 meshes with a second gear 302 on the third rotating shaft 7, and the diameter of the first gear 301 is smaller than that of the second gear 302.

[0035] Specifically, the second gear 302 is sleeved on the third rotating shaft 7. The rear end of the third rotating shaft 7 is provided with a third gear 303. The third gear 303 rotates as the second gear 302 rotates. The diameter of the third gear 303 is smaller than that of the second gear 302.

[0036] Specifically, the third gear 303 meshes with a winding gear 304 located at the lower end of the first winding chamber 101. The winding gear 304 is sleeved on a winding roller 8. The diameter of the winding gear 304 is much larger than those of the first gear 301, the second gear 302, and the third gear 303.

[0037] Specifically, the front end of the third rotating shaft 7 is provided with a ratchet wheel 4. Above the ratchet wheel 4, there is a latch 401 for latching the ratchet wheel 4. The latch 401 is sleeved on the second rotating shaft 6. The end of the latch 401 has a handle 402 extending out of the housing of the winding box 1 to the outside.

[0038] Specifically, the first winding chamber 101 and the second winding chamber 102 have the same structure and are mirror - symmetrically arranged with the partition in the center of the winding box 1 as the axis of symmetry. Through - holes are opened at the bottom of the partition between the centers of the two winding chambers for passing through the cable 15.

[0039] In this embodiment, the cable 15 is wound around the winding roller 8. When the cable needs to be stretched in a specific direction, only the crank 2 in the corresponding direction needs to be rotated. The crank 2 will drive the first rotating shaft 5 to rotate. The first gear 301 on the first rotating shaft 5 meshes with the second gear 302, and the diameter of the first gear 301 is smaller than that of the second gear 302. Therefore, the number of teeth of the second gear 302 is more than that of the first gear 301, and the rotation angle is small. Since the gear 302 is sleeved on the third rotating shaft 7, the third rotating shaft 7 will drive the third gear 303 to rotate. Since the third gear 303 meshes with the winding gear 304, and the diameter of the third gear 303 is much smaller than that of the winding gear 304, the number of teeth of the third gear 303 is less than that of the winding gear 304, and the rotation angle is large, so as to achieve a transmission structure. Through the cooperation of multiple groups of gears and the crank 2, a labor - saving structure can be formed while stretching the cable.

[0040] When the cable 15 needs to be retracted, only the handle 402 of the ratchet wheel 4 needs to be pressed downward so that the latch 401 no longer latches the ratchet wheel 4, enabling the crank 2 to rotate in the reverse direction. Through the reverse transmission of multiple groups of gears, the cable can be retracted while saving labor.

[0041] The cable 15 will drive the winding roller 8 to rotate. Since the winding gear 304 on the winding roller 8 meshes with the third gear 303, and the diameter of the winding roller 8 is much larger than

[0042] A cable joint structure, comprising:

[0043] Cable joint 9, the cable joint 9 is connected to the cable 15 extending from the lower end of the winding box 1. The cable joint 9 is arranged on the front and back sides of the winding box 1 to facilitate the bidirectional stretching of the cable 15 during use. The rear end of the cable joint 9 has a fixing clip 10, and the fixing clip 10 fixes and clamps the cable 15 through a screw 1001. The front end of the cable joint 9 has an interface 14, and the middle of the cable joint 9 has an insulating layer 12. The outside of the insulating layer 12 has a fixing component 11.

[0044] Specifically, as Figure 5 shown, the fixing component 11 includes a clamping block 1101, the clamping block 1101 is rotatably connected to a rotating shaft 1104, the part of the front end of the clamping block 1101 that abuts against the cable 15 is in a barbed serrated shape, and the upper end surface of the front end of the clamping block 1101 has a telescopic rod 1103, and a return spring 1102 is sleeved outside the telescopic rod 1103.

[0045] Specifically, the fixing clip 10 includes a first fixing clip 1002 and a second fixing clip 1003, and the interfaces of the first fixing clip 1002 and the second fixing clip 1003 are in a groove clamping structure with each other.

[0046] In this embodiment, the cable 15 is inserted into the cable joint 9 through one side of the fixing clip 10 of the cable joint 9, then the clamping structure of the first fixing clip 1002 and the second fixing clip 1003 is pressed, and then the screw 1001 is used to screw into the threaded holes on both sides of the fixing clip 10 to clamp the cable 15.

[0047] When the cable 15 is inserted, the barbs at the front end of the clamping block 1101 of the fixing component 11 will hinder the insertion of the cable 15. At this time, press the rear end of the clamping block 11 so that the rear end rotates into the avoidance groove of the insulating layer 12 through the rotating shaft 1104, and the barbed part at the front end moves away from the cable 15 on both sides, so that the cable 15 can be inserted into the cable joint 9 without damaging the fixing component 11. Since there is a telescopic rod 1103 with a return spring 1102 sleeved on the upper end surface of the front end of the clamping block 1101, in the normal state, the return spring 1102 will drive the telescopic rod 1103 to continuously provide a force to clamp the cable 15 to the bottom clamping block 1101. Then, it can be connected to other cable interfaces through the front interface 14.

[0048] During use, the barbed part will hook the rubber skin of the cable 15 to cooperate with the fixing clip 10 to complete the fixation of the cable. At the same time, the front interface 14 of the cable joint 9 has a waterproof layer.

[0049] When the cable needs to be taken out, only need to unscrew the screw 1001, disassemble the fixing clip 10, press the rear end of the clamping block 1101, and lift the barbed part at the front end, then the cable 15 can be pulled out.

[0050] For the present utility model, the parts not described herein may be the same as the prior art, or be well-known technologies, or can be implemented by adopting the prior art, and will not be elaborated herein.

[0051] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
