[0028] The technical solution of the present application will be described below in conjunction with the drawings in the implementation modes of the present application. Obviously, the described implementation modes are only part of the implementation modes of the present application, rather than all the implementation modes.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0031] Currently, electrical transmission is achieved by electrically connecting cables to each other, but when the cables are connected to each other, there is often a problem of difficulty in docking. For example, the connectors used for docking in each cable do not match each other, and additional accessories need to be added during docking, resulting in reduced docking efficiency. In addition, most cables are docked by plugging and unplugging, so the cable connectors and wiring harnesses are prone to loosening during docking, resulting in reduced cable stability, which in turn causes poor contact between cables, resulting in failure of electrical transmission and endangering the personal safety of operators.

[0032] In view of this, it is necessary to provide a cable that can improve docking efficiency and stability and a cable set having the cable. The cable includes a male connector, a female connector, a first ring and a second ring. The female connector and the male connector are pluggable and adaptable. One end of the wiring harness is connected to the male connector, and the other end is connected to the female connector. The first ring is located in the male connector and the female connector and is clamped around the wiring harness. The second ring is located in the male connector and the female connector and is clamped around the first ring.

[0033] In the above-mentioned cable, a male connector is provided at one end of the wiring harness, and a female connector is provided at the other end, and the female connector and the male connector are pluggable and adaptable. When docking, the male connector of one cable can be directly plugged into the female connector of another cable, and the female connector of one cable can also be directly plugged into the male connector of another cable, eliminating additional accessories and improving docking efficiency. In addition, the cable also has a first ring and a second ring in the female connector and the male connector. The wiring harness is tightened by the first ring, and then the first ring is clamped by the second ring and squeezed inwardly, thereby further tightening the wiring harness, making the connection between the wiring harness and the female connector and the male connector more stable. When plugging and unplugging the female connector and the male connector, the risk of the wiring harness falling off the female connector and the male connector is reduced, thereby reducing the probability of causing poor contact between cables, resulting in failure of electrical transmission, and endangering the personal safety of operators.

[0034] The following is combined with Figures 1 to 13 , some embodiments of the present application are described in detail. In the absence of conflict, the following embodiments and features of the embodiments can be combined with each other.

[0035] like Figures 1 to 3 As shown, the present application provides a cable 100. The cable 100 is used for electrical transmission, such as transmitting electrical energy or transmitting signals. The cable 100 includes a wiring harness 10, a male connector 20, and a female connector 30. One end of the wiring harness 10 is connected to the male connector 20, and the other end of the wiring harness 10 is connected to the female connector 30. The female connector 30 and the male connector 20 are pluggable and adaptable, that is, the female connector 30 and the male connector 20 can be directly plugged into each other without any additional accessories.

[0036] When using the cable 100, in the case that the length of a single cable 100 is insufficient, the male connector 20 of one cable 100 can be directly connected to the female connector 30 of another cable 100, or the female connector 30 of one cable 100 can be directly connected to the male connector 20 of another cable 100, so that multiple cables 100 are connected end to end in sequence to extend the total length of electrical transmission. Moreover, since the female connector 30 and the male connector 20 can be directly plugged into each other without any additional accessories, the docking of the cables 100 is more convenient and quick, thereby improving the docking efficiency of the cables 100.

[0037] For example, when the length of the first cable 100 is not enough, a second cable 100 can be added. If the male connector 20 of the first cable 100 is occupied, the female connector 30 of the first cable 100 can be directly connected to the male connector 20 of the second cable 100, and then the female connector 30 of the second cable 100 can be connected to the required equipment, thereby compensating for the insufficient length of a single cable 100 and achieving the purpose of extending the total length of electrical transmission.

[0038] For another example, multiple cables 100 can be connected in sequence to extend the total length of electrical transmission indefinitely. Specifically, if the male connector 20 of the first cable 100 is occupied, the female connector 30 of the first cable 100 can be directly connected to the male connector 20 of the second cable 100, and then the female connector 30 of the second cable 100 can be directly connected to the male connector 20 of the third cable 100, and then the female connector 30 of the third cable 100 can be directly connected to the male connector 20 of the fourth cable 100, and so on, until the female connector 30 of the last cable 100 is connected to the required device.

[0039] like Figure 1 , Figure 4 and Figure 5 As shown, in some embodiments, the cable 100 further includes a first ring 40 and a second ring 50. The first ring 40 and the second ring 50 are both disposed in the male connector 20 and the female connector 30, that is, the male connector 20 is provided with the first ring 40 and the second ring 50, and the female connector 30 is also provided with the first ring 40 and the second ring 50. The first ring 40 hoops the wiring harness 10 and tightens the wiring harness 10, and the second ring 50 hoops the first ring 40 and squeezes the first ring 40 inward, thereby further tightening the wiring harness 10, so that the friction between the wiring harness 10 and the first ring 40 is large enough, so that the position of the wiring harness 10 relative to the first ring 40 is fixed, and because the positions of the first ring 40 and the second ring 50 relative to the male connector 20 and the female connector 30 are fixed, the position of the wiring harness 10 relative to the male connector 20 and the female connector 30 is also fixed, thereby ensuring the connection stability between the wiring harness 10 and the male connector 20 and the female connector 30, and reducing the risk of the wiring harness 10 falling off the male connector 20 and the female connector 30 when plugging and unplugging the male connector 20 and the female connector 30, thereby reducing the probability of causing poor contact between cables 100 and cables 100, resulting in failure of electrical transmission and endangering the personal safety of operators.

[0040] In some embodiments, the first ring member 40 includes a first ring body 41 and a second ring body 42 connected to each other, the first ring body 41 hoops the wire harness 10 and is used to tighten the wire harness 10, and the second ring body 42 protrudes radially outward from the first ring body 41. The second ring member 50 includes a third ring body 51 connected to each other and a plurality of claws 52, the plurality of claws 52 are distributed at intervals along the circumference of the third ring body 51, the third ring body 51 hoops the first ring body 41, and the claws 52 are used to press the first ring body 41 toward the wire harness 10, so that the first ring body 41 further tightens the wire harness 10.

[0041] When assembling the first ring member 40 and the second ring member 50, the third ring body 51 is radially encircled by the first ring body 41 until the third ring body 51 abuts against the second ring body 42. The second ring body 42 serves to stop the third ring body 51 to limit the position of the third ring body 51, so as to determine whether the first ring member 40 and the second ring member 50 are assembled in place.

[0042] After the first ring member 40 and the second ring member 50 are assembled in place, the first ring body 41 extends between the plurality of claws 52 and the wire harness 10. The minimum spacing between each claw 52 and the wire harness 10 is set to be smaller than the radial thickness of the first ring body 41, so when the first ring body 41 extends between the plurality of claws 52 and the wire harness 10, the plurality of claws 52 are elastically deformed, and at the same time, the plurality of claws 52 squeeze the first ring body 41 through elastic restoring force to increase the interaction force between the first ring body 41 and the wire harness 10, thereby increasing the friction between the first ring body 41 and the wire harness 10, so that the position of the wire harness 10 relative to the first ring body 41 is more stable and not easy to shift.

[0043] As an illustrative example, the first ring 40 is made of an elastic material, such as rubber, so that the first ring 40 can pass through the elastic tight harness 10. The rigidity of the second ring 50 is greater than that of the first ring 40, such as metal, so that the second ring 50 can squeeze the first ring 40 with a sufficiently large force.

[0044] In some embodiments, one end of the male connector 20 and the female connector 30 are both provided with an opening 230. Specifically, the opening 230 is a male end opening 21 in the male connector 20, and the opening 230 is a female end opening 31 in the female connector 30. The male end opening 21 allows the wire harness 10, the first ring 40, and the second ring 50 to enter the male connector 20 during assembly. The female end opening 31 allows the wire harness 10, the first ring 40, and the second ring 50 to enter the female connector 30 during assembly. The cable 100 further includes a third ring 60. The male connector 20 and the female connector 30 are both provided with the third ring 60, and the male end opening 21 and the female end opening 31 are blocked by the third ring 60. The third ring 60 is provided with a through hole 61, and the through hole 61 allows the wire harness 10 to pass through.

[0045] Optionally, after the male connector 20 and the female connector 30 are assembled, the end of the first ring body 41 away from the second ring body 42 blocks the gap between the hole wall of the through hole 61 and the wiring harness 10 to ensure the sealing of the male connector 20 and the female connector 30.

[0046] Optionally, the third ring 60 is connected to the male connector 20 and the female connector 30 through threads to ensure connection stability and sealing.

[0047] In some embodiments, the claw 52 includes an extension portion 521 and an extrusion portion 522, one end of the extension portion 521 is connected to the third ring body 51, the other end of the extension portion 521 extends along the axial direction of the third ring body 51 and is connected to the extrusion portion 522, and the extrusion portion 522 protrudes radially inwardly of the third ring body 51. After the first ring member 40 and the second ring member 50 are assembled in place, the first ring body 41 extends between the extrusion portion 522 and the wire harness 10, and the distance between the extrusion portion 522 and the wire harness 10 is set to be smaller than the radial thickness of the first ring body 41, so that the extension portion 521 is elastically deformed, so that the extension portion 521 squeezes the first ring body 41 through the extrusion portion 522 under the action of elastic recovery.

[0048] Optionally, each claw 52 may have a plurality of pressing portions 522 , which are arranged at intervals along the extension portion 521 to increase the pressing area of ​​the claw 52 on the first ring body 41 , thereby further improving the connection stability between the wire harness 10 and the first ring body 41 .

[0049] Also optionally, the extrusion portion 522 may be omitted, and the claw 52 only has an extension portion 521. After the first ring member 40 and the second ring member 50 are assembled in place, the first ring body 41 extends between the extension portion 521 and the wiring harness 10, and the distance between the extension portion 521 and the wiring harness 10 is set to be smaller than the radial thickness of the first ring body 41, so that the extension portion 521 produces elastic deformation, thereby causing the extension portion 521 to squeeze the first ring body 41 through the elastic restoring force.

[0050] like Figure 1 , Figure 2 and Figures 6 to 9 As shown, in some embodiments, the male connector 20 includes a plug-in portion 22 and a sealing ring 23, and the sealing ring 23 is arranged around the outer surface of the plug-in portion 22. The female connector 30 is provided with a socket 32. When the male connector 20 and the female connector 30 are plugged in, the plug-in portion 22 is inserted into the socket 32, and the sealing ring 23 blocks the gap between the outer surface of the plug-in portion 22 and the inner wall of the socket 32 ​​to ensure the sealing between the male connector 20 and the female connector 30.

[0051] Optionally, there are multiple sealing rings 23, such as two, three or five, and the multiple sealing rings 23 are arranged at intervals to improve the sealing performance.

[0052] In some embodiments, the plug-in portion 22 is provided with a terminal port 221, the wiring harness 10 includes a connecting wire 11, a male terminal 12 and a female terminal 13, the male terminal 12 is provided at one end of the connecting wire 11 and is provided in the terminal port 221, and the female terminal 13 is provided at the other end of the connecting wire 11 and is provided in the socket 32. When the male connector 20 is plugged into the female connector 30, the female terminal 13 is inserted into the terminal port 221 and plugged into the male terminal 12 to electrically connect the two plugged connecting wires 11.

[0053] Optionally, the male terminal 12 is columnar and the female terminal 13 is sleeve-shaped. When the male connector 20 and the female connector 30 are plugged in, the female terminal 13 is inserted into the gap between the male terminal 12 and the inner wall of the terminal opening 221 , and at the same time, the male terminal 12 is inserted into the female terminal 13 .

[0054] In some embodiments, the wiring harness 10 includes three connecting wires 11, three female terminals 13 are provided in the socket 32, and the plug-in portion 22 is provided with three terminal ports 221, each terminal port 221 is provided with a male terminal 12, and the three terminal ports 221 and the three female terminals 13 are distributed as the three vertices of the same triangle. When the male connector 20 and the female connector 30 are plugged in, it can play an anti-mock role, facilitate the identification of the plug-in direction, and improve the plug-in efficiency.

[0055] It should be noted that, when the wiring harness 10 includes multiple connecting wires 11, the multiple connecting wires 11 are wrapped and gathered by the insulating outer skin 14 to form the entire wiring harness 10, but inside the male connector 20 and the female connector 30, the multiple connecting wires 11 need to be separated to achieve the spaced distribution of the male terminal 12 and the female terminal 13. At this time, the first ring member 40 clamps the wiring harness 10, which can not only tighten the wiring harness 10, but also gather the multiple connecting wires 11, thereby reducing the shaking of each connecting wire 11 inside the male connector 20 and the female connector 30 due to excessive separation, thereby improving the stability of the male terminal 12 and the female terminal 13.

[0056] In some embodiments, the male terminal 12 is provided with a male notch 121, and the female terminal 13 is provided with a female notch 122. A wire 111 is provided inside the connecting wire 11. The connecting wire 11 and the male terminal 12 are connected in the following manner: the wire 111 extends into the male notch 121, and the male terminal 12 fixes the wire 111 at the male notch 121 by crimping operation to electrically connect the wire 111 and the male terminal 12. The connecting wire 11 and the female terminal 13 are connected in the following manner: the wire 111 extends into the female notch 122, and the female terminal 13 fixes the wire 111 at the female notch 122 by crimping operation to electrically connect the wire 111 and the female terminal 13.

[0057] Optionally, both the male terminal 12 and the female terminal 13 have a crimping portion 123, which is sheet-shaped and bent into a U-shape before the crimping operation, and the male notch 121 and the female notch 122 are formed in the crimping portion 123. The crimping portion 123 will tighten the wire 111 after the crimping operation, thereby fixing the wire 111. The crimping portion 123 is U-shaped before the crimping operation, so that the wires 111 of various types of connecting wires 11 can be inserted into the male notch 121 and the female notch 122 for crimping operation, so that the male terminal 12 and the female terminal 13 can be adapted to connect various types of connecting wires 11, so as to improve the adaptability of the male terminal 12 and the female terminal 13.

[0058] like Figure 3 , Figure 6 , Fig.10 and Fig.11 As shown, in some embodiments, the male connector 20 is provided with a buckle 24, and the female connector 30 is provided with a slot 33. The buckle 24 includes a plate 241 and a protrusion 242, one end of the plate 241 is connected to the male connector 20, and the protrusion 242 is provided at the end of the plate 241 away from the male connector 20, the plate 241 is elastic, and the protrusion 242 has an inclined surface 2421 and a first limiting surface 2422 arranged backward. The slot wall of the slot 33 has a second limiting surface 331. During the plugging process of the male connector 20 and the female connector 30, the inclined surface 2421 is used to guide the protrusion 242 to slide into the slot 33, and the plate body 241 is deformed. When the protrusion 242 slides over the second limiting surface 331, the plate body 241 restores its deformation, so that the first limiting surface 2422 and the second limiting surface 352 are arranged opposite to each other, and the second limiting surface 352 is used to stop the first limiting surface 2422 to prevent the protrusion 242 from disengaging from the slot 33, thereby locking the connection between the male connector 20 and the female connector 30, so that the male connector 20 and the female connector 30 are tightly connected, reducing the accidental loosening of the male connector 20 and the female connector 30, and improving the connection stability.

[0059] Optionally, the slot wall of the card slot 33 further has a first covering surface 332 and a second covering surface 333, and the first covering surface 332 and the second covering surface 333 are respectively arranged on opposite sides of the second limiting surface 331. After the male connector 20 and the female connector 30 are plugged in, the first covering surface 332 covers the plate 241 of the buckle 24, and the second covering surface 333 covers the protrusion 242 of the buckle 24, thereby covering the buckle 24. The female connector 30 is provided with an opening 34 connected to the card slot 33 on the side of the second limiting surface 331 facing the second covering surface 333, and the opening 34 is used for a specific tool (such as a screwdriver, etc.) to extend into the card slot 33, and the protrusion 242 is pressed by the specific tool to displace the first limiting surface 2422 and the second limiting surface 331, thereby allowing the protrusion 242 to slide out of the card slot 33, thereby disassembling the connection between the male connector 20 and the female connector 30.

[0060] When disassembling the male connector 20 and the female connector 30, since the buckle 24 is covered by the first covering surface 332 and the second covering surface 333 after being inserted into the slot 33, and the opening 34 can be set to a size that is difficult to insert fingers, it is difficult for people to directly press the buckle 24 with bare hands, and the buckle 24 can only be detached from the slot 33 with the use of specific tools, thereby reducing the possibility of people disassembling the male connector 20 and the female connector 30 with bare hands, thereby improving safety.

[0061] In some embodiments, the buckle 24 is made of polybutylene terephthalate (PBT) plus glass fiber (GF), which improves the dimensional stability of the buckle 24 under higher temperature conditions and makes the buckle 24 have sufficient strength and plasticity, thereby extending the service life of the buckle 24.

[0062] In some embodiments, a buckle 24 is provided on each of the opposite sides of the male connector 20, and correspondingly, a slot 33 is provided on each of the opposite sides of the female connector 30. After the male connector 20 and the female connector 30 are plugged in, the buckle 24 and the slot 33 on the same side cooperate to improve the connection stability between the male connector 20 and the female connector 30.

[0063] It is understandable that the buckle 24 may also be provided on the female connector 30 , and correspondingly, the slot 33 may also be provided on the male connector 20 .
