[0002] As a signal or power connection between various electrical appliances, instruments and automatic devices, cables are generally integral cables. They are usually coiled up for storage and pulled out when needed. This makes the cables very easy to get tangled during use. Overly coiled and pulled cables can cause the outer insulation layer to crack and the inner core layer to deform under stress, thereby reducing the cable's conductivity and safety. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this utility model is to provide an anti-tangling connection device that prevents cables from getting tangled, greatly reduces the probability of knots during cable use, and effectively ensures the safety of cable use.

[0005] To achieve the above objectives, a first aspect of this utility model provides an anti-tangling connecting device for connecting a first segment and a second segment of a cable, the connecting device comprising:

[0008] Multiple conductive rings are arranged along the insertion / removal direction of the connector, and the energized part extends along the insertion / removal direction of the connector. When the conductive post is inserted into the receiving groove, the energized part abuts against the corresponding conductive ring, thereby achieving an electrical connection between the first connector and the second connector. The first and second segments of the cable rotate relative to each other, causing the first connector to rotate relative to the second connector. Since the cross-section of the conductive ring is circular, the energized part rotates along the circumferential direction of the conductive post, keeping the energized part in contact with the conductive ring.

[0011] According to another specific embodiment of the present invention, a portion of the energized part is bent to form a protruding section, the protruding section protruding toward the conductive post and used to abut against the corresponding conductive ring.

[0012] According to another specific embodiment of the present invention, the conductive post further includes a plurality of support posts corresponding to the conductive ring, one end of the support post is connected to the corresponding conductive ring, and the other end is welded to the core of the first segment of the cable; the support post is made of conductive material.

[0013] According to another specific embodiment of the present invention, the second connector further includes an energized cylindrical body, which is sleeved on the outside of the housing; the energized cylindrical body has an opening, and the inner wall of the energized cylindrical body is provided with conductive protrusions, and a contact ring is provided on the conductive post, the conductive post entering the energized cylindrical body through the opening and the conductive protrusion abutting against the contact ring.

[0024] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0025] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0026] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0029] In related technologies, cables are usually coiled for storage and pulled out directly when needed. This makes the cables very prone to tangling during use. For example, if a cable consists of a first segment and a second segment, excessive coiling and tightening during storage can cause the first segment to rotate relative to the second segment. This can easily cause the outer insulation layer to crack at the connection between the first and second segments, and the inner core layer to deform under stress, thereby reducing the cable's conductivity and safety.

[0030] This embodiment provides an anti-tangling connection device, such as... Figures 1 to 3As shown, a connecting device for connecting a first segment 310 and a second segment 320 of a cable 300 includes a first connector 100 and a second connector 200. The first connector 100 is used for electrical connection with the first segment 310 of the cable 300. The first connector 100 includes a conductive post 110, which has at least two conductive rings 120. The conductive rings 120 are arranged along the insertion and removal direction of the connecting device. The second connector 200 is used for electrical connection with the second segment 320 of the cable 300. The second connector 200 includes a housing 210 and at least two energized parts 220. The housing 210 has a receiving groove 211. The energized parts 220 are disposed in the housing 210 and extend along the insertion and removal direction of the connecting device. The energized parts 220 and the conductive rings 120 correspond to each other. The conductive post 110 is inserted into the receiving groove 211, and the energized part 220 abuts against the corresponding conductive ring 120, so that the first connector 100 and the second connector 200 are electrically connected.

[0031] Multiple conductive rings 120 are arranged along the insertion and removal direction of the connector, and the energized part 220 extends along the insertion and removal direction of the connector. When the conductive post 110 is inserted into the receiving groove 211, the energized part 220 abuts against the corresponding conductive ring 120, thereby realizing the electrical connection between the first connector 100 and the second connector 200. The first segment 310 and the second segment 320 of the cable 300 rotate relative to each other, causing the first connector 100 to rotate relative to the second connector 200. Since the cross-section of the conductive ring 120 is circular, the energized part 220 rotates along the circumferential direction of the conductive post 110, so that the energized part 220 and the conductive ring 120 remain in contact, thereby preventing the cable 300 from tangling, greatly reducing the probability of knotting during the use of the cable 300, and effectively ensuring the safety of the cable 300 during use.

[0032] The cable 300 includes a first segment 310 and a second segment 320. When the cable 300 is wound up, the first segment 310 rotates relative to the second segment 320. The energized part 220 rotates in the circumferential direction of the corresponding conductive ring 120, and the energized part 220 and the conductive ring 120 remain in contact. By ensuring that the first segment 310 and the second segment 320 of the cable 300 rotate relative to each other, the first segment 310 and the second segment 320 of the cable 300 maintain electrical contact through the connecting device, thereby preventing the cable 300 from tangling. The energized part 220 abuts against the corresponding conductive ring 120, meaning that the energized part 220 abuts against the outer wall of the conductive ring 120.

[0033] In some embodiments, two conductive rings 120 are provided, and two corresponding energized portions 220 are provided; the two energized portions 220 are opposite to each other, and a clamping position 221 for the conductive post 110 is formed between the two energized portions 220. The two opposite energized portions 220 ensure that the relative position between the energized portion 220 and the conductive ring 120 is maintained during the process of the first connector 100 relative to the second connector 200, preventing the energized portion 220 and the conductive ring 120 from disengaging and affecting the conductivity.

[0034] In some embodiments, the end of the conductive post 110 has an inclined guide surface 111, which makes it easier to insert the conductive head into the clamping position 221 for easy installation.

[0035] In some embodiments, the energized part 220 is a spring sheet; the elasticity of the spring sheet makes it easier for the energized part 220 to deform and return to its original position under force, thereby keeping the energized part 220 in contact with the side wall of the conductive ring 120 to ensure conductivity; the end of the energized part 220 is welded to the second segment 320 of the cable 300, so that the energized part 220 can be firmly fixed to the cable 300, reducing the risk of the energized part 220 and the second segment 320 of the cable detaching due to vibration or other reasons; in addition, the resistance of the welded connection point is usually low, which can reduce signal or current loss and maintain good conductivity.

[0036] In some embodiments, the energized part 220 includes a first energized part 222 and a second energized part 223. The end of the first energized part 222 passes through the bottom of the housing 210 and is soldered to the second live wire of the second segment 320 of the cable 300. The end of the second energized part 223 passes through the bottom of the housing 210 and is soldered to the second neutral wire of the cable 300. The first conductive ring 121 is located on the side of the second conductive ring 122 away from the second segment 320 of the cable 300. The length of the first energized part 222 is greater than the length of the second energized part 223, such that the first energized part 222 abuts against the first conductive ring 121 and the second energized part 223 abuts against the second conductive ring 122.

[0037] In some embodiments, a portion of the energized part 220 is bent to form a protruding section 224. The protruding section 224 protrudes toward the conductive post 110 and is used to abut against the corresponding conductive ring 120, which is more conducive to the electrical connection between the energized part 220 and the corresponding conductive ring 120. In addition, by having the bent protruding section 224 abut against the conductive ring 120, the distance between other parts of the energized part 220 and the conductive post 110 can be increased as much as possible, avoiding problems such as short circuits caused by other parts of the energized part 220 contacting the conductive post 110.

[0038] In some embodiments, the conductive post 110 further includes a plurality of support posts corresponding to the conductive ring 120. The support posts are made of conductive material, with one end connected to the corresponding conductive ring 120 and the other end welded to the core of the first segment 310 of the cable 300. This allows the support post to be firmly fixed to the cable 300, reducing the risk of the support post and the first segment 310 of the cable 300 becoming detached due to vibration or other reasons. Furthermore, the resistance at the welded connection point is typically low, reducing signal or current loss and maintaining good conductivity. The support post and conductive ring 120 can be made of metal.

[0039] In some embodiments, the support column includes a first support column 131 and a second support column 132. One end of the first support column 131 is connected to a first conductive ring 121, and the other end is soldered to the first live wire of the first segment 310 of the cable 300. One end of the second support column 132 is connected to a second conductive ring 122, and the other end is soldered to the first neutral wire of the first segment 310 of the cable 300. A first energized part 222 abuts against the first conductive ring 121, causing the first live wire of the first segment 310 of the cable 300 and the second live wire of the second segment 320 to be conductive. A second energized part 223 abuts against the second conductive ring 122, causing the first neutral wire of the first segment 310 of the cable 300 and the second neutral wire of the second segment 320 to be conductive. Generally, the first support column 131 is a rod, and the second support column 132 is a cylinder, with the second support column 132 sleeved on the outside of the cable 300.

[0040] In some embodiments, the conductive post 110 further includes an insulating cylinder 140, which is located between the first support post 131 and the second support post 132 to prevent the first support post 131 and the second support post 132 from coming into contact and causing a short circuit.

[0041] In some embodiments, the second connector 200 further includes a power-conducting cylindrical body 230, which is sleeved on the outside of the housing 210. The power-conducting cylindrical body 230 has an opening, and the inner wall of the power-conducting cylindrical body 230 is provided with conductive protrusions 231. A contact ring 160 is provided on the conductive post 110. The conductive post 110 enters the power-conducting cylindrical body 230 through the opening, and the conductive protrusions 231 abut against the contact ring 160. Since the cross-section of the contact ring 160 is circular, the conductive protrusions 231 and the contact ring 160 remain in contact during the rotation of the power-conducting cylindrical body 230 relative to the conductive post 110. Under the premise that the first connector 100 and the second connector 200 rotate relative to each other, the electrical contact between the power-conducting cylindrical body 230 and the contact ring 160 can be maintained, so that the first segment 310 and the second segment 320 of the cable 300 can rotate relative to each other, thereby preventing the cable 300 from getting tangled during use. Generally, the housing 210 is made of insulating material, which can isolate the energized cylinder 230 and the energized part 220. The energized cylinder 230 is welded to the second grounding wire of the second segment 320 of the cable 300, and the grounding ring 160 is welded to the first grounding wire of the first segment 310 of the cable 300.

[0042] In some embodiments, the connecting device further includes an insulating member 170, which is a cylindrical body. The insulating member 170 is sleeved on the outside of the second support column 132, and the contact ring 160 is located outside the insulating member 170 to isolate the contact ring 160 from the second support column 132.

[0043] In some embodiments, the first connector includes a base 150, and a conductive post 110 is fixed to the base 150; the second connector 200 includes a protective shell 240, which is sleeved on the outside of the energized cylinder 230. The protective shell 240 and the base 150 are spirally connected. The protective shell 240 can play a protective role, preventing external dust, moisture, etc. from entering the interior of the connector, and playing a further waterproof role; the conductive protrusion 231 is annular and is located at the opening of the energized cylinder 230.

[0044] A second aspect of this utility model provides an underwater robot, comprising a robot body, a first segment 310 of a cable 300, a second segment 320 of the cable 300, and an anti-tangling connection device provided in any embodiment of the first aspect; a first connector 100 connects to the first segment 310 of the cable 300, and a second connector 200 connects to the second segment 320 of the cable 300; one of the first segment 310 and the second segment 320 of the cable 300 is connected to the robot body, and the other is used to connect to a power source.

The specific implementation method can be referred to the above embodiments, and will not be repeated in this application.

[0046] The cable 300 may also include a third segment and a fourth segment. The connecting device can be connected between the first segment 310 and the second segment 320, between the second segment 320 and the third segment, or between the third segment and the fourth segment of the cable 300. Multiple connecting devices can be provided, and multiple connecting devices can be provided at different positions on the cable 300 to further reduce the probability of the cable 300 becoming tangled, twisted, or knotted during use.
