[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.

[0005] The first aspect of this utility model provides an anti-entanglement connection mechanism assembly, comprising:
[0006] A first connector is used for electrical connection with a first segment of the cable; the first connector includes a conductive cylinder having an inner wall and an outer wall.
[0007] The second connector is used for electrical connection with the second segment of the cable; the second connector includes a housing and a first energized part and a second energized part, the housing having a receiving groove; the first energized part and the second energized part are both disposed in the housing and extend along the insertion and removal direction of the connection mechanism; a clamping position is formed between the first energized part and the second energized part; the conductive cylinder is inserted into the receiving groove and the conductive cylinder is inserted into the clamping position, and the first energized part abuts against the inner wall of the conductive cylinder, and the second energized part abuts against the outer wall of the conductive cylinder, so that the first connector and the second connector are electrically connected.
[0008] According to another specific embodiment of the present invention, the first connector further includes a conductive post, which is disposed inside the conductive cylinder, and an insulating gap is formed between the conductive post and the inner wall of the conductive cylinder; the second connector further includes a power-conducting post; when the conductive cylinder is inserted into the receiving groove, the conductive post abuts against the power-conducting post.
[0009] According to another specific embodiment of the present invention, the conductive post is located on the central axis of the conductive cylinder.
[0010] According to another specific embodiment of the present invention, the inner wall and outer wall of the conductive cylinder are both made of conductive material, and an insulating material is provided between the inner wall and the outer wall of the conductive cylinder.
[0011] According to another specific embodiment of the present invention, the first energized part and the second energized part are springs; the ends of the first energized part and the second energized part are welded to the second segment of the cable.
[0012] According to another specific embodiment of the present invention, a portion of the first energized part and / or the second energized part is bent to form a protruding section, the protruding section protruding toward the conductive cylinder and used to abut against the corresponding inner wall or the outer wall.
[0013] According to another specific embodiment of the present invention, the first connector includes a base, and the housing is fixed to the base; the second connector includes a protective shell, which is sleeved on the outside of the conductive cylinder, and the protective shell and the base are spirally connected.

[0015] The present invention has at least the following beneficial effects:
[0016] The conductive cylinder is inserted into the receiving groove of the housing. The first and second energized parts extend along the insertion and removal direction of the connecting mechanism. When the conductive post is inserted into the receiving groove, the first energized part abuts against the inner wall of the conductive cylinder, and the second energized part abuts against the outer wall of the conductive cylinder, thereby realizing the 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 cylinder is circular, the first and second energized parts rotate along the circumferential direction of the conductive post, keeping the first energized part in contact with the inner wall of the conductive cylinder and the second energized part in contact with the outer wall of the conductive cylinder.

[0031] Reference Figures 1 to 5 The following are several embodiments of the anti-entanglement connection mechanism and underwater robot of this utility model.
[0032] like Figures 1 to 4 As shown, this embodiment provides an anti-tangling connection mechanism for connecting a first segment 310 and a second segment 320 of a cable 300. The connection mechanism 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 cylinder 110, which has an inner wall 111 and an outer wall 112. 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, a first energized part 211, and a second energized part 212. 12. The housing 210 is provided with a receiving groove 213; the first energized part 211 and the second energized part 212 are both provided in the housing 210 and extend along the insertion and removal direction of the connecting mechanism; a clamping position 214 is formed between the first energized part 211 and the second energized part 212; the conductive tube 110 is inserted into the receiving groove 213 and the conductive tube 110 is inserted into the clamping position 214, and the first energized part 211 abuts against the inner wall 111 of the conductive tube 110, and the second energized part 212 abuts against the outer wall 112 of the conductive tube 110, so that the first connector 100 and the second connector 200 are electrically connected.
[0033] The conductive cylinder 110 is inserted into the receiving groove 213 of the housing 210. The first energized part 211 and the second energized part 212 extend along the insertion and removal direction of the connecting mechanism. When the conductive cylinder 110 is inserted into the receiving groove 213, the first energized part 211 abuts against the inner wall 111 of the conductive cylinder 110, and the second energized part 212 abuts against the outer wall 112 of the conductive cylinder 110, 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. The first connector 100 rotates relative to the second connector 200. Since the cross-section of the conductive cylinder 110 is circular, the first energized part 211 and the second energized part 212 rotate along the circumferential direction of the conductive post 120, so that the first energized part 211 and the inner wall 111 of the conductive cylinder 110 remain in contact, and the second energized part 212 and the outer wall 112 of the conductive cylinder 110 remain in contact, thereby preventing the cable 300 from getting tangled, greatly reducing the probability of knotting during the use of the cable 300, and effectively ensuring the safety of the cable 300 during use.
[0034] like Figures 4 to 5 As shown, the cable 300 includes a first segment 310 and a second segment 320. When the cable 300 is wound up, the first segment 310 of the cable 300 rotates relative to the second segment 320 of the cable 300. The first energized part 211 and the second energized part 212 rotate in the circumferential direction of the conductive cylinder 110, and the first energized part 211 and the second energized part 212 maintain contact with the conductive cylinder 110. Under the condition 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 mechanism, thereby preventing the cable 300 from getting tangled.
[0035] In some embodiments, such as Figure 1As shown, the first connector 100 further includes a conductive post 120, which is disposed inside the conductive cylinder 110, and an insulating gap is formed between the conductive post 120 and the inner wall 111 of the conductive cylinder 110 to prevent the conductive post 120 from contacting the conductive cylinder 110; the second connector 200 further includes a power-conducting post 220; when the conductive cylinder 110 is inserted into the receiving groove 213, the conductive post 120 and the power-conducting post 220 abut against each other to conduct electricity; the first power-conducting part 211 abuts against the inner wall 111 of the conductive cylinder 110, and an insulating gap is formed between the conductive post 120 and the inner wall 111 of the conductive cylinder 110, which can prevent the first power-conducting part 211 from accidentally contacting the conductive post 120, thereby preventing the occurrence of short circuit accidents. Both conductive post 120 and energized post 220 are made of conductive material. While maintaining power between conductive post 120 and energized post 220, conductive post 120 can rotate relative to energized post 220, which can reduce the risk of cable 300 tangling and improve the durability and power transmission stability of cable 300. Conductive post 120 is electrically connected to the first segment 310 of cable 300, and energized post 220 is electrically connected to the second segment 320 of cable 300. Current or signal can be transmitted through conductive post 120 and energized post 220, so that contact stability is maintained when cable 300 rotates or bends, and circuit breakage can be avoided. Conductive post 120 can use a special structure to reduce the stress when cable 300 is twisted.
[0036] In some embodiments, such as Figure 2 As shown, the conductive post 120 is located on the central axis of the conductive cylinder 110 to maximize the insulation gap between the conductive post 120 and the inner wall 111 of the conductive cylinder 110, thereby preventing short circuit accidents.
[0037] In some embodiments, the inner wall 111 and outer wall 112 of the conductive cylinder 110 are both made of conductive material, and an insulator 130 is provided between the inner wall 111 and outer wall 112 of the conductive cylinder 110. The insulator 130 is made of insulating material to prevent short circuit accidents. The first energized part 211 abuts against the inner wall 111 of the conductive cylinder 110, and the second energized part 212 abuts against the outer wall 112 of the conductive cylinder 110. The conductivity of the conductive material is usually measured by conductivity or resistivity. The higher the conductivity, the better the conductivity.
[0038] In some embodiments, such as Figure 2As shown, the first energized part 211 and the second energized part 212 are spring contacts; the ends of the first energized part 211 and the second energized part 212 are welded to the second segment 320 of the cable 300. Utilizing the elasticity of the spring contacts, the first energized part 211 and the second energized part 212 are more easily deformed and reset under force, thereby ensuring that the first energized part 211 and the second energized part 212 remain in contact with the conductive cylinder 110 to guarantee conductivity. The cable 300 contains three cores: a first core, a second core, and a third core. The inner wall 111 of the conductive cylinder 110 is welded to the first core of the first segment 310 of the cable 300, the outer wall 112 of the conductive cylinder 110 is welded to the second core of the first segment 310 of the cable 300, and the conductive post 120 is welded to the third core of the first segment 310 of the cable 300. The first energized part 211 is welded to the first core of the second segment 320 of the cable 300, the second energized part 212 is welded to the second core of the second segment 320 of the cable 300, and the energized post 220 is welded to the third core of the second segment 320 of the cable 300.
[0039] In some embodiments, such as Figure 2 As shown, at least one of the first energized portion 211 and the second energized portion 212 is partially bent to form a protruding section 215. The protruding section 215 protrudes towards the conductive cylinder 110 and is used to abut against the corresponding inner wall 111 or outer wall 112, which is more conducive to the electrical connection between the first energized portion 211 or the second energized portion 212 and the conductive cylinder 110. A clamping portion is formed between the first energized portion 211 and the second energized portion 212. The bent protruding end can strengthen the clamping force to ensure stable conduction between the first connector 100 and the second connector 200. The protruding section 215 may be formed on the first energized portion 211 or the second energized portion 212, or both the first energized portion 211 and the second energized portion 212 may be provided with a protruding section 215.
[0040] In some embodiments, such as Figure 4 As shown, the first connector includes a base 150, and a conductive cylinder 110 is fixed to the base 150; the second connector 200 includes a protective shell 230, which is sleeved on the outside of the housing 210, and the protective shell 230 and the base 150 are spirally connected. The protective shell 230 can play a protective role, preventing external dust, moisture, etc. from entering the interior of the connection mechanism, and playing a further waterproof role.
[0041] A second aspect of this utility model provides an underwater robot, comprising a robot body, a cable 300, and an anti-tangling connection mechanism provided in any of the first aspects of the present invention. A first connector 100 connects to a first segment 310 of the cable 300, and a second connector 200 connects to a 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 design and application of the anti-tangling cable 300 are key to ensuring the robot's efficient and safe operation. The underwater robot can adopt a streamlined shell to reduce the likelihood of protruding parts snagging on the cable 300.
[0042] If the anti-entanglement connection mechanism has the beneficial effects of the above embodiments, then the underwater robot will have the corresponding beneficial effects of the above embodiments. The specific implementation method can be referred to the above embodiments, and will not be repeated in this application.
[0043] The cable 300 may also include a third and a fourth segment. The connecting mechanism 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 mechanisms can be provided, and multiple connecting mechanisms can be set at different positions on the cable 300 to further reduce the probability of the cable 300 becoming tangled, twisted, or knotted during use.
[0044] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the embodiments.
