Description

Technical Field

[0001] This utility model relates to the field of wire harness connection technology, and in particular to an anti-tangle wire harness rotary connector. Background Technology

[0002] Wire harness connectors are key components used to achieve electrical connections between wire harnesses and between wire harnesses and electrical equipment. They are also known as wire harness connectors and play an important role in many fields such as automobiles and electronic equipment. They can ensure the stable transmission of current or signals between different circuits, avoid short circuits and open circuits caused by direct exposure of wires or poor contact, and provide a certain degree of mechanical protection for wire harnesses, facilitating the installation, maintenance and replacement of wires.

[0003] Existing technologies have obvious mechanical structural defects in the design of anti-tangle wire harnesses. Traditional wire harness rotary connectors usually adopt a fixed connection method. When the wire harness rotates, it is easy for the wire harness to continue to tangle and eventually get knotted. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an anti-tangle wire harness rotary connector, which aims to improve the existing technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-tangle wire harness rotary connector, comprising a protective shell, a first connecting ring rotatably connected to the left inner wall of the protective shell, an insulating layer attached to the inner wall of the first connecting ring, a wire harness body fixedly connected to the inner wall of the insulating layer, a spring sleeved on the surface of the insulating layer, a second connecting ring fixedly connected to the right end of the spring, the second connecting ring rotatably connected to the inner wall of the protective shell, a sealing ring attached to the left side of the insulating layer, the sealing ring fixedly connected to the inner wall of the protective shell, a conductive ring attached to the right surface of the sealing ring, a second limiting ring fixedly connected to the surface of the conductive ring, the left surface of the second limiting ring fitting against the right surface of the protective shell, and a fixing mechanism provided on the surface of the wire harness body.

[0006] Through the above technical solution, with the dual protection of threaded connection and flexible material, even if there is severe vibration or external pulling during equipment operation, the main body of the wire harness can still be firmly fixed in the connector, avoiding connection failure caused by loose wire harness, and effectively improving the safety and reliability of equipment operation.

[0007] Preferably, the fixing mechanism includes a first limiting ring, the inner wall of the first limiting ring being in contact with the surface of the wire harness body, a fixing ring being threadedly connected to the inner wall of the first connecting ring, a flexible connecting ring being in contact with the inner wall of the fixing ring, and a first screw and a second screw being threadedly connected to the right side of the first limiting ring.

[0008] Preferably, the right side surface of the fixing ring is provided with a first rigid connecting groove and a second rigid connecting groove, the first screw is threadedly connected to the inner wall of the first rigid connecting groove, and the second screw is threadedly connected to the inner wall of the second rigid connecting groove.

[0009] Through the above technical solution: in practical applications, when the main body of the wire harness rotates, the rigid connection between the rigid connecting groove and the first screw can effectively transmit torque, ensuring that the fixing ring and the first limiting ring rotate synchronously, and preventing the wire harness from twisting at the fixed part.

[0010] Preferably, a connecting protrusion is fixedly connected to the right side surface of the protective shell, and a conical ring is fixedly connected to the right side of the connecting protrusion, with the inner wall of the conical ring being fixedly connected to the surface of the conductive ring.

[0011] Through the above technical solution, the conductive ring achieves a mechanical connection with the protective shell through the fixed connection between the tapered ring and the connecting convex ring, while maintaining good conductivity.

[0012] Preferably, the right end of the first connecting ring is fixedly connected to the spring, and the left surface of the conductive ring is in contact with the right surface of the wire harness body.

[0013] The above technical solution allows for the removal of oxide layers and impurities through the relative sliding between the conductive terminals and the surface of the conductive ring during rotation, thereby reducing contact resistance and ensuring the stability of signal transmission.

[0014] Preferably, the insulating layer is made of silicone rubber, and the conductive ring is made of a highly conductive metal.

[0015] Through the above technical solutions: the flexible insulating material attenuates the mechanical rotational force through elastic deformation, avoiding excessive twisting of the wire harness body; the conductive metal material ensures continuous transmission of electrical signals during rotation through its highly conductive and wear-resistant surface.

[0016] Preferably, the right side surface of the flexible connecting ring is provided with a first flexible connecting groove and a second flexible connecting groove, the first screw is threadedly connected to the inner wall of the first flexible connecting groove, and the second screw is threadedly connected to the inner wall of the second flexible connecting groove.

[0017] The above technical solution combines the elastic deformation capability provided by the flexible connecting groove with the stable support of the rigid connecting groove, which can not only adapt to the slight positional deviation of the wire harness body during installation, but also provide sufficient connection strength after fixing.

[0018] Preferably, the inner wall of the flexible connecting ring is in contact with the surface of the wire harness body, and the right side surface of the first limiting ring is in contact with both the left side surfaces of the flexible connecting ring and the fixing ring.

[0019] Through the above technical solution, the main body of the wire harness is well supported and protected inside the connector, and can remain stable even under high-speed rotation or severe vibration conditions, thereby improving the reliability and stability of the entire connector.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the rotation of the main body of the wire harness is transmitted to the first connecting ring through the combined action of the fixing ring, the first connecting ring, the spring and the second connecting ring, and the rotational force is reduced by the spring and the second connecting ring. At the same time, the right conductive ring is attached to the left end of the main body of the wire harness, so that the main body of the wire harness remains connected in the rotating state, thereby extending the service life of the wire harness and reducing equipment downtime and maintenance caused by wire harness failure.

[0022] 2. In this utility model, the connecting grooves on the surfaces of the flexible connecting ring and the fixed ring are aligned one to one, and the first screw and the second screw are screwed into the connecting grooves to fix the flexible connecting ring and the fixed ring together. Due to the large friction between the flexible connecting ring and the wire harness body, the wire harness body can be quickly fixed. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figures 1-3 An embodiment of this utility model provides an anti-tangle wire harness rotary connector, including a protective shell 1, a first connecting ring 5 rotatably connected to the left inner wall of the protective shell 1, an insulating layer 7 attached to the inner wall of the first connecting ring 5, a wire harness body 2 fixedly connected to the inner wall of the insulating layer 7, a spring 6 sleeved on the surface of the insulating layer 7, a second connecting ring 8 fixedly connected to the right end of the spring 6, the second connecting ring 8 rotatably connected to the inner wall of the protective shell 1, a sealing ring 9 attached to the left side of the insulating layer 7, the sealing ring 9 fixedly connected to the inner wall of the protective shell 1, a conductive ring 3 attached to the right surface of the sealing ring 9, a second limiting ring 20 fixedly connected to the surface of the conductive ring 3, the left surface of the second limiting ring 20 attached to the right surface of the protective shell 1, and a fixing mechanism provided on the surface of the wire harness body 2;

[0031] Specifically, the first connecting ring 5, which is rotatably connected to the inner wall of the protective shell 1, can rotate with the rotation of the main body 2 of the wire harness. The insulating layer 7 attached to the inner wall can both isolate the current and buffer the impact force when the wire harness rotates. The right end of the spring 6 sleeved on the surface of the insulating layer 7 is fixed to the second connecting ring 8, so that the second connecting ring 8 and the inner wall of the protective shell 1 form a rotatable connection structure. When the main body 2 of the wire harness generates rotational force, the spring 6 can absorb part of the torque through deformation, avoiding the direct transmission of torque and causing the wire harness to entangle. The sealing ring 9 is fixedly connected to the protective shell 1 and attached to the left side of the insulating layer 7. The conductive ring 3 on its right side abuts against the right side surface of the protective shell 1 through the second limiting ring 20. This layout not only ensures the stable electrical connection between the conductive ring 3 and the main body 2 of the wire harness, but also improves the dustproof and waterproof performance of the connector through the sealing ring 9.

[0032] Reference Figure 4 The fixing mechanism includes a first limiting ring 4, the inner wall of the first limiting ring 4 is in contact with the surface of the wire harness body 2, the inner wall of the first connecting ring 5 is threaded with a fixing ring 13, the inner wall of the fixing ring 13 is in contact with a flexible connecting ring 12, and the right side of the first limiting ring 4 is threaded with a first screw 14 and a second screw 15.

[0033] Specifically, the inner wall of the first limiting ring 4 is attached to the surface of the wire harness body 2 to initially limit the position of the wire harness and prevent it from shifting during installation. The threaded structure on the inner wall of the first connecting ring 5 matches the external thread of the fixing ring 13, so that the fixing ring 13 can be firmly screwed into the first connecting ring 5. This facilitates installation and disassembly and provides reliable axial positioning after fixing, ensuring that the fixing ring 13 and the first connecting ring 5 will not easily slip relative to each other.

[0034] Reference Figure 4 The right side surface of the fixing ring 13 is provided with a first rigid connecting groove 17 and a second rigid connecting groove 19. The first screw 14 is threadedly connected to the inner wall of the first rigid connecting groove 17, and the second screw 15 is threadedly connected to the inner wall of the second flexible connecting groove 19.

[0035] Specifically, the first rigid connecting groove 17 is made of rigid material, and the threaded structure on its inner wall matches the external thread of the first screw 14, which can effectively resist the lateral shear force generated by the rotation or vibration of the wire harness, and ensure the connection stability between the fixing ring 13 and the first limiting ring 4.

[0036] Reference Figures 1-2 A connecting protrusion ring 10 is fixedly connected to the right side surface of the protective shell 1, and a conical ring 11 is fixedly connected to the right side of the connecting protrusion ring 10. The inner wall of the conical ring 11 is fixedly connected to the surface of the conductive ring 3.

[0037] Specifically, the connecting convex ring 10 and the conical ring 11 can provide support and protection for the conductive ring 3. By fixing the connecting convex ring 10 to the protective shell, external dust and liquid can be effectively prevented from seeping into the internal structure from the connection point.

[0038] Reference Figures 2-3 The right end of the first connecting ring 5 is fixedly connected to the spring 6, and the left surface of the conductive ring 3 is in contact with the right surface of the wire harness body 2;

[0039] Specifically, the spring 6 can absorb the rotational torque of the main body 2 of the wire harness while transmitting an appropriate amount of rotational force to the second connecting ring 8, thereby achieving a gradual decrease in torque. In actual operation, when the main body 2 of the wire harness rotates clockwise, the spring 6 will undergo a spiral deformation due to the force. This deformation can not only buffer the rotational force, but also convert some energy into elastic potential energy for storage. When the main body 2 of the wire harness rotates in the opposite direction, the stored elastic potential energy can be released to assist the main body 2 of the wire harness in turning smoothly and reduce the damage to the internal structure of the connector caused by inertial impact.

[0040] Reference Figure 3 The insulating layer 7 is made of silicone rubber, and the conductive ring 3 is made of highly conductive metal.

[0041] Specifically, silicone rubber has good flexibility and aging resistance, and is not easy to crack during long-term rotational deformation. It has high insulation resistance and low dielectric loss, which can effectively isolate the electrical connection between the wire harness body 2 and the external structure. The highly conductive metal material can reduce contact resistance and enhance corrosion resistance, ensuring a stable electrical connection with the conductive terminals of the wire harness body 2.

[0042] Reference Figure 4 The right side surface of the flexible connecting ring 12 is provided with a first flexible connecting groove 16 and a second flexible connecting groove 18. The first screw 14 is threadedly connected to the inner wall of the first flexible connecting groove 16, and the second screw 15 is threadedly connected to the inner wall of the second flexible connecting groove 18.

[0043] Specifically, the flexible connecting groove on the right side surface of the flexible connecting ring 12 uses threaded teeth with elastic deformation capability. When the first screw 14 and the second screw 15 are screwed in, the flexible material will undergo slight deformation under the compression of the threads, thereby increasing the contact area between the threads and improving the stability of the connection.

[0044] Reference Figures 2-3 The inner wall of the flexible connecting ring 12 is in contact with the surface of the wire harness body 2, and the right side surface of the first limiting ring 4 is in contact with both the flexible connecting ring 12 and the left side surface of the fixing ring 13.

[0045] Specifically, the inner wall of the flexible connecting ring 12 is provided with an anti-wear layer on the contact surface with the wire harness body 2. The inner wall is uniformly distributed with fine elastic protrusions. When these protrusions come into contact with the wire harness body 2, they will produce slight deformation, thereby increasing the contact area and friction. This can effectively prevent the wire harness from shaking in the radial direction and absorb the slight displacement of the wire harness in the axial direction through elastic deformation, thus avoiding damage to the wire harness skin caused by rigid contact.

[0046] Working principle: After the wire harness body 2 enters the flexible connecting ring 12, the connecting grooves on the surfaces of the flexible connecting ring 12 and the fixed ring 13 are aligned one after another. The first screw 14 and the second screw 15 are screwed into the connecting grooves to fix the flexible connecting ring 12 and the fixed ring 13 together. Since the flexible connecting ring 12 is made of flexible material, there is a large friction between the flexible connecting ring 12 and the wire harness body 2, thereby achieving rapid fixation of the wire harness body 2.

[0047] After the main body 2 of the wire harness is fixed on the fixing mechanism, it is threadedly connected to the first connecting ring 5 through the fixing ring 13. The first connecting ring 5 is rotatably connected to the protective shell 1, and the first connecting ring 5 is connected to the second connecting ring 8 through the spring 6, so that the rotation of the main body 2 of the wire harness is transmitted to the first connecting ring 5. At the same time, the spring 6 and the second connecting ring 8 are used to reduce the rotational force. Meanwhile, the right conductive ring 3 is attached to the left end of the main body 2 of the wire harness, so that the main body 2 of the wire harness remains connected in the rotating state. This ensures that the connector can avoid the main body 2 of the wire harness from knotting, wearing or even breaking due to continuous twisting, thus extending the service life of the wire harness and reducing equipment downtime and maintenance caused by wire harness failure.

[0048] In addition, the insulation layer 7 is also made of flexible material, which can further reduce the rotational force of the wire harness body 2.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
