Description
Technical Field
[0001] This utility model relates to the field of cable connector technology, and in particular to a rotatable cable connector. Background Technology
[0002] A cable connector is a device used to connect cables to equipment or cables to each other, enabling stable transmission of current or signals. It is widely used in many fields such as power, electronics, and communications. Cable connectors are an important component of cable systems. They reliably connect different cables or cables to other electronic components and equipment through mechanical and electrical connections, ensuring stable and safe transmission of electrical energy and signals, while also facilitating the installation, maintenance, and replacement of equipment.
[0003] Firstly, most traditional cable connectors do not have a rotation function and cannot adapt to equipment that requires frequent rotation or angle adjustment. For example, in robotic arms, rotating equipment, or other situations where the cable direction needs to be flexibly adjusted, fixed connectors are prone to cable twisting, wear, and may even be damaged due to excessive stretching, affecting the normal operation and service life of the equipment.
[0004] Secondly, traditional cable connectors have poor sealing performance. In humid, dusty, or liquid-splashed environments, dust, moisture, and other impurities can easily enter the connector, causing short circuits, corrosion, or poor contact in conductive components, thereby reducing the reliability and safety of the connector. Summary of the Invention
[0005] This utility model is a rotatable cable connector proposed to overcome the shortcomings of the existing technology.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: A rotatable cable connector includes an insulating housing, a conductive communication element disposed within the insulating housing, conductive connectors disposed on both sides of the conductive communication element, a sealing rotating groove disposed on the outer side of the insulating housing, a sealing rotating ring rotatably connected to the inner side of the sealing rotating groove, a heat dissipation connecting ring disposed on one side of the sealing rotating ring, a protective housing detachably connected to one side of the heat dissipation connecting ring, an elastic sealing plate disposed on one side of the protective housing, a cable insertion hole disposed at the center of one side of the elastic sealing plate, and a plurality of storage holes disposed on the outer side of the protective housing, wherein cable limiting components are disposed within the storage holes.
[0007] Through the above technical solution, the conductive connection of the cable is achieved through the conductive communication body inside the insulating shell. The conductive connectors on both sides of the conductive communication body are used to connect with the external cable to ensure the transmission of current. The sealing rotating groove on the outside of the insulating shell cooperates with the sealing rotating ring to keep the connector sealed during rotation, preventing external dust and liquid from entering. The heat dissipation connecting ring is detachably connected to the protective shell for easy heat dissipation and maintenance. The cable insertion hole on the elastic sealing plate is used for cable insertion, while the cable limiting component in the storage hole on the outside of the protective shell is used to fix the cable and prevent it from loosening.
[0008] The design of the sealing rotating groove and sealing rotating ring ensures that the connector maintains good sealing performance during rotation, making it suitable for applications requiring frequent rotation, such as robotic arm cable connections. The detachable connection between the heat dissipation ring and the protective shell facilitates heat dissipation and maintenance, extending the connector's service life. The cable limiting component design effectively secures the cable, preventing it from loosening within the connector and improving connection stability.
[0009] Preferably, the conductive connector includes a conductive communication base, which is rotatably connected to one side of the conductive communication body. A plurality of conductive communication frames are provided on the side of the conductive communication base away from the conductive communication body. A cable core connection hole and a through hole are respectively provided on one side of the conductive communication frame. There are two through holes, which are respectively provided on both sides of the cable core connection hole. A clamping member is provided in the through hole.
[0010] Through the above technical solution, the conductive connector is rotatably connected to the conductive communication body through the conductive communication base. The conductive communication frame on the conductive communication base is provided with a cable core connection hole for connecting the cable core, and a through hole for installing a clamping component. The clamping component is used to press the cable core into the cable core connection hole to ensure a firm connection.
[0011] The clamping design effectively clamps the cable core, preventing it from loosening and improving connection reliability. The rotatable connection between the conductive communication base and the conductive communication body allows the conductive connector to adapt to cable connections at different angles, improving the connector's flexibility. The reasonable layout of the cable core connection holes and through holes on the conductive communication frame makes the connector structure compact and small in size.
[0012] Preferably, the clamping component includes a corrugated elastic rubber sleeve disposed in the through hole, with insulating pressure plates disposed at both ends of the corrugated elastic rubber sleeve, and a spring disposed between the two insulating pressure plates, the spring being placed inside the corrugated elastic rubber sleeve.
[0013] Through the above technical solution, the corrugated elastic rubber sleeve in the clamping component can generate elastic deformation when subjected to external force. Through the elastic force of spring one, the insulating pressure plate is pressed towards the cable core connection hole, thereby firmly fixing the cable core in the cable core connection hole.
[0014] The corrugated elastic rubber sleeve and spring design automatically adjust the clamping force according to the diameter of the cable core, adapting to cables of different specifications. The insulating pressure plate effectively isolates current, prevents short circuits, and improves the safety of the connector. The corrugated elastic rubber sleeve has good elasticity and wear resistance, enabling long-term stable operation and extending the service life of the clamping parts.
[0015] Preferably, the heat dissipation connecting ring has two threaded grooves on the side near the protective shell, and each of the two threaded grooves is threaded with an external threaded connecting ring, one side of which is connected to one side of the protective shell.
[0016] Through the above technical solution, the threaded groove on the heat-dissipating connecting ring is connected to the external threaded connecting ring by threads, and one side of the external threaded connecting ring is connected to the protective shell, realizing the detachable connection between the heat-dissipating connecting ring and the protective shell. This connection method facilitates the installation and disassembly of the heat-dissipating connecting ring, and facilitates heat dissipation and maintenance.
[0017] The heat dissipation ring design effectively dissipates heat, reduces the temperature of the connector during operation, and improves its performance and service life. The detachable connection method makes the installation and removal of the heat dissipation ring more convenient, facilitating maintenance and replacement. The threaded connection structure is stable and ensures a firm and reliable connection between the heat dissipation ring and the protective shell.
[0018] Preferably, the cable limiting component includes a threaded rod that is threadedly connected to the receiving groove. One end of the threaded rod is provided with a protrusion, and the other end of the threaded rod is provided with a groove. An extension rod is slidably connected in the groove. A second spring is provided at the end of the extension rod near the groove, and an arc-shaped friction block is provided at the end of the extension rod away from the groove.
[0019] Through the above technical solution, the cable limiting component is threadedly connected to the receiving hole via a threaded rod. The protrusion at one end of the threaded rod is used to limit its position, and an extension rod is slidably connected in the groove at the other end. The extension rod, through the elastic force of spring two, presses the arc-shaped friction block against the cable surface, thereby achieving the limiting and fixing of the cable.
[0020] The arc-shaped friction block design allows for close contact with the cable surface. The elastic force of spring two ensures the cable's stability within the connector, preventing loosening. The elastic design of spring two can accommodate cables of different diameters, improving the versatility of the cable limiting component. The threaded connection between the threaded rod and the receiving hole allows for adjustment of the cable limiting component's position, facilitating adjustments based on the actual cable position.
[0021] In summary, this utility model, by setting a sealing rotating groove and a sealing rotating ring on the outside of the insulating shell, enables the connector to maintain good sealing performance during rotation, effectively preventing external impurities such as dust and liquid from entering the interior, thereby improving the reliability and durability of the connector. It is especially suitable for harsh environments such as humid and dusty environments. The rotating connection design of the sealing rotating ring and the sealing rotating groove allows the connector to rotate flexibly, meeting the cable direction adjustment needs in different scenarios. For example, in occasions where frequent rotation is required, such as in robotic arms and rotating equipment, it can ensure the stability of the cable connection and avoid damage caused by cable twisting.
[0022] The design of this heat dissipation connecting ring effectively increases the heat dissipation area of the connector. The detachable connection with the protective shell facilitates air circulation, thereby improving heat dissipation efficiency, reducing the temperature of the connector during operation, extending its service life, and ensuring the performance stability of the connector under high load or long-term operation. The detachable connection between the heat dissipation connecting ring and the protective shell makes the installation and removal of the heat dissipation connecting ring more convenient, facilitating regular maintenance, cleaning, or replacement of components inside the connector, and reducing maintenance costs and repair time.
[0023] This utility model discloses a cable limiting component that, through a combination of a threaded rod, a second spring, and an arc-shaped friction block, can firmly fix the cable within the protective shell. The elasticity of the second spring ensures that the arc-shaped friction block closely adheres to the cable surface, preventing the cable from loosening or shifting within the connector. This improves the stability of the cable connection and avoids poor contact or damage caused by cable movement. The elastic design of the cable limiting component can accommodate cables of different diameters. By adjusting the compression of the second spring, various cable specifications can be fixed, improving the connector's versatility and applicability, and reducing the user's operating costs in different cable connection scenarios.
[0024] The clamping component in this conductive connector adopts a structure of corrugated elastic rubber sleeve, insulating pressure plate and spring one, which can effectively clamp the cable core. The elastic force of spring one makes the cable core in close contact with the conductive communication frame, ensuring the stability and reliability of current transmission. At the same time, the insulating pressure plate can prevent current leakage and improve the safety of the connection.
[0025] The conductive communication base and the conductive communication body are connected by a rotating mechanism, which allows the conductive connector to be flexibly adjusted according to the connection angle of the cable, adapting to cable access in different directions and enhancing the applicability and flexibility of the connector in complex installation environments.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0029] like Figures 1-6 As shown, a rotatable cable connector includes an insulating shell 1, a conductive communication body 2, a conductive connector 3, a clamping member 4, a sealing rotating groove 5, a sealing rotating ring 6, a heat dissipation connecting ring 7, a protective shell 8, an elastic sealing plate 9, a cable insertion hole, a threaded groove 10, an external threaded connecting ring 11, and a cable limiting member 12.
[0030] The insulating housing 1 is the main structure of the entire connector. It is made of insulating material to protect the internal conductive components and prevent short circuits. The interior of the insulating housing 1 is hollow to accommodate the conductive communication body 2 and other related components.
[0031] The conductive communication element 2 is disposed inside the insulating housing 1 and is used to realize the electrical connection between cables. Conductive connectors 3 are provided on both sides of the conductive communication element 2 for connecting with external cables.
[0032] The conductive connector 3 includes a conductive communication base 31 and several conductive communication frames 32. The conductive communication base 31 is rotatably connected to one side of the conductive communication body 2 and can be adjusted at an angle as needed. The conductive communication frames 32 are located on the side of the conductive communication base 31 away from the conductive communication body 2, and each side of the frame has a cable core connection hole 33 and a through hole 34. The cable core connection hole 33 is used to insert the cable core, and the through hole 34 is provided with a clamping member 4 to fix the cable core and ensure the connection is secure.
[0033] The clamping component 4 includes a corrugated elastic rubber sleeve 41, an insulating pressure plate 42, and a spring 43. The corrugated elastic rubber sleeve 41 is disposed in the through hole 34, and an insulating pressure plate 42 is disposed at both ends of the sleeve. A spring 43 is disposed between the two insulating pressure plates 42 and is placed inside the corrugated elastic rubber sleeve 41.
[0034] When the cable core is inserted into the cable core connection hole 33, the elastic force of the spring 43 presses the cable core tightly through the insulating pressure plate 42, ensuring the stability and reliability of the connection. At the same time, the corrugated elastic rubber sleeve 41 can provide a certain buffering effect to prevent the cable core from being damaged by excessive compression.
[0035] The outer side of the insulating housing 1 is provided with a sealing rotating groove 5, and the inner side of the sealing rotating groove 5 is rotatably connected with a sealing rotating ring 6. The sealing rotating ring 6 can rotate freely in the sealing rotating groove 5, and at the same time, the sealing structure such as the sealing ring or the sealing adhesive maintains the sealing of the connector, preventing external dust, moisture and other impurities from entering, and ensuring the reliability of the connector in humid or harsh environments.
[0036] A heat dissipation connecting ring 7 is provided on one side of the sealing rotating ring 6. One side of the heat dissipation connecting ring 7 is connected to the protective shell 8 by a detachable connection. The heat dissipation connecting ring 7 is made of a material with good heat dissipation performance. Its surface can be provided with heat dissipation fins and other structures to increase the heat dissipation area and reduce the temperature of the connector during operation. The protective shell 8 is used to further protect the internal components of the connector and provide external protection.
[0037] A spring-loaded sealing plate 9 is provided on one side of the protective shell 8. A cable insertion hole is provided at the center of one side of the spring-loaded sealing plate 9. The spring-loaded sealing plate 9 is made of elastic material and can automatically seal the gap around the cable insertion hole when the cable is inserted, further enhancing the sealing performance of the connector, while allowing the cable to pass through smoothly.
[0038] The heat dissipation connecting ring 7 has two threaded grooves 10 on the side near the protective shell 8. Both threaded grooves 10 are threaded with external threaded connecting rings 11, and one side of the external threaded connecting ring 11 is connected to one side of the protective shell 8.
[0039] The outer side of the protective shell 8 is provided with several storage holes, and a cable limiting component 12 is provided in the storage holes. The cable limiting component 12 includes a threaded rod 121, a protrusion 122, a groove, an extension rod 124, a second spring 123, and an arc-shaped friction block 125. The threaded rod 121 is threadedly connected in the storage hole. One end of the threaded rod 121 is provided with a protrusion 122 to limit the position of the threaded rod 121; the other end is provided with a groove, in which the extension rod 124 is slidably connected. The end of the extension rod 124 near the groove is provided with a second spring 123. The second spring 123 provides elastic force, so that the arc-shaped friction block 125 at the end of the extension rod 124 away from the groove can tightly fit against the cable surface, thereby limiting and fixing the cable and preventing the cable from loosening or shifting in the connector.
[0040] In this embodiment, the cable connection is as follows: the cable core is inserted into the cable core connection hole 33 of the conductive connector 3, and the cable core is pressed by the spring 43 and the insulating pressure plate 42 in the clamping member 4 to ensure a firm and reliable connection.
[0041] Cable fixing: The cable is passed through the cable insertion hole of the elastic sealing plate 9. The elastic sealing plate 9 automatically seals the gaps around the cable, and the cable is fixed inside the protective shell 8 by the arc-shaped friction block 125 in the cable limiting component 12. Specifically, the threaded rod 121 is rotated, causing the extension rod 124 to extend outward under the elastic force of the spring 123. The arc-shaped friction block 125 tightly fits against the cable surface, thereby achieving the limiting and fixing of the cable.
[0042] Heat dissipation and maintenance: The heat dissipation ring 7 increases the heat dissipation area through its surface heat dissipation fins and other structures, reducing the temperature of the connector during operation. When maintenance or replacement of parts is required, the heat dissipation ring 7 and the protective shell 8 can be disassembled for easy cleaning and replacement of internal parts.
[0043] Rotation operation: When it is necessary to adjust the cable direction, the connector can be rotated flexibly by rotating the sealing rotating ring 6 in the sealing rotating groove 5, while maintaining the sealing performance.
[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
