Description

Technical Field

[0001] This application relates to the technical field of cable connection, and particularly relates to a cable joint fastening structure and an automatic installation device. Background Art

[0002] In the actual application of cables, connectors are usually equipped at their ends. The connector mainly consists of a connection part and a fastening part. The main function of the connection part is to achieve effective insertion of the cable wire with other components, while the fastening part is responsible for firmly fixing the connection part on the cable body. Currently, the fastening part generally adopts a threaded connection method to ensure reliable clamping and fixing of the connection part.

[0003] However, for the above technical solution, in the actual application process, the cable joint may face the pressure exerted by the external environment. This pressure may cause the fastening part to rotate, which will have an adverse effect on the fastening effect of the cable joint. Summary of the Invention

[0004] To improve the above problems, this application provides a cable joint fastening structure and an automatic installation device.

[0005] In the first aspect, this application provides a cable joint fastening structure, adopting the following technical solution: A cable joint fastening structure is installed on a cable joint, including: A connection ring is fixedly installed on the cable joint, and the inner wall of the connection ring contacts the outer peripheral wall of the cable. Connection bars are fixedly installed on the connection ring and are evenly spaced along the circumferential direction of the connection ring. A plurality of the connection bars all contact the outer peripheral wall of the cable. A fixing ring is threadedly connected to the connection bar. A protective sleeve is coaxially sleeved on the connection ring, and the connection bar is also located inside the protective sleeve. A positioning component is installed between the protective sleeve and the connection ring to rotatably mount the protective sleeve on the connection ring.

[0006] By adopting the above technical solution, the connection ring and the connection bars closely fit the outer peripheral wall of the cable to provide a preliminary fixing effect. The fixing ring is threadedly connected to the connection bar, making the connection bar tightly adhere to the cable, increasing the fastening effect between the joint and the cable. The protective sleeve provides an additional protective layer, so that the fixing ring is not directly exposed to the outside. The protective sleeve can rotate relative to the fixing ring through the positioning component. If an external force is applied to the protective sleeve, the protective sleeve rotates, which can not only protect the fixing ring but also have a buffering effect on the external force, enabling the cable joint to maintain a good fastening effect.

[0007] Optionally, the positioning component includes: The first positioning rod, one end of the first positioning rod is fixedly installed on the inner wall of the protective sleeve, and a plurality of them are circumferentially spaced along the protective sleeve. The second positioning rod, one end is connected to the other end of the first positioning rod, and the other end is fixedly connected to the inner wall of the protective sleeve. An angle less than 180° is formed between the first positioning rod and the second positioning rod. The positioning block is provided with a through hole. The connection part of the first positioning rod and the second positioning rod is located in the through hole. The positioning block is rotatably installed at the connection part of the first positioning rod and the second positioning rod. When the fixing ring is threadedly installed in the protective sleeve, the positioning block contacts the outer wall of the fixing ring.

[0008] The positioning assembly further includes a third positioning rod. One end of the third positioning rod is rotatably installed on the positioning block, and the other end contacts the connection ring. A elastic member is installed on the positioning block to always drive the other end of the third positioning rod to approach the connection ring.

[0009] By adopting the above technical solutions, when the fixing ring is rotatably installed on the connecting strip, since the first positioning rod and the second positioning rod form an angle less than 180°, the axial direction of the protective sleeve is limited, and the protective sleeve rotates stably along its own central axis relative to the positioning block; when the fixing ring is not installed on the connecting strip, it can first slide into the protective sleeve. The protective sleeve contacts the connection ring through the third positioning rod. The elastic member drives the third positioning rod to stably abut against the connection ring, so that the protective sleeve and the connection ring maintain a stable coaxial relationship. When the fixing ring is installed on the connection ring and is located in the protective sleeve, the third positioning rod presses against the outer wall of the fixing ring. The third positioning rod improves the stability of the positioning block and can also make the protective sleeve and the positioning block maintain a stable sliding relationship.

[0010] Optionally, the elastic member is a torsion spring.

[0011] By adopting the above technical solutions, the torsion spring as the elastic member provides continuous and adjustable elastic force, ensuring that the third positioning rod always has a tendency to approach the connection ring, and enhancing the self - adaptability and fastening effect of the structure.

[0012] Optionally, the positioning block is a spherical structure, and the positioning block is tangent to the outer wall of the fixing ring.

[0013] By adopting the above technical solutions, the spherical positioning block can adapt to the curved surface of the fixing ring, reduce the contact stress, improve the wear resistance, and at the same time ensure the stable contact between the positioning block and the fixing ring, enhancing the stability of the structure.

[0014] Optionally, a convex block is detachably installed at the end of the fixing ring. The convex block is located outside the protective sleeve, and a plurality of convex blocks are distributed circumferentially along the fixing ring.

[0015] By adopting the above technical solution, the design of the bump facilitates the grasping and fixing by external tools or devices (such as the clamping blocks of automatic installation equipment), improves the convenience of installation and disassembly, and especially in the automated installation process, the bump simplifies the operation process as an interface point.

[0016] In a second aspect, the present application provides an automatic cable joint installation device, adopting the following technical solution: An automatic cable joint installation device for installing the above cable joint fastening structure, comprising: An installation table, A plurality of clamping blocks installed on the installation table for connecting with the bumps, A driving member for driving the plurality of clamping blocks to approach or move away from each other; A transmission assembly for driving the plurality of clamping blocks to rotate synchronously, A guide seat, and the protective sleeve is horizontally slidably installed on the guide seat.

[0017] By adopting the above technical solution, the automatic installation device realizes the rapid and accurate installation of the cable joint fastening structure through the cooperation of the clamping blocks and the bumps. The coordinated work of the driving member and the transmission assembly improves the installation efficiency and accuracy, and the guide seat ensures the stable sliding of the protective sleeve during the installation process, overall improving the automation level.

[0018] Optionally, the driving member includes a plurality of servo electric cylinders, and the output shafts of the servo electric cylinders are fixedly connected to the clamping blocks.

[0019] By adopting the above technical solution, the servo electric cylinders provide precise position control and force control, ensuring the stability and accuracy of the clamping blocks during grasping and installation, and improving the reliability and efficiency of the automatic installation device.

[0020] Optionally, the transmission assembly includes a driving gear and a transmission gear that mesh with each other, and a power source for driving the driving gear to rotate. The transmission gear is provided with an installation groove, and the plurality of servo electric cylinders are circumferentially distributed along the installation groove.

[0021] By adopting the above technical solution, the synchronous rotation of the plurality of clamping blocks is realized through the meshing of the driving gear and the transmission gear, improving the coordination and consistency during the installation process. The design of the installation groove facilitates the arrangement and fixation of the servo electric cylinders, enhancing the compactness and integration of the structure.

[0022] Optionally, the guide seat is provided in two semi-parts, and the guide seat is spliced to form a guide groove, and the protective sleeve is slidably installed in the guide groove.

[0023] By adopting the above technical solutions, the guiding seats arranged in pairs are convenient for disassembly and assembly, meeting the installation requirements of cable joint fastening structures of different sizes or types. The design of the guiding grooves ensures the stability and accuracy of the protective sleeve during the sliding process, improving the smoothness and efficiency of the installation process.

[0024] In summary, the present application includes at least one of the following beneficial effects: 1. The protective sleeve provides an additional protective layer, reducing the risk of the fixing ring being directly exposed to the external environment, and allowing the protective sleeve to rotate relative to each other through the positioning component, buffering external forces and maintaining the fastening effect; 2. The automatic installation device cooperates with the bumps on the fixing ring through the clamping blocks, and combines the driving member and the transmission component to achieve the rapid and precise installation of the cable joint fastening structure.

Specific implementation manners

[0027] The following further elaborates on this application in conjunction with the attached Figures 1 - 8 drawings.

[0028] The present invention relates to a cable joint fastening structure and its automatic installation equipment, aiming to provide a technical solution that can enhance the fastening stability, protection performance of the cable joint, and improve the automation installation efficiency and accuracy.

[0029] In a first aspect, this implementation manner provides a cable joint fastening structure for installation on a cable 200 joint, mainly including a connecting ring 10, connecting bars 20, a fixing ring 30, a protective sleeve 40, and a positioning assembly 50.

[0030] Referring to Figure 1 , one end of the connecting ring 10 is fixedly installed on the cable 200 joint. The connecting ring 10 has a perforation for the cable 200 to pass through. The inner wall of the connecting ring 10 is in close contact with the outer peripheral wall of the cable 200, providing a preliminary fixing effect. The connecting bars 20 are evenly spaced along the circumferential direction of the connecting ring 10 and are in contact with the outer peripheral wall of the cable 200, further enhancing the fixing effect.

[0031] Referring to Figure 2 and Figure 3 , the fixing ring 30 is connected to the connecting bars 20 by threads, further pressing the connecting bars 20 to ensure the fastening of the cable 200 joint. The protective sleeve 40 is coaxially sleeved on the connecting ring 10, covering the fixing ring 30 and the connecting bars 20, providing an additional protective layer. The positioning assembly 50 is installed between the protective sleeve 40 and the connecting ring 10, enabling the protective sleeve 40 to rotate relative to the connecting ring 10 to buffer external pressure and maintain the fastening effect. One axial end of the protective sleeve 40 is in fitting contact with the cable 200 joint, and a retaining ring 41 extends from the other axial end of the protective sleeve 40. The inner diameter of the retaining ring 41 is smaller than the inner diameter of the protective sleeve 40.

[0032] Referring to Figure 3, the positioning component 50 includes a first positioning rod 51, a second positioning rod 52, a positioning block 53 and a third positioning rod 54. One end of the first positioning rod 51 is fixedly installed on the inner wall of the protective sleeve 40, and a plurality of them are circumferentially spaced along the protective sleeve 40. One end of the second positioning rod 52 is connected to the other end of the first positioning rod 51, and the other end is fixedly connected to the inner wall of the protective sleeve 40. An angle less than 180° is formed between the first positioning rod 51 and the second positioning rod 52. The positioning block 53 is provided with a through hole. The connection part of the first positioning rod 51 and the second positioning rod 52 is located in the through hole. The first positioning rod 51 and the second positioning rod 52 respectively extend obliquely from both ends of the through hole. There is a gap between the positioning block 53 and both the protective sleeve 40 and the connecting ring 10. When the fixing ring 30 is threadedly installed in the protective sleeve 40, one end of the fixing ring 30 abuts against the end of the cable 200 connector. The positioning block 53 contacts the outer wall of the fixing ring 30, and the outer peripheral side wall of the fixing ring 30 contacts the inner wall of the retaining ring 41. A limiting ring 31 is fixedly installed on the outer peripheral side wall of the fixing ring 30, and the end of the limiting ring 31 fits with the end of the retaining ring 41.

[0033] The positioning block 53 has a spherical structure and is tangent to the outer wall of the fixing ring 30. The spherical positioning block 53 can adapt to the curved surface of the fixing ring 30, reduce the contact stress, and improve the wear resistance. When the fixing ring 30 is rotatably installed on the connecting strip 20, the positioning block 53 contacts the outer wall of the fixing ring 30 to ensure that the protective sleeve 40 rotates stably along its own central axis relative to the positioning block 53.

[0034] Referring to Figure 4 and Figure 5 , one end of the third positioning rod 54 is rotatably installed on the positioning block 53, and the other end contacts the connecting ring 10. A elastic member (such as a torsion spring 55) that drives the other end of the third positioning rod 54 to always approach the connecting ring 10 is installed on the positioning block 53. One end of the torsion spring 55 is fixed on the positioning block 53, and the other end contacts the third positioning rod 54. The pre-tightening force of the torsion spring 55 is set so that the third positioning rod 54 always maintains a slight pressing force on the connecting ring 10 without external force. The continuous elastic force provided by the torsion spring 55 ensures that the third positioning rod 54 always closely adheres to the connecting ring 10. Under the action of the torsion spring 55, the third positioning rod 54 ensures that the protective sleeve 40 and the connecting ring 10 maintain a stable coaxial relationship.

[0035] During the process of the threaded connection between the fixing ring 30 and the connecting strip 20, when the fixing ring 30 contacts the third positioning rod 54, it has the effect of squeezing the torsion spring 55, causing the third positioning rod 54 to rotate upward. When the fixing ring 30 is installed on the connecting ring 10 and is located in the protective sleeve 40, the positioning block 53 is tangent to the outer wall of the fixing ring 30, and the third positioning rod 54 presses against the outer wall of the fixing ring 30, further improving the stability of the protective sleeve 40 and the positioning block 53.

[0036] Since the first positioning rod 51 and the second positioning rod 52 form an angle less than 180°, the axial direction of the protective sleeve 40 is defined, and the protective sleeve 40 rotates stably along its own central axis relative to the positioning block 53, and the first positioning rod 51 and the second positioning rod 52 rotate relative to the positioning block 53.

[0037] Referring to Figure 6 , a convex block 32 is detachably installed at the end of the fixing ring 30. The convex block 32 is located outside the protective sleeve 40 and a plurality of convex blocks 32 are distributed circumferentially along the fixing ring 30. The design of the convex block 32 facilitates the grasping and fixing of external tools or devices (such as the clamping block 70 of the automatic installation device), improving the convenience of installation and disassembly.

[0038] The implementation principle of a cable joint fastening structure in an embodiment of the present application is as follows: Through the synergistic effect of the connecting ring 10, the connecting strip 20 and the fixing ring 30, the firm fixing of the cable 200 joint is realized. The connecting ring 10 closely fits the outer wall of the cable 200, the connecting strips 20 are evenly distributed along the circumference of the connecting ring 10 and contact the outer wall of the cable 200, and the fixing ring 30 presses the connecting strips 20 through threaded connection to further enhance the fastening effect. The protective sleeve 40 is sleeved on the connecting ring 10, covering the fixing ring 30, providing external protection, and enabling the protective sleeve 40 to rotate relative to the connecting ring 10 through the positioning assembly 50 to buffer external pressure and prevent the fixing ring 30 from loosening. The positioning rod and the elastic member (such as the torsion spring 55) in the positioning assembly 50 ensure that the protective sleeve 40 and the connecting ring 10 maintain a stable coaxial relationship. At the same time, the convex block 32 on the fixing ring 30 facilitates the grasping and installation of external tools or devices, and the overall structural design enhances the fastening property, external force resistance and installation convenience of the cable 200 joint.

[0039] In a second aspect, an embodiment of the present application discloses an automatic installation device for a cable 200 joint, which is used to install the cable joint fastening structure described above.

[0040] Referring to Figure 7 , an automatic installation device for a cable 200 joint includes an installation table 60, a clamping block 70, a driving member 80, a transmission assembly 90 and a guiding seat 100. The clamping block 70 is installed on the installation table 60. The driving member 80 is used to drive a plurality of clamping blocks 70 to approach or separate from each other, and the transmission assembly 90 is used to drive a plurality of clamping blocks 70 to rotate synchronously. The driving member 80 includes a plurality of servo electric cylinders, and the output shafts of the servo electric cylinders are fixedly connected to the clamping blocks 70. The servo electric cylinders provide precise position control and clamping force control, ensuring the stability and accuracy during the cooperation installation process of the clamping block 70 and the convex block 32.

[0041] Referring to Figure 7 and Figure 8, the transmission assembly 90 includes a driving gear 91 and a transmission gear 92 that mesh with each other, and a power source 93 that drives the driving gear 91 to rotate. The transmission gear 92 is provided with an installation groove 94, and a plurality of servo cylinders are circumferentially distributed along the installation groove 94. Through the meshing of the driving gear 91 and the transmission gear 92, the synchronous rotation of the plurality of clamping blocks 70 is achieved, improving the coordination and consistency during the installation process. On the installation table 60, there is a frame 61 and a plurality of limiting gears 95 installed on the frame 61 for limiting the transmission gear 92 to rotate freely. The limiting gears 95 are rotatably installed on the frame 61.

[0042] When the fixing ring 30 rotates in place, the connecting bar 20 is threadedly connected to the fixing ring 30, and the entire cable 200 connector will continuously rotate forward in a spiral. The guiding seat 100 is used to assist the protective sleeve 40 to move horizontally, enabling the fixing ring 30 and the connecting bar 20 to be threadedly connected. The guiding seat 100 is provided in two halves, and the two halves of the guiding seat 100 are spliced to form a guiding groove, and the protective sleeve 40 is slidably installed in the guiding groove. One half of the guiding seat 100 is slidably installed on the tabletop of the installation table 60, and the other half of the guiding seat 100 is connected to a pull rod 110. The pull rod 110 is horizontally slidably installed on the frame 61, and a limiting block 120 is threadedly installed on the pull rod 110. By changing the position of the limiting block 120, the height position of the other half of the guiding seat 100 is controlled. When the guiding seat 100 is spliced in half, the limiting block 120 abuts against the frame 61.

[0043] Furthermore, a guiding seat 100 provided in two halves is also equipped for the cable 200 connector, improving the smoothness of the overall horizontal movement of the cable 200 connector and ensuring the stability and accuracy of the protective sleeve 40 during the movement process.

[0044] When the cable 200 connector and the protective sleeve 40 are placed on the corresponding guiding seat 100, the guiding seat 100 is pushed, so that the convex block 32 of the fixing ring 30 extends into the installation groove 94. In order to make the convex block 32 and the clamping block 70 cooperate precisely, a positioning column 62 is installed on the frame 61. When the side of the convex block 32 facing away from the positioning ring abuts against the positioning column 62, the convex block 32 on the fixing ring 30 corresponds to the clamping block 70.

[0045] The working process of an automatic installation device for a cable 200 connector in an embodiment of the present application is as follows: The automatic installation device cooperates with the convex block 32 on the fixing ring 30 through the clamping block 70. Under the coordinated action of the driving member 80 and the transmission assembly 90, the clamping block 70 first moves precisely and then rotates synchronously. The protective sleeve 40 rotates horizontally forward in the guiding groove of the guiding seat 100, ensuring the stability and accuracy of the rotational installation process of the fixing ring 30 and the connecting bar 20. The overall device improves the installation efficiency and automation level of the cable connector fastening structure.

[0046] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
