Description

Technical Field

[0001] This utility model relates to the field of cable technology, and specifically to a cable connection device. Background Technology

[0002] Cables are essential for the transmission, distribution, and voltage conversion of electricity. Due to limitations in production and transportation, cables cannot be infinitely long. Electricians often use cable connectors to join cut cables together for use. The most common cable connector is the conductive tube (also known as a lug, which has a certain degree of deformability). However, existing technologies have the following problems:

[0003] Existing cable connection devices lack specialized fixing components, making maintenance or cable replacement extremely difficult due to the lack of standardized fixing and disassembly methods. Improper handling, such as forced disassembly, can further damage the cable or connection device, increasing labor costs and equipment damage risks. Furthermore, the lack of well-designed cable fixing components makes it difficult to effectively secure cables of different outer diameters. In addition, existing devices lack elastic buffer components, allowing the impact generated during cable insertion and removal to be transmitted directly to conductive components without obstruction. This makes critical conductive parts such as conductive terminals and wires highly susceptible to damage due to the inability to withstand the instantaneous impact. The absence of elastic buffer components to resist external vibrations means that even slight vibrations can cause loosening or displacement of the connection between the cable and conductive terminals, resulting in poor contact. Utility Model Content

[0004] This invention provides a cable connection device to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A cable connection device includes a connecting pipe, with cable fixing assemblies fixedly connected to both the front and rear sides of the connecting pipe, an insulating ring fixedly connected to the middle position inside the connecting pipe, a conductive terminal fixedly connected inside the insulating ring, and elastic buffer assemblies provided on both the front and rear sides of the conductive terminal.

[0007] A further improvement of this utility model is that: the cable fixing assembly includes a chuck housing one, a chuck housing two is fixedly connected to the side of the chuck housing one near the conductive terminal by bolts, the side of the chuck housing two near the conductive terminal is fixedly connected to a connecting pipe, a cable insertion hole two is opened in the middle of the chuck housing two, a circular groove two is opened inside the chuck housing two, a cable insertion hole one is opened in the middle of the chuck housing one, three annularly arrayed grooves are opened on the side of the chuck housing one away from the chuck housing two, a clamping block is slidably connected inside each of the three grooves, an engagement plate is fixedly connected to the side of each of the three clamping blocks near the chuck housing two, and a rectangular groove communicating with the inside of the chuck housing one is opened on the side of each of the three grooves near the chuck housing two.

[0008] A further improvement of this utility model is that: a circular groove is provided inside the chuck housing, a large bevel gear is rotatably connected inside the circular groove, a cable socket is provided in the middle of the large bevel gear, a planar thread is fixedly connected to the side of the large bevel gear near the groove, the three meshing plates pass through the rectangular groove and extend into the interior of the chuck housing and mesh with the planar thread on the side near the large bevel gear, three small bevel gears arranged in a ring array are meshed on the side of the large bevel gear away from the planar thread, the three small bevel gears are located inside the circular groove and their ends are rotatably connected to the inner wall of the chuck housing, and the end of the upper small bevel gear away from the cable socket extends into the outer wall of the chuck housing and is fixedly connected to a knob.

[0009] A further improvement of the present invention is that the elastic buffer assembly includes four hollow cylinders, which are rectangular and fixedly connected to the conductive terminal. The inner walls of the four hollow cylinders are slidably connected to telescopic conductive columns. The ends of the four telescopic conductive columns away from the conductive terminal are fixedly connected to conductive sheets. The outer walls of the conductive sheets are fixedly connected to pistons that are slidably connected to the inside of the conductive terminal.

[0010] A further improvement of this utility model is that: the ends of the four telescopic conductive pillars away from the conductive sheet are all fixedly connected to springs located inside the hollow cylinder, and the ends of the four springs away from the telescopic conductive pillars are fixedly connected to conductive terminals.

[0011] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0012] 1. This utility model provides a cable connection device, which achieves stable fixing of the cable through the set cable fixing components, preventing the cable from loosening or shifting during use, ensuring the stability of the cable connection, allowing operators to easily complete the installation and disassembly of the cable, and can adapt to cables of different outer diameter specifications within a certain range, improving the flexibility and applicability of the device.

[0013] 2. This utility model provides a cable connection device. Through the setting of the elastic buffer component, it can absorb and buffer the instantaneous impact force generated by external impact or cable insertion and removal operation by its own elastic deformation. It avoids the impact force acting directly on precision conductive components such as conductive terminals, and prevents them from deforming or loosening due to excessive force. This effectively reduces the probability of failures such as poor contact and wire breakage caused by insertion and removal impact, while ensuring that the cable and conductive terminals always maintain a tight and stable contact state.

[0021] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0022] like Figure 1 , Figure 2 As shown, this utility model provides a cable connection device, including a connecting pipe 10, with cable fixing components 2 fixedly connected to both the front and rear sides of the connecting pipe 10, an insulating ring fixedly connected to the middle position inside the connecting pipe 10, a conductive terminal 11 fixedly connected inside the insulating ring, and elastic buffer components 3 provided on both the front and rear sides of the conductive terminal 11.

[0023] The connecting tube 10 serves as the basic structure of the entire device. It is hollow and tubular in shape. The material can be a metal with certain strength and corrosion resistance, such as aluminum alloy. Cable fixing components 2 are fixedly connected to both the front and rear sides of the connecting tube 10 to clamp and fix the cables to be connected. At the same time, an insulating ring is fixedly connected to the middle of the connecting tube 10 by welding or other strong fixing methods. The ring can be made of ceramic or other materials with good insulation properties. Conductive terminals 11 are fixedly connected inside the insulating ring. The conductive terminals 11 are used to realize the conductive connection between the two cables. The material of the conductive terminals 11 is preferably copper with excellent conductivity. Furthermore, elastic buffer components 3 are provided on both the front and rear sides of the conductive terminals 11 to buffer external impacts that may occur during cable insertion or use.

[0024] like Figure 3-5 As shown, the cable fixing assembly 2 includes a chuck housing 1 20. A chuck housing 21 is fixedly connected to the side of the chuck housing 1 20 near the conductive terminal 11 by bolts. The side of the chuck housing 21 near the conductive terminal 11 is fixedly connected to the connecting pipe 10. A cable insertion hole 292 is provided in the middle of the chuck housing 21. A circular groove 294 is provided inside the chuck housing 21. A cable insertion hole 24 is provided in the middle of the chuck housing 1 20. Three annularly arranged grooves 23 are provided on the side of the chuck housing 1 20 away from the chuck housing 21. A clamping block 26 is slidably connected inside each of the three grooves 23. A meshing plate 27 is fixedly connected to the side of each of the three clamping blocks 26 near the chuck housing 21. A rectangular groove communicating with the inside of the chuck housing 1 20 is provided on the side of each of the three grooves 23 near the chuck housing 21.

[0025] like Figure 3-5As shown, the chuck housing 20 has an annular groove 29 inside, and a large bevel gear 290 is rotatably connected inside the annular groove 29. A cable socket 293 is provided in the middle of the large bevel gear 290. A flat thread 28 is fixedly connected to the side of the large bevel gear 290 near the groove 23. The three meshing plates 27 on the side near the large bevel gear 290 all pass through the rectangular groove and extend into the interior of the chuck housing 20 and mesh with the flat thread 28. Three small bevel gears 291 arranged in a ring array are meshed on the side of the large bevel gear 290 away from the flat thread 28. The three small bevel gears 291 are located inside the annular groove 294 and their ends, which are far apart from each other, are rotatably connected to the inner wall of the chuck housing 21. The end of the upper small bevel gear 291 away from the cable socket 292 passes through to the outer wall of the chuck housing 21 and is fixedly connected to a knob 22.

[0026] When it is necessary to fix two cables together, first, pass the cables to be connected through the cable socket 24 of the chuck housing 20, the cable socket 293 of the large bevel gear 290 on the chuck housing 21, and the cable socket 292 of the chuck housing 21 in sequence, so that the cables can be in a suitable position to be fixed. At this time, the cable ends extend into the connecting tube 10 and are close to the conductive terminal 11, ready for subsequent fixing operations.

[0027] Then, the operator initiates the fixing process by rotating the knob 22 on the outer wall of the chuck housing 21. The knob 22 is fixedly connected to the small bevel gear 291. When the knob 22 is rotated, it drives the small bevel gear 291 to rotate around its own axis in the annular groove 294. Since the three small bevel gears 291 are arranged in a circular array and all mesh with the large bevel gear 290, the rotation of the small bevel gears 291 will drive the large bevel gear 290 to rotate in the annular groove 29. The large bevel gear 290 is fixedly connected to a flat thread 28 on the side near the groove 23. As the large bevel gear 290 rotates, the flat thread 28 will drive the three meshing plates 2 to rotate with it. 7. During the movement, one end of the meshing plate 27 is fixed on the clamping block 26, and the clamping block 26 is slidably disposed in the groove 23 of the chuck housing 20. Driven by the planar thread 28, the three clamping blocks 26 will slide synchronously along the groove 23 toward the cable, and finally tightly clamp the cable. Through the cable fixing component 2, the cable is firmly fixed, preventing the cable from loosening or shifting during use, ensuring the stability of the cable connection. Operators can easily complete the installation and disassembly of the cable, and it can adapt to cables of different outer diameters within a certain range, improving the flexibility and applicability of the device.

[0028] like Figure 6As shown, the elastic buffer assembly 3 includes four hollow cylinders 30. The four hollow cylinders 30 are rectangular and fixedly connected to the conductive terminal 11. The inner walls of the four hollow cylinders 30 are slidably connected to telescopic conductive columns 32. The ends of the four telescopic conductive columns 32 away from the conductive terminal 11 are fixedly connected to conductive sheets 33. The outer walls of the conductive sheets 33 are fixedly connected to pistons 34 that are slidably connected to the inside of the conductive terminal 11.

[0029] like Figure 6 As shown, each of the four telescopic conductive posts 32 has a spring 31 fixedly connected to the end of the four springs 32 away from the conductive sheet 33. The ends of the four springs 31 away from the telescopic conductive posts 32 are fixedly connected to the conductive terminals 11.

[0030] When the cable is subjected to external impact after connection, or when the cable is inserted into the connecting tube 10, the external force is transmitted to the conductive plate 33, causing the conductive plate 33 to drive the telescopic conductive post 32 to slide towards the conductive terminal 11 within the hollow cylinder 30. At this time, the spring 31 connected to the telescopic conductive post 32 is compressed. The spring 31 absorbs and buffers this external force through its own elastic deformation, preventing the external force from directly acting on the conductive terminal 11 and the connection between the cable and the conductive terminal 11, preventing loosening of the connection and damage to conductive components due to excessive external force. When the external force disappears, under the elastic restoring force of the spring 31, the telescopic conductive post 32 will drive the conductive plate 33 and other components to return to their initial position, continuing to maintain good conductivity and connection, ensuring that the entire cable connection device can work stably and continuously. When two cables are fixed through the front and rear sides respectively... After component 2 is fixed, the conductive core of the cable will come into contact with the conductive terminal 11. Current can be conducted from the conductive core of one cable through the conductive terminal 11 to the conductive core of the other cable, thereby realizing the conductive connection between the two cables and ensuring that power and other signals can be transmitted smoothly between the cables. The insulating ring plays a role in isolating current and preventing leakage, ensuring safety and normal conductivity. The elastic buffer component 3 can absorb and buffer the instantaneous impact force generated by external impact or cable insertion and removal operations through its own elastic deformation, avoiding the impact force from acting directly on precision conductive components such as conductive terminals, preventing deformation or loosening due to excessive force, thereby effectively reducing the probability of poor contact, wire breakage and other faults caused by insertion and removal impact, while ensuring that the cable and conductive terminal always maintain a tight and stable contact state.

[0031] The working principle of this cable connection device will be explained in detail below.

[0032] like Figure 1-6As shown, when it is necessary to fix two cables together, firstly, the cables to be connected are passed sequentially through the cable socket 24 of the chuck housing 20, the cable socket 293 of the large bevel gear 290 on the chuck housing 21, and the cable socket 292 of the chuck housing 21, so that the cables can be in a suitable position to be fixed. At this time, the cable ends extend into the connecting tube 10 and are close to the conductive terminal 11, ready for subsequent fixing operations.

[0033] Then, the operator initiates the fixing process by rotating the knob 22 on the outer wall of the chuck housing 21. The knob 22 is fixedly connected to the small bevel gear 291. When the knob 22 is rotated, it drives the small bevel gear 291 to rotate around its own axis in the annular groove 294. Since the three small bevel gears 291 are arranged in a circular array and all mesh with the large bevel gear 290, the rotation of the small bevel gears 291 will drive the large bevel gear 290 to rotate in the annular groove 29. The large bevel gear 290 is fixedly connected to a flat thread 28 on the side near the groove 23. As the large bevel gear 290 rotates, the flat thread 28 will drive the three meshing plates 2 to rotate with it. 7. During the movement, one end of the meshing plate 27 is fixed on the clamping block 26, and the clamping block 26 is slidably disposed in the groove 23 of the chuck housing 20. Driven by the planar thread 28, the three clamping blocks 26 will slide synchronously along the groove 23 toward the cable, and finally tightly clamp the cable. Through the cable fixing component 2, the cable is firmly fixed, preventing the cable from loosening or shifting during use, ensuring the stability of the cable connection. Operators can easily complete the installation and disassembly of the cable, and it can adapt to cables of different outer diameters within a certain range, improving the flexibility and applicability of the device.

[0034] When the cable is subjected to external impact after connection, or when the cable is inserted into the connecting tube 10, the external force is transmitted to the conductive plate 33, causing the conductive plate 33 to drive the telescopic conductive post 32 to slide towards the conductive terminal 11 within the hollow cylinder 30. At this time, the spring 31 connected to the telescopic conductive post 32 is compressed. The spring 31 absorbs and buffers this external force through its own elastic deformation, preventing the external force from directly acting on the conductive terminal 11 and the connection between the cable and the conductive terminal 11, preventing loosening of the connection and damage to conductive components due to excessive external force. When the external force disappears, under the elastic restoring force of the spring 31, the telescopic conductive post 32 will drive the conductive plate 33 and other components to return to their initial position, continuing to maintain good conductivity and connection, ensuring that the entire cable connection device can work stably and continuously. When two cables are fixed through the front and rear sides respectively... After component 2 is fixed, the conductive core of the cable will come into contact with the conductive terminal 11. Current can be conducted from the conductive core of one cable through the conductive terminal 11 to the conductive core of the other cable, thereby realizing the conductive connection between the two cables and ensuring that power and other signals can be transmitted smoothly between the cables. The insulating ring plays a role in isolating current and preventing leakage, ensuring safety and normal conductivity. The elastic buffer component 3 can absorb and buffer the instantaneous impact force generated by external impact or cable insertion and removal operations through its own elastic deformation, avoiding the impact force from acting directly on precision conductive components such as conductive terminals, preventing deformation or loosening due to excessive force, thereby effectively reducing the probability of poor contact, wire breakage and other faults caused by insertion and removal impact, while ensuring that the cable and conductive terminal always maintain a tight and stable contact state.

[0035] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
