Description

Technical Field

[0001] The invention relates to the technical field of cable joint tools, and in particular to a cable joint fastening device. Background Art

[0002] Cable joints are also called cable heads. After the cable is laid, in order to make it a continuous line, each section of the line must be connected as a whole, and these connection points are called cable joints. The cable joints in the middle of the cable line are called intermediate joints, and the cable joints at both ends of the line are called terminal heads. Cable joints are used to lock and fix the incoming and outgoing lines, and play a role in waterproofing, dustproofing and vibration prevention. The main function of cable joints is to make the line unobstructed, keep the cable sealed, and ensure the insulation level at the cable joints, so that it can operate safely and reliably. If the seal is poor, not only will oil leakage cause the oil-impregnated paper to dry up, but moisture will also invade the inside of the cable, causing its insulation performance to deteriorate.

[0003] Some electrical installation workers often do not pay attention to the installation quality when laying wires: they do not install insulating sleeves where they should be; they do not install junction boxes where they should be; they even do not use the twisting method at the wire joints, but use the illegal hook-shaped connection method; this hook-shaped connection method has a large contact resistance, and it will continue to generate heat when powered on, causing the nearby wooden boards to gradually dry and carbonize, and finally burn, causing a fire; the heating of wire joints will not only cause a large amount of power loss, but also seriously affect the normal operation of electrical equipment. At the least, the working current in the line will increase and the life of the electrical equipment will be shortened. At the worst, it will suddenly interrupt the ongoing production, scientific research, medical surgery and other activities, and will also cause fires and electric shock accidents, etc., causing inestimable losses;

[0004] Therefore, it is necessary to invent a cable joint fastening device, which is not only convenient for manual operation, but also comes with an insulating sleeve, which is convenient for manual installation and can avoid manual forgetting to use the insulating sleeve. At the same time, by mechanized cable connection and tightening the cable joints, the problem of looseness at the cable joints is reduced and accidents are avoided. Summary of the invention

The cylindrical gear III 224 is fixedly connected, and the cylindrical gear III 224 is rotatably mounted on the U-shaped bracket I 223; the shafts of the cylindrical gear III 224 and the cylindrical gear IV 225 are fixedly connected, and the cylindrical gear IV 225 is rotatably mounted on the U-shaped bracket II 226; the U-shaped bracket II 226 and the spur rack II 227 are fixedly connected, and the spur rack II 227 is slidably mounted on the fixed frame II 209; the spur rack II 227 and the cylindrical gear V 228 are meshed with each other, and the cylindrical gear V 228 is rotatably mounted on the fixed frame II 209. Specifically, the servo motor III 220 drives the cylindrical gear V 228 to rotate. The cylindrical gear II 221 rotates, which in turn drives the cylindrical gear V 228 to rotate, thereby driving the spur rack II 227 and the spur rack I 222 to descend, further driving the U-shaped bracket I 223, the cylindrical gear III 224, the U-shaped bracket II 226 and the cylindrical gear IV 225 to descend, so that the cylindrical gear III 224 and the rotating gear II 109 are meshed, and the cylindrical gear IV 225 and the rotating gear I 107 are meshed, and the cylindrical gear III 224 is driven to rotate by the motor on the side of the U-shaped bracket I 223, thereby driving the cylindrical gear IV 225 to rotate. Thereby, the rotating gear Ⅰ107 and the rotating gear Ⅱ109 are driven to rotate, and further driven to rotate and move outward at the same time. Since there are gaps between the multiple inclined panels Ⅰ106 and the multiple inclined panels Ⅱ108, when the rotating gear Ⅰ107 and the rotating gear Ⅱ109 move toward the outside, they will squeeze the inclined panels Ⅰ106 and the rotating gear Ⅰ107, so that the gaps between the multiple inclined panels Ⅰ106 and the multiple inclined panels Ⅱ108 become smaller, thereby squeezing the wires.

[0069] Working principle:

[0070] The support part 1 is manually placed on the ground, and a single conductor is manually passed through a hole of the fixed disc 103, and the spring of the squeezing mechanism 104 pushes the arc plate of the squeezing mechanism 104 to squeeze the conductor, thereby limiting the conductor;

[0071] The rod at the lower end of the small arc plate 202 is manually inserted into the slide groove of the square bottom plate 101, and then the sliding annular plate 206, the fixed annular plate 207 and the fixed rod 208 are manually pulled to move, so that the fixed rod 208 is inserted into the hole of the fixed disc 103; and then the mechanical fastening part 2 is installed on the supporting part 1;

[0072] Two conductors are respectively inserted into one end of the inclined plate Ⅰ106 and one end of the inclined plate Ⅱ108, and the cam 214 is driven to rotate by the servo motor Ⅱ215, so that the cam 214 pushes the screw moving mechanism 218 to descend. After the slider of the screw moving mechanism 218 descends to both sides of the conductor, the motor of the screw moving mechanism 218 drives the screw of the screw moving mechanism 218 to rotate, and then drives the slider of the screw moving mechanism 218 to clamp a conductor, and then drives the square block 211 to rise by the extension of the servo electric cylinder 210, and then drives the connecting rod 212 to drive the support frame 213 to slide to the middle position, and then drives the cam 214, the servo motor Ⅱ215, the connecting plate 216, the small spring 217, the screw moving mechanism 218 and the conductor to move to the middle position, so that the two conductors are connected together;

[0073] The cylindrical gear II 221 is driven to rotate by the servo motor III 220, and then the cylindrical gear V 228 is driven to rotate, thereby driving the spur rack II 227 and the spur rack I 222 to descend, and further driving the U-shaped bracket I 223, the cylindrical gear III 224, the U-shaped bracket II 226 and the cylindrical gear IV 225 to descend, so that the cylindrical gear III 224 and the rotating gear II 109 are meshed, and the cylindrical gear IV 225 and the rotating gear I 107 are meshed, and the cylindrical gear III 224 is driven to rotate by the motor on the side of the U-shaped bracket I 223, thereby driving the cylindrical gear IV 225 rotates, thereby driving the rotating gear Ⅰ107 and the rotating gear Ⅱ109 to rotate, and further driving the rotating gear Ⅰ107 and the rotating gear Ⅱ109 to rotate while moving outward. Since there are gaps between the multiple inclined plates Ⅰ106 and the multiple inclined plates Ⅱ108, when the rotating gear Ⅰ107 and the rotating gear Ⅱ109 move toward the outside, they will squeeze the inclined plates Ⅰ106 and the rotating gear Ⅰ107, so that the gaps between the multiple inclined plates Ⅰ106 and the multiple inclined plates Ⅱ108 become smaller, thereby squeezing the wires;

[0074] The cylindrical gear I 203 is driven to rotate by the servo motor I 201, which in turn drives the arc-shaped internal gear 204 to move, thereby driving the pushing and clamping structure, the fixed frame II 209, the servo electric cylinder 210, the square block 211, the connecting rod 212, and the connecting block 219 to rotate a certain angle, so that the pushing and clamping structure, the fixed frame II 209, the servo electric cylinder 210, the square block 211, the connecting rod 212, and the connecting block 219 are directed toward the top of the other two conductors, and the above operation is repeated to connect and fix the other two conductors together, and so on, until all the conductors are connected, and then the mechanical fastening part 2 is removed as a whole to facilitate the next connection of the conductor.
