[0002] In power systems, high and low voltage distribution cabinets serve as core equipment for power distribution and control. The quality of the crimping of their internal wiring terminals is directly related to the safe and stable operation of the entire power system. Before crimping, the insulation layer of the internal connecting wires must be stripped off with wire strippers. The terminal is then inserted into the exposed copper end of the wire and crimped using a crimping device.

[0031] The following is combined with Figures 1-9 This application is described in further detail.

[0032] The present application discloses a novel electrical contact made of precious metal materials, and an embodiment discloses a crimping device for high and low voltage distribution cabinet terminal blocks.

[0033] Reference Figure 1 、 Figure 2 A crimping device for terminal blocks of a high and low voltage distribution cabinet includes a crimping device body 1.

It can be carried to the high and low voltage distribution cabinet to crimp and strip the connecting wires.

[0035] Reference Figure 3 、 Figure 4The stripping assembly 2 includes a fixed cylinder 21 fixedly connected to the inner wall of the crimping device body 1, the outer wall of the fixed cylinder 21 is fixed to the inner wall of the crimping device body 1, the inner wall of one end of the fixed cylinder 21 located in the crimping device body 1 is slidably connected to the outer wall of the rotating cylinder 22, the inner walls of the fixed cylinder 21 and the rotating cylinder 22 are slidably connected to the outer wall of the working cylinder 23, the inner wall of the fixed cylinder 21 and the inner wall of the rotating cylinder 22 form the same plane, the outer wall of the working cylinder 23 is in contact with the inner wall of the fixed cylinder 21 and the rotating cylinder 22, so that the working cylinder 23 is unobstructed when moving inside the fixed cylinder 21 and the rotating cylinder 22, and a first sliding groove is provided on the inner wall of the end of the fixed cylinder 21 away from the rotating cylinder 22 26. The first slide groove 26 is spiral, and the end of the first slide groove 26 away from the rotating cylinder 22 is semicircular. The spiral shape and the semicircular shape of the first slide groove 26 are connected end to end. The inner wall of the first slide groove 26 is slidably connected to the outer wall of the first cylinder 24. The end of the first cylinder 24 away from the first slide groove 26 is fixed to the outer surface of the working cylinder 23. The inner wall of the rotating cylinder 22 is provided with a second slide groove 27, and the second slide groove 27 runs through the interior of the rotating cylinder 22. The second slide groove 27 is vertical, and the inner wall of the second slide groove 27 is slidably connected to the outer wall of the second cylinder 25 without a gap. The end of the second cylinder 25 located outside the second slide groove 27 is fixed to the outer surface of the working cylinder 23.

[0036] During use, the rotating cylinder 22 is driven by the motor 6. When the rotating cylinder 22 rotates, the second cylinder 25 located inside the second slide groove 27 drives the working cylinder 23 to rotate. The rotation of the working cylinder 23 drives the first cylinder 24 to slide in the semicircular ring of the first slide groove 26. The semicircular ring is used to drive the working cylinder 23 to rotate half a circle, so that the blade 48 cuts the connecting wire one circle. When the first cylinder 24 slides in the spiral shape of the first slide groove 26, the spiral shape is used to drive the working cylinder 23 to rotate and move. The rotation of the working cylinder 23 drives the second cylinder 25 to slide inside the second slide groove 27, thereby realizing the stripping of the insulation layer at one end of the connecting wire through the crimping assembly 3 and the cutting assembly 4.

[0037] Reference Figure 5 、 Figure 6The crimping assembly 3 includes a fixing plate 31 fixedly connected to the inner wall of the working cylinder 23, and the end of the fixing plate 31 away from the rotating cylinder 22 is outwardly expanded. The inner walls of the outwardly expanded ends of the fixing plate 31 are symmetrically slidably connected to the outer walls of the two sliding rods 32. The end of the sliding rod 32 that slides inside the fixing plate 31 is inclined, and the inclination of the sliding rod 32 is perpendicular to the outwardly expanded end of the fixing plate 31. In this way, the two sliding rods 32 will move and clamp each other while sliding inside the fixing plate 31. One side of the surface of the two sliding rods 32 is respectively connected to the two pressing rods 31. The surface of the joint 35 is fixed, and the pressing joint 35 is arranged at the end of the sliding rod 32 away from the fixed plate 31. The upper and lower surfaces of the two sliding rods 32 are respectively provided with grooves 36. The surfaces of the two grooves 36 are hinged to one end of a connecting rod 33.

A cleaning groove 37 is provided on the surface of one end of the working cylinder 23 located outside the fixed cylinder 21, and the cleaning groove 37 extends to the interior of the working cylinder 23.

[0038] When the crimping device body 1 is used in the cutting and stripping mode, the cylinder 7 drives the round shaft 34 to move, and the movement of the round shaft 34 drives the connecting rod 33 to deflect and move. When the connecting rod 33 moves, it drives the two sliding bars 32 to slide inside the fixed plate 31, and the sliding bars 32 move closer to each other. The sliding bars 32 drive the crimping heads 35 to move closer to each other. When the crimping heads 35 touch the insulation layer of the connecting wire, the cylinder 7 stops moving, and the crimping heads 35 clamp the end of the connecting wire located inside the working cylinder 23. When the crimping device body 1 is used in the crimping mode, the crimping heads 35 continue to move when they touch the terminal of the connecting wire. When the crimping heads 35 move, they will push the terminal to abut against the connecting wire, ensuring that the contact area between the terminal and the copper core meets the current carrying capacity requirement. When the crimping heads 35 continue to move, they continue to approach each other to deform the terminal and crimp it with the copper core. The cleaning groove 37 is used to take out the peeled off insulation layer, and the part of the working cylinder 23 with the cleaning groove 37 can be disassembled to facilitate cleaning the inside of the working cylinder 23.

[0039] Reference Figure 6 、 Figure 7The cutting assembly 4 includes an opening plate 47 fixedly connected to the inner wall of the working cylinder 23. A placement port is opened in the middle of the opening plate 47 for inserting the connecting line from the placement port. The placement port corresponds to the clamping center of the crimping head 35. The inner walls of the placement port of the opening plate 47 on both sides are connected to the top of the opening plate 47. The opening plate 47 is connected to the interior of the square groove 41. The inner walls at both ends of the opening plate 47 slide with the outer surfaces of the two clamping plates 46. The size of the clamping plates 46 is adapted to the size of the inner wall of the opening plate 47. The surfaces of the two clamping plates 46 and the two blades 48 close to the clamping plates 46 and are not sharp. They are symmetrical and detachable, which is convenient for replacing blades of different sizes. 48, used to adapt to the insulation layer of different depths, the two blades 48 are arranged on the side where the two plywoods 46 are close to each other, a square groove 41 is provided on the top of the inner wall of the working cylinder 23, the bottom of the square groove 41 is connected to the inside of the working cylinder 23, the inner wall of the square groove 41 is slidably connected to the two sides of the slide 43, the surface of the slide 43 and the surface of the circular shaft 34 are connected by a push rod 42, the surface of the slide 43 is symmetrically provided with inclined grooves 44, the two inclined grooves 44 are inclined, the inner walls of the two inclined grooves 44 are respectively slidably connected to the outer walls of one end of the two auxiliary rods 45, and the ends of the two auxiliary rods 45 away from the inclined grooves 44 are respectively fixed to the tops of the two plywoods 46.

[0040] When the crimping device body 1 is used in the cutting and stripping mode, the cylinder 7 drives the circular shaft 34 to move, and the push rod 42 is driven to move. The movement of the push rod 42 drives the slide plate 43 to slide inside the square groove 41. When the slide plate 43 slides, it drives the two auxiliary rods 45 to move closer to each other through the oblique groove 44. When the two auxiliary rods 45 move, they drive the clamping plate 46 to slide inside the opening plate 47. When the two clamping plates 46 move, they drive the blade 48 to move toward the connecting wire. The blade 48 is inserted into the insulation layer of the connecting wire, and the blade 48 is driven to rotate by the stripping component 2 to cut the insulation layer of the connecting wire. When the crimping device body 1 is used in the crimping mode, the clamping plate 46 drives the clamping plate 52 to move to fix the insulation layer of the connecting wire in contact with the terminal, and reversely fixes the insulation layer end during the crimping process to eliminate the bending of the connecting wire caused by the crimping reaction force, thereby further improving the alignment stability.

[0041] Reference Figure 8 、 Figure 9The auxiliary component 5 includes a third slide groove 51 opened inside the clamping plate 46, the inner wall of the third slide groove 51 is slidably connected to the outer surface of the clamping plate 52, the third slide groove 51 passes through the end of the clamping plate 46 close to the connecting line, the third slide groove 51 and the clamping plate 52 are both C-shaped, the clamping plate 52 is located inside the clamping plate 46 at one end and is slidably connected to the irregular rod 55, the irregular rod 55 passes through the interior of the opening plate 47, and a cylindrical groove 56 is provided on the side of the clamping plate 52 close to the outside of the working cylinder 23. The inner wall of the cylindrical groove 56 slides with the outer wall of the irregular rod 55 at one end of the clamping plate 52, and the end of the irregular rod 55 located inside the cylindrical groove 56 is fixed to one end of the spring 57, and the other end of the spring 57 is fixed to the inner wall of the cylindrical groove 56. The opening plate 47 is far away A long groove 53 is provided on one side away from the working cylinder 23, and the inner wall of the long groove 53 slides with the outer wall of the irregular rod 55. An irregular groove 54 is provided on the side of the splint 46 close to the long groove 53, and the inner wall of the irregular groove 54 slides with the outer wall of the irregular rod 55. The size of the irregular rod 55 at one end of the cylindrical groove 56 is larger than the size at the end inside the long groove 53. The long groove 53 and the irregular groove 54 are on the same horizontal line. The sizes at both ends of the irregular groove 54 are different from the size in the middle. The size of the irregular rod 55 inside the splint 46 is adapted to the sizes at both ends of the irregular groove 54 and the cylindrical groove 56. The size of the irregular rod 55 inside the opening plate 47 is adapted to the sizes in the middle of the long groove 53 and the irregular groove 54. In this way, the position of the clamping plate 52 can be limited.

[0042] When it is necessary to switch the mode, the operator presses the irregular rod 55, and the part of the irregular rod 55 located inside the long groove 53 enters the irregular groove 54. Since the dimensions of the two ends of the irregular groove 54 are larger than the end of the irregular rod 55 away from the spring 57, the middle of the irregular groove 54 is adapted to the end of the irregular rod 55 away from the spring 57. The operator moves the irregular rod 55 to move to the other end of the irregular groove 54, and the irregular rod 55 drives the clamping plate 52 to move. The end of the clamping plate 52 located outside the third slide groove 51 exceeds the length of the blade 48. The operator stops pressing the irregular rod 55, and the elastic force of the spring 57 pushes the end of the irregular rod 55 located inside the clamping plate 46 into the irregular groove 54 away from the end of the spring 57. The irregular groove 54 clamps the spring 57 to prevent movement, thereby realizing the function of switching the crimping device body 1 to perform terminal crimping. To switch again, just press the irregular rod 55 again to drive the clamping plate 52 to retract, thereby changing the use function of the crimping device body 1.

[0043] Reference Figure 2 、 Figure 5A space is reserved between the stripping component 2 and the interior of the crimping device body 1 for installing the motor 6. The fixed end of the motor 6 is fixed to the inner wall of the crimping device body 1. The output end of the motor 6 is fixed to one end of the rotating cylinder 22 located inside the crimping device body 1. The inner side of the fixed plate 31 is fixed to the mounting end of the cylinder 7. The output end of the cylinder 7 passes through the fixed plate 31, and the output end of the cylinder 7 is fixed to the middle surface of the circular shaft 34. The photoelectric sensor is installed above the inner wall of the working cylinder 23. The photoelectric sensor adopts the OMRON E3Z series.

[0044] Among them, the cylinder 7 and the motor 6 belong to the existing technology, and their structural principles will not be repeated. The cylinder 7 adopts the AirTac SC32-200 model, and the motor 6 adopts the Panasonic MINAS A6 series 400W servo motor 6. The circuit connection and startup process of the device are as follows: the main power supply is converted into 24V DC and 48V DC through the switching power supply, and supplied to the PLC, sensor, solenoid valve and servo motor 6 respectively; the PLC serves as the core controller, and sets parameters and monitors the status through the touch screen. The touch screen is arranged on the outside of the crimping device body 1. After receiving the connection line in place signal detected by the photoelectric sensor, the solenoid valve is triggered to drive the cylinder 7 to fix the connection line and start the motor 6, driving the stripping component 2 to complete the cutting and stripping of the insulation layer; in the crimping mode, the cylinder 7 pushes the crimping component 3 to move, and dynamically adjusts the air pressure through the proportional valve to ensure that the crimping force is accurate and stable.

[0045] The control flow is as follows: Signal acquisition: photoelectric sensor → PLC; Peeling process: PLC opens the solenoid valve first, the push rod 42 moves into position → the connection line is in position and the sensor confirms → the motor 6 is started, the spiral peeling is completed → the peeling completion sensor confirms; Switching mode: prompt the operator to press the irregular rod 55; PLC reads the position signal → enters the crimping process; Crimping process: PLC opens the solenoid valve, cylinder 7 moves → completed.

[0046] The implementation principle of a terminal crimping device for a high and low voltage distribution cabinet in an embodiment of the present application is as follows: when crimping precious metal terminals (gold-plated terminals, silver-plated terminals, etc.), the crimping device body 1 is in a wire cutting and stripping mode in the initial state, and the connecting wire is passed through the opening of the opening plate 47 and inserted into the interior of the working cylinder 23. After the photoelectric sensor detects a signal that the connecting wire is in place, the solenoid valve is triggered to drive the cylinder 7. The cylinder 7 extends and drives the circular shaft 34 to move. The circular shaft 34 moves through the connecting rod 33 and the sliding rod 32 to move the crimping head 35 to fix the stripped end of the insulation layer of the connecting wire. During this process, the circular shaft 34 moves and drives the push rod 42 to move at the same time. The push rod 42 moves through the slide plate 43 and the inclined groove 44 to enable the auxiliary rod 45 to drive the two clamps 46 to clamp each other, and the clamp 46 drives the blade 48 to move and insert into the insulation layer of the connecting wire.

[0047] Then the operator starts the motor 6 through the touch screen, and the motor 6 drives the rotating cylinder 22 to rotate. The rotating cylinder 22 drives the working cylinder 23 to rotate through the second cylinder 25 and the second slide 27. The working cylinder 23 slides inside the first slide 26 through the first cylinder 24 to rotate the working cylinder 23 half a circle. The working cylinder 23 drives the blade 48 to rotate around the connecting line to completely cut the insulation layer. The working cylinder 23 is rotated and moved through the first slide 26 to peel off the cut insulation layer. The fixing of the crimping head 35 and the rotating cutting of the blade 48 avoid To prevent the connecting wire from having an uneven cut, the connecting wire at the stripping end of the connecting wire is fixed to the blade 48 in the insulation layer cut through the crimping head 35. The stripping component 2 drives the crimping head 35 and the blade 48 in the working cylinder 23 to move and strip the insulation layer, thereby avoiding uneven insulation stripping caused by the belt and improving the stripping efficiency. The blade 48 is rotated half a circle by the use of the first cylinder 24 and the first slide groove 26 to cut and separate the insulation layer from the copper core, and then drives the insulation layer to rotate on the copper core and move to strip. The rotation of the insulation layer is used to screw the copper core together.

[0048] Then, the operator presses the irregular rod 55 to make the irregular rod 55 slide inside the irregular groove 54 and drive the clamping plate 52 to move. The length of the clamping plate 52 outside the third slide groove 51 is greater than the length of the blade 48, thereby switching the function of the crimping device to crimp the terminal of the connecting wire. The device integrates the three core functions of cutting, stripping and crimping through the use of the stripping component 2, the crimping component 3, the cutting component 4 and the auxiliary component 5. There is no need to manually transfer the workpiece or switch tools. By squeezing the irregular rod 55 and moving the clamping plate 52 to make the clamping plate 52 longer than the blade 48, the function of the crimping device body 1 is switched to perform terminal crimping. After the insulation layer is stripped, the user takes it out and puts the terminal in. Then The end of the connecting wire with the terminal is placed in the stripping component 2 and the cutting component 4, and the cylinder 7 drives the circular shaft 34 to move so that the crimping head 35 touches and clamps the connecting wire and then continues to move. During the movement and clamping process, the crimping head 35 can push the terminal to abut and crimp the copper core of the connecting wire. By using the crimping assembly 3, the stripped insulation layer of the connecting wire is fixed when the crimping device body 1 is used in the cutting and stripping mode, and the terminal of the connecting wire is pushed and crimped when the crimping device body 1 is used in the crimping mode. The terminal of the connecting wire is pushed and crimped, and one end of the sliding rod 32 is tilted and slid inside the fixed plate 31 to push the terminal to abut against the connecting wire during the clamping process of the crimping head 35. During the abutment process, the crimped terminal is clamped to fix the terminal and the copper core of the connecting wire.

[0049] During the crimping process of the crimping head 35, the clamping plate 46 drives the clamping plate 52 to move to fix the end of the insulation layer of the connecting wire, so as to prevent the connecting wire from moving and bending during the movement and abutment of the crimping assembly. By using the cutting assembly 4, the insulation layer of the connecting wire is cut when the crimping device body 1 is used in the cutting and stripping mode, and the connection between the connecting wire and the terminal is fixed when the crimping device body 1 is used in the crimping mode. When the crimping assembly 3 fixes the connecting wire, the cutting assembly 4 is synchronously driven to move, forming parallel operations in time and space, reducing equipment idling and waiting.
