Description

Technical Field

[0001] The present invention relates to a wiring device, and more particularly to a power wiring device. Background Art

[0002] When power is transmitted, wires are usually used as a means of transmission. However, the power grid is often accompanied by long-distance (thousands of kilometers) power transmission, and the wires cannot reach the corresponding length. Therefore, in order to achieve long-distance transportation, short wires need to be connected with wiring devices to enable the power transmission function to operate. However, the existing wiring devices have low wiring efficiency, inconvenient operation, and safety performance needs to be improved.

[0003] For example: Chinese patent announcement number CN116979280A, announcement date October 31, 2023, the invention name is a wiring device for a target grid of a distribution network. The application discloses an electric power wiring device, including a wiring platform, a sliding member and an elastic member. When in use, the sliding rod can move in the sliding groove. When the cable needs to be clamped, the sliding rod is pushed in the direction away from the side panel to expand the clamping area, so that the cable can be clamped. The movable sliding rod can be adapted to cables of various specifications. Through the action of the elastic member, the sliding rod has a tendency to move toward the side panel, so that the sliding rod can clamp the cable. However, the wiring efficiency of this scheme is low, and the wiring operation is inconvenient. Summary of the invention

[0004] The present invention overcomes the problems of low wiring efficiency and inconvenient wiring operation of the existing power wiring device, and provides a power wiring device. In order to solve the above technical problems, the present invention adopts the following technical solutions: an electric power wiring device, comprising a base and a wire clamp structure, at least two groups of the wire clamp structures are arranged at both ends of the base, a transmission assembly is arranged inside the base, the transmission assembly includes a transmission part, the wire clamp structure includes a rotating drum, the outside of the rotating drum is connected to the transmission part by transmission, and a clamping claw assembly is arranged inside the rotating drum to move radially with the rotation of the rotating drum. In this solution, multiple wire clamp structures are arranged in the electric power wiring device, so that the operation of wiring multiple groups of wires at the same time can be realized, greatly improving the wiring efficiency; wherein, when the transmission part moves, it can drive the rotating drum to rotate, and through the rotation of the rotating drum, the clamping claw assembly inside the rotating drum will clamp or open, thereby realizing the operation of clamping and releasing the wire by the clamping claw, and realizing fast and efficient wiring operation.

[0005] Preferably, the transmission part is a double-sided rack, and the outer part of the drum is provided with meshing teeth meshing with the transmission part. The transmission part adopts a double-sided rack, one of which can mesh with the meshing teeth on the outer part of the drum, thereby driving the drum to rotate, thereby realizing the operation of clamping and releasing the line.

[0006] Preferably, the clamping jaw assembly comprises a fixed cylinder, the fixed cylinder is located inside the rotating cylinder, a plurality of clamping jaws are arranged inside the fixed cylinder, and the clamping jaws are connected by radial sliding along the fixed cylinder. The fixed cylinder provides an installation position for the clamping jaw assembly and can relatively fix the clamping jaw assembly; the clamping jaws slide along the radial direction of the fixed cylinder, so that multiple clamping jaws can be simultaneously brought close to each other to achieve clamping, or multiple clamping jaws can be simultaneously separated to achieve loosening.

[0007] Preferably, the fixed cylinder and the rotating cylinder are spaced apart, a wedge block is provided on the rotating cylinder, the clamping claw comprises a clamping plate and a sliding rod, the clamping plate is located inside the fixed cylinder, one end of the sliding rod is fixed to the clamping plate, and the other end passes through the fixed cylinder and abuts against the wedge block. The fixed cylinder and the rotating cylinder are separated from each other, the rotating cylinder needs to rotate, while the fixed cylinder is fixed, the wedge block on the rotating cylinder can rotate with the rotating cylinder, and the clamping claw is provided on the fixed cylinder, when the rotating cylinder rotates, the wedge block moves, and the wedge block squeezes the sliding rod, so that the clamping claw moves along the inner radial direction of the fixed cylinder, so that multiple clamping claws are simultaneously closed to clamp the wire.

[0008] Preferably, the transmission assembly further comprises a driving part, which is arranged on a side of the transmission part away from the wire clamp structure, and is in transmission connection with the transmission part. The driving part is used to drive the transmission part to move, and the transmission part is a double-sided rack, so that the driving part is arranged on a side away from the wire clamp structure, so that the driving part can drive the transmission part, and specifically, a gear is also arranged on the driving part to drive the rack.

[0009] Preferably, a guide groove is further provided in the base, and guide blocks are provided at both ends of the transmission part, and the guide blocks are slidably connected in the guide groove. The transmission part needs to slide inside the base to drive the drum to rotate, so guide grooves need to be provided at both ends of the transmission part to provide sufficient transmission space for the transmission part, and in order to make the transmission of the transmission part more stable, guide blocks are provided at both ends of the transmission part, and the guide blocks slide between the guide grooves.

[0010] Preferably, the driving part is also provided with a locking mechanism, which includes a pawl assembly and a ratchet wheel provided on the driving part. The locking mechanism is used to lock the driving part to ensure that the drum is in a certain position and does not change, that is, after the clamping claw clamps the wire, the clamping claw needs to maintain a clamping state. The pawl and the ratchet wheel can ensure that the driving part rotates in one direction to achieve the clamping of the clamping claw, and when the driving part stops rotating, the pawl and the ratchet wheel can also lock the driving part to prevent it from rotating, thereby achieving the clamping claw to maintain a clamping state.

[0011] Preferably, the pawl assembly includes a pawl and a connecting rod fixed to the pawl, the connecting rod is slidably connected to the base, and an elastic member is sleeved on the connecting rod. The connecting rod and the base are slidably connected, so that the pawl can be disengaged from the ratchet wheel, so that the driving part is reset, that is, the clamp releases the wire; and when the pawl is disengaged from the ratchet wheel, it needs to be reset, and the elastic member on the connecting rod can ensure that the pawl returns to the ratchet wheel.

[0012] Preferably, the rotating drum is provided with a notch, a support rod is provided in the notch, and the support rod is slidably connected to the notch. Since the rotating drum and the fixed drum are two independent drum structures, and the rotating drum is arranged outside the fixed drum, it is necessary to provide a notch structure on the surface of the rotating drum, and then support the fixed drum through the support rod; at the same time, in order to ensure that the rotating drum can rotate normally, the length of the notch needs to be longer to avoid the support rod, that is, the support rod can slide in the notch to prevent the support rod from hindering the rotation of the rotating drum.

[0013] Preferably, an offset structure is provided between the slide bar and the fixed tube, and the offset structure includes an oblique groove and a slider. The offset structure is provided between the slide bar and the fixed tube, so that when the slide bar moves radially, the slide bar will also be offset along the outer circumference of the fixed tube, that is, when the clamping jaws are clamping or loosening, the clamping jaws can also rotate along the circumference of the fixed tube; when the clamping jaws are clamping, the clamping jaws also rotate to a certain extent, thereby twisting the clamped wires circumferentially, so that the wire bundle at the wiring point explodes, which can enable operators to better select wires and facilitate operation on the one hand, and on the other hand, prevent different wires from being overlapped together during wiring, causing safety accidents.

DETAILED DESCRIPTION

[0022] The technical solution of the present invention is further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0023] Example 1: Figures 1 to 4 The power wiring device shown includes a base 1 and a wire clamp structure 2. The base 1 is a rectangular plate-shaped structure. Two mutually perpendicular slot structures are provided inside the base 1, which are defined as a first slot 25 and a second slot 26. A transmission assembly 3 is arranged inside the first slot 25 and the second slot 26. The transmission assembly 3 includes a driving part 5 and a transmission part 4, wherein the driving part 5 is arranged in the first slot 25 and the transmission part 4 is arranged in the second slot 26. The wire clamp structure 2 includes a rotating drum 6 and a fixed drum 7. A clamping claw assembly 8 is arranged inside the fixed drum 7. The outside of the rotating drum 6 and the transmission part 4 are linked. When the transmission part 4 moves, the rotating drum 6 rotates accordingly, thereby causing the clamping claw assembly 8 inside the rotating drum 6 to move, thereby achieving the clamping or release of the wire.

[0024] Specifically, Figure 2As shown, the first slot body 25 and the second slot body 26 inside the base 1 are perpendicular to each other and interconnected. The second slot body 26 is located at the upper part of the first slot body 25. The first slot body 25 is a cylindrical slot body, and the second slot body 26 is a rectangular parallelepiped slot body. A driving part 5 is arranged inside the first slot body 25. The driving part 5 is a cylindrical rotating shaft structure, and can be accommodated in the first slot body 25 and rotate relative to the first slot body 25. A transmission part 4 is arranged in the second slot body 26. The transmission part 4 is a double-sided rack structure, and the racks on the two faces of the transmission part 4 are distributed up and down. A first gear 15 is arranged on the driving part 5 and at a position corresponding to the transmission part 4. The first gear 15 can mesh with the rack under the driving part 5. When the driving part 5 rotates, the first gear 15 rotates to drive the transmission part 4 to move laterally along the second slot body 26, thereby driving the wire clamp structure 2 to operate.

[0025] Specifically, the wire clamp structure 2 includes a rotating drum 6, which is arranged on the upper part of the base 1 and corresponds to the upper part of the transmission part 4. A third slot 27 for accommodating the rotating drum 6 is provided on the base 1, and the third slot 27 is connected to the second slot 26. A part of the rotating drum 6 is located inside the third slot 27, and another part is located above the base 1. Engaging teeth 9 are provided on the outer wall of the rotating drum 6, and the engaging teeth 9 can mesh with the rack on the transmission part 4, so that when the transmission part 4 moves laterally along the inside of the second slot 26, the transmission part 4 drives the rotating drum 6 to rotate, thereby driving the wire clamp structure 2 to operate.

[0026] A fixed cylinder 7 is arranged inside the rotating cylinder 6. The fixed cylinder 7 is fixed relative to the base 1 and the rotating cylinder 6. The fixed cylinder 7 is concentrically arranged with the rotating cylinder 6, and the rotating cylinder 6 and the fixed cylinder 7 are spaced apart, that is, a gap is arranged between the rotating cylinder 6 and the fixed cylinder 7, and a wedge block 11 and a clamping claw 10 are arranged at the gap position between the fixed cylinder 7 and the rotating cylinder 6. Specifically, a wedge block 11 structure is arranged on the side of the rotating cylinder 6 close to the fixed cylinder 7. There are three groups of wedge blocks 11 in total. The three groups of wedge blocks 11 are evenly distributed on the inner wall of the rotating cylinder 6, and the wedge directions of the three groups of wedge blocks 11 are consistent, that is, the size of the wedge blocks 11 changes from large to small along the clockwise direction or the counterclockwise direction; and a clamping claw 10 is arranged on the fixed cylinder 7 and at the position corresponding to each wedge block 11. The clamping claw 10 includes a sliding rod 13 and a clamping plate 12. The sliding rod 13 radially penetrates The slide rod 13 passes through the inner wall of the fixed cylinder 7, one end of the slide rod 13 is located in the gap between the rotating cylinder 6 and the fixed cylinder 7, and abuts against the wedge block 11, and the other end of the slide rod 13 is located inside the fixed cylinder 7. The slide rod 13 can produce a radial sliding effect relative to the fixed cylinder 7, so that when the rotating cylinder 6 rotates, due to the action of the wedge block 11, the wedge block 11 will push the slide rod 13 toward the axial position of the rotating cylinder 6, so that the three groups of jaws 10 will come together at the same time to clamp the wire harness in the middle.

[0027] The drum 6 is also provided with two slots 21, which are symmetrically distributed on the drum 6. The drum 6 is evenly divided into three parts on the cross section where the slots 21 are located, and three groups of wedge blocks 11 are arranged on the three-part structure of the drum 6. The middle part of the drum 6 is provided with meshing teeth 9 on the outer wall of the drum 6 for meshing with the transmission part 4, while the two side parts of the drum 6 are not provided with meshing teeth 9.

[0028] A support rod 22 is provided inside the notch 21. There are two support rods 22, which are symmetrically arranged on both sides of the rotating drum 6. Specifically, the support rod 22 is arranged obliquely on the base 1. One end of the support rod 22 is fixedly connected to the base 1, and the other end of the support rod 22 passes through the notch 21 on the rotating drum 6 and is fixedly connected to the outer wall of the fixed drum 7, so that the fixed drum 7 can be fixed. It should be noted that the notch 21 is a long groove structure opened along the circumference of the rotating drum. Therefore, the notch 21 can avoid the support rod 22, so that the rotating drum 6 can keep rotating normally. At the same time, through the reasonable design of the length of the notch 21, the support rod 22 can play a limiting role on the rotating drum 6, preventing the rotating drum 6 from rotating too much and clamping the wires too tightly. The reasonable design of the length of the notch 21 can also ensure that the structure of the clamping claw assembly 8 can clamp different numbers of wire bundles.

[0029] It should also be noted that in this solution, the clamping plate 12 is an arc-shaped plate structure. After the clamping plates 12 in the three groups of clamping jaws 10 are close to each other, they can form a circle, so that the wire bundle can be clamped. In order to ensure that the clamping plate 12 does not damage the wires, a rubber pad 28 is also provided on the surface of the clamping plate 12. When the clamping plate 12 clamps the wires, the rubber pad 28 can better clamp the wires and increase the contact area between the rubber pad 28 and the wires, so that the clamping plate 12 clamps the wires more firmly.

[0030] It should also be noted that an opening structure is provided above the fixed cylinder 7 for inserting or removing the wires. Similarly, an opening is also provided on the rotating cylinder 6. The positions of the opening of the rotating cylinder 6 and the opening of the fixed cylinder 7 correspond to each other in the initial state. After the rotating cylinder 6 rotates a certain amount, the opening of the rotating cylinder 6 and the opening of the fixed cylinder 7 are still close to each other. It should also be noted that a reset member (not shown in the figure) is also provided on the slide bar 13 for the reset operation of the slide bar 13.

[0031] A guide groove 14 is further provided inside the base 1 and at both ends of the second groove body 26, and a guide block 16 is provided at both ends of the transmission part 4. The guide block 16 is fixed as one body with the transmission part 4, and the size of the guide block 16 matches the size of the guide groove 14, and the guide block 16 is slidably connected with the guide groove 14. The guide groove 14 provides sufficient transmission space for the transmission part 4, and makes the transmission of the transmission part 4 more stable.

[0032] like Figure 4 As shown, a locking mechanism is also provided inside the driving portion 5 and the base 1, and the locking mechanism includes a pawl assembly and a ratchet 18 on the driving portion 5. The ratchet 18 is provided at a position close to the end of the driving portion 5, and the pawl assembly is also provided at a position close to the side of the base 1. The pawl assembly includes a pawl 17, a connecting rod 19 and an elastic member 20. An accommodating cavity 29 is provided in the base 1 and corresponds to the position where the ratchet 18 is located. The accommodating cavity 29 is communicated with the second slot body 26, and one end of the connecting rod 19 is fixedly connected to the pawl 17, and the other end passes through the side wall of the base 1 and extends to the outside of the base 1. The connecting rod 19 is slidably connected to the side wall of the base 1, and the pawl 17 is located in the accommodating cavity 29 and slides. At the same time, the pawl 17 is also transmission-connected to the ratchet 18. When the driving portion 5 rotates in one direction (such as Figure 2 As shown in the figure, it rotates in the clockwise direction), the pawl 17 will not hinder the rotation of the ratchet 18, and when the driving part 5 rotates in the opposite direction, the pawl 17 will limit the rotation of the ratchet 18, thereby ensuring that the transmission part 4 moves in one direction, that is, the rotating drum 6 can only rotate in one direction, so that the clamping jaws 10 can clamp and maintain the clamping state.

[0033] An elastic member 20 is also provided on the connecting rod 19. The elastic member 20 is a spring. The spring is sleeved on the outside of the connecting rod 19. A button 30 is provided on one end of the connecting rod 19 and located outside the base 1. By pressing the button 30, the pawl 17 will disengage from the ratchet 18, so that the restriction of the ratchet 18 is eliminated, so that the driving part 5 can rotate in the reverse direction, that is, the transmission part 5 is transmitted in the reverse direction, and then the clamping jaw 10 is released. It should also be noted that in order to make the driving part 5 rotate better, one end of the driving part 5 extends out of the base 1, and a screw cap 31 is provided on the driving part 5. The screw cap 31 and the locking mechanism are provided on the same side of the base 1 to facilitate the operation of the locking mechanism and the driving part 5.

[0034] In this embodiment, there are three groups of wire clamp structures 2, each group has two wire clamp structures 2, and each group of wire clamp structures 2 is arranged on both sides of the base 1, for clamping two bundles of wires that need to be wired. Similarly, the transmission assembly 3 is arranged corresponding to the wire clamp structures 2 on both sides, so that the wire clamp structures 2 on both sides can rotate simultaneously. In this solution, different groups of wire clamp structures 2 can be set according to the actual number of wires connected, which greatly improves the wiring efficiency.

[0035] The specific process is as follows: first, rotate the screw cap 31 clockwise (such as Figure 2As shown in the direction shown in the figure), the driving part 5 rotates clockwise, driving the first gear 15 on the driving part 5 to rotate clockwise, the first gear 15 drives the transmission part 4 to move leftward, and the transmission part 4 drives the three groups of rotating drums 6 above to rotate counterclockwise, and the clamping claw assemblies 8 in the three rotating drums 6 perform the clamping operation at the same time. Specifically, the wedge block 11 on the rotating drum 6 drives the sliding rod to move toward the axial direction of the fixed drum 7, driving the three groups of clamping plates 12 in the fixed drum 7 to form a circular structure, thereby clamping the wire harness. When the wiring is completed, the clamping jaws 10 need to release the wire harness. Specifically, the button 30 at the end of the connecting rod 19 on the pawl assembly is pressed to disengage the pawl 17 from the ratchet 18 on the driving portion 5. After the driving portion 5 is free from the restriction of the pawl 17, the screw cap 31 can be rotated in the reverse direction, and the driving portion 5 rotates in the reverse direction, and finally the rotating drum 6 rotates in the reverse direction, and the squeezing effect of the wedge block 11 on the sliding rod 13 is eliminated. The sliding rod 13 is reset under the action of the reset member, driving the clamping plate 12 to reset, and finally the connected wires can be separated from the inside of the fixed cylinder 7, completing the wiring operation.

[0036] Example 2: Figures 1 to 6 The power wiring device shown includes a base 1 and a wire clamp structure 2. The base 1 is a rectangular plate-shaped structure. Two mutually perpendicular slot structures are provided inside the base 1, which are defined as a first slot 25 and a second slot 26. A transmission assembly 3 is arranged inside the first slot 25 and the second slot 26. The transmission assembly 3 includes a driving part 5 and a transmission part 4, wherein the driving part 5 is arranged in the first slot 25 and the transmission part 4 is arranged in the second slot 26. The wire clamp structure 2 includes a rotating drum 6 and a fixed drum 7. A clamping claw assembly 8 is arranged inside the fixed drum 7. The outside of the rotating drum 6 and the transmission part 4 are linked. When the transmission part 4 moves, the rotating drum 6 rotates accordingly, thereby causing the clamping claw assembly 8 inside the rotating drum 6 to move, thereby achieving the clamping or release of the wire.

[0037] Specifically, Figure 2 As shown, the first slot body 25 and the second slot body 26 inside the base 1 are perpendicular to each other and interconnected. The second slot body 26 is located at the upper part of the first slot body 25. The first slot body 25 is a cylindrical slot body, and the second slot body 26 is a rectangular parallelepiped slot body. A driving part 5 is arranged inside the first slot body 25. The driving part 5 is a cylindrical rotating shaft structure, and can be accommodated in the first slot body 25 and rotate relative to the first slot body 25. A transmission part 4 is arranged in the second slot body 26. The transmission part 4 is a double-sided rack structure, and the racks on the two faces of the transmission part 4 are distributed up and down. A first gear 15 is arranged on the driving part 5 and at a position corresponding to the transmission part 4. The first gear 15 can mesh with the rack under the driving part 5. When the driving part 5 rotates, the first gear 15 rotates to drive the transmission part 4 to move laterally along the second slot body 26, thereby driving the wire clamp structure 2 to operate.

[0038] Specifically, the wire clamp structure 2 includes a rotating drum 6, which is arranged on the upper part of the base 1 and corresponds to the upper part of the transmission part 4. A third slot 27 for accommodating the rotating drum 6 is provided on the base 1, and the third slot 27 is connected to the second slot 26. A part of the rotating drum 6 is located inside the third slot 27, and another part is located above the base 1. Engaging teeth 9 are provided on the outer wall of the rotating drum 6, and the engaging teeth 9 can mesh with the rack on the transmission part 4, so that when the transmission part 4 moves laterally along the inside of the second slot 26, the transmission part 4 drives the rotating drum 6 to rotate, thereby driving the wire clamp structure 2 to operate.

[0039] A fixed cylinder 7 is arranged inside the rotating cylinder 6. The fixed cylinder 7 is fixed relative to the base 1 and the rotating cylinder 6. The fixed cylinder 7 is concentrically arranged with the rotating cylinder 6, and the rotating cylinder 6 and the fixed cylinder 7 are spaced apart, that is, a gap is arranged between the rotating cylinder 6 and the fixed cylinder 7, and a wedge block 11 and a clamping claw 10 are arranged at the gap position between the fixed cylinder 7 and the rotating cylinder 6. Specifically, a wedge block 11 structure is arranged on the side of the rotating cylinder 6 close to the fixed cylinder 7. There are three groups of wedge blocks 11 in total. The three groups of wedge blocks 11 are evenly distributed on the inner wall of the rotating cylinder 6, and the wedge directions of the three groups of wedge blocks 11 are consistent, that is, the size of the wedge blocks 11 changes from large to small along the clockwise direction or the counterclockwise direction; and a clamping claw 10 is arranged on the fixed cylinder 7 and at the position corresponding to each wedge block 11. The clamping claw 10 includes a sliding rod 13 and a clamping plate 12. The sliding rod 13 radially penetrates The slide rod 13 passes through the inner wall of the fixed cylinder 7, one end of the slide rod 13 is located in the gap between the rotating cylinder 6 and the fixed cylinder 7, and abuts against the wedge block 11, and the other end of the slide rod 13 is located inside the fixed cylinder 7. The slide rod 13 can produce a radial sliding effect relative to the fixed cylinder 7, so that when the rotating cylinder 6 rotates, due to the action of the wedge block 11, the wedge block 11 will push the slide rod 13 toward the axial position of the rotating cylinder 6, so that the three groups of jaws 10 will come together at the same time to clamp the wire harness in the middle.

[0040] like Figure 5 and Figure 6As shown, an offset structure is provided between the fixed cylinder 7 and the slide bar 13. When the slide bar 13 moves radially, the entire slide bar 13 will also deviate circumferentially along the fixed cylinder 7, so that the clamping plate 12 will deviate circumferentially inside the fixed cylinder 7. Specifically, the offset structure includes an oblique groove 23 and a slider 24. A guide hole 32 for radial movement of the slide bar 13 is provided inside the fixed cylinder 7. The oblique groove 23 is provided in the guide hole 32 in the fixed cylinder 7. The slider 24 is provided on the slide bar 13. The slider 24 on the slide bar 13 cooperates with the oblique groove 23 in the guide hole 32. Therefore, when the slide bar 13 moves radially, the entire slide bar 13 will also deviate circumferentially along the fixed cylinder 7, so that the clamping plate 12 will deviate circumferentially inside the fixed cylinder 7. That is, when the clamping jaw 10 is performing the clamping operation, the clamping jaw 10 can also rotate along the circumference of the fixed tube 7; when the clamping jaw 10 is performing the clamping operation, the clamping jaw 10 also rotates to a certain extent, thereby circumferentially twisting the clamped wires, so that the ends of the wire bundle at the wiring point are exploded (scattered). On the one hand, it allows operators to better select wires and facilitate operations. On the other hand, it can also prevent different wires from being overlapped together during wiring, causing safety accidents.

[0041] It should be noted that in order to allow the slide rod 13 to be circumferentially offset, the width of the guide hole 32 needs to be greater than the width of the slide rod 13. In order to prevent the slide rod 13 from rotating around the slider 24, the slider 24 needs to be set to a prismatic shape. Specifically, a quadrilateral slider can be used, thereby limiting the relative rotational movement between the oblique groove 23 and the slider 24.

[0042] The drum 6 is also provided with two slots 21, which are symmetrically distributed on the drum 6. The drum 6 is evenly divided into three parts on the cross section where the slots 21 are located, and three groups of wedge blocks 11 are arranged on the three-part structure of the drum 6. The middle part of the drum 6 is provided with meshing teeth 9 on the outer wall of the drum 6 for meshing with the transmission part 4, while the two side parts of the drum 6 are not provided with meshing teeth 9.

[0043] A support rod 22 is provided inside the notch 21. There are two support rods 22, which are symmetrically arranged on both sides of the rotating drum 6. Specifically, the support rod 22 is arranged obliquely on the base 1. One end of the support rod 22 is fixedly connected to the base 1, and the other end of the support rod 22 passes through the notch 21 on the rotating drum 6 and is fixedly connected to the outer wall of the fixed drum 7, so that the fixed drum 7 can be fixed. It should be noted that the notch 21 is a long groove structure opened along the circumference of the rotating drum. Therefore, the notch 21 can avoid the support rod 22, so that the rotating drum 6 can keep rotating normally. At the same time, through the reasonable design of the length of the notch 21, the support rod 22 can play a limiting role on the rotating drum 6, preventing the rotating drum 6 from rotating too much and clamping the wires too tightly. The reasonable design of the length of the notch 21 can also ensure that the structure of the clamping claw assembly 8 can clamp different numbers of wire bundles.

[0044] It should also be noted that in this solution, the clamping plate 12 is an arc-shaped plate structure. After the clamping plates 12 in the three groups of clamping jaws 10 are close to each other, they can form a circle, so that the wire bundle can be clamped. In order to ensure that the clamping plate 12 does not damage the wires, a rubber pad 28 is also provided on the surface of the clamping plate 12. When the clamping plate 12 clamps the wires, the rubber pad 28 can better clamp the wires and increase the contact area between the rubber pad 28 and the wires, so that the clamping plate 12 clamps the wires more firmly.

[0045] It should also be noted that an opening structure is provided above the fixed cylinder 7 for inserting or removing the wires. Similarly, an opening is also provided on the rotating cylinder 6. The positions of the opening of the rotating cylinder 6 and the opening of the fixed cylinder 7 correspond to each other in the initial state. After the rotating cylinder 6 rotates a certain amount, the opening of the rotating cylinder 6 and the opening of the fixed cylinder 7 are still close to each other. It should also be noted that a reset member (not shown in the figure) is also provided on the slide bar 13 for the reset operation of the slide bar 13.

[0046] A guide groove 14 is further provided inside the base 1 and at both ends of the second groove body 26, and a guide block 16 is provided at both ends of the transmission part 4. The guide block 16 is fixed as one body with the transmission part 4, and the size of the guide block 16 matches the size of the guide groove 14, and the guide block 16 is slidably connected with the guide groove 14. The guide groove 14 provides sufficient transmission space for the transmission part 4, and makes the transmission of the transmission part 4 more stable.

[0047] like Figure 4As shown, a locking mechanism is also provided inside the driving portion 5 and the base 1, and the locking mechanism includes a pawl assembly and a ratchet 18 on the driving portion 5. The ratchet 18 is provided at a position close to the end of the driving portion 5, and the pawl assembly is also provided at a position close to the side of the base 1. The pawl assembly includes a pawl 17, a connecting rod 19 and an elastic member 20. An accommodating cavity 29 is provided in the base 1 and corresponds to the position where the ratchet 18 is located. The accommodating cavity 29 is communicated with the second slot body 26, and one end of the connecting rod 19 is fixedly connected to the pawl 17, and the other end passes through the side wall of the base 1 and extends to the outside of the base 1. The connecting rod 19 is slidably connected to the side wall of the base 1, and the pawl 17 is located in the accommodating cavity 29 and slides. At the same time, the pawl 17 is also transmission-connected to the ratchet 18. When the driving portion 5 rotates in one direction (such as Figure 2 As shown in the figure, it rotates in the clockwise direction), the pawl 17 will not hinder the rotation of the ratchet 18, and when the driving part 5 rotates in the opposite direction, the pawl 17 will limit the rotation of the ratchet 18, thereby ensuring that the transmission part 4 moves in one direction, that is, the rotating drum 6 can only rotate in one direction, so that the clamping jaws 10 can clamp and maintain the clamping state.

[0048] An elastic member 20 is also provided on the connecting rod 19. The elastic member 20 is a spring. The spring is sleeved on the outside of the connecting rod 19. A button 30 is provided on one end of the connecting rod 19 and located outside the base 1. By pressing the button 30, the pawl 17 will disengage from the ratchet 18, so that the restriction of the ratchet 18 is eliminated, so that the driving part 5 can rotate in the reverse direction, that is, the transmission part 5 is transmitted in the reverse direction, and then the clamping jaw 10 is released. It should also be noted that in order to make the driving part 5 rotate better, one end of the driving part 5 extends out of the base 1, and a screw cap 31 is provided on the driving part 5. The screw cap 31 and the locking mechanism are provided on the same side of the base 1 to facilitate the operation of the locking mechanism and the driving part 5.

[0049] In this embodiment, there are three groups of wire clamp structures 2, each group has two wire clamp structures 2, and each group of wire clamp structures 2 is arranged on both sides of the base 1, for clamping two bundles of wires that need to be wired. Similarly, the transmission assembly 3 is arranged corresponding to the wire clamp structures 2 on both sides, so that the wire clamp structures 2 on both sides can rotate simultaneously. In this solution, different groups of wire clamp structures 2 can be set according to the actual number of wires connected, which greatly improves the wiring efficiency.

[0050] The specific process is as follows: first, rotate the screw cap 31 clockwise (such as Figure 2As shown in the orientation, the driving part 5 rotates clockwise, driving the first gear 15 on the driving part 5 to rotate clockwise, and the first gear 15 drives the transmission part 4 to move leftward, and the transmission part 4 drives the three groups of rotating drums 6 above to rotate counterclockwise, and the clamping jaws 8 in the three rotating drums 6 perform clamping operations at the same time. Specifically, the wedge block 11 on the rotating drum 6 drives the slide bar to move toward the axial direction of the fixed drum 7. At the same time, under the action of the offset structure, the clamping jaws 10 also deflect along the circumference of the fixed drum 7, and drive the three groups of clamping plates 12 in the fixed drum 7 to form a circular structure. When the supporting plate 12 just starts to contact the wire harness, the wire harness is initially limited. As the clamping jaws 10 continue to move radially, the supporting plate 12 gradually clamps and tightens the wire harness, thereby causing the ends of the wire harness at the wiring location to explode (scatter). When the wiring is completed, the clamping jaws 10 need to release the wire harness. Specifically, the button 30 at the end of the connecting rod 19 on the pawl assembly is pressed to disengage the pawl 17 from the ratchet 18 on the driving portion 5. After the driving portion 5 is free from the restriction of the pawl 17, the screw cap 31 can be rotated in the reverse direction, and the driving portion 5 rotates in the reverse direction, and finally the rotating drum 6 rotates in the reverse direction, and the squeezing effect of the wedge block 11 on the sliding rod 13 is eliminated. The sliding rod 13 is reset under the action of the reset member, driving the clamping plate 12 to reset, and finally the connected wires can be separated from the inside of the fixed cylinder 7, completing the wiring operation.
