Description

Technical Field

[0001] This invention relates to the field of cable wiring, and more particularly to an outdoor cable wiring device and wiring method for electrical engineering. Background Technology

[0002] A cable is made of one or more insulated conductors and an outer insulating protective layer. It is a wire that transmits electricity or information from one place to another. During use, because cables have a large output current, when connected to small power supply locations, the cable needs to be disconnected and the external cable connected to the cable conductor to achieve the transmission of a suitable amount of power.

[0003] Existing technology discloses some invention patents related to cable connection devices. Chinese patent application number 202010619333.8 discloses a cable connector, including a connector sleeve and a connector body. Both ends of the connector sleeve are connected to terminals. A second fixed end is connected to the center of the top of the connector sleeve. Both ends of the top of the connector sleeve are connected to a first fixed end. A limiting end is provided at the center of the bottom of the connector sleeve. The connector body is fixed inside the connector sleeve inside the limiting end.

[0004] Existing wiring methods typically use copper conduit crimping, which requires crossing the wires in the cable, cutting them to allow insertion and alignment into the copper conduit. However, the current cutting method involves workers measuring the dimensions and then cutting with wire cutters. Due to the potential for errors in cutting different wires, the wires end up being of different lengths inside the copper conduit, causing bulges when they are wrapped together. This can lead to overheating and burning of the cable insulation when carrying high currents. Therefore, this invention proposes an outdoor cable wiring device and method for electrical engineering to solve the above problems. Summary of the Invention

[0016] A wiring method for an outdoor cable connection device in electrical engineering, the wiring method comprising the following steps:

[0017] Step 1, Initial clamping: Place the two cables to be connected into the two first clamping mechanisms respectively to fix and clamp the cables;

[0018] Step 2, Straightening and Cutting: Place the three wires in the cable into the straightening clamping mechanism, straighten the wires using the straightening clamping mechanism, and then start the cutting mechanism to cut the straightened wires;

[0019] Step 3, Copper tube crimping: After the wire is cut, the drive motor is started to drive the first bidirectional threaded rod to rotate, thereby driving the two vertical plates to move towards each other, thereby driving the two first clamping mechanisms to move towards each other, and connecting the cut wire to the crimping mechanism for crimping.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The first clamping mechanism drives the cable to move, thereby connecting the cut conductors to the crimping mechanism for crimping, completing the cable connection. By automatically straightening and cutting each conductor after the cable is fixed, and adjusting the cutting position of the conductors, it is beneficial to ensure that the conductors are of the same length after being crimped together. This helps to reduce the occurrence of bulges after the cable is connected, thus facilitating the normal use of the cable.

[0022] 2. The user starts the third motor, which drives the second bidirectional threaded rod to rotate. The second bidirectional threaded rod drives the two support rods to move towards each other, thereby driving the two tool mounting brackets to move towards each other. This causes the two first cutting blades to cut the straightened wires. At the same time, the two second cutting blades can cut the insulation layer on the wires. Then, when the extension end of the second cylinder retracts and drives the mounting block to move, the second cutting blades can peel off the cut insulation layer, exposing the copper wires for splicing, which facilitates the splicing of the two wires.

[0023] 3. The copper tube is limited at both ends by the limiting plate, which helps to prevent the copper tube from moving when the wire is inserted into the copper tube. When the third cylinder moves the pressure plate downward to press the copper tube, the L-shaped rod first contacts the limiting plate. The L-shaped rod pushes the limiting plate downward to separate the limiting plate from the copper tube, which helps to prevent the limiting plate from blocking the deformation of the copper tube.

[0042] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0043] like Figures 2 to 17 An outdoor cable connection device for electrical engineering is shown, including a base 1. Two vertical plates 2 are symmetrically fixed on the top of the base 1. A drive motor 3 is fixed on the side of one vertical plate 2 away from the other vertical plate 2. The output shaft of the drive motor 3 passes through the adjacent vertical plate 2 and is fixed with a first bidirectional threaded rod 4. The end of the first bidirectional threaded rod 4 facing away from the drive motor 3 is rotatably connected to the other vertical plate 2. The outer rings of the two ends of the first bidirectional threaded rod 4 are symmetrically threaded with sliders 5. Both sliders 5 are slidably connected to the base 1.

[0044] Both sliders 5 have a first clamping mechanism fixed to their tops. The first clamping mechanism is used to fix and clamp the cable. A straightening and clamping mechanism is installed on the opposite sides of both sliders 5. The straightening and clamping mechanism is used to straighten and clamp the exposed wires after the cable insulation layer is stripped. Two cutting mechanisms are symmetrically fixed to the top of the base 1. The cutting mechanism is located between the two straightening and clamping mechanisms. After the straightening and clamping mechanisms straighten and clamp the wires and adjust them to the required position, the cutting mechanism is used to cut the straightened and clamped wires. A crimping mechanism is installed on the top of the base 1. The crimping mechanism is located between the two cutting mechanisms. The crimping mechanism is used to crimp the two wires after they have been cut and adjusted for connection. During operation, errors can easily occur when cutting different wires, resulting in uneven wire lengths after connection inside the copper tube. When wrapped together, bulges can easily form, causing overheating and burning of the cable insulation layer when a large current is passed through. This embodiment of the present invention can solve the above problems. The specific implementation method is as follows: The operator strips the insulation layer of the cable to be connected... The cable is then placed on the first clamping mechanism and clamped securely. The three conductors of the cable are then placed in the straightening clamping mechanism, which straightens them sequentially. The cutting mechanism then cuts the straightened conductors, completing the shearing of the three conductors. Straightening the conductors before cutting ensures that the cut conductors are of equal length. The symmetrically arranged straightening clamping mechanism and cutting mechanism at both ends can simultaneously process the two cables to be connected. The operator then starts the drive motor 3, which rotates the first bidirectional threaded rod 4, causing the two vertical plates 2 to move towards each other. This, in turn, causes the two first clamping mechanisms to move towards each other. The first clamping mechanisms move the cable, connecting the cut conductors to the crimping mechanism for crimping, thus completing the cable connection. By automatically straightening and cutting each conductor after the cable is fixed, and adjusting the cutting position, the lengths of the conductors are made equal after crimping, reducing the likelihood of bulging after cable connection and promoting normal cable use.

[0045] In one embodiment of the present invention, the first clamping mechanism includes a support block 6, which is fixed to the top of the slider 5. A circular groove is provided on the top of the support block 6, and a first cylinder 7 is fixed inside the circular groove. After the telescopic end of the first cylinder 7 extends out of the circular groove, a pressure block 8 is fixed thereon. Both the bottom of the pressure block 8 and the top of the support block 6 are provided with arc-shaped grooves 9, and the two arc-shaped grooves 9 can be combined to form a circular hole. During operation, the operator places the cable in the arc-shaped groove 9 on the top of the support block 6, and starts the first cylinder 7 to drive the pressure block 8 to move downward and press the cable. The arc-shaped groove 9 helps to reduce the damage to the cable caused by compression, thereby facilitating the normal use of the cable after connection.

[0046] In one embodiment of the present invention, the straightening and clamping mechanism includes a slide groove 10 and a first motor 11. The slide groove 10 is formed on the side of the slider 5 facing the pressing mechanism. The first motor 11 is fixed to the rear side of the slider 5. The output shaft of the first motor 11 passes through the side wall of the slider 5 and extends into the interior of the slide groove 10, where a threaded rod 12 is fixed. The front end of the threaded rod 12 is rotatably connected to the side wall of the slide groove 10. The outer ring of the threaded rod 12 is fixed to a second cylinder 13 through a movable seat threadedly connected to it. The second cylinder 13 is slidably connected to the slide groove 10. A mounting block 14 is fixed to the telescopic end of the second cylinder 13. The top of the mounting block 14 has six grooves 15, arranged in pairs. Each pair of grooves 15 is slidably connected to a clamping component. The mounting block 14 has an internal cavity and three openings on its top, located directly below the three clamping components and connected to the cavity. During operation, the user initially clamps the three wires of the cable through the three clamping components, applying some friction but not fully clamping them. Then, the second cylinder 13 is activated, extending its telescopic end to move the mounting block 14. Mounting block 14 moves three clamping components. During this movement, the clamping components grip the wire, causing one end of the wire held by the clamping components to move with the clamping components, while the other end of the wire is clamped and fixed inside the cable, thus straightening the wire. When the middle clamping component touches the cutting mechanism, the second cylinder 13 stops. Then, the clamping components fix and tighten the wire. After the cutting component starts and cuts the wire, the extension end of the second cylinder 13 retracts, causing mounting block 14 to move and reset. Then, the first motor 11 drives the threaded rod 12 to rotate. The first motor 11 drives the second cylinder 13 to move along the slide groove 10, thereby causing the second cylinder 13 to move the mounting block 14 to move the side wires to the middle. Then, the second cylinder 13 is activated, and the extension end of the second cylinder 13 extends to move the mounting block 14. Then, the above steps are repeated to cut the wires on both sides. The first motor 11 drives the threaded rod 12 to rotate, which in turn drives the second cylinder 13 to move and adjust the wires to the initial position, so that the three wires are cut to the same length. This helps to reduce the situation where the wires are of different lengths after the cable is connected, thus facilitating the normal use of the cable.

[0047] In one embodiment of the present invention, the clamping assembly includes a second motor 16 and a support frame 17. The second motor 16 is fixed to the side of the mounting block 14 near the second cylinder 13. The two sides of the bottom of the support frame 17 are slidably connected to the interiors of two grooves 15 in the same group. The output shaft of the second motor 16 passes through the side wall of the mounting block 14 and extends into the cavity where a round rod 18 is fixed. A sliding rod 19 is slidably inserted into the interior of the round rod 18. A first gear 20 is fixed to the end of the sliding rod 19 away from the round rod 18. The top of the support frame 17... The symmetrical sliding connection consists of two clamping plates 21, each with an inclined plate 22 fixed to its bottom. A through groove 23 is formed on the left side of each inclined plate 22, and a sliding rod 24 is slidably connected inside each through groove 23. A connecting block 25 is fixed to both ends of each sliding rod 24. A first rack 26 is fixed to the bottom of the connecting block 25, meshing with a first gear 20. A limiting block 27 is slidably connected to the right side of the first rack 26, with the end of the limiting block 27 away from the first rack 26 connected to the first gear 20. Rotary connection; During operation, the user starts the second motor 16, which drives the round rod 18 to rotate, and the round rod 18 drives the sliding rod 19 to rotate, thereby driving the first gear 20 to rotate. Through the meshing of the first gear 20 and the first rack 26, the first gear 20 drives the first rack 26 to move vertically downward. The first rack 26 drives the connecting block 25 to move downward, thereby driving the two sliding rods 24 to move vertically downward with the connecting block 25. During the downward movement of the two sliding rods 24, the inclined through groove 23 guides the two inclined plates 22 to move towards each other, thereby driving the two clamping plates 21 to move towards each other to clamp the wire. The user first clamps the wire initially, so that there is a certain friction between the wire and the clamping plate 21, but the wire can still slide with the clamping plate 21. Therefore, when the second cylinder 13 drives the clamping assembly to move, the wire can be straightened, which is beneficial to obtaining wires of the same length when cutting the wire, thus ensuring that the wires are of the same length after splicing, which is beneficial to the normal use of the cable.

[0048] In one embodiment of the present invention, a first spring 28 is fixed inside each of the six grooves 15. The ends of the six first springs 28 near the support frame 17 are respectively fixedly connected to the adjacent support frame 17. A slot is formed inside each of the six clamping plates 21, and a rotating roller 55 is rotatably connected inside each of the six slots. Curved grooves are formed on opposite sides of the two clamping plates 21 above the same support frame 17. The middle portions of the six rotating rollers 55 penetrate the sidewalls of the corresponding curved grooves and extend into the interior of the curved grooves. A second gear 56 is fixed to the bottom end of each of the six rotating rollers 55, and the edges of the six second gears 56 penetrate the sidewalls of the clamping plates 21 and extend outwards. The second cylinder 13 housing is fixed with a connecting frame 57 near the mounting block 14. Six second racks 58 are fixed to the top of the connecting frame 57, and six second gears 56 are respectively matched with the six second racks 58. During operation, because the clamping assembly tightly holds the wire during wire cutting, the wire may break when the middle wire is moved to the side. This embodiment of the invention solves the above problem. Specifically, by using the provided first spring 28, when the middle wire is moved to the side, the taut wire pulls the clamping assembly to compress the first spring 28, thereby preventing the wire from being pulled during machine operation. To prevent breakage and unnecessary losses, during wire connection, the second cylinder 13 is appropriately contracted, and the right sides of the three clamping components are aligned in the same vertical plane under the force of the first spring 28, thus facilitating simultaneous connection of the three wires. During connection, the force of the first spring 28 ensures a neater connection of the wires inside the copper tube. Through the rotating roller 55 inside the clamping plate 21, when the clamping plate 21 moves under the push of the second cylinder 13 to straighten the wires, the second gear 56 meshes with the second rack 58. During the movement of the clamping plate 21, the second rack 58 drives the second gear 56 to rotate, and the rotation of the second gear 56 enables… The rotating roller 55 is driven to rotate in the direction of the clamping plate 21, thereby giving the wire a traction force. As the clamping plate 21 pulls the end of the wire to straighten it, if the bending length of the wire at the initial clamping position is greater than the distance the clamping plate 21 moves the wire, then during the movement of the wire by the clamping plate 21, the rotating roller 55 applies a traction force to the surface of the wire through rotation, so that the wire is continuously pulled forward during the movement. This increases the pulling length of the wire when moving the same distance, which helps to improve the straightening effect of the wire.

[0049] In one embodiment of the present invention, the cutting mechanism includes a support column 29, which is fixed to the top of the base 1. A first slot is formed on the front side of the support column 29. A third motor 30 is fixed to the top of the support column 29. The output shaft of the third motor 30 passes through the side wall of the support column 29 and extends into the first slot, where a second bidirectional threaded rod 31 is fixed. Two support rods 32 are symmetrically threaded at both ends of the second bidirectional threaded rod 31. A tool mounting bracket 33 is fixed to the end of each support rod 32 away from the support column 29. The two tool mounting brackets 33 are symmetrically arranged. A first cutting blade 34 is installed on the right side inside each of the two tool mounting brackets 33. Each mounting bracket 33 has a second cutting blade 35 installed in the center. During operation, the user starts the third motor 30, which drives the second bidirectional threaded rod 31 to rotate. The second bidirectional threaded rod 31 drives the two support rods 32 to move towards each other, thereby driving the two tool mounting brackets 33 to move towards each other. This causes the two first cutting blades 34 to cut the straightened wires. At the same time, the two second cutting blades 35 can cut the insulation layer on the wires. Then, when the extension end of the second cylinder 13 retracts and drives the mounting block 14 to move, the second cutting blades 35 can peel off the cut insulation layer, exposing the copper wires for splicing, which facilitates the splicing of the two wires.

[0050] In one embodiment of the present invention, the crimping mechanism includes an L-shaped bracket 36 and two support legs 37. The L-shaped bracket 36 is fixed to the top of the base 1. A third cylinder 38 is fixed to the bottom of the crossbar portion of the L-shaped bracket 36. A connecting plate 39 is fixed to the bottom of the telescopic end of the third cylinder 38. Two pressure plates 40 are symmetrically fixed to the bottom of the connecting plate 39. Both support legs 37 are fixed to the top of the base 1. A support plate 41 is fixed to the top of each support leg 37. The ends of the two support plates 41 away from the support legs 37 are connected to the L-shaped bracket 36. The front side of the bracket 36 is fixedly connected. Three arc-shaped grooves 42 are provided on the top of the two support plates 41 and the bottom of the two pressure plates 40. The two pressure plates 40 are located directly above the two support plates 41. Three rotating mechanisms are installed between the two pressure plates 40. During the downward movement of the pressure plates 40 to squeeze the copper tube, the rotating mechanisms drive the copper tube to rotate. Three limiting mechanisms are installed on the opposite sides of the two pressure plates 40 to limit the ends of the copper tube. During operation, the worker places the copper tube... Inside the arc-shaped groove 42 at the top of the support plate 41, a limiting mechanism limits both ends of the copper tube, preventing the copper tube from moving when two wires are inserted. After the two wires are inserted, the third cylinder 38 is activated, which moves the connecting plate 39 downward. The connecting plate 39 moves the pressure plate 40 downward, and the pressure plate 40 and the support plate 41 work together to press the copper tube, causing it to deform and fix the inserted wires. This crimps the two wires together. During the crimping process, a rotating mechanism allows the copper tube to rotate. If the end of the wire is stuck at the edge of the copper tube and cannot be inserted further, rotating the copper tube allows the guide to rotate, which helps the wire to detach from the edge of the copper tube and resume insertion. This ensures that the two wires make full contact inside the copper tube, reducing uneven wire lengths after splicing due to misalignment.

[0051] In one embodiment of the present invention, the rotating mechanism includes a fixed rod 43 and a fixed plate 44. Both the fixed plate 44 and the fixed rod 43 are fixed to one side of a support plate 41 facing the other support plate 41. A telescopic rod 45 is fixed to the side of the fixed plate 44 facing the fixed rod 43. A pin 46 is fixed to the telescopic end of the telescopic rod 45. A ring 47 is slidably connected to the telescopic end of the fixed rod 43. A second spring 48 is sleeved on the outer periphery of the telescopic rod 45. One end of the second spring 48 is fixedly connected to the fixed plate 44, and the other end is fixedly connected to the ring 47. A sliding plate 49 is rotatably sleeved on the outer ring of the fixed rod 43. A clearance groove 50 is formed on the side of the sliding plate 49 facing the fixed plate 44. The pin 46 is slidably connected to the clearance groove 50. During operation, the third cylinder 38 drives the connecting plate 39 to move downwards, thereby driving the pressure plate. When the 40 moves downward to press the copper tube, it can drive the fixing rod 43 and the fixing plate 44 to move downward. The fixing rod 43 drives the sliding plate 49 to move downward. When the sliding plate 49 moves downward and contacts the copper tube, the second spring 48 causes the sliding plate 49 to push the copper tube as it continues to move downward. At the same time, the sliding plate 49 will be subjected to the reaction force of the copper tube, so that the bottom of the sliding plate 49 will be in contact with the surface of the copper tube as it continues to move downward. When the sliding plate 49 moves downward against the copper tube, it is subjected to the elastic force of the second spring 48, so the sliding plate 49 will squeeze the copper tube. In turn, the sliding plate 49 can drive the copper tube to rotate as it moves downward. This is beneficial for the copper tube to rotate so that the wire can make full contact when it cannot make full contact with the inner wall of the copper tube.

[0052] In one embodiment of the present invention, the limiting mechanism includes two L-shaped rods 51 and two second slots 52. The two L-shaped rods 51 are fixed on the side wall of the pressure plate 40, and the two second slots 52 are opened on the side wall of the support plate 41. A third spring 53 is fixed inside each of the two second slots 52. A limiting plate 54 is fixed to the top of the two third springs 53. The limiting plate 54 is slidably connected to the second slots 52. During operation, when the user places the copper tube inside the arc-shaped groove 42 at the top of the support plate 41, the limiting plate 54 limits both ends of the copper tube, thereby preventing the copper tube from moving when the wire is inserted into it. When the third cylinder 38 moves the pressure plate 40 downward to press the copper tube, the L-shaped rods 51 first contact the limiting plate 54. The L-shaped rods 51 push the limiting plate 54 downward to separate the limiting plate 54 from the copper tube, thereby preventing the limiting plate 54 from blocking the deformation of the copper tube.

[0053] like Figure 1 The diagram illustrates a wiring method for an outdoor cable connection device in electrical engineering, comprising the following steps:

[0054] Step 1, Initial clamping: Place the two cables to be connected into the two first clamping mechanisms respectively to fix and clamp the cables;

[0055] Step 2, Straightening and Cutting: Place the three wires in the cable into the straightening clamping mechanism, straighten the wires using the straightening clamping mechanism, and then start the cutting mechanism to cut the straightened wires;

[0056] Step 3, copper tube crimping: After the wire is cut, the drive motor 3 is started to drive the first bidirectional threaded rod 4 to rotate, thereby driving the two vertical plates 2 to move towards each other, thereby driving the two first clamping mechanisms to move towards each other, and connecting the cut wire to the crimping mechanism for crimping.

[0057] Working principle of this invention:

[0058] Because errors can easily occur during the cutting of different wires, the wires may be of varying lengths after being joined inside the copper conduit. This can lead to bulges when the conduit is wrapped together, causing overheating and potentially burning out the cable insulation when carrying high current. This embodiment of the invention solves these problems. The specific implementation is as follows: The operator peels back the insulation of the cable to be joined, then places the cable on a first clamping mechanism for secure clamping. Next, the three wires in the cable are placed in a straightening clamping mechanism, which sequentially straightens the three wires. Then, the cutting mechanism is activated to cut the straightened wires, thus completing the shearing of the three wires. Straightening the wires before cutting ensures that the cut wires... With the same wire length, the straightening and clamping mechanism and the cutting mechanism, symmetrically arranged at both ends, can simultaneously process the two cables to be connected. Then, the operator starts the drive motor 3 to drive the first bidirectional threaded rod 4 to rotate, thereby driving the two vertical plates 2 to move towards each other, thereby driving the two first clamping mechanisms to move towards each other. The first clamping mechanism drives the cable to move, thereby connecting the cut wires to the crimping mechanism for crimping, completing the cable connection. By automatically straightening and cutting each wire after the cable is fixed, and adjusting the wire cutting position, it is beneficial to ensure that the wires are the same length after being crimped together, thereby reducing the occurrence of bulges after cable splicing, which is beneficial to the normal use of the cable.
