[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-5 This utility model provides a technical solution:

[0020] In this technical solution, a power engineering wiring device includes a wiring base 1. An adjusting base plate a2 is mounted on the upper left side of the wiring base 1, and an adjusting base plate b5 is mounted on the upper right side of the wiring base 1. A wiring frame a3 and a wiring frame b4 are mounted on the upper ends of both the adjusting base plate a2 and the adjusting base plate b5. Clamping cavities 14 are formed on the opposite sidewalls of the wiring frames a3 and b4. Arc-shaped plates b16 are mounted on the inner sidewalls of the two clamping cavities 14. The inner and outer sides are fitted with arc-shaped plates a15; the sidewalls of the arc-shaped plates b16 are evenly spaced along their axis with wire stripping blades 20, and the sidewalls of the arc-shaped plates a15 are evenly spaced along their axis with anti-slip ridges 19; the left and right ends of the outer walls of the wiring frame a3 and the wiring frame b4 are provided with adjusting screw holes 17, and adjusting screws 18 are screwed into the adjusting screw holes 17. The end of the adjusting screw 18 on one side is connected to the arc-shaped plate a15, and the end of the adjusting screw 18 on the other side is connected to the arc-shaped plate b16.

[0021] As the fundamental load-bearing component of the entire device, the terminal base 1 must possess high strength and stability. It can be made of high-strength engineering plastics or metal materials, such as aluminum alloy, which is lightweight, corrosion-resistant, and adaptable to the complex and varied construction environment of power engineering. Adjustable base plates a2 and b5 can be adjusted on the terminal base 1 to accommodate the spacing requirements of different wire specifications. The assembly method of both plates with the terminal base 1 should ensure flexible and stable adjustment. A sliding rail and slider combination can be used, with the sliding rail fixed to the terminal base 1 and the slider installed at the bottom of the adjusting base plates a2 and b5. The slider slides on the sliding rail to achieve position adjustment. A locking mechanism, such as bolt locking, is also provided. After adjustment to the appropriate position, the bolt is tightened to secure the adjusting base plate.

[0022] The dimensions of the wiring base 1 can be set according to common power engineering wiring scenarios, with a length of 300mm, a width of 200mm, and a thickness of 20mm; the adjustment base plate a2 and the adjustment base plate b5 have the same dimensions, with a length of 150mm, a width of 100mm, and a thickness of 10mm; the slide rail is 200mm long, which can allow the adjustment base plate to move flexibly within a certain range.

[0023] Several height-adjustable support feet are provided at the bottom of the wiring base 1. Each support foot consists of a screw and a nut. The extension length of the screw is adjusted by rotating the nut, so that the wiring base 1 remains horizontal on the uneven working surface, ensuring the accuracy and stability of the wiring operation.

[0024] Terminal frames a3 and b4 are used to support wires and provide space for wire clamping and stripping operations. The shape and size of the clamping cavity 14 must be compatible with the curved plates a15 and b16 to ensure that the curved plates can be stably installed and move smoothly within the clamping cavity. Terminal frames a3 and b4 can be made of insulating materials, such as polycarbonate, which has good insulation properties and mechanical strength, effectively preventing electric shock accidents and ensuring the safety of operators.

[0025] The height of the wiring frame a3 and the wiring frame b4 are 80mm and the width is 60mm. The depth of the clamping cavity 14 is 30mm and the width is 40mm, which can accommodate the placement and operation of common specification wires.

[0026] Identification slots are provided on the outer walls of wiring frames a3 and b4 for attaching labels indicating wire specifications and uses, facilitating quick identification and wiring operations by construction personnel. A protective cover is also provided on the top of the wiring frame. The cover is connected to the wiring frame via a hinge and can be closed when not in use to prevent dust and debris from entering the clamping cavity and affecting the wiring quality.

[0027] The curved plates a15 and b16 work together to clamp and strip the wire. The stripping blade 20 on the curved plate b16 is made of high-hardness alloy steel, such as SKD11, with a hardness of HRC60-62. It is sharp and durable, effectively stripping the wire's outer sheath. The stripping blade 20 can be designed with a serrated shape and a 30° cutting angle, ensuring effective stripping while avoiding excessive damage to the wire's internal conductive core. The anti-slip protrusions 19 increase friction with the wire, preventing it from slipping during clamping. The anti-slip protrusions 19 can be made of rubber with a certain surface roughness, generating significant friction when in contact with the wire.

[0028] The curvature of the arc plate a15 and the arc plate b16 matches the outer contour of common wires, with a radius of 20mm; the spacing of the wire stripping blades 20 is 5mm, and the number of wire stripping blades in each clamping cavity 14 is 8; the height of the anti-slip ridge 19 is 3mm, the width is 2mm, and the spacing between adjacent anti-slip ridges 19 is 4mm.

[0029] Guide chamfers with a chamfer angle of 45° are provided on the edges of the arc plate a15 and arc plate b16 to facilitate the smooth entry of the wire into the clamping cavity; wear detection marks are provided on the wire stripping blade 20. When the wire stripping blade is worn to a certain extent and the mark is exposed, the operator is prompted to replace the blade to ensure the wire stripping effect.

[0030] The adjusting screw 18, through its threaded engagement with the adjusting screw hole 17, adjusts the positions of the arc-shaped plates a15 and b16, thus accommodating the clamping requirements of wires of varying thicknesses. The adjusting screw 18 can be made of stainless steel to prevent rust from affecting the adjustment operation. A ball joint connection can be used between the end of the adjusting screw 18 and the arc-shaped plate, allowing the adjusting screw to rotate freely during adjustment and avoiding adjustment difficulties caused by angular deviations.

[0031] The diameter of the adjusting screw hole 17 is 8mm, the diameter of the adjusting screw 18 is 8mm, the pitch is 1.25mm, and the length of the adjusting screw 18 is set to 50mm according to the wiring frame size and adjustment requirements to ensure that the arc plate has sufficient adjustment stroke.

[0032] An adjustment handle is provided at the outer end of the adjustment screw 18. The adjustment handle can be circular with a diameter of 30mm and has anti-slip texture on the surface to facilitate the operator to apply force for adjustment. A scale mark is provided at the adjustment screw hole 17 to visually display the adjustment position of the arc plate, so as to accurately control the clamping force of the wire.

[0033] In some technical solutions, a positioning groove 7 is provided at the center of the top of the wiring base 1, and a spiral rod 8 is installed inside the positioning groove 7. A positioning screw hole 10 is provided on the side wall of the wiring base 1, and the positioning screw hole 10 is connected to the positioning groove 7. An internal threaded cylinder 13 is installed at the center of the bottom of the adjusting base plate a2 and the adjusting base plate b5, and the internal threaded cylinder 13 is screwed to the outside of the spiral rod 8.

[0034] By rotating the screw rod 8, the screw drive between the internal threaded cylinder 13 and the screw rod 8 enables the adjusting base plate a2 and the adjusting base plate b5 to move synchronously towards or away from each other on the wiring base 1. The rotation of the screw rod 8 can be done manually or by using an electric drive mechanism, such as a small motor, to improve adjustment efficiency. The positioning screw hole 10 and the positioning groove 7 are designed to lock the screw rod 8 after adjustment, preventing it from rotating due to external forces during wiring and causing a change in the position of the adjusting base plate.

[0035] The positioning groove 7 has a diameter of 12mm and a depth of 40mm; the spiral rod 8 has a diameter of 10mm and a length of 150mm; the internal threaded cylinder 13 has an inner diameter of 10mm and a height of 20mm; the positioning screw hole 10 has a diameter of 6mm, intersects the positioning groove 7 perpendicularly, and is locked with an M6 bolt.

[0036] Limiting blocks are set at both ends of the screw rod 8 to prevent the adjusting base plate a2 and adjusting base plate b5 from moving excessively and disengaging from the wiring base 1; anti-loosening washers are set at the positioning screw hole 10 to enhance the reliability of locking and prevent the bolts from loosening.

[0037] In some technical solutions, the end of the spiral rod 8 extends to the outside of the wiring base 1 and a turntable 11 is installed. The two ends of the spiral rod 8 are provided with two parts of external threads, and the threads of the two parts of external threads are opposite in direction.

[0038] The turntable 11 provides the operator with a force-applying area for rotating the screw rod 8. Its surface can be textured with anti-slip material to increase friction and facilitate operation. The two opposing external threads on the screw rod 8 allow the adjusting base plate a2 and adjusting base plate b5 to move synchronously in opposite directions when the screw rod 8 is rotated, ensuring the symmetry and stability of the adjustment. The turntable 11 and the screw rod 8 can be connected by a key to ensure synchronous rotation.

[0039] The diameter of the turntable 11 is 80mm and the thickness is 10mm; the length of the external thread at both ends of the screw rod 8 is 50mm and the pitch is 1.5mm, which can meet the needs of adjusting the spacing of the base plate within a large range.

[0040] An angle mark is set on the turntable 11. Each rotation of a certain angle corresponds to the movement distance of the adjustment base plate, which makes it convenient for operators to accurately control the adjustment distance. A sealing structure, such as a sealing ring, is set between the turntable 11 and the wiring base 1 to prevent dust and debris from entering the wiring base and affecting the normal rotation of the screw rod.

[0041] In some technical solutions, the top left and right sides of the terminal base 1 are provided with balance grooves 6, the balance grooves 6 are installed with balance shafts 9, and the bottom sides of the adjustment base plate a2 and adjustment base plate b5 are provided with balance cylinders 12, which are sleeved on the outside of the balance shafts 9.

[0042] The balancing structure, consisting of the balancing groove 6, the balancing shaft 9, and the balancing cylinder 12, effectively prevents the adjusting base plate a2 and the adjusting base plate b5 from tilting or shaking during adjustment, ensuring the stability and accuracy of the adjustment. The balancing shaft 9 needs to have high straightness and wear resistance; it can be made of 45# steel and surface hardened to a hardness of HRC45-50. The clearance between the balancing cylinder 12 and the balancing shaft 9 should be appropriate, ensuring smooth sliding of the balancing cylinder on the balancing shaft while also providing good guidance and balancing.

[0043] The balance groove 6 has a width of 15mm and a depth of 20mm; the balance shaft 9 has a diameter of 12mm and a length of 180mm to match the balance groove 6; the balance cylinder 12 has an inner diameter of 12.5mm, an outer diameter of 18mm, a height of 25mm, and a fitting clearance of 0.5mm.

[0044] End caps are installed at both ends of the balance shaft 9 to prevent the balance cylinder from falling off the balance shaft; grease, such as lithium-based grease, is applied to the inner wall of the balance cylinder 12 to reduce the frictional resistance between the balance cylinder and the balance shaft, making the adjustment smoother.

[0045] In some technical solutions, the anti-slip ridge 19 has a filling cavity 22 inside, and an elastic element 23 is installed inside the filling cavity 22.

[0046] The elastic element 23 can be a spring or a rubber elastomer. Its function is to generate a certain elastic deformation according to the thickness of the wire when clamping it, so that the anti-slip protrusion 19 can closely fit the surface of the wire and enhance the clamping effect. The spring can be a compression spring made of stainless steel, which has good elasticity and corrosion resistance; the rubber elastomer can be neoprene rubber, which has excellent weather resistance and elasticity.

[0047] The filling cavity 22 has a diameter of 1.5mm and a depth of 2mm; the spring has a diameter of 1.2mm, a free height of 3mm, and a compression strength of 5N set according to actual needs, which can ensure that it provides appropriate elastic force when clamping the wire;

[0048] A buffer layer, such as a sponge material, is provided between the elastic element 23 and the inner wall of the filling cavity 22 to prevent the elastic element from being damaged by friction with the inner wall of the filling cavity during long-term use; a sealing structure is provided at the end of the anti-slip protrusion 19 to prevent dust and debris from entering the filling cavity and affecting the performance of the elastic element.

[0049] In some technical solutions, the outer wall of the anti-slip ridge 19 is provided with anti-detachment ridges 21.

[0050] The function of the anti-detachment protrusion 21 is to further enhance the anti-detachment effect on the wire and prevent the wire from coming off the clamping part when it is pulled by external force. The anti-detachment protrusion 21 can adopt a triangular or trapezoidal structure, and its material is the same as that of the anti-slip protrusion 19. It is fixed to the outer wall of the anti-slip protrusion 19 by injection molding or bonding.

[0051] The anti-detachment protrusion 21 has a height of 1mm, a bottom width of 1.5mm, a top width of 1mm, and a spacing of 3mm between adjacent anti-detachment protrusions 21, which can provide a good anti-detachment effect without affecting the normal clamping of the wire;

[0052] The edges of the anti-detachment protrusion 21 are rounded with a radius of 0.2mm to prevent scratching the wire sheath when clamping and removing the wire; a wear-resistant coating, such as a ceramic coating, is applied to the surface of the anti-detachment protrusion 21 to improve its wear resistance and extend its service life.

[0053] Working process and principle:

[0054] I. Initial Adjustment Preparation

[0055] When using this electrical engineering wiring device for wiring operations, first adjust the positions of adjusting base plate a2 and adjusting base plate b5 according to the specifications and quantity of the wires to be connected. The operator rotates the turntable 11. Because the outer ends of the screw rod 8 have oppositely oriented external threads, and the internal threaded cylinders 13 at the bottom of adjusting base plate a2 and adjusting base plate b5 are screwed onto the screw rod 8, when the turntable 11 drives the screw rod 8 to rotate, adjusting base plate a2 and adjusting base plate b5 will move synchronously towards or away from each other. During this process, the balance shaft 9 in the balance groove 6 cooperates with the balance cylinders 12 at the bottom of adjusting base plate a2 and adjusting base plate b5 to ensure that the adjusting base plates do not tilt or shake during movement, ensuring the stability and accuracy of the adjustment. After adjusting base plate a2 and adjusting base plate b5 have moved to the appropriate positions, insert bolts through the positioning screw holes 10 and tighten them to lock the screw rod 8, thereby fixing the position of the adjusting base plates.

[0056] II. Wire Placement and Stripping

[0057] The wire to be wired is placed in the clamping cavity 14 of the wiring frame a3 and the wiring frame b4, with the wire positioned between the arc plate a15 and the arc plate b16. At this time, the wire stripping blade 20 on the side wall of the arc plate b16 will come into contact with the wire sheath. The wire stripping blade 20 is made of high-hardness alloy steel, and its serrated blade angle is 30°, which can effectively remove the wire sheath in subsequent operations while avoiding excessive damage to the internal conductive core of the wire.

[0058] III. Cable clamping and fixing

[0059] Next, the operator rotates the adjusting screw 18, which engages with the adjusting screw hole 17 on the outer wall of the wiring frame a3 and the wiring frame b4. Since one end of the adjusting screw 18 is connected to the arc plate a15 and the other end is connected to the arc plate b16, rotating the adjusting screw 18 will cause the arc plates a15 and b16 to move towards each other. As the arc plates a15 and b16 gradually approach each other, the anti-slip protrusion 19 on the side wall of the arc plate a15 comes into close contact with the surface of the wire. The elastic element 23 inside the anti-slip protrusion 19 deforms elastically according to the thickness of the wire, allowing the anti-slip protrusion 19 to better conform to the surface of the wire and increase friction. At the same time, the anti-detachment protrusion 21 on the outer wall of the anti-slip protrusion 19 further prevents the wire from coming off when pulled by external force, thereby achieving stable clamping of the wire.

[0060] IV. Wire stripping operation

[0061] As the curved plates a15 and b16 move towards each other to clamp the wire, the wire stripping blades 20 on the curved plate b16 gradually cut into the wire insulation as the plate moves. Because the stripping blades 20 are evenly distributed along the axis of the curved plate b16 and are sharp, they can quickly and effectively strip the wire insulation while it is being clamped. Once the curved plates a15 and b16 have moved to the appropriate positions, completing the clamping and stripping of the wire, the wire connection can then proceed.

[0062] V. Reset the device after wiring

[0063] After completing the wiring operation, rotate the adjusting screw 18 in the opposite direction to move the arc plate a15 and arc plate b16 in opposite directions, releasing the clamp on the wire and removing the connected wire. If it is necessary to wire other specifications, rotate the turntable 11 again to adjust the position of the adjusting base plate a2 and adjusting base plate b5, and repeat the above operation procedure.
