Description
Technical Field
[0001] The present invention relates to the technical field of wire connection, and in particular to a wiring device and a wiring method for electric power facilities. Background Art
[0002] Wiring devices are key components used in electrical engineering to connect, switch, or tap wires. They are widely used in power systems, industrial control, and equipment maintenance. Wire connections are essential for the construction and maintenance of power facilities, and the quality of these connections directly impacts the safe and stable operation of the power system.
[0003] Traditional wiring operations present numerous inconveniences. First, the wire insulation must be manually stripped using specialized tools like wire strippers, a tedious process. Furthermore, after stripping, the exposed wires must be secured to the terminal blocks using screws or crimping. This entire process requires the use of multiple tools, resulting in low efficiency. This is particularly challenging when working at height or in confined spaces, where carrying and using tools is extremely inconvenient.
[0004] Most existing wiring devices offer only simple wiring functions and fail to achieve integrated stripping and wiring operations. While some improved wiring devices have emerged on the market, they still suffer from issues such as incomplete stripping and loose connections. The complex operation process also makes quick wiring difficult. Furthermore, existing devices often lack effective insulation stripping guides, which can lead to inconsistent stripping lengths and compromise wiring quality. Summary of the Invention

[0009] Optionally, the wire stripping assembly includes a wire stripping block, which is fixedly connected to the inner wall of the base and abuts against the side of the lower fixed block away from the wiring hole, the top of the wire stripping block is fixedly connected to a sliding rod, the top of the sliding rod is fixedly connected to a baffle, and the side surface of the sliding rod is movably sleeved with a movable block; the side of the movable block opposite to the wire stripping block is provided with a sharp incision and formed with a cutter, and the movable block slides to cut into the insulation layer of the wire; the junction box is also provided with a driving assembly for driving the movable block to slide.
[0010] Optionally, the driving assembly includes a first spring, which is installed on the side of the movable block opposite to the baffle, and the first spring is sleeved on the sliding rod. When the first spring is in a natural state, the movable block abuts against the stripping block; the junction box is also provided with a limit assembly for limiting the expansion and contraction of the first spring.
[0011] Optionally, the limit assembly includes a fixed plate and a limit baffle, the limit baffle is slidably connected in the junction box and is located on the wire movement path, the fixed plate is fixedly set in the junction box, a second spring is provided between the fixed plate and the limit baffle, and a baffle rod is fixedly connected to the upper part of the limit baffle. When the second spring is in a natural state, the baffle rod is located on the movement path of the movable block and the movable block is separated from the stripping block.
[0012] Optionally, a cover is fixedly connected to the top of the base, a through hole is opened on one side of the cover, a guide tube is fixedly connected to the inner wall on the opposite side of the base, and a guide tube identical to that on the base is fixedly connected to the inner wall on the opposite side of the cover.
[0013] Optionally, the stripping block and the movable block jointly form a tapered stripping groove for the conductor wire to pass through, and the diameter of the stripping groove on one side close to the limit baffle is smaller than the diameter on the other side.
[0014] In a second aspect, the present application provides a wiring method for electric power facilities, which adopts the following technical solution:
[0015] A wiring method for electric power facilities comprises the following steps:
[0016] S1: Place the through hole on the wiring device downward, then insert the end of the wire into the guide tube. The end of the wire passes through the guide tube and the placement slot in sequence. The end of the wire pushes one side of the V-shaped spring to disengage the spring from the slot.
[0017] S2: The end of the wire continues to go deeper and pass through the tapered stripping groove until the end of the wire abuts against the limit baffle. As the wire continues to be fed, the limit baffle overcomes the force of the second spring, causing the limit baffle to move until the baffle rod is disengaged from the movable block. As a result, the movable block, under the action of the first spring, clamps the wire toward the stripping block, causing the incision formed between the movable block and the stripping block to radially cut the wire.
[0018] S3: Pull back the wire. The cutter formed by the tapered stripping groove, stripping block and movable block cuts the wire surface in a circular manner. Under the pulling force of the operator, the insulation layer on the wire cut by the cutter is separated. As the wire is pulled continuously, the insulation layer at the end of the wire falls off and the inner core is exposed.
[0019] S4: When the wire core moves to the slot, the deformation ability is poor because it is originally protected by the insulation layer. The wire core has a stronger deformation ability than the wire protected by the insulation layer. After the wire core moves to the slot, the elastic deformation force of the spring forces the wire core to be pressed into the slot by the spring and connected to the conductive strip in the slot, thus completing the connection of the two wires.
[0020] From the above, it can be seen that the present application provides a wiring device and wiring method for power facilities, which automatically completes the insulation stripping and realizes the reliable connection between the wire core and the conductive strip when the wire is inserted by integrating the wire stripping component and the fastening component, solving the problems of cumbersome tool switching, unstable wire stripping quality and low wiring efficiency in traditional operations. It has the advantages of improving wiring efficiency, simplifying operating procedures, ensuring wire stripping quality and realizing the integration of wire stripping and wiring.

[0026] The following is combined with Figure 1-3 This application is described in further detail.
[0027] The present application proposes a power facility wiring device including a junction box. The junction box has wiring holes 11 at both ends for inserting wires, and a base 1 with a built-in conductive strip 12. The junction box integrates a wire stripping assembly 2 and a fastening assembly 3, wherein the fastening assembly 3 includes a lower fixing block 301 and an upper fixing block 304, which are fixedly connected to form an internal through-hole placement slot 302. A slot 303 is defined at the bottom of the lower fixing block 301, and the end of the conductive strip 12 is exposed in the slot 303. A V-shaped spring clip 305 is provided on the side of the upper fixing block 304, and the lowest end of the spring clip 305 is embedded in the slot 303.
[0028] After the wire is inserted through the wiring hole 11, it moves along the placement groove 302, and the V-shaped spring clip 305 is elastically deformed by the compression of the wire. After the insulation layer of the wire is stripped off, the overall toughness of the wire decreases due to the stripping of the insulation layer, and the exposed wire core is pressed into the slot 303 under the action of the restoring force of the spring clip 305, forming a surface contact with the conductive bar 12. The depth of the slot 303 matches the thickness of the conductive bar 12 to ensure that the contact surface of the wire core and the conductive bar 12 are in the same plane. The design of the lowest end of the spring clip 305 embedded in the slot 303 generates a component force perpendicular to the bottom surface of the slot 303 when the spring clip 305 is deformed, thereby enhancing the contact pressure between the wire core and the conductive bar 12. The connecting layout of the placement groove 302 and the wiring hole forms a continuous wire channel, ensuring that the wire direction does not need to be manually adjusted during the insertion process.
[0029] Through the above technical solution, the present application realizes the simultaneous completion of the stripping of the wire insulation layer and the fixing of the wire core, without the need for additional tools during the operation. The synergistic effect of the V-shaped spring 305 and the card slot 303 ensures that the wire core and the conductive bar 12 form a stable electrical connection, avoiding the contact resistance fluctuation caused by uneven manual crimping force. The through-design of the placement slot 302 simplifies the wire insertion path and reduces the difficulty of operation. It is particularly suitable for wiring operations in distribution boxes with limited space.
[0030] In this embodiment, the wire stripping assembly 2 includes a wire stripping block 201, which is fixedly connected to the inner wall of the base 1 and abuts against the side of the lower fixed block 301 away from the wiring hole. The top of the wire stripping block 201 is fixedly connected to a slide rod 202, and the top of the slide rod 202 is fixedly connected to a baffle 203. The side surface of the slide rod 202 is movably connected to a movable block 206; the side of the movable block 206 opposite to the wire stripping block 201 is provided with a sharp incision and formed with a cutter, and the movable block 206 slides to cut into the insulation layer of the wire; the junction box is also provided with a driving assembly for driving the movable block 206 to slide.
[0031] The stripping block 201 is a rigid support structure fixed to the inner wall of the base 1, forming a reference plane for the cutting operation. The slide bar 202 is an axial guide component, which can be implemented as an insulated optical axis. It is fixed vertically to the top of the stripping block 201 to form a sliding track for the movable block 206. The movable block 206 is a movable cutting component that is mounted on the slide bar 202. Its sharp cutting edge opposite the stripping block 201 forms an annular cutting edge. The drive assembly is the power mechanism that triggers the sliding of the movable block 206. Specifically, it can be implemented as a spring energy storage device, which automatically triggers the cutting action when the wire is in place.
[0032] Specifically, the stripping block 201 forms a spatial positioning reference by abutting against the lower fixed block 301, ensuring that the cutter maintains a perpendicular relationship with the conductor axis. When the conductor is inserted into place, the drive assembly releases the pre-stored energy to push the movable block 206 to slide axially along the slide bar 202. The sharp cut between the movable block 206 and the stripping block 201 forms a radial shear force, causing the cutter to penetrate deep into the insulation layer. The rigid support of the slide bar 202 enables the movable block 206 to maintain a linear motion trajectory, and the baffle 203 acts as a mechanical limit to prevent the movable block 206 from detaching from the slide bar 202. During the sliding process, the cutter cuts into the insulation layer of the conductor to form a circular cut, and the relative movement of the movable block 206 and the stripping block 201 produces a progressive cutting depth until the insulation layer is completely cut off. The automatic triggering mechanism of the drive assembly links the cutting action with the insertion of the conductor, and the stripping operation can be completed without manual intervention.
[0033] Through the above-mentioned technical solution, this application achieves automated wire insulation stripping, eliminating the efficiency loss caused by tool switching in traditional operations. Mechanical control of cutting depth effectively prevents wire core damage and ensures the reliability of electrical connections. The timing coordination of the drive assembly and the wiring process allows the stripping operation to be seamlessly integrated into the wire insertion process, significantly improving the overall efficiency of wiring operations.
[0034] In this embodiment, the driving assembly includes a first spring 204, which is installed on the side of the movable block 206 opposite to the baffle 203. The first spring 204 is sleeved on the slide rod 202. When the first spring 204 is in a natural state, the movable block 206 abuts against the stripping block 201; the junction box is also provided with a limit assembly 7 for limiting the extension and contraction of the first spring 204.
[0035] The first spring 204 is mounted on the outer surface of the slide bar 202 to constrain radial displacement, storing elastic potential energy in a pre-compressed state. The limiter assembly 7 is a mechanical structure used to constrain the motion path of the movable block 206. Specifically, this is achieved by the cooperation of a sliding baffle and a fixed plate 701. The contact between the baffle bar 703 and the movable block 206 creates a physical limit, preventing premature release of the spring.
[0036] Specifically, when the wire is not fully inserted, the stop rod 703 of the limit assembly 7 blocks the moving path of the movable block 206. At this time, the first spring 204 is in a compressed state but cannot drive the movable block 206 to slide. When the end of the wire pushes the limit baffle 704 to overcome the resistance of the second spring 702, the stop rod 703 disengages from the moving path of the movable block 206, and the elastic force of the first spring 204 drives the movable block 206 to slide axially along the slide rod 202, so that the cutter cuts into the insulation layer of the wire. During the sliding process of the movable block 206, the slide rod 202 provides an axial guiding function to prevent the cutter from offsetting and causing uneven cutting depth. After the cutting is completed, when the external force pulls the wire back, the movable block 206 is blocked by the stripping block 201 and cannot continue to slide. The first spring 204 is still in a compressed state to ensure that it will not rebound during the subsequent pulling back process.
[0037] In an embodiment of the present application, the limiting assembly 7 includes a fixed plate 701 and a limiting baffle 704. The limiting baffle 704 is slidably connected in the junction box and is located on the moving path of the wire. The fixed plate 701 is fixedly arranged in the junction box. A second spring 702 is provided between the fixed plate 701 and the limiting baffle 704. A blocking rod 703 is fixedly connected to the limiting baffle 704. When the second spring 702 is in a natural state, the blocking rod is located on the moving path of the movable block 206 and the movable block 206 is separated from the stripping block 201.
[0038] When the wire is not fully inserted, the second spring 702 holds the stop plate 704 in its initial position. The stop rod 703 blocks the movement of the movable block 206, separating it from the stripping block 201. When the wire is inserted to the desired depth, the wire end pushes the stop plate 704, overcoming the resistance of the second spring 702 and causing the stop rod 703 to move out of the path of the movable block 206. The drive assembly then forces the movable block 206 to slide toward the stripping block 201, allowing the cutter formed by the two to penetrate the wire insulation.
[0039] Through the above-mentioned technical solution, the present application achieves precise synchronous control of the wire stripping action and the insertion depth of the wire, ensuring that the wire stripping operation is initiated only after the wire is fully in place, avoiding incomplete insulation stripping caused by premature cutting or damage to the wire core caused by late cutting. This structure completes the action triggering and resetting in a purely mechanical manner, without the need for external energy supply, and can still maintain stable operation under complex working conditions. The coordinated design of the limit baffle 704 and the baffle rod 703 ensures that the wire stripping assembly 2 is in a reliably locked state when not in operation, preventing the occurrence of false operations.
[0040] The present application further proposes that a cover 5 is fixedly connected to the top of the base 1, a through hole 6 is opened on one side of the cover 5, a guide tube 4 is fixedly connected to the inner wall on the opposite side of the base 1, the guide tube 4 is located on the wiring hole 11, and a guide tube 4 identical to that on the base 1 is fixedly connected to the inner wall on the opposite side of the cover 5.
[0041] The present application further proposes that the stripping block 201 and the movable block 206 jointly form a tapered stripping groove 205 for the conductor wire to pass through, and the diameter of the stripping groove 205 on one side close to the limit baffle 704 is smaller than the diameter on the other side.
[0042] Specifically, when a wire passes through the tapered stripping groove 205, the larger diameter end guides the wire in. As the wire reaches the smaller diameter end, the sidewalls of the stripping groove 205 radially constrain the wire. As the spring forces the movable block 206 toward the stripping block 201, the cut formed by the two gradually cuts into the insulation along the tapered surface. During wire retraction, the tapered structure generates circumferential shear force, stripping only the insulation and avoiding damage to the wire core. The smaller diameter design near the stopper 704 ensures that the cutting action is triggered synchronously with the wire reaching the predetermined position, achieving sequential control of positioning and stripping.
[0043] Through the above-mentioned technical solution, the present application achieves a one-time circular stripping of the wire insulation layer, limiting the cutting depth to within the insulation thickness range, effectively preventing wire core damage. The guiding effect of the tapered stripping groove 205 eliminates the need for precise alignment during operation, simplifying the wiring process. The coordinated control of the cutting action and wire positioning avoids the cumbersome step-by-step operation required in traditional methods.
[0044] This application further proposes a wiring method for electric power facilities, comprising the following steps:
[0045] S1. Place the through hole 6 on the wiring device downward, then insert the end of the wire into the guide tube 4. The end of the wire passes through the guide tube 4 and the placement slot 302 in sequence. The end of the wire pushes one side of the V-shaped spring piece 305, causing the spring piece 305 to disengage from the locking slot 303.
[0046] S2, the end of the wire continues to go deeper, passing through the tapered stripping groove 205 until the end of the wire abuts against the limit baffle 704. As the wire continues to be fed, the limit baffle 704 overcomes the force of the second spring 702, causing the limit baffle 704 to move until the stop rod 703 is separated from the movable block 206, so that the movable block 206, under the action of the first spring 204, clamps the wire toward the stripping block 201, so that the incision formed between the movable block 206 and the stripping block 201 cuts the wire radially;
[0047] S3, pulling back the wire, and the cutter formed by the tapered stripping groove 205, the stripping block 201 and the movable block 206 circumferentially cuts the surface of the wire. Under the pulling force of the operator, the insulation layer on the wire cut by the cutter is separated. As the wire is pulled continuously, the insulation layer at the end of the wire falls off and the inner core is exposed;
[0048] S4. When the wire core moves to the position of the slot 303, since the position is originally protected by an insulating layer, the deformation ability is poor, and the wire core has a stronger deformation ability than the wire protected by the insulating layer. After the wire core moves to the slot 303, the elastic deformation force of the spring piece 305 forces the wire core to be pressed into the slot 303 by the spring piece 305 and connected to the conductive bar 12 in the slot 303, thereby completing the wiring of the two wires.
[0049] Through the above technical solution, the present application realizes the integrated operation of wire stripping and electrical connection. The operator only needs to complete the two actions of insertion and retraction to automatically complete the insulation stripping and wire core crimping. This method avoids the use of wire strippers in traditional processes, reducing tool preparation time and the probability of operational errors. The combination of the tapered stripping groove 205 and the spring-driven cutter ensures the controllable cutting depth of the insulation layer and prevents damage to the internal conductor. The spring 305 crimping mechanism utilizes the difference in physical properties between the wire core and the insulation layer to ensure the reliability of the electrical connection while preventing the insulation material from being accidentally pressed into the conductive area.
[0050] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
