Description

Technical Field

[0001] This invention relates to the field of electrical connection technology, and in particular to an automatic stripping and crimping device for photovoltaic cables. Background Technology

[0002] As the global energy structure shifts towards cleaner and lower-carbon energy, photovoltaic power generation, as an important component of renewable energy, has developed rapidly in recent years. In large-scale ground-mounted photovoltaic power plants, distributed rooftop photovoltaic systems, and other projects, photovoltaic-specific cables are widely used for electrical connections between modules and between modules and inverters. Photovoltaic cables typically employ a double-insulation structure and possess excellent weather resistance, UV resistance, and high-temperature resistance to adapt to long-term outdoor operating environments.

[0003] During the on-site construction of photovoltaic systems, the cable core conductors need to be reliably electrically connected to the connectors. This connection process generally includes two key steps: first, precisely stripping the outer sheath of the cable core end to remove the insulation layer and expose the conductor of a specified length; second, inserting the exposed conductor into the connector terminals and achieving a low-resistance, high-mechanical-strength electrical connection through crimping. Currently, the above operations mainly rely on construction workers using manual wire strippers or knives to strip the insulation, and then using handheld crimping pliers to complete the terminal crimping. However, this traditional operation method has obvious drawbacks: First, manual stripping is difficult to guarantee dimensional consistency, easily causing conductor scratches, affecting connection reliability, and even causing safety hazards; second, the crimping quality is highly dependent on the operator's experience and skill level, and insufficient or excessive crimping may lead to increased contact resistance, excessive temperature rise, or insufficient mechanical strength; third, in the construction of large-scale photovoltaic projects, tens of thousands of cable joints need to be processed, and traditional operations are inefficient and labor-intensive, making it difficult to meet the needs of efficient, standardized, and batch construction. Summary of the Invention

[0004] In view of this, the present invention provides an automatic stripping and crimping device for photovoltaic cables, which can solve the shortcomings of existing photovoltaic cables when the core ends are processed by traditional operation methods, such as inconsistent stripping size, conductor damage, unstable crimping quality, low construction efficiency, and difficulty in meeting the needs of large-scale standardized operations.

[0005] The technical solution of this invention is as follows: an automatic stripping and crimping device for photovoltaic cables, comprising a column, threaded grooves on both sides of the outer wall of the column, and annular buckles at both ends of the column for fixing the cable. Nuts are threaded onto the threaded grooves on both sides of the column for deforming the annular buckles. Hollow cylinders are symmetrically arranged inside the column, with through holes for the cable core to pass through. Fixed blocks are symmetrically arranged inside the column, and movable cylinders are slidably arranged inside the fixed blocks. Sliding frames are symmetrically slidably arranged on the movable cylinders, and cutting blades for cutting the cable sheath are arranged on the sliding frames. Movable rods are slidably arranged at intervals on the hollow cylinders. Reset mechanisms are provided on both the movable cylinders and the sliding frames for resetting the movable cylinders and the sliding frames. A liquid infusion mechanism is provided inside the column for inputting liquid into the hollow cylinders, which then presses the movable rods to move. A limit mechanism is provided on the sliding frames, and conductive plates are connected to the limit mechanism for limiting the conductive plates. Wires are connected between the conductive plates.

[0006] As a preferred embodiment of the present invention, the end of the movable rod located on the outside of the hollow cylinder is provided with an inclined surface and a flat surface. The inclined surface is used to guide the symmetrical sliding frames on the movable cylinder to move closer to each other, while the flat surface is used to guide the symmetrical sliding frames on the movable cylinder to translate in the same direction.

[0007] As a preferred embodiment of the present invention, the reset mechanism includes a first spring and a second spring, with the first spring connecting the movable cylinders inside the two hollow cylinders, and the second spring connecting the sliding frame and the movable cylinder.

[0008] As a preferred embodiment of the present invention, the infusion mechanism includes a sliding block and a third spring. A cavity and a channel are spaced apart inside the cylinder. The cavity is used to store liquid. The two ends of the channel are connected to the cavity and the hollow cylinder, respectively. A sliding block for squeezing liquid is slidably arranged inside the cavity of the cylinder. A third spring is connected between the sliding block and the cylinder.

[0009] As a preferred embodiment of the present invention, the limiting mechanism includes a stop block, a movable frame, and a fourth spring. The stop block is installed on the side of the hollow cylinder, and the movable frame is slidably arranged on the sliding frame. The stop block is used to abut against the movable frame. The conductive sheet is connected to the movable frame, and the fourth spring is connected between the movable frame and the sliding frame.

[0010] As a preferred embodiment of the present invention, it further includes heat dissipation fins, with heat dissipation fins provided on the inner side of the column body, the heat dissipation fins being used to dissipate heat from the inner side of the column body.

[0011] As a preferred embodiment of the present invention, a sealing ring is also included. A sealing ring is provided on the inner side of the annular buckle, and the sealing ring is used to seal the annular buckle and the cable sheath.

[0012] As a preferred embodiment of the present invention, a sealing ring is also included. The sealing ring is provided at the end of the through hole of the hollow cylinder, and the sealing ring is used to seal the cable core and the hollow cylinder.

[0013] The beneficial effects of this invention are as follows: 1. When the cable is fixed by tightening the nut, the present invention can simultaneously drive the hydraulic fluid delivery mechanism, link the cutting blade to complete precise stripping, and drive the conductive sheet to press the conductor to achieve electrical connection. The whole process is simple to operate and effectively solves the problems of low efficiency, high labor intensity and difficulty in batch operation of traditional manual operation. It is suitable for the high-efficiency and standardized construction needs of large-scale photovoltaic power stations.

[0014] 2. The cutting blade of the present invention is precisely guided by the inclined surface and the plane of the movable rod to ensure consistent peeling length and no damage to the conductor; the conductive sheet is stably pressed against the conductor by the limiting mechanism and the spring reset system to form a low-resistance, high-mechanical-strength connection, avoiding safety hazards such as increased contact resistance, excessive temperature rise or connection failure caused by poor crimping.

[0015] 3. This invention integrates a sealing ring and a sealing ring to effectively prevent the intrusion of moisture, dust and corrosive gases; internal heat dissipation fins enhance thermal management and prevent excessive temperature rise; the overall structure is reliably sealed and has efficient heat dissipation, making it particularly suitable for harsh photovoltaic application scenarios such as high humidity, strong ultraviolet radiation and dust, extending the service life of the equipment and ensuring connection reliability.

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0030] Example: An automatic stripping and crimping device for photovoltaic cables, see below. Figures 1-11As shown, the device includes a column 1; it also includes an annular buckle 2, a nut 3, a hollow cylinder 4, a fixing block 5, a movable cylinder 6, a sliding frame 7, a cutting blade 8, a movable rod 9, a reset mechanism, an infusion mechanism, a limiting mechanism, a conductive sheet 13, and a wire 14; the column 1 has threaded grooves 101 on both the left and right sides of its outer wall; annular buckles 2 are provided at both ends of the column 1, and the annular buckles 2 are made of a metal material with high elasticity and fatigue resistance. The annular buckles 2 are used to fix the cable; nuts 3 are threaded onto the threaded grooves 101 on both sides of the column 1. When the nuts 3 are screwed into the threaded grooves 101, the inner wall of the nuts 3 will squeeze the annular buckles 2 and deform them inward to make them... A ring-shaped buckle 2 clamps the cable sheath for fixation; two hollow cylinders 4 are symmetrically arranged on the inner side of the column 1, and two through holes 401 are opened on the hollow cylinders 4 for the cable core to pass through; two fixing blocks 5 are symmetrically arranged on the inner side of the column 1, and the two fixing blocks 5 are located between the two hollow cylinders 4; two movable cylinders 6 are slidably arranged inside the fixing blocks 5, and the two movable cylinders 6 inside the fixing blocks 5 are distributed vertically. The two movable cylinders 6 on the same horizontal direction are spaced apart on the side that is close to each other, and the round holes are used for heat dissipation of the conductor of the cable core; sliding brackets 7 are slidably arranged between the front and rear sides of the two movable cylinders 6 inside the same fixing block 5, and sliding brackets 7 are slidably arranged on the same movable cylinder 6. Two sliding frames 7 are symmetrically distributed front and back; on the same side, the two sliding frames 7 are each equipped with a cutting blade 8 for cutting cable sheaths; on the side of the two hollow cylinders 4 that are close to each other, movable rods 9 are slidably arranged at intervals, with the two ends of the movable rods 9 located on the inner and outer sides of the hollow cylinders 4 respectively. The end of the movable rod 9 on the outer side of the hollow cylinder 4 is provided with an inclined surface and a flat surface. The inclined surface is used to guide the symmetrical sliding frames 7 on the movable cylinder 6 to move closer to each other, and the flat surface is used to guide the symmetrical sliding frames 7 on the movable cylinder 6 to translate in the same direction; both the movable cylinder 6 and the sliding frames 7 are equipped with a reset mechanism, which is used to drive the movable cylinder 6 and the sliding frames 7 to reset; an infusion machine is installed inside the column 1. The infusion mechanism is used to input liquid into the hollow cylinder 4. The liquid squeezes the movable rod 9 to move, and the movable rod 9 uses the inclined surface and flat surface at the end to guide the sliding frame 7 to move accordingly. The sliding frame 7 is equipped with a limit mechanism, and four sets of conductive plates 13 are connected to the limit mechanism. The four sets of conductive plates 13 are distributed in four directions: front-lower, front-upper, rear-lower, and rear-upper. There are two conductive plates 13 in each set. The two conductive plates 13 in the same set are symmetrically distributed from left to right. A wire 14 is connected between the two conductive plates 13 in the same set, and the wire 14 passes through two fixed blocks 5. The conductive plates 13 are used to contact the conductor in the cable core. The limit mechanism is used to limit the conductive plates 13.

[0031] See Figure 3 , Figure 4 and Figure 6As shown, the reset mechanism includes a first spring 1001 and a second spring 1002; the first spring 1001 is connected between the two movable cylinders 6 in the same horizontal direction; the second spring 1002 is connected between the sliding frame 7 and the movable cylinder 6.

[0032] See Figure 8 As shown, the infusion mechanism includes a sliding block 1103 and a third spring 1104; four cavities 1101 are symmetrically opened on the inner side of the column 1, and the cavities 1101 are used to store hydraulic oil; four channels 1102 are symmetrically opened on the inner side of the column 1, and the two ends of the channels 1102 are respectively connected to the cavities 1101 and the hollow cylinder 4; a sliding block 1103 for squeezing liquid is slidably arranged in the cavity 1101 of the column 1, and the nut 3 will gradually approach the sliding block 1103 when it is screwed into the threaded groove 101 until it squeezes the sliding block 1103 to move; a third spring 1104 is connected between the sliding block 1103 and the inner side of the column 1.

[0033] See Figure 9 , Figure 10 and Figure 11 As shown, the limiting mechanism includes a stop block 1201, a movable frame 1202, and a fourth spring 1203; a stop block 1201 is installed on the side of each of the two hollow cylinders 4 that are close to each other, and the two stop blocks 1201 are distributed left and right, with inclined surfaces on both the front and rear sides of the stop block 1201; movable frames 1202 are slidably arranged on the side of the sliding frame 7 facing the hollow cylinder 4 on the same side, and there are four movable frames 1202, which are distributed in four directions: left front, left rear, right front, and right rear. The inclined surfaces on the front and rear sides of the stop block 1201 are used to stop the same... Two movable frames 1202 on one side have two conductive plates 13 on the upper front side connected to the top of the movable frames 1202 on the left and right front sides respectively, and two conductive plates 13 on the lower front side connected to the bottom of the movable frames 1202 on the left and right front sides respectively. Two conductive plates 13 on the upper rear side are connected to the top of the movable frames 1202 on the left and right rear sides respectively, and two conductive plates 13 on the lower rear side are connected to the bottom of the movable frames 1202 on the left and right rear sides respectively. Two fourth springs 1203 are connected between the movable frame 1202 and the sliding frame 7 on the same side.

[0034] In the initial state, the inclined surface at the end of the movable rod 9 is in contact with the sliding frame 7 (e.g., Figure 5 As shown), the cavity 1101, the channel 1102 and the hollow cylinder 4 are all filled with hydraulic oil. The inclined surfaces on the front and rear sides of the abutment block 1201 abut against the two movable frames 1202 on the same side, so that the fourth spring 1203 is in a compressed state. When in use, first insert the ends of the two cables into the inner side of the annular buckles 2 on both sides, so that the cable cores at the ends of the cables enter the through holes 401 of the hollow cylinder 4, and pass through the through holes 401 into the inner side of the movable cylinder 6, so that the ends of the cable cores abut against the inner wall of the movable cylinder 6. Then, the nut 3 is screwed into the threaded groove 101. As the nut 3 is gradually screwed into the threaded groove 101, the inner wall of the nut 3 will compress the annular buckle 2, causing it to gradually converge inward through deformation, thus clamping the outer sheath of the cable and fixing the cable. When the nut 3 is screwed into the threaded groove 101 and contacts the sliding block 1103, the nut 3 will push the sliding block 1103 to move inward into the cavity 1101. The third spring 1104 is compressed, causing the sliding block 1103 to squeeze the hydraulic oil in the cavity 1101. This causes the hydraulic oil in the cavity 1101 to be pressurized and flow into the hollow cylinder 4 through the channel 1102, gradually increasing the amount of hydraulic oil inside the hollow cylinder 4. This causes the hydraulic oil inside the hollow cylinder 4 to compress the movable rod 9, which extends out of the hollow cylinder 4. As the movable rod 9 extends from the hollow cylinder 4, the inclined surface at the end of the movable rod 9 will first press the two sliding frames 7 on the same side closer to each other. The second spring 1002 is compressed, causing the cutting blade 8 on the sliding frame 7 to gradually approach the outer sheath of the cable core, thereby cutting the outer sheath of the cable core. After the inclined surface at the end of the movable rod 9 separates from the sliding frame 7, the flat surface at the end of the movable rod 9 will contact the sliding frame 7. Subsequently, the flat surface at the end of the movable rod 9 will drive the sliding frame 7 and the movable cylinder 6 to move towards the center of the column 1. The first spring 1001 is compressed, causing the cutting blade 8 on the sliding frame 7 to push the cut outer sheath towards the center of the column 1, thereby exposing the conductor inside the cable core. In this way, automatic stripping of the cable core end can be achieved. When the sliding frame 7 moves towards the center of the column 1, the sliding frame 7 will drive the movable frame 1202 and the conductive plate 13 to move towards the center of the column 1, so that the movable frame 1202 separates from the inclined surface of the abutment block 1201. When the movable frame 1202 separates from the inclined surface of the abutment block 1201, under the elastic force of the fourth spring 1203, the fourth spring 1203 will drive the movable frame 1202 to move towards the side closer to the core conductor, thereby driving the conductive plate 13 to come close to the exposed conductor, so that the conductive plate 13 presses against the exposed conductor (before this step, the cutting blade 8 has already pushed the cut outer sheath towards the side closer to the center of the column 1, thereby ensuring that the conductor can expose a sufficient area to contact the conductive plate 13), so that the core conductors of the two cables are connected through the conductive plate 13 and the wire 14, thus completing the connection of the two cables; When it is necessary to disconnect the two cables, the nut 3 is turned out of the threaded groove 101. As the nut 3 is gradually turned out of the threaded groove 101, the inner wall of the nut 3 will gradually loosen the annular buckle 2, allowing the annular buckle 2 to gradually return to its original state. This allows the annular buckle 2 to loosen the outer sheath of the cable, thereby releasing the cable from its fixation. At the same time, when the nut 3 is turned out of the threaded groove 101 and separates from the sliding block 1103, the third spring 1104, the first spring 1001, and the second spring 1002 return to their original state. The third spring 1104 drives the sliding block 1103 to move and reset to the outside of the cavity 1101, increasing the space inside the cavity 1101. At this time, the hydraulic oil flows back from the hollow cylinder 4 through the channel 1102 into the cavity 1101 under the action of pressure difference. The first spring 1001 drives the movable cylinder 6 and the sliding frame 7 to move and reset to the side away from the center of the column 1. The second spring 1002 drives the two sliding frames 7 on the same side to move away from each other and reset, so that the sliding frame 7... As the cutting blade 8 gradually moves away from the cable core, the sliding frame 7 moves and resets, gradually separating from the plane at the end of the movable rod 9 and re-contacting the inclined surface at the end of the movable rod 9, thus retracting the movable rod 9 into the hollow cylinder 4 to complete the reset. When the sliding frame 7 moves and resets to a side away from the center of the column 1, the sliding frame 7 will drive the movable frame 1202 and the conductive plate 13 to move and reset to a side away from the center of the column 1. When the movable frame 1202 contacts the inclined surface of the abutment block 1201, the abutment block 1201 will press the movable frame 1202 to move and reset to a side away from the cable core conductor through the inclined surface. The fourth spring 1203 is compressed, thereby driving the conductive plate 13 away from the conductor, separating the conductive plate 13 from the conductor, thus disconnecting the cable core conductors of the two cables. Then, the ends of the two cables are pulled out from the inside of the annular buckles 2 on both sides, and the stripped outer sheath is hooked out from the inside of the movable cylinder 6 through the through hole 401 using a hook.

[0035] See Figure 12 As shown, it also includes heat dissipation fins 15; heat dissipation fins 15 are provided in the middle of the inner side of the column 1. The heat dissipation fins 15 are used to effectively improve the heat dissipation efficiency inside the column 1. By increasing the contact area between the inner side of the column 1 and the air, heat conduction and convection are accelerated, thereby reducing the internal temperature rise, ensuring the long-term stable operation of the device, and improving the safety and reliability of the electrical connection.

[0036] See Figure 12 As shown, it also includes a sealing ring 16; the sealing ring 16 is provided on the inner side of the annular buckle 2. The sealing ring 16 can form a reliable sealing interface between the annular buckle 2 and the cable sheath, effectively preventing external moisture, dust, corrosive gases and other environmental pollutants from seeping into the device along the cable sheath, avoiding hydraulic oil contamination, metal component corrosion or conductor oxidation, thereby improving the environmental adaptability of the device (such as being suitable for harsh working conditions such as high humidity and sandstorms in outdoor photovoltaic power stations) and extending its service life.

[0037] See Figure 4 As shown, it also includes a sealing ring 17; the end of the through hole 401 of the hollow cylinder 4 facing the same side of the annular buckle 2 is provided with a sealing ring 17. The sealing ring 17 can achieve dynamic sealing at the through hole 401 where the cable core passes through the hollow cylinder 4. Since the cable core may have slight displacement during the stripping and crimping process, the sealing ring 17 can not only allow the cable core to pass through smoothly, but also fit tightly against the outer surface of the cable core in the working state, further preventing external moisture, dust, corrosive gases and other environmental pollutants from seeping into the device along the cable sheath.
