Description
Technical Field
[0001] This invention relates to the field of wiring device technology, and more specifically to a wiring device for preventing burnout in a photovoltaic power generation system. Background Technology
[0002] Photovoltaic power generation is a technology that directly converts light energy into electrical energy using the photovoltaic effect at the semiconductor interface. It mainly consists of solar panels, controllers, and inverters, with the main components being electronic devices. When setting up circuits in a photovoltaic power generation system, wiring devices are often used to connect the various components in the system. However, when using existing wiring devices, the internal temperature of the connection points may rise due to various reasons such as loose lead wires or abnormal operation of components. In severe cases, this may even lead to a fire. Although the probability of this problem is low, if it does occur and the connection is not cut off in time, it may cause the connection point of the line to burn out and affect the operation of other components, posing a certain safety hazard. Summary of the Invention
[0003] To overcome the aforementioned technical problems, the present invention aims to provide a burn-out prevention wiring device in a photovoltaic power generation system. Two sliding frames are slidably connected to the top surface of a mounting plate. Two corresponding wiring modules can be connected via conductive rods. Wires can then be placed on the terminal blocks. A temperature sensor monitors the internal temperature of the enclosure. When the temperature at the connection point rises, an adjustment mechanism separates the two sliding frames, thereby separating the two corresponding terminal blocks located on different sliding frames, disconnecting the circuit, preventing further temperature increases and potential fire inside the enclosure, and improving safety.
[0004] The objective of this invention can be achieved through the following technical solutions: A wiring protection device for preventing burnout in a photovoltaic power generation system includes a housing with a cover plate on the top surface. An adjustment module is located inside the housing. The adjustment module includes a mounting plate, with two sliding frames slidably connected to each other on the top surface of the mounting plate. Several sliding seats are slidably connected to the top surfaces of the sliding frames. A wiring module is located on the inner side of each sliding seat. The wiring module includes a terminal block. Two adjacent terminal blocks located on different sliding frames have insertion slots at their closest ends, and the other end of each terminal block has a wiring hole. A conductive block is embedded in the bottom surface of the insertion slot. A conductive rod is slidably connected to the inner side of the insertion slot, contacting the top surface of the conductive block. The conductive rod is slidably inserted into the inner side of the insertion slot of an adjacent terminal block, and two adjacent conductive rods are in contact with each other. An adjustment mechanism for adjusting the position of the sliding frames is located on the top surface of the mounting plate. A temperature sensor is located inside the housing.
[0005] Several wiring modules can be installed on both sliding frames, with each module corresponding to the previous one. Wires can be connected to the wiring holes on the terminal blocks, and the wire ends are pressed into the corresponding holes using the clamping screws on the terminal blocks. The insertion slots of the two terminal blocks on different sliding frames correspond to each other, allowing the conductive rod of one terminal block to be inserted into the insertion slot of the other terminal block. This makes the conductive rod contact the conductive block in the insertion slot, and the two adjacent conductive rods contact each other, thus enabling the two corresponding terminal blocks to conduct electricity through the mutual insertion of the conductive rods. A temperature sensor can monitor the internal temperature of the enclosure. If a problem occurs at the connection point of the terminal block, causing it to overheat, the two sliding frames can be moved away from each other using an adjustment mechanism, thereby separating the terminal blocks on the two sliding frames, disconnecting the circuit, preventing the terminal blocks from burning out due to continuous temperature rise, and preventing a fire inside the enclosure. This improves the safety factor.
[0006] Furthermore, the adjustment mechanism includes two fixed frames and two bidirectional lead screws. The bottom surface of the fixed frame is fixedly connected to the long side of the top surface of the mounting plate. Both ends of the fixed frame are rotatably connected to the sides of the two bidirectional lead screws. Two sliding blocks that are slidably connected to the top surface of the mounting plate are screwed onto the sides of the bidirectional lead screws. Both ends of the sliding frame are fixedly connected to the sides of adjacent sliding blocks. One end of each of the two bidirectional lead screws is located inside one fixed frame and is fixedly fitted with a pulley, and the two pulleys are connected by a belt drive. The other end of one bidirectional lead screw is located inside another fixed frame and is fixedly fitted with a transmission gear. An adjustment motor is provided on the bottom surface of the housing corresponding to the transmission gear. The output end of the adjustment motor is driven by a transmission shaft. A connecting shaft is rotatably connected to the inner side of the mounting plate corresponding to the transmission shaft. Connecting gears are fixedly fitted on the sides of both the connecting shaft and the transmission shaft. The two connecting gears mesh and drive each other. When the temperature sensor detects an increase in the internal temperature of the housing, it can start the regulating motor, which drives the transmission shaft to rotate. The transmission shaft can drive the connecting shaft to rotate through the connecting gear. The connecting shaft will drive a double-acting screw to rotate through the connecting gear and the transmission gear. One double-acting screw can drive another double-acting screw to rotate through a pulley. When the double-acting screw rotates, the two sliding blocks on the same double-acting screw will move in opposite directions. The sliding blocks can drive the sliding frame to move, thereby causing the two sliding frames to move in opposite directions, separating the two corresponding sets of two terminal blocks from each other. This causes the conductive rod in one terminal block to disengage from the plug slot in the other terminal block. Even if the conductive rods of the two terminal blocks are separated from each other, the circuit is disconnected at the terminal block to prevent further heating and fire.
[0007] Furthermore, the inner side of the sliding frame is provided with several X-shaped frames corresponding to the sliding seat, and the two ends of adjacent X-shaped frames are rotatably connected. The top of the shaft of the X-shaped frame is rotatably connected to a limiting block that is slidably connected to the top inner side of the sliding frame, and the top surface of the limiting block is fixedly connected to the bottom surface of the sliding seat. Several X-shaped frames can form a telescopic frame. The limiting block can restrict the position of the X-shaped frame and lengthen the telescopic frame. At this time, the limiting blocks on the X-shaped frame will be evenly separated. The limiting block can drive the sliding seat to move, thereby separating several sliding seats and evenly separating several terminal blocks on the same sliding frame. This is beneficial to improving the safety factor and also facilitates heat dissipation of the heated terminal blocks, preventing the terminal blocks from burning out.
[0008] Furthermore, the mounting plate has a mounting groove on its top surface, and limit rails are fixedly connected to the four corners of the inner side of the mounting groove. Adjustment seats are slidably connected to both sides of the inner side of the sliding frame. The side of the adjustment seat is slidably connected to the end of the adjacent X-shaped frame. A circular block is fixedly connected to the bottom of the adjustment seat and slidably connected to the inner side of the adjacent limit rail. When the sliding frame moves, it can drive the circular block to move along the limit rail. After the conductive rods of the two terminals separate from each other, the circular block continues to move and will move to the corner of the limit rail. The circular block will continue to move obliquely along the inclined section of the limit rail, so that the circular block moves towards the end of the sliding frame. The circular block can drive the end of the adjustment seat to move, so that the two adjustment seats in the sliding frame move in opposite directions. At this time, the adjustment seat can stretch the telescopic frame composed of several X-shaped frames, so that several terminals separate from each other.
[0009] Furthermore, the inner side of the mounting groove is rotatably connected to two partitions corresponding to the sliding frame. The inner side of each partition is rotatably connected to a fixed shaft that is fixedly connected to the inner side of the mounting groove. A torsion spring is provided between the side of the fixed shaft and the inner side of the partition. When the two sliding frames move in opposite directions and separate from the adjacent partitions, the partitions can rotate upward under the action of the torsion springs. In this way, the partitions can block the corresponding terminal blocks on the two sliding frames, thereby further improving the safety factor.
[0010] Furthermore, the top surface of the sliding seat is fixedly connected to a limiting frame that slides into one end of the terminal block. Two hooks are fixedly connected to the top surface of the sliding seat. Both sides of the terminal block are fixedly connected to protrusions that slide into the inner sides of adjacent hooks. A toggle frame is fixedly connected to the top surface of the terminal block. The limiting frame restricts the position of the terminal block, while the hooks restrict the position of the terminal block through the protrusions, allowing the terminal block to be inserted into the sliding seat. The terminal block can be moved by the toggle frame, causing it to move out of the limiting frame and disengage the protrusions from the hooks. This allows the terminal block to be removed from the sliding seat. When a terminal block is damaged, the corresponding terminal block can be replaced without removing other wires or replacing the entire wiring structure, making replacement relatively simple. During wiring installation, wires can be connected to the terminal blocks from outside the enclosure, avoiding operation inside the narrow enclosure and facilitating wiring.
[0011] Furthermore, the sliding frame has connecting brackets fixedly connected to both sides of its top surface. Two connecting brackets are rotatably connected to limiting brackets that contact the sides of several terminal blocks. A positioning screw is screwed onto the top surface of each connecting bracket, contacting the side of the limiting bracket. The limiting bracket has several openings corresponding to the terminal blocks. Several organizing blocks are slidably connected to the top surface of each opening. The positioning screws can abut against the limiting brackets, which can block the terminal blocks, preventing them from sliding out of the sliding frame. The wires on the terminal blocks can pass between two corresponding organizing blocks, allowing the wires to be organized. The organizing blocks are slidably positioned within the openings to avoid obstructing the movement of the terminal blocks and wires. The positioning screws can be unscrewed, and the limiting brackets can be rotated upwards to separate from the terminal blocks, allowing the terminal blocks to be removed.
[0012] Furthermore, a T-shaped plate is fixedly connected to the inner side of the insertion slot and slidably connected to the conductive rod. A pushing block, slidably connected to the T-shaped plate, is fixedly connected to one end of the conductive rod located within the insertion slot. A return spring, fixedly connected to the side of the T-shaped plate, is fixedly connected to the side of the pushing block. A contact plate, slidably connected to the side of the T-shaped plate, is slidably connected to the top surface of the insertion slot, with adjacent contact plates in contact with each other. A rotating rod is rotatably connected to the inner side of the T-shaped plate. A rotating shaft is rotatably connected to the top of one end and the bottom of the other end of the rotating rod. The bottom surface of the contact plate and the top surface of the pushing block are slidably connected to the side of the adjacent rotating shaft. The rotating shaft will only move along the short side of the contact plate on the contact plate and the pushing block. Thus, when the rotating shaft moves, it can push the contact plate and the pushing block to move along the long side of the contact plate. The conductive rod and the contact plate can be connected to the rotating shaft via the rotating rod. When the contact plate moves, the pushing block and the conductive rod will move in opposite directions via the rotating rod and the rotating shaft.
[0013] When the ends of two corresponding terminals on different sliding frames are brought into contact, the abutment plates inside the two terminals will press against each other, causing the abutment plates to retract into the insertion slots. The abutment plates can then push the rotating rod to rotate via the rotating shaft. The rotating rod can then push the conductive rod to move out of the insertion slot, thus inserting it into the insertion slot of the adjacent terminal. This allows the conductive rods on the two adjacent terminals to be inserted and connected, and the two conductive rods conduct electricity to the corresponding terminals at their ends, thereby connecting the circuit. When the two sliding frames are moved away from each other, the two corresponding terminals on different sliding frames will separate, causing the conductive rods inside the two terminals to separate and the abutment plates inside the two terminals to move away from each other. At this time, under the action of the return spring, the pushing block can pull the conductive rod into the insertion slot. The pushing block will then cause the rotating rod to rotate in the opposite direction. The rotating rod can then move the abutment plates out of the insertion slots via the rotating shaft, thus disconnecting the two adjacent terminals. When the terminals are separated, the conductive rod can retract into the insertion slot, which helps to ensure safety.
[0014] The beneficial effects of this invention are: 1. Two sliding frames are slidably connected to the top surface of the mounting plate. Several wiring modules can be divided into two parts and set on the two sliding frames respectively, so that the wiring modules on the two sliding frames correspond one-to-one. The two corresponding wiring modules are connected by a conductive rod. Then the wires can be set on the terminal blocks. The temperature inside the box can be monitored by a temperature sensor. When the temperature at the connection point rises, the two sliding frames can be separated by an adjustment mechanism, thereby separating the two corresponding terminal blocks on different sliding frames, thus disconnecting the circuit, preventing the temperature from rising continuously and causing a fire inside the box, which helps to improve the safety factor. 2. Several X-shaped frames are provided on the inner side of the sliding frame. These X-shaped frames can form a telescopic frame. When two sliding frames move away from each other, the circular block will move along the limit rail. When the circular block passes the corner of the limit rail, it will move in the inclined direction, thereby moving the adjusting seats in the same sliding frame away from each other. This causes the telescopic frame composed of X-shaped frames to extend, thus moving the several terminal blocks on the sliding frame away from each other, thereby completely separating the terminal blocks, improving the safety factor. After separating the terminal blocks, it is easier to dissipate heat from the heated terminal blocks and prevent them from burning out. At the same time, the combination connection of the terminal blocks means that if one terminal block is damaged, the corresponding terminal block can be replaced without removing other wires and replacing the entire wiring structure. Replacement is relatively simple. When installing wiring, the wires can be connected to the terminal blocks from the outside of the box, avoiding operation inside the narrow box.

Detailed Implementation
[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0019] Please see Figure 1-14As shown, a wiring device for preventing burnout in a photovoltaic power generation system includes a housing 100, a cover plate 110 on the top surface of the housing 100, and an adjustment module 200 inside the housing 100. The adjustment module 200 includes a mounting plate 210, two sliding frames 230 in contact with each other are slidably connected to the top surface of the mounting plate 210, and a plurality of sliding seats 240 are slidably connected to the top surface of the sliding frames 230. A wiring module 300 is provided on the inner side of the sliding seats 240, and the wiring module 300 includes a terminal block 310. Two adjacent terminals located on different sliding frames 230 are connected to the terminal blocks. Each of the terminal blocks 310 has a plug-in slot 313 at one end that is close to each other, and a wiring hole is provided at the other end of the terminal block 310. A conductive block is embedded in the bottom surface of the plug-in slot 313. A conductive rod 320 that contacts the top surface of the conductive block is slidably connected to the inner side of the plug-in slot 313 of the adjacent terminal block. The conductive rod 320 is slidably plugged into the inner side of the plug-in slot 313 of the adjacent terminal block 310, and the two adjacent conductive rods 320 are in contact with each other. An adjustment mechanism 220 for adjusting the position of the sliding frame 230 is provided on the top surface of the mounting plate 210. A temperature sensor is provided inside the housing 100.
[0020] Several wiring modules 300 can be installed on both sliding frames 230, with each module corresponding to the previous one. Wires can be connected to the wiring holes on the terminal blocks 310. The wire ends are pressed into the corresponding wiring holes using clamping screws on the terminal blocks 310. The insertion slots 313 of the two terminal blocks 310 located on different sliding frames 230 correspond to each other, allowing the conductive rod 320 of one terminal block 310 to be inserted into the insertion slot 313 of the other terminal block 310, making contact between the conductive rod 320 and the conductive block within the insertion slot 313. The two adjacent conductive rods 320 are brought into contact with each other, thereby connecting the two corresponding terminals 310 through the mutual insertion of the conductive rods 320. The temperature inside the housing 100 can be monitored by a temperature sensor. If a problem occurs at the connection of the terminal 310 and the terminal 310 overheats, the two sliding frames 230 can be moved away from each other by the adjustment mechanism 220, thereby separating the terminal 310 on the two sliding frames 230, disconnecting the circuit, preventing the terminal 310 from burning out due to continuous temperature rise, and preventing a fire inside the housing 100. This helps to improve the safety factor.
[0021] The adjusting mechanism 220 includes two fixed frames 221 and two bidirectional lead screws 222. The bottom surface of the fixed frame 221 is fixedly connected to the long side of the top surface of the mounting plate 210. Both ends of the fixed frame 221 are rotatably connected to the sides of the two bidirectional lead screws 222. The sides of the bidirectional lead screws 222 are screwed together with two sliding blocks 223 that are slidably connected to the top surface of the mounting plate 210. Both ends of the sliding frame 230 are fixedly connected to the sides of the adjacent sliding blocks 223. One end of each of the two bidirectional lead screws 222 is located inside a fixed frame 221 and is fixedly fitted with a pulley. 224, and two pulleys 224 are connected by belt drive. One end of a two-way lead screw 222 is located inside another fixed frame 221 and is fixedly sleeved with a transmission gear 225. The bottom surface of the housing 100 is provided with an adjusting motor 130 corresponding to the transmission gear 225. The output end of the adjusting motor 130 is driven by a transmission shaft 131. The inner side of the mounting plate 210 is rotatably connected to the transmission shaft 131. The side of the connecting shaft 215 and the side of the transmission shaft 131 are both fixedly sleeved with connecting gears, and the two connecting gears mesh. In the transmission system, transmission gear 225 meshes with a connecting gear located at the top. When the temperature sensor detects an increase in the internal temperature of the housing 100, it can activate the regulating motor 130, causing the regulating motor 130 to drive the transmission shaft 131 to rotate. The transmission shaft 131 can drive the connecting shaft 215 to rotate via the connecting gear. The connecting shaft 215, in turn, drives a double-acting lead screw 222 to rotate via the connecting gear and transmission gear 225. One double-acting lead screw 222 can drive another double-acting lead screw 222 to rotate via pulley 224. When the lead screw 222 rotates, the two sliding blocks 223 on the same bidirectional lead screw 222 will move in opposite directions. The sliding blocks 223 can drive the sliding frame 230 to move, thereby causing the two sliding frames 230 to move in opposite directions, separating the two corresponding terminals 310 from each other, so that the conductive rod 320 in one terminal 310 is disengaged from the insertion slot 313 in the other terminal 310. Even if the conductive rods 320 of the two terminals 310 are disengaged from each other, the circuit is disconnected at the terminal 310 to prevent further heating and fire.
[0022] Several X-shaped frames 250 are provided on the inner side of the sliding frame 230 corresponding to the sliding seat 240, and the two ends of adjacent X-shaped frames 250 are rotatably connected. The top of the shaft of the X-shaped frame 250 is rotatably connected to a limiting block 251 that is slidably connected to the top inner side of the sliding frame 230, and the top surface of the limiting block 251 is fixedly connected to the bottom surface of the sliding seat 240. Several X-shaped frames 250 can form a telescopic frame. The limiting block 251 can restrict the position of the X-shaped frame 250 and can extend the telescopic frame. At this time, the limiting block 251 on the X-shaped frame 250 will be evenly separated. The limiting block 251 can drive the sliding seat 240 to move, thereby separating several sliding seats 240 and evenly separating several terminal blocks 310 on the same sliding frame 230. This is beneficial to improving the safety factor and at the same time, it is convenient to dissipate heat from the heated terminal blocks 310 and prevent the terminal blocks 310 from burning out.
[0023] The top surface of the mounting plate 210 has a mounting groove 211. Limit rails 212 are fixedly connected to the four corners of the inner side of the mounting groove 211. Adjusting seats 260 are slidably connected to both sides of the inner side of the sliding frame 230. The sides of the adjusting seats 260 are slidably connected to the ends of the adjacent X-shaped frame 250. A round block 261 is fixedly connected to the bottom of the adjusting seat 260 and slidably connected to the inner side of the adjacent limit rail 212. When the sliding frame 230 moves, it can drive the round block 261 to move along the limit rail 212. (The last sentence appears to be incomplete and possibly refers to a different topic.) After the conductive rods 320 separate from each other, the circular block 261 continues to move and will move to the corner of the limiting rail 212. The circular block 261 will continue to move obliquely along the inclined section of the limiting rail 212, so that the circular block 261 moves towards the end of the sliding frame 230. The circular block 261 can drive the end of the adjusting seat 260 to move, so that the two adjusting seats 260 in the sliding frame 230 move in opposite directions. At this time, the adjusting seat 260 can stretch the telescopic frame composed of several X-shaped frames 250, so that several terminal blocks 310 separate from each other.
[0024] Two partitions 213 are rotatably connected to the inner side of the mounting groove 211 corresponding to the sliding frame 230. A fixed shaft 214 is rotatably connected to the inner side of the partition 213 and fixedly connected to the inner side of the mounting groove 211. A torsion spring is provided between the side of the fixed shaft 214 and the inner side of the partition 213. When the two sliding frames 230 move in opposite directions and separate from the adjacent partition 213, the partition 213 can be rotated upward under the action of the torsion spring. In this way, the partition 213 can block between the two sliding frames 230 and block the corresponding terminal blocks 310 on the two sliding frames 230, further improving the safety factor.
[0025] A limiting frame 241 is fixedly connected to the top surface of the sliding seat 240, which is slidably inserted into one end of the terminal block 310. Two hooks 242 are fixedly connected to the top surface of the sliding seat 240. Each of the two sides of the terminal block 310 has a protrusion 312 that slidably connects to the inner side of the adjacent hook 242. A toggle frame 311 is fixedly connected to the top surface of the terminal block 310. The limiting frame 241 restricts the position of the terminal block 310, while the hooks 242 can restrict the position of the terminal block 310 through the protrusions 312, allowing the terminal block 310 to insert into the sliding seat 240. The toggle frame 311 moves the terminal block 310, causing it to move out of the limit frame 241 and disengage the protrusion 312 from the hook block 242. This allows the terminal block 310 to be removed from the sliding seat 240. If a terminal block 310 is damaged, the corresponding terminal block 310 can be replaced without removing other wires or replacing the entire wiring structure. The replacement is relatively simple. During installation and wiring, the wires can be connected to the terminal block 310 from outside the enclosure 100, avoiding operation inside the narrow enclosure 100 and facilitating wiring.
[0026] Connecting brackets 231 are fixedly connected to both sides of the top surface of the sliding frame 230. Limiting brackets 232 that rotatably connect to the sides of several terminal blocks 310 are rotatably connected to the sides of the two connecting brackets 231. Positioning screws 233 that screw onto the top surface of the connecting brackets 231 and contact the sides of the limiting brackets 232 are screwed onto the top surface of the connecting brackets 231. Several opening slots are opened on the limiting brackets 232 corresponding to the terminal blocks 310. Several organizing blocks are slidably connected to the top surface of the opening slots. The positioning screws 233 can abut against the limiting brackets 232. The limiting brackets 232 can block the terminal blocks 310 and prevent the terminal blocks 310 from sliding out of the sliding seat 240. The wires on the terminal blocks 310 can pass between the corresponding two organizing blocks. The organizing blocks organize the wires. At the same time, the organizing blocks are slidably set in the opening slots to avoid blocking the movement of the terminal blocks 310 and the wires. The positioning screws 233 can be unscrewed. At this time, the limiting brackets 232 can be rotated upward to separate the limiting brackets 232 from the terminal blocks 310. Then the terminal blocks 310 can be taken out.
[0027] A T-shaped plate 330, which is slidably connected to a conductive rod 320, is fixedly connected to the inner side of the insertion slot 313. A push block 321, which is slidably connected to the T-shaped plate 330, is fixedly connected to one end of the conductive rod 320 located in the insertion slot 313. A return spring 322, which is fixedly connected to the side of the T-shaped plate 330, is fixedly connected to the side of the push block 321. An abutment plate 340, which is slidably connected to the side of the T-shaped plate 330, is slidably connected to the top surface of the insertion slot 313, and two adjacent abutment plates 340 are in contact with each other. A rotating rod 350 is rotatably connected to the inner side of the T-shaped plate 330, and both the top of one end of the rotating rod 350 and the bottom of the other end rotate. A rotating shaft 351 is connected to the bottom surface of the abutment plate 340 and the top surface of the push block 321, which are slidably connected to the side of the adjacent rotating shaft 351. The rotating shaft 351 will only move along the short side of the abutment plate 340 on the abutment plate 340 and the push block 321. When the rotating shaft 351 moves, it can push the abutment plate 340 and the push block 321 to move along the long side of the abutment plate 340. The conductive rod 320 and the abutment plate 340 can be connected to the rotating shaft 351 through the rotating rod 350. When the abutment plate 340 moves, the push block 321 and the conductive rod 320 will move in opposite directions through the rotating rod 350 and the rotating shaft 351.
[0028] When the ends of two corresponding terminals 310 located on different sliding frames 230 come into contact with each other, the abutment plates 340 inside the two terminals 310 will press against each other, causing the abutment plates 340 to retract into the insertion slots 313. The abutment plates 340 can push the rotating rod 350 to rotate via the rotating shaft 351. The rotating rod 350 can push the conductive rod 320 to move out of the insertion slots 313 via the rotating shaft 351, thereby inserting it into the insertion slots 313 of the adjacent terminals 310. This causes the conductive rods 320 on the two adjacent terminals 310 to be inserted and connected to each other. The two conductive rods 320 conduct electricity to the two terminals 310 at their corresponding ends, thereby connecting the circuit. When the terminals move away from each other, the two corresponding terminals 310 located on different sliding frames 230 will separate from each other, causing the conductive rods 320 inside the two terminals 310 to separate from each other, and causing the abutment plates 340 inside the two terminals 310 to move away from each other. At this time, under the action of the return spring 322, the push block 321 can pull the conductive rod 320 into the insertion slot 313. At this time, the push block 321 will cause the rotating rod 350 to rotate in the opposite direction. The rotating rod 350 can move the abutment plate 340 out of the insertion slot 313 through the rotating shaft 351, thereby disconnecting the two adjacent terminals 310. When the terminals 310 are separated, the conductive rods 320 can be retracted into the insertion slot 313, which helps to ensure safety.
[0029] Working principle: In use, connect the wire to the wiring hole on the terminal block 310, insert the terminal block 310 into the sliding seat 240, insert the protrusion 312 into the hook block 242, and insert the terminal block 310 into the limiting frame 241. At this time, the ends of the two corresponding terminal blocks 310 on different sliding frames 230 will abut against each other, causing the abutment plates 340 in the two terminal blocks 310 to press against each other, so that the abutment plates 340 are retracted into the insertion groove 313. At this time, the abutment plates 340 can rotate the rotating rod 350 through the rotating shaft 351, and the rotating rod 350 can move the conductive rod 320 into the insertion groove 313 through the rotating shaft 351. 13. Move externally to insert into the insertion slot 313 in the adjacent terminal block 310, so that the conductive rods 320 on the two adjacent terminal blocks 310 are inserted into each other and connected, so that the two terminal blocks 310 at the two ends are connected through the two conductive rods 320, thereby connecting the circuit. Then, the limiting frame 232 can be rotated downward and the positioning screw 233 can be rotated to move downward and abut against the limiting frame 232. The limiting frame 232 can restrict the position of the terminal block 310 and prevent the terminal block 310 from coming out of the sliding seat 240. The wires on the terminal block 310 can pass through the corresponding organizing blocks on the limiting frame 232. During the circuit operation, the internal temperature of the enclosure 100 can be monitored by a temperature sensor. If the terminal block 310 overheats abnormally, causing the internal temperature of the enclosure 100 to rise, the regulating motor 130 can be started. The regulating motor 130 can drive the transmission shaft 131 to rotate. The transmission shaft 131 can drive the connecting shaft 215 to rotate via a connecting gear. The connecting shaft 215 can drive a double-acting lead screw 222 to rotate via the connecting gear and the transmission gear 225. The two double-acting lead screws 222 can rotate synchronously via the pulley 224. When the double-acting lead screws 222 rotate, the two sliding blocks 223 on them can move in opposite directions. The sliding blocks 223 can drive the sliding frame 230 to move, thereby... The two sliding frames 230 are moved in opposite directions. At this time, the two corresponding terminals 310 on different sliding frames 230 will separate from each other, causing the conductive rod 320 in one terminal 310 to separate from the insertion slot 313 in the adjacent terminal 310, and causing the two adjacent abutment plates 340 to move away from each other. At this time, under the action of the return spring 322, the conductive rod 320 can be retracted into the insertion slot 313, causing the rotating rod 350 to rotate in the opposite direction. The rotating rod 350 can move the abutment plate 340 to the outside of the insertion slot 313 through the rotating shaft 351, thereby disconnecting the two adjacent terminals 310 and disconnecting the circuit at the terminal 310 to prevent further heating and fire. When the sliding frame 230 moves, the round block 261 at the bottom of the adjusting seat 260 can move along the limiting rail 212. After the conductive rod 320 in one terminal block 310 separates from the insertion slot 313 in the adjacent terminal block 310, the round block 261 continues to move and will move to the corner of the limiting rail 212. Then the round block 261 will move obliquely along the limiting rail 212. The round block 261 can drive the adjusting seat 260 to move towards the end of the sliding frame 230, so that the two adjusting seats 260 in the sliding frame 230 move in opposite directions. Since the adjusting seat 260 is slidably connected to the end of the adjacent X-shaped frame 250, the adjusting seat 260 can stretch the telescopic frame composed of several X-shaped frames 250. The X-shaped frame 250 can drive the sliding seat 240 at its top to move through the limiting block 251, so that several terminal blocks 310 on the sliding frame 230 are separated from each other, preventing the terminal blocks 310 from burning out.
