Description

Technical Field

[0001] This invention relates to the field of busbar trunking connector technology, specifically to an intelligent busbar trunking connector with heat protection function. Background Technology

[0002] With the rapid development of industrial automation, informatization, and new energy fields, higher requirements are being placed on the reliability, safety, and intelligence of power distribution systems. As a crucial component for high-current transmission and distribution, busbar trunking plays a vital role in modern power distribution systems, undertaking the task of efficient, compact, and modular power transmission.

[0003] However, traditional busbar trunking and its connectors exhibit significant heat generation and heat accumulation issues under high load, long-term operation, and high ambient temperature conditions. During high-current operation, the pins and contact points are prone to significant heat generation, leading to degradation of contact materials, increased contact resistance, and consequently, accelerated temperature rise, thermal drift, and even localized overheating. This reduces the reliability and safety of the entire busbar trunking system. Furthermore, the intelligent monitoring and adaptive capabilities within the busbar trunking are insufficient. Traditional pins lack the ability to monitor and adaptively control key parameters such as temperature, current, and contact status in real time, making it difficult to provide early warnings and automatically coordinate power distribution under abnormal operating conditions. This increases the difficulty of operation and maintenance and the risk of downtime. To address these issues, this invention proposes an intelligent busbar trunking pin with anti-heat generation function. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent busbar connector with heat protection function to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A smart busbar connector with heat protection function includes a housing, an indicator light, and a wireless infrared sensor. The housing has a connection module inside, a protective module on one side of the connection module, and a wireless infrared sensor installed inside the connection module. The housing has an indicator light on the top, and the indicator light is electrically connected to the connection module and the wireless infrared sensor respectively. The connection module is used to connect to the plug of the plug box, the protection module is used to protect the working environment inside the housing, and the indicator light is used in conjunction with the connection module and the wireless infrared sensor to monitor the temperature inside the housing.

[0006] The connection module includes a connection block connected to the inner wall of the housing. A connecting strip is provided on one side of the connection block, and a bending baffle is connected to the end of the connecting strip. A positioning strip is arranged parallel to one side of the connecting strip, and a protective strip is provided on one side of the bending baffle. A pressure relief hole is horizontally formed inside the connection block. The connecting strip and the bending baffle on the connection block form a Z-shaped structure. One side of the connection block is fixedly connected to the connecting strip by bolts. The Z-shaped structure formed by the connecting strip and the bending baffle, together with the connecting strip, forms a bending clamping structure. The connecting strip is clamped to the plug of the connector box by one side. The pressure relief hole is used to balance the pressure between the inner wall and the outside of the housing when the plug is inserted.

[0007] The connecting block is trapezoidal. One side of the positioning strip engages with the connecting block, and another side of the positioning strip abuts against the inner connecting strip. One side of the protective strip is movably connected to the protective module. Two positioning strips are provided, symmetrically distributed about both sides of the connecting block. After the plug of the connector box is inserted into one side of the connecting strip, the inclined surface of the bent baffle guides the insertion direction of the plug. Simultaneously, the bent baffle causes the connecting strip to bend outwards. The positioning strip and the protective strip abut against both ends of the connecting strip, ensuring a tight fit between one side of the connecting strip and the plug. This improves the power transmission efficiency between the plug and the connecting strip, reduces resistance, and minimizes power loss.

[0008] The protective module includes a movable locking block, one side of which is fixedly connected to a protective strip. A spring is provided at the bottom of the movable locking block, and a positioning strip is fixedly connected to one side of the movable locking block. A movable rotating rod is movably connected to one side of the positioning strip. When the plug of the connector box is inserted into one side of the connecting strip, the plug abuts against a bending baffle. The bending baffle presses against the protective strip on one side, pushing the protective strip and causing the movable locking block to move horizontally. At the same time, the movable locking block moves the positioning strip. The movable rotating rod on the positioning strip moves along one side of the connecting strip. The surface of the movable rotating rod is roughened. The movable rotating rod rubs and cleans the side of the connecting strip that is connected to the plug, preventing oxidation of the connecting strip surface from affecting power transmission, improving self-cleaning ability, and avoiding safety hazards caused by internal oxidation and foreign objects.

[0009] One side of the protective strip is engaged with a hinge plate, and one side of the hinge plate is movably connected to a dust baffle. One side of the dust baffle is movably connected to the housing. When the plug of the connector box comes into contact with the bending baffle, the bending baffle pushes the protective strip on one side to deflect. The protective strip simultaneously drives the hinge plate to deflect, and the hinge plate simultaneously drives the dust baffle on one side to deflect. One side of the dust baffle is movably connected to the inner wall of the housing, causing the protective strip to drive the dust baffle to deflect inward, preventing dust from entering the housing and causing pollution, thus improving the durability of the device.

[0010] The bottom of the movable locking block is movably connected to the housing via a groove. One end of the spring is connected to one side of the movable locking block, and the other side of the spring is engaged with the inner wall of the housing via a groove. The movable locking block moves as the protective strip deflects. After the plug is fully inserted into the housing, the spring's reaction force pushes the protective strip on one side of the movable locking block. The V-shaped structure of the protective strip clamps and fixes the connecting strip and the plug, improving the stability of the connection. When the plug is pulled out, pressing the dustproof baffle inward pushes the protective strip away from the connecting strip, facilitating the quick removal of the plug.

[0011] The positioning strip has a groove, and the positioning strip is movably connected to one end of the movable rotating rod through the groove. The outer wall of the movable rotating rod is in contact with one side of the connecting strip. The groove on the positioning strip allows the movable rotating rod to move horizontally along the groove. A spring is provided on the inner wall of the groove, and the two ends of the spring are respectively engaged with two movable rotating rods symmetrically arranged in the groove, so that the movable rotating rod can quickly fit and rotate with one side of the connecting strip, improving the fit between the movable rotating rod and the connecting strip.

[0012] Compared with the prior art, the beneficial effects achieved by the present invention are: This invention improves the fit between the connecting strip and the plug box plug by setting a connection module, while improving the power transmission efficiency between the plug and the connecting strip, reducing the resistance at the connection point, reducing the loss of power during internal current transmission, and avoiding abnormal contact that increases the resistance value of power transmission and causes internal heat generation. The positioning strip and the protective strip abut against the two ends of the connecting strip to ensure a tight connection between the connecting strip and the plug, preventing gaps from being affected in high humidity environments, and improving the safety of the connection between the plug and the connecting strip. The elasticity of the positioning strip and the protective strip can provide elastic buffering under vibration. By setting up the protective module, the plug is inserted into the housing and bends the bending baffle. The bending baffle pushes the protective strip and moves the movable locking block horizontally. This causes the movable rotating rod on the positioning plate to rub and clean one side of the connecting strip, quickly self-cleaning one side of the connecting strip and removing the oxide surface. At the same time, it allows the connecting strip to quickly fit with the plug, further improving the efficiency and safety of power transmission. By connecting the module and the protective module, pressing the dustproof baffle inside the housing pushes the protective strip away from the connecting strip, making it easy for the user to quickly remove the plug and also facilitating user inspection and maintenance.

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Please see Figures 1-5 The present invention provides the following technical solution: A smart busbar connector with heat protection function includes a housing 1, an indicator light 4 and a wireless infrared sensor 5. The housing 1 has a connection module 2 inside, a protective module 3 on one side of the connection module 2, and the wireless infrared sensor 5 installed inside the connection module 2. The housing 1 has an indicator light 4 on the top, and the indicator light 4 is electrically connected to the connection module 2 and the wireless infrared sensor 5 respectively. The connection module 2 is used to connect to the plug of the plug box, the protection module 3 is used to protect the working environment inside the housing 1, and the indicator light 4 is used to monitor the internal temperature of the housing 1 in conjunction with the connection module 2 and the wireless infrared sensor 5.

[0017] The connecting module 2 includes a connecting block 201, which is connected to the inner wall of the housing. A connecting strip 202 is provided on one side of the connecting block 201, and a bending baffle 203 is connected to the end of the connecting strip 202. A positioning strip 204 is arranged parallel to one side of the connecting strip 202, and a protective strip 205 is provided on one side of the bending baffle 203. A pressure relief hole 206 is horizontally opened inside the connecting block 201. The connecting strip 202 and the bending baffle 203 on the connecting block 201 form a Z-shaped structure. One side of the connecting block 201 is fixedly connected to the connecting strip 202 by bolts. The Z-shaped structure formed by the connecting strip 202 and the bending baffle 203, together with the connecting strip 202, forms a bending clamping structure. One side of the connecting strip 202 is clamped to the plug of the connector box. The pressure relief hole 206 is used to balance the pressure between the inner wall and the outside of the housing 1 when the plug is inserted.

[0018] The connecting block 201 is trapezoidal. One side of the positioning strip 204 engages with the connecting block 201, and another side of the positioning strip 204 abuts against the inner connecting strip 202. One side of the protective strip 205 is movably connected to the protective module 3. Two positioning strips 204 are provided, symmetrically distributed about both sides of the connecting block 201. After the plug of the connector box is inserted into one side of the connecting strip 202, the inclined surface of the bent baffle 203 guides the insertion direction of the plug. Simultaneously, the bent baffle 203 causes the connecting strip 202 to bend outwards. The positioning strip 204 and the protective strip 205 abut against both ends of the connecting strip 202, ensuring a tight fit between one side of the connecting strip 202 and the plug. This improves the power transmission efficiency between the plug and the connecting strip 202, reduces resistance, and minimizes power loss.

[0019] The protective module 3 includes a movable latch 301. One side of the movable latch 301 is fixedly connected to the protective strip 205. A spring 302 is provided at the bottom of the movable latch 301. A positioning strip 303 is fixedly connected to one side of the movable latch 301. A movable rotating rod 304 is movably connected to one side of the positioning strip 303. When the plug of the connector box is inserted into one side of the connecting strip 202, the plug abuts against the bending baffle 203. The bending baffle 203 presses against the protective strip 205 on one side, pushing the protective strip 205 to move the movable locking block 301 horizontally. The movable locking block 301 simultaneously moves the positioning plate 303. The movable rotating rod 304 set on the positioning plate 303 moves along one side of the connecting strip 202. The surface of the movable rotating rod 304 is set to a rough surface. The movable rotating rod 304 rubs and cleans the side of the connecting strip 202 that is connected to the plug, avoiding oxidation of the surface of the connecting strip 202 from affecting power transmission, improving self-cleaning ability, and avoiding safety hazards caused by internal oxidation and foreign objects blocking the connection.

[0020] A hinge plate 305 is snapped onto one side of the protective strip 205. A dustproof baffle 306 is movably connected to one side of the hinge plate 305, and one side of the dustproof baffle 306 is movably connected to the housing 1. When the plug of the connector box abuts against the bending baffle 203, the bending baffle 203 pushes the protective strip 205 on one side to deflect. The protective strip 205 simultaneously drives the hinge plate 305 to deflect, and the hinge plate 305 simultaneously drives the dustproof baffle 306 on one side to deflect. One side of the dustproof baffle 306 is movably connected to the inner wall of the housing 1, so that the protective strip 205 drives the dustproof baffle 306 to deflect inward, preventing dust from entering the housing 1 and causing pollution, thus improving the durability of the device.

[0021] The bottom of the movable locking block 301 is movably connected to the housing 1 via a groove. One end of the spring 302 is connected to one side of the movable locking block 301, and the other side of the spring 302 is engaged with the inner wall of the housing 1 via a groove. The movable locking block 301 moves as the protective strip 205 deflects. After the plug is fully inserted into the housing 1, the reaction force of the spring 302 pushes the protective strip 205 on one side of the movable locking block 301. The V-shaped structure of the protective strip 205 clamps and fixes the connecting strip 202 and the plug, improving the stability of the insertion. When the plug is pulled out, pressing the dustproof baffle 306 inward pushes the protective strip 205 away from the side of the connecting strip 202, facilitating the quick removal of the plug.

[0022] The positioning strip 303 has a sliding groove, which is movably connected to one end of the movable rotating rod 304. The outer wall of the movable rotating rod 304 is in contact with one side of the connecting strip 202. The sliding groove on the positioning strip 303 allows the movable rotating rod 304 to move horizontally along the groove. A spring is provided on the inner wall of the groove, and the two ends of the spring are respectively engaged with two symmetrically arranged movable rotating rods 304 in the groove, so that the movable rotating rod 304 can quickly fit and rotate with one side of the connecting strip 202, improving the fit between the movable rotating rod 304 and the connecting strip 202.

[0023] Working principle of the invention: First, insert the plug of the plug box into the connection module 2 along one side of the housing 1 for connection. The connecting strip 202 and the bending baffle 203 on the connecting block 201 form a Z-shaped structure. One side of the connecting block 201 is fixedly connected to the connecting strip 202 by bolts. The Z-shaped structure formed by the connecting strip 202 and the bending baffle 203, together with the connecting strip 202, forms a bending clamping structure. The connecting strip 202 is clamped tightly to the plug of the plug box by one side. The pressure relief hole 206 is used to balance the pressure between the inner wall and the outside of the housing 1 when the plug is inserted. There are two positioning strips 204, which are symmetrically distributed about both sides of the connecting block 201. After the plug of the plug box is inserted into one side of the connecting strip 202, the inclined surface of the bent baffle 203 guides the insertion direction of the plug. At the same time, the bent baffle 203 causes the connecting strip 202 to bend outward. The positioning strips 204 and the protective strips 205 abut against the two ends of the connecting strip 202, ensuring that one side of the connecting strip 202 is tightly fitted with the plug, improving the power transmission efficiency between the plug and the connecting strip 202, reducing resistance, and reducing power loss. When the plug of the connector box is inserted into one side of the connecting strip 202, the plug abuts against the bending baffle 203. The bending baffle 203 presses against the protective strip 205 on one side, pushing the protective strip 205 to drive the movable block 301 to move horizontally. The movable block 301 also drives the positioning strip 303 to move. The movable rotating rod 304 set on the positioning strip 303 moves along one side of the connecting strip 202. By setting the sliding groove on the positioning strip 303, the movable rotating rod 304 can move horizontally along the sliding groove. A spring is set on the inner wall of the sliding groove, and the two ends of the spring are respectively engaged with two movable rotating rods 304 symmetrically arranged in the sliding groove, so that the movable rotating rod 304 can quickly fit and rotate with one side of the connecting strip 202, thereby improving the fit between the movable rotating rod 304 and the connecting strip 202. The surface of the movable rotating rod 304 is set to a rough surface. The side of the connecting strip 202 that is connected to the plug is cleaned by friction using the movable rotating rod 304, so as to avoid oxidation of the surface of the connecting strip 202 from affecting power transmission and to avoid safety hazards caused by internal oxidation and foreign objects blocking the plug. When the plug of the connector box comes into contact with the bending baffle 203, the bending baffle 203 pushes the protective strip 205 on one side to deflect. The protective strip 205 simultaneously drives the hinge plate 305 to deflect, and the hinge plate 305 simultaneously drives the dustproof baffle 306 on one side to deflect. One side of the dustproof baffle 306 is movably connected to the inner wall of the housing 1, so that the protective strip 205 drives the dustproof baffle 306 to deflect inward, preventing dust from entering the housing 1 and causing pollution, thus improving the durability of the device. The movable locking block 301 moves along with the deflection of the protective strip 205. After the plug is fully inserted into the housing 1, the protective strip 205 on one side of the movable locking block 301 is pushed by the reaction force of the spring 302. The V-shaped structure of the protective strip 205 clamps and fixes the connecting strip 202 and the plug, improving the stability of the insertion. When the plug is pulled out, the dust baffle 306 is pressed inward to push the protective strip 205 away from the side of the connecting strip 202, making it easy to quickly remove the plug. Inside the housing 1, a wireless infrared sensor 5 is positioned directly opposite the plug between the two connecting strips 202 to monitor the temperature of the plug in real time. The internal temperature and operating status are displayed via an indicator light 4.
