Description

Technical Field

[0001] This invention relates to the field of busbar connection technology, specifically a dedicated busbar connector for connecting busbar trunking. Background Technology

[0002] Busbar trunking is a closed metal device made of copper or aluminum busbar columns, used to distribute a large amount of power to various components of a distributed system. The connection units set on the busbar trunking are usually connected by plug-in connection. During operation, multiple conductive bars on two mounting frames are aligned one to one to determine the position between the two mounting frames. Then, multiple insulating clamps are inserted between multiple sensing rods. Using multiple through holes on the insulating clamps and two insulating through bolts, the multiple conductive bars and multiple insulating clamps are fastened together, thereby completing the plug-in connection of the connection units on the two mounting frames.

[0003] However, in the use of traditional busbar connectors, the lack of pressure on both sides after the connector center is tightened can easily cause the connector ends to be loosely clamped, resulting in electric arcing. Furthermore, the lack of locking measures after tightening the connector can easily cause the bolts to loosen. When the busbar is inserted into the connector, the multiple insulating plates on the connector are loose and can rotate freely. The connection requires alignment and a certain gap to be made in the connector to facilitate the insertion of the busbar, which is cumbersome and reduces the connection efficiency. At the same time, the lack of anti-collision protection measures on the side walls when the connector is connected to the busbar can easily cause the busbar to shift after insertion, affecting the normal power transmission. Summary of the Invention

[0004] To address the problems in the prior art, the present invention provides a dedicated bus connector for connecting busbar trunking.

[0005] The technical solution adopted by this invention to solve its technical problem is: a special bus connector for connecting busbar trunking, comprising:

[0006] Insulating board;

[0007] A clamping mechanism is installed on the insulating plate. The clamping mechanism includes a conductive plate. Conductive plates are installed on both sides of the multiple insulating plates. A through hole is provided at the center of the multiple insulating plates. The two outermost insulating plates have no conductive plates installed on their outer sides. Four vertically distributed pressure blocks are fixedly connected to the outer sides of the two outermost insulating plates. The pressure blocks have a trapezoidal structure. A screw is slidably connected to the center of the multiple insulating plates. A nut is threaded to one end of the screw. The multiple insulating plates are fitted together end to end by the cooperation of the screw and the nut.

[0008] An abutting mechanism is installed on the clamping mechanism.

[0009] Specifically, one end of the screw is provided with a drive groove, which is a hexagonal structure, and multiple conductive plates are provided with multiple equally spaced grooves.

[0010] Specifically, the clamping mechanism is equipped with a fastening mechanism, which includes a connecting seat. One end of the screw is rotatably connected to the connecting seat, which has a frustum-shaped structure. The four sets of pressure blocks are provided with multiple annularly distributed limiting grooves on their outer sides. The connecting seat and the nut are respectively vertically fixed with multiple annularly distributed limiting blocks, which engage with the inside of the limiting grooves.

[0011] Specifically, the contact mechanism includes a fixing block, with a fixing block fixedly connected to the center of a plurality of insulating plates. The fixing block extends to the outside of the conductive plate at both ends. The fixing block has a frame-shaped structure. A guide groove is provided at each of the four corners on one side of the fixing block, and a guide rod is provided at each of the four corners on the other side of the fixing block. The guide rod is slidably connected to the inside of the guide groove.

[0012] Specifically, a rubber ring and a telescopic spring are respectively installed on both sides of the fixing block, with the telescopic spring located inside the rubber ring.

[0013] Specifically, the clamping mechanism is equipped with a positioning mechanism, which includes baffles. Two sets of baffles are slidably connected to the edges of the multiple insulating plates on both sides. Multiple mounting seats are fixedly connected to the opposite sides of the two sets of baffles. Multiple columns are fixedly connected to the outer edges of the two sides of the fixing block. A sliding rod is installed inside the multiple columns. The sliding rod is slidably connected to the inside of the column through a movable spring. One end of the sliding rod extends to the outside of the column and is fixedly connected to the mounting seat.

[0014] Specifically, the clamping mechanism is equipped with a protective mechanism, which includes a helical rack. The helical rack is installed inside the connecting seat and has a circular structure. A sliding plate is slidably connected to the inner side of the top of the screw. The sliding plate is slidably connected to the inside of the screw through multiple compression springs. Both ends of the sliding plate extend to the bottom of the helical rack. A locking block is fixedly connected to both ends of the sliding plate. The top of the locking block has a toothed structure, and the sharp teeth on the top of the locking block are opposite in direction to the sharp teeth of the helical rack. The top of the locking block abuts against the helical rack. A pressure rod is installed at the center of the top of the sliding plate. The top of the pressure rod extends into the drive groove and is slidably connected to the screw.

[0015] Specifically, the bottom of the skateboard is vertically connected to multiple movable rods, which are slidably connected through multiple compression springs and screws. The pressure rods are hexagonal prism structures.

[0031] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0032] like Figures 1-8 As shown, the present invention provides a special bus connector for connecting busbar trunking, comprising an insulating plate 1, a clamping mechanism 2 mounted on the insulating plate 1, an abutting mechanism 3 mounted on the clamping mechanism 2, a positioning mechanism 4 mounted on the clamping mechanism 2, a fastening mechanism 5 mounted on the clamping mechanism 2, and a protective mechanism 6 mounted on the clamping mechanism 2.

[0033] Specifically, the clamping mechanism 2 includes a conductive plate 201. Conductive plates 201 are respectively installed on both sides of the plurality of insulating plates 1. A through hole 206 is provided at the center of each of the plurality of insulating plates 1. No conductive plate 201 is installed on the outer sides of the two outermost insulating plates 1. Four vertically distributed pressure blocks 202 are fixedly connected to the outer sides of the two outermost insulating plates 1. The pressure blocks 202 have a trapezoidal structure. A screw 203 is slidably connected to the center of each of the plurality of insulating plates 1. A nut 204 is threaded to one end of each screw 203. The plurality of insulating plates 1 are mutually fitted end-to-end through the cooperation of the screw 203 and the nut 204. The action of the plurality of insulating plates 1 facilitates the installation of the plurality of conductive plates 201. The device connects two pairs of busbars by clamping the busbars with multiple insulating plates 1. Under the action of the conductive plate 201, the two pairs of connected busbars conduct electricity. The cooperation of the screw 203 and the nut 204 facilitates the clamping of the multiple insulating plates 1, ensuring that the multiple insulating plates 1 clamp the busbars tightly and will not loosen, enabling the busbars to better transmit power. Four pressure blocks 202 are installed on the outer side of two of the insulating plates 1. The pressure blocks 202 have a trapezoidal structure, which helps to spread the push of the screw 203 to the four sides of the insulating plate 1, making the insulating plate 1 clamp the busbars tightly and preventing the ends of the insulating plate 1 from warping or loosening.

[0034] Specifically, one end of the screw 203 is provided with a drive groove 207, which is a hexagonal structure. Multiple conductive plates 201 are provided with multiple equally spaced grooves 205. Under the action of the drive groove 207, it is convenient to drive and control the screw 203 with a hex wrench, making the operation more convenient and safer, reducing wear on the screw 203. Under the action of the multiple grooves 205, it is convenient to store the applied conductive paste and prevent the busbar from slipping and loosening on the conductive plate 201.

[0035] Specifically, the fastening mechanism 5 includes a connecting seat 503, one end of which is rotatably connected to the screw 203. The connecting seat 503 has a frustum-shaped structure. Multiple annularly distributed limiting grooves 502 are provided on the outer sides of the four sets of pressure blocks 202. Multiple annularly distributed limiting blocks 501 are vertically fixed to one side of the connecting seat 503 and the nut 204, respectively. The limiting blocks 501 engage with the limiting grooves 502. The fastening mechanism 5 is achieved through the connection between the connecting seat 503 and the screw 203. The rotating connection prevents the screw 203 from directly rotating and wearing against the pressure block 202, instead allowing it to rotate with the connecting seat 503. The connecting seat 503 then abuts against the pressure block 202, making the rotation of the screw 203 easier. Simultaneously, the engagement of the limiting block 501 and the limiting groove 502 prevents the nut 204 and the connecting seat 503 from rotating due to contact with the pressure block 202, thus ensuring a more stable fastening of the screw 203 to the insulating plate 1.

[0036] Specifically, the contact mechanism 3 includes a fixing block 301. A fixing block 301 is fixedly connected to the center of each of the multiple insulating plates 1. Both ends of the fixing block 301 extend to the outside of the conductive plate 201. The fixing block 301 has a frame-shaped structure. Guide grooves 302 are provided at the four corners of one side of the fixing block 301, and guide rods 305 are provided at the four corners of the other side of the fixing block 301. The guide rods 305 are slidably connected to the guide grooves 302. The action of the multiple fixing blocks 301 facilitates installation with the multiple insulating plates 1, allowing the two mating busbars to contact each other and preventing the busbars from contacting the screw 203, thus providing excellent insulation protection. When the multiple insulating plates 1 clamp the busbars, the guide rods 305 on the fixing block 301 move in and out of the guide grooves 302, preventing the multiple insulating plates 1 from swinging and providing positioning.

[0037] Specifically, rubber rings 304 and telescopic springs 303 are respectively installed on both sides of the fixing block 301. The telescopic springs 303 are located inside the rubber rings 304. The rubber rings 304 help to shield and protect the telescopic springs 303. After being clamped by multiple insulating plates 1, the two rubber rings 304 abut against each other, thereby shielding and wrapping the telescopic springs 303. Under the action of the telescopic springs 303, the insulating plates 1 can be opened when not clamped, maintaining a certain distance, which facilitates the insertion and connection of the busbar. The operation is more convenient, and there is no need to push open the insulating plates 1 to insert the busbar when connecting the busbar.

[0038] Specifically, the positioning mechanism 4 includes baffles 401. Two sets of baffles 401 are slidably connected to the edges of the multiple insulating plates 1. Multiple mounting seats 403 are fixedly connected to the opposite sides of the two sets of baffles 401. Multiple columns 402 are fixedly connected to the outer edges of the two sides of the fixing block 301. A sliding rod 404 is installed inside the multiple columns 402. The sliding rod 404 is slidably connected to the inside of the column 402 through a movable spring 405. One end of the sliding rod 404 extends to the outside of the column 402 and is fixedly connected to the mounting seat 403. Under the action of the mounting base 403, it is beneficial to connect and support the baffle 401 with the outside of the fixing block 301. Under the action of the movable spring 405, the baffle 401 and the conductive plate 201 on the outside of the insulating plate 1 can slide. Through the two sets of symmetrical baffles 401, it is beneficial to clamp and abut the busbar to be connected, so that the busbar can be kept horizontal and the conductive plate 201 can fit with the busbar with the maximum area. Since the baffle 401 and the conductive plate 201 can slide, it is convenient to clamp and abut the busbar of different widths.

[0039] Specifically, the protective mechanism 6 includes a helical rack 606, which is installed inside the connecting seat 503. The helical rack 606 has a circular structure. A sliding plate 602 is slidably connected to the inner top of the screw 203. The sliding plate 602 is slidably connected to the inside of the screw 203 through multiple compression springs 604. Both ends of the sliding plate 602 extend to the bottom of the helical rack 606. A locking block 605 is fixedly connected to both ends of the sliding plate 602. The top of the locking block 605 has a toothed structure, and the pointed teeth on the top of the locking block 605 are opposite in direction to the pointed teeth of the helical rack 606. The top of the locking block 605 abuts against the helical rack 606. A pressure rod 601 is installed at the center of the top of the sliding plate 602. The top of the pressure rod 601 extends into the drive groove 207 and is slidably connected to the screw 203. The compression spring 604 facilitates the contact of the slide plate 602, causing the slide plate 602 to drive the locking block 605 to contact the helical rack 606. Since the sharp teeth on the locking block 605 are in the opposite direction to the sharp teeth on the helical rack 606, after the locking block 605 contacts the helical rack 606, the screw 203 will not rotate in the opposite direction, thus ensuring that the screw 203 clamps and fixes the insulating plate 1 tightly. When the drive groove 207 is driven by a hex wrench, the wrench contacts and squeezes the pressure rod 601. The pressure rod 601 causes the slide plate 602 to slide away from the compression spring 604, and the locking block 605 separates from the helical rack 606, allowing the screw 203 to rotate freely, realizing the tightening and loosening work, and effectively protecting the screw 203.

[0040] Specifically, the bottom of the slide plate 602 is vertically connected to multiple movable rods 603. The multiple movable rods 603 are slidably connected through multiple compression springs 604 and screws 203. The pressure rod 601 has a hexagonal prism structure. Under the action of the movable rods 603, it helps to guide the slide plate 602, making the slide plate 602 slide smoothly and stably without deviation. At the same time, it makes the pressure rod 601 slide smoothly without free rotation, thus improving drive control.

[0041] In use, this invention first facilitates the installation of multiple conductive plates 201 through the action of multiple insulating plates 1. The multiple insulating plates 1 clamp the busbars, thereby connecting two pairs of busbars. The conductive plates 201 enable the two connected busbars to conduct electricity. The cooperation of screws 203 and nuts 204 further secures the multiple insulating plates 1, ensuring a tight and secure grip on the busbars, allowing for better power transmission. Four pressure blocks 202 are installed on the outer sides of two insulating plates 1. These pressure blocks 202 have a trapezoidal structure, which helps to distribute the push of the screws 203 to the four sides of the insulating plates 1, ensuring a tight grip on the busbars and preventing the ends of the insulating plates 1 from warping or loosening. The drive groove 207 facilitates the control of the screw 203 via a hex wrench, making operation more convenient and safer, and reducing wear on the screw 203. Multiple grooves 205 facilitate the storage of applied conductive paste and prevent the busbar from slipping or loosening on the conductive plate 201. The rotating connection between the connecting seat 503 and the screw 203 prevents the screw 203 from directly rotating and wearing against the pressure block 202, instead allowing it to rotate with the connecting seat 503, which then abuts against the pressure block 202, making the screw 203 rotate with less effort. Simultaneously, the engagement of the limiting block 501 and the limiting groove 502 prevents the nut 204 and the connecting seat 503 from rotating against the pressure block 202, thus preventing the screw 203 from rotating. The multiple fixing blocks 301 ensure a more stable fastening of the insulating plate 1, facilitating its installation and allowing the two mating busbars to contact each other. This prevents the busbars from contacting the screw 203, providing excellent insulation protection. When the busbars are clamped by the multiple insulating plates 1, the guide rods 305 and guide grooves 302 on the fixing blocks 301 move in and out, preventing the insulating plates 1 from swinging and providing positioning. The rubber rings 304 effectively shield and protect the telescopic spring 303. After being clamped by the multiple insulating plates 1, the two rubber rings 304 abut against each other, thus shielding and wrapping the telescopic spring 303. The telescopic spring 303 also allows the insulating plates 1 to be opened when not clamped. Maintaining a certain distance facilitates busbar insertion and connection, making operation more convenient. It eliminates the need to push open the insulation plate 1 to insert the busbar during connection. The mounting bases 403 on the column 402 facilitate connection and support between the baffle 401 and the outer side of the fixing block 301. Furthermore, the movable spring 405 allows the baffle 401 and the conductive plate 201 on the outer side of the insulation plate 1 to slide. The two sets of symmetrical baffles 401 effectively clamp and abut the busbar to be connected, keeping the busbar horizontal and maximizing the contact area between the conductive plate 201 and the busbar. The sliding nature of the baffle 401 and the conductive plate 201 facilitates clamping and abutting busbars of different widths. The compression spring 604 further abuts the sliding plate 602.This causes the sliding plate 602 to drive the locking block 605 to collide with the helical rack 606. Since the pointed teeth on the locking block 605 are in the opposite direction to those on the helical rack 606, the screw 203 will not rotate in the opposite direction after the locking block 605 and the helical rack 606 collide, ensuring a tight clamping and fixation of the screw 203 to the insulating plate 1. When the drive groove 207 is driven by a hex wrench, the wrench presses against the pressure rod 601, causing the pressure rod 601 to slide away from the compression spring 604. The locking block 605 separates from the helical rack 606, allowing the screw 203 to rotate freely, achieving both tightening and loosening operations. This effectively protects the screw 203. The movable rod 603 also guides the sliding plate 602, ensuring smooth and stable sliding without deviation. Simultaneously, it ensures smooth sliding of the pressure rod 601, preventing free rotation and improving drive control.
