Description

Technical Field

[0001] The utility model relates to the field of busbar fixing, and particularly relates to an installation and fixing structure for a busbar of a high-current power distribution cabinet. Background Technique

[0002] The busbar generally refers to the copper bar in the power distribution cabinet, which is the power busbar in the power distribution cabinet and has the ability to conduct large currents. To ensure the stability of the busbar during installation, a fixing structure is used to fix the busbar when it is installed inside the power distribution cabinet.

[0003] Currently, the fixing structure of the busbar is to first use screws to pass through the installation holes of the busbar and connect with the support structure, and then connect the support structure of the fixing structure with the bracket inside the power distribution cabinet.

[0004] When the above structure is used to fix the busbar, when the position of the bracket inside the power distribution cabinet is higher or lower than the installation hole of the busbar, the position of the busbar fixing structure cannot be adjusted, and it is necessary to open holes in the busbar on-site, and then adjust the fixing structure and the bracket to correspond to the position. This not only has poor flexibility, but also the on-site hole opening is cumbersome, which is not conducive to quickly realizing the fixing work of the busbar.

[0005] In order to solve the above problems, we propose an installation and fixing structure for a busbar of a high-current power distribution cabinet. Content of the Utility Model

[0012] With the above technical solution, through the arrangement of the sliding groove and the slider, it is used to linearly guide the fixing block, and the function of the bearing is to allow the rotating rod to rotate inside it, so that the fixing block can rotate.

[0013] The present utility model is further configured as: the twelve threaded holes are arranged in a circular ring, and two of the threaded holes respectively correspond to two fixing screw holes.

[0014] With the above technical solution, two of the twelve threaded holes arranged in a circular ring will correspond to two fixing screw holes every time they rotate. After connecting two positioning screws to two threaded holes and two fixing screw holes respectively, the insulating shell can be rotated and fixed, so that the fixing structure can adapt to the fixing work of busbars at various angles.

[0015] The present utility model is further configured as: a guide groove is formed on one side of the insulating shell close to the first fixing plate, and the first fixing plate is slidably connected to the inside of the guide groove.

[0016] With the above technical solution, through the arrangement of the guide groove, it is used to guide the first fixing plate and prevent the first fixing plate from rotating following the clamping screw.

[0017] The present utility model is further configured as: the clamping screw is rotatably connected to the inside of the insulating shell through a bearing, and one end of the clamping screw penetrates to the outside of the insulating shell and is fixedly connected with a turning handle.

[0018] With the above technical solution, through the setting of the rotating handle, it is convenient for the user to rotate the clamping screw, thereby adjusting the distance between the first fixing plate and the second fixing plate to achieve the clamping and fixing of the busbar; through the setting of the bearing, it is used to limit the rotation of the clamping screw to a fixed position only.

[0031] Furthermore, installation holes are formed inside both the connecting plate 1 and the connecting block 2. By providing the installation holes, it is convenient for installers to use screws to install and fix the connecting plate 1 and the bracket inside the power distribution cabinet.

[0032] Further, a chute 11 is formed on one side of the connecting plate 1 close to the fixed block 4. A slider 12 fixedly connected to the fixed block 4 is slidably connected inside the chute 11. The inside of the slider 12 is rotatably connected to a rotating rod 15 through a bearing.

[0036] Brief description of the usage process: When in use, first use screws to pass through the mounting holes inside the connecting block 2 or the connecting plate 1 and fix them to the power distribution cabinet bracket;

[0037] Then separate the two positioning screws 6 from the two fixed threaded holes 3, pull the fixed block 4 up and down to adjust the height of the insulating shell 7. After adjusting to a suitable position, pass the two positioning screws 6 through the two threaded holes 5 and thread them into the two fixed threaded holes 3 to position the insulating shell 7;

[0039] Among them, when the clamping screw rod 8 rotates clockwise, it can drive the first fixing plate 9 to approach the second fixing plate 10, and when the clamping screw rod 8 rotates counterclockwise, it will drive the first fixing plate 9 to move away from the second fixing plate 10;

[0040] If the angle of the insulating shell 7 is changed to adapt to the clamping and fixing of the busbar at different angles;

[0041] The installer separates the two positioning screws 6 from the two fixing screw holes 3, and rotates the fixing block 4 to drive the rotating rod 15 to rotate inside the bearing. Each time the fixing block 4 rotates, two threaded holes 5 will correspond to the two fixing screw holes 3. After reaching the appropriate angle, the two positioning screws 6 are threaded into the corresponding two fixing screw holes 3 again to fix the angle of the fixing block 4 after rotation, thereby fixing the angle of the insulating shell 7 connected to the fixing block 4. By rotating the clamping screw rod 8, the first fixing plate 9 is moved closer to the second fixing plate 10 to clamp and fix the busbar.
