Description

Bus bar fixing structure on power distribution cabinet

Technical Field

The utility model belongs to the technical field of power distribution cabinets, and relates to a bus bar fixing structure on a power distribution cabinet.

Background

The busbar of switch board is fixed with the cabinet body through the mode of splint generally, compress tightly the busbar on the cabinet body through the mode of splint fixation on the cabinet body promptly, in order to make busbar and cabinet body insulation, the busbar still needs the parcel insulating glue layer in fixed position, firm on the solid can reduce the negative influence of copper busbar heat extraction expansion and contraction in-process stress, in the above-mentioned traditional mode, not only the operation is comparatively inconvenient (dismouting splint operation is inconvenient in the narrow and small space), many busbar needs to operate respectively, moreover, the cabinet body backplate is pressed close to splint place, after installing other electrical components in the switch board, also very inconvenient when demolishing splint.

Disclosure of Invention

The utility model aims to solve the problems in the prior art and provide a bus bar fixing structure on a power distribution cabinet, and the technical problem to be solved by the utility model is to improve the portability of bus bar disassembly and assembly.

The aim of the utility model can be achieved by the following technical scheme: the utility model provides a bus bar fixed knot on switch board constructs, switch board includes cabinet body backplate, its characterized in that, bus bar fixed knot constructs including fixing insulating pad and the commentaries on classics roller on cabinet body backplate, the equal threaded connection in both ends of commentaries on classics roller is on cabinet body backplate, it personally submits circular shape constriction part to have a plurality of transversal framves on the commentaries on classics roller, constriction part forms an annular spacing groove on changeing the roller, the axis of constriction part is located the eccentric position department of changeing the roller, and each constriction part is coaxial, the portion of changeing roller and bus bar contact is insulating material.

Further, two mounting plates are fixedly arranged on the cabinet body backboard, and threaded holes matched with the end parts of the rotating rollers are formed in the mounting plates.

Further, the end part of the rotating roller extends out of the outer side surface of the mounting plate.

Further, the roller comprises a metal core rod and rubber coated outside the metal core rod.

When the bus bar is installed, the rotating roller is rotated to the deeper position of the limiting groove and is opposite to the insulating pad, at the moment, a larger gap is formed between the insulating pad and the peripheral surface of the contraction part, the bus bar can be inserted lightly, and after the bus bars of the same specification penetrate into the limiting groove and are well adjusted in position, the rotating roller is rotated to the shallower position of the limiting groove and is contacted with the bus bar, and at the moment, the bus bar can be compressed. Besides the installation that this scheme was except can accomplish many generating lines simultaneously, its dismouting is also very light, and occupation space is also less relatively, because the lateral wall of switch board does not generally set up electrical components, consequently, compare traditional dismouting mode more not with the internal other electrical components of cabinet interference.

Fig. 2 is a schematic view of a busbar fixing structure.

In the figure, 1, a cabinet backboard; 2. an insulating pad; 3. a rotating roller; 4. a limit groove; 5. and (3) mounting a plate.

Detailed Description

The following are specific embodiments of the present utility model and the technical solutions of the present utility model will be further described with reference to the accompanying drawings, but the present utility model is not limited to these embodiments.

The bus bar fixing structure on the power distribution cabinet shown in fig. 1 and 2 comprises an insulating pad 2 and a rotating roller 3, wherein the insulating pad 2 and the rotating roller 3 are fixed on a cabinet body back plate 1, the insulating pad 2 can be adhered to the cabinet body back plate 1, two ends of the rotating roller 3 are connected to the cabinet body back plate 1 through threads, the rotating roller 3 is provided with a plurality of shrinkage portions with circular cross sections, the shrinkage portions form an annular limiting groove 4 on the rotating roller 3, the axis of the shrinkage portions is located at the eccentric position of the rotating roller 3, the shrinkage portions are coaxial, and the contact parts of the rotating roller 3 and the bus bar are made of insulating materials.

Two mounting plates 5 are fixedly arranged on the cabinet backboard 1, and threaded holes matched with the end parts of the rotating rollers 3 are formed in the mounting plates 5.

The end of the rotating roller 3 extends out of the outer side surface of the mounting plate 5, and the end of the rotating roller 3 is provided with a design which is convenient for the tool for rotating the rotating roller 3 to use, such as a straight groove, a polygonal outline and the like.

The rotating roller 3 comprises a metal core bar and rubber coated outside the metal core bar, and the position of the limiting groove 4 is rubber, so that insulation among bus bars is kept.

When the bus bar is installed, the rotating roller 3 is rotated to the deeper position of the limiting groove 4 and is opposite to the insulating pad 2, at the moment, a larger gap is formed between the insulating pad 2 and the peripheral surface of the contraction part, the bus bar can be inserted lightly, and after the bus bars of the same specification penetrate into the limiting groove 4 and are well adjusted in position, the rotating roller 3 is rotated to the shallower position of the limiting groove 4 and is contacted with the bus bar, and at the moment, the bus bar can be compressed. Besides the installation that this scheme was except can accomplish many generating lines simultaneously, its dismouting is also very light, and occupation space is also less relatively, because the lateral wall of switch board does not generally set up electrical components, consequently, compare traditional dismouting mode more not with the internal other electrical components of cabinet interference.

The specific embodiments described herein are offered by way of example only to illustrate the spirit of the utility model. Those skilled in the art may make various modifications or additions to the described embodiments or substitutions thereof without departing from the spirit of the utility model or exceeding the scope of the utility model as defined in the accompanying claims.
