Description

Technical Field

[0001] The invention belongs to the technical field of busbars, and in particular relates to a busbar with adjustable contact finger positions. Background Art

[0002] The busbar is a conductor used to distribute and connect electricity in the power system. It is a high-energy-density electrical device commonly used in power distribution systems, substations, AC converter stations, and transformers. The busbar is connected to the power system by connecting the terminals at the power input end and distributes power to various loads such as motors, lighting, appliances, and other electrical equipment.

[0003] The busbar is provided with a plurality of contact fingers, which are connected to the wiring terminals on the electrical equipment. In actual use, the installation position of the electrical equipment will affect the installation position of the wiring terminals. However, most existing busbars are fixedly arranged, and the positions of the contact fingers on the busbar cannot be adjusted according to the installation position and size of the wiring terminals. It is easy for the wiring terminals to only partially fit with the contact fingers, which affects the stability and reliability of the busbar during use. Summary of the invention

[0004] In view of the problem that the position of the contact fingers on the existing busbar cannot be adjusted, the connection terminal and the contact fingers are prone to incomplete matching, which affects the matching stability of the busbar and the connection terminal, the following invention is now proposed:

[0005] A bus with adjustable contact finger positions comprises a bus body and a mounting seat, the bus body is provided with a plurality of contact fingers, the mounting seat is provided with a mounting groove, and slide grooves are provided on both sides of the mounting groove, and a mounting plate is drivingly connected to each side of the bus body, and a sliding head that is movably matched in the slide groove is provided on the side of the mounting plate, and grooves are provided on the front and rear sides of the sliding head. A first adjusting rod and a second adjusting rod located on the front and rear sides of the sliding head are threadedly connected in the slide groove, and convex heads matching the grooves are provided at the ends of the first adjusting rod and the second adjusting rod. After the first adjusting rod or the second adjusting rod is screwed in, the convex head presses the groove inwardly and pushes the sliding head to move horizontally along the slide groove.

[0006] After the slider moves along the slide slot, it drives the bus body to move horizontally to adjust the position of the contact finger. After the remaining adjustment rod is screwed in, the slider and the mounting plate can be fixed, and then the bus body can be fixed.

[0007] Furthermore, a height adjustment plate is provided at the bottom of the mounting seat, and a plurality of height adjustment feet and fixing holes are provided on the height adjustment plate. The ends of the height adjustment feet are threadedly connected to the bottom of the mounting seat, and fixing nuts are threadedly connected to the height adjustment feet. The fixing nuts are screwed into the height adjustment plate to fix the height adjustment feet on the height adjustment plate. By screwing in and out the height adjustment feet and the fixing nuts, the distance between the height adjustment plate and the mounting seat can be adjusted to adjust the height of the busbar body and the contact fingers, so as to adapt to wiring terminals of different heights.

[0008] Furthermore, a cover plate is fixedly provided on the top of the mounting seat, and a plurality of strip grooves for accommodating contact fingers are provided at the bottom of the cover plate. The strip grooves prevent the cover plate from affecting the horizontal movement of the contact fingers during the movement of the bus body.

[0009] Furthermore, the other ends of the first adjusting rod and the second adjusting rod are provided with matching grooves in the shape of hexagonal prisms, and the adjusting rods can be rotated only by using a tool matching the matching grooves.

[0010] Furthermore, card slots are provided on both sides of the bus body, and the mounting plate is provided with card heads that are horizontally engaged in the card slots. The mounting plate can be quickly mounted on the bus body through the card slots and the card heads.

[0011] Furthermore, a cross groove is provided at the bottom of the height-adjusting foot, and the height-adjusting foot can be screwed in and out using a corresponding tool.

[0012] The present invention provides a bus with adjustable contact finger positions, which has the beneficial effect that the contact fingers thereon can be moved by adjusting the position of the bus body so that the contact fingers are fully matched with the wiring terminals, thereby improving the stability and reliability of the bus during use.
