Description

Technical Field

[0001] The utility model relates to the technical field of conductive materials, in particular to a high-temperature resistant copper-aluminum alloy busbar for a photovoltaic inverter. Background Art

[0002] An inverter is a converter that converts direct current into alternating current. Copper-aluminum alloy busbar is a conductive material commonly used in inverters. Its connection method needs to take into account factors such as current carrying capacity, contact resistance, and thermal expansion coefficient. Common copper-aluminum alloy busbar connection methods include crimping, welding, and bolting. Crimping is simple and reliable, but it is necessary to select appropriate crimping tools and crimping dies to ensure crimping quality. Welding has high strength, but attention must be paid to the selection of welding process and materials to avoid welding defects and oxidation. Bolted connection is convenient for disassembly and maintenance, but it is necessary to select appropriate bolts and nuts to ensure connection reliability. Since bolted connection facilitates subsequent maintenance of equipment, its usage rate is higher than that of the other two connection methods.

[0003] However, the bolt connection method cannot connect the aluminum alloy bars quickly and conveniently, thereby reducing the connection efficiency. Therefore, a high-temperature resistant photovoltaic inverter copper-aluminum alloy bar is proposed. Utility Model Content

[0028] The top of the two slide bars 605 are fixed with the same pressing plate 606, and the sliding plate 606 is sleeved with a first spring 607. The top of the first spring 607 is fitted with the inner wall of the top of the mounting seat 601, and the bottom end of the first spring 607 is fitted with the top of the pressing plate 606. The top of the two slide bars 605 is fixed with the same pulling plate 608, and the pulling plate 608 is fitted with the rectangular groove 603. The pulling plate 60 The top of 8 is provided with a storage groove 609, and a rocker plate 610 is movably provided in the storage groove 609. When the rocker plate 610 is hidden, it can easily drive the pulling plate 608 to move the pressure plate 606 up, which is convenient for positioning and disassembly of the connecting plate 2. A positioning shaft is fixed in the storage groove 609, and the rocker plate 610 is movably connected to the positioning shaft. A second spring 611 is fixedly provided at the bottom of the rocker plate 610, and the bottom end of the second spring 611 is fixedly connected to the storage groove 609. A limit rod 612 is fixedly provided at the bottom of the rocker plate 610. Put the connecting plate 2 into the mounting seat 601 and make the two positioning protrusions 4 at the bottom fit into the positioning groove 602.

[0029] Working principle: When it is necessary to connect two adjacent copper-aluminum alloy bar bodies 1, squeeze the seesaw 610 away from one end of the limit rod 612, and the seesaw 610 rotates with the positioning axis as the origin and squeezes the second spring 611.
