Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic installation parts, in particular to a connecting piece for photovoltaic modules. Background Technique

[0002] When installing photovoltaic modules, connecting pieces such as edge pressing blocks and middle pressing blocks are required. At present, there are still certain problems in the use of traditional middle pressing blocks. For example, the traditional middle pressing blocks lack a structure for alignment. During the installation on the bracket, it is necessary for workers to visually observe whether it is on the same horizontal line as the photovoltaic bracket. However, when tightening the bolts, it is easy to drive the middle pressing block to deviate by a certain angle, which easily leads to uneven force during the pressing of the photovoltaic module, resulting in hidden cracks in the photovoltaic module. At the same time, the traditional middle pressing block needs to be used in cooperation with a tensioning block. The tensioning block is placed inside the bracket section steel and clamped, and bolts are used to tighten the middle pressing block. Although the purpose of fastening the middle pressing block can be achieved, it is very easy for the tensioning block to be driven by the screwing force of the bolts, causing its angle to change, forming a virtual buckle between the tensioning block and the bracket section steel, resulting in the situation that the middle pressing block presses the photovoltaic module unstably.
