Mid-joints Mid-joints is used for connecting adjacent aluminium plate, structure design conforms to inner section shape of aluminium plate, composed by two connection board。 In order to make good electrical contact between middle joint and aluminium row, outside surface of each connected plate is designed several element rest, and contact with aluminium row continuously. Besides, in order to ensure the connected aluminium row alignment, each connection board designed is automatic alignment structure. Thread hole of middle joint use special measure anti-loose to ensure the reliability of the joint anti-loose.
