Feedthrough terminal block, particularly for connecting electric cables in lines or systems for electric traction

摘要

A feedthrough terminal block, particularly for connecting electric cables in lines or systems for electric traction, constituted by a modular structure composed of at least two modules which are mutually associated side by side. At least one of the modules is composed of a supporting element made of electrically insulating material which supports at least one pair of terminals made of electrically conducting material, which protrude from two opposite faces of the supporting element and are electrically interconnected. The supporting element is provided, on at least one of the faces that support the terminals, with at least one insulating wing which is adapted to separate the corresponding terminal from terminals of contiguous modules or from the outside. The terminal block comprises means for mutually assembling the various modules and means for fixing the terminal block to a wall at an opening formed in the wall itself.
