Electrical connecting terminal, especially a transformer protective-earth conductor terminal

摘要

An electrical connecting terminal, especially a transformer protective-earth conductor terminal, having a terminal housing (1) consisting of electrically insulating material, a metallic conductor terminal body (2) arranged in the terminal housing (1), and a metallic connecting rail (3) arranged in the terminal housing (1), the conductor terminal body (2) having a conductor retaining space (4) and, preferably, being designed as a screw connecting body with a terminal sleeve (6) a terminal screw (7) screwed into the terminal sleeve (6), and a pressure and conductor protection element (8), the connecting rail (3) having a connecting strip (9) which is guided in the conductor retaining space (4), and the connecting rail (3) having on the rear side of the terminal housing (1) a connecting surface (10), which projects out of the terminal housing (1) and is exposed on the outer surface on the terminal housing (1), for mechanical fastening and electrical connection to a mating surface, can be used universally in a manner which conforms with industrial requirements in that the terminal housing (1) is essentially open on the rear side and in that the connecting rail (3) can be inserted with the connecting strip (9) directly into the terminal housing (1) from the rear side, or the terminal housing (1) can be fitted directly onto the connecting rail (3) from the front, with the connecting strip (9). <IMAGE>
