FIELD: electricity. ^ SUBSTANCE: slide-in unit includes several contact units (12) for arrangement of contact of distribution device with copper bus (14). Each contact unit (12) has on both sides of brush (22) at least one contact pin (18) and one spring respectively, which are retained in the frame. Pins located opposite each other form mechanical unit of one half of the frame even without brush. At that, pins are pressed by means of appropriate springs. So pins form mechanical unit which has the possibility of being moved as whole entity along the brush from opening position to working position and vice versa. Brush is narrowed on its end so that opposite lying pins moved along the brush turn towards each other. ^ EFFECT: simplifying the design and reducing the required contact forces. ^ 22 cl, 11 dwg |
