Rail-mounted terminal block

摘要

A terminal block includes a housing adapted to be fixed to a support rail which has two flanges each with a right-angle lip along its free edge. Inside the housing are a metal bearing member which is fixed relative to the housing and a metal clamping member which is movable relative to the bearing member. Both these members have two branches. A screw passes through a bore in the bearing member. Hook faces on respective branches of the bearing member face towards the head of the screw and bearing faces on respective branches of the clamping member face away from the head of the screw. When the terminal block is mounted on a support rail at least one of the hook faces and at least one of the bearing faces bear on the rail. The clamping member is U-shaped, having a central part on the side of the bearing member opposite the head of the screw and side flanges embracing the bearing member. This central part is attached to the screw but can rotate relative to the screw.
