Disclosed is a terminal arrangement of electrical apparatus for connecting a cable to the apparatus. The terminal device comprises a frame (1) having a first and a second wall (4) of insulating material provided in parallel with each other, a bottom plate of insulating material provided between the first and the second wall, and a third wall standing on the bottom plate, such that a box-like space (6) is defined between the three walls and the bottom plate, the space being open at the side opposite to the third wall, wherein two grooves (5) opposing each other and extending from said open side toward said third wall are provided, one in each of the first and second walls (4), and a first recess (16) is provided in said bottom plate; an attachment piece (18) of insulating material having a box-like shape to fit into said box-like space (6) to be detachably accommodated therein and having a cylinder-like recess (18a) in a first face and a projection on a second face, opposite to said first face, the attachment piece (18) being positioned in said box-like space (6) such that its second face opposes said bottom plate and the projection engages said first recess (16) for preventing the attachment piece (18) from slipping off; and a terminal strip (3') having a terminal screw (10) for a terminal lug detachably mounted over said first face of the attachment piece in said box-like space (6) with lateral edges of the terminal strip (3') extending into and being guided by said grooves (5) and a screw section of the terminal screw (10) extending into said cylinder-like recess (18a) of the attachment piece (18) for preventing the terminal strip (3') from slipping off. The frame and the attachment piece (18) are structured in such a manner, that the attachment piece (18) and the terminal strip (3') as a unit may be replaced by a box-shaped terminal fitting (2) mounted on a terminal strip (3) such that the terminal fitting (2), instead of said attachment piece (18), is accommodated in said box-like space (6) and its terminal strip (3) has lateral projections (3a) extending into said grooves (5). <IMAGE> |
