Abstract

721,972. Binding-posts. CALOR-EMAG ELEKTRIZITATS AKT.-GES. July 14, 1952, No. 17732/52. Class 38 (1). [Also in Group XXXVII] In a switchgear structure (see Group XXXVII). adja. cent bus-bar sections are connected together and to a supporting conducting strap or connection 2 by a conducting member 3 which is in two parts and has annular beads engaging the ends of the bus-bar sections. The two parts are clamped together and to the strap 2 by a U-shaped clamping bolt 4. This arrangement permits some axial and angular displacement to occur between the bus-bar sections.
