Abstract
An electric connector comprises a wall surrounding a receptacle that receives a strand of an electric wire and having a threaded hole extending through the wall and opening into the receptacle, and a fastener bolt screwed into the threaded hole and clamping the electric wire. The fastener bolt includes a bolt part having a head section, a thread section and a shearing section connecting the head section and the thread section. The fastener bolt further includes a nut part screwed onto the thread section. The shearing section is adapted to break if a predetermined fastening torque is exceeded. The thread section is hollow and has a predetermined tensile breaking strength.
