SHEARABLE FASTENER BOLT AND METHOD FOR CLAMPING ELECTRIC WIRES, AND ELECTRIC CONNECTOR COMPRISING A ZERO-PROTRUSION SHEARABLE FASTENER
The invention relates to a fastener bolt (1), an electric connector (70) and a method for clamping an electric wire (80). The fastener bolt (1) is provided with a shearing section (40). Due to the shearing section (40), a head section (8) of the fastener bolt (1) is sheared off automatically when the fastener bolt (1) is tightened against the electric wire (80) and a predetermined fastening torque (84) is exceeded. A thread section (6) of the fastener bolt (1) is hollow and has a predetermined tensile break strength. Once the head section (8) is sheared off, a nut part (4), which is screwed onto the thread section (6), is tightened against a wall (74) having a threaded hole (72), into which the fastener bolt (1) is screwed. By tightening the nut part (4) against the wall (74), a tensile stress (92) is generated in the thread section (6) between the nut part (4) and the threaded hole (72). When the tensile stress (92) exceeds the predetermined tensile break strength, the thread section (6) will break right above the threaded hole (72). The usage of the nut part (4) for breaking the thread section (6) directly above the threaded hole (72) ensures that the remaining thread section (6) does not protrude much from the threaded hole (72). This reduces the danger of injuries or damage to head shrink tubes by sharp edges of the broken section (6).
