A fastener bolt for clamping an electric wire includes a bolt part and a nut part. The bolt part has a head section, a thread section, and a shearing section connecting the head section and the thread section. The nut part is screwed onto the thread section. The shearing section is configured to break if a predetermined fastening torque is exceeded. The thread section is hollow and has a predetermined tensile breaking strength.
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).

The contact section has a tapered penetration portion establishing electrical contact with a stranded wire. A length of the penetration portion is at least three-quarters of a diameter of the binding screw in the threaded section.
An electrical connector is disclosed. The electrical connector has a first body and a second body. The second body is mechanically coupled to the first body in a coupling state and enters the coupling state through a lateral side of the first body.
