い。As described above, according to the wedge type detention clamp for the manipulator method of the present invention, the electric wire receiving groove portion is incorporated into the clamp body having the inclined inverted U-shaped electric wire receiving groove portion at one end and the insulator connecting portion at the other end. A wedge-shaped body opposite to the wedge body is arranged in the center with a rotatable cylindrical operating piece orthogonally, and the long threaded part of the wedge shaft for wedge insertion that penetrates the inside of the wedge body in the longitudinal direction is laterally screwed into the operating piece. Since one end of the wire is protruded from the end of the clamp body and the operation nut is arranged, after guiding the bare wire of the tightly connected wire to the wire receiving groove, the nut of the wedge shaft bolt end of the wedge-shaped cylindrical operating piece Just turn it
The rotation of the bolt shaft is converted into the sliding movement of the wedge body, and the electric wire is easily wedged to obtain a gripping force. In this case, since the cylindrical operating piece (round nut) rotates around the operating piece in the wedge body, the bolt shaft follows the movement of the wedge body, which can be performed by a simple screw operation, and the wedge body can be operated. Since the lower end engaging step portion is guided by the engaging streak groove of the wedge guide groove portion, smooth sliding without blurring is achieved. Moreover, the wedge body can be inserted by a screwdriver operation that does not have a tapping action, and the electric wire can be retained, so that manipulator (robot) work can be performed. Also, since the wedge shaft for pulling in the wedge has a brim at its one end that contacts the inside of the clamp body, even when disassembling the clamp, simply turning the operation nut in the reverse direction will ensure that the wedge body will retract and the wedge will be tightened. Can be solved. If the operation nut, which will be a hexagonal nut, and the tightening bolt for the wire retainer at the rear end of the wedge are the same size, the work can be continued without changing the bolt / nut tool of the manipulator, which is efficient. . Further, the nut at the rear end of the wedge pull-in bolt shaft is prevented from falling off by the crimping or the spring pin, and the wedge body is not dropped.
