The coaxial cable connector connecting device according to claim 1, which is configured to ensure vertical positioning of the outer conductor shell with respect to the cylindrical jig.   The chuck portion has a pair of chuck arms that sandwich the cylindrical portion of the outer conductor shell fitted to the cylindrical jig, and is engaged with the slits of the cylindrical portion on the gripping surfaces of both chuck arms. 3. A projecting portion that is fitted is provided, and the circumferential positioning of the outer conductor shell with respect to the cylindrical jig is ensured by the engagement between the slit and the projecting portion. For coaxial cable connectors.   The bending means is provided closer to the crimping position than the cylindrical jig, an operating rod provided on the positioning holding member so as to be slidable in the moving direction, and projecting at one end of the operating rod. A pressing body facing the crimping ring portion of the outer conductor shell held in a standing posture by being fitted to a jig, and a pressing spring fitted to the other end of the operating rod. The pressing body is urged in a direction away from the cylindrical jig by a spring, and when the positioning holding member moves to the crimping position, the other end of the operating rod comes into contact with the device fixing portion, The operating rod moves so as to approach the cylindrical jig against the push spring, and is configured to press the lid and the crimping ring portion by the pressing body and bend the connecting piece. The coaxial cable according to claim 1, 2 or 3 Wire connection device of use connector. The positioning holding member has an opening through which the crimp lower tooth mold provided on the movable support base is inserted at a location adjacent to the cable guide body side of the cylindrical jig, and the positioning holding member is The movable support base is supported so as to move up and down, and is biased to an upper limit position by a spring means.
At the crimping position, the positioning holding member is pushed down by the crimping die, and the crimping lower tooth mold projects upward through the opening, and crimps the crimping mouth ring part in cooperation with the crimping upper tooth mold. The coaxial cable connector connecting device according to any one of claims 1 to 4, which is configured as described above.   The insulating pin accommodated in the cylindrical portion of the outer conductor shell, which is lifted by an operating arm and is fitted to the cylindrical jig, and is pushed up in the cylindrical hole of the cylindrical jig so as to be movable up and down. The coaxial cable connector connecting device according to any one of claims 1 to 5, further comprising push-out means for pushing up the housing and removing the outer conductor shell from the cylindrical jig.
