<p>PROBLEM TO BE SOLVED: To prevent the occurrence of strains in the attaching surface of an attaching section when a cylindrical press-fitting section is compressed, by integrally forming the section between part of the cylindrical external side face of the press-fitting section and the attaching section through a connecting section which is more constricted than both end faces of the press-fitting section. SOLUTION: A connecting section 2c has constricted parts 2h formed of hollows from the top and bottom sides. Therefore, the thickness A of the section 2c in the vertical direction is smaller than the thicknesses L of both ends faces of a cylindrical press-fitting section 2a. The twisted conductor of a flat-type cable and the conductor of a branch line are press-fitted to the press-fitting section 2a by compressing the press-fitting section 2a from both the left and right sides. When the conductors are press-fitted to the section 2a, the stresses generated in the section 2a are hardly transmitted to the fitting section 2b, because the stresses are concentrated to the constricted part 2h. Since the flat attaching surface of the attaching section 2b is strained, the possibility of the attaching surface of a circuit breaker being positioned unstably is eliminated.</p> |
