Abstract

PURPOSE:To improve impact resistance strength of the coupling end face of an optical connector by molding the entire circumference of the coupling end face of an elastic material having the Young's modulus lower than the Young's modulus of a V-grooved base plate without allowing guide pin holes to come into contact with guide pin V-grooves. CONSTITUTION:The end face of the guide pin V-grooves 12 is previously chamfered prior to the resin molding and the resin molding is executed while the guide pins are held pressed to the V-grooves 12, by which the guide pin holes 3 formed of the elastic material molded part 4 over the entire circumference is obtd. The stage is, therefore, simple and in addition, the resin amt. in the peripheral part of the guide pin holes 3 is adjusted as desired by changing the vertical angle of a blade for chamfering to adjust a chamfering angle. The impact resistance at the coupling end face of the optical connector is improved in this way.
