Claims

[Scope of utility model registration request]

It has a contact pin at one end, a light receiving element and/or a light emitting element electrically connected to the contact pin inside, and a ferrule holding the tip of the fiber in the fiber cable is fixed to the other end. , an optical plug that is used by inserting the contact pin and connecting it to a socket,
Engageable projections and depressions are provided at opposing positions of the ferrule and the support base to which the light-receiving element and/or the light-emitting element is fixed, and when the projections and depressions fit together, the tip of the fiber is connected to the light-receiving element and the ferrule. and/or an optical plug configured by positioning the ferrule so as to face the reproducing element.
