Claims

[Scope of utility model registration request]

An optical fiber connector that is formed in close contact with the outer periphery of the boundary between the end portion of the optical fiber where the outer sheath has been removed and the portion where the outer sheath remains, by integral molding using a synthetic resin, wherein the outer sheath is removed. a connecting portion in which a portion is buried; a fixing portion in which the remaining outer skin portion is embedded; and a slit drilled in the fixing portion with the remaining outer skin portion partially exposed; Extension parts extend from both the left and right ends of the rear end of the fixing part, respectively, to connect the optical fiber.
An optical fiber connector that is characterized by extending rearward while maintaining space.
