Connector for optical fiber

Claim 1

A connector for an optical fiber cable having an optical fiber in a cable covering, said connector including a holding member comprising: a front cylindrical part for holding an end of the optical fiber; a rear cylindrical part for holding the optical fiber cable which is integrally provided with said front cylindrical part and which has a length between its opposite ends provided with an outer surface of a first diameter and an inner surface in contact with the cable covering of the optical fiber; at least one slit formed along said rear cylindrical part extending in an axial direction of the optical fiber; a plurality of notches in said rear cylindrical part intersecting said at least one slit in a circumferential direction of the optical fiber, said notches extending radially to the outer surface of said rear cylindrical part at an intermediate portion of the length thereof; and a fixed member having an inner surface with a diameter less than said first diameter of said outer surface of said rear cylindrical part, which is pressed on to said outer surface at said intermediate portion where said recesses are located for applying pressure by said lesser diameter to press said rear cylindrical part in a radially inward direction thereof to securely hold the optical fiber cable from axial displacement, wherein the outer surface of said rear cylindrical part beyond said fixed member becomes projected radially outward relative to said inner surface of said fixed member to securely hold said fixed member thereon, and said fixed member can be removed by axially pulling said fixed member over the outer surface of said rear cylindrical part.
