Claims

[Claims for Utility Model Registration] 1. An optical fiber core wire consisting of an optical fiber strand and a coating layer of the optical fiber strand, the coating layer of which is peeled off and the optical fiber strands are connected through a connection part, In an optical fiber connection part, the connection part has an optical fiber connection protection part formed so that a protective member is attached to cover layer parts on both sides of the connection part, and both sides of the optical fiber connection protection part. a sleeve fixing portion which is arranged close to each other and formed into a vertically divided cylindrical shape, and whose outer diameter is larger than that of the vertically divided cylindrical covering layer pressing member; and the covering layer pressing member which is pressed against the outer periphery of the covering layer. a vertically split cylindrical crimping fitting made of a member; and a connecting sleeve that is fitted into the outer layer of the sleeve fixing part of the vertically split cylindrical crimping fitting on both sides of the optical fiber wire connection protection part and fixed integrally. An optical fiber core connection section characterized by being provided with.
. 2. The optical fiber/(' core wire connection portion) according to claim 1, wherein a rubber cushion is interposed between the coating layer and the coating pressure member.
