Patent ID: 8550728

Claim:
A connection method of an optical connector and an optical transmission element, using the optical connector including a connector housing, a stop-ring structure, and an optical fiber which penetrates the connector housing and the stop-ring structure and protrudes from an end part of the stop-ring structure towards a connection side, also using the optical transmission element including a tensile-strength fiber body, the connection method comprising: a fuse connection step of fuse-connecting a first end of the optical fiber of the optical connector with a second end of an optical fiber protruding from a transmission element terminal part of the optical transmission element; a covering step of inserting a fuse-connected optical fiber part and the tensile strength fiber body extending towards the stop-ring structure of the optical transmission element inside a reinforcing sleeve provided with a hot melt body in an inner peripheral surface of the reinforcing sleeve, the covering step also covering the transmission element terminal part of the optical transmission element and at least the end part of the stop-ring structure so that the transmission element terminal part and the end part of the stop-ring structure are bridged; and an integration step of integrating the fuse-connected optical fiber part, the tensile strength fiber body, the transmission element terminal part, and the stop-ring structure, by a hot melt resin melted from the hot melt body flowing into a gap inside the reinforcing sleeve and solidifying, due to heating and heat-releasing the reinforcing sleeve.
