Abstract
A ferrule for an optical connector, comprising: a ferrule body formed of a resin and including a through-hole having an inner wall for releasably receiving an optical fiber, the inner wall of through-hole being defined by a large-diameter portion and a small-diameter portion which are axially aligned; and a metallic pipe disposed on at least part of the inner wall of the through-hole, said metallic pipe being formed of at least one of an alloy of iron-nickel and an alloy of iron-nickel-cobalt.
Claims22
A ferrule for an optical connector, comprising:
- a ferrule body formed of a resin and including a through-hole having an inner wall for releasably receiving an optical fiber, the inner wall of through-hole being defined by a large-diameter portion and a small-diameter portion which are axially aligned;
- and
- a metallic pipe disposed on at least part of the inner wall of the through-hole, said metallic pipe being formed of at least one of an alloy of iron-nickel and an alloy of iron-nickel-cobalt.
A method for manufacturing a ferrule for an optical connector, comprising the steps of:
- fixing one end of a metallic pipe to a pin of a metallic mold;
- arranging one or more metallic molds around the metallic pipe to form a space between the metallic molds and the metallic pipe;
- charging a resin for a ferrule body into the space;
- and
- curing the resin.
A method for manufacturing a ferrule for an optical connector, comprising the steps of:
- fixing one end of a metallic pipe to a pin of a metallic mold;
- fixing another opposing end of the metallic pipe by way of a movable body which is urged against the metallic pipe;
- arranging metallic molds around the metallic pipe to form a space between the metallic molds and the metallic pipe;
- charging a resin for a ferrule body into the space;
- and
- curing the resin.
A metal article having a through-hole, wherein the metal article is composed of an electro-casted body of an iron-nickel alloy or iron-nickel-cobalt alloy.
A manufacturing method of a metal article having a through-hole, comprising the steps of:
- arranging a core material in an electro-casting plating bath;
- forming an electro-casting body of an iron-nickel alloy or iron-nickel-cobalt alloy on the surface of the core material;
- and
- removing the core material from the electro-casting body to obtain the metal article.
