Patent ID: 7232260

Claim:
An optical contact unit which constructs an elastic contact at which a ferrule A connected to a back end part of an optical fiber is faced and mechanically couples on another ferrule B placed at a front side of the ferrule A, comprising: said ferrule A; a tubular main body at least comprising: a ferrule holder which holds said ferrule A and the back end part to which said optical fiber of said ferrule A is connected; and an elastic member which gives said ferrule holder elasticity to translate in an optical axis direction of said optical fiber and holds said ferrule holder; and a tubular cable adaptor which is inserted to a back opening part of said main body and is penetrated by said optical fiber, wherein said main body comprises a first small diameter part which has a first contact plane extending approximately vertical from an internal surface of said main body toward an inside of said main body, wherein said cable adaptor comprises a large diameter part which has a second contact plane extending approximately vertical from the external surface of said cable adaptor toward an outside of said cable adaptor, wherein a maximum radius of said large diameter part is larger than a minimum radius of said first small diameter part, wherein said large diameter part is installed at a front side of said first small diameter part, wherein said second contact plane contacts to said first contact plane, and wherein said main body comprises: a slit which penetrates from the front opening part of said main body in the optical axis direction; and a concave part which fits with the rear edge part of a dividing sleeve unit comprising and keeping a dividing sleeve and is formed in the internal surface of the front opening part.
