Patent ID: 7140785

Claim:
An optical connector assembly which connects optical communication devices detachably to each other, said assembly comprising: a plug connector having a first optical element for pci-forming any one of emission and receipt of light, and a first lens, the first optical element and the first lens having a first optical axis identical to each other; and a receptacle connector having a second optical element for performing the remained one of the emission and receipt of light, and a second lens, the second optical element and the second lens having a second optical axis identical to each other, wherein the plug connector includes a convex portion having sectional configuration of round arch a diameter of which is gradually diminished along the first optical axis, and a plug portion formed on a forward end of the convex portion, said plug portion being perpendicular to the first optical axis, wherein the receptacle connector includes a concave portion into which the convex portion is inserted and a receptacle portion formed in a bottom of the concave portion, said receptacle portion being perpendicular to the second optical axis, wherein any one of the plug connector and the receptacle connector has supporting mechanism that supports the connector movably, and wherein the curvature of the convex portion of the plug differs from the curvature of the concave portion of the receptacle such that, when the concave portion and convex portion are brought into contact, the convex portion contacts only an outer edge of the concave portion.
