Abstract

Abstract An optical connector for connecting optical fibers, comprises: a guide-groove substrate having grooves for positioning optical fibers and guide pins; an upper plate having groove portions each for covering the guide pins positioned in the guide grooves of the guide-groove substrate; elastic guide-pin pressing members each provided in the groove portions of the upper plate above portions where the guide pin grooves are in contact with the guide pins. In such a arrangement, it is preferable to form an oxide film on said V-grooves of the guide-groove substrate at least in the vicinity of contact points between the guide pins and the V-grooves. The optical connector further includes a resin molding portion for surrounding the substrate and the upper plate, the resin molding portion including a pair of opposite opened portions at a front and back surfaces thereof.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 105 words
An optical connector for connecting optical fibers, comprising: a guide pin; a guide-groove substrate having guide grooves for positioning said optical fibers and said guide pin, said guide pin contacting a predetermined location on one of said guide grooves by which said guide pin is positioned; an upper plate having a groove portion for covering said guide pin positioned in said one of said guide grooves when said upper plate is coupled to said guide-groove substrate; and an elastic guide-pin pressing member provided in said groove portion at a position above said location where said one of said guide pin grooves contacts said guide pin.
Claim 2
Dependent Claim 105 words
An optical connector for connecting optical fibers, comprising: a guide pin; a guide-groove substrate having guide grooves for positioning said optical fibers and said guide pin, said guide pin contacting a predetermined location on one of said guide grooves by which said guide pin is positioned; an upper plate having a groove portion for covering said guide pin positioned in said one of said guide grooves when said upper plate is coupled to said guide-groove substrate; and an elastic guide-pin pressing member provided in said groove portion at a position above said location where said one of said guide pin grooves contacts said guide pin.
Claim 3
Dependent Claim 22 words
An optical connector as claimed in claim 1, wherein said upper plate has an opening portion therein communicating with said groove portion.
Claim 4
Dependent Claim 49 words
An optical connector as claimed in claim 1, further comprising a resin molding portion, disposed about said guide-groove substrate and said upper plate, for covering said guide-groove substrate and said upper plate; and wherein said elastic guide-pin pressing member and said resin molding portion comprise the same resin material.
Claim 5
Dependent Claim 23 words
