Abstract

Abstract There is disclosed an optical fiber connector wherein, when housings (11, 13) are connected to each other, slidable contact of pushing pieces (18) causes elastic elements (31) to be deformed to push down locking elements (32) and abutment of an opening effector (16) causes guide pins (33) to move upwardly to rotate a hood body (28) in an exposing direction, and when the housings (11, 13) are separated from each other, abutment of a closing effector (17) causes the guide pins (33) to move downwardly to rotate the hood body (28) in a covering direction, whereby an end surface of an optical fiber (14) is covered and exposed by the rotation of the hood body (28). The end surface of the optical fiber (14) is completely covered and protected while the elastic elements (31) are prevented from being subjected to plastic deformation, and the reliability of the end surface protection of the optical fiber (14) is increased. <IMAGE>

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 461 words
An optical fiber connector including a module housing and an optical fiber housing, said module housing having a storage recess formed therein at its first end for housing a photoelectric element, said module housing further including a first opening at its second end, said optical fiber housing including a second opening at its first end, said optical fiber housing receiving at its second end an optical fiber so that a tip of said optical fiber is introduced generally to said second opening, said module housing further including a coupling portion at its second end, said optical fiber housing further including a coupling portion at its first end, said coupling portions of said module housing and optical fiber housing being connected to each other to bring an end surface of the tip of said optical fiber into contact with said photoelectric element, said optical fiber connector comprising: a pushing piece formed on an upper inner side of said coupling portion of said module housing; a cylindrical introducer formed inside of said coupling portion of said module housing for introducing the tip of said optical fiber, the inside of said coupling portion of said module housing communicating with said storage recess through said cylindrical introducer; a locking piece formed integrally with an upper portion of said coupling portion of said optical fiber housing; a hood body rotatably mounted in said coupling portion of said optical fiber housing for covering and exposing the end surface of the tip of said optical fiber; an elastic element formed integrally with said hood body and extending upwardly on a side surface of said hood body; a locking element formed integrally with said elastic element at its upper end and abutting against said locking piece, said locking element being pushed downwardly of said locking piece by slidable contact of said pushing piece when said housings are connected to each other; an opening effector formed on said introducer and having an inclined surface approaching said first opening at the second end of said module housing from top to bottom, said opening effector rotating said hood body in a direction to expose the end surface of the tip of said optical fiber by slidable contact of a lower portion of said hood body with said inclined surface when said housings are connected to each other; a pair of guide pins formed integrally with said hood body at its opposite lower side ends; and a pair of closing effectors formed on opposite side wall inner surfaces of said coupling portion of said module housing for slidably contacting said pair of guide pins respectively to rotate said hood body in a direction to cover the end surface of the tip of said optical fiber when said housings are separated from each other.
Claim 2
Dependent Claim 46 words
The optical fiber connector of claim 1, wherein said pair of closing effectors are formed on the opposite side wall inner surfaces of said coupling portion of said module housing in projecting form extending from said second end of said module housing toward the center thereof.
Claim 3
Dependent Claim 43 words
The optical fiber connector of claim 2, wherein each of said pair of closing effectors has an end surface inclined in a direction away from said storage recess from top to bottom adjacent the center of said coupling portion of said module housing.
