A plurality of optical fibers are coupled to the ferrule, and the optical connector is adapted to be abutted against another optical connector in an abutting direction. The positioning pin holes and the plurality of optical fibers are arranged in parallel with each other at least in the vicinity of the butt end face of the ferrule so that an arrangement plane of the plurality of optical fibers and the positioning pin holes is inclined at an inclination angle of .theta. with respect to a plane of the abutting direction, and so that a line where the butt end face and the arrangement plane cross each other is orthogonal to each axis of the plurality of optical fibers. The ferrule further includes a rear end portion arranged so that a pressing force is applied in a substantially vertical direction with respect to the butt end face when the optical connector is abutted against another optical connector and pressed in the abutting direction.

摘要： An optical connector that provides a housing body 21 and a fixed part 22 that are installed so as to hold a backplane 3, and connects an optical connector plug 4b inserted into said housing body 21 via an installation hole in said backplane 3 and another optical connector plug 4a inserted into said housing body 21 from the direction opposite to that of said optical connector plug 4b, wherein flexible claws 25 projecting from both sides of said fixed part 22 engage said housing body 21 via said installation hole 30 in said backplane 3, and thereby said backplane 3 is held between said housing body 21 and said fixed part 22. Simply by adjusting the floating range (amount of floating) of the flexible claws 25 within said installation hole 30 the floating range (amount of floating) of the housing body 21 can be reliably set. Thereby, when the housing body 2 engages the printed board housing, the dimensional error is offset reliably by the floating of the housing body 21, and the engagement is carried out smoothly. A special order part for setting the floating range of the housing body 21 is not necessary, and thus a lower cost is possible and assembly can be carried out easily. In addition, a structure can also be used wherein the flexible claws projecting from the housing body side engage the backplane by passing through the installation hole, and the backplane is held between the bearing walls on the side of the housing body.
