Abstract:
1. An optical fiber coupling connector comprising: a circuit board; a plurality of light-emitting modules mounted on the circuit board; a plurality of light-receiving modules mounted separately from the light-emitting modules on the circuit board; an optical coupling module comprising a main body positioned above the circuit board and a plurality of converging lenses, the main body comprising a first optical surface, a second optical surface perpendicular to the first optical surface, and a reflection surface oblique relative to the first optical surface and the second optical surface, the converging lenses formed on the first optical surface and aligned with the light-emitting modules and the light-receiving modules; a receiving member coupled with the main body and comprising a front end portion and a rear end portion at opposite sides thereof, oppositely facing each other and defining a plurality of through holes extending from the front end portion to the rear end portion; and a plurality of optical fibers each having a body portion with a distal end and an optical lens formed therein, the body portions received in the through holes, the optical lenses protruding from the through holes and corresponding to the converging lenses; wherein the reflection surface is configured to reflect parallel light beams from the light-emitting modules toward the optical lenses and configured to reflect parallel light beams from the optical lenses toward the light-receiving modules; wherein the optical coupling module further comprises two plugs, the main body further comprises a front surface and a rear surface opposite to the front surface, the front surface defines a cutout, the main body further comprises a supporting surface and a stepped portion in the cutout, the stepped portion extends from the supporting surface and comprises the second optical surface and two mounting surfaces arranged at opposite sides of the second optical surface, the second optical surface recessed relative to the mounting surfaces, the front end portion comprises an optical coupling surface and two fixing surfaces arranged at opposite sides of the optical coupling surface, the optical coupling surface is recessed relative to the fixing surfaces, each of the fixing surfaces defines a fixing hole, the plugs plug in the fixing holes thereby fixing the receiving member to the optical coupling module, the receiving member is supported on the supporting surface, the mounting surfaces abut the fixing surfaces, and the optical coupling surface faces the second optical surface.
