1. An optical connector plug for outdoor waterproof onsite assembly, comprising:
an optical connector that is coupled to a tip of an optical cable cut on a site,
wherein the tip at one side of the optical cable (10) is attached to an assembly (20) in a sealing or mechanical manner, and a frame (40) sheathing an outer side of the optical cable (10) has one side end to which an outer peripheral edge of the assembly (20) is coupled, has one or more slits (42) which are cut from a middle to another side end and are formed to be widened and narrowed in compliance with an outer diameter of the optical cable (10), and has a step (41) on an outer peripheral edge at one side end to be held by an inner peripheral edge of a housing (60) so as to withstand tensile strength applied to the optical cable (10)
wherein the frame (40) sheathes a sleeve (30) and the optical cable (10),
wherein the sleeve (30) sheathes a sealing part at which a cut tip at one side of the optical cable (10) is attached to an end of an optical fiber of the optical cable (10) of the assembly (20),
wherein a fixing unit (50) is coupled to the other side end of the frame (40) to fix the frame (40) to an outer peripheral edge of the optical cable (10),
wherein the housing (60) is coupled to an outer side of the frame (40), and a protective cap (100) is coupled to one end of the housing (60) through a rotation cap (70),
wherein a protective tube (80) is coupled to sheathe another end of the housing (60) and the optical cable (10), and
wherein a boot (90) is coupled to an outer side of the protective tube (80) and inhibits the optical cable (10) from being excessively bent.
