Abstract

An optical connector plug for outdoor waterproof onsite assembly. A frame having slits sheathes and is fixed to an optical cable when the optical cable is constructed on a site. The optical connector plug is waterproofed by a protective tube and an O-ring. The optical cable has a tip at one side which is attached to an assembly in a sealing or mechanical manner, and the frame sheathing an outer side of the optical cable has one side end to which an outer peripheral edge of the assembly is coupled, has the one or more slits which are cut from a middle to the other side end and are formed to be widened and narrowed in compliance with an outer diameter of the optical cable, and has a step on an outer peripheral edge at one side end to be held by an inner peripheral edge of a housing.

Dependent claims

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.

A method for manufacturing an optical connector plug for outdoor waterproof onsite assembly, the 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), the method comprising:

a step (S10) of cutting the optical cable (10) based on a construction length of the optical cable on a site where the optical cable (10) is constructed;
a step (S20) of connecting the tip at one side end of the cut optical cable (10) to another side end of the optical cable (10) which is coupled to the assembly (20) and sheathing an attachment part by inserting a sleeve (30) into a connection part;
a step (S30) of sheathing an outer side of the connected optical cable (10) with the frame (40) and inserting and fixing the assembly (20) into an edge at one side of the frame (40);
a step (S40) of coupling a fixing unit (50) to an edge at another side of the frame (40) to fix the frame (40) through compression;
a step (S50) of coupling a protective cap (100) protecting the assembly (20) to one end of the frame (40) and coupling and fixing the housing (60) to the outer peripheral edge of the frame (40) by coupling the protective cap (100) to a rotation cap (70);
a step (S60) of coupling a protective tube (80) such that a side of the housing (60) is partially sheathed to fulfill waterproofing and an outer peripheral edge of the optical cable (10) is sheathed;
and
a step (S70) of protecting the optical cable from excessive bending by coupling a boot (90) to an outer side of the protective tube (80).
