And a central strength member(210) includes a strength rod providing tensile strength by being located at a center of the optical fiber cable and a foam coating layer providing a buffering operation as to external pressure and impact by being coated on the circumference of the central strength member. And an external coating(260) is bound by including the tubes and the strength rod and protects them from the external environment.
Abstract:
A wrinkle pattern coating composition is provided to embody a wrinkle pattern on a housing case of a handheld terminal, and reduce the production process and expense for embodying a wrinkle pattern. A wrinkle pattern coating composition includes a resin for spray coating, a hardener which causes a cross-linking reaction with the resin, and a volatile functional agent. A wrinkle pattern is formed on a housing case by applying the coating composition onto the surface of the housing case of a handheld terminal, and drying the coated layer. An application method of the wrinkle pattern coating composition includes the steps of: (S1) designing and manufacturing a mold in the housing case shape of a handheld terminal; (S2) processing the housing case according to the mold; (S3) spray-coating the surface of the housing case with the coating composition; (S4) drying the coating composition at 150-160 °C for 20-30 minutes; and (S5) uniting the housing case with the handheld terminal.
