An optical fiber sleeve plastic guide device

Abstract

The present invention provides a device for guiding an optical fiber coating, wherein the device is structurally simple and efficient, and is used for molding wire cables. The device comprises an injection unit used for injecting the material of a protective layer; a molding unit used for molding the injected material of the protective layer into a protective layer structure and connected with the injection unit; and a transmitting and oil-filling unit used for transmitting optical fibers to the molding unit and carrying out oil filling on the optical fibers during the transmission process, and connected with the molding unit. According to the technical scheme of the invention, the conventional needle tubing structure in the prior art is not adopted by the above device, and the oil-filling part is externally arranged. In this way, the fiber paste is prevented from being heated all the time, and is also prevented from getting in contact with the material of the protective layer. Therefore, the formation of impurities or the blockage is avoided. The product quality problem due to the rubbing phenomenon between obstructs and optical fibers can be fundamentally solved.

Description

technical field [0001] The invention provides a simple and efficient optical fiber sleeve molding guide device for cable molding. Background technique [0002] With the advancement of science and technology, the speed of information transmission is required to be higher and higher. The emergence of optical cables is the emergence of optical cables. Optical cables are manufactured to meet optical, mechanical or environmental performance specifications. One or more optical fibers in the sleeve are used as the transmission medium and can be used alone or in groups. Communication cable assemblies; in my country, the broadband China strategy is being vigorously carried out, and with the development of fiber-to-the-home and 4G networks, the requirements for optical cable performance Gradually improve; [0003] As far as the bundle tube type optical cable is concerned, the main properties of the optical cable, including the loss of the optical fiber, the tensile and temperature char...

Problems solved by technology

[0003] As far as the bundle tube type optical cable is concerned, the main properties of the optical cable, including the loss of the optical fiber, the tensile and temperature characteristics of the optical cable, etc., depend to a large extent on the quality of the secondary coating, and the production of the optical fiber coating in the prior art A needle tube part is set in the device, through which the optical fiber passes through and the fiber paste outside the fiber is stabilized, but the fiber paste entering the needle tube along with the optical fiber will accumulate in the needle tube during long-term use, and due to the needle tube It is continuously heated in the production device, causing the accumulated fiber paste to gradually carbonize, and small granular blockages are formed inside the needle tube, so that the blockage will scratch the optical fiber during production, resulting in large attenuation of the optical fiber or fiber breakage in the tube. ;
