Portable optical fiber sheath anti-adhesion device

Abstract

The invention discloses a portable optical fiber sheath anti-adhesion device, and belongs to the technical field of communication optical fiber cables. The portable optical fiber sheath anti-adhesion device comprises a charging box, an air pressure adjusting valve and an air source triplet. The air source triplet is connected to the air pressure adjusting valve through an air pipe, the air pressure adjusting valve is connected with the charging box through an air pipe, the charging box is sealed space, anti-adhesion powder is stored in the charging box, and a wire inlet mold and a wire outlet mold allowing cables to penetrate are arranged on the two sides of the charging box respectively. Pressure of filtered air is adjusted through the air pressure adjusting valve, stable air pressure is conveyed into the charging box, the anti-adhesion powder is blown and is evenly scattered on cable cores, and the situation that due to the fact that the anti-adhesion powder is absorbed on the cable cores unevenly, the molds are blocked, and the cables are bulged is avoided. The air source triplet can fully filter out impurities and water in air, and therefore the situation that the impurities in the anti-adhesion powder gas is mixed into the anti-adhesion powder, the anti-adhesion powder is damped, and use is influenced is avoided.

Description

technical field [0001] The invention relates to an anti-adhesion device for an optical fiber sheath, specifically a portable anti-adhesion device for an optical fiber sheath used to solve the adhesion between a neutron cable and an outer sheath in indoor optical cable production, and belongs to the technical field of communication optical cable production. Background technique [0002] Fiber-to-the-home, fiber-to-the-home and fiber-to-the-desktop are the development trends of optical communications. As the best access medium at present, FTTH completely solves the access bandwidth problem and supports multiple interfaces such as data, video, and voice. In recent years, with the gradual extension of optical fiber in the access network to the user end and the final realization of optical fiber to the home, the demand for indoor optical cables at home and abroad has increased year by year, and the indoor optical cable market will become the future development direction of the o...

AI Technical Summary

Problems solved by technology

[0003] Branch optical cable is a kind of indoor optical cable, which is mainly used for connection from one terminal to multiple terminals, so it contains two or more optical cable subunits, because the sub-cable sheath and the outer sheath are generally made of the same material type of material, so the softening temperature of the two is similar, so in the production process, it is easy to appear that the sub-cable sheath is stuck to the outer sheath, resulting in the sub-cable not being able to move freely inside the outer sheath, and the actual operation of the neutron cable cannot be pulled out

In order to effectively avoid the mutual adhesion between the sub-cable sheath and the outer sheath, in the prior art, talcum powder is usually adsorbed on the surface of the sub-cable sheath to prevent the adhesion between the sub-cable sheath and the outer sheath. The powder supply is controlled, resulting in uneven adsorption of talcum powder on the cable core, resulting in defects such as clogging the mold and easy bulging of the optical cable.
