Abstract

PURPOSE:To extremely facilitate wiring operation of optical by providing the main body of a long belt-shaped holder made of a synthetic resin with at least two thin holes in parallel to each other a littler thicker than the outside diameter of an optical fiber provided with a protective film, and forming a cut line at the thin wall part of each of these thin holes in the longitudinal direction. CONSTITUTION:Each of two optical fibers 6 is fitted into a thin hole 2 by intruding it into the opening formed by a cut line 3, and held with the main body of a holder 1. Since the edges of each opening are of thin walls and a slight thrust bends the edges of the opening downward, each fiber 6 can be fitted easily into the holder. After the end of the fitting, the edges pushed downward return to its initial positions automatically due to their own elasticity, and cover the fiber 6.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a holder for wiring optical fibers used in communications and the like.

In recent years, optical fibers have been used as communication lines in buildings, factories, and hospitals, and as wiring for information transmission means in office automation systems.

Optical fibers are thin wires that have a core made of glass or plastic that conducts light, a cladding that is a light-shielding coating on the outer periphery of the core, and primary and secondary coatings, ie, protective coatings, on the outer periphery of the cladding. Cables used for telephone and other communications are bundled with thousands of optical fibers and protected by a cable jacket layer, so there is no damage to the cables, but indoor wiring requires at least two output and input lines. unit, and does not use a strong jacket layer like the cables described above. Therefore, when wires are connected to a floor or wall, they may break due to contact with other objects, etc. (l), and the extremely thin protective coating will be damaged, making it impossible to perform its function. Therefore, it is necessary to protect the fiber coating, but in this case, it is desirable to have a holder that allows easy insertion of the fiber wire in order to improve work efficiency. Furthermore, since such wiring is a thin wire, we would like to have a holder that has the function of fixing it to the floor or wall.

In view of the above problems, the present invention provides a newly developed optical fiber wiring holder.

Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a main body of a belt-shaped elongated holder made of synthetic resin. This holder main body 1 is provided with at least two thin holes 2 in the longitudinal direction, each having a diameter slightly larger than the outer diameter of the optical fiber 6 coated with a protective coating as shown in FIG. A tearing line 3 is provided in the longitudinal direction in a part of the thin walled part of the thin hole 2, which serves as an opening when the optical fiber 6 enters and exits.

Further, a V-shaped or semicircular recess 4 near the outer surface of the cleavage line 3 and a V-shaped hole 2 at the midpoint between the %2 hole 2 on the outer surface of the holder body 1 on the opposite side of the recess 4 are also formed. The four parts 5 of the shape are formed.

Furthermore, as shown in FIG. 4, both sides of the holder main body 1 (
Alternatively, a tape-shaped lug 7 may be formed along the longitudinal direction on one side.

Furthermore, it is also possible to make a single unit including one set of two small holes 2 shown in FIG. 1 into a plurality of sets of continuous bodies as shown in FIG.

The molding of the holder main body 1 having such a microtunnel-like thin hole 2 is possible by using extrusion molding technology using a die, similar to the molding of a synthetic resin fastener that engages fine irregularities.

Since the present invention has the above configuration, the optical fiber 6 is inserted into the narrow hole 2 by pushing the optical fiber 6 into the opening formed by the cut #3, as shown in FIG. Holding with one body IVc.

In addition, when pushing the optical fiber 6 as described above, since the tip of the cutting opening is thin,
Even if the optical fiber 6 is pushed with a slight pressing force, the tip of the opening is pushed downward, so that it can be easily inserted.

After the insertion of the optical fiber 6 is completed, the tip of the opening, which had been pushed downward, automatically returns to the state before insertion due to its elasticity and covers the optical fiber 6.

Further, since the opening is a linear opening formed by cutting, even after the optical fiber 6 is inserted, the optical fiber 6 is almost completely covered and protected.

In addition, the 7'CV-shaped or semicircular four parts 4 formed near the outer surface of the cutting line 3 function as a guide for the optical fiber 6 when the optical fiber 6 is pushed into the narrow hole 2 manually or mechanically. As shown in FIG. 2, the recess 5 is a holder main body 10 which opens the tear line 3 by external pressure when the optical fiber 6 is pushed in. Both sides of the holder main body 10 expand outward to facilitate the insertion of the optical fiber 6. It is.

In addition, if the holder main body 1 with the optical fiber 6 inserted into the small hole 2 is fixed with the tearing line 3 side facing the fixing surface such as the floor or wall surface where the wiring is to be wired, as shown in FIG. The effect of preventing dust from entering can be further improved.

Furthermore, the tabs 7 formed on both sides (or one side) of the holder main body 1 expand the fixing area and provide stable fixing action when fixing the holder main body 1. There is a craft that makes it possible to use it. When this ear piece 7 is formed, in the round wiring part, the ear piece 7 on the inside of the round is removed as shown in FIG. 5, or the ear piece 7 on the inside of the round is removed as shown in FIG. A slit 9 is provided in the ear piece 7 of the holder to allow the holder body 1 to bend.

As described above, according to the present invention, in the original fiber wiring provided with at least two or more protective coatings,
Since the optical fiber is protected by a synthetic resin holder held in a small hole, the external pressure screw prevents the optical fiber from being cut or the protective coating from being damaged due to contact with other objects, as well as preventing damage from moisture, dust, etc. It has the effect of being long-lasting and making wiring work of fine optical fibers much easier.

Moreover, the optical fiber can be pushed into the narrow hole of the holder main body quickly and reliably by manual pushing as well as mechanical pushing due to the guiding action of the four V-shaped parts.

Furthermore, the tabs on both sides (or one side) of the holder body make the wire fixing work of the holder body easier and more reliable, and maintain a stable fixing state.

In addition, in the case of a continuum of multiple sets of at least two small holes, wiring for multiple lines can be obtained at once, and at least two holes can be made by tearing and separating the connected parts. It has many advantages such as being able to be used as a single wiring set, and will be extremely effective and practical for optical fiber wiring that will be commonly used in the future.
