Abstract

The invention relates to a fiber optic sheath, and aims to provide a fiber optical sheath with better torsional effect. The fiber optic sheath comprises a tubular casing, wherein two ends of the casing are opened, ribs with preset flexibility are arranged between the inner and outer walls of the casing and extend along the axial direction of the casing; the inner wall and the outer wall of the casing are frosted surfaces. The fiber optic sheath has the beneficial effects of being not easy to break or fracture, better in torsional effect, and suitable for being applied and popularized.

Description

Optical fiber jacket

Technical field

The present invention relates to a kind of optical fiber protecting equipment, relate in particular to a kind of optical fiber jacket.

Background technology

Modern cars spray-painting production line is all to adopt automatic spraying machine, and optical fiber is for transmitting run signal and the feedback signal of automatic spraying machine.Optical fiber cable is afraid of bending and torsion most, and is omnibearing when vehicle spray painting, and flush coater arm drives the optical fiber just must rotoflector operation, like that just be easy to cause optical fiber to fracture or jackknifing, affect the signal transmission of spray robot, robot can not be moved, cause off-production.This accident occurs in the past, was all to stop the optical fiber that line more renews, expense and height, and one new wants more than 5000 yuan, renews optical fiber with more than 80 minutes.

Chinese patent notification number CN1567010A discloses a kind of fiber boot; comprise a protective sleeve body and a resilient ring; protective sleeve body is coupled in optical fiber and the collar; resilient ring is installed between the outside and protective sleeve body of the collar; resilient ring utilizes thermosetting sticker to be adhered on protective sleeve body; fiber boot also comprises posterior limiting, between protective sleeve body and thermosetting sticker.The antitorque poor effect of this fiber boot.

China Patent Publication No. CN101251630A discloses a kind of ferrule of optical fiber head, and optical fiber head comprises optical fiber cable and ferrule, and the tail end of optical fiber cable is encapsulated in the endoporus of ferrule, and wherein ferrule is porcelain bushing.This ferrule, without pliability, is not suitable for above-mentioned vehicle spray painting production line.

Summary of the invention

The object of the present invention is to provide the good optical fiber jacket of a kind of antitorque effect, to solve the problem existing in background technology.

To achieve these goals, technical scheme of the present invention is: a kind of optical fiber jacket, comprises the sleeve pipe of tubulose, the both ends open of this sleeve pipe, the muscle that is provided with default suppleness between the inside and outside wall of described sleeve pipe, muscle extends axially along sleeve pipe, and the inside and outside wall of described sleeve pipe is frosting.The design philosophy of this technical scheme is: optical fiber is inserted in sleeve pipe, sleeve pipe inserts in the external shroud of optical fiber again, sticking with glue between any two, the muscle of default suppleness guarantees that optical fiber jacket can not bend fracture, the frosting of the inside and outside wall of sleeve pipe can increase and optical fiber, the adhesion of external shroud, shearing resistance, this optical fiber jacket is frangibility or jackknifing not, and antitorque effect is better.

As preferably, between the inside and outside wall of described sleeve pipe, be provided with several muscle, several muscle are circumferentially uniform sleeve pipe.Several muscle can provide and strengthen antitorque effect in the circumferential multiple directions of sleeve pipe.

As preferably, described muscle has three.Three uniform muscle are firm triangular structure, cost-saving under the prerequisite that meets intensity.

As preferably, the outer wall of described sleeve pipe is provided with three grooves, and the length direction of groove extends axially along sleeve pipe.Article three, in groove, both can fill the use of sticker, the limit, two outers of each groove can increase again twisting resistance.

As preferably, described three grooves are circumferentially uniform sleeve pipe.

As preferably, described three grooves are located at respectively the centre position of two muscle.

As preferably, described groove is deep-slotted chip breaker.Above three are intended to make groove distribution more reasonable, and stress distribution is more even.

As preferably, described sleeve pipe has several sections of base segments, and described sleeve pipe is connected in sequence by several sections of base segments head and the tail.This has two objects: the one, and as long in optical fiber, wear sleeve pipe operation and be difficult for, be divided into several sections of base segments, cross-under piecemeal, easy and simple to handle; The 2nd, in the situation that not needing whole piece optical fiber all to wear sheath, can install one additional to several sections of base segments rocking the position that more frequent amplitude is larger, can play equally the effect of protection optical fiber.

As preferably, one end of described base segment has outwards outstanding hook structure, and the other end of base segment has inwardly recessed bayonet arrangement, described hook structure and bayonet arrangement adaptation.Base segment takes negative and positive buckle structure to insert connection.

As preferably, the length of described base segment is 18～20mm.

The beneficial effect of optical fiber jacket of the present invention is: this optical fiber jacket is frangibility or jackknifing not, and antitorque effect is better.
