Abstract

The utility model discloses a movable bushing type fiber jumper wire suitable for a fiber communication system, a fiber sensor, a fiber instrument, a local area network, a wide area network, a network broadband, and Fiber To The Home. A positioning bushing (4) is in a plugging in a tail handle (5), and is movably connected to an inner frame bushing (3). The inner frame bushing (3) is connected to an adjustable bushing (2) via screw threads, is movably disposed in an outer bushing (1), and is movably controlled by a separating ring (8) in the outer bushing (1). A fiber sheath (7) wraps fibers, and is disposed at the left inner end of the adjustable bushing (2). The fiber jumper wire is advantageous in that, the outer bushing and the fiber inner bushing are movably connected and are used for effectively controlling the length of a jumper wire, thereby reducing plugging loss of connecting devices. Return loss is high, and protection effect is provided. The fiber jumper wire is also advantaged by compact structure, simple application, reduction of device size, low cost, high reliability, and achievement of plug-and-play.

Description

Movable sleeve tubular type optical patchcord

Technical field: the utility model relate to a kind of be applicable to Fiber Optical Communication System, Fibre Optical Sensor, fiber instrument instrument, LAN (Local Area Network) and wide area network, network broadband and Fiber to the home use movable sleeve tubular type optical patchcord.

Background technology: what the syndeton of existing conventional optical cable jumper adopted is mostly plug-in type, in the direct insertion of connection, can apply, advantage is plug and play, its shortcoming one is that the frequent use of plug-in type easily causes wearing and tearing, has shortened serviceable life, the 2nd, and plug-in type is fixed form, can not regulate, usable range is dwindled greatly, and easily produces the problem that optical fiber micro-bending causes loss to increase in installation process and use procedure, and the insulativity of junction also exists defect.

Utility model content: the purpose of this utility model is to overcome the drawback that current use optical patchcord exists, and provides one to reduce jumper coupler part volume and Insertion Loss, simple in structure, application mode is simple and direct.The high movable sleeve tubular type optical patchcord using of reliability.

The technical scheme that the utility model taked is for achieving the above object: its locating sleeve 4 is plugged in caudal peduncle 5, and with inside casing sleeve pipe 3 is flexibly connected, inside casing sleeve pipe 3 is threaded connection adjusting sleeve pipe 2, and be movably placed in outer tube 1, and by movable control of spacer ring 8 in outer tube 1, optical fiber jacket 7 wraps up optical fiber, and is placed in the left inside end of adjusting sleeve pipe 2.

The beneficial effects of the utility model are: owing to adopting outer tube and optical fiber inner sleeve to be flexibly connected and the wire jumper length that control effectively; by fiber splicer, directly dock and carry out optically-coupled; the Insertion Loss that has reduced interface unit, return loss is high, plays protection effect.And compact conformation, application mode is simple and direct.Save device volume, with low cost, there is higher reliability, and can realize plug and play.

Accompanying drawing explanation: Fig. 1 is structural representation of the present utility model

Fig. 2 is the cut-open view of Fig. 1

Embodiment: as shown in Figure 1 and Figure 2, its locating sleeve 4 is plugged in caudal peduncle 5, and with inside casing sleeve pipe 3 is flexibly connected, inside casing sleeve pipe 3 is threaded connection adjusting sleeve pipe 2, and be movably placed in outer tube 1, and by movable control of spacer ring 8 in outer tube 1, optical fiber jacket 7 wraps up optical fiber, and is placed in the left inside end of adjusting sleeve pipe 2.

As shown in Figure 1 and Figure 2, the described left inside end of outer tube 1 arranges lock pin 6, and optical fiber is fixedly connected on the interior middle part of lock pin 6, and the front end of lock pin 6 arranges optical fiber helmet 9.
