Abstract

The utility model discloses an optical fiber protection structure for an optical fiber connector. The optical fiber protection structure comprises a ceramic inserting core, a tail handle and a V-shaped sleeve, wherein the ceramic inserting core is fixedly installed at one end of the tail handle, the V-shaped sleeve is connected at the other end of the ceramic inserting core, a precast bare optical fiber is arranged in the ceramic inserting core, the front end of the precast bare optical fiber is arranged in a V-shaped groove of the V-shaped sleeve, an elastic sponge body is also arranged in the V-shaped groove of the V-shaped sleeve, and the front end of the precast bare optical fiber is arranged under the elastic sponge body. In the optical fiber protection structure, the elastic sponge body is arranged in the V-shaped sleeve, and the precast bare optical fiber and a butted optical fiber are arranged under the elastic sponge body, so that when the optical fibers are butted, the pressing-down force of a movable pressing plate can be transmitted by the elastic sponge body so as to increase the stress area of the butting part, and the purpose of protecting the optical fibers from being pressed and broken is achieved.

Description

Joints of optical fibre optical fiber safeguard structure

Technical field:

The utility model relates to the joints of optical fibre, particularly a kind of joints of optical fibre optical fiber safeguard structure.

Background technology:

The joints of optical fibre; Be optical fiber with optical fiber between carry out the device that detachable (activity) is connected; It gets up the accurate butt joint of two end faces of optical fiber; Go so that the luminous energy of launching fiber output can be coupled to receive in the optical fiber to greatest extent, thereby and make its intervention optical link reduce to minimum the influence that system causes.

In the fiber alignment process, for guaranteeing good transmission performance, must guarantee the precision of fiber alignment position, be fixed and clamped and after butt joint, need to dock optical fiber usually, because the singularity of optical fiber the situation that optical fiber is pressed down occurs through regular meeting.

The utility model content:

For this reason, the purpose of the utility model is to provide a kind of joints of optical fibre optical fiber safeguard structure, to avoid the situation that optical fiber is pressed down occurring when the fiber alignment.

For realizing above-mentioned purpose, the utility model mainly adopts following technical scheme:

A kind of joints of optical fibre optical fiber safeguard structure; Comprise ceramic insertion core (1), caudal peduncle (2) and V-arrangement cover (11), said caudal peduncle (2) one ends are installed with ceramic insertion core (1), and the other end is connected with V-arrangement cover (11); Be provided with pre-buried bare fibre (8) in the said ceramic insertion core (1); This pre-buried bare fibre (8) front end is arranged in the V-shaped groove of V-arrangement cover (11), also is provided with an elastic sponge body (4) in the V-shaped groove of said V-arrangement cover (11), and the front end of above-mentioned pre-buried bare fibre (8) is positioned at this elastic sponge body (4) below.

Also be provided with a movable pressing board (3) on the wherein said elastic sponge body (4).

Be adsorbed with optical fiber matching fluid in the wherein said elastic sponge body (4).

The utility model is through being provided with an elastic sponge body in V-shaped groove; And pre-buried bare fibre with dock optical fiber and be positioned at this elastic sponge body below; When optical fiber is docked; The power that movable pressing board presses down can be conducted through the elastic sponge body, makes the lifting surface area of docking location become big, thereby reaches the purpose that protection optical fiber is not pressed down.

Description of drawings:

Fig. 1 is the structural representation of the utility model joints of optical fibre.

Fig. 2 is an A-A cut-open view among Fig. 1.

Identifier declaration among the figure: ceramic insertion core 1, caudal peduncle 2, movable pressing board 3, elastic sponge body 4, optical fiber tightly overlap 5, fixedly tapered sleeve 6, flexible bare fibre 7, pre-buried bare fibre 8, rotating shaft 9, butt joint optical fiber 10, V-arrangement overlap 11.

Embodiment:

For setting forth the thought and the purpose of the utility model, will combine accompanying drawing and specific embodiment that the utility model is done further description below.

See also Fig. 1, shown in Figure 2, Fig. 1 is the structural representation of the pre-buried optical fiber quick connector of the utility model; Fig. 2 is an A-A cut-open view among Fig. 1.

The described pre-buried optical fiber quick connector of the utility model includes ceramic insertion core 1, caudal peduncle 2 and V-arrangement cover 11; Said caudal peduncle 2 one ends are installed with ceramic insertion core 1; The other end is connected with V-arrangement cover 11 through rotating shaft 9, is provided with pre-buried bare fibre 8 in the said ceramic insertion core 1, and the front end of said pre-buried bare fibre 8 is arranged in the V-shaped groove of V-arrangement cover 11; Also be provided with an elastic sponge body 4 in the V-shaped groove of said V-arrangement cover 11, the front end of above-mentioned pre-buried bare fibre 8 is positioned at this elastic sponge body 4 belows.

The outside of flexible bare fibre 7 is the tight cover 5 of optical fiber, and inner core is butt joint optical fiber 10, the corresponding below that all is positioned at elastic sponge body 4 of front end of said butt joint optical fiber 10 and above-mentioned pre-buried bare fibre 8.

Movable pressing board 3 is arranged in the top of V-shaped groove elasticity cavernous body 4, and the V-shaped groove rear end of its rear end and V-arrangement cover 11 flexibly connects through bearing pin, and front end is then fixed through being positioned at the fixedly tapered sleeve 6 that V-arrangement overlaps 11 outsides.

Butt joint optical fiber 10 inserts and pre-buried bare fibre 8 contrapositions through V-shaped groove; This moment, elastic sponge body 4 was positioned at above-mentioned butt joint optical fiber 10, pre-buried bare fibre 8 tops; Push movable pressing board 3, elastic sponge body 4 is fixed the optical fiber contact, and also be adsorbed with matching fluid in the elastic sponge body 4 here; Extruding flows to the docking point place of butt joint optical fiber 10 and pre-buried bare fibre 8, can reduce the junction loss of optical fiber.
