Abstract

Disclosed in the utility model is an optical fiber heating joint that comprises an optical fiber contraction clamp sleeve, an optical fiber ferrule, an SC inner sheath with two ends opened, an SC outer sheath, and a compaction sleeve. The SC inner sheath is sleeved outside the optical fiber ferrule and the SC outer sheath is movably clamped outside of the SC inner sheath. The front end of the optical fiber ferrule is stretched into the hollow tail sleeve of the optical fiber contraction clamp sleeve; the SC outer sheath is clamped tightly outside the optical fiber contraction clamp sleeve; and the compaction sleeve and the conical head of the optical fiber contraction clamp sleeve are in a screw-thread fit and the optical fiber is clamped inside the conical head. According to the utility model, the joint has advantages of simple and compact structure as well as low production cost; the design that the SC outer sheath is used to clamp the optical fiber contraction clamp sleeve is utilized, thereby effectively preventing the occurrence of the bending phenomenon and ensuring the security of the optical fiber connection operation. Meanwhile, the holding operation of the optical fiber can be carried out conveniently; the good communication performance is realized; and the connection loss can be effectively reduced.

Description

A kind of optical fiber hot joint

Technical field

The utility model designs a kind of joints of optical fibre, is specially a kind of optical fiber hot joint.

Background technology

The joints of optical fibre are used in Fiber Optical Communication System between the fiber optic cable, connecting between this fiber optic cable and the optoelectronic components and between this optoelectronic components.For example, utilize Optical fiber plug to connect fiber optic cable.Fiber Optical Communication System can be used the optical fiber or the multi-mode optical fiber of monotype.The joints of optical fibre link together the core of these optical fiber, thus make luminous energy from a spread fiber to another optical fiber.Traditional joints of optical fibre can guarantee that fiber core can repeatedly aim at, but it bends in use easily, influence the operation of accommodating of optical fiber, make troubles to the user.

The utility model content

The purpose of the utility model provides a kind of optical fiber hot joint, and traditional joints of optical fibre bend in use easily in the prior art to solve, the problem of making troubles to the user.

For achieving the above object, the technical scheme that the utility model adopts is:

A kind of optical fiber hot joint; It is characterized in that: include SC inner sheath, SC oversheath and clamping sleeve that optical fiber shrinks chuck, fiber stub, both ends open, the front end that said optical fiber shrinks chuck is the hollow taper head that has the slit, and the rear end is a hollow tail cover; Be packaged with short fiber through bonding agent in the said fiber stub; Said short fiber runs through fiber stub, and said fiber stub rear end is movably installed with the ceramic insertion core protective sleeve, and said SC inner sheath is sleeved on outside the fiber stub; Said SC oversheath active card is connected on outside the SC inner sheath; The front end of said fiber stub stretches in the hollow tail cover of optical fiber contraction chuck, and said SC oversheath is clamped on optical fiber and shrinks outside the chuck, and the conical head of said clamping sleeve and optical fiber contraction chuck is through threaded engagement and make fiber gripper in conical head.

Described a kind of optical fiber hot joint is characterized in that: be provided with block in the said SC oversheath front end, said fiber stub rear end outwards is provided with base, is provided with spring between block in the said SC oversheath and the base outside the fiber stub.

The beneficial effect of the utility model is:

The utility model is simple in structure, compact; Production cost is low, and the design of adopting SC oversheath chucking optical fiber to shrink chuck can effectively prevent the generation of buckling problem; Guaranteed the security of optical fiber attended operation; Help the operation of accommodating of optical fiber simultaneously, have good communication performance, effectively reduce junction loss.
