Abstract

The utility model relates to a fiber connection unit, a fiber connection device and a fiber cold connector. The fiber connection unit includes a ceramic rod serving as a base. The center of the ceramic rod is provided with a central through hole. The middle segment of the ceramic rod is provided with a radial hole which enables the central through hole to communicate with the outside. The advantages are that: the ceramic rod which is provided with the central hole replaces a V-shaped groove in a conventional structure, and serves as the fiber connection unit, so the material stability is excellent, the deformation is not easy to occur, and the butt joint positioning precision and the success rate are high; and because the ceramic rod can be produced through arranging the radial hole on a conventional fiber device, i.e. a ceramic pin, the manufacturing process is mature, the processing is convenient, and the manufacturing cost is low.

Description

The optical fiber linkage unit and the joints of optical fibre and optical fiber cold junction

Technical field

The utility model relates to optical fiber linkage unit and the joints of optical fibre and optical fiber cold junction.

Background technology

For the butt joint of two optical fiber, adopt quick coupler or optical fiber cold junction to connect traditionally.These two kinds of connected modes are except the shell structure difference, and the linkage unit structural principle of its core is basic identical, and the V groove part that all utilizes plastics or metal material positions butt joint to the end of two sections optical fiber.In this structure, as the V groove of linkage unit, its difficulty of processing is big, and machining precision is difficult for guaranteeing that influence structure precision easily because of material is yielding, optical fiber locating accuracy in the V groove is not high yet, and these factors all can cause the decline of butt joint quality.In addition, in the existing said structure, quick coupler or optical fiber cold junction after optical fiber connects are difficult to through shirtsleeve operation its quality of connection detected, for follow-up test and use are made troubles.

Summary of the invention

The utility model technical matters to be solved provides and a kind ofly connects precision and connect into power height, optical fiber linkage unit easy to process and the joints of optical fibre and optical fiber cold junction.

The optical fiber linkage unit of the utility model includes a ceramic rod as matrix, has the center pit that front and back connect at the center of ceramic rod, and the stage casing of ceramic rod has a radial hole that makes center pit and exterior.

The diameter of said center pit is than the big 0～0.001mm of fibre diameter to be connected.

Said center pit one end is set to tapered opening.

The optical fiber splicing device of the utility model can be the joints of optical fibre or optical fiber cold junction.

The joints of optical fibre of the utility model are made up of a connector shell and an above-mentioned optical fiber linkage unit; Said connector shell is made up of the cable sheath that connects successively, optical fiber cover and adapter sleeve; The part of said optical fiber linkage unit is inserted in the adapter sleeve, have on the adapter sleeve one with the optical fiber linkage unit on the relative view window of radial hole.

Optical fiber cold junction of the utility model includes upper shell and the lower house that is involutory; The cavity of side formation within it after upper shell and lower house are involutory; Said optical fiber linkage unit is placed in the cavity that the involutory back of upper shell and lower house forms, have on upper shell or the lower house with the optical fiber linkage unit on the relative viewport of radial hole.

The utility model has the advantages that: replace V groove in the traditional structure as the optical fiber linkage unit with the ceramic rod of band center pit, its stability of material is good, not yielding, butt joint bearing accuracy and success ratio are high; Form owing to ceramic rod can increase radial hole on the basis of traditional fiber device-ceramic contact pin, its manufacturing process is ripe, easy to process, low cost of manufacture.

Embodiment

As shown in Figure 1, the optical fiber linkage unit 1 of the utility model has a ceramic rod 11 as matrix, has the center pit 12 that front and back connect at the center of ceramic rod, and the stage casing of ceramic rod has a radial hole 13 that makes center pit and exterior.The diameter of center pit is than the big 0～0.001mm of fibre diameter to be connected.Center pit one end is set to tapered opening 14.The ceramic rod that has center pit can utilize the equipment and the technology manufacturing of existing processing ceramic contact pin.

The optical fiber splicing device of the utility model can be the joints of optical fibre or optical fiber cold junction that adopts above-mentioned optical fiber linkage unit.

As shown in Figure 2, the joints of optical fibre of the utility model are made up of a connector shell 2 and an above-mentioned optical fiber linkage unit 1, and said connector shell is made up of the cable sheath 21 that connects successively, optical fiber cover 22 and adapter sleeve 23; The part of optical fiber linkage unit 1 is inserted in the adapter sleeve 23, have on the adapter sleeve 23 one with the optical fiber linkage unit on the relative view window 24 of radial hole 13.Optical cable is inserted by the cable sheath end in the joints of optical fibre use, and the optical fiber that stretches out in the optical cable passes the center pit that gets into adapter sleeve behind the center pit of optical fiber cover and insert the optical fiber linkage unit, the fiber alignment that inserts with the optical fiber linkage unit other end.

Optical fiber cold junction of the utility model includes the upper shell 31 and lower house 32 that is involutory; The cavity of side formation within it after upper shell and lower house are involutory; Above-mentioned optical fiber linkage unit 1 is placed in the cavity that upper shell and the involutory back of lower house form, have on upper shell or the lower house with the optical fiber linkage unit on the relative viewport 33 of radial hole 13.

In the optical fiber connection side unit use of the utility model, an optical fiber is inserted from center pit 12 1 ends of ceramic rod 11, its end extend into radial hole 13 right position; With coupling cream from radial hole be injected into radial hole and radial hole in right one section center pit; With other bar optical fiber from the center pit other end of ceramic rod insert and with the fiber alignment of opposite side, part coupling cream is overflowed from radial hole, accomplish butt joint.

After adopting said method to accomplish butt joint,, observe docking point, leak, explain that butt joint is unsuccessful, otherwise then dock successfully if can in radial hole, observe light from radial hole from an outer fiber end input light source.
