Abstract
The invention discloses a single-core optical fiber cold connector comprising a cold connector body composed of a first body and a second body. Optical fiber cable grooves for containing optical fibers are formed in the adjacent faces of the first body and the second body. The middles of the optical fiber cable grooves are wider that the two ends of the optical fiber cable grooves. The two outer sides of the first body and the second body are provided with protrusions respectively. An elastic cap is rotationally connected through the cold connector body through rotating holes and the protrusions. The elastic cap is in a right-angled n shape. When pressed down, the elastic cap compresses the first body and the second body. The single-core optical fiber cold connector has the advantages that an optical fiber connecting thin pipe with ultrahigh precision is adopted, and the optical fiber center autocollimation technology is adopted, so that ultrahigh collimation precision is kept when two optical fibers are connected; the average optical fiber connection loss is 0.15 dB.
Description
Technical field
The present invention relates to fiber cabling device, particularly fibre-optical splice.
Background technology
As Fiber connection, along with the optical link high speed Internet access spread in recent years, more and more need a connection, traditional coupling arrangement complex structure, inconvenient operation, many defects such as production cost is high.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of novel single-core fiber cold connector.
To achieve these goals, the technical solution used in the present invention is:
Single-core fiber cold connector, the body be made up of the first noumenon and the second body, the face that the first noumenon is adjacent with the second body is all provided with the Fibre-optical slot of receiving optical fiber, and Fibre-optical slot middle part is wider than two ends, the first noumenon and the second body two outside be respectively equipped with projection, spring caps is by rotation hole and be protrudingly rotatedly connected with body, and spring caps is a few font, when spring caps is depressed, the first noumenon is compressed mutually with the second body.
On described the first noumenon, inner side is provided with connection bump, and the second described body is provided with shrinkage pool, and the first noumenon is connected with shrinkage pool close-fitting by connection bump with the second body.
The position that the first noumenon contacts with spring caps with the lateral surface of the second body is provided with multiple transverse concave groove.
Beneficial effect of the present invention: the Fiber connection tubule adopting superhigh precision; Have employed fiber optic hub self-aligned technology, make to keep high alignment precision during two fibre junctions; The average connecting loss of optical fiber connector is 0.15dB, even if (without fine alignment) its loss that arbitrarily continues also is easy to reach below 0.4dB.It can be applied in 250/250 μm, 250/900 μm, or the occasion of 900/900 μm of fibre junction, without the need to bonding agent and epoxy glue, highly versatile, optical fiber without the need to grinding, fiber optic hub autoregistration, optional 900 μm of optic fibre guide protection tubes.Can intense adjustment, alignment area optical fiber is unstressed; Meet industry to continue standard; Thermal stability ensures normal work in-40 to 80 degree Celsius range.

Embodiment
Refer to accompanying drawing and its implementation process is described: single-core fiber cold connector, the body 1 be made up of the first noumenon 11 and the second body 12, the face that the first noumenon 11 is adjacent with the second body 12 is all provided with the Fibre-optical slot 122 of receiving optical fiber, and Fibre-optical slot 122 middle part is wider than two ends, the first noumenon 11 and the second body 12 two outside be respectively equipped with protruding 111, spring caps 2 is rotatedly connected with body 1 by rotation hole 21 and protruding 111, spring caps 2 is a few font, when spring caps 2 is depressed, the first noumenon 11 is compressed mutually with the second body 12.
On described the first noumenon 11, inner side is provided with connection bump 121, and the second described body 12 is provided with shrinkage pool 123, and the first noumenon 11 is connected with shrinkage pool 123 close-fitting by connection bump 121 with the second body 12.
The position that the first noumenon 11 contacts with spring caps 2 with the lateral surface of the second body 12 is provided with multiple transverse concave groove.During use, be placed on by optical fiber between two bodies, fibre-optical splice position is placed in middle wide groove, and two bodies are connected with the close-fitting of shrinkage pool 123 by connection bump 121.Then the rotation hole 21 of spring caps 2 is stuck on protruding 111, has two symmetrical spring caps 2 to be oppositely arranged.Two bodies just can press together by pressure spring caps 2, so just optical fiber can be pressed together within body tightly.
Optical fiber connector uses very simple, does not have too many annex, needs training hardly.Operation steps is: fiber stripping is also good fiber cut, and will the optical fiber continued be needed to insert in connector respectively, until they contact with each other, then two ends buckle compresses and protects optical fiber, without the need to any cementing agent or other specific purpose tool in this process.The fibre junction in compact structure generous 30 seconds; Can work under circumstances.Be suitable for optical cable scope wide, be applicable to corridor distributing cabinet (FDU) fibre junction, the continuing of covered wire cable and tail optical fiber in Multi-media box, repair the circuit that damages to realize fibre junction firmly, reliably.Be applicable to continuing of any single core multimode and single-core fiber, simple operation, quick, safe and reliable.Can be used for that FTTH (fiber to the home) tail optical fiber continues, the switching of dissimilar optical cable, the access of unification of three nets terminal, install in such as optical fiber information panel.
