Abstract
The utility model relates to a large diameter ratio capillary glass tube joint. The ratio of the outer diameter and the inner diameter of a capillary glass tube is more than five. A tube core forms a conical interface at the end part. The tube core is smoothly connected with the conical interface. A generating line at the lateral surface of a cone of the conical interface comprises at least one section of smooth curved line. At least one section of smooth curved line and at least one section of straight line are smoothly connected to form the utility model; or a curved line, a straight line, a curved line and a straight line are alternate to be smoothly connected to form the utility model. The utility model solves the problem that when optical fiber and a capillary quartz tube are inserted in the capillary glass tube joint, too much insertion loss is generated. The utility model can satisfy the requirement of using the rationalized performance of a glass body. The utility model has good environmental stability. The dimensional precision of the utility model can reach a micron order, which can lead the optical fiber and a quartz fiber tube to be connected end to end through the joint. The utility model is suitable for an optical fiber instrument, an optical active device, an Optical fiber array, an optical fiber sensor and a bioengineering instrument.
Description
Technical field

Background technique
Glass devices and manufacturing technology thereof are widely used in optical communication equipment, bioengineering instrument, electronic device and the laser device.Along with popularizing of Internet, the frequency range demand increases fast, brought up the wide growing space of international optical communication industry, especially after the each department fixed network is open, optical fiber has become the important transmission medium of communication network, at present about in the world communication traffic of 60% to 80% is through Optical Fiber Transmission, and the glass tube joint that is used to connect optical fiber is widely used.Equally, in the bioengineering industry,, in the collection of biological products, transfer, transportation, manufacturing, adopted widely and had certain irreplaceability because glass has special chemical stability.Existing large diameter-ratio capillary glass tube joint, the external diameter of glass tube and the ratio of internal diameter are greater than five, tube core is conical interface in the end, conical interface is made for polishing cold working, the bus of its cone side is a straight line, because of surface smoothness is lower, when brittle material inserts and passes through, the insertion loss is higher, can not satisfy optical fibre head, the connection of capillary tube highi degree of accuracy.
Technology contents
The utility model will solve that the such brittle material of optical fiber, capillary quartz tube inserts and during by the large diameter-ratio capillary glass tube joint, insert the too high technical problem of loss.
The technological scheme of the utility model large diameter-ratio capillary glass tube joint: the external diameter of capillary glass tube and the ratio of internal diameter are greater than five, tube core is conical interface in the end, it is characterized in that: its tube core is connected with conical interface smooth, and the cone side bus of its conical interface comprises one section level and smooth curve at least.
The cone side bus of above-mentioned conical interface is to be formed by at least one section level and smooth curve and at least one section straight line smooth connection.
The cone side bus of above-mentioned conical interface is to be formed by the smooth connection separately of curve-straight line-curve-straight line.
Above-mentioned interface outside can be connected with metallo-plastic rubber or be fixed by it.
Above-mentioned capillary glass tube is water white transparency body, colored transparent body or translucent body.
The external diameter of above-mentioned capillary glass tube is the consistent or reducing of sizing with the external diameter of conical interface section.
Beneficial effect: the utility model large diameter-ratio capillary glass tube joint at one end or two ends have level and smooth conical interface to its inwall.Make object by this joint, as optical fiber, the such brittle material of capillary quartz tube insert and by the time do not sustain damage i.e. low insertion loss.Low insertion loss is that fiber products is in the important technology index of producing in installing.Protection connection simultaneously and the object that passes through are not damaged under the physical and chemical index that its pipe joint reaches.Because level and smooth conical interface structure has been arranged, easy and simple to handle in use, labor intensity reduces, and productivity improves.Characteristics are: 1) satisfy the requirement of using the vitreous humor physicochemical property.2) has good environmental stability.3) be inserted into and junction loss.4) reach micron-sized dimensional accuracy and can make as optical fiber, the quartz fibre pipe achieves a butt joint through this joint.Can be applied to fiber instrument, optical active component, fiber array, optical fiber transducer and bioengineering instrument.
