Description
Technical field
It is specifically a kind of based on high power single mode guarantor/mono- special optical fiber partially the present invention relates to high power light fiber connector
Moisture seal type connector.
Background technique
Conventional single-mode guarantor/single polarization fiber connector is assembled by each standard parts and components, and forming process does not seal work
Skill does not do moisture seal processing yet, in practical applications, especially long-term application on site when, conventional fiber optic connectors do not have
Moisture seal effect causes its internal moist and cleanliness not up to standard, brings seriously in optical transport, light measurement, light sensing field
In consequence, especially device of high power laser or strong optical transport and measurement application, main laser transmission is measured to used light
Not only quantity is more and new requirement is proposed to optical fiber connector for fiber connector, in this kind of focus on the application field, since optical fiber connects
It is higher to connect optical power in device, generates heat in optical fiber connector docking, when optical path disconnects, restores room temperature in optical fiber connector
In the process, being generated at water mist, especially optical fiber connector docking in has water mist condensation, leads to device of high power laser and Qiang Guang
Transmission with measuring system light loss increase, performance degradation, in addition the fibre core of optical fiber connector can be damaged and influence device and
The normal use of system analyzes its reason, and mainly conventional single-mode guarantor/single polarization fiber connector moisture seal performance is poor, specifically
It is because conventional single-mode guarantor/single polarization fiber connector makes forming process and do not do moisture seal processing when docking use with flange
Technique causes micronic dust and steam in air to enter the ferrule endface and surrounding of fiber alignment.
Summary of the invention
The purpose of the present invention is in view of the deficiencies of the prior art, and provide a kind of based on high power single mode guarantor/mono- special type partially
The moisture seal type connector of optical fiber.This New connector is because extra cost produced by technological innovation and process modification is low, tool
There are the advantages of moisture-proof and good seal performance, manufacture craft simple and be not required to change the structure size of original each components, using model
It encloses wide, is a kind of high stable connection, service life long optical passive component.
Realizing the technical solution of the object of the invention is:
A kind of moisture seal type connector based on high power single mode guarantor/mono- special optical fiber partially, including by standarized component flange, the right side

The silicone rubber is DOWCORNING732 sealant, and DOWCORNING732 sealant at least viscose glue covers annulus
Left side outer surface, stop caudal peduncle left-half outer surface and compress at the connection gap of ring outer surface, after viscose glue is dry, tail
Fiber coating pipe can normally be locked.
It is this that silica gel ring sealing technology is used based on high power single mode guarantor/mono- special optical fiber partially moisture seal type connector
Technology and silicone rubber viscose glue sealing technology utilize the reserved space between each part-subassemble standard part connection of conventional fiber optic connectors
Silicone rubber adhering process at silica gel ring Encapsulation technology and 1 at gap newly-increased 3, and reliably connected by the fastening of each components
It connects, guarantees that the connector of the technical program has good moisture seal when in use.
This new moisture seal type high power single mode guarantor/mono- special optical fiber connector partially can overcome conventional single-mode guarantor/mono-
The shortcomings that when polarisation fiber connector and its use, specific beneficial effect mainly has the following:
1) can prolonged application in the optical transport and light measurement of high-power fiber device or system, have moisture seal steady in a long-term
Performance solves the problems, such as that conventional single-mode guarantor/single polarization fiber connector moisture seal is poor；
2) conventional single-mode guarantor/single polarization fiber connector and its application can be directly substituted, do not need separately to set interface or is restructured；
3) this moisture seal type high power single mode guarantor/mono- special optical fiber connector partially is still to be flexibly connected with flanged joint,
It can arbitrarily be plugged when use, connection has long-term moisture seal effect when fastening；
4) cost of this moisture seal type high power single mode guarantor/mono- special optical fiber connector partially is low, surface structure size not
Become, manufacture craft and step are simple, have a wide range of application, market capacity is big；
5) this moisture seal type high power single mode guarantor/mono- special optical fiber connector partially does not increase because of newly-increased moisture seal technique
Add the added losses of optical fiber connector, which does not influence end face when guarantor/single polarization fiber connector production
Milled processed technique and to axis precision, optical index is not influenced by newly-increased technique after molding.
This connector because extra cost caused by newly-increased moisture seal is low, with moisture-proof excellent with good seal performance
Point, manufacture craft are simple, have a wide range of application, and are a kind of high stable connection, service life long optical passive component.
