Abstract
The utility model proposes a kind of high-power laser optical fiber adapter, can effectively fix optical fiber, it is to avoid power loss when causing high-power laser optical fiber to couple because of the vibration of coupling object.In the high-power laser optical fiber adapter, a tail pipe is fixedly connected with by sleeve pipe also in the port of export of the lock pin；The tail pipe through, and with lock pin inside axial channel and sleeve pipe it is coaxial, connect the high-power laser optical fiber for wearing；High-power laser optical fiber is relatively fixed in tail pipe.By increasing a tail pipe so that be divided into two sections of isolation to the fastening effect of optical fiber, therefore the tightening effect of optical fiber is substantially better than traditional structure.For example, when overall structure is in design than traditional size to the youthful and the elderly 1/3rd (tail pipe position), power of the optical fiber in transmission apparatuss dynamic change floats less than 5%.
Description
Technical field：
This utility model is related to a kind of high-power laser optical fiber adapter.
Background technology：
The common joints of optical fibre mainly using being formed directly into, three grab cassette and the mode such as penetrate, insert optical fibers into stainless
In lock pin made by steel or ceramic material (i.e. optical fiber is located at the axial channel of lock pin), and using epoxy glue bonding way processing system
Make the joints of optical fibre.
Due to traditional joints of optical fibre merely with lock pin and epoxy glue fixing optical fiber so that the fixed effect of optical fiber is very
Undesirable, power when further resulting in transmission apparatuss dynamic change floats more than 10%.
Utility model content：
The utility model proposes a kind of high-power laser optical fiber adapter, can effectively fix optical fiber, it is to avoid because of coupling
The power loss when vibration of object causes high-power laser optical fiber to couple.
Solution of the present utility model is as follows：
A kind of high-power laser optical fiber adapter, including the lock pin for installation positioning optical fiber, it is characterised in that：Insert at this
The port of export of core is also fixedly connected with a tail pipe by sleeve pipe；The tail pipe through, and with lock pin inside axial channel
And sleeve pipe is coaxial, connects the high-power laser optical fiber for wearing；High-power laser optical fiber is relatively fixed in tail pipe.
Further optimize as follows：
High-power laser optical fiber preferably fixed form is fixed for embedding, i.e., be provided with hole for injecting glue on the side wall of tail pipe, high
Bonding agent embedding is adopted between power laser optical fiber and tail pipe center inner wall.Wherein, bonding agent is preferably with unstressed bonding agent.
Certainly, the other modes such as cassette, screw are fixed, capillary tube is fixed can also be grabbed to high power using three in tail pipe
Laser fiber is fixed.
Lock pin outer wall and one end tight fit of corresponding internal surface of sleeve pipe, expose set in one end of described sleeve pipe inwall and lock pin
One nut of socket realizes that the reliability of lock pin itself is fixed jointly for the part of pipe；The outer wall of tail pipe is another with corresponding internal surface of sleeve pipe
End threaded connection.
This utility model has advantages below：
1st, by increasing a tail pipe so that be divided into two sections of isolation, therefore the tightening of optical fiber to the fastening effect of optical fiber
Effect is substantially better than traditional structure.For example, when overall structure is in design than traditional size to 1/3rd (tailpipe of the youthful and the elderly
Position) when, power of the optical fiber in transmission apparatuss dynamic change floats less than 5%, and (optical fiber of conventional size is dynamic in transmission apparatuss
Power when state changes floats more than 10%).
2nd, tail pipe is connected with lock pin by sleeve pipe, and lengthens tightening to connecting portion using nut, is further increased slotting
The reliability of core itself is fixed.
Description of the drawings：
Fig. 1 is the schematic diagram of traditional laser fiber adapter.
Fig. 2 is tail pipe structure schematic diagram of the present utility model.
Fig. 3 is the schematic diagram of high-power laser optical fiber adapter of the present utility model.
Fig. 4 wears the schematic diagram connect after optical fiber for Fig. 3.
Drawing reference numeral explanation：
1-lock pin；2- sleeve pipes；3- tail pipes；301- hole for injecting glue；4- nuts.
Specific embodiment：
As shown in Figure 2, Figure 3 and Figure 4, the present embodiment increases sleeve pipe-tail on the basis of conventional laser fiber adapter
Tubular construction, the i.e. port of export in lock pin are also fixedly connected with a tail pipe by sleeve pipe；The tail pipe through, and with lock pin inside
Axial channel and sleeve pipe it is coaxial, high-power laser optical fiber sequentially passes through lock pin, sleeve pipe and tail pipe.Sleeve pipe respectively with insert
Core, tail pipe preferably connected mode is：One end tight fit of lock pin outer wall and corresponding internal surface of sleeve pipe, in described sleeve pipe inwall
One end and lock pin expose part one nut of common socket of sleeve pipe and realize that the reliability of lock pin itself is fixed；The outer wall of tail pipe with it is corresponding
Internal surface of sleeve pipe the other end threaded connection.
Hole for injecting glue is provided with the side wall of tail pipe, using unstressed viscous between high-power laser optical fiber and tail pipe center inner wall
Agent embedding is connect, with the stability for ensureing to couple.
So, lock pin and tail pipe produce separate fastening effect to optical fiber respectively, therefore the tightening effect of optical fiber is bright
It is aobvious to be better than traditional structure, greatly improve the reliability of optical fiber.Jing is tested, when overall structure is in design than traditional size
During to the youthful and the elderly 1/3rd, power of the optical fiber in transmission apparatuss dynamic change floats less than 5%, and (optical fiber of conventional size exists
Power during transmission apparatuss dynamic change floats more than 10%).
