There are sliding motion between through-hole and compression bar, the two is shaft hole matching, cooperates precision H7/h6, it is ensured that phase between through-hole and compression bar
To the smoothness of movement, the offset of the direction of motion does not occur.Gland 4 pushes compression bar by bulb, and compression bar is by holddown spring to pressure
Arm applies active force, so that pressure arm rotates with 8 for axis, rotation rear pressing arm is in contact with 10, then before this, holddown spring
Length remain unchanged, there is no relative motions for pressure arm and compression bar；After being in contact, gland 4 continues to press on compression bar movement,
Opposite sliding occurs between compression bar and pressure arm at this time, holddown spring is compressed, and by the elastic force of spring, further applies pressure to 10
Power realizes Compliant pressure by the buffering of spring, guarantees that multiple pressure arms can well be contacted with 10, the pressure being applied on 10
Power is almost the same, avoids hardness and compresses the unbalanced problem of bring pressure.
Compression bar consists of the following components: 18 be bulb, and 19 be holddown spring, and 20 be pressure shaft, and 21 be reset spring,
The stiffness factor of middle reset spring 21 be much smaller than holddown spring 19, wherein the set-up mode of bulb can there are many, one is adopt
With fixed bulb, another is that sliding is realized using the bulb of ball-type.
Fig. 2 (a) is the state that pressure arm 3 compresses, and pressure arm 3 is pressed on the positioning head 10 of coupler pin head at this time, is passed through
The pressure of holddown spring, it is ensured that locked between coupler plug and coupler socket；Fig. 2 (b) is the state that pressure arm 3 unclamps, this
When pressure arm 3 and the positioning head 10 on 9 head of coupler plug unclamp, coupler plug 9 may pass through the hole in the center of gland 4, via
This hole is inserted into or leaves.When gland 4 is moved to 3 direction of pressure arm, pressure arm 3 enters impaction state from releasing orientation: resetting bullet
Spring 21 is compressed first, so that pressure arm 3 is rotated along pin shaft, until pressure arm 3 and the positioning head 10 on 9 head of coupler plug connect
Touching；Then holddown spring 19 is further compressed, so that generating biggish pressure between pressure arm 3 and coupler pin head, is made
It obtains and is locked between coupler plug and coupler socket.After locking between coupler plug and coupler socket, spiral shell can be used
Silk, buckle or a kind of any other fixed device lock the position of gland 4, and this mechanical lock mode is in the prior art
In may be implemented there are many means, details are not described herein.
In embodiment one, when axial movement of the gland along connector sleeve is described in detail, to the active force transmitting side of pressure arm
Formula, but the device for realizing that gland moves this process is not had a detailed description.Embodiment two, three, four respectively describes three kinds
The implementation of gland telecontrol equipment.Embodiment five describes a kind of alternative solution of reset spring.

In the present embodiment, the lower end of gland 4 is fixed, and operator in operation, pushes the upper end of gland 4 to implement locking.This
Embodiment has an advantage that the distance of end motion is very short on gland 4, and not needing the very big stroke of rotation can be only achieved the effect of compression
Fruit.The convenience of another aspect is brought for user.In actual use, need to consider the relationship of movement travel Yu spent active force
To consider specific selecting type scheme.
Example IV
It is one of according to the fiber bundle coupling device pressure arm part locking action in the present invention shown in Fig. 5 (a) (b)
The structural schematic diagram of embodiment four, in this embodiment, other structures and the complete phase of structure in embodiment one
Together, translational slide is set between pedestal 1 and gland 4 unlike, and the fixed part and pedestal 1 of slide unit are rigidly connected, slide unit
Motion parts and gland 4 be rigidly connected, the motion parts of slide unit can be by driving device manually or electrically or pneumatically or hydraulically
It pushes, gland 4 is driven to carry out horizontal movement, so that pressure arm 3 be driven to implement locking and release to plug.
In the present embodiment, gland 4 is controlled by a driving device, and gland 4 is driven to be moved.The benefit of this embodiment exists
In such forms of motion is easy to use electric or pneumatic or hydraulic-driven mode to push the movement of gland 4, helps
In realization automatic impaction.In the case where there is automatically lock demand, this embodiment is with the obvious advantage.
Embodiment five
It is one of according to the fiber bundle coupling device pressure arm part locking action in the present invention shown in Fig. 6 (a) (b)
The structural schematic diagram of embodiment five is arranged at the shaft of pressure arm 3 unlike other mechanisms in this embodiment
Torsionspring is, it can be achieved that the function similar with reset spring, and in this case, when gland 4 unclamps, torsionspring 22 is replaced
Reset spring realizes the release to plug so that pressure arm 3 is opened.
In the present embodiment, using torsionspring instead of common reset spring.The volume ratio reset spring of torsionspring
It is small, facilitate the volume for reducing pressure arm part using torsionspring, has certain help to the miniaturization of coupler.
As schemed shown in upper embodiment, wherein component is not strictly defined as the implementation in above-described embodiment, on the contrary, In
In embodiments of the present invention, replacement can be combined, be subject to and reach optimal locking state in the present invention.
In the above-described embodiment,
Material used by positioning head 10 is mainly 6061 metals that aluminium alloy isodensity is small, intensity is high, processing performance is good
Material, the material that matched pressure arm mainly uses is 304 stainless steels or the 6061 higher metal material of aluminium alloy equal strength.
In the above embodiment, from the service life for extending coupler, since plug and the fiber optic bundle of coupler are fixed
It together, is consumables, therefore in design, the material of connector sleeve and the material of pressure arm, hardness are required to rub proofness

The tolerance fit of h6 realizes precision and plugs the balance of flexibility ratio.2. algorithm feeds back to realize --- by being total to what is got
The analysis of focusedimage, can find the center of fiber optic bundle, thus judge fiber optic bundle with couple object lens it is opposite deviate away from
From then by the amendment of algorithm, the residual deviation that correction pass-through mode 1 could not solve again reaches on final image
Alignment.
As it will be easily appreciated by one skilled in the art that the foregoing is merely illustrative of the preferred embodiments of the present invention, not to
The limitation present invention, any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should all include
Within protection scope of the present invention.
