As shown in fig. 1 to fig. 3, an embodiment of the present invention provides a jig for holding an optical fiber against rotation, which includes a base 10, a fiber clamping block 20, and a fiber pressing cover 30, where the fiber pressing cover 30 includes a plate 31 and a connector 32. In the design of the fixture for holding the optical fiber without rotation, the base 10 is provided with a fiber pressing area 11, the fiber pressing area 11 is provided with a fixing portion 111 abutting against the optical fiber 100, the fiber clamping block 20 is slidably disposed in the fiber pressing area 11, two opposite side walls between the fiber clamping block 20 and the fixing portion 111 form a placing space in which the optical fiber 100 can be placed, the connecting body 32 is fixedly connected to one side of the plate 31, the connecting body 32 is rotatably connected to the base 10 through a rotating shaft 50 and located in the fiber pressing area 11, and the connecting body 32 has a force applying edge 321. When the plate 31 is covered toward the fiber pressing area 11, the force application edge 321 pushes the fiber clamping block 20 to make it transversely slide toward the fixing portion 111; when the plate 31 is opened away from the fiber pressing area 11, the force applying edge 321 is separated from the fiber clamping block 20, and at this time, the fiber clamping block 20 is not applied with force by the force applying edge 321, so that the fiber clamping block 20 can reversely slide away from the fixing portion 111, thereby loosening the optical fiber 100.
In the embodiment of the present invention, the base 10, especially the fixing portion 111, is made of epoxy resin material. Moreover, the fiber clamping block 20 is made of a flexible material, such as a rubber material with certain flexibility.
When the fixture for clamping and fixing the optical fiber 100 is used for clamping and fixing the optical fiber 100, the optical fiber is placed in a placing space formed between the fiber clamping block 20 and the fixing part 111, then the optical fiber pressing cover plate 30 is rotated to rotate around the central axis of the rotating shaft 50 until the force application edge 321 pushes the fiber clamping block 20 to transversely slide towards the fixing part 111 to clamp and fix the optical fiber 100, and the force application edge 321 pushes the fiber clamping block 20 to stably apply force to the optical fiber only in the transverse direction, so that the optical fiber is stressed in the transverse direction and is not compressed and generates torque for rotating the optical fiber, and the optical fiber 100 does not rotate under the condition that the optical fiber 100 is clamped and fixed by the stable force application, and the fixture is beneficial to efficiently and smoothly butting, welding, producing and the like the optical fiber with an inclined plane or the optical device with an inclined plane.
As shown in fig. 6, after the optical fiber 100 is processed, the fiber pressing cover 30 is rotated reversely, so that the force applying edge 321 is separated from the fiber clamping block 20 to enable the fiber clamping block 20 to slide and release the optical fiber 100 for easy removal, and in order to remove the optical fiber 100 more conveniently without manually sliding the fiber clamping block 20, the two opposite sides of the fiber clamping block 20 are respectively connected with the elastic arms 21, the fiber pressing area 11 is provided with the installation position-locking portions 112 for correspondingly installing the two elastic arms 21, and after the elastic arms 21 are installed in the installation position-locking portions 112, the elastic arms 21 provide the elastic force for keeping the fiber clamping block 20 away from the fixing portion 111. Thus, when the fiber pressing cover plate 30 is rotated forward so that the force application edge 321 pushes the fiber clamping block 20 to clamp and fasten the optical fiber 100, the elastic arm 21 is compressed to store the elastic force; when the fiber pressing cover plate 30 is rotated reversely to separate the force application edge 321 from the fiber clamping block 20, the elastic force of the elastic arm 21 is released, and the fiber clamping block 20 automatically slides away from the fixing portion 111 under the action of the elastic force, so that the optical fiber 100 can be directly taken down without manually sliding the fiber clamping block 20, which is convenient and fast.
Specifically, in the fiber clamping block 20 of the present embodiment, the two opposite sides of the fiber clamping block 20 are respectively provided with a connecting protrusion 22, a first end of the elastic arm 21 is fixedly connected to an end of the connecting protrusion 22 away from the fiber clamping block 20, a second end of the elastic arm 21 extends toward the fiber clamping block 20, the connecting protrusion 22 serves as a biasing support of the elastic arm 21, and the second end of the elastic arm 21 abuts against a sidewall of the mounting block 112.
Referring to fig. 1 to 3, in order to prevent the fiber pressing cover plate 30 from being opened randomly when an external force is applied to the fiber pressing cover plate during the process of clamping and placing the optical fiber 100, the fixture further includes a cover plate stabilizing structure 40, and when the plate body 31 is covered toward the fiber pressing area 11, the cover plate stabilizing structure 40 can stabilize the plate body 31 on the fixing portion 111. Preferably, the cover plate stabilizing structure 40 is a magnet block, the fixing portion 111 has an installation groove 41, the magnet block is fixedly installed in the installation groove 41, accordingly, the plate body 31 is made of a magnetic material, and preferably, the entire cover plate 30 is made of a metal material with magnetic attraction property. When the fiber pressing cover plate 30 is rotated forward so that the force application edge 321 pushes the fiber clamping block 20 to clamp and fasten the optical fiber 100, the plate 31 covers and presses the optical fiber 100 to a certain extent, and the plate 31 made of magnetic material is magnetically stabilized by the magnet block, so that the optical fiber 100 is not only clamped and fixed by the fiber clamping block 20 and the fixing portion 111 in the horizontal direction, but also compressed by the plate 31 to a certain extent in the vertical direction, and the optical fiber 100 is further stably clamped and fixed without rotating. Even if the plate 31 is not covered at the top contact position of the fixing portion 111 in the covering process (i.e. the cover plate 31 does not press the optical fiber 100 from top to bottom), the magnet block has a certain magnetic attraction force on the plate 31 made of the magnetic material, so that the plate 31 is attracted and stabilized to a certain extent, and the plate 31 cannot rotate reversely freely when receiving an external force within an allowable range, so that the clamping force is not lost. In addition, the cover plate stabilizing structure 40 can also stabilize the plate body 31 by adopting a fastening screw connection mode, namely: offer the bar hole at plate body 31, when plate body 31 rotates to the position that makes application of force limit 321 produce the steady clamping-force, then pass the bar hole on plate body 31 with the holding screw to offer the bar connection groove with the mutual screw-thread fit of holding screw on fixed part 111, thereby screw up the holding screw and stabilize plate body 31.

In the process of rotating the fiber pressing cover plate 30, the force application inclined plane 320 can be always abutted against the corresponding part of the fiber clamping block 20 for pushing until the fiber pressing cover plate rotates to the force application edge 321 to realize stable force application; the force application slope 320 may not contact with the fiber clamping block 20, and after rotating to the force application edge 321, the force application edge 321 directly abuts against the fiber clamping block 20 to realize pushing force application. Or, the connector 32 is provided with an applying arc-shaped surface (not shown), the applying edge 321 is a side edge of the applying arc-shaped surface close to the plate body 31, the applying edge 321 extends parallel to the plate surface of the plate body 31, and the applying arc-shaped surface of the fiber pressing cover plate 30 abuts against a corresponding side surface of the fiber clamping block 20 in the rotating process. When the connector 32 adopts the design of the arc-shaped surface, the arc-shaped surface is a convex arc-shaped convex surface facing the fiber clamping block 20, and the elastic arm 21 is matched to ensure that the arc-shaped surface always abuts against the fiber clamping block 20 to apply force in the process of rotating the fiber pressing cover plate 30 until the fiber pressing cover plate 30 rotates to the force application edge 321 to realize stable force application. In addition, in the embodiment of the present invention, the force application edge 321 may also be a side edge with a curved surface in other forms to apply force to the fiber clamping block 20, which is not limited herein.
