The technical solution in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures. Meanwhile, in the description of the present application, the terms "first", "second", and the like are used only for distinguishing the description, and are not to be construed as indicating or implying relative importance.

First embodiment

The embodiment of the present application provides an optical fiber merging device 100. Referring to fig. 1, fig. 1 is a schematic view of an optical fiber merging device 100 according to an embodiment of the present disclosure.

As shown in fig. 1, the fiber combining device 100 may be connected to an air pump 20 through a conduit. The optical fiber merging device 100 may include a base 110 and a merging clamp 120.

The base 110 is used for mounting the fiber combining clamp 120 and is also used for connecting with the air pump 20.

The fiber combining clamp 120 includes a first surface and a second surface. The first surface may be an upper surface of the fiber combining jig 120, and the second surface may be a lower surface of the fiber combining jig 120.

As shown in fig. 2, a wire placing groove 121 for placing an optical fiber is formed on the first surface, and a through hole 122 is formed at the bottom of the wire placing groove 121. The second surface is provided with a suction groove 123. One or more optical fibers can be placed in the same slot 121. Wherein "X" in fig. 2 denotes an optical fiber.

When the fiber combining clamp 120 is mounted on the base 110, a cavity (not shown) is formed between the suction groove 123 and the base 110. Under the air pumping action of the air pump 20, negative pressure is generated in the wire placing groove 121, so that the optical fiber in the wire placing groove 121 can be adsorbed at the bottom of the wire placing groove 121.

Through the optical fiber combining device 100, a cavity can be formed between the suction groove 123 and the base 110 in a matching manner, and the cavity can be matched with the through hole 122 on the wire placing groove 121 to form a communication area, so that the suction force is increased. Under the suction action of the air pump 20, a larger negative pressure can be generated in the wire-arranging groove 121 through the conduit and the communicating area. If optical fibers are arranged in the fiber arrangement groove 121, the optical fibers in the fiber arrangement groove 121 can be adsorbed at the bottom of the fiber arrangement groove 121, each optical fiber does not need to be fixed in a manual mode, rapid fixing of the optical fibers is achieved, and damage to the optical fibers in a manual fiber combining process can be avoided. In addition, because the shape of the wire arrangement groove 121 is fixed, and the position of the through hole 122 in the wire arrangement groove 121 is fixed, the relative position of the optical fiber placed in the wire arrangement groove 121 can be determined, the number of times of position debugging on the optical fiber in the fiber combining process is reduced, the optical fiber can be quickly adsorbed in the wire arrangement groove 121, and quick fiber combining is realized.

Optionally, the wire-placing groove 121 may be a rectangular groove, a "V" groove, or a "U" groove, as long as a position where the through hole 122 can be opened is left at the bottom of the wire-placing groove 121.

In one example, the fiber placement groove 121 is a "V" groove, and placing the optical fiber in the "V" groove is advantageous for enhancing the fixation of the optical fiber.

The size and tolerance of the wire arrangement groove 121 provided by the embodiment of the application can be set according to requirements. During specific use, the fiber combining number and the fiber combining tolerance in the wire placing groove 121 can be controlled based on the size and the tolerance set by the wire placing groove 121, so that rapid and accurate fiber combining can be performed, a plurality of optical fibers can be combined together, and the accuracy and the operability of subsequent processing procedures can be improved. Wherein, the subsequent processing procedure can be a dispensing procedure.

Optionally, an air passage (not shown) is disposed in the base 110, one end of the air passage is used for connecting a conduit of the air pump 20, and the other end of the air passage is used for communicating with the cavity.

The air passage can provide an air flow transmission path between the air pump 20 and the cavity, and the air passage can be matched with the cavity and the through hole 122 to enhance the adsorption force.

In one example, when the air pump 20 is turned on, the air channel can generate the negative pressure required for fixing the optical fibers in the V-shaped groove, the negative pressure for fixing one optical fiber can be-0.2 MPa, and the negative pressure for fixing two optical fibers can be-0.4 MPa. The specific negative pressure value can be set according to actual needs and the number of fibers.

Alternatively, as shown in fig. 4, the through hole 122 is a strip-shaped through hole 122, and the extending direction of the through hole 122 is the same as the extending direction of the wire placing groove 121.

Because the through hole 122 is strip-shaped, and the extending direction of the through hole 122 is the same as the extending direction of the wire placing groove 121, compared with the structure of the circular through hole 122 or the square through hole 122, the matching area between the strip-shaped through hole 122 and the linear optical fiber is larger, larger negative pressure can be generated in the wire placing groove 121, and the optical fiber in the wire placing groove 121 has larger adsorption force. And the tool operation mode of the strip-shaped through hole 122 is simple, and the punching operation on the same extension line is not required for multiple times.

In addition, compared with a mode that a plurality of through holes 122 are arranged in the same wire arrangement groove 121 to absorb the same optical fiber, even if the number of the strip-shaped through holes 122 is small, the optical fiber can be absorbed with strong polarity, and in one example, the optical fiber can be absorbed and fixed by one strip-shaped through hole 122.

Optionally, the number of the strip-shaped through holes 122 in the same wire placing groove 121 may be one or multiple.

If a strip-shaped through hole 122 is adopted, the fixation of a single optical fiber can be realized, and thus the single-core optical fiber is obtained. If a plurality of strip-shaped through holes 122 are arranged in the same wire arrangement groove 121, a plurality of optical fibers in the same wire arrangement groove 121 can be fixed, and subsequent processing is facilitated to form the multi-core optical fiber.

In one embodiment, the extending direction of the suction groove 123 may form a predetermined angle with the extending direction of the thread placing groove 121, for example, may form 90 ° or 0 °.

If the extending direction of the suction groove 123 is set to be perpendicular to the extending direction of the wire placing groove 121, it is advantageous to suck the plurality of optical fibers in the plurality of wire placing grooves 121 by the same suction groove 123.

Optionally, the length of the through-hole 122 is less than or equal to the width of the suction groove 123.

In one example, as shown in fig. 3, the length of the through-hole 122 is equal to the width of the suction groove 123.

If the suction groove 123 and the through hole 122 form a specified included angle in the extending direction, the length of the through hole 122 may be less than or equal to the width of the suction groove 123. Because the length of through-hole 122 matches with the width of suction groove 123, can determine comparatively suitable communicating region between through-hole 122 and suction groove 123, can increase the adsorption affinity of the optic fibre in opposite wire casing 121 through communicating region.

For the length of the through hole 122, a person skilled in the art can determine the size of the combined optical fiber according to actual needs, as long as each optical fiber placed in the wire placing groove 121 can cover the through hole 122, so that the phenomenon of air leakage due to the overlarge width of the through hole 122 can be avoided, and the absorption force is reduced.

As an embodiment, the depth of the wire-placing groove 121 may be greater than the diameter of the optical fiber, so that the optical fiber can be completely absorbed in the wire-placing groove 121, and the optical fiber is absorbed and fixed according to the shape of the wire-placing groove 121.

As another embodiment, the depth of the cabling slot 121 may be less than or equal to the diameter of the optical fiber. In this embodiment, the optical fiber may be absorbed in the slot 121, or the upper surface of a portion of the optical fiber may be slightly higher than the first plane P.

Optionally, in order to avoid the optical fiber microbending or weak fixing in the case that the depth of the optical fiber placing groove 121 is less than or equal to the diameter of the optical fiber, the optical fiber combining device 100 may further include a pressure body (not shown).

The bottom surface of the pressure body is a plane, and the pressure body can be used for moving towards the wire placing groove 121 so as to apply pressure to the optical fiber in the wire placing groove 121.

Through setting up the pressure body can put the optical fiber in the wire casing 121 evenly to exert pressure under the shallow condition of the degree of depth of wire casing 121, realize the supplementary fixed to optical fiber, promote and fine fixed effect.

It should be noted that the pressure body can control the movement path and the movement speed through the driving assembly. The skilled person can set the moving path and moving speed of the pressure body through practical situations to avoid the optical fiber in the cabling slot 121 from being damaged due to excessive pressure.

As an implementation manner, the pressure body may be pivotally connected to the first surface, and when the pressure body is required to apply pressure to the optical fiber, the pressure body may rotate to above the wire-placing groove 121, and then move toward the optical fiber in the wire-placing groove 121, so as to uniformly apply pressure to the optical fiber in the wire-placing groove 121.

As another implementation, the pressure body may be erected above the wire-placing groove 121. For example, the pressure body may be mounted on a support frame, which may be disposed on the base 110 or above the fiber combiner 100. The elastic piece on the supporting frame can drive the pressure body to move towards the wire placing groove 121 so as to apply pressure to the optical fiber in the wire placing groove 121.

Wherein in other embodiments the pressure body may be omitted.

Optionally, the first surface is provided with a plurality of wire placing grooves 121 arranged side by side.

Through a plurality of wire casing 121 of putting that set up side by side, can once only carry out and fine fixed to many optic fibres, improved and fine efficiency.

Alternatively, as shown in fig. 3, the first surface may be a stepped surface. The first surface may include a first plane P, a second plane Q. The height of the first plane P is higher than the height of the second plane Q.

As an embodiment, as shown in fig. 5, the first plane P may be used to open a wire-placing groove 121 for placing an un-stripped portion of an optical fiber, the second plane Q may be used to suspend a stripped portion of an optical fiber and may also be used to suspend a portion of the un-stripped portion of the optical fiber, and the second plane Q may be used as a processing platform for performing subsequent processing on the optical fiber.

For example, if the fiber stripping point of the optical fiber is placed on the second plane Q, the subsequent dispensing processing of the optical fiber position on the second plane Q is facilitated.

In other embodiments, the first plane P may be used as a processing platform.

Through establishing the first surface as the step face, and the height of first plane P is higher than the height of second plane Q, because there is the difference in height between first plane P and the second plane Q, can be so that partly suspension of optic fibre is favorable to handling the optic fibre that needs follow-up processing, promotes follow-up processing's maneuverability.

In one example, the slot 121 is a V-shaped slot, the depth of the V-shaped slot is 0.2mm, the width of the V-shaped slot is 0.51mm, the length of the V-shaped slot matches with the second plane Q of the fiber combining clamp 120, two strip-shaped through holes 122 are formed in the slot 121, and the slot 121 can be used for placing optical fibers with the diameter of 250 μm. The width of each through-hole 122 may be 0.2mm, the length of the through-hole 122 matches the width of the suction groove 123, and the width of the suction groove 123 may be 11.5 mm.

In other examples, the sizes of the wire arrangement groove 121, the through hole 122 and the suction groove 123 can be changed according to actual needs.

When the optical fiber combining device 100 is used specifically, the air pump 20, the conduit and the base 110 may be connected, the fiber combining clamp 120 may be mounted on the base 110, and the sizes of the cabling groove 121 and the through hole 122 may be designed according to the number of the combined fibers and the allowable tolerance. The optical fiber to be combined can be placed in the wire-placing groove 121, and the stripped part and part of the unreleased part of the optical fiber can be placed on a plane outside the wire-placing groove 121 for subsequent processing. Air is pumped by the air pump 20, negative pressure is generated in the wire placing groove 121, so that the optical fiber in the wire placing groove 121 generates adsorption force, the optical fiber is attached to the bottom of the wire placing groove 121 under the action of the adsorption force, and the optical fiber is fixed. Through the operation steps, a plurality of optical fibers can be fixed in the plurality of wire arrangement grooves 121, and fiber combination of a plurality of groups of optical fibers can be realized. Fig. 6 shows a schematic view of a slot 121 in which two optical fibers ("X" for optical fibers) are placed, which can be used to process a dual-core optical fiber.
