Detailed Description
The present application is described in further detail below with reference to the drawings and specific examples.
Fig. 1 is a schematic diagram of a fiber-optic receiving and coupling device.
The optical fiber receiving and coupling device can comprise a flange 1, a retainer ring 2, a lens 3, an optical fiber assembly 4, a pressing sleeve 5 and a protective tail sleeve 6.
The flange 1 is hollow. The retainer ring 2, the lens 3, and the optical fiber assembly 4 may be accommodated in the cavity of the flange 1. The pressing sleeve 5 and the protective tail sleeve 6 can be arranged on the outer side of the flange 1. The first end of the flange 1 is used for arranging the lens 3. The fiber optic assembly 4 may be inserted into the flange 1 from a second end of the flange 1. Flange 1 may provide a mechanical stop for lens 3 and fiber optic assembly 4.
The flange 1 is provided with a step in the inner wall near the first end, the inner diameter of which step can be matched with the outer diameter of the lens 3. The lens 3 may rest against a step to define the axial position of the lens 3 in the flange 1. The lens 3 may be fixed in the flange 1 by means of the collar 2 and glue. As shown in the enlarged partial view of fig. 1, the step inside the flange 1 is provided with a chamfer to avoid damage to the lens and the optical fiber assembly.
At a first end of the flange 1, a glue injection hole 12 is provided. The glue injection hole is a groove body formed on the side wall of the flange 1 and is axially positioned on one side of the step far away from the optical fiber assembly 4. When the retainer ring 2 is installed in the flange groove of the flange 1 and is abutted against the lens 3, the glue injection ring groove on the outer ring side wall of the retainer ring 2 can be arranged opposite to the glue injection hole. The glue is injected through the glue injection holes, so that the glue 11 can be filled in the glue injection holes and in the glue pits on the retainer ring 2, and the retainer ring 2 is fixed on the flange 1, so that the position of the lens 3 in the flange 1 is fixed. In addition, a gel may be filled between the retainer ring 2 and the lens 3.
The side wall of the flange 1 is also provided with a glue injection hole 13, a glue injection hole 14 and a glue injection hole 15. The glue injection holes 13, 14 and 15 may correspond to the front, middle and tail handles of the optical fiber ferrule 9, respectively. The middle outer diameter of the fiber ferrule 9 may be larger than the front outer diameter of the fiber ferrule 9 and larger than the tail shank outer diameter of the fiber ferrule 9. The adhesive 11 is injected from the adhesive injecting holes 13, 14 and 15, and the axial position of the optical fiber assembly 4 is fixed in a segmented manner.
It should be noted that the amount of glue on the side close to the end face of the optical fiber should not be excessive, so as to avoid polluting the end face of the front-end optical fiber. As shown in fig. 1, there may be a certain gap between the inner wall of the flange 1 and the front portion of the fiber ferrule 9, and a certain adhesive 11 may be stored in the gap. The gap size should be as suitable as possible to provide a margin for assembly of the fiber optic assembly 4, to facilitate distribution of the adhesive 11 around the fiber optic ferrule 9 but not to the fiber end face.
The side of the glue injection hole 14 close to the lens 3 may be projected to the front of the fiber stub 9, and the side of the glue injection hole 14 away from the lens 3 may be projected to the middle of the fiber stub 9. Therefore, the adhesive 11 injected from the adhesive injection hole 14 can be filled between the flange 1 and the end face of the middle part of the optical fiber ferrule 9, so that the adhesive stability of the optical fiber ferrule 9 is improved.
The gap between the flange 1 and the tail handle of the optical fiber ferrule 9 can be relatively large, so that the glue filling amount of a local position can be increased, the bonding stability of the optical fiber ferrule 9 is improved, and the glue is not excessively filled.
In the embodiment of the present application, the material of the adhesive 11 may be a material with a thermal expansion coefficient similar to that of the optical fiber or the lens. The optical fiber receiving and coupling device can use only a single kind of adhesive and does not involve multiple kinds of mixing.
As shown in fig. 2, which is a schematic view of a fiber assembly, the fiber assembly 4 may include a fiber inner sheath 7, a fiber outer sheath 8, a fiber ferrule 9, and an optical fiber 10 therein. The optical fiber 10 penetrates into the optical fiber core 9 and is firmly bonded with the optical fiber inner sheath 7, and the optical fiber outer sheath 8 leaves a certain length allowance, so that the optical fiber core is convenient to press and connect with the flange 1 after being assembled. When the light component 4 is inserted into the flange 1, the pressing sleeve 5 can press the optical fiber outer sheath 8 to the tail of the flange 1. The protective tail sleeve 6 is provided with a groove matched with the pressing sleeve 5 and is used for being matched with the pressing sleeve 5. The crimping part of the optical fiber outer sheath 8 and the flange 1 is protected by a soft protecting tail sleeve 6.
Fig. 3 shows a schematic diagram of an assembly structure of the press sleeve 5, the optical fiber outer sheath 8 and the flange 1. The pressing sleeve 5 is used for pressing the optical fiber outer sheath 8 to the tail part of the flange 1, so that the optical fiber optical coupling device has certain tensile strength. The optical fiber outer sheath 8 may be a woven mesh, and the material of the optical fiber outer sheath 8 itself may have a certain tensile strength. In addition, due to the uneven nature of the outer sheath 8 itself, the resistance to falling off after crimping can be increased, thereby improving the tensile strength of the optical fiber coupling device.
As shown in fig. 4, the pressure sleeve 5 is in pressure connection with the outer sheath 8 of the optical fiberSchematic diagram, taking hexagonal crimping as an example, the force F of the jacket to the outer jacket of the optical fiber is exerted by the jacket L Equivalent to force F exerted on the outer sheath of the optical fiber by six crimping surfaces after crimping T The sum, i.e. F L ＝6μF T Mu is the coefficient of friction, force F exerted by a single crimp face on the outer jacket of the optical fiber T In order to product the shearing strength of the material and the cross-sectional area of a single press-contact surface, the relation between the tensile strength and the material and the size of the press-contact surface of the press-contact sleeve can be established, and the outer diameter D of the press-contact position of the flange tail part, the outer diameter D of the press-contact part and the thickness t of the press-contact part meet the following conditions
And an assembly space is reserved for the optical fiber outer sheath.
The specific assembly steps of the optical fiber receiving and coupling device are as follows:
(1) The flange 1 is arranged vertically upwards on one side for installing the lens, so that the lens 3 and the retainer ring 2 are convenient to install.
(2) The adhesive 11 is coated on the outer side of the lens 3 for one circle and is placed at the step part of the flange.
(3) The adhesive 11 is coated on the outer side of the retainer ring 2 for a circle and is placed in the flange and on the front side of the lens.
(4) Lightly pressing the retainer ring to enable the retainer ring, the lens and the flange to be directly attached without warping, and performing pre-curing.
(5) And injecting an adhesive 11 into the adhesive injection hole 12 at the front end of the flange 1 and the retainer ring adhesive injection ring groove, and curing.
(6) And (3) horizontally placing the glue injection hole 12 of the flange 1 upwards, injecting laser into the lens, coating the adhesive 11 on the periphery of the outer side of the tail handle of the optical fiber insert core 9 of the optical fiber assembly 4, penetrating the flange 1, finely adjusting the axial position of the optical fiber insert core 9 in the inner hole of the flange, and monitoring the optical performance of the assembly on line until the performance is optimal.
(7) The adhesive 11 is injected into the adhesive injecting hole 14 (middle adhesive injecting hole) above the flange 1 at one time, the adhesive 11 is injected into the adhesive injecting hole 13 (left adhesive injecting hole) above the flange at one time after the adhesive 11 is observed to be filled with the adhesive, the adhesive injecting hole is stopped after the adhesive 11 is observed to be filled with the adhesive, the adhesive is not repaired any more, and the pre-curing is carried out.
It should be noted that, since the glue injection hole 13 is close to the end face of the optical fiber, the glue amount should not be too large. When the glue injection hole 13 is observed to overflow the adhesive 11 after the glue injection hole 14 is injected, the glue injection amount of the left side hole should be properly reduced.
(8) The adhesive 11 is injected into the adhesive injection hole 15 (the adhesive injection hole on the right side) above the flange, and the injection is stopped when the adhesive overflow is observed at the tail part of the optical fiber insert core or the adhesive injection hole 14, so that the curing is performed.
While the invention has been described in terms of the preferred embodiment, it is not intended to limit the invention, but it will be apparent to those skilled in the art that variations and modifications can be made without departing from the spirit and scope of the invention, and therefore the scope of the invention is defined in the appended claims.
