Abstract
The utility model relates to an optic fibre device technical field is an open step optic fibre capillary subassembly particularly, the subassembly be the cuboid structure, the inside haplopore passageway, its characterized in that of being equipped with of subassembly: cuboid subassembly structure one side is equipped with a breach, constitutes open step structure, haplopore passageway export one end is located second level stair structure's vertical plane, compared with prior art, the utility model, its advantage lies in: the design of the stepped structure can facilitate the insertion and fixation of the optical fiber, and the open stepped structure can ensure that the stress difference is freely released after the glue is subjected to temperature change, thereby improving the performance and reliability of the product.
Description
Technical Field
The utility model relates to an optic fibre device technical field is an open step optic fibre capillary subassembly particularly.
Background
The fiber tube end portion among the prior art adopts V type or U type taper hole design, and this produces winding phenomenon when leading to optic fibre to insert, and the optic fibre of being not convenient for inserts and fixes, and traditional design structure taper hole is glued the solidification back in the point simultaneously, because the closure of structure for the poor unable complete release of stress that brings of the different expend with heat and contract with cold coefficient between glue and the glass, there is the reliability hidden danger. China discloses a patent: a step flare type optical fiber capillary, patent No.: 2015210285958, the patent is provided with a bell mouth inside, the bell mouth is connected with a step, the patent belongs to an internal step type, compared with the prior art, the patent can solve the problems that the optical fiber is wound when being inserted, and is difficult to fix, etc. But because the patent is an internal step, the structure is still closed, the stress difference between glue and glass cannot be released, and the potential reliability hazard still exists.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to solve the not enough of prior art, provide a simple structure, reasonable in design, reliability and stability are high, simultaneously can save material's optic fibre capillary subassembly.
In order to realize above-mentioned purpose, design an open step type optic fibre capillary subassembly, the subassembly be the cuboid structure, the subassembly is inside to be equipped with haplopore passageway 4, its characterized in that: one side of the cuboid component structure is provided with a notch 3 to form an open step structure, and one end of the outlet of the single-hole channel 4 is positioned on the vertical surface of the second-stage step structure.
The open step type optical fiber capillary component is characterized in that: the single-hole channel 4 is used for penetrating the optical fiber 5, the outlet end of the single-hole channel 4 is connected with the optical fiber 5 and the capillary component by hard glue 1, and soft glue 2 for protection is arranged on the outer side of the joint of the hard glue 1.
Compared with the prior art, the utility model, its advantage lies in:
1. the design of the stepped structure can facilitate the insertion and fixation of the optical fiber.
2. The open step structure can ensure that the glue has poor free release stress after being subjected to temperature change, thereby improving the performance and reliability of the product.
3. The step of one side breach design can save the quantity of glue.

in the figure: 1. hard glue 2, soft glue for protection 3, notch 4, single-hole channel 5 and optical fiber.
Detailed Description
The technical scheme is further explained by combining the attached drawings.
The first embodiment is as follows: see fig. 1 and 2
The subassembly is the cuboid structure, and the inside haplopore passageway 4 that is equipped with of subassembly, cuboid assembly structure one side are equipped with a breach 3, constitute open step type structure, and haplopore passageway 4 export one end is located second level step structure's the face of erectting, and haplopore passageway 4 is used for passing optic fibre 5, and haplopore passageway 4 exit end adopts 1 joint of ebonite to connect optic fibre 5 and capillary subassembly, and the 1 junction outside of ebonite is equipped with flexible glue 2 for the protection.
Example two: see FIG. 1
The capillary tube body is of a cylindrical structure, the diameter of the tube body is 1.5-2mm, the length of the tube body is 4-10mm, and the tube body is made of borosilicate glass. The diameter of the single-hole channel 4 is 0.25-0.5mm, the diameter of the optical fiber 5 passing through the single-hole channel 4 is 0.25mm, and the length of the step-shaped notch 3 is 0.7-1.5 mm.
The product is one of core components of an optical transceiver module, the performance stability of the product is greatly improved along with the increasing of the transmission rate, particularly in the aspect of temperature performance, in a common high-low temperature test with the temperature range of-40-85 ℃, the temperature change rate is generally required to be 2 ℃/min, and the product can meet the temperature rise change rate of 10 ℃/min.
