Embodiment
Below, with reference to accompanying drawing, the preferred implementation of optical connector involved in the present invention is elaborated.
Fig. 1 means the general profile chart of an embodiment of optical connector.In the figure, the optical connector 1 of present embodiment is the optical connector of mechanical splice (Mechanical splice) type.
Optical connector 1 has: with the mechanical splice section 2 of lock pin, it is with mechanical connection between optical fiber and fixing; And housing (not shown), it covers this section of mechanical splice with lock pin 2.
, have as shown in Fig. 1 and Fig. 2 (a) with the mechanical splice section 2 of lock pin: base portion 5, it has the optical fiber duct 4 for the section V word shape of location and up-winding fiber 3; Cap 6, its optical fiber 3 that will be housed in optical fiber duct 4 is pressed to base portion 5; And the fastening spring 7 of section U word shape, its clamping base portion 5 and cap 6.Base portion 5 and cap 6 form resinous optical connection member 8., for the fore-end of optical fiber 3, remove clad and expose naked fine 3a.Naked fine 3a is formed by quartz glass.
Leading section in base portion 5 is fixed with lock pin 9.Lock pin 9 is keeping the built-in fiber 10 of short strip shape.Built-in fiber 10 has identical structure with above-mentioned naked fine 3a, extends to the optical fiber duct 4 of optical connection member 8 from the front end face (connecting end surface) of lock pin 9.
Be provided with on base portion 5 in optical connection member 8 and the boundary member of cap 6 for a plurality of wedges that wedge parts 11 are inserted and insert recess 12.Optical connection member 8 is inserted the opposition side clamping of recess 12 from wedge by fastening spring 7.
In above-mentioned optical connector 1, when the built-in fiber 10 in remaining on lock pin 9 is connected with optical fiber 3, as shown in Fig. 2 (b), wedge parts 11 are inserted in the wedge insertion recess 12 of optical connection member 8.So base portion 5 and cap 6 overcome the pretightning force of fastening spring 7 and become the state of opening.
And, as shown in Figure 1, optical fiber 3 is directed in optical connection member 8 from the rear side of the mechanical splice section 2 with lock pin, the front end face of optical fiber 3 is contacted with built-in fiber 10.Be filled with adjustable refractive index agent S in the inside of optical connection member 8, this adjustable refractive index agent S is used for eliminating the optics uncontinuity between optical fiber 3 and built-in fiber 10.
Under above-mentioned state, as shown in Fig. 2 (c), wedge parts 11 are inserted recess 12 and extract from wedge.So base portion 5 and cap 6 be closure due to the pretightning force of fastening spring 7, to be connected with built-in fiber at optical fiber 3 under the state that optics connects via adjustable refractive index agent S, both press fixing by base portion 5 and cap 6.
Base portion 5 and cap 6(optical connection member 8) formed by the amorphous resin that is added with bat wool.Preferably use the engineering plastic resins such as the higher polyetherimide of thermotolerance (PEI) or polyethersulfone (PES) as amorphous resin.
Use Mohs value as bat wool than the little material of quartz glass that forms optical fiber 3, preferably use Mohs value less than 5 material.Mohs value means the index of the hardness of material, between mineral the friction and the damage a side be the less material of hardness.
, as the typical example of above-mentioned bat wool, can enumerate potassium titanate crystal whisker (KTW).In addition,, as bat wool, except KTW, can also use the needle-like fillers such as wollastonite, aluminium borate, alkali magnesium sulfate (MOS), xonolite, zinc paste, perhaps, in order to give other characteristics, also can add the less tabular or spherical filler of Mohs value.
, at this, utilize the PEI whisker resin that adds potassium titanate crystal whisker and obtain in polyetherimide and the fine link of moulding bright dipping, the actual evaluation of carrying out various characteristics.Below, this evaluation result is narrated.
At first, the fracture strength of optical fiber is estimated.Specifically, the optical fiber of having removed the clad of center section is placed in the optical fiber duct of optical connection member, under the state that utilizes cap that optical fiber is pressed to base portion, by fastening spring, applies certain load (approximately 5N).Then, optical fiber is pulled down from optical connection member, optical fiber is placed in the optical fiber cupping machine, the load when optical fiber is applied tensile force and measured fibercuts (fibercuts intensity).
At this moment, the resin material as forming optical connection member, used following 3 kinds of resins: above-mentioned PEI whisker resin; The PEIGF resin that adds glass fibre (GF) and obtain in polyetherimide; And the PEI-N(that does not add filler in polyetherimide is natural) resin.The Weibull figure of the fibercuts intensity of this moment shown in Figure 3.
About 50% fracture strength of optical fiber, be 20 to 30N in PEI whisker resin, be about 5N in the PEIGF resin, be about 30N in the PEI-N resin.With PEI whisker resin and PEI-N resin-phase ratio, fracture strength is less in the PEIGF resin, can expect that thus glass fibre can be to the surperficial injury of optical fiber.In PEI whisker resin and PEI-N resin Fracture intensity about equally, the potassium titanate crystal whisker that Mohs value that hence one can see that is lower hardly can be to the optical fiber injury.
Therefore, as can be known clear and definite, preferably the bat wool that Mohs value is less than quartz glass be added into amorphous resin and the material that obtains as the resin material that forms optical connection member.
At this moment, bat wool is preferably 25 to 35wt% with respect to the filling rate (proportional quantity) of amorphous resin.In above-mentioned PEI whisker resin, the proportional quantity of potassium titanate crystal whisker is made as 30wt%.Be preferably 25 to 35wt% reason as the proportional quantity of bat wool as follows.
Fig. 4 (a) shows the mutual relationship of bat wool with respect to the linear expansion coefficient of the filling rate of amorphous resin and PEI products formed (optical connection member).In mechanical splice section, resin flows and orientation along the length direction of optical fiber duct usually when moulding.Therefore, Fig. 4 (a) illustrates the linear expansion coefficient of the resin flows direction (MD) of PEI products formed.From Fig. 4 (a) as can be known, if the filling rate of bat wool is more than or equal to 25%, there is saturated trend in linear expansion coefficient, and therefore from the viewpoint of linear expansion coefficient, bat wool is preferably more than or equals 25% with respect to the filling rate of amorphous resin.The linear expansion coefficient of optical connection member is for example 1 * 10
-5～3 * 10
-5/ K.
In addition, has impulse test as a kind of in connector standards test.For example under the state in mechanical splice section is housed in housing, optical connector is fallen from certain altitude, to having or not abnormal appearance and optical characteristics (loss variation amount) to estimate this moment.A kind of as in the target of physical strength, exist pulling strengrth or bending strength etc.
Fig. 4 (b) shows the mutual relationship of bat wool with respect to the bend fracture deflection of the filling rate of amorphous resin and PEI products formed (optical connection member).From Fig. 4 (b) as can be known, the addition of bat wool is more, bend fracture deflection less (toughness drop), and therefore, resistance to impact reduces.When having carried out the connector drop test, the filling rate of bat wool greater than 35% sample in, 1/10th mechanical splice section occurs damaged in part.Therefore, from the viewpoint of physical strength, bat wool is preferably and is less than or equal to 35% with respect to the filling rate of amorphous resin.The bend fracture deflection of optical connection member is for example 1 to 4%.
Fig. 5 (a) shows the mutual relationship of bat wool with respect to the surfaceness Rz of the filling rate of amorphous resin and PEI products formed (optical connection member).From Fig. 5 (a) as can be known, the addition of bat wool is more, surfaceness larger (coarse).Fig. 5 (b) shows the mutual relationship of bat wool with respect to the optical fiber withdrawal force of the filling rate of amorphous resin and PEI products formed (optical connection member).From Fig. 5 (b) as can be known, the addition of bat wool is more, and optical fiber withdrawal force (optical fiber confining force) is higher.Therefore, can say that the surfaceness of optical connection member is more coarse, the optical fiber withdrawal force is higher.The surfaceness Rz of the part that contacts with glass optical fiber of optical connection member is for example 1 to 8 μ m.
As shown in present embodiment, the resin material that obtains in the situation that use the bat wool that Mohs value is less than quartz glass to be added into amorphous resin, even the surfaceness of optical connection member is larger, the contact frequency of optical fiber and bat wool is higher, also can the intensity of optical fiber be impacted hardly, therefore, the degree of freedom of the addition of bat wool improves.Therefore, can be to a large amount of fiberfill fibers shape fillers in amorphous resin.
In above-mentioned evaluating characteristics, be made as by potassium titanate crystal whisker and form bat wool, but, for example in order to suppress synthetic resin generation warpage, can use the potpourri of potassium titanate crystal whisker and wollastonite as bat wool.
In addition, in mechanical splice section, filler is more with respect to the loading of resin, dimensional accuracy as the optical connection member (base portion and cap) of synthetic resin is higher, change in size during temperature variation is less, therefore, and the optical characteristics stabilizations such as junction loss.On the other hand,, if the loading of filler is many, occur on the surface of synthetic resin that the ratio of filler uprises., at this, in the situation that as filler, use glass fibre,, due to the Mohs value of glass fibre and quartz glass (7 left and right) about equally, therefore following unfavorable condition can occur.
Therefore that is, due to optical fiber, pressed fixingly by mechanical splice section, sometimes be present in the lip-deep filler of optical connection member to naked fine injury.In the optical connector of particularly installing at the scene, on environment for use, sometimes to optical fiber effect tensile force.Therefore, can expect lip-deep small damage take optical fiber as cause, the strength deterioration of optical fiber, optical fiber can break in the worst case.
On the other hand, in the present embodiment, with optical connection member 8, be that base portion 5 and cap 6 are formed by the amorphous resin that is added with the Mohs value bat wool less than quartz glass, therefore, bat wool is compared abundant softness with the naked fine 3a of optical fiber 3.Therefore, while in the mechanical splice section 2 by with lock pin, pressing fixed fiber 3, the lip-deep optical fiber that is present in optical connection member 8 is difficult to naked fine 3a is caused damage.Therefore,, even to optical fiber 3 effect tensile forces, also can guarantee the physical strength of optical fiber 3.Thus,, even increase the loading of bat wool, also can guarantee with the required characteristic of the mechanical splice section 2 of lock pin (optical characteristics, physical strength, optical fiber confining force) and improve the strength reliability of optical fiber 3.
The present invention is not limited to above-mentioned embodiment.For example the optical connector 1 of above-mentioned embodiment is the optical connector of mechanical splice type that optical fiber 3 is connected with built-in fiber 10, but the present invention also can be applicable to 2 optical fiber are directed into from both sides in mechanical splice section and connect, fixing type.
In addition, the present invention except the mechanical splice section that mechanical connection between optical fiber is also fixed, also can be applicable to the optical connectors such as MT connector ferrule or optical alignment parts.
