Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail:
Composition graphs 2, the utility model provides the joints of optical fibre of a kind of lasso and V groove main structure body integral type, comprising: collar 7 and the V groove main structure body portion 8 integrally formed with collar 7;
Wherein, collar 7 is built-in with fiber optics fixed orifice 9, and fiber optics fixed orifice 9 extends to the middle part in V groove main structure body portion 8 from the end face of collar 7; V groove main structure body portion 8 is also provided with the fiber optics introduction hole 10 be communicated with fiber optics fixed orifice 9; In practical application, fiber optics fixed orifice 9 is the hole of V groove structure, and for introducing fixed light fiber, its internal diameter can be 0.125 millimeter, and the external diameter of collar 7 can be 2.5mm;
Acting as of above-mentioned V groove structure: be connected and fixed fiber optics and introduce fiber optics, therefore, V groove shape and size affect extremely important on fixed light fiber and the degree of stability introduced when fiber optics is interconnected, in the utility model, inventor is through repeatedly attempting, repeatedly study, when finding to adopt V flute profile formula and internal diameter to be 0.125 millimeter, degree of stability when fixed light fiber can be made to be connected with introducing fiber optics reaches maximal value.
Therefore will use environment material stable especially, the dimensional stability of V groove shape is also extremely important.
In addition, the material in collar 7 and V groove main structure body portion 8, also very large with the impact of the degree of stability introduced when fiber optics is connected for fixed light fiber, in the utility model, collar 7 and V groove main structure body portion 8 adopt the identical material stable especially to environment, concrete, adopt all highly stable pottery of machinery or high temperature, low temperature and plastic material
In addition, do not disturb when the middle part be connected in order to collar 7 and V groove main structure body portion 8 contact with other utensils, in collar 7, and the crossing end face side of close collar 7 and V groove main structure body portion 8, be provided with interference preventing slots 11.
As shown in Fig. 3, Fig. 4 and Fig. 5, the use process chart of the joints of optical fibre of the lasso provided for the utility model and V groove main structure body integral type, comprises three steps:
Step 1, cuts off the fixed light fiber 12 prepared by regular length, wherein, the right side of fixed light fiber 12 is used for being connected with introducing fiber optics, and therefore, the right side of fixed light fiber 12 has the stable section of cross section dissengaged positions 13;
Step 2, by fixed light fiber 12 by from left to right sequentially, inserts from the rear end face of V groove main structure body, and makes the left side of fixed light fiber 12 stretch out certain length from collar left side 14;
Now, in the fiber optics fixed orifice 9 of collar, there is bonding agent, after inserting fixed light fiber 12, through fixing after a while, stablize.Meanwhile, with the right side of introducing the fixed light fiber 12 that fiber optics is connected, only specified length is stretched from collar.
Step 3, cuts off the fixed light fiber 12 stretched out from collar left side 12 and grinds.
Certainly, when grinding, this part don't fail to be wrapped protection, in order to avoid enter impurity in fixed light fiber 12.By the structure of collar and V groove main structure body integrally, stable lead-in wire can also be obtained.
The joints of optical fibre of the lasso that the utility model provides and V groove main structure body integral type have the following advantages:
(1) lasso and V groove main structure body utilize mould to realize integral structure, do not need Assembling, effectively improve the stability of the joints of optical fibre, reduce the optical communication system caused by external environment condition etc. and occur light connection loss, improve optical communication service quality;
(2) mode that fixed light fiber inserts from the rear end face in V groove main structure body portion is fixed by employing, have the advantages that advance preventing is bonded at the impurity such as the bonding agent of lasso and fixed light fiber peripheral, therefore, the outside of the joints of optical fibre there will not be the impurity such as bonding agent completely, can quick, convenient, accurately by joints of optical fibre incoming fiber optic adapter, improve the efficiency of packaging technology, shorten the time of packaging technology.
(3) collar 7 and V groove main structure body portion 8 adopt the stable pottery of temperature variation or precise plastic, made by mould, wherein, collar 7 and V groove main structure body portion 8 adopt identical material, but not in prior art, often adopt unlike material to make, make the product finally made have good stability.
By the above-mentioned field connection-type fiber optic connector provided, effectively can reduce the impact that machinery or environment cause fiber optic cables, the stability after extended fiber cable connects and service time, improve optical communication service quality.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should look protection domain of the present utility model.
