Description
[technical field]
The present invention relates to connect the quartzy interface unit that optical fiber is used, particularly relate to a kind of double step structure of the V-shaped groove joints of optical fibre that improve product quality and production efficiency.
[background technology]
At present, more and more higher to the requirement of the communication technology along with social development and technical progress, wherein, the advantage such as optical fiber communication is large with its transmission capacity, good confidentiality and obtain high speed development, and become current topmost wire communication mode.The connector of using with the optical-fibre communications equipment connection need be installed in the two ends of used optical fiber in the optical-fibre communications field, and this class connector is made by quartz substrate, and mainly is formed by connecting by V-type groove substrate, cover plate and fibre ribbon.The used V-type groove substrate of traditional joints of optical fibre is the separate unit stage structure.As shown in Figure 1, this kind structure so that optical fiber with after V-type groove substrate is connected, between naked fibre and the step because existing the gap to fit fully, so that naked fibre can break fibre when being subject to external force and cause the probability of product rejection higher.The V-type groove substrate of separate unit stage structure is in assembling process simultaneously, and the size of optical fibre packages coating part on its step estimated control by the staff, causes the degree of accuracy of product and consistance poor, inefficiency.
[summary of the invention]
The present invention is intended to address the above problem, and a kind of disconnected fine rate of product that can effectively reduce is provided, and is easy to realize the standardization of products, effectively guarantees the double step structure of product quality and the V-shaped groove joints of optical fibre of enhancing productivity.
For achieving the above object, the invention provides a kind of double step structure of the V-shaped groove joints of optical fibre, this structure comprises substrate and is connected in the cover plate on substrate top, be provided with the V-shaped groove that a plurality of connection optical fiber are used at the substrate uper side surface, and be provided with recessed first step, it is characterized in that, between described first step and the end away from V-shaped groove, be provided with recessed second step on the substrate.
First step is to be formed by upper surface of base plate turnover downwards, substrate is transferred rear downwards and upper surface of base plate extends to form forward the first plane abreast, described second step is to be formed by the turnover downwards of described the first plane, and the first plane is transferred rear downwards and upper surface of base plate extends to form forward the second plane abreast.
Described optical fiber is naked fibre and is coated on the fibre ribbon that naked fine outside clad consists of that the coupling part of fibre ribbon is the naked fibre of having peeled off clad.
The height of second step is identical with the thickness of the clad of fibre ribbon.
The strip length of the coupling part clad of fibre ribbon is 10～20mm.
When optical fiber was connected with substrate, fibre ribbon placed second plane at described second step place, and naked fibre then extends to the front end of described V-shaped groove through first plane at described first step place, naked fibre and described the first plane and the bonding encapsulation of V-shaped groove.
Contribution of the present invention is that it efficiently solves the disconnected fine problem of the joints of optical fibre when being connected with optical fiber.The present invention is owing to be provided with the second plane at joints of optical fibre substrate, thereby eliminated because of fibre ribbon and naked fibre and placed naked fibre that same plane causes and the gap between the step plane, so that fit closely in naked fibre and plane, therefore can effectively reduce the disconnected fine rate of product, and effectively guarantee product quality.Also owing to the fibre ribbon with unstripped clad places the second step place, therefore need not artificially estimate control, thereby be easy to realize the standardization of products, and can greatly enhance productivity.The present invention also has characteristics simple in structure, easy to implement.

[embodiment]
The following example is to further explanation of the present invention and replenishes, the present invention is not constituted any limitation.
The following example is to further explanation of the present invention and explanation, and the present invention is not constituted any limitation.
Consult Fig. 2, shown in Figure 3, the double step structure of the V-shaped groove joints of optical fibre of the present invention comprises substrate 10, cover plate 20 and fibre ribbon 30.
Optical fiber of the present invention is naked fine 31 fibre ribbons 30 that outside clad 32 consists of with being coated on naked fibre, wherein, clad 32 is epoxy resin or silica gel, the coupling part of fibre ribbon is the naked fibre of having peeled off clad, fibre ribbon 30 must be peelled off the part clad of link and exposes naked fibre when being connected with the V-shaped groove joints of optical fibre, and the strip length of the coupling part clad of fibre ribbon is 10～20mm, in the present embodiment, strip length is 15mm.
Such as Fig. 2, shown in Figure 3, described substrate 10 is rectangular plate shape bodies of being made by tabular quartzy base-material, is provided with the V-shaped groove 11 that a plurality of connection optical fiber are used at substrate 10 uper side surfaces, and middle side part is provided with recessed first step 12 on the substrate 10.This V-shaped groove 11 is arranged along the Width of substrate 10, and extends to first step 12 places by the front end of substrate 10.Described fibre ribbon 30 is connected rear by cover plate 20 cappings with substrate 10.Described cover plate 20 is rectangular plate shape bodies of being made by tabular quartzy base-material, and its shape is corresponding with substrate 10, and its front end by substrate 10 extends to first step 12 places.Cover plate 20 is in a side that is provided with V-shaped groove 11 and 10 involutory connections of substrate of substrate 10, and is adhesively fixed by bonding agent.Main points of the present invention are, such as Fig. 2, shown in Figure 3, are being provided with recessed second step 13 on the substrate 10 between described first step 12 and the end away from V-shaped groove 11.Described first step 12 is to be formed by the turnover downwards of substrate 10 upper surfaces, and in the present embodiment, the turnover face of substrate 10 is the inclined-plane, the step of formed first step 12 for tilting.Extend to form the first plane 121 before the turnover downwards of described substrate 10 upper surfaces is backward, this first plane 121 is parallel with the upper surface of substrate 10.Described second step 13 is to be formed by described the first plane 121 turnover downwards, the height of second step 13 is identical with the thickness of the clad of fibre ribbon 32, so that fibre ribbon is when being connected with the V-shaped groove joints of optical fibre, naked fine 31 of fibre ribbon can be adjacent to the first plane 121, to eliminate the gap between naked fibre and the step.Described the first plane 121 flatly extends to form forward the second plane 131 after the turnover downwards, and this second plane 131 parallels with the first plane 121.By this, formed two scalariform planes that are parallel to each other by first step 12 and second step 13 on substrate 10, wherein, the second plane 131 is used for placing 121 on fibre ribbon 30, the first planes with clad and is used for placing and has peeled off naked fine 31 of clad.As shown in Figure 4, when optical fiber is connected with substrate 10, fibre ribbon 30 front ends are placed second plane 131 at described second step 13 places, naked fine 31 the first planes 121 through described first step 12 places extend to the front end of described V-shaped groove 11, because the thickness of the clad 32 of fibre ribbon is highly identical with second step 13, so that place naked fine 31 on the first plane 121 to be adjacent on the first plane 121, thereby can not occur disconnected fine because of external force.Naked fine 31 with described the first plane 121 and the bonding encapsulation of V-shaped groove 11 usefulness bonding agents.
