Abstract

PURPOSE:To obtain an optical connector of simple constitution which deflects an optical path at right angles with high precision and has superior productivity by providing a recessed surface body which deflects the optical path at right angles to the orthogonal intersection part of a couple of optical transmission lines which are connected to the connector body while crossing each other at right angles. CONSTITUTION:Connector couplers 2 are inserted fixedly into orthogonal intersecting through holes of the connector body 6, and the recessed surface body 3 is fixed to the orthogonal intersecting part of the through holes. Light transmitted through one optical fiber of an optical fiber connector 52 fixed with a cap nut 51 is deflected at right angles by being reflected by the recessed surface A of the recessed surface body 3 to enter the other optical fiber, wherein the light is transmitted. Consequently, the optical connector of simple constitution which deflects the optical path at right angles with high precision and has superior productivity is obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION (1) Technical Field of the Invention The present invention relates to a connector for an original fiber transmission line, and particularly to an original coil and a lid that deflect an optical path at right angles.

(In the optical communication field where the target fiber of the 21st invention is used as an optical transmission line, it is necessary to cut and release the original fiber in 11 ways.)
It is a J decision. Regarding these parts, each 4 ri former carp and
There have been remarkable developments in lids in recent years, most of which are K.
I am a former Koi futa who works on M.

On the other hand, even in the Mottsu 4Fg device, high-density packaging is required due to the miniaturization of various components and elements, and the optical transmission lines used there also have to be arranged in a small space. In such a case, when connecting the original fiber to the circuit device using the conventional original connector mentioned above, there is a limit to the miniaturization of the device because a bending allowance for the original fiber connector and the original fiber that protrude perpendicularly to each other is required in the space. .

In view of these points, the present invention provides an original coaxial connector that can deflect the line at right angles in the original fiber transmission line and minimize the required space, as in the case of electric, lid, and coaxial line connectors. It is an object.

At present, there has been almost no disclosure of known concrete structures of such ex-carp and kuku, and the present invention is intended to show its concrete feasibility.

(31) In terms of the configuration of the invention, it is the configuration summary of the present invention that the pair of optical transmission lines to be connected are orthogonal to the original axis of the respective optical transmission lines, and the pair of optical transmission lines are orthogonal to each other. This is achieved by an original connector consisting of a connector main body formed with a right-angled surface for providing an optical path deflection means to connect the optical paths of the body transport paths, and a concave body of °C as the optical path deflection means provided on the right angle surface. , it is possible to provide an original connector with a simple structure, high 11 degrees, and excellent manufacturability. This will be explained in detail using an example.

FIG. 1 shows an embodiment of the connector of the present invention, shown in side section in a separated state, and FIG. 4 shows the same in an assembled state.

In FIG. 1, the connector main body l is a cubic metal block as shown in the perspective view of FIG. 2, as viewed from the side. Through-holes 11 and 12 are bored in each surface to have the same inner diameter so that their axes are perpendicular to each other at point A. The shafts 13 and 14 perpendicular to the respective axes are secured adjacent to each other. The perpendicular angles of the holes 11, 12 and th113, 14 can be easily obtained based on the perpendicularity of the till and valley surfaces of the shape of the main body l.

The connector connector 2 has a cylindrical connector body 21 with a screw 22 carved on one side of the outside, and the other has an outer diameter flA @2a that fits the hole 11 or 12 of the connector body 1.Inner diameter A step 24 is provided on the screw 22 side and the opposite side,
The inner circumferential surface 25 is a hole into which an original fiber core, which will be described later, is inserted.

In the case of this embodiment, the carp and lid connector 2 described above are two identical ones.

The concave body 3 as an optical path deflector is a spherical body or an ellipsoid made of a transparent material with A-angle surfaces 31 and 32 formed thereon. Orthogonal direction: (An anti-reflection film is formed on 1 and 32.

As shown in Figure 3, the holes 1 in the carp lid body 1
1,124 is the correct position, insert the 1°kuku connector 2 (
press fit). One rectangle may be formed by press-fitting, but if a known anaerobic adhesive is applied in advance and If + 1 is added, insertion will be facilitated and fixation will be ensured.

Next, the concave body 3 is made to face the right angle surface 31.32 in the same way with respect to the right angle direction 13.14. The concave body 3 may be fixed by pressure using a mounting bracket, a spring, etc. (not shown), or may be fixed using an adhesive. After this, attach the cover 4 to cover it and protect it.

51. The end face of the main body 52 of the original fiber cutter 5 is pressed and fixed to the step 24 21. The axial position is determined by This means that the distance between the original fiber end face 53 and the surface 31 or 32 of the concave body 3 is constant. Further, the center of the circular concave surface 35 of the concave body coincides with the center of the hole 11, 12 and the intersection point A of the two axes of the connector connectors 2.

The original signal transmitted to the original fiber of one optical fiber connector 5 is emitted from the end face 53 at a divergence angle based on N-A, enters the concave body 3 from the surface 31, and enters the internal concave l'.
+! ] 35 and is deflected in the right angle direction, (L), and the other original fiber of the connector 5, which is pushed and glued, passes so as to converge toward the other fiber 32.
The light is converged on the surface 53 and transmitted through the original fiber. In addition, the rectangular part of the outer shape of the main body l in Fig. 3 is small, and the imaginary line part has been removed to reduce the weight without damaging the cAW. Since it is used to reduce the deflection distortion of the input path, it is also possible to divide the glass bulb into four parts as shown in Figure 4 Cal, and divide the ellipsoid into four parts. This can be easily obtained by forming a right-angled surface. Although the convergence of spheres cannot coincide at all, there is a difference in practical use, and an object with a focal point of 21 degrees, such as an ellipsoid, can perform efficient optical coupling. The dividing width B, which is equal to the length of the step 24 of the connector coupler 2 divided by the dividing width, can be made by using the cut ω of the sphere or the like as a polishing allowance.

A different concave body 3' (as shown in Fig. 131) has a concave curve 37 formed on the right-angled edge of the block and is provided with a reflective thI71-fish layer, etc., and the concave curve 37 corresponds to the concave curve 35 described above. However, since it is a space, there is no one-sided reflection or internal loss on the original body, so it is suitable.The convex curve 37 can be formed by cutting, cutting, grinding, etc. Also glass,
It may be made of ceramic, metal, or other non-metal, and since it is a block as a whole, it is easy to secure right-angled surfaces and to easily attach it to the connector body. The corners of the right-angled surfaces are rounded to 8+ sides to facilitate attachment to the connector body.

As described above, since the original connector according to the present invention directly deflects the optical path at right angles by interposing the optical fiber connector between one original fiber connector and the other optical fiber connector, the coupling can be performed in an extremely small space. Ru.

FIG. 5 is a side cross section of another embodiment of the present invention, which is a connector body 6 in which the connector body l and connector body 21 of the above embodiment are integrated, but the holes 61 and 62 are through holes. In this case, there is no step in this part of the hole because no step is formed inside.
The concave body 3/ in Figure (bl) is attached.Furthermore, the collar 54 of the optical fiber connector 5 abuts against the end face of the coil cover body and is tightened to position the connector body 6 in the axial direction. I visit Koi-futa in small quantities and for a relaxing stay.

ta+ figure for the one with the C-shaped nut 82 fitted, and tb1 for the one with the bag-shaped nut 81 fitted by the C-shaped hinge 82.
As shown in the figure. This is the case when the original fiber coil lid has a male thread engraved on the outer periphery, or an optical element with a similar shape.
For example, it is difficult to connect it to a light emitting unit and a light receiving unit.

(Effects of the 53rd Brother As mentioned above, the present invention Q) The original carp and the lid have each concave facing the optical axis of the connector main body as a right angle surface, and a concave body is provided in the optical path deflecting means. Therefore, the practical effects are remarkable, such as being extremely simple, achieving high fA characteristics and high degree of coverage, and making it possible to connect optical circuits in a limited space.
