Description

  The present invention relates to an optical connector, an optical wiring component, an optical connector, and an electronic device.

  Replacing electrical wiring with optical wiring is expected to increase communication speed, increase capacity, and reduce power consumption.

  An optical waveguide is used as an optical wiring for optical communication over a relatively short distance such as communication between boards in an electronic device.

  When assembling such an electronic device, an operation of connecting the optical waveguides is included. In this operation, the efficiency of the operation of connecting the optical waveguides can be increased by using the optical connector. Specifically, an optical waveguide with a connector in which an optical connector is attached to the end of the optical waveguide is used. Then, the optical waveguides are optically connected by abutting the connectors. Thereafter, the optical connection is completed by fastening the connectors together.

  Patent Document 1 discloses that the optical connector is connected and fixed by using a clamp spring after the end surfaces of the optical connectors face each other and the optical connection surfaces of the strip-shaped optical waveguide are brought into contact with each other. ing. The clamp springs engage with the outer surfaces of the two optical connectors, respectively, and urge them in a direction to bring them closer to each other.

JP 2012-113177 A

  Since a sufficient elastic force is required for the clamp spring, for example, a metal spring is used. Since the metal spring is made by bending a thin metal plate, the end face is sharp and is easily scratched when touching a soft object. For example, when the clamp spring is attached to the optical connector, if the position of the clamp spring is shifted, it may hit the optical waveguide. At this time, if the optical waveguide is scratched, the transmission efficiency of the optical waveguide is lowered, and the reliability may be lowered.

  DESCRIPTION OF EMBODIMENTS Hereinafter, an optical connector, an optical wiring component, an optical connector, and an electronic device according to the present invention will be described in detail based on preferred embodiments shown in the accompanying drawings.

<< First Embodiment >>
<Optical connector>
First, the first embodiment of the optical connector of the present invention, the first embodiment of the optical wiring component of the present invention included therein, and the first embodiment of the optical connector of the present invention included therein will be described. .

  1 and 2 are side views showing how the first embodiment of the optical connector of the present invention is manufactured by connecting the first embodiment of the optical wiring component of the present invention and the optical component of the connection partner. is there. FIG. 3 is a side view showing the first embodiment of the optical connector of the present invention produced as shown in FIGS.

  An optical wiring component 10 shown in FIG. 1 includes an optical waveguide 1 and an optical connector 5 (an embodiment of the optical connector of the present invention) provided at an end of the optical waveguide 1. The optical waveguide in the present invention is not only an optical transmission member made of, for example, a polymer, glass, or silicon and formed into a sheet shape, but also a plurality of polymers or glass, for example. It also includes an optical fiber array in which optical fibers are bundled in a band shape.

  On the other hand, the optical wiring component 9 shown in FIG. 1 is an optical component to which the optical wiring component 10 is connected. The optical wiring component 9 shown in FIG. 1 is an optical waveguide with a connector having an optical waveguide 91 and an optical connector 92 provided at the end thereof, but the optical component to be connected is not limited to this, and the optical wiring Any optical component that can be optically connected to the component 10 may be used. For example, an optical fiber with a connector or a light emitting / receiving element may be used.

  A guide pin 81 is used for positioning the optical wiring component 10 and the optical wiring component 9. The guide pins 81 are inserted into both guide holes provided in the optical connector 5 of the optical wiring component 10 and guide holes provided in the optical connector 92 of the optical wiring component 9. Thereby, alignment (alignment) of the optical wiring component 10 and the optical wiring component 9 can be performed. This alignment means that the light incident / exit surface (generally, the end surface) of the optical waveguide 1 and the light incident / exit surface of the optical waveguide 91 are abutted (the optical axis is aligned).

  By connecting the optical wiring component 10 and the optical wiring component 9 in this manner, the optical waveguide 1 and the optical waveguide 91 are optically connected.

In this state, since the connection state between the optical connector 5 and the optical connector 92 cannot be maintained, it is necessary to apply an external force and press the optical connector 5 and the optical connector 92 together.
Therefore, a clamp spring 82 shown in FIG. 2 is attached.

  The clamp spring 82 shown in FIG. 2 includes a flat plate portion 821 and a pair of bent portions 822a and 822b provided at both ends of the flat plate portion 821. The bent portions 822a and 822b are bent toward one surface side of the flat plate portion 821, respectively. When an external force is applied so that the bent portion 822a and the bent portion 822b are separated from each other, a repulsive force is generated in a direction in which the bent portion 822a and the bent portion 822b approach each other due to the spring elasticity of the clamp spring 82.

  Therefore, when the optical connector 5 and the optical connector 92 are disposed between the bent portion 822a and the bent portion 822b as shown by the white arrows in FIG. 2, the optical connector 5 is caused by the repulsive force of the bent portion 822a and the bent portion 822b. The external force is continuously applied in the direction in which the optical connector 92 and the optical connector 92 are pressed together.

  As a result, the optical connector 100 shown in FIG. 3 is obtained. In such an optical connector 100, the optical connector 5 and the optical connector 92 are pressed (fastened) to each other by the action of the clamp spring 82, and accordingly, the optical waveguide 1 and the optical waveguide 91 are pressed to each other. For this reason, it becomes difficult to produce a clearance gap between the optical waveguide 1 and the optical waveguide 91, and the optical coupling loss is reduced.

  In addition, as a constituent material of the guide pin 81, a metal material, a ceramic material, a resin material etc. are mentioned, for example.

  On the other hand, examples of the constituent material of the clamp spring 82 include a metal material and a resin material.

<Optical wiring parts>
Next, the optical wiring component 10 will be described.

  FIG. 4 is a perspective view showing how the first embodiment of the optical connector of the present invention shown in FIG. 2 is produced. FIG. 5 is a perspective view of the optical connector 100 shown in FIG. FIG. 6 is a cross-sectional view of the optical wiring component 10 shown in FIG.

  The optical wiring component 10 shown in FIG. 4 has the optical waveguide 1 and the optical connector 5 provided at the end of the optical waveguide 1 as described above.

(Optical connector)
The optical connector 5 includes a connector main body 51 and a through hole 50 (through part) formed in the connector main body 51. And the front-end | tip part 101 of the optical waveguide 1 is inserted in this through-hole 50. FIG.

  The right end surface of the optical connector 5 in FIG. 6 is a surface facing the optical wiring component 9 when the optical wiring component 10 is connected to the optical wiring component 9. In the present specification, the right end surface of the optical connector 5 is referred to as “opposing surface 52”, and the left end surface is referred to as “non-facing surface 53”.

  The through hole 50 is formed so as to penetrate the opposing surface 52 (first outer surface) and the non-facing surface 53 (second outer surface) of the connector main body 51. Moreover, the through-hole 50 is comprised so that it may have a cut surface which makes a rectangle, when cut | disconnected along the direction orthogonal to the longitudinal direction.

  The outer shape of the connector body 51 is not particularly limited, and may be a shape conforming to a rectangular parallelepiped as shown in FIG. 4 or other shapes. Further, the connector main body 51 may include a part conforming to various connector standards. Examples of such connector standards include a miniature MT connector, an MT connector specified in JIS C 5981, a 16MT connector, a two-dimensional array MT connector, an MPO connector, and an MPX connector.

  Further, as shown in FIG. 4, the connector main body 51 is formed with a guide hole 511a (first clamp mounting portion) and a guide hole 511b (second clamp mounting portion). The guide holes 511a and 511b are opened in the facing surface 52 and the non-facing surface 53 of the connector body 51, respectively. That is, the two guide holes 511a and 511b penetrate through the opposing surface 52 and the non-facing surface 53, respectively.

  The guide hole 511 a and the guide hole 511 b are provided at positions opposite to each other through the through hole 50.

  The guide pins 81 described above are inserted into the guide holes 511a and 511b when the optical wiring component 10 is connected to the optical wiring component 9 (see FIG. 1).

  In addition, among the guide holes 511a and 511b, a part of the bent portions 822a and 822b of the clamp spring 82 described above is inserted into the opening on the non-facing surface 53 side (see FIG. 5). That is, the opening on the non-facing surface 53 side of the guide hole 511a and the guide hole 511b becomes a first clamp mounting part and a second clamp mounting part for mounting the clamp spring 82. Since the clamp spring 82 is attached only by fitting (engaging) the bent portions 822a and 822b to the guide holes 511a and 511b, the attaching operation is facilitated. In this way, the clamp spring 82 is fixed to the optical connector 5, and the clamp spring 82 is less likely to be displaced with respect to the optical connector 5, so that the fastened state is more reliably maintained.

  The cross-sectional shape of the through hole 50 (cut surface shape in a direction orthogonal to the line connecting the openings) is not limited to the rectangle as described above, and may be a square, a parallelogram, a hexagon, an eight Other shapes such as a square shape and an oval shape may be used.

  Further, in the optical connector 5 shown in FIG. 6, the height and width of the through hole 50 are constant, but the height gradually increases from the facing surface 52 side toward the non-facing surface 53 side. Also good.

  Examples of the constituent material of the connector body 51 include various resin materials such as phenol resin, epoxy resin, olefin resin, urea resin, melamine resin, unsaturated polyester resin, polyphenylene sulfide resin, stainless steel, and the like. And various metal materials such as an aluminum alloy.

  The distal end portion 101 of the optical waveguide 1 is bonded to the lower surface 501 and the upper surface 502 of the through hole 50 via the adhesive 6. That is, the optical waveguide 1 is placed on the lower surface 501 and the upper surface 502. Thereby, the optical waveguide 1 is fixed in a state of being inserted into the through hole 50. As a result, the optical waveguide 1 can be protected from external force and the like, so that the optical waveguide 1 can be easily grasped and the reliability of the optical wiring component 10 can be increased.

  In the present specification, the portion of the lower surface 501 of the through hole 50 where the optical waveguide 1 is mounted is particularly referred to as a “mounting surface 501a”. Similarly, a portion of the upper surface 502 of the through hole 50 where the optical waveguide 1 is mounted is particularly referred to as a “mounting surface 502a”.

Next, the optical connector 5 will be described in detail.
FIG. 7 is a diagram when the non-facing surface 53 of the connector main body 51 in the optical connector 100 shown in FIG. 5 is viewed in plan. 8 is a cross-sectional view taken along line AA in FIG. FIG. 9 is a view showing the optical wiring component 10 shown in FIG. 7 except for the protruding portions 54a and 54b.

  In the optical connector 100, as shown in FIG. 5, the optical connector 5 and the optical connector 92 are fastened by a clamp spring 82. At this time, as shown in FIG. 8, a part of the bent portion 822a of the clamp spring 82 is inserted into the guide holes 511a and 511b. Although not shown, a part of the bent portion 822b is inserted into a guide hole provided in the optical connector 92. In this way, a part of the bent portion 822a of the clamp spring 82 enters the guide holes 511a and 511b, so that displacement in the non-facing surface 53 is restricted. As a result, the fastened state is maintained.

  In order to move the bent portion 822a of the clamp spring 82 to the guide holes 511a and 511b, for example, as shown in FIG. 4, the clamp spring 82 is approached from one main surface side (downward in FIG. 4) of the optical waveguide 1. The bent portion 822a is placed on the non-facing surface 53 and slid to the guide holes 511a and 511b. When the bent portion 822a is on the non-facing surface 53, the bent portion 822a and the bent portion 822b of the clamp spring 82 are separated from each other, while a repulsive force is generated in a direction in which the bent portion 822a and the bent portion 822b approach each other. To do.

When the bent portion 822a reaches the guide holes 511a and 511b, a part of the bent portion 822a falls into the guide holes 511a and 511b. Thereby, based on the repulsive force mentioned above, it deform | transforms so that the bending part 822a and the bending part 822b may mutually approach. As a result, the bent portion 822a is engaged with the guide holes 511a and 511b, and the subsequent displacement is restricted.
Such a fastening operation is often performed, for example, manually by an operator.

  However, when the operator makes a mistake in applying force, the bent portion 822a may slide in the wrong direction. At this time, the bent portion 822a may come into contact with the optical waveguide 1. Since the clamp spring 82 is normally made of a metal material, it has a high hardness. For this reason, the optical waveguide 1 may be damaged by the edge of the clamp spring 82, and the optical transmission property of the optical waveguide 1 may be impaired.

  Therefore, the optical connector 5 according to the present embodiment includes projecting portions 54a and 54b that project from the non-facing surface 53 of the connector main body 51, as shown in FIG. 7 and 9, for the convenience of illustration, relatively dense dots are attached to the optical waveguide 1, and in FIG. 7, relatively sparse dots are attached to the protrusions 54a and 54b. In FIG. 9, the protrusions 54a and 54b are not shown. 7 and 9, the extending direction of the line segment connecting the guide hole 511a and the guide hole 511b is the X axis direction, and the direction orthogonal to the X axis in the non-facing surface 53 is the Y axis direction. .

  Among these, as shown in FIG. 7, the protruding portion 54a is formed between the mounting surfaces 501a and 502a and the guide hole 511a (first clamp mounting portion) when the non-facing surface 53 (second outer surface) is viewed in plan. It is provided in the area between. On the other hand, as shown in FIG. 7, the protruding portion 54b is provided in a region between the placement surfaces 501a and 502a and the guide hole 511b (second clamp mounting portion). By providing such protrusions 54a and 54b, even when an operator who wears the clamp spring 82 accidentally slides the bent portion 822a toward the optical waveguide 1, the bent portion 822a is attached to the optical waveguide 1. Contact can be prevented. In other words, the bent portion 822a cannot be moved further to the optical waveguide 1 side by being blocked by the protruding portions 54a and 54b. For this reason, it is possible to prevent the optical waveguide 1 and the bent portion 822a from coming into contact with each other, and to prevent the optical waveguide 1 from being damaged.

  Therefore, when the optical connector 5 is mounted on the optical waveguide 1 and the optical wiring component 10 is obtained, the optical connector 100 formed by connecting the optical wiring component 10 and the optical wiring component 9 is made highly reliable. It becomes feasible.

  As described above, the protrusion 54a according to the present embodiment is provided in a region between the placement surfaces 501a and 502a and the guide hole 511a when the non-facing surface 53 is viewed in plan view. May be a region including at least a part of the “first boundary portion 531a” indicated by hatching in FIG. That is, the region where the protruding portion 54a is provided may be a region including the entire first boundary portion 531a or a region including only a part of the first boundary portion 531a.

  The first boundary portion 531a refers to a region located between the placement surfaces 501a and 502a and the guide hole 511a when the non-facing surface 53 is viewed in plan. More specifically, it refers to a region between the placement surfaces 501a and 502a and the guide hole 511a in the X-axis direction and the entire area of the non-facing surface 53 in the Y-axis direction. By providing the protruding portion 54a at the first boundary portion 531a, unintentional movement of the bent portion 822a toward the optical waveguide 1 can be prevented.

  On the other hand, the protruding portion 54b according to the present embodiment is also a region including at least a part of the “second boundary portion 531b” indicated by hatching in FIG. 9 when the non-facing surface 53 is viewed in plan as described above. That's fine. That is, the region where the protruding portion 54b is provided may be a region including the entire second boundary portion 531b or a region including only a part of the second boundary portion 531b.

  Note that the second boundary portion 531b is also a region located between the placement surfaces 501a and 502a and the guide hole 511b when the non-facing surface 53 is viewed in plan. More specifically, it refers to a region between the placement surfaces 501a and 502a and the guide hole 511b in the X-axis direction and the entire area of the non-facing surface 53 in the Y-axis direction. By providing the projecting portion 54b at the second boundary portion 531b, unintentional movement of the bent portion 822a toward the optical waveguide 1 can be prevented.

  Further, as shown in FIG. 7, the protrusions 54 a and 54 b according to the present embodiment are provided over the entire area in the Y-axis direction of the non-facing surface 53, but are provided only in a part in the Y-axis direction. May be. In the latter case, it is preferable that the protruding portions 54a and 54b are located on the line segment connecting the guide hole 511a and the guide hole 511b in the first boundary portion 531a and the second boundary portion 531b. Thereby, the optical waveguide 1 can be protected more reliably.

  Further, either one of the protrusions 54a and 54b may be omitted. In addition, by providing the protruding portion 54a on the first boundary portion 531a and providing the protruding portion 54b on the second boundary portion 531b, the bending portion 822a is prevented from being displaced from both the guide hole 511a and the guide hole 511b. Both ends of the width of the optical waveguide 1 can be protected from damage. For this reason, the optical connection body 100 with higher reliability is obtained.

  The width (length in the X-axis direction) of the protrusions 54a and 54b is not particularly limited, but is appropriately determined in consideration of the constituent materials and the like so as to have a mechanical strength that does not damage even if pressed by the bent portion 822a. Is set. As an example, although it depends on the size of the optical connector 5, it is preferably 0.3 mm or more, and more preferably 0.5 mm or more and 100 mm or less.

  Further, the height h (see FIG. 6) of the protrusions 54a and 54b is appropriately set in consideration of a balance with a decrease in mechanical strength, although it is more likely that the height is as high as possible. As an example, it is preferably 0.3 mm or more and 10 mm or less, and more preferably 0.5 mm or more and 5 mm or less. Thereby, the optical waveguide 1 can be sufficiently protected by the protrusions 54a and 54b, and a decrease in the mechanical strength of the protrusions 54a and 54b can be suppressed.

  The width of the through hole 50 (length in the X-axis direction) may be the same as the width of the optical waveguide 1 (length in the X-axis direction), but is set wider than the width of the optical waveguide 1. Is preferred. Thereby, a gap can be provided between the side surface of the distal end portion 101 of the optical waveguide 1 and the inner surface of the through hole 50. As a result, the adhesive 6 can be allowed to protrude into this space. As a result, the overflowing adhesive 6 can be prevented from entering the light incident / exit surface of the optical waveguide 1.

  The guide holes 511a and 511b can be aligned by inserting the guide pins 81, but the guide holes 511a and 511b engage with alignment mechanisms other than the guide pins 81 and the guide holes 511a and 511b, for example, the outer surfaces of each other. May be replaced by an alignment mechanism.

  Further, the guide holes 511a and 511b are also used as clamp mounting portions for mounting the clamp springs 82, respectively, but the structure of the clamp mounting portions is not limited to this. For example, a recess formed by recessing a part of the non-facing surface 53 can also be a clamp mounting portion.

  The clamp spring 82 can also be replaced by other clamps, for example, clamps that are fastened using screws or locking with claws.

  Since the optical wiring component 10 including the optical connector 5 and the optical waveguide 1 as described above is connected to the optical wiring component 9 using the clamp spring 82, the optical waveguide 1 is prevented from being damaged. A high optical connector 100 is obtained.

  Further, the optical wiring component 10 and the optical wiring component 9 are brought closer to each other by engaging with the optical wiring component 10, the optical wiring component 9 as an example of the optical component to be connected, and the guide holes 511 a and 511 b. Thus, the optical connector 100 having the clamp spring 82 fastened as described above has high optical transmission efficiency and optical coupling efficiency and high reliability.

(Modification)
FIG. 10 is a view showing a modification of the optical wiring component 10 and the optical connector 5 shown in FIG. This modified example is the same as the optical wiring component 10 and the optical connector 5 shown in FIG. 7 except for the following matters.

  As shown in FIG. 10, the optical connector 5 according to the present modification has a groove 50 ′ (through portion) except that the upper surface 502 side (see FIG. 6) of the through hole 50 shown in FIG. 7 is removed. This is the same as the optical connector 5 shown in FIG.

  The groove 50 ′ is also formed so as to penetrate the opposing surface 52 (first outer surface) and the non-opposing surface 53 (second outer surface) of the connector main body 51, similarly to the through hole 50.

Further, although not shown, the groove 50 ′ may be closed with a lid as necessary, and as a result, may be the same as the through hole 50.
Similar effects can be obtained in the above-described modified example.

In FIG. 11, the same reference numerals are given to the same configurations as those in the above-described embodiment.

  The optical connector 5 according to the second embodiment is the same as the optical connector 5 according to the first embodiment except that the shape of the protruding portion is different.

The optical connector 5 shown in FIG. 11 includes protrusions 54c and 54d.
Among these, the protrusion part 54c is provided in the area | region covering both the 1st boundary part 531a and the 2nd boundary part 531b among the non-facing surfaces 53. FIG. Such a protrusion 54 c is located on the upper surface 502 side of the through hole 50 in the non-facing surface 53.

  On the other hand, the projecting portion 54d is also provided in a region of the non-facing surface 53 that extends over both the first boundary portion 531a and the second boundary portion 531b. The protruding portion 54 d is located on the lower surface 501 side of the through hole 50 in the non-facing surface 53.

  Thus, since the protrusion parts 54c and 54d are provided in the area | region containing both the 1st boundary part 531a and the 2nd boundary part 531b, respectively, the area can be ensured sufficiently wide. For this reason, since the mechanical strength of the protrusions 54c and 54d is increased, the protrusions 54c and 54d are less likely to be damaged even when the optical connector 5 is small.

  Further, by providing it in a region that spans both the first boundary portion 531a and the second boundary portion 531b, the guide hole 511a (first clamp mounting portion) and the guide hole 511b (second clamp mounting portion) can be formed by one protrusion 54c. ) Can be prevented from shifting from both sides, and both ends of the width of the optical waveguide 1 can be protected from damage. For this reason, simplification of the structure of the protrusion part 54c is achieved, and manufacture of the optical connector 5 becomes easy.

  In other words, the protrusions 54c and 54d are provided in two regions arranged in the Y-axis direction via the through hole 50, respectively. Since the through-hole 50 shown in FIG. 11 has a shape having a long axis in the X-axis direction, a wide space is generated on both sides in the Y-axis direction across the through-hole 50 in the non-facing surface 53. For this reason, by arranging the protrusions 54c and 54d in this space, it is possible to secure a large area for each of the protrusions 54c and 54d. As a result, the mechanical strength of the protrusions 54c and 54d becomes higher, and the protrusions 54c and 54d are less likely to be damaged.

  The protrusions 54c and 54d are provided so as to cover the optical waveguide 1 in the width direction. For this reason, even when the optical waveguide 1 is bent to one of the principal surfaces, it is possible to suppress the occurrence of a sudden bending that causes damage. That is, when the optical waveguide 1 is bent, the optical waveguide 1 hits one of the projecting portions 54c and 54d, thereby suppressing further bending. As a result, it is possible to prevent the optical waveguide 1 from being damaged.

In addition, although the space | interval of the protrusion part 54c and the protrusion part 54d may be fixed as shown in FIG. 11, you may change partially. For example, the interval may gradually change along the extending direction of the optical waveguide 1 (the thickness direction in FIG. 11).
Further, either one of the projecting portions 54c and 54d may be omitted.

  Moreover, the length in the Y-axis direction of the protrusions 54c and 54d is not particularly limited, and may be shorter than the length shown in FIG.

Further, in addition to the protrusions 54c and 54d, another protrusion may be provided. For example, the protrusion 54c or the protrusion 54d may be divided into a plurality in the X-axis direction or the Y-axis direction, and as a result, the number of protrusions may increase.
In the second embodiment as described above, the same effect as in the first embodiment can be obtained.
