This application is a U.S. National Phase of International Patent Application No. PCT/JP2017/040153 filed on Nov. 7, 2017, which claims priority benefit of Japanese Patent Application No. JP 2016-223743 filed in the Japan Patent Office on Nov. 17, 2016. Each of the above-referenced applications is hereby incorporated herein by reference in its entirety.
The present technology relates to an optical connector, an optical cable, and an electronic device. More particularly, the present technology relates to an optical connector or the like that can avoid danger due to light leakage at removal.
Recently, a larger transmission capacity has been requested along with increase in the amount of communication through the Internet or the like. It has been becoming difficult to achieve such a large transmission capacity with a conventional transmission scheme through a copper cable. Accordingly, studies have been made on optical communication with which a larger transmission capacity can be achieved.
Currently, a typically used optical cable employs what is called a physical contact (PC) scheme in which optical fibers are connected with each other in a connector. However, the PC scheme needs highly accurate adjustment for positioning of both optical fibers. Furthermore, at each connection of the optical fibers, both optical fibers need to be cleaned to avoid damage on the optical fibers due to dust and the like adhering to ends of the optical fibers. Further, in the PC scheme, to prevent connection defect at the gap between the leading ends of the optical fibers, it is essential to inject a refractive index adjuster into the gap. For these reasons, it is difficult for a general user to connect and remove optical fibers by the PC scheme.
A collimated light connection scheme has been disclosed as a method of solving these problems. In the collimated light connection scheme, a lens is mounted at the leading end of each optical fiber with their optical axes aligned, and an optical signal is transferred as parallel light between the facing lenses. When the collimated light connection scheme is employed, accuracy requirement on positioning between connectors of the optical fibers is relaxed. Further, in the collimated light connection scheme, the optical fibers are optically connected with each other in a non-contact manner, and thus adverse influence on transmission quality due to dust and the like between the optical fibers can be reduced, and no frequent and careful cleaning needs to be performed.
However, parallel light used in the collimated light connection scheme is unlikely to attenuate at distance from an emission portion in principle, and cannot satisfy laser beam standards such as IEC 60825-1 and IEC 60825-2, depending on the intensity thereof. Thus, a shutter is provided to an optical connector to shield the parallel light at disconnection.
Furthermore, Patent Document 1 discloses an optical connector to prevent laser hazard due to collimated light (parallel light). Specifically, Patent Document 1 discloses an optical connector for performing collimated light connection in which an optical fiber fixing part and a collimate lens are provided with two facing recess-protrusion structures. With this optical connector, at disconnection of the optical connector, the collimate lens is separated from the optical fiber fixing part, and the recess-protrusion structures scatter light from the optical fiber. At connection of the optical connector, the collimate lens is pressed and contacts the optical fiber fixing part through the two recess-protrusion structures, and thus parallel light is emitted.
Patent Document 1: Japanese Patent Laid-open No. 2013-64803
In the optical connector disclosed in Patent Document 1, the collimate lens is pressed and contacts the optical fiber fixing part through the two recess-protrusion structures even at disconnection, and thus collimated light can be emitted from the optical connector. Furthermore, the optical connector disclosed in Patent Document 1 needs a mechanism for moving the collimate lens away from and close to the optical fiber fixing part, for example, and thus has a complicated structure.
The present technology is intended to prevent laser hazard at disconnection with a simple structure.
According to the concept of the present technology, an optical connector includes:
a tubular connector exterior; and
a block that is incorporated on one end side of the connector exterior and in which a light emission portion or a light incident portion is mounted toward the other end side of the connector exterior, in which
the light emission portion or the light incident portion is mounted on the block so that an optical axis direction of the light emission portion or the light incident portion is tilted relative to a longitudinal direction of the connector exterior,

The light emission portion emits collimated light in accordance with light output from the light transmission path, and at least part of the emitted collimated light is incident on the light diffusion portion provided inside the connector exterior. For example, the block may include a lens through which the collimated light is emitted.
For example, the block may include alight direction change member configured to change, to the direction of the tilt, the direction of the light output from the light transmission path extending the longitudinal direction of the connector exterior. Furthermore, for example, the block may be provided with a maintaining portion that contacts a block of a mating connector to maintain a block interval at a particular distance.
In this manner, in the present technology, as a structure that tilts the optical axis direction of the light emission portion mounted on the block relative to the longitudinal direction of the connector exterior, at least part of light emitted from the light emission portion is incident on the light diffusion portion provided inside the connector exterior. Thus, the power of light exposed to the outside at disconnection can be reduced, and laser hazard can be prevented with a simple structure.
Furthermore, according to another concept of the present technology, an optical connector includes:

the light emission portion emits light condensed in accordance with light output from a light transmission path, and
at least part of the emitted light is incident on a light diffusion portion provided inside the connector exterior.
In the present technology, the block on which the light emission portion or the light incident portion is mounted toward the other end side of the connector exterior is incorporated on the one end side of the tubular connector exterior. The light emission portion or the light incident portion is mounted on the block so that the optical axis direction thereof is tilted relative to the longitudinal direction of the connector exterior.
The light emission portion emits light condensed in accordance with light output from the light transmission path, and at least part of the emitted light is incident on the light diffusion portion provided inside the connector exterior. For example, the block may include a lens through which the condensed light is emitted. Furthermore, for example, the block may include a light direction change member configured to change, to the direction of the tilt, the direction of the light output from the light transmission path extending the longitudinal direction of the connector exterior.
In this manner, in the present technology, as a structure that tilts the optical axis direction of the light emission portion mounted on the block relative to the longitudinal direction of the connector exterior, at least part of light emitted from the light emission portion is incident on the light diffusion portion provided inside the connector exterior. Thus, the power of light exposed to the outside at disconnection can be reduced, and laser hazard can be prevented with a simple structure.
Furthermore, according to another concept of the present technology, an optical connector includes:
a tubular connector exterior; and
a block that is incorporated on one end side of the connector exterior and in which a light emission portion or a light incident portion is mounted toward the other end side of the connector exterior, in which
the light emission portion or the light incident portion is mounted on the block so that an optical axis direction of the light emission portion or the light incident portion is tilted relative to a longitudinal direction of the connector exterior,
the light emission portion is a light emitting element configured to convert an electric signal into an optical signal, and
part of light emitted from the light emitting element is incident on a light diffusion portion provided inside the connector exterior.
In the present technology, the block on which the light emission portion or the light incident portion is mounted toward the other end side of the connector exterior is incorporated on the one end side of the tubular connector exterior. The light emission portion or the light incident portion is mounted on the block so that the optical axis direction thereof is tilted relative to the longitudinal direction of the connector exterior. The light emission portion is a light emitting element configured to convert an electric signal into an optical signal, and at least part of light emitted from the light emitting element is incident on the light diffusion portion provided inside the connector exterior.
In this manner, in the present technology, as a structure that tilts the optical axis direction of the light emission portion (light emitting element configured to convert an electric signal into an optical signal) mounted on the block relative to the longitudinal direction of the connector exterior, at least part of light emitted from the light emission portion is incident on the light diffusion portion provided inside the connector exterior. Thus, the power of light exposed to the outside at disconnection can be reduced, and laser hazard can be prevented with a simple structure.
Furthermore, according to another concept of the present technology, an optical connector includes:
a tubular connector exterior;
a block that is incorporated on one end side of the connector exterior and in which a light emission portion or a light incident portion is mounted toward the other end side of the connector exterior; and
a mirror structural body disposed on the other end side of the block and configured to change the direction of light emitted from the light emission portion to a direction tilted relative to a longitudinal direction of the connector exterior.
In the present technology, the block on which the light emission portion or the light incident portion is mounted toward the other end side of the connector exterior is incorporated on the one end side of the tubular connector exterior. The mirror structural body is disposed on the other end side of the block. In a case where the light emission portion is mounted on the block, the direction of light emitted from the light emission portion is changed to a direction tilted relative to the longitudinal direction of the connector exterior through the mirror structural body. Furthermore, in a case where the light incident portion is mounted on the block, the direction of light from a direction tilted relative to the longitudinal direction of the connector exterior is changed to the longitudinal direction of the connector exterior through the mirror structural body so that the light is incident on the light incident portion.
In this manner, in the present technology, the direction of light emitted from the light emission portion is tilted relative to the longitudinal direction of the connector exterior through the mirror structural body. Thus, light (laser beam) emitted from the light emission portion at disconnection can be emitted inside the connector exterior. Accordingly, the power of light exposed to the outside can be reduced, and laser hazard can be prevented with a simple structure.
Note that, in the present technology, for example, the light emission portion may be a light emitting element through which light collimated in accordance with light output from the light transmission path is emitted, through which light condensed in accordance with light output from the light transmission path is emitted, or that converts an electric signal into an optical signal, and at least part of light reflected by the mirror structural body may be incident on the light diffusion portion provided inside the connector exterior.
According to the present technology, laser hazard at disconnection can be prevented with a simple structure. Note that effects described in the present specification are merely exemplary and the present invention is not limited thereto, but may have additional effects.

[Exemplary Configuration of Electronic Device and Optical Cable]
The optical cable 200 includes an optical cable body 201 and an optical connector 10A as a plug. The optical cable 200 transmits an optical signal between the electronic device 100 and any other electronic device or a communication network such as the Internet.
Note that the electronic device 100 may be, for example, a mobile electronic device such as a cellular phone, a smartphone, a PHS, a PDA, a tablet PC, a laptop computer, a video camera, an IC recorder, a portable media player, an electronic organizer, an electronic dictionary, an electronic calculator, or a portable game machine, or another electronic device such as a desktop computer, a display device, a television receiver, a radio receiver, a video recorder, a printer, a car navigation system, a game machine, a router, a hub, or an optical line terminal end device (ONU). Alternatively, the electronic device 100 may be included in an electric product such as a refrigerator, a washing machine, a clock, an intercom, an air conditioning facility, a humidifier, an air cleaner, an illumination instrument, or a cooking instrument, or part or whole of a vehicle as described later.
“Exemplary Configuration of Optical Connector that Functions as Plug or Receptacle”
Optical connectors include an optical connector that functions as a plug and an optical connector that functions as a receptacle. Both optical connectors are engaged to achieve optical communication. In this example, the optical connector that functions as a plug and the optical connector that functions as a receptacle are both described, but it is clear that the opposite combination thereof function in a similar manner, and thus the description is given only on one combination.
The block 12A is incorporated on one end side of the connector exterior 11A. The lens 121A is mounted toward the other end side of the connector exterior 11A. The lens 121A is mounted on the block 12A while being tilted toward the center of the connector exterior 11A so that the optical axis direction thereof is tilted relative to the longitudinal direction of the connector exterior 11A. The lens 121A functions as a light emission portion in a case where an optical signal is transmitted, and the lens 121A functions as a light incident portion in a case where an optical signal is received.
Note that two lenses 121A are illustrated in the drawing, but the present technology is not limited to the configuration in the drawing, and lenses 121A in an optional number equal to or larger than one may be mounted on the block 12A in accordance with the number of light transmission paths 202A. For example, a lens array of lenses arrayed in the thickness direction (up-down direction in the drawing) and the width direction (direction perpendicular to the sheet of the drawing) of the optical connector 10A may be mounted on the block 12A.
In the case of functioning as a light emission portion, the lens 121A collimates and emits light (laser beam) output from the light transmission path 202A. In this case, the block 12A includes a light direction change member configured to change the direction of light output from the light transmission path 202A extending in the longitudinal direction of the connector exterior 11A to the optical axis direction of the lens 121A.
Furthermore, in the case of functioning as a light incident portion, the lens 121A condenses incident collimated light (laser beam) and inputs the light to the light transmission path 202A. In this case, the block 12A includes a light direction change member configured to change the direction of the light condensed through the lens 121A to the direction of the light transmission path 202A extending in the longitudinal direction of the connector exterior 11A. The light direction change member may be achieved by, for example, a light waveguide, a mirror structural body, or the like.
Furthermore,
Returning to
A light diffusion portion 111A is formed at a site of the connector exterior 11A on which the collimated light is incident. The light diffusion portion 111A may be any member that diffuses light, and may be, for example, a rough surface or a porous film such as an alumite layer. An alumite layer can be easily and inexpensively formed and has an excellent light diffusion property. In a case where the light diffusion portion 111A is an alumite layer, the connector exterior 11A includes aluminum.
Furthermore, a maintaining portion 122A for contact with a block of a mating connector is provided on the lens 121A side of the block 12A. The maintaining portion 122A maintains block connection with a maintaining portion similarly provided to the block of the mating connector at a particular distance (interval maintaining mechanism).
In addition, the connector exterior 11A is provided with a lock groove 1111A in which a lock spring is stored to hold engagement with the mating connector (optical connector that functions as a receptacle). The connector exterior 11A can be held at a particular position at engagement by the lock groove 1111A. This mechanism (lock mechanism) of the lock groove 1111A and the lock spring has a lock strength that is canceled by removal force of a certain magnitude.
The block 12B is incorporated on one end side of the connector exterior 11B. The lens 121B is mounted toward the other end side of the connector exterior 11B. The lens 121B is mounted on the block 12B while being tilted toward the center of the connector exterior 11B so that the optical axis direction thereof is tilted relative to the longitudinal direction of the connector exterior 11B. The lens 121B functions as a light emission portion in a case where an optical signal is transmitted therethrough, and the lens 121B functions as a light incident portion in a case where an optical signal is received therethrough.
Note that the two lenses 121B are illustrated in the drawing, but the present technology is not limited to the configuration in the drawing, and lenses 121B in an optional number equal to or larger than one may be mounted on the block 12B in accordance with the number of light transmission paths 202B. For example, a lens array of lenses arrayed in the thickness direction (up-down direction in the drawing) and the width direction (direction perpendicular to the sheet of the drawing) of the optical connector 10B may be mounted on the block 12B.
In the case of functioning as a light emission portion, the lens 121B collimates and emits light (laser beam) output from a light transmission path 202B. In this case, the block 12B includes a light direction change member configured to change the direction of light output from the light transmission path 202B extending in the longitudinal direction of the connector exterior 11B to the optical axis direction of the lens 121B.
Furthermore, in the case of functioning as a light incident portion, the lens 121B condenses incident collimated light (laser beam) and inputs the light to the light transmission path 202B. In this case, the block 12B includes a light direction change member configured to change the direction of light condensed through the lens 121B to the direction of the light transmission path 202B extending in the longitudinal direction of the connector exterior 11B.
Although not described in detail, similarly to the case of the optical connector 10A described above, the light direction change member is achieved by a light waveguide or a mirror structural body (refer to
The connector exterior 11B has such a length that at least part of collimated light (laser beam) LB1 emitted from the lens 121B functioning as the emission portion is incident on the inside (inner wall) thereof. Specifically, in this case, at least part of the collimated light emitted from the lens 121B is incident on the inside (inner wall) of the connector exterior 11B and diffused. In the example illustrated in the drawing, the whole light is incident on the inside. Accordingly, laser hazard at removal is prevented. In other words, the power of an optical signal exposed from the optical connector 10A is sufficiently reduced so that safety standard is satisfied.
A light diffusion portion 111B is formed at a site of the connector exterior 11B on which collimated light is incident. The light diffusion portion 111B may be any member that diffuses light and may be, for example, a rough surface or a porous film such as an alumite layer. An alumite layer can be easily and inexpensively formed and has an excellent light diffusion property. In a case where the light diffusion portion 111B is an alumite layer, the connector exterior 11B includes aluminum.
Furthermore, a maintaining portion 122B for contact with a block of a mating connector is provided on the lens 121B side of the block 12B. This maintaining portion 122B maintains block connection with a maintaining portion similarly provided to the block of the mating connector at a particular distance (interval maintaining mechanism).
In addition, the connector exterior 11B is provided with a lock spring 1111B stored in a lock groove to hold engagement with the mating connector (optical connector that functions as a plug). The connector exterior 11B can be held at a particular position against pressing force of a spring as described later at engagement by the lock spring 1111B. This mechanism (lock mechanism) of the lock spring 1111B and the lock groove has a lock strength that is canceled by removal force of a certain magnitude.
Furthermore, the block 12B is installed in a state (floating state) movable in the longitudinal direction in the connector exterior 11B, and pressed toward an opening end by a spring 2022B (pressing mechanism). In this case, the block 12B is pressed toward the mating connector side at the start of contact with the block of the mating connector. Accordingly, at engagement, the contact with the block of the mating connector can be excellently maintained even in a situation such as wrench or insufficient insertion. Note that movement of the block 12B toward the opening end is regulated when a regulative protrusion 123B provided to the block 12B contacts a regulative recess 124B of the connector exterior 11B.
In the example illustrated in the drawing, for example, the lens 121B of the optical connector 10B functions as a light emission portion, and the lens 121A of the optical connector 10A functions as a light incident portion. The collimated light LB1 emitted from the lens 121B mounted on the lower side in the optical connector 10B in the drawing is incident on the lens 121A mounted on the upper side in the optical connector 10A in the drawing. Furthermore, the collimated light LB1 emitted from the lens 121B mounted on the upper side in the optical connector 10B in the drawing is incident on the lens 121A mounted on the lower side in the optical connector 10A in the drawing.
Note that similar description applies to an example in which the lens 121A of the optical connector 10A functions as a light emission portion, and the lens 121B of the optical connector 10B functions as a light incident portion. Furthermore, similar description applies to an example in which part of a plurality of lenses 121A of the optical connector 10A functions as a light emission portion and the other part thereof functions as a light incident portion, whereas part of a plurality of lenses 121B of the optical connector 10B functions as a light incident portion and the other part thereof functions as the light emission portion.
Furthermore, the lock spring 1111B of the optical connector 10B is engaged with the lock groove 1111A of the optical connector 10A, and the optical connector 10A and the optical connector 10B are fixed at an engagement distance in a communicable manner. This engagement is easily canceled by removal at strength of a certain magnitude.
As described above, in the optical connectors 10A and 10B illustrated in
Furthermore, the block 12B of the optical connector 10B illustrated in

Such an optical cable 200 can be used in connection for optical communication between an electronic device such as the electronic device 100 described above and another instrument.
“Another Exemplary Configuration of Optical Connector that Functions as Plug or Receptacle”
The following describes another exemplary configuration of an optical connector that functions as a plug or a receptacle. Note that illustration and thus description of the pressing mechanism, the lock mechanism, and the block interval maintaining mechanism will be omitted in this exemplary configuration. This is similar in another exemplary configuration.
The block 22A is incorporated on one end side of the connector exterior 21A. The optical element 221A is mounted toward the other end side of the connector exterior 21A. The optical element 221A is mounted on the block 22A while being tilted toward the center of the connector exterior 21A so that the optical axis direction thereof is tilted relative to the longitudinal direction of the connector exterior 21A.
Note that the two optical elements 221A are illustrated in the drawing, but the present technology is not limited to the configuration in the drawing, and optical elements 221A in an optional number equal to or larger than one may be mounted on the block 22A in accordance with the number of electricity transmission paths 202A′. For example, an optical element array of optical elements arrayed in the thickness direction (up-down direction in the drawing) and the width direction (direction perpendicular to the sheet of the drawing) of the optical connector 20A may be mounted on the block 22A. Note that each electricity transmission path 202A′ replaces the above-described light transmission path 202A.
The optical element 221A is a light emitting element that functions as a light emission portion in a case where an optical signal is transmitted therethrough, and converts an electric signal transferred through the electricity transmission path 202A′ into an optical signal (laser beam) and emits the optical signal. The optical element 221A is a light receiving element that functions as a light incident portion in a case where an optical signal is received therethrough, and converts an incident optical signal (laser beam) into an electric signal and transfers the electric signal to the electricity transmission path 202A′.
The connector exterior 21A has such a length that at least part of light (laser beam) LA2 emitted from the optical element 221A functioning as a light emission portion is incident on the inside (inner wall) thereof. Specifically, in this case, at least part of the light LA2 emitted from the optical element 221A is incident on the inside (inner wall) of the connector exterior 21A and diffused. In the example illustrated in the drawing, part thereof is incident. Accordingly, laser hazard at removal is prevented.
A light diffusion portion 211A is formed at a site of the connector exterior 21A on which the laser beam is incident. The light diffusion portion 211A may be any member that diffuses light and may be, for example, a rough surface or a porous film such as an alumite layer. An alumite layer can be easily and inexpensively formed and has an excellent light diffusion property.
