Abstract

An optical data transmission can be performed satisfactorily. The connector includes an electrode provided at a position corresponding to the electrode of the mating connector and an optical section provided at a position corresponding to the optical section of the mating connector. When the mating with the mating connector is performed, the electrode comes into contact with the electrode of the mating connector after the optical section has contacted the optical section of the mating connector. When the mating with the mating connector is released, the optical part is separated from the optical part of the mating connector after the electrode is separated from the electrode of the mating connector.

Description

  The present technology relates to a connector, an electronic device, and an electronic device control method, and more particularly to a connector for optical data transmission.

  In recent years, it has been proposed to perform optical data transmission with a rapid increase in communication capacity (see Patent Document 1). When performing optical data transmission, transmission with strong power is required to improve transmission quality, but securing safety when the connector is disconnected becomes a problem.

Japanese Patent Laid-Open No. 2003-043296

  An object of the present technology is to enable good optical data transmission.

The concept of this technology is
An electrode provided at a position corresponding to the electrode of the mating connector;
An optical unit provided at a position corresponding to the optical unit of the mating connector,
When the mating with the mating connector is performed, the electrode contacts the electrode of the mating connector after the optical section contacts the optical section of the mating connector,
When the fitting with the mating connector is released, the optical portion is in the connector separated from the optical portion of the mating connector after the electrode is separated from the electrode of the mating connector.

  In the present technology, the connector is provided with an electrode at a position corresponding to the electrode of the mating connector, and an optical section at a position corresponding to the optical section of the mating connector. And when the mating with the mating connector is performed, the electrode comes into contact with the electrode of the mating connector after the optical section comes into contact with the optical section of the mating connector, and when the mating with the mating connector is released, The optical part is separated from the optical part of the mating connector after being separated from the electrode of the mating connector.

  For example, the optical unit is movably provided, and in a state where the optical unit starts contact with the optical unit of the mating connector, the optical unit is placed on the mating connector side so that the electrode is in a position separated from the electrode of the mating connector. An urging unit for urging may be further provided. In this case, for example, a lock unit that holds the state in which the electrode is in contact with the electrode of the mating connector against the urging force of the urging unit may be further provided.

  As described above, in the present technology, when the mating with the mating connector is performed, the electrode is brought into contact with the electrode of the mating connector after the optical unit is brought into contact with the optical unit of the mating connector and the mating with the mating connector. When the release is performed, the optical part is separated from the optical part of the mating connector after the electrode is separated from the electrode of the mating connector. Therefore, when the electrode is in contact with the electrode of the mating connector, it is guaranteed that the optical section is in contact with the optical section of the mating connector. Only in this case, the power of the optical signal supplied to the optical section is controlled to be high. By doing so, safety can be ensured, and optical data transmission can be performed well.

Other concepts of this technology are
An electrode provided at a position corresponding to the electrode of the mating connector, and a connector having an optical section provided at a position corresponding to the optical section of the mating connector;
A transmission unit that converts transmission data into an optical signal and supplies the optical signal to the optical unit;
A detection unit for detecting presence or absence of contact between the electrode and the electrode of the mating connector based on a signal obtained from the electrode;
The electronic apparatus includes a control unit that controls power of an optical signal supplied from the transmission unit to the optical unit based on an output of the detection unit.

  In the present technology, the electronic device includes a connector having an electrode provided at a position corresponding to the electrode of the mating connector and an optical section provided at a position corresponding to the optical section of the mating connector. Transmission data is converted into an optical signal by the transmission unit and supplied to the optical unit. The detection unit detects the presence or absence of contact between the electrode and the electrode of the mating connector based on a signal obtained from the electrode. The control unit controls the power of the optical signal supplied from the transmission unit to the optical unit based on the output of the detection unit.

  For example, when the connector is mated with the mating connector, the electrode contacts the electrode of the mating connector after the optical section contacts the optical section of the mating connector, and the mating with the mating connector is released. The optical part may be separated from the optical part of the mating connector after the electrode is separated from the electrode of the mating connector.

  In this case, for example, the optical unit is movably provided, and the connector is optically positioned so that the electrode is not in contact with the electrode of the mating connector in a state where the optical unit starts to contact the optical unit of the mating connector. A biasing portion that biases the portion toward the mating connector may be further included. In this case, for example, the connector may further include a lock portion that holds the state in which the electrode is in contact with the electrode of the mating connector against the urging force of the urging portion.

  For example, the control unit controls the power of the optical signal to the first power when the output of the detection unit indicates that there is contact between the electrode and the electrode of the mating connector, and the output of the detection unit is the electrode and the mating connector. The power of the optical signal may be controlled to a second power lower than the first power when it indicates that there is no contact with the electrode.

  As described above, in the present technology, the power of the optical signal supplied from the transmission unit to the optical unit is controlled based on the detection output of the presence or absence of contact between the electrode and the electrode of the mating connector. Therefore, only when the optical unit is in contact with the optical unit of the mating connector, the power of the optical signal can be increased, safety can be ensured, and optical data transmission can be performed satisfactorily.

  According to the present technology, optical data transmission can be performed satisfactorily. The effects described in this specification are merely examples and are not limited, and may have additional effects.

  With reference to FIG. 4, each state when the connector 301 (plug) is inserted into the optical connector (receptacle) 101 and fitting is performed will be described. FIG. 4A shows a state in which insertion of the main body 311 of the optical connector 301 into the opening 112 of the optical connector 101 is started by a user operation. FIG. 4B shows a state in which the insertion of the main body 311 of the optical connector 301 into the opening 112 of the optical connector 101 further proceeds and the optical unit 101a of the optical connector 101 starts to contact the optical unit 301a of the optical connector 301. Is shown. In this state, the electrode 101b of the optical connector 101 is not yet in contact with the electrode 301b of the optical connector 301.

  FIG. 4C shows that the insertion of the main body 311 of the optical connector 301 into the opening 112 of the optical connector 101 further proceeds against the biasing force of the spring member 113, and the optical connector 301 into the opening 112 of the optical connector 101. The fitting state in which the insertion of the main body 311 is completed is shown. In this state, the electrode 101b of the optical connector 101 is in contact with the electrode 301b of the optical connector 301. In this state, the lock member 114 is inserted into the lock hole 313, and this fitting state is maintained against the urging force of the spring member 113.

  Further, with reference to FIG. 4, each state when the connector (plug) 301 is removed from the optical connector (receptacle) 101 and the fitting is released will be described. The operation in this case is the reverse of the case where the connector 301 (plug) is inserted into the optical connector (receptacle) 101 and the fitting is performed.

  The lock is released when the user operates the connector 301 (plug) from the opening 112 of the optical connector (receptacle) 101 in the fitting state shown in FIG. When the lock is released, the optical unit 101a of the optical connector 101 is moved by the biasing force of the spring member, and is moved to the state shown in FIG. In this state, the optical unit 101a of the optical connector 101 is in contact with the optical unit 301a of the optical connector 301, but the electrode 101b of the optical connector 101 is already separated from the electrode 301b of the optical connector 301.

  FIG. 4A shows a state in which the user has further operated from this state in the direction of removing the connector 301 from the optical connector 101. In this state, the electrode 101b of the optical connector 101 is already separated from the electrode 301b of the optical connector 301.

  In the configuration example shown in FIG. 2, when the first electronic device 100 is a transmission-side device and the second electronic device 200 is a reception-side device, an optical connector 301 (plug) is connected to the optical connector (receptacle) 101. The operation of inserting and starting optical data transmission will be described with reference to the flowchart of FIG. In this case, it is assumed that the optical connector 201 of the second electronic device 200 and the optical connector 302 of the optical cable 300 are already in a fitted state.

  In a state where the main body 311 of the optical connector 301 is not inserted into the opening 112 of the optical connector 101, there is no contact between the electrode 101b of the optical connector 101 and the electrode 301b of the optical connector 301, and the optical output from the transmission / reception unit 102 Is in an OFF state or a power-down state (initial state) (step ST1). In this state, the power of the optical signal supplied from the transmission / reception unit 102 to the optical unit 101a of the optical connector 101 is at the second power (a sufficiently low level of safety ensured so as not to cause health damage to the user). .

  From this state, insertion of the main body 311 of the optical connector 301 into the opening 112 of the optical connector 101 is started by a user operation (see FIG. 4A), and when the insertion is further advanced, the optical unit 101a of the optical connector 101 is started. And the optical part 301a of the optical connector 301 start to contact (see FIG. 4B), that is, start the optical coupling (step ST2). And insertion is further advanced from this state (step ST3). Ultimately, the optical connector 301 is fitted to the optical connector 101 (see FIG. 4C).

  The optical output control unit 104 determines whether or not a connection is detected based on the output of the connection detection unit 103, that is, whether or not there is a contact between the electrode 101b of the optical connector 101 and the electrode 301b of the optical connector 301. Judgment is made (step ST4). When determining that the connection is detected, the optical output control unit 104 turns on the optical output from the transmission / reception unit 102 or sets the power output to the power-up state (step ST5). In this state, the power of the optical signal supplied from the transmission / reception unit 102 to the optical unit 101a of the optical connector 101 becomes the first power (power capable of performing high-quality optical data transmission).

  An optical signal with the first power is supplied from the transmission / reception unit 102 to the optical unit 101a of the optical connector 101, and optical data transmission is started (step ST6). In this case, the optical signal supplied from the transmission / reception unit 102 to the optical unit 101a of the optical connector 101 passes through the optical unit 301a of the optical connector 301 of the optical cable 300, the optical transmission path 303, and the optical unit 302a of the optical connector 302. 2 is supplied to the optical unit 201a of the optical connector 201 of the second electronic device 200. The optical signal supplied to the optical unit 201 a is further supplied to the transmission / reception unit 202.

  Next, when the first electronic device 100 is a transmission-side device and the second electronic device 200 is a reception-side device, an optical connector (plug) 301 is fitted to the optical connector (receptacle) 101 (In FIG. 4C, the operation in which the optical data transmission is stopped as described above is performed by removing the connector 301 from the optical connector 101 and stopping the optical data transmission. This will be described with reference to the flowchart of FIG.

  In a state where the optical connector 301 is fitted to the optical connector 101, the electrode 101b of the optical connector 101 is in contact with the electrode 301b of the optical connector 301, and the optical output from the transmission / reception unit 102 is ON (ON) or power It is in a power-up state (initial state) (step ST11). In this state, the power of the optical signal supplied from the transmission / reception unit 102 to the optical unit 101a of the optical connector 101 is the first power (power capable of performing high-quality optical data transmission).

  From this state, removal of the main body 311 of the optical connector 301 from the opening 112 of the optical connector 101 is started by a user operation (step ST12). The optical output control unit 104 determines whether or not a connection is detected based on the output of the connection detection unit 103, that is, whether or not there is a contact between the electrode 101b of the optical connector 101 and the electrode 301b of the optical connector 301. Judgment is made (step ST13).

  When determining that the connection is not detected, the optical output control unit 104 sets the optical output from the transmission / reception unit 102 to an off (OFF) or power-down state (step ST14). In this state, the power of the optical signal supplied from the transmission / reception unit 102 to the optical unit 101a of the optical connector 101 is the second power (a sufficiently low level of safety that ensures safety so as not to cause health damage to the user). . In the state in which the electrode 101b of the optical connector 101 and the electrode 301b of the optical connector 301 start to be separated (the same as the state in which the contact at the time of insertion starts) (see FIG. 4B), the optical connector 101 is already in the state. The electrode 101b and the electrode 301b of the optical connector 301 are separated, and it is determined that the connection is not detected.

  After the optical output from the transmission / reception unit 102 is turned off or powered down, the optical data transmission is stopped (step ST15). Then, the removal is further advanced from this state, and the optical unit 101a of the optical connector 101 and the optical unit 301a of the optical connector 301 are separated (see FIG. 4A) (step ST16). Finally, the optical connector 301 is completely removed from the optical connector 101.
