Description

  The present invention relates to an electronic device.

  In recent years, the number of users of portable information processing terminals such as tablet terminals and smartphones has increased rapidly due to improved performance in addition to portability. Furthermore, in order to further improve the convenience of such an information processing terminal, there is an electronic device for function expansion that extends the function by connecting the information processing terminal.

  For example, as such an electronic device for function expansion, there is a keyboard dock that enables comfortable keyboard operation by connecting a portable computer to an information processing terminal that does not have a keyboard. . Such an electronic device such as a keyboard dock transmits an electrical signal to the information processing terminal.

  Furthermore, electronic devices for function expansion include devices that not only transmit electrical signals to information processing terminals but also supply power.

  When transmitting and receiving electricity such as electric signals and power between the electronic device for function expansion and the information processing terminal, it is preferable that the connectors of the electronic device and the information processing terminal are securely connected.

  Therefore, in order to maintain the connection state with the information processing terminal, a lock structure that prevents the connectors from being separated from the inserted state is often used in the electronic device for function expansion.

  Further, as a connector connection technique, there has been proposed a conventional technique for reducing the load on a connector for connecting printed circuit boards by supporting the printed circuit boards with support columns having a pressing force in the inner direction. In addition, there has been proposed a conventional technique for improving electrical connectivity by bringing a contact terminal into contact with an electrode with a pressing force of a spring when the electrode is inserted.

  However, even if the lock structure is used, it is difficult to assemble both the information processing terminal and the electronic device for function expansion with high accuracy without variation of parts. For this reason, the clearance for fitting may be increased even in the locked state, the gap between the connectors may be opened, and the contact pressure may not be sufficiently ensured. In addition, there may be a case where the information processing terminal is inserted obliquely and the connection on one side of the connector becomes unstable.

  Further, even when the conventional technique for holding the substrate by the support column pressing inward is used, the connection of the connector may be unstable, and transmission / reception of electricity may be continued in an unstable connection state. In addition, even if the conventional technique in which the contact terminal is brought into contact with the electrode by the pressing force of the spring is used, there is still a possibility that the connection of the connector becomes unstable, and the transmission / reception of electricity may be continued with the connection being unstable. There is.

  The disclosed technology has been made in view of the above, and an object thereof is to provide an electronic device that suppresses transmission and reception of electricity in an unstable connection state.

In one aspect, the electronic device disclosed in the present application includes an electrode that contacts the connection terminal when the connection terminal of the electronic device is pressed to supply electricity to the electronic device. The housing has a fixed surface at a position facing the bottom surface of the connector opposite to the side on which the other electronic device is pressed, and holds the connector movably in the pressing direction from the other electronic device. . The elastic member is a sponge disposed between the fixed surface so as to cover the entire bottom surface of the connector. The control unit permits power supply to the electronic device when a pressing force on the connector to the electronic device is a predetermined value or more, and supplies power to the electronic device when the pressing force is a predetermined value or less. Stop.

  According to one aspect of the electronic device disclosed in the present application, there is an effect that transmission / reception of electricity in an unstable connection state can be suppressed.

  Hereinafter, embodiments of an electronic device disclosed in the present application will be described in detail with reference to the drawings. The electronic devices disclosed in the present application are not limited by the following embodiments. In particular, in the following embodiments, a keyboard dock is described as an example of an electronic device. However, the present invention is not limited to this, and the same configuration can be used as long as the electronic device expands the function of the information processing terminal.

  FIG. 1 is a perspective view of a state in which a tablet terminal is connected to a keyboard dock according to an embodiment. FIG. 2 is a rear view of the tablet dock connected to the keyboard dock according to the embodiment. FIG. 2 is a view of the keyboard dock and the tablet terminal in the state of FIG. 1 as viewed from the direction of the arrow D1.

  As shown in FIG. 1, the keyboard dock 1 has a docking unit 10. In this embodiment, the docking unit 10 has a hinge mechanism and is disposed so as to be rotatable. The docking unit 10 has a connector described later. The connector of the docking unit 10 is connected to the connector of the tablet terminal 2. By connecting the docking unit 10 and the tablet terminal 2, the tablet terminal 2 is connected to the keyboard dock 1 and can receive an electrical signal input from the keyboard. In addition, the tablet terminal 2 can receive power supplied from the keyboard dock 1.

  The tablet terminal 2 has a connector shown in FIG. FIG. 3 is a plan view of the connector of the tablet terminal. As shown in FIG. 3, the connector 21 of the tablet terminal 2 has an electrode 22 having a flat surface in the connection direction. This tablet terminal 2 corresponds to an example of “another electronic device”.

  Next, details of the docking unit 10 will be described. FIG. 4 is an exploded perspective view of the keyboard dock. FIG. 4 shows a state in which the tablet terminal 2 is detached from the keyboard dock 1 from the state of FIG. 1, and the front cover 11 of the docking unit 10 is removed after the docking unit 10 is removed from the keyboard dock 1. . In FIG. 4, for convenience of illustration, the internal structure of the docking unit 10 is simplified and illustrated. Details of the internal structure of the docking unit 10 are shown in FIG.

  FIG. 5 is a perspective view showing the internal structure of the docking portion. Specifically, FIG. 5 shows a state in which the peripheral portion of the connector 101 of the docking unit 10 with the front cover 11 in FIG. 4 removed is enlarged. FIG. 6 is a front view showing the internal structure of the docking portion. 6 is a diagram of the docking unit 10 in FIG. 5 as viewed from the direction of the arrow D2. However, in FIG. 5 and FIG. 6, the periphery of the connector portion is shown enlarged for convenience of explanation, and both side end portions of the docking portion 10 unnecessary for explanation are omitted.

  As shown in FIGS. 5 and 6, the docking unit 10 includes a connector 101, an electrode pin 102, a guide pin 103, a lock mechanism 104, an elastic member 105, a switch 106, a switch 107, and a fixing plate 108 in a housing 100. , A support 109 and a substrate 110.

  The housing 100 is a member that forms the outer wall of the docking unit 10. For example, the housing 100 holds a fixed position with respect to insertion and removal of the tablet terminal 2 in a state where the keyboard dock 1 is placed on a fixed surface.

  The connector 101 is a contact pressure contact type connector. The connector 101 has electrode pins 102 on the side connected to the connector 21 of the tablet terminal 2. That is, the tablet terminal 2 is inserted in the X direction of FIG. The connector 101 supports the electrode pin 102 from the opposite direction of the X direction by a spring. Hereinafter, the reverse direction of the X direction, that is, the reverse direction of the direction in which the tablet terminal 2 is inserted is referred to as “reverse X direction”.

  Further, the connector 101 has guide pins 103. When the tablet terminal 2 is inserted into the docking unit 10, the hole at the end of the connector 21 is fitted with the guide pin 103. Accordingly, the tablet terminal 2 is inserted into the docking unit 10 without the position of the connector 21 with respect to the connector 101 being shifted.

  When the connector 21 of the tablet terminal 2 is inserted while being guided by the guide pin 103, the electrode pin 102 is pressed by the surface of the electrode 22 of the connector 21. Then, the electrode pin 102 moves in the X direction while squeezing a spring disposed in the connector 101 in the reverse X direction, and enters the connector 101. At this time, the electrode pin 102 receives a force in the reverse X direction from a spring disposed inside the connector 101 and is pressed against the surface of the electrode 22 by the received force. Thereby, the electrode pin 102 will maintain a contact with the electrode 22, if the tablet terminal 2 is the state pressed to the X direction with appropriate force.

  The electrode pin 102 transmits the power supplied from the power supply of the keyboard dock 1 to the tablet terminal 2 via the electrode 22 in contact therewith. In addition, the electrode pin 102 transmits an electrical signal input using the keyboard of the keyboard dock 1 to the tablet terminal 2 via the electrode 22 that is in contact with the electrode pin 102. This electrode pin 102 is an example of an “electrode”.

  Further, the connector 101 is placed and fixed on the surface of the substrate 110 on the side where the tablet terminal 2 is inserted. When the electrode pin 102 is pressed by fitting with the connector 21, the entire connector 101 is also moved in the insertion direction of the tablet terminal 2, that is, the X direction by the pressing force of the tablet terminal 2 received by the electrode pin 102. And the connector 101 presses the board | substrate 110 by moving to a X direction with the pressing force from the tablet terminal 2. FIG. The pressing force of the substrate 110 by the connector 101 matches the pressing force that the electrode pin 102 receives from the electrode 22 in a state where the tablet terminal 2 is inserted.

  As described above, the keyboard dock 1 transmits, for example, power and electric signals to the tablet terminal 2. Hereinafter, power transmission, that is, power supply from the keyboard dock 1 to the tablet terminal 2 will be described as an example.

  The lock mechanism 104 is disposed in both the Y directions with the connector 101 interposed therebetween. The lock mechanism 104 is fitted with a lock mechanism (not shown) of the tablet terminal 2 inserted into the docking unit 10 to prevent the tablet terminal 2 from moving in the insertion direction, that is, the reverse X direction. Accordingly, the lock mechanism 104 prevents the tablet terminal 2 in a state where the connector 21 is inserted into the connector 101 from being detached from the connector 101 due to a spring force that pushes the electrode pin 102 in the reverse X direction.

  The board | substrate 110 has the connector 101 mounted and fixed on the surface by which the tablet terminal 2 is inserted, ie, the surface which goes to a reverse X direction. And the board | substrate 110 is hold | maintained by the support | pillar 109 so that it can move in the press direction by insertion of the tablet terminal 2 from the both ends of a Y direction, ie, a X direction, and the reverse direction in the predetermined range. For example, the movement limit in the X direction of the substrate 110 is set between the position in the X direction where the switch 106 and the switch 107 are turned on and the position in the X direction where each switch is pressed. Further, for example, the movement limit in the reverse X direction of the substrate 110 is a position in the X direction where the switch 106 and the switch 107 are turned off, and is a position advanced in the reverse X direction from the position where the elastic member 105 is restored. Is set.

  The board 110 receives from the connector 101 the pressing force that the electrode pins 102 receive from the electrode 22 in a state where the tablet terminal 2 is inserted. Since the substrate 110 is movable in the X direction, the substrate 110 is moved in the X direction by the pressing force received from the connector 101. The substrate 110 crushes an elastic member 105 described later by this movement.

  Further, when the tablet terminal 2 is pulled out from the docking unit 10, the substrate 110 receives a pressing force from an elastic member 105 described later in a direction in which the docking unit 10 is pulled out. The substrate 110 moves in the reverse X direction by the pressing force received from the elastic member 105. By this movement, the board 110 moves the connector 101 in the direction opposite to the X direction.

  The column 109 is a column extending in the X direction. The support column 109 is fixed to the housing 100. That is, the position of the support 109 does not change even if the connector 101 is moved in the X direction and the reverse X direction by inserting and removing the tablet terminal 2. The column 109 holds the substrate 110 so as to be movable within a predetermined range in the X direction and the reverse X direction.

  Further, the elastic member 105, the switches 106 and 107, and the fixing plate 108 will be described with reference to FIG. FIG. 7 is an enlarged view of the inside of the docking unit. FIG. 7 shows an enlarged view of the elastic member 105, the switches 106 and 107, and the fixing plate 108 in FIG. However, in FIG. 7, in order to make the drawing easier to see, members unnecessary for the description of the cable and the like are omitted.

  The fixed plate 108 is fixed to the housing 100. That is, the position of the fixing plate 108 does not change even if the connector 101 is moved in the X direction and the reverse X direction by inserting and removing the tablet terminal 2. Since the fixed plate 108 and the column 109 are fixed to the housing 100, it can be considered as a part of the housing 100. A surface of the fixing plate 108 facing the connector 101 is an example of a “fixing surface”.

  The elastic member 105 is made of, for example, a sponge. The elastic member 105 is disposed between the substrate 110 and the fixing member 108. Further, the elastic member 105 is fixed to the fixing plate 108.

  The elastic member 105 receives a pressing force from the substrate 110 in a state where the tablet terminal 2 is inserted. The pressing force that the elastic member 105 receives from the substrate 110 when the tablet terminal 2 is inserted matches the pressing force that the connector 101 receives from the tablet terminal 2. The elastic member 105 is crushed by receiving a pressing force from the substrate 110. And the elastic member 105 presses the board | substrate 110 with a restoring force in the crushed state.

  Further, when the tablet terminal 2 is pulled out, the elastic member 105 presses the substrate 110 with a restoring force and moves the substrate 110 in the reverse X direction.

  Switches 106 and 107 are stroke switches. The switches 106 and 107 are switches that turn on or off the power supply to the tablet terminal 2. FIG. 8 is a diagram of a switch operation table. The switches 106 and 107 perform power feeding control as shown in the operation table of FIG.

  Specifically, when both the switches 106 and 107 are turned on, power is supplied to the tablet terminal 2 via the electrode pins 102. In addition, when one or both of the switches 106 and 107 are OFF, power supply to the tablet terminal 2 is stopped.

  The switches 106 and 107 are fixed to the surface opposite to the mounting surface of the connector 101 of the connector substrate 110, that is, the surface opposite to the insertion side of the tablet terminal 2 with the stroke pin directed in the X direction.

  Here, in this embodiment, the switches 106 and 107 are fixed on the substrate 110 with the stroke pins facing in the X direction, but may be fixed on the fixing plate 108 in the reverse X direction, for example. Further, the directions of the switches 106 and 107 may be reversed.

  Further, the switch 106 is disposed in the vicinity of the end of the connector 101 in the reverse direction of the Y direction (hereinafter referred to as “reverse Y direction”). The switch 107 is disposed near the end of the connector 101 in the Y direction.

  When the end of the connector 101 in the reverse Y direction moves in the X direction, the switch 106 receives a pressing force from the substrate 110 and the stroke pin is pressed by the fixed plate 108. Then, the switch 106 is turned on when the stroke pin is pressed beyond the position where the stroke pin is turned on.

  Further, when the board 110 moves in the reverse X direction by moving the end portion side of the connector 101 in the reverse Y direction, the force with which the stroke pin of the switch 106 is pressed from the fixed plate 108 is weakened. When the substrate 110 moves in the reverse X direction beyond the position where the stroke pin is turned off, the switch 106 is turned off.

  When the end of the connector 101 in the Y direction moves in the X direction, the switch 107 receives a pressing force from the substrate 110 and the stroke pin is pressed by the fixed plate 108. Then, the switch 107 is turned on when the stroke pin is pressed beyond the position where it is turned on.

  Moreover, when the board | substrate 110 moves to a reverse X direction because the edge part side of the Y direction of the connector 101 moves to a reverse X direction, the force by which the stroke pin of the switch 107 is pushed down from the fixed board 108 will become weak. When the substrate 110 moves in the reverse X direction beyond the position where the stroke pin is turned off, the switch 107 is turned off. The switches 106 and 107 correspond to an example of a “control unit”.

  Furthermore, with reference to FIG. 9, the pressing force to the switches 106 and 107 when the tablet terminal 2 is inserted and the arrangement method of the switches 106 and 107 will be described. FIG. 9 is a diagram illustrating a pressing force and a moving state when the tablet terminal is inserted.

  When the tablet terminal 2 is inserted and the connector 21 is engaged with the connector 101 as shown in FIG. 8, the electrode pin 102 receives the compressive load P1 in the X direction. In response to this pressing force P1, the connector 101 presses the substrate 110 in the X direction. Then, the substrate 110 presses the elastic member 105 in the X direction. Thereby, the elastic member 105 receives the compression load P2. Here, the compression load P1 of the electrode pin 102 = the compression load P2 of the elastic member 105.

  When the elastic member 105 is pressed with the compression load P2, the elastic member 105 is compressed by the compression amount S1. The compression amount S1 is a length by which the elastic member 105 is contracted in the X direction. Further, the switch 106 is pushed by the stroke of the switch operation amount S2 by the movement of the substrate 110. Here, the switch operation amount 2 is the length by which the stroke pin is pushed. The compression amount S1 of the elastic member 105 is equal to the switch operation amount S2.

  Here, since the elastic member 105 has a constant spring constant, the compression amount with respect to the compression load P2 can be calculated. That is, the compression amount S1 is uniquely obtained for the compression load P2.

  Further, if the compressive load P1 on the electrode pin 102 is sufficiently large, that is, if the contact pressure between the connectors falls within the specification range, the contact between the electrode pin 102 and the electrode 22 is reliably maintained, and the connector 101 and the connector 21 are connected. Connected securely.

  Therefore, the detection position of the switch 106 is set so that the contact pressure between the connectors falls within the specification range. For example, as for the compression load P1 of the electrode pin 102 that securely connects the connectors, the contact pressure between the connectors is obtained using a specification range. Furthermore, the compression amount S1 of the elastic member 105 when the connectors are reliably connected is obtained from the obtained compression load P1. Then, the switch 106 is arranged so that the switch 106 is turned off when the compression amount S1 of the obtained elastic member 105 is less than S1. That is, the switch 106 is arranged so that the switch 106 is turned off when the switch operation amount S2 is the compression amount limit value. The switch 107 is similarly arranged.

  Furthermore, the states of the switches 106 and 107 according to the insertion state of the tablet terminal 2 will be described together with reference to FIGS. FIG. 10A is a diagram illustrating a state of a switch before insertion of the tablet terminal. FIG. 10B is a diagram illustrating a state of the switch when the tablet terminal is appropriately inserted. FIG. 10C is a diagram illustrating a state of the switch when the tablet terminal is inclined. 10A to 10C show the state of the end of the tablet terminal 2, and the connector 21 of the tablet terminal 2 is not shown.

  As illustrated in FIG. 10A, when the tablet terminal 2 is not inserted into the docking unit 10, the connector 101 does not receive a pressing force. For this reason, the elastic member 105 is not crushed, and neither of the switches 106 and 107 presses the stroke pin. Therefore, in this case, both the switches 106 and 107 are turned off. Therefore, in this state, power supply from the keyboard dock 1 to the tablet terminal 2 is not performed. This is the same when the fitting between the connector 101 and the connector 21 of the tablet terminal 2 is weakened and the connection between the connectors becomes incomplete.

  Next, as shown in FIG. 10B, when the tablet terminal 2 is inserted into the docking unit 10, the connector 101 and the connector 21 are fitted, and the connectors are completely connected to each other, the connector 101 is connected to the switches 106 and 107. It receives a pressing force that is more than ON. Thereby, the elastic member 105 is crushed equally at both ends in the Y direction. The stroke pins of the switches 106 and 107 are moved according to the pressing force of the connector 101. As a result, both the switches 106 and 107 are turned on. Therefore, in this case, power is supplied from the keyboard dock 1 to the tablet terminal 2. Here, as shown in FIG. 10B, all the electrode pins 102 of the connector 101 are in contact with the electrodes 22 of the connector 21 under sufficient contact pressure. For this reason, even if power is supplied in this state, the risk of leakage etc. is low.

  Next, as illustrated in FIG. 10C, when the insertion state of the tablet terminal 2 is inclined so that the switch 107 side is separated from the docking unit 10, the pressing force at the end of the connector 101 on the switch 107 side is weakened. In this case, the elastic member 105 is in a state where both ends in the Y direction are crushed unevenly. As a result, the substrate 110 on the switch 107 side moves away from the fixed plate 108, and the switch 107 is turned off. On the other hand, since the substrate 110 on the switch 106 side is not separated from the fixed plate 108, the switch 106 is maintained in the ON state. In this case, since the switch 107 is turned off, power supply from the keyboard dock 1 to the tablet terminal 2 is stopped. Here, as shown in FIG. 10C, the contact pressure between the electrode pin 102 at the end in the Y direction and the electrode 22 of the connector 21 is weakened. When power is supplied in this state, there is a high risk of leakage. Therefore, when the insertion state of the tablet terminal 2 is inclined as described above, it is safe to stop power feeding.

  As described above, when the tablet terminal 2 is inserted, the connector 101 receives a sufficient pressing force, and both the switches 106 and 107 are turned on, power supply to the tablet terminal 2 is started. Further, when the connector 21 of the inserted tablet terminal 2 and the connector 101 are weakly fitted and the connector 101 does not receive a sufficient pressing force, the switches 106 and 107 are turned OFF and the power feeding is stopped. Further, when one end of the connector 101 is lifted because the inserted tablet terminal 2 is tilted or the like, either the switch 106 or 107 is turned OFF and the power supply is stopped.

  Next, control of power supply to the tablet terminal by the keyboard dock according to the present embodiment will be described with reference to FIG. FIG. 11 is a flowchart of control of power supply to the tablet terminal by the keyboard dock according to the embodiment. Here, a case where the control circuit controls power feeding in accordance with the ON and OFF of the switches 106 and 107 will be described.

  The operator inserts the tablet terminal 2 into the docking unit 10 of the keyboard dock 1 (step S1).

  The control circuit determines whether or not the switch 106 is ON (step S2). When the switch 106 is ON (Step S2: Yes), the control circuit determines whether or not the switch 107 is ON (Step S3).

  When the switch 107 is ON (step S3: Yes), the control circuit supplies power to the tablet terminal 2 (step S4).

  On the other hand, when the switch 106 is OFF (step S2: negative) or when the switch 107 is OFF (step S3: negative), the control circuit stops power supply to the tablet terminal 2 (step S5).

  Thereafter, the control circuit determines whether or not the keyboard dock 1 has stopped operating (step S6). For example, the stop of the operation of the keyboard dock 1 occurs when the tablet terminal 2 is removed from the keyboard dock 1 or the like.

  When the keyboard dock 1 does not stop the operation (No at Step S6), the control circuit returns to Step S2.

  On the other hand, when the keyboard dock 1 stops operating (step S6: affirmative), the control circuit ends the control of power supply to the tablet terminal.

  As described above, the keyboard dock according to the present embodiment supplies power when the pressing force related to the connector to which the tablet terminal is connected is strong, and stops supplying power when the pressing force is weak. Thereby, when the pressing force concerning the connector is weak and the connection between the connectors is unstable, the power supply to the tablet terminal is stopped.

  Moreover, although the electric power feeding to the tablet terminal 2 was demonstrated above as an example, if the object supplied to the tablet terminal 2 is electricity, it will not be restricted to the power supply of the tablet terminal 2. FIG. For example, even a device that transmits an electrical signal to the tablet terminal 2 according to input from a keyboard has the same effect.

  Furthermore, although the electronic device for function expansion to a tablet terminal was demonstrated above, if the electronic device for function expansion is the structure which sends electricity with respect to the connected apparatus, it will not be restricted to a tablet terminal, for example, It may be a mobile phone. In the above, a sponge is used as the elastic member. However, the present invention is not limited to this, and for example, a leaf spring or a coil may be used. Further, without using an elastic member other than the substrate, the substrate may be fixed and the elastic member may be formed by using the bending force of the substrate itself.

  In the present embodiment, the case where the stroke switch is used has been mainly described as an example. However, the present invention is not limited to this. But you can. For example, the distance between the substrate and the fixing member may be measured by a distance sensor, and the control of power feeding may be performed using the measurement result as the measurement result of the pressing force. Further, the pressing force applied to the connector may be measured using a pressure sensor, and power feeding may be controlled according to the measured value. In that case, the substrate may be fixed. Alternatively, the substrate may be fixed, the deflection of the substrate may be measured using a deflection sensor, and power feeding may be controlled using the measurement result as the measurement result of the pressing force.

  In addition, in this embodiment, two switches are arranged near both ends of the connector in order to detect when the tablet terminal is inserted obliquely. However, if the diagonal state is not detected, the switch is You may arrange only one. Even with this configuration, an incomplete connection between the connectors can be detected. Two or more switches may be arranged.
