The electrode 38 and the electrode 39 are electrically connected via the control plug terminal 13 so that a current flows.

(Connector device connection method)
Next, a method for connecting the male connector 10 and the female connector 20 in the present embodiment will be described with reference to FIGS. 4 to 8 are explanatory views of a method for connecting the male connector 10 and the female connector 20 and show a schematic configuration viewed from the front. 9 to 11 are explanatory views of a method for connecting the male connector 10 and the female connector 20 and show a schematic configuration viewed from the side.

  First, FIG. 4 and FIG. 9 show a state before the male connector 10 and the female connector 20 are connected. In this state, the power plug terminal 11 and the power jack terminal 21 are not connected. Similarly, the power plug terminal 12 and the power jack terminal 22 are not connected, and the grounding plug terminal 14 and the grounding jack terminal 24 are not connected. Further, the slide switch 16 is in a state before being moved in the insertion direction (downward), and the control plug terminal 13 is in a contracted state.

  The female connector 20 is provided with a locking claw 25 for engaging and disengaging the stepped portion 19 of the control plug terminal 13. The locking claw 25 has an inclined surface 26 that is inclined with respect to the insertion direction of the control plug terminal 13 and a vertical surface 27 that is perpendicular to the insertion direction.

  Next, FIGS. 5 and 10 show a state in which the male connector 10 is inserted into the female connector 20. In this state, the power plug terminal 11 of the male connector 10 and the power jack terminal 21 of the female connector 20 are fitted. Similarly, the power plug terminal 12 and the power jack terminal 22 are also fitted, and the ground plug terminal 14 and the ground jack terminal 24 are also fitted. In this state, the slide switch 16 remains in a state before being moved in the inserting direction (downward), and the control plug terminal 13 remains in a contracted state. Therefore, the two electrodes 38 and 39 of the control jack terminal 23 are not electrically connected.

  Next, FIG. 6 shows an intermediate state when the control plug terminal 13 is shifted from the contracted state to the extended state when the male connector 10 is inserted into the female connector 20.

  Specifically, by moving the slide switch 16 in the insertion direction (downward), the control plug terminal 13 extends, and the step portion 19 of the control plug terminal 13 contacts the locking claw 25 of the female connector 20. Touch. Then, in the drawing, the stepped portion 19 is pushed to the left by the inclined surface 26 of the locking claw 25, and the control plug terminal 13 is bent to the left.

  Next, FIGS. 7 and 11 show a state in which the control plug terminal 13 is extended in a state where the male connector 10 is inserted into the female connector 20.

  In this state, the two electrodes 38 and 39 of the control jack terminal 23 are electrically connected via the control plug terminal 13. As a result, power is supplied from the relay power source 60 shown in FIG. 1, current flows through the coils 33 and 35 of the relays 31 and 32, the relay contacts 34 and 36 are connected, and the high voltage is supplied via the power jack terminals 21 and 22. Power is supplied from the power supply 50.

  In this state, the control plug terminal 13 is restored, and the stepped portion 19 is locked by the vertical surface 27 of the locking claw 25. Thereby, the control plug terminal 13 can be unintentionally pulled out.

  Thus, according to the present embodiment, when power is supplied from the high-voltage power supply 50, the control plug terminal 13 can be unintentionally pulled out, and safety can be improved.

  Next, FIG. 8 shows a state where the return button 18 is pressed in the state shown in FIG. In this state, the control plug terminal 13 is pushed to the left side by the return button 18 and moves leftward in the drawing, and the stepped portion 19 is detached from the locking claw 25. Thereby, the connection between the male connector 10 and the female connector 20 can be released.

  As described above, in the connector device according to the present embodiment, the power plug terminals 11 and 12 of the male connector 10 are fitted to the power jack terminals 21 and 22 of the female connector 20 and the control plug terminal 13 is connected.

Power is supplied to the information device 40 from the ten plug terminals 11 and 12.

  Thus, the male connector 10 is not connected to the female connector 20 so that power is supplied from the power jack terminals 21 and 22 only when the control plug terminal 13 is extended. This is to prevent a high voltage of 400 VDC from being applied to the power jack terminals 21 and 22 in the state. That is, when a high voltage of 400 VDC is applied to the power jack terminals 21 and 22 of the female connector 20 in a state where the male connector 10 is not joined to the female connector 20, a person is applied to the power jack terminals 21 and 22. In order to prevent such a situation, the human body may be in danger when inadvertently touching or when a person comes in contact with the power jack terminals 21 and 22 through a driver, a metal piece, or a cut lead wire. It is.

(Power supply system)
Next, a configuration of a power supply system using the connector device in the present embodiment will be described.

  FIG. 12 shows a configuration of a power supply system using the connector device according to the present embodiment.

  In this power supply system, AC100V or AC200V power supplied from a commercial power supply 70 is input to the high-voltage power supply 50, and the AC / DC converter 51 in the high-voltage power supply 50 converts AC100V or AC200V to DC400V. Since direct-current power can be stored by a battery or the like, by providing a battery 52 for backup, it is possible to easily cope with a power outage or the like. The female connector 20 in the present embodiment is connected to the high voltage power supply 50 via a power cable, and 400 VDC power from the high voltage power supply 50 is supplied from the female connector 20.

  On the other hand, the male connector 10 in the present embodiment is connected to an information device 40 such as a server via a power cable 15, and the female connector 20 and the male connector 10 are electrically connected to each other from the high voltage power supply 50.

  Also, in the information device 40 such as a server, a DC / DC converter 41 that converts 400 VDC into a low voltage DC output capable of operating electronic components such as the CPU 42 is provided.

  In such a power supply system, conversion from AC to DC from the commercial power source 70 is only one time, so there is little power loss. With 400 VDC, which is a high-voltage direct current, the thickness of the conductors and the like is a concern. Since it is not necessary and it is direct current, it can be stored in the battery 52, and even when the supply of the commercial power supply 70 is stopped due to a power failure or the like, there are advantages such as easy handling.

  Next, a PDU (power distribution unit) using the connector device according to the present embodiment will be described with reference to FIG.

  400 VDC supplied from the high-voltage power supply 50 shown in FIG. 12 is temporarily input to the distribution board 70, and power is distributed to each PDU (power distribution unit) 30. Each PDU 30 is provided with a plurality of female connectors 20 in the present embodiment, and 400 VDC power can be supplied via each female connector 20. On the other hand, a plurality of information devices 40 such as servers are accommodated in the server rack 45, and a male connector 10 for receiving power supply is connected to each information device 40 such as a server via a power cable 15. ing. The male connector 10 is configured to be supplied with power of 400 VDC by being electrically connected to the female connector 20 provided in the PDU 30.

[Second Embodiment]
The second embodiment relates to a male connector according to the present invention. Specifically, the control plug terminal is contracted by the restoring force of the torsion coil spring.

  FIG. 14 shows the configuration of the male connector of the present embodiment. 14A is a perspective view of the male connector 110 with the control plug terminal 113 contracted, and FIG. 14B is a perspective view of the male connector 110 with the control plug terminal 113 extended. FIG. FIG. 14C is a perspective view of the male connector 110 in a state where the control plug terminal 113 is extended and the return button 118 is pressed.

  The male connector 110 in this embodiment includes two power plug terminals 111 and 112 for receiving power supply, a control plug terminal 113, a grounding plug terminal 114 for grounding, a slide switch 116, and a return button. 118. The return button 118 protrudes from the opening of the slide switch 116 in the direction perpendicular to the insertion direction, and is urged in the protruding direction by an urging means (not shown).

  The slide plug 116 is slid in the insertion direction of the control plug terminal 113 from the state shown in FIG. 14A to the state shown in FIG. 14B, so that the control plug terminal 113 extends. is there. In addition, when the return button 118 is pressed from the state shown in FIG. 14B to the state shown in FIG. 14C, the control plug terminal 113 moves perpendicularly to the insertion direction. .

  Next, a case where the control plug terminal 113 is extended in the male connector 110 according to the present embodiment will be described with reference to FIGS. 15 and 16. By extending the control plug terminal 113, the two control electrodes provided on the control jack terminal in the female connector (not shown) are changed from the insulated state to the conductive state.

  FIG. 15A is an internal structure diagram in a state in which the control plug terminal 113 is contracted, and FIG. 15B is an internal perspective view in a state in which the control plug terminal 113 is contracted. FIG. 15C is an internal structure diagram in a state where the control plug terminal 113 is extended and before the return button 118 is pressed, and FIG. It is an internal perspective view in a state in which the state is extended and before the return button 118 is pressed. FIG. 15E is an internal structure diagram in a state where the control plug terminal 113 is extended and the return button 118 is pressed, and FIG. It is an internal perspective view in the state when it is in the extended state and the return button 118 is pressed. FIG. 16 is a partially enlarged view of FIG.

  As shown in FIGS. 15A and 15B, the slide switch 116 has a configuration in which the control plug terminal 113 extends through a return button 118. A coil spring 123 is connected to the control plug terminal 113, and the coil spring 123 is slightly contracted. The return button 118 is biased in the protruding direction via the control plug terminal 113 by the restoring force of the coil spring 123. In the present embodiment, the control plug terminal 113 and the return button 118 are integrally formed.

  In addition, a torsion coil spring 120 is provided inside the male connector 110. The torsion coil spring 120 is supported in a state where one end 120a is rotatable on the housing of the male connector 110, and the other end is a cam shaft. 121 is connected in a rotatable state. The cam shaft 121 is configured to be movable in the cam groove 122 and is inserted into the cylindrical portion 117 of the slide switch 116.

  In a state where the control plug terminal 113 is contracted, the slide switch 116 is located on the left side in the drawing, the cam shaft 121 is located on the leftmost side in the cam groove 122, and the left side of the cylindrical portion 117 is located. It is in contact with the inner wall surface. At this time, the torsion coil spring 120 is in a slightly closed (flexed) state compared to the natural state.

  Thereafter, when the slide switch 116 is moved in the insertion direction (right direction) with respect to the insertion direction, the control plug terminal 113 is pushed to the right side by the return button 118 and moved to the right side. The cam shaft 121 is pushed to the right and moves in the cam groove 122 in the right direction. Along with this, the torsion coil spring 120 is further closed (flexed). The restoring force of the torsion coil spring 120 becomes strongest immediately before the cam shaft 121 moves to the rightmost side in the cam groove 122. When the camshaft 121 moves to the rightmost side in the cam groove 122, the torsion coil spring 120 is restored (opened), and the state shown in FIGS. 15 (c) and 15 (d) is obtained.

  In this state, in the drawing, the slide switch 116 has moved to the right side, and the control plug terminal 113 has also moved to the right side. The cam shaft 121 moves to the rightmost side in the cam groove 122 and is in contact with the inner wall surface on the right side of the cylindrical portion 117. At this time, the torsion coil spring 120 is in a state of being slightly closed (bent) than the natural state.

  In this way, the control plug terminal 113 can be extended in the insertion direction. This is performed against the restoring force of the torsion coil spring 120.

  Next, a case where the control plug terminal 113 is contracted in the male connector 110 according to the present embodiment will be described with reference to FIGS. 15 and 16. When the control plug terminal 113 is contracted, the two control electrodes provided on the control jack terminal in the female connector (not shown) are changed from the conductive state to the insulated state.

  As shown in FIGS. 15C and 15D, when the control plug terminal 113 is extended, the slide switch 116 is located on the right side and the control plug terminal 113 is also located on the right side in the drawing. ing. The cam shaft 121 is located on the rightmost side in the cam groove 122 and is in contact with the inner wall surface on the right side of the cylindrical portion 117. At this time, the torsion coil spring 120 is in a slightly closed (flexed) state compared to the natural state.

  Thereafter, when the return button 118 is pressed, the state shown in FIGS. 15E and 15F is obtained.

  In this state, in the drawing, the control plug terminal 113 is pushed upward by the return button 118 and moves upward in an extended state. At this time, the cam shaft 121 is pushed upward by the side surface of the control plug terminal 113 and moves upward in the cam groove 122. In this state, the torsion coil spring 120 is more closed (flexed) than the states shown in FIGS. 15C and 15D, and the restoring force of the torsion coil spring 120 is stronger.

  Thereafter, due to the restoring force that the torsion coil spring 120 opens, the cam shaft 121 moves to the left in the cam groove 122 in the drawing, and the state shown in FIGS. 15A and 15B is obtained.

  That is, due to the restoring force that the torsion coil spring 120 opens, the cam shaft 121 moves to the left in the cam groove 122 in the drawing, and thereby the left inner wall surface of the cylindrical portion 117 of the slide switch 116 is pushed. The control plug terminal 113 is contracted in the insertion direction via the return button 118.

  In this state, in the drawing, the slide switch 116 has moved to the left side, and the control plug terminal 113 has also moved to the left side. The cam shaft 121 moves to the leftmost side in the cam groove 122 and is in contact with the inner wall surface on the left side of the cylindrical portion 117. At this time, the torsion coil spring 120 is in a state of being opened more than the state shown in FIGS.

  In this way, the control plug terminal 113 can be contracted in the insertion direction. This is performed in a short time because the control plug terminal 113 is contracted in the insertion direction by the restoring force of the torsion coil spring 120, that is, the force by which the torsion coil spring 120 opens.

  By the way, in the case of such a configuration that does not have the torsion coil spring 120, the control plug terminal 113 is contracted in the insertion direction only by the force of a human finger.

  In such a case, the control plug terminal 113 is contracted at a low speed, and an arc or chattering occurs at a contact of a female connector (not shown) connected by the control plug terminal 113. . Such arcing or chattering may damage the contact of the female connector or damage the device connected to the male connector 110.

  In the male connector 110 in the present embodiment, since the control plug terminal 113 can be shortened in a short time, the occurrence of such arcing and chattering can be prevented, the contact of the female connector can be damaged, It becomes possible to prevent the device connected to the male connector 110 from being destroyed.

  In the present embodiment, the control plug terminal 113 is expanded and contracted by using the restoring force that works in the direction in which the torsion coil spring 120 is closed (flexed) from the closed (flexed) state. By changing the structure of the cam groove 122 and the like, the control plug terminal 113 can be expanded and contracted in the same manner by using a restoring force for closing the torsion coil spring 120 from the open (flexed) state.
