JP 2011-165609 A

  In the vehicle charging connector described in Patent Document 1, the operation member can be operated (pushing operation) even when the locking claw and the operation member are not coupled by the coupling mechanism. Therefore, for example, when the user operates the operating member when the user does not have the electronic key, the vehicle charging connector is locked to the vehicle-side connector by the locking claws, even though the operating member is operated. It will remain as it is. On the other hand, since the user cannot recognize this state, the user may try to remove the vehicle charging connector, and if the user cannot remove the vehicle charging connector, the user may try to pull out the vehicle charging connector with a stronger force. For this reason, there is a possibility that breakage or the like may occur depending on the strength of the locking claw, the coupling mechanism, or the housing that houses them.

  Therefore, the present invention includes a mechanism for restricting the user's operation to release the locking to the vehicle-side connector, and in a state where the locking to the vehicle charging connector cannot be released when this mechanism is operating. An object of the present invention is to provide a vehicular charging connector that allows a user to reliably recognize that there is.

  In order to solve the above-mentioned problems, the present invention provides a housing in which first and second openings are formed, a vehicle-side connector that is fixed to the housing and provided in a vehicle, and is fitted to the vehicle. A connector portion that outputs a charging current, a locking portion that protrudes from the first opening to the outside of the housing and is locked to the vehicle-side connector, and is exposed from the second opening and operated by a user. An operation part, and a lever member that has a connecting part that integrally connects the locking part and the operating part, and the locking of the locking part to the vehicle-side connector is released by operation of the operating part; An operation restricting mechanism that is disposed inside the housing and is switched between an operating state and a non-operating state by an electric current supplied from the outside of the housing, and that restricts the operation of the operation unit in the operating state. To provide a vehicle charging connector was painting.

  The operation restriction mechanism includes an electromagnet to which the current is supplied and a mover that operates by a magnetic field generated by the electromagnet, and the mover restricts the operation of the operation unit by energizing the electromagnet. It may be configured to move to a position.

  The movable element includes a large-diameter portion and a small-diameter portion that are rotatably supported by a support portion provided in the housing and that have different distances from the rotation center to the outer peripheral surface thereof, and the operation restriction mechanism. In the operating state in which the electromagnet is energized, the large diameter portion abuts on the lever member by the operation of the operation portion to regulate the operation, and in the non-operating state in which the electromagnet is not energized, the small diameter portion is It is good to comprise so that the said operation may be permitted facing the said lever member.

  In addition, the mover includes a magnet portion that is rotated by a magnetic field generated by the electromagnet, and a rotating member that rotates with the rotation of the magnet portion and changes a distance from the lever member by the rotation. The operation restricting mechanism restricts the operation when the lever member comes into contact with the rotating member by an operation by the user in an operating state in which the electromagnet is energized, and in an inoperative state in which the electromagnet is not energized, The rotating member may be configured to allow the operation without contacting the lever member.

  The operation restricting mechanism may be configured such that, when the current is supplied when the operation unit of the lever member is operated by the user, the movable element moves to the operation unit when the operation is released. You may comprise so that it may move to the position which controls operation.

  According to the vehicle charging connector according to the present invention, when the mechanism that restricts the user's operation to release the locking to the vehicle-side connector is operating, this locking cannot be released. It is possible to make sure that the person recognizes it.

  The housing 10 has a hollow main body 100 in which the accommodation space 1a is formed. The main body 100 is formed with a first opening 10a and a second opening 10b that allow the accommodation space 1a to communicate with the outside. The housing 10 is made of an insulating resin such as PPS (polyphenylene sulfide) resin, PPA (polyphthalamide) resin, PA (polyamide) resin, PBT (polybutylene terephthalate), or epoxy resin.

  A connector portion 11 having a plurality of terminals to be described later is fixed to the main body portion 100 of the housing 10. Connector portion 11 is fitted to vehicle-side connector 91 provided in the vehicle, and outputs a charging current to the vehicle. A plurality of terminals in the connector portion 11 are connected to each electric wire of the multicore cable 130 inside the housing 10.

  The lever member 2 protrudes from the first opening 10a to the outside of the housing 10 and is exposed from the locking portion 21 locked to the vehicle-side connector 91 (to be caught and restrained in relative movement) and from the second opening 10b. The operation unit 22 is operated by the user, and the connecting unit 23 integrally connects the locking unit 21 and the operation unit 22. The connecting portion 23 is pivotally supported in the housing space 1a of the housing 10 so as to be swingable. More specifically, a columnar support portion 101 provided in the main body portion 100 of the housing 10 is inserted through the through-hole 230 formed in the connecting portion 23, and the support portion 101 is centered within a predetermined angle range. Thus, the lever member 2 can be rotated.

  The vehicle-side connector 91 has a recess 910 that engages with a locking claw 210 formed in the locking portion 21. The lever member 2 swings around the support portion 101 when the user performs an operation of pushing the operation portion 22 toward the inside of the main body portion 100 of the housing 10 (hereinafter, this operation is referred to as “pushing operation”). The locking of the locking portion 21 to the vehicle-side connector 91 (engagement between the locking claw 210 and the recess 910) is released. In FIG. 1, the locked state where the locking portion 21 is locked to the vehicle-side connector 91 is indicated by a solid line, and the contour of the lever member 2 in the unlocked state where the locking is released is indicated by a two-dot chain line. Yes.

  In the housing 10, the elastic member 12 is disposed between the inner surface of the main body 100 and the connecting portion 23 of the lever member 2. The lever member 2 is biased by the elastic member 12 in the direction in which the locking claw 210 engages with the recess 910. In the present embodiment, the elastic member 12 is composed of a coil spring, and the connecting portion 23 is urged by its restoring force.

  The operation restricting mechanism 3 is disposed inside the housing 10 so as not to be exposed to the outside of the housing 10, and is switched between an operating state and a non-operating state by a current supplied from the outside of the housing 10. 22 pushing operation is controlled. In the present embodiment, the operation restriction mechanism 3 includes a mover 30 including a cylindrical tube portion 31 and a fan-shaped magnet 32, and an electromagnet 33 to which an excitation current is supplied from the outside of the housing 10 by an electric wire 330. Configured. The cylindrical portion 31 is made of a metal such as aluminum, and the magnet 32 is made of a ferromagnetic material such as iron or ferrite.

  A cylindrical shaft portion 102 provided in the main body portion 100 of the housing 10 is inserted into the cylindrical portion 31. The mover 30 is rotatably supported by the shaft portion 102, and the cylindrical portion 31 and the magnet 32 rotate integrally around the shaft portion 102.

  The main body 100 of the housing 10 is provided with a pair of holding members 103 that hold the electromagnet 33 and a pair of guide members 104 that guide the multicore cable 130 to the connector portion 11. The multicore cable 130 and the electric wire 330 are branched from the charging cable 13 inside the housing 10.

  FIG. 2 is an external view of the vehicle charging connector 1 as seen from the connector portion 11 side.

  The connector part 11 has an L terminal 111, an N terminal 112, a GND terminal 113, a C terminal 114, and a P terminal 115 inside a cylindrical connector housing 110. The L terminal 111 and the N terminal 112 are a pair of output terminals for supplying a single-phase 200V charging current to the vehicle. The GND terminal 113 is a grounded terminal. The C terminal 114 is a terminal for performing communication between a control device described later and the vehicle side. The P terminal 115 is a fitting detection terminal for detecting the fitting between the vehicle-side connector 91 and the connector portion 11.

  FIGS. 3A and 3B are configuration diagrams showing a configuration example of the operation restriction mechanism 3 together with its peripheral portion, where FIG. 3A shows a non-operating state and FIG. 3B shows an operating state. FIG. 4 is a perspective view showing the mover 30.

  A through hole 310 is formed at the center of the cylindrical portion 31, and the shaft portion 102 is inserted through the through hole 310. The magnet 32 is fixed to a part of the outer peripheral surface 31a of the cylindrical portion 31 in the circumferential direction so as not to be relatively rotatable. The distance from the central axis C of the shaft portion 102 to the outer peripheral surface 32 a of the magnet 32 is larger than the distance from the central axis C of the shaft portion 102 to the outer peripheral surface 31 a of the cylindrical portion 31. The portion where the magnet 32 is not fixed functions as a small diameter portion of the mover 30, and the portion where the magnet 32 is fixed functions as a large diameter portion of the mover 30.

  The magnet 32 is magnetized such that one end 321 in the circumferential direction is an S pole and the other end 322 is an N pole. Between one end 321 and the other end 322, the magnetism gradually changes from the S pole to the N pole.

  The outer peripheral surface 32a of the magnet 32 has the longest distance from the central axis C of the shaft portion 102 at the central portion 320 that is an intermediate position between the one end portion 321 and the other end portion 322, and the one end portion 321 or the other end portion. As approaching 322, the distance from the central axis C gradually decreases. That is, the distance between the virtual circle (shown by a two-dot chain line in FIG. 3) and the outer peripheral surface 32 a of the magnet 32 around the central axis C and the outer peripheral surface 32 a in the central portion 320 is one end 321 and the other end from the central portion 320. It gradually expands as it approaches the part 322.

  As for the operation part 22 of the lever member 2, the outer surface 22a which a user touches is exposed to the exterior of the housing 10 from the 2nd opening 10b. On the inner side of the operation portion 22 opposite to the outer surface 22a, a facing surface 22b facing the mover 30 is formed.

  When the electromagnet 33 is not energized, the magnet 32 is positioned below the shaft portion 102 by its own weight, as shown in FIG. In this state, the facing surface 22b of the operating portion 22 faces the outer peripheral surface 31a of the cylindrical portion 31, and the pushing operation of the operating portion 22 is allowed. FIG. 3A shows a state where the operation unit 22 is pushed. In this state, the locking of the locking portion 21 to the vehicle-side connector 91 is released. In addition, you may provide the urging member which consists of elastic bodies, such as a spring, which urges | biases the needle | mover 30 to the position shown to Fig.3 (a).

  When the electromagnet 33 is energized, one end 321 (S pole) of the magnet 32 is attracted to the electromagnet 33, and the mover 30 rotates in the direction indicated by the arrow A in FIG. Thereby, the facing surface 22 b of the operation unit 22 faces the outer peripheral surface 32 a of the magnet 32. In this Embodiment, as shown in FIG.3 (b), the outer peripheral surface 32a in the center part 320 of the magnet 32 opposes the opposing surface 22b.

  When the user does not touch the operation unit 22, the urging force of the elastic member 12 acts in a direction to separate the operation unit 22 from the mover 30, and there is a gap between the facing surface 22 b and the outer peripheral surface 32 a of the magnet 32. G is formed. The operating portion 22 can move only within the range of the gap G, and the locked state between the locking portion 21 and the vehicle-side connector 91 is not released within this range.

  When the operating portion 22 is pushed in with the outer peripheral surface 32a of the central portion 320 of the magnet 32 facing the opposing surface 22b, the opposing surface 22b comes into contact with the outer peripheral surface 32a of the magnet 32 and further movement is restricted. The That is, the mover 30 is operated by the magnetic field generated by the electromagnet 33, and the magnet 32 moves (rotates) to a position where the pushing operation of the operation unit 22 is restricted. That is, the magnet 32 also functions as an abutting member that abuts on the operation unit 22 and restricts the pressing operation by the user.

  Further, when a current is supplied to the electromagnet 33 when the operation is being pushed by the user, the operation restricting mechanism 3 causes the magnet 30 to rotate with a predetermined amount in the direction of arrow A in FIG. 32 abuts against the end of the operation unit 22 and further rotation is impossible. Thereafter, when the pushing operation is released, the operation portion 22 moves outward of the housing 10 so that the magnet 32 can rotate in the direction of arrow A, and the mover 30 rotates to the position shown in FIG. To do.

(Usage of vehicle charging connector 1)
FIG. 5 is a schematic diagram illustrating an example of a usage mode of the vehicle charging connector 1. The vehicle charging connector 1 is fitted to the vehicle-side connector 91 of the vehicle 9, and the charging current output from the control device 7 is supplied to the vehicle 9 via the charging cable 13 and the vehicle charging connector 1.

  The vehicle 9 is supplied with a charging current while being parked in the parking space 80. The parking space 80 is provided with a stand 81 that holds the vehicle charging connector 1 when not in use.

  The vehicle 9 includes a charging circuit 92 connected to a connection terminal of the vehicle-side connector 91, a charging control device 93 that controls the charging circuit 92, a storage battery 94, and electric power stored in the storage battery 94 using PWM (Pulse Width Modulation). The vehicle body 90 includes an inverter 95 that outputs a drive current switched by control, an electric motor 96 that receives supply of the drive current from the inverter 95, and a transmission 97 that changes the output of the electric motor 96 and transmits the output to the front wheels 98. ing.

  The electric motor 96 is a driving source for traveling the vehicle 9, and is, for example, an IPM (Interior Permanent Magnet Motor). The storage battery 94 is, for example, a lithium ion battery or a nickel metal hydride battery.

  The vehicle 9 may be a plug-in hybrid vehicle provided with an internal combustion engine (engine) that uses volatile oil such as gasoline as a fuel in addition to the electric motor 96. Alternatively, a rear wheel drive vehicle that transmits the output of the transmission 97 to the rear wheels 99 may be used.

  The control device 7 is connected to the vehicle charging connector 1 via the charging cable 13 and has a charging control unit 71 and a charging current supply unit 72. When the charging control unit 71 detects the fitting between the vehicle-side connector 91 and the connector unit 11, the charging control unit 71 energizes the electromagnet 33 via the charging cable 13 and the electric wire 330 inside the housing 10. Thereby, the operation control mechanism 3 becomes an operation state, and pushing operation by a user is controlled.

  Further, when the charging control unit 71 detects the fitting between the vehicle-side connector 91 and the connector unit 11, the charging control unit 71 outputs an ON signal to the charging current supply unit 72 and causes the charging current supply unit 72 to output a charging current. The charging control unit 71 may immediately output an ON signal to the charging current supply unit 72 when detecting the fitting between the vehicle-side connector 91 and the connector unit 11, and a predetermined time (for example, from the detection of the fitting) An ON signal may be output to the charging current supply unit 72 after elapse of about 3 to 5 seconds.

  The charging current supply unit 72 has a relay circuit (not shown), connects the relay circuit contacts based on an ON signal output from the charging control unit 71, and outputs a single-phase 200V AC current. This alternating current is output to the vehicle 9 side as a charging current from the L terminal 111 and the N terminal 112 of the connector portion 11 via the charging cable 13 and the multicore cable 130 inside the housing 10.

  The charging control unit 71 detects the engagement between the vehicle-side connector 91 and the connector unit 11 when communication with the vehicle 9 side is established through, for example, the C terminal 114 (see FIG. 2) of the connector unit 11.

  When the charging is completed, that is, when the electric power stored in the storage battery 94 becomes a predetermined value or more, the charging control unit 71 outputs an off signal to the charging current supply unit 72 and outputs the charging current from the charging current supply unit 72. Stop. The charging current supply unit 72 cuts off the connection of the relay circuit contacts based on the off signal output from the charging control unit 71. In addition, when the charging is completed, the charging control unit 71 stops outputting the excitation current to the electromagnet 33. As a result, the operation restriction mechanism 3 is deactivated, and a push operation by the user is possible.

  The charging control unit 71 functions to output an off signal to the charging current supply unit 72 and stop the output of the excitation current to the electromagnet 33 when an operation for interrupting charging is performed by an authorized user. You may have. Authentication as a legitimate user can be performed, for example, based on communication with an electronic key having a wireless communication function in which a unique key code possessed by the user is recorded. Further, this authentication may be performed by inputting a personal identification number or the like. Furthermore, the charging control unit 71 has a function of starting charging only when it is confirmed that the user is a legitimate user at the start of charging. You may do it.

(Operation and effect of the first embodiment)
According to the present embodiment, the following operations and effects can be obtained.

(1) Since the operation restricting mechanism 3 restricts the pushing operation of the lever member 2 during charging, the connector portion 11 can be prevented from being pulled out from the vehicle-side connector 91 during charging. Thereby, it can suppress that the charge to a vehicle is interrupted by carelessness or mischief, for example. Further, when the connector part 11 is pulled out during charging, sparks are generated between the L terminal 111 and the N terminal 112 of the connector part 11 and the terminal of the vehicle side connector 91, and the contact surfaces of these terminals are Although it may be damaged, the occurrence of such a spark can also be suppressed.

(2) The operation restricting mechanism 3 restricts the pushing operation by the user when the magnet 32 of the mover 30 comes into contact with the operation portion 22 of the lever member 2 in the operating state. Thereby, the user can be surely recognized that the pushing operation of the lever member 2 is restricted, and the user can be prevented from pulling out the vehicle charging connector 1 with a strong force.

(3) Since the operation restriction mechanism 3 is disposed inside the housing 10, it is possible to prevent the operation restriction mechanism 3 from being operated from the outside in a malicious manner. That is, an unauthorized operation from the outside of the housing 10 can be suppressed.

(4) The operation restricting mechanism 3 is configured such that the movable element 30 is half-rotated by the repulsive force and attractive force received by the magnet 32 by the magnetic field generated by the electromagnet 33, and the operation unit 22 is opposed to the outer peripheral surface 32a of the magnet 32 in this half-rotated state. The surface 22b contacts. Thereby, for example, compared with the case where the electric motor is driven, the output is decelerated and the mover 30 is rotated, the structure of the mechanism can be simplified, the occurrence of failure can be suppressed, and the first and It is possible to suppress the occurrence of malfunction due to foreign matter entering from the second openings 10a, 10b and the like.

(5) When the current is supplied to the electromagnet 33 when the operation restriction mechanism 3 is pushed by the user, the mover 30 restricts the operation of the operation unit 22 when the push operation is released. Move to position. That is, even when the user engages the connector portion 11 with the vehicle-side connector 91 and pushes the operating portion 22 of the lever member 2 and supplies current to the electromagnet 33, the pushing operation is released. Since the mover 30 rotates to the position shown in FIG. 3B, the electromagnet 33 can be energized even when the push-in operation is continued. That is, the charging control unit 71 can supply a current to the electromagnet 33 without confirming the state of the pushing operation, so that it is not necessary to provide a sensor or the like for detecting the position of the operation unit 22, for example. It becomes possible to simplify the structure of the charging connector 1 for a vehicle.

(6) Since the opposing surface 22b on the opposite side of the outer surface 22a touched by the user contacts the magnet 32, the operation unit 22 can directly receive the pressing force applied by the user by the movable element 30. That is, when the pushing operation is performed, the swing of the lever member 2 can be restricted without elastically deforming the connecting portion 23, so even if the rigidity of the connecting portion 23 is low, the user can It can be recognized that the pushing operation is in a restricted state.

(7) The magnet 32 has the longest distance between the outer peripheral surface 32a and the central axis C of the shaft portion 102 at the center portion 320 which is an intermediate position between the one end portion 321 and the other end portion 322. Since the distance from the central axis C gradually decreases as the portion 321 or the other end 322 approaches, for example, even if foreign matter enters between the magnet 32 and the electromagnet 33 from the second opening 10b, the foreign matter is scraped out. Is promoted.

The shaft 41 is connected to the central portion of the cylindrical portion 421 so as not to be relatively rotatable. The magnet 422 is magnetized such that one end 422a in the circumferential direction is an S pole and the other end 422b is an N pole. Between the one end 422a and the other end 422b, the magnetism gradually changes from the S pole to the N pole.

  The rotating member 43 has a rectangular parallelepiped shape having a thickness in the axial direction of the shaft 41, and the shaft 41 penetrates the rotating member 43 in the thickness direction. The rotating member 43 and the shaft 41 are connected so as not to be relatively rotatable by press-fitting, for example.

And penetrates the rotating member 43. Of the second side surface 43b and the fourth side surface 43d at both ends in the longitudinal direction of the rotating member 43, the second side surface 43b is formed by a curved surface having a curvature corresponding to the inner surface 100a of the housing 10A. The side surface 43d is formed as a flat surface perpendicular to the longitudinal direction.

  In the non-operating state of the operation restricting mechanism 4 in which the electromagnet 44 is not energized, the first side surface 43a is in the vertical direction of the shaft 41 by the dead weight of the rotating member 43 due to the eccentricity of the shaft 41, as shown in FIG. It will be in the state located below. When the electromagnet 44 is energized from this state, the magnet portion 42 is rotated in the direction of arrow B by the magnetic field of the electromagnet 44, and the one end portion 422 a faces the yoke 441.

  8A and 8B are schematic views of the operation restricting mechanism 4 viewed from the axial direction of the shaft 41 by cutting the main body portion 100 of the housing 10A. FIG. 8A shows the non-operating state of the operation restricting mechanism 4, and FIG. The operating states of the operation restriction mechanism 4 are shown respectively. In FIG. 8, the first and second support portions 105 and 106 are indicated by phantom lines (two-dot chain lines), and the anti-rotation portion 107 and the mover 40 (shaft 41, magnet portion 42, rotating member 43) are indicated by solid lines. ing.

  Through holes 105a and 106a are formed in the first and second support portions 105 and 106, and a shaft 41 is inserted into the through holes 105a and 106a. The inner diameters of the through holes 105 a and 106 a are larger than the outer diameter of the shaft 41, and the shaft 41 is rotatable while being supported by the first and second support portions 105 and 106.

  The rotation preventing portion 107 is erected on the inner surface 100a of the main body portion 100 of the housing 10A, and has a first end surface 107a and a second end surface 107b. In the example shown in FIG. 8, the angle formed by the first end surface 107a and the second end surface 107b is 90 °.

  In the non-operating state of the operation restricting mechanism 4, as shown in FIG. 8A, the third side surface 43 c of the rotation member 43 comes into contact with the second end surface 107 b of the rotation stopper 107, so that the rotation member 43 is The rotation is restricted by the anti-rotation portion 107. In this state, the first side surface 43 a of the rotating member 43 faces the connecting portion 23 of the lever member 2. In addition, you may provide the urging member which consists of elastic bodies, such as a spring, which urges | biases the needle | mover 40 to the position shown to Fig.8 (a).

  In the operating state of the operation restricting mechanism 4, as shown in FIG. 8B, the first side surface 43a of the rotating member 43 abuts on the first end surface 107a of the rotation preventing portion 107, so that the rotating member 43 rotates. The rotation is restricted by the stopper 107. In this state, the fourth side surface 43 d of the rotating member 43 faces the connecting portion 23 of the lever member 2. That is, the rotating member 43 rotates around the shaft 41 in an angle range of 90 °.

  The distance from the shaft 41 to the first side surface 43 a of the rotating member 43 in the non-operating state of the operation restricting mechanism 4 is based on the distance from the shaft 41 to the fourth side surface 43 d of the rotating member 43 in the operating state of the operation restricting mechanism 4. Also short. That is, in the mover 40, the distance between the rotating member 43 and the lever member 2 is changed by the rotation of the rotating member 43.

  When the operation part 22 of the lever member 2 is pushed in in the non-operating state of the operation restricting mechanism 4, the lever member 2 is shown by a two-dot chain line from the position shown by the solid line in FIG. 6 without contacting the first side surface 43a. The locked state where the locking part 21 is locked to the vehicle-side connector 91 is released. That is, the pushing operation of the operation unit 22 is allowed, and the connector unit 11 can be pulled out from the vehicle-side connector 91.

  On the other hand, when the operation portion 22 of the lever member 2 is pushed in in the operating state of the operation restriction mechanism 4, the connecting portion 23 of the lever member 2 comes into contact with the fourth side surface 43 d of the rotating member 43. As a result, the swing of the lever member 2 is restricted within a range in which the locked state between the locking portion 21 and the vehicle-side connector 91 is not released. That is, the pushing operation by the user is restricted by the rotating member 43, and the connector portion 11 cannot be removed from the vehicle-side connector 91.

  Also according to the present embodiment, the same operations and effects as (1) to (5) described for the first embodiment can be obtained. In addition, since the operation restricting mechanism 4 is disposed in the upper part of the housing space 1a of the housing 10A, the influence of foreign matter, water droplets, or the like entering from the first and second openings 10a and 10b on the operation of the operation restricting mechanism 4 is suppressed. It becomes possible to do.

  Although the first and second embodiments of the present invention have been described above, the embodiments described above do not limit the invention according to the claims. In addition, it should be noted that not all the combinations of features described in the embodiments are essential to the means for solving the problems of the invention.

  Further, the present invention can be appropriately modified and implemented without departing from the spirit of the present invention. For example, in the first and second embodiments described above, the movable elements 30 and 40 are in an operating state in which the pressing operation of the operating portion 22 of the lever member 2 is restricted by the change in the rotation position thereof, and this pressing operation is permitted. Although the configuration is such that the non-operating state can be switched, the present invention is not limited to this, and the operation restriction mechanism may be configured so that the operating state and the non-operating state can be switched by moving the mover linearly within the housing. Good.
