Description

  The present invention relates to a power supply connector for rapid charging used in an electric vehicle or the like.

  In recent years, electric vehicles that do not use fossil fuels have attracted attention from the viewpoint of global environmental problems. An electric vehicle is equipped with a driving battery and can be driven by electricity charged in the battery.

  In order to charge an electric vehicle, there are a method using a normal household power source and a method using a special charging device for quick charging. The method using a household power source does not require a special connector, but requires a long time for charging. Therefore, charging is performed using a time when the automobile is not used, such as at night. On the other hand, in order to perform long-distance continuous operation, it is necessary to perform quick charging at power supply stations provided at various places, as in the case of refueling at a conventional gas station.

  As such a power supply connector for an electric vehicle, for example, a case, a connector main body slidably attached to the case and accommodating a plurality of terminals, and a pipe slidably attached to the connector main body in a coaxial direction There is a power supply connector that includes a handle and a lever, and the handle is advanced by turning the lever so that the connector main body is fitted to the connector main body of the power receiving side connector (Patent Document 1).

Japanese Patent Laid-Open No. 06-188044

  Here, since it is necessary to insert a relatively large terminal for connector connection for quick charging, the connector insertion resistance is large. On the other hand, the connector of Patent Document 1 assists the joint resistance between the power feeding connector and the power receiving connector with a lever. However, it is difficult for the user to grasp when to operate the lever, and the connectors are connected even if the lever is operated without the spacing and orientation between the connectors being in a predetermined state. The connection workability was not always good. Further, there is a problem that it is difficult for the operator to intuitively understand the movement of the connector and the operation of the lever.

  FIG. 12 is a schematic view showing a conventional power supply connector 100. The power supply connector 100 is provided with a connector main body 101 at the tip, and is connected to a power receiving connector (not shown). The operator performs connector connection work while holding the handle 103 in his / her hand. At this time, in order to receive connection resistance (such as insertion friction of a plurality of terminals) F1 with the power receiving connector, the operator needs to push in with the same force F2.

  In addition, since the handle 103 is not formed on the central axis of the connector main body of the power supply connector 100, a moment M1 is generated in the handle 103 by the force F1. For this reason, the operator needs to generate a force of moment M2 in response thereto. That is, it is difficult for the operator to grasp the balance of the force required for connector connection, and the connector connection work is sensibly difficult.

  The present invention has been made in view of such a problem, and an object of the present invention is to provide a power supply connector for an electric vehicle that does not require a large force and can be easily connected by an operator. And

  In order to achieve the above-described object, the present invention provides a power feeding connector for an automobile, comprising a connector main body, a case for housing the connector main body, and a gripping member attached to the case. The connector body and the gripping member are slidable in substantially the same axial direction, and when the gripping member is moved forward with respect to the case, the connector body is moved along with the movement of the gripping member. The power supply connector is capable of moving forward with respect to the case.

  When the power feeding connector is connected to the power receiving side connector, a locking means for holding the connection with the power receiving side connector is provided, and the holding member is provided with a release mechanism for releasing the locking means. Also good.

  The release mechanism may be provided with a display unit that can be distinguished from the state where the power supply connector is locked and the state where the power supply connector is released.

  The gripping member is preferably provided with a handle, and a part of the handle is preferably disposed on an extension line of the central axis of the connector body.

  The gripping member is provided with a speed reduction mechanism, and the movement of the gripping member and the connector main body with respect to the case is performed via the speed reduction mechanism, and when the gripping member is moved with respect to the case, It is desirable that the moving distance of the connector main body with respect to the case is smaller than the moving distance of the gripping member with respect to the case.

The case is provided with an arm member, and the speed reduction mechanism is provided such that the vicinity of the end of the arm member is turnable on the case, and the vicinity of the other end of the arm member is rotated with the gripping member. are connected movement, the arm member includes a connecting portion between the case and between the connecting portion between the gripping member, pivotally connected to said connector body, said gripping member relative to said case If it does, the said arm member may rotate centering | focusing on a connection part with the said case, and the said connector main body may move with respect to the said case with rotation of the said arm member.

  The case is provided with a first gear and a second gear having a smaller number of teeth than the first gear, and the speed reduction mechanism includes the first gear and the second gear on the case. The gripping member is connected to the first gear via a first connecting member, and the linear movement of the gripping member is converted into the rotational movement of the first gear. The connector main body is connected to the second gear via a second connecting member, and the movement of the second gear in the rotational direction is converted into the movement of the connector main body in the linear direction, When the gripping member is moved with respect to the case, the first gear rotates, the rotation is transmitted to the second gear, and the connector body moves relative to the case as the second gear rotates. You may move.

  The connector main body is provided with a pulley, and the speed reduction mechanism is configured such that one end of a belt hung on the pulley is fixed to the case, and the other end of the belt is connected to the gripping member. When the gripping member is moved with respect to the case, the pulley may be moved with respect to the case via the belt, and the connector main body may be moved with respect to the case.

  The gripping member may be slidable with respect to the case via a parallel link.

  According to the present invention, when the gripping member is pushed into the case, the connector main body moves in the same direction. Therefore, it is easy for the operator to grasp the movement of the connector body, and to easily grasp the sense in the work. Therefore, the connector connection workability for connecting the power feeding connector to the power receiving connector is excellent.

  In addition, if a lock mechanism is provided that keeps the power connector connected to the power receiving connector while the power connector is connected to the power receiving connector, the power connector can be disconnected even if the cable is accidentally pulled. There is no end. Further, since the lock mechanism can be easily released by the release mechanism, the workability is excellent.

  Moreover, the state in which the lock mechanism is locked and the released state can be easily visually confirmed. For this reason, the worker can easily grasp the connection state between the power feeding connector and the power receiving connector.

  In addition, a handle portion that becomes a handle when an operator handles the power supply connector is provided on the central axis of the connector main body. For this reason, generation | occurrence | production of the moment mentioned above at the time of a connector connection is suppressed, and it is excellent in workability | operativity.

  In addition, a deceleration mechanism is provided inside the power supply connector. By reducing the movement distance of the connector body relative to the movement distance of the gripping member, the gripping member can be operated with a force smaller than the resistance that the connector body receives when joining the power receiving connector. Can be moved. Therefore, the connector connection work can be performed with a smaller force.

  In addition, as a speed-reduction mechanism, an arm member may be provided and the lever principle may be used, or a gear using a gear may be used, or a pulley may be used. In any case, the force for pushing the gripping member may be made smaller than the connection resistance received by the connector body.

  Moreover, if sliding with a holding member and a case is performed using a parallel link, the shakiness between a holding member and a case can be suppressed.

  ADVANTAGE OF THE INVENTION According to this invention, the electric power feeding connector for electric vehicles which does not require big force and can perform a connection work sensuously also for an operator can be provided.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1A and 1B are schematic views showing a power supply connector 1, in which FIG. 1A is a side view and FIG. 1B is a side cross-sectional view. In the present invention, the state shown in FIG. 1 is referred to as a normal state. In the following drawings, illustration of cables and the like is omitted. The power supply connector 1 mainly includes a gripping member 3, a case 9, and a connector main body 11.

  As shown in FIGS. 1A and 1B, the gripping member 3 has a handle 5 at one end (rear). The handle 5 is a part that an operator holds when handling the power supply connector 1. Here, at least a part of the handle 5 is disposed on an extension line of the central axis of the connector main body 11 (the B line in FIG. 1B and an axis in the movement direction of the connector main body, which will be described later). It is formed so that. Various structures can be accommodated inside the gripping member 3. A case 9 is provided at the other end (front) of the gripping member 3. The vicinity of the front end of the gripping member 3 is cylindrical, and a part (rear part) of the case 9 is accommodated inside the gripping member 3. The gripping member 3 can slide back and forth with respect to the case 9.

  The case 9 is a cylindrical member, and a connector main body 11 is accommodated at the front end portion of the case 9. The connector main body 11 can slide back and forth with respect to the case 9. Note that a guide mechanism (not shown) and a stopper for regulating the sliding range may be provided on the sliding portions of the gripping member 3 and the connector main body 11 with respect to the case 9.

  An arm 13 is provided inside the case 9. The arm 13 is attached to the case 9 so that the vicinity of one end thereof can be rotated by a pin 23a. Near the other off end of the arm 13, a part of the gripping member 3 (a connecting bar joined to the gripping member 3) is connected by a connecting part 15 a. In the connection part 15a, both are rotatably connected by the long hole formed in the arm 13, the pin by the side of a holding member, etc. FIG.

  A substantially central portion of the arm 13 (between the pin 23a and the connecting portion 15a) is connected to the connector main body 11 by the connecting portion 15b. The connection part 15b is the same structure as the connection part 15a. That is, when the arm 13 rotates, the connector body 11 and the gripping member 3 can move linearly with respect to the case as the arm 13 rotates.

  A lock member 17 is provided inside the case 9. The lock member 17 is rotatably attached to the case 9 by a pin 23b. A lock pin 17 a is formed at the front end of the lock member 17 so as to face upward. The lock pin 17 a is disposed at the position of the hole formed in the case 9.

  A fitting portion 17b is provided at the rear end of the lock member 17 downward. The fitting portion 17 b has a convex shape that can be fitted with the fitting portion 21. The fitting part 21 is fixed to the holding member 3 side. In a normal state, the fitting portions 17 b and 21 are not fitted to each other, and the protrusion of the fitting portion 17 b is on the protrusion of the fitting portion 21. In this state, since the fitting portion 17b is pushed upward by the fitting portion 21, the lock pin 17a does not protrude from the case 9 (hole provided in the case 9) via the pin 23b. It is held in the case 9.

  An operation unit 7 is provided inside the gripping member 3. The operation unit 7 is rotatably attached to the gripping member 3 by a pin 23c. An end on the rear side of the operation unit 7 protrudes to the outside from the gripping member 3, and an operator can operate the operation unit 7 from the outside. In front of the operation unit 7, a lock pin 7a is provided facing downward. The lock pin 7a comes into contact with a part of the case 9 and is normally pushed up. The case 9 is provided with a recess 19 in which the lock pin 7a can be fitted on the front side of a portion that contacts the lock pin 7a in a normal state.

  FIG. 2 is an enlarged back view of part A in FIG. A display unit 25 is formed on the top of the handle 5. The display unit 25 is provided with a mark 27a. In the normal state shown in FIG. 1, the operation unit 7 is in a state where the lock pin 7a side is pushed up. Therefore, the operation unit 7 is rotated rightward in the drawing with the pin 23c as an axis. At this time, the end of the operation unit 7 is located below the display unit 25. Therefore, the mark 27a can be visually recognized on the display unit 25.

  Next, a state where the power supply connector 1 is operated will be described. 3A and 3B are views showing the power supply connector 1 in a state where the gripping member is moved, in which FIG. 3A is a side view and FIG. 3B is a side sectional view.

  As shown in FIG. 3B, when the gripping member 3 is moved forward with respect to the case 9 (in the direction of arrow C in the figure), the connecting portion 15a joined to the gripping member 3 is pushed forward. Since the connecting portion 15a moves forward, the arm 13 rotates in the right direction in the figure (the direction of arrow D in the figure) using the pin 23a as the rotation axis. As the arm 13 rotates, the connector main body 11 connected to the arm 13 by the connecting portion 15b moves in the same direction as the gripping member 3 (in the direction of arrow E in the figure).

  In addition, since the connection position with respect to the arm 13 differs between the gripping member 3 and the connector main body 11, the moving distance of the gripping member 3 with respect to the case 9 and the moving distance of the connector main body 11 are different. Specifically, if the ratio of the distances of the connecting portions 15a and 15b from the pin 23a is 2: 1, if the moving distance of the gripping member 3 relative to the case 9 is 2, the connector body 11 moves by a distance of 1. To do. That is, the mechanism such as the arm 13 functions as a speed reduction mechanism.

  Further, the gripping member 3 moves forward with respect to the case 9 so that the fitting portion 17b and the fitting portion 21 are engaged with each other. For this reason, the lock member 17 rotates about the pin 23b as a rotation axis. That is, when the fitting portion 17b side is pushed down, the lock member 17 rotates, and the lock pin 17a at the other end is pushed up. For this reason, the lock pin 17a protrudes outward from the case 9 through the hole (in the direction of arrow G in the figure). The lock member 17 may be formed with a spring or the like so as to always return to the state shown in FIG. 3 (the state in which the fitting portion 17b is pushed down).

  Further, when the gripping member 3 moves forward with respect to the case 9, the lock pin 7 a of the operation unit 7 moves in the direction of the recess 19, and the lock pin 7 a is fitted into the recess 19. For this reason, the operation unit 7 rotates about the pin 23c as a rotation axis. That is, when the lock pin 7a is pushed down, the operation unit 7 is rotated and the other end is pushed up (in the direction of arrow F in the figure). The operation unit 7 may be formed with a spring or the like so as to always return to the state shown in FIG. 3 (the state in which the lock pin 7a is pushed down).

  When the lock pin 7 a is fitted into the recess 19, the movement of the gripping member 3 with respect to the case 9 is locked. That is, the operation unit 7 functions as a lock unit that locks the movement of the gripping member 3 (and the connector main body 11) with respect to the case 9, and operates the operation unit 7 (external to the operation unit 7). By pushing down the end part), it functions as a release mechanism for releasing the lock.

  FIG. 4 is an enlarged view of the back surface of the part A in FIG. 3, and corresponds to FIG. In the state shown in FIG. 3, the operation unit 7 is in a state where the lock pin 7 a side is pushed down. Therefore, the operation part 7 will be in the state rotated to the left direction in the figure centering on the pin 23c. At this time, the end of the operation unit 7 is positioned so as to cover the display unit 25. Therefore, the mark 27a on the display unit 25 cannot be visually recognized.

  That is, by confirming the presence or absence of the mark 27a on the display unit 25, the state of the operation unit 7 can be visually recognized. That is, the operation unit 7 can easily visually recognize whether the power feeding connector 1 is in a locked state (the state shown in FIG. 3) or is unlocked. In addition, the method of visually recognizing the state of the operation unit 7, the arrangement of the display unit, the mark, and the like are not limited to the illustrated example, and the operation unit 7 can be viewed in a locked state and a released state. Either method is acceptable.

  A parallel link may be used for the sliding portion between the gripping member 3 (or the connector main body 11) and the case 9. FIG. 5 is an enlarged view of the vicinity of the sliding portion between the gripping member 3 and the case 9, and FIG. 5A is a state in which the gripping member 3 is retracted with respect to the case 9 (the state of FIG. 1 in a normal state). 5 (b) shows a state in which the gripping member 3 has advanced with respect to the case 9 (the state in FIG. 3).

  As shown in FIG. 5, a plurality of links 29a, 29b are arranged substantially in parallel, and the vicinity of both ends of each of the links 29a, 29b is rotatably connected by the holding member 3 and the case 9 and pins 31a, 31b. When the gripping member 3 is moved relative to the case 9, the links 29a and 29b rotate about the pins 31a and 31b, respectively, and move relative to each other (the gripping member 3 moves forward (see FIG. (Move in the middle arrow H direction)). By using such a parallel link, rattling is unlikely to occur when the gripping member 3 (or the connector main body 11) and the case 9 slide, and the movement range can be restricted.

  Next, a method for using the power supply connector 1 will be described. First, as shown in FIG. 6, the power supply connector 1 in a normal state is opposed to the power reception connector 33 as a target. Specifically, the tip of the case 9 is inserted into the recess on the power receiving connector side. A connector body 37 is accommodated in the power receiving connector 33. In this state, the male and female terminals of the connector bodies 11 and 37 are arranged with a slight gap so that they are not yet connected.

  In a state where the case 9 is disposed on the power receiving connector 37 side, a recess 35 is formed on the inner surface on the power receiving connector 37 side at a position corresponding to the lock pin 17a. In order to align the positions of the lock pin 17a and the recess 35 and the positions of the male and female terminals described above, a guide or the like for positioning with the power receiving connector side may be formed on the outer surface of the case 9.

  Next, as shown in FIG. 7, the holding member of the power supply connector 1 is pushed into the power receiving connector 33 (in the direction of arrow C in the figure). Here, the case 9 comes into contact with the power receiving connector 33, is fixed, and cannot be pushed further. Therefore, as described above, the connector body 11 moves forward relative to the case 9 by moving the gripping member 3 forward relative to the case 9 (in the direction of arrow E in the figure). Therefore, the connector body 11 protrudes from the front of the case 9 and is connected to the connector body 37 on the power receiving connector side.

  Here, when the ratio of the moving distance between the gripping member 3 and the connector main body 11 with respect to the case 9 is 2: 1, the gripping member has a moving distance twice as large as the connection allowance for connecting the connector main body 11 and the connector main body 37 By pushing, the connector body 11 can be moved by a distance that allows the connectors to be connected. That is, the connectors can be connected by pressing the gripping member 3 with half the force required for connecting the connectors (ie, connection resistance). The speed reduction ratio of the speed reduction mechanism is appropriately set in consideration of connection resistance and workability.

  In the state shown in FIG. 7, the lock pin 17 a is fitted into the recess 35 as described above. For this reason, the power receiving connector 33 and the power feeding connector 1 are locked in a connected state. Further, the lock pin 7 a at the end of the operation unit 7 is fitted into the recess 19. For this reason, the movement of the gripping member 3 with respect to the case 9 is locked. Therefore, even if a cable or the like (not shown) is pulled, the power feeding connector 1 is not easily detached from the power receiving connector 33.

  When the power feeding connector 1 is removed, the lock pin 7a is pushed up by pushing down the end of the operation portion 7, and the gripping member 3 is pulled back in this state, so that the fitting portion 17b moves onto the fitting portion 21. As a result, the lock by the lock pin 17a is released. For this reason, the power feeding connector 1 can be easily detached.

  As described above, according to the power supply connector 1 of the present embodiment, it is possible to easily connect to the power receiving connector without requiring a large force. In particular, in the power supply connector 1, since the pushing operation of the gripping member performed by the operator matches the connection direction of the connector main body 11, the worker can easily grasp the connection work intuitively.

  In addition, since the locking means for locking the connection between the power feeding connector 1 and the power receiving connector 33 and the operation unit 7 which is a release mechanism for releasing the locking means are formed, the connection state of the connector can be securely held and easily It can be canceled. Further, the locked state and the released state can be easily grasped. For this reason, it is excellent in workability.

  In addition, since a part of the handle 5 is formed on the extension line of the central axis of the connector main body 11, when the grip member 3 is pushed in, the generation of moment due to the reaction force due to the connection resistance between the connectors is suppressed. Can do. For this reason, the handleability of the power feeding connector is excellent.

  Moreover, the force required for the connection of connectors can be reduced by providing a deceleration mechanism for the movement of the gripping member 3 and the connector main body 11 with respect to the case 9. Moreover, the backlash between the holding member 3 and the case 9 can be reduced by performing the sliding between the holding member 3 and the case 9 by the parallel link.

  Next, another embodiment will be described. 8 and 9 are views showing a power supply connector 40 according to another embodiment, in which FIG. 8 is a side sectional view in a normal state, and FIG. 9 is a side sectional view in a state in which the gripping member 3 is moved. . Note that, in the following embodiment, the same reference numerals as those in FIGS. 1 and 3 are given to the configuration having the same function as that of the power supply connector 1, and redundant description is omitted.

  The power feeding connector 40 has substantially the same configuration as that of the power feeding connector 1, but the speed reduction mechanism is different. That is, the power feeding connector 40 includes gears 43a and 43b, which are speed reduction mechanisms, connecting portions 41a and 41b, and the like, instead of the configuration of the arm 13 and the like.

  As shown in FIG. 8, the gear 43a is obtained by connecting a large gear and a small gear on the same shaft. Further, the small gear of the gear 43a and the gear 43b are rotatably fixed to the case 9 with their teeth meshing with each other. The gear 43a is, for example, twice the diameter (twice the number of teeth) of the gear 43a than the small gear of the large gear. The gear 43b is similar to the small gear of the gear 43a.

  One end of the connecting member 41a is connected to a position displaced in the radial direction from the center of the large gear of the gear 43a. The connecting member 41a is rotatably attached to the gear 43a with a pin or the like. The other end of the connecting member 41a is rotatably connected to a part of the gripping member 3.

  Similarly, one end of the connecting member 41b is connected to a position displaced in the radial direction from the center of the gear 43b (for example, a position that is 1/2 of the displacement distance from the center of the gear 43a to the connecting position of the connecting member 41a). Is done. The connecting member 41b is rotatably attached to the gear 43b with a pin or the like. The other end of the connecting member 41b is rotatably connected to the connector body 11.

  As shown in FIG. 9, when the gripping member 3 is moved from the state shown in FIG. 8 (in the direction of arrow C in the figure), the gripping member 3 moves forward with respect to the case 9. At this time, the connecting member 41a connected to the gripping member 3 is pushed forward. Therefore, the movement of the connecting member 41a is converted into a movement in the rotational direction of the gear 43a (in the direction of arrow I in the figure).

  When the gear 43a rotates, the rotation is transmitted to the gear 43b that meshes with the gear 43a (in the direction of arrow J in the figure). As the gear 43b rotates, the rotational movement of the gear 43b is converted into a movement that moves the connecting member 41b forward. Therefore, the connector main body 11 is pushed forward by the connecting member 41b (in the direction of arrow E in the figure).

  Other operations of the lock pin and the like are the same as those of the power supply connector 1. Moreover, the ratio of the moving distance of the holding member 3 and the moving distance of the connector main body 11 can be set as appropriate by setting the gear ratio of the gears 43a and 43b (and the connecting position between the gear and the connecting member).

  According to the power feeding connector 40, the same effect as that of the power feeding connector 1 can be obtained. That is, it can be easily connected to the power receiving connector without requiring a large force.

  10 and 11 are views showing a power feeding connector 50 according to still another embodiment. FIG. 10 is a side sectional view in a normal state, and FIG. 11 is a side sectional view in a state in which the gripping member 3 is moved. is there. The power feeding connector 50 has substantially the same configuration as that of the power feeding connector 1, but the speed reduction mechanism is different. That is, the power feeding connector 50 includes a pulley 51, a belt 53, and the like, which are speed reduction mechanisms, instead of the configuration of the arm 13 and the like.

  As shown in FIG. 10, a pulley 51 is attached to the connector body 11 toward the rear. A belt 53 is hung on the pulley 51. One end of the belt 53 is fixed to the case 9. The other end of the belt 53 is connected to a part of the gripping member 3 (a connecting bar joined to the gripping member 3). That is, the belt 53 is hung on the rear side of the pulley 51 with both ends directed toward the front side of the connector.

  A spring 55 is provided between the connector main body 11 and the case 9. The spring 55 presses the connector body 11 toward the back against the case 9. That is, in the normal state, the connector body 11 is pushed into the case 9 facing backward. Accordingly, in a normal state, the pulley 51 is moved rearward with respect to the case 9.

  As shown in FIG. 11, when the gripping member 3 is moved from the state shown in FIG. 10 (in the direction of arrow C in the figure), the gripping member 3 moves forward with respect to the case 9. At this time, the end portion of the belt 53 (connection portion with the gripping member 3) is pulled forward by the gripping member 3. Since the other end portion of the belt 53 is fixed to the case 9, the pulley 51 rotates as the belt 53 moves by pulling the one end portion of the belt 53 forward (in the direction of arrow K in the figure). , Pushed forward with respect to the case 9. Therefore, the connector body 11 is pushed forward (in the direction of arrow E in the figure).

  In this case, the movement distance of the connector body 11 is ½ of the movement distance of the gripping member 3. Further, when removing the connector, the connector body 11 is pushed back into the case 9, so that the pulley 51 is pushed back. Therefore, the gripping member 3 is returned backward by the belt 53. Other operations of the lock pin and the like are the same as those of the power supply connector 1.

  According to the power supply connector 50, the same effect as that of the power supply connector 1 can be obtained. That is, it can be easily connected to the power receiving connector without requiring a large force.

  As mentioned above, although embodiment of this invention was described referring an accompanying drawing, the technical scope of this invention is not influenced by embodiment mentioned above. It is obvious for those skilled in the art that various modifications or modifications can be conceived within the scope of the technical idea described in the claims. It is understood that it belongs.

  For example, the shape of the gripping part 3 and the arrangement and shape of each component of the members inside the case 9 are not limited to the illustrated example.
