[0030] [Explanation of Embodiments of the Present Disclosure]

[0031] First, an embodiment of the present disclosure will be explained.

[0032] ​​​The connector device of the present disclosure,

[0033] [1] configured to be detachable between a first connector portion and a second connector portion, at least one of the first connector portion and the second connector portion having an elongated electrode portion that is electrically connected to an electrode portion on the other side, and that extends longer around an imaginary axis that extends in a direction in which the first connector portion and the second connector portion are detached and that passes through a center of detachment.

[0034] According to this configuration, by having the elongated electrode portion that is longer in the circumferential direction at least one of the first connector portion and the second connector portion, even if the first connector portion and the second connector portion are assembled with a circumferential offset, the offset is permitted within the range of the elongated electrode portion.

[0035] [2] Preferably, the elongated electrode portion has a positive electrode terminal and a negative electrode terminal that extend longer around the imaginary axis.

[0036] According to this configuration, by having the positive electrode terminal and the negative electrode terminal of the elongated electrode portion each extend longer around the imaginary axis, even if the first connector portion and the second connector portion are assembled with a circumferential offset, the offset is permitted within the range of each terminal.

[0037] [3] Preferably, the positive electrode terminal and the negative electrode terminal are disposed on the same circumference centered on the imaginary axis.

[0038] According to this configuration, by having the positive electrode terminal and the negative electrode terminal disposed on the same circumference centered on the imaginary axis, compared to, for example, a case in which each terminal is formed in a concentric circle shape and offset in the radial direction, the size in the radial direction can be suppressed from becoming large.

[0039] [4] Preferably, the positive electrode terminal and the negative electrode terminal are disposed on positions opposite each other in the circumferential direction of the imaginary axis.

[0040] According to this configuration, by having the positive electrode terminal and the negative electrode terminal disposed on positions opposite each other in the circumferential direction of the imaginary axis, the two terminals can be appropriately disposed apart from each other.

[0041] [5] Preferably, there is a center electrode portion for detecting connection of the first connector portion and the second connector portion on the imaginary axis.

[0042] According to this configuration, by having the center electrode portion for detecting connection of the first connector portion and the second connector portion on the imaginary axis, the size in the radial direction can be suppressed from becoming large and connection of the first connector portion and the second connector portion can be detected.

[0043] [6] Preferably, the first counterpart electrode portion electrically connected to the long electrode portion is provided at a position more protruding than the second counterpart electrode portion electrically connected to the center electrode portion, in the case where the first connector portion and the second connector portion are not connected.

[0044] According to this structure, in the case where the first connector portion and the second connector portion are not connected, the first counterpart electrode portion is protruded more than the second counterpart electrode portion, so that the first counterpart electrode portion and the long electrode portion are contacted first, and therefore, in the case where the second counterpart electrode portion and the center electrode portion are contacted, the first counterpart electrode portion is necessarily brought into a state of being in contact with the long electrode portion. Therefore, for example, in the case where the second counterpart electrode portion and the center electrode portion are contacted, the first counterpart electrode portion and the long electrode portion are not brought into a state of being not in contact, and thus, reliable power supply between the first counterpart electrode portion and the long electrode portion can be performed.

[0045] [7] Preferably, the first counterpart electrode portion and the second counterpart electrode portion are configured to be able to advance and retreat in the attachment / detachment direction of the first connector portion and the second connector portion.

[0046] According to this structure, by the center electrode portion and the long electrode portion being configured to be able to advance and retreat in the attachment / detachment direction of the first connector portion and the second connector portion, in the case where the first connector portion and the second connector portion are connected, the position of the center electrode portion and the long electrode portion can be adjusted to an appropriate position.

[0047] [Details of Embodiments of the Present Disclosure]

[0048] A specific example of a connector device of the present disclosure will be described below with reference to the drawings. In each drawing, a part of the structure is sometimes enlarged or simplified for the sake of convenience. In addition, the dimensional ratio of each part is sometimes different in each drawing. In this specification, "parallel" and "orthogonal" include not only the case of being strictly parallel and orthogonal, but also the case of being substantially parallel and orthogonal within the range in which the effects in the present embodiment function. Furthermore, the present disclosure is not limited to these examples, but is shown by the claims, including all modifications within the meaning and range equivalent to the claims.

[0049] As Figure 1 shown, the connector device 10 has a first connector portion 11 and a second connector portion 12. The connector device 10 electrically connects, for example, a battery mounted on a vehicle and a charging device. The connector device 10 is configured so that the first connector portion 11 and the second connector portion 12 can be attached and detached.

[0050] (Structure of the First Connector Portion 11)

[0051] Figure 2 The first connector portion 11 shown is mounted on the vehicle side and electrically connected to the battery, for example.

[0052] The first connector portion 11 can, for example, be mounted on the vehicle floor. In this case, the first connector portion 11 is mounted on the vehicle floor in a direction parallel to the vertical direction (gravity direction) with respect to the loading / unloading direction of the second connector portion 12. In the following description, the loading / unloading direction and the vertical direction will be described as the up-down direction. Furthermore, in the XYZ axes of each figure, the X-axis represents the up-down direction of the first connector portion 11, the Y-axis represents the front-back direction (length direction) of the first connector portion 11 orthogonal to the X-axis, and the Z-axis represents the left-right direction (width direction) of the first connector portion 11 orthogonal to the XY plane. In the following description, for convenience, the direction extending along the X-axis will be referred to as the up-down direction X, the direction extending along the Y-axis will be referred to as the front-back direction Y, and the direction extending along the Z-axis will be referred to as the left-right direction Z. Additionally, in the following description, Figure 2 In the diagram, the X arrow is set to point upwards, and the Y arrow is set to point forwards.

[0053] like Figure 2 As shown, the first connector portion 11 includes a housing 21, a first electrode portion 31 disposed on the housing 21, a second electrode portion 32 disposed on the housing 21 in the same manner as the first electrode portion 31, and an actuator 41 disposed on the housing 21. The first electrode portion 31 and the second electrode portion 32 are arranged in a Z-direction in the left-right direction.

[0054] like Figure 2 and Figure 4 As shown, the housing 21 has a base plate portion 22 and a holding portion 23 that is fitted to the base plate portion 22 and holds the first electrode portion 31 and the second electrode portion 32.

[0055] The base plate 22 is configured as a generally circular plate. A through hole extending in the vertical direction X is formed in the base plate 22. A bolt for fastening and fixing to a vehicle can be inserted into this through hole.

[0056] The retaining portion 23 is made of an insulating member, such as resin. The retaining portion 23 has: a generally circular plate-shaped retaining body portion 24; a guide portion 25 disposed on the outer periphery of the retaining body portion 24 to guide the second connector portion 12; and an annular groove portion 26 disposed between the retaining body portion 24 and the guide portion 25, a portion of the second connector portion 12 being embedded in the annular groove portion 26. The retaining body portion 24, the guide portion 25, and the annular groove portion 26 are integrally formed.

[0057] like Figure 2As shown, the substantially circular end surface 24a of the holding main body 24 on one side in the up-down direction X has a first groove portion 27 for embedding a portion of the first electrode portion 31 and a second groove portion 28 for embedding the second electrode portion 32. Further, the end surface 24a of the holding main body 24 faces the second connector portion 12 side in the up-down direction X in a state where the first connector portion 11 and the second connector portion 12 are fitted. In the following description, the circumferential direction (rotational direction) and the radial direction are sometimes used as a reference to the first central axis L1 passing through the center of the end surface 24a of the holding main body 24 and parallel to the up-down direction X. That is, in the case of only "circumferential direction" being described, it refers to the circumferential direction with the first central axis L1 as a reference, and in the case of only "radial direction" being described, it refers to the radial direction with the first central axis L1 as a reference.

[0058] The first groove portion 27 and the second groove portion 28 are formed in a shape recessed in the up-down direction X. The first groove portion 27 is provided with two on the radial direction outside of the end surface 24a. In the following description, one of the two first groove portions 27 is distinguished as a first groove portion 27a and the other as a first groove portion 27b.

[0059] The two first groove portions 27 are formed on opposite sides of 180 degrees in the circumferential direction from each other. Each first groove portion 27 is configured to appear as a ring-shaped sector when viewed in the up-down direction X. Here, the so-called "ring-shaped sector" is a shape in which a circular ring shape is cut into a sector with a predetermined central angle. In the following description, the ring-shaped sector is used in the same sense. Each first groove portion 27 is separated from each other in the circumferential direction.

[0060] The second groove portion 28 is a substantially central position of the end surface 24a and is formed in a shape recessed in the up-down direction X from the end surface 24a. The second groove portion 28 is configured to appear as a substantially circular shape when viewed in the up-down direction X. In the present embodiment, the two first groove portions 27 are formed on opposite sides of 180 degrees in the circumferential direction with the second groove portion 28 in between.

[0061] The holding main body 24 is formed with a chamfered portion 24c in a corner portion 24b thereof in the end surface 24a. The chamfered portion 24c is formed in a manner in which the diameter gradually increases from the end surface 24a side as the tip side to the base end side in the up-down direction X of the holding main body 24. Further, the chamfered portion 24c can be either of a case where it is formed by chamfering from a so-called pin angle by post-processing and a case where it is formed as a shape like it is chamfered in advance at the time of resin molding.

[0062] The main body 24 has two through holes 24d and 24e extending in the vertical direction X. One of the through holes 24d and 24e, through hole 24d, is formed at a position that is approximately aligned with the circumferential center of one first groove 27a in the circumferential direction, and is radially outward of the first groove 27a. The other through hole 24e is formed at a position that is approximately aligned with the circumferential center of another first groove 27b in the circumferential direction, and is radially outward of the first groove 27b.

[0063] like Figure 7 and Figure 8 As shown, the guide portion 25 is configured to be generally cylindrical. More specifically, the radially outer surface 25a of the guide portion 25 is circular when viewed from the vertical direction X, and the radially inner surface 25b of the guide portion 25 is inclined relative to the vertical direction X. The radially inner surface 25b is an inclined surface that expands radially outward towards the side of the second connector portion 12 opposite to the first connector portion 11 in the vertical direction X. In other words, the radially inner surface 25b is an inclined surface that gradually narrows radially inward towards the side of the second connector portion 12 opposite to the second connector portion 12 in the vertical direction X. Therefore, when connecting the first connector portion 11 and the second connector portion 12, when the second connector portion 12 comes into contact with the radially inner surface 25b of the guide portion 25, it is guided by the guide portion 25 towards the annular groove 26.

[0064] like Figure 2 As shown, the annular groove 26 is formed in a shape that is recessed in the vertical direction X relative to the guide portion 25 and the retaining body portion 24. For example, the annular groove 26 is formed as a circle when viewed from the vertical direction X.

[0065] like Figure 4 As shown, the first electrode section 31 has a positive electrode high voltage terminal 33 and a negative electrode high voltage terminal 36.

[0066] The positive high voltage terminal 33 has a first plate-shaped portion 34 facing the second connector portion 12 when the first connector portion 11 and the second connector portion 12 are assembled, and a second plate-shaped portion 35 protruding to the side opposite to the second connector portion 12.

[0067] like Figure 4As shown, the first plate-shaped portion 34 is configured to be annular-shaped when viewed from the vertical direction X. The first plate-shaped portion 34 is formed such that it can be inserted into one of the two first grooves 27a and 27b of the housing 21. Its shape when viewed from the vertical direction X is approximately similar to the shape of the first groove 27a when viewed from the vertical direction X, but its size when viewed from the vertical direction X is slightly smaller than that of the first groove 27a. The first plate-shaped portion 34 has a flat portion 34a facing the vertical direction X when inserted into the first groove 27a. The flat portion 34a faces the second connector portion 12 in the vertical direction X when the first connector portion 11 and the second connector portion 12 are assembled.

[0068] like Figure 4 As shown, the second plate-shaped portion 35 is located radially outward from the first plate-shaped portion 34 when the first electrode portion 31 is held by the holding portion 23. The second plate-shaped portion 35 is formed approximately at the center of the first plate-shaped portion 34 in the circumferential direction. When the first plate-shaped portion 34 is inserted into the first groove portion 27a, the second plate-shaped portion 35 passes through one of the two through holes 24d and 24e formed in the holding body portion 24 and extends to a side opposite to the direction facing the first plate-shaped portion 34. That is, in this embodiment, the positive electrode side high voltage terminal 33 is configured such that the first plate-shaped portion 34 faces one side of the positive electrode side high voltage terminal 33 in the vertical direction X, and the second plate-shaped portion 35 is located on the other side in the vertical direction X.

[0069] Like the positive-side high-voltage terminal 33, the negative-side high-voltage terminal 36 has a first plate-shaped portion 37 facing the second connector portion 12 when the first connector portion 11 and the second connector portion 12 are assembled, and a second plate-shaped portion 38 protruding to the side opposite to the second connector portion 12. Furthermore, the negative-side high-voltage terminal 36 and the positive-side high-voltage terminal 33 of this embodiment have the same shape.

[0070] like Figure 4As shown, the first plate-shaped portion 37, like the first plate-shaped portion 34 of the positive side high-voltage terminal 33, is configured to be annularly fan-shaped when viewed from the vertical direction X. That is, the radial length of the first plate-shaped portion 34 is equal throughout the circumference. The first plate-shaped portion 34 is formed such that it can be inserted into one of the two first slots 27a and 27b of the housing 21, and its shape when viewed from the vertical direction X is approximately similar to that of the first slot 27b when viewed from the vertical direction X, but its size when viewed from the vertical direction X is slightly smaller than that of the first slot 27b. The first plate-shaped portion 37 has a flat portion 37a facing the vertical direction X when inserted into the first slot 27b. The flat portion 37a faces the second connector portion 12 side in the vertical direction X when the first connector portion 11 and the second connector portion 12 are assembled. That is, the planar portion 37a of the negative high-voltage terminal 36 and the planar portion 34a of the positive high-voltage terminal 33 face the same direction in the vertical X direction.

[0071] like Figure 4 As shown, the second plate-shaped portion 38 is located radially outward from the first plate-shaped portion 37 when the first electrode portion 31 is held by the holding portion 23. The second plate-shaped portion 38 is formed approximately at the center of the first plate-shaped portion 37 in the circumferential direction. When the first plate-shaped portion 37 is inserted into the first groove portion 27b, the second plate-shaped portion 38 passes through one of the two through holes 24e formed in the holding body portion 24 and extends to the side opposite to the direction facing the first plate-shaped portion 37. That is, the negative electrode side high voltage terminal 36 of this embodiment is configured similarly to the positive electrode side high voltage terminal 33, such that the first plate-shaped portion 37 faces one side of the negative electrode side high voltage terminal 36 in the vertical direction X, and the second plate-shaped portion 38 is located on the other side in the vertical direction X.

[0072] The second electrode portion 32 is disposed in the left-right direction Z between the positive-side high-voltage terminal 33 and the negative-side high-voltage terminal 36 constituting the first electrode portion 31. More specifically, the second electrode portion 32 is disposed in the left-right direction Z at the center position between the positive-side high-voltage terminal 33 and the negative-side high-voltage terminal 36. The second electrode portion 32 has a generally circular planar portion 32a located on the same plane as the planar portions 34a and 37a. The planar portion 32a faces the same direction as the other planar portions 34a and 37a.

[0073] The second electrode portion 32 is configured to be approximately circular when viewed from the vertical direction X. The second electrode portion 32 is formed such that it can be inserted into the second groove portion 28 of the housing 21, and its size when viewed from the vertical direction X is slightly smaller than that of the second groove portion 28. The second electrode portion 32 faces the vertical direction X when inserted into the second groove portion 28. Furthermore, while the shapes of the second electrode portion 32 and the second groove portion 28 are set to be approximately circular when viewed from the vertical direction X, they can also be other shapes such as polygons.

[0074] As Figure 8 and Figure 9 shown, the actuator 41 used in the present embodiment is, for example, a device that makes the pin member 42 perform a reciprocating linear motion in a manner that can be withdrawn and inserted. The actuator 41 is, for example, an electric actuator that uses a motor or the like. The actuator 41 is fixed to the bottom plate portion 22 that constitutes the housing 21. The actuator 41 is arranged so as to be aligned with the holding portion 23 that constitutes the housing 21 in the front-rear direction Y in a state of being fixed to the bottom plate portion 22. Further, the actuator 41 can use a publicly known device as long as it is a device that makes the pin member 42 perform a reciprocating linear motion in a manner that can be withdrawn and inserted as described above.

[0075] (Structure of 2nd connector portion)

[0076] As Figure 3 and Figure 5 shown, the 2nd connector portion 12 has a 1st electrode portion 51, a 2nd electrode portion 52, and a housing 121 that holds the 1st electrode portion 51 and the 2nd electrode portion 52. The 1st electrode portion 51 is electrically connected to the 1st electrode portion 31 of the 1st connector portion 11. The 2nd electrode portion 52 is electrically connected to the 2nd electrode portion 32 of the 1st connector portion 11. Further, in the following description, the circumferential direction (rotational direction) or the radial direction is sometimes described using the 2nd central axis L2 as a reference, the 2nd central axis L2 passes through the center of a cylindrical protrusion portion 133 that constitutes the housing 121 and is fitted into the annular groove portion 26 of the 1st connector portion 11 described later, and is parallel along the up-down direction X. That is, in a case where only "circumferential direction" is described, it means the circumferential direction with the 2nd central axis L2 as a reference, and in a case where only "radial direction" is described, it means the radial direction with the 2nd central axis L2 as a reference. Further, in the present example, the 1st central axis L1 and the 2nd central axis L2 coincide in a state where the 1st connector portion 11 and the 2nd connector portion 12 are assembled.

[0077] The 1st electrode portion 51 has two 1st terminal modules 61.

[0078] As Figure 10As shown, the two first terminal modules 61 are identical in structure, one of which is electrically connected to the positive-side high-voltage terminal 33 of the first connector section 11, and the other of which is electrically connected to the negative-side high-voltage terminal 36 of the first connector section 11. The two first terminal modules 61 are in an electrically connected state by being brought into contact with the corresponding first plate-shaped sections 34, 37, respectively. In the following description, the up-down direction X, the front-rear direction Y, and the left-right direction Z are used in a state in which the two first terminal modules 61 are in contact with the circumferential central positions of the corresponding first plate-shaped sections 34, 37, respectively. Note that the state in which the two first terminal modules 61 are in contact with the circumferential central positions of the corresponding first plate-shaped sections 34, 37, respectively, is a state in which the first connector section 11 and the second connector section 12 are connected in a normal position, and the expression "normal position" is sometimes used in the same sense in the following description.

[0079] As shown in FIG. 1, the first terminal module 61 has a support member 62, a coil spring 63 housed in the support member 62, and a movable member 64 that is elastically acted on by the coil spring 63. The first terminal module 61 has a connection member 65 that is electrically connected to the charging device side, and a flexible conductive member 66 that electrically connects the connection member 65 and the movable member 64. Figure 11 Figure 12 As shown, the first terminal module 61 has a support member 62, a coil spring 63 housed in the support member 62, and a movable member 64 that is elastically acted on by the coil spring 63. The first terminal module 61 has a connection member 65 that is electrically connected to the charging device side, and a flexible conductive member 66 that electrically connects the connection member 65 and the movable member 64.

[0080] The coil spring 63 is, for example, a compression coil spring. The coil spring 63 can use various coil springs such as a cylindrical coil spring, a conical coil spring, and the like. The coil spring 63 can be either an equal-interval coil spring or a non-equal-interval coil spring. The coil spring 63 of the present embodiment is a cylindrical coil spring of equal intervals.

[0081] The support member 62 has a first wall section 71 that contacts the end of the coil spring 63, a pair of second wall sections 72 that extend from both side edges of the first wall section 71, and a pair of limiting pieces 73 that extend from both side edges of the first wall section 71 different from the both side edges from which the second wall sections 72 extend.

[0082] The first wall section 71 is configured in a rectangular plate shape. The first wall section 71 contacts the end of the coil spring 63 in the up-down direction X.

[0083] ​A pair of the second wall portions 72 are formed so as to extend from the first wall portion 71 in a mutually parallel manner. Each of the second wall portions 72 has first and second guide portions 72a which are embedded in a portion of the movable member 64 so as to restrict the moving direction of the movable member 64. These guide portions 72a are, for example, through holes which pass through the corresponding second wall portion 72 in the left-right direction Z. In each of the second wall portions 72, the first and second guide portions 72a are arranged in the front-rear direction Y. The first guide portions 72a have openings which are elongated rectangles in the longitudinal direction, and the second guide portions 72a have openings which are parallelograms. The first guide portion 72a of one of the second wall portions 72 is arranged in the left-right direction Z with the first guide portion 72a of the other of the second wall portions 72. The second guide portion 72a of one of the second wall portions 72 is arranged in the left-right direction Z with the second guide portion 72a of the other of the second wall portions 72. The support member 62 has a total of four guide portions 72a.

[0084] A pair of the restriction pieces 73 are formed so as to extend from the substantially central positions of the two side edges of the first wall portion 71. The pair of the restriction pieces 73 are, for example, reduced in width or length (length in the direction of extension) as compared with the pair of the second wall portions 72. That is, the restriction pieces 73 are formed as plate springs which are more easily bent than the second wall portions 72. Therefore, for example, when the coil spring 63 is housed in the support member 62, the restriction pieces 73 are bent and easily housed. The pair of the restriction pieces 73 are bent in a direction in which they are separated from each other toward the tip end side. Therefore, the entrance portion at the time of housing the coil spring 63 is enlarged, and thus the coil spring 63 is easily housed.

[0085] The movable member 64 includes a spring abutting portion 81 which abuts against the coil spring 63, a contact portion 82 which is exposed to the outside, and a connection portion 83 which is connected to the flexible conductive member 66.

[0086] The spring abutting portion 81 and the contact portion 82 are both plate-like members which extend in the same direction, with their plate surfaces facing in the up-down direction X. The spring abutting portion 81 and the contact portion 82 are formed in a substantially parallel flat plate shape. The spring abutting portion 81 and the contact portion 82 are separated from each other in the up-down direction X, and face each other. The spring abutting portion 81 and the contact portion 82 are connected at the rear end portion on one side in the front-rear direction Y by a first plate portion 84. The first plate portion 84 is formed in a flat plate shape which extends in the up-down direction X.

[0087] The spring abutting portion 81 has first and second protrusions 81a which extend from the left edge thereof to the left, and first and second protrusions 81a which extend from the right edge thereof to the right. The two first protrusions 81a are arranged in the left-right direction Z, and the two second protrusions 81a are arranged in the left-right direction Z. The two first protrusions 81a are respectively embedded in the corresponding first guide portions 72a. The two second protrusions 81a are respectively embedded in the corresponding second guide portions 72a. The spring abutting portion 81 of the present embodiment has a total of four protrusions 81a, the same number as the guide portions 72a.

[0088] The contact portion 82 is configured so that a flat surface portion 82a on the side opposite the facing surface of the spring abutting portion 81 can abut against the first plate-shaped portion 34 of the first electrode portion 31. The flat surface portion 82a abuts against the first plate-shaped portion 34 of the first electrode portion 31 in the up-down direction X in a state in which the first connector portion 11 and the second connector portion 12 are assembled. Thus, the first electrode portion 31 of the first connector portion 11 and the first electrode portion 51 of the second connector portion 12 become in an electrically connected state. In this example, the contact portion 82 is configured to have the flat surface portion 82a at the abutting portion with the first plate-shaped portion 34, but a structure in which, for example, a protrusion protruding in the up-down direction X from the flat surface portion 82a is further provided can also be employed. At this time, the structure can be configured to provide one protrusion or a plurality of protrusions. In this way, the shape and the like of the contact portion 82 can be appropriately changed as long as the contact portion 82 is configured to abut against the first electrode portion 31 to be electrically connected.

[0089] The connection portion 83 is in a flat plate shape that is substantially parallel to the spring abutting portion 81 and the contact portion 82. The connection portion 83 is positioned on the front side in the front-rear direction Y than the spring abutting portion 81 and the contact portion 82. The rear end portion of the connection portion 83 is connected to the front end portion of the contact portion 82 by a second plate portion 85. The second plate portion 85 is also in a flat plate shape that extends in the up-down direction X like the first plate portion 84. The first plate portion 84 and the second plate portion 85 face each other in the front-rear direction Y. The second plate portion 85 is longer in the up-down direction X than the first plate portion 84. The second plate portion 85 extends from the front end portion of the contact portion 82 in the front-rear direction Y toward the spring abutting portion 81 in the up-down direction X. At this time, the second plate portion 85 is connected to the connection portion 83 at a position that passes the spring abutting portion 81.

[0090] The connection member 65 is electrically connected to the charging device side. The connection member 65 can be configured, for example, by a plate-shaped member having electrical conductivity.

[0091] The flexible conductive member 66 is connected between the movable member 64 and the connection member 65. That is, the flexible conductive member 66 is connected between the movable member 64 and the connection member 65 whose positions are changed relative to each other. The flexible conductive member 66 has flexibility, for example. As an example of the flexible conductive member 66, a braided wire formed by braiding a metal wire having electrical conductivity, for example, can be employed so as to have flexibility. By configuring the flexible conductive member 66 to have flexibility in this way, even if the movable member 64 moves within a predetermined range to change the position with respect to the connection member 65, the flexible conductive member 66 can be displaced following the movement of the movable member 64.

[0092] The second electrode portion 52 has two second terminal modules 91. The two second terminal modules 91 are of the same structure and are electrically connected to the second electrode portion 32 of the first connector portion 11.

[0093] like Figure 13 and Figure 14 As shown, the second terminal module 91 has a support member 92, a helical spring 93 housed in the support member 92, and a movable member 94 for the elastic force of the helical spring 93. The second terminal module 91 has a connecting member 95 electrically connected to the charging device side, and a flexible conductive member 96 electrically connecting the connecting member 95 and the movable member 94.

[0094] The helical spring 93 is, for example, a compression helical spring. Various types of helical springs, such as cylindrical helical springs and conical helical springs, can be used. The helical spring 93 can be either an equally spaced helical spring or an unequally spaced helical spring. In this embodiment, the helical spring 93 is an equally spaced cylindrical helical spring.

[0095] The support member 92 has a first wall portion 101 that is in contact with the end of a helical spring 93, a pair of second wall portions 102 extending from the two side edges of the first wall portion 101, and a pair of limiting pieces 103 extending from the two side edges of the first wall portion 101 that are different from the two side edges extending from the second wall portions 102.

[0096] The first wall portion 101 is configured as a rectangular plate. The first wall portion 101 contacts the end of the helical spring 93 in the vertical direction X.

[0097] A pair of second wall portions 102 extend from the first wall portion 101 in a parallel manner. Each second wall portion 102 has a first and a second guide portion 102a, which are embedded in a portion of a movable member 94 to restrict the direction of movement of the movable member 94. These guide portions 102a are, for example, through holes in the corresponding second wall portion 102 in the left-right direction Z. In each second wall portion 102, the first and second guide portions 102a are arranged in the front-back direction Y. The first guide portion 102a has a longitudinally elongated rectangular opening, and the second guide portion 102a has a parallelogram-shaped opening. The first guide portion 102a of one second wall portion 102 and the first guide portion 102a of the other second wall portion 102 are arranged in the left-right direction Z. The second guide portion 102a of one second wall portion 102 and the second guide portion 102a of the other second wall portion 102 are arranged in the left-right direction Z. The support member 92 has a total of four second guide portions 102a.

[0098] A pair of restriction pieces 103 are formed extending from substantially central positions of both side edges of the first wall portion 101. The pair of restriction pieces 103 are reduced in width or length (length in the extending direction) compared with the pair of second wall portions 102, for example. That is, the restriction pieces 103 become plate spring structures that are more easily deflected than the second wall portions 102. Therefore, the restriction pieces 103 are easily deflected and accommodated, for example, when the coil spring 93 is accommodated in the support member 92. The pair of restriction pieces 103 are bent in a direction in which they are separated from each other toward the top end side. Therefore, the entrance portion when the coil spring 93 is accommodated is enlarged, and thus the coil spring 93 is easily accommodated.

[0099] The movable member 94 includes a spring abutting portion 111 that abuts against the coil spring 93, a contact portion 112 that is exposed to the outside, and a connection portion 113 that is connected to the deflectable conductive member 96.

[0100] The spring abutting portion 111 and the contact portion 112 are both plate-like members that extend in the same direction, with their plate surfaces facing the up-down direction X. The spring abutting portion 111 and the contact portion 112 have a flat plate shape that is substantially parallel to each other. The spring abutting portion 111 and the contact portion 112 are separated from each other in the up-down direction X and face each other. The spring abutting portion 111 and the contact portion 112 are connected at a rear end portion on one side in the front-rear direction Y by a first plate portion 114. The first plate portion 114 has a flat plate shape that extends in the up-down direction X.

[0101] The spring abutting portion 111 has a first and a second protrusions 111a that extend to the left from a left edge thereof and a first and a second protrusions 111a that extend to the right from a right edge thereof. The two first protrusions 111a are arranged in the left-right direction Z, and the two second protrusions 111a are arranged in the left-right direction Z. The two first protrusions 111a are respectively fitted into the corresponding first guide portions 102a. The two second protrusions 111a are respectively fitted into the corresponding second guide portions 102a. The spring abutting portion 111 of the present embodiment has the same number of protrusions 111a as the guide portions 102a, that is, a total of four protrusions 111a.

[0102] The contact portion 112 is configured so that the flat surface portion 112a on the side opposite the facing surface of the spring abutting portion 111 can abut against the flat surface portion 32a of the second electrode portion 32. The flat surface portion 82a abuts against the flat surface portion 32a of the second electrode portion 32 in the up-down direction in the state in which the first connector portion 11 and the second connector portion 12 are assembled. Thus, the second electrode portion 32 of the first connector portion 11 and the second electrode portion 52 of the second connector portion 12 become in an electrically connected state. In this example, the contact portion 112 is configured to have the flat surface portion 112a at the abutting position against the flat surface portion 32a, but a structure in which, for example, a protruding portion protruding in the up-down direction X from the flat surface portion 112a is further provided can also be employed. At this time, the structure in which one protruding portion is provided or the structure in which a plurality of protruding portions are provided can be employed. In this way, the shape and the like of the contact portion 112 can be appropriately changed as long as the contact portion 112 is configured to abut against the second electrode portion 32 and be electrically connected.

[0103] The connecting portion 113 is in a flat plate shape substantially parallel to the spring abutting portion 111 and the contact portion 112. The connecting portion 113 is positioned on the front side in the front-rear direction Y than the spring abutting portion 111 and the contact portion 112. The rear end portion of the connecting portion 113 is connected to the front end portion of the contact portion 112 by the second plate portion 115. The second plate portion 115, like the first plate portion 114, is in a flat plate shape extending in the up-down direction X. The first plate portion 114 and the second plate portion 115 are opposite each other in the front-rear direction Y. The second plate portion 115 is longer than the first plate portion 114 in the up-down direction X. The second plate portion 115 extends from the front end portion of the contact portion 112 in the front-rear direction Y toward the spring abutting portion 111 in the up-down direction X. At this time, the second plate portion 115 is connected to the connecting portion 113 at a position beyond the spring abutting portion 111.

[0104] The connecting member 95 is electrically connected to the charging device side. The connecting member 95 can be configured, for example, by a plate-shaped member having electrical conductivity.

[0105] The flexible conductive member 96 is connected between the movable member 94 and the connecting member 95. That is, the flexible conductive member 96 is connected between the movable member 94 and the connecting member 95 whose positions are changed relative to each other. The flexible conductive member 96 has flexibility, for example. As an example of the flexible conductive member 96, a wire with a covering portion configured by a core wire having a small diameter can be employed, for example, so that the flexible conductive member 96 can be configured to have flexibility. By configuring the flexible conductive member 96 to have flexibility in this way, even if the movable member 94 moves within a predetermined range and changes the position with respect to the connecting member 95, the flexible conductive member 96 can be displaced following the movement of the movable member 94.

[0106] Here, the voltage applied to the second electrode portion 52 is lower than that applied to the first electrode portion 51. Therefore, the flexible conductive member 96 constituting the second electrode portion 52 can be a wire with a sheath made of a small-diameter core wire, as described above. On the other hand, the voltage applied to the first electrode portion 51 is higher than that applied to the second electrode portion 52. Therefore, by using braided wire as described above, it is possible to cope with high voltage and has flexibility.

[0107] like Figure 3 and Figure 5 As shown, the housing 121 has a base plate portion 122 and a holding portion 123 that is fitted to the base plate portion 122 and holds the first electrode portion 51 and the second electrode portion 52.

[0108] The base plate 122 is configured to be approximately circular.

[0109] The retaining portion 123 has a first retaining portion 124 and a second retaining portion 125 extending from the first retaining portion 124 in a forward-rear direction Y. The retaining portion 123 is made of an insulating member such as resin.

[0110] The first retaining part 124 is configured to be cylindrical, for example. The first retaining part 124 is fixed to the base plate part 122 by fastening members such as bolts. The first retaining part 124 has a storage part 131 that can independently store the two first terminal modules 61 and a storage part 132 that can independently store the two second terminal modules 91.

[0111] When the storage section 131 houses the support member 62 constituting the first terminal module 61, it engages with the support member 62 of the first terminal module 61 in the vertical direction X. This restricts the support member 62 from moving from the storage section 131 in the vertical direction X.

[0112] The storage section 132 engages with the support member 92 of the second terminal module 91 in the vertical direction X when the support member 92 constituting the second terminal module 91 is housed therein. This restricts the movement of the support member 92 from the storage section 132 in the vertical direction X.

[0113] The first terminal module 61, which is housed in the storage section 131, is positioned at a position offset from the second terminal module 91, which is housed in the storage section 132, in the vertical direction X.

[0114] Storage sections 131 and 132 are arranged in a Z-shape in the left-right direction. More specifically, as... Figure 6As shown, in a state where the first connector section 11 and the second connector section 12 are detached, the first terminal module 61 is housed in the housing sections 131, 132 so as to protrude upward in the vertical direction X more than the second terminal module 91. Therefore, the contact sections 82 of the first terminal module 61 that constitute the first electrode section 51 are positioned more upward in the vertical direction X than the contact sections 112 of the second terminal module 91 that constitute the second electrode section 52. Thus, when the first connector section 11 and the second connector section 12 are assembled, after the first electrode section 51 of the second connector section 12 comes into contact with the first electrode section 31 of the first connector section 11, the second electrode section 52 of the second connector section 12 comes into contact with the second electrode section 32 of the first connector section 11. That is, when the second electrode section 52 of the second connector section 12 comes into contact with the second electrode section 32 of the first connector section 11, the first electrode section 51 of the second connector section 12 necessarily comes into contact with the first electrode section 31 of the first connector section 11. In this structure, by detecting that the second electrode sections 32, 52 are in electrical connection with each other as the first connector section 11 and the second connector section 12 are assembled, the state in which power (charge) can be supplied is achieved. On the other hand, when the first connector section 11 and the second connector section 12 are detached, after the first electrode section 51 of the second connector section 12 comes out of contact with the first electrode section 31 of the first connector section 11, the second electrode section 52 of the second connector section 12 comes out of contact with the second electrode section 32 of the first connector section 11. That is, when the second electrode section 52 of the second connector section 12 comes out of contact with the second electrode section 32 of the first connector section 11, the first electrode section 51 of the second connector section 12 necessarily comes out of contact with the first electrode section 31 of the first connector section 11. In this structure, by detecting that the second electrode sections 32, 52 are in a state in which electrical connection is released as the second connector section 12 is detached from the first connector section 11, the state in which power (charge) supply ends can be utilized as a signal.

[0115] As shown in FIG. 6, the first connector section 11 is provided with a first electrode section 31 and a second electrode section 32. The first electrode section 31 is provided with a first electrode section housing section 121 and a first electrode section contact section 122. The first electrode section housing section 121 is provided with a first electrode section housing section 121a and a first electrode section housing section 121b. The first electrode section housing section 121a is provided with a first electrode section housing section 121a1 and a first electrode section housing section 121a2. The first electrode section housing section 121b is provided with a first electrode section housing section 121b1 and a first electrode section housing section 121b2. The first electrode section contact section 122 is provided with a first electrode section contact section 122a and a first electrode section contact section 122b. The first electrode section contact section 122a is provided with a first electrode section contact section 122a1 and a first electrode section contact section 122a2. The first electrode section contact section 122b is provided with a first electrode section contact section 122b1 and a first electrode section contact section 122b2. Figure 3 Figure 5 As shown, the first holding section 124 has a cylindrical protruding section 133 that is positioned outside the housing sections 131, 132 and protrudes upward in the vertical direction X more than the housing sections 131, 132. The cylindrical protruding section 133 is positioned outside the housing sections 131, 132 and is configured to protrude upward in the vertical direction X more than the housing sections 131, 132. The cylindrical protruding section 133 is, for example, configured in a cylindrical shape that extends in the vertical direction X and is capable of being inserted into the annular groove section 26 of the first connector section 11.

[0116] As shown in FIG. 6, the first connector section 11 is provided with a first electrode section 31 and a second electrode section 32. The first electrode section 31 is provided with a first electrode section housing section 121 and a first electrode section contact section 122. The first electrode section housing section 121 is provided with a first electrode section housing section 121a and a first electrode section housing section 121b. The first electrode section housing section 121a is provided with a first electrode section housing section 121a1 and a first electrode section housing section 121a2. The first electrode section housing section 121b is provided with a first electrode section housing section 121b1 and a first electrode section housing section 121b2. The first electrode section contact section 122 is provided with a first electrode section contact section 122a and a first electrode section contact section 122b. The first electrode section contact section 122a is provided with a first electrode section contact section 122a1 and a first electrode section contact section 122a2. The first electrode section contact section 122b is provided with a first electrode section contact section 122b1 and a first electrode section contact section 122b2. Figure 3 ​As shown, the second holding portion 125 is configured to extend from the first holding portion 124 to the front side in the front-rear direction Y. The second holding portion 125 internally houses each flexible conductive member 66, 96 and each connection member 65, 95.

[0117] In addition, in the second connector portion 12 of the present embodiment, a pin engagement groove portion 140 into which the pin member 42 of the actuator 41 can be inserted is provided. The pin engagement groove portion 140 is formed in an attachment piece 141 attached to the base portion 122. The attachment piece 141 is configured to form a circular arc shape mimicking the cylindrical protrusion portion 133 of the first holding portion 124. The attachment piece 141 is provided at a position adjacent to the cylindrical protrusion portion 133 in the front-rear direction Y. More specifically, the attachment piece 141 is provided rearward of the cylindrical protrusion portion 133. The attachment piece 141 is located at a position opposite to the actuator 41 in the front-rear direction Y in a case where the first connector portion 11 and the second connector portion 12 are attached in the normal position. Even in a case where the first connector portion 11 and the second connector portion 12 are attached in a position deviated from the normal position by a predetermined range in the circumferential direction, the distance to the actuator 41 is constant as long as it is within the range in which the pin engagement groove portion 140 is formed.

[0118] The pin engagement groove portion 140 is recessed toward the radial inner side and is formed longer in a predetermined range in the circumferential direction of the attachment piece 141. Therefore, even in a case where the first connector portion 11 and the second connector portion 12 are attached in a position deviated from the normal position by a predetermined range in the circumferential direction, for example, as long as it is within the range in which the pin engagement groove portion 140 is formed, the pin member 42 of the actuator 41 can be inserted. Further, by the pin member 42 of the actuator 41 being inserted into the pin engagement groove portion 140, the pin engagement groove portion 140 and the pin member 42 are engaged in the up-down direction X, and the first connector portion 11 and the second connector portion 12 can be inhibited from falling in the up-down direction X due to the weight or the like.

[0119] However, when the pin member 42 is inserted into the pin engagement groove portion 140 and the pin member 42 and the pin engagement groove portion 140 are in contact in the up-down direction X, if the contact is only at one point, the state cannot be stably maintained.

[0120] On the other hand, in the present embodiment, the cylindrical protrusion portion 133 of the second connector portion 12 is inserted into the annular groove portion 26 of the first connector portion 11. Thus, in a case where the second connector portion 12 is deviated as a reference from the contact position at which the pin member 42 and the pin engagement groove portion 140 are in contact in the up-down direction X as the direction of gravity, the annular groove portion 26 and the cylindrical protrusion portion 133 are in abutment, and thus the engaged state of the pin member 42 and the pin engagement groove portion 140 can be stably maintained.

[0121] The effects of the present embodiment will be described.

[0122] In the connector device 10 of the present embodiment, the first connector section 11 and the second connector section 12 are configured to be detachable. By connecting the first electrode section 31 of the first connector section 11 and the first electrode section 51 of the second connector section 12, the first connector section 11 can be supplied with power from the second connector section 12.

[0123] In addition, in the first connector section 11 of the present embodiment, the first plate-shaped sections 34, 37 that constitute the first electrode section 31 are formed longer in the circumferential direction.

[0124] As shown in FIG. 1, in the case where the first connector section 11 and the second connector section 12 are assembled in the normal position, the first electrode section 51 becomes positioned at the circumferential center of each first plate-shaped section 34, 37, and each first electrode section 31 becomes electrically connected to the corresponding first electrode section 51. Figure 15 As shown in FIG. 2, in the case where the first connector section 11 and the second connector section 12 are assembled in the circumferential direction offset from the normal position, as long as the offset is within the range of the circumferential length of each first plate-shaped section 34, 37, the first electrode section 31 and the first electrode section 51 become electrically connected.

[0125] Figure 16 As shown in FIG. 3, in the case where the first connector section 11 and the second connector section 12 are assembled in the circumferential direction offset from the normal position, as long as the offset is within the range of the circumferential length of each first plate-shaped section 34, 37, the first electrode section 31 and the first electrode section 51 become electrically connected.

[0126] The effects of the present embodiment are described.

[0127] (1) By the first connector section 11 having the first electrode section 31 that is a long electrode section longer in the circumferential direction, even in the case where the first connector section 11 and the second connector section 12 are assembled in the circumferential direction offset from the first central axis L1 that is the notional axis, the offset is easily permitted within the range of the first electrode section 31.

[0128] (2) By the positive electrode-side high-voltage terminal 33 and the negative electrode-side high-voltage terminal 36 that constitute the first electrode section 31 each being longer in the circumferential direction around the first central axis L1, even in the case where the first connector section 11 and the second connector section 12 are assembled in the circumferential direction offset, each of the positive electrode-side high-voltage terminal 33 and the negative electrode-side high-voltage terminal 36 is permitted to be offset within the range of each terminal 33, 36.

[0129] (3) By the positive electrode-side high-voltage terminal 33 and the negative electrode-side high-voltage terminal 36 being disposed on the same circumference centered on the first central axis L1, compared to the case where, for example, each of the terminals 33, 36 is formed in a concentric circle shape and offset in the radial direction, the radial direction can be suppressed from becoming large.

[0130] (4) By the positive electrode-side high-voltage terminal 33 and the negative electrode-side high-voltage terminal 36 being disposed on opposite sides in the circumferential direction with the first central axis L1 as the center, the two terminals 33, 36 can be disposed appropriately separated.

[0131] ​(5) By having the second electrode portions 32, 52 as the center electrode portions for detecting the connection of the first connector portion 11 and the second connector portion 12 on the first center axis Ll, it is possible to suppress the radial enlargement and to detect the connection of the first connector portion 11 and the second connector portion 12.

[0132] (6) In the case where the first connector portion 11 and the second connector portion 12 are not connected, by the first electrode portion 51 as the first counterpart electrode portion protruding more than the second electrode portion 52 as the second counterpart electrode portion, the first electrode portion 51 comes into contact with the first electrode portion 31 first, and therefore in the case where the second electrode portion 52 comes into contact with the second electrode portion 32, the first electrode portion 51 necessarily becomes in the state of being in contact with the first electrode portion 31. Therefore, for example, in the case where the second electrode portion 52 comes into contact with the second electrode portion 32, the first electrode portion 51 does not become out of contact with the first electrode portion 31, and therefore it is possible to perform the reliable power supply between the first electrode portion 51 and the first electrode portion 31.

[0133] (7) By the first electrode portion 51 and the second electrode portion 52 being configured to be able to advance and retreat in the attaching and detaching direction of the first connector portion 11 and the second connector portion 12, it is possible to adjust the positions of the first electrode portion 51 and the second electrode portion 52 to appropriate positions in the case where the first connector portion 11 and the second connector portion 12 are connected.

[0134] (8) By the chamfered portion 24c of the guide portion 25 and the holding main body portion 24, it is possible to guide the cylindrical protruding portion 133 of the second connector portion 12 into the annular groove portion 26. In this example, the guide portion 25, the holding main body portion 24, and the annular groove portion 26 are integrally configured, and therefore, for example, compared with a structure in which the guide portion 25, the holding main body portion 24, and the annular groove portion 26 are provided as separate components and the components are assembled, it is possible to suppress the occurrence of positional deviation. Therefore, the relative positions of the first groove portion 27 and the second groove portion 28 provided to the holding main body portion 24 and the guide portion 25 or the annular groove portion 26 are also less likely to deviate. As a result, it is possible to set the positioning of the electrode portions 31, 32 of the first connector portion 11 and the electrode portions 51, 52 of the second connector portion 12 to high precision.

[0135] (Other Embodiments)

[0136] Further, the above-described embodiments can be implemented with the following modifications. The above-described embodiments and the following modified examples can be implemented in combination with each other within a range in which the technology does not contradict.

[0137] • In the above embodiment, it is assumed that the contact portion 82 of the first terminal module 61 constituting the first electrode portion 51 is positioned higher than the contact portion 112 of the second terminal module 91 constituting the second electrode portion 52 in the up-down direction X in a state where the first connector portion 11 and the second connector portion 12 are detached, but the present application is not limited to this. The contact portion 82 of the first terminal module 61 and the contact portion 112 of the second terminal module 91 can be provided at the same position in the up-down direction X. Alternatively, the same structure can be adopted on the first connector portion 11 side rather than on the second connector portion 12 side. In this case, a structure in which the first electrode portion 31 and the second electrode portion 32 are arranged staggered in the up-down direction X on the first connector portion 11 side can be adopted.

[0138] • In the above embodiment, a structure in which the electrode portions 51, 52 are made movable (advanceable and retractable) in the up-down direction X by the helical springs 63, 93, respectively, can be adopted, but the present application is not limited to this. For example, a structure in which the electrode portions 51, 52 are made movable by elastic members other than helical springs, such as rubber, can be adopted.

[0139] Alternatively, the electrode portions 51, 52 can be configured to be immovable, respectively. Alternatively, only the first electrode portion 51 of the second connector portion 12 can be configured to be movable, and only the second electrode portion 52 of the second connector portion 12 can be configured to be immovable. In this case, structures such as the movable members 64, 94 or the guide portions 72a, 102a that make the movable members 64, 94 movable in a predetermined direction can be omitted from the terminal modules 61, 91. Similarly, the flexible conductive members 66, 96 that connect between the movable members 64, 94 and the connection members 65, 95 can be omitted.

[0140] • In the above embodiment, a structure in which the second electrode portion 32 of the first connector portion 11 and the second electrode portion 52 of the second connector portion 12 are provided is adopted, but a structure in which the second electrode portions 32, 52 are omitted can be adopted.

[0141] • In the above embodiment, a structure in which only the first electrode portion 31 serving as a long electrode portion extending in the circumferential direction is provided on the first connector portion 11 is adopted, but the present application is not limited to this. For example, a structure in which only a circumferential electrode portion is provided on the second connector portion 12 can be adopted. Alternatively, a structure in which long electrode portions are provided on both the first connector portion 11 and the second connector portion 12 can be adopted.

[0142] • In the above embodiment, the first plate-shaped portions 34, 37 of the first electrode portion 31 of the first connector portion 11 are configured as annular sectors, but the present application is not limited to this. The first plate-shaped portions 34, 37 can be configured as sectors only, for example, as long as they are longer in the circumferential direction.

[0143] • In the above-described embodiment, the structure in which the pin member 42 is caused to be withdrawn and inserted by electrically driving the actuator 41 is assumed, but the structure is not limited thereto. For example, a structure in which the pin member 42 is caused to be withdrawn and inserted by hand using a compression coil spring or the like can be adopted.

[0144] • In the above-described embodiment, it is assumed that the actuator 41 causes the pin member 42 to perform linear motion, but the actuator is not limited thereto. An actuator that causes the pin member to perform circular arc motion or rotational motion can be used. In any case, as long as the structure in which the actuator that causes the pin member to be withdrawn and inserted is provided on one of the first connector portion 11 and the second connector portion 12 and at least a part of the pin member can be inserted and engaged in the other of the first connector portion 11 and the second connector portion 12 is provided, the direction of motion (action) of the pin member when the pin member is withdrawn and inserted is not particularly limited.

[0145] • In the above-described embodiment, the connector device 10 has been described as performing electrical connection between a vehicle (battery) and a charging device, but the use thereof is not limited thereto. As another example, the connector device can be used as a connector device that performs electrical connection between a robot and a charging device. In addition, the connector device is not limited to charging of a battery, and for example, a structure in which the connector device is used as a connector device between a motor and an inverter can be adopted. In this case, preferably, in order to supply three-phase alternating current, the first electrode portion uses three terminals, and the terminals are arranged at 120 degrees in the circumferential direction.
