[0029] [Description of embodiments of this disclosure]

[0030] First, the implementation methods of this disclosure are listed and explained.

[0031] The connector device disclosed herein,

[0032] [1] is a connector device in which a first connector portion and a second connector portion can be attached and detached, the connector device having a locking portion that engages in the attachment and detachment direction between the first connector portion and the second connector portion.

[0033] According to this structure, by having a locking part that engages in the loading and unloading direction between the first connector part and the second connector part, it is possible to prevent the first connector part and the second connector part from falling off.

[0034] [2] Preferably, the locking part includes a first locking part and a second locking part. The first locking part has: an actuator disposed on one of the first connector part and the second connector part to allow the pin member to move in and out; and a pin engagement groove disposed on the other of the first connector part and the second connector part, and is embedded in the pin member to engage with the pin member in the loading and unloading direction. The second locking part maintains the engagement state of the pin engagement groove of the first locking part and the pin member.

[0035] According to this structure, by using the first locking part to restrict the relative movement of the first connector part and the second connector part in the loading and unloading direction, and by using the second locking part to maintain the engagement state of the first locking part, the detachment of the first connector part and the second connector part can be prevented. In addition, during disassembly, by moving the pin member of the first locking part, the engagement state between the pin member and the pin engagement groove can be released, making disassembly easy.

[0036] [3] Preferably, the second locking part has: a recess, disposed on one of the first connector part and the second connector part, recessed in a direction intersecting the engagement direction of the pin engagement groove and the pin member; and a protrusion, disposed on the other of the first connector part and the second connector part, embedded in the recess.

[0037] According to this structure, the second locking part can be configured as a simple structure having a recess that is recessed in a direction that intersects with the engagement method of the pin engagement groove and the pin member, and a protrusion that is embedded in the recess.

[0038] [4] Preferably, the recess and the protrusion are formed in a circular shape along the circumference of the imaginary axis, which extends in the loading and unloading direction of the first connector portion and the second connector portion and passes through the loading and unloading center.

[0039] According to this structure, the concave and convex portions are formed into a ring shape, thereby stably maintaining the engaged state of the first locking portion.

[0040] [Details of the embodiments of this disclosure]

[0041] Specific examples of the connector device of this disclosure are described below with reference to the accompanying drawings. In the drawings, for ease of description, sometimes a portion of the structure is shown enlarged or simplified. Furthermore, the dimensional ratios of the various parts sometimes differ in the drawings. The terms "parallel" and "orthogonal" in this specification include not only cases where they are strictly parallel or orthogonal, but also cases where they are substantially parallel or orthogonal to the extent that they achieve the desired effect in this embodiment. Moreover, the invention is not limited to these examples, but is shown by the claims to include all modifications within the meaning and scope equivalent to the claims.

[0042] like Figure 1 As shown, the connector assembly 10 has a first connector portion 11 and a second connector portion 12. The connector assembly 10 electrically connects, for example, a battery and a charging device mounted in a vehicle. The connector assembly 10 is configured such that the first connector portion 11 and the second connector portion 12 are detachable.

[0043] (Structure of the first connector section 11)

[0044] Figure 2 The first connector portion 11 shown is mounted on the vehicle side and electrically connected to the battery, for example.

[0045] 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.

[0046] 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.

[0047] like Figure 2 and Figure 4As 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.

[0048] 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.

[0049] 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.

[0050] like Figure 2 As shown, the generally circular end face 24a of the retaining body 24 on one side in the vertical direction X has a first groove 27 for inserting a portion of the first electrode 31 and a second groove 28 for inserting the second electrode 32. Furthermore, when the first connector 11 and the second connector 12 are assembled, the end face 24a of the retaining body 24 faces the second connector 12 in the vertical direction X. In the following description, the terms circumferential (rotational direction) and radial are sometimes used with reference to the first central axis L1, which passes through the center of the end face 24a of the retaining body 24 and is parallel to the vertical direction X. That is, when only described as "circumferential," it refers to the circumferential direction with reference to the first central axis L1; when only described as "radial," it refers to the radial direction with reference to the first central axis L1.

[0051] The first groove 27 and the second groove 28 are formed into a shape that is recessed in the upward and downward direction (X). Two first grooves 27 are provided on the radially outer side of the end face 24a. In the following description, one of the two first grooves 27 is sometimes designated as first groove 27a and the other as first groove 27b.

[0052] Two first grooves 27 are formed on opposite sides of each other at a circumferential angle of 180 degrees. Each first groove 27 is configured to appear as an annular sector when viewed from the vertical direction X. Here, "annular sector" means a shape in which a circular shape is cut into a sector at a predetermined central angle. In the following description, "annular sector" is used in the same sense. Each first groove 27 is separated from each other in the circumferential direction.

[0053] The second groove 28 is located approximately at the center of the end face 24a and is formed in a shape that is recessed in the upward and downward direction X from the end face 24a. The second groove 28 is configured to be approximately circular when viewed from the upward and downward direction X. In this embodiment, the two first grooves 27 are formed on opposite sides of the second groove 28 at a circumferential angle of 180 degrees.

[0054] The retaining body 24 has a chamfered portion 24c formed at the corner 24b of its end face 24a. The chamfered portion 24c is formed such that its diameter gradually increases from the end face 24a side, which is the top end side, to the base end side in the vertical direction X of the retaining body 24. Furthermore, the chamfered portion 24c can be formed by chamfering from a so-called pin corner using post-processing, or it can be formed into a shape as if it has been chamfered beforehand during resin molding.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] like Figure 4 As 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.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] like Figure 8 and Figure 9 As shown, the actuator 41 used in this embodiment is, for example, a device that causes the pin member 42 to reciprocate linearly in an inserting-exit manner. The actuator 41 is, for example, an electric actuator using an electric motor or the like. The actuator 41 is fixed to the base plate portion 22 constituting the housing 21. The actuator 41 is arranged in a Y-direction along with the holding portion 23 constituting the housing 21 while fixed to the base plate portion 22. Furthermore, as long as the actuator 41 is a device that causes the pin member 42 to reciprocate linearly in an inserting-exit manner as described above, a known device can be used.

[0068] (Structure of the second connector section)

[0069] like Figure 3 and Figure 5 As shown, the second connector portion 12 includes a first electrode portion 51, a second electrode portion 52, and a housing 121 that holds the first electrode portion 51 and the second electrode portion 52. The first electrode portion 51 is electrically connected to the first electrode portion 31 of the first connector portion 11. The second electrode portion 52 is electrically connected to the second electrode portion 32 of the first connector portion 11. Furthermore, in the following description, the circumferential (rotational direction) or radial direction is sometimes used with reference to the second central axis L2. The second central axis L2 passes through the center of the cylindrical protrusion 133 that constitutes the housing 121 and fits into the annular groove 26 of the first connector portion 11 (described later), and is parallel to the vertical direction X. That is, when only described as "circumferential," it refers to the circumferential direction with reference to the second central axis L2; ​​when only described as "radial," it refers to the radial direction with reference to the second central axis L2. Furthermore, in this example, with the first connector section 11 and the second connector section 12 assembled, the first central axis L1 and the second central axis L2 are aligned.

[0070] The first electrode section 51 has two first terminal modules 61.

[0071] like Figure 10As shown, the two first terminal modules 61 have the same structure. One is electrically connected to the positive high-voltage terminal 33 of the first connector section 11, and the other is electrically connected to the negative high-voltage terminal 36 of the first connector section 11. The two first terminal modules 61 are electrically connected by contacting the corresponding first plate-shaped portions 34 and 37, respectively. Furthermore, in the following description, the state in which the two first terminal modules 61 are in contact with the corresponding first plate-shaped portions 34 and 37 at their respective circumferential center positions will be described using the vertical direction X, the front-back direction Y, and the horizontal direction Z. In addition, the state in which the two first terminal modules 61 are in contact with the corresponding first plate-shaped portions 34 and 37 at their respective circumferential center positions is the state in which the first connector section 11 and the second connector section 12 are connected in the normal position. In the following description, the term "normal position" will sometimes be used with the same meaning.

[0072] like Figure 11 and Figure 12 As shown, the first terminal module 61 has a support member 62, a helical spring 63 housed in the support member 62, and a movable member 64 with elastic force of the helical spring 63. The first terminal module 61 has a connecting member 65 electrically connected to the charging device side, and a flexible conductive member 66 electrically connecting the connecting member 65 and the movable member 64.

[0073] The helical spring 63 is, for example, a compression helical spring. Various types of helical springs, such as cylindrical helical springs and conical helical springs, can be used for the helical spring 63. The helical spring 63 can be either an equally spaced helical spring or an unequally spaced helical spring. In this embodiment, the helical spring 63 is an equally spaced cylindrical helical spring.

[0074] The support member 62 has a first wall portion 71 that contacts the end of a helical spring 63, a pair of second wall portions 72 extending from the two side edges of the first wall portion 71, and a pair of limiting pieces 73 extending from the two side edges of the first wall portion 71 that are different from the two side edges from which the second wall portions 72 extend.

[0075] The first wall portion 71 is configured as a rectangular plate. The first wall portion 71 contacts the end of the helical spring 63 in the vertical direction X.

[0076] A pair of second wall portions 72 extend from the first wall portion 71 in a parallel manner. Each second wall portion 72 has a first and a second guide portion 72a, which are embedded in a portion of the movable member 64 to restrict the direction of movement of the movable member 64. These guide portions 72a are, for example, through holes in the corresponding second wall portion 72 in the left-right direction Z. In each second wall portion 72, the first and second guide portions 72a are arranged in the front-back direction Y. The first guide portion 72a has a longitudinally elongated rectangular opening, and the second guide portion 72a has a parallelogram-shaped opening. The first guide portion 72a of one second wall portion 72 and the first guide portion 72a of the other second wall portion 72 are arranged in the left-right direction Z. The second guide portion 72a of one second wall portion 72 and the second guide portion 72a of the other second wall portion 72 are arranged in the left-right direction Z. The support member 62 has a total of four guide portions 72a.

[0077] A pair of limiting plates 73 extend approximately from the center of both sides of the first wall portion 71. The width or length (length in the extending direction) of the pair of limiting plates 73 is reduced compared to the pair of second wall portions 72. That is, the limiting plates 73 become a leaf spring structure that is more easily flexed than the second wall portions 72. Therefore, for example, when the coil spring 63 is housed within the support member 62, the limiting plates 73 flex and are easily housed. The pair of limiting plates 73 bend towards their respective top ends. Therefore, the entrance portion for housing the coil spring 63 expands, thus facilitating the housing of the coil spring 63.

[0078] The movable member 64 includes a spring abutting part 81 that abuts against the helical spring 63, a contact part 82 exposed to the outside, and a connecting part 83 that connects to the flexible conductive member 66.

[0079] Both the spring abutment portion 81 and the contact portion 82 are plate-shaped members extending in the same direction, with their plate surfaces facing the vertical direction X. The spring abutment portion 81 and the contact portion 82 are flat plates that are approximately parallel to each other. The spring abutment portion 81 and the contact portion 82 are separated in the vertical direction X and are opposite to each other. The rear ends of the spring abutment portion 81 and the contact portion 82, which are on the side facing the front-rear direction Y, are connected by a first plate portion 84. The first plate portion 84 is a flat plate extending in the vertical direction X.

[0080] The spring abutment portion 81 has first and second protrusions 81a extending to the left from its left edge and second and third protrusions 81a extending to the right from its right edge. The two first protrusions 81a are arranged in a left-right Z-direction, and the two second protrusions 81a are also arranged in a left-right Z-direction. The two first protrusions 81a are respectively embedded in their corresponding first guide portions 72a. The two second protrusions 81a are respectively embedded in their corresponding second guide portions 72a. In this embodiment, the spring abutment portion 81 has the same number of protrusions as the guide portions 72a, i.e., a total of four protrusions 81a.

[0081] The contact portion 82 is configured such that the flat portion 82a on the side opposite to the spring abutment portion 81 can abut against the first plate-shaped portion 34 of the first electrode portion 31. When the first connector portion 11 and the second connector portion 12 are assembled, the flat portion 82a abuts against the first plate-shaped portion 34 of the first electrode portion 31 in the vertical direction X. Thus, the first electrode portion 31 of the first connector portion 11 and the first electrode portion 51 of the second connector portion 12 are electrically connected. Furthermore, in this example, the contact portion 82 is configured to have a flat portion 82a at the abutment portion with the first plate-shaped portion 34; however, it is also possible to adopt a structure that further includes a protrusion extending from the flat portion 82a in the vertical direction X. In this case, it can be configured to have one protrusion or multiple protrusions. Thus, as long as the contact portion 82 is electrically connected by abutting against the first electrode portion 31, its shape and other features can be appropriately modified.

[0082] The connecting portion 83 is a flat plate shape that is substantially parallel to the spring abutment portion 81 and the contact portion 82. The connecting portion 83 is located forward of the spring abutment portion 81 and the contact portion 82 in the longitudinal direction Y. The rear end of the connecting portion 83 is connected to the front end of the contact portion 82 by a second plate portion 85. The second plate portion 85, like the first plate portion 84, is a flat plate shape extending in the vertical direction X. The first plate portion 84 and the second plate portion 85 are opposite each other in the longitudinal direction Y. The second plate portion 85 is longer than the first plate portion 84 in the vertical direction X. The second plate portion 85 extends from the front end of the contact portion 82 in the longitudinal direction Y towards the spring abutment portion 81 in the vertical direction X. At this time, the second plate portion 85 connects to the connecting portion 83 at a position beyond the spring abutment portion 81.

[0083] The connecting member 65 is electrically connected to the charging device side. The connecting member 65 can be, for example, made of a plate-like member with conductivity.

[0084] The flexible conductive member 66 connects the movable member 64 and the connecting member 65. That is, the flexible conductive member 66 connects the movable member 64 and the connecting member 65 even when their relative positions change. The flexible conductive member 66 is, for example, flexible. As an example of the flexible conductive member 66, it can be configured as a flexible structure by using a braided thread formed by weaving conductive metal wires. By configuring the flexible conductive member 66 as a flexible structure, even if the movable member 64 moves within a predetermined range and changes its position relative to the connecting member 65, it can still move in sync with the movement of the movable member 64.

[0085] The second electrode section 52 has two second terminal modules 91. The two second terminal modules 91 have the same structure and are electrically connected to the second electrode section 32 of the first connector section 11.

[0086] 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.

[0087] 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.

[0088] 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.

[0089] 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.

[0090] 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.

[0091] A pair of limiting plates 103 extend from approximately the center position on both sides of the first wall portion 101. The width or length (length in the extending direction) of the pair of limiting plates 103 is reduced compared to the pair of second wall portions 102, for example. That is, the limiting plates 103 form a leaf spring structure that allows the second wall portions 102 to bend more easily. Therefore, for example, when the coil spring 93 is housed within the support member 92, the limiting plates 103 bend easily for housing. The pair of limiting plates 103 bend towards their respective top ends. Therefore, the entrance portion for housing the coil spring 93 expands, thus facilitating the housing of the coil spring 93.

[0092] The movable member 94 includes a spring abutting part 111 that abuts against the helical spring 93, a contact part 112 exposed to the outside, and a connecting part 113 that connects to the flexible conductive member 96.

[0093] Both the spring abutment portion 111 and the contact portion 112 are plate-shaped members extending in the same direction, with their plate surfaces facing the vertical direction X. The spring abutment portion 111 and the contact portion 112 are flat plates that are approximately parallel to each other. The spring abutment portion 111 and the contact portion 112 are separated in the vertical direction X and are opposite to each other. The rear ends of the spring abutment portion 111 and the contact portion 112, which are on the side facing the front-rear direction Y, are connected by a first plate portion 114. The first plate portion 114 is a flat plate that extends in the vertical direction X.

[0094] The spring abutment portion 111 has first and second protrusions 111a extending to the left from its left edge and second protrusions 111a extending to the right from its right edge. The two first protrusions 111a are arranged in a left-right Z-direction, and the two second protrusions 111a are also arranged in a left-right Z-direction. The two first protrusions 111a are respectively embedded in corresponding first guide portions 102a. The two second protrusions 111a are respectively embedded in corresponding second guide portions 102a. In this embodiment, the spring abutment portion 111 has the same number of protrusions as the guide portions 102a, i.e., a total of four protrusions 111a.

[0095] The contact portion 112 is configured such that the flat portion 112a on the side opposite to the spring abutment portion 111 can abut against the flat portion 32a of the second electrode portion 32. The flat portion 82a abuts against the flat portion 32a of the second electrode portion 32 in the vertical direction when 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 are electrically connected. Furthermore, in this example, the contact portion 112 is configured to have a flat portion 112a at the abutment portion of the flat portion 32a; however, it is also possible to adopt a structure that further includes a protrusion extending from the flat portion 112a in the vertical direction X. In this case, it can be configured to have one protrusion or multiple protrusions. Thus, as long as the contact portion 112 is electrically connected by abutting against the second electrode portion 32, its shape and other features can be appropriately modified.

[0096] The connecting portion 113 is a flat plate shape that is substantially parallel to the spring abutment portion 111 and the contact portion 112. The connecting portion 113 is located forward of the spring abutment portion 111 and the contact portion 112 in the longitudinal direction Y. The rear end of the connecting portion 113 is connected to the front end of the contact portion 112 via a second plate portion 115. The second plate portion 115, like the first plate portion 114, is a flat plate shape extending in the vertical direction X. The first plate portion 114 and the second plate portion 115 are opposite each other in the longitudinal direction Y. The second plate portion 115 is longer than the first plate portion 114 in the vertical direction X. The second plate portion 115 extends from the front end of the contact portion 112 in the longitudinal direction Y towards the spring abutment portion 111 in the vertical direction X. At this time, the second plate portion 115 connects to the connecting portion 113 at a position beyond the spring abutment portion 111.

[0097] The connecting member 95 is electrically connected to the charging device side. The connecting member 95 can be, for example, made of a plate-like member with conductivity.

[0098] 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 when their relative positions change. The flexible conductive member 96 is flexible, for example. As an example of the flexible conductive member 96, a flexible structure can be achieved by using a wire with a sheath made of a small-diameter core wire. By making the flexible conductive member 96 flexible in this way, even if the movable member 94 moves within a predetermined range and changes its position relative to the connecting member 95, it can move in sync with the movement of the movable member 94.

[0099] 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.

[0100] 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.

[0101] The base plate 122 is configured to be approximately circular.

[0102] 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.

[0103] 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.

[0104] 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.

[0105] 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.

[0106] 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.

[0107] Storage sections 131 and 132 are arranged in a Z-shape in the left-right direction. More specifically, as... Figure 6As shown, with the first connector section 11 and the second connector section 12 detached, the first terminal module 61 is housed in the storage sections 131 and 132, respectively, protruding upwards from the second terminal module 91 in the vertical direction X. Therefore, the contact portion 82 of the first terminal module 61 constituting the first electrode section 51 is positioned above the contact portion 112 of the second terminal module 91 constituting the second electrode section 52 in the vertical direction X. Consequently, when assembling the first connector section 11 and the second connector section 12, after the first electrode portion 51 of the second connector section 12 contacts the first electrode portion 31 of the first connector section 11, the second electrode portion 52 of the second connector section 12 then contacts the second electrode portion 32 of the first connector section 11. In other words, when the second electrode portion 52 of the second connector section 12 contacts the second electrode portion 32 of the first connector section 11, it necessarily becomes a state where the first electrode portion 51 of the second connector section 12 contacts the first electrode portion 31 of the first connector section 11. In this structure, detecting the electrical connection between the second electrode portions 32 and 52 as the assembly of the first connector portion 11 and the second connector portion 12 enables power supply (charging). Conversely, when the first connector portion 11 and the second connector portion 12 are disassembled, after the first electrode portion 51 of the second connector portion 12 and the first electrode portion 31 of the first connector portion 11 become non-contact, the second electrode portion 52 of the second connector portion 12 and the second electrode portion 32 of the first connector portion 11 also become non-contact. In other words, when the second electrode portion 52 of the second connector portion 12 and the second electrode portion 32 of the first connector portion 11 become non-contact, it necessarily means that the first electrode portion 51 of the second connector portion 12 and the first electrode portion 31 of the first connector portion 11 are not in contact. In this structure, detecting the disconnection of the electrical connection between the second electrode portions 32 and 52 as the disassembly of the second connector portion 12 from the first connector portion 11 can be used as a signal indicating the end of power supply (charging).

[0108] like Figure 3 and Figure 5 As shown, the first retaining portion 124 has a cylindrical protrusion 133, which is located outside the receiving portions 131 and 132 and protrudes beyond them in the vertical direction X. The cylindrical protrusion 133 is located outside the receiving portions 131 and 132 and is configured to protrude beyond them in the vertical direction X. For example, the cylindrical protrusion 133 is configured as a cylinder extending in the vertical direction X and can be inserted into the annular groove 26 of the first connector portion 11.

[0109] like Figure 3As shown, the second holding portion 125 is configured to extend forward from the first holding portion 124 in the forward-rear direction Y. The second holding portion 125 internally houses each flexible conductive member 66, 96 and each connecting member 65, 95.

[0110] Furthermore, in this embodiment, the second connector portion 12 is provided with a pin engagement groove 140 into which the pin member 42 of the actuator 41 can be inserted. The pin engagement groove 140 is formed on the mounting piece 141 that is assembled to the bottom plate portion 122. The mounting piece 141 is configured to form an arc shape mimicking the cylindrical protrusion 133 of the first retaining portion 124. The mounting piece 141 is located adjacent to the cylindrical protrusion 133 in the front-rear direction Y. More specifically, the mounting piece 141 is located behind the cylindrical protrusion 133. When the first connector portion 11 and the second connector portion 12 are assembled in the normal position, the mounting piece 141 is located opposite the actuator 41 in the front-rear direction Y. Even if the mounting piece 141 is offset from the normal position within a predetermined range, the distance between it and the actuator 41 remains constant.

[0111] The pin engagement groove 140 is recessed radially inward and is formed over a predetermined range in the circumferential direction of the assembly piece 141. Therefore, even if, for example, the first connector portion 11 and the second connector portion 12 are assembled at a position offset from their normal position in the circumferential direction within a predetermined range, the pin member 42 of the actuator 41 can be engaged as long as the pin engagement groove 140 is formed. Furthermore, by the engagement of the pin member 42 of the actuator 41 into the pin engagement groove 140, the pin engagement groove 140 and the pin member 42 engage in the vertical direction X, preventing the first connector portion 11 and the second connector portion 12 from falling off in the vertical direction X due to their own weight, etc. In this embodiment, the actuator 41 and the pin engagement groove 140 constitute the first locking portion 151.

[0112] However, when the pin member 42 is inserted into the pin engagement groove 140 and the pin member 42 and the pin engagement groove 140 are in contact in the vertical direction X, if there is only one point of contact, the state cannot be stably maintained.

[0113] On the other hand, in this embodiment, the cylindrical protrusion 133 of the second connector portion 12 is embedded in the annular groove 26 of the first connector portion 11. Therefore, when the second connector portion 12 shifts due to a contact position where the pin member 42 and the pin engagement groove 140 are in contact in the vertical direction X (the direction of gravity), the annular groove 26 and the cylindrical protrusion 133 abut against each other, thus stably maintaining the engagement state of the pin member 42 and the pin engagement groove 140. In this embodiment, the annular groove 26 and the cylindrical protrusion 133 constitute the second locking portion 152.

[0114] Explain the function of this implementation method.

[0115] In the connector device 10 of this embodiment, the first connector section 11 and the second connector section 12 are 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, power can be supplied to the first connector section 11 from the second connector section 12.

[0116] Furthermore, in the connector device 10 of this embodiment, the pin engagement groove 140 of the first locking portion 151 constituting the locking portion is inserted into the pin member 42 of the actuator 41 from the radially outer side. Therefore, the pin engagement groove 140 and the pin member 42 engage in the vertical direction X.

[0117] The effects of this implementation method are described.

[0118] (1) By having a first locking part 151 that engages in the loading and unloading direction between the first connector part 11 and the second connector part 12, it is possible to suppress the first connector part 11 and the second connector part 12 from falling off.

[0119] (2) By using the first locking part 151 to restrict the relative movement of the first connector part 11 and the second connector part 12 in the loading and unloading direction, and by using the second locking part 152 to maintain the engagement state of the first locking part 151, the detachment of the first connector part 11 and the second connector part 12 can be prevented. In addition, during disassembly, by moving the pin member 42 of the first locking part 151, the engagement state between the pin member 42 and the pin engagement groove 140 can be released, making disassembly easy.

[0120] (3) The second locking part 152 can be provided with the following simple structure: an annular groove 26, which is a recessed part that is recessed in the direction that intersects with the engagement method of the pin engagement groove 140 and the pin member 42; and a cylindrical protrusion 133, which is a protrusion that is embedded in the annular groove 26.

[0121] (4) The annular groove 26 and the cylindrical protrusion 133 are formed into a ring, thereby stably maintaining the engagement state of the first locking part 151.

[0122] (Other implementation methods)

[0123] Furthermore, the above embodiments can be implemented with the following modifications. The above embodiments and the following modifications can be combined with each other within the scope of technical inconsistency.

[0124] In the above embodiment, assuming that the first connector portion 11 and the second connector portion 12 are disassembled, the contact portion 82 of the first terminal module 61 constituting the first electrode portion 51 is positioned above the contact portion 112 of the second terminal module 91 constituting the second electrode portion 52 in the vertical direction X, but this is not a limitation. The contact portions 82 of the first terminal module 61 and the contact portions 112 of the second terminal module 91 may also be positioned at the same location in the vertical direction X. Alternatively, the same structure may be used on the first connector portion 11 side, not the second connector portion 12 side. In such a structure, the first electrode portion 31 and the second electrode portion 32 may be arranged offset in the vertical direction X on the first connector portion 11 side.

[0125] • In the above embodiments, the electrode portions 51 and 52 may also be configured to move (advance and retract) in the vertical direction X using helical springs 63 and 93 respectively, but this is not a limitation. For example, the electrode portions 51 and 52 may also be configured to move using elastic members other than helical springs, such as rubber.

[0126] Alternatively, the electrode portions 51 and 52 can each be configured as non-movable structures. Alternatively, only the first electrode portion 51 of the second connector portion 12 can be configured as movable, while the second electrode portion 52 of the second connector portion 12 can be configured as non-movable. In this case, movable members 64 and 94, or guide portions 72a and 102a that allow movable members 64 and 94 to move in a predetermined direction, can be omitted from the terminal modules 61 and 91. Similarly, the flexible conductive members 66 and 96 that connect the movable members 64 and 94 to the connecting members 65 and 95 can be omitted.

[0127] • In the above embodiment, the structure is provided with a second electrode portion 32 of the first connector portion 11 and a second electrode portion 52 of the second connector portion 12, but the structure of omitting each second electrode portion 32, 52 may also be adopted.

[0128] In the above embodiment, the structure is configured such that the first electrode portion 31, which is an elongated strip electrode portion extending in the circumferential direction, is only present in the first connector portion 11, but it is not limited to this. For example, a structure in which the circumferential electrode portion is only present in the second connector portion 12 may also be adopted. Alternatively, a structure in which the elongated strip electrode portions are present in both the first connector portion 11 and the second connector portion 12 may also be adopted.

[0129] In the above embodiment, each of the first plate-shaped portions 34 and 37 of the first electrode portion 31 of the first connector portion 11 is provided as an annular sector shape, but it is not limited to this. The first plate-shaped portions 34 and 37 only need to be relatively long in the circumferential direction, for example, they may simply be provided as sector shapes.

[0130] In the above embodiment, the pin member 42 is moved in and out by electrically driving the actuator 41, but it is not limited to this. A structure in which the pin member 42 is moved in and out manually, for example, by using a compression coil spring, can also be adopted.

[0131] • In the above embodiment, the locking part is composed of the first locking part 151 and the second locking part 152, but it is not limited to this.

[0132] like Figure 15 As shown, a structure with multiple first locking parts 151 can also be adopted. Figure 15 In the example shown, three actuators 41 and three locking slots 140 constituting the first locking part 151 are arranged circumferentially. In this way, by providing multiple first locking parts 151 in the circumferential direction, the first connector part 11 and the second connector part 12 can be stably held in a connected state using only the first locking parts 151.

[0133] In the above embodiment, it is assumed that the actuator 41 causes the pin member 42 to move linearly, but it is not limited to this. An actuator that causes the pin member to move in an arc or rotation can also be used. In short, as long as an actuator that allows the pin member to move in and out is provided on one of the first connector portion 11 and the second connector portion 12, and at least a portion of the pin member can be inserted into and engaged on the other of the first connector portion 11 and the second connector portion 12, the direction of movement (action) when the pin member moves in and out is not particularly limited.

[0134] In the above embodiment, it is assumed that the connector device 10 is used for an electrical connection between the vehicle (battery) and the charging device, but its application is not limited to this. As another example, it can also be used as a connector device for an electrical connection between a robot and a charging device. Furthermore, it is not limited to charging the battery; for example, it can be used as a connector device between a motor and an inverter. In this case, preferably, for supplying three-phase alternating current, the first electrode portion uses three terminals, and the terminals are arranged circumferentially offset by 120 degrees.

[0135] This disclosure includes the following methods. Reference numerals are used in the accompanying drawings to indicate several structural elements of the illustrative embodiments, without limitation, and are merely aids in understanding. Some of the items described in the following methods may be omitted, or several items described in the methods may be selected or combined.

[0136] [Appendix 1] Several embodiments of this disclosure include a connector device (10) comprising a first connector portion (11), a second connector portion (12), and one or more locking portions (151).

[0137] The second connector (12) is configured to be loaded and unloaded relative to the first connector (11) by moving along the loading and unloading direction;

[0138] The locking part (151) is configured to restrict the movement of the second connector part (12) in the mounting / unmounting direction when the second connector part (12) is mounted on the first connector part (11).

[0140] [Note 3] In several installation examples, the second connector part (12) may have a pin engagement part (140), and the locking part (151) may have a pin (pin member 42) configured to engage with the pin engagement part (140).

[0142] The locking part (151) has a pin (pin member 42) configured to engage with the pin engagement groove part (140).

[0143] [Note 5] In several installation examples, the connector device (10) may also have a plurality of locking portions (151) arranged circumferentially along the peripheral wall (33) or the annular groove (26).

[0144] [Note 6] In several installation examples, the plurality of locking parts (151) may also have the same structure.

[0145] [Note 7] In several installation examples, at least one of the first connector portion (11) and the second connector portion (12) may have one or more elongated electrode portions (31) extending circumferentially along the peripheral wall (33) or the annular groove portion (26).

[0146] [Note 8] In several installation examples, each of the elongated electrode portions (31) may have a positive terminal (33) and a negative terminal (36), the positive terminal (33) and the negative terminal (36) being arranged along the circumferential direction.

[0148] [Note 10] In several installation examples, the terminal module (61) may also have a connection surface (planar portion 82a) that can be electrically connected to the elongated electrode portion (31), wherein the circumferential length of each elongated electrode portion (31) is longer than the circumferential length of the connection surface (82a).
