[0031] [Description of embodiments of this disclosure]

[0032] First, embodiments of this disclosure will be described.

[0033] The charging connector disclosed herein is as follows.

[0034] (1) A charging connector mounted on a vehicle and engaging with an external charging connector connected to an external power source of the vehicle for charging a battery provided in the vehicle, the charging connector comprising: a housing having a cylindrical frame portion for inserting and removing the external charging connector; a cover closably mounted on the end side of the cylindrical frame portion; and a locking member rotatably supported on the cylindrical frame portion by means of a shaft portion between a first position and a second position, the locking member having a supported portion supported on the shaft portion, and a locking portion and a protrusion respectively protruding radially outward from the supported portion, wherein when the locking member is in the first position, the locking portion can engage with the cover in a closed state, and the protrusion is located inwardly from the end of the cylindrical frame portion along the insertion / removal direction of the external charging connector; when the locking member rotates from the first position to the second position, the locking state of the locking portion and the cover is released, and the protrusion is located outwardly from the end of the cylindrical frame portion along the insertion / removal direction. When the locking member rotates from position 1 to position 2, the protrusion is positioned to push the cover upwards, so the cover can be easily opened even when it is frozen or the cover and shell are stuck together. In addition, the protrusion transforms the action of pushing the cover upwards into the action of rotating the locking member from position 1 to position 2, thus reducing the need for additional movements by the operator.

[0035] (2) In the charging connector of (1), the locking member may further have a protrusion formed on the top surface of the locking member and extending along the extending direction of the shaft. Thus, when the operator operates the locking member, the protrusion constitutes a hook and is difficult to slide, making the operation of the locking member easier.

[0036] (3) In the charging connector of (2), the protrusion may also be located at the end of the top surface away from the cover. Thus, when the operator moves the locking member from the first position to the second position, the protrusion can easily become a hook.

[0037] (4) In any of the charging connectors in (1) to (3), an annular sealing member may be further provided, which is disposed on the inner surface of the cover and contacts the end face of the cylindrical frame portion when the cover is closed. An annular first rib extending along the inner side of the sealing member is formed on the inner surface of the cover. Thus, when the cover is provided with a sealing member as a separate component from the cover, the first rib can be used for positioning.

[0038] (5) In the charging connector of (4), a plurality of second ribs extending radially from the center of the cover toward the first rib may also be formed on the inner surface of the cover. As a result, the rigidity of the cover is improved.

[0039] (6) In the charging connector of (5), an annular third rib may be formed on the inner surface of the cover, inside the first rib, and the plurality of second ribs extend toward the first rib from the third rib. This can suppress the intersection of the plurality of second ribs at the central part and improve the formability of the cover.

[0040] (7) In any of the charging connectors in (1) to (6), the locking member may further have an isolation portion that protrudes from the outer surface of the supported portion along the extending direction of the shaft portion toward the bearing portion of the housing. Around the isolation portion, the outer surface of the supported portion and the inner surface of the bearing portion are separated from and opposite to each other. This reduces the contact area between the locking member and the housing, thus preventing operational problems caused by freezing or other factors from affecting the locking member.

[0041] (8) In any of the charging connectors in (1) to (7), the cover may have a cover body covering the cylindrical frame portion and a latched portion hooked onto the latching portion, the latched portion protruding outward from the cover body, and the outer surface of the latched portion being lower than the outer surface of the cover body facing the cylindrical frame portion. Thus, the protruding dimension of the latching portion in the outward direction of the vehicle becomes smaller.

[0042] (9) In any of the charging connectors in (1) to (8), it may further include a locking member-side springing member that springs the locking member toward the first position along the rotation direction. Thus, the protrusion transforms the action of pushing the cover up into an action in which the operator resists the springing force of the locking member-side springing member, causing the locking member to rotate from the first position toward the second position.

[0043] (10) In any of the charging connectors in (1) to (9), the cover may be rotatably mounted to the housing via a cover-side shaft portion, and further include a cover-side spring-pressing member that springs the cover toward the open state along the rotation direction. Thus, when the upward pushing action of the protrusion on the cover provides an opportunity to peel off the adhesive portion between the cover and the housing, the cover-side spring-pressing member allows the device to transition from the closed state to the open state.

[0044] (11) In the charging connector of (10), the cover-side spring-loaded member may also include a spring body portion and a spring arm portion extending from the spring body portion, and an interference portion is provided in at least one of the cover and the housing, the interference portion interfering with the spring arm portion when the cover-side spring-loaded member is installed in a posture different from the normal posture. This prevents the cover-side spring-loaded member from being installed in a posture different from the normal posture.

[0045] [Details of the embodiments of this disclosure]

[0046] Specific examples of the charging connector of this disclosure are described below with reference to the accompanying drawings. Furthermore, this disclosure is not limited to these examples, but is intended to include all variations within the meaning and scope of the claims, as shown by the claims.

[0047] [Implementation Method 1]

[0048] The charging connector of Embodiment 1 will be described below.

[0049] <About Vehicles>

[0050] First, let's explain vehicles equipped with charging connectors.

[0051] A vehicle equipped with a charging connector is an electric vehicle that has an energy storage device and a motor. The vehicle moves by using electricity from the energy storage device to drive the motor. The vehicle can be either an electric vehicle with only a motor as its drive source, or a hybrid vehicle with both a motor and an engine. The energy storage device in the vehicle is charged by electricity supplied from an external power source. The charging connector is configured to be inserted into and electrically connected to an external charging connector. The external charging connector is a connector for a charging cable extending from an external power source.

[0052] Charging methods for energy storage devices in vehicles generally include regular charging and fast charging. Fast charging achieves charging in a shorter time by using a larger current than regular charging. Regular charging assumes the use of household power or an equivalent external power source. Fast charging, on the other hand, assumes the use of a dedicated power source, such as a charging station. The charging connector described herein is assumed to be a fast charging connector.

[0053] <Charging connector in the vehicle>

[0054] Reference Figure 1 The assembly method of the charging connector in the vehicle is explained. Figure 1 This is a top view showing the charging connector 10 of Embodiment 1 and its assembly method.

[0055] The charging connector 10 is, for example, mounted on a mounting portion 100 provided on the outer surface of the vehicle body. Figure 1 An example of the mounting portion 100 is shown. The mounting portion 100 is, for example, formed as a recessed part of the panel 102 constituting the vehicle body, which is recessed towards the inside of the vehicle. A through hole 104 is formed in the panel 102 at the bottom of the mounting portion 100.

[0056] A connection portion for connecting to an external charging connector is provided on the front side of the charging connector 10. The connection portion includes a part that is inserted into and electrically connected to the external charging connector. A portion of the charging connector 10, including the connection portion, protrudes through a through hole 104 and extends to the outside of the panel 102. Another portion of the charging connector 10 is disposed on the inner side of the vehicle, closer to the panel 102. Typically, a body side cover 106 is provided in the mounting portion 100. The body side cover 106 is mounted to the panel 102 in an openable and closable manner via hinges or the like. When the body side cover 106 is closed, it covers the opening of the panel 102. When the body side cover 106 is open, the charging connector 10 is exposed and can be connected from the outside.

[0057] In this disclosure, such as Figure 1 As shown, among the mutually orthogonal X, Y, and Z directions, the X direction is parallel to the direction in which the charging connector 10 passes through the through hole 104 of the panel 102. The charging connector 10 and the external charging connector are connected in the X direction. The Z direction is, for example, the vertical direction. For example, when the charging connector 10 is provided on the side of the vehicle, the Y direction becomes the front-rear direction of the vehicle. For example, when the charging connector 10 is provided on the front or rear surface of the vehicle, the Y direction becomes the width direction of the vehicle. Hereinafter, components not in the installed state will also be described according to the directions corresponding to the X, Y, and Z directions when they are in the installed state.

[0058] <Overall Structure>

[0059] remove Figure 1 In addition, refer to Figures 2 to 7 The overall structure of the charging connector 10 is described below. Figure 2 This is a perspective view showing the charging connector 10 of Embodiment 1. Figure 3 This is an exploded perspective view showing the charging connector 10 of Embodiment 1. Figure 4 This is a front view showing the charging connector 10 of Embodiment 1. Figure 5 It is along Figure 4 A cross-sectional view of the VV line. Figure 6 This is a diagram illustrating the terminald wire 38 and its storage location. Figure 7 This is a diagram illustrating the path of the wires 30 in the charging connector 10. Furthermore, in Figure 3 The wire 30 is omitted. Additionally, in Figure 6 In the text, part of the wire with terminals 38 is omitted.

[0060] The charging connector 10 includes terminals 20, wires 30, a thermistor unit 40, a housing 50, a retainer 60, a wire cover 70, a cover unit 80, and a wire sheath 90.

[0061] <Terminal>

[0062] Terminal 20 includes connector terminal 21 and relay terminal 28. Connector terminal 21 is housed in housing 50. Connector terminal 21 connects to terminal 20 of the other side connector. The number and type of connector terminal 21 are appropriately set according to the specifications of charging connector 10. In this embodiment, connector terminal 21 includes two power terminals 22, six signal terminals 24, and one ground terminal 26. Relay terminal 28 is located between power terminals 22 and wire 30. The number of relay terminals 28 is the same as that of power terminals 22 (two in this case). Each terminal 20 is formed by pressing (bending) a metal plate.

[0063] Power terminal 22 has a parallel connection portion 23a, a terminal fixing portion 23b, and a protrusion 23c. Power terminal 22 further has a thermistor mounting portion 23d. Signal terminal 24 has a parallel connection portion 25a, a wire fixing portion 25b, and a protrusion 25c. Grounding terminal 26 has a parallel connection portion 27a, a wire fixing portion 27b, and a protrusion 27c. Relay terminal 28 has a terminal fixing portion 29a and a wire fixing portion 29b.

[0064] The connecting portions 23a, 25a, and 27a on the opposite side are the parts that are electrically connected to the connector terminals of the external charging connector. Holes for inserting screws S are formed in the terminal fixing portions 23b and 29a. The power terminal 22 and the relay terminal 28 are electrically connected and fixed by screws S in the terminal fixing portions 23b and 29a. The wire fixing portions 25b, 27b, and 29b are crimping portions. The signal terminal 24, ground terminal 26, and relay terminal 28 are crimped to the ends of their respective wires 30 via the wire fixing portions 25b, 27b, and 29b. Thus, the signal terminal 24, ground terminal 26, and relay terminal 28 are electrically connected to and fixed to their respective wires 30. Protrusions 23c, 25c, and 27c are provided in the middle of each connector terminal 21. The protrusions 23c, 25c, and 27c are the parts pressed by the retaining body 60. The thermistor mounting portion 23d is the part for mounting the thermistor unit 40.

[0065] <Wire>

[0066] One end of each wire 30 is connected to terminal 20. The other end of each wire 30 extends outward from the cable sleeve 90. When the charging connector 10 is mounted in the vehicle, the other end of each wire 30 is connected to another machine mounted in the vehicle. Such a machine is appropriately set according to the type of wire 30, for example, a battery, electronic control unit (ECU), etc. The number and type of wires 30 correspond to the number and type of connector terminals 21. In this embodiment, the wires 30 include two power lines 32, six signal lines 34, and one ground line 36. One end of the power line 32 is connected to relay terminal 28. The power line 32 is connected to power terminal 22 via relay terminal 28. One end of the signal line 34 is connected to signal terminal 24. One end of the ground line 36 is connected to ground terminal 26. One end of the thermistor wire 44 is connected to the thermistor 42.

[0067] Each wire 30 is a sheathed wire. The sheathed wire has a core wire 31a and a covering portion 31b that covers the core wire 31a. The core wire 31a is formed, for example, by twisting together multiple metal wires. The covering portion 31b is formed, for example, by extruding an insulating resin around the core wire 31a. Multiple wires 30 of different thicknesses are used as multiple wires 30. The thickness of the wire 30 is set according to the allowable current value, etc. Generally, to increase the allowable current value, the conductor cross-sectional area needs to be increased, and correspondingly, the thickness of the wire 30 becomes thicker. Furthermore, the thickness of the wire 30 is generally related to the bending difficulty of the wire 30; as the wire 30 becomes thicker, it becomes more difficult to bend. For example, when bending an easy-to-bend wire and a difficult-to-bend wire at the same angle, the radius of curvature of the difficult-to-bend wire is larger than that of the easy-to-bend wire, and correspondingly, a larger arrangement space is required.

[0068] In this example, the power line 32 is thicker than the ground line 36 and the signal line 34. Therefore, the power line 32 is more difficult to bend than the ground line 36 and the signal line 34. Additionally, the ground line 36 is thicker than the signal line 34. Therefore, the ground line 36 is more difficult to bend than the signal line 34.

[0069] <Wires with terminals>

[0070] Terminal 20 and wire 30 are integrated and electrically connected to each other by crimping during the manufacturing process of charging connector 10. Thus, a wire with integrated wire 30 and terminal 20 is sometimes referred to as a terminald wire 38. In this example, there are terminald wires 38 with integrated power line 32 and relay terminal 28, signal line 34 and signal terminal 24, and grounding wire 36 and grounding terminal 26.

[0071] like Figure 5 As shown, a shrink tube 39 can also be used to cover the wire 38 with terminals. The shrink tube 39 covers the connection portion between the wire 30 and the terminal 20. This prevents water from splashing onto the connection portion between the wire 30 and the terminal 20, and from water seeping into the covering portion 31b. For example, the shrink tube 39 covers the portion of the terminal 20 that is forward of the portion connecting the wire 30 to the portion of the wire 30 with the covering portion 31b. The shrink tube 39 is a heat-shrinkable tube 39 that shrinks by heating. The heat-shrinkable tube 39 covers the wire 38 with terminals in its large diameter state before heating. Then, when the heat-shrinkable tube 39 is heated and shrunk, it becomes a shape corresponding to the shape of the connection portion, thereby allowing it to fit tightly against the connection portion. For example, a hot melt adhesive can be provided on the inner surface of the heat-shrinkable tube 39. This allows the hot melt adhesive to fill the gaps between the heat-shrinkable tube 39 and the terminal 20, and between the heat-shrinkable tube 39 and the wire 30, improving the water resistance of the shrink tube 39. Alternatively, the hot melt adhesive may not be provided on the inner surface of the heat-shrinkable tube 39. In the terminald wire 38, the shrink tube 39 may be omitted from the connection between the wire 30 and the terminal 20 and instead exposed. Alternatively, an adhesive or other resin may be used instead of the shrink tube 39 at the connection between the wire 30 and the terminal 20 in the terminald wire 38.

[0072] <Thermistor Unit>

[0073] The thermistor unit 40 measures the temperature of the power supply circuit. In the charging connector 10 for fast charging, because a large current flows in the power supply circuit used to charge the battery, the temperature rise of the power supply circuit is correspondingly greater. By monitoring the temperature of the power supply circuit using the thermistor unit 40, excessively high temperatures in the power supply circuit can be prevented. The thermistor unit 40 includes a thermistor 42 and a thermistor wire 44. In this example, thermistors 42 are installed on a pair of power terminals 22 respectively to measure the temperature of each pair of power terminals 22. One end of the thermistor wire 44 is connected to the thermistor 42. The other end of the thermistor wire 44, like the other end of the wire 30, extends outward from the cable sleeve 90. When the charging connector 10 is mounted in a vehicle, the other end of the thermistor wire 44 is connected, for example, to the ECU. The thermistor wire 44 is thinner than the power wire 32 and the ground wire 36. Therefore, the thermistor wire 44 is easier to bend than the power wire 32 and the ground wire 36.

[0074] <Shell>

[0075] The housing 50 holds the connector terminal 21 in a predetermined position (a position where it can connect to the connector terminal 21 of an external charging connector). The housing 50 includes a housing body 51, a vehicle mounting portion 54, and a wire pressing portion 57.

[0076] The housing body 51 houses the connector terminals 21. The housing body 51 has a cylindrical frame portion 52 and multiple terminal housing portions 53. The cylindrical frame portion 52 is formed to surround the multiple terminal housing portions 53. Each of the multiple terminal housing portions 53 is formed to accommodate a corresponding connector terminal 21. At the middle portion of the terminal housing portions 53, the multiple terminal housing portions 53 and the cylindrical frame portion 52 are connected by a flat plate-shaped connecting portion. A cover unit 80 is installed at the front of the housing body 51. A retainer 60 is installed at the rear of the housing body 51.

[0077] The vehicle mounting portion 54 is used to mount the charging connector 10 to the mounting portion 100. The vehicle mounting portion 54 is formed as a plate protruding from the middle portion of the housing body 51 towards the periphery of the cylindrical frame portion 52. The vehicle mounting portion 54 is mounted to the mounting portion 100, for example, by screws S.

[0078] The wire pressing part 57 presses the middle portion of the wire 30 extending from the terminal 20. This makes it difficult for vibrations generated on the other end side of the wire 30, which is closer to the pressed portion than the part pressed by the wire pressing part 57, to be transmitted to the terminal 20, thus suppressing friction between the terminal 20 and the housing body 51. Behind the housing body 51, a block-shaped arm 56 protrudes from the cylindrical frame portion 52 in the Y direction. A wire pressing part 57 is provided at the end of the arm 56 along the protruding direction from the housing body 51. Three wire pressing parts 57 are provided. Two of the three wire pressing parts 57 press two power lines 32, and the remaining wire pressing part 57 presses a grounding wire 36.

[0079] <Maintaining Body>

[0080] The retainer 60 prevents the terminal 20 from detaching from the housing 50. The retainer 60 includes a terminal pressing portion 61 and walls 65 and 66.

[0081] The terminal pressing part 61 is pressed and housed behind the connector terminal 21 of the housing 50. This prevents the connector terminal 21 from falling off the housing 50 to the rear. The terminal pressing part 61 includes a rear cover part 62 and a plurality of protruding cylindrical parts 63.

[0082] The rear cover 62 blocks the opening at the rear of the cylindrical frame 52. Multiple through holes are formed in the rear cover 62. These through holes are located at positions corresponding to the terminal receiving portions 53. Through the through holes corresponding to the power terminal 22, the power terminal 22 and the relay terminal 28 are fastened with screws while in contact. The relay terminal 28 is disposed on the back of the rear cover. Signal lines 34 and ground lines 36 are led out from the through holes corresponding to the signal terminal 24 and the ground terminal 26.

[0083] Multiple protruding cylindrical portions 63 protrude from the rear cover portion 62 toward the front (housing 50 side). The multiple protruding cylindrical portions 63 are formed at positions corresponding to each terminal receiving portion 53. Each protruding cylindrical portion 63 communicates with each through hole. The end of each protruding cylindrical portion 63 is inserted into the corresponding terminal receiving portion 53, pressing the corresponding protrusions 23c, 25c, and 27c from the rear.

[0084] Walls 65 and 66 protrude rearward from the rear cover 62. Wall 65 separates the relay terminals 28 from each other. Additionally, wall 65 separates the relay terminals 28 from the signal terminals 24. Wall 65 also positions the relay terminals 28. The portion of the relay terminal 28 that connects to the power terminal 22 is arranged along wall 65. Wall 66 separates the terminal 20 storage space and the drainage space inside the cable sheath 90. This prevents dust and other contaminants from entering the drainage space from the drain outlet 93 from reaching the terminal 20 storage space. Therefore, it inhibits dust and other contaminants from adhering to the terminals 20.

[0085] The housing 50 and the retainer 60 are provided with locking portions. In this example, the locking portions include a locking protrusion formed on the housing 50 and a locking tab formed on the retainer 60. The housing 50 and the retainer 60 are maintained in a mutually mounted state by the locking tab engaging with the locking protrusion.

[0086] <Wire Cover>

[0087] A wire cover 70 is installed on the wire pressing part 57. The wire cover 70 prevents the wire 30 from falling off the wire pressing part 57. The wire cover 70 and the wire pressing part 57 cover the entire circumference of the wire 30. In this embodiment, two wire covers 70 are provided. One of the two wire covers 70 presses two power lines 32. The other of the two wire covers 70 presses a grounding wire 36.

[0088] <Cover Unit>

[0089] The cover unit 80 is closably mounted on the end side of the cylindrical frame portion 52. Opening the cover unit 80 exposes the connection port of the housing body 51. An external charging connector is then inserted into the cylindrical frame portion 52, and the charging connector 10 and the external charging connector can connect. After charging, the external charging connector is removed from the cylindrical frame portion 52, and the cover unit 80 is closed, thereby locking the connection port of the housing body 51. The cover unit 80 includes a cover 82, a hinge unit 84, and a locking unit 86. The cover 82 is closably mounted on the housing body 51 via the hinge unit 84. The locking unit 86 holds the cover 82 in a closed state. During charging operations, the operator can operate the locking unit 86 to open the cover 82.

[0090] <Wire Protector>

[0091] The cable sheath 90 covers the housing 50 and the retainer 60. The cable sheath 90 includes a first protective part 91 and a second protective part 94. The first protective part 91 covers the rear end of the housing body 51 and the retainer 60. The second protective part 94 covers the wire pressing part 57. The cable sheath 90 is, for example, made of an elastic material such as EPDM.

[0092] A housing outlet 92 and a drain outlet 93 are formed in the first protective section 91. The front end of the housing body 51 extends outwards towards the cable protector 90 through the housing outlet 92. The drain outlet 93 is an opening for draining water that has entered the charging connector 10 to the outside. It is conceivable that water might enter through the opening of the housing body 51, for example, when the cover unit 80 is opened. A cable tie 98 is attached to the outer surface of the housing outlet 92. The cable protector 90 is attached to the housing 50 using the cable tie 98.

[0093] A wire outlet 95 is formed in the second protective section 94. The other end of the wire 30 extends outward from the sheath 90 through the wire outlet 95. Three wire outlets 95 are provided in one sheath 90. Two of the three wire outlets 95 are configured as two power lines 32. One power line 32 passes through each of the two wire outlets 95. The remaining wire outlet 95 contains a signal line 34, a grounding wire 36, and a thermistor wire 44.

[0094] <Wire path in the charging connector>

[0095] The power line 32 extends in a straight line from one end connected to the relay terminal 28 toward the other end within the sheath 90, and extends outward through the outlet to the outside of the sheath 90. Therefore, one end of the power line 32 is not inserted into the through hole.

[0096] Two power lines 32 extend within the sheath 90, arranged in the Z direction. Two power terminals 22 are housed in the housing body 51, arranged in the Y direction. The difference in the orientation of the two power lines 32 and the two power terminals 22 is absorbed by the relay terminal 28. More specifically, the two relay terminals 28 are respectively disposed on the plate. Relay terminal 28A of the two relay terminals 28 is connected to the power terminal 22 closer to the outlet, and relay terminal 28B is connected to the power terminal 22 farther from the outlet. Relay terminals 28A and 28B are arranged in the Y direction at the portions connected to the power terminals 22 and in the Z direction at the portions connected to the wires 30. Relay terminal 28A extends in a straight line along the plate between the portions connected to the power terminals 22 and the portions connected to the power lines 32. Relay terminal 28B bends away from the plate midway from the portion connected to the power terminals 22 toward the portion connected to the power lines 32.

[0097] One end of the signal wire 34 is inserted into the cavity. The other end of the signal wire 34 extends from the through hole, bending within the sheath 90 while heading towards the outlet of the sheath 90. Signal wire 34A of the plurality of signal wires 34 is connected to the signal terminal 24 located above the power terminal 22, and signal wire 34B is connected to the signal terminal 24 located below the power terminal 22. After extending from the through hole, signal wire 34A passes between a pair of power wires 32, merging with signal wire 34B and extending in the Y direction.

[0098] One end of the grounding wire 36 is inserted into the cavity. The grounding wire 36 extends from one end to the other through the through hole, bending within the sheath 90 while moving towards the outlet of the sheath 90 together with the signal wire 34. As described above, the grounding wire 36 is more difficult to bend than the signal wire 34; therefore, in the portion where the signal wire 34 and the grounding wire 36 bend from the X direction to the Y direction, the radius of curvature of the grounding wire 36 is more likely to become larger than that of the signal wire 34. By pressing the other end of the grounding wire 36 using the wire pressing portion 30 and the wire cover 70, excessive bulging of the grounding wire 36 within the sheath 90 is prevented.

[0099] The thermistor 42 is housed together with the power terminal 22 in the housing body 51. Therefore, one end of the thermistor wire 44 is also housed in the housing body 51. The other end of the thermistor wire 44 extends outward through a through-hole towards the outside of the plate, bending within the cable sheath 90 while facing the outlet of the cable sheath 90. The thermistor wire 44 passes through the portion in the through-hole for insertion of the terminald wire 38. The thermistor wire 44 extends in the Y direction together with the signal line 34 while passing between a pair of power lines 32.

[0100] <Lid and hinge unit>

[0101] Further reference Figures 8 to 10 The cover 82 and the hinge unit 84 are described. Figure 8 This is a diagram showing the cover 82 and the hinge unit 84. Figure 8 This is a view from the inner surface of cover 82. Figure 9 This is a diagram showing cover 82 in the closed state. Figure 10 This is a diagram showing the cover 82 in the open state. Figure 9 and Figure 10 The cross section shown is equivalent to along Figure 4 The cross section of the XI-XI line.

[0102] The cover 82 is closable and can be installed on the end side of the cylindrical frame portion 52. The cover 82 has a supported portion 82a, a locking portion 82b, and a cover body 83. The supported portion 82a is the part installed on the housing 50. The locking portion 82b is the part locked by the locking unit 86. The cover body 83 is the part that covers the end face of the cylindrical frame portion 52. The supported portion 82a and the locking portion 82b protrude outwards from the cover body 83. The supported portion 82a and the locking portion 82b extend in opposite directions from the outer edge of the cover body 83. For example, the cover 82 is a molded integral product made of resin material. The resin material of the cover 82 may, for example, be the same material as the resin material of the housing 50.

[0103] A sealing member 89 is provided on the inner surface 83a of the cover body 83. When the cover 82 is in the closed state, the sealing member 89 contacts the end face of the cylindrical frame portion 52. The sealing member 89 is a component formed independently of the cover 82. The sealing member 89 has higher elasticity than the cover 82 and the housing 50. The sealing member 89 can also be an elastic material, for example. When the cover 82 is in the closed state, the sealing member 89 is compressed by being sandwiched between the inner surface 83a of the cover body 83 and the end face of the cylindrical frame portion 52. This improves the sealing performance of the gap between the inner surface 83a of the cover body 83 and the end face of the cylindrical frame portion 52.

[0104] The sealing member 89 is formed in a ring shape. The sealing member 89 is shaped to correspond to the end face of the cylindrical frame portion 52. The sealing member 89 is mounted on the cover 82. This mounting method is not particularly limited and can be appropriately set. For example, the sealing member 89 can also be attached to the cover 82 using adhesive or double-sided tape.

[0105] The surface on the inner surface 83a of the cover body 83 that mounts the sealing member 89 is formed as a mounting surface 83b. An outer frame portion 83c is provided on the outer side of the mounting surface 83b in the inner surface 83a of the cover body 83. The outer frame portion 83c extends along the outer edge of the sealing member 89. Thus, the position of the outer edge of the sealing member 89 is restricted. The outer frame portion 83c is interrupted by the support portion 82a and the locking portion 82b.

[0106] A first rib 83d is provided on the inner surface 83a of the cover body 83, inside the mounting surface 83b. The first rib 83d is formed in a ring shape. The first rib 83d extends along the inner side of the sealing member 89. In the inner surface 83a of the cover body 83, the mounting surface 83b forms the bottom of a recess surrounded by the outer frame portion 83c and the first rib 83d. The first rib 83d is formed in a shape corresponding to the inner edge of the sealing member 89. The first rib 83d may also be formed to be the same as or slightly smaller than the inner edge of the sealing member 89. The end face of the cylindrical frame portion 52, the sealing member 89, and the first rib 83d each have an arc portion larger than a semicircle and a straight portion connecting the arc portions. A second rib 83e and a third rib 83f are provided on the inner side of the first rib 83d.

[0107] The second rib 83e extends radially from the center of the cover 82 toward the first rib 83d. Multiple second ribs 83e are provided (in... Figure 8 (Eight are shown in the example shown). Multiple second ribs 83e can also be arranged at equal intervals around the central part.

[0108] The third rib 83f is formed as a ring smaller than the first rib 83d. The third rib 83f can also be circular. Multiple second ribs 83e extend from the third rib 83f toward the first rib 83d. One end of the second rib 83e does not extend to the center of the cover 82 closer than the third rib 83f. One end of the second rib 83e terminates at the third rib 83f. The second rib 83e connects the first rib 83d and the third rib 83f. The other end of the second rib 83e does not extend to the outside of the cover 82 closer than the first rib 83d. The other end of the second rib 83e terminates at the first rib 83d.

[0109] The size (diameter) of the third rib 83f can also be such that one end of the plurality of second ribs 83e can be separated from each other. Adjacent second ribs 83e do not intersect each other and are connected via the third rib 83f. Thus, it is possible to prevent one end of the plurality of second ribs 83e from converging at a single point in the central part of the cover 82 (the center of the cover 82). The diameter of the third rib 83f can also be shorter than the length of the second ribs 83e.

[0110] like Figure 9 As shown, the outer surface 82c of the locking portion 82b is lower than the outer surface 83g of the cover body 83 towards the cylindrical frame portion 52. As a result, the protruding dimension of the locking unit 86 measured from the end face of the cylindrical frame portion 52 is reduced, which can reduce the gap between the panel 102 and the vehicle body side cover 106.

[0111] In addition, a guide portion 82d is provided in the locked portion 82b. The guide portion 82d is an inclined surface that slopes outward from the lower surface (the surface on the side of the cylindrical frame portion 52) of the locked portion 82b toward the upper surface.

[0112] The hinge unit 84 has a shaft portion 84a and a spring-loaded member 84b. The shaft portion 84a is an example of a cover-side shaft portion. The shaft portion 84a extends through the supported portion 82a. The spring-loaded member 84b is supported on the shaft portion 84a. The cover 82 is mounted to the cover mounting portion 58 of the housing 50 via the hinge unit 84. The cover mounting portion 58 has a pair of bearing portions. One end of the shaft portion 84a is supported on one of the pair of bearing portions, and the other end of the shaft portion 84a is supported on the other of the pair of bearing portions. The supported portion 82a and the spring-loaded member 84b are housed between the pair of bearing portions.

[0113] The cover 82 is rotatably mounted to the housing 50 via a shaft 84a. Alternatively, in this example, the shaft 84a is pressed into the cover mounting portion 58 and supported without rotation, while the cover 82 and the shaft 84a can rotate. Alternatively, the cover 82 and the shaft 84a can be pressed in and supported without rotation, while the shaft 84a can also be rotatably supported on the cover mounting portion 58.

[0114] The spring-loaded member 84b is an example of a cover-side spring-loaded member. The spring-loaded member 84b springs the cover 82 towards the open position along the rotational direction. The spring-loaded member 84b can also be an elastic member such as a spring. Figure 8 In the example shown, a torsion spring is used as the spring-loaded member 84b. Alternatively, when the cover 82 is opened to the point where the external charging connector can engage with the housing 50, a limiting portion can be used to restrict the cover 82 from opening further. For example, a limiting portion that contacts the outer peripheral surface of the cylindrical frame portion 52 can be provided in the supported portion 82a to restrict the opening of the cover 82.

[0115] Additionally, the cover 82 is mounted to the cover mounting portion 58 of the housing 50 via a damper 85. The damper 85 restricts the opening tendency of the cover 82 caused by the spring-loaded member 84b. The damper 85 is housed in the supported portion 82a. A damper housing portion is provided in the supported portion 82a. The supported portion 82a has a pair of bearing portions. A damper housing portion is provided on one of the pair of bearing portions in the supported portion 82a. The shaft portion 84a passes through the damper 85. The damper housing portion is provided next to the spring-loaded member 84b along the extending direction of the shaft portion 84a.

[0116] <Locking Unit>

[0117] Further reference Figure 11 and Figure 12 The locking unit 86 will be described. Figure 11 This is a perspective view showing the locking unit 86. Figure 12 yes Figure 4 A magnified view of region XII.

[0118] The locking unit 86 has a locking member 87 and a hinge unit 88. The locking member 87 locks into the cover 82. The locking member 87 is rotatably mounted to the housing 50 by means of the hinge unit 88. The locking member 87 has a supported portion 87a, a locking portion 87b, and a protrusion 87c.

[0119] The supported portion 87a is mounted on the housing 50. The supported portion 87a is supported by a shaft portion 88a in the hinge unit 88. The supported portion 87a has a pair of bearing portions. The shaft portion 88a in the hinge unit 88 passes through each bearing portion. The locking member 87 is rotatably supported on the cylindrical frame portion 52 by means of the shaft portion 88a between a first position and a second position. Figure 9 In the middle, the locking component 87 is located in the first position. Figure 10 In the middle, the locking component 87 is located in the second position.

[0120] The locking portion 87b protrudes radially outward from the supported portion 87a. For example... Figure 9 As shown, when the locking member 87 is in the first position, the locking part 87b can lock against the locked part 82b of the closed cover 82. Figure 10 As shown, the locking member 87 rotates from the first position to the second position, and the locking state of the locking part 87b and the locked part 82b of the cover 82 is released.

[0121] The locking portion 87b has a first portion that protrudes radially outward from the supported portion 87a, and a second portion that protrudes from the end of the first portion in a direction intersecting the extending direction of the first portion. The surface of the second portion facing the shaft portion presses against the top of the locking portion 82b.

[0122] A guide portion 87e and a protrusion 87f are provided on the top surface 87d of the locking portion 87b. The guide portion 87e is an inclined surface that slopes outward from the top surface 87d toward the lower surface.

[0123] The protrusion 87f extends along the extending direction of the shaft portion 88a. In this example, only one protrusion 87f is provided. The protrusion 87f is provided at the end of the top surface 87d on the side away from the cover 82. A portion of the first part of the locking portion 87b of the protrusion 87f extends in the extending direction.

[0124] The protrusion 87c is the portion that presses the cover 82 when it is bonded to the housing 50. The protrusion 87c protrudes radially outward from the supported portion 87a. Radially in the cylindrical frame portion 52, the protrusion 87c protrudes further into the cylindrical frame portion 52 than the locking portion 87b. (As...) Figure 9 As shown, when the locking member 87 is in the first position, the protrusion 87c is located along the X direction inside the end of the cylindrical frame portion 52. Figure 10 As shown, the locking member 87 rotates from the first position to the second position, and the protrusion 87c is located on the outer side of the end of the cylindrical frame portion 52 along the X direction.

[0125] The protrusion 87c can also be configured to contact the locked portion 82b after the locking portion 87b has disengaged from the locked portion 82b. For example, the position where the locking portion 87b has just disengaged from the locked portion 82b can be defined as the third position of the locking member 87. The third position is located between the first position and the second position, and the locking member 87 can rotate further from the third position toward the second position. The protrusion 87c can also be configured to contact the locked portion 82b at the third position. The protrusion 87c can also be configured to contact the locked portion 82b between the third position and the second position.

[0126] The upper surface of the protrusion 87c is formed as the pressing surface of the pressing cover 82. The upper surface of the protrusion 87c can also be an inclined surface that slopes from the outside of the cylindrical frame portion 52 toward the cylindrical frame portion 52 when the locking member 87 is in the first position. This prevents the protrusion 87c from contacting the locked portion 82b when the locking portion 87b is locked to the locked portion 82b. A pressing protrusion 87g is provided in the protrusion 87c. The pressing protrusion 87g is located in the central portion of the pressing surface of the protrusion 87c. The pressing protrusion 87g is thicker than other parts of the pressing surface and convexes outwards. This increases the rigidity of the protrusion 87c.

[0127] The protrusion 87c can also contact the guide portion 82d in the locked portion 82b on the side closer to the cover body 83. Thus, the force of the protrusion 87c pressing the locked portion 82b can easily act as a force to open the cover 82 bonded to the housing 50.

[0128] The locking member 87 further includes an isolating portion 87h. The isolating portion 87h protrudes from the outer surface of the supported portion 87a along the extending direction of the shaft portion 88a toward the bearing portion of the locking mounting portion 59. Around the isolating portion 87h, the outer surface of the supported portion 87a and the inner surface of the bearing portion of the locking mounting portion 59 are separated from each other and face each other. The isolating portion 87h reduces the contact area between the locking member 87 and the locking mounting portion 59. Furthermore, the inner surface of the bearing portion of the locking mounting portion 59 does not have a convex portion like the isolating portion 87h. A convex portion like the isolating portion 87h may also be provided on the inner surface of the bearing portion of the locking mounting portion 59.

[0129] The locking member 87 further includes a rotation limiting portion 87i. The rotation limiting portion 87i restricts the locking member 87 from further rotation in the rotation direction from the second position. The rotation limiting portion 87i protrudes radially outward from the supported portion 87a. The rotation limiting portion 87i protrudes inward from the protrusion portion 87c. In the second position, the rotation limiting portion 87i contacts the outer peripheral surface of the cylindrical frame portion 52, thereby restricting the locking member 87 from further rotation in the rotation direction from the second position.

[0130] The hinge unit 88 has a shaft portion 88a and a spring-loaded member 88b. The shaft portion 88a extends through the supported portion 87a. The spring-loaded member 88b is supported on the shaft portion 88a. The locking member 87 is mounted to the locking mounting portion 59 of the housing 50 via the hinge unit 88. The locking mounting portion 59 has a pair of bearing portions. One end of the shaft portion 88a is supported on one of the pair of bearing portions, and the other end of the shaft portion 88a is supported on the other of the pair of bearing portions. The supported portion 87a and the spring-loaded member 88b are housed between the pair of bearing portions of the locking mounting portion 59.

[0131] The locking member 87 is rotatably mounted to the housing 50 via the shaft portion 88a. Alternatively, in this example, the shaft portion 88a is pressed into the locking mounting portion 59 and supported so as not to rotate, while the locking member 87 and the shaft portion 88a can rotate. Alternatively, the locking member 87 and the shaft portion 88a can be pressed in and supported so as not to rotate, while the shaft portion 88a can also be rotatably supported on the locking mounting portion 59.

[0132] The spring-loaded member 88b is an example of a spring-loaded member on the locking member side. The spring-loaded member 88b presses the locking member 87 towards the first position along the rotational direction. The spring-loaded member 88b can also be an elastic member such as a spring. Figure 11In the example shown, a torsion spring is used as the spring-loaded member 88b. Furthermore, at least one of the locking portion 87b and the protrusion 87c can also restrict further rotation of the locking member 87 from the first position. For example, the locking member 87 can be restricted from further rotation from the first position by the locking portion 87b contacting the cover 82. Alternatively, the locking member 87 can be restricted from further rotation from the first position by the protrusion 87c contacting the outer peripheral surface of the cylindrical frame portion 52.

[0133] <Opening and closing operations>

[0134] Further reference Figure 13 The opening and closing operation of the cover unit 80 is explained. Figure 13 This diagram shows the locking member 87 in the middle position between the first and second positions.

[0135] <Open Operation>

[0136] First, the operation of opening cover 82, which is in the closed state, will be explained. The operator should be able to operate... Figure 9 The locking member 87 of the cover 82, which is in the closed state, is used to open the cover 82. At this time, as shown... Figure 13 As shown, the operator uses their fingers (WF, etc.) to operate the locking member 87 to rotate it from position 1 to position 2. When the cover 82 and the cylindrical frame portion 52 are not bonded, when the locking member 87 rotates and the locking portion 87b disengages from the locked portion 82b, the cover 82 is opened by the spring force of the spring-loaded member 84b.

[0137] If the cover 82 is bonded to the cylindrical frame portion 52, even if the locking member 87 rotates and causes the locking portion 87b to leave the locked portion 82b, the cover 82 can still remain closed against the spring pressure of the spring pressure member 84b, without any countermeasures.

[0138] In this disclosure, by providing the protrusion 87c, the cover 82 can be easily opened even if it is adhered to the cylindrical frame portion 52. That is, when the locking member 87 rotates to disengage the locking portion 87b from the locked portion 82b, as... Figure 13 As shown, the cover 82, bonded to the protrusion 87c, is pressed in the opening direction. Under this force F, the bond between the cover 82 and the cylindrical frame portion 52 is released, allowing the cover 82 to open. In this example, the spring-loaded member 84b applies a spring force to the cover 82 in the opening direction. Therefore, when the upward pushing action of the protrusion 87c on the cover 82 provides an opportunity to peel off the bonded portion between the cover 82 and the housing 50, the cover 82 can be transferred from the closed state to the open state via the spring-loaded member 84b.

[0139] Furthermore, in this example, an isolation portion 87h is provided, thus reducing the contact area between the locking member 87 and the locking mounting portion 59. Therefore, even if water freezes or causes the locking member 87 and the locking mounting portion 59 to stick together, the increase in the force required for the operator to operate the locking member 87 can be suppressed. As a result, it is easier for the operator to open the cover 82.

[0140] <Close Operation>

[0141] like Figure 10 The closing operation of the cover 82, which is shown in the open state, will be explained. Furthermore, in... Figure 10 In this example, the locking member 87 is in the second position. In this case, the spring-loaded member 88b applies a spring force to the locking member 87 towards the first position. When the operator's finger WF leaves the locking member 87, the locking member 87 rotates due to the spring force of the spring-loaded member 88b. Even when the cover 82 is open, the locking member 87 remains in the first position when the operator's finger WF leaves the locking member 87.

[0142] When the cover 82 is closed from its open position, if the locking member 87 is in the first position, the locking part 87b is located on the track of the locked part 82b. Therefore, during the closing process of the cover 82, the locking part 87b interferes with the locked part 82b. At this time, a force conversion part is provided to convert the force of the interference between the cover 82 and the locking member 87 into a force that rotates the locking member 87 to the second position. As such a force conversion part, the aforementioned guide part 82d is provided in the locked part 82b, and the aforementioned guide part 87e is provided in the locking part 87b.

[0143] When the cover 82 is further closed with the two guide portions 82d and 87e in contact, guide portion 82d presses against guide portion 87e. Because the surface of guide portion 87e in contact with guide portion 82d becomes an inclined surface, the force on guide portion 87e from guide portion 82d is transformed into a force that causes the locking member 87 to rotate toward the second position. As a result, the locking member 87 rotates toward the second position, and the locked portion 82b can pass through the locking portion 87b.

[0144] When the locked part 82b passes the locked part 87b, the cover 82 is in the closed position. Furthermore, the contact between the two guide parts 82d and 87e is released, and the locking member 87 rotates due to the spring force of the spring-loaded member 88b, reaching the first position. Thus, the locked part 87b is locked to the locked part 82b.

[0145] <Effects, etc.>

[0146] According to the charging connector 10 configured as described above, when the locking member 87 rotates from the first position to the second position, the protrusion 87c is positioned to push the cover 82 upwards. Therefore, even if the cover 82 and the housing 50 are stuck together when frozen, the cover 82 can be easily opened. In addition, the protrusion 87c transforms the action of pushing the cover 82 upwards into the action of rotating the locking member 87 from the first position to the second position, thus suppressing the increase of operator movements.

[0147] Furthermore, the locking member 87 further has a protrusion 87f, which is formed on the top surface 87d of the locking portion 87b and extends along the extending direction of the shaft portion 88a. Thus, when the operator operates the locking member 87, the protrusion 87f becomes a hook and is difficult to slide, making the operation of the locking member 87 easier.

[0148] Furthermore, the protrusion 87f is provided at the end of the top surface 87d on the side away from the cover 82. As a result, when the operator moves the locking member 87 from the first position to the second position, the protrusion 87f can easily become a hook.

[0149] Furthermore, an annular first rib 83d extending along the inner side of the sealing member 89 is formed on the inner surface 83a of the cover 82. Thus, when the sealing member 89 is provided in the cover 82 as a separate component from the cover 82, the first rib 83d can be used for positioning.

[0150] Furthermore, a plurality of second ribs 83e are formed on the inner surface 83a of the cover 82, extending radially from the center of the cover 82 toward the first rib 83d. As a result, the rigidity of the cover 82 is improved.

[0151] Furthermore, on the inner surface 83a of the cover 82, an annular third rib 83f is formed inside the first rib 83d, and multiple second ribs 83e extend towards the first rib 83d from the third rib 83f. This prevents the multiple second ribs 83e from intersecting at the central portion, improving the formability of the cover 82. More specifically, when the cover 82 is integrally formed by a mold, if multiple second ribs 83e are concentrated at a single point in the center of the cover 82, the concentrated area becomes thicker, making it prone to pores, cracks, etc. In contrast, in this example, the intersection of multiple second ribs 83e at the central portion is prevented, thus making it difficult to produce locally thickened areas, and thus less likely to produce pores, cracks, etc. Additionally, when multiple second ribs 83e are concentrated at a single point in the center of the cover 82, the intersection of the second ribs 83e in the mold becomes an acute angle, potentially reducing the durability of the mold. In contrast, in this example, because one end of each of the multiple second ribs 83e is separated, it is difficult to produce sharp angles, which can suppress the reduction of mold durability.

[0152] In addition, by setting the first rib 83d, the second rib 83e and the third rib 83f respectively, the warping and other deformations of the cover body 83 can be suppressed even when the cover body 83 is relatively thin.

[0153] Furthermore, around the isolation portion 87h, the outer surface of the supported portion 87a and the inner surface of the bearing portion of the locking mounting portion 59 are separated from each other and face each other. As a result, the contact area between the locking member 87 and the locking mounting portion 59 is reduced, and even if the locking member 87 and the locking mounting portion 59 stick together due to freezing or the like, it can be prevented from becoming a problem for the operator to operate the locking member 87.

[0154] Furthermore, the outer surface 82c of the locking portion 82b is lower towards the cylindrical frame portion 52 than the outer surface 83g of the cover body 83. As a result, the protruding dimension of the locking portion 87b in the outward direction of the vehicle becomes smaller.

[0155] Furthermore, the charging connector 10 further includes a spring-loaded member 88b that springs the locking member 87 toward the first position along the rotation direction. Thus, the protrusion 87c transforms the pushing action of the cover 82 upward into the action of the operator resisting the spring-loaded member 88b, causing the locking member 87 to rotate from the first position toward the second position.

[0156] Furthermore, the charging connector 10 further includes a spring-loaded member 84b that springs the cover 82 toward the open state along the rotation direction. Thus, when the upward pushing action of the protrusion 87c on the cover 82 provides an opportunity to peel off the adhesive portion between the cover 82 and the housing 50, the cover 82 can be transferred from the closed state to the open state by means of the spring-loaded member 84b.

[0157] [Postscript]

[0158] Figure 14 This is a rear view showing a modified example of the charging connector 110. Furthermore, in Figure 14 In this variation, some components, such as signal line 34, are omitted. Furthermore, in the description of this variation, structural elements identical to those in the previously described structure are labeled with the same reference numerals, and their descriptions are omitted.

[0159] exist Figure 14 The charging connector 110 shown has eight signal terminals 24. Additionally, in this example, the ground terminal 26 is omitted. Consequently, the structure of the ground terminal 26 is omitted in the housing 150 and the retainer 160. The aforementioned cover unit 80 can also be used in this charging connector 110.

[0160] Figure 15 This is a perspective view showing a modified example of the mounting method of the housing 50 and the cover unit 80. Figure 16 It is along Figure 15 A cross-sectional view along the XVI-XVI line. Figure 17Is with Figure 16 The sectional view at the same location shows the lid 82 in the closed state.

[0161] In this modified example, the spring-loaded member 84b, serving as the cover-side spring-loaded member, includes a spring body portion 84c and a spring arm portion 84d extending from the spring body portion 84c. An interference portion 82f is provided on at least one of the cover 82 and the housing 50. This interference portion 82f interferes with the spring arm portion 84d when the installation posture of the spring-loaded member 84b is different from the normal posture. Therefore, it is possible to prevent the spring-loaded member 84b from being installed in a posture different from the normal posture.

[0162] Specifically, the spring-loaded member 84b is a torsion spring, and the spring body 84c is a coil spring. Here, the spring-loaded member 84b presses the cover 82 into the open state. Therefore, the state of the spring body 84c when the cover 82 is open is closer to its natural state than the state of the spring body 84c when the cover 82 is closed.

[0163] A pair of spring arms 84d are provided. The pair of spring arms 84d extend from one end and the other end of the spring body 84c, respectively. Each spring arm 84d includes a first extension portion 84e extending from the end of the spring body 84c and a second extension portion 84f extending from the end of the first extension portion 84e in a direction intersecting the first extension portion 84e. Here, the first extension portion 84e extends from the end of the spring body 84c in a tangential direction to the coil spring at that end. Here, the second extension portion 84f extends in the axial direction of the spring body 84c.

[0164] One of the pair of spring arms 84d, spring arm 84d1, is supported on the spring support surface 58a of the housing 50. In spring arm 84d1, a second extension 84f is supported on the spring support surface 58a. The other of the pair of spring arms 84d, spring arm 84d2, is supported on the spring support surface 82e of the cover 82. In spring arm 84d2, a second extension 84f is supported on the spring support surface 82e.

[0165] Here, the pair of spring arms 84d are formed in a symmetrical shape, and the spring-loaded member 84b has the same shape when viewed from one side along the axial direction of the spring body 84c and from the other side. That is, the first extension portion 84e of spring arm 84d1 and the first extension portion 84e of spring arm 84d2 have the same length. In addition, the second extension portion 84f of spring arm 84d1 and the second extension portion 84f of spring arm 84d2 have the same length. Furthermore, the second extension portions 84f of spring arm 84d1 and the second extension portions 84f of spring arm 84d2 extend in a direction that approaches each other or in a direction that moves away from each other (in this case, the direction that approaches each other). The aforementioned shaft portion 84a is inserted into the spring body 84c. It is also possible that either one end or the other end of the spring-loaded member 84b along the axial direction is located at one end of the shaft portion 84a. In other words, the insertion direction of the shaft portion 84a relative to the spring body portion 84c is arbitrary, and the spring-loaded member 84b can achieve a proper posture even if either of the pair of spring arms 84d is located at one end of the shaft portion 84a.

[0166] The spring arm 84d is the part subjected to the external force applied by the opening and closing operation of the cover 82. The external force on the spring arm 84d is transmitted to the spring body 84c, changing the elastic deformation state of the spring body 84c. Here, the normal posture of the spring-loaded member 84b is set to... Figure 16 The installation posture is subject to external force in the direction of arrow F1. In the spring compression member 84b, which is a torsion spring, when the cover 82 is opened and closed, the direction in which the pair of spring arms 84d are operated is the direction F1 around the axis, which is the normal posture, and when it is the other direction F2, it is a posture different from the normal posture.

[0167] The operator closes the open cover 82 by pressing it. The force applied by this operation acts from the spring support surface 82e of the cover 82 in the direction of arrow F1 onto the spring-loaded member 84b, deforming the spring body 84c. When the cover 82 reaches the closed position, the locking member 87 of the locking unit 86 rotates to the locked position, thus locking the cover 82. Therefore, even if the spring-loaded member 84b presses the cover 82 to elastically recover, movement of the cover 82 is suppressed, and the spring body 84c remains in a deformed state when the cover 82 is closed.

[0168] The operator's action of opening the closed cover 82 is an operation to release the locking unit 86. The force applied in this operation is not transmitted to the spring-loaded member 84b. The cover 82 is released from its lock by rotating the locking member 87 of the locking unit 86 to the retracted position, thus preventing the cover 82 from supporting the force applied by the elastic recovery of the spring-loaded member 84b. As a result, the spring-loaded member 84b elastically recovers, and the cover 82 opens.

[0169] Here, the installation posture of the interference part 82f suppressing the elastic compression member 84b changes to... Figure 16 The direction of arrow F2 is subject to an external force. Regarding the installation posture of the spring-loaded member 84b, it becomes... Figure 16 The orientation of the arrow F2 under the influence of an external force, except for... Figures 15 to 17 In addition, refer to Figure 18 Please provide an explanation. Figure 18 This diagram shows the case where the installation posture of the spring-loaded member 84b is reversed.

[0170] The installation posture of the spring-loaded component 84b becomes... Figure 16 When subjected to an external force in the direction of arrow F2, the spring-loaded member 84b changes to a position where it has rotated 180 degrees around its axis from its normal position. In this mounting position, the opposing forces supported by the pair of spring arms 84d are opposite to those supported by the pair of spring arms 84d in the normal position. That is, of the pair of spring arms 84d1 and 84d2, the spring arm 84d1 located at one end of the axis 84a is supported by the cover 82, and the spring arm 84d2 located at the other end of the axis 84a is supported by the housing 50.

[0171] Here, an interference portion 82f is provided on the cover 82. The interference portion 82f is provided at a position that contacts the first extension portion 84e of the spring arm portion 84d1 located at one end of the shaft portion 84a in a pair of spring arm portions 84d1, 84d2. The interference portion 82f is a rib that protrudes from the spring support surface 82e of the cover 82 toward the spring support surface 58a of the housing 50 from the side of the spring support surface 82e toward the shaft portion 84a. Figure 18 The line L is a tangent L through the shaft portion 84a of the spring support surface 82e. For example, the interference portion 82f protrudes beyond this tangent L.

[0172] An interference portion 82f is partially provided at one end along the axial direction of the shaft portion 84a. No interference portion 82f is provided at the other end of the shaft portion 84a along the axial direction. Therefore, when the spring-loaded member 84b is in its normal mounting position, the interference portion 82f does not contact the first extension portion 84e of the spring arm portion 84d2 located at the other end of the shaft portion 84a. Furthermore, the protrusion amount of the interference portion 82f can also be set as follows: Figure 17 As shown, when the spring-loaded member 84b is installed in the correct position and the cover 82 is in the closed state, it does not contact the spring arm portion 84d1 at one end of the shaft portion 84a. The supported portion 82a has a through portion 82g through which the shaft portion 84a passes. An interference portion 82f is provided at the intersection of the through portion 82g and the side portion including the support surface 82e.

[0173] like Figure 18As shown by the imaginary line, when the spring-loaded member 84b is installed in the opposite direction to the normal position, the spring arm 84d1 comes into contact with the interference part 82f. Therefore, the operator can easily notice errors in the installation posture of the spring-loaded member 84b and can prevent the spring-loaded member 84b from being installed in a posture different from the normal position.

[0174] Furthermore, Figure 18 The opening angle of the cover shown is the same as the opening angle when the cover is fully open when the spring-loaded member 84b is in its normal position. Additionally, Figure 18 The imaginary line shows the spring-loaded member 84b under the force in the direction of arrow F2. The spring-loaded member 84b is temporarily installed... Figure 18 In the state shown by the imaginary line, the spring arm 84d1 contacts the end edge of the interference part 82f. Therefore, the interference part 82f cannot support the force of the elastic member 84b to elastically recover, and the elastic member 84b presses down on the cover 82. As a result, the cover rotates in the closing direction until the spring arm 84d contacts the support surface of the cover, and the opening angle of the cover is less than... Figure 18 The angle shown is the opening angle of the correct posture. As a result, the operator can easily notice errors in the installation posture of the spring-loaded member 84b and prevent the spring-loaded member 84b from being installed in a posture different from the correct posture.

[0175] Furthermore, the interference portion 82f is provided on the cover 82 in a protruding form, so even if water or other substances freeze and ice forms around the cover mounting portion 58, the protruding interference portion 82f can break up the ice during the opening and closing operation of the cover 82. As a result, the cover unit 80 can be opened easily even when frozen.

[0176] Furthermore, it was previously described that the locking member 87 had a protrusion 87f on the top surface 87d of the locking portion 87b, but this is not a necessary structure. For example, the protrusion 87f may not be provided. Moreover, even if the protrusion 87f is not provided, the structure is not limited to the structure described above. For example, the protrusion 87f may be provided in the middle of the top surface 87d and next to the guide portion 87e. Additionally, for example, the protrusion 87f may not be a single protrusion, but multiple protrusions may be provided. In this case, the height of the top surface 87d can be increased in stages in the direction away from the cylindrical frame portion 52 by using multiple protrusions.

[0177] Furthermore, it was previously described that a first rib 83d, a second rib 83e, and a third rib 83f were formed on the inner surface 83a of the cover 82, but this is not a necessary structure. Any or all of the first rib 83d, the second rib 83e, and the third rib 83f may be omitted.

[0178] Furthermore, while the locking member 87 was previously described assuming it had an isolation portion 87h, this is not a necessary structure. For example, the isolation portion 87h can be omitted. In this case, the outer surface of the supported portion 87a can also be a flat surface. Alternatively, for example, the portion corresponding to the isolation portion 87h can also be provided on the locking mounting portion 59 side.

[0179] Furthermore, it was previously described that the outer surface 82c of the locking portion 82b is lower than the outer surface 83g of the cover body 83 towards the cylindrical frame portion 52, but this is not a necessary structure. For example, the outer surface 82c of the locking portion 82b may also be flush with the outer surface 83g of the cover body 83 or higher towards the outside of the vehicle.

[0180] Furthermore, the previous description assumed that the charging connector 10 had a spring-loaded member 88b, which serves as a locking member-side spring-loaded member, but this is not a necessary structure. For example, the charging connector 10 may not have a locking member-side spring-loaded member.

[0181] Furthermore, the previous description assumed that the charging connector 10 had a spring-loaded member 84b as a cover-side spring-loaded member, but this is not a necessary structure. For example, the charging connector 10 may not have a cover-side spring-loaded member.

[0182] Furthermore, the structures described in the above embodiments and variations can be appropriately combined as long as they do not contradict each other.
