[0023] [Description of embodiments of this disclosure]

[0024] First, the implementation methods of this disclosure are listed and explained.

[0025] The charging connector disclosed herein is as follows.

[0026] (1) A charging connector mounted on a vehicle, an external charging connector connected to an external power source of the vehicle, is plugged in and out relative to the charging connector, the charging connector being used to charge a battery provided by the vehicle, and comprising: a plurality of first terminals; second terminals thicker than the first terminals; a housing body having an opening for plugging in and out of the external charging connector and a plurality of terminal receiving portions, the plurality of terminal receiving portions being located inside the opening when viewed from the plugging / unplugging direction of the external charging connector, and receiving the plurality of first terminals and the second terminals; a stop body, fitted at an end opposite to the opening relative to the terminal receiving portions, holding the first terminals and the second terminals together with the housing body; a plurality of first terminals... A wire, electrically connected to each of the plurality of first terminals; a second wire, electrically connected to the second terminal, and thicker than the first wire; a wire retainer, which, when viewed along the insertion / removal direction away from the second terminal, retains a portion of the length direction of the second wire in a direction intersecting the length direction of the second terminal; and an outer fitting member that covers the first terminal, the second terminal, the stop, and the wire retainer from the side opposite to the opening, wherein the second wire has a bend located between the second terminal and the wire retainer, and bends from the length direction of the second terminal in a direction intersecting the length direction of the second terminal.

[0027] According to this disclosure, the second wire is held in a bent state by the wire holding part. This avoids interference between the second wire and the outer component, and allows the second wire to be routed within the outer component. Therefore, for example, the assembly of outer components such as cable sheaths can be easily performed. Furthermore, because the wire holding part holds the second wire at a position far from the second terminal, the configuration is simplified compared to a configuration that holds the entire bent portion.

[0028] (2) Alternatively, a guide portion for guiding at least one of the first wires may be provided in the wire holding portion at a position separated from the second wire by the partition wall. According to this disclosure, the first wire is also guided by the guide portion provided in the wire holding portion, thus concentrating and simplifying the laying path of the first wire within the vehicle. Because the second wire is held in a state separated from the first wire by the partition wall, the wire holding portion can securely hold the second wire in a certain position.

[0029] (3) Alternatively, the guide portion may have a retaining groove that opens in a direction intersecting the length direction of the first wire and extends along the length direction of the first wire. According to this disclosure, the first wire can be easily positioned toward the guide portion.

[0030] (4) Alternatively, an arm extending along the second wire can be integrally formed on the housing body, and the wire holding portion can be integrally formed with the arm. A cover member is further provided, which is detachably mounted to the wire holding portion to cover the second wire held therein. According to this disclosure, because the wire holding portion is provided on the arm of the housing, the wire holding portion can be moved away from the second terminal. Furthermore, by mounting the cover member to the wire holding portion, detachment of the second wire can be prevented.

[0031] (5) The outer casing may also be flexible. According to this disclosure, because the cable sheath is flexible, it can be easily installed. In addition, even when the bent portion of the second wire abuts against the cable sheath, the bent portion of the second wire can be gently pressed.

[0032] (6) The outer component has an outlet for leading the plurality of first wires and the second wires outward together, the wire holding portion guides the second wires toward the outlet, and the guiding portion guides the first wires toward the outlet. According to this disclosure, the configuration for holding the first wires and the second wires can be simplified.

[0033] (7) It may further include: a power terminal connected to a terminal in the external charging connector that supplies power to the battery; a relay terminal fitted to the end of the power terminal on the side opposite to the opening, extending in a direction intersecting the length direction of the power terminal; and a power line electrically connected to the power terminal via the relay terminal, extending in a direction intersecting the length direction of the power terminal. According to this disclosure, because a relay terminal extending in a direction intersecting the length direction of the power terminal is provided, the power line can extend in a direction intersecting the length direction of the power terminal. Therefore, interference with other components inside the vehicle can be avoided.

[0034] [Details of the embodiments of this disclosure]

[0035] The following is a reference to the appendix. Figure 1 Specific examples of the charging connectors described herein are illustrated below. Furthermore, this disclosure is not limited to these examples, but is intended to include all modifications within the meaning and scope of the claims, as shown by the claims themselves.

[0036] In the accompanying drawings, for ease of explanation, some components are sometimes shown enlarged or simplified. Furthermore, the dimensional ratios of the various parts sometimes differ in the accompanying drawings. Additionally, 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 approximately parallel or orthogonal to the extent that they serve their function and effect in this embodiment.

[0037] [Implementation Method 1]

[0038] The charging connector 10 of Embodiment 1 will be described below. Figure 1 This is a schematic diagram showing a vehicle 1 equipped with a charging connector 10 together with an external power source 9.

[0039] <About Vehicle 1>

[0040] Vehicle 1 includes body 2, battery 3, PCU (Power Control Unit) 4, electric generator 5, charger 6, and charging connector 10.

[0041] Battery 3 is a rechargeable battery, such as a lithium-ion battery. PCU4 includes an inverter and converter. Electric generator 5 is a rotary electric machine that functions as both a drive motor and a generator. PCU4 converts the DC power supplied from battery 3 into AC power and supplies it to electric generator 5. Electric generator 5 is driven using the AC (or DC) power supplied from PCU4, driving the drive wheels. Additionally, electric generator 5 generates electricity when the wheels decelerate, etc. PCU4 converts the AC power generated by electric generator 5 into DC power to charge battery 3.

[0042] The body 2 is the part that constitutes the exterior of the vehicle 1. A cover is provided on the body 2. When the cover is opened, the charging connector 10 is exposed to the outside. The location of the charging connector 10 is arbitrary. For example, the charging connector 10 can be located at the front of the body 2 or at the rear of the side.

[0043] Charger 6 is connected to charging connector 10 and battery 3. Charger 6 can, for example, convert AC power supplied from charging connector 10 to DC power, or convert the DC power supplied from charging connector 10 to DC power and supply it to battery 3.

[0044] The charging methods for battery 3 in vehicle 1 generally include normal charging and fast charging. Fast charging achieves charging in a shorter time by using a larger current than normal charging. Normal charging assumes the use of household power or an equivalent external power source. Fast charging assumes the use of a dedicated power source, such as a charging station. The charging connector 10 disclosed herein will be described as a fast charging connector.

[0045] <Charging connector 10 in vehicle 1>

[0046] The charging connector 10 is used for charging the battery 3 of the vehicle 1. The charging connector 10 is mounted on the vehicle 1. An external charging connector 7, which is connected to an external power source 9 of the vehicle 1, can be plugged into the charging connector 10. Specifically, the charging connector 10 is connected to the terminals of the external charging connector 7 by engaging with it. In this embodiment, the pin-shaped terminals of the external charging connector 7 are engaged with the cylindrical terminals of the charging connector 10. Alternatively, the pin-shaped terminals of the charging connector 10 can also be engaged with the cylindrical terminals of the external charging connector 7. The external charging connector 7 is connected to the external power source 9 via a converter 8.

[0047] The converter 8 adjusts the current and voltage of the power supplied from the external power source 9 and supplies them to the battery 3. The vehicle 1 moves by using the power from the battery 3 to drive the motor. The vehicle 1 can be either an electric vehicle with only a motor as the drive source, or a hybrid vehicle with both a motor and an engine.

[0048] Figure 2 This is a top view showing the charging connector 10 of Embodiment 1 and its assembly method. The charging connector 10 is configured to connect to an external charging connector 7 (see reference 7). Figure 1 The charging connector 10 is fitted into the assembly part 100, which is located in the body 2 of the vehicle 1. Figure 2An example of the mounting portion 100 is shown. The mounting portion 100 is, for example, a part of the panel 102 constituting the vehicle body 2, formed as a recessed portion that is recessed inwards towards the vehicle. The opening of the recess of the panel 102 forms an opening that can receive an external charging connector. A through hole 104 is formed in the bottom of the panel 102 in the mounting portion 100.

[0049] A connection portion for connecting to the external charging connector 7 is provided on the outer side of the vehicle 1 in the insertion / removal direction of the external charging connector 7. The connection portion includes a section into which the external charging connector 7 is inserted and electrically connected. A portion of the charging connector 10, including the connection portion, passes through a through hole 104 and protrudes from the outer side of the panel 102. Another portion of the charging connector 10 is located on the inner side of the vehicle than the panel 102. Typically, a body side cover 106 is provided in the mounting section 100. The body side cover 106 is mounted to the panel 102 in an openable / closable manner using 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.

[0050] In this disclosure, such as Figure 2 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 7 are connected in the X direction. In this specification, the X direction is referred to as the insertion / removal direction of the external charging connector 7. The Y direction is the arrangement direction of a pair of power terminals. The Z direction is orthogonal to both the X and Y directions. For example, when the charging connector 10 is provided on the side of the vehicle 1, the X direction is the left-right direction of the vehicle, the Y direction is the front-rear direction of the vehicle, and the Z direction is the vertical direction. For example, when the charging connector 10 is provided on the front or rear surface of the vehicle 1, the X direction is the front-rear direction of the vehicle, the Y direction is the left-right direction of the vehicle, and the Z direction is the vertical direction.

[0051] <Regarding the overall composition>

[0052] remove Figure 2 In addition, they also referred to Figures 3 to 6 The overall structure of the charging connector 10 will be explained. Figure 3 This is a perspective view of the charging connector 10 of Embodiment 1 shown from the rear. Figure 4 This is an exploded perspective view showing the charging connector 10 of Embodiment 1. Figure 5 This is a front view showing the charging connector 10 of Embodiment 1. Figure 6 It is along Figure 5 A sectional view along line VI-VI. Additionally... Figure 7This is an explanatory diagram showing the housing 30 and the layout of each wire from the back. Furthermore, in Figure 4 The power line 41 is omitted in the text.

[0053] The charging connector 10 includes a housing 30, terminals 11 to 14, wires 41 to 43, cover members 15 and 16, a stop body 60, a cover unit 80, and a cable sleeve 90 as an external component.

[0054] <Regarding terminals 11-14>

[0055] like Figure 4 , Figure 5 as well as Figure 6 As shown, the terminals include, for example, a pair of power terminals 11, a signal terminal 12, a ground terminal 13, and a relay terminal 14. The power terminals 11, signal terminals 12, and ground terminal 13 are housed in the housing 30. During charging, the power terminals 11, signal terminals 12, and ground terminal 13 are connected to the terminals (not shown) of the external charging connector 7 described above. More specifically, the pair of power terminals 11 are connected to the terminals of the external charging connector 7 that supplies power to the battery 3 from the exterior of the vehicle 1. Additionally, the signal terminal 12 is connected to the terminals of the external charging connector 7 that transmits signals between the exterior of the vehicle 1 and the control unit (PCU4) of the vehicle 1.

[0056] like Figure 4 and Figure 5 As shown, the quantity and type of each terminal 11-14 are appropriately set according to the specifications of the charging connector 10. In this embodiment, a pair of power terminals 11, six signal terminals 12, and one ground terminal 13 are provided. The relay terminal 14 is clamped between the power terminal 11 and the power line 41 (see reference). Figure 5 The relay terminal 14 electrically connects the power supply terminal 11 and the power line 41. The relay terminal 14 has the same number as the power supply terminal 11 (two in this case). Each terminal 11 to 14 is formed, for example, by stamping (bending) a metal sheet.

[0057] <Regarding the various wires>

[0058] like Figure 6As shown, one end of each wire is electrically connected to terminals 11-14, for example. The other end of each wire extends outward from the cable sleeve 90. When the charging connector 10 is mounted in the vehicle, the other end of each wire is connected to another device mounted in the vehicle. Such a device is appropriately configured depending on the type of wire, and may include, for example, a battery, an electronic control unit (ECU), etc. The number and type of wires correspond to the number and type of terminals 11-14. In the example of this embodiment, each wire 40 includes two power lines 41, six signal lines 42, and one ground line 43. In addition, each wire also includes wires connected to sensors for measuring terminal temperature. One end of the power line 41 is connected to the relay terminal 14. The power line 41 is connected to the power terminal 11 via the relay terminal 14 (see reference). Figure 7 One end of signal line 42 is connected to signal terminal 12. One end of ground line 43 is connected to ground terminal 13. In this embodiment, signal terminal 12 is an example of a first terminal, and signal line 42 is an example of a first wire. Ground terminal 13 is an example of a second terminal that is thicker than signal terminal 12, and ground line 43 is an example of a second wire that is thicker than signal line 42.

[0059] Each wire is a sheathed wire. A sheathed wire has a core wire and a sheath covering the core wire. The core wire is formed, for example, by twisting together multiple metal wires. The sheath is formed, for example, by extruding an insulating resin around the core wire. Various wires of different thicknesses can be used as individual wires. The thickness of each wire is set according to factors such as allowable current value. Generally, to increase the allowable current value, the conductor cross-sectional area needs to be increased, and correspondingly, the wire thickness becomes thicker. Furthermore, the thickness of the wire is generally related to its bending difficulty; as the wire becomes thicker, it becomes more difficult to bend. For example, when bending an easily bendable wire and a difficult-to-bend wire by the same angle, the radius of curvature of the difficult-to-bend wire is larger than that of the easily bendable wire, and correspondingly, a larger arrangement space is required.

[0060] like Figure 7 As shown, in this example, the power line 41 is thicker than the signal line 42 and the ground line 43. Therefore, the power line 41 is more difficult to bend than the signal line 42 and the ground line 43. Furthermore, the ground line 43 is thicker than the signal line 42. Therefore, the ground line 43 is more difficult to bend than the signal line 42. Especially in recent years, due to the requirements of fast charging, large currents flow through the power line 41, so the diameter of the power line 41 is being increased. For example, a wire of 70 square millimeters to 95 square millimeters or larger is used for the power line 41. In addition, according to the recent requirements of fast charging, in order to allow for large currents, the diameter of the ground line 43 is also being increased. For example, a wire of 20 square millimeters or larger is used for the ground line 43. Furthermore, the grounding terminal 13 is thicker than the signal terminal 12.

[0061] <Regarding relay terminal 14 and power line 41>

[0062] like Figure 4 , Figure 6 as well as Figure 7 As shown, a pair of relay terminals 14 are fitted onto the end of each power terminal 11 on the side opposite to the connection side with the external charging connector 7 (that is, the end opposite to the opening 36A). Each relay terminal 14 extends, for example, in a direction orthogonal to the insertion / removal direction (X direction) of the external charging connector 7. Furthermore, as... Figures 7 to 9 As shown, a pair of power lines 41 are fixed to each relay terminal 14 in a direction orthogonal to the insertion / removal direction of the external charging connector 7. This configuration reduces the space required for the charging connector 10 in the insertion / removal direction (X direction) of the external charging connector 7. Furthermore, in this embodiment, each relay terminal 14 and the power lines 41 are configured to extend in a direction orthogonal to the insertion / removal direction (X direction) of the external charging connector 7, but this is not limited to an orthogonal direction; they can also extend in intersecting directions. However, from the viewpoint of saving space for the charging connector 10 in the insertion / removal direction (X direction) of the external charging connector 7, it is preferable to have a configuration extending in a direction orthogonal to the insertion / removal direction (X direction) of the external charging connector 7. Thus, because the relay terminal 14 extends in a direction intersecting the length direction (X direction) of the power terminal 11, the power lines 41 can extend in a direction intersecting the length direction (X direction) of the power terminal 11. Therefore, interference with other components within the vehicle 1 can be avoided.

[0063] Furthermore, the power line 41 is connected to the relay terminal 14 and extends linearly from the relay terminal 14 to the power line holding portion 37. When the power line 41 extends linearly in this way, the extension direction of the power line 41 can be restricted by the extension direction of the relay terminal 14. That is, the degree of freedom in the wiring direction of the power line 41 is increased by the relay terminal 14. The power line 41 extends further linearly from the power line holding portion 37 within the cable sleeve 90 and exits from the wire outlet 95 of the cable sleeve 90. By extending the power line 41 linearly within the cable sleeve 90, it is not necessary to provide space within the cable sleeve 90 to accommodate the bent power line 41, thus enabling miniaturization of the charging connector 10.

[0064] <About casing 30>

[0065] Figure 7 This is a rear view showing the housing 30 and the relay terminal 14. Figure 8 This is a side view showing the housing 30 and the relay terminal 14. Furthermore, in Figure 7 and Figure 8 In the diagram, each wire is represented by a virtual line.

[0066] like Figures 2-8 As shown, the housing 30 is formed, for example, using synthetic resin. The housing 30 includes a housing body 31 and a vehicle mounting portion 32. A pair of power terminal receiving portions 33, multiple signal terminal receiving portions 34, and a ground terminal receiving portion 35 are formed on the housing body 31. The pair of power terminal receiving portions 33 can each receive a pair of power terminals 11. The multiple signal terminal receiving portions 34 can each receive multiple signal terminals 12. The ground terminal receiving portion 35 can receive a ground terminal 13. Each terminal receiving portion 33, 34, and 35 is formed as a cylinder capable of receiving the corresponding terminal 11, 12, or 13.

[0067] In this embodiment, the power terminal housing 33 is arranged side-by-side in the Y direction, and a pair of power terminals 11 are also arranged side-by-side in the Y direction. This arrangement of the power terminals 11 is determined by the charging specifications. Multiple signal terminal housings 34 and multiple signal terminals 12 are arranged on both sides, with the central axis of the power terminals 11 as the boundary, in a direction orthogonal to both the axial direction and the arrangement direction of the power terminals 11. The ground terminal 13 and the ground terminal housing 35 are located on one side, with the central axis of the power terminals 11 as the boundary. The arrangement of the signal terminals 12 and the ground terminal 13 is also determined by the charging specifications, and the signal terminal housing 34 and the ground terminal housing 35 are formed accordingly.

[0068] Additionally, the housing body 31 has an outer frame portion 36. The outer frame portion 36 is formed as a cylinder surrounding the aforementioned terminal receiving portions 33, 34, and 35. At the middle portion of each terminal receiving portion 33, 34, and 35, the terminal receiving portions 33, 34, and 35 and the outer frame portion 36 are connected by, for example, a flat plate-shaped connecting portion (see reference). Figure 5 and Figure 6 The portion of the outer frame 36 that is further outward from the flat connecting portion forms an opening 36A for inserting and removing the external charging connector 7 (see reference). Figure 5 and Figure 6 Viewed along the insertion / removal direction, the power terminal housing 33, signal terminal housing 34, and ground terminal housing 35 are located inside the opening 36A. A cover unit 80 is mounted on the front of the housing body 31. A stop 60 is mounted on the rear of the housing body 31 (that is, on the side opposite to the opening 36A relative to the housing body 31).

[0069] Vehicle assembly section 32 is used to assemble charging connector 10 to assembly section 100 (see reference). Figure 1 The vehicle assembly part 32 is formed as a plate protruding from the middle part of the housing body 31 in the axial direction towards the periphery of the outer frame part 36. The vehicle assembly part 32 is assembled to the assembly part 100 using, for example, screws.

[0070] like Figure 7 and Figure 8 As shown, the housing 30 further includes a power line holding portion 37 and a ground line holding portion 38. That is, the power line holding portion 37 and the ground line holding portion 38 are included in the housing 30. The housing 30 including the power line holding portion 37 and the ground line holding portion 38 is formed by integral molding. When the power line holding portion 37 and the ground line holding portion 38 are integrally molded with the housing 30, it is advantageous in terms of reducing the number of processing steps and parts compared to the case where the power line holding portion 37 and the ground line holding portion 38 are separate parts. In addition, even if the power line holding portion 37 vibrates due to the vibration of the vehicle, the power line holding portion 37 vibrates in the same phase as the housing body 31 fixed to the vehicle. Therefore, it is possible to suppress the vibration of the power line 41 around the relay terminal 14 due to the phase deviation of the vibration of the relay terminal 14 held in the housing body 31 and the power line holding portion 37.

[0071] Furthermore, in this embodiment, the plate-shaped arm 39 protrudes from the outer frame 36 in the Y direction. The arm 39 extends in the direction in which the power line 41 and the ground line 43 extend (see reference). Figure 7 The power line holding part 37 is provided in the arm 39 at the top end along the protruding direction of the arm 39. Similarly, the ground wire holding part 38 is also provided in the arm 39. That is, in this embodiment, the arm 39 is integrally formed in the housing body 31, and the ground wire holding part 38 is integrally formed at the top end of the arm 39. It can be understood that the housing 30 is a component integrally molded from the same resin by means of a mold, comprising the housing body 31, the arm 39, and the ground wire holding part 38. Alternatively, the power line holding part 37 may be further integrally formed at the top end of the arm 39.

[0072] <Regarding the power line holding section 37>

[0073] Figure 9 This is a partially enlarged view showing the power line retaining part 37 and the ground wire retaining part 38 obliquely from the rear. (See attached image.) Figure 4 and Figure 7 As shown, the power line holding part 37 is provided, for example, at the top end of the arm portion 39 (away from the outer frame portion 36). Therefore, the power line holding part 37 can hold the power line at a position away from the terminal 14 when viewed in the insertion / removal direction. Furthermore, the power line holding part 37 can hold two power lines 41 (see reference...) Figure 7 There are two fixed settings.

[0074] The power line holding portion 37 holds the middle portion of the power line 41 extending from the power terminal 11. With this configuration, the power line holding portion 37 and the power terminal 11 are separately configured. Therefore, even if the portion of the power line 41 held in the power line holding portion 37 or the power line holding portion 37 vibrates, the vibration is not easily transmitted to the power terminal 11. Thus, the power terminal 11 itself is less prone to vibration, and friction between the power terminal 11 and the housing body 31 can be suppressed. Furthermore, the preferred distance between the power line holding portion 37 and the power terminal 11 is, for example, 80mm to 100mm. When the distance is greater than 80mm, the transmission of vibration of the power line 41 to the power terminal 11 can be effectively suppressed. Additionally, when the distance is less than 100mm, it is not necessary to increase the strength required for the power line holding portion 37 to support the weight of the power line 41, thereby reducing the manufacturing cost of the housing.

[0075] The power line retaining part 37 contacts the power line 41 at at least two different locations along the length of the power line 41 to retain the power line 41 (see reference). Figure 7 In this embodiment, the power line holding part 37 has multiple contact parts 371, etc., with the power line 41. In this embodiment, each power line holding part 37 has a pair of contact parts 371, 372 (or 373, 374) (Hereinafter, the description of "contact parts 373, 374" is the same as that of contact parts 371, 372, so the description is omitted.).

[0076] More specifically, the power line holding part 37 has a bottom 37a and a pair of sidewalls 37b erected from both sides of the bottom 37a. The spacing between the pair of sidewalls 37b is the same as or larger than the diameter of the power line 41. The protrusion dimension of the pair of sidewalls 37b is the same as or larger than the diameter of the power line 41. A groove-shaped space for receiving the power line 41 is formed between the bottom 37a and the pair of sidewalls 37b.

[0077] like Figure 9 As shown, contact portions 371 and 372 are provided on the inner surfaces of a pair of sidewall portions 37b in such a way that their positions change along the extension direction of the electric field line 41. Here, contact portion 371 is formed on the inner surface of one sidewall portion 37b, and contact portion 372 is formed on the inner surface of the other sidewall portion 37b. Thus, contact portions 371 and 372 can contact each other from opposite sides at different positions along the length direction of the electric field line 41. In this case, the contact portions 371 and 372 shorten the distance between the top edges of the pair of sidewall portions 37b at different positions along the length direction of the electric field line 41, therefore, compared to the case where the pair of contact portions are provided at the same position along the length direction, the electric field line 41 can be easily inserted between the pair of sidewall portions 37b. Contact portions 371 and 372 may also be formed on the inner surfaces of the same sidewall portion 37b.

[0078] The contact portions 371 and 372 are formed to protrude from the inner surface of the sidewall portion 37b. The distance between the protruding ends of the contact portions 371 and 372 and the inner surface of the sidewall portion 37b opposite to the contact portions 371 and 372 is set to be smaller than the diameter of the electric field line 41. As a result, the electric field line 41 is prevented from detaching when it is disposed between a pair of sidewall portions 37b by means of the contact portions 371 and 372.

[0079] Furthermore, the portion of the electric field line retaining part 37 formed by the bottom 37a and the side wall 37b has an arcuate surface along the circumference of the electric field line 41 (see reference). Figure 8 The end of the arcuate surface of the contact portions 371 and 372 on the side furthest from the bottom 37a connects to the electric field line 41 from the side opposite to the bottom 37a. In the protruding direction of the pair of sidewall portions 37b, the electric field line 41 is sandwiched between the bottom 37a and the top end of the arcuate surface, and is positioned and held in a certain position in this direction, effectively suppressing vibration of the electric field line 41 in this direction. Furthermore, when the distance between the pair of sidewall portions 37b is the same as or smaller than the diameter of the electric field line 41 (when slightly smaller), the electric field line 41 is also positioned in the direction connecting the pair of sidewall portions 37b, effectively suppressing vibration in this direction.

[0080] Furthermore, because the contact portions 371 and 372 contact the electric line 41 at two different points along its length, the transmission of lateral vibrations that transmit through the electric line 41 as a medium can be suppressed. For example, if the electric line is held with a single point of contact, vibrations at that contact point may be transmitted. If the electric line is held with two different points of contact along its length, vibrations at either point may be suppressed by the other holding portion. Therefore, the transmission of vibrations from the electric line 41 to the power terminal 11 can be effectively suppressed. In this embodiment, the electric line 41 is clamped by a pair of sidewall portions 37b extending within a predetermined range along its length, thereby suppressing vibrations in the direction connecting the pair of sidewall portions 37b. In addition, the two contact portions 371 and 372 contact the electric line 41 from the side opposite to the bottom 37a. As a result, vibrations in the direction where the pair of sidewall portions 37b are erected are effectively suppressed at two different points along the length of the electric line 41. Furthermore, from the viewpoint of effectively suppressing vibration transmission, the distance between the two points (central part) of the contact portions 371 and 372 is preferably about 20 mm.

[0081] <Regarding Cover Component 15>

[0082] like Figure 4 and Figure 8As shown, the cover member 15 is detachably mounted to the arm portion 39 and the power line holding portion 37. The cover member 15 covers the power line 41, preventing the power line 41 from detaching from the power line holding portion 37. The cover member 15 and the power line holding portion 37 cover the entire area surrounding the power line 41. In this embodiment, one cover member 15 is provided for both power line holding portions 37. The cover member 15 presses down on the two power lines 41. Figure 4 As shown, the cover member 15 has a locking portion 151 that engages with the protrusion 375 formed in the power line holding portion 37.

[0083] More specifically, a protrusion 375 is formed on the outer surface of at least one of the pair of sidewall portions 37b (see also...). Figure 9 Here, in the two power line holding parts 37, protrusions 375 are formed on the opposing surfaces of the two inner side wall parts 37b.

[0084] The cover member 15 has a cover portion 15a and a pair of sidewall portions 15b. The cover portion 15a is formed as a plate that covers the opening on the side opposite to the bottom 37a of the two electric line holding portions 37. The pair of sidewall portions 15b protrude from both sides of the cover portion 15a toward one of its main surfaces. The pair of sidewall portions 15b are able to cover the outer surface of the outermost sidewall portion 37b of the two electric line holding portions 37.

[0085] A plate-shaped engaging portion 15c protrudes from the middle of the width of the covering portion 15a (see reference). Figure 8 The engaging portion 15c has an engaging hole into which the protrusion 375 can be inserted.

[0086] Furthermore, the cover portion 15a covers the openings of the two power line holding portions 37, and a pair of sidewall portions 15b cover the two outer sidewall portions 37b. At this time, the protrusion 375 can engage with the engagement hole formed in the engagement portion 15c by elastic deformation of the engaging portion 15c. In addition, by elastic deformation of the engaging portion 15c, the engagement of the protrusion 375 with respect to the engagement hole formed in the engaging portion 15c can be released. Thus, the cover member 15 can be detachably assembled with respect to the power line holding portion 37. In addition, the method of fixing the cover member 15 and the power line holding portion 37 can be various methods including other known methods. The cover member 15 and the power line holding portion 37 can also be assembled using hinges or the like. In addition, the cover member 15 can also be assembled as two different cover members 15 for each power line holding portion 37.

[0087] <Regarding the grounding wire retaining section 38>

[0088] like Figure 4 and Figure 7As shown, the ground wire holding portion 38 is provided, for example, in the middle of the extending direction of one side of the arm portion 39, in a manner that protrudes outward in the width direction of the arm portion 39. Therefore, the arm portion 39 is positioned away from the outer frame portion 36. Thus, when viewed along the insertion / removal direction, the ground wire holding portion 38 can hold the ground wire 43 away from the grounding terminal 13.

[0089] The ground wire holding portion 38 holds the middle portion of the ground wire 43 extending from the grounding terminal 13. With this configuration, the ground wire holding portion 38 and the grounding terminal 13 are separately configured. Therefore, even if the portion of the ground wire 43 held in the ground wire holding portion 38 or the ground wire holding portion 38 vibrates, the vibration is difficult to transmit to the grounding terminal 13. Thus, the grounding terminal 13 itself is less prone to vibration, suppressing friction between the grounding terminal 13 and the housing body 31. Furthermore, the preferred distance between the ground wire holding portion 38 and the grounding terminal 13 is, for example, 50mm to 70mm. When the distance is greater than 50mm, the transmission of vibration of the ground wire 43 to the grounding terminal 13 can be effectively suppressed. Additionally, when the distance is less than 70mm, it is not necessary to increase the strength required for the ground wire holding portion 38 to support the weight of the ground wire 43, thus reducing the manufacturing cost of the housing 30. The distance between the ground wire holding portion 38 and the grounding terminal 13 can also be shorter than the distance between the power line holding portion 37 and the power supply terminal 11. This is because: ground wire 43 is usually thinner than power line 41, so vibration will not be a problem as it is with power line 41.

[0090] The ground wire retaining part 38 contacts the ground wire 43 at at least two different locations along the length of the ground wire 43 to retain the ground wire 43 (see reference). Figure 7 In this embodiment, the ground wire holding part 38 has a pair of contact parts 381, 382 with the ground wire 43.

[0091] More specifically, the ground wire holding portion 38 has a bottom 38a and a pair of sidewall portions 38b extending from both sides of the bottom 38a. The spacing between the pair of sidewall portions 38b is the same as or larger than the diameter of the ground wire 43. The protrusion dimension of the pair of sidewall portions 38b is the same as or larger than the diameter of the ground wire 43. A groove-shaped space for receiving the ground wire 43 is formed between the bottom 38a and the pair of sidewall portions 38b.

[0092] like Figure 9As shown, contact portions 381 and 382 are provided on the inner surfaces of a pair of sidewall portions 38b in such a way that their positions change along the extension direction of the ground wire 43. Here, contact portion 381 is formed on the inner surface of one sidewall portion 38b, and contact portion 382 is formed on the inner surface of the other sidewall portion 38b. Thus, contact portions 381 and 382 can contact each other from opposite sides at different positions along the length direction of the ground wire 43. In this case, the contact portions 381 and 382 shorten the distance between the top edges of the pair of sidewall portions 38b by being at different positions along the length direction of the ground wire 43. Therefore, compared to the case where the pair of contact portions are provided at the same position along the length direction, the ground wire 43 can be easily inserted between the pair of sidewall portions 38b. Contact portions 381 and 382 can also be formed on the inner surfaces of the same sidewall portion 38b.

[0093] The contact portions 381 and 382 are formed to protrude from the inner surface of the sidewall portion 38b. The distance between the protruding ends of the contact portions 381 and 382 and the inner surface of the sidewall portion 38b opposite to the contact portions 381 and 382 is set to be smaller than the diameter of the ground wire 43. Thus, the ground wire 43 is prevented from detaching by means of the contact portions 381 and 382 when it is disposed between a pair of sidewall portions 38b.

[0094] Furthermore, the side view cross-sectional shape of the portion of the ground wire holding part 38 formed by the side wall portion 38b and the contact portion 381, and the portion formed by the side wall portion 38b and the contact portion 382, ​​has an arc-shaped surface along the circumference of the ground wire 43 (see reference). Figure 8 The end of the arcuate surface of the contacts 381 and 382, ​​on the side furthest from the bottom 38a, connects to the ground wire 43 from the side opposite to the bottom 38a. In the protruding direction of the pair of sidewall portions 38b, the ground wire 43 is sandwiched between the bottom 38a and the contacts 381 and 382 of the arcuate surface, and is positioned and held in a certain position in this direction, thereby firmly fixing the ground wire 43 in this direction. Furthermore, when the distance between the pair of sidewall portions 38b is the same as or smaller than the diameter of the ground wire 43 (when slightly smaller), the ground wire 43 is also positioned in the direction connecting the pair of sidewall portions 38b, and is firmly fixed in this direction. In addition, due to the recent trend of increasing the diameter of the ground wire 43, measures to prevent vibration of the ground wire 43 outside the charging connector 10 from being transmitted to the grounding terminal 13 have become a problem, but this configuration also has the effect of suppressing the transmission of vibration of the ground wire 43.

[0095] Furthermore, because the contact portions 381 and 382 contact the ground wire 43 at two different points along its length, the ground wire 43 can be more reliably secured, similar to the power line holding portion 37. Additionally, the transmission of lateral vibrations transmitted through the ground wire 43 can be suppressed. For example, if the ground wire 43 is held with a single point of contact, vibrations at that contact point may be transmitted. If the ground wire 43 is held with two different points of contact along its length, vibrations at either point can be suppressed by the other holding portion. Therefore, the transmission of vibrations from the ground wire 43 to the grounding terminal 13 can be effectively suppressed. In this embodiment, the ground wire 43 is held by a pair of sidewall portions 38b extending within a predetermined range along its length, thereby suppressing vibrations in the direction connecting the pair of sidewall portions 38b. Furthermore, the two contact portions 381 and 382 are positioned at different locations in the vertical direction (Z direction) of the ground wire holding portion 38 and in the extending direction (Y direction) of the ground wire 43. Therefore, compared to the case where the configuration differs only in the vertical direction (i.e., the two contact portions 381 and 382 are positioned at the same location in the extension direction of the ground wire 43 and are vertically opposed), the insertion of the ground wire 43 into the ground wire holding portion 38 becomes easier. Furthermore, the two contact portions 381 and 382 contact the ground wire 43 from the side opposite to the bottom 38a. Thus, vibrations in the direction in which the pair of sidewall portions 38b are erected are effectively suppressed at two different points along the length of the ground wire 43. Moreover, from the viewpoint of effectively suppressing vibration transmission, the distance between the two points (at the center) of the contact portions 381 and 382 is preferably around 20 mm.

[0096] As described above, the ground wire 43 is held by the ground wire holding part 38, thereby keeping the ground wire 43 in a bent state within the wire sheath 90, which will be described later. This makes it difficult for the ground wire 43 to interfere with external components (other parts within the vehicle 1). This facilitates, for example, the assembly of external components. Furthermore, the wire holding structure can be simplified.

[0097] <Regarding cover components 16>

[0098] like Figure 4 , Figure 8 as well as Figure 9 As shown, the cover member 16 is detachably mounted to the ground wire holding part 38. The cover member 16 covers the ground wire 43, preventing the ground wire 43 from detaching from the ground wire holding part 38. The cover member 16 and the ground wire holding part 38 cover the entire area surrounding the ground wire 43. The cover member 16 presses down on the ground wire 43. Figure 4 and Figure 9 As shown, the cover member 16 has a locking portion 16b that engages with the protrusion 383 formed in the ground wire holding portion 38.

[0099] More specifically, such as Figure 9As shown, a protrusion 383 is formed on at least one outer surface (in this case, both outer surfaces) of a pair of sidewall portions 38b. The cover member 16 has a covering portion 16a, a pair of engaging portions 16b, and a retaining groove 16d formed on the side opposite to the covering portion 16a as a guide portion. Figure 7 As shown, the retaining groove 16d opens in the direction intersecting the length direction of the signal line 42 (X direction). Furthermore, the retaining groove 16d is formed along the length direction of the signal line 42 (Y direction). The depth and width of the retaining groove 16d vary depending on the type and number of wires guided by the retaining groove 16d. The depth and width of the retaining groove 16d can also be large enough to accommodate multiple (six in this embodiment) signal lines 42. Multiple signal terminals 12 are housed in the charging connector 10. Therefore, multiple signal lines 42 connected to the signal terminals 12 are led into the vehicle 1. Because multiple wires are led out in this way, the wiring layout within the vehicle 1 becomes complicated. Therefore, from the viewpoint of simplified layout, it is preferable that more of the signal lines 42 connected to the signal terminals 12 are guided by the retaining groove 16d. Furthermore, because the retaining groove 16d is formed in this way, during wire assembly operations, the operator can intuitively determine that the retaining groove 16d is the wire routing location. Therefore, when such a retaining groove 16d is formed, workability is improved.

[0100] A pair of engaging portions 16b protrude from both sides of the covering portion 16a in the width direction (see reference). Figure 9 A protrusion 383 is formed in the engaging portion 16b, into which an engaging hole 16c can be inserted.

[0101] The cover portion 16a is formed as a plate covering the opening on the side opposite to the bottom 38a of the ground wire holding portion 38. The thickness of the cover portion 16a is separated by the space surrounded by the ground wire holding portion 38 and the cover portion 16a and the holding groove 16d formed on the opposite side of the cover portion 16a. That is, the cover portion 16a is an example of a wall portion that separates the ground wire 43 held by the ground wire holding portion 38 and the signal wire 42 held by the holding groove 16d. The surface of the cover portion 16a on the side of the ground wire holding portion 38 may also have an arcuate groove corresponding to the circumferential surface of the ground wire 43. A pair of engaging portions 16b protrude from both sides of the cover portion 16a toward one of the main surfaces of the cover portion 16a. The pair of engaging portions 16b engage with a pair of protrusions 383 formed on the outer surface of the side wall portion 38b of the ground wire holding portion 38. In the ground wire holding part 38, a pair of engaging parts 16b engage with the corresponding protrusions 383 of each engaging part 16b, thus holding the ground wire 43 in a surrounding manner by the ground wire holding part 38 and the cover member 16. Furthermore, the extensions 16e on both sides of the cover part 16a in the width direction can also connect to the outside of the portions of the pair of sidewall parts 38b where contact portions 381 and 382 are formed. Therefore, when the cover member 15 is on, the contact portions 381 and 382 are difficult to shift outwards, preventing the ground wire 43 from dislodging from the ground wire holding part 38. Additionally, when the ground wire holding part 38 and the cover member 16 are engaged, firstly, the pair of engaging parts 16b cover the outside of the sidewall parts 38b. At this time, through elastic deformation of the engaging parts 16b, the protrusions 383 can engage with the engaging holes 16c formed in the engaging parts 16b. Furthermore, by elastically deforming the engaging portion 16b, the locking of the protrusion 383 relative to the engaging hole 16c formed in the engaging portion 16b can be released. Thus, the cover member 16 can be detachably assembled with respect to the ground wire retaining portion 38. The engaging portions of the pair of engaging portions 16b and the pair of protrusions 383 are preferably positioned in the gap 39b formed between the side wall portion 38b and the arm portion 39 or the auxiliary rod 39a. Therefore, the engaging state of the pair of engaging portions 16b and the pair of protrusions 383 is difficult to release. Moreover, the method of fixing the cover member 16 and the ground wire retaining portion 38 can be applied to various methods, including other known methods. The cover member 16 and the ground wire retaining portion 38 can also be assembled using hinges or other methods that allow for opening and closing.

[0102] Thus, relative to the cover member 16, a guide portion for the signal line 42 is provided in the ground wire holding portion 38, separated from the ground wire 43 by the wall portion, so multiple wires can be laid in a concentrated manner, simplifying the wire laying path. Furthermore, because the ground wire 43 is held separated from the signal line 42 by the wall portion, the ground wire holding portion 38 can firmly hold the ground wire 43 in a certain position. Additionally, because it can be laid separated from the ground wire 43 by the wall portion and can be laid near the ground wire 43, it can be led out from the same wire outlet 95 of the outer component. Therefore, the wire laying path on the outside of the outer component is also simplified.

[0103] <Regarding the curved section 43a>

[0104] The ground wire 43 has a bent portion 43a located between the grounding terminal 13 and the ground wire holding portion 38. For example... Figure 2 As shown, the ground wire 43 bends from the length direction (X direction) of the ground terminal 13 to a direction orthogonal to the length direction of the ground terminal 13 (the insertion / removal direction of the external charging connector) via the bending portion 43a. The ground wire 43 is generally thinner than the power line 41 and is more flexible. Therefore, unlike the power line 41, the ground wire 43 does not utilize the relay terminal 14, and its extension direction can be changed. Therefore, the ground wire 43, bent by the bending portion 43a in a direction orthogonal to the length direction of the ground terminal 13 (the insertion / removal direction of the external charging connector), is held by the ground wire holding portion 38 in a direction orthogonal to the ground terminal 13 as described above. In this embodiment, the ground wire 43 bends in a direction orthogonal to the length direction of the ground terminal 13 (the insertion / removal direction of the external charging connector) via the bending portion 43a, and the bending direction is not limited to an orthogonal direction. Any intersecting direction is acceptable. However, it is preferable that the extension direction of the wire 43 is aligned with the direction of the wire outlet 95 of the sheath 90.

[0105] In this way, the ground wire 43 is maintained at a position far from the grounding terminal 13 by means of the bend 43a, so the structure can be simplified, especially in the wiring surface, compared with the structure that maintains the bend as a whole.

[0106] <Regarding the curved section 42a>

[0107] Both signal line 42 and ground line 43 have a bend 42a located between signal terminal 12 and cover member 16. Furthermore, like ground line 43, signal line 42 does not utilize relay terminal 14, and its extension direction can be changed. Therefore, signal line 42, bent in the direction intersecting signal terminal 12 (the insertion / removal direction of the external charging connector) via this bend 42a, is held by the retaining groove 16d of cover member 16 in the direction intersecting ground terminal 13, as described above.

[0108] <Stop body 60>

[0109] like Figure 4 and Figure 6 As shown, the stop body 60 prevents the terminals 11, etc., from disengaging from the housing 30. The stop body 60 includes a terminal pressing portion 61 (see reference). Figure 6The terminal pressing part 61 is located behind the terminals 11 and 12 of the housing 30. This prevents the terminals 11 and 12 from disengaging rearward from the housing 30. In other words, the stop 60 holds the terminals 11 and 12 together with the housing body 31. The terminal pressing part 61 includes a rear cover 62 and multiple protruding cylindrical parts 63.

[0110] The rear cover 62 closes the opening at the rear of the outer frame 36. Multiple through holes 62a are formed in the rear cover 62 (see reference). Figure 7 Multiple through holes 62a are formed at positions corresponding to the terminal housings 33, 34, and 35. The power terminal 11 and the relay terminal 14 are fastened with screws while in contact through the through holes corresponding to the power terminal 11. The relay terminal 14 is disposed on the back side of the rear cover 62. Signal lines 42 and ground lines 43 are led out from the through holes corresponding to the signal terminal 12 and the ground terminal 13.

[0111] like Figure 6 As shown, multiple protruding cylindrical portions 63 protrude forward (towards the housing 30 side) from the rear cover portion 62. These protruding cylindrical portions 63 are formed at positions corresponding to the terminal receiving portions 33, 34, and 35. Each protruding cylindrical portion 63 communicates with each through hole 62a. The top end of each protruding cylindrical portion 63 is inserted into the corresponding terminal receiving portion 33, 34, or 35, pressing down on the corresponding terminals 11, 12, and 13 from the rear.

[0112] like Figure 4 As shown, locking portions 30p and 60p are provided on the housing 30 and the stop body 60. In this embodiment, the locking portions include a locking protrusion formed on the housing 30 and a locking piece formed on the stop body 60. By locking the locking piece with the locking protrusion, the housing 30 and the stop body 60 are maintained in a mutually assembled state.

[0113] <Regarding the 90mm cable sheath>

[0114] like Figure 4 and Figure 6 As shown, the cable sheath 90 connects the housing 30 and the cover components 15 and 16 to the opening 36A (see reference). Figure 5 and Figure 6 The opposite side is covered. More specifically, such as Figure 4 As shown, the protective sleeve 90 covers the housing 30 and cover members 15 and 16 from the inside of the vehicle 1. Figure 3 and Figure 4As shown, the cable sheath 90 includes a first protective portion 91 and a second protective portion 94. The first protective portion 91 covers the outer frame portion 36 of the housing 30 (containing the power terminal 11, signal terminal 12, and ground terminal 13 disposed inside the outer frame portion 36) and the relay terminal 14. The cable sheath 90 also covers the stoppers 60 that press these terminals 11, 12, and 13. The second protective portion 94 covers the power line retaining portion 37, the ground wire retaining portion 38, and the cover members 15 and 16. The cable sheath 90 is formed of a flexible material. For example, the cable sheath 90 is an elastic material such as ethylene-propylene-diolefin rubber.

[0115] A binding strap 98 is fitted to the outer surface of the housing outlet 92 of the cable sheath 90. The cable sheath 90 is fitted to the housing 30, which includes the power line retaining part 37 and the ground line retaining part 38, by means of the binding strap 98.

[0116] like Figure 5 As shown, a wire outlet 95 is formed in the second protection section 94. Through the wire outlet 95, power supply terminals 11 are connected via relay terminals 14 (see reference 14). Figure 4 and Figure 6 The other end of the connected power line 41 extends outwards from the sheath 90. The sheath 90 has three wire outlets 95. Two of the three wire outlets 95 are configured for two power lines 41. Each of the two wire outlets 95 passes through one power line 41. The remaining wire outlet 95 passes through a signal line 42 and a ground line 43. These signal lines 42 and ground lines 43 are the individual wires 40 guided by the ground wire retainer 38 and the retaining groove 16d of the cover member 16.

[0117] Furthermore, signal line 42 typically uses a wire with a smaller diameter than power line 41. Therefore, it is less likely to cause the same problem of vibration transmission to the terminals as with power line 41. Consequently, in signal line 42, it is possible that it is not laid along the retaining groove 16d of cover member 16, but rather along the outer side of ground wire retaining portion 38. In this case, if it is laid via the side wall portion 38b of ground wire retaining portion 38, ground wire retaining portion 38 can securely hold ground wire 43 in a fixed position.

[0118] [Postscript]

[0119] In this embodiment, an example is described where the first terminal and the first wire are signal terminal 12 and signal line 42, and the thicker second terminal and the second wire are ground terminal 13 and ground wire 43. However, the first terminal and the first wire, and the thicker second terminal and the second wire are not limited to the above example. For example, the first terminal and the first wire may be signal terminal 12 and signal line 42, and the thicker second terminal and the second wire may be power supply terminals and power lines.

[0120] In the above embodiment, the power line retaining part 37 and the ground line retaining part 38 are integrally formed with the housing 30. However, the power line retaining part 37 and the ground line retaining part 38 may also be composed of separate components from the housing 30.
