[0009] [Description of the embodiments of the present disclosure] First, embodiments of the present disclosure will be listed and described. [1] The charging connector of the present disclosure is a charging connector that mates with a mating connector in a first direction, and includes a housing, terminals accommodated in the housing, electric wires electrically connected to the terminals, and a cover assembled to the housing, wherein the cover includes a wire guide portion that guides the electric wires in a second direction intersecting the first direction and holds the electric wires, and a lock portion that is arranged at a position overlapping the wire guide portion in the first direction, and the housing includes a lock receiving portion that engages with the lock portion in the first direction.

[0010] With this configuration, the locking portion of the cover and the lock receiving portion of the housing are locked in the first direction, thereby preventing the cover from rattling relative to the housing. This prevents displacement of the wire guide portion of the cover, thereby preventing vibration of the wires relative to the housing. Furthermore, because the locking portion is positioned so as to overlap with the wire guide portion in the first direction, the charging connector can be prevented from becoming large.

[0011] [2] In the above [1], it is preferable that the housing has a housing main body having an outer peripheral surface that is circular when viewed in the first direction and in which the terminal is arranged, the cover has an inner peripheral surface that is circular when viewed in the first direction and a cylindrical portion that is arranged on the outside of the housing main body, the locking portion has a first portion extending from the cylindrical portion in the first direction and a second portion extending from a tip of the first portion in a third direction that is perpendicular to both the first direction and the second direction, and the lock receiving portion protrudes from the outer peripheral surface of the housing main body.

[0012] With this configuration, the locking portion and the lock receiving portion can be easily engaged with each other by sliding the cylindrical portion relative to the housing body so as to rotate it around the central axis of the cylindrical portion.

[0013] [3] Preferably, the charging connector of [2] above further includes an annular sealing member disposed between the housing body and the cylindrical portion.

[0014] With this configuration, it is possible to seal off the water between the housing and the cover.

[0015] [4] In any one of the above [1] to [3], it is preferable that the locking portion is engaged with the lock receiving portion in a third direction perpendicular to both the first direction and the second direction.

[0016] With this configuration, the cover can be positioned relative to the housing in the third direction.

[0017] [Details of the embodiments of the present disclosure] The following describes embodiments of the present disclosure. The present disclosure is not limited to these examples, but is defined by the claims, and is intended to include all modifications within the meaning and scope of the claims. In the drawings, for the sake of convenience, some components may be exaggerated or simplified. Furthermore, the dimensional ratios of the components may differ between drawings. In this specification, "orthogonal" does not only refer to a strict orthogonal relationship, but also includes a roughly orthogonal relationship within the scope of the operation and effect of the present embodiment.

[0018] In addition, "facing" in this specification refers to surfaces or components facing each other, and includes not only cases where they are completely facing each other, but also cases where they are partially facing each other. In addition, "facing" in this specification includes both cases where a component separate from the two components is interposed between the two components, and cases where nothing is interposed between the two components.

[0019] In each drawing, three mutually perpendicular directions are shown, and the three directions are respectively indicated as a first direction D1, a second direction D2, and a third direction D3. That is, the first direction D1 and the second direction D2 are perpendicular to each other, the first direction D1 and the third direction D3 are perpendicular to each other, and the second direction D2 and the third direction D3 are perpendicular to each other. By indicating each direction with an arrow on both sides of the solid line, not only the direction of the arrow on the side with the symbol but also the direction of the arrow on the side without the symbol is considered to indicate the corresponding direction.

[0020] <Embodiment> An embodiment of the present disclosure will be described with reference to Figures 1 to 11. In the following description, the front-rear direction is an example of the first direction D1. For multiple identical members, only some of the members may be assigned reference numerals, and the reference numerals for the other members may be omitted.

[0021] (Charging connector 10) The charging connector 10 of this embodiment is mounted on a vehicle such as an electric vehicle or a hybrid vehicle. The charging connector 10 is used to charge a battery mounted on the vehicle. The battery can be charged by connecting the charging connector 10 to a mating connector provided outside the vehicle. The charging connector 10 and the mating connector are adapted to mate in a first direction D1 (front-rear direction). Specifically, as shown in FIG. 1 , the charging connector 10 opens on one side (front) in the first direction D1. The mating connector is adapted to be fitted to the charging connector 10 from the front.

[0022] 2 , the charging connector 10 includes a housing 20, two terminals 30 accommodated in the housing 20, a retainer 40 that prevents the two terminals 30 from coming loose from the housing 20, two electric wires 50, two relay terminals 51, and a cover 60 that is attached to the housing 20. The terminals 30 and the electric wires 50 are electrically connected via the relay terminals 51. The charging connector 10 further includes a plurality of signal terminals different from the terminals 30.

[0023] (Housing 20) The housing 20 is made of insulating synthetic resin. As shown in FIG. 5, the housing 20 includes a housing main body 21 and a hood portion 22. The hood portion 22 includes a rear wall 22A extending from the housing main body 21 in a direction perpendicular to the front-rear direction, and a fitting tubular portion 22B extending forward from the rear wall 22A. The hood portion 22 opens forward and can be fitted with a mating connector. The housing main body 21 is formed with a terminal accommodating portion 23 that accommodates the terminal 30. The terminal accommodating portion 23 is formed to penetrate the housing main body 21 in the front-rear direction. The terminal accommodating portion 23 extends forward from the rear wall 22A and is disposed inside the fitting tubular portion 22B. Furthermore, as shown in FIGS. 2 and 4, the housing main body 21 is formed with a signal terminal accommodating portion 24 that accommodates a signal terminal.

[0024] The housing 20 is fixed to the vehicle body or the like via the bracket 11 by fastening bolts. As shown in FIGS. 2 and 4, the bracket 11 has a through-hole 11A into which the front portion of the fitting tubular portion 22B is inserted. As shown in FIG. 2, the housing 20 has a fixing piece 25 that is fixed to the bracket 11. The fixing piece 25 extends outward from the fitting tubular portion 22B. The fixing piece 25 has an insertion hole 25B through which a mounting screw 25A is inserted. The mounting screw 25A is inserted into the insertion hole 25B and then fastened to the bracket 11, thereby fixing the housing 20 to the bracket 11 (see FIG. 3).

[0025] (Lock receiving part 27) As shown in FIG. 5, the housing main body 21 has a peripheral wall portion 26 that covers the terminal accommodating portion 23 from the outer periphery. The peripheral wall portion 26 extends from the rear wall 22A to the other side (rear) in the first direction D1. As shown in FIG. 6, the peripheral wall portion 26 has an outer peripheral surface 26A that is circular when viewed from the rear. As shown in FIG. 9, the housing 20 has a lock receiving portion 27 that protrudes from the outer peripheral surface 26A of the peripheral wall portion 26. The lock receiving portion 27 is generally block-shaped. As shown in FIG. 11, the lock receiving portion 27 has a recess 27A that is recessed rearward from the front end surface of the lock receiving portion 27.

[0026] 7 and 9, the housing 20 has a plurality of fixing portions 28 disposed outside the peripheral wall portion 26. The fixing portions 28 are columnar and extend in the front-to-rear direction. Mounting screws 64 can be fastened to the fixing portions 28. The fixing portions 28 are members for fixing the cover 60 to the housing 20.

[0027] (Terminal 30) As shown in Figure 2, the terminal 30 is a female terminal that is cylindrical overall and opens forward. The terminal 30 includes a terminal body 31 that is substantially cylindrical, and a plurality of contact pieces 32 that extend forward from the front end of the terminal body 31. A gap is formed between each pair of adjacent contact pieces 32. Each contact piece 32 is elastically flexible and deformable. When a pin of a mating terminal provided in a mating connector enters inside the plurality of contact pieces 32, each contact piece 32 is flexible and deformed outward, thereby elastically contacting the pin.

[0028] As shown in FIG. 9, the terminal 30 is formed with a locking groove 33 recessed from the terminal body 31. The locking groove 33 opens to the rear. The inner surface of the front end of the locking groove 33 forms a locking portion 34 that locks with the retainer 40. As shown in FIG. 5, a screw hole 35 is formed inside the terminal body 31. The screw hole 35 is formed to open to the rear. A female thread is formed on the inner peripheral surface of the screw hole 35. A bolt 36 can be screwed into the screw hole 35. A male thread is formed on the shaft of the bolt 36. With a relay terminal 51 disposed at the rear end of the terminal body 31, the terminal 30 and the relay terminal 51 are connected by tightening the bolt.

[0029] The signal terminal is smaller than the terminal 30. The signal terminal has a plurality of contact pieces similar to those of the terminal 30, and a signal line connecting portion connected to the rear of the plurality of contact pieces. The signal line connecting portion is connected to a signal line.

[0030] As shown in Fig. 2, the retainer 40 includes a substantially disk-shaped retainer body 41 and a cylindrical retaining portion 42 that protrudes forward from the retainer body 41. As shown in Fig. 9, a protrusion 43 extending in the front-to-rear direction is formed on the inner peripheral surface of the retaining portion 42. The protrusion 43 engages with the locking portion 34 from behind, thereby preventing the terminal 30 from coming out of the housing 20.

[0031] As shown in FIG. 2, the retainer 40 further includes a retaining projection 44 that projects forward from the retainer body 41. The retaining projection 44 is generally C-shaped when viewed from the front. The retaining projection 44 is formed integrally with a slit 45 that is cut out toward the outer periphery of the retainer body 41. The signal wire connected to the signal terminal is guided through the slit 45 into the retaining projection 44. The retaining projection 44 engages with the rear end of the signal terminal, preventing the signal terminal from coming out of the housing 20.

[0032] The retainer 40 is adapted to be attached to the housing 20 from the rear. A plurality of fixing holes 46 are formed in the retainer body 41, penetrating in the front-to-rear direction. The retainer 40 is fixed to the housing 20 by passing mounting screws 47 through the fixing holes 46 of the retainer 40 and fastening the mounting screws 47 to the housing body 21. As shown in FIG. 9 , the retainer 40 is adapted to be disposed inside the peripheral wall portion 26. The front ends of the protrusions 43 are engaged with the locking portions 34 of the terminals 30 from the rear, thereby preventing the terminals 30 from slipping out rearward.

[0033] (Wire 50) As shown in FIG. 2, the electric wire 50 has a core wire covered with an insulating coating. The electric wire 50 is a thick electric wire, for example, about 1.25 sq. The electric wire 50 is thicker than a signal wire. The relay terminal 51 includes a flat wire connection portion 52 to which the core wire of the electric wire 50 is welded, and a terminal connection portion 53 disposed perpendicular to the electric wire connection portion 52. A bolt hole 54 through which the shank of the bolt 36 passes is formed in the terminal connection portion 53. As shown in FIG. 5, the terminal connection portion 53 is overlapped with the rear end of the terminal 30, and the bolt hole 54 and the screw hole 35 are arranged coaxially, and then the shank of the bolt 36 is threaded into the screw hole 35 through the bolt hole 54. As shown in FIG. 1, the electric wire 50 is drawn out from the cover 60 to the outside of the charging connector 10 in a second direction D2 intersecting a mating direction (first direction D1) with the mating connector.

[0034] (Cover 60) As shown in FIGS. 1 and 2, the cover 60 includes a cylindrical portion 61 and an electric wire guide portion 62 extending from the cylindrical portion 61 in the second direction D2. The cylindrical portion 61 is made of an insulating synthetic resin. As shown in FIG. 5, the cylindrical portion 61 is disposed rearward relative to the housing main body 21. The cylindrical portion 61 covers the relay terminals 51, the electric wires 50, the signal wires, etc. The front portion of the cylindrical portion 61 is disposed outside the peripheral wall portion 26 of the housing 20. As shown in FIG. 6, the cylindrical portion 61 has an inner peripheral surface 61A that is circular when viewed from the front-to-rear direction. An annular seal member S1 is disposed between the inner peripheral surface 61A of the cylindrical portion 61 and the outer peripheral surface 26A of the peripheral wall portion 26. The seal member S1 is made of an elastic material such as rubber. The seal member S1 provides a waterproof seal between the housing 20 and the cylindrical portion 61.

[0035] As shown in Fig. 2, a plurality of mounting portions 63 are formed at the front end of the cylindrical portion 61 so as to protrude outward. The mounting portions 63 are arranged at positions that do not overlap with the wire guide portions 62 when viewed from the front-rear direction. The mounting portions 63 are formed with insertion holes 63A through which mounting screws 64 are passed. The cover 60 is fixed to the housing 20 by passing the mounting screws 64 through the insertion holes 63A of the mounting portions 63 and fastening the mounting screws 64 to the fixing portions 28 of the housing 20 (see Figs. 7 and 8).

[0036] (Lock part 65) As shown in FIGS. 2 and 9, the cover 60 includes a locking portion 65 provided at the front end of the cylindrical portion 61. The locking portion 65 is disposed in a position overlapping the wire guide portion 62 when viewed from the front-rear direction. As shown in FIGS. 7 and 11, the locking portion 65 includes a first portion 65A extending forward from the front end of the cylindrical portion 61 and a second portion 65B extending from a tip of the first portion 65A in a third direction D3 perpendicular to both the first direction D1 and the second direction D2 (the direction perpendicular to the paper surface of FIGS. 7 and 11). The locking portion 65 is generally L-shaped when viewed from the second direction D2. As shown in FIG. 7, the locking portion 65 is disposed near the center of the wire guide portion 62 in the third direction D3. As shown in FIG. 11, the locking portion 65 and the front end of the cylindrical portion 61 form a receiving space 66 that receives the lock receiving portion 27. The locking portion 65 includes a protrusion 65C that protrudes rearward from the second portion 65B.

[0037] The locking portion 65 engages with the lock receiving portion 27. More specifically, as shown in FIG. 9, the second portion 65B of the locking portion 65 engages with the lock receiving portion 27 in the front-to-rear direction (first direction D1). This prevents the wire guiding portion 62 from rattling relative to the housing 20 in the first direction D1. Furthermore, as shown in FIG. 11, the protruding portion 65C is disposed within the recessed portion 27A, so that the protruding portion 65C and the recessed portion 27A engage with each other in the third direction D3. This allows the cover 60 to be positioned relative to the housing 20 in the third direction D3.

[0038] Unlike the present embodiment, if an attachment portion were to be provided on the wire guide portion 62, as with the tubular portion 61, the attachment screw would be fastened in the first direction D1, and therefore the attachment portion would have to be formed to protrude from the wire guide portion 62 in a direction perpendicular to the first direction D1 (see FIG. 2 ). This would increase the size of the charging connector 10 in the direction perpendicular to the first direction D1. On the other hand, in the present embodiment, instead of providing an attachment portion on the wire guide portion 62, the locking portion 65 is formed on the tubular portion 61 on the front side of the wire guide portion 62. This makes it possible to prevent the wire guide portion 62 from rattling relative to the housing 20 while avoiding an increase in the size of the charging connector 10. As a result, rattling of the wire guide portion 62, which holds the electric wire 50, relative to the housing 20 is suppressed, thereby suppressing vibration of the electric wire 50.

[0039] (Assembling the cover 60 to the housing 20) When assembling the cover 60 and the housing 20, the seal member S1 is attached to the outer peripheral surface 26A of the peripheral wall portion 26, and the front end of the cylindrical portion 61 is fitted to the peripheral wall portion 26 from the outside (see FIGS. 5 and 6). At this time, as shown in FIG. 10, the cylindrical portion 61 and the peripheral wall portion 26 are positioned in the circumferential direction D4 so that the locking portion 65 does not interfere with the lock receiving portion 27 in the front-rear direction and the receiving space 66 faces the lock receiving portion 27 in the circumferential direction D4. The circumferential direction D4 is a direction along the inner peripheral surface 61A of the cylindrical portion 61 and the outer peripheral surface 26A of the peripheral wall portion 26 (see FIG. 6). In other words, the circumferential direction D4 is a direction of rotation around the central axis of the cylindrical portion 61. The circumferential direction D4 is a direction perpendicular to the first direction D1 (front-rear direction) and is included in the third direction D3.

[0040] When the cover 60 is slid relative to the housing 20 in the circumferential direction D4 so that the lock receiving portion 27 enters the receiving space 66 while the front end of the cylindrical portion 61 is fitted with the peripheral wall portion 26, the protrusion 65C engages with the front end surface of the lock receiving portion 27, and the lock portion 65 is elastically deformed. When the cover 60 is further rotated in the circumferential direction D4, the protrusion 65C is disposed within the recess 27A, causing the lock portion 65 to return to its original shape, and the lock portion 65 and the lock receiving portion 27 are engaged with each other (see FIG. 11 ). Due to the responsiveness of the elastic deformation and return deformation of the lock portion 65, the lock portion 65 and the lock receiving portion 27 can be engaged with each other even when the lock portion 65 is not visible to the operator.

[0041] After the locking portion 65 and the lock receiving portion 27 are locked together, the mounting screw 64 is inserted into the insertion hole 63A of the mounting portion 63 and fastened to the fixing portion 28. This completes the assembly of the cover 60 to the housing 20.

[0042] (wire lead-out portion 62) As shown in FIGS. 1 and 7, the wire guide portion 62 has a rectangular box shape when viewed from the second direction D2. As shown in FIG. 2, the wire guide portion 62 includes a wire accommodating portion 67 extending from the tubular portion 61 toward one side in the second direction D2, a holding member 68, and a pressing member 69. The wire accommodating portion 67 is formed integrally with the tubular portion 61. The wire accommodating portion 67 is made of insulating synthetic resin. The wire accommodating portion 67 has a rectangular tubular shape. As shown in FIG. 8, the wire accommodating portion 67 has two openings 67A that open to one side in the second direction D2 (the lower side in FIG. 8). The two openings 67A are aligned in a third direction D3 that is perpendicular to both the first direction D1 and the second direction D2.

[0043] The holding member 68 is made of an elastic material such as rubber. The holding member 68 is disposed within the opening 67A. The holding member 68 holds the electric wire 50 and absorbs vibrations of the electric wire 50. The holding member 68 includes a wire enclosing portion 68A and a plate-shaped portion 68B extending from the wire enclosing portion 68A in a direction perpendicular to the second direction D2. The wire enclosing portion 68A is cylindrical and holds the electric wire 50 in a compressed state. The wire enclosing portion 68A has an insertion hole 68C through which the electric wire 50 is inserted. The insertion hole 68C penetrates the wire enclosing portion 68A in the second direction D2. The inner peripheral surface of the insertion hole 68C and the outer peripheral surface of the electric wire 50 are in liquid-tight contact. The outer peripheral surface of the plate-shaped portion 68B and the inner peripheral surface of the opening 67A are in liquid-tight contact.

[0044] The pressing member 69 is made of insulating synthetic resin. The pressing member 69 is assembled to the wire accommodating portion 67 while pressing the holding member 68 from one side in the second direction D2. The pressing member 69 has a base wall 69A, a through hole 69B penetrating the base wall 69A in the second direction D2, and an abutment portion 69C extending from the edge of the through hole 69B to the other side in the second direction D2. The wire enclosing portion 68A is inserted into the through hole 69B. The abutment portion 69C abuts against the plate-shaped portion 68B. As shown in FIGS. 1 and 3, the pressing member 69 also has a plurality of locking pieces 69D extending from the outer edge of the base wall 69A to the other side in the second direction D2. The locking pieces 69D are gate-shaped. A plurality of locking protrusions 67B protruding from the outer peripheral surface of the wire accommodating portion 67 are formed at one end of the wire accommodating portion 67 in the second direction D2. The pressing member 69 is assembled to the wire accommodating portion 67 by the locking protrusions 67B engaging with the locking pieces 69D.

[0045] As shown in FIG. 2, the cover 60 includes a lid 70 attached to the rear end of the cylindrical portion 61, a one-piece rubber stopper 71, and an attachment member 72. The lid 70 is made of insulating synthetic resin. The lid 70 includes a plate-shaped main body 70A, a partition 70B extending forward from the main body 70A, and a locking piece 70C extending forward from the outer edge of the main body 70A. As shown in FIG. 5, the main body 70A closes the rear opening of the cylindrical portion 61 from the rear. As shown in FIG. 8, the partition 70B is arranged to separate the relay terminal 51 and the core wire of the electric wire 50. As shown in FIG. 1, the locking piece 70C is gate-shaped. A plurality of locking protrusions 61B are formed on the outer surfaces of the cylindrical portion 61 and the electric wire accommodating portion 67. The cover 70 is assembled to the cylindrical portion 61 and the electric wire receiving portion 67 by the locking piece 70C and the locking projection 61B being engaged with each other.

[0046] As shown in Fig. 5, the main body 70A has an inner portion 70D disposed inside the cylindrical portion 61. An annular sealing member S2 is disposed between an outer peripheral surface 70D1 of the inner portion 70D and an inner peripheral surface 61A of the cylindrical portion 61. The sealing member S2 is made of an elastic material such as rubber. The sealing member S2 seals off water between the cylindrical portion 61 and the lid 70.

[0047] The cover 70 has an opening 70E penetrating the main body 70A in the front-rear direction. A one-piece rubber stopper 71 is disposed within the opening 70E. The outer circumferential surface of the one-piece rubber stopper 71 is in liquid-tight contact with the inner circumferential surface of the opening 70E. As shown in FIGS. 2 and 3, the one-piece rubber stopper 71 has a plurality of insertion holes 71A. Signal wires connected to signal terminals are inserted into the insertion holes 71A. This allows the signal wires to be led rearward from the cover 60. The inner circumferential surfaces of the insertion holes 71A are in liquid-tight contact with the outer circumferential surfaces of the signal wires. The mounting member 72 is made of insulating synthetic resin. As shown in FIGS. 3 and 5, the mounting member 72 is attached to the cover 70 while pressing the one-piece rubber stopper 71 from behind.

[0048] (Effects of the embodiment) (1) The charging connector 10 according to the embodiment is a charging connector 10 that mates with a mating connector in a first direction D1 (front-rear direction), and includes a housing 20, terminals 30 accommodated in the housing 20, electric wires 50 electrically connected to the terminals 30, and a cover 60 assembled to the housing 20. The cover 60 includes an electric wire guide portion 62 that guides the electric wire 50 in a second direction D2 intersecting the first direction D1 and holds the electric wire 50, and a lock portion 65 that is arranged at a position overlapping the electric wire guide portion 62 in the first direction D1. The housing 20 includes a lock receiving portion 27 that engages with the lock portion 65 in the first direction D1.

[0049] According to this configuration, the locking portion 65 of the cover 60 and the lock receiving portion 27 of the housing 20 are locked in the first direction D1, thereby suppressing rattling of the cover 60 relative to the housing 20. Therefore, displacement of the wire leading portion 62 provided in the cover 60 is suppressed, thereby suppressing vibration of the wire 50 relative to the housing 20. Furthermore, because the locking portion 65 is disposed at a position overlapping with the wire leading portion 62 in the first direction D1, an increase in size of the charging connector 10 can be suppressed.

[0050] (2) In the embodiment, the housing 20 has a housing main body 21 having an outer peripheral surface 26A that is circular when viewed in the first direction and in which the terminals 30 are arranged, the cover 60 has a cylindrical portion 61 having an inner peripheral surface 61A that is circular when viewed in the first direction and arranged on the outside of the housing main body 21, the locking portion 65 has a first portion 65A extending from the cylindrical portion 61 in the first direction D1 and a second portion 65B extending from the tip of the first portion 65A in a third direction D3 that is perpendicular to both the first direction D1 and the second direction D2, and the lock receiving portion 27 protrudes from the outer peripheral surface 26A of the housing main body 21.

[0051] With this configuration, by sliding the cylindrical portion 61 relative to the housing main body 21 so as to rotate it around the central axis of the cylindrical portion 61, the lock portion 65 and the lock receiving portion 27 can be easily engaged with each other.

[0052] (3) The charging connector 10 according to the embodiment further includes an annular sealing member S1 disposed between the housing body 21 and the cylindrical portion 61.

[0053] With this configuration, the gap between the housing 20 and the cover 60 can be sealed off.

[0054] (4) In the embodiment, it is preferable that the lock portion 65 be locked with the lock receiving portion 27 in the third direction D3 that is perpendicular to both the first direction D1 and the second direction D2.

[0055] With this configuration, the cover 60 can be positioned relative to the housing 20 in the third direction D3.

[0056] (Other embodiments) The above embodiment can be modified as follows: The above embodiment and the following modifications can be combined with each other within the scope of technical compatibility.

[0057] In the above embodiment, the second direction D2 is perpendicular to the first direction D1, but the second direction may intersect with the first direction. In other words, the direction in which the electric wires are drawn out does not have to be perpendicular to the mating direction of the charging connector and the mating connector, but may intersect with the mating direction.

[0058] In the above embodiment, the locking portion 65 has a protrusion 65C, the lock receiving portion 27 has a recess 27A that accommodates the protrusion 65C, and the locking portion 65 and the lock receiving portion 27 are configured to be engaged with each other in the third direction D3. However, the locking portion and the lock receiving portion of the present disclosure may be engaged only in the first direction without being engaged with each other in the third direction. The cover may be positioned relative to the housing in the third direction by, for example, bolt fastening.

[0059] The charging connector of the present disclosure does not need to include a signal terminal and a signal line.

[0060] In the above embodiment, the cover 60 includes the lid 70 that is separate from the cylindrical portion 61, but the cover of the present disclosure does not need to include a lid. For example, the cover may have a bottom wall that corresponds to the lid in the above embodiment and is integrally formed with the cylindrical portion. [Explanation of symbols]
