Description

  The present invention relates to a charging inlet for connecting a power supply plug.

  In recent years, with increasing awareness of environmental issues, plug-in hybrid vehicles, electric vehicles, and the like have been widely used as vehicles with low carbon dioxide emissions. In the case of these battery rechargeable vehicles, the battery is charged by connecting the power supply plug at the end of the charging cable extending from the charging facility to the charging inlet provided in the vehicle and turning on the power switch provided in the charging cable. (See Patent Document 1 etc.).

  When the power supply plug is used outdoors, it is assumed that water or the like adheres to it. If the wet power plug is inserted into the charging inlet during battery charging, water attached to the power plug may flow into the charging inlet and the electrical components of the charging inlet may get wet. In order to cope with this, a structure has been devised in which a drain hole is provided in the charging inlet, and water that has entered the inlet is discharged to the outside (see Patent Document 2, etc.).

A ground wire harness 27 and a pair of signal wire harnesses 28 are connected to the ground / signal vehicle body side female connector 20. The signal wire harness 28 is grounded by connecting the middle of the harness to the ground wire harness 27.

  As shown in FIGS. 3 and 4, the inlet main body 7 is formed as one component by integrally assembling a power plug fitting portion 8 and a vehicle body connector fitting portion 21 which are separate components. In the vehicle body connector fitting portion 21, a flange portion 29 protrudes from the circumferential edge along the end of the power supply plug fitting portion 8. On the outer periphery of the flange portion 29, a plurality of sets of lock module locking portions 30 including plate-like protrusions and arm-like claws are formed.

  As shown in FIGS. 3 to 5, the charging inlet 6 is provided with a plurality of terminals 31 to 35 as electrical terminals. In the case of this example, there are a pair of power terminals 31, 32, one ground terminal 33, and a pair of signal terminals 34, 35. In the terminals 31 to 35, the opening-side columnar distal end side terminal portions 31 a to 35 a serve as electrical connection locations with the power supply plug 5, and the base plate-like base end side terminal portions 31 b to 35 b are connected to the vehicle body connector 18. It becomes an electrical connection point. The terminals 31 to 35 correspond to inlet side terminals.

  Terminal mounting holes 36 to 40 through which the terminals 31 to 35 can be inserted and attached are formed through the seating surface 29 a of the flange portion 29. A pair of press-fitting pieces 41 are formed to protrude at substantially central positions of the terminals 31 to 35 on both sides in a direction perpendicular to the longitudinal direction of the terminals 31 to 35. The terminals 31 to 35 are fixed by press-fitting a pair of press-fitting pieces 41 into narrow portions at both ends of the terminal mounting holes 36 to 40.

  As shown in FIGS. 5, 7, and 8, the distal end side terminal portions 31 a to 35 a are inserted into through holes 9 a to 13 a penetrating the bottom walls of the terminal insertion holes 9 to 13, thereby Each is exposed in insertion holes 9-13. The base end side terminal portions 31b to 35b are respectively exposed in the terminal insertion holes 24 and 25 by being inserted into the small diameter holes 36a to 40a at the back of the terminal mounting holes 36 to 40. As shown in FIG. 5, when the charging inlet 6 is assembled to the vehicle body, the power supply plug fitting portion 8 is exposed to the power supply port 3, and the vehicle body connector fitting portion 21 is incorporated inside the vehicle body 1.

  As shown in FIGS. 4 and 5, the terminals 31 to 35 are inserted into the terminal mounting holes 36 to 40 via ring-shaped seal members 42 to 46. The seal members 42 to 46 have a function of preventing water from entering from the power plug fitting portion 8 to the vehicle body connector fitting portion 21 and are made of, for example, a resin (rubber) packing. As shown in FIG. 5, the seal members 42 to 46 are attached to an intermediate width seal attachment portion 47 located substantially at the center of the base end side terminal portions 31 b to 35 b, and are located at the back in the terminal attachment holes 36 to 40. Is arranged. The sealing members 42 to 46 are positioned and fixed in the terminal mounting holes 36 to 40 by press-fitting and fixing the terminals 31 to 35 (press-fitting pieces 41).

  As shown in FIGS. 6 to 8, the charging inlet 6 (power supply plug fitting portion 8) has water that has entered the terminal insertion holes 9 to 13 in the outer direction (the direction of the white arrow in FIG. 8). The main drainage portions 48 to 52 are formed so as to be drawn out and discharged to the outside of the hole. The main drainage portions 48 to 52 are formed at the back position (the end portion in the + axis direction in FIG. 7) of the power plug fitting portion 8. Therefore, as shown in FIG.6 and FIG.7, the main water draining parts 48-52 extract water outside in the contact | abutting surface of the terminal insertion holes 9-13.

  As shown in FIG. 9, the main drainage portions 48 to 52 are formed by extending the water dropping hole 53 serving as a main path for water discharge and the water dropping hole 53 upward in the outer periphery of the charging inlet 6. It is defined as a hole having a water film cutting hole 54. By the way, this type of drain hole has a characteristic that a water film is not stretched in the hole unless water is applied to the whole hole, and water does not easily accumulate. Therefore, if the water dropping hole 53 formed as a normal drain hole is extended in the circumferential direction, that is, if the water film cutting hole 54 is extended, it becomes difficult for water to be applied to the hole. Thereby, it becomes difficult for water to stick to the main drainage parts 48 to 52, and high drainage is ensured.

  As shown in FIGS. 7 and 8, water guide walls 48 a to 52 a are formed in the main drainage portions 48 to 52 as main paths through which water flows. The water guide walls 48 a to 52 a are defined as one path of the water dropping hole 53. The water drop hole 53 is also a hole whose hole outlet is located vertically below the center P of the terminal insertion hole 9 (10-13). The center P of the hole coincides with the axis of the terminals 31 to 35.

  Further, passage walls 48b to 52b are formed in the main drainage portions 48 to 52 at positions facing the water guide walls 48a to 52a. The passage walls 48 b to 52 b are defined as one path of the water film cut hole 54. Further, the passage walls 48b to 52b are walls extending in parallel in the horizontal direction, and work so that a water film does not stretch on the main drainage portions 48 to 52. The water guide walls 48a to 52a and the passage walls 48b to 52b form substantially tapered holes in the main drainage portions 48 to 52.

  As shown in FIG. 10, the opening angle θ of the main drainage portions 48 to 52 (FIG. 10 shows only the drainage hole 48) is formed to be at least 90 degrees. As for the opening angle θ of the hole, assuming that the center P of the terminal insertion hole 9 is the apex, the straight line connecting the apex to the root M1 of the water guide wall 48a is La, and the straight line connecting the apex to the root M2 of the passage wall 48b is Lb. , Corresponding to the angle formed by the straight lines La and Lb. The main drainage portions 49 to 52 are also set to the same opening angle θ. It was confirmed that when the opening angle θ of the hole is 90 degrees, it is difficult for water to stick to the hole.

  As shown in FIGS. 11 and 12, the charging inlet 6 is provided with an auxiliary draining portion 55 that drains the water in the charging inlet 6 to the outside at a position deeper than the main draining portions 48 to 52. This is because there is a clearance in the assembly portion between the terminals 31 to 35 and the through holes 9a to 13a, so water that cannot be removed by the main drainage portions 48 to 52 reduces the clearance of the through holes 9a to 13a. Therefore, an auxiliary drainage portion 55 is provided in the further depth of the main drainage portions 48 to 52, and the water that has entered the depth is discharged to the outside of the inlet. Therefore, the charging inlet 6 of this example can discharge the water in the inlet to the outside by a two-stage draining structure.

  The auxiliary water draining portion 55 is provided with five storage chambers 56 to 60 for storing the terminals 31 to 35. The storage chambers 56 to 60 are a third storage chamber in which the first storage chamber 56 and the second storage chamber 57 that store the power terminals 31 and 32 are arranged at the top in the vertical direction, and the signal terminals 34 and 35 are stored. 58 and the fourth storage chamber 59 are disposed in the middle, and the fifth storage chamber 60 for housing the grounding terminal 33 is disposed at the bottom. The storage chambers 56 to 60 are formed by being partitioned into a substantially annular outer peripheral wall 61 and four partition walls 62 to 65.

  A first communication hole 66 that connects the first storage chamber 56 and the third storage chamber 58 is formed between the outer peripheral wall 61 and the first partition wall 62. A second communication hole 67 that connects the second storage chamber 57 and the fourth storage chamber 59 is formed between the outer peripheral wall 61 and the second partition wall 63. A third communication hole 68 that connects the third storage chamber 58 and the fifth storage chamber 60 is formed between the outer peripheral wall 61 and the third partition wall 64. A fourth communication hole 69 that connects the fourth storage chamber 59 and the fifth storage chamber 60 is formed between the outer peripheral wall 61 and the fourth partition wall 65. At the lower end in the vertical direction of the outer peripheral wall 61, the water flowing through the first communication hole 66 → the third communication hole 68 and the water flowing through the second communication hole 67 → the fourth communication hole 69 are placed outside the inlet. A water dropping hole 70 for discharging is formed.

  As shown in FIG. 13, at the lower part of the abutting surface of the lock module 14, the first drain hole 71 that drains the water that flows out from the main drainage portions 48 to 52 to the outside, and the water that flows out from the auxiliary drainage portion 55. And a second discharge hole 72 for discharging the gas to the outside. The second discharge hole 72 is disposed deeper in the axial direction than the first discharge hole 71. The first discharge hole 71 and the second discharge hole 72 discharge water to the outside of the inner wall of the vehicle body.

  As shown in FIG. 14, on the surface of each of the water guide walls 48a, 49a of the main drainage portions 48, 49, a water suction portion 73 (FIG. 14 shows the main drainage portion 49 side) that sucks out a water film stretched in the hole. Are shown). The water sucking portion 73 is formed by a groove extending in the vertical direction in the inclined water guide walls 48a and 49b. The water sucking portion 73 works to draw water stretched in the hole by a groove extending in the vertical direction, and makes it difficult to form a water film in the hole. The water suction part 73 may also be formed in the main water drain parts 51 and 52.

Next, the operation of the main drainage portions 48 to 52 and the auxiliary drainage portion 55 of this example will be described with reference to FIGS. 6, 8, 12, and 13.
As shown in FIG. 8, when the power supply plug 5 to which water or the like is attached is connected to the power supply plug fitting portion 8, it is assumed that the water flows into the terminal insertion holes 9 to 13. The water flowing into the grounding terminal insertion hole 11 is caused to flow directly under the main water draining part 50 and discharged to the outside of the power supply plug fitting part 8. Further, the water flowing into the terminal insertion holes 9, 10, 12, 13 is caused to flow laterally by the main drainage portions 48, 49, 51, 52 and discharged outside the inlet.

  As shown in FIG. 6, the water discharged from the main drainage portions 48, 49, 51, 52 falls along the outer peripheral surface of the power supply plug fitting portion 8 due to its own weight. And as shown in FIG. 13, the water discharged | emitted from the main water drain parts 48-52 is finally discharged | emitted from the 1st discharge hole 71 of the lock module 14 outside an inlet. The water discharged from the first discharge hole 71 is dropped to the outside of the inner wall of the vehicle body, for example, the outside of the vehicle or a gap between the panel portion 4 and the inner wall of the vehicle body.

  In the case of this example, the main drainage portions 48 to 52 are not simply holes having the shape of the water dropping hole 53, but are cut out in the vertical direction to the water dropping hole 53 to extend the water film cutting hole. The hole shape which has 54 is taken. For this reason, since it becomes possible to make the hole structure of the main drainage parts 48-52 into a hole in which water is hard to stick to a hole, water is smoothly discharged from the main drainage parts 48-52.

  The water that has flowed into the terminal insertion holes 9 to 13 passes from the through holes 9a to 13a, which are assembling portions of the terminals 31 to 35, into the back of the power supply plug fitting portion 8, that is, the first storage chamber 56 to the fifth storage chamber 60. May flow in. In this case, as shown in FIG. 12, the water flowing into the first storage chamber 56 flows into the third storage chamber 58 through the first communication hole 66, and the water in the third storage chamber 58 passes through the third communication hole 68. Then, it is discharged from the water dropping hole 70 to the outside of the power supply plug fitting portion 8. Further, the water flowing into the second storage chamber 57 flows into the fourth storage chamber 59 through the second communication hole 67, and the water in the fourth storage chamber 59 passes through the fourth communication hole 69 and passes through the water drop hole 70 to the power plug. It is discharged outside the fitting portion 8.

  As shown in FIG. 13, the water discharged from the auxiliary drain part 55 (water dropping hole 70) is discharged from the second discharge hole 72 of the lock module 14 to the outside of the inlet. The water discharged from the second discharge hole 72 is dropped to the outside of the inner wall of the vehicle body, for example, the outside of the vehicle or the gap between the panel portion 4 and the inner wall of the vehicle body.

According to the configuration of the present embodiment, the following effects can be obtained.
(1) Since the main water drainage portions 48 to 52 for flowing water flowing into the terminal insertion holes 9 to 13 toward the outside of the power supply plug fitting portion 8 and discharging the water to the outside of the power supply plug fitting portion 8 are provided. Inflow water can be made difficult to reach the terminal insertion holes 24 and 25 of the vehicle body connector fitting portion 21. Therefore, in the case of the direct connection type charging inlet 6, since the vehicle body connector fitting portion 21 is integrally formed with the power supply plug fitting portion 8, a structure for preventing water from being applied to the vehicle body connector fitting portion 21 is required. Can be dealt with.

  (2) Since the water film cut hole 54 is formed by extending the hole in the water drop hole 53 on the upper side in the circumferential direction, it is difficult for water to be applied to the main drainage portions 48 to 52. Therefore, the high drainage of the main drainage parts 48-52 is securable.

  (3) Since the main drainage portions 48 to 52 are arranged on the axial abutting surfaces of the terminal insertion holes 9 to 13, the water flowing into the terminal insertion holes 9 to 13 is brought to the abutting surface of the power supply plug fitting portion 8. It can be collected and discharged outside the inlet. Therefore, an effect becomes high in ensuring high drainage of the main drainage parts 48-52.

  (4) The auxiliary drainage part 55 was provided in the back | inner position of the main drainage parts 48-52, and it was set as the two-stage drainage structure. For this reason, even if water flows into the back through the clearances of the through holes 9a to 13a of the assembled portions of the terminals 31 to 35, this can be discharged from the auxiliary drain portion 55 to the outside of the inlet. Accordingly, the effect of preventing the vehicle body connector fitting portion 21 from getting wet is further enhanced.

  (5) The water that has flowed into the terminal insertion holes 9 to 13 is discharged to the outside of the inlet from the main drainage portions 48 to 52 and the auxiliary drainage portion 55 located outside the inner wall of the vehicle body. Therefore, the water flowing into the terminal insertion holes 9 to 13 does not have to flow into the inside of the vehicle body inner wall, that is, the inside of the vehicle body 1, so that the effect of preventing the vehicle body connector fitting portion 21 from getting wet is further enhanced.

  (6) Since the water suction portion 73 is provided on the water guide walls 48a and 49a of the main drain portions 48 and 49, it is possible to make it difficult to water the main drain portions 48 and 49. Therefore, the effect of securing high drainage of the main drainage portions 48 and 49 is enhanced.

  (7) Since the first discharge hole 71 and the second discharge hole 72 are provided in the lock module 14, the water discharged from the main drainage portions 48 to 52 and the auxiliary drainage portion 55 is discharged from the first discharge hole 71 and the second drainage hole 55. 2 from the discharge hole 72 to the outside of the lock module 14. Therefore, water does not collect in the lock module 14.

  (8) Since the seal members 42 to 46 are attached to the terminals 31 to 35, it is possible to make it difficult for water that has flowed into the power plug fitting portion 8 to reach the terminal insertion holes 24 and 25. Accordingly, the effect of preventing the vehicle body connector fitting portion 21 from getting wet is further enhanced.
