Japanese Patent Laid-Open No. 7-192826

  The charging connector is configured to include a terminal fitting connected to the terminal portion of the power line and a housing for accommodating the terminal fitting. However, at present, the terminal fitting can be displaced relative to the housing. There is a possibility that water enters the transformer side from the outside through the gap between the housing and the terminal fitting, and the infiltrated water may travel along the power line and reach the connection part with the electronic component. Since the conductor is exposed by removing the insulating coating at the connection portion of the power line with the electronic component, a waterproof measure is required to prevent the conductor from being exposed to water.

As a measure against waterproofing, a method of sealing the connection portion between the power line and the electronic component using a heat shrinkable tube or the like is conceivable. However, the method of individually sealing the connection portions as described above is inefficient because it takes time and labor when the connection portions are provided at a plurality of locations.
This invention is completed based on the above situations, Comprising: When a wire harness has a several waterproof object part, it aims at waterproofing efficiently.

  As means for achieving the above object, the invention of claim 1 is directed to a housing attached to a vehicle body, a plurality of terminal fittings attached to the housing, and connected to the terminal fittings to the rear side of the housing. A wire harness provided with a plurality of derived electric wires, and at least some of the electric wires are provided with a plurality of waterproof target portions with exposed conductors, and the waterproofing from the back of the housing in the wire harness A harness cover that encloses a range extending over the formation region of the target portion, and the harness cover faces the rear surface of the waterproof chamber that houses the plurality of waterproof target portions of the wire harness, and the drain port. The water guide chamber in which the water is formed, the waterproof chamber and the water guide chamber are partitioned in a liquid-tight manner, and the wire is penetrated in a liquid-tight manner. Characterized in place being constituted by a wall.

  According to a second aspect of the present invention, in the first aspect, the harness cover is configured by combining two half members, and the waterproof wall is sandwiched between the two half members. It is characterized in that it is provided with a sealing member that penetrates the electric wire in a liquid-tight state in a state where the electric wire is formed.

<Invention of Claim 1>
The water that has entered through the gap between the housing and the terminal fitting is guided into the water guide chamber and discharged from the drain outlet to the outside of the harness cover. Since the waterproof chamber in which the plurality of waterproof objects are accommodated is partitioned from the water guide chamber by the waterproof wall in a liquid-tight manner, water intrusion from the water guide chamber to the waterproof chamber is restricted. Thereby, the several waterproof object part in a waterproof room can be collectively waterproofed efficiently.

<Invention of Claim 2>
Since the harness cover has a form in which the half members are combined, the work of housing the wire harness in the harness cover is easy. Moreover, since the waterproof wall has a seal member that penetrates the electric wire in a liquid-tight manner, it is possible to reliably prevent water from entering the waterproof chamber from the water guiding chamber.

<Embodiment 1>
Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 1, the charging connector A of the present embodiment is provided on the vehicle body B, and the charging connector A is fitted with a power feeding connector (not shown) of the power feeding device. It has become so. When the power supply side connector is fitted to the charging connector A, an in-vehicle battery (not shown) can be charged.

  The charging connector A includes a housing 10, a plurality of terminal fittings 23 housed in the housing 10, a wire harness 24 led out from the housing 10, and a harness cover 50 that surrounds the wire harness 24. Yes. In the following description, for the sake of convenience, the direction in which the wire harness 24 is led out from the housing 10 (that is, the direction from the outside of the vehicle body B toward the inside of the vehicle body B) is referred to as “rear”.

  As shown in FIG. 1, the housing 10 is configured by assembling a terminal accommodating member 11 and a retainer 17. The terminal accommodating member 11 is made of a synthetic resin, and a cavity 12 of five chambers penetrating the terminal accommodating member 11 in the front-rear direction is formed in the terminal accommodating member 11. A rectangular flange portion 13 is formed on the outer periphery of the terminal accommodating member 11. A region behind the flange portion 13 in the terminal accommodating member 11 has a circular outer periphery, and a seal groove 14 is formed in the circular region. A seal ring 15 is attached to the seal groove 14. A plurality of lock protrusions 16 spaced apart in the circumferential direction are formed in a region behind the flange portion 13 on the outer periphery of the terminal accommodating member 11.

  The retainer 17 is made of synthetic resin and has a substantially circular rear wall 18 and a cantilever-like shape extending from the outer periphery of the rear wall 18 as shown in FIGS. 18 and five lock pieces 19 having a concentric arc shape. The lock pieces 19 are formed at intervals in the circumferential direction. The retainer 17 has a configuration in which the space between the adjacent lock pieces 19 and the recessed portion of the outer peripheral edge of the rear wall 18 are spaced apart in the circumferential direction and open to the outer peripheral edge and the front edge of the retainer 17. Five notches 20 are formed. Each lock piece 19 can be elastically displaced radially outward with the rear end edge (the outer peripheral edge of the rear wall 18) as a fulcrum. An arcuate locking rib 21 that protrudes radially outward is formed on the extended end edge (front end edge) of each lock piece 19. A lock hole 22 is formed in the lock piece 19 corresponding to the lock protrusion 16 among the five lock pieces 19.

  The retainer 17 is assembled so as to be fitted onto the housing 10 from the rear. During the assembly process, the lock piece 19 interferes with the lock protrusion 16 and is elastically displaced. When the retainer 17 is in a proper assembled state in which the rear surface wall 18 is in contact with the rear end surface of the housing 10, the lock piece 19 is elastically restored and the lock hole 22 and the lock projection 16 are locked. By this locking action, the retainer 17 is locked in the assembled state. In a state where the retainer 17 is assembled, the notch 20 of the retainer 17 corresponds to the opening of the cavity 12 on the rear end surface of the housing 10. Further, the locking rib 21 is located behind the seal groove 14.

  As shown in FIG. 1, terminal fittings 23 are inserted into the cavities 12 of the terminal accommodating member 11 from the rear (inside the vehicle). The electric wires 25 to 29 connected to the rear end portions in the insertion direction of the terminal fittings 23 are led out to the rear of the housing 10 (that is, inside the vehicle). The terminal fitting 23 can be relatively displaced in the front-rear direction in the cavity 12. Therefore, a clearance for allowing movement of the terminal fitting 23 is secured between the inner periphery of the cavity 12 and the outer periphery of the terminal fitting 23. Since the retainer 17 has a notch 20 extending from a portion corresponding to the cavity 12 to the outer peripheral edge of the retainer 17, assembly of the retainer 17 to the housing 10 and assembly of the terminal fitting 23 to the housing 10 are performed. Either of these may be done first.

  The housing 10 constituted by assembling the terminal fitting 23 and the retainer 17 as described above allows the terminal accommodating member 11 to pass through a hole (not shown) of the vehicle body B and bolts the flange portion 13 to the vehicle body B. It is fixed by that. In a state where the housing 10 is fixed to the vehicle body B, the front surface of the housing 10 faces the outside of the vehicle body B, and the front end portion of the housing 10 is a fitting portion (connecting portion) with the power feeding side connector. Further, as described above, since there is a clearance between the cavity 12 and the terminal fitting 23, when water adheres to the front surface of the housing 10 facing the outside of the vehicle body B, the water is transferred between the cavity 12 and the terminal fitting 23. It can enter the inside of the vehicle body B (the wire harness 24 side) through the gap.

  As shown in FIGS. 4 and 5, of the five electric wires 25 to 29 connected to the terminal fitting 23 and led out from the housing 10, three are electric wires having a large diameter, and two are radial dimensions. It is a small electric wire. Two of the three large-diameter electric wires 25 to 27 are high-voltage power lines 25 and 26 (hereinafter referred to as AC lines), and one is a ground wire 27 (hereinafter referred to as GND line). Moreover, the two small-diameter electric wires 28 and 29 are signal lines. These five electric wires 25 to 29 constitute a wire harness 24.

  As shown in FIG. 4, the wire harness 24 includes a signal line 30 and a signal line 31 connected to a PLC (Power Line Communication) unit (not shown) in addition to the five electric wires 25 to 29. .

Furthermore, the wire harness 24 also includes a transformer 32 including a ferrite core 33, electronic components 34, 35, 36 and a fuse 41.

  The transformer 32 includes a primary coil formed by winding the AC wires 25 and 26 around the ring-shaped ferrite core 33, and a secondary coil formed by winding the folded portion of the signal line 30 around the ferrite core 33. It is configured. The transformer 32 is for taking out a signal superimposed on the AC lines 25 and 26, and is disposed in the vicinity of the housing 10. The PLC unit extracts signals from the power feeding device by extracting signals superimposed on the AC lines 25 and 26 from the transformer 32, and is a circuit board (positioned away from the charging connector A). (Not shown). The fuse 41 is connected to the AC lines 25 and 26.

  A connection portion of the AC lines 25 and 26 with the electronic component 34, a connection portion of the AC lines 25 and 26 with the electronic component 35, a connection portion of the GND line 27 with the electronic components 35 and 36, and a signal line 31 of the GND line 27. At the connection portion, the sheath, the shield layer, and the insulating coating are removed, and the conductor 37 is exposed. Further, at the connection portion of the signal line 28 with the electronic component 36 and the connection portion of the signal line 31 with the signal line 27, the insulation coating is removed and the conductor 37 is exposed. In the exposed portions of these conductors 37, splice terminals 38 are used for connection by crimping. As shown in FIGS. 1 and 5, the plurality of connection portions are covered and hidden by winding a tape 39. However, since the conductor 37 exposed for connection cannot be waterproofed only by winding the tape 39, the plurality of connection portions are waterproof target portions 40 that are waterproofed by a harness cover 50 described later. . Further, the connection part between the AC wires 25 and 26 and the fuse 41 is also a waterproof target part 40. And the vicinity part of the waterproof object part 40 in the some waterproof object part 40 and the electric wires 25-31 is covered and covered by winding tape (illustration omitted) collectively.

  As shown in FIG. 1, the harness cover 50 includes a symmetric metal (copper alloy) lower cover 51 </ b> L (a half member that is a constituent of the present invention) and a symmetric metal (copper alloy) upper cover. 51U (half member which is a constituent element of the present invention), a pair of rubber-made symmetrical packings 68, a first seal member 69 made of rubber (a seal member which is a constituent element of the present invention), and rubber The second seal member 72 is assembled.

On the inner periphery of the arc-shaped wall portion 54, a locking groove 60 having a shape in which a region adjacent to the rear of the seal surface 59 is expanded in a concentric semicircular arc shape is formed. The partition wall 55 is formed with a first recess 61 that is notched in a semicircular arc concentric with the front chamber 52. The rear wall 58 is formed with a second recess 62 that is cut out in a semicircular arc concentric with the first recess 61. The lower cover 51L is formed with a pair of left and right projecting edges that project outward from the left and right side edges of the opening edge of the upper surface. A mounting groove 63 is formed that extends from the upper end surface of the lower cover 51 </ b> L to the region where the protruding edge is formed, the region where the partition wall 55 is formed, and the region where the rear wall 58 is formed.

  Three pairs of protrusions 64 are formed on the left and right overhanging edge portions so as to protrude from the outer surface thereof with a space therebetween in the front-rear direction. The three pairs of protrusions 64 include a position corresponding to the locking groove 60 (that is, a position close to the seal surface 59), a position corresponding to the partition wall 55 (first recess 61), and a rear wall 58 (second The recess 62) and the corresponding position are arranged. Each protrusion 64 is formed with a mounting hole 65 penetrating vertically. As shown in FIGS. 1 and 2, the lower cover 51 </ b> L is formed with a drain port 66 having a shape in which the lowermost position of the front chamber 52 is vertically penetrated. A drain hose 67 is connected to the drain port 66.

  The upper cover 51U has a halved configuration that is symmetrical with the lower cover 51L except that the drain port 66 is not formed. Accordingly, the same components are denoted by the same reference numerals as those of the lower cover 51L, and detailed description thereof is omitted. Further, the packing 68 is formed in the same shape as the mounting groove 63 and is elongated.

  As shown in FIGS. 1, 2, 4 and 5, the first seal member 69 has a thick disk shape and has five first seal holes 70 penetrating in the front-rear direction. On the outer periphery of the first seal member 69, a pair of front and rear enlarged diameter portions 71 projecting concentrically from the front end edge and the rear end edge are formed. In the first seal member 69, a portion of the five electric wires 25 to 29 led out from the housing 10 to the rear of the waterproof target portion 40 is inserted in a liquid-tight manner.

  As shown in FIGS. 1, 4, and 5, the second seal member 72 has a thick disk shape and has eight second seal holes 73 penetrating in the front-rear direction. On the outer periphery of the second seal member 72, a pair of front and rear diameter-expanding portions 74 projecting concentrically from the front edge and the rear edge is formed. Of the eight electric wires 25 to 31 constituting the wire harness 24, a portion behind the waterproof target portion 40 is inserted into the second seal member 72 in a liquid-tight manner.

  As shown in FIGS. 1 and 2, the lower cover 51 </ b> L and the upper cover 51 </ b> U are assembled by being combined vertically. At this time, the upper surface of the lower cover 51L where the mounting groove 63 is formed and the lower surface of the upper cover 51U where the mounting groove 63 is formed become the mating surfaces. The work of combining the covers 51L and 51U is performed simultaneously with the process of assembling the harness cover 50 to the housing 10. That is, when the lower cover 51L and the upper cover 51U are combined, the locking groove 60 is locked so as to be fitted on the locking rib 21 of the retainer 17, and the seal surface 59 is liquid-tight with respect to the seal ring 15.

The second seal member 72 is sandwiched between the second recesses 62 of the upper and lower rear wall portions 58 and is in close contact with the inner peripheral surface of the second recess 62 in a liquid-tight manner. The sandwiched second seal member 72 is restricted from relative displacement in the front-rear direction with respect to the rear wall portion 58 by sandwiching the rear wall portion 58 from the front and rear portions with both front and rear diameter enlarged portions 74.

  When the harness cover 50 is assembled and attached to the housing 10, water guide chambers 77 are formed in the harness cover 50 by the upper and lower front chambers 52 as shown in FIG. 1. Since the water guide chamber 77 faces the rear surface of the housing 10, the water that has adhered to the front end portion of the housing 10 and passed through the gap between the cavity 12 and the terminal fitting 23 is accommodated in the water guide chamber 77. The water that has entered the water guide chamber 77 is discharged from the drain port 66 through the drain hose 67 to the outside of the harness cover 50. Since the wire harness 24 is accommodated in the water guide chamber 77 only in a region in front of the waterproof target portion 40, even if water enters the water guide chamber 77, the wire harness 24 is not subjected to water. The resulting problem does not occur.

  As shown in FIGS. 1 and 2, a waterproof chamber 78 is formed in the harness cover 50 by the upper and lower rear chambers 53. Since the waterproof target part 40 of the wire harness 24 is accommodated in the waterproof chamber 78, the waterproof chamber 78 is provided with a waterproof measure for preventing inundation. That is, the waterproof chamber 78 and the water guide chamber 77 are partitioned in a liquid-tight manner by the waterproof wall 79 configured by the partition wall portion 55 and the first seal member 69. Further, the rear end portion of the waterproof chamber 78 is sealed by the second seal member 72 so as not to be immersed in the waterproof chamber 78 from the outside of the harness cover 50. A gap between the covers 51L and 51U is sealed by a packing 68 so as not to be submerged from the outside of the harness cover 50 into the waterproof chamber 78. Therefore, water does not adhere to the waterproof target portion 40 in the waterproof chamber 78.

  In the charging connector A of the present embodiment, at least a part of the electric wires 25 to 29 constituting the wire harness 24 led out to the rear (rear side) of the housing 10 has a plurality of insulation coatings surrounding the conductors removed. However, a range from the back surface of the housing 10 to a region where the waterproof target portion 40 is formed is surrounded by the harness cover 50.

  According to this configuration, the water that has entered through the gap between the housing 10 and the terminal fitting 23 is guided into the water guide chamber 77 and discharged from the drain port 66 to the outside of the harness cover 50. The waterproof chamber 78 in which the plurality of waterproof target portions 40 are accommodated is partitioned in a liquid-tight manner from the water guiding chamber 77 by the waterproof wall 79, so that the flooding from the water guiding chamber 77 to the waterproof chamber 78 is restricted. As described above, the charging connector A according to the present embodiment can collectively waterproof the plurality of waterproof target portions 40 in the waterproof chamber 78, so that it is more efficient than the case where the waterproof target portions 40 are individually waterproofed. It is.

  In addition, the harness cover 50 is configured by combining the lower cover 51L and the upper cover 51U, and the waterproof wall 79 passes through the electric wire in a liquid-tight manner while being sandwiched between the lower cover 51L and the upper cover 51U. One seal member 69 is provided. As described above, in the present embodiment, the harness cover 50 is formed by combining the lower cover 51L and the upper cover 51U in a halved form, so that the work of housing the wire harness 24 in the harness cover 50 is easy. Moreover, since the waterproof wall 79 has the 1st sealing member 69 which penetrates the electric wires 25-29 in a liquid-tight state, the water immersion from the water conveyance chamber 77 to the waterproof chamber 78 can be prevented reliably.

  Moreover, since the waterproof object part 40 and its vicinity of the wire harness 24 have removed the shield layer, the wire harness 24 itself has lost the shielding function, but in this embodiment, the waterproof object part 40 is Since the harness cover 50 to be accommodated is made of metal, the region of the wire harness 24 from which the shield layer is removed can be shielded.
