This connector assembly includes an external sub-assembly extending in a front-rear direction, an internal sub-assembly disposed in the external sub-assembly and receiving a terminal, a cable connected to the terminal and extending rearward, a cable seal to be mounted to cover a rear opening of the external sub-assembly, and a retainer to be mounted on the external sub-assembly from behind.Further connectors with a retaining device are known from the post-published publications DE 10 2019 003 228 A1, DE 10 2019 003 230 A1 and DE 10 2019 003 231 A1.Specifically, DE 10 2019 003 228 A1 discloses a connector comprising: a housing including an opening through which a wire is to be inserted; and a retainer to be mounted on the housing including at least one locking lance arranged to be substantially directed to the wire and resiliently displaceable in a direction toward the wire and configured to hold the wire by the locking lance resiliently contacting the wire. The locking lance has at least one curved portion having a curved shape substantially in accordance with an outer circumferential surface of the wire, and includes one or more protrusions that project(s) in a direction opposite to the one direction from the curved portion in a curved direction. The housing includes at least one pressing portion configured to resiliently displace the curved portion in the one direction and bring the curved portion into surface contact with the outer circumferential surface of the wire by pressing the pair of protrusions in the one direction.Document DE 10 2019 003 230 A1 discloses a connector comprising: a housing including an opening open toward an opening side; a seal ring configured to prevent entry of a liquid into the housing from the opening side by being at least partially inserted into the opening and resiliently contacting an inner peripheral surface of the opening; and a retainer including at least one contact portion configured to come into contact with the seal ring, wherein the retainer is configured to hold the seal ring in the housing through the contact portion(s) that(s) come into contact with the seal ring. The retainer is mounted to the housing to substantially cover the opening of the housing. At least one drainage port configured to discharge a liquid that has entered the retainer and adheres to the seal ring to the outside is open in an inner wall of the retainer (16).Document DE 10 2019 003 231 A1 discloses a connector comprising: a housing including an opening into which a wire is to be at least partially inserted; and a retainer to be mounted on the housing from the opening side, the retainer including at least one locking lance arranged to be substantially directed to the wire and resiliently displaceable substantially toward the wire, the retainer holding the wire by the locking lance resiliently contacting the wire. The housing includes at least one protruding pressing portion, the pressing portion resiliently displaces the locking lance substantially toward the wire to resiliently bring the locking lance into contact with the wire by pressing the locking lance substantially in a direction toward the wire; and the retainer includes at least one displacement preventing portion configured to prevent displacement of the pressing portion in a direction substantially opposite to a contacting direction with the locking lance by contacting the pressing portion substantially in the direction toward the wire.SUMMARY OF THE INVENTIONTechnical ProblemHowever, there is a possibility that water enters the connector from behind the connector and directly wets the cable seal. In particular, when a water pressure is high, such as during washing, there is a problem that the sealability of the cable seal cannot be sufficiently secured.Solution to the ProblemAccording to a first aspect of the present invention, the underlying problem is solved by a connector including a housing provided with an opening that is open rearward, a wire extending rearward from the opening, a locking lance facing the wire, the locking lance being resiliently displaceable toward the wire, and a retainer mounted on the housing from a side of the opening, the retainer retaining the wire by the locking lance resiliently contacting the wire, the housing including a pressing portion protruding rearward from the opening, and the pressing portion resiliently displacing the locking lance toward the wire, In order to resiliently bring the locking lance into contact with the wire by pressing the locking lance toward the wire, the retainer includes a plate-like base end wall configured to come into contact with an opening edge of the opening from behind, a first insertion hole and a second insertion hole open in the base end wall, the wire being inserted into the first insertion hole, the pressing portion being inserted into the second insertion hole, and a water wetting suppressing wall disposed behind the second insertion hole, the water wetting suppressing wall suppressing water penetration into the opening through the second insertion hole, and the water wetting suppressing wall having a region, which overlaps an interior of an opening of the second insertion hole when viewed from behind.Since the water wetting suppressing wall has the region that overlaps the inside of the opening of the second insertion hole when viewed from behind, direct penetration of water into the opening through the second insertion hole is suppressed by the water contacting the water wetting suppressing wall when the retainer is wetted with water from behind the retainer.Further, the locking lance is provided to protrude rearward from the base end wall, and the water wetting suppressing wall is provided to protrude from a rear end part of the locking lance in a direction away from the wire and overlap a region in the opening of the second insertion hole when viewed from behind. The portion extends from a first opening edge of the opening of the second insertion hole to a second opening edge of the opening of the second insertion hole. The first opening edge is arranged on a first side of the second insertion hole facing the wire, and the second opening edge is arranged on a second side of the second insertion hole opposite the first side.Since the water wetting suppressing wall overlaps the range from the opening edge of the second insertion hole on the side toward the wire to the opening edge of the second insertion hole on the side opposite to the side toward the wire when viewed from behind, it is possible to suppress water from entering the opening of the housing through a clearance between the water wetting suppressing wall and the opening edge of the second insertion hole on the side toward the wire and a clearance between the water wetting suppressing wall and the opening edge of the second insertion hole on the side opposite to the side toward the wire.Further, the locking lance includes a curved portion having a curved shape in accordance with an outer circumferential surface of the wire, and the curved portion is provided with a slot extending in an extending direction of the wire, wherein the water wetting suppressing wall is composed of a pair of individual water wetting suppressing walls, and the individual water wetting suppressing walls are provided to protrude from a rear end part of the curved portion in the direction away from the wire.The curved portion is divided by providing the slit in the curved portion, whereby the curved portion can be easily deflected. By providing the individual water wetting suppressing wall on each of parts of the curved portion divided by the slit, the area overlapping the inside of the opening of the second insertion hole can be made wider when viewed from behind, compared to a configuration in which the individual water wetting suppressing wall is provided on one of the divided parts.A single water wetting suppression wall coupling portion that couples mutually facing side surfaces of the pair of single water wetting suppression walls is provided between the pair of single water wetting suppression walls.By providing the individual water wetting suppressing wall coupling portion, intrusion of water into the second insertion hole through a clearance between the pair of individual water wetting suppressing walls can be suppressed.According to another aspect of the present invention, the underlying problem is solved by a connector comprising: a housing including an opening into which a wire is inserted; and a retainer mounted on a side of the housing into which side the wire is inserted, wherein the retainer retains the wire. The retainer includes a first insertion hole into which the wire is inserted; and a second insertion hole. The housing includes a pressing portion for applying a pressing force for holding the wire inserted into the first insertion hole to the retainer when the pressing portion is inserted into the second insertion hole. The retainer includes a water wetting suppression wall that overlaps at least a part of the second insertion hole when viewed from behind. The retainer retains the wire via a locking lance. The retainer and the locking lance are integrally molded. The second insertion hole is a hole formed by a mold for molding the retainer and the locking lance.Effect of the InventionAccording to the connector disclosed in this specification, it is possible to provide a connector that suppresses direct water wetting of a seal ring.BRIEF DESCRIPTION OF THE DRAWINGFIG. 1 is a front perspective view of a connector in an embodiment, FIG. 2 is a rear perspective view of the connector before a retainer is mounted, FIG. 3 is a front perspective view of the connector before the retainer is mounted, FIG. 4 is a plan view of the connector, FIG. 5 is a rear view of the connector, FIG. 6 is a sectional view taken along A-A in FIG. 5 , FIG. 7 is a rear view of the retainer, FIG. 8 is a front view of the retainer; and FIG. 9 is an enlarged view near the retainer in FIG. 2.Embodiment of the Invention<>An embodiment will be described with reference to FIGS. 1, 2, 3, 4, 5, 6, 7, 8 to 9. In the following description, an X direction, a Y direction, and a Z direction in FIGS. 1, 2, 3, 4, 5, 6, 7, 8 to 9 are referred to as a forward direction, a rightward direction, and an upward direction.The connector 10 of this embodiment includes a housing 12 to be connected to a mating connector (not shown) and a retainer 16 to be mounted on the housing 12 from behind, as shown in FIG. 1.As shown in FIG. 1, the housing 12 is composed of a terminal accommodating portion 18 having a tubular shape long in a front-rear direction, and a housing-side receptacle 20 provided on the outer periphery of a front part of the terminal accommodating portion 18 and open forward. A pair of left and right cavities 22 in the form of rectangular tubes are provided in the terminal accommodating portion 18, and terminals are accommodated in the pair of left and right cavities 22, respectively.As shown in FIG. 2, the terminal receiving portion 18 is provided with an opening 24 that is open rearward, and a multi-core cable 14 in which two covered wires (not shown) are bundled and covered with an outer covering is inserted into the opening 24. Cores (not shown) of the two covered wires of the cable 14 are electrically connected to the terminals in the pair of cavities 22, respectively.As shown in FIG. 6, a seal ring 28 is inserted on the cable 14 and accommodated in the opening 24. The outer peripheral surface of the seal ring 28 is resiliently in contact with an inner peripheral surface 29 of the opening 24 of the terminal accommodating portion 18, and the inner peripheral surface of the seal ring 28 is resiliently in contact with an outer peripheral surface 30 of the cable 14. A front contact wall 32 configured to come into contact with the front surface of the seal ring 28 is provided in the terminal accommodating portion 18, thereby preventing the seal ring 28 from being displaced forward in the terminal accommodating portion 18.As shown in FIGS. 2 and 3, a pair of housing-side locking portions 34 for preventing the retainer 16 to be described later from leaking rearward are each provided to protrude outward on both side surfaces of the terminal accommodating portion 18. Further, the terminal receiving portion 18 is provided with a pair of upper and lower pressing portions 36 which respectively project rearward from an opening edge at the upper end and an opening edge at the lower end of the opening 24.Of the pair of upper and lower pressing portions 36, the upper pressing portion 36 is composed of a pair of left and right individual pressing portions 38 projecting rearward from the opening edge at the upper end of the opening 24, and the pair of left and right individual pressing portions 38 are located at a predetermined interval in a lateral direction as shown in FIG. 2. Similar to the upper pressing portion 36, the lower pressing portion 36 is composed of a pair of left and right single pressing portions 38 projecting rearward from the opening edge at the lower end of the opening 24.The retainer 16 is a retainer for holding the cable 14 and the seal ring 28 in the housing 12 and includes, as shown in FIG. 9, a base end wall 40 in the shape of an elliptical plate that is long in the lateral direction, a retainer-side receptacle 42 that is open forward from the outer peripheral edge of the base end wall 40, and a frame portion 46 that has a frame shape and protrudes rearward from the rear surface of the base end wall 40. The retainer 16 is integrally molded with a pair of upper and lower locking lances 44 projecting rearward from the rear surface of the base end wall 40. As shown in FIG. 1, the retainer 16 is mounted on the housing 12 such that the retainer-side receptacle 42 covers the opening 24 of the terminal accommodating portion 18. As shown in FIG. 8, a first insertion hole 48 into which the cable 14 is inserted is provided to be open at a center of the base end wall 40, and a pair of upper and lower second insertion holes 50 into which the pair of upper and lower pressing portions 36 are inserted respectively and which are provided above and below the first insertion hole 48 respectively are provided to be open in the base end wall 40. The pair of upper and lower second insertion holes 50 are holes formed by a mold for molding the retainer 16 and the pair of upper and lower locking lances 44.As shown in FIG. 3, two first slits 52 cut in the front-rear direction are provided at a predetermined interval in a vertical direction in each of both side surfaces of the retainer-side receiver 42, thereby forming a pair of left and right lock arms 54 resiliently displaceable in the lateral direction. The pair of lock arms 54 have openings long in the front-rear direction in vertical centers, and front end parts of the opening edges of these openings serve as retainer-side lock portions 58.When the retainer 16 is mounted on the housing 12, the retainer-side locking portions 58 can come into contact with the housing-side locking portions 34 from the front, and the retainer 16 is prevented from being separated rearward from the housing 12.As shown in FIG. 9, the pair of upper and lower locking lances 44 are protruded rearward (in an extending direction of the cable 14) from the opening edge of the first insertion hole 48 of the base end wall 40.The retainer 16 holds the cable 14 via the pair of upper and lower locking lances 44. As shown in FIGS. 8 and 9, the upper locking lance 44 includes a curved portion 60, a water wetting suppression wall 62, and a pair of left and right protrusions 64.As shown in FIG. 9, the curved portion 60 is provided to extend rearward (in the extending direction of the cable 14) from the opening edge of the first insertion hole 48, and has a curved shape in accordance with the outer circumferential surface 30 of the cable 14. As shown in FIGS. 8 and 9, the pair of left and right protrusions 64 is provided in front of the water wetting suppression wall 62, and are each provided to protrude upward from both end sides in the lateral direction (curving direction) of the curved portion 60. As shown in FIG. 9, tapered surfaces 66 inclined forward toward the upper surface of the curved portion 60 are provided on upper end parts of the pair of protrusions 64. Further, the lower surface of the curved portion 60 serves as a saw-tooth-like portion 68 having a saw-tooth shape. When the cable 14 is held in the housing 12, the saw-tooth-like portion 68 bites into the cable 14, thus improving a holding force of the cable 14. Further, since the curved portion 60 extends in the extending direction of the cable 14, a contact area of the saw-tooth-like portion 68 and the cable 14 is large and the holding force of the cable 14 is improved.As shown in FIGS. 7 and 9, a second slot 70 cut in the front-rear direction (extending direction of the cable 14) is provided in a center between a pair of left and right individual water wetting suppressing walls 88 (and the pair of left and right protrusions 64) provided on a rear end part of the curved portion 60, thereby dividing the curved portion 60 into left and right parts.The water wetting suppressing wall 62 is composed of the pair of left and right individual water wetting suppressing walls 88 as shown in FIG. 9, and the pair of left and right individual water wetting suppressing walls 88 are each provided to protrude upward from the rear end part of the curved portion 60. Of the pair of left and right single water wetting suppressing walls 88, the left single water wetting suppressing wall 88 is disposed to the left of the second slot 70, and the right single water wetting suppressing wall 88 is disposed to the right of the second slot 70. A single water wetting suppression coupling portion 90 is provided between the pair of left and right single water wetting suppression walls 88, and the single water wetting suppression wall coupling portion 90 is connected to each of mutually facing side surfaces of the pair of left and right single water wetting suppression walls 88.The pair of left and right single water wetting suppressing walls 88 are provided in regions that overlap the inside of the second insertion hole 50 when viewed from behind as shown in FIG. 7, and overlap a region of the second insertion hole 50 from an opening edge at the upper end to an opening edge at the lower end as shown in FIG. 8. Further, the single water wetting suppression wall coupling portion 90 overlaps the inside of the opening of the second insertion hole 50 when viewed from behind.Since the protrusions 64 are accommodated in the opening of the second insertion hole 50, as shown in FIG. 8, water can enter the opening 24 through clearances between the protrusions 64 and the opening edge of the second insertion hole 50, and the seal ring 28 can be directly wetted with water when the water wetting suppression wall 62 is not provided. However, since the pair of individual water wetting suppression walls 88 and the individual water wetting suppression wall coupling portion 90 are provided at positions overlapping the inside of the second insertion hole 50, when viewed from behind, water that attempts to enter the second insertion hole 50 contacts the pair of individual water wetting suppression walls 88 and the individual water wetting suppression wall coupling portion 90.Of the pair of upper and lower locking lances 44, the lower locking lance 44 has a vertically symmetrical shape with the upper locking lance 44 and has the same configuration as the upper locking lance 44 in other points as shown in FIG. 7.As shown in FIG. 9, the frame portion 46 is composed of a pair of upper and lower displacement preventing portions 72 respectively projecting rearward from upper and lower end parts of the base end wall 40, and a pair of left and right coupling portions 74 respectively coupling both left and right end parts of the pair of upper and lower displacement preventing portions 72. The pair of upper and lower coupling portions 74 are provided with a pair of left and right protruding portions 76 which protrude laterally inward from the frame portion 46 from surfaces facing each other. The pair of left and right protruding portions 76 are each in contact with the cable 14 in the lateral direction as shown in FIG. 5, thereby restricting lateral displacement of the cable 14.When the retainer 16 is mounted on the housing 12, the pair of upper and lower pressing portions 36 of the housing 12 is inserted between the pair of upper and lower displacement preventing portions 72 of the retainer 16 and the protrusions 64 of the pair of upper and lower locking lances 44, as shown in FIG. 6. The pairs of left and right single pressing portions 38 of the pressing portions 36 individually press the pairs of left and right protrusions 64 toward the cable 14 in directions of the locking lances 44, respectively. in this way, the locking lances 44 are resiliently displaced toward the cable 14, and the saw-tooth portions 68 of the curved portions 60 of the locking lances 44 resiliently contact the cable 14, further, the locking lances 44 are resiliently displaced in directions opposite to the directions toward the cable 14 by a reaction force of the cable 14 generated due to the resilient contact of the locking lance 44 with the cable 14. In this way, the pairs of left and right individual pressing portions 38 are displaced in the directions opposite to the directions toward the cable 14, and resiliently contact the displacement preventing portions 72 from the directions opposite to the directions toward the cable 14.When the retainer 16 is mounted on the housing 12, the opening edge of the first insertion hole 48 of the base end wall 40 comes into contact with the seal ring 28 from behind as shown in FIG. 6 to prevent the seal ring 28 from leaking rearward, and a part of the opening edge of the first insertion hole 48 coming into contact with the seal ring 28 from behind serves as a contact portion 86.Next, functions of this embodiment will be described.It is assumed that the retainer 16 is wetted with water drops from behind the retainer 16. At this time, the water drops flying toward the second insertion hole 50 contact the pair of individual water wetting suppressing walls 88 provided in front of the second insertion hole 50, and the penetration of the water drops into the opening 24 is suppressed through the second insertion hole 50. Further, even if the water drops get to enter through the clearance between the pair of individual water wetting suppressing walls 88, the water drops are suppressed from entering the opening 24 through the second insertion hole 50, because the water drops contact the individual water wetting suppressing wall coupling portion 90 provided between the pair of individual water wetting suppressing walls 88.As described above, according to this embodiment, the water wetting suppression wall 62 has a region that overlaps the inside of the second insertion hole 50 when viewed from behind. Thus, when the retainer 16 is wetted with water from behind the retainer 16, direct penetration of the water into the opening 24 through the second insertion hole 50 is suppressed because the water contacts the water wetting suppression wall 62.Further, since the water wetting suppressing wall 62 covers the second insertion hole 50 between the opening edge on a side toward the cable (wire) 14 and the opening edge on a side opposite to the side toward the cable (wire) 14, when viewed from behind, it is possible to suppress water from entering the opening 24 of the housing 12 through a clearance between the water wetting suppressing wall 62 and the opening edge of the second insertion hole 50 on the side toward the cable (wire) 14 and a clearance between the water wetting suppressing wall 62 and the opening edge on the side of the second insertion hole 50 opposite to the side toward the cable (wire) 14.Further, the curved portion 60 is divided by providing the second slot (slot) 70 in the curved portion 60, whereby the curved portion 60 can be easily deflected. By providing the single water wetting suppressing wall 88 on each of the parts of the curved portion 60 divided by the second slit (slit) 70, the area overlapping the inside of the second insertion hole 50 can be made wider when viewed from behind, compared to a configuration in which the single water wetting suppressing wall 88 is provided only on one of the divided parts.Further, water entering the second insertion hole 50 through the clearance between the pair of individual water wetting suppression walls 88 can be suppressed by providing the individual water wetting suppression wall coupling portion 90.< Embodiments>The technique disclosed by this specification is not limited to the embodiment described and illustrated above. For example, the following various types are also included. (1) Although the pair of upper and lower locking lances 44 of the retainer 16 resiliently contact the cable 14 from an upper and lower side, respectively, to retain the cable 14 in the housing 12 in the above embodiment, a pair of left and right locking lances may be provided and resiliently contact a cable from a left and right side. Further, a locking lance may be provided and resiliently contacting a cable from one side to retain the cable. (2) Although the pressing portion 36 of the housing 12 is composed of the pair of left and right individual pressing portions 38 and the pair of left and right individual pressing portions 38 respectively press the pair of left and right protrusions 64 of the retainer 16 in the above embodiment, a pressing portion may simultaneously press the pair of left and right protrusions 64. (3) Although the locking lance 44 is provided with the projections 64 and the pressing portion 36 of the housing 12 presses the projections 64 in the above embodiment, a projection may be provided on a pressing portion without providing any projection on a locking lance, and the projection of the pressing portion may press a curved portion of the locking lance. (4) For example, although deflection is made difficult for the displacement preventing portions 72 by coupling the both ends of the pair of upper and lower displacement preventing portions 72 by the pair of left and right coupling portions 74, respectively, in the above embodiment, the pair of left and right coupling portions 74 may not be provided, and deflection may be made difficult for the displacement preventing portions by being made thicker. (5) Further, a retainer and locking lances may be integrally molded. The integrally molded retainer(s) and locking lances are preferred from the viewpoint of reducing cost as compared with the case where the retainer and the locking lances are molded individually. Further, in the case of integrally molding the retainer and the locking lances, mold removing holes may be necessary. In this case, when the second insertion holes are mold removal holes, it is preferable because intrusion of water also through the water wetting suppression wall can be suppressed while facilitating integral molding.List of Reference Numerals10 Connector 12 Housing 14 Cable (wire) 16 Retainer 24 Opening 36 Pressing portion 40 Base end wall 44 Locking lance 48 First insertion hole 50 Second insertion hole 62 Water wetting suppression wall 70 Second slot (slot) 88 Individual water wetting suppression wall 90 Individual water wetting suppression wall coupling portion
