The housing member 12 has a shielding wall 40 projecting toward the first surface 34a in the closed portion 34 of the grommet main body portion 31. The shielding wall 40 projects from the base 23 of the retainer 22.

As shown in FIG. 2, the shielding wall 40 intersects the line segments X1 and X2 connecting the first opening 36 and the first end portion 15a of the terminal 15 when viewed from the direction in which the shielding wall 40 projects. 1 It has a shielding wall 41. Specifically, the first shielding wall 41 is a line connecting one first opening 36 and the first end portion 15a on the side closer to the first first opening 36 when viewed from the direction in which the shielding wall 40 projects. It intersects the minute X1. Further, the first shielding wall 41 intersects the line segment X2 connecting the other first opening 36 and the first end portion 15a on the side closer to the other first opening 36. In other words, the first shielding wall 41 is located between the shortest distance between the first opening 36 and the first end portion 15a when viewed from the direction in which the shielding wall 40 projects. The first shielding wall 41 has a contact portion 42 in contact with the first surface 34a of the closed portion 34 of the grommet main body portion 31.

Further, the shielding wall 40 surrounds the first end portion 15a when viewed from the direction in which the shielding wall 40 protrudes. Further, the shielding wall 40 extends toward the electric wire through hole 38.
Specifically, the shielding wall 40 has the first shielding wall 41, the base wall 43, the second shielding wall 44, and the third shielding wall 45. The base wall 43 is located on the retainer 22 on the side opposite to the side where the wire through hole 38 is located. The first shielding wall 41 extends from one end of the base wall 43 in a direction orthogonal to the base wall 43. The second shielding wall 44 extends from the intermediate portion of the base wall 43 in a direction orthogonal to the base wall 43. The third shielding wall 45 extends from the other end of the base wall 43 in a direction orthogonal to the base wall 43. The first shield wall 41, the second shield wall 44, and the third shield wall 45 extend in parallel, and extend from the base wall 43 toward the electric wire through hole 38. Then, when viewed from the direction in which the shielding wall 40 projects, the first end portion 15a of one terminal 15 is arranged within the range surrounded by the first shielding wall 41, the second shielding wall 44, and the base wall 43. .. Further, the first shielding wall 41, the second shielding wall 44, and the base wall 43 regulate the direction of one electric wire 14 so as not to deviate from the direction toward the one electric wire through hole 38. Further, the first end portion 15a of the other terminal 15 is arranged within the range surrounded by the second shielding wall 44, the third shielding wall 45, and the base wall 43 when viewed from the direction in which the shielding wall 40 protrudes. .. Further, the second shielding wall 44, the third shielding wall 45, and the base wall 43 regulate the direction of the other electric wire 14 so as not to deviate from the direction toward the other electric wire through hole 38.

The base wall 43, the second shield wall 44, and the third shield wall 45 project to the same height as the first shield wall 41. In other words, the base wall 43, the second shield wall 44, and the third shield wall 45 have the same amount of protrusion of the retainer 22 from the base 23 as the first shield wall 41. That is, the entire shielding wall 40 projects to the same height. Then, the base wall 43, the second shielding wall 44, and the third shielding wall 45 come into contact with the first surface 34a of the closing portion 34 in the same manner as the first shielding wall 41.

As shown in FIG. 3, the grommet main body 31 has a through hole 34c penetrating the first surface 34a and the second surface 34b. The retainer 22 has a protrusion 50 that protrudes from the shielding wall 40. The retainer 22 has a plurality of protrusions 50. Each protrusion 50 projects from the first shielding wall 41. The protruding portion 50 has a main body portion 51 connected to the shielding wall 40 and a locking portion 52 protruding in a direction intersecting the protruding direction of the main body portion 51. The locking portion 52 is arranged at the tip of the main body portion 51. Then, the protruding portion 50 penetrates the through hole 34c. The locking portion 52 is in contact with the second surface 34b of the grommet main body portion 31. That is, the locking portion 52 has a third surface 53 facing the second surface 34b of the grommet main body portion 31. The third surface 53 is in contact with the second surface 34b. Further, the locking portion 52 has a tapered portion 54 that tapers toward the protruding direction of the main body portion 51. Specifically, the tip portion of the protruding portion 50 including the locking portion 52 of the present embodiment constitutes a conical portion 55 having a conical shape that tapers in the protruding direction.

As shown in FIG. 4, in a state where the grommet 13 is not attached to the housing member 12, the dimension A1 between the first surface 34a and the second surface 34b of the grommet main body 31 is the contact portion 42 of the shielding wall 40. It is larger than the dimension A2 between the locking portion 52 and the third surface 53 of the locking portion 52. As a result, when the grommet 13 is attached to the housing member 12, the closed portion 34 of the grommet main body 31 is elastically deformed between the contact portion 42 and the third surface 53. As a result, the state in which the first surface 34a of the grommet main body 31 is in contact with the contact portion 42 of the first shielding wall 41 is maintained. That is, if the dimension A1 is smaller than the dimension A2, the first surface 34a may be separated from the contact portion 42 of the first shielding wall 41, but the dimension A1 is larger than the dimension A2. It is prevented that the first surface 34a is separated from the contact portion 42 of the first shielding wall 41. In the present embodiment, the locking portion 52 prevents the first surface 34a of the grommet main body 31 from being separated from the shielding wall 40, but the first surface 34a is prevented even when the locking portion 52 is not present. Is set to come into contact with the shielding wall 40. That is, the dimensions of the housing member 12 and the grommet 13 are set so that the first surface 34a is in contact with the shielding wall 40 even when the locking portion 52 is not present when the housing member 12 and the grommet 13 are assembled.

Next, the operation of the connector 11 configured as described above will be described.
For example, a part of the housing member 12 in the connector 11 may be exposed to the outside when an external connector is connected, and may be exposed to water when it rains or the like. Then, even if the end portion of the housing member 12 on the outer side of the vehicle is flooded and, for example, water is transmitted to the first end portion 15a side of the terminal 15, the grommet main body portion 31 allows water to enter the inside of the vehicle. Is prevented. Further, the water transmitted to the first end portion 15a side of the terminal 15 flows downward by the discharge pipe portion 32 and is quickly discharged to a portion where there is no problem even if it is exposed to external water.

Further, dust outside the connector 11 may enter the inside of the grommet main body 31 via the discharge pipe portion 32, but is suppressed from reaching the terminal 15 by the first shielding wall 41. Further, the dust that has entered the inside of the grommet main body 31 through the discharge pipe 32 may reach the terminal 15 while wrapping around the first shielding wall 41, but the base wall 43, the second shielding wall 44, and the second shield wall 43. 3 It becomes difficult to reach the terminal 15 due to the shielding wall 45.

Next, the effects of the above embodiment will be described below.
(1) The first shielding wall 41 intersects line segments X1 and X2 connecting the first opening 36 of the discharge pipe portion 32 and the first end portion 15a of the terminal 15 when viewed from the direction in which the shielding wall 40 projects. , Has a contact portion 42 in contact with the first surface 34a of the grommet main body portion 31. In other words, the first shielding wall 41 has a contact portion 42 in contact with the first surface 34a of the grommet main body portion 31, from the first opening 36 of the discharge pipe portion 32 to the first end portion 15a of the terminal 15. Located between the shortest paths to go. Therefore, the dust that has entered the inside of the grommet main body 31 through the discharge pipe 32 is less likely to reach the terminal 15 than in the case where the first shielding wall 41 is not provided, and the dust adheres to the terminal 15. Is suppressed.

(2) Since the shielding wall 40 surrounds the first end portion 15a of the terminal 15 when viewed from the direction in which the shielding wall 40 protrudes, it becomes difficult for dust to reach the terminal 15, and dust adheres to the terminal 15. It is more suppressed.

(3) Since the shielding wall 40 extends toward the electric wire through hole 38, the direction of the electric wire 14 connected to the terminal 15 can be restricted so as not to deviate from the direction toward the electric wire through hole 38. Further, since the shielding wall 40 extends toward the electric wire through hole 38, it is not necessary to bend the electric wire 14 significantly between the terminal 15 and the electric wire through hole 38 for arrangement.

(4) The protruding portion 50 protruding from the shielding wall 40 penetrates the through hole 34c, and the locking portion 52 of the protruding portion 50 is in contact with the second surface 34b of the grommet main body 31, so that the grommet main body 31 is the first. It is possible to prevent the one surface 34a from separating from the shielding wall 40. Therefore, it is suppressed that the dust passes between the first surface 34a of the grommet main body 31 and the shielding wall 40 toward the terminal 15, and the adhesion of the dust to the terminal 15 is suppressed.

(5) Since the locking portion 52 is arranged at the tip of the main body 51, the amount of protrusion of the protruding portion 50 is suppressed as compared with the case where the locking portion 52 is arranged at the intermediate portion of the main body 51. And the connector 11 can be miniaturized.

(6) Since the locking portion 52 has tapered details 54 that taper toward the protruding direction of the main body 51, it becomes easy to insert the protruding portion 50 into the through hole 34c of the grommet main body 31, and the connector 11 Assembling workability is improved.

(7) The dimension A1 between the first surface 34a and the second surface 34b of the grommet main body 31 is larger than the dimension A2 between the contact portion 42 of the shielding wall 40 and the third surface 53 of the locking portion 52. big. Therefore, the closed portion 34 of the grommet main body portion 31 is sandwiched between the contact portion 42 and the third surface 53 in a state of being elastically deformed. Therefore, it becomes possible to more reliably maintain the state in which the first surface 34a of the grommet main body 31 is in contact with the contact portion 42 of the shielding wall 40.

(8) Since the protruding portion 50 protrudes from the first shielding wall 41, it is possible to further prevent the first surface 34a of the grommet main body portion 31 from separating from the contact portion 42 of the first shielding wall 41.
(9) Since the housing member 12 has a plurality of projecting portions 50 and the plurality of projecting portions 50 project from the first shielding wall 41, the first surface 34a of the grommet main body portion 31 is the first shielding wall 41. It is possible to suppress the separation from the contact portion 42 more stably.

This embodiment can be modified and implemented as follows. The present embodiment and the following modified examples can be implemented in combination with each other within a technically consistent range.
-In the above embodiment, the protruding portion 50 is said to protrude from the first shielding wall 41, but the present invention is not limited to this, and the protruding portion 50 may protrude from another portion of the shielding wall 40.

For example, as shown in FIGS. 5 and 6, in addition to the projecting portion 50 of the above embodiment, the projecting portion 60 may be configured to project from the third shielding wall 45 as well. By doing so, it is possible to prevent the first surface 34a of the grommet main body 31 from separating from the third shielding wall 45. Further, of course, the protruding portion may be configured to protrude from the second shielding wall 44, or the protruding portion may be configured to protrude from the base wall 43. Further, the number of the protrusions 50 and 60 may be changed to another number.

-In the above embodiment, the shielding wall 40 surrounds the first end portion 15a of the terminal 15 when viewed from the direction in which the shielding wall 40 protrudes, but the present invention is not limited to this, and at least the first shielding wall 41 is provided. If it has, it may be configured not to surround the first end portion 15a. Further, in the above embodiment, the first end portion 15a is arranged inside the shielding wall 40 having an opening on one side when viewed from the direction in which the shielding wall 40 protrudes, but all directions are closed. The first end portion 15a may be arranged inside the shielding wall having the shape of the above. In this case, the electric wire 14 is drawn out in the direction in which the shielding wall 40 protrudes, for example.

-In the above embodiment, the shielding wall 40 is said to extend toward the electric wire through hole 38, but the present invention is not limited to this, and the shielding wall 40 may be configured not to extend toward the electric wire through hole 38. That is, the shielding wall 40 may not have a function of restricting the direction of the electric wire 14 so as not to deviate from the direction toward the electric wire through hole 38.

-In the above embodiment, the housing member 12 has a protrusion 50, but the present invention is not limited to this, and the housing member 12 may be configured not to have the protrusion 50. For example, the first surface 34a of the grommet main body 31 may be prevented from being separated from the shielding wall 40 by another structure, an adhesive, or the like. Specifically, for example, although the housing member 12 does not have the protruding portion 50, the housing member 12 and the grommet 13 are in contact with the shielding wall 40 when the first surface 34a is assembled. Each dimension may be set as described above.

In the above embodiment, the locking portion 52 is arranged at the tip of the main body 51, but the present invention is not limited to this, and the locking portion 52 may be arranged at the intermediate portion of the main body 51.
In the above embodiment, the locking portion 52 has a tapered portion 54 that tapers toward the protruding direction of the main body portion 51, but the present invention is not limited to this, and the locking portion 52 may have a configuration that does not have the tapered detail 54. .. Further, in the above embodiment, the tip portion of the projecting portion 50 including the locking portion 52 constitutes a conical portion 55 having a conical shape that tapers in the projecting direction, but the present invention is not limited to this.
