[Explanation of Embodiments of the present disclosure]
First, embodiments of the present disclosure will be listed and described.

The connectors of the present disclosure are
(1) A plurality of terminals electrically connected to a device housed in a case mounted on a vehicle, an electric wire electrically connected to the terminals, a connector housing holding the terminals, and the connector housing. The shield shell includes a housing portion provided with a storage space for housing the connector housing, and a fixing hole through which a fixing member for fixing the shield shell is inserted into the case. The housing portion is a connector having a fixing portion provided, and the housing portion has an inclined surface inclined with respect to a reference plane perpendicular to the first direction which is a penetrating direction of the fixing hole on the inner wall surface of the housing portion. ..

According to the above aspect, the liquid such as water adhering to the inclined surface is suppressed from staying at the place where the liquid adheres on the inclined surface. Therefore, it is possible to prevent the liquid adhering to the inner wall surface of the shield shell from staying at the adhering place.

(2) The accommodating portion has an outlet for communicating the accommodating space with the outside of the shield shell, and the connector is arranged on the inclined surface so that the reference surface and the horizontal plane are parallel to each other. If so, it is preferable to incline the adhering liquid so as to guide it toward the discharge port.

According to the above aspect, the liquid such as water adhering to the inclined surface is guided toward the discharge port by the inclined surface. Therefore, the liquid can be easily discharged from the discharge port to the outside of the shield shell. As a result, it is possible to prevent water from accumulating inside the shield shell.

(3) It is preferable that the accommodating portion has a notch portion that expands the discharge port.

According to the above aspect, since the discharge port is enlarged by the notch portion, the liquid guided toward the discharge port by the inclined surface can be easily discharged from the discharge port to the outside of the shield shell. As a result, it is possible to further suppress the accumulation of water inside the shield shell.

(4) The accommodating portion exposes an arranging portion having the inclined surface, a separate portion attached to the arranging portion to form the accommodating space together with the arranging portion, and a plurality of the terminals to the outside of the shield shell. The exposed port is the discharge port, and a part of the inner peripheral surface forming an annular shape of the exposed port is formed by the separate portion, and the notch portion is formed by the separate portion. It is preferable that it is provided in the separate portion.

According to the above aspect, since the discharge port also serves as an exposure port for exposing the terminals to the outside of the shield shell, the structure of the shield shell is complicated as compared with the case where the discharge port and the exposure port are provided respectively. Can be suppressed.

(5) The connector housing holds an electrical connection portion between the terminal and the electric wire inside the connector housing, and in the accommodating portion, the electric wire drawn from the connector housing is the first. It has a wire insertion hole that is inserted along a second direction that intersects the direction, the wire is drawn out of the accommodation space from the wire insertion hole, and the discharge port is in the second direction. Of both ends of the accommodating portion, the distance between the reference surface and the inclined surface is the distance in the first direction, which is provided at a position close to the end opposite to the end close to the electric wire insertion hole. It is preferable that the number increases monotonically as the distance from the wire insertion hole is increased along the second direction.

According to the above aspect, when the connector is arranged so that the inclined surface is arranged below the reference surface in the vertical direction, the liquid adhering to the inclined surface flows toward the electric wire drawn from the connector housing. It becomes possible to discharge from the discharge port while suppressing this.

(6) The connector housing holds an electrical connection portion between the terminal and the electric wire inside the connector housing, and in the accommodation space, the outer wall surface of the connector housing and the inner wall surface of the shield shell The accommodating portion has a sealing member for sealing between the two, and the accommodating portion includes an electric wire insertion hole through which the electric wire drawn from the connector housing is inserted along a second direction intersecting the first direction, and the accommodating space. It has a drain hole for communicating with the outside of the shield shell, the electric wire is drawn out from the electric wire insertion hole to the outside of the accommodation space, and the drain hole is in the first direction. It is preferable that the seal member is located on the inclined surface side and is located on the side opposite to the electric wire insertion hole on both sides of the seal member in the second direction in the second direction.

According to the above aspect, the liquid that has entered the inside of the shield shell can be discharged to the outside of the shield shell not only from the discharge port but also from the drain hole. The drain hole is located on the inclined surface side of the seal member in the first direction, and is located on both sides of the seal member in the second direction opposite to the electric wire insertion hole in the second direction. Therefore, when the connector is arranged so that the drain hole is below the seal member in the vertical direction, the liquid that has entered the inside of the shield shell reaches the shield shell so that the water level of the liquid reaches the seal member. It is possible to suppress the accumulation inside the.

(7) It is preferable that the drain hole is provided at a position closer to the electric wire insertion hole in the second direction than the center of the second direction on the inclined surface.

According to the above aspect, the liquid that could not be guided to the discharge port due to the inclined surface can be discharged to the outside of the shield shell from the drain hole near the electric wire insertion hole.

(8) The penetration direction of the drain hole is preferably a direction that intersects with the first direction.

According to the above aspect, when the connector is arranged so that the first direction is along the vertical direction, it is possible to prevent the drain hole from opening downward. Therefore, it is possible to prevent foreign matter such as stepping stones from entering the inside of the shield shell through the drain hole when the vehicle is running.

According to the above aspect, when the connector is arranged so that the inclined surface 165 is arranged below the fixed surface 152 in the vertical direction, the liquid adhering to the inclined surface 165 is drawn from the connector housing 35. It becomes possible to discharge from the first opening 113 while suppressing the flow toward 33 and 34.

(6) The connector housing 35 holds an electrical connection portion between the terminals 31 and 32 and the electric wires 33 and 34 inside the connector housing 35. The accommodation space 120 includes wire-side sealing members 48 and 49 that seal between the outer wall surface of the connector housing 35 and the inner wall surface of the shield shell 36. The accommodating portion 121 communicates the electric wire insertion holes 135 and 136 through which the electric wires 33 and 34 drawn from the connector housing 35 are inserted along the X direction intersecting the Z direction with the accommodating space 120 and the outside of the shield shell 36. It has a drain hole 164 to be drained. The electric wires 33 and 34 are led out from the electric wire insertion holes 135 and 136 to the outside of the accommodation space 120. The drain hole 164 is located on the inclined surface 165 side of the electric wire side sealing members 48 and 49 in the Z direction, and is an electric wire insertion hole on both sides of the electric wire side sealing members 48 and 49 in the X direction in the X direction. It is preferably located on the opposite side of 135 and 136.

According to the above aspect, the liquid that has entered the inside of the shield shell 36 can be discharged to the outside of the shield shell 36 not only from the first opening 113 but also from the drain hole 164. The drain hole 164 is located on the inclined surface 165 side of the electric wire side sealing members 48 and 49 in the Z direction, and the electric wire on both sides of the electric wire side sealing members 48 and 49 in the X direction in the X direction. It is located on the opposite side of the insertion holes 135 and 136. Therefore, when the connector 30 is arranged so that the drain hole 164 is below the electric wire side sealing members 48 and 49 in the vertical direction, the liquid that has penetrated into the shield shell 36 has a water level of the liquid. Accumulation inside the shield shell 36 can be suppressed so as to reach the electric wire side sealing members 48 and 49. Therefore, it is possible to further prevent the liquid that has entered the inside of the shield shell 36 from adhering to the electric wires 33 and 34.

Further, since the vehicle equipped with the connector 30 travels in various environments, the liquid that penetrates into the shield shell 36 may contain salt. Since the accommodating portion 121 has the drain hole 164, it is possible to prevent the liquid from adhering to the electric wire side sealing members 48 and 49. Therefore, it is suppressed that the salt contained in the liquid accelerates the aged deterioration of the electric wire side sealing members 48 and 49. As a result, it is possible to suppress a decrease in the sealing property of the electric wire side sealing members 48 and 49 due to contact with the liquid containing salt.

(7) The drain hole 164 is provided at a position on the inclined surface 165 closer to the electric wire insertion holes 135 and 136 in the X direction than the center in the X direction.

(8) The penetration direction of the drain hole 164 is the X direction that intersects the Z direction.

According to the above aspect, when the connector 30 is arranged so that the Z direction is along the vertical direction, it is possible to prevent the drain hole 164 from opening downward. Therefore, it is possible to prevent foreign matter such as stepping stones from entering the inside of the shield shell 36 through the drain hole 164 when the vehicle is running.

(9) The second opening 114 covered by the separate body portion 92 is in the penetrating direction of the electric wire insertion holes 135 and 136, and is open in the X direction in which the terminals 31 and 32 are lined up. Further, the separate body portion 92 forms the inner peripheral surface of the first opening 113 at the end in the X direction opposite to the electric wire insertion holes 135 and 136 in the first opening 113. Therefore, the connector housing 35 holding the terminals 31 and 32 can be easily inserted into the accommodating portion 121 from the second opening 114.
