[0009] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to this embodiment. In addition, the components in the following embodiments include those that are replaceable and easy for a person skilled in the art, or those that are substantially the same.

[0010] [Embodiment] This embodiment relates to a connector. In the following description, among a first direction, a second direction, and a third direction that intersect with each other, the first direction is referred to as the "drawing direction X", the second direction is referred to as the "width direction Y", and the third direction is referred to as the "mounting direction Z". Here, the drawing direction X, the width direction Y, and the mounting direction Z are mutually perpendicular. Note that the perpendicular direction referred to here includes substantially perpendicular directions. The drawing direction X corresponds to the drawing direction of the electric wires drawn out from the connector. The mounting direction Z corresponds to the direction in which the cover is attached to the housing. In addition, each direction used in the following description represents a direction in which each part is assembled with respect to each other, unless otherwise specified.

[0011] 1 and 2, connector 1 is a connector used for connection to an object to be connected (not shown), and includes a housing 2, a cover 3, and a waterproofing member 4. Connector 1 is mounted, for example, on a vehicle, and configured to house components such as terminals and pull out electric wires from the inside to the outside. The object to be connected is, for example, a vehicle unit mounted on or provided in the vehicle.

[0012] The housing 2 is a component that holds components such as terminals, and is formed, for example, by resin molding. The housing 2 has a box-shaped main body 21. The main body 21 is a hollow box body, and one wall surface is opened to form an opening 211. The housing 2 is provided with a flange 23. The flange 23 is a plate-shaped portion that extends from the main body 21 in a direction intersecting the mounting direction Z, and forms a mounting hole 231 through which a fastening member such as a bolt is inserted. The mounting hole 231 is formed toward the mounting direction Z, and is formed so as to penetrate the flange 23. A plurality of flanges 23 are provided, for example three flanges, and are provided spaced apart from each other in the drawing direction X and the width direction Y.

[0013] The housing 2 is formed with an electric wire pull-out portion 22. The electric wire pull-out portion 22 is a portion for pulling out an electric wire (not shown) from inside the housing 2 to the outside. The electric wire pull-out portion 22 protrudes from the main body portion 21 in a direction intersecting with the mounting direction Z, and is formed, for example, along the pull-out direction X. The electric wire pull-out portion 22 has a cylindrical shape and is formed so that an electric wire can be inserted therein. For example, two sets of electric wire pull-out portions 22 are provided, with two electric wire pull-out portions 22 as one set. In other words, two electric wire pull-out portions 22 are formed side by side in the width direction Y, and the two sets are provided at positions sandwiching the main body portion 21.

[0014] The housing 2 is formed with a locked portion 25. The locked portion 25 is a portion that engages with the locking portion 32 of the cover 3, and is, for example, a protrusion that protrudes from the side surface 21A. The locked portion 25 is formed at a position where the locking portion 32 is to be disposed when the cover 3 is attached to the housing 2. A plurality of locked portions 25 are provided according to the number of locking portions 32 to be installed. The housing 2 is formed with a mating portion 20. The mating portion 20 is a portion that is mated with an object to be connected. The mating portion 20 protrudes in the mounting direction Z from a surface of the main body 21 that faces the object to be connected.

[0015] The cover 3 is a lid member that covers the opening 211 of the housing 2, and is made of, for example, resin. The cover 3 is formed, for example, larger than the housing 2, and is attached so as to cover the opening 211 of the housing 2.

[0016] The cover 3 is formed with a locking portion 32. The locking portion 32 is a portion that engages the cover 3 with the housing 2, and engages with the locked portion 25 of the housing 2. The locking portion 32 extends from an edge portion of the main body 31 of the cover 3 toward the housing 2 along the mounting direction Z. The main body 31 is a plate-like portion that covers the opening 24. A plurality of locking portions 32 are formed at predetermined intervals along the extending direction of the edge portion of the main body 31, and are formed, for example, in a plate shape. The locking portion 32 is disposed along the side surface 21A of the main body portion 21 of the housing 2 in a state in which the cover 3 is attached to the housing 2. The locking portion 32 is provided so as to be elastically deformed and swingable so as to move away from and approach the side surface 21A around the base end portion on the main body 31 side.

[0017] 3, the locking portion 32 is formed with a locking hole 321 and an insertion hole 322. The locking hole 321 is a hole formed so as to penetrate the locking portion 32 from the front to the back. The locking hole 321 is formed with a size that allows the locked portion 25 to be inserted therein. The insertion hole 322 is a hole formed so as to penetrate the locking portion 32 from the front to the back, and is formed, for example, on the base end side of the locking portion 32. The insertion hole 322 is formed with a size that allows the protrusion 41 of the water-stopping member 4 to be inserted therein.

[0018] 2, the water-stopping member 4 is formed of an annular elastic member. The water-stopping member 4 is a packing member that stops water between the housing 2 and the cover 3, and is provided, for example, along the outer edge of the opening 211 of the housing 2 and has a shape that corresponds to the shape of the housing 2.

[0019] The water-stopping member 4 is formed with a protruding portion 41. The protruding portion 41 protrudes toward the outside of the annular water-stopping member 4 in a direction intersecting with the mounting direction Z. A plurality of protruding portions 41 are formed at predetermined intervals along the extending direction A of the water-stopping member 4. The protruding portion 41 is formed with a protruding length capable of protruding outward from the housing 2, and is formed, for example, so as to penetrate the locking portion 32 of the cover 3. The protruding portion 41 has a drainage function and a positioning function. That is, the protruding portion 41 is provided so as to protrude outward from the housing 2 and penetrate the locking portion 32, thereby performing the function of guiding water accumulated around the water-stopping member 4 to the outside of the connector 1 and draining it. In addition, the protruding portion 41 protrudes from the side of the water-stopping member 4, thereby restricting the water-stopping member 4 from moving along the extending direction A, and functions as a portion for positioning the water-stopping member 4 when the water-stopping member 4 is mounted. This is particularly useful when the water-stopping member 4 is not circular in shape.

[0020] As shown in FIG. 4, the water-stopping member 4 is provided, for example, housed in a groove 26 formed in the housing 2. FIG. 4 shows the connector 1 in a state in which the cover 3 is removed from the housing 2. The groove 26 is a groove formed along the outer edge of the housing 2, and is formed by recessing in the mounting direction Z. A notch 262 is formed in a side wall 261 on the outer side of the groove 26. The notch 262 is a hole that cuts out the side wall 261 to connect the groove 26 to the outside of the housing 2. For example, the notch 262 is formed by cutting out the side wall 261 so as to recess it downward from the upper end. The notch 262 is formed to a size that allows the protrusion 41 of the water-stopping member 4 to be inserted therethrough, and is provided according to the formation position of the protrusion 41 of the water-stopping member 4. The notch 262 functions as a drainage path for draining the water W accumulated in the groove 26 to the outside of the housing 2.

[0021] Next, assembly and waterproofing performance of the connector 1 according to this embodiment will be described.

[0022] 2, the connector 1 is assembled by attaching the water-stopping member 4 to the housing 2 and attaching the cover 3 to the housing 2. First, the water-stopping member 4 is attached to the housing 2 by placing the water-stopping member 4 in the groove 26 of the housing 2. The water-stopping member 4 is placed by inserting the water-stopping member 4 into the groove 26 formed on the outer edge of the housing 2. At this time, since the notch 262 formed in the groove 26 is formed according to the position where the protrusion 42 of the water-stopping member 4 is formed, the water-stopping member 4 can be easily placed at a desired position with respect to the groove 26 by inserting the protrusion 41 into the notch 262 and placing the water-stopping member 4 in the groove 26.

[0023] Furthermore, by forming the protrusions 41 on the sides of the water-stopping member 4, the water-stopping member 4 is prevented from moving in the extending direction A within the groove 26 when the cover 3 is attached or the connector 1 is used. This prevents the water-stopping function between the housing 2 and the cover 3 in the connector 1 from being impaired, and the water-stopping function of the connector 1 due to the water-stopping member 4 can be improved.

[0024] Then, once the waterproofing member 4 has been placed on the housing 2, the cover 3 is attached to the housing 2. The cover 3 is attached to the housing 2 so as to cover the opening 211. The cover 3 is moved in the attachment direction Z until the locking portion 32 of the cover 3 engages with the locked portion 25, and fitted to the housing 2. As a result, the locking portion 32 engages with the locked portion 25, the cover 3 is attached to the housing 2, and the assembly of the connector 1 is completed. The connector 1 is then connected to an object to be connected (not shown) for use.

[0025] In FIG. 1, the connector 1 has a water-stopping member 4 disposed between the housing 2 and the cover 3, thereby preventing water from entering the inside of the housing 2. However, water may accumulate around the water-stopping member 4. For example, water may accumulate in the groove 26 that houses the water-stopping member 4. At this time, the water accumulated in the groove 26 is drained to the outside of the connector 1 along the protruding portion 41 of the water-stopping member 4. That is, the water accumulated in the groove 26 is guided to the outside of the connector 1 through the notch 262 of the housing 2 and the insertion hole 322 of the cover 3, and is drained to the outside of the connector 1. Therefore, in the connector 1, water is prevented from accumulating around the water-stopping member 4, and the water-stopping function of the water-stopping member 4 is improved.

[0026] Further, the protrusion 41 is provided penetrating the locking portion 32 in a direction intersecting the mounting direction Z. Therefore, in the connector 1, even when the engagement between the locking portion 32 and the locked portion 25 is released, the protrusion 41 restricts the movement of the cover 3 in the mounting direction Z, and the cover 3 is prevented from coming off the housing 2.

[0027] As described above, the connector 1 according to this embodiment is provided with the protrusion 41 on the water-stopping member 4, which extends outward from the housing 2 and the cover 3. Therefore, the connector 1 according to this embodiment can drain water that accumulates around the water-stopping member 4 to the outside of the connector 1 along the protrusion 41, thereby improving the water-stopping ability of the water-stopping member 4. In the connector 1 of this embodiment, by providing a protrusion 41 on the water-stopping member 4, it is possible to prevent the water-stopping member 4 from moving along the extension direction A, thereby suppressing misalignment and rattling of the water-stopping member 4.

[0028] Furthermore, in the connector 1 according to this embodiment, the protrusion 41 of the waterproofing member 4 is provided to penetrate the locking portion 32 of the cover 3, thereby restricting movement of the cover 3 along the attachment direction Z. Therefore, the connector 1 according to this embodiment can prevent the cover 3 from coming off the housing 2 even when the engagement between the locking portion 32 and the locked portion 25 is released.

[0029] The connector according to the present invention is not limited to the above-described embodiment, and various modifications are possible within the scope of the claims. The connector 1 according to this embodiment may be configured by appropriately combining the components of the embodiments and modified examples described above.

[0030] For example, the connector 1 according to the above embodiment has been described as being mounted on a vehicle, but it may also be used without being mounted on a vehicle. [Explanation of symbols]
