Referring to the drawings, a plug assembly 100 includes a grommet portion 110 and a connector portion 120.

The grommet portion 110 is formed of a silicone material and is coupled to the upper portion of the connector portion 120. Since the grommet part 110 is formed not to cover the entire connector part 120 but to receive only a part of the upper end of the connector part 120, the size of the plug assembly 100 can be minimized, . In addition, since the grommet part 110 is formed in a shape that does not completely cover the connector part 120, the size of the plug assembly 100 can be minimized, the size of the package can be minimized, and the cost can be reduced. Reference numeral 111 in the drawing denotes a body part 111 forming an outer appearance of the grommet part 110 and 112 a connector coupling part 112 connected to the connector part 120.

The connector unit 120 includes a terminal accommodating portion 122 for supplying power for operating various devices mounted on doors of a vehicle and accommodating and connecting a plurality of terminals (not shown) . A sealing member engaging portion 123 is formed at an outer portion of the body portion 121 forming the outer surface of the connector portion 120, to which the sealing member 140 is coupled. For example, the sealing member engaging portion 123 may have a groove shape recessed at a predetermined depth and width from the surface of the connector portion 120. Here, the sealing member 140 may be inserted into the connector portion 120 so as to be firmly coupled to the connector portion 120, and may be double-injected.

According to the present embodiment, since the sealing member 140 and the connector portion 120 are integrally formed by injecting the sealing member 140 with the connector portion 120, the waterproof efficiency of the plug assembly 100 can be improved . Also, it is possible to prevent the sealing member 140 from being peeled off or displaced during the mounting and separating operation of the plug assembly 100, and it is possible to prevent the sealing member 140 from being separated from the connector portion 120.

The sealing member 140 may be formed with a plurality of ribs in the shape of a plurality of protrusions and / or protrusions to increase the waterproof efficiency by increasing the bonding area. However, the present invention is not limited to the drawings, and the shape of the sealing member 140 may be substantially varied.

A lever portion 130 is coupled to one side of the plug assembly 100. For example, the lever portion 130 can use a low insertion force (LIF) lever so that the plug assembly 100 can be easily engaged and detached even with a small force.

The lever portion 130 is hingedly coupled to an engaging pin 125 provided outside the connector portion 120. The lever portion 130 includes an engaging portion 132 coupled to the engaging pin 125 and an extended portion extending from the engaging portion 132 to an upper portion of the grommet portion 110, A handle portion 131 for applying a force to the plug assembly 130 and an action portion 133 formed at an end of the engagement portion 132 for applying a force to the plug assembly 100.

The lever portion 130 may have a "C" shape in cross section so as to be fittable on both side surfaces of the connector portion 120. However, the shape of the lever portion 130 is not limited to the drawings, and may be substantially varied. In order to minimize the size of the plug assembly 100 and to minimize the space required for the operation, the lever portion 130 is formed so that the outermost turning radius of the handle portion 131 is equal to or less than the highest height of the grommet portion 110 . The lever 130 may have a lower center of rotation than the door panel 10 in a state where the connector 120 and the grommet 110 are engaged with each other. The handle portion 131 is partially received in the cap housing 20 while the lever portion 130 is engaged with the upper end portion of the handle portion 131 in a state where the connector portion 120 and the grommet portion 110 are engaged, Is formed higher than the door panel (10).

The acting portion 133 has a saw tooth structure. Here, since the operating portion 133 has a saw tooth structure, the turning radius of the lever portion 130 can be minimized, so that the plug assembly 100 can be minimized.

The door for a vehicle includes a door panel 10 and a cap housing 20 provided inside the door panel 10 to receive and accommodate the plug assembly 100. For reference, the door for a vehicle is not a gist of the present invention, so that only the door panel 10 and the cap housing 20 will be briefly described, and other components will not be described and shown.

The cap housing 20 is provided inside the door panel 10 and accommodates the plug assembly 100. The cap housing 20 may be provided with another terminal (not shown) coupled to the terminals of the connector 120.

A toothed portion 23 is formed in the cap housing 20 so that the operating portion 133 of the lever portion 130 is engaged. For example, the tooth engaging portion 23 may be formed by forming a predetermined number of teeth or gears on the inner wall surface of the plug accommodating portion 21, which is an inner space of the cap housing 20. However, the present invention is not limited to the drawings, and the shape of the toothed portion 23 can be changed into substantially various shapes that can be engaged with the action portion 133. [

One fixing portion (not shown) and two elastic coupling pieces 24 are provided so that the cap housing 20 can be coupled to the door panel 10. For example, the coupling piece 24 is formed of an elastic body such as a leaf spring or the like, and is provided at an upper end of the cap housing 20 to fix the upper end of the cap housing 20 to the door panel 10. In addition, by providing the engaging pieces 24, the cap housing 20 can be easily engaged and separated, and the engaging force can be increased. The cap housing 20 can be fitted to the door panel 10. When the cap housing 20 is fitted into the door panel 10, the fixing part is first fixed to the door panel 10 so that the coupling piece 24 is elastically coupled to the door panel 10, .

7, a housing sealing member 25 for sealing a portion where the cap housing 20 and the door panel 10 are coupled is provided between the cap housing 20 and the door panel 10, .

The chamfered portion 124 is formed at a predetermined angle in a portion of the connector 120 that is in contact with the cap housing 20 when the plug assembly 100 is mounted on the cap housing 20. Since the chamfered portion 124 is formed under the connector 120, the plug assembly 100 can be tilted at a predetermined angle when the plug assembly 100 is mounted on and detached from the cap housing 20, The work is easier and the space required for mounting and dismounting work can be reduced. In addition, by forming the chamfered portion 124 of the connector portion 120, interference between the plug assembly 100 and the door panel 10 can be prevented. In detail, since the space between the door panel 10 and the automobile body is very narrow, it is necessary to perform the operation of separating and connecting the connector portion 120 in such a narrow space during the service of the vehicle, So that it is highly restricted in the performance of the work. However, according to the embodiment of the present invention, since the connector portion 120 can be tilted and coupled to the plug assembly 100, the height of the space required for the connector portion 120 can be reduced. For example, the connector portion 120 may be formed such that the end of the cap housing 20 and the sealing member 140 are in contact with each other when the plug assembly 100 is turned at the maximum angle. According to this embodiment, as described above, the end portion of the cap housing 20 contacts the sealing member 140, so that the sealing member 140 is compressively deformed. As a result, The portion 120 is rotatable and engageable with the plug assembly 100 with more free space.

In order to reduce the height protruding from the door panel 10 when the plug assembly 100 is coupled to the door, a part of the lever portion 130 may be formed to be received in the cap housing 20. 6, when the lever portion 130 is rotated to engage the plug assembly 100 with the cap housing 20, a portion of the handle portion 131 can be received in the cap housing 20 have. A lever accommodating portion 22 may be formed in the cap housing 20 to receive a portion of the handle portion 131. The inner space of the cap housing 20 may be divided into a plug accommodating portion 21 and a lever accommodating portion 22 in which the plug assembly 100 is accommodated.

Here, when the handle portion 131 is received in the cap housing 20, a part of the handle portion 131 for locking and unlocking the plug assembly 100 is received so as to be exposed to the upper portion of the door panel 10 .

However, the present invention is not limited thereto, and it is also possible that the handle portion 131 is not accommodated in the cap housing 20 but located on the door panel 10. This is because the height of the handle portion 131 is lower than the height of the grommet portion 110 when the plug assembly 100 is coupled to the handle portion 131, Since there is no influence on minimizing the coupling height between the plug assembly 100 and the grommet portion 110,

4 to 6 are views for explaining the operation of mounting the plug assembly 100 on the door. Referring to FIG. 4, the plug assembly 100, in which the connector 120 and the grommet 110 are coupled, When the lever portion 130 is operated after being inserted into the housing 20, the plug assembly 100 is inserted into and fixed to the cap housing 20. The lever portion 130 is engaged with the toothed portion 23 formed in the cap housing 20 so that the teeth formed on the operating portion 133 are engaged with the handle portion 131 of the lever portion 130, The plug assembly 100 is inserted into and coupled with the cap housing 20 as the operating portion 133 and the toothed portion 23 are rotated while being engaged with each other. Also, since the lever 130 is a lever of the LIF type, the plug assembly 100 can be easily coupled to the cap housing 20 without applying a large force.

Conversely, when the plug assembly 100 is separated from the cap housing 20, as opposed to the above-described operation, when the user lifts the handle portion 131, the action portion 133 and the toothed portion 23 are engaged with each other The plug assembly 100 can be separated from the cap housing 20 by a small force.

According to the present embodiments, since the connector 120 and the grommet 110 are modularized and joined to the cap housing 20, the time for mounting and dismounting the plug assembly 100 can be shortened. Since the sealing member 140 is formed integrally with the connector 120, the waterproof efficiency can be improved and the sealing member 140 can be prevented from being separated from the connector 120. Further, since the LIF type lever 130 is provided, it is easy to mount and separate the plug assembly 100 even with a small force. Since the height of the grommet part 110 protruding from the door panel 10 can be minimized and the turning radius of the lever part 130 is lower than the grommet part 110, The size and the package of the plug assembly 100 can be minimized, and the space required for the operation can be reduced. In addition, the height of the lever portion 130 and the grommet portion 110 is minimized to facilitate A / S and maintenance work.
