The sealing member 6 may be installed in the shell 3 so as to surround the outer surface of the shell 3 .

To this end, the shell 3 may include a support member 31 (shown in FIG. 10 ). The support member 31 is for supporting the sealing member 6 . The shell 3 protrudes from the cover 5 toward the front (in the direction of the FD arrow, as shown in FIG. 10 ) so that the support member 31 is positioned outside the cover 5 . 5) can be combined. Accordingly, the support member 31 can support the sealing member 6 so that the sealing member 6 seals between the shell 3 and the electronic device from the outside of the cover 5 . have.

The sealing member 6 may be installed in the shell 3 so as to be positioned on the support member 31 . In this case, an installation groove 50 (shown in FIG. 10 ) is positioned at a portion of the shell 3 protruding from the cover 5 . The sealing member 6 may be installed in the sealing member 6 so as to be located in the installation groove 50 . Based on the second axial direction (Y-axis direction), the sealing member 6 may be implemented to have a shorter length than the length of the installation groove 50 . The sealing member 6 may be installed in the shell 3 so that a portion of the installation groove 50 remains at the front (in the direction of the FD arrow) and the rear (in the direction of the BD arrow), respectively.

Although not shown, based on the second axial direction (Y-axis direction), the sealing member 6 may be implemented to have the same length as the length of the installation groove 50 . That is, based on the second axial direction (Y-axis direction), the length of the sealing member 6 and the length of the installation groove 50 may be implemented to be the same. In this case, the sealing member 6 may be installed in the shell 3 so as to cover the entire surface of the support member 31 protruding from the cover 5 in the shell 3 . Accordingly, the receptacle connector 1 according to the present invention can further improve the waterproof performance of the electronic device.

The shell 3 may include a protrusion member 32 (shown in FIG. 10 ).

The protrusion member 32 may be formed to protrude outwardly from the support member 31 . The protrusion member 32 may be formed to protrude from the support member 31 at a position spaced apart from the sealing member 6 toward the front (in the direction of the FD arrow). Accordingly, the receptacle connector 1 according to the present invention can implement a structure that prevents the sealing member 6 from being separated toward the front (FD arrow direction) by using the protrusion member 32 . Therefore, the receptacle connector 1 according to the present invention is implemented so that the sealing member 6 coupled to the support member 31 is more firmly maintained in a sealed state between the shell 3 and the electronic device. can

The protrusion member 32 may be formed to protrude outwardly from the support member 31 so as to be in contact with the frame of the electronic device to seal the outer surface of the shell 3 and the frame. When an insertion hole into which the protrusion member 32 is inserted is formed in the frame, the size of the protrusion member 32 may be the same as the size of the insertion hole. Accordingly, the protrusion member 32 is inserted into the insertion hole to be in close contact with the frame, thereby sealing between the outer surface of the shell 3 and the frame. The size of the protrusion member 32 may be implemented to be larger than the size of the insertion hole. In this case, the protrusion member 32 is fixed to the frame by an interference fit method, thereby further increasing the sealing force between the outer surface of the shell 3 and the frame.

The protrusion member 32 may be formed to protrude outward from the outer surface of the support member 31 along the circumferential direction of the support member 31 . The protrusion member 32 may be formed in an elliptical ring shape as a whole, but is not limited thereto, and may be formed in a different shape as long as it can prevent the sealing member 6 from being separated toward the front (FD arrow direction). could be The protrusion member 32 may be formed to protrude outwardly from the end of the support member 31 toward the front (in the direction of the FD arrow).

The sealing member 6 may include a sealing body 61 (shown in FIG. 10) and a first sealing protrusion 62 (shown in FIG. 10).

The sealing body 61 is in contact with the shell 3 . The sealing member 6 may be installed in the shell 3 by being disposed so that the sealing body 61 surrounds the outer surface of the shell 3 . The sealing body 61 may be formed to have a rectangular cross section. In this case, the sealing body 61 may be formed in the form of an elliptical ring as a whole while having a rectangular cross section. Although not shown, the sealing body 61 may be formed to have a cross section of a shape other than a rectangular cross section as long as it has a shape capable of implementing a waterproof function. In addition, as long as the sealing body 61 can implement a waterproof function, it may be formed in a shape other than the overall oval ring shape.

The first sealing protrusion 62 is in contact with the frame of the electronic device. The first sealing protrusion 62 is formed to protrude from the sealing body 61 . The first sealing protrusion 62 may be formed on the sealing body 61 so as to protrude outwardly from the shell 3 toward the sealing body 61 . For example, the first sealing protrusion 62 may be formed to protrude from the sealing body 61 in the outward direction to a length of 0.5 mm. Based on the second axial direction (Y-axis direction), the first sealing protrusion 62 may be formed to have a shorter length than that of the sealing body 61 .

When the sealing member 6 is installed in the shell 3, the first sealing protrusion 62 may be formed to have a size that protrudes more than the outer surface of the cover 5. Accordingly, the first sealing protrusion 62 is elastically compressed as it is in close contact with the frame of the electronic device, thereby pressing the frame of the electronic device by the restoring force. Therefore, the receptacle connector 1 according to the present invention can be implemented to have better waterproof performance.

The first sealing protrusion 62 may be formed in a shape that decreases in size as it protrudes from the sealing body 61 . For example, the first sealing protrusion 62 may be formed to have a trapezoidal cross section. In this case, the first sealing protrusion 62 may have a trapezoidal cross section and be formed in an elliptical ring shape as a whole. Although not shown, the first sealing protrusion 62 may be formed to have a cross-section of a shape other than a trapezoidal cross-section as long as it can implement a waterproof function. In addition, as long as the first sealing protrusion 62 can implement a waterproof function, it may be formed in a shape other than an elliptical ring shape as a whole.

The second sealing protrusion 63 is for preventing rotation of the sealing body 61 . The second sealing protrusion 63 is formed to protrude from the sealing body 61 with respect to the second axial direction (Y-axis direction). The second sealing protrusion 63 is formed to protrude from the sealing body 61 toward the rear (BD arrow direction).

For example, since the sealing body 61 may be formed in an elliptical ring shape to correspond to the shape of the shell 3 , it is parallel to the second axial direction (Y-axis direction) in the state installed in the shell 3 . It can rotate about one axis of rotation. And, as the sealing member 6 is formed of a material that can be elastically compressed, abrasion occurs while the sealing body 61 repeatedly contacts the frame of the electronic device. As the rotation is repeated, the amount of wear may increase.

Accordingly, the receptacle connector 1 according to the present invention limits the rotation of the sealing body 61 by the second sealing protrusion 63 , thereby reducing the amount of wear of the sealing body 61 . Therefore, the receptacle connector 1 according to the present invention has an advantage in that the service life is extended as compared to the comparative example in which the second sealing protrusion 63 is not included.

When the sealing member 6 includes the second sealing protrusion 63 , the cover 5 may include a support groove 51a (shown in FIG. 2 ). The sealing member 6 may be coupled to the shell 3 and the cover 5 so that the second sealing protrusion 63 is inserted into the support groove 51a. Accordingly, the support groove 51a supports the second sealing protrusion 63 , thereby limiting the rotation of the sealing body 61 .

Based on the second axial direction (Y-axis direction), the second sealing protrusion 63 may be implemented to have the same length as the support groove 51a. Based on the second axial direction (Y-axis direction), the second sealing protrusion 63 may be implemented to have a shorter length than the same length of the support groove 51a.

2 shows that the support groove 51a is formed in the upper cover 51, but the present invention is not limited thereto. Accordingly, the support groove 51a may be formed in the lower cover 52 or may be formed in a boundary region between the upper cover 51 and the lower cover 52 .
