The potting liquid applied to the inside of the shell 3 flows into the space 3 between the first insulating portion 41 and the second insulating portion 42 S). In this case, the shell 3 is in a state in which the portion to which the potting liquid is applied is raised upward. Therefore, the potting liquid can flow to be filled in the spaced space S between the first insulating portion 41 and the second insulating portion 42 by gravity.

Accordingly, when the first insulating portion 41 is inserted into the shell 3, the blocking member 412 can be pressed against the inner surface 31a of the shell 3 to be compressed. The blocking member 412 presses the inner surface 31a of the shell 3 with a restoring force so that the sealing force between the inner surface 31a of the shell 3 and the outer surface of the first insulating portion 41 Can be increased.

The plug connector can be separated from the contacts 2 by moving toward the front (in the direction of the arrow of the FD) and detaching from the shell 3.

The shell 3 may support the first insulation part 41. The first insulating portion 41 may be inserted into the shell 3 by moving toward the front (in the arrow direction of the FD) while the contacts 2 are engaged. The first insulating portion 41 can be coupled to the shell 3 such that the connecting members 21 of the contacts 2 are located inside the shell 3. [

First, when the shell 3 is manufactured through a bending process in which the shell 3 is bent after cutting the plate material, and a joining process in which both ends of the bended plate material are joined together through a processing operation such as welding, The seam 34 is formed through the process. Since the joint 34 is a gap, it must be filled with additional work such as tapping in order to implement the waterproof function. According to this, there is a problem that the shell 3 causes an increase in manufacturing cost due to an increase in the number of workings and a decrease in productivity due to an increase in manufacturing time. Further, even if the shell 3 fills the seam 34 through an additional operation, there is a risk that water or the like penetrates through the seam 34, so that there is a problem that the waterproof performance is low.

In the receptacle connector 1 according to the present invention, the shell body 30 is integrally formed without the seam, so that the outer surface of the shell 3 is realized without a gap due to the seam 34. Accordingly, the receptacle connector 1 according to the present invention is implemented such that the shell 3 has a waterproof function without any additional operation such as tapping or the like in order to fill the joint 34. Therefore, the receptacle connector 1 according to the present invention can be provided with a waterproof function while reducing the number of workings, so that the manufacturing cost can be reduced, and the productivity can be improved by shortening the manufacturing time.

The processing apparatus 200 may be a punch provided in a press facility. The machining apparatus 200 is formed in a shape corresponding to the shell body 30. The plate 100 may be in a state of being supported by a die of a press facility.

Next, when the machining unit 300 is formed into a shape in which the one end of the machining unit 300 is closed and the other end thereof is opened by the machining apparatus 200, a part of the machining unit 300 is cut. Accordingly, the processed portion 300 can be manufactured as the shell body 30 by molding the open end of the processed portion 300. In this case, a step of cutting a portion of the other side of the processing portion 300 may be performed.

The receiving hole 33 may function as a receiving space for receiving the waterproof portion 7. [ The waterproof portion 7 can be realized by applying the potting liquid to the receiving hole 33 at the rear side of the shell 3 (in the direction of the arrow BD) and then curing. The receiving hole 33 may be formed through a step of processing the plate member 100 by a deep drawing method.

The protrusion member 32 may be formed to protrude from the support member 31 at a position spaced apart from the sealing member 6 in the forward direction (arrow direction of the FD). Accordingly, the receptacle connector 1 according to the present invention can realize a structure for preventing the sealing member 6 from being displaced forward (in the arrow direction of the FD) by using the projection member 32. Therefore, the receptacle connector 1 according to the present invention is realized such that the sealing member 6 coupled to the supporting member 31 is held more firmly with the space between the shell 3 and the electronic apparatus sealed .

The protrusion member 32 may be formed to protrude outward from the support member 31 so as to seal the outer surface of the shell 3 and the frame in contact with the frame of the electronic apparatus.

The size of the protrusion member 32 may be larger than the size of the insertion hole. In this case, the protrusion member 32 is fixed to the frame in an interference fit manner, thereby further increasing the sealing force between the outer surface of the shell 3 and the frame.

The area where the wedge member 512 is formed on the plane formed by the first axial direction (X-axis direction) and the second axial direction (Y-axis direction) is determined such that the through hole 422 and the engagement hole 522 overlap Is formed. The wedge member 512 can pass through the through hole 422 and the coupling hole 522 of the insulating portion 4 coupled to the shell 3.

The second insulation portion 42 may include a plurality of the through holes 422. The through holes 422 may be disposed on both sides of the second insulating member 421 with respect to the first axis direction (X axis direction).

When the lower cover 52 includes a plurality of engagement holes 522 spaced along the third axis direction (Z-axis direction), the through-holes 422 extend in the third axial direction (Z-axis direction) As shown in FIG.

Referring to Fig. 24, the sealing member 6 of the receptacle connector 1 according to the present invention may include a second sealing protrusion 63. Fig.

The second sealing protrusion 63 is provided to prevent rotation of the sealing body 61. The second sealing protrusion 63 protrudes from the sealing body 61 with reference to the second axial direction (Y-axis direction). The second sealing protrusion 63 protrudes from the sealing body 61 toward the rear side (in the direction of the arrow BD).

For example, since the sealing body 61 can be formed in an elliptical annular shape corresponding to the shape of the shell 3, the sealing body 61 can be parallel to the second axial direction (Y-axis direction) It can rotate about one rotation axis. The sealing member 6 is made of a material that can be elastically compressed so that the sealing body 61 is repeatedly contacted with the frame of the electronic device to cause wear. As the rotation is repeated, the amount of wear generation may increase.

Accordingly, the receptacle connector 1 according to the embodiment of the present invention restricts 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 that the service life is prolonged in comparison with 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 supporting groove 53 (shown in FIG. 23). The sealing member 6 may be coupled to the shell 3 and the cover 5 such that the second sealing protrusion 63 is inserted into the supporting groove 53. Accordingly, the support groove 53 can restrict the rotation of the sealing body 61 by supporting the second sealing protrusion 63. [0053]

The second sealing protrusion 63 may be formed to have the same length as the supporting groove 53 with respect to the second axial direction (Y-axis direction). The second sealing protrusion 63 may be formed to have a shorter length than the same length of the support groove 53 with respect to the second axial direction (Y-axis direction).

24, the support groove 53 is formed in the upper cover 51, but the present invention is not limited thereto. Accordingly, the support groove 53 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.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. Will be clear to those who have knowledge of.
