Accordingly, the receptacle connector 1 according to the present invention increases the blocking force for shielding the radiation of the signal through the rear surface 4b of the insulating portion 4 by using the second blocking member 53b, It is possible to further reduce the occurrence of radiation to the signal through the rear surface 4b side of the insulating portion 4. [ For example, the second blocking member 53b may be formed of a metal.

The second blocking member 53b may be mounted on the substrate to be grounded through the substrate. In this case, the upper cover 51 may be formed of a conductive material and mounted on the substrate so as to be grounded. For example, the upper cover 51 may be formed of metal. The second blocking member 53b may be connected to the upper cover 51 to be electrically connected to the upper cover 51 so that the second blocking member 53b may be grounded through the upper cover 51. [

8, the second blocking member 53b may be formed to have a length that can be mounted on the substrate while being coupled to the upper cover 51, and the second blocking member 53b may be formed to have a length, The rear face 4b of the insulating portion 4 not covered by the receptacle connector 1 can be covered by the substrate as the receptacle connector 1 is mounted on the substrate. Thus, although only the second blocking member 53b is coupled to the upper cover 51 to cover the rear surface 4b of the insulating member 4, the present invention is not limited thereto . For example, the receptacle connector 1 according to the present invention may include a blocking portion for covering the entire rear surface 4b of the insulation portion 4, reflecting the height of the receptacle connector 1 mounted on the substrate. For example, 52 may also include a blocking portion for covering the rear surface 4b of the insulating portion 4. [

The receptacle connector 1 according to the present invention can reduce the occurrence of radiation to the signal by configuring the second blocking member 53b in a configuration different from that of the upper cover 51. [ According to a comparative example in which the second shielding member 53b and the upper cover 51 are integrally formed, the second shielding member 53b is bent with respect to the upper cover 51, 4 because the curved region is formed between the second blocking member 53b and the upper cover 51 due to bending, it is possible to prevent the radiation to the signal May occur.

Therefore, the receptacle connector 1 according to the present invention includes the second blocking member 53b in a configuration different from the upper cover 51, and the second blocking member 53b is fixed to the upper cover 51, Lt; RTI ID = 0.0 > radiation. ≪ / RTI >

The receptacle connector 1 according to the present invention includes a closure member 54 (shown in Fig. 5), thereby further reducing the occurrence of radiation to the signal.

The closure member 54 closes a gap between the upper cover 51 and the second blocking member 53b. The clearance between the upper cover 51 and the second blocking member 53b may be formed in a remaining portion except for the portion where the second blocking member 53b is coupled to the upper cover 51. [ For example, a gap may be formed in a remaining portion except a portion where the second blocking member 53b and the upper cover 51 are connected. The closure member 54 closes a gap between the upper cover 51 and the second blocking member 53b so that the signal is transmitted through the gap between the upper cover 51 and the second blocking member 53b It is possible to prevent the radiation from being generated. Therefore, the receptacle connector 1 according to the present invention blocks the emission of the signal through the rear face 4b side of the insulating portion 4 by using the second blocking member 53b and the closing member 54 By further increasing the blocking force, it is possible to further reduce the occurrence of radiation to the signal through the rear face 4b side of the insulation part 4. [

The closing member 54 is engaged with the upper cover 51 and the second blocking member 53b to thereby cover the gap between the upper cover 51 and the second blocking member 53b . The closing member 54 may be realized by performing laser welding on a gap between the upper cover 51 and the second blocking member 53b.

The cover (5) may include a plurality of the closing members (54). The closing members 54 may be coupled to the upper cover 51 and the second blocking member 53b at positions spaced apart from each other. Accordingly, the receptacle connector 1 according to the present invention partially blocks the gap between the upper cover 51 and the second blocking member 53b through the closing members 54, so that the length of each of the gaps Can be reduced. Therefore, the receptacle connector 1 according to the present invention can reduce the occurrence of radiation to the signal through the side of the rear surface 4b of the insulation part 4 by using the closing members 54. [0050] In addition, the receptacle connector 1 according to the present invention not only can reduce the manufacturing cost by reducing the material cost, while also preventing the manufacturing cost from being reduced when the receptacle connector 1 according to the present invention covers the entire gap between the upper cover 51 and the second blocking member 53b There is an advantage that the ease of the process can be improved.

Although the eight closing members 54 are shown in Fig. 5, the present invention is not limited thereto, and the closing members 54 may be formed by covering all the gaps between the upper cover 51 and the second blocking member 53b . In this case, the closing members 54 may be formed so that a part of them overlap with each other.

Referring to FIGS. 10A and 10B, in the receptacle connector 1 according to another embodiment of the present invention, the first blocking member 53a may include a coupling member 533a (shown in FIG. 10A).

The coupling member 533a is for connecting the shield 3 with the shield main body 530a (shown in Fig. 10A). The joint member 533a may be formed such that one end thereof is connected to the shielding main body 530a and the other end thereof is connected to the shell body 30. The coupling member 533a may be disposed between the shielding body 530a and the shell 3 with reference to the third axial direction (Z-axis direction). The coupling member 533a may be formed between the shield main body 530a and the shell main body 30 located in the lower direction (DD arrow direction, shown in Fig. 2) with respect to the shield main body 530a. The coupling member 533a may be formed in the shielding main body 530a so as to protrude from the shielding main body 530a toward the lower side (DD arrow direction). The coupling member 533a may be formed in the shielding main body 530a so as to cover the rear surface of the insulating portion 4 located in the insertion groove 30a.

Accordingly, the coupling member 533a can reduce the occurrence of radiation to the signal through the rear surface of the insulating portion 4. [

When the first blocking member 53a includes the coupling member 533a, the receptacle connector 1 according to the present invention can improve the fixing force of the coupling member 533a with respect to the shell 3, And may include a first welding member 36 (shown in FIG. 10A). The first welding member 36 is for fixing the shell 3 and the joint member 533a. The first welding member 36 may be formed by laser welding a through hole (not shown) formed between the shell 3 and the joint member 533a.

As shown in FIG. 10A, the first blocking member 53a may include a plurality of the coupling members 533a. The coupling members 533a may be formed on the blocking body 530a so as to be spaced apart from each other along the first axial direction (X-axis direction).

When the first blocking member 53a includes a plurality of the coupling members 533a, the first welding members 36 may be formed in plurality. The first welding members 36 may be spaced from each other along the first axis direction (X-axis direction) to fix each of the joint members 533a to the shell 3. The first welding members 36 may be formed in a number corresponding to the number of the coupling members 533a.

As shown in FIG. 10B, the coupling member 533a may be integrally formed along the first axial direction (X-axis direction). Even when the coupling members 533a are formed in one piece, the first welding members 36 may be formed to be spaced from each other along the first axis direction (X-axis direction). Accordingly, the receptacle connector 1 according to another embodiment of the present invention can secure the joint member 533a to the shell 3 through the plurality of first welding members 36, It is possible to further improve the fixing force of the coupling member 533a.

Although not shown, the coupling member 533a is formed so as to completely cover between the blocking body 530a and the shell body 30 located in the downward direction (DD arrow direction) with respect to the blocking body 530a . In this case, the coupling member 533a can further reduce the generation of radiation for the signal through the rear surface of the insulation part 4a.

1 to 11, a receptacle connector 1 according to the present invention can include a sealing member 6 (shown in Fig. 11).

The sealing member 6 implements a waterproof function. The sealing member 6 may be installed in the shell 3. When the receptacle connector 1 according to the present invention is installed in an electronic apparatus, the sealing member 6 can be prevented from penetrating moisture, dust, etc. by being stuck in a frame (not shown) of the electronic apparatus. Therefore, the receptacle connector 1 according to the present invention can be implemented to have a waterproof function even in relation to the electronic device, thereby contributing to improvement of the waterproof performance of the electronic device. 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 comprise a support member 31 (shown in FIG. 11). The support member 31 is for supporting the sealing member 6. The shell 3 is fixed to the cover 5 such that the support member 31 protrudes from the cover 5 toward the front side 5). ≪ / RTI > The support member 31 can support the sealing member 6 so that the sealing member 6 seals the space between the shell 3 and the electronic device outside 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, a mounting groove 50 (shown in Fig. 11) is located in the portion of the shell 3 projecting from the cover 5. The sealing member 6 may be installed on the sealing member 6 so as to be positioned in the mounting groove 50. The sealing member 6 may be formed to have a length shorter than the length of the installation groove 50 with reference to the second axial direction (Y-axis direction). The sealing member 6 may be installed in the shell 3 such that a part of the installation groove 50 is left in the front (in the arrow direction of the FD) and the rear (in the arrow direction of the BD).

Although not shown, the sealing member 6 may be formed to have a length equal to the length of the mounting groove 50 with reference to the second axial direction (Y-axis direction). That is, the length of the sealing member 6 and the length of the mounting groove 50 may be the same with respect to the second axial direction (Y-axis direction). 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 projecting from the cover 5 in the shell 3. Accordingly, the receptacle connector 1 according to the present invention can further improve the waterproof performance for electronic devices.

The shell 3 may include a projection member 32 (shown in Fig. 11).

The protrusion member 32 may be formed to protrude outward 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 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. When the insertion hole into which the projection member 32 is inserted is formed in the frame, the size of the projection member 32 may be equal to the size of the insertion hole. Accordingly, the protrusion member 32 is inserted into the insertion hole and is brought into close contact with the frame, thereby sealing the outer surface of the shell 3 and the frame. 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 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. The protrusion member 32 may be formed in a different shape as long as the sealing member 6 can be prevented from being displaced forward . The protrusion member 32 may be formed to protrude outward from the end of the support member 31 toward the front (in the arrow direction of the FD).

The sealing member 6 may include a sealing body 61 (shown in Fig. 11) and a first sealing protrusion 62 (shown in Fig. 11).

The sealing body 61 is in contact with the shell 3. The sealing member 6 may be installed in the shell 3 by arranging the sealing body 61 so as to surround 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 have a quadrangular cross section, and may be formed as an overall elliptical annular shape. Although not shown, the sealing body 61 may be formed to have a cross-sectional shape other than a rectangular cross-section as long as it is capable of realizing a water-proof function. In addition, the sealing body 61 may be formed in a shape other than an elliptical annular shape as long as the sealing body 61 can realize a waterproof function.

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

The first sealing protrusion 62 may protrude more than the outer surface of the cover 5 when the sealing member 6 is installed in the shell 3. Accordingly, the first sealing protrusion 62 is elastically compressed as being closely attached to the frame of the electronic apparatus, so that the frame of the electronic apparatus can be pressed by the restoring force. Therefore, the receptacle connector 1 according to the present invention can be realized to have better waterproof performance.

The first sealing protrusions 62 may be formed to be reduced in size as they are protruded from the sealing body 61. For example, the first sealing protrusion 62 may have a trapezoidal cross section. In this case, the first sealing protrusions 62 may have a trapezoidal cross-section, and may have a generally elliptical annular shape. Although not shown, the first sealing protrusion 62 may be formed to have a cross-sectional shape other than a trapezoidal cross-section as long as the waterproof function can be realized. In addition, the first sealing protrusion 62 may be formed in a shape other than an elliptical annular shape as long as the first sealing protrusion 62 is capable of implementing a waterproof function.

Although not shown, the sealing member 6 may include a plurality of the first sealing protrusions 62. In this case, the first sealing protrusions 62 may be formed on the sealing body 61 so as to be spaced from each other along the second axis direction (Y-axis direction).

The sealing member 6 may include a second sealing protrusion 63 (shown in Fig. 2).

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 present invention can reduce the amount of wear of the sealing main body 61 by restricting the rotation of the sealing main body 61 by the second sealing protrusion 63. [0064] 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 51a (shown in Fig. 2). 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 51a. Accordingly, the support groove 51a 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 support groove 51a 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 support groove 51a with respect to the second axial direction (Y-axis direction).

2, the support groove 51a is formed in the upper cover 51, but the present invention is not limited thereto. Therefore, 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. [

The first insulation portion 41 may be positioned forward (FD arrow direction) with respect to the second insulation portion 42.

The first insulation portion 41 may include an insulation body 411 (shown in FIG. 12).

The insulating body 411 is for supporting the contacts 2. The insulating body 411 has an overall appearance of the first insulating portion 41. The first contacts 2a may be coupled to the insulating body 411 such that the connecting members 21 are located on the upper surface of the insulating body 411. [ The second contacts 2b may be coupled to the insulating body 411 such that the connecting members 21 are located on the lower surface of the insulating body 411. [ The connecting members 21 and the connecting members 23 may be coupled to the insulating body 411. The insulating body 411, the first contacts 2a, and the second contacts 2b may be formed to be coupled to each other through insert molding.

The first insulating portion 41 may include a protruding member 412 (shown in FIG. 12).

The protruding member 412 protrudes outward from the insulating main body 411. The protruding member 412 may be coupled to the insulating body 411 so as to protrude outward from the insulating body 411. The protruding member 412 and the insulating body 411 may be integrally formed. The first insulating portion 41 may be inserted and joined to the inside of the shell 3 so that the protruding member 412 contacts the inner surface 31a of the shell 3 as shown in Fig. The protruding member 412 can seal between the inner surface 31a of the shell 3 and the outer surface of the first insulating portion 41. [

The second insulation portion 42 is for supporting the contacts 2. The contacts 2 may be coupled to the second insulation 42 such that the mounting members 22 are at the same height. The mounting members 22 and the connecting members 23 may be coupled to the second insulating portion 42. The second insulation portion 42, the first contacts 2a, and the second contacts 2b may be formed to be coupled to each other through insert molding.

Referring to Fig. 11, the receptacle connector 1 according to the present invention can include a waterproof portion 9 (shown in Fig. 11). The waterproof portion 9 is for realizing a waterproof function. The waterproof portion 9 can seal the space between the outer surface of the insulating portion 4 and the inner surface 31a of the shell 3, thereby realizing a waterproof function. The waterproof portion 9 is formed to partially surround the contacts 2, thereby realizing a waterproof function for the contacts 2. The waterproof portion 9 may be formed by applying a potting liquid to the inside of the shell 3 in a state where the insulation portion 4 is inserted into the shell 3 and then curing.

The receptacle connector 1 according to the present invention is characterized in that the waterproof portion 9 is formed on the rear surface 42a of the second insulation portion 42 (shown in Fig. 12) with respect to the second axial direction (Y axis direction) Between the front surface 41a of the first insulation portion 41 and the rear surface 42a of the second insulation portion 42 and the first insulation portion 41 and the second insulation portion 42, (2) located in a spaced space (S, shown in FIG. 12) between the first and second insulation portions 42, as shown in FIG. That is, in the receptacle connector 1 according to the present invention, the position of the waterproof portion 9 is changed toward the front (in the arrow direction of the FD) when compared with the prior art.

Accordingly, the receptacle connector 1 according to the present invention can prevent the position of the mounting members 22 from being changed due to a change in volume or the like during the process of curing the potting liquid for forming the waterproof portion 9 . Therefore, the receptacle connector 1 according to the present invention can improve the flatness with respect to the mounting members 22, thereby increasing the connecting force between the mounting members 22 and the board, and further, The connection performance between the substrates can be improved.

As the position of the waterproof portion 9 is changed toward the front side (in the direction of the arrow of the FD) through the spaced space S between the first insulation portion 41 and the second insulation portion 42, (9) may be formed at a position spaced away from the mounting members (22) of the contacts (2) toward the front side (FD arrow direction). The waterproof portion 9 is formed so as to surround the connecting members 23 of the contacts 2 located in the spaced space S between the first insulating portion 41 and the second insulating portion 42.

The mid plate 8 is for connecting the first insulation part 41 and the second insulation part 42. The mid plate 8 is connected to the first insulation part 41 and the second insulation part 42 so that the first insulation part 41 and the second insulation part 42 are disposed apart from each other along the second axis direction (41) and the second insulation part (42). The mid plate 8 may be made of a material having a greater adhesive force to the waterproof portion 9 than the first insulation portion 41 and the second insulation portion 42. For example, the mid-plate 8 may be formed of a metal, and the first insulation portion 41 and the second insulation portion 42 may be formed of synthetic resin.

The mid plate 8 is coupled to the first and second insulation portions 41 and 42 so as to be positioned inside the first insulation portion 41 and the second insulation portion 42, . The middle plate 8 is connected to the insulation body 411 so as to be positioned between the connection members 21 disposed on the upper surface of the insulation body 411 and the connection members 21 disposed on the lower surface of the insulation body 411. [ Lt; / RTI > The mid plate 8 and the contacts 2 may be respectively coupled to the first insulation part 41 and the second insulation part 42 through an insert molding.

The waterproof portion 9 is formed in a spaced space S between the first insulation portion 41 and the second insulation portion 42. [ The waterproof portion 9 partially surrounds the contacts 2 and the mid plate 8 in a spaced space S between the first insulation portion 41 and the second insulation portion 42 So that the waterproof function for the contacts 2 can be realized. The waterproof portion 9 is formed on the entire surface of the inner surface 31a of the shell 3 surrounding the spaced space S between the first insulation portion 41 and the second insulation portion 42 So that the spaced space S between the first insulating portion 41 and the second insulating portion 42 can be completely sealed.

Therefore, the receptacle connector 1 according to the present invention can achieve the following operational effects.

[ Lt; / RTI > The meander main body 81 may be formed in a rectangular shape as a whole, but the present invention is not limited thereto and may be formed in any other shape as long as it can reinforce the strength of the insulating main body 411. The meander main body 81 may be formed of a material having a higher strength than the insulation main body 411. For example, the main body 81 may be formed of metal, and the insulation body 411 may be formed of synthetic resin. The meandering main body 81 may be coupled to the insulation body 411 and the protruding member 412, respectively. In this case, a part of the main body 81 may be coupled to the insulating body 411 and a part of the main body 81 may be coupled to the protruding member 412.

The grounding member 83 is for grounding. The grounding member 83 can be grounded through the substrate by being mounted on the substrate.

When the plurality of mid plates 8 are implemented, the contacts 2 may be positioned between the mid plates 8 with respect to the first axial direction (X-axis direction). The contacts 2 may be positioned between the engagement members 84 included in the mid plates 8 with respect to the first axial direction (X-axis direction) in the spaced apart spaces S .

The waterproof portion 9 partially surrounds the contacts 2 and the engagement members 84 in a spaced space S between the first insulation portion 41 and the second insulation portion 42 So that the waterproof function for the contacts 2 can be realized.

The waterproof portion 9 may be formed in a spaced space S between the first insulation portion 41 and the second insulation portion 42 through the following processes.

13, in a state where the insulating main body 411 to which the contacts 2 are coupled is inserted to be inserted into the shell 3, a potting liquid for forming the waterproof portion 9 Is applied to the inside of the shell (3). The receptacle connector 1 according to the present invention is arranged such that the first insulation part 41 and the second insulation part 42 are arranged so as to be spaced apart from each other, Since the potting liquid can be applied to the inside of the shell 3 at all of the lower side, the potting liquid can be more uniformly filled than when the potting liquid is applied only in one of the upper side and the lower side.

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.

In the receptacle connector 1 according to the present invention, the shell body 30 is integrally formed without the seam 34, and the outer surface of the shell 3 is realized without a gap due to the seam 34, It is possible to prevent the possibility that water or the like may permeate through the opening 34. Therefore, the receptacle connector 1 according to the present invention can enhance the waterproof performance.

The shell body 30 may be formed integrally with the plate material by a deep drawing method so that the joint 34 is not present. In this case, the shell body 30 may be integrally formed without the joint 34 through the following process.

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.

Through the above-described processes, the shell body 30 may be integrally formed so as to have no joint 34 as shown in FIGS. 20 and 21. 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. In addition, the receptacle connector 1 according to the present invention can intrinsically block the possibility of penetration of water or the like through the joint 34, thereby enhancing the waterproof performance.

Although not shown, the shell body 30 can be integrally formed using other methods as well as the deep drawing method described above. For example, the shell body 30 may be integrally formed by a process such as a tube forming process, a die casting process, a MIM process, or the like.

The insertion groove 30a is formed through the shell body 30. The insertion groove 30a can function as a connection space in which the plug connector is connected to the contacts 2. The plug connector is moved rearward (in the direction of the arrow of the BD) from the front of the shell 3 (in the direction of the arrow FD) and inserted into the insertion groove 30a so as to be inserted into the contacts 2 located in the insertion groove 30a Can be connected. The insertion groove 30a may serve as an insertion space for accommodating the waterproof portion 9. [ The waterproof portion 9 can be realized by applying the potting liquid to the insertion groove 30a at the rear side of the shell 3 (in the direction of the arrow BD) and then curing. The insertion groove 30a may be formed through a step of processing the plate member 100 by a deep drawing technique.

The insertion groove 30a may be formed to have a smaller size than the protruding member 412. The portion having the maximum cross-sectional area in the protruding member 412 may be formed to have a larger cross-sectional area than the insertion groove 30a, with reference to the X-Z plane formed by the X-axis and the Z-axis. Accordingly, the first insulating portion 41 may be coupled to the shell body 30 in an interference fit manner by using the protruding member 412. Therefore, the receptacle connector 1 according to the present invention can further prevent the leakage of the potting liquid through the clearance between the shell body 30 and the first insulating portion 41, thereby further enhancing the waterproof performance.
