Referring to FIG. 4 , the shell 3 may be formed such that an end 32 (shown in FIG. 4 ) of the support member 31 protrudes outward from the support member 31 . The end 32 may be formed to protrude from the support member 31 at a position spaced from the sealing member 7 toward the front side (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 7 from being separated toward the front side (in the direction of the FD arrow) by using the end 32 . Therefore, in the receptacle connector 1 according to the present invention, the sealing member 7 coupled to the support member 31 is more firmly maintained in a sealed state between the shell 3 and the electronic device. can

Although not shown, the receptacle connector 1 according to the present invention may not be formed so that the end 32 of the support member 31 protrudes outward from the support member 31 . That is, as described above, since the receptacle connector 1 according to the present invention forms the sealing member 7 by applying and curing a sealing material, the sealing member 7 forms the shell 3 and the sealing material. It can be firmly coupled to the plate (6). Therefore, in the receptacle connector 1 according to the present invention, the sealing member 7 moves forward (in the direction of the FD arrow) even when vibration or shaking occurs during the process of inserting and separating the plug connector or the process of using an electronic device. ), it is possible to prevent the sealing member 7 from escaping without additional work of forming the end 32 of the support member 31 so as to protrude.

In this case, the sealing material fills the inside of the receiving groove 62 while flowing by gravity, so that the sealing member 7 is the shell ( 3) is formed to be in contact with the upper surface 3a, lower surface 3b, seat surface 3c, and right surface 3d, respectively, so that the boundary area between the sealing plate 6 and the shell 3 is waterproof function can be improved.

The sealing plate 6 may be formed to protrude more outward from the shell 3 than the sealing member 7 . That is, the length 6H of the sealing plate 6 is formed longer than the lengths 71H and 72H of the sealing member 7 based on the third axial direction (Z-axis direction, shown in FIG. 7). . As described above, in the receptacle connector 1 according to the present invention, the sealing member 7 is formed by applying a sealing material to the front side (in the direction of the FD arrow) of the sealing plate 6 and curing the sealing material. Therefore, in the receptacle connector 1 according to the present invention, in order to prevent the sealing material from overflowing the support surface 61 of the sealing plate 6 in the process of applying the sealing material, the sealing plate 6 is attached to the sealing member. Compared to (7), it is formed to protrude more outward from the shell (3). The length at which the sealing plate 6 protrudes more outward from the shell 3 than the sealing member 7 may be set in consideration of the viscosity of the sealing material forming the sealing member 7 .

The sealing member 7 may be formed to protrude more outward from the shell 3 than the cover 5 . That is, the lengths 71H and 72H of the sealing member 7 relative to the third axial direction (Z-axis direction) are greater than the lengths 51H of the upper cover 51 and the lengths of the lower cover 52 formed longer. Accordingly, the sealing member 7 is elastically compressed as it comes into close contact with the frame of the electronic device, so that the frame of the electronic device can be pressed by a restoring force. Therefore, the receptacle connector 1 according to the present invention can be implemented to have better waterproof performance.

The sealing member 7 may be formed to protrude more outward from the shell 3 on the rear side (direction of arrow BD) compared to the front side (direction of arrow FD). That is, the length 71H of the sealing member 7 formed on the rear side (BD arrow direction) based on the third axial direction (Z-axis direction) is the sealing member 7 formed on the front side (FD arrow direction). ) is formed longer than the length 72H. As another example, the sealing member 7 may be formed such that a length relative to the third axial direction (Z-axis direction) increases toward the rearward direction (BD arrow direction). As such, in the receptacle connector 1 according to the present invention, the sealing member 7 is formed longer on the rear side (in the direction of the BD arrow) supported by the support surface 61 of the sealing plate 6, thereby reducing the sealing The member 7 can be more stably supported by the sealing plate 6 .

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

First, the receptacle connector 1 according to the present invention is characterized in that the sealing member 7 is formed by applying and curing a sealing material such as silicone or urethane. Accordingly, when the receptacle connector 1 according to the present invention is compared to a comparative example in which a ring-shaped (eg, O-ring) sealing member 7 surrounding the outer surface of the shell 3 is coupled to the shell 3 , can improve the waterproof performance of electronic devices.

That is, in the comparative example, the sealing member 7 formed of an elastic material is closely attached to the frame of the electronic device to block penetration of moisture, dust, etc. In this case, the process of inserting and separating the plug connector and the electronic device An external force such as torsion acts on the sealing member 7 due to vibration, shaking, etc. generated in the process of using the device, and the shape of the sealing member 7 is distorted, so that the sealing member 7 moves along the shell 3 A function of sealing between the electronic device and the electronic device may be deteriorated. For this reason, according to the comparative example, deformation of the sealing member 7 may cause a problem in waterproof performance of the electronic device. Unlike this, the receptacle connector 1 according to the present invention has the advantage of improving waterproof performance when compared to the comparative example by forming the sealing member 7 by applying and curing a sealing material.

Third, in the receptacle connector 1 according to the present invention, the sealing member 7 is formed in the boundary area between the sealing plate 6 and the shell 3 by using the receiving groove 62 formed in the sealing plate 6. ) is implemented to form. Accordingly, in the receptacle connector 1 according to the present invention, the sealing member 7 is formed by applying a sealing material to the support surface 61 of the sealing plate 6 without forming the receiving groove 62. Compared to the comparative example, the waterproof function of the boundary area between the sealing plate 6 and the shell 3 can be further improved.

That is, in the comparative example, the shell 3 is erected so that the portion to which the sealing material is applied faces upward, and the sealing material is applied on the sealing plate 6. In this case, due to work tolerances, the sealing plate ( In a state in which 6) is not accurately maintained in a horizontal state, the sealing material may harden in a state in which the boundary area between the sealing plate 6 and the shell 3 is not completely filled. For this reason, according to the comparative example, since the sealing member 7 does not cover the entire surface of the boundary region between the sealing plate 6 and the shell 3, the sealing plate 6 and the shell (3) Moisture can penetrate through the gaps between them. Unlike this, in the receptacle connector 1 according to the present invention, the receiving groove 62 is formed in the sealing plate 6 and the sealing member 7 is formed between the sealing plate 6 and the shell 3. By forming to cover the entire boundary area, there is an advantage in that waterproof performance can be improved when compared to the comparative example.

Specifically, by forming a connecting member between the first insulating part 41 and the second insulating part 42 with a synthetic resin of the same material as these, an integral insulating part 4 having a through area therein can be formed. In this case, since the waterproof part 9 is not strongly adhered to the connection member made of synthetic resin, moisture may penetrate into the gap between the waterproof part 9 and the connection member.

Therefore, in the embodiment of the present invention, the insulating part 4 is implemented to include the first insulating part 41 and the second insulating part 42 as separate components, and the mid plate formed of metal ( 8) is used to connect the first insulating part 41 and the second insulating part 42, and the spaced space S between the first insulating part 41 and the second insulating part 42 By forming the waterproof part 9 on the inside, the waterproof part 9 is strongly adhered to the mid plate 8 to completely prevent moisture permeation, thereby improving the waterproof performance.

Accordingly, the receptacle connector 1 according to the present invention is processed to protrude a part of the shell 3 to the inside of the shell 3, in contrast to the comparative example in which the stopper function for the plug connector is implemented. A stopper function for the plug connector can be implemented without processing the shell 3 . Therefore, in the receptacle connector 1 according to the present invention, when a part of the shell 3 is processed to protrude toward the inside of the shell 3, in contrast to the comparative example in which waterproof performance is deteriorated, the There is an advantage in that a stopper function for the plug connector can be implemented while maintaining waterproof performance. On the other hand, in the comparative example, when a hole is created in the shell 3 as a part of the shell 3 is processed to protrude to the inside of the shell 3, the shell is to block the hole. Additional work is required for (3). In contrast, since the receptacle connector 1 according to the present invention maintains the waterproof performance of the shell 3 without additional work on the shell 3 and at the same time implements a stopper function for the plug connector, When prepared, it has the advantage of reducing the manufacturing cost by reducing the process cost.

Accordingly, the receptacle connector 1 according to the present invention uses at least one of the first insulating member 411 and the blocking member 412 to implement a stopper function for the plug connector. When compared with the comparative example, Abrasion caused by repeated contact with the plug connector may be reduced. Therefore, the receptacle connector 1 according to the present invention has the advantage of extending the service life when compared to the comparative example. For example, the limiting member 81 may be formed of metal, and the first insulating member 411 and the blocking member 412 may be formed of synthetic resin. In this case, since the entire mid plate 8 is made of metal, the limiting member 81 may be made of metal.

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

The receptacle connector 1 according to the present invention prevents movement of the waterproof portion 9 formed to surround the coupling members 84 and the contacts 2, thereby preventing the coupling members 84 and the contacts 2 from moving. ) can further improve the waterproof performance. That is, since the ground members 83 are formed to protrude more inward than the coupling members 84, by supporting the waterproof part 9 from the rear surface of the waterproof part 9, the waterproof part 9 ) can be prevented.

2 to 13 , the waterproof part 9 may be formed in a space S between the first insulating part 41 and the second insulating part 42 . The waterproof part 9 may be formed in the space S between the first insulating part 41 and the second insulating part 42 through the following process.

First, as shown in FIG. 12, in a state in which the first insulating member 411 to which the contacts 2 are coupled is coupled to be inserted into the shell 3, potting for forming the waterproof part 9 is performed. The liquid is applied to the inside of the shell (3). In the receptacle connector 1 according to the embodiment of the present invention, as the first insulating part 41 and the second insulating part 42 are arranged to be spaced apart from each other, the second insulating part 42 with reference to FIG. 12 Since the potting liquid can be applied to the inside of the shell 3 on both the upper and lower sides of the shell 3, the potting liquid can be more uniformly filled compared to the case where the potting liquid is applied only in one direction of the upper and lower sides.

Next, as the potting liquid applied to the inside of the shell 3 flows inside the shell 3, the spaced space between the first insulating part 41 and the second insulating part 42 ( S) is filled. In this case, the shell 3 is in a state where the portion to which the potting liquid is applied faces upward. Accordingly, the potting liquid may flow so as to fill the space S between the first insulating part 41 and the second insulating part 42 by gravity.

Next, as shown in FIG. 13 , when the potting liquid is filled in the space S between the first insulator 41 and the second insulator 42 , the potting liquid is cured. Accordingly, the potting liquid is implemented as the waterproof part 9 .

Through the processes as described above, the waterproof part 9 may be formed to be located in the space S between the first insulating part 41 and the second insulating part 42 .

The waterproof part 9 is the first insulating member 411 of the contacts 2 located in the space S between the first insulating part 41 and the second insulating part 42. Contacts 2 (hereinafter referred to as 'first contact 2a') located on the upper surface and contacts 2 located on the lower surface of the first insulating member 411 (hereinafter referred to as 'second contact 2b') It may be formed in a spaced space S between the first insulating part 41 and the second insulating part 42 so as to surround four surfaces of (referred to as). Accordingly, in the receptacle connector 1 according to the present invention, the waterproof portion 9 is formed to surround each of the four surfaces of the first contacts 2a and the second contacts 2b, so that the Complete waterproofing of the first contact 2a and the second contacts 2b can be realized. Accordingly, the receptacle connector 1 according to the present invention can improve waterproof performance of the first contacts 2a and the second contacts 2b.

The waterproof part 9 may be formed to surround four surfaces of a connecting member 23 (shown in FIG. 10) of each of the first contact 2a and the second contact 2b. Among the first contacts 2a, when there is a portion where the connecting member 23 is bent downward, the waterproof part 9 extends from the connecting member 23 of the first contact 2a in the downward direction. It may be formed to surround four surfaces of a portion spaced from the bent portion toward the front side (in the direction of the FD arrow). Accordingly, in the receptacle connector 1 according to the present invention, the connection member 23 of the first contact 2a is damaged due to a change in volume or the like in the process of curing the potting liquid for forming the waterproof part 9. Since it is possible to prevent pressing the bent portion in the downward direction, the flatness of the first contact 2a with respect to the mounting member 22 can be improved.

When the mid plate 8 includes a plurality of coupling members 84, the first coupling member 84a (shown in FIG. 15) and the second coupling member 84b (shown in FIG. 15) They are arranged at positions spaced apart from each other based on the axial direction (X-axis direction). The first contacts 2a and the second contacts 2b are positioned between the first coupling member 84a and the second coupling member 84b based on the first axial direction (X-axis direction). can do.

2 to 17, the blocking member 412 has a larger size (412D, shown in FIG. 16) than the size (33D, shown in FIG. 16) of the inner surface (31a) of the shell (3). ) can be formed. Accordingly, when the first insulating part 41 is inserted into the shell 3, the blocking member 412 may be compressed by being pressed against the inner surface 31a of the shell 3. Therefore, the blocking member 412 presses the inner surface 31a of the shell 3 with a restoring force, thereby providing sealing force between the inner surface 31a of the shell 3 and the outer surface of the first insulating portion 41. can increase

As shown in FIG. 17, the blocking member 412 protrudes from the top surface 411a, the bottom surface 411b, the left surface 411c, and the right surface 411d of the first insulating member 411, respectively. 1 may be coupled to the insulating member 411. The blocking member 412 protrudes from at least one of the upper surface 411a, the lower surface 411b, the seat surface 411c, and the right surface 411d of the first insulating member 411. may be coupled to.

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

In the receptacle connector 1 according to the present invention, sealing force between the inner surface 31a of the shell 3 and the outer surface of the first insulating portion 41 can be increased by the blocking member 412 . Accordingly, the receptacle connector 1 according to the present invention prevents the waterproof performance from deteriorating as the potting liquid leaks between the inner surface 31a of the shell 3 and the outer surface of the first insulating portion 41. By doing so, it is possible to have excellent waterproof performance.

In addition, even if there is moisture passing through the waterproof part 9 formed by curing the potting liquid, the receptacle connector 1 according to the present invention has the blocking member 412 to restore the inner surface 31a of the shell 3 with restoring force. By pressurizing with , it is possible to block the passage of moisture between the inner surface 31a of the shell 3 and the outer surface of the first insulating part 41 , so that the waterproof performance can be improved.

The blocking member 412 may be formed such that an outer surface to be in contact with the inner surface 31a of the shell 3 forms a curved surface. Accordingly, while the blocking member 412 is inserted into the inside of the shell 3, the inner surface 31a of the shell 3 can be prevented from being damaged by the blocking member 412. Therefore, the receptacle connector 1 according to the present invention can have excellent waterproof performance by preventing the inner surface 31a of the shell 3 from being damaged by the blocking member 412 . In addition, in the receptacle connector 1 according to the present invention, there is a gap between the blocking member 412 and the inner surface 31a of the shell 3 while the blocking member 412 is inserted into the shell 3. By reducing the applied frictional force, the ease of inserting and coupling the first insulating part 41 into the inside of the shell 3 can be improved.

The blocking member 412 may be integrally formed with the first insulating member 411 . The blocking member 412 and the first insulating member 411 may be manufactured separately, and then the blocking member 412 may be coupled to the first insulating member 411 . The blocking member 412 may be formed of the same material as the first insulating member 411 . The blocking member 412 may be formed of a material different from that of the first insulating member 411 . In this case, the blocking member 412 may be formed of a material having heat resistance. For example, the blocking member 412 may be formed of silicon, urethane, or the like.

Referring to FIGS. 2 to 18 , the first insulating portion 41 may include a protruding member 414 (shown in FIG. 18 ).

The protruding member 414 may be formed to protrude outward from the first insulating member 411 . When the first insulating portion 41 includes the protruding member 414 , the blocking member 412 may be coupled to the protruding member 414 so as to protrude outward from the protruding member 414 . Accordingly, the receptacle connector 1 according to the present invention has the advantage of reducing the material cost for the blocking member 412 when the blocking member 412 and the first insulating member 411 are manufactured separately. . The protruding member 414 may be formed in a smaller size (414D, shown in FIG. 18) compared to the size (33D, shown in FIG. 18) of the inner surface 31a of the shell 3. The blocking member 412 protrudes outward from the protruding member 414 to have a larger size (412D, shown in FIG. 16) compared to the size 33D of the inner surface 31a of the shell 3. can be formed For example, the blocking member 412 may be coupled to the protruding member 414 so as to protrude in a radial direction with respect to the protruding member 414 .

The blocking member 412 may be integrally formed with the protruding member 414 and coupled to the protruding member 414 . After the blocking member 412 and the protruding member 414 are manufactured separately, the blocking member 412 may be coupled to the protruding member 414 to be coupled to the protruding member 414 . The blocking member 412 may be formed of the same material as the protruding member 414 . The blocking member 412 may be formed of a material different from that of the protruding member 414 . In this case, the blocking member 412 may be formed of a material having heat resistance. For example, the blocking member 412 may be formed of silicon, urethane, or the like.

Referring to FIGS. 2 to 22 , the shell 3 serves to provide a connection space where the plug connector is connected to the contacts 2 . The plug connector can be connected to the contacts 2 by moving from the front (direction of arrow FD) to the rear (direction of arrow BD) of the shell 3 and being inserted into the shell 3 . The plug connector may be separated from the contacts 2 by moving toward the front (direction of arrow FD) and being separated from the shell 3 .

The shell 3 may support the first insulating part 41 . The first insulating part 41 may be inserted into the shell 3 by moving toward the front side (direction of arrow FD) in a state in which the contacts 2 are coupled. Accordingly, the first insulating part 41 may be coupled to the shell 3 so that the connecting members 21 of the contacts 2 are positioned inside the shell 3 .

The shell 3 may accommodate the waterproof part 9 . The waterproof part 9 may be implemented by curing after a potting liquid is applied to the inside of the shell 3 in a state where the first insulating part 41 is coupled to the shell 3 . In the shell 3, a portion where the plug connector is inserted and a portion where the waterproof part 9 is located may be positioned opposite to each other with respect to the blocking member 412.

The shell 3 may include a shell body 30 (shown in FIG. 20) and a receiving hole 33 (shown in FIG. 20).

The shell body 30 is to protect the contacts 2 located in the receiving hole 33, the waterproof part 9, and the first insulating part 41 from the outside. The shell body 30 may form the overall appearance of the shell 3 . The shell 3 may be formed in the shape of an elliptical rectangle with an empty inside as a whole, but is not limited thereto, and the contacts 2, the waterproof part 9, and the first insulating part 41 are formed on the outside. It may be formed in another form as long as it is in a form that can be protected from.

The shell body 30 is integrally formed without a joint 34 (shown in FIG. 19). Accordingly, the outer surface of the shell 3 is implemented without gaps due to the seam 34 . Accordingly, the receptacle connector 1 according to the present invention can achieve the following operational effects.

First, when the shell 3 is manufactured through a bending process in which a plate material is cut and then bent, and a bonding process in which both ends of the bent plate material are joined through a processing operation such as welding, the shell 3 includes the coupling process. A seam 34 is formed through the process. Since this joint 34 is a gap, it must be filled through a separate additional work such as tapping in implementing a waterproof function. According to this, the shell 3 has a problem in that productivity decreases due to an increase in manufacturing cost and an increase in manufacturing time due to an increase in man-hours. In addition, even if the seam 34 is filled through additional work, the shell 3 has a problem in that it has low waterproof performance because there is a risk of penetration of moisture or the like through the seam 34 .
