Detailed Description

Hereinafter, embodiments of a receptacle connector according to the present invention will be described in detail with reference to the accompanying drawings.

Referring to fig. 2 to 4, the receptacle connector 1 of the present invention is combined with a substrate (not shown) provided in various electronic devices to be connected with a plug connector 200 (shown in fig. 1). The substrate may be a Printed Circuit Board (PCB).

Referring to fig. 2 to 8, the receptacle connector 1 of the present invention includes: the plug connector 200 includes a plurality of contacts 2 for electrically connecting the plug connector 200 to a board coupled to an electronic device, an insulating portion 3 coupled to the plurality of contacts 2, and a housing 4 coupled to the insulating portion 3. The housing 4 includes: a housing body 41 formed with a receiving hole 42 into which the plug connector 200 is inserted; and a restriction portion 43 protruding toward the accommodation hole 42 to restrict a distance that the plug connector 200 can move in an insertion direction into the accommodation hole 42. The housing main body 41 and the restricting portion 43 are integrally formed without a seam. The restricting portion 43 includes a restricting member 431 for supporting the plug connector 200. The restricting member 431 includes: a restricting face 4311 formed as a flat face to support the plug connector 200; a first dispersion surface 4312 connected to the restriction surface 4311; and a second dispersion surface 4313 connected to the regulation surface 4311 at a position spaced apart from the first dispersion surface 4312. The second dispersion surface 4313 and the first dispersion surface 4312 are formed as curved surfaces. Therefore, according to the receptacle connector 1 of the present invention, the following operational effects can be obtained.

First, according to the receptacle connector 1 of the present invention, the housing main body 41 and the restricting portion 43 are integrally formed without a seam. Therefore, in the process of manufacturing the restricting portion 43, the socket connector 1 of the present invention can fundamentally block the possibility of penetration of moisture or the like, thereby improving the waterproof performance, as compared with the prior art in which the space 150 (shown in fig. 1) is formed between the housing main body 41 and the restricting portion 43. Further, the receptacle connector 1 of the present invention does not require additional work such as knocking for closing the space 150, and therefore, not only can the manufacturing cost be saved by reducing the number of working hours required for providing the waterproof function, but also the productivity can be improved by shortening the manufacturing time.

Second, according to the receptacle connector 1 of the present invention, if the plug connector 200 is supported by the restricting surface 4311 during the insertion into the receiving hole 42, it does not move further in the insertion direction (ID arrow direction). Therefore, according to the receptacle connector 1 of the present invention, the restriction member 431 restricts the distance that the plug connector 200 can move in the insertion direction (ID arrow direction) when inserted into the accommodation hole 42, so that the insulation portion 3 can be prevented from being damaged or broken or the waterproof performance can be prevented from being lowered when the plug connector 200 is inserted into the accommodation hole 42 at an excessively large depth.

Thirdly, according to the receptacle connector 1 of the present invention, the restricting member 431 includes dispersing

surfaces

4312, 4313 formed as curved surfaces in addition to the restricting surface 4311. When the plug connector 200 is inserted into the receiving hole 42 and supported by the restricting surface 4311, the dispersing

surfaces

4312, 4313 may contact different portions of the plug connector 200. Therefore, the dispersion surface can disperse the stress applied to the restricting member 431 during the insertion of the plug connector 200 into the receiving hole 42. Therefore, compared to the prior art in which stress is concentrated on the restricting member 431, the receptacle connector 1 of the present invention reduces the possibility of damage or breakage of the restricting member 431 by the dispersing

surfaces

4312 and 4313, so that the life cycle of the housing 4 can be increased, and the maintenance cost can also be reduced.

Hereinafter, the contact 2, the insulating portion 3, and the housing 4 will be described in detail with reference to the drawings.

Referring to fig. 2 to 4 and 7, the contacts 2 are used to electrically connect the plug connector 200 and the substrate. The contact 2 is connected to a plug connector 200 inserted into the housing 4 in a state of being mounted on the board, so that the plug connector 200 and the board can be electrically connected. The contact 2 may be formed of a material having electrical conductivity. The contact 2 may be combined with the insulating part 3. A plurality of the contacts 2 may be coupled to the insulating portion 3.

Referring to fig. 7, each of the plurality of contacts 2 may include a connection member 21 and a mounting member 22.

The connecting member 21 is used for connecting with the plug connector 200. A part of the plurality of contacts 2 may be coupled to the insulating part 3 such that the connecting member 21 is located on one surface of the insulating part 3. The plurality of connecting members 21 positioned on one surface of the insulating portion 3 may be arranged at intervals along the first axial direction (X-axis direction). The remaining part of the plurality of contacts 2 may be coupled to the insulating part 3 in such a manner that the connecting member 21 is located on the other surface of the insulating part 3. The plurality of connecting members 21 located on the other surface of the insulating portion 3 may be arranged at intervals along the first axial direction (X-axis direction). One surface and the other surface of the insulating portion 3 are opposite surfaces to each other. One surface of the insulating part 3 may be an upper surface of the insulating part 3. The other surface of the insulating portion 3 may be a lower surface of the insulating portion 3. The first axial direction (X-axis direction) may be an axial direction perpendicular to the insertion direction (ID arrow direction).

The mounting member 22 is for mounting to the substrate. The plurality of contacts 2 can electrically connect the plug connector 200 and the board as the plug connector 200 is connected to the connecting member 21 in a state where the mounting members 22 are mounted on the board. In this case, the plug connector 200 connected with the connecting member 21 may be electrically connected with the substrate via the mounting member 22.

Referring to fig. 2 to 4, 7, 8, and 9 to 11, the plurality of contacts 2 are coupled to the insulating portion 3. The insulating portion 3 supports the plurality of contacts 2. The plurality of contacts 2 can be supported by the insulating portion 3 in conjunction with the insulating portion 3. The plurality of contacts 2 may be coupled to the upper and lower surfaces of the insulating part 3, respectively. The insulating portion 3 may be inserted into and coupled to the housing 4 such that the plurality of connecting members 21 are positioned inside the housing 4. In this case, a part of the plurality of connecting members 21 may be located outside the housing 4. The insulating portion 3 may be inserted into and coupled to the housing 4 such that the plurality of mounting members 22 are positioned outside the housing 4. The insulating portion 3 may be formed of an insulating material such as rubber.

Referring to fig. 4 and 7, the insulating part 3 may include a first insulating member 31 and a second insulating member 32.

The first insulating member 31 serves to support the plurality of contacts 2. The first insulating member 31 forms the entire appearance of the insulating portion 3. A part of the plurality of contacts 2 may be coupled to the first insulating member 31 in such a manner that the plurality of connecting members 21 are located on the upper surface of the first insulating member 31. A part of the plurality of contacts 2 may be coupled to the first insulating member 31 in such a manner that the plurality of connecting members 21 are located on the lower surface of the first insulating member 31. The first insulating member 31 and the plurality of contacts 2 may be coupled to each other by Insert Molding (Insert Molding).

The second insulating member 32 serves to support the plurality of contacts 2. The second insulating member 32 and the first insulating member 31 may be arranged to be spaced apart from each other along the second axis direction (Y-axis direction). The second axis direction (Y-axis direction) and the first axis direction (X-axis direction) are axis directions perpendicular to each other on a horizontal plane. The second insulating member 32 may be disposed on the insertion direction (ID arrow direction) side with respect to the first insulating member 31 in a state where the insulating portion 3 is inserted inside the housing 4. The plurality of contacts 2 may be combined with the second insulating member 32 in such a manner that the plurality of mounting members 22 are located at the same height. The second insulating member 32 and the plurality of contacts 2 may be implemented to be coupled to each other by Insert Molding (Insert Molding).

Referring to fig. 7, the insulating part 3 may include an opposite surface 33.

The opposing surface 33 is a surface of the insulating portion 3 facing the separating direction (SD arrow direction). The opposing surface 33 may face the plug connector 200 side in a state where the plug connector 200 is inserted into the housing 4. The opposing surface 33 may be formed on the first insulating member 31. The opposing surface 33 may be one surface of the first insulating member 31 facing the separation direction (SD arrow direction). The separating direction (SD arrow direction) and the inserting direction (ID arrow direction) may be directions parallel and opposite to each other with respect to the second axis direction (Y axis direction).

The opposing face 33 may be disposed to be spaced apart from an insertion reference face IF (shown in fig. 7) by a first spacing distance D1 (shown in fig. 7) with reference to the second axis direction (Y axis direction). The insertion reference plane IF is formed at an end of the housing 4 where the plug connector 200 starts to be inserted. The insertion reference plane IF may be formed in a direction parallel to the third axis direction (Z axis direction). The third axis direction (Z axis direction) corresponds to the direction perpendicular to the first axis direction (X axis direction) and the second axis direction (Y axis direction) respectively, and may correspond to the direction the same as the direction in which the total height of the receptacle connector 1 of the present invention is increased or decreased.

Referring to fig. 2 to 17, the housing 4 provides a connection space for connecting the plug connector 200 to the plurality of contacts 2. The plug connector 200 is moved in an insertion direction (ID arrow direction) and inserted into the inside of the housing 4 to be connected with the plurality of contacts 2. When the receptacle connector 1 of the present invention corresponds to the USB Type-C specification, the plug connector 200 may be connected to a part of the plurality of contacts 2. The plug connector 200 is moved to the separation direction (SD arrow direction) to be disengaged from the housing 4 so as to be separable from the plurality of contacts 2.

The housing 4 may support the insulating part 3. The insulating portion 3 is inserted into the housing 4 so as to be movable in the separation direction (SD arrow direction) in a state of being coupled to the plurality of contacts 2. The housing 4 may be formed of a metal material.

The housing 4 may include the housing main body 41 and the receiving hole 42.

The housing body 41 protects the plurality of contacts 2 and the insulating portion 3 located in the accommodation hole 42 from the outside. The housing main body 41 may form an overall appearance of the housing 4. The housing body 41 may be formed in a rectangular parallelepiped shape having an oval shape with an inner side being hollow as a whole, but is not limited thereto, and may be formed in other shapes as long as the plurality of contacts 2 and the insulating portion 3 can be protected from the outside.

The housing body 41 may be integrally formed without seams. Therefore, the outer surface 4a (shown in fig. 7) of the housing 4 may not have a gap formed by a seam. Therefore, compared to the prior art in which the joint needs to be closed by additional work such as knocking as shown in fig. 1A and 1B, the receptacle connector 1 of the present invention can provide the housing 4 with a waterproof function even without the additional work. Therefore, compared with the comparative example, the receptacle connector 1 of the present invention can reduce the manufacturing cost by reducing the number of working steps, and can improve the productivity by shortening the manufacturing time. Further, unlike the comparative example in which moisture or the like may permeate through the joint, the receptacle connector 1 of the present invention can fundamentally block the possibility of moisture or the like permeating through the joint, and therefore, the waterproof performance can be enhanced as compared with the comparative example.

The sheet material may be processed by a Deep Drawing (Deep Drawing) process so that the case main body 41 is integrally formed without seams. In this case, the housing main body 41 may be integrally formed to be seamless by the following process.

First, as shown in fig. 6, in a state where the processing mechanism 20 is in contact with one surface of the plate material 10, the processing mechanism 20 is lowered to a position spaced apart from the other surface of the plate material 10 by a predetermined distance, thereby partially elongating the plate material 10. Thus, a closed-sided processing portion 30 is formed on the sheet material 10. The processing mechanism 20 is provided in a processing device, and may be a punch provided in a punching device, for example. The processing mechanism 20 is formed in a shape corresponding to the housing main body 41. For example, the processing mechanism 20 may be formed in an elliptical rectangular parallelepiped shape. Although not shown in the drawings, the sheet material 10 may be in a state of being supported by a die of a press apparatus.

Then, when a closed-sided processing portion 30 is formed by the processing mechanism 20, the processing mechanism 20 can be separated from the plate material.

Then, one side surface of the processed portion 30 is cut so that one side surface of the processed portion 30 is opened. In this case, when the working mechanism 20 partially elongates the plate material 10, the other side surface of the working portion 30 opposite to the one side surface may be formed in an open shape. That is, when the processing means 20 contacting one surface of the plate material 10 is lowered to partially elongate the plate material 10, the processed portion 30 having the other side surface opened and the one side surface closed can be formed. Therefore, when one side surface of the processed portion 30 is cut and opened, the processed portion 30 is formed in a seamless manner with both side surfaces opened, and the housing main body 41 can be manufactured. In this case, a step of performing a partial cutting process on the other side surface of the processed portion 30 may be performed.

As shown in fig. 5, the housing body 41 can be integrally formed to be seamless by the above-described steps. Therefore, compared with the comparative example, the receptacle connector 1 of the present invention can reduce the number of working steps and provide a waterproof function, thereby reducing the manufacturing cost and improving the productivity by shortening the manufacturing time. Further, the socket connector 1 of the present invention can fundamentally block the possibility of moisture or the like penetrating through the joint, and therefore, the waterproof performance can be enhanced as compared with the comparative example.

The receiving hole 42 is formed through the housing body 41. The receiving hole 42 may serve as a connection space for the plug connector 200 to be connected to the plurality of contacts 2. The plug connector 200 is movable toward the insertion direction (ID arrow direction) and inserted into the accommodation hole 42 so as to be connected to the plurality of contacts 2 located in the accommodation hole 42. The receiving hole 42 may be formed by a process of processing the plate material by a deep drawing process. The receiving hole 42 may be formed in an oval rectangular parallelepiped shape as a whole, but is not limited thereto, and may be formed in another shape as long as it is a connection space in which the plug connector 200 can be connected to the plurality of contacts 2.

Referring to fig. 3, 5, and 7 to 13, the restricting portion 43 is configured to support the plug connector 200 inserted into the receiving hole 42. The restricting portion 43 is formed to protrude toward the accommodating hole 42 side. Therefore, if the plug connector 200 is supported by the restricting portion 43 while being inserted into the receiving hole 42 while being moved in the insertion direction (ID arrow direction), it cannot be moved further in the insertion direction (ID arrow direction). Therefore, the restriction portion 43 restricts the distance that the plug connector 200 can be inserted into the accommodation hole 42 and moved in the insertion direction (ID arrow direction), thereby preventing the insulation portion 3 from being damaged or broken or having a low waterproof performance due to the plug connector 200 being inserted into the accommodation hole 42 at an excessively large depth.

The restricting portion 43 and the case main body 41 may be integrally formed without a seam. Therefore, even if the restricting portion 43 is provided, the outer face 4a of the housing 4 may not have a gap formed by a seam. Therefore, the socket connector 1 of the present invention can fundamentally block the possibility of penetration of moisture or the like via the joint, thereby not only strengthening the waterproof function, but also preventing the plug connector from being inserted with an excessively large depth to extend the service life. The restriction portion 43 may be formed during the process of processing the case main body 41 by a deep drawing process. When the restricting portion 43 is formed, a Groove (Groove) may be formed in the outer face 4a of the housing 4.

Referring to fig. 7 and 8, the restricting part 43 may include a restricting member 431. The restricting member 431 supports the plug connector 200 inserted into the receiving hole 42. The restricting member 431 may support the plug connector 200 when contacting the plug connector 200. When the plug connector 200 is in contact with the restriction member 431, the plug connector 200 may be supported by the restriction member 431 such that the plug connector 200 cannot be further moved toward the insertion direction (ID arrow direction). The restricting member 431 may be formed to protrude toward the accommodating hole 42 side.

The restricting member 431 may extend from an inner surface 4b (shown in fig. 7) of the housing 4 to a lower surface of the insulating part 3 with reference to the third axis direction (Z axis direction). Therefore, the receptacle connector 1 of the present invention increases the restriction area of the restricting member 431 with respect to the third axial direction (Z-axis direction) for restricting the movement of the plug connector 200, so that the restricting force of the restricting member 431 can be increased. The inner surface 4b of the housing 4 corresponds to a surface of the housing 4 facing the accommodation hole 42, and may correspond to a surface opposite to the outer surface 4a of the housing 4.

Referring to fig. 8, the restricting member 431 may include: a limiting surface 4311, a first dispersing surface 4312, and a second dispersing surface 4313.

The restricting face 4311 functions to support the plug connector 200. The restricting face 4311 is formed in a flat surface, and can restrict movement of the plug connector 200 in the insertion direction (ID arrow direction) as it comes into contact with the plug connector 200. Therefore, the receptacle connector 1 of the present invention can apply the restriction force for restricting the movement of the plug connector 200 by using the restriction surface 4311. The limiting face 4311 is interposed between the first dispersion face 4312 and the second dispersion face 4313, and may be connected to each of the first dispersion face 4312 and the second dispersion face 4313. The restricting surface 4311 may be a surface of the restricting member 431 facing the separating direction (SD arrow direction).

The restricting surface 4311 may be disposed apart from the insertion reference surface IF by a second spacing distance D with reference to the second axis direction (Y axis direction). In this case, the restriction surface 4311 and the opposing surface 33 may be spaced apart from the insertion reference surface IF by the same spacing distance as each other with reference to the second axis direction (Y axis direction). That is, since the second spacing distance D2 and the first spacing distance D1 have the same value, the restricting surface 4311 can be arranged on the same line as the opposing surface 33 with respect to the second axis direction (Y axis direction). Therefore, according to the receptacle connector 1 of the present invention, the following operational effects can be obtained.

First, in the receptacle connector 1 according to the present invention, the plug connector 200 is simultaneously contacted with the restriction surface 4311 and the opposing surface 33 in the process of being inserted into the housing 4, so that the restriction surface 4311 and the opposing surface 33 together bear the pressing force caused by the insertion of the plug connector 200. Therefore, compared with the case where the pressing force of the plug connector 200 is received only by the opposing surface 33, the receptacle connector 1 of the present invention can disperse the pressing force, and thus can reduce the possibility that the opposing surface 33 is damaged or broken due to the pressing force.

Second, in the receptacle connector 1 according to the present invention, the plug connector 200 may press the opposite surface 33 in the process of being inserted into the housing 4, and then the plug connector 200 is supported by the restricting member 431, so that the plug connector 200 cannot be further moved to the insertion direction (ID arrow direction). Therefore, the receptacle connector 1 of the present invention prevents the opposite surface 33 from being damaged or broken due to the plug connector 200 continuing to move in the insertion direction (ID arrow direction), and thus can prolong the service life of the insulating portion 3. Further, the receptacle connector 1 of the present invention prevents the pressing force of the plug connector 200 from concentrating on the insulating portion 3 formed of a material having a relatively weaker strength than the housing 4, whereby the service life of the insulating portion 3 can be further extended.

The first dispersion surface 4312 is connected to the restriction surface 4311. The first dispersion surface 4312 is formed in a curved surface to function to disperse the stress applied to the restricting member 431. When the first dispersion surface 4312 is in contact with the plug connector 200, stress applied to the restricting member 431 can be dispersed. Therefore, in comparison with the prior art in which stress is concentrated on the restricting member 431, the receptacle connector 1 of the present invention can realize a dispersing force that disperses stress applied to the restricting member 431 by using the first dispersing surface 4312. The first dispersion surface 4312 may be connected to the limiting surface 4311 at one side of the limiting surface 4311. The first dispersion face 4312 is connected to the inner surface 4b of the housing 4 and the restricting face 4311, respectively.

The restricting surface 4311 connected to the first dispersion surface 4312 may form a right angle with the inner surface 4b of the housing 4. That is, the restricting surface 4311 may be connected to the first dispersion surface 4312 at 90 degrees to the inner surface 4b of the housing 4. Therefore, the receptacle connector 1 of the present invention can improve the stability of the operation in which the restricting surface 4311 supports the plug connector 200. This is because, in the comparative example in which the restriction surface 4311 is connected to the first dispersion surface 4312 so as to be inclined with respect to the inner surface 4b of the housing 4, the plug connector 200 may move in the insertion direction (ID arrow direction) along the restriction surface 4311 during the insertion into the accommodation hole 42. Therefore, in the receptacle connector 1 of the present invention, the restricting surface 4311 forms 90 degrees with the inner surface 4b of the housing 4, so that the restricting force of the restricting surface 4311 for restricting the movable distance of the plug connector 200 can be increased. The inner surface 4b of the housing 4 may be formed parallel to the insertion direction (ID arrow direction).

The second dispersion surface 4313 is connected to the restriction surface 4311 at a position spaced apart from the first dispersion surface 4312. The second dispersion surface 4313 is formed in a curved surface to function to disperse stress applied to the restricting member 431. When the second dispersion surface 4313 comes into contact with the plug connector 200, stress applied to the restricting member 431 can be dispersed. Therefore, in comparison with the prior art in which stress is concentrated on the restricting member 431, the receptacle connector 1 of the present invention can realize a dispersing force for dispersing the stress applied to the restricting member 431 by using the second dispersing surface 4312. The second dispersion surface 4313 may be connected to the restriction surface 4311 at the other side of the restriction surface 4311. The second dispersion surface 4313, the first dispersion surface 4312, and the limiting surface 4311 may be connected to each other without an edge.

The second dispersion surface 4313, the first dispersion surface 4312, and the regulation surface 4311 are continuously formed. Therefore, the receptacle connector 1 of the present invention can sufficiently ensure the thickness 431D (shown in fig. 8) of the restricting member 431 for restricting the movement of the plug connector 200. In the process of forming the restricting member 431 of the related art, since only the thickness of the housing body 41 corresponds to the thickness 431D of the restricting member 431, there is a limit to increase the thickness 431D of the restricting member 431. In the receptacle connector 1 according to the present invention, the second dispersion surface 4313, the first dispersion surface 4312, and the restriction surface 4311 are seamlessly connected as a continuous surface, so that the thickness 431D of the restriction member 431 can be increased. Therefore, the receptacle connector 1 of the present invention can improve the restricting force of the restricting member 431 for restricting the movement of the plug connector 200. The thickness 431D of the restricting member 431 may correspond to a length of the restricting member 431 with reference to the third axis direction (Z axis direction).

The second dispersion face 4313 and the first dispersion face 4312 may contact different portions of the plug connector 200. Therefore, the receptacle connector 1 of the present invention enlarges the region in which the stress can be dispersed by the dispersing

surfaces

4312 and 4313, and the possibility of damage or breakage of the restricting member 431 can be further reduced.

Referring to fig. 7 and 8, the restricting portion 43 may include a rear member 432.

The rear member 432 is combined with the restricting member 431. The rear member 432 and the restricting member 431 may be integrally formed without a seam. The rear member 432 may be disposed at a rear side of the restricting member 431 to provide the restricting member 431 with a supporting force for supporting the plug connector 200. Thus, the rear member 432 supports the restricting member 431 from the rear, so that the restricting member 431 sufficiently exerts a restricting force to restrict the movable distance of the plug connector 200. The rear member 432 may be formed to extend along the insertion direction (ID arrow direction). The rear member 432 may extend in a direction parallel to the second axis direction (Y-axis direction). The rear may correspond to the same direction as the insertion direction (ID arrow direction).

The rear member 432 may be formed to extend from the restricting member 431 to the other end of the housing main body 41. Therefore, the receptacle connector 1 of the present invention increases the area of the rear member 432, so that the supporting force of the rear member 432 for supporting the restricting member 431 from the rear can be increased. Therefore, the receptacle connector 1 of the present invention can improve the stability of the work of supporting the plug connector 200 by the restricting member 431 by increasing the supporting force of the rear member 432 supporting the restricting member 431. One end and the other end of the housing 4 may be different portions of the housing 4 disposed at positions opposite to each other.

Referring to fig. 2 to 11, when the housing 4 includes the restriction part 43, the insulation part 3 may include a clipping groove 34 (shown in fig. 9).

The restricting portion 43 is inserted into the clip groove 34. When the restriction portion 43 is inserted into the clipping groove 34, the insulation portion 3 can clip the housing 4. Therefore, the restricting portion 43 can have a stopper function of restricting a distance by which the plug connector 200 is movable in the insertion direction (ID arrow direction) while having a fixing function of fixing the insulating portion 3 to the housing 4. The clamping groove 34 may be formed to have a predetermined depth from the lower surface of the first insulating member 31.

The clamping groove 34 may be formed in a size corresponding to the restriction portion 43. The clipping groove 34 may have a smaller size than the restriction portion 43. For example, the sandwiching groove 34 may have a smaller sectional area than the restricting portion 43 with reference to a vertical section perpendicular to both the first axis direction (X axis direction) and the second axis direction (Y axis direction). Therefore, as the insulating part 3 is inserted into the accommodating hole 42 such that the restricting part 43 is inserted into the clipping groove 34, the insulating part 3 and the housing 4 can be combined in an interference fit manner. Therefore, the receptacle connector 1 of the present invention is implemented to block the gap between the housing 4 and the insulating portion 3 from the liquid, solid, or the like, so that the waterproof function can be further enhanced. In the process of inserting the insulating part 3 into the accommodating hole 42, a part of the restricting part 43 may be further embedded in the insulating part 3, so that the insulating part 3 may be more firmly combined with the housing 4. The clip groove 34 may be disposed at a portion where the rear member 432 is formed with reference to the second axis direction (Y axis direction).

Referring to fig. 4, 7, 9 to 11, the receptacle connector 1 of the present invention may include a waterproof portion 5.

The waterproof portion 5 achieves a waterproof function by sealing between the outer surface of the insulating portion 3 and the inner surface 4b of the housing 4. The waterproof portion 5 may be formed to surround a portion of the plurality of contacts 2 located outside the insulating portion 3 inside the housing 4, thereby also achieving a waterproof function for the plurality of contacts 2. The waterproof portion 5 may be located at the other end of the housing 4.

The waterproof portion 5 may be formed by applying a coating liquid to the inside of the case 4 in a state where the insulating portion 3 is inserted into the inside of the case 4 and then curing. The waterproof portion 5 may be disposed at a portion where the restriction portion 43 is formed. Therefore, the volume of the coating liquid to be filled inside the housing 4 can be reduced by the restricting portion 43 with respect to the vertical cross section. Therefore, the receptacle connector 1 of the present invention can reduce the amount of coating liquid required to realize the waterproof portion 5, so that the manufacturing cost for realizing the waterproof portion 5 can be reduced. The waterproof portion 5 may be disposed on the rear side with respect to the insulating portion 3. Fig. 11 is a comparative example not including the regulating portion 43, schematically showing an increase area IA of the coating liquid to be filled in the inside of the housing 4.

The flashing 5 may comprise a reduction groove 51 (shown in fig. 9). The reducing groove 51 reduces a coating liquid for forming the waterproof portion 5. The restricting member 431 is formed to protrude toward the accommodating hole 42 side, and therefore, when the package is cured inside the housing 4, the reducing groove 51 may be formed. The reduction groove 51 may be formed in a size corresponding to the restriction portion 43. The reduction groove 51 may be formed to have a size corresponding to the restriction portion 43 with reference to the vertical section. The reduction groove 51 may be disposed at a portion where the rear member 432 is formed with reference to the second axis direction (X axis direction). The reducing groove 51 may be formed to have a predetermined depth from the lower surface of the waterproof body 50. The waterproof body 50 may form an overall appearance of the waterproof portion 5.

Hereinafter, two kinds of embodiments of the restricting portion 43 in the receptacle connector 1 according to the modified example of the present invention will be described in order. The restricting portion 43 of the receptacle connector 1 according to the modified example of the present invention is implemented in substantially the same manner as the restricting portion 43 of the receptacle connector 1 of the present invention described above, and therefore, the point of difference is mainly described below.

< first embodiment >

Referring to fig. 12, the plurality of restricting portions 43 may protrude toward the accommodating hole 42. Fig. 12 shows that two restricting

portions

43a, 43b project toward the accommodating hole 42, but this is merely exemplary, and three or more restricting portions 43 may be formed to project toward the accommodating hole 42. The two restricting

portions

43a, 43b may protrude toward the accommodating hole 42 side at one side portion and the other side portion of the accommodating hole 42, respectively. One side portion of the receiving hole 42 and the other side portion of the receiving hole 42 may be portions spaced apart from each other centering on a middle portion of the housing 4 based on the first axis direction (X-axis direction). When the plurality of restricting portions 43 protrude toward the accommodating hole 42 side, the plurality of restricting members 431 and the plurality of rear members 432 may protrude toward the accommodating hole 42 side.

When the plurality of restricting

portions

43a, 43b protrude toward the accommodating hole 42 side, the plurality of restricting members 431 may support different portions of the plug connector 200 at positions spaced apart from each other to restrict a movable distance of the plug connector. Therefore, the receptacle connector 1 according to the modified example of the present invention can obtain the following operational effects.

First, in the receptacle connector 1 according to the modification of the present invention, the area of the restricting surface 4311 for supporting the plug connector 200 by the plurality of restricting

portions

43a and 43b can be increased. Therefore, the receptacle connector 1 according to the modified example of the present invention can increase the restriction force of the restriction surface 4311 for restricting the movable distance of the plug connector 200.

Secondly, in the receptacle connector 1 according to the modified example of the present invention, in the process of inserting the plug connector 200 into the receiving hole 42, even if the plug connector 200 is inserted obliquely with respect to the insertion direction (ID arrow direction), the plug connector 200 can be guided by the plurality of restricting

portions

43a, 43b to be inserted in the direction parallel to the insertion direction (ID arrow direction). The specific description thereof is as follows. For ease of understanding, any one of the plurality of restricting

portions

43a, 43b will be described as a first restricting portion 43a, and the other restricting portion will be described as a second restricting portion 43 b.

When the plug connector 200 is inserted into the accommodation hole 42 obliquely with respect to the insertion direction (ID arrow direction), one side of the plug connector 200 may first contact the first restriction portion 43 a. In this case, one side of the plug connector 200 is supported by the first restricting portion 43a and cannot be further moved in the insertion direction (ID arrow direction). If one side of the plug connector 200 continues to be inserted into the plug connector 200 in the insertion direction (ID arrow direction) in a state where the one side of the plug connector 200 is supported by the first restriction portion 43a, the other side of the plug connector 200 can be moved so as to be inserted in a direction parallel to the insertion direction (ID arrow direction) and is supported by the second restriction portion 43 b. Therefore, one side and the other side of the plug connector 200 may be supported by the plurality of restricting

portions

43a, 43b, respectively, to restrict a distance by which the plug connector 200 can move. As described above, in the receptacle connector 1 according to the modified example of the present invention, even if the plug connector 200 is inserted obliquely with respect to the insertion direction (ID arrow direction) due to carelessness of an operator or the like in the process of inserting the plug connector 200 into the accommodation hole 42, the plug connector 200 can be guided by the plurality of restricting

portions

43a, 43b to be inserted in the direction parallel to the insertion direction (ID arrow direction). Therefore, in the receptacle connector 1 according to the modification of the present invention, the ease of the work of inserting the plug connector 200 into the receiving hole 42 can be improved.

Thirdly, in the receptacle connector 1 according to the modified example of the present invention, since the portion where the restricting portion 43 is formed is added to the inside of the housing 4, the volume of the coating liquid to be filled in the inside of the housing 4 can be reduced. That is, the receptacle connector 1 according to the modification of the present invention can reduce the increase area IA shown in fig. 11. Therefore, the receptacle connector 1 according to the modification of the present invention can reduce the amount of the coating liquid for realizing the waterproof portion 5, and can reduce the manufacturing cost for realizing the waterproof portion 5.

< second embodiment >

Referring to fig. 13, the restriction portion 43 may be formed to extend along the first axial direction (X-axis direction). The restricting portion 43 may extend from one side portion to the other side portion of the receiving hole 42.

When the restriction part 43 extends in the first axis direction (X-axis direction), the restriction member 431 may support each of one side and the other side of the plug connector 200 to restrict a distance that the plug connector 200 can move. Therefore, the receptacle connector 1 according to the modified example of the present invention can obtain the following operational effects.

First, according to the receptacle connector 1 of the modification of the present invention, the area of the restricting surface 4311 supporting the plug connector 200 can be increased by the restricting portion 43 extending in the first axis direction (X axis direction). Therefore, according to the receptacle connector 1 of the modified example of the present invention, the restriction force of the restriction surface 4311 for restricting the movable distance of the plug connector 200 can be increased.

Second, according to the receptacle connector 1 of the modification of the present invention, even if the plug connector 200 is inserted obliquely with respect to the insertion direction (ID arrow direction) due to carelessness of an operator, a malfunction, or the like in the process of inserting the plug connector 200 into the accommodation hole 42, the plug connector 200 can be guided to be inserted in the direction parallel to the insertion direction (ID arrow direction) by the restricting portion 43 extending in the first axis direction (X axis direction). Therefore, the receptacle connector 1 according to the modified example of the present invention can improve the ease of the work of inserting the plug connector 200 into the receiving hole 42.

Third, according to the receptacle connector 1 of the modified example of the present invention, since the portion where the restricting portion 43 is formed is added to the inside of the housing 4, the volume of the coating liquid to be filled in the inside of the housing 4 can be reduced. Therefore, the socket connector 1 according to the modified example of the present invention can reduce the amount of the coating liquid for realizing the waterproof portion 5, and can reduce the manufacturing cost for realizing the waterproof portion 5.

Referring to fig. 2 to 4, 14 and 16, the receptacle connector 1 of the present invention may include a housing 6.

The cover 6 serves to protect the housing 4. The cover 6 is bonded to the housing 4 to surround the outer surface 4a of the housing 4. The housing 4 may be coupled to the housing 6 in such a manner as to be located inside the housing 6. The cover 6 may be fixedly coupled to the substrate. The cover 6 is mounted on the substrate by surface Mount Technology (surface Mount Technology), and is thereby fixedly bonded to the substrate. The cover 6 may be fixedly coupled to the substrate by inserting fastening members (not shown), such as bolts, into the coupling holes 6A (shown in fig. 2 and 3). The cover 6 and the housing 4 may be joined by partially welding. The housing 4 may be provided to the cover 6 in such a manner as to protrude from the cover 6.

The housing 6 may include an upper housing 61 (shown in fig. 4) and a lower housing 62 (shown in fig. 4).

The upper cover 61 serves to protect the housing 4 at the upper surface of the housing 4. The lower cover 62 is used to protect the housing 4 at the lower surface of the housing 4. The upper surface of the shell 4 may refer to a surface opposite to the surface on which the socket connector 1 is combined with the substrate, and the lower surface of the shell 4 may refer to a surface on which the socket connector 1 is combined with another surface of the substrate, but the invention is not limited thereto.

Therefore, according to the receptacle connector 1 of the present invention, the following operational effects can be obtained.

According to the receptacle connector 1 of the present invention, the housing 6 includes the upper housing 61 and the lower housing 62, instead of being formed in one piece. Therefore, compared with the comparative example in which the cover 6 is formed in one piece and is coupled to the housing 4, the socket connector 1 according to the present invention has the advantage that the process cost can be reduced by reducing the fraction defective of the product.

That is, in the comparative example, the cover 6 formed in one piece is joined to the housing 4 so as to be positioned outside the housing 4, and in this case, if the cover 6 is not formed in a correct size capable of surrounding the outer surface 4a of the housing 4 due to manufacturing tolerances or the like, the cover 6 is discarded because it is a defective product. Specifically, when the cover 6 is formed smaller than the outside of the housing 4, the cover 6 cannot cover the outside of the housing 4, and with manufacturing tolerances reflecting this, when the cover 6 is formed in a size larger than the outside of the housing 4 by a predetermined size, the housing 4 cannot be stably fixed due to a margin between the cover 6 and the housing 4, and thus there is a case where the cover 6 is not qualified. In contrast, according to the receptacle connector 1 of the present invention, the housing 6 includes the upper housing 61 and the lower housing 62, and the upper housing 61 and the lower housing 62 are coupled to the housing 4 in such a manner as to be closely attached to the housing 4 at the upper portion and the lower portion of the housing 4, respectively, whereby the fraction defective of the product is reduced as compared with the comparative example, and thus there is an advantage that the process cost can be reduced.

Referring to fig. 4, 7, 15 and 17, the receptacle connector 1 according to the present invention may include a sealing member 7.

The sealing member 7 serves to achieve a waterproof function. The sealing member 7 may be combined with the housing 4 at a front side of the housing 4. The sealing member 7 is closely attached to a frame (not shown) of the electronic apparatus, thereby being capable of blocking permeation of moisture or the like into the inside of the housing 4. Therefore, according to the present invention, the receptacle connector 1 can have a waterproof function between the electronic device and the electronic device, thereby contributing to the improvement of the waterproof performance of the electronic device. The sealing member 7 may be provided to the housing 4 so as to surround the outer surface 4a of the housing 4. The sealing member 7 may be formed in an elliptical ring shape as a whole. The front direction corresponds to the same direction as the separating direction (SD arrow direction). The frame may be a housing of the electronic device.

When the socket connector 1 according to the present invention comprises the sealing member 7, the housing 4 may comprise a support portion 44 for supporting the sealing member 7.

Referring to fig. 5, 7, and 14 to 17, the support portion 44 serves to support the sealing member 7. The sealing member 7 may be coupled to the support portion 44. Therefore, the receptacle connector 1 according to the present invention restricts the distance by which the seal member 7 is movable to the rear side by the support portion 44. Therefore, according to the receptacle connector 1 of the present invention, the sealing member 7 coupled to the supporting portion 44 can be prevented from being detached due to vibration, shaking, or the like occurring during the insertion process of the plug connector 200, the use process of the electronic device, or the like. Therefore, according to the receptacle connector 1 of the present invention, the state in which the sealing member 7 coupled to the support portion 44 seals between the housing 4 and the electronic device can be securely maintained. The support portion 44 and the case main body 41 can be integrally formed without a seam. The support portion 44 protrudes toward the front side of the housing 6, and thus may be located outside the housing 6. The support portion 44 may be located at the other side end of the case main body 41.

Referring to fig. 14 to 17, the support portion 44 may include a support member 441 and a support protrusion 442.

The support member 441 is used to support the sealing member 7. The sealing member 7 may be coupled to the support member 441. The housing 4 may be coupled to the cover 6 such that the support member 441 protrudes from the cover 6 to the front and is located outside the cover 6. Accordingly, the support member 441 may support the sealing member 7 such that the sealing member 7 seals between the case 4 and the electronic device outside the housing 6.

The support member 441 may be coupled to the case main body 41 in such a manner as to protrude from the case main body 41 toward the front side. The case 4 may be combined with the cover 6 in such a manner that the support member 441 is located outside the cover 6 and the case main body 41 is located inside the cover 6. The support member 441 and the case main body 41 may be integrally formed. The support member 441 may extend in a direction parallel to the second axis direction (Y-axis direction).

The support member 441 may be formed to have a length longer than that of the sealing member 7 so as to be located at the front side of the sealing member 7. For example, the support member 441 may be formed longer than the seal member 7 with respect to the second axial direction (Y-axis direction). Thus, the end of the support member 441 may be located at the front side of the sealing member 7. Therefore, according to the receptacle connector 1 of the present invention, the supporting area of the supporting member 441 is increased with the second axial direction (Y-axis direction) as a reference, so that the sealing member 7 combined with the supporting member 441 can be prevented from being detached due to vibration, shaking, or the like occurring during the insertion and separation process of the plug connector, the use process of the electronic device, or the like.

Referring to fig. 14 to 17, the support protrusion 442 serves to limit the distance that the sealing member 7 can move. The support protrusion 442 may protrude from the support member 441 in an outward direction to limit a distance that the sealing member 7 can move toward the rear side. The support protrusion 442 supports the sealing member 7 at the rear side of the sealing member 7, so that the distance that the sealing member 7 can be moved to the rear side can be limited. Therefore, according to the receptacle connector 1 of the present invention, the sealing member 7 is prevented from being detached due to vibration, shaking, or the like occurring during the insertion and separation process of the plug connector, the use process of the electronic device, or the like, so that the state in which the sealing member 7 seals between the housing 4 and the electronic device can be securely maintained.

The support protrusions 442 are combined with the support member 441. The housing 4 may be combined with the cover 6 in such a manner that the supporting protrusions 442 protrude from the cover 6 toward the front side to be located outside the cover 6.

The support protrusions 442 may be coupled to the support member 441 to protrude outward from the support member 441. The support protrusions 442 may be coupled to the support member 441 to protrude in the third axis direction (Z axis direction) with respect to the support member 441. Therefore, according to the receptacle connector 1 of the present invention, the sealing member 7 may be formed to have a sectional thickness equivalent to the height of the supporting projection 442 projecting from the supporting member 441. The support protrusions 442 may be formed on the outer surface of the support member 441 in the circumferential direction of the support member 441. The support protrusion 442 may be formed in an elliptical ring shape as a whole, but is not limited thereto, and may be formed in other shapes as long as it can be supported by the sealing member 7.

The supporting protrusions 442 may also be formed to protrude from the supporting member 441 in the outer side direction to contact with a frame of the electronic device such that the supporting protrusions 442 are sealed between the outer surface 4a of the case 4 and the frame. When an insertion hole into which the supporting protrusion 442 is inserted is formed at the frame, the size of the supporting protrusion 442 may be the same as that of the insertion hole. Therefore, the support protrusion 442 is inserted into the insertion hole to be closely attached to the frame, so that the space between the outer surface 4a of the housing 4 and the frame can be sealed. The size of the supporting protrusion 442 may be larger than that of the insertion hole. In this case, the supporting protrusions 442 may be fixed to the frame by an Interference Fit (Interference Fit), so that the sealing force between the outer surface 4a of the housing 4 and the frame may be further increased.

The support protrusion 442 may be combined with the support member 441 in such a manner as to protrude further outward from the support member 441 than the sealing member 7. That is, a length 442H of the supporting protrusion 442 protruding from the supporting member 441 is longer than a length 7H of the sealing member 7 combined with the supporting member 441, with the third axis direction (Z axis direction) as a reference. Therefore, according to the receptacle connector 1 of the present invention, the sealing member 7 can be prevented from being detached from the supporting projections 442 and moving to the rear side of the supporting projections 442 during the insertion of the plug connector. However, the present invention is not limited thereto, and the supporting protrusion 442 may be formed to protrude outward from the supporting member 441 by a length corresponding to the protruding length of the sealing member 7 outward from the supporting member 441. The supporting protrusions 442, the supporting members 441, and the case main body 41 may be integrally formed.

Referring to fig. 14 and 15, the support member 441 may be formed to have a thickness thicker than the case main body 41. That is, the support member 441 may be formed to have a length longer than that of the case main body 41 in the third axis direction (Z axis direction). In this case, the support member 441 may include: a first support member 441a, a second support member 441b, and a connecting support member 441 c.

The first support member 441a may be formed to extend from the case main body 41. The first support member 441a may be formed to extend from the case main body 41 to the front side. The first support member 441a may support the second support member 441b at an inner side of the second support member 441 b.

The second support member 441b may support the sealing member 7. The sealing member 7 may be combined with the second support member 441b and supported by the second support member 441 b. The second support member 441b may support the sealing member 7 at an outer side of the first support member 441 a.

The connection support member 441c is used to connect the first support member 441a and the second support member 441 b. The connection support member 441c may be combined with each of the first and

second support members

441a and 441b to connect the first and

second support members

441a and 441 b. The connection support member 441c may be formed along the third axis direction (Z axis direction) to connect the first support member 441a and the second support member 441 b. Therefore, the second support member 441b can support the sealing member 7 at the outer side of the first support member 441 a. The support protrusion 442 may be coupled to the second support member 441b in such a manner as to protrude in the outer direction from one end of the second support member 441b, which is not coupled to the coupling support member 441 c.

The connection support member 441c, the second support member 441b, and the first support member 441a may be integrally formed. In this case, the support member 441 may be formed by bending a plate material such that the support member 441 has the connection support member 441c, the second support member 441b, and the first support member 441 a. Therefore, the connection support member 441c may be formed such that a surface facing the front side forms a curved surface.

In addition, as described above, the case main body 41, the supporting member 441, and the supporting protrusions 442 may be integrally formed, and in this case, the case 4 may be formed by bending a plate material to form the supporting member 441, the case main body 41, and the supporting protrusions 442, and the supporting member 441 includes the connection supporting member 441c, the second supporting member 441b, and the first supporting member 441 a.

Therefore, compared with the comparative example in which the support member 441 and the support protrusion 442 are separately formed in the housing main body 41, the receptacle connector 1 according to the present invention can reduce the number of working man-hours and can form a structure for supporting the sealing member 7, and therefore, not only can the manufacturing cost be reduced, but also the productivity can be improved by shortening the manufacturing time.

Also, according to the receptacle connector 1 of the present invention, the end of the plate material 10 shown in fig. 6 is bent to form the supporting member 441 and the supporting protrusion 442, so that the size of the housing main body 41 can be prevented from being increased. In the comparative example, the sealing member 7 can be supported by increasing the thickness of the housing main body 41, so that the supporting member 441 and the housing main body 41 have steps, and therefore, compared to the comparative example, the receptacle connector 1 according to the present invention has an advantage that miniaturization can be achieved.

In the embodiment, the support member 441 and the support protrusions 442 are formed by bending the ends of a plate material, and thus, the support member 441 is formed to have a thickness thicker than the case main body 41. However, the present invention is not limited thereto.

For example, referring to fig. 16 and 17, the receptacle connector 1 according to another embodiment of the present invention may be formed such that the supporting member 441 has the same thickness as the housing main body 41. In this case, the supporting protrusion 442 may include: a first supporting protrusion 442a, a second supporting protrusion 442b, and a coupling supporting protrusion 442 c.

The first supporting protrusions 442a may be formed to extend from the housing main body 41. The first supporting protrusion 442a may be formed to protrude from the case main body 41 in the outer direction. The first supporting protrusions 442a may support the second supporting protrusions 442b at the rear side of the second supporting protrusions 442 b.

The second supporting protrusions 442b are formed in front of the first supporting protrusions 442 a. The second supporting protrusions 442b are arranged in parallel with respect to the first supporting protrusions 442a, so that the distance that the sealing member 7 can be moved to the rear side can be limited. Therefore, according to the receptacle connector 1 of the present invention, the movement of the sealing member 7 can be more stably restricted, compared to the comparative example in which the movement of the sealing member 7 is restricted only by the first supporting projection 442a or the second supporting projection 442 b.

The coupling supporting protrusion 442c is used to couple the first supporting protrusion 442a and the second supporting protrusion 442 b. The coupling supporting protrusions 442c may be combined with each of the first and second supporting

protrusions

442a and 442b to couple the first and second supporting

protrusions

442a and 442 b. The coupling supporting protrusions 442c may be formed along the second axis direction (Y axis direction) to couple the first supporting protrusions 442a and the second supporting protrusions 442 b. The coupling supporting protrusions 442c may couple the first and second supporting

protrusions

442a and 442b at outer sides of the first and second supporting

protrusions

442a and 442 b. The support member 441 may be formed at the second support protrusion 442b in such a manner as to protrude from one end of the second support protrusion 442b, which is not connected to the connection support protrusion 442c, toward the front side.

The coupling supporting protrusions 442c, the second supporting protrusions 442b, and the first supporting protrusions 442a may be integrally formed. In this case, the supporting protrusions 442 are formed by bending a sheet material such that the supporting protrusions 442 have the coupling supporting protrusions 442c, the second supporting protrusions 442b, and the first supporting protrusions 442 a. Therefore, the coupling supporting protrusion 442c may be formed such that a surface facing the outer direction side forms a curved surface.

Also, as described above, the case main body 41, the supporting member 441, and the supporting protrusions 442 may be integrally formed, in which case the case 4 forms the supporting protrusions 442, the supporting member 441, and the case main body 41 by pressing a plate material, and the supporting protrusions 442 include the coupling supporting protrusions 442c, the second supporting protrusions 442b, and the first supporting protrusions 442 a.

Therefore, compared with the comparative example in which the support protrusions 442 are formed separately in the housing main body 41, the receptacle connector 1 according to the present invention can reduce the number of working man-hours and can form a structure for supporting the sealing member 7, and therefore, not only can the manufacturing cost be reduced, but also the productivity can be improved by shortening the manufacturing time.

In addition, the receptacle connector of the present invention forms the supporting protrusion 442 by pressing a plate material, so that the size of the housing main body 41 can be prevented from being increased. In the comparative example, the sealing member 7 can be supported by increasing the thickness of the housing main body 41, so that the supporting member 441 and the housing main body 41 have steps, and therefore, compared to the comparative example, the receptacle connector 1 according to the present invention has an advantage that miniaturization can be achieved.

The present invention described above is not limited to the above-described embodiments and drawings, and it is obvious to those skilled in the art that various substitutions, modifications, and changes can be made without departing from the technical spirit of the present invention.
