Hereinafter, an embodiment of the receptacle connector according to the present invention will be described in detail with reference to the drawings.

< first embodiment >

Referring to fig. 1 to 3, a receptacle connector 1 according to the present invention is provided in various electronic apparatuses for electrical connection between a plug connector and a substrate. The substrate is disposed on the electronic device, and may be a Printed Circuit Board (PCB), for example.

The receptacle connector 1 of the present invention may include: a plurality of contactors 2 electrically connecting the plug connector and the substrate; an insulating part 3, the contactor 2 being provided to the insulating part 3; a shield portion 4 configured to shield the insulating portion 3; and a cover 5, wherein the insulating part 3 is arranged on the cover 5.

The contactor 2 is in contact with a plug connector inserted into the cover 5 in a state of being mounted on the substrate, thereby electrically connecting the plug connector and the substrate. The plug connector can be brought into contact with the contactor 2 by being inserted into an insertion groove 50 provided in the cover 5. The insulating portion 3 is for supporting the contactor 2. The insulating portion 3 may be provided to the cover 5 in such a manner that a front face 3a (shown in fig. 1) thereof is located at the insertion groove 50. The cover 5 may be formed so that the front face 3a side of the insulating portion 3 and the rear face 3b (shown in fig. 2) side of the insulating portion 3 are open. In this case, the front face 3a side of the insulating portion 3 in the cover 5 needs to be realized in an open manner to insert the plug connector, whereas the rear face 3b (shown in fig. 2) side of the insulating portion 3 in the cover 5 only needs to secure a space capable of mounting the contactor 2 to the substrate. Therefore, it is possible to generate unnecessary radiation of the signal by the rear face 3b side of the insulating portion 3 in the cover 5. In order to reduce such radiation of signals generated by the rear face 3b side of the insulating portion 3, the shield portion 4 may be combined with the cover 5 in such a manner as to shield the rear face 3b of the insulating portion 3. Thus, the receptacle connector 1 of the present invention can achieve the following operational effects.

First, the receptacle connector 1 of the present invention can reduce the radiation of signals generated during signal transmission by using the shielding part 4. Therefore, the receptacle connector 1 of the present invention can improve the signal transmission performance.

Second, the receptacle connector 1 according to the present invention can reduce the performance degradation of other devices included in the application electronic device due to the radiated signal. For example, when the receptacle connector 1 of the present invention is applied to a cellular phone, it is possible to reduce the degree of performance degradation of an antenna provided in the cellular phone due to a radiated signal. Further, the receptacle connector 1 of the present invention can reduce the degree of performance degradation of other devices provided in the application electronic device even if high-speed transmission of signals is realized. Therefore, the receptacle connector 1 of the present invention is realized to provide the application electronic device with a function of transmitting signals at a high speed, and thus can contribute to further improving the performance of the application electronic device.

The contactor 2, the insulating part 3, the shielding part 4, and the cover 5 will be described in detail below with reference to the accompanying drawings.

Referring to fig. 1 to 5, the contactor 2 is used to electrically connect the plug connector and the substrate. The contact 2 is in contact with the plug connector in a state of being mounted on the board, so that the plug connector and the board can be electrically connected. The contact 2 may be formed of a material having conductivity.

The contactor 2 may be provided to the insulating part 3. A plurality of the contacts 2 may be provided in the insulating portion 3. The contacts 2 may be provided in the insulating portion 3 so as to be spaced apart from each other in the first axial direction (X-axis direction). Specifically, one of the contacts 2 is observed as follows with reference to fig. 4 and 5 as an example.

The contactor 2 may include a contact member 21 and a mounting member 22.

The contact member 21 is for contacting the plug connector. The contact 2 may be provided in the insulating portion 3 such that the contact member 21 is supported by the insulating portion 3.

The mounting member 22 is mounted to the substrate. The mounting member 22 is mounted on the substrate to be electrically connected to the substrate. Thereby, the plug connector contacting the contact member 21 can be electrically connected with the substrate through the mounting member 22. The contactor 2 may be provided in the insulating portion 3 such that the mounting member 22 is located outside the insulating portion 3. The contactor 2 may be provided to the insulating portion 3 in such a manner that the mounting member 22 is arranged in parallel with the substrate.

The contactor 2 may comprise a connection member 23.

The connecting member 23 is used to connect the contact member 21 and the mounting member 22. The connecting member 23 is located between the contact member 21 and the mounting member 22. The connection member 23 may be coupled to the contact member 21 at one side and the mounting member 22 at the other side. The connecting member 23, the mounting member 22, and the contact member 21 may be formed in one body.

The connecting member 23 may connect the contact member 21 and the mounting member 22 such that the contact member 21 and the mounting member 22 are located at positions different from each other with reference to the first axis direction (X-axis direction). In this case, the connection member 23 may include an inclined member 231. The inclined member 231 may be configured to be inclined toward a direction inclined by a predetermined angle with reference to the second axis direction (Y-axis direction). The second axis direction (Y axis direction) is a direction perpendicular to the first axis direction (X axis direction).

Thus, the mounting members 22 can be arranged at a narrower interval than the contact members 21 with respect to the first axial direction (X-axis direction). Therefore, the receptacle connector 1 of the present invention can reduce the area occupied by the mounting members 22 in the substrate by reducing the intervals between the mounting members 22 in the case where the contacts 2 are connected to the substrate. Thus, the receptacle connector 1 of the present invention can improve the space utilization rate for the substrate. The contactor 2 may include inclined members 231 inclined at different angles according to positions of the contactor 2 arranged with reference to the first axial direction (X-axis direction). At least one of the contactors 2 may further include a connection member 23 without the inclined member 231 according to a position where the contactors 2 are arranged with reference to the first axis direction (X-axis direction).

The connecting member 23 may connect the contact member 21 and the mounting member 22 such that the contact member 21 and the mounting member 22 are located at positions different from each other with reference to the third axis direction (Z axis direction). The third axis direction (Z axis direction) is a direction perpendicular to each of the first axis direction (X axis direction) and the second axis direction (Y axis direction), and may correspond to a height direction. In this case, the connection member 23 may include a bending member 232. The bending member 232 may be formed by bending with reference to the third axis direction (Z axis direction). For example, the bending member 232 may be formed by bending ㄈ with reference to the third axis direction (Z axis direction).

Referring to fig. 1 to 6, the insulating part 3 serves to support the contactor 2. The insulating portion 3 may be provided with the contactor 2. The contactor 2 may be configured of a contactor in which the contact member 21 is positioned on the upper surface of the insulating part 3 (hereinafter, referred to as a "first contactor 2 a") and a contactor in which the contact member 21 is positioned on the lower surface of the insulating part 3 (hereinafter, referred to as a "second contactor 2 b"). The first contacts 2a may be provided on the insulating portion 3 so that the contact members 21 are spaced apart from each other in the first axial direction (X-axis direction) on the upper surface of the insulating portion 3. The second contacts 2b may be provided on the insulating portion 3 such that the contact members 21 are spaced apart from each other along the first axial direction (X-axis direction) below the insulating portion 3. Thereby, the insulating portion 3 may be configured to be located between the contact member 21 of the first contactor 2a and the contact member 21 of the second contactor 2 b. Therefore, the insulating portion 3 can insulate the contact member 21 of the first contactor 2a and the contact member 21 of the second contactor 2b from contacting each other. The first and second contacts 2a and 2b may be provided to the insulating part 3 by injection Molding (Insert Molding). The first contactors 2a may include mounting members 22 mounted to the substrates, respectively. The second contactors 2b may include mounting members 22 mounted to the substrates, respectively.

The insulating portion 3 may be provided to the cover 5 so as to be located inside the cover 5. The insulating portion 3 may be provided to the cover 5 such that the front surface 3a is positioned in the insertion groove 50. The plug connector is inserted into the cover 5 through the insertion groove 50 so as to be contactable with the contact member 21 provided to the insulating portion 3.

The insulating part 3 may include a first support member 31.

The first support member 31 is used to support the contact member 21. The first support member 31 may support the contact members 21 in such a manner that the contact members 21 are arranged spaced apart from each other along the first axial direction (X-axis direction). The first contacts 2a may be provided on the insulating portion 3 so that the contact members 21 are spaced apart from each other in the first axial direction (X-axis direction) on the upper surface of the first support member 31. The second contacts 2b may be provided on the insulating portion 3 so that the contact members 21 are spaced apart from each other along the first axial direction (X-axis direction) below the first support member 31. The front face of the first support member 31 may constitute the front face 3a of the insulating part 3. The insulating portion 3 may be provided in the cover 5 such that a front surface of the first support member 31 faces forward (FD arrow direction). The insulating portion 3 may be provided in the cover 5 such that the rear surface 311 of the first support member 31 faces rearward (in the BD arrow direction). The rear direction (BD arrow direction) is the same direction as the direction in which the plug connector moves so as to be inserted into the insertion slot. The front direction (FD arrow direction) is a direction opposite to the rear direction (BD arrow direction).

The insulating part 3 may include a second support member 32.

The second support member 32 is used to support the mounting member 22. The second support member 32 may be configured to project from the first support member 31 toward the rear (BD arrow direction) side. The second support member 32 may be configured to project from a part of the rear face 311 of the first support member 31 toward the rear (BD arrow direction) side. The first contact 2a and the second contact 2b may be provided on the insulating portion 3 such that the mounting member 22 is supported by the second support member 32. The first contact 2a and the second contact 2b may be provided in the insulating portion 3 such that the mounting members 22 are positioned at the same height with respect to the third axis direction (Z axis direction). In this case, the bending member 232 of the first contact 2a and the bending member 232 of the second contact 2b may be formed by bending at different heights from each other. The first contacts 2a and the second contacts 2b may be provided in the insulating portion 3 such that the mounting members 22 are arranged in different rows from each other with reference to the second axis direction (Y axis direction). In this case, the connection member 23 of the first contactor 2a and the connection member 23 of the second contactor 2b may be formed in different lengths from each other with reference to the second axis direction (Y axis direction). The second support member 32 and the first support member 31 may be formed in one body. The insulating portion 3 may be provided to the cover 5 such that a rear face 321 of the second support member 32 faces the rear (BD arrow direction) side.

Referring to fig. 1 to 9, the shielding part 4 is for shielding the rear surface 3b of the insulating part 3. Thereby, the shield portion 4 can reduce radiation of a signal generated through the rear face 3b side of the insulating portion 3. The rear face 3b of the insulating part 3 may include a rear face 311 of the first support member 31 and a rear face 321 of the second support member 32. The shield portion 4 can prevent the radiation of the signal from being generated through the rear surface 3b side of the insulating portion 3 by shielding at least one of the rear surface 311 of the first support member 31 and the rear surface 321 of the second support member 32. The shielding part 4 may be configured to shield the rear face 3b of the insulating part 3 in combination with the cover 5.

The shield 4 may be made of a conductive material. In this case, the shield portion 4 may be grounded (Ground). Thus, in the receptacle connector 1 of the present invention, the shielding force of the shielding portion 4 for shielding the signal from the radiation through the rear surface 3b of the insulating portion 3 is increased, and the radiation of the signal through the rear surface 3b of the insulating portion 3 can be further reduced. For example, the shield portion 4 may be formed of metal.

The shield portion 4 may be mounted on the substrate so as to be grounded. The shield 4 may also be grounded through the cover 5 in combination with the cover 5. In this case, the cover 5 may be made of a conductive material and may be mounted on the substrate so as to be grounded. For example, the cover 5 may be formed of metal. The shield 4 is coupled to the cover 5 in an electrically connected manner with the cover 5, so that grounding can be performed through the cover 5. The shield 4 and the cover 5 may be formed in one piece.

The shield 4 may include a contact face 411 (shown in fig. 9) and an opposite face 412 (shown in fig. 9).

The contact surface 411 may be configured to contact the rear surface 3b of the insulating portion 3. Thereby, the contact surface 411 can prevent radiation of a signal from being generated through the rear surface 3b side of the insulating portion 3.

The opposite surface 412 may be formed to be connected with the contact surface 411. The opposite face 412 may be configured to face the contactor 2.

The opposing surface 412 may be formed in an inclined manner. In this case, an Included Angle (Included Angle)412a between the opposite surface 412 and the contact surface 411 may form an obtuse Angle. That is, the facing surface 412 may be formed to be inclined toward the rear (BD arrow direction). Thus, the receptacle connector 1 of the present invention can extend the insulation distance D1 (shown in fig. 9) by which the shield part 4 is spaced from the bent member 232 even when the shield part 4 is disposed close to the bent member 232 of the contact 2 provided in the insulating part 3. In this case, the bending member 232 of the second contact 2b may be disposed close to the shielding member 4. Therefore, the receptacle connector 1 of the present invention can reduce not only the radiation of signals but also the risk of short circuit between the bent member 232 and the shield portion 4 by the shield portion 4, thereby realizing a damage prevention structure for the bent member 232 and the shield portion 4. The shield portion 4 may be implemented such that a portion of the facing surface 412 and the bent member 232 spaced apart from each other by the shortest distance is 0.3mm or more.

The shield portion 4 may include a first shield member 41.

The first shielding member 41 is for shielding the rear surface 311 of the first support member 31. Thereby, the first shield member 41 can reduce radiation of a signal generated through the rear surface 311 side of the first support member 31. The first shielding member 41 may be configured to shield the rear surface 311 of the first support member 31 in conjunction with the cover 5. The first shielding member 41 may be configured to shield the remaining portion except for the portion where the second support member 32 protrudes, at the rear face 311 of the first support member 31.

In the case where the insulating portion 3 is provided with the first and second contacts 2a and 2b, the first shielding member 41 may be configured to shield the rear face 3b of the insulating portion 3 at a position spaced downward from the mounting member 22 of the second contact 2 b. In this case, the first shielding member 41 may be configured to contact the rear face 3b of the insulating part 3 outside the insulating part 3.

The first shielding member 41 may include the contact face 411 and the opposite face 412.

The contact surface 411 may be configured to contact the rear surface 311 of the first support member 31. Thereby, the contact face 411 can prevent radiation of a signal from being generated through the rear face 311 side of the first support member 31. The contact surface 411 may correspond to a front surface facing the front (FD arrow direction) side from the first shielding member 41.

The opposite surface 412 may be formed to be connected with the contact surface 411. The opposite face 412 may be configured to face the contactor 2. In the case where the first shielding member 41 is configured to be positioned on the lower side of the second supporting member 32, the opposed face 412 may correspond to the upper face of the first shielding member 41.

The opposing surface 412 may be formed in an inclined manner. In this case, the included angle 412a between the facing surface 412 and the contact surface 411 may form an obtuse angle. That is, the facing surface 412 may be formed to be inclined toward the rear (BD arrow direction). Thus, the receptacle connector 1 of the present invention can extend the insulation distance D1 by which the first shield member 41 is spaced from the bent member 232 even when the first shield member 41 is disposed close to the bent member 232 of the contact 2 provided in the insulating portion 3. In this case, the bending member 232 of the second contact 2b may be disposed close to the first shielding member 41. Therefore, the receptacle connector 1 of the present invention can reduce the risk of short circuit between the bent member 232 and the first shielding member 41 by using the first shielding member 41, as well as reducing the radiation of signals, thereby realizing a damage prevention structure for the bent member 232 and the first shielding member 41. The first shielding member 41 may be implemented such that a portion spaced apart by a shortest distance between the facing surface 412 and the bent member 232 is 0.3mm or more.

The first shielding member 41 may be formed to a length shorter than the rear surface 311 of the first support member 31 with reference to the third axis direction (Z axis direction). Thus, the receptacle connector 1 of the present invention can extend the insulation distance D2 (shown in fig. 9) by which the first shield member 41 is spaced from the mounting member 22 of the contact 2 provided in the insulating portion 3 with reference to the third axial direction (Z-axis direction). In this case, the insulation distance D2 by which the facing surface 412 of the first shield member 41 is spaced from the mounting member 22 of the second contact 2b can be extended. The mounting member 22 of the second contact 2b may be supported by the second support member 32 so as to project from the rear surface 311 of the first support member 31 to the rear (BD arrow direction) side. Therefore, the receptacle connector 1 of the present invention can reduce not only the radiation of signals but also the risk of short circuit between the mounting member 22 and the first shielding member 41 by using the first shielding member 41, thereby realizing a damage prevention structure for the mounting member 22 and the first shielding member 41. The first shielding member 41 may be implemented such that a portion spaced apart by a shortest distance between the facing surface 412 and the mounting member 22 is 0.5mm or more.

Referring to fig. 1 to 11, the shield part 4 may include a second shield member 42.

The second shielding member 42 is for shielding the rear face 321 of the second support member 32. Thereby, the second shielding member 42 can reduce radiation of a signal generated through the rear face 321 side of the second supporting member 32. The second shielding member 42 may be configured to shield the rear face 321 of the second support member 32 in conjunction with the cover 5.

The second shielding member 42 may be formed to have a length longer than the rear face 321 of the second support member 32 with reference to the third axis direction (Z axis direction). In this case, the second shielding member 42 may be configured to shield the entirety of the rear face 321 of the second support member 32. Accordingly, the receptacle connector 1 according to the present invention can increase the shielding force for shielding the signal from being radiated toward the rear surface 321 side of the second support member 32 by the second shielding member 42, and can further reduce the signal from being radiated toward the rear surface 321 side of the second support member 32.

The second shielding member 42 may be configured to shield the rear face 321 of the second support member 32 at a position spaced apart from the mounting member 22 toward the rear (BD arrow direction). Thereby, the receptacle connector 1 of the present invention can elongate the insulation distance D3 (shown in fig. 11) by which the second shield member 42 is spaced from the mounting member 22. In this case, an insulation distance D3 by which the second shielding member 42 is spaced from the mounting member 22 of the first contactor 2a can be elongated. The mounting member 22 of the first contact 2a can be supported by the second support member 32 so as to project from the rear surface 321 of the second support member 32 to the rear (BD arrow direction) side. Therefore, the receptacle connector 1 of the present invention can reduce not only the radiation of signals but also the risk of short circuit between the mounting member 22 and the second shielding member 42 by using the second shielding member 42, thereby realizing a damage prevention structure for the mounting member 22 and the second shielding member 42. The receptacle connector 1 according to the present invention may be realized such that a portion of the second shield member 42 and the mounting member 22 spaced apart from each other by the shortest distance is 0.5mm or more. The second shield member 42 is disposed so as to be spaced from the rear face 321 of the second support member 32 with reference to the second axial direction (Y-axis direction), and thus can be disposed so as to be spaced from the insulating member 22.

The receptacle connector 1 of the present invention can be brought into contact not only when the plug connector is in the first state but also when the plug connector is in the second state reversed from the first state. That is, the receptacle connector 1 of the present invention can make contact regardless of the directionality of the plug connector. Accordingly, the receptacle connector 1 of the present invention can connect the plug connector to the board in a state where the plug connector is oriented in either direction of the first state and the second state, and can be easily used even in a narrow space, a dark space, or the like.

For this reason, the receptacle connector 1 of the present invention can be realized by configuring the first contacts 2a and the second contacts 2b as follows.

Referring to fig. 9 and 14, the shield part 4 may include a first partition groove 43 (shown in fig. 14).

The first partition groove 43 may be configured to be positioned at a lower side of the power source contactor 22b in the contactor 2. The first partition groove 43 may be formed to penetrate the first shielding member 41.

The power supply contactor 22b may belong to the second contactor 2 b. Thus, the receptacle connector 1 of the present invention can be further extended by an insulation distance D2 (shown in fig. 9) that the first shield member 41 is spaced from the mounting member 22 of the power contact 22b with reference to the third axis direction (Z axis direction). Also, the receptacle connector 1 of the present invention may further extend the insulation distance D1 (shown in fig. 9) by which the first shielding member 41 is spaced from the bent member 232 of the power contact 22 b. Therefore, in the receptacle connector 1 of the present invention, the first shielding member 41 not only reduces the radiation of the signal, but also further reduces the risk of short circuit between the power contact 22b and the first shielding member 41, thereby realizing a more stable damage prevention structure for the power contact 22b and the first shielding member 41. The first shielding member 41 may be configured such that the first partition groove 43 is located at a lower side of the mounting member 22 that the power contactor 22b has.

The power supply contactor 22a may belong to the first contactor 2 a. Thus, the receptacle connector 1 of the present invention can further elongate the insulation distance D3 (shown in fig. 11) by which the second shield member 42 is spaced from the mounting member 22 of the power contact 22 a. Therefore, in the receptacle connector 1 of the present invention, the second shielding member 42 not only reduces the radiation of the signal, but also further reduces the risk of short circuit between the power contact 22a and the second shielding member 42, thereby realizing a more stable damage prevention structure for the power contact 22a and the second shielding member 42. The second shielding member 42 may be configured such that the second separation groove 44 is located behind the mounting member 22 (BD arrow direction) of the power contact 22 a.

The shield portion 4 may include a plurality of the second separation grooves 44.

The second shielding member 42 may be configured such that the second partition grooves 44, 44 'are located behind (BD arrow direction) the mounting members 22 that the power contacts 22a, 22 a' have, respectively.

Referring to fig. 1, 2, 7, 15 and 16, the cover 5 is configured to receive the insulating portion 3. The insulating portion 3 is provided to the cover 5 so as to be located inside the cover 5, and is protected by the cover 5. The cover 5 may include the insertion slot 50 (shown in fig. 1). The plug connector can contact the contactor 2 located inside the cover 5 by being inserted into the insertion groove 50. The cover 5 may be formed so that its front (FD arrow direction) side and rear (BD arrow direction) side are open. The open front (FD arrow direction) side of the cover 5 can communicate with the insertion groove 50. The open rear (BD arrow direction) side of the cover 5 can be shielded by the shield 4. The shield 4 may be combined with the cover 5.

The cover 5 may be made of a conductive material and may be attached to the substrate so as to be grounded. In this case, the shield 4 may be coupled to the cover 5 in such a manner that the cover 5 is grounded. Thereby, the shielding portion 4 can increase a shielding force for shielding radiation of a signal. The shield portion 4 may be mounted on the substrate in such a manner that the substrate is directly grounded.

The cover 5 may comprise a lower cover 51.

The lower cover 51 is configured to be positioned at a lower side of the insulating part 3. The lower cover 51 may be configured to shield a portion of both side surfaces of the insulating part 3 while shielding the lower surface of the insulating part 3. The first shielding member 41 may be coupled to the lower cover 51. The first shielding member 41 may be combined with the lower cover 51 in such a manner as to shield the rear surface 311 of the first support member 31. Thereby, the first shield member 41 can reduce the radiation of the signal to the rear surface 311 side of the first support member 31.

The lower cover 51 and the first shielding member 41 may be formed in one body. In this case, the first shielding member 41 may be configured to be bent (Bending) with respect to the lower cover 51 to shield the rear face 311 of the first support member 31. Thus, the receptacle connector 1 of the present invention can improve the ease with which the first shielding member 41 shields the rear surface 311 of the first supporting member 31 in a state of being grounded by the lower cover 51.

The lower cover 51 may include a lower mounting member 511.

The lower mounting member 511 is for mounting to the substrate. The receptacle connector 1 of the present invention can be fixed to the substrate by the mounting force of the lower mounting member 511 to the substrate. The lower mounting member 511 may be inserted into a mounting groove (not shown) formed in the substrate. The lower mounting member 511 may be inserted into the mounting groove and mounted on the substrate by fixing it to the substrate with Solder Paste (not shown). The lower mounting member 511 may be configured to face a direction perpendicular to the mounting surface of the substrate. For example, the lower mounting member 511 may be disposed parallel to the third axis direction (Z axis direction).

The lower cover 51 may include a plurality of the lower mounting members 511. In this case, the lower mounting members 511 may be configured to be located at positions spaced apart from each other with reference to the first axial direction (X-axis direction). The insulating portion 3 may be located between the lower mounting members 511 with reference to the first axial direction (X-axis direction).

The lower cover 51 may include a lower connection member 512.

The lower connection member 512 is used to be combined with the lower mounting member 511. The lower connection member 512 may be configured to face a direction parallel to the mounting surface of the substrate. For example, the lower connection member 512 may be configured to be parallel to the first axis direction (X-axis direction). The lower connecting member 512 may be positioned between the insulating part 3 and the lower mounting member 511 with reference to the first axial direction (X-axis direction). The lower connecting member 512 may be configured to protrude outward of the insulating portion 3 with reference to the first axial direction (X-axis direction). Thus, the lower mounting member 511 can be inserted into the mounting groove at a position spaced apart from the insulating portion 3 with respect to the first axial direction (X-axis direction) and mounted on the substrate.

The lower cover 51 may include a plurality of the lower connection members 512. In this case, the lower cover 51 may include the same number of lower connection members 512 as the lower mounting members 511. The lower connection members 512 may be respectively combined with the respective lower mounting members 511.

The cover 5 may include an upper cover 52.

The upper cover 52 is disposed on the upper side of the insulating portion 3. The upper cover 52 may be configured to cover an upper surface of the insulating part 3 and to cover a part of both side surfaces of the insulating part 3. Both side surfaces of the insulating part 3 may be entirely covered by the upper cover 52 and the lower cover 51. The second shielding member 42 may be coupled to the upper cover 52. The second shielding member 42 may be combined with the upper cover 52 in such a manner as to shield the rear face 321 of the second support member 32. Thereby, the second shield member 42 can reduce the radiation of the signal to the rear face 321 side of the second support member 32.

The upper cover 52 and the second shielding member 42 may be formed in one body. In this case, the second shielding member 42 may be configured to be bent with respect to the upper cover 52 to shield the rear face 321 of the second support member 32. Thus, the receptacle connector 1 of the present invention can improve the ease with which the second shield member 42 shields the rear face 321 of the second support member 32 in a state of being grounded by the upper cover 52.

The upper cover 52 may include an upper mounting member 521.

The upper mounting member 521 is for mounting to the substrate. The receptacle connector 1 of the present invention can be fixed to the board by the mounting force of the upper mounting member 521 to the board. The upper mounting member 521 may be inserted into a mounting groove formed in the substrate. The upper mounting member 521 may be inserted into the mounting groove and mounted in such a manner that the solder paste applied to the substrate is fixed to the substrate. The upper mounting member 521 may be configured to face a direction perpendicular to the mounting surface of the substrate. For example, the upper mounting member 521 may be disposed parallel to the third axis direction (Z axis direction).

The upper mounting member 521 and the lower mounting member 511 may be arranged side by side to be inserted into one mounting groove formed in the substrate. Thus, in the receptacle connector 1 of the present invention, the upper mounting member 521 and the lower mounting member 511 can increase the mounting area on the substrate, thereby further increasing the fixing force to the substrate. The upper mounting member 521 and the lower mounting member 511 may be arranged side by side with reference to the first axial direction (X-axis direction).

The upper cover 52 may be provided on the insulating portion 3 such that the upper mounting member 521 is arranged in parallel with the lower mounting member 511 and the upper mounting member 521 is located at a position spaced apart from the lower mounting member 511. That is, the upper mounting member 521 and the lower mounting member 511 may be configured to be arranged side by side to be inserted into a mounting groove formed on the substrate, and to be arranged to be spaced apart from each other. Thus, the receiving groove 511a (shown in fig. 15) may be located between the upper mounting member 521 and the lower mounting member 511. The cover 5 may be mounted on the substrate in such a manner as to receive solder paste in the receiving groove 511 a. Therefore, the socket connector 1 of the present invention can increase the amount of solder paste for fixing the upper mounting member 521 and the lower mounting member 511 to the board through the receiving groove 511a, and can further increase the fixing force to the board.

The upper cover 52 may include a plurality of the upper mounting members 521. In this case, the upper mounting members 521 may be disposed at positions spaced apart from each other with reference to the first axial direction (X-axis direction). The lower mounting members 511 may be positioned between the upper mounting members 521 with reference to the first axial direction (X-axis direction).

The upper cover 52 may include an upper connecting member 522.

The upper connecting member 522 is used to be combined with the upper mounting member 521. The upper connection member 522 may be configured to face a direction parallel to the mounting surface of the substrate. For example, the upper connection member 522 may be configured to be parallel to the first axis direction (X-axis direction). The upper connecting member 522 may be positioned between the insulating part 3 and the upper mounting member 521 with reference to the first axial direction (X-axis direction). The upper connecting member 522 may be configured to protrude outward of the insulating portion 3 with reference to the first axial direction (X-axis direction). Thus, the upper mounting member 521 can be inserted into the mounting groove and mounted on the substrate at a position spaced apart from the insulating portion 3 with reference to the first axial direction (X-axis direction).

The upper cover 52 may be configured such that the upper connection member 522 is located at an upper side of the lower connection member 512. Thus, the upper connection member 522 may press the lower connection member 512 by an installation force of the upper installation member 521 to the substrate. Therefore, the receptacle connector 1 of the present invention can more firmly fix the lower cover 51 to the substrate by the mounting force of the upper mounting member 521 to the substrate.

The upper cover 52 may include a plurality of the upper connection members 522. In this case, the upper cover 52 may include the same number of upper connection members 522 as the upper mounting members 521. The upper connecting members 522 may be respectively combined with the respective upper mounting members 521.

Referring to fig. 1, 2, 16-18, the cover 5 may include an inner cover 53.

The inner cover 53 is configured to be positioned between the upper cover 52 and the insulating part 3. The inner cover 53 may be configured to be positioned between the lower cover 51 and the insulating part 3. That is, the inner cover 53 may be located inside the lower cover 51 and the upper cover 52. The insulating part 3 may be located inside the inner cover 53. The inner cover 53 may be configured to shield the upper surface, the lower surface, and both side surfaces of the insulating part 3. Accordingly, in the receptacle connector 1 of the present invention, the upper surface, the lower surface, and both side surfaces of the insulating portion 3 are shielded by the double structure by the inner cover 53, the lower cover 51, and the upper cover 52, and thus, a shielding force for shielding a signal from being radiated through the upper surface, the lower surface, and both side surfaces of the insulating portion 3 can be increased. Therefore, the receptacle connector 1 of the present invention can significantly reduce the radiation of signals through the upper surface, the lower surface, and both side surfaces of the insulating portion 3.

The lower cover 51 may be disposed on the inner cover 53. The lower cover 51 may be positioned at the lower side of the inner cover 53 and fixed to the inner cover 53 by welding. The upper cover 52 may be disposed on the inner cover 53. The upper cover 52 may be positioned at an upper side of the inner cover 53 and fixed to the inner cover 53 by welding. Therefore, the receptacle connector 1 of the present invention can be realized as a strong structure by increasing the strength of the cover 5.

The inner cover 53 may be formed to be open at its front (FD arrow direction) side and rear (BD arrow direction) side. The open front side (FD arrow direction) of the inner cover 53 can communicate with the insertion groove 50. The open rear side (BD arrow direction) of the inner cover 53 can be shielded by the shield 4.

The inner cover 53 may include an inner mounting member 531.

The inner mounting member 531 is for mounting to the substrate. The receptacle connector 1 of the present invention can be fixed to the substrate by the mounting force of the internal mounting member 531 to the substrate. The internal mounting member 531 may be inserted into a mounting groove formed on the substrate. The internal mounting member 531 may be inserted into the mounting groove and mounted so as to be fixed to the substrate by solder paste applied to the substrate. The inner mounting member 531 may be configured to face a direction perpendicular to the mounting surface of the substrate. For example, the inner mounting member 531 may be arranged in parallel with the third axis direction (Z axis direction).

The inner mounting member 531 and the upper mounting member 521 may be arranged side by side to be inserted into one mounting groove formed on the substrate. Thus, the receptacle connector 1 according to the present invention can further increase the fixing force to the substrate by increasing the mounting area on the substrate by using the inner mounting member 531 and the upper mounting member 521. The inner attachment member 531 and the upper attachment member 521 may be arranged side by side with reference to the first axis direction (X axis direction).

The inner cover 53 may be provided to the insulating portion 3 such that the inner mounting member 531 is arranged in parallel with the upper mounting member 521 and the inner mounting member 531 is located at a position spaced apart from the upper mounting member 521. That is, the inner mounting member 531 and the upper mounting member 521 may be arranged side by side to be inserted into a mounting groove formed on the substrate and arranged to be spaced apart from each other. Thus, a receiving groove 531a (shown in fig. 18) may be located between the inner mounting member 531 and the upper mounting member 521. The cover 5 may be mounted on the substrate in such a manner as to receive solder paste in the receiving groove 531 a. Therefore, the socket connector 1 of the present invention can increase the amount of solder paste for fixing the internal mounting member 531 and the upper mounting member 521 to the board by the receiving groove 531a, and can further increase the fixing force to the board.

The inner cover 53 may include a plurality of the inner mounting members 531. In this case, the inner mounting members 531 may be arranged at positions spaced apart from each other with reference to the first axis direction (X-axis direction). The inner mounting members 531 may be disposed to be spaced apart from each other between the upper mounting members 521 with reference to the first axial direction (X-axis direction).

The inner cover 53 may include an inner connecting member 532.

The inner connecting member 532 is used to be combined with the inner mounting member 531. The internal connection member 532 may be configured to face a direction parallel to the mounting surface of the substrate. For example, the inner connecting member 532 may be arranged parallel to the first axis direction (X-axis direction). The inner connecting member 532 may be positioned between the insulating part 3 and the inner mounting member 531 with reference to the first axial direction (X-axis direction). The inner connecting member 532 may be configured to protrude outward of the insulating portion 3 with reference to the first axial direction (X-axis direction). Thus, the inner attachment member 531 can be inserted into the attachment groove and attached to the substrate at a position spaced apart from the insulating portion 3 with reference to the first axial direction (X-axis direction).

The inner cover 53 may be configured such that the inner connecting member 532 is located at the lower side of the upper connecting member 522. In this case, the upper cover 52 may be configured such that the upper connection member 522 is located at an upper side of the inner connection member 532. Thus, the upper connection member 522 may press the inner connection member 532 by an installation force of the upper installation member 521 to the substrate. Therefore, the receptacle connector 1 of the present invention can more firmly fix the inner cover 53 to the substrate by the mounting force of the upper mounting member 521 to the substrate.

The inner cover 53 may include a plurality of the inner coupling members 532. In this case, the inner cover 53 may include the same number of inner connecting members 532 as the inner mounting members 531. The inner connecting members 532 may be respectively combined with the inner mounting members 531.

The inner cover 53 may include an auxiliary mounting member 533.

The auxiliary mounting member 533 is configured to be mounted to the substrate. The receptacle connector 1 of the present invention can be fixed to the substrate by the mounting force of the auxiliary mounting member 533 and the internal mounting member 531 to the substrate. Thus, the receptacle connector 1 of the present invention can be more firmly fixed to the substrate by the auxiliary mounting member 533 and the internal mounting member 531. The auxiliary mounting member 533 can be inserted into a mounting groove formed on the substrate. The auxiliary mounting member 533 may be inserted into the mounting groove and mounted in such a manner as to be fixed to the substrate by solder paste applied to the substrate. The auxiliary mounting member 533 may be configured to face a direction perpendicular to the mounting surface of the substrate. For example, the auxiliary mounting member 533 may be arranged in parallel with the third axis direction (Z axis direction).

The auxiliary mounting member 533 may be configured to be located at a position spaced apart from the inner mounting member 531 with reference to the second axis direction (Y-axis direction). Thereby, the auxiliary mounting member 533 and the internal mounting member 531 can be mounted to different portions of the substrate by being inserted into different mounting grooves.

The inner cover 53 may include a plurality of the auxiliary mounting members 533. In this case, the auxiliary mounting members 533 may be configured to be located at positions spaced apart from each other with reference to the first axis direction (X-axis direction). The insulating portion 3 may be located between the auxiliary mounting members 533 with reference to the first axis direction (X-axis direction). The auxiliary mounting members 533 may be disposed to be located at both sides of the second support member 32 with reference to the first axis direction (X-axis direction). In this case, the inner mounting member 531 may be disposed at a position spaced forward (FD arrow direction) from the auxiliary mounting member 533 with reference to the second axis direction (Y axis direction).

The upper cover 52 may include an upper mounting member 521 disposed to be aligned with the lower mounting member 511 and an entire upper mounting member 521 disposed to be aligned with the inner mounting member 531. For example, as shown in fig. 16, in the case where two lower mounting members 511 and two inner mounting members 531 are provided, the upper cover 52 may include four upper mounting members 521.

Referring to fig. 3, 19 and 20, the cover 5 may include a first closure member 54.

The first closing member 54 is used to close the gap between the cover 5 and the shield 4. The first closing member 54 may be configured to close a gap between the lower cover 51 and the first shielding member 41. A gap between the lower cover 51 and the first shielding member 41 may be formed at the remaining portion except for the portion where the first shielding member 41 is combined with the lower cover 51. For example, in the case where the first shielding member 41 is implemented in a bent manner with respect to the lower cover 51, a slit may be formed at a portion other than a portion where the first shielding member 41 and the lower cover 51 are connected. The first closing member 54 can block the gap between the lower cover 51 and the first shielding member 41 to shield the signal from radiation through the gap between the lower cover 51 and the first shielding member 41. Therefore, the receptacle connector 1 of the present invention can increase the shielding force for shielding the signal from radiation through the rear surface 3b side of the insulating portion 3 by using the first shielding member 41 and the first closing member 54, and can further reduce the signal from radiation through the rear surface 3b side of the insulating portion 3.

The first closing member 54 may close a gap between the lower cover 51 and the first shielding member 41 by being combined with the lower cover 51 and the first shielding member 41, respectively. The first closing member 54 may be implemented by performing Laser Welding (Laser Welding) on a gap between the lower cover 51 and the first shielding member 41.

The cover 5 may comprise a plurality of said first closure members 54. The first closing member 54 may be combined with the cover 5 and the shield 4, respectively, at positions spaced apart from each other. The first closing member 54 may be combined with the lower cover 51 and the first shielding member 41, respectively, at positions spaced apart from each other. Thus, the socket connector 1 of the present invention can partially close the gap between the lower cover 51 and the first shield member 41 by the first closing member 54, and reduce the length of each gap. Therefore, the receptacle connector 1 of the present invention can reduce the radiation of the signal through the rear surface 3b side of the insulating portion 3 by using the first closing member 54. Further, the receptacle connector 1 of the present invention can reduce the manufacturing cost by reducing the material cost and can improve the ease of the manufacturing process, as compared with the case where all the gaps between the lower cover 51 and the first shield member 41 are closed. Although the cover 5 is shown in fig. 19 to include four first closing members 54, the present invention is not limited thereto, and the cover 5 may include two, three, or five or more first closing members 54. Although not shown, the first closing member 54 may close all gaps between the lower cover 51 and the first shielding member 41. In this case, the first closing members 54 may be formed in such a manner as to overlap each other with a portion thereof.

Wherein, as shown in fig. 19, a portion of the first closing member 54 may be located at a position hidden by the auxiliary mounting member 533. In this case, the first shielding member 41 may be connected with the lower cover 51 with the first axial direction (X-axis direction) as a reference so that a middle portion thereof is integrally formed with the lower cover 51 to be bent while both side portions thereof are separately formed with respect to the lower cover 51. Thus, a part of the gap between the both side portions of the first shielding member 41 and the lower cover 51 can be blocked by the auxiliary mounting member 533 with reference to the first axial direction (X-axis direction). Therefore, in a portion of the gap between the first shielding member 41 and the lower cover 51, which is blocked by the auxiliary mounting member 533, the first blocking member 54 is not easily formed due to interference with the auxiliary mounting member 533.

To solve this problem, as shown in fig. 20, the shield portion 4 may include a plurality of the first shield members 41. In this case, the first closing member 54 may be coupled to the first shielding members 41 in such a manner as to close the gap between the first shielding members 41 at a position spaced apart from the auxiliary mounting member 533 with reference to the first axial direction (X-axis direction). Therefore, in the receptacle connector 1 of the present invention, when the work of forming the first closing member 54 is performed, the degree of interference of the auxiliary attaching member 533 can be reduced, and the ease of the work of forming the first closing member 54 can be improved. In this case, it may be realized that a portion of the first shielding member 41 formed integrally with respect to the lower cover 51 is located at a portion shielded by the auxiliary mounting member 533. Thereby, the portion shielded by the auxiliary mounting member 533 can be realized such that no gap is formed even without the first closing member 54.

Referring to fig. 3 and 19, the cover 5 may include a second closing member 55.

The second closing member 55 is used to close the gap between the cover 5 and the shield 4. The second closing member 55 may be configured to block a gap between the upper cover 52 and the second shielding member 42. A gap between the upper cover 52 and the second shielding member 42 may be formed at the remaining portion except for the portion where the second shielding member 42 is combined with the upper cover 52. For example, in the case where the second shielding member 42 is bent with respect to the upper cover 52, a slit may be formed in the remaining portion except for the portion where the second shielding member 42 and the upper cover 52 are connected. The second closing member 55 can block the gap between the upper cover 52 and the second shielding member 42 to shield the signal from radiation through the gap between the upper cover 52 and the second shielding member 42. Therefore, the receptacle connector 1 of the present invention can increase the shielding force for shielding the signal from radiation through the rear face 3b side of the insulating portion 3 by using the second shielding member 42 and the second closing member 55, and further reduce the signal from radiation through the rear face 3b side of the insulating portion 3.

The second closing member 55 may close a gap between the upper cover 52 and the second shielding member 42 by being combined with the upper cover 52 and the second shielding member 42, respectively. The second closing member 55 may be implemented by performing laser welding to a gap between the upper cover 52 and the second shielding member 42.

The cover 5 may comprise a plurality of said second closure members 55. The second closing member 55 may be combined with the cover 5 and the shield 4, respectively, at positions spaced apart from each other. The second closing member 55 may be combined with the upper cover 52 and the second shielding member 42, respectively, at positions spaced apart from each other. Thus, the socket connector 1 of the present invention can partially close the gap between the upper cover 52 and the second shield member 42 by the second closing member 55, and reduce the length of each gap. Therefore, the receptacle connector 1 of the present invention can reduce the radiation of the signal through the rear face 3b side of the insulating portion 3 by using the second closing member 55. Further, the receptacle connector 1 of the present invention can reduce the manufacturing cost by reducing the material cost and can improve the ease of the manufacturing process, as compared with the case where all the gaps between the upper cover 52 and the second shield member 42 are closed. Although fig. 19 shows that the cover 5 includes four second closing members 55, the present invention is not limited thereto, and the cover 5 may include two, three, or five or more second closing members 55. Although not shown, the second closing member 55 may close all gaps between the upper cover 52 and the second shielding member 42. In this case, the second closing members 55 may be formed to overlap with each other at a portion thereof.

The second closing member 55 may close a gap between both side portions of the second shielding member 42 and the upper cover 52 in a case where the second shielding member 42 is connected to the upper cover 52 such that a middle portion thereof is integrally bent with the upper cover 52 and both side portions thereof are formed separately from the upper cover 52 with reference to the first axial direction (X-axis direction).

Referring to fig. 2, 21 and 22, in the receptacle connector 1 according to the modified embodiment of the present invention, the insulating portion 3 may include an intermediate plate 33.

The intermediate plate 33 may be provided to the first support member 31. The intermediate plate 33 may be provided to the first support member 31 so as to be positioned between the contact member 21 of the first contactor 2a and the contact member 21 of the second contactor 2 b. The intermediate plate 33 may be provided to be located inside the first support member 31. The intermediate plate 33 may be provided over the first support member 31 and the second support member 32. The intermediate plate 33 is grounded.

An insulation hole 331 may be formed on the middle plate 33. The insulation hole 331 may be formed to penetrate the middle plate 33. The insulation hole 331 may be configured to be located between the contact member 21 of the first power contact 22a and the contact member 21 of the second power contact 22 b. Thereby, the insulation hole 331 may elongate insulation distances S1, S2 that the first power contact 22a and the second power contact 22b are spaced apart from the middle plate 33, respectively. Therefore, in the receptacle connector 1 according to the modified embodiment of the present invention, the insulating hole 331 reduces the risk of short-circuiting between the intermediate plate 33 and the first and second power supply contacts 22a and 22b, and the intermediate plate 33 and the first and second power supply contacts 22a and 22b can be prevented from being damaged.

In the case where a plurality of first power supply contacts 22a and 22a 'and a plurality of second power supply contacts 22b and 22 b' are provided as shown in fig. 12 and 13, the insulation hole 331 may be disposed between the first power supply contacts 22a and 22a 'and the second power supply contacts 22b and 22 b', as shown in fig. 21 and 22. In this case, the insulation hole 331 may be configured to be located between the first contact member 21 of the first power source contactor 22a, 22a 'and the second contact member 31 of the second power source contactor 22b, 22 b'. Thereby, the insulation hole 331 may extend all of the insulation distance S1 that the first power contacts 22a, 22a 'are spaced from the middle plate 33 and the insulation distance S2 that the second power contacts 22b, 22 b' are spaced from the middle plate 33. Therefore, in the receptacle connector 1 according to the modified embodiment of the present invention, the insulating hole 331 reduces the risk of short-circuiting between the intermediate plate 33 and the first and second power supply contacts 22a and 22a 'and 22 b' and realizes a damage prevention structure for the intermediate plate 33 and the first and second power supply contacts 22a and 22a 'and 22 b' respectively.

The insulation hole 331 may be formed by penetrating a portion of the middle plate 33 between the first power supply contacts 22a and 22a 'and the second power supply contacts 22b and 22 b'. The insulation hole 331 may be implemented by the intermediate plate 33 as two or more grounding bodies 332, 332 'and the grounding bodies 332, 332' are configured to be spaced apart from each other with reference to the first axis direction (X-axis direction).

In this case, as shown in fig. 21, the ground body 332 configured to be positioned at one side of the insulation hole 331 may be configured to be positioned between the contact member 21 of the first transmission contactor 25a and the contact member 21 of the second transmission contactor 25 b. Thus, the grounding body 332 may be configured to shield between the contact member 21 of the first transmission contactor 25a and the contact member 21 of the second transmission contactor 25b with reference to the third axis direction (Z axis direction). Therefore, the receptacle connector 1 of the modified embodiment of the present invention can improve the signal transmission performance using the first transmission contactor 25a and the second transmission contactor 25 b.

The ground body 332 may include a ground plane 332a facing the insulation hole 331. The ground body 332 may be configured such that the ground plane 332a is located between the contact member 21 of the first transmission contactor 25a and the contact member 21 of the first power contactor 22 a. That is, the grounding body 332 may be configured to protrude toward the insulating hole 331 with reference to the contact member 21 of the first contact 25 a. Thereby, the grounding body 332 may be configured to increase an area between the contact member 21 shielding the first transmission contactor 25a and the contact member 21 shielding the second transmission contactor 25b with reference to the third axis direction (Z axis direction). Therefore, the receptacle connector 1 of the modified embodiment of the present invention can further improve the signal transmission performance using the first transmission contactor 25a and the second transmission contactor 25 b.

Although not shown, the one surface of the contact member 21 of the first transmission contact 25a and the ground surface 332a may be located on the same line parallel to the third axis direction (Z axis direction). The contact member 21 of the first transmission contact 25a has a face facing the contact member 21 of the first power source contact 22 a.

As shown in fig. 22, the ground body 332 ' configured to be positioned at the other side of the insulation hole 331 may be configured to be positioned between the contact member 21 of the first transmission contactor 25a ' and the contact member 21 of the second transmission contactor 25b '. Thus, the grounding body 332 ' may be configured to shield between the contact member 21 of the first transmission contactor 25a ' and the contact member 21 of the second transmission contactor 25b ' with reference to the third axis direction (Z axis direction). Accordingly, the receptacle connector 1 of the modified embodiment of the present invention can improve the signal transmission performance using the first transmission contacts 25a 'and the second transmission contacts 25 b'.

The ground body 332 'may include a ground plane 332 a' facing the insulation hole 331. The grounding body 332 'may be configured such that the ground plane 332 a' is located between the contact member 21 of the first transmission contactor 25a 'and the contact member 21 of the first power contactor 22 a'. That is, the ground body 332 'may be configured to protrude toward the insulation hole 331 side with reference to the contact member 21 of the first contact 25 a'. Thereby, the grounding body 332 ' may be configured to increase an area between the contact member 21 shielding the first transmission contactor 25a ' and the contact member 21 shielding the second transmission contactor 25b ' with reference to the third axis direction (Z axis direction). Therefore, the receptacle connector 1 of the modified embodiment of the present invention can further improve the signal transmission performance using the first transmission contactor 25a 'and the second transmission contactor 25 b'.

Although not shown, the contact member 21 of the first transmission contact 25a 'may have a face and the ground plane 332 a' on the same line parallel to the third axis direction (Z axis direction). The contact member 21 of the first transfer contactor 25a 'has a face that is a face facing the contact member 21 of the first power source contactor 22 a'.

< second embodiment >

Hereinafter, a receptacle connector according to a second embodiment of the present invention will be described with reference to the drawings. A description overlapping with the receptacle connector of the first embodiment of the present invention is omitted.

The insulating portion 3 may be provided to the cover 5 so as to be located inside the cover 5. The insulating portion 3 may be provided on the cover 5 such that the front surface 3a is positioned in the insertion groove 50. Referring to fig. 30, the insulating portion 3 may be provided on the cover 5 such that the front surface 3a is positioned outside the insertion groove 50. The plug connector may be inserted into the inside of the cover 5 through the insertion groove 50 to contact the contact member 21 provided to the insulating part 3.

Referring to fig. 32 and 33, the second shielding member 42 according to the second embodiment of the present invention may be formed such that a length 42b with respect to the second axis direction (Y axis direction) is shorter than a length 42a at the other height at the same height as the mounting member 22. In this case, the second shielding member 42 may be extended by an insulating distance D3 from the mounting member 22 of the first contactor 2 a. Therefore, the receptacle connector 1 of the present invention can reduce the risk of short circuit by reducing the radiation of signals by the second shielding member 42 and increasing the insulation distance D2 between the mounting member 22 and the second shielding member 42, thereby realizing a damage prevention structure for the mounting member 22 and the second shielding member 42.

Referring to fig. 23, 24, 29, 37 to 40, the cover 5 is for accommodating the insulating part 3. The insulating portion 3 is provided in the cover 5 so as to be positioned inside the cover 5, and can be protected by the cover 5. The cover 5 may include the insertion slot 50. The plug connector can be brought into contact with the contactor 2 located inside the cover 5 by being inserted into the insertion groove 50. The cover 5 may be formed so that its front (FD arrow direction) side and rear (BD arrow direction) side are open. The open front (FD arrow direction) side of the cover 5 can communicate with the insertion groove 50. The open rear (BD arrow direction) side of the cover 5 can be shielded by the shield 4. The shield 4 may be combined with the cover 5.

The cover 5 may be made of a conductive material and may be attached to the substrate so as to be grounded. In this case, the shield 4 may be coupled to the cover 5 in such a manner that the cover 5 is grounded. Thereby, the shielding portion 4 can increase a shielding force for shielding radiation of a signal. The shield portion 4 may be mounted on the substrate in such a manner that the substrate is directly grounded.

The cover 5 may comprise a lower cover 51.

The lower cover 51 is configured to be positioned at a lower side of the insulating part 3. The lower cover 51 may be configured to shield a portion of both side surfaces of the insulating part 3 while shielding the lower surface of the insulating part 3. The first shielding member 41 may be coupled to the lower cover 51. The first shielding member 41 may be combined with the lower cover 51 in such a manner as to shield the rear surface 311 of the first support member 31. Thereby, the first shield member 41 can reduce the radiation of the signal to the rear surface 311 side of the first support member 31.

The lower cover 51 and the first shielding member 41 may be formed in one body. In this case, the first shielding member 41 may be configured to be bent (Bending) with respect to the lower cover 51 to shield the rear face 311 of the first support member 31. Thus, the receptacle connector 1 of the present invention can improve the ease with which the first shielding member 41 shields the rear surface 311 of the first supporting member 31 in a state of being grounded by the lower cover 51.

The lower cover 51 of the second embodiment of the present invention may include a lower cover body 510 and a lower support member 513.

The lower cover body 510 is combined with the insulating part 3 at the lower side of the insulating part 3. The lower cover body 510 constitutes an integral appearance of the lower cover 51.

The lower support member 513 is combined with the lower cap body 510. The lower support member 513 may be configured to face a direction parallel to the mounting surface of the substrate. For example, the lower support member 513 may be configured to be parallel to the first axis direction (X-axis direction). The lower cover body 510 may be located between the insulating portion 3 and the lower support member 513 with reference to the first axial direction (X-axis direction). The lower support member 513 may be configured to protrude outward of the insulating portion 3 with reference to the first axial direction (X-axis direction). Thus, the lower support member 513 can be supported on the substrate on both side surfaces of the insulating portion 3 with reference to the first axial direction (X-axis direction). Therefore, the socket connector of the present invention can stably maintain a state of being coupled to the substrate by supporting the lower support member 513 on the substrate.

The lower cover 51 may include a plurality of the lower support members 513. The lower support members 513 may be configured to be spaced apart from each other with reference to the first axis direction (X-axis direction). The lower support members 513 may be disposed to be spaced apart from each other with the lower cover body 510 interposed therebetween with reference to the first axial direction (X-axis direction).

The cover 5 may include an upper cover 52.

The upper cover 52 is disposed on the upper side of the insulating portion 3. The upper cover 52 may be configured to cover an upper surface of the insulating part 3 and to cover a part of both side surfaces of the insulating part 3. Both side surfaces of the insulating part 3 may be entirely covered by the upper cover 52 and the lower cover 51. The second shielding member 42 may be coupled to the upper cover 52. The second shielding member 42 may be combined with the upper cover 52 in such a manner as to shield the rear face 321 of the second support member 32. Thereby, the second shield member 42 can reduce the radiation of the signal to the rear face 321 side of the second support member 32.

The upper cover 52 and the second shielding member 42 may be formed in one body. In this case, the second shielding member 42 may be configured to be bent with respect to the upper cover 52 to shield the rear face 321 of the second support member 32. Thus, the receptacle connector 1 of the present invention can improve the ease with which the second shield member 42 shields the rear face 321 of the second support member 32 in a state of being grounded by the upper cover 52.

The upper cover 52 may include an upper mounting member 521.

The upper mounting member 521 is mounted to the substrate. The receptacle connector 1 of the present invention can be fixed to the substrate by the mounting force of the upper mounting member 521 to the substrate. The upper mounting member 521 may be inserted into a mounting groove formed on the substrate. The upper mounting member 521 may be inserted into the mounting groove and mounted so as to be fixed to the substrate by solder paste applied to the substrate. The upper mounting member 521 may be configured to face a direction perpendicular to the mounting surface of the substrate. For example, the upper mounting member 521 may be disposed parallel to the third axis direction (Z axis direction).

The upper cover 52 may include a plurality of the upper mounting members 521. In this case, the upper mounting members 521 may be disposed at positions spaced apart from each other with reference to the first axial direction (X-axis direction). Also, as shown in fig. 24, the upper mounting members 521 may be disposed at positions spaced apart from each other with reference to the second axis direction (Y axis direction). In this case, the upper mounting members 521 may be formed at positions different from each other with reference to the first axial direction (X-axis direction).

The upper cover 52 may include an upper cover body 520 and an upper support member 523.

The upper cover body 520 is combined with the insulating part 3 at an upper side of the insulating part 3. The upper cover body 520 constitutes an integral appearance of the upper cover 52.

The upper support member 523 is used in conjunction with the upper cover body 520. The upper support member 523 connects the upper cover body 520 and the upper mounting member 521. The upper support member 523 may be configured to face a direction parallel to the mounting surface of the substrate. For example, the upper support member 523 may be arranged parallel to the first axis direction (X axis direction). The upper cover body 520 may be positioned between the insulating portion 3 and the upper support member 523 with reference to the first axial direction (X-axis direction). The upper support member 523 may be configured to protrude outward of the insulating portion 3 with reference to the first axial direction (X-axis direction). Thus, the lower support member 522 can be supported on the substrate at a position spaced apart from the insulating portion 3 with respect to the first axial direction (X-axis direction).

The upper cover 52 may be configured such that the upper support member 523 is located at an upper side of the lower support member 513. Thus, the upper support member 523 can press the lower support member 513 by the mounting force of the upper mounting member 521 to the substrate. Therefore, the receptacle connector 1 of the present invention can more firmly fix the lower cover 51 to the substrate by the mounting force of the upper mounting member 521 to the substrate.

The upper cover 52 may include a plurality of the upper support members 523. The upper support members 523 may be disposed to be spaced apart from each other with reference to the first axis direction (X-axis direction). The upper support members 523 may be disposed to be spaced apart from each other with the upper cover body 520 interposed therebetween with reference to the first axial direction (X-axis direction).

The upper cover body 520 and the lower cover body 510 may be configured to be spaced apart from each other along the third axis direction (Z-axis direction), and the upper support member 523 and the lower support member 513 may be configured to be in contact with each other. Thus, the insulating portion 3 may be provided in the insertion groove 50, and the insertion groove 50 may be formed by the upper cover body 520 and the lower cover body 510 being spaced apart in the third axis direction (Z axis direction) and the upper support member 523 and the lower support member 513 being in contact with each other at positions spaced apart in the first axis direction (X axis direction).

The upper cover 52 and the lower cover 51 are formed integrally. In this case, the upper cover 52 may be configured to be bent with respect to the lower cover 51 so that a front side (FD arrow direction) where the plug connector is inserted and a rear side (BD arrow direction) where the shield 4 is coupled are opened. In this case, the upper support member 523 may be formed to be bent with respect to the lower support member 513 so that a front side (FD arrow direction) into which the plug connector is inserted and a rear side (BD arrow direction) to which the shield part 4 is coupled are opened. The upper support member 523 and the lower support member 513 include a first upper support member 523a and a first lower support member 513a, respectively, which are bent to contact each other, and include a second upper support member 523b and a second lower support member 513b, respectively, which are in contact with each other.

With reference to fig. 38 and 39, the first upper support member 523a is bent with respect to the first lower support member 513a on the right side surface of the insulating portion 3. The first upper support member 523a may be configured to be bent 180 ° with respect to the first lower support member 513a to be in contact with the upper surface of the first lower support member 513 a. The second upper support member 523b may be configured to contact the upper surface of the second lower support member 513b at the left side surface of the insulating part 3 with reference to fig. 38 and 40 as the first upper support member 523a is bent 180 ° with respect to the first lower support member 513 a. The first upper support member 523a may be bent with respect to the first lower support member 513a at a left side surface of the insulation part 3, in which case the second upper support member 523b may be configured to contact an upper surface of the second lower support member 513b at a right side surface of the insulation part 3. The second upper support member 523b and the second lower support member 513b may be coupled by performing welding in a partial manner, but are not limited thereto.

Thus, the upper cover 52 and the lower cover 51 may be formed in an integrated body which is connected by bending at one side of the insulating part 3 and has a seam 59 (shown in fig. 40) at the other side of the insulating part 3. Therefore, the receptacle connector 1 of the present invention can achieve the following operational effects.

First, the receptacle connector 1 of the present invention is integrally formed with the cover 5, so that the manufacturing process can be simplified and the manufacturing time can be reduced.

Specifically, in the case where the cover 5 is not integrally formed, that is, the lower cover 51 and the upper cover 52 are formed as separate structures, since the processes for manufacturing the lower cover 51 and the upper cover 52 are separately performed, it is necessary to separately provide a press for manufacturing the lower cover 51 and the upper cover 52. Therefore, the receptacle connector 1 of the present invention can simply realize the cover 5 by forming the lower cover 51 and the upper cover 52 by one press and bending them, thereby simplifying the manufacturing process.

Second, the receptacle connector 1 of the present invention is formed in an integral body with the joint 59 by the cover 5, which can simplify the manufacturing process and reduce the manufacturing time.

Specifically, as an example of a method used for forming the cap 5 integrally without a seam, a Metal Injection Molding (MIM) method is available. In the case of metal injection molding, the cover 5 is formed in one piece in such a manner that various metal powder materials are mixed with a binder system to produce a powder mixture of powder and binder system, and the powder mixture is formed into a product of a desired shape through an injection molding process and the binder system is removed. When the cover 5 is integrally formed by the metal injection molding method as described above, there is a problem that the metal powder used in the metal injection molding is expensive, and the amount of the binder to be added increases to maintain the fluidity of the powder during the injection molding, and thus a long time is required to remove the binder, which leads to an increase in the manufacturing cost and an increase in the manufacturing time. Therefore, in the receptacle connector 1 of the present invention, the cover 5 is formed to have the joint 59, and then the lower cover 51 and the upper cover 52 are connected by welding, so that the manufacturing process can be simplified and the manufacturing time can be shortened.

Third, the receptacle connector 1 of the present invention is realized such that the cover 5 has a seam 59 on the side surface of the insulating portion 3, and the effect of preventing radiation while simplifying the manufacturing process can be maintained.

Specifically, in the case where the joint 59 is located above or below the insulating part 3, since the first shielding member 41 combined with the lower cover 51 or the second shielding member 42 combined with the upper cover 52 also needs to be separated from the joint 59, the manufacturing process becomes complicated, and radiation can be generated through the region where the first shielding member 41 or the second shielding member 42 is separated. Therefore, in the receptacle connector 1 of the present invention, the seam 59 is formed on the side surface of the insulating portion 3, so that the effect of preventing radiation while simplifying the manufacturing process can be maintained.

As described above, by forming the seam 59 on the side of the insulating part 3, the direction in which the shielding part 4 is bent with respect to the cover 5 and the direction in which the upper cover 52 is bent with respect to the lower cover 51 may be perpendicular to each other. The shield 4 may be bent in the Y-Z plane with respect to the cover 5, and the upper cover 52 may be bent in the X-Z plane with respect to the lower cover 51. The angle at which the shield 4 is bent with respect to the cover 5 and the angle at which the upper cover 52 is bent with respect to the lower cover 51 may be different from each other. The shield 4 may be bent 90 ° with respect to the cover 5, and the upper cover 52 may be bent 180 ° with respect to the lower cover 51.

For example, since the first shielding member 41 is connected to the lower cover 51 at the lower cover 51 in a manner projecting to the second axial direction (Y-axis direction) side, which is bent in the first direction R1 (shown in fig. 30) on the Y-Z plane with reference to fig. 8, since the second shielding member 42 is connected to the upper cover 52 in a manner projecting to the second axial direction (Y-axis direction) side, which is bent in the second direction R2 (shown in fig. 30) on the Y-Z plane, at the upper cover 52. Since the first shield member 41 and the second shield member 42 need to reduce the radiation of the signal through the rear face 3b side of the insulating portion 3, they are bent by 90 °.

On the other hand, since the upper cover 52 is connected to the lower cover 51 at the lower cover 51 in a manner projecting to the first axial direction (X-axis direction) side, it is bent in the X-Z plane to the third direction R3 with reference to fig. 38. Since the upper cover 52 needs to be in contact with the upper face of the lower cover 51, it will bend 180 °.

The upper cover 52 and the lower cover 51 may include a plurality of bending regions 56 (shown in fig. 37) between the first upper support member 523a and the second lower support member 513a at one side of the insulating part 3. In this case, the bending regions 56 may be arranged to be spaced apart from each other along the second axis direction (Y-axis direction). Thus, the receptacle connector 1 of the present invention can make the upper cover 52 and the lower cover 51 more firmly coupled by the bent area 56.

In the case where the plurality of bending regions 56 are formed, as shown in fig. 37, the upper mounting member 521 formed on one side surface of the insulating portion 3 on which the bending regions 56 are formed may be disposed between the bending regions 56 with reference to the second axis direction (Y axis direction).

Referring to fig. 23, 24, 38, the cover 5 may include an inner cover 53.

The inner cover 53 is configured to be located between the cover 5 and the insulating part 3. The inner cover 53 is configured to be positioned between the upper cover 52 and the insulating part 3. The inner cover 53 is configured to be located between the lower cover 51 and the insulating part 3. The insulating part 3 may be located inside the inner cover 53. The inner cover 53 may be configured to shield the upper surface, the lower surface, and both side surfaces of the insulating part 3. Thus, the receptacle connector 1 of the present invention can shield the upper surface, the lower surface, and both side surfaces of the insulating section 3 with a double structure by the inner cover 53, the lower cover 51, and the upper cover 52, and increase a shielding force for shielding the signal radiation passing through the upper surface, the lower surface, and both side surfaces of the insulating section 3. Therefore, the receptacle connector 1 of the present invention can significantly reduce the radiation of signals through the upper surface, the lower surface, and both side surfaces of the insulating portion 3.

The inner cover 53 may be formed so that the front (FD arrow direction) side and the rear (BD arrow direction) side thereof are open. The open front side (FD arrow direction) of the inner cover 53 can communicate with the insertion groove 50. The open rear side (BD arrow direction) of the inner cover 53 can be shielded by the shield 4.

The lower cover 51 and the upper cover 52 are slidably movable along the second axis direction (Y-axis direction) to be coupled to the inner cover 53. The lower cover 51 and the inner cover 53 may be fixed by performing fusion bonding in a partial manner. The upper cover 52 and the inner cover 53 may be fixed by performing fusion bonding in a partial manner. Therefore, the receptacle connector 1 of the present invention can be configured to have a strong structure by increasing the strength of the cover 5.

The inner cover 53 may include a securing member 534 (shown in fig. 24).

The fixing member 534 fixes the insulating part 3 inserted into the insertion groove 50. The fixing member 534 is formed to protrude from the inner surface of the inner cover 53 toward the insertion groove 50 side. The fixing member 534 may be formed to protrude toward the insertion groove 50 by bending a portion of the inner cover 53. The inner cover 53 may include a plurality of the fixing members 534. In this case, the fixing members 534 may be formed to be located at positions spaced apart from each other. Fig. 24 shows that two fixing members 534 are formed on the inner cover 53, but the invention is not limited thereto.

In the case where the inner cover 53 includes the fixing member 534, the insulating part 3 may include a fixing groove 34 (shown in fig. 24). The fixing groove 34 may be formed to be recessed from the outside of the insulating part 3 by a certain depth. The insulating part 3 may be provided on the inner cover 53 in such a manner that the fixing member 534 is inserted into the fixing groove 34. The insulating part 3 may be configured to be fixed to the inner cover 53 by being supported by the fixing member 534 inserted into the fixing groove 34.

Although not shown, the inner cover 53 may include an inner mounting member. The internal mounting member may be inserted into a mounting groove formed in the substrate and mounted so as to be fixed to the substrate by solder paste applied to the substrate. In this case, the inner mounting member and the upper mounting member 521 may be arranged side by side to be inserted into one mounting groove formed on the substrate. Thus, the receptacle connector 1 of the present invention can further increase the fixing force to the substrate by increasing the mounting area on the substrate by using the internal mounting member and the upper mounting member 521.

The inner attachment member may be formed in a shape that does not interfere with the sliding movement of the lower cover 51 and the upper cover 52 to couple the inner cover 53.

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