Description

Technical Field

[0001] The present invention relates to a board connector installed in an electronic device for electrical connection between boards.

Background Art

[0002] A connector is provided in various electronic devices for electrical connection. For example, a connector is installed in an electronic device such as a mobile phone, a computer, or a tablet computer, and can electrically connect various components installed in the electronic device to each other.

[0003] Generally, inside wireless communication devices such as smartphones and tablet PCs among electronic devices, an RF connector and a board-to-board connector (hereinafter referred to as a "board connector") are provided. The RF connector transmits an RF (Radio Frequency) signal. The board connector processes digital signals such as those from a camera.

[0004] Such RF connectors and board connectors are mounted on a PCB (Printed Circuit Board). Since several board connectors and RF connectors are mounted together with a large number of components in a limited existing PCB space, there is a problem that the PCB mounting area becomes large. Therefore, along with the trend of miniaturization of smartphones, there is a need for a technology to integrate RF connectors and board connectors and optimize them with a small PCB mounting area.

[0005] FIG. 1 is a schematic perspective view of a board connector according to the prior art.

[0006] Referring to FIG. 1, a board connector 100 according to the prior art includes a first connector 110 and a second connector 120.

[0007] The first connector 110 is for coupling to a first substrate (not shown). The first connector 110 can be electrically connected to the second connector 120 through a plurality of first contacts 111.

[0008] The second connector 120 is for coupling to a second substrate (not shown). The second connector 120 can be electrically connected to the first connector 110 through a plurality of second contacts 121.

[0009] In the conventional circuit board connector 100, the first contact 111 and the second contact 121 are connected to each other, thereby electrically connecting the first circuit board and the second circuit board. Furthermore, if some of the contacts among the first contact 111 and the second contact 121 are used as RF contacts for transmitting RF signals, the conventional circuit board connector 100 can be implemented so that RF signals are transmitted between the first circuit board and the second circuit board through the RF contacts.

[0010] However, the conventional substrate connector 1 has the following problems.

[0011] Firstly, in the conventional substrate connector 1, when contacts 111 and 121 that are separated at a relatively close distance are used as the RF contacts, there is a problem in that signal transmission is not smooth due to interference of RF signals between the RF contacts 111', 111'', 121', and 121''.

[0012] Secondly, the conventional substrate connector 1 has an RF signal shielding portion 112 at the outermost part of the connector, which means that while it can shield the radiation of RF signals to the outside, it does not shield the RF signals themselves.

[0013] Thirdly, in the conventional substrate connector 1, the RF contacts 111', 111'', 121', and 121'' each include mounting parts 111a', 111a'', 121a', and 121a'' that are mounted on the substrate, but these mounting parts 111a', 111a'', 121a', and 121a'' are arranged to be exposed to the outside. Consequently, the conventional substrate connector 1 has the problem that the mounting parts 111a', 111a'', 121a', and 121a'' are not shielded. [Overview of the project] [Problems that the invention aims to solve]

[0014] This invention was devised to solve the aforementioned problems and provides a substrate connector that can reduce the possibility of RF signal interference occurring between RF contacts.

[0015] The present invention provides a substrate connector that can improve the space utilization for contact use. [Means for solving the problem]

[0016] To solve the aforementioned problems, the present invention may include the following configuration.

[0017] The substrate connector according to the present invention may include: a receptacle insulating portion; a receptacle transmission contact coupled to the receptacle insulating portion for electrical connection with a plug connector; a receptacle RF contact coupled to the receptacle insulating portion so as to be positioned away from the receptacle transmission contact for the transmission of RF signals; and a receptacle ground portion coupled to the receptacle insulating portion so as to be positioned away from the receptacle RF contact. The receptacle insulating portion may include a transmission projection that supports the receptacle transmission contact. The receptacle RF contact may include a first receptacle RF contact and a second receptacle RF contact coupled to the receptacle insulating portion so as to be positioned away from each other with the transmission projection and the receptacle transmission contact in between. The receptacle grounding portion may include a first receptacle grounding member coupled to a first side wall of the receptacle insulating portion at a position separated from the first receptacle RF contact.

[0018] In the substrate connector according to the present invention, the first receptacle grounding member may include a first receptacle grounding internal member disposed to block the inner surface of the first sidewall between the first receptacle RF contact and the first sidewall, a first receptacle grounding external member disposed to block the outer surface of the first sidewall facing in the opposite direction to the inner surface of the first sidewall, and a first receptacle grounding connecting member connecting the first receptacle grounding internal member and the first receptacle grounding external member. The first receptacle RF contact can be double-shielded through the first receptacle grounding internal member and the first receptacle grounding external member.

[0019] The substrate connector according to the present invention may include a plug insulating portion; a plug transmission contact coupled to the plug insulating portion for electrical connection with a receptacle connector; a plug RF contact coupled to the plug insulating portion so as to be positioned away from the plug transmission contact for the transmission of RF signals; and a plug ground portion coupled to the plug insulating portion so as to be positioned away from the plug RF contact. The plug RF contact may include a first plug RF contact and a second plug RF contact coupled to the plug insulating portion so as to be positioned away from each other with a transmission housing groove formed in the plug insulating portion and the plug transmission contact in between. The plug ground portion may include a first plug ground member formed to shield at least two sides of the first plug RF contact at a position away from the plug RF contact. [Effects of the Invention]

[0020] According to the present invention, the following effects can be achieved.

[0021] The present invention can improve the overall performance of a connector by being implemented in a way that reduces the possibility of interference between RF signals between RF contacts.

[0022] This invention can improve the efficiency of space utilization for contacts by securing space in which transmission contacts can be arranged.

[0023] This invention integrates a circuit board connector and an RF connector into a single unit, allowing for optimization with a smaller PCB mounting area compared to the area required for mounting existing circuit board connectors and RF connectors separately on a PCB. Therefore, because this invention enables the realization of a single process through component integration, it can increase the efficiency of the manufacturing process and relatively reduce the defect rate.

[0024] The present invention can improve the RF signal transmission performance by forming an isolation-shaped structure so that the RF signal does not interfere with the surrounding substrate signals.

[Modes for carrying out the invention]

[0026] Hereinafter, embodiments of the substrate connector according to the present invention will be described in detail with reference to the attached drawings.

[0027] Referring to Figures 2 to 7, the board connector 1 according to the present invention is installed in electronic devices (not shown) such as mobile phones, computers, and tablet computers. The board connector 1 according to the present invention is responsible for electrically connecting a first board (10A, shown in Figures 6 and 7) and a second board (10B, shown in Figures 6 and 7) in the electronic device. The first board 10A and the second board 10B may each be a printed circuit board (PCB).

[0028] Referring to Figures 2 to 5, the substrate connector 1 according to one embodiment of the present invention may include at least one of a receptacle connector 1A and a plug connector 1B.

[0029] The receptacle connector 1A can be coupled to the first substrate 10A. The receptacle connector 1A may include a receptacle insulating portion 2, a receptacle transmission contact 3 coupled to the receptacle insulating portion 2 for transmitting signals such as data, a receptacle RF contact 4 coupled to the receptacle insulating portion 2 at a position away from the receptacle transmission contact 3 for transmitting RF signals, and a receptacle grounding portion 5 coupled to the receptacle insulating portion 2 for grounding.

[0030] The plug connector 1B can be coupled to the second substrate 10B. The plug connector 1B may include a plug insulating portion 6, a plug transmission contact 7 for electrical connection with the receptacle connector 1A, a plug RF contact 8 coupled to the plug insulating portion 6 so as to be spaced away from the plug transmission contact 7 and for transmitting RF signals, and a plug ground portion 9 coupled to the plug insulating portion 6 so as to be spaced away from the plug RF contact 8.

[0031] The plug connector 1B is coupled to the receptacle connector 1A, thereby electrically connecting the first substrate 10A and the second substrate 10B. For example, the substrate connector 1 according to the present invention is implemented so that signals such as data are transmitted between the first substrate 10A and the second substrate 10B by connecting the receptacle transmission contact 3 and the plug transmission contact 7 to each other. Alternatively, the substrate connector 1 according to the present invention is implemented so that RF signals are transmitted between the first substrate 10A and the second substrate 10B by connecting the receptacle RF contact 4 and the plug RF contact 8 to each other.

[0032] Referring to Figures 2 to 7, in the substrate connector 1 according to the present invention, the receptacle RF contact 4 may include a first receptacle RF contact 41 and a second receptacle RF contact 42. The first receptacle RF contact 41 and the second receptacle RF contact 42 may be coupled to the receptacle insulating portion 2. The first receptacle RF contact 41 and the second receptacle RF contact 42 may be arranged to be separated from each other with the receptacle transmission contact 3 in between. Accordingly, the substrate connector 1 according to the present invention can achieve the following effects.

[0033] Firstly, the substrate connector 1 according to the present invention can be implemented such that the first receptacle RF contact 41 and the second receptacle RF contact 42 are spaced a predetermined distance apart from the receptacle transmission contact 3. Accordingly, the substrate connector 1 according to the present invention can reduce the possibility of interference between RF signals between the RF contacts compared to the conventional technology in which the contacts for RF signal transmission are arranged relatively close together. Therefore, the substrate connector 1 according to the present invention can improve the overall performance of the connector by ensuring the stability of RF signal transmission.

[0034] Secondly, the substrate connector 1 according to the present invention is implemented such that the receptacle transmission contact 3 is positioned in the space between the first receptacle RF contact 41 and the second receptacle RF contact 42. Accordingly, the substrate connector 1 according to the present invention improves the stability of RF signal transmission by increasing the isolation distance between the first receptacle RF contact 41 and the second receptacle RF contact 42, and also secures space in which the receptacle transmission contact 3 can be positioned. Therefore, the substrate connector 1 according to the present invention can improve the efficiency of space utilization for contact use.

[0035] The receptacle insulation portion 2, the receptacle transmission contact 3, the receptacle RF contact 4, the receptacle grounding portion 5, the plug insulation portion 6, the plug transmission contact 7, the plug RF contact 8, and the plug grounding portion 9 will be described in detail below with reference to the attached drawings. On the other hand, it will be obvious to those with ordinary skill in the art to which the present invention pertains that the terms "one side" and "other side" as used herein are for distinguishing each component and do not indicate a particular direction. Furthermore, the terms "plug" and "receptacle" do not limit the uses and functions of the receptacle connector 1A and the plug connector 1B.

[0036] Referring to Figures 2 to 10, the receptacle insulating portion 2 is for coupling to the first substrate 10A. The receptacle insulating portion 2 can be coupled to the first substrate 10A through the receptacle grounding portion 5. The receptacle insulating portion 2 can support the receptacle transmission contact 3 and the receptacle RF contact 4 by coupling them to the receptacle insulating portion 2. Multiple receptacle transmission contacts 3 can be coupled to the receptacle insulating portion 2. In this case, the receptacle transmission contacts 3 can be arranged to be spaced apart from each other along the first axial direction (X-axis direction). The first axial direction (X-axis direction) may be the same direction as the relatively long length direction of the receptacle insulating portion 2. Multiple receptacle transmission contacts 3 can be arranged in rows along the first axial direction (X-axis direction) to be spaced apart from each other along the first axial direction (X-axis direction) of the receptacle insulating portion 2. For example, as shown in Figure 4, the receptacle transmission contacts 3 may be arranged in two rows in the receptacle insulation portion 2, spaced apart from each other along the first axial direction (X-axis direction). The receptacle insulation portion 2 may be made of a material having electrical insulating properties. The receptacle insulation portion 2 may be formed in the form of a rectangular parallelepiped as a whole.

[0037] The receptacle insulating portion 2 may include a first transmission coupling groove (not shown). The receptacle transmission contact 3 can be coupled to the receptacle insulating portion 2 by being inserted into the first transmission coupling groove. The receptacle insulating portion 2 and the receptacle transmission contact 3 may be coupled through insert molding. The first transmission coupling groove may be formed in the receptacle insulating member 20 of the receptacle insulating portion 2. The receptacle insulating member 20 can function as the body of the receptacle insulating portion 2. If the substrate connector 1 according to the present invention includes a plurality of the receptacle transmission contacts 3, the receptacle insulating portion 2 may include a plurality of the first transmission coupling grooves. The receptacle insulating portion 2 may include the same number of first transmission coupling grooves as the number of receptacle transmission contacts 3.

[0038] The receptacle insulating portion 2 may include a first RF coupling groove (not shown). The receptacle RF contact 4 can be coupled to the receptacle insulating portion 2 by being inserted into the first RF coupling groove. The receptacle insulating portion 2 and the receptacle RF contact 4 may be coupled through insert molding. The first RF coupling groove may be formed in the receptacle insulating member 20. If the receptacle RF contact 4 includes a plurality of RF contacts, the receptacle insulating portion 2 may include a plurality of the first RF coupling grooves. The receptacle insulating portion 2 may include the same number of first RF coupling grooves as the number of RF contacts belonging to the receptacle RF contact 4.

[0039] Referring to Figure 8, the receptacle insulating portion 2 can include a transmission projection 21 and an RF projection 22.

[0040] The transmission projection 21 supports the receptacle transmission contact 3. The receptacle transmission contact 3 can be coupled to the transmission projection 21. The transmission projection 21 and the receptacle transmission contact 3 may be coupled to each other by insert molding. The transmission projection 21 may protrude in a first direction (FD arrow direction). The first direction (FD arrow direction) is the same direction in which the overall height of the substrate connector 1 according to the present invention increases, and may also be the direction from the receptacle insulating portion 2 to the plug insulating portion 6. The transmission projection 21 may be formed at an intermediate point of the receptacle insulating member 20. The transmission projection 21 may be formed in the form of a rectangular parallelepiped as a whole. A part of the first transmission coupling groove may be formed on the transmission projection 21.

[0041] The RF projection 22 supports the receptacle RF contact 4. The receptacle RF contact 4 is coupled to the RF projection 22. The RF projection 22 and the receptacle RF contact 4 may be coupled to each other by insert molding. The RF projection 22 may protrude in the first direction (direction of the FD arrow).

[0042] The RF projection 22 may be formed at a position spaced apart from the transmission projection 21. If the receptacle RF contact 4 includes a plurality of RF contacts, the receptacle insulating portion 2 may include a plurality of RF projections 22. For example, if the receptacle RF contact 4 includes two RF contacts 41 and 42, the RF projection 22 may include a first RF projection 221 and a second RF projection 222. In this case, the first RF projection 221 and the second RF projection 222 may be arranged spaced apart from each other with respect to the first axial direction (X-axis direction) with respect to the transmission projection 21 as the center, as shown in Figure 8. The first RF projection 221 may support the first receptacle RF contact 41, and the second RF projection 222 may support the second receptacle RF contact 42. The first RF projection 221 and the second RF projection 222 may be embodied in the same form as each other.

[0043] Referring to Figures 8 and 9, the receptacle insulating portion 2 may include a mounting groove 23.

[0044] The mounting groove 23 is formed between the receptacle ground portion 5 and the receptacle RF contact 4. The plug ground portion 9 of the plug insulating portion 6 is inserted into the mounting groove 23. The plug insulating portion 6 can be coupled to the receptacle insulating portion 2 by the insertion of the plug ground portion 9 into the mounting groove 23. The mounting groove 23 may be formed such that the receptacle ground portion 5 is positioned on the outside and the transmission projection 21 and the RF projection 22 are positioned on the inside. The mounting groove 23 may be formed to be located between the first transmission coupling grooves which are arranged in a plurality of rows.

[0045] Referring to Figure 10, a receptacle injection groove 24 may be formed in the receptacle insulating portion 2.

[0046] The receptacle injection groove 24 may be a portion into which injection resin for forming the receptacle insulating portion 2 is injected. The receptacle injection groove 24 may be formed at an intermediate point in the receptacle insulating member 20. The receptacle injection groove 24 may be formed by recessing to a predetermined depth from the lower surface of the receptacle insulating member 20. The receptacle injection groove 24 may be spaced apart from the first substrate 10A. The receptacle injection groove 24 may be formed in the form of a rectangular parallelepiped as a whole. The receptacle injection groove 24 may be formed at the same distance from the first receptacle RF contact 41 and the second receptacle RF contact 42, respectively.

[0047] Referring to Figure 8, the receptacle insulating portion 2 may include a receptacle fixing groove 25.

[0048] The receptacle fixing groove 25 into which the receptacle grounding portion 5 is inserted. The receptacle grounding portion 5 can be coupled to the receptacle insulating portion 2 by being inserted into the receptacle fixing groove 25. Accordingly, the substrate connector 1 according to the present invention can improve the coupling force between the receptacle grounding portion 5 and the receptacle insulating portion 2 by ensuring that the receptacle grounding portion 5 is fixed to the receptacle insulating portion 2 even when vibration or shaking occurs. The receptacle fixing groove 25 can be formed by machining a groove of a predetermined depth from the upper surface of the receptacle insulating portion 2.

[0049] Referring to Figures 2 to 10, 17 and 18, the receptacle transmission contact 3 is mounted on the first substrate 10A. The receptacle transmission contact 3 can be connected to the plug transmission contact 7. Accordingly, data signals or power signals can be transmitted between the first substrate 10A and the second substrate 10B. The receptacle transmission contact 3 can be made of a conductive material.

[0050] The receptacle transmission contact 3 is coupled to the receptacle insulation part 2. The receptacle transmission contact 3 may be coupled to the transmission projection 21. Multiple receptacle transmission contacts 3 may be coupled to the receptacle insulation part 2. The receptacle transmission contacts 3 may be coupled to the receptacle insulation part 2 in multiple rows, spaced apart in the first axial direction (X-axis direction). Figure 4 illustrates a configuration in which four receptacle transmission contacts 3 are coupled to the receptacle insulation part 2 in two rows along the second axial direction (Y-axis direction), spaced apart along the first axial direction (X-axis direction). The second axial direction (Y-axis direction) is perpendicular to the first axial direction (X-axis direction) and may be the same direction as the width direction, which is relatively shorter in length in the receptacle insulation part 2. The transmission projection 21 may be positioned between multiple rows of receptacle transmission contacts 3. Since all of the aforementioned receptacle transmission contacts 3 are implemented to have the same form and function, the following description will be based on one of the aforementioned receptacle transmission contacts 3.

[0051] Referring to Figures 2 to 20, the receptacle RF contact 4 is for transmitting RF signals. The receptacle RF contact 4 is positioned at a distance from the receptacle transmission contact 3. The receptacle RF contact 4 is mounted on the first substrate 10A and can be connected to the plug RF contact 8. Accordingly, data signals or power signals can be transmitted between the first substrate 10A and the second substrate 10B.

[0052] The receptacle RF contact 4 is coupled to the receptacle insulating portion 2. The receptacle RF contact 4 can be coupled to the RF projection 22. In the following description, the receptacle RF contact 4 will be described based on the case in which two RF contacts 41 and 42 are included, but it will be obvious to those ordinary skill in the art to which the present invention belongs that embodiments of the substrate connector 1 according to the present invention, in which the receptacle RF contact 4 includes three or more RF contacts, can be derived from this.

[0053] Referring to Figures 8 to 10, the receptacle RF contact 4 can include the first receptacle RF contact 41 and the second receptacle RF contact 42.

[0054] The first receptacle RF contact 41 may be an RF contact positioned on one side with respect to the receptacle transmission contact 3. In this case, the second receptacle RF contact 42 may be an RF contact positioned on the other side with respect to the receptacle transmission contact 3. For example, as shown in Figure 9, if the first receptacle RF contact 41 is positioned to the left with respect to the receptacle transmission contact 3, the second plug RF contact 82 may be positioned to the right with respect to the receptacle transmission contact 3. The first receptacle RF contact 41 may be coupled to the receptacle insulation portion 2. The first receptacle RF contact 41 may be coupled to the first RF projection 221. The first receptacle RF contact 41 may be formed of a conductive material.

[0055] Referring to Figures 4 and 8-10, the second receptacle RF contact 42 is positioned at a distance from the first receptacle RF contact 41. The second receptacle RF contact 42 and the first receptacle RF contact 41 can be positioned at a distance from each other, with the transmission projection 21 and the receptacle transmission contact 3 in between. Accordingly, the substrate connector 1 according to the present invention can further reduce the possibility of RF signal interference between the RF contacts by utilizing the transmission projection 21 and the receptacle transmission contact 3. Therefore, the substrate connector 1 according to the present invention can further improve the overall performance of the connector by further improving the stability of RF signal transmission. Furthermore, the substrate connector 1 according to the present invention can further increase the isolation distance between the first receptacle RF contact 41 and the second receptacle RF contact 42 by utilizing the transmission projection 21 and the receptacle transmission contact 3. Therefore, the substrate connector 1 according to the present invention can improve the stability of RF signal transmission and secure space in which the receptacle transmission contact 3 can be positioned. Therefore, the substrate connector 1 according to the present invention can further improve the degree of space utilization for the use of contacts.

[0056] The second receptacle RF contact 42 may be coupled to the receptacle insulating portion 2. The second receptacle RF contact 42 may be coupled to the second RF projection 222. The second receptacle RF contact 42 may be formed of a conductive material. The second receptacle RF contact 42 may be substantially identical to the first receptacle RF contact 41, except for its position.

[0057] Referring to Figures 4 and 6 to 12, the receptacle grounding portion 5 is for grounding to the plug grounding portion 9. The receptacle grounding portion 5 can be coupled to the receptacle insulating portion 2 so as to be separated from the receptacle RF contact 4.

[0058] The receptacle grounding portion 5 can be formed to surround the side of the receptacle RF contact 4. Accordingly, the substrate connector 1 according to the present invention can embody a physical barrier that shields RF electromagnetic waves radiated from the receptacle RF contact 4 from flowing to the outside through the receptacle grounding portion 5. Therefore, the substrate connector 1 according to the present invention can contribute to improving the performance of adjacent electronic devices.

[0059] The transmission projection 21 and the RF projection 22 can be located inside the receptacle grounding portion 5. The mounting groove 23 can be formed between the receptacle grounding portion 5 and the projections 21 and 22. The receptacle grounding portion 5 may be formed as a wall extending from the lower surface of the receptacle insulating member 20 in the first direction (direction of the FD arrow). The receptacle grounding portion 5 may be made of a metal material.

[0060] Referring to Figures 8 to 10, the receptacle grounding portion 5 may include the first receptacle grounding member 51.

[0061] The first receptacle grounding member 51 may be positioned at a distance from the first receptacle RF contact 41 and positioned to block at least two sides of the first receptacle RF contact 41. Accordingly, the substrate connector 1 according to the present invention can embody a shielding force that blocks RF electromagnetic waves radiated from the first receptacle RF contact 41 from flowing to the outside through the first receptacle grounding member 51. In this case, the first receptacle grounding member 51 may be embodied in a polygonal structure including three or more faces.

[0062] The first receptacle grounding member 51 may be formed at a position spaced apart from the first receptacle RF contact 41 and to shield the first receptacle RF contact 41 from all sides. In this case, the first receptacle RF contact 41 can be located inside the first receptacle grounding member 51. Accordingly, the substrate connector 1 according to the present invention can further enhance the shielding force using the first receptacle grounding member 51. The first receptacle grounding member 51 may be formed at a position spaced apart from the first receptacle RF contact 41 and to shield the first receptacle RF contact 41 from all four sides.

[0063] Referring to Figures 8 to 12, a receptacle cutting hole 4a can be formed between the first receptacle grounding member 51 and the first receptacle RF contact 41. The first receptacle grounding member 51 and the first receptacle RF contact 41 can be separated from each other with respect to the receptacle cutting hole 4a. If the first receptacle grounding member 51 and the first receptacle RF contact 41 are integrally formed through a single plate material, the receptacle cutting hole 4a can be formed in a single pressing operation. Accordingly, the substrate connector 1 according to the present invention can improve the ease of manufacturing of the first receptacle grounding member 51 and the first receptacle RF contact 41, and can reduce the possibility of the first receptacle grounding member 51 and the first receptacle RF contact 41 being grounded to each other through the receptacle cutting hole 4a. Therefore, the substrate connector 1 according to the present invention can improve the performance of both the first receptacle grounding member 51 and the first receptacle RF contact 41.

[0064] The receptacle cutting holes 4a may be formed one on each side centered on the first receptacle RF contact 41 and the second receptacle RF contact 42, respectively. If the receptacle RF contact 4 includes two RF contacts 41 and 42, the substrate connector 1 according to the present invention may include four receptacle cutting holes 4a. Figure 9 illustrates four of the receptacle cutting holes 4a, but this is illustrative, and the substrate connector 1 according to the present invention may include one to three receptacle cutting holes 4a, or five or more receptacle cutting holes 4a.

[0065] The receptacle cutting hole 4a may communicate with a receptacle communication hole (26, shown in Figure 12) formed in the receptacle insulating portion 2. The receptacle communication hole 26 may be formed to be larger than the receptacle cutting hole 4a. The receptacle communication hole 26 may be formed in the form of a rectangular parallelepiped as a whole. The receptacle communication hole 26 may be positioned on the first direction (FD arrow direction) side relative to the receptacle cutting hole 4a. The receptacle communication hole 26 and the receptacle cutting hole 4a may be formed together through a single press working process.

[0066] Referring to Figures 9 to 12, the first receptacle grounding member 51 may include the first receptacle grounding mounting member 511.

[0067] The first receptacle grounding mounting member 511 is mounted on the first substrate 10A. The first receptacle grounding member 51 can be mounted on the first substrate 10A through the first receptacle grounding mounting member 511.

[0091] The second receptacle grounding member 52 may be coupled to the second sidewall 202 at a position spaced apart from the second receptacle RF contact 42. Accordingly, the second receptacle grounding member 52 may be positioned to shield at least two sides of the second receptacle RF contact 42 at a position spaced apart from the second receptacle RF contact 42. Therefore, the second receptacle grounding member 52 can embody a shielding force that blocks RF electromagnetic waves radiated from the second receptacle RF contact 42 from flowing to the outside. If the second sidewall 202 includes a plurality of second sidewall members, the second receptacle grounding member 52 may be coupled to at least two of the second sidewall members.

[0103] Referring to Figure 14, the plug insulation portion 6 may include a transmission accommodation groove 61 and an RF accommodation groove 62.

[0104] The transmission housing groove 61 into which the transmission projection 21 is inserted. By inserting the transmission projection 21 into the transmission housing groove 61, the plug transmission contact 7 and the receptacle transmission contact 3 can be connected to each other. The transmission housing groove 61 may be formed in a form corresponding to the transmission projection 21 so that the transmission projection 21 is inserted. The transmission housing groove 61 may be formed such that the plug transmission contact 7 and the second transmission coupling groove (not shown) are located on the outside. The transmission housing groove 61 may be located at the midpoint of the plug insulation portion 6. The transmission housing groove 61 may be formed in the form of a rectangular parallelepiped as a whole.

[0105] The RF housing groove 62 is into which the RF projection 22 is inserted. The plug RF contact 8 and the receptacle RF contact 4 can be connected to each other by inserting the transmission projection 21 into the RF housing groove 62. The RF housing groove 62 may be formed in a manner corresponding to the RF projection 22 so that the RF projection 22 is inserted. The RF housing groove 62 may be located at a distance from the transmission housing groove 61. The RF housing groove 62 may be formed in the form of a rectangular parallelepiped as a whole. If the RF projection 22 includes two RF projections 221 and 222, the RF housing groove 62 may include a first RF housing groove 621 and a second RF housing groove 622. In this case, the first RF projection 221 may be inserted into the first RF housing groove 621 and the second RF projection 222 may be inserted into the second RF housing groove 622. The first RF housing groove 621 and the second RF housing groove 622 may be arranged to be spaced apart with respect to the transmission housing groove 61.

[0107] Referring to Figures 9 and 13, if the plug insulation portion 6 includes the transmission housing groove 61 and the RF housing groove 62, the transmission projection 21 and the RF projection 22 can be embodied as follows.

[0108] The transmission projection 21 may be formed to protrude from the lower surface 2a of the receptacle insulating portion 2 by a first projection distance 21L. The first projection distance 21L may be a distance with respect to the third axis direction (Z axis direction). The third axis direction (Z axis direction) is a direction parallel to the first direction (FD arrow direction) and the second direction (SD arrow direction), and may also be a direction perpendicular to the first axis direction (X axis direction) and the second axis direction (Y axis direction).

[0109] If the transmission projection 21 is formed to protrude from the lower surface 2a of the receptacle insulating portion 2 by a first projection distance 21L, the RF projection 22 may be formed to protrude from the lower surface 2a of the receptacle insulating portion 2 by a second projection distance 22L, which is shorter than the first projection distance 21L. That is, with respect to the third axis direction (Z axis direction), the transmission projection 21 may be formed to be even higher than the RF projection 22. Accordingly, in the process of coupling the receptacle connector 1A and the plug connector 1B together, the transmission projection 21 can be coupled before the RF projection 22, thereby embodying a guide function and alignment function. Therefore, in the process of coupling the receptacle connector 1A and the plug connector 1B together, the transmission projection 21 can prevent damage or breakage to the RF contact portions 4 and 8, which are impedance matching sensitive elements, thereby preventing a decrease in the high-frequency transmission performance embodied through the RF contact portions 4 and 8. Furthermore, if the receptacle connector 1A and the plug connector 1B are connected in a misaligned state, the impact caused by the misalignment will be applied to the transmission projection 21 first. This reduces the impact applied to the RF projection 22 and the RF contact portions 4 and 8 due to the misalignment. Although not shown in the figures, the transmission projection 21 and the RF projection 22 may be formed to protrude from the lower surface 2a of the receptacle insulating portion 2 by the same protrusion distance.

Multiple plug transmission contacts 7 may be coupled to the plug insulation portion 6 in rows, spaced apart in the first axial direction (X-axis direction). Figure 5 illustrates a configuration in which four plug transmission contacts 7 are coupled to the plug insulation portion 6 in two rows spaced apart in the second axial direction (Y-axis direction), spaced apart along the first axial direction (X-axis direction). The transmission housing groove 61 can be located between multiple rows of plug transmission contacts 7. Since all plug transmission contacts 7 are implemented to have the same form and function, the following description will be based on one plug transmission contact 7.

The plug transmission connecting member 73, the plug transmission mounting member 72 and the plug transmission connecting member 71 may be formed integrally. An elastic groove 74 may be formed between the plug transmission connecting member 73 and the plug transmission connecting member 71. Accordingly, the plug transmission connecting member 73 and the plug transmission connecting member 71 can move elastically in the second axial direction (Y-axis direction) as the receptacle transmission contact 3 and the plug transmission contact 7 are connected to each other.

[0119] Referring to Figures 17 and 18, the receptacle transmission contact 3 may have the following configuration in order to connect the plug transmission contact 7 and the receptacle transmission contact 3 to each other.

[0120] The receptacle transmission contact 3 may include a receptacle transmission connection member 31.

[0121] The receptacle transmission connection member 31 is connected to the plug transmission contact 7 for electrical connection between the first substrate 10A and the second substrate 10B. The receptacle transmission connection member 31 may be connected to the plug transmission connection member 71. The receptacle transmission contact 3 may be coupled to the receptacle insulating portion 2 such that the receptacle transmission connection member 31 is positioned in the mounting groove 23, as shown in Figure 9. The receptacle transmission connection member 31 may be made of a conductive material.

[0122] Referring to Figures 17 and 18, the receptacle transmission connection member 31 may include a first receptacle transmission branching member 311 and a second receptacle transmission branching member 312.

[0123] The first receptacle transmission branching member 311 is connected to the plug transmission contact 7. The first receptacle transmission branching member 311 can be coupled to and connected to the plug transmission connecting member 71. The first receptacle transmission branching member 311 can be formed as a curved surface. As shown in Figures 17 and 18, the first receptacle transmission branching member 311 can be formed as a curved surface with respect to the second axial direction (Y-axis direction). Accordingly, the first receptacle transmission branching member 311 can move at least one of the receptacle transmission contact 3 and the plug transmission contact 7 in the second axial direction (Y-axis direction). For example, if the plug transmission contact 7 is misaligned to the left with respect to the second axial direction (Y-axis direction) relative to Figure 17, the plug transmission contact 7 will move to the right along the curved surface formed by the first receptacle transmission branching member 311 after contacting it. Therefore, the substrate connector 1 according to the present invention can improve the accuracy and ease of connecting the receptacle transmission contact 3 and the plug transmission contact 7.

[0124] The second receptacle transmission branching member 312 is positioned at a distance from the first receptacle transmission branching member 311. The second receptacle transmission branching member 312 and the first receptacle transmission branching member 311 may be positioned at a distance from each other in the second axial direction (Y-axis direction). The second receptacle transmission branching member 312 may be connected to the plug transmission connecting member 73. Accordingly, the substrate connector 1 according to the present invention is implemented with a so-called double contact structure in which the receptacle transmission contact 3 and the plug transmission contact 7 make contact at multiple different positions, thereby improving connection reliability and contact stability for the receptacle transmission contact 3 and the plug transmission contact 7.

[0125] The second receptacle transmission branching member 312 can be formed as a curved surface. As shown in Figures 17 and 18, the second receptacle transmission branching member 312 can be formed as a curved surface with respect to the second axial direction (Y-axis direction). Accordingly, if the positions of the receptacle transmission contact 3 and the plug transmission contact 7 are misaligned within a predetermined range in the second axial direction (Y-axis direction), the second receptacle transmission branching member 312 can move at least one of the receptacle transmission contact 3 and the plug transmission contact 7. For example, if the plug transmission contact 7 is misaligned to the right with respect to the second axial direction (Y-axis direction) with respect to Figure 17, the plug transmission contact 7 will contact the second receptacle transmission branching member 312 and then move to the left along the curved surface formed by the second receptacle transmission branching member 312. Therefore, the substrate connector 1 according to the present invention can further improve the accuracy and ease of connecting the receptacle transmission contact 3 and the plug transmission contact 7.

[0126] Referring to Figures 17 and 18, the receptacle transmission connection member 31 may include a transmission insertion groove 313.

[0127] The transmission insertion groove 313 is formed between the first receptacle transmission branching member 311 and the second receptacle transmission branching member 312. In this case, the connection between the receptacle transmission contact 3 and the plug transmission contact 7 can be made by inserting the plug transmission contact 7 into the transmission insertion groove 313. In this case, the receptacle transmission contact 3 can function as a receptacle contact, and the plug transmission contact 7 can function as a plug contact. The first receptacle transmission branching member 311 and the second receptacle transmission branching member 312 are formed with curved surfaces to guide the receptacle transmission connecting member 31 into the transmission insertion groove 313. Although not shown, if the transmission insertion groove 313 is formed in the plug transmission contact 7, the receptacle transmission contact 3 can function as a plug contact, and the plug transmission contact 7 can function as a receptacle contact.

[0128] Referring to Figures 17 and 18, the receptacle transmission connection member 31 may include a receptacle transmission linking member 314.

[0129] The receptacle transmission connecting member 314 connects the second receptacle transmission branching member 312 and the first receptacle transmission branching member 311 so that the second receptacle transmission branching member 312 moves elastically. The transmission insertion groove 313 can be located inside the receptacle transmission connecting member 314, the second receptacle transmission branching member 312, and the first receptacle transmission branching member 311. Therefore, the second receptacle transmission branching member 312 moves away from the first receptacle transmission branching member 311 as it is pushed by the plug transmission connecting member 73 during the process in which the plug transmission connecting member 71 and the plug transmission connecting member 73 are inserted into the transmission insertion groove 313. When the plug transmission connection member 71 and the plug transmission linking member 73 are inserted into the transmission insertion groove 313, the second receptacle transmission branching member 312 moves toward the first receptacle transmission branching member 311 through a restoring force. Accordingly, the second receptacle transmission branching member 312 elastically pressurizes the plug transmission linking member 73, thereby firmly maintaining the state in which the receptacle transmission contact 3 and the plug transmission contact 7 are connected to each other. The receptacle transmission linking member 314, the second receptacle transmission branching member 312, and the first receptacle transmission branching member 311 may be formed integrally.

[0130] Referring to Figures 17 and 18, the receptacle transmission contact 3 may include the receptacle transmission mounting member 32.

[0131] The receptacle transmission mounting member 32 is intended to be mounted on the first substrate 10A. The receptacle transmission contact 3 is electrically connected to the first substrate 10A when the receptacle transmission mounting member 32 is mounted on the first substrate 10A. The receptacle transmission mounting member 32 may be made of a conductive material. The receptacle transmission mounting member 32 is connected to the receptacle transmission connection member 31. The receptacle transmission mounting member 32 may be formed to be connected to the first receptacle transmission branch member 311. In this case, the first receptacle transmission branch member 311 is positioned between the receptacle transmission mounting member 32 and the second receptacle transmission branch member 312. The receptacle transmission mounting member 32 may be formed integrally with the receptacle transmission connection member 31.

[0132] Referring to Figures 2 to 20, the plug RF contact 8 is for transmitting RF signals. The plug RF contact 8 is positioned at a distance from the plug transmission contact 7. The plug RF contact 8 is mounted on the second substrate 10B and can be connected to the receptacle RF contact 4. Accordingly, data signals or power signals can be transmitted between the first substrate 10A and the second substrate 10B.

[0133] The plug RF contact 8 is coupled to the plug insulating portion 6. The plug RF contact 8 can be housed in the RF housing groove 62. In the following description, the plug RF contact 8 will be described based on the case in which two RF contacts 81 and 82 are included, but it will be obvious to those ordinary skill in the art to which the present invention belongs that embodiments of the substrate connector 1 according to the present invention, in which the plug RF contact 8 includes three or more RF contacts, can be derived from this.

[0134] Referring to Figures 14 to 16, the plug RF contact 8 can include the first plug RF contact 81 and the second plug RF contact 82.

[0135] The first plug RF contact 81 may be an RF contact positioned on one side with respect to the plug transmission contact 7. In this case, the second plug RF contact 82 may be an RF contact positioned on the other side with respect to the plug transmission contact 7. For example, as shown in Figure 15, if the first plug RF contact 81 is positioned to the left with respect to the plug transmission contact 7, the second plug RF contact 82 may be positioned to the right with respect to the plug transmission contact 7. The first plug RF contact 81 may be coupled to the plug insulation portion 6. The first plug RF contact 81 may be housed in the first RF housing groove 621. The first plug RF contact 81 may be formed of a conductive material.

[0136] The first plug RF contact 81 and the second plug RF contact 82 can be arranged to be spaced apart from each other, with the transmission groove 61 and the plug transmission contact 7 in between. Accordingly, the substrate connector 1 according to the present invention can reduce the possibility of RF signal interference between the RF contacts compared to the conventional technology in which the contacts for RF signal transmission are arranged relatively close together. Therefore, the substrate connector 1 according to the present invention can improve the overall performance of the connector by ensuring the stability of RF signal transmission. Furthermore, the substrate connector 1 according to the present invention can increase the isolation distance between the first plug RF contact 81 and the second plug RF contact 82 by utilizing the transmission groove 61 and the plug transmission contact 7. Therefore, the substrate connector 1 according to the present invention can improve the stability of RF signal transmission and secure space in which the plug transmission contact 7 can be arranged. Therefore, the substrate connector 1 according to the present invention can improve the space utilization of the contacts.

[0137] The first plug RF contact 81 is positioned to connect to the first receptacle RF contact 41, corresponding to the first receptacle RF contact 41. For the first plug RF contact 81 and the first receptacle RF contact 41 to connect to each other, the first receptacle RF contact 41 and the first plug RF contact 81 may each include the following configurations:

[0138] Referring to Figures 19 and 20, the first receptacle RF contact 41 may include the first receptacle RF connecting member 411.

[0139] The first receptacle RF connector 411 is connected to the first plug RF contact 81 for electrical connection between the first substrate 10A and the second substrate 10B. The first receptacle RF contact 41 can be coupled to the receptacle insulating portion 2 such that the first receptacle RF connector 411 is coupled to the first RF projection 221. The first receptacle RF connector 411 may be formed of a conductive material. The first receptacle RF connector 411 may be formed in the shape of an inverted "U" overall.

[0140] The first receptacle RF connecting member 411 may include a first-first receptacle RF branching member 4111 and a first-second receptacle RF branching member 4112.

[0141] The 1-1 receptacle RF branching member 4111 is connected to the first plug RF contact 81. The 1-1 receptacle RF branching member 4111 can be coupled to the first plug RF contact 81 and connected to the first plug RF contact 81.

[0142] The 1-2 receptacle RF branching member 4112 is connected to the first plug RF contact 81 at a position separated from the 1-1 receptacle RF branching member 4111. The 1-2 receptacle RF branching member 4112 and the 1-1 receptacle RF branching member 4111 can be arranged separated from each other in the second axial direction (Y-axis direction). Accordingly, the substrate connector 1 according to the present invention is implemented with a so-called double contact structure in which the first receptacle RF contact 41 and the first plug RF contact 81 make contact at multiple different positions, thereby improving the connection reliability and contact stability of the first receptacle RF contact 41 and the first plug RF contact 81.

[0143] The first receptacle RF connecting member 411 may include the first receptacle RF linking member 4113.

[0144] The first receptacle RF connecting member 4113 is connected to the 1-1 receptacle RF branching member 4111 and the 1-2 receptacle RF branching member 4112, respectively. The first receptacle RF connecting member 4113 may be positioned between the 1-1 receptacle RF branching member 4111 and the 1-2 receptacle RF branching member 4112. In this case, the 1-1 receptacle RF branching member 4111 and the 1-2 receptacle RF branching member 4112 may be positioned symmetrically with respect to the first receptacle RF connecting member 4113. The first receptacle RF connecting member 4113 may be connected at a right angle to the 1-1 receptacle RF branching member 4111 and the 1-2 receptacle RF branching member 4112, respectively. The first receptacle RF connecting member 4113, the first-to-second receptacle RF branching member 4112, and the first-to-first receptacle RF branching member 4111 may be formed integrally.

[0145] Referring to Figures 19 and 20, the first receptacle RF contact 41 may include the first receptacle RF mounting member 412.

[0146] The first receptacle RF mounting member 412 is intended to be mounted on the first substrate 10A. The first receptacle RF contact 41 is electrically connected to the first substrate 10A when the first receptacle RF mounting member 412 is mounted on the first substrate 10A. The first receptacle RF mounting member 412 may be made of a conductive material. The first receptacle RF mounting member 412 is connected to the first receptacle RF connecting member 411.

[0147] The first receptacle RF mounting member 412 may be formed to be even smaller than the first receptacle RF connecting member 411. Accordingly, the substrate connector 1 according to the present invention can reduce the size of the first PCB pattern (not shown) formed on the first substrate 10A on which the first receptacle RF mounting member 412 is mounted. Therefore, the substrate connector 1 according to the present invention can reduce the manufacturing cost for forming the first PCB pattern. The first receptacle RF mounting member 412 may be formed to be even shorter in length than the first receptacle RF connecting member 411 with respect to the first axial direction (X-axis direction).

[0148] Referring to Figures 19 and 20, the first plug RF contact 81 may include the first plug RF connecting member 811.

[0149] The first plug RF connector 811 is connected to the first receptacle RF connector 411 for electrical connection between the first substrate 10A and the second substrate 10B. The first plug RF contact 81 can be coupled to the plug insulating portion 6 so that the first plug RF connector 811 is housed in the first RF housing groove 621. The first plug RF connector 811 may be made of a conductive material.

[0150] The first plug RF connecting member 811 may include a 1-1 plug RF branching member 8111, a 1-2 plug RF branching member 8112, and a first plug RF insertion groove 8113.

[0151] The 1-1 plug RF branching member 8111 is connected to the first receptacle RF connecting member 411. The 1-1 plug RF branching member 8111 can be coupled to the 1-1 receptacle RF branching member 4111 and connected to the first receptacle RF connecting member 411. The 1-1 plug RF branching member 8111 can be formed as a curved surface. As shown in Figures 19 and 20, the 1-1 plug RF branching member 8111 can be formed as a curved surface with respect to the second axial direction (Y-axis direction). Accordingly, the 1-1 plug RF branching member 8111 can move at least one of the first plug RF contact 81 and the first receptacle RF contact 41 with respect to the second axial direction (Y-axis direction). For example, if the first receptacle RF contact 41 is misaligned to the left with respect to the second axial direction (Y-axis direction) with reference to Figure 19, the first receptacle RF connecting member 411 will contact the 1-1 plug RF branching member 8111 and then move to the right along the curved surface formed by the 1-1 plug RF branching member 8111. Therefore, the substrate connector 1 according to the present invention can improve the ease of connecting the first receptacle RF contact 41 and the first plug RF contact 81 to each other.

[0152] The first-to-second plug RF branching member 8112 is connected to the first receptacle RF connecting member 411 at a position separated from the first-to-first plug RF branching member 8111. The first-to-second plug RF branching member 8112 can be coupled to the first receptacle RF branching member 4112 and connected to the first receptacle RF connecting member 411. The first-to-second plug RF branching member 8112 and the first-to-second plug RF branching member 8112 can be arranged to be separated from each other in the second axial direction (Y-axis direction). Accordingly, the substrate connector 1 according to the present invention can be implemented with a so-called double-contact structure in which the first receptacle RF contact 41 and the first plug RF contact 81 make contact at multiple different positions, thereby improving the connection reliability and contact stability for the first receptacle RF contact 41 and the first plug RF contact 81.

[0153] The first-to-second plug RF branching member 8112 can be formed as a curved surface. As shown in Figures 19 and 20, the first-to-second plug RF branching member 8112 can be formed as a curved surface with respect to the second axial direction (Y-axis direction). Accordingly, the first-to-second plug RF branching member 8112 can move at least one of the first plug RF contact 81 and the first receptacle RF contact 41 with respect to the second axial direction (Y-axis direction). For example, with respect to Figure 19, if the first receptacle RF contact 41 is misaligned to the right with respect to the second axial direction (Y-axis direction), the first receptacle RF connecting member 411 will move to the left along the curved surface formed by the first-to-second plug RF branching member 8112 after contacting the first-to-second plug RF branching member 8112. Therefore, the substrate connector 1 according to the present invention can improve the ease of connecting the first receptacle RF contact 41 and the first plug RF contact 81 to each other.

[0154] The first plug RF insertion groove 8113 is formed between the first-to-second plug RF branching member 8112 and the first-to-first plug RF branching member 8111. In this case, the connection between the first receptacle RF contact 41 and the first plug RF contact 81 can be made by inserting the first receptacle RF contact 41 into the first plug RF insertion groove 8113. In this case, the first receptacle RF contact 41 can function as a receptacle contact, and the first plug RF contact 81 can function as a plug contact. The first-to-second plug RF branching member 8112 and the first-to-first plug RF branching member 8111 are each formed with curved surfaces to guide the first receptacle RF connecting member 411 into the first plug RF insertion groove 8113. Although not shown in the figures, if the first plug RF insertion groove 8113 is formed in the first receptacle RF contact 41, the first receptacle RF contact 41 can function as a plug contact and the first plug RF contact 81 can function as a receptacle contact. The first-to-second plug RF branching member 8112 and the first-to-first plug RF branching member 8111 can each be formed to have a curved surface that is bent toward the first plug RF insertion groove 8113.

[0155] Referring to Figures 19 and 20, the first plug RF contact 81 may include the first plug RF mounting member 812.

[0156] The first plug RF mounting member 812 is intended to be mounted on the second substrate 10B. The first plug RF contact 81 is electrically connected to the second substrate 10B when the first plug RF mounting member 812 is mounted on the second substrate 10B. The first plug RF mounting member 812 may be made of a conductive material.

[0157] The first plug RF mounting member 812 is mounted on the second substrate 10B and connected to the first plug RF connecting member 811. In this case, the first plug RF mounting member 812 can be connected to the first-1 plug RF branching member 8111 and the first-2 plug RF branching member 8112, respectively, so that they move elastically. The first plug RF insertion groove 8113 can be located inside the first plug RF mounting member 812, the first-1 plug RF branching member 8111, and the first-2 plug RF branching member 8112. Therefore, the 1-2 plug RF branching member 8112 and the 1-1 plug RF branching member 8111 move outward away from the first plug RF mounting member 812 as the first receptacle RF connecting member 411 is pushed by the first receptacle RF connecting member 411 during the process in which the first receptacle RF connecting member 411 is inserted into the first plug RF insertion groove 8113. Once the first receptacle RF connecting member 411 is inserted into the first plug RF insertion groove 8113, the 1-2 plug RF branching member 8112 and the 1-1 plug RF branching member 8111 move inward towards the first plug RF mounting member 812 through a restoring force. Accordingly, when the first receptacle RF connection member 411 is inserted into the first plug RF insertion groove 8113, the first plug RF connection member 811 elastically pressurizes the first receptacle RF connection member 411, thereby firmly maintaining the connection between the first receptacle RF contact 41 and the first plug RF contact 81. In other words, the first-to-second plug RF branching member 8112 elastically pressurizes the first-to-second receptacle RF branching member 4112, and the first-to-first plug RF branching member 8111 elastically pressurizes the first-to-first receptacle RF branching member 4111, thereby firmly maintaining the connection between the first receptacle RF contact 41 and the first plug RF contact 81. The first plug RF mounting member 812, the first-to-first plug RF branching member 8111, and the first-to-second plug RF branching member 8112 may be formed integrally.

[0158] The second plug RF contact 82 may be coupled to the plug insulation portion 6 at a position separated from the first plug RF contact 81. The second plug RF contact 82 may be formed of a conductive material. The second plug RF contact 82 may be embodied substantially identically to the first plug RF contact 81, except for its position.

[0159] The second plug RF contact 82 is positioned to connect to the second receptacle RF contact 42, corresponding to the second receptacle RF contact 42. For the second plug RF contact 82 and the second receptacle RF contact 42 to connect to each other, the second receptacle RF contact 42 and the second plug RF contact 82 may each include the following configurations:

[0160] The second receptacle RF contact 42 includes a second receptacle RF connecting member.

[0161] The second receptacle RF connector is connected to the second plug RF contact 82 for electrical connection between the first substrate 10A and the second substrate 10B. The second receptacle RF contact 42 may be connected to the receptacle insulating portion 2 such that the second receptacle RF connector is coupled to the second RF projection 222. The second receptacle RF connector may be formed of a conductive material. The second receptacle RF connector may be formed in the shape of an inverted "U" as a whole. The second receptacle RF connector may be substantially identical to the first receptacle RF connector 411.

[0162] The second receptacle RF connecting member may include a second-first receptacle RF branching member, a second-second receptacle RF branching member, and a second receptacle RF connecting member. Since the second-first receptacle RF branching member, the second-second receptacle RF branching member, and the second receptacle RF connecting member are substantially identical to the first-first receptacle RF branching member 4111, the first-second receptacle RF branching member 4112, and the first receptacle RF connecting member 4113, a detailed explanation is omitted.

[0163] The second receptacle RF contact 42 may include a second receptacle RF mounting member.

[0164] The second receptacle RF mounting member is intended to be mounted on the first substrate 10A. Since the second receptacle RF mounting member is substantially identical to the first receptacle RF mounting member 412, a detailed explanation is omitted.

[0165] The second plug RF contact 82 may include a second plug RF connecting member.

[0166] The second plug RF connector is connected to the second receptacle RF connector for electrical connection between the first substrate 10A and the second substrate 10B. The second plug RF contact 82 may be coupled to the plug insulation 6 so that the second plug RF connector is housed in the second RF housing groove 622. The second plug RF connector may be formed of a conductive material. The second plug RF connector may be formed in the shape of an inverted "U" as a whole. The second plug RF connector may be substantially identical to the first plug RF connector 811.

[0167] The second plug RF connecting member may include a second-first plug RF branching member, a second-second plug RF branching member, and a second plug insertion groove. The second-first plug RF branching member, the second-second plug RF branching member, and the second plug insertion groove are substantially identical to the first-first plug RF branching member 8111, the first-second plug RF branching member 8112, and the first plug insertion groove 8113, respectively, so a detailed explanation is omitted.

[0168] The second plug RF contact 82 may include a second plug RF mounting member.

[0169] The second plug RF mounting member is intended to be mounted on the second substrate 10B. Since the second plug RF mounting member is substantially identical to the first plug RF mounting member 812, a detailed explanation is omitted.

[0170] Referring to Figures 5 and 14-16, the plug grounding portion 9 is for grounding to the receptacle grounding portion 5. The plug grounding portion 9 can be coupled to the plug insulating portion 6 so as to be separated from the plug RF contact 8.

[0171] The plug ground portion 9 may be formed to surround the side of the plug RF contact 8. Accordingly, the board connector 1 according to the present invention can embody a physical barrier that shields RF electromagnetic waves radiated from the plug RF contact 8 from flowing to the outside through the plug ground portion 9. Therefore, the board connector 1 according to the present invention can contribute to improving the performance of adjacent electronic devices. The housing grooves 61 and 62 may be located inside the plug ground portion 9. The plug ground portion 9 may extend from the lower surface of the plug insulating member 60 in the second direction (direction of the SD arrow). The plug ground portion 9 may be made of a metal material.

[0172] The plug ground portion 9 can be coupled with the receptacle ground portion 5 by being inserted into the mounting groove 23. When the plug ground portion 9 is inserted into the mounting groove 23, the plug RF contact 8 and the receptacle RF contact 4 can be housed inside the receptacle ground portion 5 and the plug ground portion 9. Accordingly, the PCB connector 1 according to the present invention can improve the shielding power of both the receptacle ground portion 5 and the plug ground portion 9 in shielding RF electromagnetic waves radiated from the RF contact portions 4 and 8, respectively. Accordingly, the PCB connector 1 according to the present invention can further contribute to improving the performance of adjacent electronic devices.

[0173] Referring to Figures 14 to 16, the plug grounding portion 9 may include the first plug grounding member 91.

[0174] The first plug grounding member 91 may be positioned at a distance from the first plug RF contact 81 and to shield at least two sides of the first plug RF contact 81. Accordingly, the substrate connector 1 according to the present invention can embody a shielding force that prevents RF electromagnetic waves radiated from the first plug RF contact 81 from flowing to the outside through the first plug grounding member 91.

[0175] The first plug grounding member 91 may be formed at a position spaced apart from the first plug RF contact 81 and to shield the first plug RF contact 81 on all sides. In this case, the first plug RF contact 81 can be located inside the first plug grounding member 91. Accordingly, the substrate connector 1 according to the present invention can enhance the shielding force using the first plug grounding member 91. The first plug grounding member 91 may be formed at a position spaced apart from the first plug RF contact 81 and to shield the first plug RF contact 81 on all four sides.

[0176] Referring to Figures 15, 16, and 21, a plug cutting hole 8a can be formed between the first plug grounding member 91 and the first plug RF contact 81. The first plug grounding member 91 and the first plug RF contact 81 can be separated from each other with respect to the plug cutting hole 8a. If the first plug grounding member 91 and the first plug RF contact 81 are integrally formed through a single sheet material, the plug cutting hole 8a can be formed in a single pressing operation. Accordingly, the PCB connector 1 according to the present invention can improve the ease of manufacturing of the first plug grounding member 91 and the first plug RF contact 81, and can reduce the possibility of the first plug grounding member 91 and the first plug RF contact 81 being grounded to each other through the plug cutting hole 8a. Therefore, the PCB connector 1 according to the present invention can improve the performance of the first plug grounding member 91 and the first plug RF contact 81.

[0177] The plug cutting holes 8a may be formed in the same number as the RF contacts belonging to the plug RF contact 8. If the plug RF contact 8 includes two RF contacts 81 and 82, the board connector 1 according to the present invention may include two plug cutting holes 8a. Figure 15 illustrates two of the plug cutting holes 8a, but this is illustrative, and the board connector 1 according to the present invention may include one plug cutting hole 8a or three or more plug cutting holes 8a, as long as the plug RF contact 8 and the plug ground portion 9 can be separated.

[0178] The plug cutting hole 8a may communicate with a plug communication hole (not shown) formed in the plug insulation portion 6. The plug communication hole may be formed to be larger than the plug cutting hole 8a. The plug communication hole may be formed in the form of a rectangular parallelepiped as a whole. The plug communication hole may be positioned on the second direction (SD arrow direction) side relative to the plug cutting hole 8a. The plug communication hole and the plug cutting hole 8a may be formed together through a single press process.

[0179] Referring to Figures 15, 16, and 21, the first plug grounding member 91 may include the first plug grounding mounting member 911.

[0180] The first plug grounding mounting member 911 is mounted on the second substrate 10B. The first plug grounding member 911 can be mounted on the second substrate 10B through the first plug grounding mounting member 911. The first plug grounding mounting member 911 can protrude toward the first plug RF mounting member 812.
