Description

Technical Field

[0001] The present disclosure relates to the field of radio frequency technology, and in particular to a radio frequency integrated socket, a printed circuit board, and a terminal device. Background Art

[0002] The coaxial cables used in current terminal devices, such as mobile phones, are primarily used for relaying RF signals over long distances. For example, they transmit the RF signal from the antenna at the bottom of the phone to the printed circuit board (PCB) inside the phone. After soldering a coaxial connector to the PCB, the connectors on the cable are used to snap one end of the cable to the coaxial connector on the small board at the bottom of the phone, and the other end to the coaxial connector on the PCB. This allows the antenna RF signal to be transmitted from the bottom of the phone to the coaxial connector on the PCB. Additionally, an RF test connector is typically placed immediately after the coaxial connector on the PCB. This connector is used to test RF signals during trial and mass production.

[0003] However, the RF test socket is only used for RF testing and has no actual function. As the number of antennas in mobile phones increases, the number of RF test sockets also increases, resulting in the RF test sockets occupying a larger design space on the printed circuit board, greatly affecting the integration of the printed circuit board and hindering the optimized design of devices and circuits on the printed circuit board.

[0035] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features therein can be combined with each other in the absence of conflict.

[0036] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0037] Figure 1 This is a schematic side view of a radio frequency integrated socket provided by an embodiment of the present disclosure. Figure 2 This is a side view of a radio frequency integrated plug provided by an embodiment of the present disclosure. Figure 1 and Figure 2 The radio frequency integrated socket includes a coaxial seat stop 1, a radio frequency test seat stop 2 and an elastic component 3.

[0038] The coaxial seat stop 1 and the RF test seat stop 2 are arranged along the direction in which the RF integrated socket is inserted into the RF integrated plug 11. Figure 1 The RF integrated plug 11 is inserted downward into the RF integrated socket, so the coaxial seat stop 1 is set at Figure 1Above the middle RF test socket gear 2. A concave structure 4 is provided on the side of the elastic component 3 that is away from the direction in which the RF integrated socket is inserted into the RF integrated plug 11. The concave structure 4 is recessed in the direction in which the RF integrated socket is inserted into the RF integrated plug 11, that is, a concave structure 4 is provided above the elastic component 3. When the RF integrated plug 11 is inserted downward into the RF integrated socket, the concave structure 4 is recessed downward. The concave structure 4 is electrically connected to the RF signal pad 5 on the RF integrated socket through the elastic component 3, that is, the concave structure 4 is electrically connected to the RF signal pad 5 on the RF integrated socket. The concave structure 4 and the elastic component 3 are used to transmit RF signals.

[0039] The coaxial cables used in current terminal devices, such as mobile phones, are mainly used for relaying radio frequency signals over long distances. For example, the radio frequency signal of the antenna at the bottom of the mobile phone is transmitted to the printed circuit board in the mobile phone, such as the main board. After the coaxial socket is soldered on the printed circuit board, one end of the cable is fastened to the coaxial socket on the small board at the bottom of the mobile phone, and the other end is fastened to the coaxial socket on the printed circuit board through the connector on the cable. The cable is used to realize the transmission of the antenna radio frequency signal between the bottom of the mobile phone and the coaxial socket on the printed circuit board. Usually, an RF test socket needs to be set up immediately after the coaxial socket. The RF test socket is used for testing radio frequency signals in the trial production and mass production stages. However, the RF test socket is only for testing and has no actual function. Moreover, as the number of antennas in the mobile phone increases, the number of RF test sockets also increases, resulting in the RF test socket occupying a large design space on the printed circuit board.

[0040] Figure 3 This is a side view of a radio frequency integrated socket provided by an embodiment of the present disclosure to realize the coaxial seat function. Figure 4 A schematic diagram of the side structure of a radio frequency integrated socket provided by the embodiment of the present disclosure to realize the function of a radio frequency test socket. Figures 1 to 4 When the elastic component 3 is compressed to the coaxial seat position 1, the contact area between the RF integrated plug 11 and the concave structure 4 is smaller than the contact area between the elastic component 3 and the RF test seat position 2.

[0041] Specifically, a concave structure 4 is provided on top of the elastic component 3. When the RF integrated plug 11 is inserted into the coaxial seat stop 1, the RF integrated plug 11 contacts the concave structure 4 and compresses part of the elastic component 3 through the concave structure 4. The RF integrated plug 11 contacts a portion of the concave structure 4 to realize the coaxial seat function. When the RF integrated plug 11 is inserted into the RF test seat stop 2, the RF integrated plug 11 contacts the concave structure 4 and compresses all of the elastic component 3 through the concave structure 4. The RF integrated plug 11 contacts the entire area of the concave structure 4 facing the RF integrated plug 11 to realize the RF test seat function.

[0042] For example, in combination Figure 3 and Figure 4 When the RF integrated plug 11 is inserted into the coaxial seat gear 1, the RF integrated plug 11 can be set to only partially contact the concave structure 4. When the RF integrated plug 11 is inserted into the RF test seat gear 2, the elastic component 3 is completely compressed, and the concave structure 4 will also sink. The concave structure 4 is deformed, that is, the side of the concave structure 4 shrinks inward, and the RF integrated plug 11 is fully in contact with the concave structure 4, and the contact area between the RF integrated plug 11 and the concave structure 4 increases.

[0043] Compared to the coaxial socket, the RF test socket corresponds to a higher frequency band of RF signals, and the corresponding voltage standing wave ratio of the RF test socket is more finely divided into different frequency bands. The elastic component 3 is compressed to the RF test socket position 2, and the contact area between the RF integrated plug 11 and the concave structure 4 is larger, which can achieve the transmission of RF signals in higher frequency bands and optimize the transmission performance of RF signals. It can also achieve a more finely divided voltage standing wave ratio corresponding to different frequency bands, thereby realizing the function of the RF test socket. The elastic component 3 is compressed to the coaxial socket position 1, and the contact area between the RF integrated plug 11 and the concave structure 4 is smaller, which can achieve the transmission of RF signals in lower frequency bands. The coaxial socket has lower requirements for the RF signal frequency band, thereby realizing the function of the coaxial socket.

[0044] The embodiment of the present disclosure realizes a pluggable RF integrated socket by setting the elastic component 3 to be compressed to the coaxial seat stop 1, and the contact area between the RF integrated plug 11 and the concave structure 4 is smaller than the contact area between the RF integrated plug 11 and the concave structure 4 when the elastic component 3 is compressed to the RF test seat stop 2, which can firmly fix the RF integrated plug 11. The RF integrated socket is compatible with the functions of the coaxial seat and the RF test seat, which is beneficial to greatly save the use area of the RF test seat on the design side, reduce the area occupied by the RF test seat on the printed circuit board, improve the integration of the printed circuit board, and is beneficial to the optimized design of devices and circuits on the printed circuit board. For example, the printed circuit board can provide more space for the battery design of the terminal device, which is beneficial to improve the battery capacity of the terminal device. At the same time, the RF trace that needs to connect the coaxial seat and the RF test seat can realize the electrical connection between the two without passing through two solder pads, thereby shortening the length of the RF trace, which is beneficial to reducing the impedance change of the RF trace, so as to optimize the RF trace and improve the performance of the RF trace.

[0045] Optionally, combined Figures 1 to 4The concave structure 4 can be provided with a transverse structure 41 and an annular warping structure 42. The transverse structure 41 is fixedly connected to the elastic component 3. The transverse structure 41 is arranged perpendicular to the direction in which the RF integrated socket is inserted into the RF integrated plug 11. The annular warping structure 42 is arranged around the transverse structure 41. The annular warping structure 42 is contracted along the direction in which the RF integrated socket is inserted into the RF integrated plug 11, that is, the annular warping structure 42 is warped along the direction in which the RF integrated socket is inserted into the RF integrated plug 11.

[0046] Specifically, the concave structure 4 is formed by the horizontal structure 41 and the annular warping structure 42. Figure 1 In the structure shown, the RF integrated plug 11 is inserted downward into the RF integrated socket, and the concave structure 4 is recessed in the direction in which the RF integrated socket inserts the RF integrated plug 11, that is, the concave structure 4 is recessed downward. When the RF integrated plug 11 is inserted into the coaxial seat stop 1, the elastic component 3 is partially compressed, and the RF integrated plug 11 can be set to contact only the transverse structure 41 of the concave structure 4; when the RF integrated plug 11 is inserted into the RF test seat stop 2, the elastic component 3 is fully compressed, and the transverse structure 41 of the concave structure 4 also sinks, and the annular warping structure 42 of the concave structure 4 contracts inward. The RF integrated plug 11 contacts both the transverse structure 41 and the annular warping structure 42 of the concave structure 4, and the contact area between the RF integrated plug 11 and the concave structure 4 is increased. In this way, when the elastic component 3 is compressed to the coaxial seat position 1, the contact area between the RF integrated plug 11 and the concave structure 4 is smaller than the contact area between the RF integrated plug 11 and the concave structure 4 when the elastic component 3 is compressed to the RF test seat position 2, thereby realizing a pluggable RF integrated socket, which is compatible with the functions of the coaxial seat and the RF test seat.

[0047] Optionally, combined Figures 1 to 4 , the concave structure 4 can be set to have an inverted trapezoidal cross-section along the direction in which the RF integrated socket is inserted into the RF integrated plug 11, so as to be concave in the direction in which the RF integrated socket is inserted into the RF integrated plug 11, thereby achieving the elastic component 3 being compressed to the coaxial seat stop 1, and the contact area between the RF integrated plug 11 and the concave structure 4 being smaller than the contact area between the RF integrated plug 11 and the concave structure 4 when the elastic component 3 is compressed to the RF test seat stop 2. It should be noted that the embodiment of the present disclosure only exemplarily sets the concave structure 4 to have an inverted trapezoidal cross-section along the direction in which the RF integrated socket is inserted into the RF integrated plug 11, and the embodiment of the present disclosure does not make any specific limitation on this, and it is sufficient to ensure that the elastic component 3 is compressed to the coaxial seat stop 1, and the contact area between the RF integrated plug 11 and the concave structure 4 is smaller than the contact area between the elastic component 3 and the RF integrated plug 11 and the concave structure 4 when the elastic component 3 is compressed to the RF test seat stop 2.

[0048] For example, the concave structure 4 may be arranged to be in an arc-shaped recessed shape, and correspondingly, the lower end of the RF integrated plug 11 may also be arranged to be in an arc-shaped convex shape. When the RF integrated plug 11 is inserted into the coaxial seat stop 1, the RF integrated plug 11 contacts the concave structure 4 in an arc-shaped recessed shape and partially compresses the elastic component 3 through the concave structure 4. The RF integrated plug 11 contacts a portion of the area of the concave structure 4 in an arc-shaped recessed shape to realize the coaxial seat function. When the RF integrated plug 11 is inserted into the RF test seat gear position 2, the RF integrated plug 11 contacts the concave structure 4 with a circular arc shape and compresses all the elastic components 3 through the concave structure 4. The RF integrated plug 11 contacts the entire area of the concave structure 4 with a circular arc shape facing the RF integrated plug 11 to realize the RF test seat function. Similarly, the elastic component 3 can be compressed to the coaxial seat gear position 1. The contact area between the RF integrated plug 11 and the concave structure 4 is smaller than the contact area between the RF integrated plug 11 and the concave structure 4 when the elastic component 3 is compressed to the RF test seat gear position 2.

[0049] Optionally, combined Figures 1 to 4 The RF integrated socket may further include a bottom structure 6 and an opening structure 7, wherein the opening structure 7 and the bottom structure 6 are arranged along the direction in which the RF integrated socket is inserted into the RF integrated plug 11. The coaxial seat stop 1 is arranged on the side of the RF test seat stop 2 adjacent to the opening structure 7, the RF signal pad 5 is arranged on the bottom structure 6, one end of the elastic component 3 is fixed and electrically connected to the RF signal pad 5, and the other end of the elastic component 3 is fixedly connected to the concave structure 4. Specifically, the opening structure 7 is used to insert the RF integrated plug 11, that is, the RF integrated plug 11 is inserted into the RF integrated socket through the opening structure 7, the opening structure 7 is located on the upper part of the bottom structure 6, and the coaxial seat stop 1 is arranged on the side of the RF test seat stop 2 adjacent to the opening structure 7, that is, the coaxial seat stop 1 is arranged above the RF test seat stop 2.

[0050] Exemplarily, the elastic component 3 can be a metal spring, the RF signal pad 5 is arranged on the bottom structure 6, one end of the elastic component 3 is fixed and electrically connected to the RF signal pad 5, and the other end of the elastic component 3 is fixedly connected to the concave structure 4, that is, the metal spring at the center position of the RF integrated socket is electrically connected to the RF signal pad 5 on the RF integrated socket, transmitting the RF signal to the concave structure 4, and then when the RF integrated plug 11 is inserted into the RF integrated socket, the transmission of the RF signal from the RF integrated socket to the RF integrated plug 11 is realized.

[0051] Optionally, combined Figures 1 to 4The RF integrated socket may further include a side wall structure 8, which forms a space where the RF integrated socket is located with the side wall structure 8 and the bottom structure 6. The inner wall of the side wall structure 8 is provided with two snap spring groups 9 along the direction in which the RF integrated socket is inserted into the RF integrated plug 11. The snap spring group 9 adjacent to the opening structure 7 is used to fix the RF integrated plug 11 at the coaxial seat gear position 1, and the snap spring group 9 adjacent to the bottom structure 6 is used to fix the socket at the RF test seat gear position 2.

[0052] Specifically, the side wall structure 8 can be set to a cylindrical structure, and the bottom structure 6 can be, for example, a circular structure. The cylindrical side wall structure 8 and the circular bottom structure 6 surround and form a space where the RF integrated socket is located. For another example, the side wall structure 8 can be set to a cubic columnar structure, and the bottom structure 6 can be, for example, a rectangular structure. The cubic columnar side wall structure 8 and the rectangular bottom structure 6 surround and form a space where the RF integrated socket is located. It should be noted that the side wall structure 8 and the bottom structure 6 can also be set to other shapes. This is not specifically limited in the embodiments of the present disclosure. It is sufficient to ensure that the side wall structure 8 and the bottom structure 6 can surround and form a space where the RF integrated socket is located.

[0053] Two layers of snap-on spring groups 9 are provided on the side wall structure 8 to realize two-stage plugging and unplugging of the RF integrated plug 11 relative to the RF integrated socket, thereby realizing a pluggable RF integrated socket. The RF integrated socket is compatible with the functions of the coaxial socket and the RF test socket.

[0054] For example, Figure 2 As shown, a slot structure 12 can be provided on the radio frequency integrated plug 11 corresponding to the radio frequency integrated socket. Figures 1 to 4 , the snap spring piece 91 on the side wall structure 8 of the RF integrated socket is set to correspond to the shape of the card slot structure 12 on the RF integrated plug 11. For example, the snap spring piece 91 is set to have a protruding structure corresponding to the shape of the card slot structure 12 on the RF integrated plug 11. When the RF integrated plug 11 is inserted into the coaxial seat gear 1, the snap spring piece group 9 adjacent to the opening structure 7 is used to fix the RF integrated plug 11 at the coaxial seat gear 1; when the RF integrated plug 11 is inserted into the RF test seat gear 2, the snap spring piece group 9 adjacent to the bottom structure 6 is used to fix the socket at the RF test seat gear 2, thereby realizing a pluggable RF integrated socket, and the RF integrated socket is compatible with the functions of the coaxial seat and the RF test seat. It should be noted that, Figure 4 As shown, when the RF integrated plug 11 is inserted into the RF test socket position 2, the snap spring group 9 adjacent to the bottom structure 6 is used to fix the socket at the RF test socket position 2. At this time, the snap spring corresponding to the coaxial seat position 1 will be pushed out of the columnar structure of the RF integrated plug 11.

[0055] It should be noted that the embodiment of the present disclosure only takes the example of a card slot structure 12 being provided on the RF integrated plug 11, and the card snap spring 91 having a protruding structure corresponding to the shape of the card slot structure 12 on the RF integrated plug 11. The embodiment of the present disclosure does not specifically limit this. It is sufficient to ensure that the card snap spring group 9 adjacent to the opening structure 7 can fix the RF integrated plug 11 at the coaxial seat gear 1, and the card snap spring group 9 adjacent to the bottom structure 6 can fix the socket at the RF test seat gear 2. For example, the RF integrated plug 11 can also be provided with a protruding structure, and the card snap spring 91 has a card slot structure corresponding to the shape of the protruding structure on the RF integrated plug 11.

[0056] Optionally, combined Figures 1 to 4 , the snap spring group 9 can be set to include at least two independent snap springs, at least two independent snap springs are evenly distributed on the inner wall of the side wall structure 8, and at least two independent snap springs are located in a plane parallel to the bottom structure 6, that is, each snap spring group 9 can be set to include multiple independently set snap springs. When the RF integrated plug 11 is inserted into the corresponding gear position, each independent snap spring in the corresponding snap spring group 9 is matched in shape with the corresponding fixing structure on the RF integrated plug 11, thereby fixing the RF integrated plug 11 in the corresponding gear position. Exemplarily, for example, the snap spring group 9 can be set to include four independent snap springs, and the four independent snap springs are evenly distributed on the inner wall of the side wall structure 8, that is, along the plane parallel to the bottom structure 6, the angle between two adjacent snap springs is 90°, and the four independent snap springs are located in a plane parallel to the bottom structure 6.

[0057] Optionally, combined Figures 1 to 4 , the snap spring group 9 can also be provided with an annular snap spring, the annular snap spring is provided on the inner wall of the side wall structure 8, and the plane on which the annular snap spring is located is parallel to the bottom structure 6, that is, each snap spring group 9 can be provided with an annular snap spring. When the RF integrated plug 11 is inserted into the corresponding gear position, the annular snap spring and the corresponding fixing structure on the RF integrated plug 11 are matched in shape, thereby fixing the RF integrated plug 11 in the corresponding gear position.

[0058] Figure 5 This is a schematic diagram of a top view of the bottom structure of a radio frequency integrated socket provided by an embodiment of the present disclosure. Figures 1 to 5In addition to the RF signal pad 5 provided at the center of the bottom structure 6 to connect the elastic component 3 to provide the RF signal to the concave structure 4, the bottom structure 6 can also be provided with at least one ground pad 10. The sidewall structure 8 is electrically connected to the at least one ground pad 10 to form a metal shielding structure. Specifically, the bottom structure 6 includes a portion made of insulating material and a portion made of conductive metal. The pad is the conductive metal, and all parts of the bottom structure 6 except the pad are made of insulating material. For example, a plurality of ground pads 10 can be provided on the bottom structure 6, for example Figure 5 By way of example, three ground pads 10 are provided on the bottom structure 6. For example, if the bottom structure 6 is rectangular, three ground pads 10 can be provided on the three sides of the rectangle. It should be noted that the present disclosure does not limit the specific number or location of the ground pads 10 on the bottom structure 6; it is sufficient to ensure that the sidewall structure 8 is electrically connected to at least one ground pad 10.

[0059] A sidewall structure 8 is electrically connected to at least one ground pad 10 to form a metal shielding structure. The sidewall structure 8 is a metal structure. While the sidewall structure 8 forms a space for the RF integrated socket with the bottom structure 6, the sidewall structure 8 is electrically connected to at least one ground pad 10 on the bottom structure 6. The ground signal is transmitted on the sidewall structure 8 to form a shielding structure to prevent signals outside the RF integrated socket from interfering with the transmission process of the RF signal of the RF integrated socket.

[0060] Figure 6 This is a schematic diagram of the gear connection of a radio frequency integrated socket provided by an embodiment of the present disclosure. Figures 1 to 6 , Figure 6 The leftmost figure illustrates the structure of RF integrated socket 13 before plugging into RF integrated plug 11. The middle figure illustrates the structure after RF integrated plug 11 is inserted into coaxial socket position 1. The rightmost figure illustrates the structure after RF integrated plug 11 is inserted into RF test socket position 2. The upper part shows RF integrated plug 11, and the lower part shows RF integrated socket 13. G indicates that the terminal is grounded, and S indicates that the terminal is connected to the RF signal.

[0061] Optionally, combined Figures 1 to 6 The characteristic impedance of the elastic component 3 can be set to be greater than or equal to 47.5 ohms and less than or equal to 52.5 ohms. Preferably, the characteristic impedance of the elastic component 3 can be set to be equal to 50 ohms. Setting the characteristic impedance of the elastic component 3 to be greater than or equal to 47.5 ohms and less than or equal to 52.5 ohms is beneficial to improving the impedance consistency between the elastic component 3 and the coaxial cable or coaxial seat, avoiding the problem of reflection of the RF signal caused by impedance mutation, and optimizing the transmission effect of the RF signal.

[0062] The present disclosure also provides a radio frequency integrated plug. Figures 1 to 6 The RF integrated plug 11 includes a columnar structure 14. A convex structure 15 is provided on one side of the columnar structure 14 along the direction in which the RF integrated plug 11 is inserted into the RF integrated socket 13. The convex structure 15 protrudes in the direction in which the RF integrated plug 11 is inserted into the RF integrated socket 13. The convex structure 15 is electrically connected to the RF signal pad 5 on the RF integrated socket 13 through the concave structure 4 in the RF integrated socket 13. The convex structure 15 is located at the coaxial seat stop 1. The contact area between the convex structure 15 and the concave structure 4 is smaller than the contact area between the convex structure 15 and the concave structure 4 when the convex structure 15 is located at the RF test seat stop 2.

[0063] Optionally, combined Figures 1 to 6 The convex structure 15 may include a first transverse structure 151 and a first annular warped structure 152. The first transverse structure 151 is located on one side of the first annular warped structure 152 along the direction in which the RF integrated plug 11 is inserted into the RF integrated socket 13. The first transverse structure 151 is arranged perpendicular to the direction in which the RF integrated plug 11 is inserted into the RF integrated socket 13. The first annular warped structure 152 is arranged around the first transverse structure 151 and is arranged to contract along the direction in which the RF integrated plug 11 is inserted into the RF integrated socket 13. For example, the cross-section of the convex structure 15 along the direction in which the RF integrated plug 11 is inserted into the RF integrated socket 13 may be an inverted trapezoid.

[0064] Optionally, combined Figures 1 to 6 After the RF integrated plug 11 is inserted into the RF integrated socket 13, the first sidewall structure 17 and the top structure 16 are both electrically connected to the at least one ground pad 10 on the RF integrated socket 13 to form a metal shielding structure. Specifically, after the RF integrated plug 11 is inserted into the RF integrated socket 13, the first sidewall structure 17 and the top structure 16 are both in contact with the first sidewall structure 8 of the RF integrated socket 13, thereby achieving electrical connection between the first sidewall structure 17 and the top structure 16 and the at least one ground pad 10 on the RF integrated socket 13 to form a metal shielding structure, thereby preventing signals outside the RF integrated plug 11 from interfering with the transmission process of the RF signal of the RF integrated plug 11.

[0065] Optionally, combined Figures 1 to 6 The material constituting the convex structure 15 may include copper, and the convex surface of the convex structure 15 may be covered with a passivation metal layer. Preferably, the material constituting the passivation metal layer may include gold. For example, the surface of the convex structure 15 corresponding to the first horizontal structure 151 and the outer surface corresponding to the first annular warping structure 152 may be covered with a passivation metal layer.

[0066] Specifically, the columnar structure 14 is formed by coating the entire copper column with an insulating material. The copper column itself is very suitable for transmitting RF signals. The copper at the lower end of the copper column, which contacts the RF integrated socket 13, is exposed and gold-plated. The exposed copper at the lower end of the copper column is used to connect to the RF signal on the RF integrated socket 13. In addition, the gold plating at the contact point between the lower end of the copper column and the RF integrated socket 13 can effectively prevent oxidation of the contact point, further reducing the contact impedance between the RF integrated plug 11 and the RF integrated socket 13.

[0067] Optionally, combined Figures 1 to 6 The columnar structure 14 can be set to be fixed and insulated from the top structure 16 at one end away from the convex structure 15. The columnar structure 14 is formed by coating an insulating material around a copper column. The copper column is used to transmit radio frequency signals, and the top structure 16 transmits ground signals. Therefore, the columnar structure 14 needs to be insulated from the top structure 16 at one end away from the convex structure 15.

[0068] Optionally, the columnar structure 14 may include a copper column and an insulating material covering a portion of the copper column, wherein the characteristic impedance of the copper column is greater than or equal to 47.5 ohms and less than or equal to 52.5 ohms. Preferably, the characteristic impedance of the copper column may be set to 50 ohms. Setting the characteristic impedance of the copper column to be greater than or equal to 47.5 ohms and less than or equal to 52.5 ohms is beneficial for improving the impedance consistency of the copper column, the elastic component 3, and the coaxial line or the coaxial seat, avoiding problems such as reflection of the RF signal caused by impedance mutation, and optimizing the transmission effect of the RF signal.

[0069] In this way, a physically pluggable RF integrated plug is realized, and the RF integrated plug is suitable for an RF integrated socket that is compatible with a coaxial socket and an RF test socket. The coaxial socket function of the RF integrated socket can be realized by inserting the RF integrated plug into the RF integrated socket, and the RF test socket function of the RF integrated socket can also be realized by inserting the RF integrated plug into the RF integrated socket. This provides the possibility for realizing an RF integrated socket that is compatible with the coaxial socket and RF test socket functions, which is beneficial to greatly save the use area of the RF test socket on the design end, thereby reducing the area occupied by the RF test socket on the printed circuit board and improving the integration of the printed circuit board.
