Description

Technical Field

[0001] The present disclosure relates to the field of radio frequency technology, and in particular to a radio frequency integrated plug and connector. Background Art

[0002] The coaxial cables used in current terminal devices, such as mobile phones, are mainly used for relay transmission of long-distance RF signals. For example, the RF signal of the antenna at the bottom of the mobile phone is transmitted to the printed circuit board in the mobile phone. After the coaxial seat is soldered on the printed circuit board, one end of the cable is respectively fastened to the coaxial seat on the small board at the bottom of the mobile phone, and the other end is fastened to the coaxial seat on the printed circuit board through the connector on the cable. The cable is used to realize the transmission of the antenna RF signal between the bottom of the mobile phone and the coaxial seat on the printed circuit board. In addition, an RF test seat is usually required to be set up immediately after the coaxial seat on the printed circuit board. The RF test seat is used to test the RF signal during the trial production and mass production stages.

As the number of antennas in mobile phones increases, the number of RF test sockets also increases, resulting in the RF test socket occupying a larger design space on the printed circuit board, which greatly affects the integration of the printed circuit board and is not conducive to the optimized design of devices and circuits on the printed circuit board.

[0034] 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 in the embodiments can be combined with each other without conflict.

[0035] 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.

[0036] Figure 1 A schematic diagram of the side structure of a radio frequency integrated plug provided in an embodiment of the present disclosure is shown in FIG. Figure 2 A schematic diagram of the side structure of a radio frequency integrated socket provided by an embodiment of the present disclosure. Figure 1 and Figure 2The 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 RF integrated plug 11 is inserted downward into the RF integrated socket 13, and the convex structure 15 protrudes downward. 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.

[0037] Specifically, combined Figure 1 and Figure 2 , the RF integrated socket 13 can be provided to include a coaxial seat stop 1, a RF test seat stop 2 and an elastic component 3. The coaxial seat stop 1 and the RF test seat stop 2 are arranged along the direction in which the RF integrated socket 13 is inserted into the RF integrated plug 11, and the RF integrated socket 13 is provided to be ... Figure 1 and Figure 2 , the RF integrated plug 11 is inserted downward into the RF integrated socket 13, so the coaxial seat stop 1 is set at Figure 2 Above the middle RF test seat gear 2. A concave structure 4 is provided on the side of the elastic component 3 away from the direction in which the RF integrated socket 13 is inserted into the RF integrated plug 11, and the concave structure 4 is recessed in the direction in which the RF integrated socket 13 is inserted into the RF integrated plug 11, that is, a concave structure 4 is provided above the elastic component 3, and the RF integrated plug 11 is inserted downward into the RF integrated socket 13, and the concave structure 4 is recessed downward, and the concave structure 4 is electrically connected to the RF signal pad 5 on the RF integrated socket 13 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 13, and the concave structure 4 and the elastic component 3 are used to transmit RF signals.

[0038] The coaxial lines used in current terminal devices, such as mobile phones, are mainly used for relay transmission of long-distance radio frequency signals, such as transmitting the antenna radio frequency signal of the lower part of the mobile phone to the printed circuit board in the mobile phone, such as the main board. After the coaxial seat is welded on the printed circuit board, one end of the cable is respectively fastened to the coaxial seat on the small board of the lower part of the mobile phone, and the other end is connected to the coaxial seat on the printed circuit board through the connector on the cable. The antenna radio frequency signal transmission between the lower part of the mobile phone and the coaxial seat on the printed circuit board is realized by using the cable. Usually, an RF test seat needs to be set immediately after the coaxial seat. The RF test seat is used for testing RF signals in the trial production and mass production stages. However, the RF test seat is only for testing and has no actual function. As the number of antennas in the mobile phone increases, the number of RF test seats also increases, resulting in the RF test seat occupying a large design space on the printed circuit board. Therefore, how to realize the integration of the coaxial seat and the RF test seat becomes the key to solving the previous problem. The structure of the coaxial seat and the RF test seat is different, and the structure of the plugs matched to each other is also different. Plugs with different structures further increase the difficulty of integrating the coaxial seat with the RF test seat.

[0039] Figure 3 A schematic diagram of the side structure of a radio frequency integrated socket realizing the coaxial socket function provided by an embodiment of the present disclosure, 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. Figure 3 and Figure 4 The convex structure 15 is located at the coaxial seat stop 1, that is, the elastic component 3 is compressed to the coaxial seat stop 1, and 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, that is, the elastic component 3 is compressed to the RF test seat stop 2.

[0040] Specifically, 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, and a concave structure 4 is provided on the top of the elastic component 3. When the RF integrated plug 11 is inserted into the coaxial seat position 1, the convex structure 15 contacts the concave structure 4 and compresses part of the elastic component 3 through the concave structure 4, and the convex structure 15 contacts part of the area of ​​the concave structure 4, so that the RF integrated socket 13 realizes the coaxial seat function. When the RF integrated plug 11 is inserted into the RF test socket position 2, the convex structure 15 contacts the concave structure 4 and compresses all the elastic components 3 through the concave structure 4, and the convex structure 15 contacts the entire area of ​​the concave structure 4 facing the RF integrated plug 11, so that the RF integrated socket 13 realizes the RF test socket function.

[0041] For example, in combination Figure 3 and Figure 4When the RF integrated plug 11 is inserted into the coaxial seat position 1, the convex structure 15 can be set to only partially contact the concave structure 4. When the RF integrated plug 11 is inserted into the RF test seat position 2, the elastic component 3 is completely compressed, and the concave structure 4 will also sink accordingly, and the concave structure 4 will deform, that is, the side of the concave structure 4 will shrink inward, and the convex structure 15 will be completely in contact with the concave structure 4, and the contact area between the convex structure 15 and the concave structure 4 will increase.

[0042] Compared with the coaxial seat, the RF test seat corresponds to a higher frequency band of the RF signal, and the voltage standing wave ratio corresponding to the RF test seat is more finely divided into different frequency bands. The elastic component 3 is compressed to the RF test seat position 2, and the contact area between the convex structure 15 and the concave structure 4 is larger, which can realize the transmission of RF signals in higher frequency bands, and optimize the transmission performance of RF signals, and can realize a more finely divided voltage standing wave ratio corresponding to different frequency bands, thereby realizing the function of the RF test seat. The elastic component 3 is compressed to the coaxial seat position 1, and the contact area between the convex structure 15 and the concave structure 4 is smaller, which can realize the transmission of RF signals in lower frequency bands, and the coaxial seat has lower requirements on the frequency band of RF signals, thereby realizing the function of the coaxial seat.

[0043] The embodiment of the present disclosure realizes a physically pluggable RF integrated plug by arranging the convex structure 15 at the coaxial seat stop 1, and 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 at the RF test seat stop 2, so that the RF integrated plug can be firmly fixed in the RF integrated socket, and the RF integrated plug is suitable for the RF integrated socket compatible with the coaxial seat and the RF test seat, and the coaxial seat function of the RF integrated socket can be realized by inserting the RF integrated plug into the RF integrated socket, and the RF test seat function of the RF integrated socket can also be realized by inserting the RF integrated plug into the RF integrated socket, which provides the possibility for realizing the RF integrated socket compatible with the coaxial seat and the RF test seat function, is beneficial to greatly save the use area of ​​the RF test seat at the design end, reduces the area occupied by the RF test seat on the printed circuit board, improves 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 achieve electrical connection between the two without passing through two 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.

[0044] Optionally, combined Figures 1 to 4The convex structure 15 may include a transverse structure 151 and an annular warping structure 152. The transverse structure 151 is located on one side of the annular warping structure 152 along the direction in which the RF integrated plug 11 is inserted into the RF integrated socket 13. The 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 annular warping structure 152 is arranged around the transverse structure 151. The annular warping structure 152 is arranged to shrink along the direction in which the RF integrated plug 11 is inserted into the RF integrated socket 13.

[0045] Specifically, the concave structure 4 of the RF integrated socket 13 can also be set to include a first transverse structure 41 and a first annular warping structure 42, the first transverse structure 41 is fixedly connected to the elastic component 3, the first transverse structure 41 is arranged perpendicular to the direction in which the RF integrated socket 13 is inserted into the RF integrated plug 11, the first annular warping structure 42 is arranged around the first transverse structure 41, and the first annular warping structure 42 is contracted along the direction in which the RF integrated socket 13 is inserted into the RF integrated plug 11, that is, the first annular warping structure 42 is warped along the direction in which the RF integrated socket 13 is inserted into the RF integrated plug 11.

[0046] Specifically, the convex structure 15 is formed by using the horizontal structure 151 and the annular warping structure 152. Figure 1 In the structure shown in the figure, the RF integrated plug 11 is inserted downward into the RF integrated socket 13, and the convex structure 15 is convex in the direction in which the RF integrated plug 11 is inserted into the RF integrated socket 13, that is, the convex structure 15 is convex downward. Figure 2 In the structure shown, the RF integrated plug 11 is inserted downward into the RF integrated socket 13, and the concave structure 4 is recessed in the direction of the RF integrated socket 13 inserting the RF integrated plug 11, that is, the concave structure 4 is recessed downward. Figures 1 to 4When the RF integrated plug 11 is inserted into the coaxial seat gear position 1, the elastic component 3 is partially compressed, and the transverse structure 151 of the convex structure 15 can be set to contact the first transverse structure 41 of the concave structure 4; when the RF integrated plug 11 is inserted into the RF test seat gear position 2, the elastic component 3 is completely compressed, and the first transverse structure 41 of the concave structure 4 will also sink accordingly, and the first annular warping structure 42 of the concave structure 4 will shrink inward accordingly, and the transverse structure 151 of the convex structure 15 will contact the first transverse structure 41 of the concave structure 4, and the annular warping structure 152 of the convex structure 15 will contact the first 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, it is achieved that when the convex structure 15 is located at the coaxial seat gear position 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 gear position 2, thereby realizing a physically pluggable RF integrated plug, and providing the possibility for the realization of an RF integrated socket that is compatible with the coaxial seat and RF test seat functions.

[0047] Optionally, combined Figures 1 to 4 , 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 can be set to be an inverted trapezoid, so that the convex structure 15 is protruding in the direction in which the RF integrated plug 11 is inserted into the RF integrated socket 13. Similarly, the cross section of the concave structure 4 along the direction in which the RF integrated socket 13 is inserted into the RF integrated plug 11 can be set to be an inverted trapezoid, so that the concave structure 4 is recessed in the direction in which the RF integrated socket 13 is inserted into the RF integrated plug 11, thereby achieving that the contact area between the convex structure 15 and the concave structure 4 when the convex structure 15 is located at the coaxial seat stop 1 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.

[0048] It should be noted that the embodiment of the present disclosure only exemplarily sets 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 to be an inverted trapezoidal shape, and the embodiment of the present disclosure does not make any specific limitation on this. It is ensured that the convex structure 15 is located at the coaxial seat position 1, and 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 position 2.

[0049] For example, the convex structure 15 may be arranged to be in an arc-shaped convex shape, and correspondingly, the concave structure 4 may be arranged to be in an arc-shaped concave shape. When the RF integrated plug 11 is inserted into the coaxial seat gear 1, the convex structure 15 with an arc-shaped protrusion contacts the concave structure 4 with an arc-shaped concave depression and partially compresses the elastic component 3 through the concave structure 4. The convex structure 15 with an arc-shaped protrusion contacts a partial area of ​​the concave structure 4 with an arc-shaped concave depression to realize the coaxial seat function. When the RF integrated plug 11 is inserted into the RF test seat position 2, the convex structure 15 with an arc-shaped protrusion contacts the concave structure 4 with an arc-shaped depression and compresses all the elastic components 3 through the concave structure 4. The convex structure 15 with an arc-shaped protrusion contacts the entire area of ​​the concave structure 4 with an arc-shaped depression facing the RF integrated plug 11 to realize the RF test seat function. Similarly, when the convex structure 15 is located at the coaxial seat position 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 position 2.

[0050] Combination Figures 1 to 4 , the RF integrated socket 13 may also include a bottom structure 6 and an opening structure 7, and the opening structure 7 and the bottom structure 6 are arranged along the direction in which the RF integrated socket 13 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 13 through the opening structure 7, the opening structure 7 is located at 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.

[0051] 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 13 is electrically connected to the RF signal pad 5 on the RF integrated socket 13, and the RF signal is transmitted to the concave structure 4, and then when the RF integrated plug 11 is inserted into the RF integrated socket 13, the transmission of the RF signal from the RF integrated socket 13 to the RF integrated plug 11 is realized.

[0052] Optionally, combined Figures 1 to 4, a first matching structure 12 may be provided at one end of the columnar structure 14 provided with a convex structure 15, and a second matching structure 9 may be provided at the coaxial seat stop 1 of the RF integrated socket 13 and at the RF test seat stop 2 of the RF integrated socket 13. When the RF integrated plug 11 is inserted into the coaxial seat stop 1, the first matching structure 12 is engaged and fixed with the second matching structure 9 at the coaxial seat stop 1, and when the RF integrated plug 11 is inserted into the RF test seat stop 1, the first matching structure 12 is engaged and fixed with the second matching structure 9 at the RF test seat stop 2.

[0053] Combination Figures 1 to 4 The RF integrated socket 13 may further include a first side wall structure 8, the first side wall structure 8 and the bottom structure 6 surround the space where the RF integrated socket 13 is located, and the inner wall of the first side wall structure 8 is provided with two second matching structures 9 along the direction in which the RF integrated socket 13 is inserted into the RF integrated plug 11, such as a snap-on spring sheet group, the second matching structure 9 adjacent to the opening structure 7, such as the snap-on spring sheet group, is used to fix the RF integrated plug 11 at the coaxial seat gear position 1, and the second matching structure 9 adjacent to the bottom structure 6, such as the snap-on spring sheet group, is used to fix the socket at the RF test seat gear position 2.

[0054] Two layers of second matching structures 9, such as a snap-on spring sheet group, are arranged on the first side wall structure 8 to realize two-stage plugging and unplugging of the RF integrated plug 11 relative to the RF integrated socket 13, thereby realizing a pluggable RF integrated socket 13, and the RF integrated socket 13 is compatible with the functions of the coaxial socket and the RF test socket.

[0055] Optionally, combined Figures 1 to 4 , one of the first matching structure 12 and the second matching structure 9 can be set to be a protruding structure, and the other can be set to be a groove structure, Figures 1 to 4 By way of example, the first matching structure 12 is a groove structure, and the second matching structure 9 is a protrusion structure. Figures 1 to 4 The RF integrated plug 11 may be provided with a first matching structure 12 with a groove structure, and the second matching structure 9 on the first side wall structure 8 of the RF integrated socket 13. For example, the buckle spring piece group is arranged to correspond to the shape of the first matching structure 12 with the groove structure on the RF integrated plug 11. For example, the buckle spring piece 91 is arranged to have a convex structure corresponding to the first matching structure 12 with the groove structure on the RF integrated plug 11. When the RF integrated plug 11 is inserted into the coaxial seat position 1, the first matching structure 12 is engaged and fixed with the second matching structure 9 at the coaxial seat position 1. When the RF integrated plug 11 is inserted into the RF test seat position 1, the first matching structure 12 is engaged and fixed with the second matching structure 9 at the RF test seat position 2. It should be noted that, Figure 4As shown, when the RF integrated plug 11 is inserted into the RF test socket position 2, the snap spring piece 91 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 piece corresponding to the coaxial socket position 1 will be pushed out of the columnar structure of the RF integrated plug 11.

[0056] It should be noted that Figures 1 to 4 The first matching structure 12 is only exemplarily set as a groove structure, and the second matching structure 9 is a protruding structure. The second matching structure 9 can also be set as a groove structure, and the first matching structure 12 is a protruding structure. The embodiment of the present disclosure does not make specific limitations on this. It is ensured that when the RF integrated plug 11 is inserted into the coaxial seat gear 1, the first matching structure 12 is engaged and fixed with the second matching structure 9 at the coaxial seat gear 1. When the RF integrated plug 11 is inserted into the RF test seat gear 1, the first matching structure 12 is engaged and fixed with the second matching structure 9 at the RF test seat gear 2.

Exemplarily, the first matching structure 12 can be set to include multiple independent protrusion structures, and the second matching structure 9 can be set to include multiple independent groove structures, or the first matching structure 12 can be set to include multiple independent groove structures, and the second matching structure 9 can be set to include multiple independent protrusion structures.

[0058] Taking the example that the first matching structure 12 includes multiple independent groove structures and the second matching structure 9 includes multiple independent protrusion structures, the multiple independent groove structures are evenly distributed on the columnar structure 14, the multiple independent protrusion structures are evenly distributed on the inner wall of the first side wall structure 8 of the RF integrated socket 13, the multiple independent groove structures are located in a plane parallel to the bottom structure 6 of the RF integrated socket 13, and the multiple independent protrusion structures are located in a plane parallel to the bottom structure 6 of the RF integrated socket 13.

[0059] When the RF integrated plug 11 is inserted into the corresponding gear position, the multiple independent protrusion structures and the multiple independent groove structures are correspondingly matched in shape to achieve the fixation of the RF integrated plug 11 at the corresponding gear position. Exemplarily, the first matching structure 12 can be set to include four independent groove structures, and the four independent groove structures are evenly distributed on the columnar structure 14, that is, along a plane parallel to the bottom structure 6 of the RF integrated socket 13, the angle between two adjacent independent groove structures is 90°, and the four independent groove structures are located in a plane parallel to the bottom structure 6 of the RF integrated socket 13.

[0060] Optionally, combined Figures 1 to 4, one of the first matching structure 12 and the second matching structure 9 may also be configured to include an annular protrusion structure, and the other may include an annular groove structure. For example, the first matching structure 12 may include an annular protrusion structure, and the second matching structure 9 may include an annular groove structure. Alternatively, the first matching structure 12 may include an annular groove structure, and the second matching structure 9 may include an annular protrusion structure. When the RF integrated plug 11 is inserted into the corresponding gear position, the annular protrusion structure and the annular groove structure match in shape, thereby fixing the RF integrated plug 11 in the corresponding gear position.

[0061] Optionally, combined Figures 1 to 4 The RF integrated plug 11 may further include a top structure 16 and a side wall structure 17 , and the side wall structure 17 and the top structure 16 surround and form a space where the RF integrated plug 11 is located.

[0062] Specifically, the RF integrated socket 13 may further include a first side wall structure 8, the first side wall structure 8 and the bottom structure 6 surround the space where the RF integrated socket 13 is located, for example, the first side wall structure 8 may be set as a cylindrical structure, the bottom structure 6 may be a circular structure, the cylindrical first side wall structure 8 and the circular bottom structure 6 surround the space where the RF integrated socket 13 is located, then the top structure 16 of the RF integrated plug 11 may be a circular structure, the side wall structure 17 may be a cylindrical structure, the cylindrical side wall structure 17 and the circular top structure 16 surround the space where the RF integrated plug 11 is located, so as to realize the physical plugging and unplugging of the RF integrated plug 11 and the RF integrated socket 13.

[0063] For another example, the first side wall structure 8 may be a cubic columnar structure, and the bottom structure 6 may be a rectangular structure, and the cubic columnar first side wall structure 8 and the rectangular bottom structure 6 may surround and form a space where the RF integrated socket 13 is located. Then, the top structure 16 of the RF integrated plug 11 may be a rectangular structure, and the side wall structure 17 may be a cubic columnar structure. The cubic columnar side wall structure 17 and the rectangular top structure 16 may surround and form a space where the RF integrated plug 11 is located, so as to realize the physical plugging and unplugging of the RF integrated plug 11 and the RF integrated socket 13. It should be noted that the top structure 16 and the side wall structure 17 may also be set in other shapes, and the embodiments of the present disclosure do not specifically limit this, and it is sufficient to ensure that the top structure 16 and the side wall structure 17 can surround and form a space where the RF integrated plug 11 is located.

[0064] Optionally, after the RF integrated plug 11 is inserted into the RF integrated socket 13 , the side wall structure 17 and the top structure 16 are electrically connected to at least one ground pad 10 on the RF integrated socket 13 to form a metal shielding structure.

[0065] Figure 5A 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 5 In 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, at least one ground pad 10 may also be provided on the bottom structure 6, and the first 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 the portions of the bottom structure 6 other than the pad are all made of insulating material.

[0066] For example, a plurality of ground pads 10 may be provided on the bottom structure 6, for example Figure 5 Exemplarily, three ground pads 10 are provided on the bottom structure 6. Taking the bottom structure 6 as a rectangle as an example, three ground pads 10 can be provided on three sides of the rectangle. It should be noted that the embodiment of the present disclosure does not limit the specific number and specific position of the ground pads 10 on the bottom structure 6, and it is sufficient to ensure that the first sidewall structure 8 can be electrically connected to at least one ground pad 10.

[0067] The first side wall structure 8 is electrically connected to at least one ground pad 10 to form a metal shielding structure. The first side wall structure 8 is a metal structure. While the first side wall structure 8 forms a space where the RF integrated socket 13 is located with the bottom structure 6, the first side wall structure 8 is electrically connected to at least one ground pad 10 on the bottom structure 6. The ground signal is transmitted on the first side wall structure 8 to form a shielding structure to prevent the external signal of the RF integrated socket 13 from interfering with the transmission process of the RF signal of the RF integrated socket 13. After the RF integrated plug 11 is inserted into the RF integrated socket 13, the side wall structure 17 and the top structure 16 are both in contact with the first side wall structure 8 of the RF integrated socket 13, thereby realizing that the side wall structure 17 and the top structure 16 are both electrically connected to at least one ground pad 10 on the RF integrated socket 13 to form a metal shielding structure to prevent the external signal of the RF integrated plug 11 from interfering with the transmission process of the RF signal of the RF integrated plug 11.

[0068] Optionally, combined Figures 1 to 4 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 horizontal structure 151 and the outer surface of the corresponding annular warping structure 152 may be covered with a passivation metal layer.

[0069] Specifically, the columnar structure 14 is formed by coating the copper column with insulating material. The copper column itself is very suitable for the transmission of radio frequency signals. The copper at the lower end of the copper column that contacts the radio frequency integrated socket 13 is exposed and gold-plated. The copper exposed at the lower end of the copper column is used to connect with the radio frequency signal on the radio frequency integrated socket 13. In addition, the contact point between the lower end of the copper column and the radio frequency integrated socket 13 is gold-plated to effectively prevent oxidation of the contact point, and further reduce the contact impedance between the radio frequency integrated plug 11 and the radio frequency integrated socket 13.

[0070] Optionally, the end of the columnar structure 14 away from the convex structure 15 can be fixed and insulated from the top structure 16. 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 end of the columnar structure 14 away from the convex structure 15 needs to be insulated from the top structure 16.

Figures 1 to 6 , Figure 6 The leftmost figure shows the structure before the RF integrated socket 13 and the RF integrated plug 11 are plugged in, the middle figure shows the structure after the RF integrated plug 11 is inserted into the coaxial seat stop 1, and the rightmost figure shows the structure after the RF integrated plug 11 is inserted into the RF test seat stop 2. Among them, the upper part is the RF integrated plug 11, the lower part is the RF integrated socket 13, G indicates that the terminal is grounded, and S indicates that the terminal is connected to the RF signal.

[0072] Optionally, the columnar structure 14 may include a copper column and an insulating material covering a portion of the copper column, and 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 be equal 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 to improving the consistency of the impedance 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.

[0073] The embodiment of the present disclosure also provides a connector, which includes an RF integrated socket and the RF integrated plug as described in the above embodiment, the RF integrated socket includes a concave structure and a coaxial seat gear and an RF test seat gear, the concave structure is electrically connected to the RF signal pad on the RF integrated socket, therefore, the connector provided by the embodiment of the present disclosure has the beneficial effects of the above embodiment, which will not be repeated here.
