Description

Technical Field

[0001] This disclosure relates to the mechanical field, and more particularly to a radio frequency connector and terminal. Background Technology

[0002] Taking mobile phones as an example, with the development of 5G (5th generation wireless systems) technology, 5G support will become a standard feature of mobile terminals. This requires mobile phones to utilize as many antennas as possible within their bezels to support 5G. Combined with the increasing maturity of flexible screen technology, foldable phones are attracting more and more consumer attention. Therefore, how to incorporate more antennas into foldable phones to accommodate 5G technology has become one of the urgent problems to be solved.

[0003] Generally, foldable phones consist of two foldable components, with the motherboard located on only one of them. The antenna and antenna-related switches are located on the component with the motherboard. To accommodate more antennas, antennas would need to be designed on both foldable components. However, the antenna radiators on the component without the motherboard need to be connected to the motherboard via cables. These cables must pass through the folded area, and most cables do not support repeated large-angle bending. Therefore, currently, foldable phones only design antennas on the component with the motherboard, which significantly limits antenna design options. Summary of the Invention

[0036] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects:

[0037] As can be seen from the above embodiments, this disclosure effectively ensures the quality and stability of the antenna RF signal within the terminal by dividing the RF connector into a first connection terminal and a second connection terminal, and electrically connecting the first connection terminal and the second connection terminal. By connecting the two connecting wires via a rotating shaft, it is possible to connect the antenna of the first part of the foldable terminal to the motherboard of the second part, or to connect the antenna of the second part of the foldable terminal to the motherboard of the first part. Furthermore, the first and second connecting wires do not need to be folded.

[0038] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

[0039] The accompanying drawings, which are incorporated in and form a part of this specification, illustrate embodiments consistent with this disclosure and, together with the description, serve to explain the principles of this disclosure.

[0040] Figure 1 This is one of the schematic diagrams of a partial structure of a terminal according to an exemplary embodiment;

[0041] Figure 2This is one of the schematic diagrams of a partial structure of an RF connector according to an exemplary embodiment;

[0042] Figure 3 This is a second schematic diagram of a partial structure of an RF connector according to an exemplary embodiment. Detailed Implementation

[0043] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses consistent with some aspects of this disclosure as detailed in the appended claims.

[0044] In the description of this invention, it should be understood that the terms "center", "upper", "lower", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

[0045] This disclosure provides a radio frequency connector, which mainly includes:

[0046] The rotating shaft 100 includes a first connecting terminal 110 and a second connecting terminal, the first connecting terminal 110 and the second connecting terminal forming a rotating shaft structure that can rotate relative to each other, and the first connecting terminal 110 and the second connecting terminal forming an electrical connection.

[0047] The first connecting line 200 is connected to the first connecting terminal 110;

[0048] The second connecting line 300 is connected to the second connecting terminal.

[0049] In this embodiment, when the first connecting terminal 110 rotates relative to the second connecting terminal, it drives the first connecting line 200 and the second connecting line 300 to rotate. The antenna and its RF circuit are connected using the two connecting lines of the RF connector. The two connecting lines are connected by a rotating shaft, enabling the connection of the antenna of the first part of the foldable terminal to the motherboard of the second part, or vice versa. Therefore, when the RF connector is used within the terminal, if antennas are provided in both the first and second parts of the foldable terminal, the first or second connecting line does not need to be folded when passing through the folded position.

[0050] Both the first connecting terminal 110 and the second connecting terminal are conductive. The first connecting terminal 110 and the second connecting terminal form an electrical connection within the RF connector through contact. The pivot structure 100 formed by the first connecting terminal 110 and the second connecting terminal ensures that the electrical connection is maintained regardless of rotation. Compared to existing RF connectors, this embodiment of the present disclosure only changes the relative contact position of the first connecting terminal 110 and the second connecting terminal through this arrangement, but does not change the conductive parameters of the RF connector as a connector (e.g., impedance, operating frequency, or transmission power).

[0051] In other alternative embodiments, the rotating shaft 100 further includes:

[0052] The rotating shaft body 120 has a first connecting terminal 110 disposed on the first rotating member 121 of the rotating shaft body 120, and a second connecting terminal disposed on the second rotating member 122 of the rotating shaft body 120.

[0053] When the first rotating member 121 rotates relative to the second rotating member 122, it will cause the first connecting terminal 110 and the second connecting terminal to rotate relative to each other. The rotating shaft body 120 can be used to support the first connecting terminal 110 and the second connecting terminal, and assist the rotation of the first connecting terminal 110 and the second connecting terminal. When this RF connector is used in a terminal, the rotating shaft body 120 can also drive the first part and the second part of the folding terminal to rotate, ensuring that the terminal folds smoothly.

[0054] In practical applications, the rotating shaft body 120 can be a hinge or a hinge-button joint. Both the first rotating component 121 and the second rotating component 122 can be made of materials with good strength and fatigue resistance, such as metals or alloys.

[0055] At least at the point where the first rotating member 121 and the second rotating member 122 are connected, the first rotating member 121 and the second rotating member 122 are cylindrical or annular so that the first rotating member 121 and the second rotating member 122 can rotate relative to each other.

[0056] Unrestricted, such as Figure 1As shown, one of the first rotating member 121 and the second rotating member 122 can be a bushing structure, and the other can be a shaft core structure, with the shaft core and bushing coaxially arranged. The bushing of the rotating shaft 100 has a circular through hole arranged along the axis of the bushing, and the shaft core includes a cylindrical portion. The cylindrical portion of the shaft core passes through the through hole and rotates relative to the bushing through the through hole. The maximum relative rotation angle between the first rotating member 121 and the second rotating member 122 can reach 360°. The mutual rotation angle between the first connecting terminal 110 and the second connecting terminal can be the same as the mutual rotation angle between the first rotating member 121 and the second rotating member 122. Consequently, the first connecting line 200 and the second connecting line 300 can also achieve a maximum rotation angle of 360°, enabling large-angle rotation of the first connecting line 200 and the second connecting line 300.

[0057] In other alternative embodiments, the rotating shaft 100 further includes:

[0058] The shielding shell; both the first connecting terminal 110 and the second connecting terminal are located inside the shielding shell.

[0059] The connection between the first connecting terminal 110 and the second connecting terminal enables the RF connector to conduct, ensuring the transmission of the antenna signal. The shielding shell can shield the antenna signal, improving its quality and stability.

[0060] The shielding shell can be a one-piece structure. In this case, the shielding shell can be fixed only to the outside of the first connecting terminal 110 or the outside of the second connecting terminal. When the first connecting terminal 110 and the second connecting terminal are connected, both the first connecting terminal 110 and the second connecting terminal are located inside the shielding shell.

[0061] Alternatively, in other optional embodiments, the shielding shell is made into a split two-part structure, including a first shielding shell 130 and a second shielding shell 140. Specifically, the first shielding shell 130 is disposed outside the first connecting terminal 110; the second shielding shell 140 is disposed outside the second connecting terminal; the first shielding shell 130 and the second shielding shell 140 together enclose a receiving space, and both the first connecting terminal 110 and the second connecting terminal are located within the receiving space.

[0062] like Figure 1 As shown, the first shielding shell 130 and the second shielding shell 140 are tightly connected, and both can rotate with the relative rotation of the first connecting terminal 110 and the second connecting terminal. In order not to affect the mutual rotation between the first shielding shell 130 and the second shielding shell 140, at least at the connection between the first shielding shell 130 and the second shielding shell 140, both the first shielding shell 130 and the second shielding shell 140 have circular or arc-shaped mating surfaces.

[0063] like Figures 1 to 3As shown, when the rotating shaft 100 includes the rotating shaft body 120, the first connecting terminal 110 is connected to the first rotating member 121 through the first shielding shell 130, and the second connecting terminal is connected to the second rotating member 122 through the second shielding shell 140. The first rotating member 121 and the second rotating member 122, the first connecting terminal 110 and the second connecting terminal, and the first shielding shell 130 and the second shielding shell 140 can all rotate synchronously. Regardless of how the rotating shaft body 120 rotates, the first connecting terminal 110 and the second connecting terminal always maintain an electrical connection.

[0064] Optionally, the first connecting terminal 110, the second connecting terminal, the first shielding shell 130, and the second shielding shell 140 can all be made of conductor materials such as metals or alloys, for example, copper, stainless steel, gold-plated copper, silver-plated copper, or nickel-plated copper.

[0065] In other alternative embodiments, the first connection terminal 110 includes: a connection bayonet 111;

[0066] The second connection terminal includes: a connection inner core 150;

[0067] Insert the inner core 150 into the connector slot 111.

[0068] In practical applications, the connecting inner core 150 can be coaxially set with the connecting bayonet 111, and the connecting inner core 150 can be coaxially set with the rotating shaft body 120, allowing the connecting inner core 150 to rotate within the connecting bayonet 111.

[0069] Unrestricted, the connecting core 150 is cylindrical.

[0070] In addition to being cylindrical, the connecting core 150 can also be conical or frustum-shaped or other shapes.

[0071] Furthermore, the first connecting terminal 110 and the second connecting terminal can also take the form of gold fingers or solder pads. Here, the first connecting terminal 110 can be a collective term for one or more connecting terminals; similarly, the second connecting terminal can also be a collective term for one or more connecting terminals. If there are multiple first connecting terminals 110, these multiple connecting terminals are arranged side-by-side. If there are multiple second connecting terminals, these multiple connecting terminals are arranged side-by-side.

[0072] In other alternative embodiments, the first connection line 200 includes: a coaxial cable, an FPC cable, a PI cable, or an LCP cable;

[0073] The second connecting line 300 includes: a coaxial cable, an FPC cable, a PI cable, or an LCP cable.

[0074] Coaxial cable, FPC line, PI line, and LCP line all refer to signal transmission carriers using different types of substrates. FPC line stands for Flexible Printed Circuit. PI line refers to a transmission line using Polyimide as the substrate, and LCP line refers to a transmission line using Liquid Crystal Polymer as the substrate.

[0075] In one specific embodiment, taking a coaxial cable as an example, a coaxial cable generally includes a conductor core located at the center and a shell coaxially covering the conductor core. The shell shields the conductor core to ensure the quality and stability of signal transmission within the conductor core. The conductor core of the coaxial cable used as the first connecting line 200 is connected to the first connecting terminal 110, and the shell of the coaxial cable used as the first connecting line 200 is connected to the first shielding shell 130. Similarly, the conductor core of the coaxial cable used as the second connecting line 300 is connected to the second connecting terminal, and the shell of the coaxial cable used as the second connecting line 300 is connected to the second shielding shell 140.

[0076] This disclosure also provides a terminal, which includes the radio frequency connector described in any of the above embodiments.

[0077] The terminal is foldable, comprising a first part and a second part that can be folded relative to each other. The terminal can be a foldable mobile phone, foldable TV, or foldable tablet, or an electronic product such as a laptop computer that includes a display screen and a keyboard that can rotate relative to each other. One of the first connecting line 200 and the second connecting line 300 can be located on the first part of the terminal, and the other can be located on the second part of the terminal; that is, both foldable parts of the terminal can serve as antenna carriers. For electronic products such as laptop computers, the display screen and keyboard can be folded or unfolded.

[0078] In other alternative embodiments, the rotating shaft 100 further includes:

[0079] The rotating shaft body 120 has a first connecting terminal 110 disposed on a first rotating member 121 of the rotating shaft body 120, and a second connecting terminal disposed on a second rotating member 122 of the rotating shaft body 120.

[0080] The first rotating component 121 is connected to the first support plate 400 of the terminal, and the second rotating component 122 is connected to the second support plate 500 of the terminal. The first rotating component 121 and the second rotating component 122 drive the first support plate 400 and the second support plate 500 to rotate.

[0081] The first part of the terminal includes a first support plate 400, and the second part includes a second support plate 500. The first support plate 400 and the second support plate 500 rotate with the rotation of the first rotating member 121 and the second rotating member 122, thereby realizing the folding of the first part and the second part of the terminal.

[0082] Unrestricted, such as Figure 2 and Figure 3 As shown, the second rotating member 122 comprises upper and lower parts. The lower part 1221 is connected to the first rotating member 121, and the upper part 1222 is connected to the top of the second shielding shell 140. The second support plate 500 connects both the upper and lower parts of the second rotating member 122, making the two parts of the second rotating member 122 a single unit. The bottom of the first shielding shell 130 is connected to the first rotating member 121 and is a cylindrical shape with its opening facing upwards. The second shielding shell 140 is a cylindrical shape with its opening facing downwards and is coaxially arranged with the first shielding shell 130. When the first connecting terminal 110 and the second connecting terminal are connected, the first shielding shell 130 and the second shielding shell 140 are tightly connected. This structure further ensures synchronous rotation between the first rotating member 121 and the second rotating member 122, between the first connecting terminal 110 and the second connecting terminal, and between the first shielding shell 130 and the second shielding shell 140.

[0083] In other alternative embodiments, the first support plate 400 includes a first groove 410, and the first connecting line 200 is disposed in the first groove 410;

[0084] The second support plate 500 includes a second groove 510, and the second connecting line 300 is disposed in the second groove 510.

[0085] Generally, the first support plate 400 stores the first connecting wire 200 through the first groove 410, and the second support plate 500 stores the second connecting wire 300 through the second groove 510.

[0086] like Figure 1 As shown, the first connecting line 200 matches the inner surface of the first groove 410, meaning the first connecting line 200 and the first groove 410 are conformal; the second connecting line 300 matches the inner surface of the second groove 510, meaning the second connecting line 300 and the second groove 510 are conformal. This conformal design allows the first connecting line 200 to maintain the same shape as the first support plate 400, or the second connecting line 300 to maintain the same shape as the second support plate 500, improving overall integrity, reducing the space occupied by the connecting lines inside the terminal, and reducing interference of the connecting lines with other internal structures of the terminal.

[0087] In other alternative embodiments, the first connecting line 200 connects to the antenna, and the second connecting line 300 connects to the radio frequency module; or

[0088] The first connecting line 200 connects to the radio frequency module, and the second connecting line 300 connects to the antenna.

[0089] Typically, the radio frequency (RF) module is located on either the first or second part of the terminal. When the RF module is located in the first part, the first connecting line 200 can be directly connected to the RF module. The second connecting line 300, located in the second part, is connected to the first connecting line 200 via a hinge 100, enabling signal transmission. Similarly, when the RF module is located in the second part, the second connecting line 300 can be directly connected to the RF module. The first connecting line 200, located in the first part of the terminal, is connected to the second connecting line 300 via a hinge 100, enabling signal transmission.

[0090] Generally, the radio frequency (RF) module is located on the motherboard, which also includes a baseband module that communicates with the RF module.

[0091] In other alternative embodiments, the terminal further includes:

[0092] A first housing is connected to a first rotating member 121 and / or a first support plate 400, and a first connecting line 200 is located inside the first housing;

[0093] The second housing is connected to the second rotating member 122 and / or the second support plate 500, and the second connecting line 300 is located inside the second housing;

[0094] The flexible screen is covered on the back of the first housing, the second housing, and the pivot 100, and deforms as the first housing rotates relative to the second housing.

[0095] The terminal has a first housing and a second housing. The flexible screen is a foldable display, such as a flexible organic light-emitting diode (OLED) screen. Under the action of the first and second housings, the flexible screen folds or unfolds. Folding includes an inward fold, where the flexible screen is folded inward, with the first and second housings on the outside, protecting the flexible screen and reducing the terminal's footprint for easier storage. Folding also includes an outward fold, where the flexible screen is folded around the pivot 100 into two opposing parts. These two parts can display different information, allowing two people to use the screen simultaneously. When unfolded, the flexible screen provides a large-screen effect.

[0096] In other alternative embodiments, the first housing and the first support plate 400 are a single unit or a separate unit.

[0097] The second shell and the second support plate 500 are either a single unit or separate units.

[0098] When a one-piece structure is adopted, the unreliability risks when the first support plate 400 is connected to the first housing and the second support plate 500 is connected to the second housing can be reduced. Specifically, the first housing and the first support plate 400, and the second housing and the second support plate 500 can be integrally formed by machining or molding.

[0099] When a split structure is adopted, the first support plate 400 and the first housing can be arranged in parallel or attached together, and the second support plate 500 and the second housing can be arranged in parallel or attached together, so as to improve the integrity of the first support plate 400 and the first housing, and the integrity of the second support plate 500 and the second housing, while minimizing the increase in terminal thickness due to the setting of the first support plate 400 and the second support plate 500.

[0100] The first and second housings can also be a single, integrated structure. Specifically, the portion between the first and second housings is a flexible section, corresponding to the rotating shaft 100. When an external force in a predetermined direction is applied to the first and / or second housings, the flexible section deforms, causing the first rotating member 121 and the second rotating member 122 to rotate relative to each other, thereby causing the first housing to rotate relative to the second housing. The predetermined direction can be clockwise or counterclockwise. The flexible section can be made of materials such as flexible glass, flexible metal, or flexible rubber.

[0101] In the terminal, the axis of the rotating shaft 100 and the folding axis of the flexible screen are coaxial to improve the overall integrity and reliability of the terminal.

[0102] In a specific example, taking a mobile phone as an example, a foldable screen phone typically includes two foldable parts: a first part and a second part. The motherboard is usually located on one of these parts, for example, on the first part. The first part includes a first housing, and the second part includes a second housing. The motherboard is located inside the first housing. The radio frequency module and the baseband module are both located on this motherboard. Referring to a candybar phone with a rigid screen, the antenna and antenna-related switches can be placed in the first part, or the wiring can be routed inside the motherboard. With the application of 5G technology, the number of antennas has increased significantly, and both the first and second parts can be used as carriers for antenna design. The hinge body 120 includes two parts: a first rotating component 121 and a second rotating component 122. A first connecting terminal 110 is fixed to the first rotating component 121, and a second connecting terminal is fixed to the second rotating component 122. A first connecting line 200 is connected to the first connecting terminal 110, and a second connecting line 300 is connected to the second connecting terminal, thereby achieving a large-angle bend in the two connecting lines. Both the first connecting line 200 and the second connecting line 300 are formed using coaxial cables. The first connecting line 200 and the second connecting line 300 can be customized as needed and are designed to conform to the corresponding support plate.

[0103] The features disclosed in the several product embodiments provided in this application can be arbitrarily combined without conflict to obtain new product embodiments.

[0104] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein. This disclosure is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of this disclosure are indicated by the claims.

[0105] It should be understood that this disclosure is not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this disclosure is limited only by the appended claims.
