Description

Technical Field

[0001] This disclosure relates to the field of radio frequency communication technology, and more specifically, to a switchable radio frequency connector assembly. Background Technology

[0002] Existing connector assemblies are either only suitable for general circuit switches and not for radio frequency circuits, or their switching method requires connecting / removing a new connector, making switching inconvenient and quick, resulting in poor switching feel, or the connector assembly uses a spring-loaded structure, which is detrimental to the transmission of radio frequency signals.

[0003] In addition, most existing connector assemblies use inelastic rigid connections, which are prone to wear during switching and are not suitable for applications that require multiple switching operations. Summary of the Invention

[0004] As mentioned above, the prior art suffers from the following technical problems: existing connector assemblies are not suitable for radio frequency (RF) circuits, and the switching methods are complex and inconvenient. The inventors of this disclosure have innovatively conceived of using a flexible contact method to design RF connector assemblies, thereby enabling the RF connector assemblies according to this disclosure to transmit RF signals stably.

[0005] Specifically, based on the above considerations, the inventors of this disclosure propose the following switchable RF connector assembly, which includes:

[0006] At least two radio frequency connectors, wherein the at least two radio frequency connectors are configured as resilient contact radio frequency connectors;

[0007] A switching component configured to rotate about a central axis to selectively select two RF connectors from the at least two RF connectors for electrical connection; and

[0008] A drive member configured to drive the switching assembly to rotate about the central axis.

[0009] The switchable RF connector assembly according to this disclosure can achieve stable RF signal transmission during switching, and also makes the target position when the switching assembly rotates more clearly, which is convenient for users to select and switch.

[0010] In one embodiment of this disclosure, the RF connector includes a first RF connector and a second RF connector. In another embodiment of this disclosure, the switching component is electrically connected to both the first RF connector and the second RF connector simultaneously. In this manner, the switching component can select two RF connectors from at least two RF connectors for electrical connection, preferably, the two selected RF connectors for electrical connection are two adjacent RF connectors.

[0011] In one embodiment according to this disclosure, the switching component includes:

[0012] A cam conductor, configured to rotate about the central axis and selectively select two RF connectors from the RF connectors for electrical connection;

[0013] An insulator, the insulator being configured to rotate about the central axis; and

[0014] Fasteners configured to secure the cam conductor to the insulator.

[0015] Preferably, in one embodiment according to the present disclosure, the cam conductor is configured as a U-shaped cam conductor or an angled cam conductor. More preferably, in one embodiment according to the present disclosure, the cam conductor has a chamfered structure between adjacent connecting surfaces.

[0016] In this way, the two selected RF connectors can be electrically connected via a cam conductor that can rotate around the central axis, and the chamfered structure makes the switching smoother, reduces wear, and improves the service life of the switching components.

[0017] In one embodiment according to this disclosure, the radio frequency connector includes a flexible center conductor, the flexible center conductor comprising:

[0018] A first conductor segment, the first conductor segment being configured for electrical connection with a mating external center conductor;

[0019] The second conductor segment is configured to be electrically connected to the switching component;

[0020] A third conductor segment, wherein the third conductor segment is disposed between the first conductor segment and the second conductor segment; and

[0021] A spring structure for applying a force away from the first conductor segment to the second conductor segment.

[0022] The flexible contact RF connector constructed in this way can ensure a good connection between the flexible center conductor and the corresponding cam conductor, thereby ensuring stable transmission of RF signals. It can also connect the first conductor segment and the second conductor segment through the third conductor segment, thereby ensuring good transmission of RF signals inside the RF connector.

[0023] Preferably, in one embodiment according to this disclosure, the end of the second conductor segment is a planar contact portion, the cross-section of which is larger than the cross-section of the third conductor segment, and the planar contact portion makes elastic contact with the cam conductor. Those skilled in the art should understand that, here, the end of the second conductor segment does not necessarily have to be planar, nor does it necessarily have to be such that the cross-section of the planar contact portion is larger than the cross-section of the third conductor segment.

[0024] In one embodiment of the present disclosure, the switchable RF connector assembly further includes: a housing, the housing further having a receiving cavity for accommodating the switching assembly; and a top cover mounted on the housing, the drive member being held on the top cover and mechanically connected to the switching assembly. Preferably, in one embodiment of the present disclosure, the housing is made of a metallic material. In this way, the metallic housing can serve as a shielding layer for the coaxial structure transmitting RF signals, thereby ensuring that the RF signals transmitted in the central conductor are not interfered with by external signals.

[0025] In one embodiment of the present disclosure, the housing is provided with a connection interface, through which the at least two radio frequency connectors can be electrically connected to the switching component.

[0026] Preferably, in one embodiment according to this disclosure, the driving member is configured as: a knob, wherein the knob is configured for manual rotation to drive the switching component to rotate around the central axis; or an electric driving member, wherein the electric driving member is configured to receive a control signal to drive the switching component to rotate around the central axis. In this way, the driving member according to this disclosure can be configured as either manually driven or electrically driven according to the needs of a specific application scenario. For example, in application scenarios where personnel have difficulty accessing the site, it is suitable to configure the driving member as electrically driven, thereby enabling remote transmission of control signals to the electric driving member, thereby automating the switching component's operation and facilitating control; while in some application scenarios where personnel can easily access the site, it is suitable to configure the driving member as a manually driven knob.

[0027] Optionally or alternatively, in one embodiment according to this disclosure, the knob includes: a knob protrusion configured to be manually driven via it; a limiting portion configured to mechanically engage with a stop on a mating housing top cover in the assembled state; and a fixing portion configured to be fixedly connected to a mating switching component in the assembled state. In this way, in the assembled state, the knob can be fixedly connected to the mating switching component via the fixing portion, thereby enabling rotation of the knob to drive rotation of the switching component. Furthermore, because the knob has a knob protrusion, it can be manually driven via it. Moreover, due to the limiting portion, the knob can move in a desired manner, rather than rotating freely without restriction. Preferably, in one embodiment according to this disclosure, the stop is configured as a stop protrusion or an eccentric limiting frame structure. More preferably, in one embodiment according to this disclosure, the knob protrusion can only rotate 180 degrees back and forth. It should be understood by those skilled in the art that the knob can, of course, be moved in a desired manner, such as along a certain angle.

[0028] In summary, the switchable RF connector assembly proposed in this disclosure can achieve stable RF signal transmission during switching, and also makes the target position of the switching assembly more clear when rotating, which is convenient for users to select and switch.

[0040] Various exemplary embodiments of this disclosure are described in detail below with reference to the accompanying drawings. While the exemplary methods and apparatuses described below include software and / or firmware executed on hardware among other components, it should be noted that these examples are merely illustrative and should not be considered limiting. For example, it is conceivable that any or all hardware, software, and firmware components may be implemented exclusively in hardware, exclusively in software, or in any combination of hardware and software. Therefore, although exemplary methods and apparatuses have been described below, those skilled in the art will readily understand that the examples provided are not intended to limit the ways in which these methods and apparatuses may be implemented.

[0041] Furthermore, the flowcharts and block diagrams in the accompanying drawings illustrate the architecture, functionality, and operation of possible implementations of methods and systems according to various embodiments of this disclosure. It should be noted that the functions marked in the blocks may occur in a different order than that shown in the drawings. For example, two consecutively indicated blocks may actually be executed substantially in parallel, or they may sometimes be executed in reverse order, depending on the functions involved. It should also be noted that each block in the flowcharts and / or block diagrams, and combinations of blocks in the flowcharts and / or block diagrams, may be implemented using a dedicated hardware-based system that performs the specified function or operation, or using a combination of dedicated hardware and computer instructions.

[0042] As mentioned above, the prior art suffers from the following technical problems: existing connector assemblies are not suitable for radio frequency (RF) circuits, and the switching methods are complex and inconvenient. The inventors of this disclosure have innovatively conceived of using a flexible contact method to design RF connector assemblies, thereby enabling the RF connector assemblies according to this disclosure to transmit RF signals stably.

[0043] Figure 1 A schematic diagram of a switchable RF connector assembly 100 according to an embodiment of the present disclosure in an disassembled state is shown, while Figure 2 A schematic diagram of a switchable radio frequency connector assembly 100 in an assembled state, according to one embodiment of the present disclosure, is shown. Figure 1 and Figure 2 As can be seen from this, the switchable RF connector assembly 100 according to this disclosure mainly includes RF connectors 7, 8, and 9. Here, the connector types of the three RF connectors 7, 8, and 9 are, for example, TNC male, TNC female, and BNC female. Of course, those skilled in the art should understand that the connector types can also be replaced with other types of connectors. Simultaneously, these three RF connectors 7, 8, and 9 are constructed as resilient contact RF connectors. Furthermore, the switchable RF connector assembly 100 according to this disclosure also includes a switching assembly 20 with a cam conductor 2 (other components will be further described later). The switching assembly 20 is configured to rotate around a central axis (e.g., Figure 1 The cam conductor 2 rotates in the vertical direction (as shown), thereby allowing it to selectively connect RF connector 7 and RF connector 9 or RF connector 7 and RF connector 8 from the three RF connectors 7, 8, and 9 for electrical connection. Figure 1 In the illustration, the cam conductor 2 of the switching assembly 20 electrically connects the RF connector 7 and the RF connector 9; furthermore, the switchable RF connector assembly 100 according to this disclosure also includes a drive member such as a knob 5, which is configured to drive the switching assembly 20 such that the cam conductor 2 rotates around the central axis (e.g., Figure 1 Rotational motion is performed in the vertical direction shown. Furthermore, from... Figure 1 and Figure 2 It can also be seen that the switchable RF connector assembly 100 includes a housing 1 and a top cover 4 covering the housing 1. The housing 1 is also provided with a receiving cavity 12 for accommodating the switching component 20. The driving member is fixed to the top cover 4. The top cover 4 is connected and fixed to the housing 1 of the switchable RF connector assembly 100 by, for example, four screws 11.

[0044] To more clearly illustrate how the switching assembly 20 switches between three RF connectors 7, 8, and 9 configured as flexible contact RF connectors to selectively electrically connect RF connector 7 and RF connector 8, or RF connector 7 and RF connector 9, in such a way that the switching assembly 20 can select two RF connectors from at least two RF connectors for electrical connection, preferably, the two RF connectors selected for electrical connection are two adjacent RF connectors. Figure 3A A cross-sectional view of a switchable RF connector assembly 100 according to an embodiment of the present disclosure is shown in horizontal cross-section. Figure 3B A cross-sectional view of a switchable RF connector assembly 100 according to an embodiment of the present disclosure is shown in vertical cross-section.

[0045] from Figure 3A and Figure 3B As can be seen from this, in one embodiment according to the present disclosure, at least a portion of the drive member is located outside the housing 1 and mechanically connected to the switching assembly 20. Preferably, in one embodiment according to the present disclosure, the housing 1 is made of a metallic material. Furthermore, the housing 1 is provided with a connection interface through which the at least two RF connectors 7, 8, and 9 can be electrically connected to the switching assembly 20. In this way, the metallic housing 1 can serve as a shielding layer for the coaxial structure transmitting RF signals, thereby ensuring that the RF signals transmitted in the central conductor are not interfered with by external signals.

[0046] The RF connector includes a flexible center conductor, for example, a center conductor configured as a pogopin. The flexible center conductor of the RF connector 7 comprises the following four parts: a first conductor segment 701, configured to electrically connect with the center conductor of a mating external RF cable; a second conductor segment 704, configured to electrically connect with a switching assembly 20, for example, electrically connected with a cam conductor 2 of the switching assembly 20; a third conductor segment 702, disposed between the first conductor segment 701 and the second conductor segment 704, preferably, the end of the second conductor segment 704 is a planar contact portion, the cross-section of which is larger than the cross-section of the third conductor segment 702, the planar contact portion making a flexible contact with the cam conductor 2; and a spring structure 703, the spring structure 703 for applying a force away from the first conductor segment 701 to the second conductor segment 704. Those skilled in the art will understand that, here, the end of the second conductor segment 704 is not necessarily planar, nor is it necessary for the cross-section of the planar contact portion to be larger than the cross-section of the third conductor segment 702. Similarly, the elastic center conductor of the RF connector 8 comprises the following four parts: a first conductor segment 801, configured to be electrically connected to the center conductor of a mating external RF cable; a second conductor segment 804, configured to be electrically connected to the switching assembly 20, for example, to the cam conductor 3 of the switching assembly 20; a third conductor segment 802, disposed between the first conductor segment 801 and the second conductor segment 804, the end of the second conductor segment 804 being a planar contact portion, the cross-section of which is larger than the cross-section of the third conductor segment 802, the planar contact portion making elastic contact with the cam conductor 2; and a spring structure 803, the spring structure 803 being used to apply a force away from the first conductor segment 801 to the second conductor segment 804. Those skilled in the art should understand that, here, the end of the second conductor segment 804 does not necessarily have to be planar, nor does it necessarily have to make the cross-section of the planar contact portion larger than the cross-section of the third conductor segment 802. Furthermore, from... Figure 3A and Figure 3BIt can also be seen that the elastic center conductor of the RF connector 9 comprises the following four parts: a first conductor segment 901, configured to electrically connect with the center conductor of a mating external RF cable; a second conductor segment 904, configured to electrically connect with the switching assembly 20, for example, to the cam conductor 3 of the switching assembly 20; a third conductor segment 902, disposed between the first conductor segment 901 and the second conductor segment 904, the end of the second conductor segment 904 being a planar contact portion, the cross-section of which is larger than the cross-section of the third conductor segment 902, the planar contact portion making elastic contact with the cam conductor 2; and a spring structure 903, the spring structure 903 being used to apply a force away from the first conductor segment 901 to the second conductor segment 904. Those skilled in the art should understand that the end of the second conductor segment 904 does not necessarily have to be planar, nor does it necessarily have to be such that the cross-section of the planar contact portion is larger than the cross-section of the third conductor segment 902. Three pogo pins provide spring force to ensure conduction, and the common spring force, combined with the cam conductor of the central switching component 20, enables the rotational switching positions. Here, the switchable RF connector assembly 100 has two positions. Figure 4A A top view of the top cover 4 of a switchable RF connector assembly 100 according to one embodiment of the present disclosure is shown. Figure 4A As shown, when knob arrow 401 is turned to the left, both the left RF connector 8 and the upper RF connector 7 are connected; when knob arrow 402 is turned to the right (as shown), ... Figure 4A (As shown in the image), the RF connector 9 on the right and the RF connector 7 on the top are both conductive. There is a clear tactile feedback when switching. This type of flexible contact RF connector ensures a good connection between the flexible center conductor and the corresponding cam conductor 2, thus ensuring stable RF signal transmission. It also ensures a good connection between the first and second conductor segments via the third conductor segment, thereby ensuring good RF signal transmission within the RF connector.

[0047] from Figure 3BIt can also be seen that the cam conductor 2 is fixed to the insulator 3, for example, by a fastener 10. That is, it is sufficient to set a cam conductor 2 at the same height as the second conductor segments 704, 804, and 904 on the insulator 3. Moreover, the cam conductor 2 is constructed, for example, as a U-shaped cam conductor or an angled cam conductor. Preferably, the cam conductor 2 is configured as a U-shaped structure. The cam conductor 2 has a contact surface for each RF connector. The contact surface is a planar structure that can achieve elastic contact with the planar contact portion at the end of the second conductor segment. This results in a large contact surface and a more stable contact. The cam conductor 2 has a chamfer structure 201 between adjacent contact surfaces (e.g., via...). Figure 5C (As shown). In this way, the two selected RF connectors 7 and 8 or 7 and 9 can be electrically connected via the cam conductor 2, which is capable of rotating around the central axis, and the presence of the chamfered structure 201 makes the switching smoother, reduces wear, and increases the service life of the switching assembly 20.

[0048] The following will use Figure 4A , Figure 4B as well as Figure 4C Let's introduce the top cover 4 of the switchable RF connector assembly 100. Among them, Figure 4A A top view of the top cover 4 of a switchable RF connector assembly 100 according to one embodiment of the present disclosure is shown. Figure 4B A bottom view of the top cover 4 of a switchable RF connector assembly 100 according to one embodiment of the present disclosure is shown; while Figure 4C A cross-sectional view of the top cover 4 of a switchable RF connector assembly 100 according to one embodiment of the present disclosure is shown. Figure 4A It can be seen that the top cover 4, for example, is via Figure 4B The hole 403 shown is secured to the housing of the switchable RF connector assembly 100 by means of screws. Furthermore, Figure 4A Two conduction markers 401 and a rotatable range 402 are shown, that is, in Figure 4A When the knob is in the position shown, it can only be rotated clockwise until arrow 401 points to the left, and cannot be rotated counterclockwise. When the knob is rotated 180 degrees, i.e., when arrow 401 on the knob is pointing to the left, the knob can only be rotated counterclockwise 180 degrees until arrow 401 points to the right. Therefore, it can be seen that the knob can only rotate 180 degrees back and forth. Figure 4CAs can be seen, the bottom of the top cover 4 is provided with a receiving groove 13. The knob 5 includes a knob protrusion 51 extending upward from the top cover 4, a disc 52 received in the receiving groove 13, a limiting part 6 extending from the side of the disc 52, and a fixing fitting part 501 extending beyond the top cover 4 from the bottom of the disc 52. The disc 52 is located in the receiving groove 13 and is biased to one side, so that when the knob 5 is rotated, the side of the receiving groove 13 near the disc 52 acts as a stop (e.g., ...). Figure 4B The frame on the side of the limiting part 6 (shown) restricts the continued rotation of the limiting part 6 and achieves mechanical engagement with the limiting part 6, so that the knob 5 can only rotate 180 degrees back and forth. For example, the part marked with arrow 401, the knob protrusion is constructed to allow manual driving of the knob 5; the limiting part 6 is constructed to be a stop on the housing top cover 4 that it mates with in the assembled state; the fixed engagement part 501 is constructed to be fixedly connected to the switching assembly 20 that it mates with in the assembled state. Here, the fixed engagement part 501 is constructed, for example, as a protrusion that matches the shape of the upper end of the insulator 3 of the switching assembly 20. For example, the lower end of the knob 5 has a protrusion, and correspondingly, a groove 301 can be provided on the upper end of the insulator 3 of the switching assembly 20 to achieve mechanical engagement and fixation. In this way, in the assembled state, the knob 5 can be fixedly connected to the insulator 3 of the switching assembly 20 via the fixed fitting part 501, thereby enabling the rotation of the knob to drive the rotation of the switching assembly 20. Furthermore, because the knob has a knob protrusion, it can be manually driven via this protrusion. Moreover, due to the presence of a limiting part, the knob can move in a desired manner, rather than rotating freely without restriction. Preferably, in one embodiment according to this disclosure, the stop part can also be constructed as a stop protrusion or an eccentric limiting frame structure, or other similar configurations.

[0049] Preferably, in one embodiment according to this disclosure, the driving component is configured as: a knob 5, wherein the knob 5 is configured for manual rotation to drive the switching component 20 to rotate around the central axis; or an electric driving component, wherein the electric driving component is configured to receive a control signal to drive the switching component 20 to rotate around the central axis. In this way, the driving component according to this disclosure can be configured as either manually driven or electrically driven according to the needs of a specific application scenario. For example, in application scenarios where personnel have difficulty accessing the site, it is suitable to configure the driving component as electrically driven, thereby enabling remote transmission of control signals to the electric driving component, thereby automating the operation of the switching component 20 and facilitating control; while in some application scenarios where personnel can easily access the site, it is suitable to configure the driving component as a manually driven knob.

[0050] The following is made with the help of Figure 5A , Figure 5B as well as Figure 5C The structure of the switching component 20 based on this disclosure will now be described. Figure 5A A cross-sectional view of the switching component 20 of a switchable RF connector assembly 100 according to an embodiment of the present disclosure is shown in vertical cross-section. Figure 5B A cross-sectional view of the switching component 20 of a switchable RF connector assembly 100 according to an embodiment of the present disclosure is shown in a horizontal cross-section. Figure 5C A perspective view of a switching component 20 of a switchable radio frequency connector assembly 100 according to one embodiment of the present disclosure is shown. Figure 5A , Figure 5B as well as Figure 5C As can be seen from this, the switching component 20 includes: a cam conductor 2, which is configured to rotate about the central axis and selectively select two radio frequency connectors from the radio frequency connectors 7, 8 and 9 for electrical connection; an insulator 3, which is configured to rotate about the central axis; and a fastener 10, which is configured to fix the cam conductor to the insulator.

[0051] In summary, due to the matching method between the RF connector and the switching component 20 and the structure and switching method of the switching component 20 proposed in this disclosure, the entire connection component can achieve stable RF signal transmission during switching, and the target position of the switching component 20 when rotating is relatively clear, that is, the sense of positioning during switching, which makes it convenient for users to select and switch.
