Abstract
Description
Technical Field
[0001] This application relates to the field of wireless communication, and more particularly to a suspended strip, a phase shifter configured with the suspended strip, and a base station. Background Technology
[0002] Suspended striplines are a type of stripline where microstrip lines are placed within a shielded cavity. They are characterized by low loss and ease of assembly, and are widely used in radio frequency (RF) functional devices such as power dividers, couplers, filters, and power conditioners to transmit wireless microwave signals. Under the same electrical length conditions, suspended striplines exhibit lower signal transmission loss and better transmission quality compared to existing microstrip line structures. The electrical length is defined as the ratio of the physical length of the transmission line (stripline) to the wavelength of the transmitted electromagnetic wave.
[0003] However, existing suspended conveyor belts, due to functional requirements, have excessively long extension paths, which can easily lead to a decline in electrical performance. Furthermore, excessively long suspended conveyor belts also increase processing difficulty, transportation, and installation costs, thus limiting the application scenarios of suspended conveyor belts. Summary of the Invention
[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a spliced suspension strip structure, a phase shifter including this spliced suspension strip structure, and a base station, thereby solving the problem of degraded electrical performance caused by excessively long strips. This application specifically includes the following technical solutions:
[0005] In a first aspect, this application relates to a suspended wire, including a cavity and a wire, wherein the wire is located in the cavity and the wire is insulated from the cavity;
[0006] The cable includes a signal processing line, multiple power divider lines, and connectors. One end of the signal processing line is connected to the signal source, and the other end is electrically connected to the multiple power divider lines.
[0007] The multiple power splitter lines include a first power splitter line, which includes a first segment and a second segment that are disconnected from each other. One end of the first segment is electrically connected to the signal processing line, and the second segment is located at the other end of the first segment away from the signal processing line. A connector is located between the first segment and the second segment to realize signal transmission between the first segment and the second segment.
[0008] This application utilizes a suspended wire design to shield the wire by placing its insulation within a cavity. Then, signal processing lines are electrically connected to multiple power divider lines, allowing the signal source to transmit electrical signals to each power divider line.
[0009] This application's suspended strip cable also splices together two broken sections of the first power divider line from multiple power divider lines to achieve the signal transmission function of the first power divider line. Specifically, in the extension direction of the first power divider line, a connector is set between the disconnected first and second sections. Through the cooperation of the connector with the first and second sections respectively, the transmission of electrical signals on the first power divider line is realized. That is, the electrical signals transmitted from the signal processing line on the first section are transmitted to the second section through the connector to continue propagating to the rear end, so that the strip cable in this application can be disconnected while achieving its function. The aspect ratio of each disconnected strip cable is smaller than that of the overall extended strip cable, which is beneficial for manufacturing and maintaining the consistency of the strip cable. At the same time, the disconnected strip cables can also be assembled later to form a complete suspended strip cable structure, which reduces the processing difficulty of the suspended strip cable in this application and facilitates the transportation and installation of the suspended strip cable.
[0010] In one possible implementation, the connector is conductive and includes a connecting segment, a first pin, and a second pin. The first pin and the second pin are located at opposite ends of the connecting segment. The first pin is fixed relative to the first segment, and the second pin is fixed relative to the second segment. The first pin and the second pin respectively enable signal transmission between the first segment and the second segment through conduction or coupling.
[0011] In this implementation, the first pin of the connector is fixed relative to the first segment, and the second pin, opposite to the first pin, is fixed relative to the second segment. This allows the two pins of the connector to transmit signals between themselves and the first segment, and between themselves and the second segment, respectively. Then, the connecting segment between the first and second pins conducts the signal, enabling the electrical signal transmitted on the first segment to be transmitted sequentially through the first pin, the connecting segment, and the second pin to the second segment, and then continue to be transmitted towards the rear end of the second segment.
[0012] In one possible implementation, the line width of the connecting segment is less than or equal to the line width of the first segment and the line width of the second segment.
[0013] In this implementation, the line width of the connecting segment is set to be less than or equal to the line width of the first segment, and simultaneously less than or equal to the line width of the second segment. This allows the connector to achieve impedance matching with the first and second segments respectively during signal transmission, thereby reducing signal loss caused by the connector.
[0014] In one possible implementation, the first pin is soldered to the first segment for electrical connection, and the second pin is also soldered to the second segment for electrical connection.
[0015] In this implementation, the connector is connected to the first and second segments by welding to achieve signal transmission.
[0016] In one possible implementation, the length of the connecting segment is greater than the straight-line distance between the first and second feet.
[0017] In this implementation, the connecting segment is curved or zigzag-shaped, or includes curved or zigzag segments. Therefore, when the connecting component is welded to the first and second segments respectively, the deformation of the connecting segment can compensate for the thermal stress deformation that the connecting component may experience, ensuring a fixed connection between the connecting segment and the first and second segments respectively.
[0018] In one possible implementation, an isolation pad is sandwiched between the first segment and the connector, and an isolation pad is also sandwiched between the second end and the connector. Signal transmission is achieved through coupling between the first segment and the connector, and between the second segment and the connector.
[0019] In this implementation, the connector is fixed to the first segment via an isolation pad, achieving coupling; the connector is also fixed to the second segment via an isolation pad, similarly achieving coupling. The electrical signal on the first segment is transmitted to the second segment after being coupled twice by the connector, realizing its function of transmission towards the rear end of the second segment.
[0020] In one possible implementation, the suspended strip also includes a first substrate and a second substrate that are relatively fixed. Both the first substrate and the second substrate are substrates of a printed circuit board. The signal processing line and the first segment are located on the first substrate, and the second segment is located on the second substrate.
[0021] In this implementation, the first power divider line is fabricated on the first substrate and the second substrate respectively, forming a printed circuit line structure. The mutual fixing between the first substrate and the second substrate achieves mutual fixing between the first segment and the second segment, and the signal transmission function between the first segment and the second segment is realized by the connector.
[0022] In one possible implementation, the first segment includes a first extension segment located at the end of the first segment away from the signal processing line; the second segment includes a second extension segment located at the end of the second segment close to the first segment.
[0023] The connector is insulated and is located on one side of the first power divider line. The connector is used to fix the first extension section and the second extension section and to realize signal transmission between the first extension section and the second extension section.
[0024] In this implementation, the connector fixes the first extension segment and the second extension segment, thereby fixing their relative positions and enabling the transmission of electrical signals from the first segment to the second segment through the cooperation of the first extension segment and the second extension segment.
[0025] In one possible implementation, the first extension segment and the second extension segment extend along a first direction, and the first direction forms an angle with the extension direction of the first segment.
[0026] In this implementation, the first extension segment and the second extension segment extend in the same direction, and the first direction is different from the extension direction of the first segment, and naturally also different from the extension direction of the second segment. That is, the first extension segment bends relative to the first segment, and the second extension segment also bends relative to the second segment, which makes it easier for the connector to fix the position of the first extension segment and the second extension segment, and to compress the spatial area of the first power dividing line.
[0027] In one possible implementation, the angle between the first direction and the extension direction of the first segment is 90 degrees.
[0028] In this implementation, the extension direction of the first segment and the extension direction of the second segment are usually continuous in the same direction. If the first direction is set to form a 90-degree angle with the continuous direction, then both the first extension segment and the second extension segment bend perpendicular to the direction. This is beneficial for the connector to fix the first extension segment and the second extension segment at the same time, and to maintain the consistency of signal transmission between the first extension segment and the first segment, as well as between the second extension segment and the second segment.
[0029] In one possible implementation, the connector includes a body and a first through hole and a second through hole formed on the body. The body is fixedly connected to a first power distribution line. The first through hole is used to accommodate a first extension section, and the second through hole is used to accommodate a second extension section.
[0030] In this embodiment, the connector positions the first extension segment through the first through hole and the second extension segment through the second through hole, which can effectively hold the first extension segment and the second extension segment respectively, ensuring the cooperative transmission function between the first extension segment and the second extension segment.
[0031] In one possible implementation, the first extension segment includes a first connecting end extending out of the first through hole, and the second extension segment includes a second connecting end extending out of the second through hole. The first connecting end and the second connecting end achieve signal transmission between the first segment and the second segment by means of conduction or coupling.
[0032] In this implementation, the first connecting end and the second connecting end extend out of the first through hole and the second through hole, respectively. During the mating process, no interference from other media is introduced between the first connecting end and the second connecting end, which is beneficial to achieving impedance matching between the first extension section and the second extension section.
[0033] In one possible implementation, the first connecting end and the second connecting end are connected by welding. The body also has a receiving cavity located on the side of the first through hole away from the first segment. The receiving cavity connects the first through hole and the second through hole and is used to receive the first connecting end and the second connecting end.
[0034] In this implementation, welding the first and second connecting ends together enables the transmission of electrical signals. The receiving cavity is located on the side away from the first segment, corresponding to the first and second connecting ends. The receiving cavity protects the first and second connecting ends and also serves to contain the solder formed between them.
[0035] In one possible implementation, the first connection end and the second connection end are coupled to achieve signal transmission, the first segment is formed on the first plane, and the first direction is perpendicular to the first plane.
[0036] In this implementation, since the first segment is formed on the first plane, its linewidth also extends along the first plane. With the first direction perpendicular to the first plane, after the first extension segment bends relative to the first segment, its linewidth direction is directly opposite the second extension segment. Correspondingly, when the second extension segment bends along the first direction, it also bends with its linewidth direction directly opposite the first extension segment. Therefore, during the coupling process between the first and second connecting ends, the relative area of interaction is larger, resulting in better coupling and ensuring signal transmission.
[0037] In one possible implementation, the distance between the first connecting end and the second connecting end is less than or equal to 0.5 mm and greater than or equal to 0.1 mm.
[0038] In this implementation, controlling the relative distance between the first connection terminal and the second connection terminal can ensure the capacitance value between the first connection terminal and the second connection terminal, thereby reducing the signal loss when the first connection terminal and the second connection terminal are coupled.
[0039] In one possible implementation, the line width of the first extension segment is less than or equal to the line width of the first segment and the line width of the second segment; and,
[0040] The line width of the second extension segment is less than or equal to the line width of the first segment and the line width of the second segment.
[0041] In this implementation, the line width of the first extension segment is set to be less than or equal to the line width of the first segment, and simultaneously less than or equal to the line width of the second segment; at the same time, the line width of the second extension segment is also less than or equal to the line width of the first segment, and simultaneously less than or equal to the line width of the second segment, so that the first extension segment and the second extension segment can achieve impedance matching with the first segment and the second segment respectively during signal transmission, thereby reducing the signal loss caused by the connector.
[0042] In one possible implementation, the stripline also includes a signal processing port and multiple signal transceiver ports. The end of the signal processing line away from the multiple power divider lines is connected to the signal processing port. The number of multiple signal transceiver ports is the same as the number of multiple power divider lines. The end of each power divider line away from the signal processing line is connected to a signal transceiver port.
[0043] In this implementation, the signal processing line is connected to the signal processing port to receive the signal source. Each power divider line outputs a signal to the back end through its own connected signal transceiver port, realizing the phase distribution function of the suspended stripline.
[0044] Secondly, this application provides a phase shifter, including the suspension cable as described above.
[0045] It is understandable that the phase shifter involved in this application, because it includes the aforementioned suspension wire, also possesses the characteristics of the aforementioned suspension wire, such as being easy to manufacture and maintain consistency, having low processing difficulty, and being easy to transport and install.
[0046] In one possible implementation, the phase shifter further includes a sliding medium housed within the cavity and capable of sliding relative to the cavity. The sliding medium engages with each power divider line, and by sliding, changes the electrical length of each power divider line to achieve phase adjustment.
[0047] Thirdly, this application provides a base station including the phase shifter described above.
[0048] Understandably, the base station in this application, because it includes the aforementioned phase shifter, also possesses the characteristics of having a suspended cable that facilitates manufacturing and maintains consistency, has lower processing difficulty, and is easy to transport and install, just like the aforementioned phase shifter.
[0049] In one possible implementation, the base station further includes a baseband processing unit, a radio frequency remote unit, and an antenna feeder system, wherein the phase shifter is located in the antenna feeder system. The radio frequency remote unit is connected between the baseband processing unit and the antenna feeder system, and the antenna feeder system is connected to the baseband processing unit through the radio frequency remote unit to realize the function of transmitting and receiving wireless signals.

[0072] The technical solutions of the embodiments of this application will now be described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0073] The base station involved in this application may include a baseband processing unit, a radio frequency processing unit, and... Figure 1 The antenna feed system 500 is shown. An RF processing unit is connected between the baseband processing unit and the antenna feed system 500. There can be multiple antenna feed systems 500, and the same number of RF processing units. Each antenna feed system 500 cooperates with one RF processing unit. Multiple antenna feed systems 500 are each connected to a baseband processing unit through their corresponding RF processing unit to achieve wireless signal transmission and reception. In one embodiment, the RF processing unit can be integrated with the antenna; in another embodiment, the RF processing unit is independently configured.
[0074] Please see Figure 1 The diagram shows the structure of the antenna feeder system 500. The antenna feeder system 500 includes an antenna assembly 400, a mast 502, an antenna bracket 503, a connector seal 504, and a grounding device 501. The mast 502 is fixed relative to the ground, and the antenna bracket 503 connects the antenna assembly 400 and the mast 502, providing a fixed connection between them. In some embodiments, the antenna bracket 503 can also be configured as an adjustable bracket, used to adjust the azimuth and angle of the antenna assembly 400 relative to the mast 502, thereby coordinating with the signal transmission angle of the antenna assembly 400 to ensure that the signal emitted by the antenna feeder system 500 forms a preset downtilt angle with the ground. The antenna feeder system 500 of this application can be installed in any public place or residential area to achieve signal coverage in its corresponding area.
[0075] The antenna assembly 400 is also electrically connected to a grounding device 501 to enable grounding of the antenna assembly 400. The end of the grounding device 501 furthest from the antenna assembly 400 can also be connected and fixed to a mast 502, achieving grounding through the mast 502. Understandably, the grounding device 501 can also be directly fixed to the ground to ensure reliable grounding of the antenna assembly 400. The antenna assembly 400 is typically housed in a sealed enclosure (radome). This enclosure needs to possess sufficient mechanical strength and resistance to contamination and water to protect the internal components of the antenna assembly 400 from external environmental influences. Electrically, the enclosure needs to have good electromagnetic wave penetration characteristics to ensure the signal transmission and reception functions of the antenna assembly 400. A connector seal 504 can also be provided between the grounding device 501 and the enclosure of the antenna assembly 400. When the grounding device 501 is led out from the antenna assembly 400, it can achieve a sealed connection between itself and the housing of the antenna assembly 400 through the connector seal 504, thereby achieving sealed protection of each component inside the housing of the antenna assembly 400.
[0076] Please see Figure 2 The diagram shows the internal architecture of the antenna assembly 400 in the antenna feed system 500 of this application. Inside the housing of the antenna assembly 400, one or more radiating elements 401, a metal reflector 402, and a phase shifter 403 are disposed. The radiating elements 401 are located on one side of the metal reflector 402 and form at least one independent array with the metal reflector 402. The radiating elements 401 may include antenna elements (also called vibrators) for transmitting or receiving radio waves. The frequencies of the radiating elements 401 in the independent array can be the same or different, thus corresponding to the transmission and reception of radio waves in different frequency bands. When the metal reflector 402 is located on one side of the radiating elements 402, it is used to reflect the radio signal and concentrate the radio signal on the radiating elements 401 to enhance the radio signal received by the radiating elements 401; the metal reflector 402 is also used to reflect and transmit the radio signal at the radiating elements 401 outwards to enhance the signal strength emitted by the radiating elements 401. Furthermore, the metal reflector 402 is also used to block or shield wireless signals from the other side (i.e., the opposite direction) of the radiating unit 401, so as to prevent the wireless signals from the other side from interfering with the radiating unit 401.
[0077] Phase shifter 403 is electrically connected to radiating unit 401. The side of phase shifter 403 facing away from radiating unit 401 is also connected to antenna interface 406, and through antenna interface 406, to baseband processing unit of base station. Baseband processing unit can be used to generate signals, which, after phase distribution by phase shifter 403, are transmitted to radiating unit 401 for external transmission; or, baseband processing unit can be used to receive wireless signals transmitted by radiating unit 401, and these wireless signals are processed by phase shifter 403 according to a certain phase. In this application, phase shifter 403 is used to adjust the phase of wireless signals, thereby changing the downtilt angle of the wireless signal beam and optimizing the communication network. Furthermore, antenna assembly 400 may also include a transmission or calibration network 404, and a combiner or filter 405, etc., for operations such as calibrating wireless signals and adjusting the amplitude of wireless signals.
[0078] Please see Figure 3 The diagram shows the internal structure of the phase shifter 403 of this application. The phase shifter 403 may include a suspended strip line 300 and a sliding medium 301. The sliding medium 301 can slide relative to the suspended strip line 300, thereby adjusting the phase of the electrical signal in the phase shifter 403 by changing the electrical length of the suspended strip line 300, i.e., the ratio of the physical length of the transmission line to the transmitted wavelength. In this application's phase shifter 403, the suspended strip line 300 can be used to implement the function of a power divider. That is, the sliding medium 301 slides relative to the power divider composed of the suspended strip line 300 to change the phase output of the phase shifter 403. It is understood that in other embodiments, the suspended strip line 300 provided in this application can also be used in other wireless communication devices, such as couplers, voltage regulators, or filters, to implement functions such as microwave wireless signal transmission and / or phase adjustment. In this application specification, for the convenience of describing the various embodiments, the suspended strip 300 is used as the power divider in the phase shifter 403 to introduce the various implementation methods.
[0079] Please continue reading Figure 3 and simultaneously combined Figure 4 The schematic top view of the internal structure of the phase shifter 403 of this application shows that the suspension wire 300 includes a cavity 200 and Figure 3 The strip 100 is shown. The strip 100 is located within the cavity 200 and fixed relative to the cavity 200. The strip 100 is also insulated from the cavity 200. In one embodiment, the strip 100 is entirely housed within the cavity 200. Figure 4 It can be seen that the strip 100 extends mainly along the second direction 002 within the cavity 200, and the second direction 002 can also be defined as the main extension direction of the strip 100.
[0080] The cavity 200 has electromagnetic shielding properties, serving as a grounding structure for the strip 100 and simultaneously shielding against external signal interference, ensuring the transmission of electrical signals through the strip 100. In one embodiment, the cavity 200 can be a completely sealed structure, with the strip 100 housed within it, achieving better shielding. In other embodiments, the cavity 200 can be as follows: Figure 3 and Figure 4 The diagram shows a through-hole 204. Specifically, in... Figure 3 and Figure 4 In the schematic cavity 200, the cavity 200 has an upper surface 201 and a lower surface 202 disposed opposite to each other, and a side surface 203 connecting the upper surface 201 and the lower surface 202. There are two side surfaces 203, which are also located on opposite sides of the strip 100. The upper surface 201, the lower surface 202, and the two side surfaces 203 all extend along the second direction 002. In the length extension direction of the strip 100 (second direction 002), the cavity 200 has a structure with through holes 204 at both ends. That is, the cavity 200 forms a through structure in the direction along the length extension direction of the strip 100 (second direction 002), and the through holes 204 penetrate the cavity 200 along the second direction 002. Both types of cavity 200 can provide reliable shielding for the wire 100. The cavity 200 with through hole 204 is also easy to manufacture using molding processes such as extrusion and casting, and is also convenient for assembling the wire 100 in the cavity 200.
[0081] The sliding medium 301 is slidably connected within the cavity 200 and located on one side of the wire 100. Figure 3 and Figure 4 In the schematic diagram, the sliding medium 301 is located vertically above the strip 100. The sliding medium 301 can slide relative to the cavity 200 and adjust its relative position with respect to the strip 100. Different relative positions of the sliding medium 301 and the strip 100 will cause a corresponding change in the equivalent dielectric constant of the strip 100, that is, the sliding of the sliding medium 301 relative to the strip 100 can change the electrical length of the strip 100, thereby changing the phase output of the strip 100. In one embodiment, the sliding medium 301 slides relative to the strip 100 along the extension direction (second direction 002) of the strip 100 to create a larger range of phase shift effect on the strip 100.
[0082] Please continue reading Figure 4 The line 100 includes a signal processing line 130 and at least two power dividing lines. Figure 4In the illustration, at least two power divider lines include a first power divider line 110 and a second power divider line 120. The stripline 100 also includes a signal processing port 101 and a signal transceiver port 102. There are multiple signal transceiver ports 102, and each power divider line is connected to one signal transceiver port 102. Figure 4 In the diagram, the first power divider line 110 is connected to the first signal transceiver port 1021, and the second power divider line 120 is connected to the second signal transceiver port 1022.
[0083] One end of the signal processing line 130 is connected to the signal processing port 101. The signal processing line 130 receives signals from the baseband processing unit or transmits signals output by the baseband processing unit through the signal processing port 101. In this case, the baseband processing unit can be understood as a signal source. In this embodiment, the signal processing port 101 and the signal transceiver port 102 can be independent interface structures. The signal processing port 101 can also be defined as one end of the signal processing line 130, and the signal transceiver port 102 can also be defined as one end of the power divider line. It is understood that notches (not shown in the figure) corresponding to the positions of the signal processing port 101 and the signal transceiver port 102 can also be provided on the cavity 200 to realize signal transmission between the suspended cable and the outside.
[0084] The end of signal processing line 130 furthest from signal processing port 101 is connected to multiple power divider lines. Figure 4 In the illustration, the end of signal processing line 130 furthest from signal processing port 101 is connected to the first power divider line 110 and the second power divider line 120, respectively. It is understood that when the ribbon cable 100 includes two or more power divider lines, all of these power divider lines need to be connected to signal processing line 130. At the locations where signal processing line 130 is connected to the first power divider line 110 and the second power divider line 120, the signals emitted by signal processing line 130 can be transmitted to the first power divider line 110 and the second power divider line 120, respectively, and the signals received by signal processing line 130 can also be obtained through the first power divider line 110 and the second power divider line 120, respectively. The locations where signal processing line 130 connects to the first power divider line 110 and the second power divider line 120 are called power divider sections.
[0085] Because the lengths of the first power divider line 110 and the second power divider line 120 are different, their impedances also differ. When an electrical signal is fed into the suspended stripline 300 from the signal processing port 101, it is first transmitted to the power divider section via the signal processing line 130. Then, the electrical signal is transmitted to the first signal transceiver port 1021 and the second signal transceiver port 1022 via the first power divider line 110 and the second power divider line 120, respectively. Furthermore, due to the difference in the equivalent dielectric constant between the first power divider line 110 and the second power divider line 120, a phase difference is formed between the electrical signal at the first signal transceiver port 1021 and the second signal transceiver port 1022, thereby adjusting the output phase distribution of the electrical signal.
[0086] In the phase shifter 300 of this application, the sliding medium 301 also simultaneously covers the first power divider line 110 and the second power divider line 120. As mentioned above, both the first power divider line 110 and the second power divider line 120 extend mainly along the second direction 002. Therefore, the sliding medium 301 can simultaneously cover the first power divider line 110 and the second power divider line 120 along the second direction 002. At this time, as the sliding medium 301 slides relative to the cavity 200, the lengths of the sliding medium 301 covering the first power divider line 110 and the second power divider line 120 also change synchronously. The equivalent dielectric constant of the portion of the first power divider line 110 covered by the sliding medium 301 will change, and the equivalent dielectric constant of the portion of the second power divider line 120 covered by the sliding medium 301 will also change. Therefore, when the sliding medium 301 slides relative to the cavity 200, the areas of the first power divider line 110 and the second power divider line 120 it covers change synchronously. That is, the equivalent dielectric constants of the first power divider line 110 and the second power divider line 120 change synchronously under the sliding action of the sliding medium 301. As a result, the electrical length from the power divider section to the first signal transceiver port 1021 and the electrical length from the power divider section to the second signal transceiver port 1022 are also adjusted accordingly. The phase shifter 400 of this application can change the phase angle difference between the first transceiver port 1021 and the second transceiver port 1022 by sliding the sliding medium 301, thereby achieving the function of adjusting the phase of the electrical signal.
[0087] Understandably, when electrical signals are input from the first transceiver port 1021 and the second transceiver port 1022 and transmitted to the signal processing port 101, the electrical signals obtained by the signal processing port 101 will also undergo phase adjustment due to the difference in electrical length between the first power divider line 110 and the second power divider line 120.
[0088] When there are multiple power divider lines in the 100-line circuit, the sliding medium can simultaneously cover multiple power divider lines and slide synchronously relative to multiple power divider lines to synchronously change the electrical length of multiple power divider lines, thereby realizing phase distribution functions at more angles.
[0089] In existing suspended stripline structures, the requirement for phase adjustment functionality typically necessitates the fabrication of transmission lines with long extension paths, resulting in some lines exceeding 1000 millimeters (mm) in length. However, the linewidth of existing transmission lines is usually maintained between 2mm and 3mm, leading to a relatively large aspect ratio, increased manufacturing difficulty, and challenges in maintaining linewidth consistency along the extension path. Linewidth consistency refers to the shape difference between any two cross-sections of the transmission line along its extension direction. The smaller the shape difference between the two cross-sections, the higher the linewidth consistency. Understandably, shorter transmission line extension paths facilitate better control of linewidth consistency. The large length of existing transmission lines results in poor linewidth consistency, leading to changes in the equivalent dielectric constant. This, in turn, causes signal mismatch, reflection loss, and other adverse phenomena, making it difficult to adjust signal phase deviation. Furthermore, the long transmission lines also result in excessively large dimensions for existing suspended striplines, hindering their transportation and installation.
[0090] It should be noted that in the embodiments of this specification, the suspended stripline 300 is used as a power divider in the phase shifter 403; therefore, the transmission lines in the stripline 300 are defined as power dividing lines, also known as power branch lines. However, when the suspended stripline 300 is used as a component in a coupler, the transmission line can be defined as a coupling line; or when the suspended stripline 300 is used as a filter, the transmission line can be defined as a filter line or filter stub. Based on different specific functions, the naming of the transmission lines in the suspended stripline 300 of this application may vary slightly.
[0091] Please see Figure 4a The diagram shows a partial structural representation of the line 100 in the phase shifter 403, in conjunction with reference to [reference needed]. Figure 5 The specific structure of the suspended stripline 300 shown is as follows. In the suspended stripline 300 of this application, the first power divider line 110 among multiple power divider lines is broken into a first segment 10 and a second segment 20 along its extension direction. The first segment 10 is located near the power divider section, and the second segment 20 is located near the first signal transceiver port 1021. That is, the first segment 10 includes a first end 11 and a second end 12, with the first end 11 connected to the signal processing line 130, and the second end 12 located away from the signal processing line 130 along the extension direction of the first power divider line 110, and the second end 12 is close to the second segment 20; the second segment 20 also includes a third end 21 and a fourth end 22, with the fourth end 22 located at the first signal transceiver port 1021, and the third end 21 located near the first segment 10, and also near the second end 12. The first segment 10 and the second segment 20 of the first power divider line 110 are disconnected from each other.
[0092] The cable 100 also includes a connector 30, which is located between the first segment 10 and the second segment 20. The connector 30 is fixed relative to both the first segment 10 and the second segment 20 and is used to realize the signal transmission function between the first segment 10 and the second segment 20. For details, please refer to [reference needed]. Figure 4 , Figure 4a and Figure 5 The first power splitter line 110 is split into a first segment 10 and a second segment 20 that are spaced apart from each other. For example, an electrical signal is input from the signal processing port 101 and, after being transmitted on the first power splitter line 110, reaches the second end 12. Through the action of the connectors 30 that are fixed relative to the first segment 10 and the second segment 20 respectively, the signal at the second end 12 is transmitted to the third end 21, and the signal is further transmitted to the first signal transceiver port 1021 via the second segment 20, thus realizing the transmission function of the electrical signal on the entire first power splitter line 110.
[0093] The suspended strip line 300 of this application, by disconnecting the first power divider line 110, which corresponds to the existing transmission line, into two independent segments, a first segment 10 and a second segment 20, and using a connector 30 to achieve signal transmission between the first segment 10 and the second segment 20, allows the first segment 10 and the second segment 20 to be manufactured separately, with their respective aspect ratios controlled, thereby improving the consistency of the first segment 10 and the second segment 20, and thus ensuring the overall consistency of the first power divider line 110. Simultaneously, the first segment 10 and the second segment 20 can also be transported separately. During installation, there is no need to manipulate the large suspended strip line; instead, the disconnected first segment 10 and the second segment 20 are spliced together and assembled, and the signal transmission function between them is achieved using the connector 300 to form the first power divider line 110. This configuration also reduces the transportation and installation costs of the suspended strip line 300. It is understood that the phase shifter 403 of this application, and the base station involved in this application, have achieved better signal transmission consistency and reduced transportation and installation costs due to the configuration of the suspended strip line 300 of this application. When the suspended strip 300 of this application is used as a coupler, power conditioner or filter, the coupler, power conditioner and filter equipped with the suspended strip 300 of this application also have better signal transmission capabilities and lower transportation and installation costs.
[0094] It is understood that this application does not limit the specific number of power divider lines that are disconnected from each other in the multiple power divider lines in the strip 100. That is, based on the specific length and operating requirements of each power divider line in the strip 100, the number of lines that are disconnected into two relative segments can be multiple, or even all of the multiple power divider lines can be set to be disconnected into two relative segments, and each can realize the signal transmission function between the disconnected lines through its corresponding connector 30. This application only illustrates an embodiment in which one of the multiple power divider lines has a disconnected structure.
[0095] The first power divider 110 can be further divided into three mutually disconnected segments, namely, the first power divider 110 is broken into a first segment 10, a second segment 20, and a third segment (not shown in the figure). The third segment is also disconnected from the second segment 20, and is located at the end of the second segment 20 furthest from the first segment 10. In this case, the third segment includes an end closer to the second segment 20 and an end farther from the second segment 20, and the end of the third segment furthest from the second segment 20 is connected to the first signal transceiver port 1021. Signal transmission can also be achieved between the second segment 20 and the third segment through the connector 30. Furthermore, the first power divider 110 can be divided into even more mutually disconnected segments, which can be specifically set based on the length of the first power divider 110 and the actual operating requirements. Because of the signal transmission function of the connector 30 of this application, the suspended cable 300 of this application can arbitrarily set the number of disconnected power dividers and the number of segments into which each power divider is broken, ensuring the functional realization of the suspended cable 300 of this application.
[0096] Please see Figure 6 One implementation of the connector 30 shown. Figure 6 In the illustration, assume the first power divider line 110 (in Figure 6 In this embodiment, the first segment 10 and the second segment 20 are located on the first plane 111, and both the first segment 10 and the second segment 20 extend on the first plane 111. That is, the second direction 002 is located within the first plane 111, and the signal processing line 130 and the remaining power distribution line are also located within the first plane 111. In this embodiment, the connector 30 is constructed as a bridging jumper 31. The jumper 31 is conductive and includes a connecting segment 313, a first pin 311, and a second pin 312. The first pin 311 and the second pin 312 are located at opposite ends of the connecting segment 313, that is, the connecting segment 313 connects the first pin 311 and the second pin 312. The length direction of the connecting segment 313 is arranged along the extension direction of the first power distribution line 110, and the first pin 311 is located near the first segment 10, and the second pin 312 is located near the second segment 20. The connecting segment 313 is located outside the first plane 111 and is spaced apart from the first power divider line 110. The connecting segment 313 is fixedly connected to and conductively connected to the first segment 10 via the first pin 311; the connecting segment 313 is also fixedly connected to and conductively connected to the second segment 20 via the second pin 312. It is understood that the first pin 311 can be relatively fixed and conductively connected to the first segment 10 by welding, and the second pin 312 can also be relatively fixed and conductively connected to the second segment 20 by welding.
[0097] Therefore, the electrical signal input from the first end 11 of the first segment 10, after reaching the second end 12, can be transmitted through the first pin 311 to the connecting segment 313, and then through the connecting segment 313 to the second pin 312. From the second pin 312, it is transmitted to the third end 21 of the second segment 20, allowing the signal to continue along the second end 20 to the fourth end 22, and finally output from the first signal transceiver port 1021. Conversely, when the electrical signal is input from the first signal transceiver port 1021, it can be transmitted sequentially through the second segment 20 to the second pin 312, the connecting segment 313, the first pin 311, and the first segment 10, and finally transmitted to the signal processing line 130 through the power divider. The bridging jumper 31, by connecting to the first segment 10 and the second segment 20 respectively, achieves the effect of transmitting the electrical signal between the first segment 10 and the second segment 20.
[0098] Understandable, Figure 6 In this embodiment, the connection position between the first leg 311 and the first segment 10 can be located near the position of the second end 12. In addition to welding, the first leg 311 and the first segment 10 can also be connected by snap-fitting, adhesive or other methods. As long as reliable contact between the first leg 311 and the first segment 10 is ensured, the conductivity between the first leg 311 and the first segment 10 can be guaranteed. Correspondingly, the connection position between the second leg 312 and the second segment 20 can also be located near the third end 21. The second leg 312 and the second segment 20 can also be connected by snap-fitting, adhesive or other methods to realize the signal transmission function of the connector 30.
[0099] In one embodiment, please refer to Figure 6a Furthermore, the linewidth d of the connecting segment 313 can be set to be less than or equal to the linewidth D1 of the first segment 10, and simultaneously less than or equal to the linewidth D2 of the second segment 10. As mentioned above, in order to meet the requirement of consistent equivalent dielectric constant of the strip 100, the linewidth of the first power divider 110 perpendicular to the extension path along the path of the first power divider 110 tends to be consistent, that is, the linewidth D1 of the first segment 10 and the linewidth D2 of the second segment 20 should preferably be set to be equal. However, when the jumper 31 is connected between the first segment 10 and the second segment 20, its structural characteristics cause the equivalent dielectric constant of the jumper 31 to be slightly greater than the equivalent dielectric constant of the first segment 10 and the second segment 20. Therefore, setting the line width d of the connecting segment 313 of the jumper 31 to be less than or equal to the line width D1 of the first segment 10 and the line width D2 of the second segment 20 is beneficial to control the impedance matching between the jumper 31 and the first segment 10 and the second segment 20, thereby reducing the loss at the jumper 31 and improving the overall electrical performance of the first power divider line 110.
[0100] Please see Figure 7Another embodiment of the jumper 31 shown is in Figure 7 In the illustration, the connecting section 313 of the jumper 31 also has a curved section 3131. The curved section 3131 bends along the extension path from the first leg 311 to the second leg 312, so that the overall length of the jumper connecting section is greater than the straight-line distance between the first leg 311 and the second leg 312. When the jumper 31 is bridged between the first section 10 and the second section 20, if it is fixed by welding, thermal stress will be formed on the jumper 31, and the jumper 31 may deform as a result. At this time, because the connecting section 313 has a curved section 3131, the jumper 31 can compensate for the deformation caused by thermal stress through the deformation of the curved section 3131, ensuring that the connecting section 313 maintains a sufficient length between the first leg 311 and the second leg 312, and avoiding defects such as cracks or even breakage of the connecting section 313 due to thermal stress deformation.
[0101] Figure 8 Another implementation of the connector 30 is illustrated. In this implementation, the connector 30 is constructed as a patch 32 for signal transmission via coupling. Specifically, the patch 32 includes a first coupling end 321 and a second coupling end 322, and a connecting piece 323 connecting the first coupling end 321 and the second coupling end 322. The patch 32 is separated from both the first segment 10 and the second segment 20, and the patch 32 is also separated from the first power divider line 110 (in... Figure 8 The isolation pad 324 is sandwiched between the first segment 10 and the second segment 20. The isolation pad 324 is an insulating material and can be injection molded. The isolation pad 324 is used to achieve insulation and fixation between the patch 32 and the first power distribution line 110, so as to achieve the effect of signal transmission by coupling between the patch 32 and the first segment 10 and the second segment 20 respectively.
[0102] Specifically, there are two isolation pads 324, located between the first coupling end 321 and the first segment 10, and between the second coupling segment 322 and the second segment 20, respectively. The first coupling end 321 and the second end 12 of the first segment 10 are spaced apart, and the isolation pads 324 are used to fix and support the first coupling end 321. The first power divider line 110 is also located within the first plane 111. At this time, the two isolation pads 324 are located at the second end 12 and the third end 21, respectively. The first coupling end 321 is fixedly connected to the isolation pad 324 located at the second end 12, and the projection of the first coupling end 321 on the first plane 111 at least partially overlaps with the second end 12. Thus, the second end 12 and the first coupling end 321 can form a capacitor, and transmit the electrical signal on the first segment 10 to the first coupling end 321 through coupling.
[0103] The first coupling end 321 transmits the electrical signal to the second coupling end 322 via the connecting piece 323. Similarly, an isolation pad 324 is provided between the second coupling end 322 and the third end 21, and the projection of the second coupling end 322 on the first plane 111 at least partially overlaps with the third segment 21. Thus, the second coupling end 322 can transmit the electrical signal to the third end 21 through coupling, and further transmit the electrical signal via the second segment 20. It can be understood that when the electrical signal is input from the second segment 20, it can also be transmitted from the second segment 20 to the first segment 10 via the patch 32 through two couplings.
[0104] Understandably, the implementation of patch 32 is similar to that of jumper 31. Some embodiments of jumper 31 can also be applied to patch 32 to improve the signal transmission effect of connector 30. That is, the line width of connector 323 (not shown in the figure) can be less than or equal to the line width D1 of the first segment 10 and the line width D2 of the second segment 20, and connector 323 can also be provided with a bent portion to compensate for the thermal stress deformation that may be formed when patch 32 is heat-bonded to insulating pad 324 by injection molding or other methods.
[0105] The strip 100 in the above embodiments is based on the structure of sheet metal strip. In other embodiments, the strip may also be a PCB strip fabricated on a printed circuit board substrate, or other types of strip.
[0106] Please see Figure 9 and Figure 10 This illustrates another implementation method. (The remaining text appears to be incomplete and possibly contains errors.) Figure 9 This is a schematic diagram of the internal structure of a PCB with traces. Figure 10 This is a top view of the internal structure of the PCB trace. The suspended trace 300 also includes a first substrate 310 and a second substrate 320. Both the first substrate 310 and the second substrate 320 are fixed within the cavity 200 and are fixed relative to each other. The first substrate 310 and the second substrate 320 are arranged side by side along the second direction 002. Both the first substrate 310 and the second substrate 320 are substrates for a printed circuit board (PCB). The signal processing line 130, the second power divider line 120, and the first segment 10 are all located on the first substrate 310, while the second segment 320 is located on the second substrate 320. The connector 30 is located between the first substrate 310 and the second substrate 320. Thus, the trace 100 is constructed as a PCB trace.
[0107] In this implementation, the first substrate 310 has a first outer surface 3101, on which the signal processing line 130, the second power divider line 120, and the first segment 10 are all located. Since the strip 100 is constructed as a PCB strip, the signal processing line 130, the second power divider line 120, and the first segment 10 can all be printed on the first outer surface 3101, with the bottom of each line contacting and aligning with the first outer surface 3101. It is understood that the second substrate 320 includes a second outer surface 3201, and the second outer surface 3201 and the first outer surface 3101 have the same orientation. When the second segment 20 is located on the second substrate 320, the second segment 20 can also be printed on the second outer surface 3201, and the bottom surface of the second segment 20 is flush with the second outer surface 3201.
[0108] In other embodiments, grooves (not shown) may be correspondingly formed on the first substrate 310 and the second substrate 320. These grooves are used to accommodate each line of the strip 100, such that each line of the strip 100 is at least partially accommodated in the groove. In this case, the bottom surface of the strip 100 will be lower than the first outer surface 3101 and the second outer surface 3201. In some embodiments, when the strip 100 is completely accommodated in the groove, the top surface of the strip 100 may also be flush with the first outer surface 3101 and the second outer surface 3201. These embodiments are all possible implementations of PCB board strips, and also belong to one implementation of the strip 100 located on the first substrate 310 and the second substrate 320 in this application.
[0109] The first substrate 310 and the second substrate 320 can provide reliable support for the strip 100. The strip 100 can also be fixed in position relative to the cavity 200 by fixing the first substrate 310 and the second substrate 320 relative to the cavity 200. After the first segment 10 of the first power divider 110 is disposed on the first substrate 310 and the second segment 20 is disposed on the second substrate 320, the first power divider 110 is disposed on two independent substrates. The connection 30 structure described above can also be used between the second end 12 of the first segment 10 and the third end 21 of the second segment 20 to realize the signal transmission function.
[0110] Specifically, in Figure 9 In the schematic diagram, connector 30 is configured as jumper 31, which is soldered to the first segment 10 and the second segment 20 respectively to achieve signal transmission. Figure 10 In the illustration, the connector 30 is set as a patch 32. The patch 32 transmits signals with the first segment 10 and the second segment 20 respectively through coupling, and also realizes the effect of the first power splitter 110 transmitting signals.
[0111] Both the second power divider line 120 and the signal processing line 130 are located on the first substrate 310, enabling electrical conduction between the signal processing line 130 and the first segment 10 and the second power divider line 120, respectively. In this embodiment, the first segment 10 and the second segment 20 are located on the first substrate 310 and the second substrate 320, respectively, allowing the first substrate 310 and the second substrate 320 to be fabricated separately as relatively independent printed circuit boards. The first power divider line 110 can be connected and transmit signals through the separate first segment 10 and the second segment 20 via the connector 30. The separately fabricated first substrate 310 and second substrate 320 have a relatively simplified process. Compared to the existing method of fabricating longer substrates to obtain a complete first power divider line structure using suspended traces, the present application's trace 100 can ensure higher consistency. Furthermore, the first substrate 310 and the second substrate 320 are easy to transport separately, and the complete trace 100 structure can be obtained by splicing during installation. That is, the present application's suspended trace 300, using a PCB board trace, also improves consistency and saves costs.
[0112] Understandable. Figure 9 and Figure 10 The illustrations only provide some possible embodiments of the suspended strip 300 of this application. In actual suspended strip products, the first substrate 310 or the second substrate 320 can be further divided based on the actual structure of the strip 100, so that the suspended strip 300 of this application is formed by several interconnected substrates. At this time, the power divider line, which is broken into two segments due to the division of the first substrate 310 or the second substrate 320, is also electrically connected by multiple connectors 30, that is, multiple connectors 30 are connected between any two adjacent substrates to achieve overall conductivity of the strip 100. On the other hand, in addition to the first power divider line 110, the remaining power divider lines, including the second power divider line 120, can also be disposed on interconnected substrates and connected by connectors 30, which is also an implementation of the suspended strip 300 claimed in this application.
[0113] Please see Figure 11The diagram shows the structure on the other side of the PCB trace. For the suspended trace 300 of the PCB trace structure, the first substrate 310 further includes a third outer surface 3102 opposite to the first outer surface 3101, and the second substrate 320 further includes a fourth outer surface 3202 opposite to the second outer surface 3201. It is understood that the third outer surface 3102 and the fourth outer surface 3202 also have the same orientation. On the third outer surface 3102 of the first substrate 310 and the fourth outer surface 3202 of the second substrate 320, a first line 140 for transmitting signals can also be provided. This first line 140 can be another power divider line that is different from the first power divider line 110 and the second power divider line 120, or the first line 140 can also be an auxiliary line of the first power divider line 110, extending synchronously with the first power divider line 110 and connected to the first power divider line 110 through a via (not shown in the figure).
[0114] Please refer to the above. Figure 11a The first line 140 also includes two disconnected parts, wherein the first part 141 is located on the first substrate 310 and the second part 142 is located on the second substrate 320. A connector 30 for signal transmission is also provided between the first part 141 and the second part 142. The connector 30 can also take the form of the aforementioned jumper 31 or patch 32 to realize the signal transmission function on the line 140.
[0115] At this time, in the suspended trace 300 of the PCB trace structure, lines for signal transmission, namely the first power divider line 110 and the first line 140, are respectively provided on opposite sides of the first substrate 310 and the second substrate 320. The first power divider line 110 includes two parts located on the first substrate 310 and the second substrate 320, and the first line 140 also includes two parts located on the first substrate 310 and the second substrate 320. Connectors 30 can be respectively disposed on opposite sides of the first substrate 310 and the second substrate 320 to respectively realize signal transmission between opposite parts of the first power divider line 110 and the first line 140.
[0116] This application will now introduce another wire structure; please refer to [link to relevant documentation]. Figure 12The first segment 10 includes a first extension segment 13, located at the end of the first segment 10 furthest from the signal processing line 130. The first extension segment 13 is made of the same material as the first segment 10 and can be fabricated simultaneously with the first segment 10. The second segment 20 includes a second extension segment 23, located at the end of the second segment 20 closest to the first segment 10. The second extension segment 23 is also made of the same material as the second segment 20 and can be fabricated simultaneously with the second segment 20. Thus, the electrical signal transmitted on the first segment 10 continues to be transmitted towards the first extension segment 13 after reaching the second end 12. The first extension segment 13 can cooperate with the second extension segment 23, transmitting the electrical signal to the second extension segment 23, which then transmits the electrical signal to the second segment 20.
[0117] Please combine Figure 12a As illustrated, in this embodiment, the connector 30 is constructed as a fixing member 33. The fixing member 33 is insulating and is disposed on one side of the first power divider line 110. It is used to fix the first extension segment 13 and the second extension segment 23, and to realize signal transmission between the first extension segment 13 and the second extension segment 23. The fixing member 33 is located on one side of the first power divider line 110, that is, on the same side as the first segment 10 and the second segment 20. At this time, the first extension segment 13 and the second extension segment 23 can extend towards the fixing member 33 simultaneously and be fixed to each other with the fixing member 33, thereby enabling the first extension segment 13 and the second extension segment 23 to realize the function of transmitting electrical signals through cooperation. The insulation of the fixing member 33 ensures that the fixing member 33 will not interfere with the electrical performance of the first extension segment 13 and the second extension segment 23, ensuring reliable transmission of electrical signals.
[0118] Understandably, after the fixing member 33 is fixedly connected to the first power divider 110 from one side of the first power divider 110, the extension direction of the first extension segment 13 is different from the extension direction of the second segment 20. The extension direction of the first extension segment 13 also needs to form an angle with the extension direction of the first segment 10 to ensure that the first extension segment 13 and the fixing member 33 located on one side of the first segment 10 can cooperate. Correspondingly, the extension direction of the second extension segment 23 should preferably be parallel to the extension direction of the first extension segment 13, or the angle between the extension direction of the second extension segment 23 and the extension direction of the first extension segment 13 should be limited to a certain range (e.g., less than or equal to 30 degrees). This can ensure that the first extension segment 13 and the second extension segment 23 form a reliable cooperation relationship and ensure the transmission of electrical signals between the first extension segment 13 and the second extension segment 23. The fixing member 33 is fixed at one side of the first power dividing line 110 along the first direction 001. In one implementation, the first extension segment 13 can extend along the first direction 001, and the second extension segment 23 can also extend along the first direction 001, and respectively cooperate with the fixing member 33 and fix each other.
[0119] In this embodiment, the first extension segment 13 is actually bent relative to the first segment 10, and the second extension segment 23 is also bent relative to the second segment 20. The extension directions of the first extension segment 13 and the second extension segment 23 are parallel or form a small angle range. The fixing member 33 fixes the first extension segment 13 and the second extension segment 23 in the bending direction (first direction 001) to ensure that the first extension segment 13 and the second extension segment 23 can achieve signal transmission through cooperation.
[0120] In one possible implementation, the angle formed by the first direction 001 and the extension direction of the first segment 10 is 90 degrees. That is, the first extension segment 13 extends towards a side perpendicular to the first segment 10. At this time, the second extension segment 23 can also extend along the first direction 001, and the second extension segment 23 also extends towards a side perpendicular to the second segment 20. The bending angle between the first extension segment 13 and the first segment 10 is equal to the bending angle between the second extension segment 23 and the second segment 20. Thus, when the electrical signal is transmitted from the first segment 10 to the first extension segment 13, its path bending angle is 90 degrees; when the second extension segment 23 receives the electrical signal transmitted from the first extension segment 13 and transmits the electrical signal to the second segment 20, the path bending angle of the electrical signal is also 90 degrees. Moreover, the bending angles of the two paths are symmetrical to each other. This structure is beneficial for maintaining the consistency of signal transmission between the first extension segment 13 and the first segment 10, and between the second extension segment 23 and the second segment 20.
[0121] Figure 13This illustration shows a structural diagram of the fastener 33 of this application. The fastener 33 includes a body 333, within which a first through hole 331 and a second through hole 332 are formed, and the first through hole 331 and the second through hole 332 respectively penetrate the body 333. The first through hole 331 is configured to match the shape of the first extension segment 13, and the second through hole 332 is configured to match the shape of the second extension segment 23. Thus, the first extension segment 13 can extend into the body 333 from the first through hole 331 to achieve relative position fixation of the first extension segment 13 relative to the fastener 33 (see [reference]). Figure 14 Correspondingly, the second extension segment 23 can also extend into the body 333 through the second through hole 332 to fix the relative position of the second extension segment 23 relative to the fixing member 33. Since the first through hole 331 and the second through hole 332 are respectively opened in the body 333, the relative positions of the first through hole 331 and the second through hole 332 are fixed. At this time, the relative positions of the first extension segment 13 extending into the first through hole 331 and the second extension segment 23 extending into the second through hole 332 are also fixed to each other, thereby achieving the function of signal transmission.
[0122] In one embodiment, the body 333 further includes a receiving cavity 3331, which is located on one side of the first through hole 331. The receiving cavity 3331 also communicates with both the first through hole 331 and the second through hole 332. (Please refer to...) Figure 14 When the fixing member 33 is fixed relative to the first power dividing line 110, the receiving cavity 3331 is still located on the side of the first through hole 331 away from the first segment 10.
[0123] exist Figure 14 In the illustration, the length of the first extension segment 13 is greater than the extension length of the first through hole 331, causing the first extension segment 13 to extend beyond the first through hole 331 and be at least partially received within the receiving cavity 3331. This portion extending beyond the first through hole 331 is defined as the first connecting end 131, which is located along the first direction 001 on the side of the body 33 opposite to the first power divider line 110. Correspondingly, the length of the second extension segment 23 is also greater than the extension length of the second through hole 332, and it has a second connecting end 231 located on the side of the body 33 opposite to the first power divider line 110. It is understood that the second connecting end 231 is also at least partially received within the receiving cavity 3331.
[0124] The first extension segment 13 and the second extension segment 23 transmit electrical signals through the cooperation between the first connection terminal 131 and the second connection terminal 231. Furthermore, since both the first connection terminal 131 and the second connection terminal 231 are exposed relative to the main body 333, no interference from other media is introduced between them, which facilitates impedance matching between the first extension segment 13 and the second extension segment 23.
[0125] In one embodiment, the first connecting end 131 and the second connecting end 231 are connected by welding. In this case, an electrical signal path is formed between the first connecting end 131 and the second connecting end 231, allowing the electrical signal on the first segment 10 to be directly transmitted to the second extension segment 23 via the first extension segment 13, and further conducted to the second segment 20. In another embodiment, the first connecting end 131 and the second connecting end 231 can also be connected by overlapping, directly realizing the transmission of electrical signals between the first extension segment 13 and the second extension segment 23.
[0126] Because the receiving cavity 3331 simultaneously houses the first connecting end 131 and the second connecting end 231, the solder connecting the first connecting end 131 and the second connecting end 231 is also contained within the receiving cavity 3331, preventing the solder from flowing out of the body 333 and forming a connection with external circuitry. Understandably, when the solder is connected between the first connecting end 131 and the second connecting end 231, the solder can also be used to hold the body 333 in place and prevent the fixing member 33 from sliding towards the first connecting end 131 and detaching from the first power divider line 110.
[0127] Please refer to the above. Figure 14a As illustrated, both the first segment 10 and the second segment 20 are located on the first plane 111. The thickness direction of the first segment 10 extends perpendicular to the first plane 111, and the thickness direction of the second segment 20 also extends perpendicular to the first plane 111. Furthermore, the first direction 001 is also located on the first plane 111. At this time, the first extension segment 13, after being bent relative to the first segment 10, is also located on the first plane 111; correspondingly, the second extension segment 23, after being bent relative to the second segment 20, is also located on the first plane 111. The mating surfaces between the first connecting end 131 and the second connecting end 231 are respectively planes representing the thickness directions of the first connecting end 131 and the second connecting end 231. Figure 14a (Two surfaces with shadows in the middle). This structure results in a smaller relative mating area between the first connecting end 131 and the second connecting end 231, and also a relatively smaller volume of solder required to conduct the connection between the first connecting end 131 and the second connecting end 231 by welding.
[0128] In other embodiments, please refer to Figure 15The strip 100 is shown schematically from another viewing angle. The fastener 33 is also provided with a latch 334. The latch 334 is used to achieve a fixed connection between the fastener 33 and the first power divider line 110. The latch 334 extends towards one side of the body 333 along the extending direction of the first through hole 331, and in embodiments where the body 333 is provided with a receiving cavity 3331, the latch 334 and the receiving cavity 3331 are located on opposite sides of the first through hole 331. A fixing part 3341 is provided on the side of the latch 334 facing away from the body 333. When the fastener 33 is located on one side of the first power divider line 110, the body 333 is attached to one side of the first power divider line 110, and the buckle 334 extends toward the first power divider line 110 in a direction away from the body 333, so that the fixing part 3341 abuts against the surface of the first power divider line 110 away from the body 333, thereby preventing the fastener 33 from sliding along the extension direction of the first through hole 331 and slipping off the first extension section 13.
[0129] The latch 334 can have a certain degree of elasticity, allowing the fixing part 3341 to slide relative to the first power distribution line 110. During this process, the latch 3344 can elastically deform to bypass the outer contour of the first power distribution line 110, and return to its original shape after the fixing part 3341 is located on the side of the first power distribution line 110 away from the body 333, thereby providing resistance to the first power distribution line 110. It is understood that the fixing part 3341 can provide resistance to any part of the first segment 10 and / or the second segment 20, thereby fixing the position between the fixing member 33 and the first power distribution line 110. In some embodiments, multiple latches 334 can be provided, each fixedly connected to the body 333, and each latch 334 correspondingly forming multiple fixing parts 3341, thereby providing resistance to the first power distribution line 110 from different positions to ensure effective fixation between the fixing member 33 and the first power distribution line. Understandably, in other embodiments, the fastener 33 may also be fixed to the first power dividing line 110 in any form such as binding or adhesive to define the relative position between the first extension segment 13 and the second extension segment 23.
[0130] The suspension cable 300 in this application does not limit the specific shape of the fastener 33; the fastener 33 can be as follows: Figure 13 The structure shown is cylindrical, meaning the main body 333 has a cylindrical structure. In this case, the receiving cavity 3331 can also be constructed as a cylindrical cavity, with the wall thickness remaining consistent at all edges of the receiving cavity 3331. The fixing member 33 can also be as follows... Figure 15 The structure shown is a cuboid, that is, the main body 333 is constructed as a cuboid. At this time, the receiving cavity 3331 can also be constructed as a rectangular cavity, and the wall thickness of the receiving cavity 3331 is consistent at all positions of the edge.
[0131] The first extension segment 13 and the second extension segment 23 can also achieve signal transmission through coupling. Please refer to [link / reference]. Figure 16and Figure 17 The illustrated embodiment, wherein Figure 16 This is a top view of fastener 33. Figure 17 This is a cross-sectional schematic diagram of the fastener 33. A capacitor is formed by a gap between the first connecting end 131 and the second connecting end 231, and through their opposing outer surfaces (…). Figure 16 and Figure 17 The surface indicated by the dashed midpoint (where electrical signals are coupled and transmitted) is used for this purpose. Figure 16 and Figure 17 In this embodiment, the first direction 001 is preferably set perpendicular to the first plane 111. At this time, the two outer surfaces of the first connecting end 131 and the second connecting end 231 are the two outer surfaces in their respective linewidth directions, and the mating area between the first connecting end 131 and the second connecting end 231 is larger, which can achieve a better coupling effect.
[0132] In one embodiment, by setting the distance between the first through hole 331 and the second through hole 332, the distance between the first connecting end 131 and the second connecting end 231 can be controlled, thereby ensuring the capacitance value between the first connecting end 131 and the second connecting end 231 and reducing the signal loss when the first connecting end 131 and the second connecting end 231 are coupled. For example, the distance between the first connecting end 131 and the second connecting end 231 can be controlled to be less than or equal to 0.5 mm and greater than or equal to 0.1 mm.
[0133] In one embodiment, the linewidth d1 of the first extension segment 13 is less than or equal to the linewidth D1 of the first segment 10, and simultaneously less than or equal to the linewidth D2 of the second segment 20; the linewidth d2 of the second extension segment 23 is also less than or equal to the linewidth D1 of the first segment 10, and simultaneously less than or equal to the linewidth D2 of the second segment 20. Therefore, the linewidths d1 and d2 of the first connection terminal 131 and the second connection terminal 231 are also correspondingly less than or equal to the linewidth D1 of the first segment 10 and the linewidth D2 of the second segment 20. This arrangement ensures that when the first connection terminal 131 transmits signals with the second connection terminal 231, its impedance can be matched with the impedances of the first segment 10 and the second segment 20, respectively.
[0134] In some embodiments, the line width d1 of the first extension segment 13 can be set to be equal to the line width d2 of the second extension segment 23, and the line widths D1 and D2 between the first segment 10 and the second segment 20 can also be equal, thereby improving the overall line width consistency of the first power distribution line 110.
