Description

Technical Field

[0001] The present invention relates to the technical field of cables, and in particular to a cable device with self-contained mode conversion and a signal conversion method thereof. Background Art

[0002] In electrical engineering, differential output signals are a common signal transmission method, suitable for application scenarios that require improved signal integrity, anti-interference capabilities, and long-distance transmission. For example, in analog signal applications, oscilloscope probes, precision instruments, etc. use differential input and output to improve signal measurement accuracy; RF ICs in RF transmission and receiving modules usually use differential signals to transmit RF signals to improve anti-interference capabilities and signal integrity; in the battery management system of electric vehicles, differential signals are used to detect battery pack voltage and temperature; when designing PCBs, keep the length of differential input signal lines matched to avoid phase deviation caused by asymmetry.

[0003] In practical applications, the transmission of differential signals requires the use of two cables of the same specifications for energy transfer; the corresponding electrical equipment is generally designed with two ports for connecting these two cables of the same specifications to receive differential signals. In high-frequency environments, differential signals will be significantly affected by parasitic effects, resulting in signal distortion. In order to reduce interference and distortion, it is also necessary to design a differential input circuit. The existing differential input circuit is usually composed of a high-precision differential amplifier, a matching network, and a filter circuit. However, for application scenarios with broadband signal requirements (such as radio frequency communications), the differential input circuit must support a wider frequency range, which makes the design of matching circuits and filters extremely complicated, and the final performance may not be ideal. It is difficult to strictly guarantee the amplitude and phase symmetry of the two-way feed signals, thereby reducing the working accuracy of the electrical equipment. Summary of the invention

[0004] The present invention provides a cable device with self-contained mode conversion and a signal conversion method thereof, which are used to solve the technical problem that in the existing high-frequency broadband signal transmission scenario, the circuit design of the differential design circuit is complex, and it is difficult to maintain the amplitude and phase symmetry of the two-way feed signal, thereby reducing the working accuracy of the electrical equipment. At the same time, when interface conversion is required between some electrical devices, the present invention can directly convert the differential signal into a single-ended signal.

[0011] The gradient structure of the lower metal cladding extends from wide to narrow to the parallel transition structure of the lower metal cladding, and the wide portion of the gradient structure of the lower metal cladding is connected to the integrated cable structure.

[0012] Furthermore, the cross section of the gradual change structure is formed by a curved surface gradual change extension structure or a planar stepped gradual change extension structure.

[0013] Furthermore, the extended ends of the tapered structure of the upper metal cladding and the tapered structure of the lower metal cladding are of the same size.

[0014] Furthermore, the upper metal edging and the lower metal edging are respectively arranged on the upper side and the lower side of the outer wall of the dielectric material structure.

[0015] Furthermore, the parallel transition structures of the upper metal cladding and the lower metal cladding are both attached to the outer wall of the dielectric material structure and extend along the axial direction thereof, for connecting electrical equipment.

[0016] Furthermore, the parallel transition structure of the upper metal edging and the parallel transition structure of the lower metal edging are manufactured with the same size structure.

[0017] Furthermore, the dielectric material structure specifically adopts Taconic RF-35 material with a dielectric constant of 3.5.

[0018] Furthermore, the thickness range of the upper metal edging and the lower metal edging specifically includes 0.6mm~1mm.

[0019] The second aspect of the present invention further provides a signal conversion method of a cable device with self-contained mode conversion, comprising:

[0020] When the coaxial cable mode is converted into the differential mode, the first current signal outputted by the cable core is transmitted to the upper metal cladding to form an electric field in the dielectric material structure; the electric field is coupled with the magnetic field formed around the cable core to generate a second current signal on the integrated cable structure and transmit the second current signal to the lower metal cladding; based on the gradient structure of the upper metal cladding and the lower metal cladding, the first current signal and the second current signal are converted from the unbalanced mode to the balanced mode to generate a set of differential signals with the same amplitude and opposite phases; the differential signal is transmitted to the electrical device through the parallel transition structure of the upper metal cladding and the lower metal cladding;

DETAILED DESCRIPTION

[0034] The embodiment of the present invention provides a cable device with built-in mode conversion and a signal conversion method thereof, which are used to solve the technical problem that in the existing high-frequency broadband signal transmission scenario, the circuit design of the differential design circuit is complex and it is difficult to maintain the amplitude and phase symmetry of the two-way feeding signal, thereby reducing the working accuracy of the electrical equipment.

[0035] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0037] Unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] See also Figure 1-Figure 5, an embodiment of a cable device with self-contained mode conversion provided by the present application includes: an integrated cable structure 1, a metal component and a dielectric material structure 5;

[0039] The integrated cable structure 1 is provided with an accommodating channel 11, through which the dielectric material structure 5 and the cable inner core 2 pass; the cable inner core 2 is partially embedded in the dielectric material structure 5;

[0040] The metal component covers the outer wall circumference of the dielectric material structure 5; the metal component includes an upper metal edging 3 and a lower metal edging 4; the upper metal edging 3 is provided with a connection port 31, and the connection port 31 is used for the cable core 2 to extend; the upper metal edging 3 and the lower metal edging 4 are both connected to the integrated cable structure 1, and the upper metal edging 3 and the lower metal edging 4 are both composed of a gradual structure and a parallel transition structure.

[0041] It is understandable that the integrated cable structure 1 can be set with an inner diameter and a length according to the specifications of the dielectric material structure 5. When actually feeding, the cable core 2 extends through the reserved connection port 31 in the upper metal cladding 3 to form a stable feeding. Figure 1 The cable core 2 can pass through the connection port 31 of the upper metal cladding 3 in a bending manner, thereby establishing an electrical connection between the cable core 2 and the upper metal cladding 3 .

[0042] It should be noted that the cable device provided by the present invention has the function of mutual conversion between coaxial cable mode and differential output mode to adapt to different application scenarios; among them, converting the coaxial cable mode to differential output mode is suitable for application scenarios that need to improve signal integrity, anti-interference ability and long-distance transmission; and converting the differential output mode to coaxial cable mode is suitable for industrial automation systems, embedded systems and communication protocol converters, communication interface conversion, and long-distance signal transmission application scenarios. For example, communication interface conversion: when interface conversion is required between some devices, differential signals (such as RS-485, LVDS, etc.) often need to be converted into single-ended electrical signals; long-distance signal transmission: differential signals show good anti-interference ability in long-distance transmission, but in some systems, the receiving end may not have the ability to process differential signals, and then it is necessary to convert differential signals into single-ended electrical signals.

[0043] Among them, the conversion process of converting the coaxial cable mode into the differential mode is as follows: the current signal output by the cable core 2 is transmitted to the upper metal edging 3 through the feeding point formed by the connecting port 31. Since the cable core 2 is a conductor with current, a magnetic field will be formed on its periphery, and an electric field will be formed in the dielectric material structure 5 at the same time; the electric field and magnetic field formed by coupling generate a current signal on the integrated cable structure 1 that is opposite to the current phase of the cable core 2; the current signal generated by the integrated cable structure 1 is transmitted to the lower metal edging 4; in order to achieve the same amplitude of the two current signals, the present invention designs the metal component into a special structure with a gradual slit, that is, the upper metal edging 3 and the lower metal edging 4 are both composed of a gradual structure and a parallel transition structure, thereby converting the current signal from an unbalanced mode to a balanced mode, achieving the consistency of the amplitude of the output current of the two metal edgings, thereby generating a stable differential signal, and then converting the coaxial cable mode into a differential output mode.

[0044] Correspondingly, the conversion process from the differential mode to the coaxial cable mode is as follows: the differential signal is transmitted by the parallel transition structure of the upper metal cladding 3 and the lower metal cladding 4, and the two current signals with opposite phases and consistent amplitudes are respectively transmitted to the gradient structure 32 of the upper metal cladding and the gradient structure 41 of the lower metal cladding, wherein the current signal transmitted by the upper metal cladding 3 flows to the cable core 2 through the connector, and during the transmission process, the electrical signal of the cable core 2 will generate an electric field surrounding the conductor, and this electric field will form an electromagnetic wave as the signal propagates, and the electromagnetic wave will be transmitted to the integrated cable structure 1 through the wrapped dielectric material structure 5, thereby realizing the conversion of the differential mode into the coaxial mode and finally outputting a single-ended electrical signal; and the current signal transmitted by the lower metal cladding 4 will also flow to the integrated cable structure 1, but will have almost no effect, i.e. will not affect the conversion of the coaxial mode.

[0045] In a specific embodiment, the gradient structure 32 of the upper metal cladding extends from narrow to wide to the parallel transition structure 33 of the upper metal cladding, a connection port 31 is provided in the narrow portion of the gradient structure 32 of the upper metal cladding, and the narrow portion of the gradient structure 32 of the upper metal cladding is connected to the integrated cable structure 1; the gradient structure 41 of the lower metal cladding extends from wide to narrow to the parallel transition structure 42 of the lower metal cladding, and the wide portion of the gradient structure 41 of the lower metal cladding is connected to the integrated cable structure 1; the extended ends of the gradient structure 32 of the upper metal cladding and the gradient structure 41 of the lower metal cladding are the same size, thereby converting the current signal from an unbalanced mode to a balanced differential output mode, thereby forming a set of differential energies with consistent amplitudes and a phase difference of 180°.

[0046] It can be understood that the metal edging of this embodiment adopts a unique gradient slit method to form an upper metal edging 3 and a lower metal edging 4, and the two metal edgings adopt different gradient structures, wherein the gradient structure 32 of the upper metal edging extends from narrow to wide, and the gradient structure 41 of the lower metal edging extends from wide to narrow, and finally the sizes of the two at the end of the gradient structure are the same, thereby balancing the differential signal.

[0047] When the coaxial cable mode is converted into the differential mode, the current signal output by the cable core 2 is transmitted to the narrow part of the gradient structure 32 of the upper metal cladding through the connecting port 31, and the gradient structure 32 extending from narrow to wide based on the upper metal cladding 3 converts the current signal into an unbalanced mode; correspondingly, the current signal based on the coupling of the electric field and the magnetic field is transmitted by the integrated cable structure 1 to the wide part of the lower metal cladding 4 connected thereto, and the gradient structure 41 extending from wide to narrow based on the lower metal cladding 4 converts the current signal into an unbalanced mode; finally, since the extension ends of the gradient structure 32 of the upper metal cladding and the gradient structure 41 of the lower metal cladding are the same in size, the current amplitudes output by the gradient structures of the two metal claddings are successfully consistent, and then a set of differential energy with consistent amplitudes and a phase difference of 180° is output, thereby ensuring the working accuracy of the electrical equipment.

[0048] In a specific embodiment, see Figure 1 and Figure 4 The cross section of the gradual change structure is formed by a curved gradual change extension structure or a planar stepped gradual change extension structure. In the stepped gradual change extension structure, both sides of the gradual change structure are extended by a plurality of stepped structures of equal size.

[0049] In a specific embodiment, the upper metal cladding 3 and the lower metal cladding 4 are respectively arranged on the upper side and the lower side of the outer wall of the dielectric material structure 5 .

[0050] In a specific embodiment, the parallel transition structures 42 of the upper metal edging 3 and the lower metal edging 4 are both attached to the outer wall of the dielectric material structure 5 and extend along its axial direction, and are used to connect electrical equipment, and transmit differential energy with consistent amplitude and 180° phase difference to the electrical equipment when the coaxial cable mode is converted into the differential mode. Among them, the length of the parallel transition structure does not affect the conversion performance of the gradient structure. In practical applications, the design length of the parallel transition structure can be adjusted according to the required length. At the same time, the present invention is directly connected to the electrical equipment at the single cable level, which reduces the error and loss of the signal transmitted from the power supply to the cable and then to the electrical equipment, and improves the working efficiency of the electrical equipment.

[0051] In a specific embodiment, in order to ensure the stability of the transmitted differential signal, the parallel transition structure 33 of the upper metal cladding and the parallel transition structure 42 of the lower metal cladding are made with the same size structure.

[0052] In a specific embodiment, the dielectric material structure 5 is preferably Taconic RF-35 material with a dielectric constant of 3.5.

[0053] In a specific embodiment, the thickness of the upper metal edging 3 and the lower metal edging 4 specifically ranges from 0.6 mm to 1 mm. At the same time, the width and narrowness of the gradient structure of the two metal edgings will not exceed half of the edging perimeter formed by the complete metal component.

[0054] In a specific embodiment, the metal edging and the integrated cable structure 1 are both made of metal materials, such as conventional metal materials such as copper. During manufacturing, an integrated manufacturing process can be used, that is, the parallel transition structure, the gradient structure and the integrated cable structure 1 are manufactured in an integrated manner, without the need for re-welding, thus saving the manufacturing process time, and only processing and cutting are required according to actual needs.

[0055] See also Figure 6 and Figure 7 This embodiment also provides an example diagram of an electrical simulation result of a cable device with self-contained mode conversion connected to an electrical device in an electromagnetic simulation design software. Among them, the reflection coefficient |S 11 | and |S 22 | indicates the transmission capacity from one port to another in the cable device, specifically the ratio of reflected power to output power. The smaller the value, the better the transmission performance of the cable device; |S 11 | represents the transmission capability from the coaxial mode port to the differential mode port, and |S 22 | indicates the transmission capability from the differential mode port to the coaxial mode port; |S 12 | represents the loss of cable transmission. The closer the loss is to 0, the lower the loss is. Figure 6 It can be seen that the reflection coefficient of the cable device in the ultra-wideband (1GHz-30GHz frequency band) |S 11 | and |S 22 | are less than -20dB, and Figure 6 Medium reflection coefficient |S 12 |The loss variation within the frequency band also shows that the cable installation has almost no loss during transmission. Figure 7 It can be seen that the phase difference of the output signals at the output ports of the parallel transition structure of the cable device within the matching bandwidth is around 180°, meeting the requirement of differential output.

[0056] The cable device with self-contained mode conversion provided by the present invention has the following advantages:

[0057] 1. The cable device provided by the present invention has a function of mutual conversion between a coaxial cable mode and a differential output mode; wherein, when the coaxial cable mode is converted into the differential mode, two current signals with opposite phases are generated based on the structural relationship among the dielectric material structure, the integrated cable structure and the metal component, and the two current signals are converted from an unbalanced mode to a balanced mode based on the gradual structure of the metal edging, so that the amplitudes of the two current signals are consistent, thereby ensuring the amplitude and phase symmetry of the two feed signals and improving the working accuracy of the electrical equipment; when the differential mode is converted into the coaxial cable mode, the differential signal can be directly converted into a single-ended signal, so as to facilitate the interface conversion between the electrical equipment.

[0058] 2. The cable device has a simple structure and does not require the use of electrical components to implement circuit design, so it will not be affected by parasitic effects and can also reduce the cost of manufacturing related equipment. In addition, the present invention uses simple components such as integrated cable structures, metal components and dielectric material structures to design the cable device to complete the mutual conversion of coaxial signals and differential signals and single-ended transmission functions. There is no need to design a complex differential input circuit and is not subject to the application restrictions of high-frequency and ultra-wide signal bands, which solves the problem of small bandwidth range of existing electrical equipment.

[0059] 3. The present invention can reduce the error and loss of differential signals transmitted from power supply to cable and then to electrical equipment by realizing signal connection with electrical equipment at a single cable level, thereby improving the signal transmission efficiency of the entire electrical system.

[0060] See also Figure 8 The present invention also provides a signal conversion method of a cable device with self-contained mode conversion, comprising:

[0061] Step 101, when the coaxial cable mode is converted into the differential mode, the first current signal output by the cable inner core is transmitted to the upper metal cladding to form an electric field in the dielectric material structure; the electric field is coupled with the magnetic field formed on the circumference of the cable inner core to generate a second current signal on the integrated cable structure and transmit the second current signal to the lower metal cladding; based on the gradient structure of the upper metal cladding and the lower metal cladding, the first current signal and the second current signal are converted from the unbalanced mode to the balanced mode to generate a set of differential signals with the same amplitude and opposite phases; the differential signal is transmitted to the electrical device through the parallel transition structure of the upper metal cladding and the lower metal cladding;

[0062] It can be understood that the cable core is extended from the connection port of the upper metal cladding, thereby establishing an electrical connection between the cable core and the upper metal cladding, and then the first current signal output by the cable core is transmitted to the upper metal cladding; wherein the cable core is a conductor that is energized, and it is in contact with the dielectric material structure, so that the dielectric material structure can form an electric field; at the same time, a magnetic field is formed on the circumference of the cable core, and the formed electric field is coupled with the magnetic field, so that a current signal with a phase opposite to that of the cable core is generated on the integrated cable structure;

[0063] In particular, in order to achieve consistent amplitudes of the two current signals, a special gradient structure is designed in this step to convert the first current signal and the second current signal from an unbalanced mode to a balanced mode, wherein the gradient structure of the upper metal edging extends from narrow to wide to the parallel transition structure of the upper metal edging; and the gradient structure of the lower metal edging extends from wide to narrow to the parallel transition structure of the lower metal edging.

[0064] Step 102, when the differential mode is converted into the coaxial cable mode, one signal in the differential signal is transmitted to the gradient structure of the upper metal cladding by the parallel transition structure, and one signal flows to the inner core of the cable through the connection port of the upper metal cladding; during the transmission process, the electrical signal in the inner core of the cable will generate an electric field surrounding the conductor, and the electric field will form an electromagnetic wave as the signal propagates, and the electromagnetic wave will be transmitted to the integrated cable structure through the wrapped dielectric material structure to generate and output a single-ended electrical signal.

[0065] It should be noted that the other signal in the differential signal will be transmitted to the gradient structure of the lower metal cladding, and then the other signal will flow to the integrated cable structure through the lower metal cladding. This signal will not affect the conversion of the coaxial mode.

[0066] As described above, the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features thereof may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
