Description
Technical Field
The present application relates to the field of communications technologies, and in particular, to a transmission cable and an electronic device.
Background
In the working condition of the antenna, the energy is transmitted through the incident current and the reflected current inside the outer core of the feeder cable of the antenna. In antenna design, it is generally desirable that the feeder cable only plays a role in transmission and does not radiate, but the feeder cable itself lacks structural symmetry, so that the feeder is unbalanced and energy is exposed, in which case common mode current is generated outside the outer core of the feeder cable, which should not radiate, so that radiation is generated, and the performance of the antenna is greatly affected. The magnitude of the common mode current is not controllable, the direction is unpredictable and the simulation is difficult. Therefore, how to suppress the generation of the common mode current or eliminate the common mode current as much as possible, thereby improving the antenna performance is important for the design of the antenna.
In the prior art, the common mode current on the outer surface of the feeder cable is lost by the choke ring by sleeving the choke ring on the outer surface of the feeder cable, so that the radiation of the feeder cable is reduced, and the performance of the antenna is optimized.
However, in practice, the applicant has found that by sleeving the choke ring on the outside of the feeder cable, the following drawbacks exist:
firstly, the choke ring and the feeder cable are designed and produced independently, and the integral design of the feeder cable is not utilized;
Secondly, in the using process of the feeder cable, one or more choke rings are required to be opened, and after the feeder cable is placed in the choke rings, the choke rings are closed again, so that the process is complex and the overall design is not facilitated;
Thirdly, a plurality of choke rings are required to be arranged according to the length of the feeder cable so as to play a role in restraining common mode current, so that a large number of choke rings are required to be arranged on the feeder cable, and the cost is increased;
Fourth, since the choke coil is small, the feeder cable length that can be covered is relatively short, and therefore the loss path is short, the effect of suppressing the common mode current is generally not ideal.

In addition, the outer magnetic ring covers the outside of the transmission line, and the inner magnetic ring is positioned in the transmission line, so that the loss path can be prolonged, and the suppression effect of the common mode current can be effectively improved. In addition, a plurality of choke rings are not required to be arranged outside the transmission cable, so that the cost can be saved.

Detailed Description
Embodiments of the present application are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present application and should not be construed as limiting the application.
Currently, a feeder cable includes an inner core (signal line) and an outer core (shield layer), and in the case of an antenna operation, as shown in fig. 1, energy is transmitted through an incident current (solid line 1 in fig. 1) and a reflected current (solid line 2 in fig. 1) inside the outer core of the feeder cable of the antenna. However, due to the lack of structural symmetry of the feeder cable itself, common mode currents (dashed line 3 in fig. 1) are generated outside the outer core, greatly affecting the performance of the antenna.
In the prior art, as shown in fig. 2, by sleeving one or more choke rings on the outer surface of the feeder cable, the common mode current on the outer surface of the feeder cable is lost by the choke rings, so that the radiation of the feeder cable is reduced, and the performance of the antenna is optimized.
However, in the use of the feeder cable, as shown in fig. 3, it is necessary to open one or more choke rings, and close the choke rings after the feeder cable is put into the choke rings, which is complicated in process and is disadvantageous in the overall design. In addition, a plurality of choke rings are required to be arranged according to the length of the feeder cable to suppress the common mode current, so that a large number of choke rings are required to be arranged on the feeder cable, and the cost is increased. Further, since the choke ring is small, the feeder cable length that can be covered is relatively short, and therefore the loss path is short, the effect of suppressing the common mode current is generally not ideal.
Therefore, the application mainly aims at the technical problems of complex procedures, adverse overall design, high cost and unsatisfactory effect of suppressing common mode current in the prior art.
According to the transmission cable provided by the embodiment of the application, the transmission line is arranged in the body, and the outer magnetic ring and/or the inner magnetic core are arranged in the body, wherein the transmission line is arranged in the outer magnetic ring, and the inner magnetic core is arranged in the transmission line. Thus, by providing the outer magnetic ring outside the transmission line and/or the inner magnetic core inside the transmission line, the function of transmitting energy and the function of suppressing the common mode current can be simultaneously realized. And the outer magnetic ring and/or the inner magnetic core are/is arranged inside the transmission cable, so that the condition that the choke ring is frequently opened in the process of using the cable in the prior art can be avoided, the process is simplified, and the overall design of the transmission cable is facilitated. In addition, the outer magnetic ring covers the outside of the transmission line, and the inner magnetic ring is positioned in the transmission line, so that the loss path can be prolonged, and the suppression effect of the common mode current can be effectively improved. In addition, a plurality of choke rings are not required to be arranged outside the transmission cable, so that the cost can be saved.
The transmission cable and the electronic device according to the embodiment of the present application are described below with reference to the drawings.
Fig. 4 is a schematic structural diagram of a transmission cable according to an embodiment of the application.
As shown in fig. 4, the transmission cable 100 includes: a body (not shown in fig. 4), a transmission line 10, an outer magnetic ring 20, and an inner magnetic core 30.
Wherein the transmission line 10 is disposed within the body, a first end of the transmission line 10 is connected to the antenna, and a second end of the transmission line 10 is connected to the radio frequency component.
The outer magnetic ring 20 and the inner magnetic core 30 are disposed within the body, wherein the transmission line 10 is disposed inside the outer magnetic ring 20, and the inner magnetic core 30 is disposed inside the transmission line 10.
It should be noted that, the transmission cable 100 of the embodiment of the present application may include a body, a transmission line 10 and an outer magnetic ring 20, or the transmission cable 100 may include a body, a transmission line 10 and an inner magnetic core 30, or the transmission cable 100 may include a body, a transmission line 10, an outer magnetic ring 20 and an inner magnetic core 30, and fig. 4 only illustrates that the transmission cable 100 includes a body, a transmission line 10, an outer magnetic ring 20 and an inner magnetic core 30.
In the embodiment of the present application, the transmission line 10 includes an inner core (signal line) and an outer core (shielding layer), and the transmission function of energy can be achieved by providing the transmission line 10 in the transmission cable 100. By providing the outer magnetic ring 20 in the transmission cable 100, a function of suppressing the common mode current outside the outer core (shielding layer) can be realized, and by providing the inner magnetic core 30 in the transmission cable 100, a function of suppressing the common mode current can be also realized.
Specifically, by providing the transmission line 10, the outer magnetic ring 20, and/or the inner magnetic core 30, on the one hand, high impedance can be formed, which functions as a barrier to the downward flow of the common mode current, and on the other hand, the common mode current that has already flowed downward can be lost by the transmission line 10 having a longer length provided in the outer magnetic ring 20. Therefore, the transmission cable 100 in the present application can suppress more common mode current flowing from the antenna onto the transmission line 10 than a normal feeder cable.
The transmission line 10 may be disposed in the transmission cable 100 in a spiral or polygonal manner, or the transmission line 10 may be disposed in the transmission cable 100 in any manner that the transmission line 10 may be disposed in the outer magnetic ring 20, which is not limited in the present application. Thus, the longer transmission line 10 (for example, 1 meter) is arranged in the shorter outer magnetic ring 20 (for example, 10 cm), that is, the longer transmission line 10 is arranged in the very short outer magnetic ring 20, so that the current loss path can be increased, the common mode current is consumed as much as possible, and the effect of effectively suppressing the common mode current is achieved. And, the overall length of the transmission cable 100 can be reduced, ensuring the transmission performance of the transmission cable.
For example, the transmission line 10 may be disposed in the transmission cable 100 in a spiral manner, or the transmission line 10 may be disposed in the transmission cable 100 in a zigzag manner, or the transmission line 10 may be disposed in the transmission cable 100 in a spiral and zigzag manner, and so on. Fig. 4 illustrates only the transmission line 10 being disposed in the transmission cable 100 in a spiral manner.
As an example, when the transmission line 10 is disposed in the transmission cable 100 in a spiral manner, a side sectional view and a top sectional view of the transmission cable 100 may be as shown in fig. 5.
As another example, when the transmission line 10 is disposed in the transmission cable 100 by a fold line, a front sectional view of the transmission line 10 and a top sectional view of the transmission cable 100 may be as shown in fig. 6.
In the present application, since the transmission line 10 itself includes an inner core (signal line) and an outer core (shielding layer), the inside of the transmission line 10 mentioned above refers to the inside of the structure formed by the entire transmission line 10, and the outside of the transmission line 10 refers to the outside of the structure formed by the entire transmission line 10. As shown in fig. 5, the inner core 30 provided inside the transmission line 10 means the inner core 30 provided inside the spiral wound around the transmission line 10, and the outer magnetic ring 20 provided outside the transmission line 10 means the outer magnetic ring 20 provided outside the spiral wound around the transmission line 10.
In the embodiment of the present application, the outer magnetic ring 20 in the transmission cable 100 is made of a magnetic material, including but not limited to one or more of ferrite, a wave-absorbing material, and other magnetic loss materials. Likewise, magnetic materials are also used for the inner core 300 in the transmission cable 100, including but not limited to one or more of ferrite, wave-absorbing materials, and other magnetically lossy materials.
As an example, in which the transmission line 10 is disposed in the transmission cable 100 in a spiral manner, when the transmission cable 100 includes the body, the transmission line 10, and the outer magnetic ring 20, an oblique cross-sectional view, a side cross-sectional view, and a top cross-sectional view of the transmission cable 100 may be as shown in fig. 7. The transmission line 10 is disposed inside the outer magnetic ring 20, and two ends of the transmission line 10 respectively penetrate from two ends of the outer magnetic ring 20, wherein one end of the transmission line 10 is denoted as a first end in the present application and is connected to an antenna, for example, a radiating element of the antenna, and the other end of the transmission line 10 is denoted as a second end in the present application and is connected to other radio frequency components.
As another example, illustrated in a transmission line 10 disposed in a spiral manner in a transmission cable 100, when the transmission cable 100 includes a body, the transmission line 10, and an inner core 30, an oblique cross-sectional view, a side cross-sectional view, and a top cross-sectional view of the transmission cable 100 may be as shown in fig. 8. Wherein the transmission line 10 is arranged outside the outer magnetic ring 20, a first end of the transmission line 10 is connected to the antenna, for example to a radiating element of the antenna, and a second end of the transmission line 10 is connected to other radio frequency components.
As yet another example, illustrated in a transmission line 10 disposed in a spiral manner within a transmission cable 100, when the transmission cable 100 includes a body, the transmission line 10, an outer magnetic ring 20, and an inner magnetic core 30, a side sectional view and a top sectional view of the transmission cable 100 may be as shown in fig. 9. Wherein the transmission line 10 is arranged inside the outer magnetic ring 20, the inner magnetic core 30 is arranged inside the transmission line 10, a first end of the transmission line 10 is connected to an antenna, for example to a radiating element of the antenna, and a second end of the transmission line 10 is connected to other radio frequency components. Thus, by providing the inner magnetic core 30 and the outer magnetic ring 20 inside and outside the transmission line 10, respectively, it is possible to perform a function of better suppressing the common mode current.
The transmission cable 100 according to the embodiment of the present application is formed by disposing the transmission line 10 inside the body and disposing the outer magnetic ring 20 and/or the inner magnetic core 30 inside the body, wherein the transmission line 10 is disposed inside the outer magnetic ring 20 and the inner magnetic core 30 is disposed inside the transmission line 10. Thus, by providing the outer magnetic ring 20 outside the transmission line 10 and/or providing the inner magnetic core 30 inside the transmission line 10, both the function of transmitting energy and the function of suppressing the common mode current can be achieved. In addition, the outer magnetic ring 20 and/or the inner magnetic core 30 are arranged inside the transmission cable 100, so that the condition that the choke ring is frequently opened in the process of using the cable in the prior art can be avoided, the process is simplified, and the overall design of the transmission cable 100 is facilitated. In addition, the outer magnetic ring 20 covers the outside of the transmission line 10, and the inner magnetic ring 30 is positioned inside the transmission line 10, so that the loss path can be prolonged, and the suppression effect of the common mode current can be effectively improved. In addition, there is no need to provide a plurality of choke rings outside the transmission cable 100, and costs can be saved.
In the embodiment of the present application, since the transmission line 10 may be disposed in the transmission cable 100 in a spiral and/or zigzag manner, the linear length of the transmission line 10 is greater than the linear length of the outer magnetic ring or greater than the linear length of the inner magnetic core 30 after the transmission line is straightened. For example, referring to fig. 7, the transmission line 10 has a linear length that is greater than the linear length of the outer magnetic ring 20 after being straightened, and for another example, referring to fig. 8, the transmission line 10 has a linear length that is greater than the linear length of the inner magnetic core 30 after being straightened. Therefore, the longer transmission line 10 can be arranged inside the shorter outer magnetic ring 20, namely, the longer transmission line 10 is arranged inside the very short outer magnetic ring 20, so that the current loss path can be increased, the common mode current is consumed as much as possible, and the effect of effectively suppressing the common mode current is achieved. Compared with the prior art that a choke ring is sleeved on a long feeder cable, the feeder cable has larger volume and cannot be applied to actual production, the overall length of the transmission cable 100 can be greatly reduced, and the transmission performance of the transmission cable is ensured.
It should be noted that, the transmission line 10 and the outer magnetic ring 20 may be disposed in a close fit, or a gap may be disposed between the transmission line 10 and the outer magnetic ring 20, which is denoted as a first gap in the present application. That is, in the present application, there is a need for non-interference and non-overlapping between the outer magnetic ring 20 and the transmission line 10 to ensure the transmission performance of the transmission cable 100, while ensuring the suppression effect of the common mode current.
Similarly, the transmission line 10 and the inner magnetic ring 30 may be closely matched, or a gap may be formed between the transmission line 10 and the inner magnetic ring 30, which is denoted as a second gap in the present application. That is, in the present application, there is a need for non-interference and non-overlapping between the inner magnetic ring 30 and the transmission line 10 to ensure the transmission performance of the transmission cable 100, while ensuring the suppression effect of the common mode current.
As an example, in the case where the transmission line 10 is disposed in the transmission cable 100 in a spiral manner, when the transmission cable 100 includes a body, the transmission line 10, the outer magnet ring 20, and the inner magnet core 30, as shown in fig. 10, there is a first gap between the outer magnet ring 20 and the transmission line 10, and a second gap between the inner magnet core 30 and the transmission line 10.
As a possible implementation, the outer magnetic ring 10 may be provided with one layer in the transmission cable 100, or may be provided with multiple layers, so as to ensure the suppression effect of the common mode current. Similarly, the inner magnetic ring 30 may be provided with one layer in the transmission cable 100, or may be provided with multiple layers to ensure the suppression effect of the common mode current. Fig. 4 illustrates only one layer of the outer magnetic loop 10 and the inner magnetic loop 30 disposed in the transmission cable 100.
As a possible implementation, the transmission line 10 in the transmission cable 100 may be a coaxial line, or may be a microwave radio frequency transmission line, such as a microstrip line, a strip line, a waveguide, a coplanar waveguide, or the like.
As another possible implementation, the transmission line 10 in the transmission cable 100 may be one or may be plural (such as coaxial lines).
As an example, with the transmission line 10 as two coaxial lines, when the transmission cable 100 includes two transmission lines 10, a perspective sectional view, a side sectional view, and a top sectional view of the transmission cable 100 may be as shown in fig. 11.
