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
Under the working condition of the antenna, energy is transmitted through incident current and reflected current inside the outer core of the feed cable of the antenna. In the design of the antenna, it is generally desirable that the feeder cable only performs a transmission function and does not radiate, but because the feeder cable itself lacks structural symmetry, the feeder is unbalanced and energy is exposed, in this case, a common-mode current is generated outside the outer core of the feeder cable, which should not generate radiation, so as to generate radiation, and the performance of the antenna is greatly affected. The magnitude of the common mode current is not controllable, the direction is unpredictable, and simulation is difficult. Therefore, it is important for the design of the antenna to suppress the generation of the common mode current or eliminate the common mode current as much as possible, thereby improving the performance of the antenna.
In the prior art, a choke ring is sleeved on the outer surface of a feed cable, so that the common-mode current on the outer skin of the feed cable is lost by the choke ring, the radiation of the feed cable is reduced, and the antenna performance is optimized.
However, in practical applications, 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 feed cable are designed and produced and processed independently, and the integral design of the feed cable is not utilized;
secondly, in the use process of the feed cable, one or more choke rings need to be opened, and after the feed cable is placed into the choke rings, the choke rings are closed, 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 feed cable to play a role in restraining the common mode current, so that a large number of choke rings are required to be arranged on the feed cable, and the cost is increased;
fourthly, because the choke ring is small, the length of the feed cable which can be covered is short, so that the loss path is short, and the effect of restraining the common mode current is not ideal.

Detailed Description
Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application.
Currently, a feeder cable includes an inner core (signal line) and an outer core (shielding layer), and in the case of an antenna operation, as shown in fig. 1, energy is transmitted by 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, one or more choke rings are sleeved on the outer surface of a feeder cable, so that common-mode current on the outer surface of the feeder cable is lost by the choke rings, radiation of the feeder cable is reduced, and antenna performance is optimized.
However, in the use process of the feeder cable, as shown in fig. 3, one or more choke rings need to be opened, and the feeder cable is put into the choke ring, and then the choke ring is closed, which is complicated in process and not beneficial to the overall design. Moreover, a plurality of choke rings are required to be arranged according to the length of the feed cable to achieve the effect of suppressing the common mode current, so that a large number of choke rings need to be arranged on the feed cable, and the cost is increased. In addition, since the choke loop is small, the length of the power cable that can be covered is short, so that the loss path is short, and the effect of suppressing the common mode current is not desirable.
Therefore, the present application provides a transmission cable, mainly aiming at the technical problems existing in the prior art, such as complicated process, not favorable for overall design, high cost and unsatisfactory effect of suppressing common mode current.
The transmission cable of this application embodiment is through setting up the transmission line in the body to set up outer magnetic ring and/or interior magnetic core in the body, wherein, the transmission line sets up in the inside of outer magnetic ring, and interior magnetic core sets up the inside at the transmission line. Therefore, the external magnetic ring is arranged outside the transmission line and/or the internal magnetic core is arranged inside the transmission line, so that the energy transmission function and the common-mode current restraining function can be realized at the same time. And, set up inside transmission cable with outer magnetic ring and/or interior magnetic core, can avoid among the prior art in the in-process that uses the cable, frequently open the condition of choke ring, simplify the process, do benefit to transmission cable's overall design. In addition, the outer magnetic ring covers the outside of the transmission line, and the inner magnetic ring is located inside the transmission line, so that a loss path can be prolonged, and the suppression effect of common-mode current is effectively improved. In addition, a plurality of choke rings do not need to be arranged outside the transmission cable, and cost can be saved.
The transmission cable and the electronic apparatus of 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 present 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 arranged in the body, a first end of the transmission line 10 is connected with the antenna, and a second end of the transmission line 10 is connected with the radio frequency component.
The outer magnetic ring 20 and the inner magnetic core 30 are disposed 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.
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 is merely exemplified by the case where 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 by providing the transmission line 10 in the transmission cable 100, a transmission function of energy can be realized. The function of suppressing the common mode current outside the outer core (shielding layer) can be realized by providing the outer magnetic ring 20 in the transmission cable 100, and the function of suppressing the common mode current can also be realized by providing the inner magnetic core 30 in the transmission cable 100.
Specifically, by providing the transmission line 10, the outer magnetic ring 20 and/or the inner magnetic core 30, on the one hand, a high impedance can be formed to block the downward flow of the common mode current, and on the other hand, the common mode current that has flowed downward can be consumed by the transmission line 10 that is arranged in the outer magnetic ring 20 and has a long length. Therefore, the transmission cable 100 in the present application can suppress more common mode current flowing from the antenna to the transmission line 10 than a general feeder cable.
The transmission line 10 may be disposed in the transmission cable 100 in a spiral manner or a broken line 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 this application. Therefore, the longer transmission line 10 (for example, 1 meter) can be arranged in the shorter external magnetic ring 20 (for example, 10 centimeters), namely, the longer transmission line 10 is arranged in the very short external magnetic ring 20, so that the current loss path can be increased, the common-mode current can be consumed as much as possible, and the effect of effectively restraining the common-mode current can be achieved. In addition, the overall length of the transmission cable 100 can be reduced, and the transmission performance of the transmission cable can be ensured.
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, or the like. Fig. 4 is merely exemplified in that the transmission line 10 is 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 in a zigzag manner, 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 (shield layer), the above-mentioned inner portion of the transmission line 10 refers to the inner portion of the structure formed by the transmission line 10 as a whole, and the outer portion of the transmission line 10 refers to the outer portion of the structure formed by the transmission line 10 as a whole. As shown in fig. 5, the inner magnetic core 30 disposed inside the transmission line 10 refers to the inner magnetic core 30 disposed inside the spiral wound by the transmission line 10, and the outer magnetic ring 20 disposed outside the transmission line 10 refers to the outer magnetic ring 20 disposed outside the spiral wound by 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 magnetically lossy materials. Likewise, the inner magnetic core 300 of the transmission cable 100 is also made of a magnetic material, including but not limited to one or more of ferrite, wave-absorbing material, and other magnetically lossy materials.
As an example, in case that 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, and the external magnetic ring 20, an oblique sectional view, a side sectional view, and a top 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 penetrate out from two ends of the outer magnetic ring 20, wherein one end of the transmission line 10, which is denoted as a first end in this application, is connected to an antenna, for example, a radiation element of the antenna, and the other end of the transmission line 10, which is denoted as a second end in this application, is connected to other radio frequency components.
As another example, exemplified in that 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, and the internal magnetic core 30, an oblique sectional view, a side sectional view, and a top sectional view of the transmission cable 100 may be as shown in fig. 8. Wherein, the transmission line 10 is disposed outside the outer magnetic ring 20, a first end of the transmission line 10 is connected to an antenna, for example, a radiation element of the antenna, and a second end of the transmission line 10 is connected to other rf components.
As still another example, exemplified in that 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 magnetic ring 20, and the 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 disposed inside the outer magnetic ring 20, the inner magnetic core 30 is disposed inside the transmission line 10, a first end of the transmission line 10 is connected to an antenna, for example, a radiation 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 core 30 and the outer ring 20 inside and outside the transmission line 10, respectively, it is possible to play a role of better suppressing the common mode current.
The transmission cable 100 of the embodiment of the present application is configured 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, it is possible to simultaneously achieve a function of transmitting energy and a function of suppressing a common mode current. In addition, the outer magnetic ring 20 and/or the inner magnetic core 30 are/is arranged inside the transmission cable 100, so that the situation that a 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 located inside the transmission line 10, so that a loss path can be extended, and the suppression effect of the common mode current is effectively improved. In addition, there is no need to provide a plurality of choke rings outside the transmission cable 100, which can save cost.
In the embodiment of the present application, since the transmission line 10 can be disposed in the transmission cable 100 in a spiral and/or a zigzag manner, after the transmission line 10 is straightened, the linear length thereof is greater than that of the outer magnetic ring or greater than that of the inner magnetic core 30. For example, referring to fig. 7, the linear length of the transmission line 10 after straightening is greater than the linear length of the outer magnetic ring 20, and for example, referring to fig. 8, the linear length of the transmission line 10 after straightening is greater than the linear length of the inner magnetic core 30. Therefore, the longer transmission line 10 can be arranged in the shorter outer magnetic ring 20, namely, 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 can be consumed as much as possible, and the effect of effectively restraining the common-mode current can be achieved. Moreover, compared with the prior art in which a choke ring is sleeved on a very long feed cable, the feed cable has a large volume and cannot be applied in actual production, and the overall length of the transmission cable 100 can be greatly reduced, so that the transmission performance of the transmission cable is ensured.
It should be noted that the transmission line 10 and the external magnetic ring 20 may be disposed in a close fit, or a gap, which is referred to as a first gap in this application, may be disposed between the transmission line 10 and the external magnetic ring 20. That is, in the present application, the external magnetic ring 20 and the transmission line 10 need not to be interfered and overlapped, so as to ensure the transmission performance of the transmission cable 100 and ensure the suppression effect of the common mode current.
Similarly, the transmission line 10 and the inner magnetic ring 30 may be disposed in close fit, or a gap, referred to as a second gap in this application, may be disposed between the transmission line 10 and the inner magnetic ring 30. That is, in the present application, the inner magnetic ring 30 and the transmission line 10 need not be interfered with and overlapped, so as to ensure the transmission performance of the transmission cable 100 and ensure 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 magnetic ring 20, and the inner magnetic core 30, as shown in fig. 10, a first gap is provided between the outer magnetic ring 20 and the transmission line 10, and a second gap is provided between the inner magnetic core 30 and the transmission line 10.
As a possible implementation manner, the outer magnetic ring 10 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. Similarly, the inner magnetic ring 30 may be disposed in one layer or multiple layers in the transmission cable 100 to ensure the suppression effect of the common mode current. Fig. 4 is merely illustrative of providing one layer in the transmission cable 100 with the outer magnetic ring 10 and the inner magnetic ring 30.
As a possible implementation manner, the transmission line 10 in the transmission cable 100 may be a coaxial line, or may also be a microwave radio frequency transmission line, such as a microstrip line, a strip line, a waveguide, a coplanar waveguide, and the like.
As another possible implementation, the transmission line 10 in the transmission cable 100 may be one, or may also be multiple (e.g., coaxial line).
As an example, taking the transmission line 10 as an example of two coaxial lines, when the transmission cable 100 includes two transmission lines 10, an oblique sectional view, a side sectional view, and a top sectional view of the transmission cable 100 may be as shown in fig. 11.
