Abstract
The utility model discloses radio-frequency transmission line. The radio-frequency transmission line is characterized in that: the radio-frequency transmission line comprises a conductor and an insulator, wherein the insulator is coated outside the conductor, and the insulator is sleeved with at least one magnet ring. Since the insulator is sleeved with the magnet ring(s), the transmission line is capable of greatly reducing microwave loss of the radio-frequency connection line; when the transmission line is used as a common mode choking coil, signal distortion does not happen; and the operation is convenient with the corresponding magnet ring(s) directly sleeved on the insulator.
Description
Technical field
The utility model relates to a kind of radio-frequency transmission line.
Background technology
Radio-frequency transmission line is important electrical connection, is mainly used in the transmission of the signal of telecommunication.The electromagnetic loss of radio-frequency transmission line is very serious, and especially in the electronic device wiring very dense, electromagnetic wave loss and interference are all very serious.To solve electromagnetic wave loss problem by in the radio-frequency transmission line outside, increasing wire sheathing at present.But the shield effectiveness that the count of wire sheathing does not have very little.
The utility model content
The purpose of this utility model is in order to overcome deficiency of the prior art, and a kind of radio-frequency transmission line that can reduce the electromagnetic wave loss, strengthen function of shielding is provided.
For realizing above purpose, the utility model is achieved through the following technical solutions:
Radio-frequency transmission line, is characterized in that, comprises conductor and insulator, and described insulator is coated on all sides of described conductor, is arranged with at least one magnet ring on described insulator.
Preferably, described magnet ring is the manganese-zinc ferrite magnet ring.
Preferably, described conductor comprises the first conductor and the second conductor, described insulator comprises the first insulator and the second insulator, described the first insulator is set on described the first conductor, described the second conductor is set on described the first insulator, and described the second insulator is set on described the second conductor.
Preferably, described the first conductor, the second conductor, the first insulator and the second insulator coaxial line ground arrange.
The utility model radio-frequency transmission line, by sheathed magnet ring outside insulator, can reduce the lossy microwave of radio frequency connecting line greatly; While as common mode choke, using, can not cause distorted signals; Easy to operate, corresponding magnet ring directly is enclosed within on insulator and gets final product.The utility model radio-frequency transmission line is particularly useful for testing with very denses such as cable and electronic device wirings, and the occasion very high to semaphore request.
Description of drawings
Fig. 1 is the structural representation of the utility model radio-frequency transmission line.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail: as shown in Figure 1: radio-frequency transmission line comprises conductor and insulator.Insulator is coated on all sides of conductor.Be arranged with at least one row's magnet ring 5 on insulator.Magnet ring 5 is manganese-zinc ferrite magnet rings.
Conductor comprises the first conductor 1 and the second conductor 2.Insulator is wire sheathing, and it comprises the first insulator 3 and the second insulator 4.The first conductor 1, the second conductor 2, the first insulator 3 and the second insulator 4 coaxial line ground arrange.The first insulator 3 is set on the first conductor 1.The second conductor 2 is set on the first insulator 3.The second insulator 4 is set on the second conductor 2.
The utility model radio-frequency transmission line, by sheathed magnet ring outside insulator, can reduce the lossy microwave of radio frequency connecting line greatly; While as common mode choke, using, can not cause distorted signals; Easy to operate, corresponding magnet ring directly is enclosed within on insulator and gets final product.The utility model radio-frequency transmission line is particularly useful for testing with very denses such as cable and electronic device wirings, and the occasion very high to semaphore request.
Embodiment in the utility model only is used for the utility model is described, and does not form the restriction to the claim scope, and other substituting of being equal in fact that those skilled in that art can expect, all in the utility model protection range.
