Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of power transmission, in particular to a phase-adjustable waveguide component. Background Art
[0002] At present, there are many uncontrollable factors in the cable manufacturing process. If a large phase error is found when the cable is completed, a long cable can be cut off to reduce the length, but if the cable is short, the cable is basically scrapped, wasting materials.
[0003] At present, it is difficult to cut off a part of the cable by welding. First, the bushing and inner conductor of the cable must be removed. However, for high-frequency and high-precision cable matching, the bushing and inner conductor removal must be repeated many times. Long-term high-temperature welding of the cable will cause a certain degree of damage to the cable, and it is very difficult to cut the cable manually for high-precision matching.
[0004] At present, the phase-matching cables are generally only suitable for frequency bands within 3 GHz. Taking the XFWP-3507 cable as an example, at 3 GHz, the phase difference of 1 mm error is about 10°. The higher the frequency, the greater the phase difference. It can be seen that the original phase-matching method is difficult to achieve under high frequency and high phase requirements.
[0005] At present, the phase matching cable is basically made into a section first, and the phase of the cable is checked with a network test analyzer. It is necessary to check the phase multiple times, and the operation process is cumbersome. Summary of the invention
[0006] The utility model aims to provide a phase-adjustable waveguide component to solve the problem of increasing the cable length to adjust the cable limit proposed in the above background technology.
[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0008] A phase-adjustable waveguide component comprises a front joint assembly, a rear joint assembly and a shell, wherein the front joint assembly is pressed into the shell to form a front half of the joint, and the rear joint assembly is pressed into the shell to form a rear half of the joint, and the rear half of the joint is rotated into a front nut with the rear joint assembly, wherein a nut is connected to the outer sleeve of the rear joint assembly between the shell and the front nut, and a rear nut is also arranged on the rear side of the front nut.
[0009] Preferably, the front joint as a whole comprises a joint male inner conductor, a first joint insulator, and a first joint sleeve; the first joint insulator is cut and inserted into the joint male inner conductor, and is integrally inserted into the first joint sleeve.
[0010] Preferably, the rear joint as a whole comprises a joint female inner conductor, a second joint insulator, and a second joint sleeve; the second joint insulator is cut and inserted into the joint female inner conductor, and is integrally inserted into the second joint sleeve.
[0011] Preferably, the female inner conductor of the joint is connected to the outer shell with the second joint insulator, and the second joint sleeve is connected to the front nut through the joint welding cup.

[0013] Compared with the commonly used method, in the structure of the present invention, the overall length is increased by rotating the shell, thereby adjusting the phase. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] See also Figure 1-3 , an embodiment provided by the utility model:
[0020] A phase-adjustable waveguide component comprises a front joint assembly 1, a rear joint assembly 2 and a shell 3, wherein the front joint assembly 1 is pressed into the shell 3 to form a front half of the joint, and the rear joint assembly 2 is pressed into the shell 3 to form a rear half of the joint, and the rear half of the joint is rotated into a front nut 4 with the rear joint assembly 2, wherein a nut 5 is connected to the outer sleeve of the rear joint assembly 2 between the shell 3 and the front nut 4, and a rear nut 6 is also arranged on the rear side of the front nut 4.
[0021] like Figure 2 As shown: press the front connector as a whole 1 into the housing 3, press the front end of the rear connector as a whole 2 into the housing 3, and insert the rear end as a whole into the front nut 4, and then turn the housing 3, nut 5, and rear nut 6 into the front nut 4 in sequence to form a whole, and then weld the cable for use.
[0022] like Figure 1-2 As shown: the front joint as a whole 1 includes a joint male inner conductor 11, a first joint insulator 12, and a first joint sleeve 13. The first joint insulator 12 is cut and inserted into the joint male inner conductor 11, and is inserted into the first joint sleeve 13 as a whole.
[0023] The rear joint as a whole 2 comprises a joint female inner conductor 21 , a second joint insulator 22 , and a second joint sleeve 23 . The second joint insulator 22 is cut and inserted into the joint female inner conductor 21 , and is inserted into the second joint sleeve 23 as a whole.
[0024] The first joint insulator 12 is cut open, inserted into the slot of the male inner conductor 11 of the joint, and inserted as a whole into the first joint sleeve 13, and then the whole is pressed into the outer shell 3 to form the front half of the joint; the back half of the joint is formed by cutting the second joint insulator 22, inserting it into the slot of the female inner conductor 21 of the joint, and then inserting the whole into the second joint sleeve 23, the front half of the whole is transferred into the outer shell 3 to connect with the first joint sleeve 13, and the back half is transferred into the front nut 4.
[0025] The female inner conductor 21 of the joint is connected to the housing 3 with the second joint insulator 22, and the second joint sleeve 23 is connected to the front nut 4 through the joint welding cup 7. Since the front nut 4 is also connected to the rear nut 6, it is used for connecting cables.
[0026] Compared with the commonly used method, this method of connecting cables saves more time. When in use, the overall length is increased by rotating the outer shell 3 to adjust the phase. In the adjustable phase waveguide component of the utility model, the front joint as a whole 1 and the rear joint as a whole 2 can be directly welded to any end of the cable, and then the phase of the cable can be checked. The connector of the utility model can adjust the cable with a small phase, and there is no need to weld the bushing and the inner conductor multiple times, which provides a certain degree of protection for the cable.
