Abstract
The utility model discloses a U-shaped waveguide rotary joint which comprises a flange I (1), a circular waveguide I (2), a flange base (3), a circular waveguide II (4) and a flange II (5) which are sequentially connected, wherein the U-shaped waveguide rotary joint is integrally shaped like a U, the circular waveguide I (2) is arranged on the side surface of the flange base (3), the circular waveguide II (4) is arranged on the other side surface of the flange base (3), the flange I (1) is arranged on the circular waveguide I (2), the flange II (5) is arranged on the circular waveguide II (4), and inner cavities of the circular waveguide I (2) and the circular waveguide II (4) are hollow cylinders. The U-shaped waveguide rotary joint has the beneficial effects of no longitudinal current, excellent electric connection performance, and the like, and is easy to machine.
Description
Technical field
The utility model relates to microwave component technical field, particularly a kind of U-shaped waveguide junction.
Background technology
Waveguide is in microwave rotary joint, to be used for the critical component of guide electromagnetic waves.Generally mention waveguide and just refer to hollow metal tube.Waveguide cross sectional shape is generally hollow, rectangular shape, and waveguide tube wall generally adopts the metals such as copper aluminium to make.This rectangular waveguide machine work precision is difficult to guarantee, processes more difficult.There is decay in microwave, decay is comprised of two parts in rectangular waveguide conductive process: a part claims longitudinal current decay, and another part claims transverse current decay.When increasing microwave frequency, decay is risen very fast in rectangular waveguide, and transverse electric size strengthens, and transverse current is reduced, and longitudinally decay increases on the contrary, has great contradiction, can increase on the contrary the power loss of microwave.
Utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, provides a kind of and is easy to U-shaped waveguide junction without longitudinal current, electrical connection properties ideal, machine work.
The purpose of this utility model is achieved through the following technical solutions: a kind of U-shaped waveguide junction, it comprises ring flange one, circular waveguide one, flange seat, circular waveguide two and the ring flange two connecting successively, integral body is U word shape, circular waveguide one is arranged on the side of flange seat, circular waveguide two is arranged on the another side of flange seat, ring flange one is arranged on circular waveguide one, ring flange two is arranged on circular waveguide two, and the inner chamber of circular waveguide one and circular waveguide two is hollow cylindrical.
Described ring flange one is arranged on the top of circular waveguide one, and ring flange two is arranged on the top of circular waveguide two.
Described circular waveguide one is arranged on the left side of flange seat, and circular waveguide two is arranged on the right side of flange seat.
The utlity model has following advantage: (1) circular waveguide one of the present utility model and circular waveguide two inner chambers are hollow cylindrical structure, can not produce longitudinal current, thereby when wave frequency increases, decay reduce, and have reduced the loss of microwave power.(2), from mechanics and stress equilibrium angle, processing circular waveguide is more favourable, surpasses rectangular waveguide one raise for aspects such as error and convenience.(3) top of circular waveguide one and circular waveguide two is separately installed with ring flange one and ring flange two, easy for installation, easy to manufacture, and electrical connection properties obviously improves simultaneously.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is vertical view of the present utility model;
Fig. 3 is left view of the present utility model;
In figure, 1-ring flange one, 2-circular waveguide one, 3-flange seat, 4-circular waveguide two, 5-ring flange two.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described, protection range of the present utility model is not limited to the following stated:
As Figure 1-3, a kind of U-shaped waveguide junction, it comprises ring flange 1, circular waveguide 1, flange seat 3, circular waveguide 24 and the ring flange 25 connecting successively, integral body is U word shape, circular waveguide 1 is arranged on the side of flange seat 3, and circular waveguide 24 is arranged on the another side of flange seat 3, and ring flange 1 is arranged on circular waveguide 1, ring flange 25 is arranged on circular waveguide 24, and the inner chamber of circular waveguide 1 and circular waveguide 24 is hollow cylindrical.
As depicted in figs. 1 and 2, ring flange 1 is arranged on the top of circular waveguide 1, and ring flange 25 is arranged on the top of circular waveguide 24.Circular waveguide 1 is arranged on the left side of flange seat 3, and circular waveguide 24 is arranged on the right side of flange seat 3.The relative circular waveguide 24 of circular waveguide 1 is done rotatablely moving of 360 degree, first microwave enters in circular waveguide 24, as the direction of arrow in Fig. 1 is depicted as the Way in of microwave, then microwave spreads out of from the port of circular waveguide 1, when increasing microwave frequency, laterally reduce, and do not have longitudinal decay, reduced the loss of microwave power.One top of circular waveguide 1 and circular waveguide 24 is separately installed with ring flange 1 and ring flange 25, has improved electrical connection properties.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also do some improvement and replacement, these improvement and replacement also should be considered as protection range of the present utility model.
