Embodiment Construction

[0033] In order to further understand the content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:

[0034] image 3 It is a vertical sectional view of the magnetron with the structure of the present invention, with the antenna cover disassembled. Figure 4 is a partial schematic view of an antenna cover utilizing the present invention. As shown in the figure, the basic structure constituting the magnetron is the same as that of conventional ones, and the same symbols are assigned to the same parts, and detailed description thereof will be omitted.

[0035] In the present invention, a bolt portion (101) is formed on the outer surface of the exhaust pipe (19), and on the inner side of the antenna cover (42) combined with the exhaust pipe (19), a bolt portion (101) that can be connected to the bolt portion (101) is formed. ) of the nut part (102), so ...

Abstract

Th present invention relates to an antenna cover mounting structure of magnetrocontrolled electronic tube, and is characterized by that in the magnetrocotrolled electronic tube with wrapped exhaust tube connected antenna cover, on the external circumferential surface of the exhaust tube a bolt portion is formed, and on the internal circumferential surface of the antenna cover a nut portion is formed. At the same time of mounting the antenna cover on the exhaust tube in the screw-connecting mode, in order to obtain the impedance matching the height of antenna cover can be regulated, so that it can make one kind of antenna cover be suitable for several kinds of magnetro controlled electronic tubes, therefore the common use of its component can reduce production cost.

Description

technical field [0001] The invention belongs to magnetron electron tubes, in particular to an antenna cover installation structure suitable for various magnetron electron tubes. Background technique [0002] Generally, as we all know, magnetron tubes are installed on electronic radars or lighting appliances, etc., and convert electrical energy into high-frequency energy like microwaves. [0003] Such as figure 1 As shown in FIG. 1 , a simple description will be given below for a magnetron of a conventional general structure. [0004] On the inner side of the upper yoke (1a) and the lower yoke (1b) formed into a zigzag yoke (1), a cylindrical anode cylinder (2) made of copper tubes or the like is installed. Inside the cylinder (2), there are organic high-frequency components, and multiple vanes (3) forming a common resonator are arranged at the same intervals toward the axis. And, on the front end side of its blade (3), its upper and lower parts are connected with the inne...
