Embodiment Construction

[0096] The disclosure reduces the difficulty of assembly by designing the insulating porcelain as a multi-lobe structure. Further, the lead wires of the collector electrodes at all levels are drawn out from the small holes in the middle of the insulating porcelain flaps, which not only increases the insulation performance but also saves space. In the case of the inner diameter, the outer diameter of the collector is minimized to achieve high efficiency under miniaturization.

[0097] In order to make the purpose, technical solutions and advantages of the present disclosure clearer, the present disclosure will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0098] In an exemplary embodiment of the present disclosure, a lead-through type multi-stage buck collector is provided. figure 1 It is a cross-sectional view of a lead-through multi-stage buck collector according to an embodiment of the present...

Abstract

The present invention provides a lead internal breaking multi-stage depressed collector. The lead internal breaking multi-stage depressed collector comprises: M-stage collectors arranged in order; N insulation porcelain lobes commonly enclose an inner cylinder structure, a holding space is arranged the inner side of the inner cylinder structure, and the M-stage collectors are arranged in the holding space, wherein at least one of the N insulation porcelain lobes has an electrode lead hole, the electrode lead of one of the M-stage collectors is connected with the rail portion of the lead internal breaking multi-stage depressed collector through the electrode lead hole, and M and N are both integers being larger than 1. The lead internal breaking multi-stage depressed collector is led out from the lead hole at the middle of the insulation porcelain so as to increase the insulation performances between electrodes and between each electrode with the ground and save the space; and each electrode and the insulation porcelain are welded through adoption of solders, and the insulation porcelain and the outer cylinder are welded through adoption of the solders so as to increase soundness.

Description

technical field [0001] The present disclosure relates to the technical field of microwave electric vacuum devices, in particular to a miniaturized and light-weight lead-in-through multi-stage pressure-reducing collector. Background technique [0002] As a very important microwave power device, traveling wave tubes are widely used in electronic countermeasures because of their wide operating frequency (the bandwidth of several octaves can be easily obtained, which is suitable for electronic warfare), high output power and high efficiency. , electronic warfare, radar, meteorological observation, space measurement and satellite communication and other fields. In general, various applications have different requirements for devices such as traveling wave tubes. However, in general, higher power and higher efficiency are common trends in various applications. Especially for space traveling wave tubes for space measurement and satellite communication, due to the limited energy s...
