Problems solved by technology

The assembly line is adjusted separately for different types of upper yoke plates, which also increases production costs and technical requirements
And now the assembly method of the upper yoke plate and the lower yoke plate uses the press-fit method, which leads to great inconvenience in disassembly and assembly in later inspection and maintenance

Abstract

The invention discloses an upper yoke plate structure of a magnetron of a microwave oven, which comprises an upper yoke plate body and a projected sheet, wherein the center of the upper yoke plate is provided with a microwave energy output device installing hole, a hanging hole is arranged on the projected sheet, and the upper yoke plate is an upper yoke plate which can select two side edges to be combined with a lower yoke plate of the magnetron as required. Through the adoption of the upper yoke plate structure of the magnetron of the invention, the standard unionization of the magnetron can be realized, the confusion caused by human factors in the transportation process can be effectively reduced, and different models do not need to be distinguished again in the assembling process.

Description

technical field [0001] The invention relates to an upper yoke plate structure of a microwave oven magnetron, in particular to a standardized upper yoke plate structure of a microwave oven magnetron. Background technique [0002] Generally speaking, a magnetron is an electronic device that can convert electrical energy into microwave electromagnetic energy, and is mainly used in microwave ovens or lighting appliances. figure 1 It is an oblique view of the components of the microwave oven magnetron in the prior art. This prior art magnetron includes a "mouth"-shaped yoke iron 22, which is formed by combining an upper yoke plate 20 and a lower yoke plate 2; the upper yoke plate 20 has four protruding ends 3, wherein the upper yoke plate 20 The main body 1 of the yoke plate is provided with a suspension hole 6, which is used to pre-position the magnetron when the magnetron is installed in the waveguide; the main body 1 of the upper yoke plate is also provided with a reinforcing...
