The micro-wave oven earthing or grounding means
Technical field
The utility model relates to a kind of micro-wave oven earthing or grounding means, belongs to the improvement technology of micro-wave oven earthing or grounding means.
Background technology
Existing micro-wave oven earthing or grounding means structure as shown in Figure 1, plate 10 tops are provided with installing hole 100 behind the body of heater, power line 2 is provided with the ground terminal 20 of band through hole, and screw 3 passes the through hole on packing ring 4, the ground terminal 20, is fastened in the installing hole 100 on the plate of back, ground terminal 20 is fixed on the plate 10 of back, realize the ground connection of micro-wave oven, but plate be the metallic plate that approaches behind the above-mentioned body of heater, screw is fixedly the time, be prone to skidding, can reduce the ground connection performance of micro-wave oven.
The utility model content
It is a kind of simple in structure that the purpose of this utility model is to provide, and can guarantee the micro-wave oven earthing or grounding means of ground connection effect, to overcome weak point of the prior art.
A kind of micro-wave oven earthing or grounding means by this purpose design comprises body of heater and power line, and power line is provided with ground terminal, and its architectural feature is that above-mentioned ground terminal is installed on the body of heater top board by screw.
Above-mentioned ground terminal is packed in the position that is connected with side plate on the body of heater top board by screw.
The utility model is because the employing ground terminal is installed in the structure on the body of heater top board, and strength of roof is stronger, and screw is difficult for skidding, and therefore, it is not only simple in structure, and can guarantee the ground connection effect.
