Abstract
The utility model belongs to an improvement of a transformer, in particular to the improvement of a transformer for micro-wave oven, which mainly comprises an I/E-type iron core, a branch iron core, a filament coil, a primary and a secondary coils, and is characterized in that: the outer surface of a module formed by the I/E-type iron cores has a matched slot for a base plate of micro-wave oven. The utility model is characterized by the connecting mode of the transformer for the micro-wave oven being changed from the base plate thread connection into the direct plug-in mode, thereby saving the consumption of base plate material, and saving one weld procedure, saving man-power and materials, and enhancing the market competition of the micro-wave oven with easy installation.
Description
Technical field
The utility model belongs to the improvement of transformer, relates in particular to a kind of improvement of microwave oven transformer.
Background technology
The transformer that known microwave oven uses is to weld a base plate with four solder joints on transformer with the external member connected mode, base plate again with the microwave oven main body on base plate be connected with screw.And the shortcoming of this kind connected mode: one increases by one welding sequence for need still welding of installation in a base plate and the production technology, so improved production raw material and manufacturing cost, cause the unit price of waste of material and microwave oven to raise, it two is after transformer is installed on the microwave oven, the microwave oven complete machine is when the destructive test of test drop test or other every safety indexs, after microwave oven is clashed into, make the bottom deformation on the transformer, cause transformer and microwave oven inwall to be close to, cause the bad result of short circuit or shell damage.
The utility model content
The purpose of this utility model is to improve the connecting mode of micro-wave oven transformer, adopts the plug-in type mode of directly installing, and a kind of improvement of microwave oven transformer is provided.
For realizing the purpose of this utility model, the technical scheme that adopts is, a kind of improvement of microwave oven transformer, mainly by I/E font iron core, along separate routes iron core, heater winding, once reach secondary coil and form, it is characterized in that module outer surface that described I/E font iron core constitutes is provided with the slot with the grafting of micro-wave oven baseboard coupling.
Described slot can be provided with arbitrarily in any setting of module upper and lower surface of I sections core and E sections type formation or in its two sides respectively.
Module upper surface that described slot can be respectively constitutes in I sections core and E sections type and side or be provided with arbitrarily at lower surface and side.
The cross sectional shape of described slot is not limited only to rectangle, V-type, arc.
Distinguishing feature of the present utility model is the micro-wave oven transformer connecting mode to be connected by bottom plate screw change direct plug-in type installation into, has promptly saved baseboard material, can save one welding sequence again, labor and material saving, it was both convenient, firm again to install, and had then strengthened the competitiveness of microwave oven on market.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Execution mode
Below in conjunction with drawings and Examples structure of the present utility model is further described.
With reference to accompanying drawing, a kind of improvement of microwave oven transformer, mainly by I/E font iron core 1, along separate routes iron core 2, heater winding 3, once reach secondary coil 4,5 and form, it is characterized in that four avris on the module outer surface that described I/E font iron core constitutes are provided with the slot 6 with the grafting of micro-wave oven baseboard coupling.The cross sectional shape of slot is not limited only to rectangle, V-type or arc according to needs are installed, and can be any grafting shape.The module upper and lower surface avris that slot also can be respectively constitutes at I sections core and E sections core be provided with arbitrarily or be provided with arbitrarily or be provided with arbitrarily in upper surface and side or in module lower surface and side in its two sides with the corresponding grafting of micro-wave oven baseboard coupling.Architecture advances of the present utility model also can be applicable to the transformer that uses on other electrical equipment.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
Claims (4)
1, a kind of improvement of microwave oven transformer, mainly by I/E font iron core, along separate routes iron core, heater winding, once reach secondary coil and form, it is characterized in that module outer surface that described I/E font iron core constitutes is provided with the slot with the grafting of micro-wave oven baseboard coupling.
2, the improvement of microwave oven transformer according to claim 1 is characterized in that described slot can be provided with arbitrarily in any setting of module upper and lower surface of I sections core and E sections type formation or in its two sides respectively.
