Abstract
A high-voltage transformer bushing for microwave oven comprises a lamp filament wire which extends out from two ends of the transformer and is exposed in the air, an insulating paint layer is coated on the surface of the lamp filament wire, and a bushing is wrapped outside the lamp filament wire. The sleeve is an inner glue outer fiber tube with an inner layer being a silicone tube and an outer layer being a glass fiber tube. The utility model wraps the sleeve outside the filament wire of the high voltage transformer for the microwave oven, and separates the filament wire from other metals by the sleeve; the lamp wire is ensured to be not contacted with other metals even if the lamp wire is bent for many times in the installation process of the transformer, the surface insulating paint layer is provided with pinholes to expose the wire core. Greatly improves the insulation effect, basically avoids the phenomena of electric leakage and ignition, and ensures the safe use of the microwave oven.
Description
Technical field
The utility model relates to a kind of bushing shell for transformer, particularly the high-tension transformer for microwave oven sleeve pipe.
Background technology
Referring to Fig. 1-shown in Figure 2, filament wire 2 is stretched from the two ends of the high-tension transformer 1 of microwave oven.Transformer has the process of dipping lacquer when producing, after accomplishing operations such as dipping lacquer, oven dry, expose the filament wire meeting hardening outside transformer; And transformer is in the process of installing, because installations needs, filament wire can be by repeatedly bending, thus cause the surperficial insulation enamelled coating of filament wire crack or pin hole to occur easily, thus core is exposed.Because the position of filament wire in microwave oven makes it be prone to contact with other metalwork, in case after crack or pin hole appearred in filament wire surface insulation enamelled coating, exposed core contacted with other metal the electric leakage accident will take place, thus dangerous people's the security of the lives and property.Therefore, need do further improvement.
The utility model content
The purpose of the utility model aims to provide a kind of simplicity of design, high-tension transformer for microwave oven sleeve pipe rational in infrastructure, safe in utilization, to overcome weak point of the prior art.
A kind of high-tension transformer for microwave oven sleeve pipe by this purpose design comprises filament wire, and filament wire is stretched from the two ends of transformer, and the surface scribbles the insulating varnish layer, and its architectural feature is that filament wire is wrapped with sleeve pipe.
Said sleeve pipe is the outer fine pipe of interior glue, and its internal layer is that silicone tube, skin are fiberglass tubes.
Two-layerly inside and outside the said sleeve pipe be split setting or be wholely set.
One or more snippets of said filament wire wrapped up by sleeve pipe.
The utility model is the filament wire outerwrap sleeve pipe at high-tension transformer for microwave oven, with sleeve pipe filament wire and other metal is separated; Even to guarantee that filament wire because of the repeatedly bending of transformer in installation process, makes core exposed and cause the surface insulation enamelled coating pin hole to occur, exposed core also can not contact with other metal.Improve insulation effect greatly, stopped electric leakage and spark phenomenon basically, ensured the safe handling of microwave oven.
Description of drawings
Fig. 1 is the structural representation of prior art high-tension transformer for microwave oven.
Fig. 2 is the profile of prior art filament wire.
Fig. 3 is the structural representation of the utility model one embodiment.
Fig. 4 is the profile that an embodiment wraps up the filament wire of sleeve pipe.
Among the figure: 1 is transformer, and 2 is filament wire, and 2.1 is core, and 2.2 are the insulation enamelled coating,, 3 is sleeve pipe, and 3.1 is silicone tube, and 3.2 is fiberglass tubes.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Referring to Fig. 3-Fig. 4, a kind of high-tension transformer for microwave oven sleeve pipe comprises filament wire 2, and filament wire is stretched from the two ends of transformer 1, and its surface scribbles insulating varnish layer 2.2.Be wrapped with sleeve pipe 3 in filament wire 2; Sleeve pipe is the outer fine pipe of interior glue, and its internal layer is that silicone tube 3.1, skin are fiberglass tubes 3.2.Pipe box 3 is after transformer 1 is accomplished the dipping lacquer operation, again on the filament wire 2 of parcel.
Owing in the installation process of transformer 1, the filament wire 2 of exposing outside transformer 1 can be prone to cause because of pin hole appears in filament wire 2 surperficial insulation enamelled coatings 2.2 core 2.1 is exposed by repeatedly bending; Again because the position of filament wire 2 in microwave oven is prone to contact with other metalwork, so, just the electric leakage accident can take place in case exposed core 2.1 contacts with other metalwork.In the present embodiment; For preventing the generation of this type of accident, the filament wire 2 of in microwave oven, having used the pipe box 3 of insulating effect to stretch from transformer 1 two ends is wrapped up respectively, even the insulation enamelled coatings 2.2 on filament wire 2 surfaces are exposed with core 2.1 because of pin hole occurring; But because there is sleeve pipe 3 that filament wire is wrapped up; Exposed core 2.1 can't be contacted with other metalwork, just can stop the generation of electric leakage accident basically, thereby ensured in use safe and reliable of microwave oven.
