Summary of the invention
The purpose of this utility model is to provide a kind of aluminum-housed resistor sealed port of butt end structure that internal particle filler can be avoided to spill.
In order to achieve the above object, the utility model provides a kind of aluminum-housed resistor sealed port of butt end structure, the granule filler comprising aluminium shell and be located in aluminium shell, it is characterized in that, the two ends of described aluminium shell are provided with through hole, be provided with silicon rubber and sealing porcelain piece in described through hole, granule filler can be encapsulated in aluminium shell by described silicon rubber, and sealing porcelain piece is fixed on outside silicon rubber.
Preferably, the surrounding of described through hole is provided with multiple press flute, and the deformation that described press flute enables aluminium shell produce by the extruding of sealing porcelain piece firmly.
Preferably, described aluminum-housed resistor sealed port of butt end structure also comprises high temperature wire, and high temperature wire one end is located in aluminium shell, and the other end is located at outside aluminium shell through silicon rubber and sealing porcelain piece.
Preferably, also resistive element is provided with in described aluminium shell.
Preferably, described sealing porcelain piece is 95 porcelain.
Preferably, described silicon rubber is high temperature silicone rubber.
Compared with prior art, the beneficial effects of the utility model are:
Aluminum-housed resistor sealed port of butt end structure of the present utility model, adopts silicon rubber to add sealing porcelain piece press flute structure, aluminium enclosure granule filler is encapsulated in inside.With existing filled stone sand and silicones mixture structure, pour into compared with high-temperature cement structure, structure is simple, easy to operate, fundamentally ensure that product all there will not be end face to ftracture under any operating mode, granule filler is caused to spill, affect periphery electric device, fundamentally improve the degree of protection of product, go for all aluminum-housed resistors.
Accompanying drawing explanation
Fig. 1 is aluminum-housed resistor sealed port of butt end structural blast view.
Embodiment
Below in conjunction with specific embodiment, set forth the utility model further.Should be understood that these embodiments are only not used in restriction scope of the present utility model for illustration of the utility model.In addition should be understood that those skilled in the art can make various changes or modifications the utility model, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the utility model instruction.
Embodiment
As shown in Figure 1, for aluminum-housed resistor sealed port of butt end structural blast view, described aluminum-housed resistor sealed port of butt end structure, comprising aluminium shell 1 and being located in aluminium shell 1 take mica sheet as resistive element and the granule filler of skeleton, the two ends of described aluminium shell 1 are provided with through hole, be provided with silicon rubber 4 and sealing porcelain piece 2 in described through hole, granule filler can be encapsulated in aluminium shell 1 by described silicon rubber 4, ensure aluminium shell 1 inside granule filler cannot leakage current out.Sealing porcelain piece 2 is fixed on outside silicon rubber 4.
The surrounding of described through hole is provided with multiple press flute 5, and sealing porcelain piece 2 extrudes firmly by the deformation that described press flute 5 enables aluminium shell 1 produce, and makes that sealing porcelain piece 2 is fixed on outside silicon rubber 4, aluminium shell 1 two ends.Described aluminum-housed resistor sealed port of butt end structure also comprises high temperature wire 3, and high temperature wire 3 one end is located in aluminium shell 1, and the other end is located at outside aluminium shell 1 through silicon rubber 4 and sealing porcelain piece 2.
During making, by band high temperature wire 3 is that the resistive element of skeleton is placed behind aluminium shell 1 inside with mica sheet, granule filler is filled with in the through hole of aluminium shell 1 end face, then in the through hole of end face, colloidal silicon rubber 4 is coated, after silicon rubber 4 dries in the shade naturally, sealing porcelain piece 2 is buckled in the through hole of aluminium shell 1 end face, finally by mould at aluminium shell 1 surrounding press flute 5, object is that aluminium shell 1 produces deformation and makes sealing porcelain piece 2 firm at Inner extrusion, prevents sealing porcelain piece 2 from coming off.
Compared to prior art, the aluminum-housed resistor sealed port of butt end structure that the utility model provides, adopt silicon rubber to be encapsulated by internal particle filler, then fixed by porcelain piece again, structure is simple, and easy to operate, product degree of protection is high, is applicable to all aluminum-housed resistors.
Although the utility model discloses as above with preferred embodiment; so itself and be not used to limit the utility model; any those skilled in the art; not departing from spirit and scope of the present utility model; when doing a little amendment and perfect, therefore protection range of the present utility model is when being as the criterion of defining with claims.
