Abstract
The invention provides an end surface sealing structure of an aluminum housing resistor. The end surface sealing structure comprises an aluminum housing and particulate filler in the aluminum housing and is characterized in that through holes are formed in the two ends of the aluminum housing and are internally provided with silicone rubber and sealing ceramic pieces, the particulate filler can be encapsulated in the aluminum housing through the silicone rubber, and the sealing ceramic pieces are fixed on the outer sides of the silicone rubber. According to the end surface sealing structure of the aluminum housing resistor, groove structures are formed by the silicone rubber and the sealing ceramic pieces by pressing, and the particulate filler is encapsulated in the aluminum housing. Compared with a structure filled with a mixture of quartz sand and silicon resin or a structure in which high-temperature cement is poured, the end surface sealing structure is simple, is convenient to operate, and can radically guarantee that at any working condition, the end surfaces of the aluminum housing resistor cannot crack, the particulate filler does not leak, peripheral electric appliances are not influenced, and thus the protection grade of the aluminum housing resistor is improved fundamentally. The end surface sealing structure is applicable to all aluminum housing resistors.
Description
Technical field
The present invention relates to power electric component field, relate in particular to a kind of aluminum-housed resistor sealed port of butt end structure.
Background technology
At present, the high-power aluminum casing resistor (high-temperature cement resistance) of selling on market, sealing two ends technique is common is: fill quartz sand and silicones mixture structure, perfusion high-temperature cement structure, and there is certain risk in above two kinds of structures, be summarized as follows: (1) fills quartz sand and silicones mixture structure is shaking under operating mode, the inner silicones high temperature ageing of end face quartz sand, there will be cracking, thereby cause internal particle filler to spill, damage of product also affects periphery electric device.(2) perfusion high-temperature cement structure operation complexity there will be equally end face cracking, thereby causes internal particle filler to spill under vibrations operating mode, and damage of product also affects periphery electric device.
Summary of the invention
The object of this invention is to provide a kind of aluminum-housed resistor sealed port of butt end structure that can avoid internal particle filler to spill.
In order to achieve the above object, the invention provides a kind of aluminum-housed resistor sealed port of butt end structure, comprise aluminium shell and be located at the granule filler in aluminium shell, it is characterized in that, the two ends of described aluminium shell are provided with through hole, in described through hole, be provided with silicon rubber and sealing porcelain piece, described silicon rubber can be encapsulated in granule filler in aluminium shell, and sealing porcelain piece is fixed on silicon rubber outside.
Preferably, the surrounding of described through hole is provided with multiple press flutes, and described press flute can push sealing porcelain piece firmly the deformation that aluminium shell produces.
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, in described aluminium shell, be also provided with resistive element.
Preferably, described sealing porcelain piece is 95 porcelain.
Preferably, described silicon rubber is high temperature silicon rubber.
Compared with prior art, the invention has the beneficial effects as follows:
Aluminum-housed resistor sealed port of butt end structure of the present invention, adopts silicon rubber to add sealing porcelain piece press flute structure, and aluminium enclosure granule filler is encapsulated in to inside.Compared with existing filling quartz sand and silicones mixture structure, perfusion high-temperature cement structure, simple in structure, easy to operate, fundamentally ensure that product all there will not be end face cracking under any operating mode, cause granule filler to spill, affect periphery electric device, fundamentally improved the degree of protection of product, go for all aluminum-housed resistors.
Brief description of the drawings
Fig. 1 is aluminum-housed resistor sealed port of butt end structure explosive view.
Embodiment
Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiment are only not used in and limit the scope of the invention for the present invention is described.In addition should be understood that those skilled in the art can make various changes or modifications the present invention after having read the content of the present invention's instruction, these equivalent form of values fall within the application's appended claims limited range equally.
Embodiment
As shown in Figure 1, for aluminum-housed resistor sealed port of butt end structure explosive view, described aluminum-housed resistor sealed port of butt end structure, comprise aluminium shell 1 and be located at the resistive element taking mica sheet as skeleton and the granule filler in aluminium shell 1, the two ends of described aluminium shell 1 are provided with through hole, in described through hole, be provided with silicon rubber 4 and sealing porcelain piece 2, described silicon rubber 4 can be encapsulated in granule filler in aluminium shell 1, ensure the granule filler of aluminium shell 1 inside cannot leakage current out.Sealing porcelain piece 2 is fixed on silicon rubber 4 outsides.
The surrounding of described through hole is provided with multiple press flutes 5, and described press flute 5 can push sealing porcelain piece 2 firmly the deformation that aluminium shell 1 produces, and makes to seal porcelain piece 2 and is fixed on silicon rubber 4 outsides, 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 are 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.
When making, to place behind aluminium shell 1 inside with the resistive element taking mica sheet as skeleton of high temperature wire 3, in the through hole of aluminium shell 1 end face, fill with granule filler, then in the through hole of end face, coat colloid silicon rubber 4, 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 to seal porcelain piece 2 in inside extruding firmly, prevents from sealing porcelain piece 2 and comes off.
Compared to prior art, aluminum-housed resistor sealed port of butt end structure provided by the invention, adopts silicon rubber by the encapsulation of internal particle filler, then fixes by porcelain piece again, and simple in structure, easy to operate, product degree of protection is high, is applicable to all aluminum-housed resistors.
