This utility model uses following technological means to realize utility model purpose.
A kind of gum cover of heatproof insulation protection; it includes insulation sleeve, metal tube, heater element, high-temperature insulation filler and metal mounting plate; described insulation sleeve is fixedly connected with metal mounting plate; insulation sleeve entangles described metal tube, and the built-in described heater element of metal tube also fills described high-temperature insulation filler.
Further, described insulation sleeve is the cylinder of central aperture.
Further, a recessed circle is offered in the centre position of the cylinder wall of described insulation sleeve, and recessed circle is fixed on metal mounting plate.
Further, the central aperture aperture of described insulation sleeve is equal to the lower deviation value of the tolerance of metal tube diameter, and insulation sleeve is used for fixing heater element, and heater element is tubular type.
Further, the outer pipe wall of described metal tube is arranged with a floor height heat conductive insulating glassy layer.
Further, the outer pipe wall of described metal tube is arranged with one layer of ceramic layer.
This utility model has the beneficial effect that the gum cover of a kind of heatproof insulation protection described in the utility model; it uses special silica gel; solidfied material has higher elasticity, insulated enclosure, can be the most high temperature resistant 250 degree, higher than the operating temperature of major part power test element seating portion.Insulation sleeve serves as the double insulation effect of the electrical insulator that electric conductor can contact with human body wherein, and its structure is to utilize the higher elasticity of insulation sleeve, high temperature and insulating properties.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
This utility model provides the gum cover of a kind of heatproof insulation protection, is described in detail this utility model below in conjunction with the accompanying drawings.
As shown in Figure 1; the gum cover of a kind of heatproof insulation protection described in the utility model; it includes insulation sleeve 1, metal tube 2, heater element 3, high-temperature insulation filler 4 and metal mounting plate 5; described insulation sleeve 1 is fixedly connected with metal mounting plate 5; insulation sleeve 1 entangles described metal tube 2, and the built-in described heater element 3 of metal tube 2 also fills described high-temperature insulation filler 4.Described insulation sleeve 1 is the cylinder of central aperture, and cylinder is easily installed.A recessed circle is offered in the centre position of the cylinder wall of described insulation sleeve 1, and recessed circle is fixed on metal mounting plate 5, it is simple to be fixedly installed in by insulation sleeve 1 in power class charged metal casing.The central aperture aperture of described insulation sleeve 1 equal to the lower deviation value of tolerance of metal tube 2 diameter, can close installation, insulation sleeve 1 is used for fixing heater element 3, and heater element 3 is in tubular type.Further, the outer pipe wall of described metal tube 2 is arranged with a floor height heat conductive insulating glassy layer, the outer pipe wall of the fully wrapped around metal tube of high heat conductive insulating glassy layer 2, not only good heat conductivity, insulating properties also can be greatly improved, another is preferred, the outer pipe wall of described metal tube 2 is arranged with one layer of ceramic layer, same, the outer pipe wall of the fully wrapped around metal tube of ceramic layer 2, not only good heat conductivity, also can be greatly improved insulating properties.Described high heat conductive insulating glassy layer or ceramic layer offer some inclined via-holes, have both been favorably improved radiating effect, and have contributed to again insulation.
Described insulation sleeve 1 is made up of the component that content is following percetage by weight: methyl vinyl silicone rubber (elastomeric compound main component) Organic polymer silioxne gum, its molecular formula is: ViMe2SiO(Me2SiO)n(MeViSiO)mSiMe2Vi, its composition accounts for 50-65%, and its preferred ratio is 62% and 63%；White carbon Silica, its molecular formula is: SiO2, its composition accounts for 20-25%, and its preferred ratio is 22% and 24%, silicone oil Hydroyl silioxne, and its molecular formula is: HO (Me2SiO) nH, its composition accounts for: 5-8%, and its preferred ratio is 6%, 7%；High temperature resistant auxiliary agent, its composition accounts for: 5-12%, and its preferred ratio is 6%, 8%, 10%.Preferably, described high temperature resistant auxiliary agent can be 245 to compound DLTP, YM74080 or 1076 and compound the type products such as DLTP.
In sum, the gum cover of a kind of heatproof insulation protection described in the utility model, it uses special silica gel, and solidfied material has higher elasticity, insulated enclosure, can be the most high temperature resistant 250 degree, higher than the operating temperature of major part power test element seating portion.Insulation sleeve 1 serves as the double insulation effect of the electrical insulator that electric conductor can contact with human body wherein, and its structure is to utilize the higher elasticity of insulation sleeve 1, high temperature and insulating properties.
The above is only better embodiment of the present utility model, therefore all equivalence changes done according to structure, feature and the principle described in this utility model patent claim or modification, all it is included in this utility model patent claim.
