Specific embodiment
Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example is served only for explaining this practicality
New, it is not intended to limit scope of the present utility model.
As Figure 1-3, a kind of carbon film bridge silk, including columned matrix 1, described matrix 1 be respectively arranged at two ends with use
In conductive metal cap 2, it is provided with one layer of carbon film 3 in the outside of described matrix 1, and described carbon film 3 is provided with an arcuate groove
4, on described carbon film 3 and the part between corresponding described arcuate groove 4 two ends form energising after generate heat the ignition point 5 ignited.Carbon film 4
Electric conductivity preferably so that energy is as few as possible consumes in carbon film 4, and then concentrate on ignition point 5.
The depth of described arcuate groove 4 is equal to or more than the thickness of described carbon film 3, transmits after metal cap 2 energising on carbon film 3
During so that electric energy only passes through from ignition point 5, reach the purpose concentrating on ignition point 5 of energy so that the ignition of carbon film 3
Carbon film maximized generation heat in point 5, is finally completed burning and ignites.
Preferred: the width of described arcuate groove 4 is 0.1-0.2mm, on the basis of existing process, completes minimum arcuate groove 4
Cutting width, the length of side of arcuate groove 4 ignition area is reduced with this so that energy concentrate.The spiral shell liter of described arcuate groove 4
Angle is 0-60 °, and above-mentioned spiral shell lift angle is so that the area of ignition point 5 is controlled, and can change ignition by the adjustment that spiral shell rises angle
The area of point 5, can adjust simultaneously and complete bridge silk resistance to adapt to different use requirements.
The manufacturing process of above-mentioned carbon film bridge silk, comprises the steps:
(1) the Ceramic manufacturing making matrix 1 of the pottery of selection 30% aluminium oxide or magnesium oxide:
The material of matrix 1 selects the pottery of capacity of heat transmission difference, so that 3 caloric values of carbon film will not be by ceramic matrix 1
Conduction, reaches heat concentration and cuts indiffusible purpose.Matrix 1 can be selected with any material following:
A. select the material for matrix 1 for the pottery of 30% aluminium oxide: heat conductivity can be greatly lowered, control heat conductivity
Below 8, the capacity of heat transmission of the ceramic matrix 1 of 30% aluminium oxide is the half of the ceramic matrix 1 of 95% aluminium oxide；
B. select the material that Talcum ceramic material (magnesia ceramics) is matrix 1: the quality proportioning of Talcum ceramic material is as follows: two
Silica content: 60%；Content of magnesia: 30%.Steatite ceramic ceramic phase is more crisp to other materials, should not be used in common electricity
Resistance, disposable handling characteristicss can be entirely acceptable for carbon film bridge silk.
(2) adopt normal heptane as the raw material that carbon film 3 is plated on matrix 1, and utilize 300-400 DEG C of height after plated film
The initial resistivity value to reduce carbon film 3 for the technique of temperature tempering:
By specific technique during plating carbon film 3 on matrix 1, improve carbon film 4 electric conductivity and carbon film 4 attachment matrix
1 ability, so that the initial resistivity value of plated carbon film 4 is tried one's best reducing, the adhesive ability of raising carbon film 4 simultaneously, reliability,
Concordance.Specific as follows:
A. adopt normal heptane as the raw material of plating carbon film 4, can be effective when normal heptane is used for plating carbon film 4 material
Reduce the generation of carbon three key, and then improve the conductive capability of carbon film 4 so that the resistivity of carbon film 4 lowers, reach carbon film 4 initial
The reduction of resistance value；
B. reduce the initial resistivity value of carbon film 4 using the technique of high tempering, pass through again after plated film 4 on matrix 1
Carbon three key within carbon film 4 can be effectively converted into carbon two key, thus improving carbon by 300-400 DEG C of high-temperature tempering process
The conductive capability of film 4.
When carbon film 4 is difficult to plated film on the matrix 1 that adheres to, add the jointing material of speciality on matrix 1 surface, such as using
When 30 aluminium oxidies and Talcum ceramic material are as matrix 1, can adopt because matrix 1 rough surface is difficult to plated film in coating process
It is applied in the attachment carrying out carbon film after ceramic matrix 1 again with special binding agent.
(3) using cutting, ring cutting technique is not processed into, to the carbon film 3 on matrix 1, the arcuate groove (4) do not closed, and formed send out
Fire point 5:
The purpose reaching required for arcuate groove 4 is processed on carbon film bridge silk: on the basis of cutting not ring cutting carbon film 4, to the greatest extent
The length of side of possible ignition point 5 area making arcuate groove 4 is minimum, reaches the localization effects of energy, finally makes in ignition point 5
Carbon film maximized generation heat.Specific as follows:
A. arcuate groove 4 not can exceed that 1 circle, and length must form ignition point 5 less than 360 °, must ensure carbon film 4
There is ignition point 5, the less heating effect of ignition point 5 area is more obvious；
B. the optimum range of the spiral shell lift angle of arcuate groove 4 is at 0-60 °, certain spiral shell lift angle so that heating area is controlled,
And carbon film ignition area can be changed by the adjustment that spiral shell rises angle, can adjust simultaneously and complete carbon film bridge silk resistance to adapt to difference
Use requirement；
C. arcuate groove 4 width control system, in 0.1-0.2mm, on the basis of existing process, completes minimum cutting width, is come with this
Reduce the length of side of cutting ignition area, so that energy is concentrated.
(4) initial resistivity value of carbon film bridge silk is optimized:
By the metallization of carbon film bridge silk carbon film 4 is improved with the electric conductivity of carbon film 4, selected metal is with respect to carbon
Material has more preferable conductive capability, so replace the part carbon film 4 of carbon film bridge silk using fraction metal material.To carbon film
The initial resistivity value of bridge silk is optimized method a following two kinds:
A., a small amount of metallic slurry (silver paste) is smeared on the carbon film 4 of carbon film bridge silk to reduce initial resistivity value, thus utilizing
It is attached on carbon film 4 the excellent electric conductivity of metal to improve the monolithic conductive performance of carbon film bridge silk；
B. the length lengthening carbon film bridge silk two ends metal cap 2 reduces the purpose of initial resistivity value, by lengthening carbon film
The metal cap 2 at bridge silk two ends so that metal material can replace the carbon film function of part, thus improving neatly leading of carbon film bridge silk
Electrical property.
(5) two ends in matrix are respectively mounted the manufacture that metal cap 2 can complete carbon film bridge silk.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all in this practicality
Within new spirit and principle, any modification, equivalent substitution and improvement made etc., should be included in guarantor of the present utility model
Within the scope of shield.
