Summary of the invention
The utility model is the response speed improving sensor, shortens the response time of sensor, improves sensor stability and reliability, special proposition vehicle exhaust pyrostat.
The technical solution of the utility model is for this reason, vehicle exhaust pyrostat, comprise housing, one end of housing is closed, the other end is provided with fire-resisting cable and stretches out, and forms closed inner chamber, it is characterized in that: closed inner chamber is divided into again high temperature conducting region and insulation layer in housing, wherein be provided with detector unit in high temperature conducting region, detector unit wire exports fire-resisting cable to by insulation layer and exports; Surrounding's uniform filling of detector unit has aluminium nitride or boron nitride powder; Insulation layer is filled with magnesium oxide or alumina powder.
Further improvement is: described housing is divided into three gradual change type steps by fire-resisting cable external part to blind end, wherein first step location fire-resisting cable, and second step is insulation layer, and the 3rd part of step is high temperature conducting region, insulation layer and
Insulation layer and the high temperature conducting region of high temperature conducting region and closed inner chamber are corresponding.
Beneficial effect:
Closed inner chamber is divided into again high temperature conducting region and insulation layer to be conducive to the collection of temperature by the utility model; can the temperature authenticity that collects of actual response; also protect detector unit in the environment of a sealing simultaneously; be conducive to keeping its precision and increasing the service life, insulation layer needs the authenticity ensureing data transmission.
Detector unit peripheral part area filling aluminium nitride or boron nitride, aluminium nitride or boron nitride belong to super-high heat-conductive insulating material, have super-high heat-conductive performance, low-expansion coefficient, and heat conductivility is the several times of magnesium oxide or aluminium oxide.
The excellent magnesium oxide of high-insulativity or alumina powder are filled in insulation layer, and the feature that the ultra-high conducting of aluminium nitride or boron nitride can not only be utilized so hot shortens the response time of sensor, also can improve the reliability of sensor.
Three gradual change type steps be provided with the assembling and location that are beneficial to external structure, be simultaneously also conducive to the utilization to greatest extent of material and do not waste, having saved overall manufacturing cost.
Accompanying drawing explanation

Fig. 2 is that the G-G of Fig. 1 is to cut-open view.
In Fig. 1,1 is shell, and 2 is aluminium nitride or boron nitride powder, and 3 is detector units, and 4 is wires, 5 is magnesium oxide or alumina powder, and 6 is fire-resisting cables, and A is high temperature conducting region, and B is insulation layer, a face is the flat facial planes of housing, and b face is detector unit plane, and c face is first step location.
Embodiment
The utility model as Fig. 1,2, shown in.
Vehicle exhaust pyrostat, comprise housing 1, one end of housing 1 is closed, the other end is provided with fire-resisting cable 6 and stretches out, the inner chamber closed is formed in housing 1, the inner chamber closed is divided into again high temperature conducting region A and insulation layer B, and be wherein provided with detector unit 3 in the A of high temperature conducting region, detector unit 3 wire 4 exports fire-resisting cable 6 to by insulation layer B; Surrounding's uniform filling of detector unit 3 has aluminium nitride or boron nitride powder 2; Insulation layer B is filled with magnesium oxide or alumina powder 5.
Housing 1 is divided into three gradual change type steps by fire-resisting cable 6 external part to blind end, and wherein first step location fire-resisting cable, 6, second step is insulation layer B, and the 3rd part of step is high temperature conducting region A.
Insulation layer B and the high temperature conducting region A of insulation layer B and high temperature conducting region A and closed inner chamber are corresponding.
