Specific embodiment
It elaborates below in conjunction with the accompanying drawings to specific embodiment of the utility model.
As shown in Figure 1, a kind of pyrostat, includes housing 1, housing 22, cavity 1, cavity 24, conducting wire 5, peace
Fill seat 6, groove 9, partition plate 10 and PTC thermistor chip 11, the housing 1 and the housing 22 by the bolt and
Nut connects, and the cavity 1 of a closing is formed in housing 1, and the PTC thermistor chip 11 is arranged at cavity 1
Middle part, housing 22 is provided with the groove 9 at the position of housing 1, the sky of a closing formed in housing 22
Chamber 24, the partition plate 10 are connected with housing 22, and cavity 24 is separated into four B of three A of cavity and cavity by partition plate 10, partition plate 10
Both ends are machined with through hole, and for through conducting wire 5, being provided with a cross mounting base 6 in four B of cavity, mounting base 6 includes horizontal stroke
Bar and montant, the bottom of the montant are connected with housing 1, and the both ends of the cross bar are machined with through hole, the conducting wire 5 through
The inside of housing 1 and housing 22, conducting wire 5 have two, and one end of conducting wire 5 is connected with PTC thermistor chip 11, the other end
Through two through holes on 6 cross bar of mounting base to the outside of housing 22, filled with Heat Conduction Material in cavity 1, in three A of cavity
Filled with heat sink material.
As a preferred embodiment, protective case 8 is installed on the conducting wire 5 in four B of cavity.
Alternatively preferred embodiment is provided with sealing ring 7 between the conducting wire 5 and housing 22.
In order to increase the accuracy of testing result and detection efficiency, the housing 1 is metal shell.
In specific production process, conducting wire 5 is welded to connect with PTC thermistor chip 11, by PTC thermistor chip 11
The middle part of the cavity 1 of housing 1 is positioned over, then forms the oxide of Heat Conduction Material, that is, magnesium and alcohol by dispenser
Mixture is filling in the inside of cavity 1, is then positioned over housing 1 after being dried in drying equipment and seals filling gap
Firmly, on the one hand Heat Conduction Material plays the role of fixed PTC thermistor chip 11, the conduction of another aspect heat.By conducting wire 5
