Realize above-mentioned purpose technical scheme: the temperature sensor of high response accuracy, it is characterized in that: the housing that comprises an end opening, in the port of shell nozzle end, be provided with the first epoxy sealing, the openend of housing is provided with the static contact and the conductive plate that are upper and lower horizontal arrangement, one end of static contact and conductive plate extends in housing through first ring epoxy resins, the protruding first ring epoxy resins of the other end of static contact and conductive plate, one end that static contact extends in housing is provided with fixed contact, in one end away from openend in housing, be provided with bearing, on bearing, be supported with bimetal leaf, the arcwall face of bimetal leaf is supported on housing bottom, bimetal leaf top is provided with the spring leaf of horizontal arrangement, one end of spring leaf is supported on described bearing, the other end of spring leaf is provided with moving contact, described moving contact and fixed contact can contact settings, between bimetal leaf and spring leaf, be provided with inverted T-shaped guide pin bushing, inverted T-shaped guide pin bushing is supported on described bearing, the vertical section of inverted T-shaped guide pin bushing is provided with vertical through hole, in the vertical through hole of inverted T-shaped guide pin bushing, place fore-set, the lower end of fore-set is supported on the center of bimetal leaf, expand with heat and contract with cold and drive fore-set to slide up and down along inverted T-shaped guide pin bushing by bimetal leaf, thereby drive the moving contact of spring leaf end and the adhesive of the fixed contact of static contact end and separate, one end of described bimetal leaf is electrically connected with spring leaf, and the other end of described bimetal leaf is electrically connected with conductive plate.
One end of the protruding first ring epoxy resins of static contact and conductive plate is connected with respectively wire, and one end that static contact, conductive plate are connected with wire is by the second epoxy resins insulation sealing.
The utility model transmits by push rod the mutability that bimetallic is produced by variations in temperature, promotes the disjunction of spring leaf band moving contact, realizes temperature control and thermal overload protection.
The beneficial effects of the utility model:
1, the utility model drives separation and the adhesive between dynamic and static contact by fore-set, and the length of fore-set can freely be matched, eliminate the error that product may occur in manufacture process, improved the product precision of output and the long-time stability of performance in batches.
2, between bimetal leaf and dynamic and static contact in two spaces independently, avoided the long-term disjunction in contact to produce the impact of electric arc on bimetal leaf, there is higher temperature sensitiveness, repeatability and reliability.
3, bimetal leaf and housing are close to the temperature following that can improve product.
