Piece type piezo-resistance.
Background technology
Traditional piezo-resistance, all it is mainly the piezo-resistance of plug-in unit mode, and it is rare pressure-sensitive with remote signaling function
Resistance, is all a pin using main temperature fuse, external circuitses, to monitor whether piezo-resistance fails.This pattern
It is very risky, impact is possible to when being struck by lightning and arriving on observation circuit, because detection circuit is very fragile, it is easy to be struck by lightning
Break.After observation circuit failure, the quality of piezo-resistance can not be correctly indicated, piezo-resistance, which may explode, burn, etc. endangers
It dangerous situation condition, can not just monitor, be extremely hazardous.
Utility model content
The technical problems to be solved in the utility model is：A kind of patch-type piezo-resistance of band protection is provided, not only product
Small volume, simple in construction, paster installation, suitable for automation, large-scale production, and carry single remote signaling function, safer
Reliably.
Technical scheme is used by the utility model solves its technical problem：A kind of pressure-sensitive electricity of patch-type of band protection
Resistance, including piezo-resistance body, described piezo-resistance body tow sides are printed on conductive electrode, front side conductive electrode and first
Metallic conductor one end connects, and the first metallic conductor other end welds with fuse；Described fuse and second metallic conductor one end are welded
Connect, the second metallic conductor other end extends outside insulation heatproof encapsulating housing, and carries out being bent to form first electrode；Described
Piezo-resistance body reverse side conductive electrode is connected with the 3rd metallic conductor one end, and the other end of the 3rd metallic conductor extends insulation
Outside heatproof encapsulating housing, and carry out being bent to form second electrode；Thermal Cutoffs is close proximity to piezo-resistance body, and with the 4th
The other end of one end of metallic conductor and one end connection of fifth metal conductor, the 4th metallic conductor and fifth metal conductor
Extend outside insulation heatproof encapsulating housing, and carry out being bent to form the 3rd electrode and the 4th electrode respectively.
Further, when piezo-resistance body temperature described in the utility model raises extremely, heat passes through the first gold medal
Category conductor is delivered to fuse and the fuse that fuses.
Further say, Thermal Cutoffs described in the utility model switchs for remote signaling function；When piezo-resistance body
When temperature anomaly raises, Thermal Cutoffs provides a switching signal to remote port.
Further say, piezo-resistance body described in the utility model is single piezo-resistance or multiple pressure-sensitive electricity
The connection in series-parallel combination of resistance.
Further say, insulation heatproof encapsulating housing described in the utility model is plastic casing or ceramic shell.
The beneficial effects of the utility model are that solve defect present in background technology, not only come with remote signaling function,
The remote signalling is single, insulation a Thermal Cutoffs, more securely and reliably；And it is designed as the packaged type of paster, body
Product is compact, is more favorable for using and installing for user.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is structural representation of the present utility model；
In figure：10. piezo-resistance body；20. Thermal Cutoffs；31st, 32,33,34,35. be all metallic conductor；It is 40. exhausted
Edge heatproof encapsulates housing；50. fuse.
Embodiment
The utility model is described in further detail presently in connection with accompanying drawing and preferred embodiment.These accompanying drawings are letter
The schematic diagram of change, only illustrates basic structure of the present utility model in a schematic way, thus its only show it is relevant with the utility model
Composition.
It is as shown in Figure 1 as shown in figure 1, a kind of patch-type piezo-resistance of band protection, including piezo-resistance body 10, pressure
The quick tow sides of resistor main body 10 are printed on conductive electrode, and front side conductive electrode is connected with the one end of metallic conductor 34, metallic conductor 34
The other end welds with fuse 50, and fuse 50 welds with the one end of metallic conductor 35, and the other end of metallic conductor 35 extends insulation heatproof
Encapsulate outside housing 40, and carry out being bent to form first electrode, when piezo-resistance body 10 is by various types of overvoltage, lead
When causing body temperature exception rise, heat is communicated to fuse 50 by metallic conductor 34, so that fuse 50 effectively disconnects；It is pressure-sensitive
The reverse side conductive electrode of resistor main body 10 is connected with the one end of metallic conductor 33, and the other end of metallic conductor 33 extends insulation heatproof encapsulating
Outside housing 40, and carry out being bent to form second electrode；Thermal Cutoffs 20 is close proximity to piezo-resistance body 10, and is led with metal
Body 31 connects with 32 one end, and the other end of metallic conductor 31 and 32 extends outside insulation heatproof encapsulating housing 40, and is bent
Form the third and fourth electrode.
When piezo-resistance body 10 is by various types of overvoltage, when causing body temperature exception rise, heat passes through
Metallic conductor 34 is communicated to fuse 50, so that fuse 50 effectively disconnects.
Thermal Cutoffs 20 is used as remote signaling function, when piezo-resistance body 10 is by various types of overvoltage, is led
When causing body temperature exception rise, remote signalling experiences the temperature of body so as to disconnect, and gives remote port to provide a switching signal.
