Abstract
The utility model relates to a magnetic switch. One terminal of a magnetic temperature switch 1 is connected with a silver plated electrode in one side of a thermistor 2 and an earth wire 5, the other terminal of the magnetic temperature switch 1 is connected with an alarm terminal 6, and a silver plated electrode in the other side of the thermistor 2 is connected with a sensor terminal 7. The connecting components are totally arranged in a casing. The utility model has the advantages that tne magnetic switch can switch and alarm to a specific temperature, and also can sense and detect the entire temperature changing procedure of the object under detection, namely the magnetic switch can make the temperature changing have a signal output of analog quantity through the thermistor, and so the magnetic switch has the function of linear output of the temperature signal. The utility model has simple structure, reliable and stable performance, small volume and convenience in installation and use and compared with like products the magnetic switch has low manufacturing cost.
Description
Technical field
The utility model relates to automobile temperature alarming attachment technique field, specifically a kind of magnetic switch.
Background technology
Magnetic-sensing temperature switch has been applied in the engine of automobile as a kind of sensor alarm of specified temp at present, certain temperature spot to engine coolant carries out sensor alarming, and this element is compared with the temperature sensor of other similar functions has characteristics simple in structure, dependable performance.Magnetic-sensing temperature switch is made of soft, Hard Magnetic ring and tongue tube, and this element is this character of sudden change of utilizing near soft magnetic material magnetic characteristic Curie temperature, makes the reed adhesive in the tongue tube and disconnects and realize a certain specified temp is carried out sensor alarming.In other words, this element only can sensing and a certain specified temp of reflection measured object, and can't sensing and a certain segment limit of reflection in the process and the value of temperature variation, its usability is comparatively single.
Summary of the invention
To be that design is a kind of can not only carry out switch to a certain specified temp and report to the police the purpose of this utility model, but also have the magnetic switch that temperature variation is carried out the function of in good time sensing.
The utility model magnetic switch comprises: the silver-plated electrode of a side of magnetic temperature switch one end and thermistor, ground wire link to each other, the other end of magnetic temperature switch links to each other with the end of reporting to the police, the silver-plated electrode of the opposite side of thermistor links to each other with sensor ends, and above-mentioned continuous parts are all cased.Also have remaining part all cased in addition.Thermistor is contained in outside the shell.
Shell comprises the plastic cover plate at brass tube and brass tube two ends.
Magnetic temperature switch is connected to form by tongue tube and magnet ring.
The advantage of the utility model magnetic switch is: both can carry out switch to the temperature of a certain setting and report to the police, can carry out sensing and detection to the whole temperature changing process of measured object again, promptly can make its temperature variation that the signal output of an analog quantity be arranged by thermistor.Had the function of the linear output of temperature signal, the utility model product is not only simple in structure, and dependable performance is stable, and volume is little, and is easy to install, and compared with similar products, its cost of manufacture is also comparatively cheap.
