Description
Technical field
The present invention relates to thermistor field, specially a kind of thermistor voltage-withstand test method.
Background technology
Thermal resistor is one kind of sensing element, is divided into positive temperature coefficient thermistor according to temperature coefficient difference
(PTC) and negative temperature coefficient thermistor (NTC).The typical feature of thermal resistor is temperature sensitive, different temperature
Under show different resistance values.Positive temperature coefficient thermistor (PTC) resistance value when temperature is higher is bigger, negative temperature system
Number thermal resistor (NTC) resistance value when temperature is higher is lower, they belong to semiconductor devices.In PTC thermistor
In production, the zero power resistance to PTC thermistor, actuation time, the time of being failure to actuate, pressure resistance and service life, resistance to power frequency is needed to rush
It the projects such as hits to be tested and tested, the past one is to being progress simple function test on different devices.
As shown in Figure 1, when carrying out voltage-withstand test to thermistor product, after needing 3 short circuit of lead by test product 1
As an electrode, temperature measuring head outer wrapping copper foil 2 is used as another electrode, two electrodes respectively with two electricity of pressure tester
Press output terminal electrode connection.When the dielectric strength of product is less than design requirement, pressure tester sends out alarm signal, prompts product
Dielectric strength is unqualified.This test method efficiency is low, and there are copper foil and temperature measuring head package it is not close, measurement data is not allowed
True hidden danger.
Invention content
The purpose of the present invention is to provide a kind of thermistor voltage-withstand test methods, solve test in the prior art
Method efficiency is low, copper foil and temperature measuring head wrap up the problems such as not close and measurement data is inaccurate.
The technical scheme is that：
A kind of thermistor voltage-withstand test method first, steel ball is put into two insulating vessels, the two of pressure tester
A voltage output termination electrode is respectively put into two insulating vessels fixed；Then, by the lead of thermistor test product whole
It is put into an insulating vessel equipped with steel ball, makes in lead embedment steel ball；The temperature measuring head of thermistor test product is put into
In another insulating vessel equipped with steel ball, make in temperature measuring head embedment steel ball；Finally, pressure tester test switch is opened, into
Row voltage-withstand test.
The thermistor voltage-withstand test method, when carrying out product voltage-withstand test, while to two sets or more temperature-sensitive electricity
It hinders test product and carries out voltage-withstand test.
The voltage-withstand test method is incited somebody to action, diameter of the steel ball 1-10mm.
Advantages of the present invention and advantageous effect are：
Using the present invention when carrying out product voltage-withstand test, the lead of more set products can be all put into equipped with steel ball
In container, temperature measuring head is put into another container equipped with steel ball.Open pressure tester test switch, while to covering product more
Voltage-withstand test is carried out, improves work efficiency and avoid the hidden danger of measurement data inaccuracy.
Description of the drawings
Fig. 1 is the test method schematic diagram before improving.In figure, 1 test product；2 copper foils；3 leads.
Fig. 2 is improved test method schematic diagram.In figure, 1 test product；3 leads；4 steel balls；5 insulating vessels.
Specific embodiment
As shown in Fig. 2, the improved test method of the present invention is as follows：
The steel ball 4 of a diameter of 2mm is respectively put into two insulating vessels 5, two voltage output ends of pressure tester
Electrode is respectively put into two insulating vessels 5 fixed (not further taking out, used after convenient).When carrying out product voltage-withstand test,
The lead 3 of 10 sets of thermistor test products 1 is all put into an insulating vessel 5 equipped with steel ball 4, thermistor is tested
The temperature measuring head of product 1 is put into another insulating vessel 5 equipped with steel ball 4.Open pressure tester test switch, you can carry out
Voltage-withstand test.The method increase working efficiency, and avoid the hidden danger of measurement data inaccuracy.
