Description
Technical field
The utility model is related to circuit test field, more particularly to a kind of safety instrumentation.
Background technology
In modern society, mobile terminal is seen everywhere, such as mobile phone, panel computer and intelligent wristwatch etc., these movements
All using the lithium battery of Large Copacity as power supply, therefore performance to battery has reliability requirement very high to terminal.These movements
Terminal before product export, it is necessary to carry out some safety testings, for example, heavy-current discharge experiment or high temperature resistant experiment,
But in tens amperes of high current scale-up, especially directly by battery plus-negative plate short circuit (the big battery of capacity is straight
Electric current when connecing short circuit has hundreds of amperes) experiment in, battery be easy to produce blast or Ignition Phenomena.
At present when in the past carrying out battery short circuit and testing, first with wire by tested battery direct short-circuit, then tester
Member is tested by hand close to battery, needs to note battery status and testing time (when i.e. short-circuit constantly in test process
Between), this method obviously can allow the tester to have a pavid psychology, and the situation of battery explosion occurs in worry, or worries leakage liquid
Body is splashed on body or in eyes, so as to testing efficiency can be largely effected on, and life to test man also has larger safely
Potential injury.

Heater 17, the heater 17 and the control button panel 11 are additionally provided with inside the test box 1
Electrical connection.
The also test window 18 including salable closing of the test box 1, for placing product to be measured on the testboard 2
Product.
When carrying out short-circuit test, product to be measured is arranged on the testboard 2 by the test window 18 first, and
Connected with the short circuit current, it is that the product to be measured enters to control the short circuit current to connect by the key control panel 11
Enter short-circuit condition to be tested, if exploded after product short circuit, the gas for producing that explodes causes the pressure reductor 13
To elastic ball 14 described in external compression, so that alleviate the pressure that test box side wall is subject to, the gas that further blast is produced
Can be filtered out by being arranged at the gas-filtering device 3 outside test box 1, prevent the tested personnel of pernicious gas from sucking.
When carrying out high temperature test, product to be measured is arranged on the testboard 2 by the test window 18 first, so
Afterwards by the key control panel 11 control the heater 17 carry out heating setpoint to setting temperature, setting temperature
The stability of degree lower test product to be measured, even if product to be measured explodes because of high temperature, the test box 1 can play anti-
Shield is acted on.
Compared with prior art, product to be measured is placed on survey by safety instrumentation of the present utility model using test box
Tested in test stand, and test condition is set by setting with the control button panel outside test box, can be by institute
State control button panel to control product short circuit to be measured or carry out heating test to test product, even if test product generation is quick-fried
It is fried, it is also possible to which that the test box controls within casing explosive；In addition, being provided with pressure reductor in test box, it is also possible to carry
The explosion-proof performance of test box high；Furthermore, can also will explode what is produced by being arranged at the gas-filtering device outside test box
Toxic and harmful is filtered out, and prevents tested personnel from sucking, and protects the health of tester.
Above content is to combine specific preferred embodiment further detailed description of the utility model, it is impossible to
