The invention discloses an over-temperature and over-current protection device in an electronic instrument inspection process. The device includes a temperature control unit, a power socket unit, a relay unit and a power supply unit. The temperature control unit includes a temperature sensor, a temperature control processor and a liquid crystal touch screen. The temperature control processor is connected with the temperature sensor through a temperature sensing line. The liquid crystal touch screen is connected with the temperature control processor. The temperature sensor is adhered to the surface of the power socket unit. The temperature control processor is connected with the relay unit and the power supply unit. The relay unit is connected with the power socket unit. According to the invention, when over-temperature or over-current of a sample or an experiment cabin occurs, the device can cut off power supply immediately, so that the sample as well as the experiment cabin can be protected, and the personal safety of experimenters can be protected. The device can be used as an independent protection instrument.
Description
technical field [0001] The invention relates to the field of over-temperature and over-current protection of electronic instruments, in particular to an over-temperature and over-current protection device in the inspection process of electronic instruments. Background technique [0002] In the reliability testing process of electronic and electrical products, failures often occur. Some failures are caused by the failure of the sample itself, and sometimes it is caused by the failure of the testing instrument. No matter what causes the failure of the sample, it may cause some accidents or even serious accidents. For example, fire caused by short circuit, electric injury to staff and so on. [0003] The purpose of designing this product is to take actions such as power-off in time when the sample is short-circuited, so as to protect the instrument from damage and avoid fire and casualties. [0004] There is no similar product on the market now, and there are similar devices ...
