Description

A lightning strike test box for electronic products

technical field

The utility model relates to a testing device for electronic products, in particular to a lightning strike test box for electronic products.

Background technique

Lightning strikes in nature (referring to indirect lightning, such as lightning strikes within or between clouds, or lightning strikes on nearby objects) can induce surge voltage and current on outdoor overhead lines. In addition, in power stations or switchyards, large surge voltages and currents will also be induced on power supply lines at the moment of switching of large switches. The common feature of these two kinds of surges is that the energy is extremely large (compared with energy, static electricity is at the picojoule level, pulse group is at the millijoule level, and lightning surge is at the hundreds of joule level, which is a million of the interference energy of the first two types. times), but the waveform is slow (microsecond level, while static electricity and pulse groups are nanosecond level, or even sub-nanosecond level), and the repetition rate is low. With the development of electronic technology, the reliability and safety requirements of electronic products are getting higher and higher, and the safety protection of electronic products, especially the protection of electronic products against lightning strikes or surges is becoming more and more critical. Therefore, in the development and production process of electronic products, the lightning strike test of electronic products becomes very important. In the prior art, the main problems of the lightning strike test device are: first, only one electronic product can be tested at a time, and the efficiency is low; Third, during the lightning test of electronic products, the testers cannot be informed of the explosion of the product in time.

Utility model content

The technical problem to be solved by the utility model is to provide a lightning strike test box for electronic products in view of the deficiencies in the prior art above. The lightning strike test box is simple in structure, easy to operate, and can test multiple electronic products at one time. With good performance, testers can be informed of lightning strike and explosion problems of electronic products in time.

In order to solve the above technical problems, the technical solution of the present invention is: a lightning strike test box for electronic products, including a box body, the box body is provided with at least two layers of lightning test compartments for placing electronic products, at least two alarm lights, at least two smoke sensors, an audible alarm and a control device; the number of lightning strike test compartments, warning lights and smoke sensors matches, and each lightning strike test compartment corresponds to a warning light and a Smoke sensor; the alarm lamp, smoke sensor and sound alarm are respectively electrically connected to the control device; when an electronic product in a certain lightning test room explodes in a lightning test, the smoke sensor The device transmits the smoke information to the control device, and the control device controls the sound alarm and the corresponding alarm light to alarm.

As a further elaboration of the utility model:

The box body also includes at least two lightning strike test power sockets, the number of lightning strike test power sockets matches the number of lightning strike test compartments, and each lightning strike test compartment corresponds to a lightning strike test power supply jack.

The box body is provided with five lightning strike test compartments, five warning lamps and five smoke sensors, and a cooling fan is installed on the side wall of each lightning strike test compartment.

The box body has a box door, and when the box door is closed, each lightning strike test compartment is a closed lightning strike test compartment. Further, the box door is a transparent box door, so as to observe the lightning strike test of electronic products.

The beneficial effects of the utility model are: the lightning strike test box is simple in structure, easy to operate, and can test multiple electronic products at one time, and has good protection performance when the lightning strike test explodes, allowing testers to learn about the lightning strike and explosion problems of electronic products in time.

First, because the box body has at least two layers of lightning strike test compartments for placing electronic products, the utility model can test multiple electronic products at one time, and the test efficiency is high; second, when the electronic products are damaged or In the event of an explosion, the box shell can play a protective role; third, because the number of lightning strike test compartments, alarm lights and smoke sensors matches, and each lightning strike test compartment corresponds to a warning light and a smoke sensor respectively, Therefore, when the electronic product in any lightning strike test compartment explodes in the lightning strike test, the corresponding smoke sensor in the lightning strike test compartment will transmit the smoke information to the control device, and the control device will control the sound alarm and the corresponding alarm light to alarm. Thereby, the lightning strike test personnel are informed of the lightning strike explosion problem of electronic products in time; Fourth, all the above components are assembled in a box body, which has a simple structure and is easy to operate.
