Abstract

The present invention discloses a circuit protection device, which is connected with testing equipment and a device to be tested. The circuit protection device includes: a first interface, electrically connected to the device to be tested, to obtain a first level state; a protection circuit, which one end is electrically connected to the first interface, obtains the first level state, and controls the on-off of the protection circuit according to the first level state; the second interface, one end of which is connected to the other end of the protection circuit electrically connected, and the other end is electrically connected with the test equipment. With the circuit protection device of the present invention, since the first level state of the equipment under test is obtained through the first interface, the on-off of the protection circuit is controlled according to the first level state, so that the testing equipment can be controlled. Protect.

Description

【Technical field】 [0001] The invention relates to a circuit protection device, in particular to a circuit protection device for testing equipment. 【Background technique】 [0002] With the development and progress of science and technology, electronic products are more and more widely used in home and office occasions, especially personal desktop computers and notebook computers, which have become an indispensable tool in people's life. [0003] Therefore, mass production of such electronic products is required. Before the factory needs to ship, its performance needs to be tested to ensure its quality. [0004] see figure 1 , which is shown as a test structure diagram of an electronic product in the prior art. In current tests, the testing device 100 is usually electrically connected to the device under test 200 directly. [0005] The device under test 200 is an example of a notebook computer display, and the testing device 100 is an example of a notebook computer host. ...
