Physical laboratory signal test experimental box

Abstract

The invention discloses a physical laboratory signal test experimental box, which comprises a box body and a cover body. The upper part of the box body comprises two parts, wherein the part close to the inner side has a rectangular groove in which a plurality of signal indicator lights are arranged; and the part close to the outer side has a plurality of control buttons on its surface each of which corresponds to a signal indicator light. A front surface of the box body is provided with signal line interfaces. A test circuit and a power source are disposed inside the box body. The test circuit is connected with the power source and the signal line interfaces, connects a signal line to the corresponding signal line interface, and tests the signal line by turning on the control button. The physical laboratory signal test experimental box is simple in structure and convenient to operate. Just by inserting the two ends of the signal line into the signal input ports of the physical laboratory signal test experimental box, turning on the switch, and observing the indicator light, the on / off state, the connection state, the type and the like of the signal line can be determined, thereby saving time, avoiding a waste to time caused by taking the wrong signal line, and improving the work efficiency of an operator.

Description

technical field [0001] The invention discloses a signal test experiment box, in particular to a signal test device in a physics laboratory, which belongs to the field of teaching appliance applications. Background technique [0002] At present, in the classroom of physics experiment teaching, the following problems generally exist: [0003] 1. The media experiment means that students "watch experiments" through the media. Some experiments that students can do by themselves are displayed in multimedia, which is called "the application of modern technology". [0004] 2. Although the students do it by hand, they mainly use simple mechanical operations. According to the experimental purpose, equipment, and steps explained by the teacher, the students operate according to the prescribed steps like doing radio exercises to obtain what the teacher (or books) requires. The experimental data (or experimental results) without considering why the experiment is done, how to do it, let ...
