12V and 24V fast switching direct-current composite battery box for testing

Abstract

The invention discloses a 12V and 24V fast switching direct-current composite battery box for testing. The battery box comprises a transparent box body, lighting mechanisms, a voltmeter, a second switch and a second connecting hole. A voltmeter is arranged on one side of the transparent box body, a second switch is arranged on one side of the voltmeter, a second connecting hole is formed in one side of the second switch, a first switch is arranged on the other side of the voltmeter, a first connecting hole is formed in one side of the first switch, and a mechanical switch is arranged on one side of the transparent box body; an installation mechanism is arranged at the top end of the transparent box body, a groove is formed in the bottom end of the cover body, a clamping groove is formed inone side of the groove, through holes are formed in the groove at equal intervals, the through holes are evenly distributed in the surface of the transparent box body, lighting mechanisms are arranged on the two sides in the transparent box body, and short circuit prevention mechanisms are arranged below the lighting mechanisms. The 12V and 24V quick switching direct-current composite battery boxfor testing can prevent short circuit, has a lighting effect and is convenient to install.

Description

technical field [0001] The invention relates to the technical field of inspection and detection, in particular to a 12V and 24V fast switching DC composite battery box for testing. Background technique [0002] In the electromagnetic compatibility (EMC) test of automotive electronic products, it is required that no additional electromagnetic energy should be introduced to the power supply equipment of the sample under test (EUT), and the frequent switching of the 12V / 24V voltage of the EUT power supply is usually done in the prior art. Make two battery boxes, namely a 12V DC battery box and a 24V DC battery box, first do the 12V test and then do the 24V test, which makes the operation inconvenient, and it wastes time to switch the battery box during the test, resulting in low test efficiency. . [0003] In the process of realizing the present invention, the inventors have found that at least the following problems in the prior art have not been resolved: [0004] (1) The t...
