Abstract

The invention relates to a low-frequency standard signal switching device. The device comprises a junction box, a zero insertion force (ZIF) socket, a first socket, a second socket and a fuse socket, wherein the ZIF socket is connected with an adaptor; the ZIF socket is provided with an indented handle; and the first socket, the second socket and the fuse socket are positioned on the back panel of the junction box. Compared with the prior art, the low-frequency standard signal switching device has the advantages of low insertion plug, safety, reliability and the like.

Description

technical field [0001] The invention relates to a signal switching device, in particular to a low-frequency standard signal switching device. Background technique [0002] At present, the standard signal switching devices used in the field of aviation automatic testing at home and abroad mainly include VPC90 and ARINC 608A interface forms. The disadvantages of these two signal switching devices are mainly expensive, large in size, and large in insertion force. Contents of the invention [0003] The object of the present invention is to provide a safe and reliable low-frequency standard signal switching device with small insertion and withdrawal force in order to overcome the above-mentioned defects in the prior art. [0004] The purpose of the present invention can be achieved through the following technical solutions: [0005] A low-frequency standard signal switching device is characterized in that the device includes a junction box, a ZIF non-plugging force socket, a f...
