Further, the resistance is 120Ω, and the capacitance is 0.1 μF.

Further, the aviation plug adopts a GX16 type aviation plug.

The beneficial effects produced by adopting the above-mentioned technical scheme are:

In the present invention, the terminal circuit is welded into the pluggable aviation plug female head, and the COMMS OUT end on the acquisition board is led out of the acquisition board shell through the aviation plug male head, as long as the aviation plug female head with the terminal circuit is connected to the On the male connector of the aviation plug, the collection board where the male plug of the aviation plug is located can be used as the last collection board. It can be installed without opening the acquisition board shell every time it is plugged and unplugged, and the operation is easy.

The invention has the characteristics of simple structure, convenient processing and portability. The invention is suitable for the occasion of going out for mobile operations, and only needs to carry the aviation plug female head, which improves the test work efficiency and instrument use efficiency, and reduces the labor intensity on site.

The aviation plug female head is filled with epoxy resin as a filler, which has excellent bonding strength, good dielectric properties, and small shrinkage rate, so that the aviation plug female head has good dimensional stability and high hardness.

detailed description

In order to make the purpose, technical solution and advantages of the present invention clearer, the invention will be clearly and completely described below in conjunction with the accompanying drawings and specific embodiments.

As shown in accompanying drawing 1 and 2, be used for the plug-and-play type terminal device of test data acquisition system, comprise acquisition board 1, the acquisition board housing 2 that is enclosed within acquisition board 1, COMMS on the described acquisition board 1 The OUT end 3 is connected to the aviation plug male head 4-1 outside the acquisition board housing 2 through the wire 5, and the aviation plug male head 4-1 is provided with a detachable aviation plug female head 4-2 matched therewith, The aviation plug female 4-2 has a built-in terminal circuit, and the terminal circuit includes a resistor 6 and a capacitor 7. As shown in Figure 2, the resistor 6 and capacitor 7 are connected in series between the positive and negative terminals of the aviation plug female 4-2. Between the negative poles: epoxy resin is filled in the aviation plug female 4-2.

The aviation plug male 4-1 and the aviation plug female 4-2 adopt the GX16 type, the interface type: AC/DC, the shape: round, the number of cores: 2, the manufacturing process: cold pressing, and the insulator material: plastic master.
