Embodiment
Example one
Fig. 4 is that band of the present utility model detects and the decomposition diagram of the attaching plug of control signal wire, band of the present utility model shown in Figure 4 detect and the attaching plug of control signal wire by earth connection inserted sheet 1, fixedly needle guard 2, holding wire probe assembly 2-0,2-0, live wire inserted sheet 4, zero line inserted sheet 5, ambroin system plug body 6, signal control line 7 and electric wire 8 constitute.One end of said fixing needle guard 2 and control signal wire firmly are connected by methods such as welding or punching presses, and above-mentioned earth connection inserted sheet 1, fixedly needle guard 2, live wire inserted sheet 4, zero line inserted sheet 5, ambroin system plug body 6, signal control line 7 and electric wire 8 formation are as a whole.When needs connect external connection electrical apparatus Equipment Inspection and control signal, above-mentioned holding wire probe assembly 2-0 is inserted in the fixedly needle guard 2 in the above-mentioned ambroin system plug body 6, be electrically connected by corresponding external connection electrical apparatus working state signal input terminal on probe shaft 2-2 among this holding wire probe assembly 2-0 and the socket.
