Embodiment
See also shown in Figure 1, a kind of discharging rod 1 of acousto-optic indication, this discharging rod 1 comprises that an electroacoustic transducer 11, is connected in the loud speaker 12 of this electroacoustic transducer 11, a current-limiting resistance 13, one first light-emitting diode 14, one second light-emitting diode 15 and a change over switch 16; Described change over switch 16 comprises the conducting strip 164 that a first node 161, a Section Point 162, one the 3rd node 163 and the one and the 3rd node 163 articulate; Described conducting strip 164 selectively is connected with first node 161 or Section Point 162; The two is electrically connected described electroacoustic transducer 11 respectively at described current-limiting resistance 13, first node 161; Described current-limiting resistance 13 is electrically connected with the positive pole of described the first light-emitting diode 14, the negative pole of the second light-emitting diode 15 respectively; The anodal of the negative pole of described the first light-emitting diode 14, the second light-emitting diode 15 all is electrically connected with described Section Point 162; Described the 3rd node 163 is connected to ground connection.Testing crew is by described discharging rod 1, can touch test product to be measured 2 front confirm first should be to be measured test product 2 whether with electric charge, see through simultaneously the warning of sound and light signal, effective protection test personnel's safety.
Shown in Fig. 2-4, the utility model is when using, first described change over switch 16 is switched to the state that described the 3rd node 163 and Section Point 161 are electrically connected, the plus or minus utmost point and described electroacoustic transducer 11 with test product 2 to be measured is electrically connected again, and the other end electrode of test product 2 to be measured is connected ground connection; (see figure 2) when the positive pole of test product 2 to be measured and described electroacoustic transducer 11 are electrically connected, the described loud speaker 12 of the current trigger on the test product 2 to be measured, and light 14 pairs of ground connection discharges of described the first light-emitting diode; (see figure 3) when the negative pole of test product 2 to be measured and described electroacoustic transducer 11 are electrically connected, the described loud speaker 12 of the current trigger on the test product 2 to be measured, and light 15 pairs of ground connection discharges of described the second light-emitting diode; When described loud speaker 12 sound gradually little, and during the light diminuendo of described the first light-emitting diode 14 or the second light-emitting diode 15, described change over switch 16 can be switched to the state (see figure 4) that described the 3rd node 163 and first node electrical 161 join, to accelerate the velocity of discharge; When described loud speaker 12 does not have sound, and described the first light-emitting diode 14 and the second light-emitting diode 15 all do not have namely to represent discharge off of described test product to be measured 2 when shinny.
Although more than described embodiment of the present utility model; but being familiar with those skilled in the art is to be understood that; our described specific embodiment is illustrative; rather than for the restriction to scope of the present utility model; those of ordinary skill in the art are in modification and the variation of the equivalence of doing according to spirit of the present utility model, all should be encompassed in the scope that claim of the present utility model protects.
