Detailed Description
In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention is described in detail with reference to the accompanying drawings and the detailed description.
As shown in fig. 1 to 3, a fast-plugging microammeter with controllable on-off comprises a high-voltage microammeter 3 and a connecting piece matched with the high-voltage microammeter. The connecting piece comprises a four-pin plug 2, a banana plug 4 and a high-voltage leading-out wiring terminal 5. Four-pin plug 2 is installed at 3 tops of high-pressure microampere table, installs banana plug 4 under 3 of high-pressure microampere table, installs on high-pressure leading-out terminal 5 when banana plug 4 uses, and high-pressure leading-out terminal 5 then installs directly over pressure doubling cylinder 6.
The high-voltage microammeter 3 is internally provided with a precise circuit board with the model number of 2C00011A and is provided with a backlight four-digit digital display screen. The four-pin plug 2 is a 17mm square base and is firmly fixed right above the high-voltage microampere meter 3 through four screws. The tail end plug of the high-voltage output line 1 is accurately and well connected with the four-pin plug 2 in a self-locking mode, and an error-preventing notch is formed in the four-pin plug 2 to prevent the four-pin from being inserted wrongly. When the inner connectors of the plug at the tail end of the high-voltage output line 1 are short-circuited and inserted into the four-pin plug 2, the controllable function of the switch of the microammeter can be realized, as shown in fig. 4.
