Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
The miniature operating case of the utility model mutual inductor polarity test as shown in Figure 1 and Figure 2, comprise box body 5, power switch 1, button 2, power light 3, output indicator 4, binding post 6, test circuit is equipped with in box body 5 inside, binding post 6 is two, and two binding posts are respectively the sub-A1 of cathode output end and the sub-A2 of cathode output end.In described test circuit, power switch K1 controls the break-make of whole circuit, power light LED1 be connected into major loop after current-limiting resistance R1 connects, connect with button K2 after output indicator LED2 connects with current-limiting resistance R2 and then access major loop, the sub-A1 of cathode output end is connected into node between button K2 and current-limiting resistance R2, and the sub-A2 of cathode output end is connected with the negative pole of output indicator LED2.
The plastic casing that in the utility model, box body 5 can fasten for the up and down.Power switch 1 is used for controlling the break-make of whole testing cassete power supply, and button 2 is the button that can automatically upspring, button 2(K2 when pressing) closure, release button 2(K2) after disconnect immediately.Power light 3 and output indicator 4 are respectively used to the state of new number of the test of the break-make of display power supply and test lead.Described binding post 6 can be made the socket of two different colours, can adopt two kinds of colors of champac to carry out the polarity of distinguishing tests end.
As shown in Figure 2, in the internal circuit of place, power switch K1 controls the break-make of whole circuit, power light LED1 be connected into major loop after current-limiting resistance R1 connects, connect with button K2 after output indicator LED2 connects with current-limiting resistance R2 and then access major loop, calibrating terminal A1 is connected into node between button K2 and current-limiting resistance R2, and terminal A2 is connected with the negative pole of output indicator LED2.Current-limiting resistance is mainly used in current limliting, and resistance is 1K-10K.Select 5K at the present embodiment, it is the battery of 9V that power supply is selected voltage.
For convenience of description, its circuit diagram as shown in Figure 3.This circuit diagram comprises three loops altogether, first loop is powered by power supply E1, be external output loop, yellow binding post A1 is connected to the positive ends of a winding regulation of current transformer, blue binding post A2 is connected to the other end of a winding, when 1 dozen of K switch to co-bit, and during Push button K2, this loop conducting, externally output current; Second loop by power supply E3 power supply, is power supply indication loop, and when multicontact switch K1 beats to the conducting in this loop of co-bit, this moment, power light LED1 was bright; The 3rd loop by power supply E2 power supply, is output indication loop, and to co-bit, and button K2 presses lower time 1 dozen of K switch, this loop conducting, and this moment, output indicator LED2 was bright.More than the understanding to this circuit diagram.
