Abstract
The utility model discloses a chip tantalum capacitor measuring tool, and belongs to a device for measuring chip tantalum capacitors, and an objective is to provide a capacitor measuring device which would not cause an outgoing line of a capacitor product damaged. The tool comprises a measuring meter, a discharging resistor, and a fixture which are provided with a power supply. A double control switch (3) is fixed on a base (2). The measuring meter (9) and the discharging resistor (8) are respectively connected on two output ends of the double control switch (3). The measuring meter (9) is connected in parallel with the other end of the discharging resistor, and then the measuring meter and the discharging resistor are electrically connected with an input end of the double control switch (3) through a fixture (4). A pedal (1) hinged on the base (2) is disposed above the double control switch (3). A spring (6) fixed on the base (2) is disposed on a back side of the pedal. The tool thoroughly prevents discharging ignition phenomenon since a conventional measuring fixture cannot synchronously contact with two poles of a capacitor. The tool is used to measure chip tantalum capacitors.
Description
Technical field
The utility model relates to a kind of technological equipment, relates in particular to a kind of for measuring the device of chip tantalum capacitor.
Background technology
As everyone knows, for guaranteeing the q&r of chip tantalum capacitor product, in production run, need its performance test of leaking electricity; At present, conventionally adopt the fixture that is electrically connected to measurement instrument to the measurement of charging one by one of chip capacitor device product, and then by discharge fixture, it is discharged.Owing to being difficult to guarantee that discharge fixture synchronizes and contact with the two poles of the earth of capacitor product, usually cause the sparking that sparks, thereby cause the extension line of capacitor product impaired, affect product quality.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model aims to provide a kind of impaired chip tantalum capacitor of capacitor product extension line that can not cause and measures frock.
To achieve these goals, the utility model by the following technical solutions: it comprises measurement instrument, discharge resistance and fixture with power supply; Double control switch is fixed on base, and measurement instrument and discharge resistance are connected on respectively two output terminals of double control switch, after the other end parallel connection of this measurement instrument and discharge resistance, by fixture, are electrically connected to the input end of double control switch; The top of double control switch is the pedal being hinged on base, and there is the spring being fixed on base at the back side of this pedal.
Below pedal, there is the Limit screw being fixed on base.
Therefore compared with the prior art, the utility model, owing to having adopted technique scheme, has increased the double control switch being electrically connected to fixture, measurement instrument and discharge resistance, can guarantee that fixture synchronizes and contact with the two poles of the earth of capacitor while discharging; Thoroughly avoid traditional measurement fixture not synchronize with the two poles of the earth of capacitor and contacted and the phenomenon of guiding discharge sparking, can not damage capacitor product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that A in Fig. 1 is to view;
Fig. 3 is circuit theory diagrams of the present utility model.
In figure: pedal 1, base 2, double control switch 3, fixture 4, measured capacitance device 5, spring 6, Limit screw 7, discharge resistance 8, measurement instrument 9.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail:
As shown in Figures 1 to 3: double control switch 3 is fixed on base 2, the top of this double control switch is the pedal 1 being hinged on base 2, and there is the spring 6 being fixed on base 2 position near front end below this pedal.The positive pole of measurement instrument 9 by wire be connected with an output terminal of double control switch 3, one end of discharge resistance 8 is connected with another output terminal of double control switch 3 by wire, the negative pole of measurement instrument 9 is electrically connected to the input end of double control switch 3 by the fixture 4 of pincer-like afterwards with the other end parallel connection of discharge resistance 8.
For fear of exerting oneself excessive, double control switch 3 is damaged by pressure, below pedal 1, have the Limit screw 7 being fixed on base 2; The height of adjusting this Limit screw is the stroke that adjustable pedal 1 is depressed, to adapt to the double control switch 3 of different size.
During work, measured capacitance device 5 is held between the bipod of fixture 4, depresses normally closed contact that pedal 1 can disconnect double control switch 3, connect the normally opened contact of opening double control switch 3, so 9 pairs of measured capacitance devices 5 of measurement instrument charge, measure; After measurement, unclamp the normally opened contact that pedal 1 can be connected out the normally closed contact of double control switch 3, open double control switch 3, so can discharge to measured capacitance device 5 by discharge resistance 8.
Claims (2)
1. chip tantalum capacitor is measured a frock, comprises measurement instrument, discharge resistance and fixture with power supply; It is characterized in that: double control switch (3) is fixed on base (2), measurement instrument (9) and discharge resistance (8) are connected on respectively two output terminals of double control switch (3), and the other end parallel connection of this measurement instrument and discharge resistance is electrically connected to the input end of double control switch (3) by fixture (4) afterwards; The top of double control switch (3) is the pedal (1) being hinged on base (2), and there is the spring (6) being fixed on base (2) at the back side of this pedal.
