Abstract
The utility model discloses a misoperation-preventive multimeter, which comprises a multimeter body. The multimeter body is provided with a plurality of metering jacks used for inserting metering pens. The misoperation-preventive multimeter comprises an alarm control circuit, a vibration generator, jack ejecting devices and sensing switches, wherein the jack ejecting devices, the sensing switches and the metering jacks are all identical in number. One jack ejecting device is arranged at one metering jack, and one sensing switch corresponding to the jack ejecting device is arranged in the multimeter body. The alarm control circuit is respectively connected with the sensing switches and the vibration generator electrically. The misoperation-preventive multimeter is reasonable and skillful in structural design, reminds a user of difference between the metering jacks in which the metering pens are inserted and metering shift indication of the multimeter by vibration, so that the user can correct operation in time, and damage of the multimeter or personal harms of the user caused by misoperation are avoided.
Description
Technical field
The utility model relates to surveying instrument, particularly a kind of imitative maloperation multimeter, and when carrying out voltage or current measurement, if when the meter clerical mistake is inserted into the measurement jack of non-mistake, the automatic vibration alarming of this anti-misoperation multimeter.
Background technology
Multimeter is the most basic instrument in electronic surveying field, also is a kind of use surveying instrument widely.Multimeter is divided into pointer multimeter and digital multimeter, is a kind of multi-functional, multiple range measurement instrument.General multimeter can be measured DC current, DC voltage, alternating voltage, resistance and audio-frequency electric equality, all right test cross stream electric current, electric capacity, inductance value and more semi-conductive parameters of having.
In the prior art, man-made failure operation in use often takes place and causes instrument to be burnt in multimeter, especially in measurement electric current mistiming test pencil is inserted the voltage measurement jack and carries out voltage measurement, thereby cause the damage of multimeter; Be the damage that prevents that the multimeter faulty operation from causing, a lot of producers have released the buzzing warning, the LCD warning of glimmer, and voice prompt alarm or LED glimmer and note when different type of alarm such as warning comes prompting operation person that maloperation takes place.
Though above type of alarm widespread use, but have quite a few operator can ignore the warning of instrument, thus cause maloperation to make the damage that instrument takes place.Tracing it to its cause, mainly is because the type of alarm of these instrument all provides warning through sound or light to the user, if the user do not note, still can ignore alerting signal and produce maloperation.
And the workplace bigger at some noise or light is more intense is not easy to find sound or light warning signal equally.
The utility model content
The purpose of the utility model is; A kind of anti-misoperation multimeter is provided; Its reasonable in design is ingenious; Measurement jack through the mode of vibration reminds the measurement test pencil of user's multimeter to be inserted is different with the measurement gear indication of multimeter, thereby reminds the user in time to correct mistakes, and avoids faulty operation to cause instrument to damage perhaps the user is caused personal injury.
The utility model for realizing the technical scheme that above-mentioned purpose adopted is:
A kind of anti-misoperation multimeter; It comprises a universal meter body; In this universal meter body be provided with some be used to peg graft measure the measurement jack of test pencil; Its also comprise an alarm control circuit, a vibration machine, with the jack liftout attachment of said measurement jack equal number and with the inductive switch of said measurement jack equal number; A said jack liftout attachment is arranged at one and measures the jack place, and corresponding this jack liftout attachment of a said inductive switch is arranged in this universal meter body, and said alarm control circuit is electrically connected with this inductive switch, vibration machine respectively.
A said jack liftout attachment is arranged at the end or the sidewall of a measurement jack.
The quantity of said measurement jack is four.
Said vibration machine is the DC driven eccentric motor.
Said inductive switch is a touch-switch.
The beneficial effect of the utility model is: the utility model reasonable in design is ingenious; Measurement jack through the mode of vibration reminds the measurement test pencil of user's multimeter to be inserted is different with the measurement gear indication of multimeter; Thereby remind the user in time to correct mistakes, avoid faulty operation to cause instrument to damage perhaps the user is caused personal injury.
Below in conjunction with accompanying drawing and embodiment, the utility model is further specified.
Description of drawings
Fig. 1 is the modular structure synoptic diagram of the utility model.
Embodiment
Embodiment: see Fig. 1; A kind of anti-misoperation multimeter of the utility model; It comprises a universal meter body; In this universal meter body be provided with some be used to peg graft measure the measurement jack 1 of test pencil, its also comprise an alarm control circuit 2, a vibration machine 3, with the jack liftout attachment 5 of said measurement jack 1 equal number and with the inductive switch 4 of said measurement jack 1 equal number, a said jack liftout attachment 5 is arranged at one and measures jack 1 place; A said inductive switch 4 corresponding these jack liftout attachments 5 are arranged in this universal meter body, and said alarm control circuit 2 is electrically connected with this inductive switch 4, vibration machine 3 respectively.
A said jack liftout attachment 5 is arranged at the end or the sidewall of a measurement jack 1.When the meter penholder was gone into the measurement jack 1 of multimeter, meter Pen Association ejected jack liftout attachment 5, and this jack liftout attachment 5 can touch inductive switch 4, and alarm control circuit 2 is connected.
This alarm control circuit 2 is made up of logical circuit, the measurement jack 1 that is inserted when the measurement test pencil of multimeter and the measurement gear indication of multimeter not simultaneously, this alarm control circuit 2 is connected vibration machines 3, sends the vibration alarming signal.The measurement jack 1 that is inserted when the measurement test pencil of multimeter and the measurement gear of multimeter are indicated when identical, and then 2 of alarm control circuits are disconnected vibration machine 3, can not send the vibration alarming signal.
The quantity of said measurement jack 1 is four.
Said vibration machine 3 is the DC driven eccentric motor.
Said inductive switch 4 is a touch-switch, and the key stroke of this touch-switch is between 0.5mm-0.8mm.
The utility model reasonable in design is ingenious; Measurement jack 1 through the mode of vibration reminds the measurement test pencil of user's multimeter to be inserted is different with the measurement gear indication of multimeter; Thereby remind the user in time to correct mistakes, avoid faulty operation to cause instrument to damage perhaps the user is caused personal injury.
Embodiment is said like the utility model, and other anti-misoperation multimeters that obtain with the same or similar structure of the utility model are all in the utility model protection domain.
