Abstract
The utility model relates to a kind of circuit arrangement that adopts three needle-discharging screening ignition coil to lose efficacy, and this circuit arrangement comprises: Function generator, time switch, reometer, voltage table, accumulator, integration module, three needle-discharging modules; Described voltage table is in parallel with accumulator, for detection of the stability of circuit voltage; One end of described reometer is electrically connected to one end of time switch, and the other end and voltage table, accumulator are serially connected; The other end of time switch is connected in series with integration module; Described Function generator is electrically connected to integration module, and the pulse voltage that integration module produces Function generator sends ignition coil to by amplification; Because ignition coil is electrically connected to three needle-discharging modules, the high-tension electricity that ignition coil produces discharges by three pins.The utility model is simple in structure, easy to operate, can control by time switch the length of three needle-discharging times, can effectively carry out the detection screening of early stage cold run coil.
Description
technical field
The utility model belongs to auto parts and components and manufactures field, particularly a kind of circuit arrangement that adopts three needle-discharging screening ignition coil to lose efficacy.
Background technology
In use, easily there is the situation of early stage cold run in ignition coil.But how to detect the coil that produces early stage cold run, need a kind of special detection device just can reach Production requirement.
utility model content
The purpose of this utility model is to provide a kind of simple to operate and detect ignition coil failure mode testing circuit device accurately.
A circuit arrangement that adopts three needle-discharging screening ignition coil to lose efficacy, this circuit arrangement comprises: Function generator, time switch, reometer, voltage table, accumulator, integration module, three needle-discharging modules;
Described voltage table is in parallel with accumulator, for detection of the stability of circuit voltage; One end of described reometer is electrically connected to one end of time switch, and the other end and voltage table, accumulator are serially connected; The other end of time switch is connected in series with integration module; Described Function generator is electrically connected to integration module, and the pulse voltage that integration module produces Function generator sends ignition coil to by amplification; Because ignition coil is electrically connected to three needle-discharging modules, the high-tension electricity that ignition coil produces discharges by three pins.
The utility model is simple in structure, easy to operate, can control by time switch the length of three needle-discharging times, can effectively carry out the detection screening of early stage cold run coil.
accompanying drawing explanation
Fig. 1 is the structural representation that the utility model adopts the circuit arrangement of three needle-discharging screening ignition coil inefficacies.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
Figure l is the structural representation that the utility model adopts the circuit arrangement of three needle-discharging screening ignition coil inefficacies.For outstanding the utility model feature, in accompanying drawing, only expressed and the closely-related necessary assembly of the utility model content, and omitted other less important assemblies.A kind of circuit arrangement that adopts three needle-discharging screening ignition coil to lose efficacy, this circuit arrangement comprises: Function generator, time switch, reometer, voltage table, accumulator, integration module, three needle-discharging modules, voltage table is in parallel with accumulator, for the stability of test circuit voltage at any time.One end of reometer and one end of time switch link together, and the other end and voltage table, accumulator are serially connected.The other end of time switch is connected in series with integration module.Function generator is connected with integration module, the pulse voltage that integration module produces Function generator sends ignition coil to by amplification, and because ignition coil is electrically connected to three pins, the high-tension electricity that ignition coil produces discharges by three pins, during voltage breakdown between any two of three pins, discharge.Time switch, when controlling the whole testing circuit time, can carry out time setting as required.
During the utility model work, the ignition coil detection circuit for access first need being detected, was adjusted to for 1 min time by time switch, connected three needle-discharging power supplys, can carry out timing discharging to ignition coil.If there is ignition coil just no longer to discharge less than 1min discharge time, this coil is cold run coil.Operation is very easy for the utility model testing circuit device, can greatly increase work efficiency.
