Description
Technical field
The present invention relates to a kind of charging device of having prevented spark.
Background technology
Traditional plug is in being inserted into socket time, because electric current is directly carried on the electric elements of power consumption equipment, and because electric elements are short to the time that adds full voltage by zero load, voltage is large, when plug and socket also have very little gap, can be by air ionization, so moment has produced spark, when power consumption equipment power ratio is larger, can produce larger spark and produce a large amount of heats patching moment, can be by plug or little by little ablation of socket, and power consumption equipment is produced to harm, the human body etc. of also may burning, if especially firmly irregular when inserting, logical state when disconnected while easily producing, power consumption equipment is difficult to bear the repeatedly impact of so large electric current, cause power consumption equipment to burn.
Summary of the invention
The object of the present invention is to provide the safer charging device of having prevented spark of a kind of use.
In order to realize object of the present invention, the technical scheme of taking is:
A charging device of having prevented spark, comprising:
Retractor device, retractor device comprises fixed part and motion portion;
Drive unit, for driving the motion portion of retractor device;
Plug, plug comprises plug insulating base, the long contact of charging, short contact, signal contact charge, plug insulating base is connected with motion portion, charge long contact, the short contact that charges, signal contact is installed in plug insulating base and stretches out in plug insulating base, the extension elongation of short contact of charging is greater than the extension elongation of signal contact, and the extension elongation of the short contact that charges is less than the extension elongation of the long contact of charging;
Detector, for detection of the advanced positions of plug;
Controller, for receiving information that detector detects the running status of accessory drive.
Controller sends signal to drive unit, drive unit is started working, thereby drive the motion portion motion of retractor device, and then drive plug to do rectilinear motion, the long contact of charging in plug, short contact charges, signal contact is followed plug and is done together rectilinear motion, because the extension elongation of the long contact of charging is greater than the extension elongation of the short contact that charges, the extension elongation of short contact of charging is greater than the extension elongation of signal contact, therefore, the order that touches the electrode in socket is, first then the long contact of charging is the short contact of charging, it is finally signal contact, when signal contact touches the electrode on socket, plug is just switched on, realized full-automatic charging, only have after three contacts are stable and just can switch on, therefore, plug is connected after electricity, the contact stabilization of contact and electrode, there is not gap, can prevent that plug from occurring spark in inserting socket process, use safer, there will not be plug, the situation that socket or load equipment are burnt.
Below technical scheme is further illustrated:
Preferably, described plug also comprises three Compress Springs, described plug insulating base is provided with three through holes, charge long contact, charge short contact, signal contact is placed in respectively in each through hole, three Compress Springs are sheathed on respectively one end that the long contact of charging, the short contact that charges, signal contact are positioned at plug insulating base, charge on long contact, charge short contact, signal contact and be equipped with projection, Compress Spring two ends wind do not conflict projection and plug insulating base.Compress Spring can make to charge long contact, the short contact that charges, more firm being attached on electrode of signal contact, thereby use safer, projection on Compress Spring one end conflict insulating base other end conflict contact, thereby give, touch first thrust, contact is better contacted with electrode, because three contacts are not contact electrodes simultaneously, when the long contact of charging is first after contact electrode, the existence of the Compress Spring long contact of being convenient to charge has certain compression surplus, until signal contact contact electrode.
