Abstract
The present invention discloses vehicle used automatically dropping type power supply plugging device. It contains plug, vehicle ignition switch starting up device, socket connected with external power supply, said socket consisting of watertight cover, dropping proof buckle, conductive contact, and terminal; said socket watertight cover connected with socket casing by spring hinge. It features: said automatically dropping type power supply plugging device also including electromagnet having works contactor, spring respectively set between socket conductive contact and terminal and inside track of socket casing; the contacting mode of said socket conductive contact with plug conduction column being point contact; magnet coil connected with vehicle ignition switch starting up device; when said plug inserts into socket, said electromagnet mounting position being just the position capable of making its working contactor topping out dropping proof bucket. The present invention overcomes current technologic shortage, capable of making vehicle automatically separating with external power supply, ensuring vehicle rapid starting.
Description
Technical field
The present invention relates to a kind of electric power connecting device, particularly disclose a kind of automatic dropping electric power connecting device.
Background technology
At present, the vehicle of parking for a long time and need coming into prompt action, with the fire fighting truck is example, its storage battery is discharge automatically when not using for a long time, when the voltage of storage battery is lower than 12V/24V, vehicle just can't normally start, so fire fighting truck necessarily requires the moment to keep enough electric weight, to guarantee normally setting out timely of fire fighting truck.And the original socket that links to each other with external power supply, artificially craft be pulled out fire fighting truck is separated with external power supply, and not only trouble has also been wasted the time of starting.
Summary of the invention
Technical problem to be solved by this invention is to overcome defective in the above-mentioned prior art, the electric power connecting device that provides a kind of external power supply can come off automatically when vehicle launch.
The present invention is achieved in that a kind of automobile-used automatic dropping electric power connecting device, comprise plug, vehicle ignition switch starting up device, the socket that is connected with external power supply, described socket is made up of waterproof cover, anti-tripping, conductive contact, terminals, the waterproof cover of described socket is connected by spring hinge with the shell of socket, it is characterized in that: described automatic dropping electric power connecting device also comprises the electromagnet that is provided with working contact, between described socket conductive and the terminals, the inner ring of jack housing is respectively equipped with spring; The way of contact of the conductive pole of described socket conductive and plug is a point contact type; Electromagnet coil is connected with vehicle ignition switch starting up device; When described socket and plug plugged together, the installation site of described electromagnet can make its working contact back down on the anti-tripping position.
When described socket and plug plugs together, the described anti-tripping plug base upper bottom surface that fastens, the installation site of electromagnet is positioned on the position below anti-tripping its working contact, and anti-tripping and work of electromagnet contact standoff distance are in work of electromagnet contact impulse stroke scope.
When described socket and plug plugged together, the anti-tripping and spring hinge of described socket was on same horizontal line.
Described socket conductive is a silver contact, and the conductive pole of described plug is silver-plated.
When vehicle launch, electromagnet produces magnetic, and the work of electromagnet contact is upwards the anti-tripping jack-up of socket waterproof cover, makes anti-trippingly to separate with plug, socket is ejection automatically just, thereby has realized the purpose that vehicle and external power supply separate automatically.
The invention has the beneficial effects as follows: the defective that has overcome prior art, vehicle is separated automatically with external power supply, guaranteed setting out fast of vehicle, can prevent to forget the accident of cutting off the electricity supply and causing because of the people, not only save time but also simple and direct manually-operated trouble, meet the standard of zero tolerance.

Embodiment
Further specify operation principle of the present invention below in conjunction with accompanying drawing as a kind of embodiment.
As shown in Figure 1 and Figure 2, waterproof cover 3 is connected with jack housing by spring hinge 8, waterproof cover 3 under the effect of spring hinge 8, when waterproof cover 3 is not subjected to external force and jack housing be kept closed; When forcing in waterproof cover 3, waterproof cover 3 is that movement in a curve is done in the center of circle with spring hinge 8.Silver contact 2 is positioned at jack 12, and jack spring 1 is fixed on the terminals 10, is connected by lead 9 between silver contact 2 and the terminals 10.
As shown in Figure 3, electromagnet 5 is fixed on plug base 6 one sides, work of electromagnet contact 7 is lower than plug base 6, when socket and plug plugs together, waterproof cover 3 is pressed in the upper bottom surface of plug base 6, and anti-tripping 4 fasten the upper bottom surface seamed edge of plug base 6, is higher than plug base 6 to upper process when 7 work of work of electromagnet contact, push anti-tripping 4, waterproof cover 3, back down anti-tripping 4.Work of electromagnet contact 7 will make plug, socket back down in conjunction with firm anti-tripping 4; other forms can be arranged; if position of anti-tripping 4 conversion; electromagnet 5 installation sites are change thereupon also; it is identical that work of electromagnet contact 7 backs down anti-tripping principle, and protection of the present invention is as the criterion with claim.In addition, the fundamental parts of described plug, socket is the commercially available prod, is commonly called as plug for industrial use, industrial socket, and the constitutional detail of its characteristic is creation of the present invention.
The present invention in use, terminals 10 are connected with external power supply, electromagnet coil one end 11 is connected with vehicle ignition switch starting up device, the electromagnet coil other end 16 ground connection; Plug is engaged with socket, and under the active force of spring 1, silver-plated conductive pole 13 closely contacts with silver contact 2; Fasten plug base 6 with anti-tripping 4, at this moment, work of electromagnet contact 7 aims at anti-tripping 4.When vehicle motor started, electromagnet 5 produced magnetic, and work of electromagnet contact 7 is upwards with anti-tripping 4 jack-up, and anti-tripping 4 separate with plug base 6, and under the active force of spring 15, socket outwards ejects, and causes socket and plug to separate fully.
