Abstract
The utility model provides a socket used for power battery connection. The socket includes at least two electrodes used for electricity connection arranged on an insulation shell. One of the electrodes in the shell is a plug electrode having an outer surface connecting with electricity. The other electrode is a jack electrode having an inner surface connecting with electricity. An insulation layer is wrapped on an outer surface of the jack electrode. A plug matching with the socket for power battery connection includes at least two electrodes for electricity connection are arranged on an insulation base. One electrode in the base is a plug electrode having an outer surface connecting with electricity. An outer part of the plug electrode is an empty cavity used for fitting with the jack electrode of the socket. The other electrode is a jack electrode having an inner surface connecting with electricity. The insulation base is out of the jack electrode. The power source connection is realized through contact of the relatively adaptive plug electrodes having an outer surface connecting with electricity and the jack electrodes having an inner surface connecting with electricity in the plug and the socket. By using the plug and socket used for power battery connection in the utility model, problems of poor contact and short circuit caused by accident contact of the electrodes are solved.
Description
Technical field
The utility model relates to a kind of plug, socket, especially relates to a kind of electrokinetic cell and connects with plug, socket.
Background technology
At present, can following four kinds of power accumulators, i.e. VRLA maintenance free cell, gelled lead acid battery, nickel-hydrogen accumulator and lithium-ions battery be arranged by what electric motor car adopted.The electromobile battery output voltage mainly contains 36V, 48V, and indivedual occasions are used 60V, 72V even higher.
The charging of electromobile battery for ease, storage battery adopts dismountable mounting means in electric motor car usually, and existing way is:
Lead-acid battery of electric vehicle is joined socket, adopts existing common specifications model: three terminals or two-terminal structure, be convenient charging, and the part electric motor car installs circular poroid charge in batteries socket in addition additional.
Nickel-hydrogen accumulator and lithium-ions battery partly adopt the plugs and sockets of special construction.
For the plug that adopts for most of electric motor car, the socket, have great potential safety hazard, possibly cause unexpected contact short circuit accident, it is unreliable to contact.Touch the electric motor car charging socket like children with coin or metal analog, cause two interpolar short circuits, cause an explosion accident.Like electromobile battery socket end accidental short circuit incident (portable storage battery moves, and individual's metal object (like Metal buttons, jewelry, key etc.) accident on one's body touches the storage battery socket, causes two interpolar short circuits, and pyrophoricity accident sets off an explosion).The E terminal of plug, socket in most cases is unnecessary in addition, causes the wasting of resources.When needs increase anti-theft alarm function, can be directly at lead-in wire of corresponding terminal parallel connection output.
How to guarantee electromobile battery safer (avoiding the interelectrode unexpected contact short circuit of socket); Guarantee that the plugs and sockets contact is more reliable, connecting well is problem demanding prompt solution.
The utility model content
The purpose of the utility model provides a kind of electrokinetic cell and connects with plug, socket, solves the electrokinetic cell connection and avoids the interelectrode unexpected contact short circuit of socket and connect problem of poor with plug, socket.
The utility model solves the technical scheme that its technical problem adopted:
A kind of electrokinetic cell socket for connection, it is included on the housing of insulation 2 electrodes that connect electric usefulness are set at least, it is characterized in that: an electrode in the said housing is the plug electrode that outer surface connects electricity; Another electrode is the jack electrode that inner surface connects electricity, and described jack electrode outer surface is wrapped with insulating barrier.
Further, also be provided with 1 on the described insulation shell and get the signal electrode that the anti-theft alarm function signal is used.
Further, also be provided with 1 at least installs and fixes the hangers that socket is used to described insulation shell outward.
A kind of electrokinetic cell connects uses plug; Adaptive above-mentioned electrokinetic cell socket for connection; It is included on the pedestal of insulation 2 electrodes that connect electric usefulness is set at least; It is characterized in that: an electrode in the described pedestal is the plug electrode that outer surface connects electricity, and described plug electrode outside is the cavity of the jack electrode of adaptive socket; Another electrode is the jack electrode that inner surface connects electricity, and described jack electrode is outward the pedestal of insulation.
Power supply connect be through in plug, the socket each other the adaptive outer surface plug electrode that connects electricity and the inner surface jack electrode that connects electricity contact to be connected and realize.
The beneficial effect of the utility model: since power supply connect be through in plug, the socket each other the adaptive outer surface plug electrode that connects electricity and the inner surface jack electrode (being commonly called as yin-yang structure) that connects electricity contact to be connected and realize.Solved the problem of 3 aspects:
If 1, newly-designed electric motor car adopts above-mentioned plugs and sockets; Battery two electrodes separate fully, are monoyin and monoyang type structure, and one of them electrode is insulated the material parcel; Can avoid the unexpected contact short circuit accident that possibly cause between electrode fully, improve the security performance of plugs and sockets greatly.
2, increased the electrode electric clearance, reduced the short circuit or the insulation that possibly exist between the battery output port and descend and the self discharge loss of increase.Existing socket is inner if having into water or foreign matter exist, and promptly possibly cause between electrode electric clearance to reduce or short circuit takes place.
3, plug, tight more, the robust of socket contact.Existing electric motor car plugs and sockets is in the vibration of frequently jolting of the electric motor car process of riding, and it is loosening to cause that easily their connect, and causes loose contact, or causes work not normal, or strike sparks and cause fault.Though portioned product increases the card pressure part, operates cumbersome.The utility model plugs and sockets, two ends are monoyin and monoyang type structure, and directed guiding structure is arranged, guarantee easy to use, plugs and sockets contact more closely, robust.
Below will combine accompanying drawing and embodiment, the utility model will be carried out comparatively detailed explanation.

Embodiment
For the storage battery that only adopts positive and negative two electrode terminals as electric motor car car load power supply (no anti-theft alarm function) in the electric motor car, its plug, socket positive and negative electrode adopt one group of yin-yang structure formula.
For the socket of the electric motor car car load (anti-theft alarm function is arranged) of present employing three terminal power reguirements, its E terminal can be drawn link electrode in the inboard corresponding terminal parallel connection of socket.
For the electric motor car with double socket (storage battery accessory power outlet and charge in batteries input socket), its charging input plug socket is preferentially adopted the utility model structure.
