Description
Technical field
The present invention relates to vehicle circuit field, in particular to a kind of automobile-used counnter attack connection device.
Background technology
Accumulator on vehicle is a kind of device converting chemical energy into electric energy, belongs to DC power supply, its effect has：
(1) when starting engine, powerful starting current (generally up to 200~600A) is provided to starter.(2) work as generator overload
When, generator can be assisted to power supply for electrical equipment.(3) when engine is in idling, to power supply for electrical equipment.(4) electric power storage
Pond or a large value capacitor, can protect the electrical appliance of automobile.(5) when generator voltage is higher than the electricity of lead accumulator
When kinetic potential, a part of electric energy is changed into chemical energy and is stored, that is, is charged.Due to accumulator plus-minus polar plate material
Difference, other than active material, negative plate also added the materials such as barium sulfate, humic acid, carbon black and rosin, for preventing cathode
Plate is shunk and oxidation.In addition, much more a piece of the negative plate number of each single lattice accumulator is again always than positive plate number, and negative plate ratio
Positive plate is thin.When carry out accumulator initial charge or boost charge when, if not paying attention to polarity, accumulator can be made to fill instead, make just,
Cathode nearly all becomes coarse grained PbSO4, and battery charge off-capacity, cisco unity malfunction is caused to even result in electric power storage
It scraps in pond.Therefore, certain when charging it is noted that polarity, can't polarity fill instead.
When vehicle launch, it is understood that there may be accumulator capacity deficiency leads to not the case where starting vehicle.Electrical system at present
Design is mounted with external initiation socket, and when accumulator capacity deficiency, external initiation can be used.Since vehicle use environment is disliked
Bad, external initiation socket positive and negative anodes mark is often covered by spot, causes to identify unintelligible, is easy positive and negative anodes connection error,
Insurance even battery may be burnt in this way.
In addition, it is reversed to be also easy to cause positive and negative anodes since binding post shape is just the same for accumulator anode and cathode.Do not preventing
When reversal connection measure, positive and negative anodes are reversed to bring destructive consequence to vehicle power distribution box and electrical equipment.Therefore, how effectively anti-
Only positive and negative anodes reversal connection is urgent problem at this stage.
Invention content
In view of the deficiencies of the prior art, the object of the present invention is to provide a kind of automobile-used counnter attack connection devices, solve vehicle and use
Accumulator or using when battery pack, power supply are powered outside vehicle, due to power supply opposite voltage pair caused by positive and negative anodes connection error
The injury of electrical equipment enables block terminal and electrical equipment preferably to be protected, and ensure that the safe and reliable fortune of electrical system
Row.
For the purpose for realizing above-mentioned, the present invention provides a kind of automobile-used counnter attack connection devices, including：Car body, external start insert
Seat, master switch, accumulator, contactor I and contactor II；The car body, the external startup socket and contactor I series connection
Constitute circuit 1, the master switch, the accumulator and the circuits 2 in series the contactor II, the accumulator, block terminal,
Electrical equipment and the vehicle body in series constitute circuit 3；
The circuit 1, the circuit 2 and the circuit 3 the composition automobile-used counnter attack connection device in parallel.
Preferably, the contactor I is to be connected with line packet I by diode D1, then composed in parallel with switch S1.
Preferably, the contactor II is to be connected with line packet II by diode D2, then composed in parallel with switch S2.
Preferably, it connects between the car body and the block terminal electrical equipment.
Preferably, the external socket that starts starts client cables connection with external.
Compared with the immediate prior art, excellent effect of the invention is：
The present invention provides a kind of automobile-used counnter attack connection device, can complete the anti-reverse of entire automobile electric system, can effectively reduce whole
Vehicle circuit safety hidden danger.The present invention has fully considered the factors such as the handling characteristics of vehicle, performance, for the electricity of current electrical system
Road feature is improved, and when positive and negative anodes reversal connection, contactor is not attracted, and circuit does not work, and avoids the opposite voltage pair of power supply
The injury of electrical equipment enables block terminal and electrical equipment preferably to be protected, and ensure that the safe and reliable fortune of electrical system
Row.

Specific implementation mode
Below in conjunction with attached drawing, technical solution in the embodiment of the present invention carries out clear, complete description.
As shown in Figure 1, the present invention provides a kind of automobile-used counnter attack connection device, the counnter attack connection device includes：It is car body 1, outer
Portion starts socket 2, master switch 3, accumulator 4, contactor I5 and contactor II6.
It is with external initiation private cable that external initiation socket is positive and negative when vehicle uses external accumulator group or power supply power supply
Pole is connect with 24V battery packs positive and negative anodes outside vehicle respectively.Then block terminal and electrical equipment power on.
Contactor I5 is added between external initiation socket anode and car body in invention, and line packet I connects with diode D1；
Diode D2 is installed in contactor II6.It can just work when contactor I is only battery-powered outside using vehicle, for vehicle
Power supply under normal condition does not have an impact.The diode D2 installed additional on line packet II for vehicle normal use also without any
It influences.When vehicle is proper use of or proper use of externally fed, contactor I5 and contactor II6 normal ONs, entire electricity
Gas system normal operation.
When accumulator anode and cathode is reversed, due to the one-way conduction performance of diode, even if master switch can if connecting circuit
Ended, line packet II is failure to actuate, and vehicle cannot power on, and can be implemented in this way to block terminal and electrical equipment by using diode
Protection, until when the positive and negative anodes wiring of accumulator is correct, electrical system could restore normal.
When power external starting socket positive and negative anodes are reversed outside vehicle, due to the one-way conduction performance of diode, circuit can quilt
Cut-off, line packet I are failure to actuate, and vehicle cannot power on.Protection is implemented by using diode pair block terminal and electrical equipment, until outer
When portion's starting socket positive and negative anodes wiring is correct, electrical system can just restore normal.
Finally it should be noted that：The above embodiments are merely illustrative of the technical scheme of the present invention and are not intended to be limiting thereof, to the greatest extent
Invention is explained in detail with reference to above-described embodiment for pipe, and those of ordinary skill in the art still can be to this hair
Bright specific implementation mode is modified or replaced equivalently, and any modification without departing from spirit and scope of the invention or is waited
With replacing, applying within pending scope of the presently claimed invention.
