Abstract
The utility model discloses a kind of ignition switch line construction, the AM1 interfaces of ignition switch are through the first wire connecting power, AM2 interfaces through the second wire connecting power, IG2 output interfaces connection privates one end of the ignition switch, the privates other end connects privates one end and the 5th wire one end respectively, the privates other end connects starting relay, the 5th wire other end connects and is equipped with fuse on ECU, first wire and the second wire.ECU starting protection circuits are protected to have the load circuit that can protect IG2 simultaneously the utility model has the advantage of IG2 insurance; in addition; line footpath all the way from safety box to ignition switch can diminish; playing drop, this is acted on lightweight; it can diminish from the IG2 load line footpaths exported, can reach and drop this and light-weighted effect.
Description
Technical field
The utility model is related to automotive wire bundle principle and power distribution field.
Background technology
What current automobile power source distributed to ignition switch is all mostly to insure all the way, and ignition switch is held because of the contact of itself
Current-carrying capability problemses, many at present using 2 points of forms shunted, that is, the part for receiving power supply is divided into two contacts, Ci Zhongdian
Fire switch needs power supply to divide two-way to ignition switch after being come out from electrical appliance kit.
Current caused situation of insuring all the way is that the two-way wire diameter for giving ignition switch must be consistent, and is all needed
With big line footpath wire, otherwise wire can not then be protected.At present because the electricity on ignition switch IG2 must be protected to ECU startup
One input of shield, and ECU connector can not crimp the wire of big line footpath, therefore need to give ECU starting protections one single line
Road is protected, and adds an insurance to protect this circuit on ECU starting protection circuit.Such a situation and increased wire harness
Cost has aggravated the weight of wire again.
Utility model content
Technical problem to be solved in the utility model is to realize that one kind can reduce ignition switch connection circuitry weight, and
The ignition switch line construction of wire cost can be reduced.
To achieve these goals, the technical solution adopted in the utility model is：A kind of ignition switch line construction, igniting
The AM1 interfaces of switch are through the first wire connecting power, AM2 interfaces through the second wire connecting power, and the IG2 of the ignition switch is defeated
Outgoing interface connection privates one end, the privates other end connects privates one end and the 5th wire one end respectively,
The privates other end connects starting relay, and the 5th wire other end connects ECU, first wire and second
Fuse is equipped with wire.
Fuse on first wire is that the fuse on 30A, second wire is 10A.
The line footpath of first wire is 2.5mm2, the line footpath of second wire is 0.5mm2。
The line footpath of the privates, privates and the 5th wire is 0.5mm2。
ECU starting protection circuits are protected to have the load that can protect IG2 simultaneously the utility model has the advantage of IG2 insurance
Loop, in addition, the line footpath all the way from safety box to ignition switch can diminish, playing drop, this is acted on lightweight, from IG2 outputs
Load line footpath can diminish, drop this and light-weighted effect can be reached.
Brief description of the drawings
The mark in the content and figure of every width accompanying drawing expression in the utility model specification is briefly described below：
Fig. 1 is ignition switch line construction schematic diagram；
Mark in above-mentioned figure is：1st, the first wire；2nd, the second wire；3rd, privates；4th, privates；5th, the 5th
Wire.
Embodiment
As shown in figure 1, ignition switch line construction mentions the insurance of ECU starting protections the contact all the way of ignition switch
Before, two contacts for insuring protection ignition switch respectively with two-way are inputted.I.e. the AM1 interfaces of ignition switch connect through the first wire 1
Power supply is connect, the AM2 interfaces of ignition switch connect power supply through the second wire 3, are equipped with the first wire 1 and the second wire 3
Fuse, wherein the line footpath of the first wire 1 is 2.5mm2, the line footpath of the second wire 3 is 0.5mm2, the insurance on the first wire 1
Silk is that the fuse on 30A, the second wire 3 is 10A.
Power distribution in power distribution on IG2 is all that small-power is responsible for, therefore the wire diameter on IG2 can drop
Low, the insurance of selection can meet the load protection on IG2 while protection ECU starting protection wire loops can also be met.I.e.
IG2 output interfaces connection privates 3 one end of ignition switch, the other end of privates 3 connect respectively the one end of privates 4 and
The one end of 5th wire 5, the other end of privates 4 connection starting relay, the other end of the 5th wire 5 connection ECU, privates 3,
The line footpath of the wire 5 of privates 4 and the 5th is by original 2.5mm2It is changed into 0.5mm2。
Above-mentioned line construction has sufficient theoretical validation, and whether the connector adaptation terminal of such as ignition switch can crimp
Small line footpath wireBy information inquiry, the connector of this ignition switch is can to crimp the small line selected by such a connection method
The wire in footpath.The line footpath of starting protection and line footpath to starting relay can be consistent, such such a power distribution in surface
Method can be implemented completely, can also so reduce wire cost and play lightweight effect.
The present invention is exemplarily described above in conjunction with accompanying drawing, it is clear that the utility model is implemented not by above-mentioned
The limitation of mode, if the improvement of the various unsubstantialities of inventive concept and technical scheme of the present invention progress is employed, or not
It is improved by the present invention design and technical scheme directly apply to other occasions, protection domain of the present utility model it
It is interior.
