Abstract
The utility model provides a kind of automobile ignition switch connecting circuit, and comprise contact A CC, contact IG1, contact IG2 and contact ST, also comprise contact A M1 and contact A M2, described contact A M1 and contact A M2 is connected to circuit B+; When automobile key is in LOCK position, without connecting between contact; When automobile key is in ACC position, described contact A M1 connects described contact A CC, and other contacts are without connection; When automobile key is in ON position, described contact A M1 connects described contact IG1 and described contact A CC respectively, and described contact A M2 is connected to described contact IG2, and other contacts are without connection; When automobile key is in START position, described contact A M1 is connected to described contact IG1, and described contact A M2 is connected to described contact ST, and other contacts are without connection; Improve the life-span of ignition switch.
Description
Technical field
The utility model relates to a kind of automobile ignition switch connecting circuit.
Background technology
As shown in Figure 1, the connecting terminal at existing automobile ignition switch place, wherein contact A CC is connected to circuit ACC, and contact IG1 is connected to circuit IGN1, and contact IG2 is connected to circuit IGN2, contact A M is connected to B+ circuit, wherein circuit ACC, circuit IGN1 and circuit IGN2 are connected to each electrical equipment on automobile, and B+ circuit can to the circuit of electric power supply on automobile, when key position is in LOCK position, this position is key plug position, does not have connection; When key position is in ACC position, contact A CC is connected with contact A M, and the storage battery now on automobile is to some electric power supplies (such as broadcast receiver etc.) on car; When key position is in ON, car engine, now contact IG1, contact IG2, contact A CC and contact A M are interconnected, and now pass through circuit IGN1 and circuit IGN2 to the electric power supply on automobile; When automobile key position is in ST position, i.e. START position, the startup stage that now automobile being in, the IGN1 circuit at this time only having contact IG1 to connect and starter in running order, All other routes are in brief power outage state, and key of loosing one's grip after having started meeting automatic rebounding is to ON position; All loads of existing ignition switch all only give each line powering by contact A M, if load is too high, larger through contact A M electric current, easily cause contact temperature rise too high, and then cause the reduced lifetime of ignition switch, therefore need to do special surface treatment to each contact, this will improve entreprise cost greatly.
Summary of the invention
The technical problems to be solved in the utility model, is to provide a kind of automobile ignition switch connecting circuit, increases the life-span of ignition switch.
The utility model is achieved in that a kind of automobile ignition switch connecting circuit, and comprise contact A CC, contact IG1, contact IG2 and contact ST, also comprise contact A M1 and contact A M2, described contact A M1 and contact A M2 is connected to circuit B+;
When automobile key is in LOCK position, without connecting between contact;
When automobile key is in ACC position, described contact A M1 connects described contact A CC, and other contacts are without connection;
When automobile key is in ON position, described contact A M1 connects described contact IG1 and described contact A CC respectively, and described contact A M2 is connected to described contact IG2, and other contacts are without connection;
When automobile key is in START position, described contact A M1 is connected to described contact IG1, and described contact A M2 is connected to described contact ST, and other contacts are without connection.
Further, also comprise a fuse F1, described contact A M1 and contact A M2 is connected to circuit B+ by fuse F1.
The utility model has the advantage of: a kind of automobile ignition switch connecting circuit of the utility model, makes ignition switch not need just can greatly increase its useful life through special processing, reduce cost.
Accompanying drawing explanation
The utility model is further described with reference to the accompanying drawings in conjunction with the embodiments.
Fig. 1 is existing automobile ignition switch connecting circuit schematic diagram.
Fig. 2 is the utility model automobile ignition switch connecting circuit schematic diagram.
Embodiment
Refer to shown in Fig. 2, the utility model automobile ignition switch connecting circuit, comprise contact A CC, contact IG1, contact IG2 and contact ST, also comprise contact A M1 and contact A M2, described contact A M1 and contact A M2 is connected to circuit B+; Contact A M1 and contact A M2 draws respectively after wiring is finally summarised on single line bundle again and is connected to circuit B+, and now make contact A M1 be connected load respectively with contact A M2, reduce the load of contact A M1 and AM2, the electric current making it pass through is not too large;
When automobile key is in LOCK position, without connecting between contact;
When automobile key is in ACC position, described contact A M1 connects described contact A CC, and other contacts are without connection, and now circuit B+ can give the electric power supply on ACC circuit;
When automobile key is in ON position, described contact A M1 connects described contact IG1 and described contact A CC respectively, described contact A M2 is connected to described contact IG2, and other contacts are without connection, and now circuit B+ can give the electric power supply on IGN1 circuit, IGN2 circuit and ACC circuit;
When automobile key is in START position, described contact A M1 is connected to described contact IG1, and described contact A M2 is connected to described contact ST, and other contacts are without connection, and now circuit B+ can give the electric power supply on IGN1 circuit, and powers to starter motor.
The utility model also comprises a fuse F1, and described contact A M1 and contact A M2 is connected to circuit B+ by fuse F1.
Although the foregoing describe embodiment of the present utility model; but be familiar with those skilled in the art to be to be understood that; specific embodiment described by us is illustrative; instead of for the restriction to scope of the present utility model; those of ordinary skill in the art, in the modification of the equivalence done according to spirit of the present utility model and change, should be encompassed in scope that claim of the present utility model protects.
