Description
(1) technical field
The utility model relates to a kind of automobile with the two afterflow relays of big capacity, belongs to the auto electric technical field.
(2) background technology
In the existing cargo vehicle driving process is to control the break-make that a plurality of low capacity relays in parallel are realized required power supply in the driving process by a switch, the a plurality of relays of this employing are realized identical, sole purpose control mode with identical occupation mode, cause design loaded down with trivial details, during installation fee, be not easy to maintenance and manufacturing cost and increase.Simultaneously, relevant relay main contacts loop does not have the afterflow function, is unfavorable for the release of inductive element self-inductance power electromotive force, and along with the extensive use of various functional control modules on automobile, above situation has a negative impact to the relevant controlling module.
(3) summary of the invention
The utility model is at the deficiencies in the prior art, provides a kind of automobile rational in infrastructure, functional, easy for installation with the two afterflow relays of big capacity.
The utility model adopts following solution:
The two afterflow relays of this big capacity comprise rivet, relay cover, relay base, the standard metal plug, control coil loop continued flow resistance, loop, contact continued flow resistance, fuse, control switch travels, relay coil and relay contact, wherein, control coil loop continued flow resistance is in parallel with control coil, its two ends are connected with the standard metal plug respectively, control coil is connected with Relay base by rivet, Relay base is connected with relay cover, the relay contact two ends are connected with the standard metal plug respectively, loop, contact continued flow resistance is connected with the standard metal plug respectively, control switch one end that travels is connected with fuse, and the other end is connected with the standard metal plug.
Locate slotted hole on the Relay base.
Relay cover is a metal material.
All be connected the standard metal plug at control coil loop continued flow resistance with loop, contact continued flow resistance.
Use the utility model to design enough make-break capacity and capacity, practical requirement according to the actual conditions of car load electrical system; Relay cover is adopted metal material, be convenient to heat radiation; Control coil loop continued flow resistance all is connected the standard metal plug with loop, contact continued flow resistance, is convenient to peg graft, fix with outside relative assembly; The resistance that the two afterflow relay design of big capacity are used be convenient to this relay stop using form from or the controlled member continuous current circuit.The utility model is finished the control of required power supply in the vehicle traveling process by such scheme, so-called two afterflow, be exactly not only the relay control coil design to be had from continuous current circuit, also for the inductive element design that is controlled by main contacts has continuous current circuit, so improve the Electro Magnetic Compatibility of car load electrical system simultaneously.Also have advantages such as rational in infrastructure, functional, easy for installation.

Fig. 2 is the utility model left view;
Fig. 3 is the utility model vertical view;
Fig. 4 is the utility model circuit diagram.
Wherein: 1, rivet, 2, relay cover, 3, Relay base, 4, loop, contact continued flow resistance, 5, control coil loop continued flow resistance, 6, control coil, 7, fuse, 8, the control switch that travels, 9, relay contact, 11,12 is 6.3 * 0.8mm standard metal plug, and 10,13 is 9.5 * 1.2mm standard metal plug.
(5) embodiment
Embodiment: structure as shown in Figure 1, Figure 2, Figure 3 and Figure 4.Form by rivet 1, relay cover 2, Relay base 3, loop, contact continued flow resistance 4, control coil loop continued flow resistance 5, control coil 6, fuse 7, the control switch 8 that travels, relay contact 9, standard metal plug 10,11,12,13.Control coil loop continued flow resistance 5 is connected with standard metal plug 11,12 respectively with control coil 6 its two ends in parallel, control coil 6 is connected with Relay base 3 by rivet 1, Relay base 3 is connected with relay cover 2, standard metal plug 10 is connected with relay contact 9 one ends, appliance contact 9 other ends are connected with standard metal plug 13, and loop, contact continued flow resistance 4 is connected with standard metal plug 11,13 respectively.In addition, Relay base 3 has the location slotted hole, is convenient to standard metal plug 10,11,12,13 and is connected with internal resistance or control coil by pegging graft with outside relative assembly behind the slotted hole location, location.Concrete enforcement is as follows: standard metal plug 10 is connected with the DC24V power supply by fuse 7, control switch 8 one ends that travel are connected with fuse 7, the other end is connected with standard metal plug 12, standard metal plug 11 ground wires connect, and standard metal plug 13 control switch or power consumption equipment in travelling provide power supply.When running car, control switch 8 closures of travelling, control coil 6 electric, relay contact 9 is closed under magneticaction, automobile-used DC24V power supply needs the control switch that uses or provides power supply with electrical component by relay contact 9 in travelling; When the control switch 8 that travels disconnects, control coil 6 dead electricity, relay contact 9 disconnects, automobile-used DC24V stops to the relevant controlling switch or uses the electrical component power supply, the self-induced e.m.f that produced of this relay control coil 6 formed loops by control coil loop continued flow resistance 5 and discharged this moment, and the self-induced e.m.f that produced by the perceptual electricity consumption device of these relay contact 9 controls forms loops by loop, contact continued flow resistance 4 and discharges.Thereby reduce relevant perceptual electricity consumption device in the impact of outage, improve the Electro Magnetic Compatibility of car load electrical system the car load electrical system.
