Abstract
The utility model relates to a wire harness overload automation protection device. The device comprises a vehicle-mounted power supply, a battery main switch, an electromagnetic main switch and an overload protector. The vehicle-mounted power supply, the battery main switch, an electromagnetic main switch coil and the overload protector form a control circuit. The vehicle-mounted power supply, an electromagnetic main switch contact point, the overload protector and all automotive electric appliances form a main circuit. By using the wire harness overload automation protection device of the utility model, a spontaneous combustion event caused by automobile line aging or human error operation can be effectively avoided so that human life and property can be effectively protected from losses.
Description
Technical field
The utility model relates to a kind of car electrics accessory, and a kind of circuit overloads that prevents specifically is to prevent the wire harness overload automatic protection apparatus of automobile circuit overload.
Background technology
Along with the development of society, the progress of science and technology, human lives's demand, more and more full automatic vehicle product releases greatly improve the problems such as human trip, logistics transportation to market.Although car electrics have all added fuse link or fusible link is protected, there is every year the self-burning of vehicle event to occur, cause the heavy losses that are difficult to remedy.The automobile industry data shows that most initial roots on fire are electrical equipment wiring harness short circuit (except accidents), causes the heating of wire harness overcurrent to form on fire.Not fusing of fuse link after the process expert inspection of the scene of a crime has a small part wire harness to catch fire.The more serious unprofessional driver of part that has replaces fuse link with thick copper lines after fuse link fusing.
Summary of the invention
The utility model proposes a kind of wire harness overload automatic protection apparatus for the shortcoming and defect that exists in the prior art, thereby can effectively prevent because the spontaneous combustion event that automobile line is aging or the manual operation mistake causes.
In order to solve the problems of the technologies described above, the utility model has adopted following technical scheme:
A kind of wire harness overload automatic protection apparatus comprises vehicle power, battery main switch, electromagnetism master switch, overload protective device, it is characterized in that consisting of control circuit by vehicle power, battery main switch, electromagnetism master switch coil and overload protective device; Consist of main circuit by vehicle power, electromagnetism master switch contact, overload protective device, full vehicular electrical appliance.
As preferably, also be provided with the battery main switch insurance on the described control circuit, and it is arranged between positive source and the electromagnetism master switch coil.
As preferably, also be provided with the large insurance of complete automobile-used two-way on the described main circuit.
As preferably, described wire harness overload automatic protection apparatus also has Tachographs, and described Tachographs is connected with described overload protective device.
When electric current is excessive when reaching protector operating value (large I arbitrarily transfer), protector work disconnects normally closed some electromagnetism master switch coil losing electricity; major loop disconnects; full car outage, vehicle is flame-out to be stopped to travel, and protector is often made war and closed signal is passed to Tachographs simultaneously.Tachographs stores fault message once; after pending fault is got rid of; protector automatically reset (about five, six minutes) normally closed closed; closed battery main switch can start normal vehicle operation again; if do not fix a breakdown, protector disconnects again and again, Operating In Persistent Current Mode after about five, six minutes.Tachographs stores corresponding failure information.
Wire harness overload automatic protection apparatus of the present utility model can effectively prevent because the spontaneous combustion event that automobile line is aging or the manual operation mistake causes effectively protects people's lives and properties not suffer a loss.
Description of drawings
Accompanying drawing 1 is the electrical block diagram of wire harness overload automatic protection apparatus of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, the wire harness overload automatic protection apparatus of present embodiment, comprise vehicle power, battery main switch 10, electromagnetism master switch 20, overload protective device 30, wherein consist of control circuit by vehicle power, battery main switch 10, electromagnetism master switch coil and overload protective device 30; Consist of main circuit by vehicle power, electromagnetism master switch contact, overload protective device 30, full vehicular electrical appliance.Also be provided with battery main switch insurance 40 on the described control circuit, and it is arranged between positive source and the electromagnetism master switch coil.Also be provided with the large insurance 50 of complete automobile-used two-way on the described main circuit.Described wire harness overload automatic protection apparatus also has Tachographs 60, and described Tachographs 60 is connected with described overload protective device.Too much when load 70, electric current is excessive when reaching protector operating value (large I is arbitrarily transferred), protector work; disconnect normally closed some electromagnetism master switch coil losing electricity, major loop disconnects, full car outage; vehicle is flame-out to be stopped to travel, and protector is often made war and closed signal passed to Tachographs simultaneously.Tachographs stores fault message once; after pending fault is got rid of; protector automatically reset (about five, six minutes) normally closed closed; closed battery main switch can start normal vehicle operation again; if do not fix a breakdown, protector disconnects again and again, Operating In Persistent Current Mode after about five, six minutes.Tachographs stores corresponding failure information.
The above; it only is preferred embodiment of the present utility model; can not be interpreted as limiting scope of the present utility model with this, the execution mode of all distortion that is equal to of making in the claimed scope of claims of the present utility model and change is all in the utility model scope required for protection.
