Description
Technical Field
The invention belongs to the technical field of connection of power supplies and electrical appliances of automobiles. More particularly, the present invention relates to an electrical box for an automotive engine compartment.
Background
The electrical box is mainly used for distributing automobile power, providing fuses and drives for a load loop of the whole automobile and carrying out centralized management on the fuses and the drives.
At present, an electrical box used in an automobile is of a hard-wire type structure or a PCB type structure. The components (fuses, relays) of the hard-wired electrical box are directly connected to the harness terminals or bus bars, and thus to the harness. The components and parts of the PCB type electrical box are connected with the terminals of the PCB firstly, and then are connected to the wiring harness connector through the PCB loop, so that the wiring harness is connected.
Generally, only one of the two structures is adopted in the design of the electric box in the engine compartment of the automobile, and the structure is either a hard-wire structure or a PCB structure.
The independent hard-wired electrical box is inconvenient to assemble, low in automation degree and inconvenient in wiring harness switching, but is easy to control the temperature rise of a heavy-current load, good in heat dissipation and relatively low in cost under the general condition. The independent PCB type electric appliance box has the advantages that for heavy current load, temperature rise is not easy to control, materials are relatively more, weight is large, cost is relatively higher, switching can be provided for wiring harnesses, and miniaturization design is facilitated.
Existing patent documents were retrieved:
1. a hybrid electrical box (CN 105228387A);
2. a center electrical box (CN109572599A) for an automobile;
3. a central electrical box (CN205231288U) adopting a tuning fork terminal design;
4. an automobile central electrical box (CN 302888317S);
5. a novel automobile central electric box device (CN 202282924U).
The technical solutions provided in the above patent documents were analyzed and learned that: if the engine compartment uses a hard-wired electrical box, in order to facilitate the assembly of the wiring harness, part of the functions are generally moved to the electrical box of the passenger compartment, and the functions are reduced. Meanwhile, in order to facilitate the wiring harness switching, a waterproof switching plug-in unit is generally added at the joint of an engine compartment wiring harness (a hard-wire type electrical box is attached to the wiring harness) and a passenger compartment wiring harness, but when the function is transferred to the passenger compartment electrical box, relay sound can occur in the passenger compartment, the length of the wiring harness of a part of load circuits can be increased, and the cost is increased. If the engine compartment uses the PCB type electrical box, the number of layers and thickness of the PCB board are generally increased in order to control the temperature rise of the electrical box, but this may result in an increase in the weight and cost of the electrical box.
