Abstract
A circuit board structure of a car electrical appliance box comprises an upper circuit board, a lower circuit board, a power source input end, fuses and a standard plug, wherein the power source input end is arranged on the upper circuit board, and the standard plug is arranged on the lower circuit board. Each fuse is provided with a short plug and a long plug in a matched manner, the short plug is electrically connected with the power source input end, the upper circuit board is electrically connected with the lower circuit board via the long plug, and the long plug is welded onto the lower circuit board after penetrating through a through hole of the upper circuit board. The upper circuit board and the lower circuit board are directly connected by the fuse provided with the long plug, so that loop is shortened, loop resistance is reduced, hidden troubles of burning the electrical appliance box and cars are eliminated, welding supporting posts connecting loops of the upper circuit board and the lower circuit board are omitted, manufacturing cost is reduced, welding and assembling technology is simplified and production efficiency is improved. Besides, integral performance of the car electrical appliance box is improved.
Description
Technical field
The utility model relates to the automotive electronics device, and particularly the car insurance box specifically is a kind of circuit board structure of automobile electrical equipment box.
Background technology
In whole automotive electrical system, automobile electrical equipment box is very important critical component, and it is responsible for controlling the size of the electric current of each load to each load allocating power supply, is ensureing the security of operation of each load.
Along with developing of automobile industry, automobile superior, hommization, multifunction, the requirement of aspect such as high security and environmental protection is more and more higher, and the automotive interior load is also more and more, so the power consumption of car load electrical system is increasing, cause the caloric value of automobile electrical equipment box more and more higher, burn the electrical equipment box even burn the risk of automobile very big.
Wiring board is one of most important parts in the automobile electrical equipment box, is the soul place of automobile electrical equipment box.The reasonable structure in loop in the wiring board has embodied designer's level, has also determined the performance of wiring board simultaneously.At present, the design in wiring board loop is that electric current enters the upper layer circuit plate from power input, a short plug through the upper layer circuit plate enters the short plug of another one by insurance, enters lower floor's wiring board from the upper layer circuit plate through the welding support column then, exports from standard plug at last.The loop that electric current passes through in the electrical equipment box is long, and loop resistance is bigger, and voltage drop is bigger, causes the loop caloric value bigger, and temperature rise value is than higher, and the risk of burning electrical equipment box and vehicle is very high.
Summary of the invention
The purpose of this utility model is to provide a kind of circuit board structure of automobile electrical equipment box, it is longer that the circuit board structure of described this automobile electrical equipment box will solve in the prior art current circuit, cause big, the temperature rise of loop resistance, the technical problem of burning the electrical equipment box easily.
The purpose of this utility model is achieved through the following technical solutions: it comprises upper layer circuit plate, lower floor's wiring board, be located at power input and insurance on the upper layer circuit plate, be located at the standard plug on lower floor's wiring board, an insurance short plug of coupling and a long plug, this weak point plug and power input are electrically connected, and the upper layer circuit plate is electrically connected by this long plug and lower floor's wiring board.
Long plug passes from the via hole of upper layer circuit plate and is welded on lower floor's wiring board.
The utility model is compared with prior art, and its effect is actively with tangible.The utility model adopts the insurance of a long plug of coupling directly upper and lower two-layer wiring board to be connected in the circuit board structure of automobile electrical equipment box, not only shortened the loop, reduced loop resistance, eliminated and burnt the electrical equipment box and vehicle gets hidden danger, and saved the welding support column that connects levels wiring board loop, reduce production cost, simplified welding and assembling technics, improved production efficiency.The overall performance of electrical equipment box is improved.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
Embodiment
The utility model is described in further detail by embodiment below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, the circuit board structure of automobile electrical equipment box of the present utility model, it comprises upper layer circuit plate 2, lower floor's wiring board 6, is located at the power input 1 on the upper layer circuit plate and insures 4, is located at the standard plug 7 on lower floor's wiring board, insurance 4 a short plug 3 of coupling and long plugs 5, this weak point plug 3 is electrically connected with power input 1, and upper layer circuit plate 2 is electrically connected with lower floor's wiring board 6 by this long plug 5.Long plug 5 passes from the via hole 8 of upper layer circuit plate 2 and is welded on lower floor's wiring board 6.
During concrete enforcement, at first distribute drawing to carry out the design of wiring board integral layout according to load power source, all large current loads that work long hours and there is not the loop of relay to concentrate in together, be arranged in upper layer circuit plate 2 near near the power input 1, design each bar loop then as requested.A short plug 3 that connects insurance 4 is welded on upper layer circuit plate 2, the long plug 5 of another one directly is welded on lower floor's wiring board 6 by the via hole 8 of upper layer circuit plate 2, avoided loop current could arrive lower floor's wiring board 6 through the welding support column like this, electric current is through standard plug 7 outputs of lower floor's wiring board 6 then.
Certainly, also can be provided with one and allow bit architecture on the upper layer circuit plate, long plug can allow bit architecture pass from this.
Claims (2)
1. the circuit board structure of an automobile electrical equipment box, it comprises upper layer circuit plate, lower floor's wiring board, be located at power input and insurance on the upper layer circuit plate, be located at the standard plug on lower floor's wiring board, it is characterized in that: an insurance short plug of coupling and a long plug, this weak point plug and power input are electrically connected, and the upper layer circuit plate is electrically connected by this long plug and lower floor's wiring board.
