Abstract
The utility model discloses a printed circuit board used for replacing a coil of a transformer. The printed circuit board includes copper-clad plates and an insulating pad. A spiral circuit is printed on a copper foil surface at one face of the copper-clad plates; there are at least two copper-clad plates; and the insulating pad is arranged between two adjacent copper-clad plates. According to the printed circuit board of the utility model, the spiral circuit is printed on the copper foil surface at one face of the copper-clad plates so as to form a primary coil or a secondary coil of the transformer, thereby greatly reducing the consumption of enameled wires and copper foil wires of a transformer coil in the prior art and decreasing production cost; the insulating pad is arranged between the two adjacent copper-clad plates, thereby facilitating ventilation and heat dissipation for the transformer.
Description
Technical field
The utility model relates to a kind of printed circuit board, is specifically related to a kind of printed circuit board for the instead of transformers coil.
Background technology
Transformer is a kind of static electrical equipment.Utilize electromagnetic induction principle at two or more between the multi-coil, convert a kind of voltage and current of grade to the voltage and current of the another kind of grade of same frequency and electric energy transmitting.Coil is the basic element of character of transformer voltage of transformation, and coil is comprised of the different numbers of turn, because the one turn voltage of different coils is the same, therefore need to realize different voltage by the coil of the different numbers of turn.Existing transformer coil has plenty of with the enamelled wire coiling and forms, and has plenty of to form with Copper Foil or aluminium foil coiling.All have common defective with enamelled wire or the coiling of copper aluminium foil, radiating effect is bad, usually causes transformer to damage because the transformer radiating effect is relatively poor.Secondly because the transformer model is various, need the enamelled wire of the various wire diameters of deposit or the copper aluminum foil plate of different model, manufacturing process is comparatively loaded down with trivial details.
The utility model content
The utility model is for a kind of printed circuit board for the instead of transformers coil of above-mentioned not enough design, purpose is: replace existing transformer coil by the utility model, make transformer have good heat dispersion, reduce the cost of manufacture of transformer, the utility model is simple in structure, and is easy to make.
Technical solution of the present utility model:
A kind of printed circuit board for the instead of transformers coil comprises copper-clad plate and insulation cushion, it is characterized in that: the copper foil surface of described copper-clad plate one side is printed with spiral helicine circuit, and copper-clad plate is at least two, between adjacent two copper-clad plates insulation cushion is installed.
Pass through the fastening location of pin between the described copper-clad plate.
The circuit on described each sheet copper-clad plate surface is connected mutually.
The beneficial effects of the utility model:
By printing primary coil or the secondary coil that spiral helicine circuit forms transformer at the copper foil surface of copper-clad plate one side, can greatly reduce the use amount of existing transformer coil enamelled wire and Copper Foil line, reduce cost of manufacture, the utility model is the installing insulating pad between adjacent two copper-clad plates, is conducive to the transformer ventilation and heat.
Description of drawings
The utility model will be further described below in conjunction with the drawings and specific embodiments.
Fig. 1 is front view of the present utility model.
Fig. 2 is side diagram of the present utility model.
Wherein: 1, copper-clad plate; 2, spiral helicine circuit; 3, insulation cushion.
Embodiment
Extremely shown in Figure 2 such as Fig. 1, a kind of printed circuit board for the instead of transformers coil, comprise copper-clad plate 1 and insulation cushion 3, the copper foil surface of described copper-clad plate 1 one side is printed with spiral helicine circuit 2, copper-clad plate 1 is at least two, between adjacent two copper-clad plates 1 insulation cushion 3 is installed, by the fastening location of pin, the circuit on described each sheet copper-clad plate 1 surface is connected mutually between the copper-clad plate 1.
