Description
Technical field
The utility model relates to a kind of laminated inductance.
Background technology
Inductor is a kind of at the comparatively common electronic component of circuit, it mainly plays the effects such as filtering, vibration, delay, trap in circuit, screen in addition signal, filtered noise, stabling current and suppress the effects such as Electromagnetic Interference, therefore application comparatively extensively, but current inductor adopts winding structure more, adopt the inductance volume of this structure large, shield effectiveness is poor, welding trouble, and be not suitable for the paster operation of precision circuit.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provide a kind of volume little, be applicable to paster operation laminated inductance.
The utility model solves the technical scheme that its technical problem adopts:
A kind of laminated inductance, comprise inductance body, described inductance body is a cube structure, its middle part is a ferrite, and its two ends are provided with welding electrode, are provided with the annular conductive film of multilayer in this ferrite, and be provided with fracture on this annular conductive film, adjacent annular conductive film is end to end, makes the annular conductive film of multilayer be connected into the circuit structure of a coiling, is respectively arranged with the internal electrode being connected with two ends welding electrode on the annular conductive film of top and bottom.
Described ferrite is the multilayer laminated structure corresponding with annular conductive film.
The beneficial effects of the utility model are: a kind of laminated inductance, comprise inductance body, described inductance body is a cube structure, its two ends are provided with welding electrode, its middle part is a ferrite, in this ferrite, be provided with the annular conductive film of multilayer, and be provided with fracture on this annular conductive film, adjacent annular conductive film is end to end, make the annular conductive film of multilayer be connected into the circuit structure of a coiling, on the annular conductive film of top and bottom, be respectively arranged with the internal electrode being connected with two ends welding electrode, when energising, electric current forms inductive circuit by end to end annular conductive film coiling, realize the function of inductance, and by the airtight annular conductive film shielding of ferrite, make the utlity model has following advantage: size is little, be conducive to the miniaturization of circuit, be conducive to paster automated production, magnetic circuit closed, can not disturb components and parts around, also can not be closed on the interference of components and parts, be conducive to the high-density installation of components and parts, integral structure, reliability is high, thermal endurance, solderability are good, shape is regular, is suitable for automation surface production is installed, reduce costs.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is internal structure schematic diagram of the present utility model.
Embodiment
With reference to Fig. 1, Fig. 2, Fig. 1, Fig. 2 is the structural representation of a specific embodiment of the utility model, as shown in the figure, a kind of laminated inductance, comprise inductance body, described inductance body is a cube structure, its middle part is a ferrite 2, its two ends are provided with welding electrode 1, in this ferrite 2, be provided with the annular conductive film 3 of multilayer, and be provided with fracture on this annular conductive film 3, adjacent annular conductive film 3 is end to end, make the annular conductive film 3 of multilayer be connected into the circuit structure of a coiling, on the annular conductive film 3 of top and bottom, be respectively arranged with the internal electrode 4 being connected with two ends welding electrode 1, in the present embodiment, described ferrite 2 is the multilayer laminated structure corresponding with annular conductive film 3.
