Chinese Patent Application No.: CN201120154068.7, a kind of Novel chip inductor is disclosed, belong to Novel chip inductor technical field, its technical essential comprises housing, magnetic post core and coil, housing is provided with interior ghost chamber, coil encircling magnetic post core combines in the shell chamber that is arranged at housing and injecting glue is fixed as one, and its coil two ends form the face that line segment is positioned at housing.

Above-mentioned utility model is created the welding that is unfavorable for enamelled wire, coil and magnetic core, and useful life is short, and inductance weak strength is not had stability.

Utility model content

The purpose of this utility model is, overcomes the above-mentioned defect of prior art, provides a kind of rational in infrastructure, and inductance value is stable, the open-flux path chip inductor of strong adhesion between element.

For achieving the above object, the technical scheme that the utility model provides is as follows: a kind of open-flux path chip inductor, comprise a bronze medal guide card, copper guide card comprises substrate and subtegulum, upper substrate and subtegulum are connected to a magnetic core bottom surface, the equal semicircular in shape of upper substrate and subtegulum, the convex sidewall that is provided with of circular arc, sidewall middle part is provided with hanging wire and hooks, and hanging wire hooks by the guide card punching press that makes progress and bends out hook body and form.

It is cylindric that magnetic core is " work " word, and magnetic core middle part has ring-like groove, and magnetic core top, magnetic core bottom are respectively upper stop piece, lower stop piece, and magnetic core middle part is roll.

Upper stop piece, lower stop piece edge have location notch, and hanging wire hooks inner side and is fastened on location notch.

Usefulness of the present utility model is: by hanging wire hook joint, pedestal, realizes coiling, and scolding tin, some glue, assembling, reprocessing lettering, test or packing, be mainly for coiling and scolding tin, assembling, realizes full automation.

1, copper guide card adopts one-side electroplating, strengthens the adhesive force of copper guide card and magnetic core, avoids the bad problem of adhesive force of the traditional surperficial tin of copper guide card and glue;

2, on copper guide card, design is hung around hook, realizes coiling full-automatic, greatly reduces cost of labor; Soldering tin technique in the design's finished product making, can realize complete unmanned operation automation;

3, use copper guide card to replace traditional end silver, be greatly better than traditional end silver products with the welding flatness of PCB;

4, the then mode of copper guide card and copper circle line is various, can the immersed solder of tin stove, and laser spot welding, high voltage butt-joint etc.;

5, magnetic core can be arranged to round, square, racetrack, can be used according to varying environment.
