Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with specific embodiment, and referring to the drawings, the utility model is described in further detail.
Referring to Fig. 1, Fig. 2 and Fig. 3, Fig. 1 shows three-dimensional exploded view when each composition component of this utility model chip inductor structure separates.Fig. 2 shows cup-shaped iron core axonometric chart in this utility model chip inductor structure.Fig. 3 shows the stereogram of bottom view of cap in this utility model chip inductor structure.As it can be seen, this utility model chip inductor structure 100 includes cup-shaped iron core 1, coil groups 2, cap 3.
Cup-shaped iron core 1 is made up of substrate 11, ring wall 12, open top 13 and a pair breach 14,15, and the periphery of substrate 11 upwards protrudes out formation ring wall 12 and forms open top 13 at ring wall 12 top, and the apical margin of ring wall 12 offers a pair breach 14,15.The center pillar 16 separately including a circular cylindrical shape is upwards protruded out by substrate 11 center position, defines a coil bearing space 17 between ring wall 12 and center pillar 16, and the top of center pillar 16 is formed with the recess 18 of a hexagonal configuration.
Coil groups 2 has a pair leading-out terminal 21,22, and connecting in the end of this leading-out terminal 21,22 has pair of conductive terminal 24,25.Coil groups 2 is placed in coil bearing space 17 by the open top 13 of cup-shaped iron core 1, and when coil groups 2 inserts coil bearing space 17, leading-out terminal 21,22 is respectively by the breach 14,15 of cup-shaped iron core 1.Conducting terminal 24,25 can just distinguish a pair breach 14,15 that corresponding bearing is formed at ring wall 12 top of substrate 11.Because leading-out terminal 21,22 and conducting terminal 24,25 are symmetrical with breach 14,15 Position Design, it is ensured that the location positioning of leading-out terminal 21,22 is the most accurate.
Cap 3 has end face 31 and a bottom surface 32, this bottom surface 32 blanketing is at the open top 13 of cup-shaped iron core 1, and the center position in cap 3 bottom surface 32 protrudes out and is formed with a positioning convex portion 33, this positioning convex portion 33 is designed to the recess 18 on corresponding center pillar 16 top, therefore the recess 18 on this center pillar 16 top becomes hexagonal design in this utility model most preferred embodiment as shown in the figure, therefore the positioning convex portion 33 that cap 3 bottom surface 32 protrudes out becomes hexagon, corresponding can combine in order to both and form locating effect.When reality is applied, also the structure of recess 18 with positioning convex portion 33 can be exchanged, still can reach locating effect.
Refer to Fig. 4, plan view from above when each composition component of its display this utility model chip inductor structure combines.As shown in the figure, when the cup-shaped iron core 1 of this utility model chip inductor structure 100, coil groups 2, cap 3 integrally combine, because of through the positioning convex portion 33 corresponded in the recess 18 designed by center pillar 16 top of cup-shaped iron core 1 and cap 3 designed by recess 18, cup-shaped iron core 1 and cap 3 can be made when combining to keep having a fixed range between the two, magnetic core can be made to be difficult to full cause Dc bias to reduce.
Refering to Fig. 5, polarity mark structural representation in its display this utility model chip inductor structure.As shown in the figure, the substrate 11 of cup-shaped iron core 1 is formed with polarity mark structure A, this polarity mark structure A can be concave point or the mark of any shape, and this polarity mark structure A is available for user and distinguishes rapidly and correctly polar orientation, uses definitely in order in polarity.
Above example is only the design of illustrative structure of the present utility model, not for limiting this utility model.Above-described embodiment all can be modified and change under structure of the present utility model design and spirit by any ripe personage in this skill, and only these changes still belong in spirit of the present utility model and claims.Rights protection scope the most of the present utility model should be as listed by claims.
