Abstract
Provided is a chip inductor, comprising a base, a magnetic core disposed on the base, a plurality of conductive terminals inlaid in the base and a plurality of conductive coils winding the magnetic core. The magnetic core comprises an axle center and an outer frame accommodating the axle center. The axle center comprises a first flange part and a column-shaped part extending from the first flange part. The conductive coil winds the column-shaped part. The edge of the first flange is provided with a notch. The upper surface of the base is provided with a protruding part accommodated in the notch. With the above cooperation, the height is reduced and the axle center can be prevented from rotation when being disposed in the base.
Description
[technical field]
The utility model is about a kind of chip inductor, relates in particular to the holding structure of axle center and base portion.
[background technology]
The prior art relevant with invention, consulting publication number is the Japanese publication of JPA2008235459.This publication has disclosed a kind of chip inductor, and it comprises base portion, is installed on the magnetic core on the base portion, and said magnetic core comprises the axle center and accommodates the housing in axle center; Said axle center comprises first, second flange portion and connects the columnar part of first, second flange portion; The both sides of the said first flange portion bottom surface are provided with jut, and said base portion is provided with accepting hole in order to accommodating jut, yet; There is certain defective in such design, and first flange portion is provided with jut makes the height of whole chip inductor higher.
So, be necessary to design a kind of novel chip inductor to solve the problems of the technologies described above.
[utility model content]
The utility model technical problem to be solved provides the shorter chip inductor of a kind of height dimension.
For solving the problems of the technologies described above; The utility model provides a kind of chip inductor; It comprises base portion, is installed on the magnetic core of base portion, is embedded in plurality of conductive terminals and some conductive coils that is wound on the magnetic core in the base portion, and said magnetic core comprises the axle center and accommodate the housing in axle center that said axle center comprises that first flange portion reaches from the extended columnar part of first flange portion; Said conductive coil is wound in columnar part; The edge of said first flange portion is provided with breach, and the upper surface of said base portion is provided with jut, and said jut is contained in breach.
The jut that relative prior art, first flange portion of the utility model chip inductor in the axle center are provided with two breach and the base portion incompatible rotation that prevents the axle center that matches, thus such design makes the height of chip inductor shorter.

Fig. 2 is the three-dimensional view of another angle of chip inductor shown in Figure 1.
Fig. 3 is the base portion of chip inductor and the exploded view of magnetic core.
Fig. 4 is the explosive view of chip inductor.
Fig. 5 is the explosive view of another angle of chip inductor shown in Figure 4.
[embodiment]
To shown in Figure 5, meet a kind of chip inductor 100 of the utility model like Fig. 1, it comprises base portion 10, is installed on the magnetic core 20 of base portion 10, is embedded in plurality of conductive terminals 30 and some conductive coils 40 that is wound on the magnetic core 20 in the base portion 10.
Said magnetic core 20 comprises axle center 21 and accommodates the housing 22 in axle center 21; Said axle center 21 comprises first flange portion 210, from the center of first flange portion 210 the extended columnar part 211 and second flange portion 212 that links to each other with the other end of columnar part 211, said first flange portion 210 and second flange portion 212 are symmetrical set.Said axle center 21 integral body are cylindrical; The diameter of first, second flange portion 210,212 is greater than the diameter of columnar part 211; Therefore the edge of first, second flange portion 210,212 all extends the periphery of columnar part 211; Thereby form a receiving space 213, said conductive coil 40 is wound in columnar part 211 and is contained in receiving space 213.Said first flange portion 210 is extended columnar part 211 peripheral edges and is provided with two breach 214, and said breach 214 is symmetrical set with respect to columnar part 211, and said breach 214 is expanded to both sides more outward more.
Said base portion 10 is rectangles; Its upper surface is provided with in order to groove 11 of accommodating first flange portion 210 and the jut 12 that extends from the edge of groove 11 both sides; It is said when axle center 21 is installed in base portion 10; Jut 12 is contained in the breach 214 of first flange portion 210, thereby axle center 21 does not rotate.Said conducting terminal 30 comprises the contact site 31 that extends base portion, be retained on the holding parts 32 in the base portion 10 and expose the weld part 33 of the lower surface of base portion 10, and the said conductive coil 40 that is wound in magnetic core 20 comprises contact terminal 41.The contact of said conductive coil 40 terminal 41 is wound in the contact site 31 of conducting terminal 30 respectively, and contact terminal 41 electrically connects with contact site 31, when weld part 33 is welded on the circuit board, and conductive coil 40 and circuit board conducting.
Said housing 22 comprises the end face 220 of rectangle and the fixing arm 221 that extends from end face 220, and said end face 220 is provided with a circular hole 222 that runs through end face 220, and the inboard of said fixing arm 221 is that circular arc links to each other with the inboard of circular hole 222.When said housing 22 is installed on base portion 10; Axle center 21 is contained in the housing 22; The end face 220 of the upper surface of second flange portion 212 and housing 22 is on same plane, and said fixing arm 221 is contained in the groove 11 of base portion 10, and jut 12 is contained in respectively between the two fixing arms 221.
The incompatible rotation that prevents axle center 21 that matches of relative prior art, the utility model chip inductor 100 jut 12 that 21 first flange portion 210 is provided with two breach 214 and base portion 10 in the axle center, thus such design makes the height of chip inductor 100 shorter.
