Abstract

The utility model discloses an inductor assembly structure, comprising an iron core base with an accommodating cavity, an iron core upper cover, a convex central pillar formed into a whole with the iron core base and a coil surrounding the central pillar. The iron core upper cover is tightly fit with the iron core base. The iron core base is provided with at least two grooves or convex bodies. The iron core upper cover is correspondingly provided with convex bodies or grooves. The convex bodies are accommodated in the grooves. In the process for assembling and forming the inductor, the convex bodies are aligned with the grooves to carry out assembly and then a clamp is used for clamping the inductor assembly structure to carry out roasting. As the convex bodies are limited in the grooves, position deviation can not occur between the iron core base and the iron core upper cover. Therefore, the utility model is convenient for processing forming, thereby having high product qualification ratio.

Embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

As Fig. 1～shown in Figure 4, a kind of inductive bank assembling structure 10 that the utility model provides comprises heel piece 11, iron core loam cake 12, center pillar 13 and coil 14, and inductance of the present utility model can be a chip inductor or plug-in unit inductance.Heel piece 11 has a containing cavity 15, and center pillar 13 is one-body molded with described heel piece, and raises up, and this center pillar 13 is the R rod.R rod 13 is fixedly arranged in the containing cavity 15, and is positioned at the center of containing cavity 15, and coil 14 is surrounded on the R rod 13, and heel piece 11 fits tightly with iron core loam cake 12.

Heel piece 11 is provided with four grooves 111, and iron core loam cake 12 is provided with and groove 111 corresponding convex bodys 121, and convex body 121 is contained in the groove 111.Obviously, for guaranteeing heel piece 11 and iron core loam cake 12 relative displacement does not take place, groove 111 and convex body 121 should be respectively provided to few two.Preferably, groove 111 is symmetricly set on the heel piece 11 about R rod 13.In the process of the utility model assembled formation, with the groove 111 on the 121 aligning heel pieces 11 of the convex body on the iron core loam cake 12, toast with the clip clamping then, because in the groove 111 that convex body 121 is restricted to, thereby can the occurrence positions skew between heel piece 11 and the iron core loam cake 12.Whereby, the utility model is convenient to machine-shaping, thereby has than high production yield.

Obviously, the groove 111 on the heel piece 11 can be convex body, and the convex body 121 on the iron core loam cake 12 then relative set is a groove.

The external diameter of convex body 121 is than the little 0.03mm～0.04mm of internal diameter of groove 111, so that assembling, convex body 121 can be cylinder, cone, Rotary-table or polygonal cylinder etc., preferably adopts Rotary-table in actual applications.Preferably, the height of described convex body 121 is 1/3rd of its external diameter.

As shown in Figure 3, containing cavity 15 has the gap 151,152 of two symmetries, and coil 14 has two terminals 141,142, and this coil terminals 141,142 is drawn out to outside the pedestal 11 by gap 151,152 respectively.Coil 14 preferred employing copper cash coilings form.

Also be provided with curing glue in the containing cavity 15.In the process of the utility model moulding, coil 14 is surrounded on the R rod 13, then two coil terminals 141,142 are drawn out to respectively outside the pedestal 11, again with the groove 111 on the 121 aligning heel pieces 11 of the convex body on the iron core loam cake 12, toast with the clip clamping then, curing glue melted by heat in the containing cavity 15 combines iron core loam cake 12 and heel piece 11 closely, and assembling is at last finished.

In sum, the utility model is by being provided with at least two grooves or convex body on the heel piece of inductive bank assembling structure, simultaneously in described iron core loam cake relative set in convex body or groove, in the process of inductance assembled formation, with the convex body that covers on the described iron core or groove or the convex body on the described heel piece of groove alignment, toast with this inductive bank assembling structure of clip clamping then, because the convex body of described iron core loam cake is restricted in the groove of described heel piece, or the convex body on the described heel piece is restricted in the groove of described iron core loam cake, making can the occurrence positions skew between described heel piece and the described iron core loam cake. whereby, the utility model is convenient to machine-shaping, thereby has than high production yield.

Certainly; the utility model also can have other various embodiments; under the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the utility model.
