Description

A kind of novel chip inductor

Technical field

The utility model relates to a kind of inductance, more particularly, relates in particular to a kind of novel chip inductor.

Background technology

Existing SMD class inductance is generally E/I type bulk-breaking composite type, and because of the restriction of molding structure, powder die-casting moulding and coil groups are equipped with certain shortcoming, because the powder material is limited, can't have more high-end powder material to use to promote performance; E sheet (coverboard) is gone up the I sheet (magnetic core) that mainly plays the effect of inductance characteristic, and I sheet and whole E sheet are one, can't change material separately and promote inductance performance; The assembling of E sheet and I sheet is prone to dislocation and causes characteristic not enough, needs some glue with fixedly E sheet, I sheet, coil in the manufacturing process, and through baking so that glue is dried; Fixedly E sheet and I sheet harden until glue need to use clip in its process; But because of glue has swelling, be prone to cause air gap, reduced the sense value; There are shortcomings such as intensity is weak, production process is more, built-up time is long in E/I type inductance overall structure; Therefore, how to address the above problem, become problem demanding prompt solution.

The utility model content

The purpose of the utility model is the deficiency to above-mentioned prior art, and a kind of simple in structure, easy to process and a kind of novel chip inductor that inductance characteristic is strong is provided.

The technical scheme of the utility model is achieved in that a kind of novel chip inductor; It comprises housing, magnetic post core and coil; Housing is provided with interior ghost chamber; Coil encircling magnetic post core makes up in the shell chamber that is arranged at housing and injecting glue is fixed as one, and wherein the coil two ends form out the face that line segment is positioned at housing.

Above-mentioned novel chip inductor, the interior ghost chamber of said housing is square through passage, its height adapts with magnetic post core height, width and coil outer diameter adapt.

Above-mentioned novel chip inductor saidly goes out line segment and forms relative bayonet socket, with the case panel buckle at two ends, interior ghost chamber.

After the utility model adopts said structure,, can directly be arranged at the combination of coil encircling magnetic post core wherein through ghost chamber in forming housing; Internally ghost chamber and coil carry out a glue encapsulation with magnetic post core then, and realization ease of assembly and do not need clip to fix only need toast oven dry is got final product; Do not assemble the air gap phenomenon that is caused, inductance characteristic can be not influenced yet, the phenomenon that in the process of assembling, can not occur misplacing yet; It is simple to have reached assembling, the few and characteristic of simple of manufacturing procedure.Wherein the magnetic post core of independent processing and shell structure guarantee inductance characteristic, and can require to carry out more diversification processing of inductance characteristic according to different designs, have the wider characteristics of range of application.Go out the location positioning accurate technique effect that facial buckle syndeton that line segment forms symmetrical bayonet socket and housing guarantees out line segment.

The utility model compared with prior art has: 1, its U/R type magnetic structure design realization is identical with the E/I type, realizes satisfying the SMD class scope that is applied to; 2, the powder material is not limited, and inductance characteristic more diversification and range of application is wider; 3, traditional E/I type induction structure is stronger for its U/R type induction structure strength ratio, and the glue of fixation does not influence sense value characteristic because of glue sclerosis expansion increases internal air gap; 3, assembling procedure is simple, does not need to do until glue so that clip is fixing, can carry out operation to the tram according to the two end terminals location, so the variation that do not produced because of personnel's operation of the assembling flow path characteristic issues of deriving.

Embodiment

Consult shown in Fig. 1～5; A kind of novel chip inductor of the utility model; Comprise housing 1, magnetic post core 2 and coil 3; Housing 1 is provided with interior ghost chamber, and coil 3 makes up in the shell chamber that is arranged at housing 1 around magnetic post core 2 and injecting glue is fixed as one, and wherein coil 3 two ends form out the face that

line segment

31,32 is positioned at housing 1;

The interior ghost chamber of housing 1 is square through passage, and its height highly adapts with magnetic post core 2, width and coil 3 external diameters adapt;

Go out the bayonet socket that

line segment

31,32 forms phase, with housing 1 panel fastener at two ends, interior ghost chamber.

The utility model is when concrete the use; Through ghost chamber 11 in housing 1 forms; Can directly be arranged at coil 3 wherein around 2 combinations of magnetic post core; Internally ghost chamber 11 and coil 3 carry out a glue encapsulation with magnetic post core 2 then, realize ease of assembly and do not need clip to fix, and only need toast oven dry is got final product.In sum, the utility model is processed actual sample and through repeatedly use test, is seen that from the effect of use test provable the utility model can reach the purpose that it is expected like specification and diagramatic content, and practical value is unquestionable.The above embodiment that lifts only is used for conveniently illustrating the utility model; Be not that the utility model is done any pro forma restriction; Have common knowledge the knowledgeable in the technical field under any,, utilize technology contents that the utility model discloses to do the local equivalent embodiment that changes or modify if in the scope that does not break away from technical characterictic that the utility model is carried; And do not break away from the technical characterictic content of the utility model, all still belong in the scope of the utility model technical characterictic.
