Description

A kind of bottom plate inductance

Technical field

The utility model relates to inductive technologies fields, more specifically, the utility model relates to a kind of bottom plate inductance.

Background technique

Inductor is that conducting wire is wound and a kind of manufactured energy storage electronic component on FERRITE CORE.Ring-shaped inductors are a kind of Common inductor structure, using annular ferrite core as matrix winds insulated conductor and is made.Ring-shaped inductors are mainly used in In the circuits such as Switching Power Supply, communication, filtering.The production technology of existing ring-shaped inductors, insulated conductor usually extended and plated Connector of the tin as connection line plate.When the insulated conductor line footpath used is too small, meeting hardly possible due to connecting wire is excessively soft To be inserted into wiring board, the efficiency of installation is influenced.

In addition, the inductance of FERRITE CORE production, magnetic core select the non-circular shapes such as EE type, PQ type in the prior art, this Class formation cause along entire magnetic circuit direction core cross section product different and magnetic flux density it is different, while insulate and safety requirement all It will cause inductance higher cost and loss be larger and weak to ac and dc current anti-saturation ability.

Utility model content

For overcome the deficiencies in the prior art, the utility model provides a kind of bottom plate inductance, overcomes existing ring-shaped inductors It is difficult to the deficiency of plate, solves that existing inductor loss is big, the weak technical problem of anti-saturation ability.

The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of bottom plate inductance, improvements exist In: including toroidal core, coil and pedestal, the coil is wrapped on toroidal core, the toroidal core and coil shape The top of pedestal is set at assembly, and the lower surface of the pedestal is vertically connected with metallic pin, and the top of metallic pin It is connected with the conducting wire of coil；

The toroidal core includes magnetizer and non-magnetizer, and the width of the non-magnetizer is the toroidal core The 5%-10% of perimeter.

In such a configuration, the width of the non-magnetizer is the 6% of the toroidal core perimeter.

In such a configuration, an insulating layer is additionally provided between the toroidal core and coil.

In such a configuration, the insulating layer is by the epoxy resin figure layer of internal layer and the insulating bag covering layer structure of outer layer At.

In such a configuration, the non-magnetizer is located between two strands of conducting wires of coil.

In such a configuration, the material of the pedestal is insulating materials.

In such a configuration, the pedestal is rounded, and one of metallic pin is fixed on the circle of base lower surface At the heart.

The beneficial effects of the utility model are: using the soft conducting wire of hard metallic pin substitution as the company of ring-shaped inductors Junctor has the advantages that accurate positioning, installs convenient for plate, improves installation effectiveness；In addition, being located at the center point of base lower surface Metallic pin, play the role of angle, so that installation is very convenient quick, avoid occurring misplacing at pin or curved It is bent.

Specific embodiment

The present invention will be further described with reference to the accompanying drawings and examples.

It is carried out below with reference to technical effect of the embodiment and attached drawing to the design of the utility model, specific structure and generation It clearly and completely describes, to be completely understood by the purpose of this utility model, feature and effect.Obviously, described embodiment It is a part of the embodiment of the utility model, rather than whole embodiments, it is based on the embodiments of the present invention, the skill of this field Art personnel other embodiments obtained without creative efforts belong to the model of the utility model protection It encloses.In addition, all connection/connection relationships being related in patent, not singly refer to that component directly connects, and referring to can be according to specific Performance, by adding or reducing couple auxiliary, Lai Zucheng more preferably coupling structure.Each skill in the utility model creation Art feature, can be with combination of interactions under the premise of not conflicting conflict.

Referring to Fig.1, shown in Fig. 2 and Fig. 3, the utility model discloses a kind of bottom plate inductance, specifically, including annular magnetic Core 10, coil 20 and pedestal 30, the coil 20 are wrapped on toroidal core 10,20 shape of the toroidal core 10 and coil The top of pedestal 30 is set at assembly, and the lower surface of the pedestal 30 is vertically connected with metallic pin 40, and metallic pin 40 top is connected with the conducting wire of coil 20；In the present embodiment, the material of the pedestal 30 is insulating materials, the ring Be additionally provided with an insulating layer between shape magnetic core 10 and coil 20, and insulating layer by internal layer epoxy resin figure layer and outer layer it is exhausted Edge wrapping layer is constituted；The pedestal 30 is rounded, and one of metallic pin 40 is fixed on the center point of 30 lower surface of pedestal.

By this structure, soft conducting wire is substituted as the connector of ring-shaped inductors, tool using hard metallic pin 40 There is the advantages of accurate positioning, install convenient for plate, improves installation effectiveness；In addition, being located at the gold of the center point of 30 lower surface of pedestal Belong to guide pin 40, play the role of angle, so that installation is very convenient quick, avoids occurring misplacing at pin or being bent.

In the above-described embodiment, as shown in figure 3, the toroidal core 10 includes magnetizer 101 and non-magnetizer 102, and the width of the non-magnetizer 102 is the 5%-10% of 10 perimeter of toroidal core, it is preferable that non-magnetizer 102 Width be 10 perimeter of toroidal core 6%, also, the non-magnetizer 102 be located at coil 20 two strands of conducting wires it Between.It in the present embodiment, is filled in by non-magnetizer 102 in the gap of toroidal core 10, forms closed annular with magnetizer 101 Magnetic circuit；Magnetizer 101 is preferably ferrite, since ferrite high-frequency loss is low, and magnetic core along entire magnetic circuit sectional area consistent, magnetic Flux density is consistent, and irredundant core portion finally makes inductor loss low.In the effective magnetic conductance that ensure that 102 magnet ring of non-magnetizer Rate, while having good inductance anti-saturation ability again；Specifically, the preferred FR4 plate of the material of non-magnetizer 102, GPO-3 plate Or PPS plate.

It is to be illustrated to the preferable implementation of the utility model, but the utility model creation is not limited to institute above Embodiment is stated, those skilled in the art can also make various be equal without departing from the spirit of the present invention Deformation or replacement, these equivalent deformations or replacement are all included in the scope defined by the claims of the present application.
