The utility model has the characteristics of the welding is convenient, good heat dissipation.
Description
Technical field
This utility model is related to technical field of electronic devices, especially relates to that a kind of to have convenient welding, thermal diffusivity good
FERRITE CORE inducer.
Background technology
Power inductance is always the important electronic building brick in board application field, its applied range and usage quantity is huge
Greatly, it is mainly used in noise suppressed, rectification, flat ripple etc..Because itself there is D.C. resistance, power inductance operationally can not
Disconnected heating, and generally due to can constantly carry out heat exchange with external environment condition, element itself will not suffer damage.But super
During load operation, the too high softening that may result in coil covering of heating temp and foaming, thus occur coil turn-to-turn short circuit existing
As causing power inductance short-circuit failure.In addition, power inductance needs to carry out wicking welding in production engineering, because wicking is deep
Spend the reasons such as depth, scaling powder immersion, weld interval long, welding times excessive (more than 2 times), be easy to lead to coil impaired
Short circuit, and these damage and are difficult to be screened out in production and test process, so that the reliability of power inductance is reduced.
Inducer is similar to that transformator, but only one of which winding.Inducer has certain inductance, and it only stops
The change of electric current.If not having electric current to pass through in inducer, it stops electric current from flowing through it；Flow through it if there are electric current, then electricity
When road disconnects, it will attempt to maintain electric current constant.The various coils of inducer insulated conductor coiling are referred to as inductance.With wire around
Become a circle or multiturn to produce the electronic component of certain self-inductance, often claim inductance coil or abbreviation coil.Inducer is in electric wire
It is widely used in road, for one of realization vibration, tuning, coupling, filtering, delay, the main element of deflection.In order to increase inductance
Measure, improve Q-value and reduce volume, in coil, often insert magnetic core.
FERRITE CORE inducer is with FERRITE CORE as support, forms a coiling line by the coiling of enamel-covered wire
Circle, and draw two terminations before and after enamel-covered wire coiling, the one kind forming as the positive and negative electrode of inducer is in circuit electricity
The energy-storage travelling wave tube that magnetic energy can be converted into and store.
Content of the invention
Goal of the invention of the present utility model is to overcome inducer heating of the prior art and welding process inconvenience
Not enough, there is provided a kind of have the good FERRITE CORE inducer of convenient welding, thermal diffusivity.
To achieve these goals, this utility model employs the following technical solutions：
A kind of FERRITE CORE inducer, including FERRITE CORE, is wound on the coiling group in FERRITE CORE, located at ferrum oxygen
2 pins being connected with coiling group termination of body magnetic core one end, located at fin and the parcel ferrum oxygen of the FERRITE CORE other end
The encapsulation bed of material of body magnetic core and coiling group；Described pin is provided with cavity near one end of FERRITE CORE, is provided with described cavity
Solder(ing) paste.
This utility model is provided with the cavity of filling solder(ing) paste in inducer pin near one section of FERRITE CORE, using electricity
During sensor, directly with welding gun, cavity can be welded leakage, so that solder(ing) paste is reserved, convenient welding；Increase in one end of inducer simultaneously
Fin, prevents the inducer from damaging because temperature is too high.
Preferably, the section of described FERRITE CORE is in I shape.
Preferably, described encapsulating compound is epoxy resin.
Therefore, this utility model has the advantages that：Convenient welding, thermal diffusivity are good.
Brief description
Fig. 1 is a kind of structural representation of the present utility model.
In figure：FERRITE CORE 1, coiling group 2, pin 3, fin 4, the encapsulation bed of material 5, cavity 6.
Specific embodiment
With reference to the accompanying drawings and detailed description this utility model is further described.
Embodiment as Fig. 1 is a kind of FERRITE CORE inducer, including FERRITE CORE 1, is wound in FERRITE CORE
Coiling group 2,2 pins 3 being connected with coiling group termination located at FERRITE CORE one end, located at the FERRITE CORE other end
Fin 4 and parcel FERRITE CORE and coiling group the encapsulation bed of material 5；Described pin is provided near one end of FERRITE CORE
Cavity 6, is provided with solder(ing) paste in described cavity；The section of described FERRITE CORE is in I shape；Described encapsulating compound is epoxy resin.
This utility model is provided with the cavity of filling solder(ing) paste in inducer pin near one section of FERRITE CORE, using electricity
During sensor, directly with welding gun, cavity can be welded leakage, so that solder(ing) paste is reserved, convenient welding；Increase in one end of inducer simultaneously
Fin, prevents the inducer from damaging because temperature is too high；Using vacuum negative pressure type, controlled by infrared light technology, epoxy resin is sealed
It is attached to outside FERRITE CORE and coiling group.
Therefore, this utility model has the characteristics that convenient welding, thermal diffusivity are good.
It should be understood that the present embodiment is merely to illustrate this utility model rather than limits scope of the present utility model.In addition
It should be understood that after having read the content of this utility model instruction, those skilled in the art can make various to this utility model
Change or change, these equivalent form of values equally fall within the application appended claims limited range.
