Description
Technical field
The utility model is about the Wound-rotor type Inductive component, and especially in regard to the replaceable Wound-rotor type Inductive component of a kind of iron core, it can select suitable independent core body according to conditions such as the operating frequency of electronic building brick, power demands.
Background technology
The Wound-rotor type Inductive component is the electric current variation through coil, and to produce the variation of magnetic flux, it is a kind of of passive component, and is widely used in the electronic product.Existing Wound-rotor type Inductive component mainly comprises coil holder and iron core two parts; Open accompanying drawing like novel M264631 number " structure-improved of inductor core " patent case of the TaiWan, China Republic of China of Figure 1A; And the open accompanying drawing of novel M264632 number " structure-improved of inductor core and coil holder " patent case of TaiWan, China of Figure 1B, all comprising iron core 100 and coil holder 200, the central authorities of this iron core 100 are provided with a center pillar 110; Be respectively equipped with the lateral column 111 that protrudes to center direction in these center pillar 110 both sides; And the central authorities of coil holder 200 and be provided with an interstitial hole 220 then are wound with coil 222 in the outer peripheral edges of this interstitial hole 220, make two iron cores 100 embed the interstitial hole 220 of coil holder 200 respectively from the both sides of coil holder 200 with center pillar 110; Lateral column 111 with the both sides is coated on position, coil holder 200 both sides again, reaches the combination of iron core 100 and coil holder 200.
It is integrally formed that but above-mentioned iron core 100 is all, and after it was accomplished with die casting, the shape of center pillar 110 and volume can't change arbitrarily; And center pillar 110 is a same material with lateral column 111; So on the degree of freedom of material selection, also be restricted, the Inductive component of different capacity often needs the iron core of different size, material; The result that kind is many causes producing required mould and greatly increases.
The product (WaAc) that the coiling window ara of inductance and core section are long-pending is relevant with the ability of iron core processing power; This product is big more; The power that can handle is also big more, so existing inductor structure, except the shape volume of restriction center pillar; Also limit the size (coiling window ara) of coil holder, and then caused this inductor only can be applicable to power bracket specific and limited on the power supply product.
Shown in Fig. 1 C, after existing Inductive component makes up completion, (ascend the throne up and down between two iron cores 100) between its two center pillars 110 and form an air gap 300 for another example, this air gap 300 can be relative with the some that is wound in the coil in the iron core middle column 110.Make when Inductive component uses, often cause to produce bigger electric current, cause Inductive component that the phenomenon of heating is arranged at the coil of air gap 300 positions.And the air gaps 300 that are positioned at coil holder 200 central authorities can make magnetic line of force skew, and then influences in the winding wire electric current in same direction set, so conductor temperature is raised unavoidablely, and the useful life of shortening inductor.
When looking iron core and be a large tracts of land conductor, though its induced voltage is not high, the electric current that passes through is very big; When so the core configuration of above-mentioned inductor is the E type; On insulation processing, be difficult for coating fully, be easy to generate great circulation loss, when serious; The iron core local pyrexia is melted, and this is the big shortcoming on using.
The utility model content
Therefore; The purpose of the utility model provides the replaceable Wound-rotor type Inductive component of a kind of iron core; Its center pillar with iron core becomes independently core body; And all the other of iron core partly become independently housing, through changing the size and the material of core body and housing, can make the Inductive component of the utility model be applicable to the different capacity product.
The replaceable Wound-rotor type Inductive component of the iron core of the utility model; Comprise: a coil holder, be provided with a central tank, its outside is provided with coiling face can supply winding around; It is provided with the Plug Division in two ends up and down, and said coil can be communicated with power supply or other electric circuitry packages through said Plug Division; One columnar core is magnetic material, is located in the central tank of said coil holder; One housing is magnetic material, coats said coil holder and columnar core; It is characterized in that: said housing and core body are the separate type setting.
Preferably, when said core body is located at the central tank inside of coil holder, be formed with the inter-air space between the inner face of end face and housing about it.
Preferably, between the inner face of the end face up and down of said core body and housing with filler or fill out and establish pad and form the inter-air space.
Preferably, said housing is made up of two U type unit that respectively comprise base plate and biside plate relatively.
Preferably, the material of said housing and core body can constitute by being selected from MnZn system, Ni-Zn series or the Ferrite Material of magnesium zinc system or the alloy type material of silicon steel material, iron powder, sendust, iron-nickel alloy, iron nickel-molybdenum alloy, amorphous or microcrystallizing alloy.
Preferably, said housing and core body can be same material or different materials.
According to the replaceable Wound-rotor type Inductive component of the iron core of the utility model; Can increase housing, core body and the coil holder size combinations degree of freedom each other; For example; Coil holder coiling window ara can change along with the difference of core size, or the housing of fixed dimension can the arrange in pairs or groups multiple different core body and the size combinations of coil holder; Also increased housing, the degree of freedom of core body on material is selected, therefore, can select the material of housing and core body, and housing and core body can be different materials according to conditions such as magnetic material characteristic, operating frequencies.So can let the user after accomplishing circuit design, select suitable size combinations according to factors such as power demand, cost, permission loss, installing spaces, can also simplify production and improve yield, this is a purpose of the utility model.
According to the replaceable Wound-rotor type Inductive component of the iron core of the utility model, because center pillar becomes an independent core body, so the position of the utility model Inductive component air gap; Space between housing base plate and core body end face; Promptly be positioned at place, coil holder two ends, be positioned at the coil holder center than existing air gap, the air gap of the Inductive component of the utility model has heat-sinking capability preferably; Increase the useful life of Inductive component, this is another purpose of the utility model.
According to the replaceable Wound-rotor type Inductive component of the iron core of the utility model, housing is partly only possessed the lateral column on both sides, thus the housing insulation coat more easily, more complete, and then promote the degree of safety of using, this is the another purpose of the utility model.
As for detailed construction, application principle, effect and the effect of the utility model, the explanation of then doing with reference to following adjoint can be understood completely.
