Description
Technical field
It the utility model is related to the structure improved technology of inductor component, it is especially improved suitable for thin line inductors
Pre-install stitch bottom plate.
Background technology
Inductor is the element that electric energy can be converted into magnetic energy and stored.The structure of inductor is similar to transformation
Device, but an only winding.Inductor has certain inductance, it only hinders the change of electric current.If inductor is in no electricity
In the state of stream passes through, it will attempt to hinder electric current to flow through it when circuit is connected；If inductor is in the state for having electric current to pass through
Under, it will attempt to maintain electric current constant when circuit disconnects.Inductor is also known as choke, reactor, dynamic reactor.Inductor one
As be made of skeleton, winding, shielding case, encapsulating material, magnetic core or iron core etc..
Inductance is the string formation turned to enameled wire, cotton-covered wire or modeling rubber-insulated wire etc. in insulation framework or magnetic core, iron core
The coaxial wire turn of connection, it is represented with alphabetical " L " in circuit, main function be AC signal is carried out Isolation or with electricity
Container, resistor etc. form resonance circuit.
Inductance has many kinds, is made mostly with outer layer enamel coil encircling ferrite spool, and some protection inductance are line
Circle is completely disposed in ferrite.The core of some inductance elements can be adjusted.It is possible thereby to change inductance size.Small inductor can be directly
It is etched on pcb board, with a kind of method for being laid with helical trajectory.Small value inductance also can be used to the same technique system of manufacture transistor
Make in integrated circuits.In such applications, aluminum interconnecting is often used as conductive material.Which kind of ineffective method, based on reality
The still one kind of the constraint application on border at most is called the circuit of " gyrator ", it is shown and electricity with a capacitance and active member
The identical characteristic of sensing unit.Formed for the inductance element every high frequency through common one through the wire of magnetic pole or magnetic bead.
Some such as inductors with colour codes, colour loop inductance device play the sealings such as coil and magnetic core after making, with encapsulating material
Come.Encapsulating material is using plastics or epoxy resin etc..
Inductor influence factor includes：
(1), the number of turn：The number of turns of knee envelope curve, the number of turns is more, and inductance value is bigger.
(2), cross-sectional area：The thickness of knee envelope curve, thicker inductance value are bigger.
(3), there is centreless.
Inductance class component, its iron core, easily because temperature rise effect produces sensitivity changes, should be noted that its body temperature must with coiling
Must be using in specification limit.The coiling of inductor, electromagnetic field is easily formed in electric current by rear.When position of components is put,
Should be noted makes adjacent inductor away from each other, or coiling group is mutually at a right angle, to reduce mutual sensing amount.Inductor is each
Layer winding department, especially multi-turn filament, can also produce gap capacitance amount, cause high-frequency signal to bypass, and it is actual to reduce inductor
Filter effect.During with Meter Test inductance value and Q values, to ask data correct, test lead should try one's best close to component body.
The skeleton and connecting pin of existing inductor are embedded mostly, its connecting pin easily loosens, and most inductance
Only open two fairleads on skeleton to be used to connect lead circle, this structure wiring is inconvenient.
Utility model content
The purpose of this utility model is to provide the improved prepackage stitch bottom plate suitable for thin line inductors, thin easy to coiling line
Inductor product.
The purpose of this utility model will be realized by following technical measures：Including bottom plate, PIN needle, guide-localization side groove
And location hole；Bottom edge is provided with guide-localization side groove, vertical on a side on bottom plate to be fixedly mounted at least one group two
A PIN needle, meanwhile, location hole is provided with bottom plate.
Especially, bottom plate is the glass mat of rectangle.
Especially, the same lateral edges of bottom plate are provided with two guide-localization side grooves.
Especially, the opposite dual side-edge edge of bottom plate has two guide-localization side grooves.
Especially, on bottom edge fixed PIN needle is corresponded to close to guide-localization side groove location.
Especially, location hole, which is opened on bottom plate, fixes by PIN needle position.
The advantages of the utility model and effect：Install PIN needle in advance on bottom plate, and convinced by patient analysis on correspondence position edge
To positioning side groove, it is more convenient than conventional bottom plate perforation means, is especially beneficial the thin inductor product of coiling line.Coil tie lines jail
Gu broken string is few, coil end is wireless tail, without manually cutting, the qualification rate of product is high.Shorten the speed of assembled formation, manufacture
Cost is greatly reduced, and pin connection is firm, does not loosen, is effectively increased the service life of inductance；Package casing can be made to fix more
Fastening, and raw material utilization rate is reduced, and then reduce production cost.
Brief description of the drawings
Fig. 1 is 1 main structure diagram of the utility model embodiment.
Fig. 2 is 1 present invention looks up structural representation of the utility model embodiment.
Reference numeral includes：
Bottom plate 1, PIN needle 2, guide-localization side groove 3, location hole 4.
Embodiment
The utility model principle is that the inductance coil coiling later stage, which needs to pass through terminal pin, opens in the string holes on bottom plate,
Then stitch is arranged again and is finally connected fixation with the PIN needle of subsequent installation in product encapsulation；For nonstandard small lot or
