Abstract
The invention relates to a straight-plug terminal applicable to an aluminum-base circuit board. The straight-plug terminal comprises an insulation support, a metal pin and a pin of the part of the metal pin exposed out of the insulation support. The root of the pin of the straight-plug terminal body is provided with an insulation sleeve close to the insulation support. Accordingly, the pin and a metal substrate of the aluminum-base circuit board can be isolated by the insulation sleeve. The insulation sleeve can be integrally formed with the insulation support and surrounds the protection wall around the root of the pin. The integrally formed insulation sleeve is simple in structure, convenient to manufacture and accurate. The insulation sleeve can be an independent insulation casing. The insulation sleeve can be realized by directly sleeving insulation tubing on the pin of an existing straight-plug terminal. The straight-plug terminal applicable to the aluminum-base circuit board is simple in structure, low in manufacturing cost and easy to realize, and the aluminum-base circuit board is more convenient in circuit design and wider in application.
Description
Technical field
The present invention relates to field of electronic circuitry, particularly relate to the direct insertion terminal being adapted to aluminum base circuit board.
Background technology
With the develop rapidly making electronic technology, aluminum base circuit board extensive use in electronic circuit.The advantage of aluminum base circuit board is specially: good heat dissipation effect and good mechanical performance, very effectively process thermal diffusion in circuit design, reduces product operating temperature, improves product power density and reliability, extends product useful life.
But, due to the reasons in structure of aluminum base circuit board, be usually only suitable for surface mount SMT technique, the terminals of connecting wire that aluminum base circuit board is installed generally also adopts surface-mount type splicing ear, so, there is following defect in the application: one is that mounted splicing ear cost is higher than direct insertion terminal; Two is because SMD splicing ear can only be installed on the cabling face (copper-clad surface) of aluminum base circuit board, is restricted when circuit design; Range of application equally for aluminum base circuit board is also restricted.
Summary of the invention
For overcoming above-mentioned technological deficiency, the technical problem to be solved in the present invention provides a kind of portable construction, easily making, the easy for installation direct insertion terminal being applicable to aluminum base circuit board.
The present invention solves a kind of direct insertion terminal being applicable to aluminum base circuit board of above-mentioned technological deficiency, as aluminum base circuit board, is made up of copper foil circuit layer, thermally conductive insulating layer, metal substrate; This aluminum base circuit board is also provided with the pad on the stitch hole and copper foil circuit layer that coordinate with the stitch of direct insertion terminal.The direct insertion terminal body being applicable to aluminum base circuit board comprises: insulating support, metal ferrule and this metal ferrule are exposed to the stitch of insulating support part.One section of insulating case is provided with near insulating support position at the stitch root of direct insertion terminal body.This direct insertion terminal body is arranged on the face of the metal substrate of aluminum base circuit board, stitch is through the stitch hole of aluminum base circuit board, the stitch that stitch is exposed to insulating case part is connected with pad soldering, like this, just isolates by insulating case between stitch and the metal substrate of aluminum base circuit board.
Described insulating case can be a kind of and described insulating support integrated, be enclosed in retaining wall around stitch root.Adopt this integrated insulating case, structure is simple, easily manufactured, precision is accurate.
Described insulating case can also be one independently insulating sleeve.This scheme, although not too convenient at manufacture view, directly can be set with insulated pipes used and realize on the stitch of existing direct insertion terminal.
As a further improvement on the present invention, insulating case height dimension slightly larger than the metal substrate gauge of aluminum base circuit board and thermally conductive insulating layer gauge sum, but is no more than the gross thickness of aluminum base circuit board.Like this, the welding quality between stitch and pad can be improved.
Further improve as of the present invention, the stitch outside dimension being exposed to insulating case part at stitch is identical with insulating case outside dimension.Like this, can prevent scolding tin from penetrating into metal substrate from aluminum base circuit board stitch hole.
Beneficial effect of the present invention is: provide that a kind of structure is simple, low cost of manufacture, the direct insertion terminal being applicable to aluminum base circuit board that easily realizes, makes aluminum base circuit board convenient when circuit design, applies more extensive.
