Abstract
The utility model discloses the surface-pasted transformer of a kind of employing, comprising: a plastic casing; One coiling group, this coiling group is arranged in described plastic casing; Draw at least one group of link pin from coiling group, this link pin is drawn from least one side of plastic casing and described link pin is in a row arranged.Wherein, the foot of link pin and the bottom surface of plastic casing are at same plane.The volume of transformer can be reduced, more can be suitable for high accuracy, small size product when installing transformer, only the link pin of transformer just just can need be realized Fast Installation to the link on circuit board by laser electric welding and connect, applicable large-scale production; Moreover, because the foot of link pin and the bottom surface of plastic casing are at same plane, therefore can realize transformer and pasted on surface of circuit board, the stability after installation can be increased.
Description
Technical field
The utility model relates to transformer technology field, especially relates to a kind of surface mount mode that adopts and realizes the transformer encapsulated.
Background technology
Transformer (Transformer) utilizes the principle of electromagnetic induction to change the device of alternating voltage, and main member is primary coil, secondary coil and iron core (magnetic core).Major function has: voltage transformation, current transformation, impedance transformation, isolation, voltage stabilizing (magnetic saturation transformer) etc.Can be divided into by purposes: distribution transformer, power transformer, full-sealed transformer, combined transformer, dry-type transformer, oil-filled transformer, single-phase transformer, furnace transformer, rectifier transformer etc.
Its volume ratio of the transformer of current use is comparatively large, takes up room large, is difficult to the requirement meeting scientific and technological high speed development day by day; Especially, for high precision, the electronic product of small size, if use traditional transformer its to take volume large; And when being connected with circuit board, being mostly that employing two or more pin are inserted in the jack of circuit board, then linking together with circuit board through welding.But this connected mode can not meet the demand of present product, the first, adopt pin to inject the mode of jack connection, it takes up room greatly; The second, this connected mode is unfavorable for industrial mass production, and efficiency is low.
Utility model content
The utility model, in order to overcome the deficiencies in the prior art, its objective is and provides a kind of micro-circuit board that is applicable to install, be suitable for the little and little transformer that takes up room of large-scale production, volume.
In order to solve above-mentioned technical problem, the basic technical scheme that the utility model proposes is: the surface-pasted transformer of a kind of employing, comprises,
One plastic casing;
One coiling group, this coiling group is arranged in described plastic casing;
Draw at least one group of link pin from coiling group, this link pin is drawn from least one side of plastic casing and this link pin is in a row arranged.
In the surface-pasted transformer of employing described in the utility model, described link pin is arranged on the lower part of at least one side of plastic casing and the bottom surface of close plastic casing.
In the surface-pasted transformer of employing described in the utility model, the foot of described link pin and the bottom surface of plastic casing are at same plane.
In the surface-pasted transformer of employing described in the utility model, described link pin is provided with two rows, and is arranged on two relative sides of plastic casing.
In the surface-pasted transformer of employing described in the utility model, described coiling group comprises and is wound on elementary coiling in FERRITE CORE and secondary rolling thread, and described elementary coiling and secondary rolling thread side-by-side parallel are placed and turn to primary coil and secondary coil along FERRITE CORE in the lump.
In the surface-pasted transformer of employing described in the utility model, described FERRITE CORE is annular.
In the surface-pasted transformer of employing described in the utility model, described plastic casing is the tetragonal body structure of flat.
The beneficial effects of the utility model are:
The utility model adopts elementary coiling and secondary rolling thread side-by-side parallel place and turn to the technology of primary coil and secondary coil in the lump along FERRITE CORE, can be reduced the volume of transformer, more can be suitable for the product of high accuracy, small size by this technology; In addition, coiling group draws at least one group of link pin, this link pin is drawn from least one side of plastic casing and described link pin is in a row arranged, this technology makes link pin draw from a side or many sides, be similar to the structure of electronic devices and components, consistent with the connected mode of general electronic devices and components and circuit board, when installing transformer, only the link pin of transformer just just can need be realized Fast Installation to the link on circuit board by laser electric welding to connect, be applicable to large-scale production; Moreover, because the foot of link pin and the bottom surface of plastic casing are at same plane, therefore can realize transformer and pasted on surface of circuit board, the stability after installation can be increased.

Embodiment
Be described further below with reference to accompanying drawing 1 to accompanying drawing 4 pairs of the utility model, but protection range of the present utility model should do not limited with this.
1 to accompanying drawing 4 by reference to the accompanying drawings:
The surface-pasted transformer of employing described in the utility model comprises:
One plastic casing 10;
One coiling group 20, this coiling group 20 is arranged in described plastic casing 10;
Draw at least one group of link pin 30 from coiling group 20, this link pin 30 is drawn from least one side of plastic casing 10 and described link pin 30 is in a row arranged.
In the present embodiment, link pin 30 is set to two rows, lays respectively at left surface 101 and the right flank 102 of the arranged on left and right sides of plastic casing 10.And, each row's link pin 30 is arranged side by side and is yi word pattern, concrete, each row's link pin 30 be all be positioned at left surface 101 and right flank 102 bottom near the bottom surface of plastic casing 10, the foot 301 of link pin 30 and the bottom surface 103 of plastic casing 10 are at same plane.When mounted, then transformer is fixed by the mode of laser spot welding by the installation position that only transformer need be placed on circuit board.
The elementary coiling 201 of coiling group 20 and secondary rolling thread 202 side-by-side parallel are placed and turn to primary coil and secondary coil along FERRITE CORE 203 in the lump, and this technology greatly reduces the volume of coiling group 20, can greatly meet in high-precision miniature electronic product.
