It includes bobbin, primary, secondary coil, iron core and plastic casing, and the both ends of bobbin are along having lateral wall with axis vertically orientation to extending all around, and the upper end of lateral wall is equipped with the connecting seat and both are a body structure, and be equipped with the recess and the foot is connected to outside " L " type on the connecting seat, connects the foot and is made and fixed by metal material on the connecting seat, and the leading -out terminal of coil passes the recess and the outside end welding of being connected the foot, the upper end of connection foot and the jack fixed connection on the circuit board, the utility model provides a current transformer central line finish lead be connected with circuit board wire, the circuit path length, connect unstable cause switch on shortcomings such as loss and leakage inductance, can provide the protect function that stable vary voltage function and inductance leaked, have better convenience and practicality.
Description
Technical field
The utility model relate to a kind of miniature transformer, particularly a kind of circuit board transformer.
Background technology
Transformer is the core parts of power transimission in power supply unit, and it utilizes electric energy, magnetic energy transformation induction principle to adjust voltage, and the loss how reducing transformer is the important means improving power supply unit operational efficiency.The loss of transformer comprises when loss on core loss, coil and finish lead are connected with other conductor welds the leading-out terminal loss formed with cabling.Circuit board transformer is that alternating magnetic field reveals rich and influential family, the traditional circuit-board leading-out terminal of transformer is connected with circuit board by wire, conductor wiring distance, larger conduction loss and leakage inductance can be caused, wire is connected instability with circuit board simultaneously, be subject to vibration influence and come off, thus affecting signal and the transfer of data of whole Circuits System.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of circuit board transformer that can improve connective stability and installation reliability.
In order to achieve the above object, a kind of circuit board transformer designed by the utility model, it comprises bobbin, primary coil, secondary coil, iron core and plastic casing, iron core is " day " font silicon steel core, and be formed by stacking by multi-disc silicon steel sheet, every sheet silicon steel sheet is combined by two panels silicon steel part, this two panels silicon steel part is " E " font and " 1 " font respectively, every sheet " E " font silicon steel part staggered insertion bobbin is also stacked together, " day " font is closed into respectively for every layer by " 1 " font silicon steel part, thus bobbin is set in iron core, primary coil and secondary coil are around on bobbin, centre is separated by catch, the two ends of bobbin are along being extended with sidewall with the direction of axes normal to surrounding, by this sidewall, coil and iron core are isolated, the upper end of sidewall is provided with Connection Block and both are integrative-structure, Connection Block is provided with groove and outside " L " type connecting pin, connecting pin is made up of metal material and is fixed on Connection Block, the leading-out terminal of coil welds with the termination, outside of connecting pin through groove, the upper end of connecting pin is fixedly connected with the jack on circuit board, bobbin, primary coil, secondary coil and iron core are placed in plastic casing, and solidify in a plastic housing by encapsulating, the upper end of connecting pin is exposed outside for being fixedly connected with the jack on circuit board.
The beneficial effects of the utility model are: the utility model provides the novel structure that a kind of transformer is combined with circuit board, solve existing coils in transformers leading-out terminal to be connected with board lead, line route is long, the shortcomings such as the conduction loss that connection instability causes and leakage inductance; The connecting pin coordinated is connected with circuit board by arranging; transformer is made reliably to install on circuit boards; can reduce the loss of conductive structure output and reduce to export leakage inductance, the defencive function providing stable transformation function and inductance to leak, has better convenience and practicality.
