Description

Transformer
Technical field
The present invention relates to a kind of transformer device structure, espespecially a kind of transformer device structure that increases creepage distance between magnetic core group and secondary rolling thread.
Background technology
Transformer is the magnetic element often used in various electric equipment, and it utilizes the principle of electric energy, magnetic energy transformation induction to adjust different voltage, makes it reach the scope that electric equipment can be applicable.
Refer to Fig. 1, its structural representation that is traditional transformer.As shown in the figure, transformer 1 comprises drum stand 10, elementary coiling 11, secondary rolling thread 12 and magnetic core group 13, wherein elementary coiling 11 and secondary rolling thread 12 are set around on drum stand 10, and the leading-out terminal 120 of the leading-out terminal 110 of elementary coiling 11 and secondary rolling thread 12 is wound around respectively and is fixed on the pin 101 extended from drum stand 10 two opposite sides.Magnetic core group 13 is assembled on drum stand 10, and partly is arranged in the path 10 2 of drum stand 10, to complete the assembling operation of transformer 1.Whereby, transformer 1 can utilize its pin 101 and circuit board (not shown) to be electrically connected.
Yet, when the leading-out terminal 110 of elementary coiling 11 is wound around and is fixed on scolding tin on the pin 101 of drum stand 10 1 sides, due between the pin 101 of drum stand 10 and this side apart from shorter, can make and easily mutually be infected with the tin material between two leading-out terminals 110 of elementary coiling 11 and cause short circuit.In addition, be fixed between the leading-out terminal 110 of elementary coiling 11 of pin 101 of drum stand 10, between the leading-out terminal 120 of secondary rolling thread 12, and the leading-out terminal 120 of the leading-out terminal 110 of elementary coiling 11 and secondary rolling thread 12 is respectively and more have the problem of creepage distance deficiency between magnetic core group 13.In addition; when the leading-out terminal 120 of secondary rolling thread 12 is wound around and be fixed on the pin 101 of opposite side of drum stand 10 with scolding tin; winding region to secondary rolling thread 12 line segments that expose between pin 101 for fear of drum stand 10 cause fracture because of External Force Acting; conventional art is meeting sheathed sleeve pipe 14 on secondary rolling thread 12 line segments that expose usually; although the use of sleeve pipe 14 can reach the purpose of protecting secondary rolling thread 12 line segments that expose, derives problems such as expending man-hour and material cost increase.
In addition, in traditional transformer 1, the pin 101 of its drum stand 10 two opposite sides is respectively used to the leading-out terminal 110 of fixing elementary coiling 11 and the leading-out terminal 120 of secondary rolling thread 12, and the pin 110 of two opposite sides is with the symmetric mode spread configuration, thus, when the operation personnel are arranged on circuit board by transformer 1, easily because carelessness misplugs the pin of transformer 1 101 to be located on circuit board the not guide hole of side at the same level and to cause Circuits System to work, even damage.In other words, traditional transformer 1 there is no provides any error-proof structure and can easily and correctly be assembled on circuit board.In addition, traditional transformer 1 is set around elementary coiling 11 and secondary rolling thread 12 on drum stand 10 and by sleeve pipe 14 and is sheathed on secondary rolling thread 12 with manual type, so not only increases human cost, and easily because of the coiling fracture, causes the waste of material.
In view of this, how to develop a kind of transformer, to improve the defect of aforementioned conventional technology, real is current problem in the urgent need to address.
