Background technology
Transformer framework is the agent structure part of electronic transformer.Its Main Function has: for the copper cash in transformer provides the space of winding, and for carrying magnetic core.In the various safety standard such as IEC, UL, CE, in safe distance (electric clearance and creepage distance), have detailed hard and fast rule to the electronic transformer as electrical isolation device.At present, existing power supply is towards the future development of miniaturization, its volume becomes more and more less, therefore the volume of transformer framework also becomes more and more less, how to ensure that electronic transformer skeleton is while meeting power supply miniaturization, can meet again the safe distance of various safety standard, be the technical barrier that those skilled in the art need to solve.
Existing transformer framework meet safe distance general measures be directly strengthen the spacing between the primary coil groove of transformer framework and secondary wire ring recess, and auxiliary to protect with insulating material such as barricade, gummed paper, Teflon sleeve pipes, this measure not only increases the volume of transformer framework, add Material Cost, and be unfavorable for reducing transformer whole volume, be also unfavorable for reducing circuit board cloth board space simultaneously; Or be the mounting structure adopting secondary fly line, necessary distance is met by fly line welding hole on circuit boards, but because the technique management and control difficulty of fly line is larger, and the upper plate of fly line installs more difficult operation, not only require higher to the professional skill of operating personnel, and the operating time is long, thus improve production cost.
Utility model content
For overcoming the deficiencies in the prior art and Problems existing, the utility model provides a kind of transformer framework structure, it is simple that this transformer device structure has structure, meet safety safe distance while effectively can reduce the volume of voltage device skeleton and effectively reduce the advantages such as production cost.
The utility model is achieved through the following technical solutions: a kind of transformer framework structure, comprise the frame body be arranged on pcb board, described frame body comprises the spiral portion with mesopore, lay respectively at the elementary end stand at two ends, spiral portion and secondary end stand, the bottom of elementary end stand and secondary end stand is fitted with many respectively for the metal pins be electrically connected, two dividing plates are provided with between the bottom of described secondary end stand and described spiral portion, a line outlet groove is formed between two dividing plates, a baffle plate is also provided with in the bottom of described secondary end stand, between the metal pins of this baffle plate on described dividing plate and secondary end stand, described pcb board is provided with the opening mated with described baffle plate, the height of described baffle plate is greater than the height of described dividing plate, and described baffle plate is through described opening.
Preferably, the length on the bottom that the length of described baffle plate is greater than described secondary end stand between two outermost metal pins, and the height of described baffle plate is greater than the height of described metal pins; The both sides of described baffle plate are provided with recess.
Preferably, a skewed slot is also provided with bottom described line outlet groove; The two ends of described two dividing plates are concordant with the outermost end of described secondary end stand, and the contact-making surface of two dividing plates and pcb board is horizontal plane.
The transformer framework structure that the utility model provides, by arranging a baffle plate the secondary of transformer framework, and on pcb board, be provided with the opening mated with this baffle plate, make to make this baffle plate through described opening when installing transformer, make the safe distance that also effectively can meet safety while the volume reducing transformer framework, and easy for installation, simplify the manufacture craft of transformer, and effectively can reduce production cost.
Accompanying drawing explanation
Fig. 1 is the perspective view of transformer framework described in the utility model embodiment;
Fig. 2 is the mounting structure schematic diagram of transformer framework described in the utility model embodiment.
Embodiment
For the ease of the understanding of those skilled in the art, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in accompanying drawing 1 and Fig. 2, a kind of transformer framework structure, comprise the frame body 20 be arranged on pcb board 10, described frame body comprises the spiral portion 21 with mesopore, lay respectively at the elementary end stand 22 at two ends, spiral portion and secondary end stand 23, the bottom of elementary end stand and secondary end stand is fitted with many respectively for the metal pins 24 be electrically connected, two dividing plates 25 are provided with between the bottom of described secondary end stand and described spiral portion, a line outlet groove 251 is formed between two dividing plates, a baffle plate 26 is also provided with in the bottom of described secondary end stand, between the metal pins 24 of this baffle plate 26 on described dividing plate 25 and secondary end stand, described pcb board is provided with the opening mated with described baffle plate, the height of described baffle plate is greater than the height of described dividing plate, and described baffle plate is through described opening.In the present embodiment, length (length of namely described baffle plate is greater than the length of L shown in Fig. 2) on the bottom that the length of described baffle plate is preferably greater than described secondary end stand between two outermost metal pins, and the height of described baffle plate is greater than the height of described metal pins, effectively intercept to be formed between the metal pins and the metal pins of secondary end stand of elementary end stand, thus increase effectively the electric clearance between the metal pins of elementary end stand and the metal pins of secondary end stand.The two ends that must bypass described baffle plate due to the outlet being wrapped in the copper cash in spiral portion just can be wound on the metal pins in secondary end stand, so effectively increase the creepage distance of outlet; And because this baffle plate is through the opening of pcb board, at the part pin of primary end, formed between the metal pins of Copper Foil and secondary end stand and effectively intercept, thus increase effectively the part pin of primary end, the electric clearance between the metal pins of Copper Foil and secondary end stand; Therefore, the transformer framework structure that the present embodiment provides, while effectively ensureing that transformer framework meets power supply miniaturization, can also meet the safe distance of transformer in each safety standard well.
In a preferred embodiment, be also provided with a skewed slot bottom described line outlet groove, the both sides of described baffle plate are provided with recess, to make the copper cash outlet well in spiral portion, simplify manufacture craft.In addition, the two ends of described two dividing plates are concordant with the outermost end of described secondary end stand, and the contact-making surface of two dividing plates and pcb board is horizontal plane, is beneficial to the installation of transformer; In addition, described baffle plate, through the opening of pcb board, is also more conducive to the installation of transformer with fixing.
Utilize the transformer framework structure that the present embodiment provides, meet safety safe distance while effectively can reduce the volume of voltage device skeleton, and effectively simplify the manufacture craft of transformer, and install simple and convenient, effectively can reduce production cost.
Above-described embodiment is preferably implementation of the present utility model, is not to restriction of the present utility model, and under the prerequisite not departing from inventive concept of the present utility model, any apparent replacement is all within protection range of the present utility model.
