Description

Transformer device structure

Technical field

This case is about a kind of transformer device structure, and espespecially a kind of have a upper and lower pin on drum stand, with the transformer device structure being electrically connected with a vertical auxiliary circuit board.

Background technology

Transformer is the magnet assembly often using in electric equipment, and it utilizes electromagnetic induction principle and changes and adjust voltage, makes voltage reach the scope that electric equipment can be applicable.Generally speaking, the structure of traditional transformer mainly comprises drum stand, magnetic core group, elementary coiling and secondary rolling thread.Wherein, the coil of elementary coiling and secondary rolling thread is set around the winding region of drum stand, and transformer can, by elementary coiling input voltage, after the electromagnetic action of magnetic core group, reach the object of voltage transitions in secondary rolling thread.

Traditional transformer device structure is as shown in Figures 1 and 2, wherein transformer 1 is mainly consisted of drum stand 10, magnetic core group 11 and winding (not shown), wherein winding comprises primary side coiling (not shown) and secondary side coiling (not shown), and the structure of drum stand 10 as shown in Figure 2, mainly comprise body 100, this winding is set around on the body 100 of drum stand 10, and, in the bottom of body 100, more comprise the two corresponding pedestals 101 that arrange, on pedestal 101, have more a plurality of pins 102 to downward-extension, in order to be plugged on circuit board 2.

Therefore after on the primary side coiling of winding and the corresponding body 100 that is set around drum stand 10 of secondary side coiling, can by the pin 102 on its both sides pedestal 101, carry out outlet respectively, again magnetic core group 11 correspondences are coated on to drum stand 10 and arrange, like this can complete the assembling of transformer 1, thereafter, again transformer 1 is inserted on circuit board 2, the plurality of pin 102 is electrically connected to the circuit (not icon) on circuit board 2, can complete structure as shown in Figure 1.Yet, in the application aspect of this known transformer, because the primary side coiling of known transformer 1 need be through a control circuit 20 to carry out the control of voltage, and this control circuit 20 need be arranged at the enterprising row wiring of circuit board 2, therefore can cause circuit board 2 need have more space so that this control circuit 20 to be set, in other words, the length h1 of circuit board 2 is therefore control circuit 20 and increasing, thus, the size of transformer 1 and circuit board 2 and application thereof can be therefore limited, and then make product cannot reach the target of slimming.

Refer to Fig. 3, it is arranged at the schematic diagram on main circuit board for another known transformer.As shown in the figure, this transformer 3 is consisted of drum stand 30, magnetic core group 31 and coiling (not shown) equally, the bottom of drum stand 30 has the pedestal 301 of two corresponding settings equally, and wherein a pedestal 301 has the pin 301a to downward-extension, and transformer 3 is also arranged on main circuit board 4.Exist with the difference of aforementioned known transformer 1, in the application aspect of this transformer 3, in order to reduce the length of main circuit board 4, and adopted a vertical auxiliary circuit board 40 to carry out corresponding electrical connection with transformer 3 and main circuit board 4, and control circuit 41 is arranged on this auxiliary circuit board 40, with the primary side coiling (not shown) with transformer 3, be electrically connected to.

Yet, in this known techniques, for the control circuit 41 that makes to be arranged on vertical auxiliary circuit board 40 is electrically connected with main circuit board 4, the pedestal 301 of drum stand 30 bottoms of the transformer 3 corresponding with it more needs to arrange a junction 302, and this connecting portion 302 is arranged at the leading-out terminal of primary side coiling (not shown), again for the input in response to voltage and output, on this connecting portion 302, need to arrange the pin 302a of 2 times, and, in order to maintain many groups Voltage-output of transformer 3, between each pin 302a, need the distance that remains certain, to maintain its electrical safety.Therefore, as shown in Figure 3, though the main circuit board 4 of visible this known techniques is because having reduced control circuit 41, and its length h3 is comparatively reduced compared to last embodiment, yet in response to the set pin 302a more than 2 times of transformer 3, its width h4 is compared to the width h2 of last known techniques, real in increasing.Though so transformer 3 arranges with auxiliary circuit board 40 combinations, so still cannot effectively reach and make the area of main circuit board 4 reduce or make it can supply the space increase of using.

In view of this, how to develop a kind of auxiliary circuit board that can be vertical with one and be electrically connected to increase the wiring space of main circuit board or the area that can reduce main circuit board, more can reduce the transformer device structure of the heat dissipation of main circuit board wiring cost and enhancement transformer and control circuit, real is correlative technology field person problem in the urgent need to address at present.
