Description
Technical field
The present invention relates to a kind of drum stand and transformer, refer to a kind of transformer that has the drum stand of clamping pin and utilize this drum stand especially.
Background technology
Transformer is the electronic component that often uses in the various electric equipment, and in order to adjust different voltage, making voltage reach electric equipment can applicable scope, and then electric equipment is moved.Usually, the structure of transformer mainly comprises drum stand, magnetic core set, elementary coiling and secondary rolling thread, the coil of wherein elementary coiling and secondary rolling thread is made up of a plurality of single-core lines stranded (or claiming multi cord) institute respectively, and the coil of elementary coiling and secondary rolling thread is set around the winding region of drum stand, therefore transformer just can pass through in elementary coiling input voltage, behind the electromagnetic action of magnetic core set, reach the purpose of voltage transitions in secondary rolling thread.In addition, a plurality of identical pins are set also on the drum stand, are fixedly welded on it for the outlet portion of elementary coiling and secondary rolling thread.In addition, a plurality of pins also can be used to be connected with the guide hole of circuit board, and transformer is fixed on this circuit board.
The leg structure of general drum stand is broadly divided into two kinds of simple root pin and L formula pins, because transformer now must carry big electric current, so the simple root pin is when welding outlet portion, pin after the more and coiling of the quantity of required a plurality of single-core line stranded (or claim multi cord) is thicker, cause welding inconvenience easily, defectives such as pin short circuit and tin awl are too big, and because the pin of drum stand is too thin, in the process of twining outlet portion, can cause the pin distortion, and be unfavorable for being connected with the guide hole of circuit board, moreover, the outlet portion of a plurality of single-core lines stranded (or claiming multi cord) winds the line when pin, and its step is complicated and the reason line is difficult, therefore quite expends man-hour.On the other hand, though L formula pin improves the part defective of above-mentioned simple root pin, but because the outlet portion of a plurality of single-core lines stranded (or claiming multi cord) still must be strapped in together and be welded in the following foot section of L formula pin, so wayward thickness of foot section down, thereby make the perforate size on the circuit board also wayward, when the following foot section of pin when guide hole on the circuit board is connected, the phenomenon of take place easily to overflow tin or Xi Dong.In addition, if the material of drum stand is the thermoplasticity material, when carrying out that outlet portion is welded in the work of pin, welding gun can contact with drum stand unavoidably, thereby causes the drum stand melting loss and cause the problem of pin displacement.
Summary of the invention
Purpose of the present invention is for providing a kind of drum stand, it improves the pin of existing drum stand, be clamped on the clamping part of pin in order to outlet portion coiling, existing pin is too thick, welding is inconvenient, the tin awl is too big and the defective of easy short circuit to solve, and avoid the pin distortion and reduce the man-hour of managing line, and then effective phenomenon of improving overflow tin or Xi Dong, in addition, also solve the problem that has the drum stand melting loss now and cause the pin displacement.
Another object of the present invention is for providing a kind of transformer, it has, and pin is not yielding, the reason line easily, effect such as when reducing the reason lineman, and eat the bad problem of tin can avoid getting a foothold the time.
For reaching above-mentioned purpose, of the present invention one than broad sense embodiment for a kind of transformer is provided, comprising: at least one elementary coiling and at least one secondary rolling thread; Drum stand comprises: body has at least one winding region, with elementary coiling of winding and secondary rolling thread; First connecting seat is arranged at the body bottom; And a plurality of clamping pins, be arranged at first connecting seat, and each this clamping pin having a clamping part, the outlet portion of elementary coiling of this clamping part clamping or secondary rolling thread is on first connecting seat; And magnetic core set, be arranged in the drum stand to small part.
For reaching above-mentioned purpose, of the present invention another than broad sense embodiment for a kind of drum stand is provided, comprising: body has at least one winding region, with at least one coiling of winding; Connecting seat is arranged at the body bottom; And at least one clamping pin, this clamping pin is arranged at connecting seat and has a clamping part, and the outlet portion of this clamping part clamping coiling is on connecting seat.
Beneficial effect of the present invention is, drum stand of the present invention, it has improved the pin of existing drum stand, be clamped on the clamping part of pin in order to outlet portion coiling, solved that existing pin is too thick, welding inconvenience, the easy short circuit of pin and the too big defective of tin awl, and owing to outlet portion must be wound in the clamping pin, therefore can not cause the pin distortion, and can reduce the man-hour of managing line, moreover, the length and the sectional area of the junction of all clamping pins are fixed, thereby the size of guide hole on can control circuit board, further effectively improve the phenomenon of overflow tin or Xi Dong.On the other hand, when welding outlet portion, welding gun must contact with drum stand and outlet portion can be welded on the clamping pin, has solved existing drum stand melting loss and the problem that causes pin to be shifted.
