Description
Technical field:
The utility model relates to the transformer technology field, relates in particular to a kind of pin structure-improved of transformer.
Background technology:
As shown in Figure 1, this is the transformer reel body 10 of a two-in-one structure, drum stand body 10 is provided with an elementary winding section 101 and two secondary rolling thread portions 102, a wherein side of elementary winding section 101 is provided with two convexes 103, two convexes 103 are respectively arranged with welding pin 104 that is used for soldered circuit board and the coil pin 105 that is used for connecting coil, described coil pin 105 is metal needles of a wire, and described coil pin 105 is vertically set on the lateral surface of convex 103.Can be smoothly the buttock line of coil be wrapped in coil pin 103 and touch welding pin 104 in order to ensure the eedle of automatic coil winding machine, must have enough big gap between welding pin 104 and the coil pin 105, during transformer work, can produce electromagnetic interference between two adjacent coil pins 105, in order to ensure transformer energy operate as normal, must guarantee has enough distances between two adjacent coil pins 105.In the transformer of two-in-one structure, in elementary winding section 101, distance between two adjacent coil pins 105 is to guarantee to have enough big, and also must have enough big gap between welding pin 104 on the same convex 103 and the coil pin 105.Therefore, all be in safe distance, can only increase the length of drum stand body 10 in order to ensure distance between the distance between two coil pins 105 and welding pin 104 on the same convex 103 and the coil pin 105.At present, this transformer is widely used in LCDs and other electric equipment, along with electric equipment develops towards microminiaturized, slimming, require the volume of transformer also more and more littler, therefore, the leg structure of existing transformer has limited the volume of transformer, makes that the volume of transformer can not be too small.
The utility model content:
The purpose of this utility model is to provide at the deficiencies in the prior art a kind of pin structure-improved of transformer, by changing the structure of coil pin, the length of transformer can be shortened, and makes that the existing volume of transformer of volume ratio of transformer is little.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of pin structure-improved of transformer, comprise several the coil pins that are connected in the welding pin that is used for the connecting circuit plate of transformer body and are used for winding around, the same side at the transformer body, adjacent two convexes are provided with welding pin and coil pin, described welding pin is provided with the weld part of bending, described coil pin is provided with the hanging wire portion of bending, and described weld part is opposite with the wrap direction of described hanging wire portion.
Described hanging wire portion and described coil pin are bendings at an angle.
Preferably, the angle of described hanging wire portion and described coil pin bending formation is the right angle.
Preferably, the angle of described hanging wire portion and described coil pin bending formation is the obtuse angle.
The beneficial effects of the utility model: the coil pin is provided with the hanging wire portion of bending, the lead-in wire of coil is wrapped in the hanging wire portion, and hanging wire portion with the welding pin not on same horizontal plane, though the distance between coil pin and the welding pin is closer, but do not influence the hanging wire portion that automatic coil winding machine is wrapped in the lead-in wire of coil the coil pin, distance between coil pin and the welding pin reduces, make the distance between the adjacent coil pin increase, under the prerequisite that does not increase the transformer entire length, still can guarantee transformer safety, steady operation, therefore, adopt leg structure of the present utility model after, can shorten the length of transformer.
