Abstract
The utility model relates to the technical field of transformers, in particular to an improved pin structure of a transformer. The improved pin structure comprises a plurality of welding pins and coil pins, wherein the welding pins are connected with a transformer body and are connected with a circuit board, and the coil pins are wound by coils. On the same side of the transformer body, the welding pins and the coil pins are arranged on adjacent two projections. Each welding pin is provided with a bended welding part and each coil pin is provided with a bended coil hanging part. The bending direction of the welding part is reverse to the bending direction of the coil hanging part. By adopting the structure, on the premise that the overall length of the transformer is not increased, the transformer is ensured to work safely and reliably. Thereby, when the pin structure is adopted, the length of the transformer is shortened.
Description
Technical field:
The utility model relates to the transformer technology field, relates in particular to a kind of pin structure-improved of transformer.

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.
