  • Patent number: 8203415
    Abstract: A bobbin structure is disclosed. The bobbin structure comprises plural modular bobbin members each connected with each other. Each modular bobbin member comprises a perforation channel, a first baffle disposed on one end of the perforation channel and placed perpendicularly to the perforation channel, and a second baffle disposed on the other end of the perforation channel and placed oppositely to the first baffle. The first baffle has a first connecting member, and the second baffle has a second connecting member. A first winding slot is disposed between the first baffle and the second baffle. The bobbin structure is formed by the engagement between the first connecting member of one modular bobbin member and the second connecting member of another connected one, wherein a second winding slot is formed between two connected modular bobbin members.

  • Patent number: 7969271
    Abstract: A current transformer includes a bobbin, a primary winding coil, a conductive pillar, a magnetic core assembly, and a covering member. The bobbin includes a bobbin body and a concave structure. The primary winding coil is wound around the bobbin body. The conductive pillar is partially accommodated within the concave structure. The magnetic core assembly includes a first magnetic core and a second magnetic core. The first magnetic core and the second magnetic core are partially embedded into the channel. The concave structure is partially enclosed by the second magnetic core. The covering member cooperates with the concave structure to shield the conductive pillar. The conductive pillar and the second magnetic core are separated from each other by the covering member, so that a creepage distance between the conductive pillar and the primary winding coil and a creepage distance between the conductive pillar and the magnetic core assembly are increased.
