Abstract
A transformer includes a magnetic core assembly and a hollow pad. The magnetic core assembly includes a first magnetic part and a second magnetic part. Each of the first magnetic part and the second magnetic part includes a middle post. The hollow pad is arranged between the middle post of the first magnetic part and the middle post of the second magnetic part. The hollow pad has an opening for accommodating a gluing material. The first magnetic part and the second magnetic part are combined together through the gluing material.
Claims23
A transformer without a bobbin, comprising:
- a magnetic core assembly comprising a first magnetic part and a second magnetic part, wherein each of said first magnetic part and said second magnetic part comprises a middle post;
- and
- a hollow pad arranged between said middle post of said first magnetic part and said middle post of said second magnetic part, wherein said hollow pad has an opening for accommodating a gluing material, wherein said first magnetic part and said second magnetic part are combined together through said gluing material.
A transformer, comprising:
- a bobbin comprising a main body and a channel, wherein said channel runs through said main body;
- a magnetic core assembly comprising a first magnetic part and a second magnetic part, wherein each of said first magnetic part and said second magnetic part comprises a middle post, and said middle post is partially inserted into said channel;
- a hollow pad arranged between said middle post of said first magnetic part and said middle post of said second magnetic part, wherein said hollow pad has an opening for accommodating a gluing material, wherein said first magnetic part and said second magnetic part are combined together through said gluing material;
- and
- at least a first position-limiting device disposed on an inner wall of said channel, wherein when said middle post of said first magnetic part and said middle post of said second magnetic part are disposed corresponding to each other from the two sides of said channel, said first position-limiting device is disposed between said middle posts of said first magnetic part and said second magnetic part and said inner wall of said channel, thereby limiting the positions of said middle post of said first magnetic part and said middle post of said second magnetic part.
A transformer, comprising:
- a bobbin comprising a main body and a channel, wherein said channel runs through said main body;
- a magnetic core assembly comprising a first magnetic part and a second magnetic part, wherein each of said first magnetic part and said second magnetic part comprises a middle post, and said middle post is partially inserted into said channel;
- a hollow pad arranged between said middle post of said first magnetic part and said middle post of said second magnetic part, wherein said hollow pad has an opening for accommodating a gluing material, wherein said first magnetic part and said second magnetic part are combined together through said gluing material;
- and
- two first position-limiting devices respectively disposed on a sidewall of said middle post of said first magnetic part and said middle post of said second magnetic part, wherein when said middle post of said first magnetic part and said middle post of said second magnetic part are disposed corresponding to each other from the two sides of said channel, said first position-limiting devices are disposed between said middle posts of said first magnetic part and said second magnetic part and an inner wall of said channel, thereby limiting the positions of said middle post of said first magnetic part and said middle post of said second magnetic part.
