Abstract
Official abstract text for this publication.
A reactor includes a terminal block having a plurality of terminals which is coupled to one end of a core body. A plurality of surge protection elements are connected to the plurality of terminals inside the terminal block. Input side extension portions and output side extension portions extending from coils are connected to the plurality of terminals of the terminal block, and a plurality of surge protection elements are connected to the input side extension portions and the output side extension portions, respectively.
First claim
Opening claim text (preview).
The invention claimed is: 1. A reactor, comprising: a core body, the core body comprising: an outer peripheral iron core, at least three iron cores which are arranged so as to contact or so as to be coupled with the inside of the outer peripheral iron core, and coils wound onto the iron cores, wherein gaps, which can be magnetically coupled, are formed between one of the at least three iron cores and another iron core adjacent thereto, the reactor further comprising: a terminal block having a plurality of terminals and coupled to one end of the core body, and a plurality of surge protection elements which are connected to the plurality of terminals inside the terminal block, wherein input side extension portions and output side extension portions extending from the coils are connected to the respective terminals of the terminal block, and the plurality of surge protection elements are connected to the input side extension portions and the output side extension portions, respectively. 2. The reactor according to claim 1 , wherein each of the plurality of surge protection elements includes at least one of a capacitor, a varistor, and a surge absorber. 3. The reactor according to claim 1 , wherein the each of plurality of surge protection elements are connected to the terminals via a resin-molded circuit board which forms a part of a wall portion of the terminal block. 4. The reactor according to claim 1 , wherein the number of the at least three iron cores is a multiple of three. 5. The reactor according to claim 1 , wherein the number of the at least three iron cores is an even number not less than four.
