Claims

[Claims for Utility Model Registration] 1 Consisting of a pair of magnetic core pieces each having a joint surface and forming a closed magnetic path by crimping one joint surface to the other joint surface, the pair of magnetic core pieces In a data line filter comprising a core in which a data line insertion passage is formed between the core pieces, and a fixture for combining and fixing the pair of magnetic core pieces, the pair of magnetic core pieces are connected to each other. A pair of cases that can be opened and closed are housed with the bonding surfaces exposed, and an elastic fixing device having an annular partially cut out shape is fitted into the outer circumferential surface of the pair of cases, and the elasticity of the fixing device allows the pair of cases to be opened and closed. A filter for a data line, characterized in that the cases of the above are joined together, and the joint surfaces of the pair of magnetic core pieces are pressed together. 2 Consists of a pair of magnetic core pieces each having a bonding surface and forming a closed magnetic path by crimping one bonding surface to the other bonding surface, with a data line insertion path between the pair of magnetic core pieces. In a data line filter comprising a core in which a magnetic material core is formed and a fixture for combining and fixing the pair of magnetic core pieces, the pair of magnetic core pieces are placed in a pair of cases with the bonding surfaces exposed, respectively.
