る。 According to the above embodiment, the connector 1, which has a terminal structure that can be fitted to a standard product connector on the automobile side, is integrated with a case containing a built-in noise eliminating element, so that the troublesome wiring work and noise filtering required in the past are avoided. This eliminates the need for fixing the main body, and can be installed by simply fitting it into a connector that has a receptacle provided on the vehicle side. In addition, by making one of the Faston terminals a short terminal and the other a long terminal having an L-shaped extension, it is possible to electrically connect a noise removal element between the short terminal and the long terminal, thereby reducing noise. It is possible to eliminate the need for a substrate or wiring for interconnecting the removal elements. Furthermore, since the case 7 is composed of two half-case bodies 8A and 8B, it is extremely easy to assemble the inside of the case, and each half-case body 8A and 8B can be used to position the noise removal element and for mutual insulation. By forming the ribs 16, 17, 19, the chiyoke coils 20A, 2 as noise removing elements
Positioning of 0B and capacitor 23 becomes easy,
Reliability against vibrations and the like can also be improved.
なお、自動車の車種や用途に応じてコネクタの
