In addition, connectors that connect conductors between conductors or between conductors and B1 devices generally do not have this kind of noise prevention measures, and if they are used, expensive connectors with internal noise filter elements must be used. . This connector needed to be fixed directly to the equipment and connect the ground directly to the equipment.

Therefore, if a wire harness connector with internal specifications can be used as a noise prevention type, there will be no need to cover the conductor wires with expensive tape or tubes, and the burden on the equipment side will be reduced.

The present invention has been made based on the above viewpoints,
The purpose of this is to make it possible to cut the noise radio waves transmitted through the core wire -F at the connection point of the wire harness connector by incorporating a noise prevention mechanism into each individual connector housing. (Means for solving the problem) To achieve the above object, the present invention provides a noise prevention connector for harness relay. and a capacitor assembly disposed on the outer periphery of each terminal.
The power supply capacitor and the
Each capacitor is fitted and fixed in a state in which the external electrode is electrically connected to the connector housing, and the connector housing includes a grounding conductive plate that is common to each capacitor installed in the connector housing.

(Function) According to the above configuration, the outer periphery of each terminal is surrounded by a feedthrough capacitor, and due to the action of this capacitor, noise radio waves, which are high frequency components carried on the conductor, are attenuated.
removed. Further, according to the present invention, when the relay noise prevention connector is not mounted, it can be used as a connection connector for a wire harness, and by changing the specifications, m? 1 prevention type, it is only necessary to mount the relay M7'A prevention] connector, so it is possible to easily change the wire harness connection connector with the same specifications to the normal type and the 911 noise prevention type.
