Description

  The present invention relates to a filter element built-in connector.

  In Patent Document 1, a terminal fitting connected to a wire harness and a grounding member are attached to a synthetic resin housing, and an end portion of a coil accommodated in the housing is connected to the terminal fitting, and a capacitor accommodated in the housing. A filter element built-in connector in which a lead wire is connected to a terminal fitting is disclosed.

Japanese Patent No. 45524318

  In this type of connector, a solder method is usually used as a means for connecting the coil and capacitor lead wires to the terminal fitting. In the connector described in Patent Document 1, the terminal fitting is disposed in the vicinity of the wall portion constituting the housing. Therefore, there is a concern that the synthetic resin wall portion is deformed by heat for melting the solder.

In order to avoid thermal deformation of the wall portion, it is conceivable to use a relay terminal to connect the coil and the terminal fitting and the lead wire and the terminal fitting. However, since the wire diameter of the coil and the wire diameter of the lead wire are greatly different from each other, a dedicated relay terminal is required, and the number of types of parts increases.
This invention is completed based on the above situations, Comprising: It aims at reducing the kind of relay terminal for connecting a terminal metal fitting and a filter element.

The filter element built-in connector of the present invention is
A synthetic resin housing;
A terminal fitting attached to the housing;
A coil that functions as a filter element;
A capacitor having a lead wire smaller in diameter than the coil and functioning as a filter element;
A relay terminal formed with a first connection portion connectable to the coil and a second connection portion connectable to the lead wire;
A first terminal portion formed on the terminal fitting and connectable to the first connection portion;
It is characterized in that it is provided with a second terminal portion formed on the terminal fitting and connectable to the second connection portion.

  If the first connection portion of the relay terminal is connected to the coil and the second connection portion of the relay terminal is connected to the second terminal portion of the terminal fitting, the coil is connected to the terminal fitting. When the second connection portion of the relay terminal is connected to the lead wire and the first connection portion of the relay terminal is connected to the first terminal portion of the terminal fitting, the lead wire is connected to the terminal fitting. Thus, since the relay terminal has the function of connecting the terminal fitting and the coil and the function of connecting the terminal fitting and the lead wire, the relay terminal can be a single type.
