[0002]

2. Description of the Related Art In recent years, higher and higher frequencies and higher output of electrical products have been in progress. Along with this, the influence of interference waves cannot be ignored.

An example of a conventional connector will be described below with reference to the drawings. In FIG. 3, 31 is a connector mounted on the printed circuit board 32, 33 is a chip capacitor also mounted on the printed circuit board 32, and 34 is a wiring pattern. The connector 31 of the conventional example configured as described above serves as an electrical connection medium with another electric circuit.

However, in the above configuration, the mounting position of the chip capacitor 33 on the printed board 32 differs depending on the wiring pattern 34 formed on the printed board 32. Therefore, the interfering wave that has entered the connector 31 from the outside is normally dropped by the chip capacitor 33. However, depending on the wiring pattern 34, the wiring of the chip capacitor 33 becomes long, so that the effect of removing the interfering wave is lost. There was something that happened.

In the conventional example shown in FIG. 4, the connector 4 is used.
1 is mounted on the printed circuit board 42, and the chip inductor 43 and the chip capacitor 44 are also mounted on the printed circuit board 42 in accordance with the wiring pattern 45. Like the connector 31 shown in FIG. 3, the connector 41 shown in FIG. 4 serves as an electrical connection medium with another electric circuit, but the wiring formed on the printed board 42. Depending on the pattern 45, the mounting positions of the chip inductor 43 and the chip capacitor 44 may change greatly. Therefore, the interference wave that has entered the connector 41 from the outside should normally be dropped by the low-pass filter including the chip inductor 43 and the chip capacitor 44, but the wiring becomes long depending on the wiring pattern 45, and the effect of removing the interference wave is obtained. Sometimes disappeared.

[0006]

A conventional problem to be solved by the present invention is that a capacitor for removing an interfering wave or an inductor and a capacitor which are components of a low-pass filter are affected by a wiring pattern on a printed circuit board. That is, it may be mounted at a position away from the connector and may not play a role of removing the interference wave.

An object of the present invention is to solve the conventional problems, and an object thereof is to provide a connector capable of removing an interfering wave without being influenced by a wiring pattern.
