[Problem that the idea aims to solve]

When using the ground plate 6 described above, there is an opposing barrier 2 and a partition on the back of the connector 1. An enclosed space is created by the wall, ground plate 6, and feedthrough capacitor 7, and this empty space is Solder balls generated during soldering work may remain in between, causing abnormal noises or contact 5. There is a risk of short-circuiting between the ground plate 6 and the earth plate 6. Also, it is difficult to allow cleaning liquid to pass through this space. Therefore, the solder paste remained and the soldering reliability was low.

0004

[Means to solve the problem]

A rectangular conductive plate with a width that corresponds to the distance between the opposing barriers on the back of the straight connector. Form a window that reaches the base of the arm on the arm of the ground plate that is bent into a U-shape. Ru.

[0005] In other words, the present invention has an opposing barrier protruding from the back of a straight connector, and a U-shaped and a ground plate formed with a small through hole that loosely fits into the contact of the connector. A feedthrough capacitor is attached to the small through hole of the ground plate surrounding the back side of the connector. , ground the signal side of the feedthrough capacitor to the contact of the connector by soldering. In a filter connector device whose side is connected to a ground plate, the upper and lower arms of the ground plate A window is formed in the part that reaches the surface of the base to which the feedthrough capacitor is attached. This is a filter connector device characterized by:

[0006]

[Effect]

The window formed on the ground plate is an opening in the space surrounded by the connector barrier and the ground plate. Yes, solder balls generated during soldering work with a feedthrough capacitor attached to the ground plate. Let the water escape and drain through the cleaning solution.

FIG. 1(a) is an external view of one embodiment of the ground plate according to the present invention. (b) is an external view of the same ground plate with the front and back reversed from that of FIG. 1 (a). Figure 2 is , shows an external view of the filter connector device using the ground plate of Fig. 1, and Fig. 3 shows the external view of the filter connector device using the ground plate of Fig. A longitudinal sectional front view taken along the Ro-Ro line (same as the E-I line in FIG. 1) is shown. The symbols are the same as in Figure 4. The same symbols are attached to the minutes. The ground plate 6 is connected to the back of the straight connector 1. It is a conductive plate bent at an obtuse angle into a U-shape that can be fitted between the opposite barriers 2. Ah A T-shaped window corresponding to the partition wall 3 is formed in the center of the base 10 of the base plate 6, and a window is formed around it. Six small through holes 11 are formed in an arrangement corresponding to the contacts 5, and a ground connection is provided above. A counter partition 2 for the terminals is provided. At the upper arm part 8 of the ground plate 6, Windows 13 from the tip to the base are formed on both sides of the shaped notch. , the lower arm part 9 has windows 1 extending from the tip to the base on both sides of the central cut. 4 is formed. The lower arm 9 has only four rods.
