DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of manufacturing a filter connector device in which a feedthrough capacitor is incorporated in an angle type connector.

[0002]

2. Description of the Related Art Conventionally, a connector in which a horizontal portion of an inverted L-shaped contact is provided through a back wall of an insulating connector body is called an angle type connector. This angle type connector (hereinafter,
In order to prevent the noise that passes through the contact, a feed-through capacitor is incorporated,
A conventional filter connector device uses a ground plate having a size that allows only the hanging part of the contact to be inserted, or a ground plate having a size that can also contact the bottom surface of the connector body. Each small through hole is formed. Then, the small diameter portion is inserted through the small through hole to mount the rivet-shaped feedthrough capacitor on the ground plate.

Such a conventional angle type connector is
The feed-through capacitor is pierced through the hanging part of the contact from the large diameter side, the ground plate and the feed-through capacitor are combined with the connector, and the feed-through capacitor and the contact and the ground plate are connected and fixed by soldering at a predetermined part of the hanging part. It was made.

[0004]

In the case of a filter connector device that uses a ground plate that does not come into contact with the bottom surface of the connector body, the lower end surface of the feedthrough capacitor should be sufficiently separated from the substrate when mounted on a wiring substrate. In order to fix the feedthrough capacitor at the middle height of the hanging part, a positioning jig was required and the soldering work was troublesome.

When using a ground plate that comes into contact with the bottom surface of the connector body, there are two types of connector body, one with or without a mounting base on the bottom surface, both of which do not require a positioning jig. It was necessary to carry out the soldering work while keeping the plate in contact with the bottom surface by an appropriate means. In the case of the former connector body, the feedthrough capacitor comes into contact with the board when it is mounted on the wiring board, so when the contact and the conductor of the board are connected by immersion soldering, the solder fixing the feedthrough capacitor melts. The feedthrough capacitor sometimes floated away from the ground plate.

Further, in the conventional filter connector device,
When a failure is found in the withstand voltage and capacity inspection of the built-in feedthrough capacitor, only the bad feedthrough capacitor cannot be replaced with a good product. All of the feedthrough capacitors were removed together with the ground plate from the hanging parts of the contacts, and the defective product was replaced with a good product. The ground plate and feedthrough capacitor were then combined with the connector and repaired. There was a problem that the number of man-hours for replacement work was extremely large.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a method of manufacturing a filter connector device in which a feedthrough capacitor can be easily assembled to a connector and the feedthrough capacitor can be easily replaced.

[0008]

According to the present invention, a contact is pierced through a back wall of a connector body having a bottom surface protruding from a mounting base having a recess on the side surface, and the contact body is bent downward at a right angle. In a method of manufacturing a filter connector device in which an angle-type connector, a ground plate and a feedthrough capacitor are combined, the ground plate has a plurality of small through holes corresponding to the hanging parts of the contacts, and a tongue piece corresponding to the mounting base. A window is formed, and the mounting base is pressed into the window, the tongue is inserted into the recess and the ground plate is combined with the connector body, and the feedthrough capacitor is attached to the hanging part of the contact. And a step of connecting to a ground plate, a method of manufacturing a filter connector device is obtained.

[0009]

The feature of the method of manufacturing the filter connector device of the present invention is that the window portion of the grounding plate works so as to fit the mounting base to arrange the grounding plate in a fixed position, and the tongue piece of the window portion is engaged with the concave portion. It is to work together to prevent the ground plate from coming off the connector.

[0010]

An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an external view of the filter connector device in a completely manufactured state, which is upside down in a used state. FIG.
2A is a vertical side view of the AA line in FIG.
(B) is an exploded perspective view of FIG. 1 for explaining the manufacturing process of the present invention. Insulating connector body 2 of connector 1
Is provided with two mounting bases 3 connected to the back surface on the bottom surface, and steps are formed along the peripheral edge of the rear surface other than the mounting bases 3.

Here, a screw rod insertion hole 31 is formed in the bottom surface of the mounting base 3 by slightly biting into the back wall of the connector main body 2, and a square recess 32 is formed in the front surface of the connector main body 2.
Is formed so as to communicate with the insertion hole 31 along the bottom surface of the. The recess 32 is a cavity for equalizing the wall thickness of each part of the mounting base 3 and facilitating resin molding of the connector 1. Also, a plurality (10 in the figure) bent at right angles
The contacts 4 are provided in the back wall of the connector main body 2 so as to extend vertically in two rows so that the hanging portions 41 have a predetermined arrangement.

A nut insertion hole 5 is formed on the back surface of the connector body 2. Cavities having the same function as the recesses 32 are formed between the rows of the contacts 4 and between the contacts 4 but are not shown.

On the other hand, the ground plate 6 is a rectangular thin conductive plate having a part cut away and a part of the ground terminal 7. The small through holes 8 formed in the ground plate 6 correspond to the arrangement of the hanging parts 41. Also, a rectangular window portion 9 formed on the ground plate 6
Is a size corresponding to the mounting base 3 and fitted. Further, the tongue piece 10 projecting from the window 9 is provided with the concave portion 3 of the mounting base 3.
Corresponds to 2. However, the small through hole 8 has a size smaller than the diameter of the large diameter portion 13 through which the small diameter portion 12 of the feedthrough capacitor 11 (only one is shown in FIG. 2B) can be inserted.

Since such a ground plate 6 is used,
As shown in FIG. 2B, the ground plate 6 is pressed against the connector 1 with the hanging portion 41 facing upward, the tongue piece 10 is slidably contacted with the front surface of the mounting base 3, and the mounting base 3 is windowed. The parts 9 can be fitted together and the tongues 10 can be inserted into the recesses 32 and first assembled into the connector 1 in the temporarily fixed state.

Alternatively, even if the connector 1 is inverted and the arm plate 6 is placed on the lower side, the earth plate 6 is slightly separated from the connector body 2 and the tongue piece 10 is held at the bottom edge of the recess 32. It is stopped and stopped, and is not detached from the connector 1 and detached. Therefore, it is possible to carry out only the work of combining the connector 1 and the ground plate 6 and handle it as a work in process.

Next, the feedthrough capacitor 11 is placed on the ground plate 6 combined with the connector 1, and the hanging portion 41 is passed from the small diameter portion 12 side to the central hole as shown in FIG. Insert it through and attach it. When the feedthrough capacitors 11 are passed through all the hanging parts 41, the state shown in FIG. 1 is obtained. Then, cream solder is applied to a required portion of the feedthrough capacitor 11, and a large soldering iron is applied to a portion of the earth plate 6 which is in contact with the bottom surface of the connector body 2 so that the outer electrode and the earth plate 6 and the inner electrode and the hanging portion. 41 are connected all at once by soldering.

According to the method of manufacturing the filter connector device having such a structure, even if a feedthrough capacitor which does not pass the withstand voltage / capacitance test is generated, as is apparent from FIG. Only a defective product can be pulled out from the hanging portion 41 using a soldering iron, and a non-defective product can be re-inserted for easy replacement.

That is, as shown in FIG. 2A, the length h of the large-diameter portion 13 of the feedthrough capacitor 11 is smaller than the protruding length d of the small-diameter portion 12 from the ground plate 6, and the length of the bottom surface of the ground plate 6 is equal to that of the ground plate 6. It is sufficiently smaller than the spacing z of the bottom surface of the mounting base 3. Therefore, the distance between the feedthrough capacitor 11 and the wiring board is larger than in the conventional case in which the small diameter portion 12 is set to the free end side of the hanging portion 41 using the same ground plate that abuts on the bottom surfaces of the connector 1 and the connector body 2. It is possible not to melt the solder of the feedthrough capacitor 11 when soldering the connector device and the substrate.

[0019]

As described above, in the manufacturing method according to the present invention, the shape of the grounding plate is devised to temporarily fix the grounding plate to the connector, and then the feedthrough capacitor is inserted in the opposite direction to the conventional one. Since the connection is made by soldering, there is an effect that the ground plate and the feedthrough capacitor can be accurately and easily fixed to a predetermined place without using a jig, and the efficiency of the assembling work is improved. Also, because the feedthrough capacitor can be replaced without removing the connector together with the ground plate,
This has the effect of significantly reducing the number of rework steps. further,
Since the feedthrough capacitor can be sufficiently separated from the wiring board,
It also has the effect of improving reliability.
