Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector such as a package connector suitable for connecting to a substrate or the like and transmitting an electric signal, and more particularly to a connector having excellent noise characteristics.

[0002]

2. Description of the Related Art FIG. 4 shows an example of a conventionally used connector. The left side of this figure shows the plug connector 12 attached to the substrate 11. The plug connector 12 has a structure in which plug contacts 14 are press-fitted into a bottom portion of an insulator body 13 having a U-shaped cross section over a plurality of rows.

The right side of the figure shows a socket connector 17 connected to another board 16. Socket connector 17
The socket contact 21 is press-fitted into a large-diameter cylindrical hole portion in the insulator body 19 having the plurality of holes 18. When the socket connector 17 is inserted into the plug connector 12, the plug connector 12 comes into electrical contact with the socket contact 21. The other ends of the socket contacts 21 are connected to the board 16, respectively.

In the conventional connector shown in FIG. 4, the socket contacts 21 are separated from each other only by the insulator body 19. Recently, as electronic devices have become more sophisticated, the types of electrical signals have increased significantly, and the density of parts and the speed of signals have been increasing. Therefore, the electrical characteristics of the connector have become a problem, and in particular, there is a problem that crosstalk between contacts is large. In addition, from the insulator body 19 of the socket connector 17 to the socket contact 21.
Although it is exposed, there was a problem that the electrical characteristics deteriorated in this part. In addition, the ground may be incomplete with only the ground pin connected to the ground,
There was also a problem that noise was generated from the connector part.

Therefore, for example, in Japanese Utility Model Laid-Open No. 3-12367, a shield layer for shielding each contact of a multipolar connector and an insulating layer for insulating the shield layer from the contact are provided for each contact. is suggesting. Further, in JP-A-2-223172, a cylindrical ground contact is arranged so as to individually surround each of a large number of signal contacts, and this covers the entire circumference of the contacts, thereby effectively preventing the occurrence of crosstalk. is doing.

[0006]

However, in these proposals, the shield layer and the insulating layer are covered for each contact, or the cylindrical ground contact is surrounded by each contact, so that the structure is complicated, There was a problem that the manufacturing cost was considerably high. Further, because of the structure that covers or surrounds the contacts, it is difficult to arrange the contacts at high density, and there is a problem that the connector becomes large.

Therefore, an object of the present invention is to provide a connector which has good electrical characteristics and is easy to manufacture.

According to a first aspect of the present invention, there is provided (a) a box-shaped plug-side insulator body, a plug-side metal plate disposed on an inner surface of the plug-side insulator body, and the plug. A plug connector consisting of plug contacts planted in several rows at the bottom of the side insulator body, a socket-side insulator body having its tip fitted to a (b) box-type plug-side insulator body, and this socket The socket contacts arranged in the holes provided at the positions corresponding to the plug contacts in the side insulator body, and parallel to the surfaces forming the respective rows of these socket contacts, between these rows and at the outermost side. The connector is provided with a socket connector including a socket-side metal plate arranged on each outside of the row.

That is, according to the first aspect of the present invention, the metal plate on the plug side is arranged on the inner surface of the box-shaped plug connector, while the socket connector has sockets between each row of socket contacts and on the outer side of each outermost row. The side metal plate is placed to reduce the occurrence of crosstalk between rows.

According to the second aspect of the present invention, the socket side metal plate is provided not only on the socket side insulator, but also between each example of the contacts drawn out from the outside and on the outside of the outermost row. It shows that they can be arranged consecutively. This is effective in improving the electrical characteristics in the parts other than the insulator.

According to the third aspect of the invention, it is shown that the plug-side metal plate and the socket-side metal plate can be electrically contacted and grounded when the connector is connected. As a result, the ground can be strengthened.
