DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector, and more particularly to a package and a back wiring board (PKG-BW).
The present invention relates to a structure of a package connector for transmitting signals between B).

[0002]

2. Description of the Related Art Conventionally, this type of connector is a PKG-BW
It is used for transmitting signals between B and is composed of a plug connector connected to BWB and a socket connector connected to PKG. FIG. 6 is a sectional view showing a conventional connector. 6, in the plug connector, plug contacts 1 of the same length arranged in a plurality of rows are press-fitted into holes of a plug housing 2 having box-shaped insulation.
It is configured. Further, the socket connector is configured such that a plurality of socket contacts 6 are press-fitted into window holes 4 provided in a plurality of rows in a lattice shape in a socket housing 3 having an insulating property. The socket contact 6 has a contact structure such as a bellows contact, a double-sided contact spring, and a single-sided contact spring.

Next, a method of connecting a plug connector and a socket connector will be described. First, the plug contact 1 is inserted into the window hole 4 so that the plug housing 2 and the socket contact 6 fit together. At this time, the plug contact and the socket connector can be electrically connected by the socket contact 6 having the spring contact structure sandwiching the plug contact 1.

[0004]

However, in this conventional connector, since the socket contact electrically connects the plug connector and the socket connector by sandwiching the plug contact, the outer diameter of the window hole is reduced. Must be formed larger than the outer diameter of the plug contact, which makes it difficult to reduce the pitch between the contacts. In addition, since the L-shaped socket contact is press-fitted from the rear surface of the socket housing, the socket contact is exposed from the socket housing, and the overall length is increased, so that there is a problem that transmission characteristics are deteriorated.

An object of the present invention is to provide a connector which eliminates the above-mentioned drawbacks, can reduce the pitch between contacts, and has little deterioration in transmission characteristics.

[0006]

In order to achieve the above object, a connector according to the present invention comprises a plug housing having an insulating property, and a length for each of a plurality of rows which are press-fitted into holes of the plug housing and arranged in a plurality of rows. A plug connector comprising a plurality of plug contacts having different sizes, a socket housing in which a plurality of rows of window holes into which plug contacts are inserted when mating the connectors are formed in a plurality of rows in a lattice, and a plurality of holes provided in a direction perpendicular to the window holes. And a socket connector having resilient socket contacts which are press-fitted into a plurality of rows and arranged in a plurality of rows.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described in detail with reference to the drawings.

FIG. 1 is a sectional view of a connector showing an embodiment of the present invention. The connector of the present invention includes a plug connector connected to BWB and a socket connector connected to PKG.

In FIG. 1, plug connectors are arranged in a plurality of rows in holes of a box-shaped plug housing 2 having an insulating property, and plug contacts 1 having different lengths for each row are press-fitted in accordance with mating socket connectors. ,It is configured. In addition, the socket housing 3 having an insulating property includes:
Several rows of window holes 4 are formed in a grid pattern so as to correspond to the plug contacts 1, and a plurality of holes 5 are formed in a direction perpendicular to the window holes 4. Socket contacts 6 having different lengths for each row are press-fitted into the holes 5 corresponding to the plug contacts 1 to form a socket connector.

FIG. 2 is a front view showing a plug contact and a socket contact used in the present invention. The tip of the plug contact 1 is tapered and formed so as to be able to be press-fitted to the socket contact 6. The socket contact 6 has an elastic structure made of phosphor bronze metal or the like, such as a bellows contact, and is formed in a substantially S-shape.

Next, a method of connecting the plug contact and the socket contact will be described. First, the plug housing 2 is inserted into the window hole 4. At this time, the plug contact 1 is pressed against the socket contact 6. FIG.
It is a front view showing signs that a plug contact is crimped to a socket contact. Since the socket contact 6 has elasticity, the side that is not crimped to the plug contact 1 is pressed against the wall surface of the hole 5 so that the side to be crimped is curved as shown in FIG. Connected to.

After the crimping, the connector is connected to the BWB and the PKG by a stopper (not shown) provided on the PKG.
And connect.

A socket contact which improves the contact resistance between the plug contact and the socket contact more than the above-described socket contact and enables highly reliable connection will be described below.

FIG. 4 is a front view of a plug contact and a socket contact showing another embodiment of the present invention. In FIG. 4, the socket contact 6 is provided with a slash-shaped introduction part 7 and a through hole 8 at a connection part with the plug contact 1, and plays a role of supporting the plug contact 1 when connecting with the plug contact 1. .

Next, a connection method will be described. FIG.
FIG. 4 is a front view showing a state where a plug contact is connected to a socket contact. While the socket contact 6 shown in FIG. 3 is crimped to the plug contact 1 by bending, the socket contact 6 shown in FIG.
First, the tip of the plug contact 1 is bent by being inserted into the through hole 8 through the slash-like introduction part 7, and the tip of the plug contact 1 is supported on the wall surface of the slash-like introduction part as shown in FIG. The connection is made.

In this type of embodiment, after the connection between the plug contact 1 and the socket contact 6, the connector is connected to the PKG and the B via a stopper provided on the PKG.
WB is electrically connected.

[0017]

As described above, in the connector according to the present invention, since the socket contacts are arranged perpendicularly to the direction in which the plug connector is inserted and are connected by crimping, the outer diameter of the window hole and the outer diameter of the plug contact are provided. And the contact pitch can be reduced. Further, since the socket contact press-fit hole is provided in the socket housing in a direction perpendicular to the window hole into which the plug contact is inserted, the socket contact is not exposed from the socket housing, and the overall length is shortened, so that the transmission characteristics are improved. Further, there is an effect that the miniaturization of the connector can be promoted and the component mounting density of the PKG can be increased.
Further, by providing the slash-like introduction portion and the through hole in the socket contact, the contact resistance with the plug contact can be reduced, and the reliability of the connection can be improved.
