Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a connector suitable for a high frequency transmission system.

[0002]

2. Description of the Related Art Conventionally, as a connector of this type, a plug in which a metal socket is integrally mounted in a synthetic resin body and a metal pin in a synthetic resin body are integrally mounted. It is known that each socket of these plugs and each corresponding pin of the receptacle are detachable.

Such a connector is disclosed in, for example, Japanese Unexamined Patent Publication No.
As described in Japanese Patent No. 281,359, a connecting device (interface connector) for connecting a plurality of printed circuit boards equipped with a CPU (central processing unit) via a bus.
Is used as.

However, with the increase in the speed of the CPU clock, a signal inducing failure occurs between adjacent signal lines, that is, a failure in which signals influence each other due to electromagnetic induction between adjacent signal lines.

[0005]

However, since the conventional connector has a structure in which the sockets or pins are integrally attached to the main body made of synthetic resin as described above, the sockets and the pins forming the signal path are connected to each other. In between, it is electrically insulated from each other sufficiently by the synthetic resin body,
No consideration has been given to mutual electromagnetic shielding. As a result, especially in a high-frequency transmission system, signal inductive interference between adjacent sockets or pins at a narrow interval cannot be ignored, and the conventional connector has a limit in its usable frequency.

Therefore, an object of the present invention is to provide a connector which prevents signal inductive interference between adjacent sockets and pins and can be practically used even in a transmission line for high frequency transmission.

[0007]

In order to achieve the above object, the present invention has the following constitution.

In the plug of the present invention, a plurality of socket mounting holes are formed in the plug main body made of a conductor, and the socket is inserted with an insulator interposed in each socket mounting hole.

In the receptacle of the present invention, a plurality of pin mounting holes are formed in the receptacle main body made of a conductor, and the pins are inserted through the pin mounting holes with an insulator interposed therebetween.

Further, in the connector of the present invention, a plurality of socket mounting holes are bored in a plug main body made of a conductor, and a receptacle made of a conductor and a plug in which a socket is inserted with an insulator interposed in each socket mounting hole. The main body consists of a plurality of pin mounting holes, and receptacles in which pins are inserted with an insulator interposed in each pin mounting hole, so that each socket of the plug and each corresponding pin of the receptacle can be freely attached and detached. It was formed.

[0011]

As described above, according to the plug of the present invention, a plurality of socket mounting holes are formed in the plug main body made of a conductor, and the socket is inserted with an insulator interposed in each of the socket mounting holes. By the body, each socket is individually electromagnetically shielded. Therefore, each socket forming the signal path can prevent a signal inductive interference with an adjacent socket, and can prevent the influence of external noise.

Further, according to the receptacle of the present invention, a plurality of pin mounting holes are formed in the receptacle main body made of a conductor, and the pins are inserted into each of the pin mounting holes with an insulator interposed therebetween. Causes each pin to be individually electromagnetically shielded. Therefore, each pin can prevent an inductive interference of a signal with an adjacent pin and can prevent an influence of external noise.

Further, since the connector of the present invention comprises the above-mentioned plug and receptacle, both of them are mounted and used. At the time of mounting, the corresponding socket and pin are connected, but since each connection part is also electromagnetically shielded by the conductor, it is possible to prevent signal inductive interference with the adjacent connection part and also to prevent the influence of external noise. It can be prevented.

Therefore, each of the pins 16 forming the signal path can prevent a signal inductive interference with the adjacent pin 16 and can prevent the influence of external noise.

Further, since the insertion portion 21 of the pin 16 of the receptacle 2 is inserted and connected to the pin receiver 11 of the socket 4 of the plug 1, each of these connection portions is made of a conductor via the insulating layer 9. Electromagnetic shielding is performed by the plug body 3 individually. Therefore, each of the connecting portions forming the signal path can prevent a signal inductive interference with the adjacent connecting portion, and can prevent the influence of external noise.

The connector of the present invention is suitable as an interface connector that requires high-speed transmission, but other than that, a connector between devices that requires high-speed transmission, a connector for connecting printed boards up and down, and a high-speed connector.
