Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to the structure of a connector.

0002

[Conventional technology]

Conventionally, the connectors attached to the video equipment of electrical products are as shown in Figure 3. 21 forms a cylindrical protrusion 24 having an insertion hole 23 on one side of the insulator 22; A terminal chamber 25 is provided at the back of the protruding part 24, and is provided around the outside of the protruding part 24. A ground terminal 26 is provided that passes through the chamber 25 and projects from the insulator 22 to the outside, and further , the terminal chamber 25 at the back of the insertion hole 23 has a diameter smaller than that of the insertion hole 23, and the end A signal terminal 27 is provided that passes through the child chamber 25 and protrudes from the insulator 22 to the outside. Connect the signal terminal 27 and ground terminal 26 to an electrical circuit provided on a printed circuit board, etc. are emotionally connected.

0003 According to the above configuration, when the video equipment is put into the receiving state, the plug is inserted into the connector 21. When not connected, the signal terminal 27 and the ground terminal 26 are always separated. This makes it easier to pick up unnecessary signals such as noise and interference signals, and therefore On the other hand, problems such as S/N and crosstalk occur, which tend to deteriorate video characteristics. It had a problem.

[Problem that the idea aims to solve]

This invention was developed in view of the above problems, and eliminates unnecessary signals such as noise and interference signals. Provides a connector structure that prevents intrusion into electrical circuits through connector terminals. do.

[0005]

[Means to solve the problem]

In order to solve the above problems, the present invention provides a connector equipped with a signal terminal and a ground terminal. The signal terminal is equipped with a tongue piece that contacts the ground terminal at the back of the insertion hole. It consists of a long-shaped connector, and the connecting pin of the plug is inserted into the insertion hole of the connector. When the connection pin separates the tongue piece from the ground terminal, and It is characterized in that the pin and the signal terminal are electrically connected.

[0006]

[Effect]

According to the above configuration, the tongue piece of the signal terminal contacts the ground terminal in the insertion hole of the connector. When the connecting pin of the plug is inserted into the insertion hole, the connecting pin The tongue piece is separated from the ground terminal by the pin, and the connecting pin and the signal Connect electrically between terminals.

【Example】

Hereinafter, one embodiment of the present invention will be described based on the drawings. The connector that is attached to the video equipment of electrical products has a connector as shown in the cross-sectional view of the main part shown in Figure 1. The connector 1 has a cylindrical protrusion 4 having an insertion hole 3 formed on one side of the insulator 2. A terminal chamber 5 is provided at the back of the portion 4, and is provided around the outside of the protruding portion 4. A ground terminal 6 is arranged to protrude from the insulator 2 to the outside through the insertion hole 3. The insertion hole 3 is inclined toward the entrance direction from the entrance direction of the insertion hole 3, and the tip is bent toward the back. It is provided with a tongue piece 7 whose tip touches the ground terminal 6 of the terminal chamber 5 across the tongue piece 7. A signal terminal 8 is provided that connects and passes through the terminal chamber 5 and protrudes from the insulator 2 to the outside. are doing. Then, the signal terminal 8 and the ground terminal are connected to an electric circuit provided on a printed circuit board (not shown), etc. It is electrically connected to child 6.

[0008] In the above configuration, when inserting the plug 9 to be connected to the connector 1, refer to Figure 2. As shown in the main part sectional view, the plug 9 is connected to the ground terminal 6 provided around the outside of the protrusion 4. At the same time, insert the connecting pin 11 provided at the center of the plug 9 into the insertion hole 3. When the connecting pin 11 is inserted into the Push up the tongue piece 7 that is in contact with the terminal 6 in the inclined direction, and remove the tongue piece 7 from the ground terminal 6. Separate to cut off the electrical connection between the tongue piece 7 and the ground terminal 6, and connect the connecting pin 11 and the signal. The terminals 8 are electrically connected. Therefore, when the video equipment is in the receiving state, insert the connecting pin 11 into the insertion hole 3. If not, the tongue piece 7 and the signal terminal 8 are electrically connected, and the insertion hole 3 is connected to other electrical terminals. When connecting pin 11 from an electrical product is inserted, the signal from the electrical circuit of another electrical product is This allows unwanted signals such as noise and interference signals to be removed from electrical circuits. It is possible to prevent the intrusion into the computer and also prevent the deterioration of the video characteristics of the device. It is something. The material used for the tongue piece 7 is nickel metal if compared to elastic phosphor bronze. It is formed using a plated material.

[0009]

[Effect of the idea]

As mentioned above, this invention has a signal terminal that contacts the ground terminal in the insertion hole of the connector. The tongue piece prevents noise and interference even when the plug is not inserted into the connector. Prevents unwanted signals such as harmful signals from transmitting through the connector terminals and entering the electrical circuit. It has the advantage of being able to
