BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector used for electronic equipment or the like for connecting a ribbon-shaped connecting electric wire.

[0002]

2. Description of the Related Art Some electronic devices dislike mutual interference between a plurality of signal lines of connecting electric wires. A conventional connector is a plan view in FIGS. 7A, 7B and 7C, and B- in FIG.
It was as shown in the sectional view and the bottom view along line B. Reference numeral 1 denotes a ribbon-shaped connecting electric wire in which a signal wire 3 and a ground wire 4 are alternately arranged in a width direction on an insulating coating 2 having a ribbon shape. Reference numeral 5 is a base made of a synthetic resin molded product, on which the connecting electric wire 1 is pressed. Reference numeral 6 denotes a plurality of signal connection pieces embedded in the base body 5 in a vertical direction at positions corresponding to the respective signal lines 3.

A side view of the signal connecting piece 6 is shown in FIG. Reference numeral 7 denotes a plurality of ground contact pieces embedded in the base body 5 in a vertical direction at positions corresponding to the respective ground lines 4. The sandwiching contact portions 7a project from the top surface of the base body 5, and the tips of the contact pin portions 7b are the base bodies 5. It projects from the bottom surface. A side view of the ground contact piece 7 is shown in FIG. 8 (B). As shown in FIG. 7C, each signal contact pin portion 6 of the connector
b is arranged adjacent to the base body 5 in the X-axis direction, and each ground contact pin portion 7b is arranged adjacent to the base body 5 in the Y-axis direction with respect to the signal contact pin portion 6b and adjacent to the base body 5 in the X-axis direction. Has been done. S indicates the position of the signal contact pin portion 6b, and E indicates the position of the ground contact pin portion 7. Reference numeral 8 denotes an insulating cover for covering the connection electric wire 1 pressed onto the upper surface of the base 5, which is detachably locked to both ends of the base 5.

The connecting electric wire 1 is provided on the upper surface of the base body 5 of the connector.
When is pressed, the sandwiching contact portion 6a of each signal connecting piece 6 pierces the insulating coating 2 at its tip and presses the corresponding signal line 3 into pressure contact. At the same time, the sandwiching contact piece 7 of each grounding connection piece 7
The tip of a penetrates the insulating coating 2 at its tip, and press-contacts the corresponding ground wire 4. The signal contact pin portions 6b and the ground contact pin portions 7b are inserted and connected to female contact pin portions of a connector (not shown) for connection.

In the above-mentioned conventional connector, the ribbon-like connecting electric wire 1 has the signal lines 3 and the ground lines 4 arranged alternately.

In order to prevent this, as another conventional connector, as shown in a plan view in FIGS. 9A, 9B and 9B, a sectional view taken along the line BB in FIG. 9A and a bottom view. There is a way to do it. The adjacent pin portions of all the signal contact pin portions 6b are arranged so as to be the ground contact pin portions 7b. For this purpose, as shown in FIG. 9B, it is necessary to use the signal connecting piece 6 and the grounding connecting piece 7 which are adjacent to each other in the X-axis direction. However, according to this, there is a place where the gap t between the adjacent sandwiching contact portions 6a and 7a is small.

[0006]

The conventional connector described above has a problem that the signal contact pin portions 6b are arranged adjacent to each other in the connector of FIG. 7, and mutual interference of signals is not sufficiently eliminated. Further, in the case of FIG. 9, there is a problem that there is a portion where the gap between the adjacent sandwiching contact portions 6a and 7a is insufficient.

The present invention has been made in order to solve the above problems, and an object thereof is to obtain a connector in which mutual interference of signals between signal contact pin portions is surely eliminated inside the base body. .

In the connector according to the present invention, in the first invention, the adjacent signal contact pin portions are arranged diagonally to increase the distance, and the signal contact pin portion and the ground contact pin portion are connected to each other. Are alternately arranged in the X- and Y-axis directions, and the signal sandwiching contact portion and the ground sandwiching contact portion which are adjacent to each other in the X-axis direction are displaced in the Y-axis direction to increase the distance.

In the second invention, the signal contact pin portions and the ground contact pin portions are alternately arranged in the X and Y axis directions,
The ground contact pin portions are connected by a conductor.

[0010]

In this invention, in the first invention, the distance between adjacent signal contact pin portions is increased diagonally, and the signal contact pin portions and the ground contact pin portions are arranged alternately in the X and Y axis directions. Therefore, mutual interference elimination of signals is sufficient. Further, in the second aspect of the invention, the adjacent ground contact pin portions are connected by the conductors, so that mutual interference elimination of signals is further improved.
