Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric connector having a multi-pole right angle structure for connecting a mother board and a daughter board.

[0002]

2. Description of the Related Art Conventionally, there is a multipolar right angle connector for connecting a mother board and a daughter board.
This connector employs a means for inserting a ground contact between signals as a means for preventing crosstalk that occurs between signals.

Usually, in the electrical connector, the ground contact first comes into contact with the signal contact (live line) in order to protect the equipment system.

The prior art of electrical connectors is as follows:
Japanese Unexamined Patent Publication No. 2-148585 discloses an electric connector.

[0005]

However, it is difficult to adopt this structure in the angle portion as the means for inserting the ground contact between the signals. This is because the angle parts have different lengths in each column, so multiple ground contacts are required to form a structure in which the signal contacts are surrounded by ground contacts, which leads to an increase in the number of parts and a cost increase. ing.

Further, in the electrical connector, since the ground contact comes into contact with the signal contact first in order to protect the equipment system, the end of the ground contact is not contacted with the ground contact when the fitting is completed. Since it is difficult for a current to flow, the effect of the high frequency signal as a ground is weak and there is a problem that ground bounce (change in ground potential) or the like occurs.

Therefore, the object of the present invention is to easily realize a coaxial structure in which the signal contacts are surrounded by the ground even in the angle connector portion, and it is possible to reduce the crosstalk between the signal contacts, which is suitable for high-speed transmission. To provide an electrical connector.

Another object of the present invention is to provide an electrical connector which can be constructed without increasing the number of parts and which is excellent in economic efficiency.

Still another object of the present invention is to provide an electrical connector which can improve the reliability of contact by increasing the contact points of the daughter board and the contact with the ground structure.

Make sure that the bent parts are aligned with the slits at different positions.
An electrical connector is obtained in which the ground contacts are inserted one-on-one and the ground contacts are assembled to the insulator.

[0011]

The crosstalk between the signal contacts, which occurs as the speed of the equipment progresses, is prevented by the contact between the ground contact and the mating ground member, and the ground function is strengthened as a signal return (return) current path.

Further, the first and second ground contact portions are

Only the ground plate part that extends parallel to the contact part
A ground contact portion connected to the mating ground member,
At the position different from the ground contact portion,
Holds in the ground terminal part that extends from the above and the slit
Multiple folds formed on the ground plate so that
The bent portion is inserted into the slit in a one-to-one correspondence
Assemble the ground contact to the insulator
And the connector element is mated at the first and second mounting surfaces.
With each other facing each other and said connector elements being superimposed on each other,
Each of the adjacent ground contacts
The ground terminal parts of are in contact with each other, and the ground contacts are connected by a shield member.
The contact part and the ground contact part are insulated.
Provided in the housing and integrated with the shield member
Electrical connector, characterized in that it is configured to. 4. A mating contact and a mating ground member
Multiple connectors that fit and connect with the mating connector that you have
In an electrical connector including elements, the connector elements are arranged at predetermined intervals in a column direction.
A plurality of conductive signal contacts arranged in a plane,
An insulator holding the signal contact;
With a conductive ground contact assembled to the insulator
And the signal contact is retained in the insulator
Insert the contact so that it contacts the middle part and the mating contact.
A contact portion extending outward from one end surface of the insulator,
Extends from the other end surface of the insulator that is different from the one end surface
The insulator, and the insulator is held so as to sandwich the intermediate portion.
The first and second mounting surfaces facing each other, and the intermediate
A plurality of slits formed in the vicinity of the portion, and the ground contact faces the slits.
Only the ground plate part that extends parallel to the contact part
A ground contact portion connected to the mating ground member,
At the position different from the ground contact portion,
Holds in the ground terminal part that extends from the above and the slit
Multiple folds formed on the ground plate so that
A bent portion , and the bent portion is inserted into the slit in a one-to-one relationship.
At the same time, the ground contact is
The ground contact part is a flat plate-shaped mating ground plate part.
In the mating direction to connect to the mating ground member
The first grans that are formed at positions that are offset from each other
And a second ground contact portion, wherein the first and second ground contact portions are the mating grounds.
The first and second ground contacts when fitted to the plate portion
Part and the plate surface of the mating ground plate part.
And the first ground contact portion is
Cross the plate surfaces of the land plate part and the mating ground plate part.
The second ground contact part is bent forward.
Note that the ground should face the plate surface of the mating ground plate.
The first and second ground contact portions extend from the plate portion and have a leaf spring shape.
The tip of the first ground contact portion is
The first ground contact that comes into contact with the mating ground plate is shaped
And the first and second ground contact portions are plates.
The material is stamped and formed, and the second glass
The tip of the contact part contacts the mating ground plate.
A second ground contact portion is formed, and the first ground contact portion is formed.
If the land contact part is stamped and formed,
The second ground contact part comes into contact with the hand ground plate part.
It is placed so as to come into contact with the mating ground plate part on the material side.
Electrical connectors, characterized by that.
