[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a board-to-board connector for connecting boards.

[0002]

2. Description of the Related Art FIG. 8 is a cross-sectional view of an example of a conventional connector for connecting boards, and FIG. 9 is a cross-sectional view of another example of a conventional connector for connecting boards. Referring to FIGS. 8 and 9, a connector for a conventional inter-board connection is between the second substrate 5 having a first substrate 3 having a first contact pad 2 a second contact pad 4 A housing 1 disposed between the housing 1 and the housing 1
And a contact 10 having a first contact portion 13 that contacts the first contact pad 2 and a second contact portion 14 that contacts the second contact pad 4.

FIG. 8A shows a connector for connection between boards before connection, and FIG. 8B shows a connector for connection between boards after connection. In the case of the connector for connection between boards shown in FIG. 8, the contact 10 includes a first contact portion 13 and a second contact portion 14.
Has a substantially U-shaped elastic portion 40 for pressing against the first contact pad 2 and the second contact pad 4, respectively. And the second contact pad 4 are connected.

On the other hand, in the case of the connector for connection between boards shown in FIG. 9, the contact 10 has a substantially W shape, and has a tongue piece 50 at one end and a tongue piece 51 at the other end. doing. These tongues 50, 51 are in sliding contact with the central bent portion 52 of the contact 10, and accordingly, the tongues 50, 51
The first contact pad 2 and the second
Is linearly connected to the contact pad 4 of the first embodiment.

[0005]

There is a trend toward digitization and high-speed processing in electronic devices. For this reason, it is required that a conductive path in a circuit be as short as possible. However, in the connector shown in FIG. 8, in order to generate a stable contact force on the contact 10, it is desirable that the elastic portion 40 is large, so that the first contact pad 2 and the second contact pad 4 However, there is a disadvantage that the conductive path for connecting the electrodes is inevitably elongated.

On the other hand, in the connector shown in FIG.
The first contact pad 2 and the second contact pad 4 are linearly connected by the 0, 51 and the central bent portion 52, so that the conductive path is shortened. However, in this conductive path, between the tongue 50 and the central bend 52 and tongue 51
Since there is a sliding contact portion between the central bent portion 52 and the center bent portion 52, there are disadvantages such as an increase in contact resistance and a decrease in reliability.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a board-to-board connector which can connect two boards in a shortest and reliable manner.

A connector for connection between boards is obtained in which the other contact portion is pressed against the corresponding contact pad by a repulsive force .

According to connector between substrates according to claim 2, wherein the connection housing which is disposed between the second substrate having a first substrate and a second contact pad having a first contact pad And a contact provided in the housing and having a first contact portion that contacts the first contact pad and a second contact portion that contacts the second contact pad. the connector, the contact is a substantially one straight line has the first contact portion and the second contact portion on the other end has at one end, and said first and second contact portions one of the contact portion is provided in the housing so as to freely rotate around the other contact portion of the inner, further
And between the contact and the housing, the contact is urged, and the one contact portion is correspondingly urged.
A repulsive force when Rutotomoni the pressing to contact pads that
A connector for board-to-board connection characterized in that a biasing body for pressing the other contact portion against the corresponding contact pad is provided in the housing.

[0010]

In the case of the connector for connection between boards according to claim 1,
When the connector is arranged between the first substrate and the second substrate, the first contact portion of the conductive portion contacts the first contact pad of the first substrate with the second contact portion of the conductive portion. The portions are pressed by the second contact pads of the second substrate, respectively, and the second contact portion rotates about the first contact portion. With the rotation of the second contact portion, a force for urging the conductive portion is generated in the urging portion. Accordingly, the second contact portion tends to rotate around the first contact portion toward the second contact pad.
As a result, the second contact portion of the conductive portion becomes the second contact portion of the second substrate.
Make sure to contact the contact pad. On the other hand, due to the repulsive force when the second contact portion is pressed against the second contact pad by the urging portion, the first contact portion is also pressed against the first contact pad and surely contacts. As a result, the first contact pad of the first substrate and the second contact pad of the second substrate are reliably connected by the linear conductive portion of the contact, so that the first contact pad is provided. The conductive path between the pad and the second contact pad is short.

[0011] In the case of the connector for inter-board connection according to claim 2, when the connector is arranged between the first board and the second board, the first contact portion of the contact is formed on the first board. The first contact pad has a second contact portion of the contact,
The second contact portions are pressed by the second contact pads of the second substrate, respectively, and the second contact portions rotate about the first contact portions. With the rotation of the second contact portion, a force for urging the contact to the urging body is generated. Accordingly, the second contact portion tends to rotate around the first contact portion toward the second contact pad. As a result, the second contact portion of the contact surely contacts the second contact pad of the second substrate. On the other hand, by the repulsion force when the second contact portion is pressed against the second contact pad by the biasing body, the first contact portion also
The first contact pad is pressed to make sure contact. As a result, since the first contact pad of the first substrate and the second contact pad of the second substrate are securely connected by the linear contact, the first contact pad and the second contact pad are securely connected to each other. The conductive path between the two contact pads is short.

Further, since the first contact portion 13 of the conductive portion 11 is rotatably held by the opening 7, when the housing 1 is disposed between the first substrate 3 and the second substrate 5, When the first contact portion 13 is pressed by the first contact pad 2 and the second contact portion 14 is pressed by the second contact pad 4, the second contact portion 14 It rotates around the contact portion 13. As a result, the distance a1 between the conductive portion 11 and the lower end portion of the urging portion 12 before the connector shown in FIG. 1 is disposed between the substrates 3 and 5 is reduced to a2 as shown in FIG. As a result, a stronger urging force is generated in the urging portion 12, and the second contact portion 14 is pressed against the second contact pad 4 by the urging force and connected. In addition, the first contact portion 13 is pressed by the first contact pad 2 and connected by the repulsive force of the pressing force at this time. As a result, the first contact pads 2 of the first substrate 3 and the second contact pads 4 of the second substrate 5 are connected linearly and reliably by the conductive portions 11 of the contacts 10. You.
