DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector, and more particularly, to a connector suitable for high-frequency signal transmission and high-density mounting.

[0002]

2. Description of the Related Art With the increase in the density of electronic devices, connectors suitable for high-density mounting, for example, connectors used as packages for mounting LSIs used in these electronic devices have been used. As such a connector, for example, a Land Grid Array (Land Grid Array)
y: LGA). This LGA
In this example, a large number of flat contacts (electrode pads) are formed in an array or the like on the bottom surface of the package.

Conventionally, in such an LGA, a contact whose contact has a beam-like structure having a spring property for contact is used.

[0004]

However, in the case of a conventional connector such as the LGA described above, the contact is
The mechanical requirements for obtaining the required spring properties result in relatively long and narrow shapes. However, when the contact is elongated, the shape of the contact becomes more unfavorable than an ideal shape for transmitting an electric signal.

That is, if the contact has such an elongated shape, particularly when transmitting a high-frequency signal, the inductance becomes large and the contact becomes susceptible to external noise and the like, which causes a problem that the signal deteriorates. there were. Further, since the contact is long, it is difficult to reduce the physical size of the connector, which causes a problem that the size of an electronic device using this type of connector is increased.

An object of the present invention is to provide a connector that can suppress deterioration of a high-frequency signal to a small level and is suitable for high-density mounting.

[0007]

According to the present invention, there is provided a connector comprising: a first side connection object having a first side terminal on one surface;
A second side terminal disposed corresponding to the side terminal, and a second side terminal interposed between the first side connection object and a second side connection object facing the first side connection object in a direction orthogonal to the one surface; A connector for connecting a first-side connection object and the second-side connection object, the connector including an elastomer and a contact, wherein the elastomer extends obliquely with respect to a line parallel to the orthogonal direction. And the contact is elastically supported by the contact holding hole such that both ends protrude from the contact holding hole.

[0008]

Embodiments of the present invention will be described below.

FIG. 1 shows a connector according to an embodiment of the present invention. As shown in FIG. 1, the connector 3 according to the present embodiment includes a first connection object 1 having a first side terminal 1 b on one surface 1 a and a second side arranged corresponding to the first side terminal 1 b. The first side connection object 1 and the second side are interposed between the first side connection object 1 and the second side connection object 2 facing the first side connection object 1 in the direction y orthogonal to the one surface 1a and having the terminal 2b. It is used to connect with the connection target 2. The connector 3 includes an elastomer 31 which is an elastic insulator.
The contact 32 is included.

The elastomer 31 has a contact holding hole 31a extending obliquely to a line segment parallel to the y direction, that is, at an angle larger than 0 ° and smaller than 90 °. The contact 32 has a contact holding hole 3 so that both ends thereof protrude from the contact holding hole 31a.
It is elastically supported by 1a.

As described above, the connector 3 is mounted between the first connection object 1 and the second connection object 2. And the contact 32 is the contact 32
a, 32b are terminals 1b,
2b. In addition, the first side connection object 1, the second
The side connection target 2 is specifically a printed circuit board, a multi-chip module (MCM), an IC, or the like. The terminals 1b and 2b are specifically, for example,
This is a land formed on a printed circuit board.

Next, the operation of the connector 3 of the present embodiment will be described with reference to FIG. First, FIG.
As shown in (a), the contact 32b of the contact 32 is placed on the upper surface of the fixed second side connection object 2 so as to abut the second side terminal 2b. Next, as shown in FIG. 2B, the first connection object 1 located above the connector 3 is pressed against the connector 3 by a force F. Due to this pressing, the contact 32 tends to rotate clockwise in FIG. 2B.

However, since the contact holding holes 31a extend obliquely as described above, the elastomer 31
2B, the distributed load of W acts on the contact 32 in FIG. As a result, a rotational moment acts on the contact 32 in the illustrated direction M, that is, in the counterclockwise direction. Then, the contact 3
2, the first side terminal 1a and the second side terminal 2a are brought into pressure contact with each other.

Of course, in the connector 3 of the present embodiment, the contact holding hole 31a of the elastomer 31 has the longitudinal direction of the contact 32 parallel to the extending direction of the contact holding hole 31a as shown in FIG. And contact 3
2 is inserted.

[0015]

As described above, in the connector of the present invention,
The contact is generated by applying a rotational moment to the contact by utilizing the elasticity of the elastomer, so that it is not necessary to form the contact long and thin in order to provide the contact with a spring property as in the related art. Therefore, the inductance at the contact can be reduced, and the deterioration of the high-frequency signal can be suppressed. Further, since the connector height and the occupied area are suppressed and the physical size can be reduced, the mounting density on a substrate or the like can be increased.
