[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector used for connecting between boards constituting electronic equipment.

[0002]

2. Description of the Related Art Conventionally, in electronic equipment, a connector for mechanically connecting a plurality of substrates to each other and electrically connecting them has been used. The structure shown in FIG. 5 is known. The connector shown in this figure is for connecting a mother board 1 as a board to a daughter card 2 as another board, and is constituted by a female connector 3 mounted on the mother board 1. Has a fitting hole formed in a direction orthogonal to the mother board 1, and a fitting portion formed in the male connector 4 along the surface direction of the daughter card 2 so as to fit both connectors 3 and 4 together. As a result, the daughter card 2 is connected so as to be orthogonal to the mother board 1.

[0003]

By the way, in such a conventional connector, as shown in FIG. 6, for example, the connection pin 5 provided on the male connector 4 is perpendicular to the daughter card 2. After being raised in the direction, the daughter card 2 is bent along the surface direction. However, such a shape of the connecting pin 5 causes the following problems to be improved. That is, if the bent shape as described above,
As a result, the connection pin itself becomes long and the number of relay points increases, which hinders high-speed signal transmission and is susceptible to noise. Furthermore, in recent years, in order to support high-density mounting, the number of pins of the connector has been increasing, and accordingly, the force required for connecting and disconnecting the connector is large, and the operability when attaching and detaching the connector is poor. There are also problems.

The present invention has been made in view of such conventional problems, and a first object thereof is to provide a connector capable of shortening the length of a connecting member such as a connecting pin as much as possible. A second object is to provide a connector that can be attached and detached with a small force.
