DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a terminal connection structure of a storage device for electrically connecting or disconnecting terminals provided on one side of the storage device by inserting and extracting the storage device.

[0002]

2. Description of the Related Art In recent years, digital cameras and digital videos have become extremely popular. As an example of a digital data storage device of such a device, a solid, generally rectangular, rectangular solid having a relatively thin thickness, which is generally covered with resin and has no movable parts, has become widespread. And this storage device is provided with a plurality of terminals on one wide side,
Each terminal is appropriately electrically connected to a solid-state memory circuit or the like provided in the device.

An example of a conventional terminal structure of a storage device having such an external shape is proposed in Japanese Utility Model Laid-Open No. 5-59774. According to this technique, a contact piece made of a conductive plate is provided on a lever part that swings when one end is pressed by the insertion of a storage device, and this contact piece elastically contacts a terminal. The contact piece is formed of a spring member so as to elastically contact the terminal with a predetermined elasticity.

[0004]

In the above-mentioned prior art, when one end of the lever portion with which the inserted storage device comes into contact wears, the force with which the contact piece elastically contacts the terminal is likely to change. Further, in order for the contact portion to resiliently contact the terminal with a predetermined elasticity, the contact portion must start contacting the storage device before the swing of the lever portion ends. This requires the storage device to be moved in the insertion direction with the contact pieces in contact with each other, and the contact pieces and the terminals are relatively displaced, causing wear. Therefore, the durability life of the storage device against insertion and removal is not always sufficient.

SUMMARY OF THE INVENTION The present invention has been made to improve the prior art described above, and it is an object of the present invention to provide a terminal connection structure for a storage device which has a long durability life with respect to insertion and extraction of the storage device without causing terminal wear. Aim.

[0006]

In order to achieve the above object, a terminal connection structure of a storage device according to the present invention is configured such that a storage device provided with terminals on one side can be freely inserted into and removed from a storage holder. The one side provided with the terminals of the inserted storage device, which is arranged to be swingable on a frame by an axis parallel to the one side surface and orthogonal to the insertion direction on the front side where the storage device is inserted. On the opposite side, a push-up spring that pushes up the storage holder by elasticity is provided on the frame, and a pressing slider that presses at the tip of the storage device and moves in the insertion direction with the insertion of the storage device is provided on the insertion tip side of the frame. By moving the pressing slider in the insertion direction, the insertion tip side of the storage holder is pressed down against the elasticity of the push-up spring, and the storage holder is pressed down. In configured to provide a spring connector to elastically contact with the terminals of the storage device.
