Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cushioning gasket that protects a substrate of an IC (integrated circuit) from vibration and impact and that prevents an adverse radio wave from entering from the outside from adversely affecting the integrated circuit.

[0002]

[Prior art]

 Conventionally, this type of gasket has a cushion body made of elastic material such as urethane or rubber formed in a strip shape, and one side edge of the cushion body is edged by a conductive strip made of a conductive thin metal plate, or the peripheral surface is made flexible. The cushion body is frame-shaped, and the outer peripheral edge of the cushion body is framed by the conductive strip of the conductive metal sheet or the outer circumference of the cushion body. It is used that is provided with a conductive coating portion whose entire surface is covered with a conductive thin metal plate.

[0003]

[Problems to be solved by the device]

 However, the gasket in which the one side edge of the cushion body according to the above-mentioned conventional technique is edged by the conductive strip made of a thin metal plate is often peeled off or damaged, and the entire circumference of the cushion main body is covered. The gasket that encloses the metal sheet with a thin metal plate may impair the cushioning property, and both have a problem that the manufacturing work is troublesome and the cost is high.

[0004]

[Means for solving problems]

 The present invention is intended to solve these problems, and urethane, rubber, or other foam material having elasticity is formed into a strip with an appropriate width, and a conductive material is attached to one side edge portion in the longitudinal direction of the cushion body. A metal thread is sewn at a fine pitch such as overedging or embroidery to provide a conductive strip portion, or the same conductive strip portion is provided on the outer or inner peripheral edge of the cushion body formed in a frame shape. A cushioning gasket is attached to both sides of the board so as to surround the IC board with double-sided adhesive tape to prevent intrusion of interference radio waves that adversely affect the electric circuit of the IC board installed in the electric equipment. The present invention also provides a cushioning gasket that absorbs vibrations and shocks to protect the substrate, and that also prevents intrusion of interference radio waves that facilitates mass production and reduces manufacturing costs.

[0005]

[Effect of the present invention]

 Compared with the conventional gasket of the same kind, the cushioning gasket of the present invention is free from the risk of peeling or damage of the conductive strip portion, and is excellent in the cushioning property and the effect of preventing the intrusion of interference radio waves, and the manufacturing process. However, it has excellent practical effects such as being simple, suitable for mass production, and extremely low in production cost.
