Abstract
A dust cover for a ZF connector utilizes a three part, layered gasket for both wiping an inserted board and sealing the connector when the board is withdrawn. A first layer is a flexible, woven material, a second layer is a flexible, non-woven material, e.g., rubber, and the third layer is a rigid material including a slot to accommodate an inserted board as well as displaced material from the first two layers.
Claims5
A dust cover for a printed circuit board card connector, said dust cover comprising:
- an elongated body having a top surface;
- four depending walls attached to said top surface and defining a hollow space formed to receive a printed circuit board card connector;
- engaging means attached to at least one of said walls and formed to cooperate with said printed circuit board card connector for retaining said dust cover in position thereon;
- an elongated, printed circuit board receiving slot substantially centrally formed in said top surface;
- and
- a sealing gasket attached to the underside of said top surface within said hollow space, said sealing gasket being formed from a flexible material and having a longitudinal slit formed therein, said slit being substantially aligned with the center of said slot, said gasket comprising a laminated member of first and second dissimilar, flexible materials each having a slit.
