Abstract
A static charge dissipater for a card slot of an electronic device includes a plurality of filaments on a conductive strip, with tips of the filaments disposed along the slot to induce ionization in the presence of the electrical field of a statically charged card inserted into the slot.
Claims20
An electronic interface component, comprising:
- a slot configured for receiving a second interface component therein, said slot including at least one perimeter member;
- a static charge dissipater attached to said perimeter member, said dissipater including:
- a conductive carrier strip;
- a plurality of electrically conductive filaments electrically connected to said conductive carrier strip, said filaments having distal tips in spaced relation to said conductive carrier strip;
- and
- an adhesive for connecting said strip and said filaments to said perimeter member;
- and
- said dissipater positioned on said perimeter member with said filament distal tips in substantially uniform position relative to a said second interface component inserted into said slot.

A static charge dissipating assembly for an electronic component card slot, said static charge dissipating assembly comprising:
- at least one perimeter member defining said card slot for receiving a card inserted therein in an insertion direction;
- and
- a static control device attached to said perimeter member, said static control device including;
- a conductive plastic carrier strip, said carrier strip having a length and first and second lateral edges, said carrier strip disposed transverse to said insertion direction;
- and
- a plurality of electrically conductive filaments attached to said carrier strip, said plurality of filaments disposed on said strip transverse to said lateral edges, and extending beyond at least one of said lateral edges, said filaments having diameters sufficiently small to induce ionization in the presence of an electrical field, and having distal ends remote from said carrier strip disposed in said slot.

A method for dissipating static charge on a card inserted into a card slot of an electronic device, said method comprising steps of:
- providing a path for inserting the card in to the slot, and an arrangement of filaments having diameters sufficiently small to induce ionization in the presence of an electrical field;
- positioning distal ends of the filaments in the path;
- passing the card along the path adjacent the distal tips of the filaments;
- and
- inducing ionization from the static electric charge on the card passing along the filament distal tips.
