Apparatus and methods for removing electrostatic charge from a generally non-conductive object that is inserted into a port or receptacle of a housing are disclosed, such as a smart card having an electrostatic charge thereon inserted into a slot of a housing of a smart card reader. Certain ones of the apparatus and methods use a housing including a slot for receiving a generally non-conductive object having an electrostatic charge thereon, and an electrically ungrounded array of protrusions disposed proximate the slot. Selected ones of the protrusions have a sharp tip. The electrostatic charge on the object and the sharp tips generate an electric field that is used to neutralize the electrostatic charge on the object so as to prevent damaging electric shock.

Smart card reader with electrostatic discharge protection

A smart card reader having several advantageous grounding techniques and several techniques to insure proper electrical isolation of the electrical components of the card reader. The smart card reader has a base and a cover. In certain techniques, a non-conductive base is grounded to a conductive, grounded cover. In another technique, a grounded base formed of a statically dissipative composite material is utilized.

Disclosed is a stackable contact system and a contact for use therein. The contact has a tuning fork socket and a cylindrical pin with a bowed compliant middle section for press fitting into a printed circuit board. Multiple contacts are mounted in two insulative housing parts having cavities, apertures and passages for holding the contacts in position. The contact systems may have a printed circuit board sandwiched between them, and multiple layer stacks may be formed.
