Abstract
A connector for connecting internal circuitry of a bar code scanner to a connector plug. One end of a contact assembly is used together with a scanner chassis to form a receptacle for receiving the plug. The other end of the contact assembly connects with the internal circuitry. The contact assembly includes a plurality of wires with a ground wire that is bent to contact a scanner casing upon insertion of the contact assembly into the scanner casing. Two or more of the wires have lateral protrusions extending toward each other to provide points at which arcing is most likely in the event of an increased surge of current. One of the wires with the protrusions is also the wire that is bent outward so that any arcing is grounded to the scanner casing.
