Abstract
Described is a substrate connector assembly which includes a first circuit substrate, a second circuit substrate and a connector mounted on the first circuit substrate for connecting wiring patterns formed on the first circuit substrate with wiring patterns formed on the second circuit substrate. The first circuit substrate includes first wiring patterns capable of being connected to external wirings and second wiring patterns in a second wiring area apart from the first wiring patterns by a predetermined creepage distance to provide a sufficient isolation. The connector includes a contact array of a plurality of contacts, and a key which is formed at a position for separating the plurality of contacts of the contact array into a first contact group and a second contact group for (1) preventing a misconnection of the second circuit substrate and (2) separating the first wiring patterns from the second wiring patterns by the predetermined creepage distance. The first contact group is connected to the first wiring patterns and the second contact group is connected to the wiring patterns in the second wiring area.
