Abstract: A connector apparatus which assures sufficient fitting of a pair of connectors with each other. The connector apparatus comprises a pair of connectors and a fixing frame having a through-hole defined by a pair of side walls thereof along which the connectors are movable in a fitting direction and then in a slantwise or inclined direction.
