A connector structure has a second connector fitted to an interior of a cylindrical receiving port of a first connector such that the first and second connectors can be electrically connected together in an inner region of the cylindrical receiving port. A fitting portion of the second connector exhibits a generally square configuration, four corner portions of the square fitting portion are each defined as an arcuate corner portion arranged on an inscribed circle of the cylindrical receiving port and having the same radius of curvature as the inscribed circle, an arcuate surface of each of the four arcuate corner portions is in inscribed relation to an inner peripheral surface of the cylindrical receiving port, and four side portions between adjacent arcuate corner portions are located away from the inner peripheral surface of the cylindrical receiving port.
A connector structure comprising a first connector including a cylindrical receiving port, and a second connector including a generally square fitting portion, wherein said second connector is fitted to an interior of said cylindrical receiving port of said first connector such that said first and second connectors can be electrically connected together in an inner region of said cylindrical receiving port, wherein four corner portions of said square fitting portion are each defined as an arcuate corner portion arranged on an inscribed circle of said cylindrical receiving port and having a same radius of curvature as said inscribed circle, wherein an arcuate surface of each of said four arcuate corner portions is in inscribed relation to an inner peripheral surface of said cylindrical receiving port, and wherein four side portions between adjacent arcuate corner portions are located away from the inner peripheral surface of said cylindrical receiving port.
A connector structure comprising a first connector including a cylindrical receiving port, and a second connector including a fitting portion, wherein said second connector is fitted to an interior of said cylindrical receiving port of said first connector such that said first and second connectors can be electrically connected together in an inner region of said cylindrical receiving port, wherein a plurality of slits extending axially and reaching an end face of said receiving port are circumferentially spacedly formed in a peripheral surface of said cylindrical receiving port so as to define a plurality of receiving port component pieces therebetween, wherein a locking projection projecting inwardly is formed on an inner peripheral surface of an end portion of each of said receiving port component pieces divided by said slits, a fitting portion of said second connector is movable into abutment with said inwardly projecting locking portion of each of said receiving port component pieces to dilate said receiving port component pieces and is fittable to an interior of said cylindrical receiving port such that said receiving port component pieces are closed by a tail end of said fitting portion so that said inwardly projecting locking projection is locked to said fitting portion, and wherein a dilation preventive member is axially movably fitted to an outer peripheral surface of said cylindrical receiving port for movement between a dilation preventing position and a dilation allowing position such that dilation of said receiving port component pieces is prevented when said dilation preventive member is moved axially to said dilation preventing position, thereby retaining a connected relation between said first connector and said second connector.
