Abstract

An electrical connector assembly includes a cassette and a receptacle electrically and mechanically coupled together. The cassette includes a housing encompassing a printed circuit board and a plurality of electrical contacts in connection with terminals on the circuit board and disposed at a bottom surface of the cassette housing for exterior connection thereto. The receptacle includes a housing having a cavity for receipt of the cassette therein. The cavity is of size to accommodate rotation of the cassette in the cavity from an insertion position to a latched position. The receptacle housing includes a plurality of spring contacts adjacent the bottom of the cavity, the spring contacts being electrically engaged by the contacts on the cassette upon insertion of the cassette into the receptacle cavity. The receptacle housing includes a pair of spaced opposing pins projecting into the cavity that enter and engage slots formed on the lower sides of the cassette. These pins and slots provide a stop surface to prevent overstressing the spring contacts during insertion and rotation of the cassette and also provide a pivot on which the cassette is rotated from the insertion position to the latched position.
