Abstract: An electrical connector of the IDC type having three or more rows of contact members while still enabling sideways installation of mating conductors. The connector is comprised of at least two separate housings, a first housing comprising two rows of cavities disposed longitudinally and adjacent to each other. Each of the cavities is fitted with an electrical contact lug, one extremity of which is shaped for the fastening of a wire conductor, the other extremity being shaped as a contact member. At least one second housing contains at least one row of cavities fitted with contact lugs similar to those in the first housing. The first housing has a shelf member which extends transversely away from a front end. Each of the housings is provided with guiding and locking means to aid in joining, then locking, the housings together. Openings are provided in the shelf member and in the front end of the first housing to enable communication with the contact lugs from locations external of the connector.
