Abstract
ABSTRACT
A connector comprises a series of slotted terminals integrally joined to a carrier strip mounted in an insulating housing with the carrier strip extending through slots formed in barrier walls separating adjacent terminal-receiving cavities so that insulated wires can be inserted simultaneously through a wire-receiving face of the housing into the slotted terminals and thereby connected together.
