Abstract
Abstract A multi-contact connector assembly for electrically connecting a plurality of electrical conductors such as insulation clad wires to an electrical device such as, for example, a printed circuit board. The multi-contact type connector includes an open top housing for enabling a number of the contacts to be accommodated therein. Each of the contacts includes a connecting section enabling an electrical connection with the printed circuit board and a wire holding section in which the insulation clad wire is held in an electrically conductive manner to the respective contacts. The wire holding section includes first and second walls having aligned slots therein, with a construction being provided for preventing the first slotted wall from bending sideways or laterally when the insulation clad wire is inserted into the slot therein. A housing is provided which includes additional slots aligned with the first and second slots, with the additional slots being disposed in the rear wall of a housing and accommodating the insulation clad wire. Further openings are provided in the front wall of the housing for enabling the connecting sections to extend therethrough.
