1. An electrical terminal connector for electrically and mechanically connecting a pair of parallel insulated electrical conductors, comprising a. a deformable generally trough-shaped electrically conductive ferrule (1) including generally planar horizontal base (3) and vertical side wall (2) portions, 1. one of said base and side wall portions containing intermediate its ends a pair of laterally-spaced inwardly directed insulation piercing means (4a, 4b) for piercing the insulation of said conductors, respectively, when said conductors are arranged longitudinally in said ferrule, thereby to establish electrical connection between said ferrule and the conductive cores of said conductors; 2. the other of said base and side wall portions containing intermediate its ends a pair of inwardly directed conductor engaging means each consisting of a group of inwardly directed protrusions (5) arranged laterally of and directly opposite said piercing means for engaging the outer surfaces of said conductors, respectively, the protrusions of each group being so arranged that the associated conductor is held captive therebetween, said piercing means being arranged solely on said one of said base and side wall portions and said conductor engaging means being arranged solely on the other of said base and side wall portions; 3. each of said side wall portions containing at its upper edge (11) a clearance recess (7) that defines a pair of upper edge portions arranged at opposite ends of said side wall portion, respectiVely; 4. said side wall portions having such a height as to permit them to be progressively crimped inwardly together upon the upper surfaces of said conductors and downwardly between said conductors, thereby to cause said conductor engaging means to hold the respective conductors captive and to force said conductors into piercing engagement with said insulation piercing means; and b. a trough-shaped cover of insulating material (9) arranged about the external surface of said ferrule, said cover having base and side wall portions contiguous with the corresponding portions of said ferrule, respectively, the side wall portions of said insulating layer having a greater height than the side wall portions of said ferrule, thereby to permit the cover side walls, when said ferrule is crimped upon said conductors, to extend around the upper surfaces of the ferrule side walls with the free extermities (10) of said cover extending downwardly between said conductors and being held captive solely by the cooperation between the corresponding downwardly extending portions of the ferrule side walls, whereby said protrusions serve to localize the crimping pressure over the piercing means and also press into the conductor insulation to assist in retaining the conductors firmly in the connector.
2. the other of said base and side wall portions containing intermediate its ends a pair of inwardly directed conductor engaging means each consisting of a group of inwardly directed protrusions (5) arranged laterally of and directly opposite said piercing means for engaging the outer surfaces of said conductors, respectively, the protrusions of each group being so arranged that the associated conductor is held captive therebetween, said piercing means being arranged solely on said one of said base and side wall portions and said conductor engaging means being arranged solely on the other of said base and side wall portions;
2. Apparatus as defined in claim 1, wherein said ferrule further includes internal conductor-engaging ribs (8) arranged on opposite sides of said clearance recesses, respectively, each of said ribs extending continuously transversely across said ferrule base portion and completely transversely across said ferrule side wall portions to the free edges (11) thereof.
3. Apparatus as defined in claim 2, wherein each of said insulation piercing means comprises a group of metal spikes that surround an opening contained in the base portion and project upwardly between the ferrule side wall portions.
3. each of said side wall portions containing at its upper edge (11) a clearance recess (7) that defines a pair of upper edge portions arranged at opposite ends of said side wall portion, respectiVely;
4. said side wall portions having such a height as to permit them to be progressively crimped inwardly together upon the upper surfaces of said conductors and downwardly between said conductors, thereby to cause said conductor engaging means to hold the respective conductors captive and to force said conductors into piercing engagement with said insulation piercing means; and b. a trough-shaped cover of insulating material (9) arranged about the external surface of said ferrule, said cover having base and side wall portions contiguous with the corresponding portions of said ferrule, respectively, the side wall portions of said insulating layer having a greater height than the side wall portions of said ferrule, thereby to permit the cover side walls, when said ferrule is crimped upon said conductors, to extend around the upper surfaces of the ferrule side walls with the free extermities (10) of said cover extending downwardly between said conductors and being held captive solely by the cooperation between the corresponding downwardly extending portions of the ferrule side walls, whereby said protrusions serve to localize the crimping pressure over the piercing means and also press into the conductor insulation to assist in retaining the conductors firmly in the connector.
