Latching slotted beam terminal

Claim 2

A stamped and formed electrical terminal for forming an electrical connection with an insulated conductor and having a conductor engaging portion and a mating portion extending from opposite ends of a main body, said conductor engaging portion having a pair of closely spaced parallel substantially planar plate sections connected by a bight extending along corresponding first sides of the plate sections, each plate section having a pair of spaced apart arms extending from second corresponding sides of said plate sections, said main body being connected to a third side of at least one of said plate sections characterized by the arms of one said plate section being of a first set of dimensions of width and length to define therebetween a slot narrower than the conductor with the arms being stiff and unyielding to deflection in the plane of said one plate section and the arms of the second plate section being of width and length dimensions to be of greater length than said arms of said one plate section and defining therebetween a slot wider than the conductor to be resilient and more capable of deflection in the plane of said second plate than the arms of said one plate section, and said second arms having outwardly directed latching shoulders adjacent the free ends thereof.

Claim 3

An electrical connecting device for forming electrical connections with conductors of multi-conductor flat cable of the type having a plurality of conductors in parallel side-by-side relationship and contained in a web of insulating material, said connecting device having a base member of insulating material with a plurality of terminal passages extending therethrough from a mating face to a cable receiving face, a cover member adopted to be assembled with a base member against the cable receiving face side thereof, the cover member having a plurality of openings therein each aligned with a respective terminal opening of the base member, and a plurality of electrical terminals each mounted in a respective passage of said base member with a mating portion directed toward said mating face and an insulation piercing conductor engaging portion extending from the cable receiving face, characterized by: said insulation piercing conductor engaging portion being formed by a pair of plates connected by a bight so as to overlie one another, the first of said plates having a first pair of spaced arms of such length and width dimensions as to define a narrow conductor engaging slot therebetween and to be relatively stiff and inflexible in the plane of said first plate, and said second plate having a second pair of arms of length and width dimensions as to be of greater length than said first arms and to define a second slot therebetween of greater width than said first slot, said second arms of said second plate being more flexible in the plane of said second plate than the first arms and having outwardly directed shoulders on the ends thereof so as to engage in respective apertures in said cover member to engage therewith.

Claim 4

An electrical connecting device for forming electrical connections with conductors of multi-conductor flat cable of the type having a plurality of conductors in parallel side-by-side relationship and contained in a web of insulating material, said connecting device having a base member of insulating material with a plurality of terminal passages extending therethrough from a mating face to a cable receiving face, a cover member adopted to be assembled with a base member against the cable receiving face side thereof, the cover member having a plurality of openings therein each aligned with a respective terminal opening of the base member, and a plurality of electrical terminals each mounted in a respective passage of said base member with a mating portion directed toward said mating face and an insulation piercing conductor engaging portion extending from the cable receiving face, characterized by: said insulation piercing conductor engaging portion being formed by a pair of plates connected by a bight so as to overlie one another, the first of said plates having a first pair of spaced arms of such length and width dimensions as to define a narrow conductor engaging slot therebetween and to be relatively stiff and inflexible in the plane of said first plate, and said second plate having a second pair of arms of length and width dimensions as to be of greater length than said first arms and to define a second slot therebetween of greater width than said first slot, said second arms of said second plate being more flexible in the plane of said second plate than the first arms and having outwardly directed shoulders on the ends thereof so as to engage in respective apertures in said cover member to engage therewith.

Claim 5

An electrical connecting device according to claim 2 wherein said narrow conductor engaging slot is no greater in width than said conductor.

Claim 6

An electrical connecting device according to claim 2 wherein said slot of said second plate is no narrower in width than said conductor.

Claim 7

An electrical connecting device according to claim 2 wherein said slot of said first plate is no greater in width than said conductor and said slot in said second plate is no narrower in width than said conductor.

Claim 8

An electrical connecting device according to claim 2 wherein said openings in said cover member each have lugs defining shoulders engaged by the shoulders of said second arms.
