Abstract
Abstract An electrical connector comprises a housing (51, 72) in which terminals (11, 71) are mounted in upper and lower rows with wire connecting portions (14, 82) of the terminals (11, 71) in longitudinally staggered relation aligned below a tool receiving opening (57) in the housing (51, 72) enabling a tool inserted through the opening (57) to terminate wires in both wire connecting portions (14, 82). The wire connecting portions (14, 82) define wire receiving slots (32) in panels (33) which have struts (39) extending into engagement with the housing (51, 72) during wire insertion to prevent collapse of the panels (33).

Claim 1
Independent Claim
226 words

An electrical connector comprising an insulating housing (51, 72) formed with passageways (29, 29') communicating with opposite mating and wire receiving faces; and, a terminal (11, 71) stamped and formed from sheet metal stock received in the passageway (29, 29') with a contact portion (12, 74) adjacent a mating face and a wire connecting portion (14, 82) adjacent the wire receiving face, the wire connecting portion (14, 82) being of generally channel section and including a panel (33) defining a vertical wire receiving slot (32) bent from a side wall to upstand across the channel with the slot mouth opening at an upper edge of panel (33) to the channel mouth, the housing (51, 72) having a tool admitting opening (57) aligned over the slot (32) through which a terminating tool can be inserted to drive a wire into the slot (32), characterised in that, the housing base wall is formed with a recess (41) below the wire connecting portion (14, 82), the floor of which is spaced from the base (40) of the wire receiving portion, and a lug (39) extends from a lower edge of the panel through the channel base (40) to a location adjacent the floor of the recess (41) to provide a strut (39) supporting the panel (33) during the insertion of a wire into the slot (32) by the tool.
Claim 3
Dependent Claim
23 words
An electrical connector according to claim 1, characterised in that, the said (32) has a blind end located spaced above the channel base.
Claim 4
Dependent Claim
31 words
An electrical connector according to claim 1 or claim 2, characterised in that, the panel (33) comprises an extension of a side wall bent to extend across the base wall (40).
Claim 5
Dependent Claim
62 words
An electrical connector according to claim 3 characterised in that, another panel (34) including another wire receiving slot (31) extends across the channel with the other slot (31) aligned with the one slot (32), the other slot (31) extending to a location between the blind end of one slot (32) and the base (40) and for substantially the height of the channel.
Claim 6
Dependent Claim
39 words
An electrical connector according to claim 4 in which the walls of the other slot (30) are more flexible than the walls of the one slot (31) and the other slot (32) is narrower than the one slot (31).
Claim 7
Dependent Claim
26 words
An electrical connector according to claim 4, characterised in that, the other panel (34) is bent up from a stock portion coextensive with the base (40).
Claim 8
Dependent Claim
46 words
An electrical connector according to claim 4, characterised in that, an arm (30) is struck out from at least one side wall adjacent the one slot (31), which arm is deformable across the channel into clamping engagement with a wire received in a slot (31, 32).
Claim 9
Dependent Claim
