Abstract
Abstract An insulation displacing contact and connector are disclosed for effecting electrical engagement with closely spaced conductors of a multi-conductor flat flexible cable. The elements of the contact include a plurality of parallel tines spaced along a plane defined by the axis of the conductor and defining therebetween at least two insulation displacing slots which form a tortuous path for the conductor. Latching means may be provided on the free end of at least one tine to engage and secure a cover to a contact carrying connector base.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
90 words
A contact terminal for effecting insulation displacing engagement with a conductor of a multi-conductor cable in which the conductors are on close centerlines, said terminal comprising: a flat metal plate body having at least three parallel closely spaced tines extending from one edge, each said tine having a concave transverse profile with the concavity of adjacent tines being oppositely directed, said tines lying substantially in a common plane and defining an insulation displacing slot between adjacent pairs of tines; and a matable portion extending from another edge of said body.
Claim 2
Dependent Claim
90 words
A contact terminal for effecting insulation displacing engagement with a conductor of a multi-conductor cable in which the conductors are on close centerlines, said terminal comprising: a flat metal plate body having at least three parallel closely spaced tines extending from one edge, each said tine having a concave transverse profile with the concavity of adjacent tines being oppositely directed, said tines lying substantially in a common plane and defining an insulation displacing slot between adjacent pairs of tines; and a matable portion extending from another edge of said body.
Claim 3
Dependent Claim
17 words
A contact terminal according to claim 1 further comprising: a locking lance extending from said contact body.
Claim 4
Dependent Claim
20 words
A contact terminal according to claim 1 wherein: the free ends of said tines are profiled to effect insulation piercing.
Claim 5
Dependent Claim
22 words
A contact terminal according to claim 1 wherein: the free end of at least one tine is profiled to form a latch.
Claim 6
Dependent Claim
133 words
An electrical connector assembly for terminating multi-conductor cable having close center axis spacing between the conductors of said cable, said connector assembly comprising: a base having a plurality of contact receiving slots therein; a plurality of contact terminals each mounted in a respective one of said cavities, each said contact terminal having a flat metal plate body with at least three parallel closely spaced tines extending from a first edge and at least one mating engageable portions extending from another edge, said tines defining therebetween at least two conductor receiving slots, each said tine having a concave configuration with the concavity of adjacent tines being oppositely directed; and a cover having a plurality of contact receiving recesses therein, said recesses having a configuration adopted to guide and restrain the movement of said tines.
Claim 7
Dependent Claim
133 words
An electrical connector assembly for terminating multi-conductor cable having close center axis spacing between the conductors of said cable, said connector assembly comprising: a base having a plurality of contact receiving slots therein; a plurality of contact terminals each mounted in a respective one of said cavities, each said contact terminal having a flat metal plate body with at least three parallel closely spaced tines extending from a first edge and at least one mating engageable portions extending from another edge, said tines defining therebetween at least two conductor receiving slots, each said tine having a concave configuration with the concavity of adjacent tines being oppositely directed; and a cover having a plurality of contact receiving recesses therein, said recesses having a configuration adopted to guide and restrain the movement of said tines.
Claim 8
Dependent Claim
17 words
The connector assembly according to claim 5 further comprising latching means securing said cover on said base.
Claim 9
Dependent Claim
45 words
A connector assembly according to claim 5 further comprising: latching means on the free end of at least one of said tines of said contact terminals, said latching means interengaging with said cover member to clampingly secure the cable between said cover and said base.
Claim 10
Dependent Claim
62 words
A connector assembly according to claim 5 further comprising: interengageable means on said tines and said cover member and comprising laterally outwardly directed free end portions on said tines, said free end portions having shoulders directed towards said base, said recesses in said cover including ledges with which said shoulders engage to clampingly secure the cable between the cover and the base.
