Abstract
Abstract A connector for making interconnection between the conductors in a flat cable and a terminal post grid on a printed circuit board has a molded plastic contact carrier in which the wire connection ends of the contacts exit from one surface of the carrier and the wiping blades exit from the opposite surface. The wiping blades are progressively further spaced from the center of the carrier than their associated wire connection ends progressing from the center toward both ends of the carrier to leave space at the ends of the carrier on the wire contact surface for cover latching members for latching a cover over a flat cable with its conductors electrically connected to the wire connection ends of the contact elements.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
255 words
A flat cable connector comprising: a molded plastic contact carrier, a multiplicity of electrical contact elements molded into said contact carrier in two parallel rows, each said contact element having a slotted insulation displacement wire connection end protruding from one surface of said carrier and a wiping blade protruding from the opposite surface of said carrier, the wire connection ends of said contacts being staggered to receive the parallel conductors of a flat cable alternately in a contact in one row and then a contact in the other row and the wiping blade of a contact in one row being aligned with the wiping blade of a contact in the other row, said wiping blades being progressively further spaced from the center of said carrier than their associated wire connection ends progressing from the center toward both ends of said carrier, a pair of latching members extending from said one surface of said carrier, one at each end of the rows of said protruding wire connection ends of said contact elements, said latching members being at least partially in transverse planes through said carrier that also pass through the end wiping blades extending from the opposite surface of said carrier and extending longitudinally of said carrier toward the ends thereof no further than the end wiping blades, a plastic cover slotted on one surface to receive said wire connection ends of said contact elements and being formed at its ends with portions complementary to said latching members for latching said cover to said contact carrier.
Claim 2
Dependent Claim
255 words

Claim 3
Dependent Claim
67 words
The flat cable connector of claim 1 wherein said latching members on said contact carrier comprise spring metal latching blades molded into each end of said contact carrier, each said latching blade being formed with a cover latching aperture and wherein said cover is formed with latching projections to fit into said cover latching apertures in said latching blades to latch said cover to said contact carrier.
Claim 4
Dependent Claim
89 words
The flat cable connector of claim 2 wherein each of said latching blades extends through an opening in said cover when latched and is formed with a strain relief latching aperture spaced further from said one surface of said contact carrier than said cover latching aperture, and including a plastic strain relief clip to fit over said cover and being formed at its ends with latching projections to fit into said strain relief latching apertures in said latching blades to latch said strain relief clip to said contact carrier.
Claim 5
Dependent Claim
26 words
The flat cable connector of claim 2 or 3 wherein there are two of said spring metal latching blades at each end of said contact carrier.
Claim 6
Dependent Claim
71 words
The flat cable connector of claim 1, 2 or 3 including a plastic body receiving and retaining said contact carrier; said body having a generally U-shaped cross-section and a length corresponding to the length of said contact carrier, the base thereof having apertures therethrough into which said wiping blades of said contacts extend into position for making wiping contact with terminal posts entering said apertures from the exterior of said body.
