Abstract
Abstract A flat cable having laterally spaced ribbon conductors embedded in its insulation is inserted into a plastic block containing a rotatable cylinder. The cylinder has a diametrically oriented slot for the reception of the inserted end of the flat cable. An annular space circumscribes the cylinder and a number of serrated contacts extend into the annular space so that when the cylinder is rotated the teeth on the contacts peel the insulation from the cable to establish electrical engagement with the ribbon conductors.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
119 words
A connector for engaging a flat cable having at least one ribbon conductor therein covered With insulation material, the connector comprising a block having an entrance slot for the insertion of one end of the flat cable, a cylindrical member rotatable within said block having a diametrically disposed slot therein registrable with said entrance slot, said cylindrical member having a cross section such that an annular space is formed between said cylindrical member and the interior of said block, and a contact element for each ribbon conductor extending into said annular space at a location spaced angularly from said entrance slot, each contact element having means thereon for removing some of said insulation material and engaging electrically said conductor.
Claim 2
Dependent Claim
119 words
A connector for engaging a flat cable having at least one ribbon conductor therein covered With insulation material, the connector comprising a block having an entrance slot for the insertion of one end of the flat cable, a cylindrical member rotatable within said block having a diametrically disposed slot therein registrable with said entrance slot, said cylindrical member having a cross section such that an annular space is formed between said cylindrical member and the interior of said block, and a contact element for each ribbon conductor extending into said annular space at a location spaced angularly from said entrance slot, each contact element having means thereon for removing some of said insulation material and engaging electrically said conductor.
Claim 3
Dependent Claim
16 words
A connector in accordance with claim 1 in which said insulation-removing means includes laterally spaced serrations.
Claim 4
Dependent Claim
55 words
A connector in accordance with claim 2 in which each contact element includes a strip portion extending generally tangentially into said annular space at said angularly spaced location, said serrations projecting radially inwardly from one side of said contact element toward said cylindrical member and the other side of each contact element abutting said block.
Claim 5
Dependent Claim
31 words
A connector in accordance with claim 3 in which said angularly spaced location is such that the serrated end of each contact is quadrantly located with respect to said entrance slot.
Claim 6
Dependent Claim
33 words
A connector in accordance with claim 4 in which said block includes a resilient seal projecting radially inwardly into said annular space, said seal being between said entrance slot and said contact element.
Claim 7
Dependent Claim
27 words
A connector in accordance with claim 5 including a second seal disposed on said cylindrical member and rotatable therewith into a position substantially opposite said first seal.
Claim 8
Dependent Claim
41 words
A connector in accordance with claim 6 including an additional seal on said block extending radially inwardly to said cylindrical member, said additional seal being located in an opposite angular direction from said first seal with respect to said entrance slot.
