Abstract
Abstract A high density electrical connector comprising a connector body containing insulation displacement contact elements and a cover assembly having a first cover portion and a second cover portion between which electrical wires are retained. The first cover portion has contact insertion holes for receiving the ends of the contact elements. The second cover portion has a longitudinal slit extending from one end throughout a majority of its length for receiving the wires to be connected, has recesses on both sides of the slit for receiving the ends of the contact elements and has wire receiving grooves passing from the slit across the recesses to the edge of the second cover portion.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
151 words
A high density electrical connector comprising a connector body containing a multiplicity of insulation displacement contact elements and a cover assembly for retaining insulated electrical conductors, said cover assembly including a first cover portion and a second cover portion, said first cover portion having contact insertion holes for receiving the conductor connecting ends of said insulation displacement contact elements and said second cover having a longitudinal slit extending from one end throughout a majority of the length of said second cover portion, a multiplicity of contact element receiving recesses on both sides of said longitudinal slit for receiving the ends of said contact elements extending through said contact insertion holes through said first cover portion and a multiplicity of transverse insulated electrical conductor receiving grooves, each extending from said longitudinal slit to the adjacent edge of said second cover, with one groove passing across each of said contact element receiving recesses.
Claim 2
Dependent Claim
151 words
A high density electrical connector comprising a connector body containing a multiplicity of insulation displacement contact elements and a cover assembly for retaining insulated electrical conductors, said cover assembly including a first cover portion and a second cover portion, said first cover portion having contact insertion holes for receiving the conductor connecting ends of said insulation displacement contact elements and said second cover having a longitudinal slit extending from one end throughout a majority of the length of said second cover portion, a multiplicity of contact element receiving recesses on both sides of said longitudinal slit for receiving the ends of said contact elements extending through said contact insertion holes through said first cover portion and a multiplicity of transverse insulated electrical conductor receiving grooves, each extending from said longitudinal slit to the adjacent edge of said second cover, with one groove passing across each of said contact element receiving recesses.
Claim 3
Dependent Claim
57 words
The connector of claim 1 wherein said second cover portion has steps formed at both longitudinal ends of a height to define a spacing between the major portions of said first and second cover portions to firmly retain insulated electrical conductors between said cover portions in said insulated electrical conductor receiving grooves in said second cover portion.
Claim 4
Dependent Claim
69 words
The connector of claim 2 wherein said cover assembly has projections at its ends that mate with slots in resilient legs at the ends of said connector body to hold said body and said cover assembly together with the ends of the contact elements extending through said contact insertion holes in said first cover portion and being connected to insulated electrical conductors between said cover portions in said grooves.
Claim 5
Dependent Claim
68 words
The connector of claim 1 wherein said first cover portion has a central longitudinal rib and said connector body has a corresponding central recess to receive said rib when said body and cover assembly are assembled with the ends of the contact elements extending through said contact insertion holes in said first cover portion and being connected to insulated electrical conductors between said cover portions in said grooves.
Claim 6
Dependent Claim
51 words
The connector of claim 4 wherein said cover assembly has projections at its ends that mate with slots in resilient legs at the ends of said connector body to hold said body and said cover assembly together when they are assembled to connect said contact elements to the insulated electrical wires.
