Abstract
Abstract A connector for terminating a coaxial cable is provided which includes a first insulation displacement contact for contacting the shield and a second insulation displacement contact for contacting the central conductor. The contacts are arranged on a support base in an axial sense corresponding to the axis of the cable defined by the central conductor. The process of terminating the coaxial cable comprises stripping the outer insulating jacket and shield from a small end portion of the cable and then inserting that portion into one of the contacts while an unstripped portion is inserted into the other of the contacts. The insulation displacement contacts pierce the insulation to make direct electrical contact to the respective shield or central conductor.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
290 words
A connector for a coaxial cable, said cable comprising: at least one central conductor defining a cable axis; at least one surrounding conductive shield element; a first insulating layer arranged between said shield element and said central conductor; and an outer insulating jacket arranged about said shield element; said connector comprising: first insulation displacement contact means for electrically contacting said shield element by displacement of said insulating jacket; second insulation displacement contact means for electrically contacting said central conductor by displacement of said insulating layer; said first contact means comprising a member including a first slot having a first width and wherein said second contact means comprises a member having a second slot having a second width narrower than said first width and wherein said slots are arranged along said contact axis whereby said cable is adapted to be pressed into said slots; said first and second contact means having blade metal members including pin-positions for connection to a printed circuit board; contact support means comprising a base member for supporting said first and second contact means, said contact means being arranged on said base member along a contact axis with said second contact means following said first contact means and being electrically isolated therefrom, whereby when said cable is connected to said first and second contact means said contact axis corresponds to said cable axis; and a cover member and means for locking said cover member to said base member, the cover member being hinged to said base member to pivot between an open position for inserting said coaxial cable and a closed portion for locking said coaxial cable in place and wherein said cover member includes anvil portions for engaging said cable when said cover member is closed.
Claim 2
Dependent Claim
290 words
A connector for a coaxial cable, said cable comprising: at least one central conductor defining a cable axis; at least one surrounding conductive shield element; a first insulating layer arranged between said shield element and said central conductor; and an outer insulating jacket arranged about said shield element; said connector comprising: first insulation displacement contact means for electrically contacting said shield element by displacement of said insulating jacket; second insulation displacement contact means for electrically contacting said central conductor by displacement of said insulating layer; said first contact means comprising a member including a first slot having a first width and wherein said second contact means comprises a member having a second slot having a second width narrower than said first width and wherein said slots are arranged along said contact axis whereby said cable is adapted to be pressed into said slots; said first and second contact means having blade metal members including pin-positions for connection to a printed circuit board; contact support means comprising a base member for supporting said first and second contact means, said contact means being arranged on said base member along a contact axis with said second contact means following said first contact means and being electrically isolated therefrom, whereby when said cable is connected to said first and second contact means said contact axis corresponds to said cable axis; and a cover member and means for locking said cover member to said base member, the cover member being hinged to said base member to pivot between an open position for inserting said coaxial cable and a closed portion for locking said coaxial cable in place and wherein said cover member includes anvil portions for engaging said cable when said cover member is closed.
Claim 3
Dependent Claim
34 words
A connector as in claim 1 wherein said first contact means and said second contact means comprise a contact set for a coaxial cable and wherein said connector includes a plurality of said contacts.
Claim 4
Dependent Claim
28 words
A connector as in claim 2 wherein said base member includes a slot for receiving said coaxial cable and wherein said contact set is arranged within said slot.
Claim 5
Dependent Claim
163 words
A process for terminating a coaxial cable, using the electrical connector as defined in claim 1, said cable comprising: at least one central conductor defining a cable axis; at least one surrounding conductive shield element; a first insulating layer arranged between said shield element and said conductor; and an outer insulating jacket arranged about said shield element; said process comprising: providing said electrical connector stripping away a short portion of said outer insulating jacket and said shield element from an end portion of said coaxial cable; inserting said end portion of said coaxial cable into said second insulation displacement contact means so that said said insulating layer is displaced and said second insulation displacement contact means is in intimate electrical contact with said central conductor; and inserting an unstripped portion of said cable into said first insulation displacement contact means so that said insulating jacket is displaced by said first insulation displacement contact means to make intimate electrical contact with said shield element.
Claim 6
Dependent Claim
25 words
A process as in claim 4 further including the step of locking said coaxial cable into contact with first and second insulation displacement contact means.
Claim 7
Dependent Claim
20 words
A process as in claim 5 further including the step of connecting said electrical connector to a printed circuit board.
