Abstract
Abstract A connector of zero insertion force type includes a cam (20,22) movable responsively to operator input to open contact elements (16,18) for insertion therein of terminal pins of an electronic package, the contact elements (16,18) being so configured and supported as to impart reverse movement to the cam (20,22) upon discontinuance of the operator input. and to resiliently engage the terminal pins.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
142 words
An electrical connector for interconnecting a plurality of terminal pins in predetermined array to companion apparatus, comprising: (a) a base; (b) a plurality of contacts supported by said. base in said array, each such contact having a first terminal for connection to said companion apparatus and a second terminal adapted for receiving one such terminal pin and having facing elements biased into preselected attitude for electrically engaging said terminal pin; and (c) first and second cam means supported in said connector for movement responsively to operator input in respective opposite first and second senses for engaging said facing elements of said contacts and displacing same from such biased attitude to facilitate low force insertion of said terminal pins therein, said first and second cam means defining respective first and second surfaces accessible exteriorly of said base for receipt of said operator input.
Claim 2
Dependent Claim
142 words
An electrical connector for interconnecting a plurality of terminal pins in predetermined array to companion apparatus, comprising: (a) a base; (b) a plurality of contacts supported by said. base in said array, each such contact having a first terminal for connection to said companion apparatus and a second terminal adapted for receiving one such terminal pin and having facing elements biased into preselected attitude for electrically engaging said terminal pin; and (c) first and second cam means supported in said connector for movement responsively to operator input in respective opposite first and second senses for engaging said facing elements of said contacts and displacing same from such biased attitude to facilitate low force insertion of said terminal pins therein, said first and second cam means defining respective first and second surfaces accessible exteriorly of said base for receipt of said operator input.
Claim 3
Dependent Claim
41 words
The connector claimed in claim 1 wherein said first cam means is supported by said base for translatory movement in said connector and wherein said second cam means is supported by said first cam means for translatory movement in said connector.
Claim 4
Dependent Claim
32 words
The connector claimed in claim 1 or claim 2 further including a cover having openings therethrough in registry with said contacts for passage of said terminal pins into residence in said connector.
Claim 5
Dependent Claim
53 words
The connector claimed in any preceding claim wherein such first and second cam means comprise respective first and second plate members defining openings therethrough for passage of said contacts, plate member surface bounding said openings being engageable with said contacts in the course of said movements of said first and second cam means.
Claim 6
Dependent Claim
60 words
The connector claimed in claim 4 wherein said first and second plate members include respective first and second plate sections each having a tab extending endwise orthogonally thereof, such tabs extending directionally oppositely of one another in said connector and defining respective abutments for the plate sections in the course of said movements of said first and second cam means.
Claim 7
Dependent Claim
20 words
The connector claimed in claim 5 wherein exterior surfaces of said tabs constitute said cam means first and second surfaces.
Claim 8
Dependent Claim
134 words
An electrical connector for interconnecting a plurality of terminal pins in predetermined array to companion apparatus, comprising: (a) a base; (b) a plurality of contacts supported by said base in said array, each such contact having a first terminal for connection to said companion apparatus and a second terminal adapted for receiving one such terminal pin and having facing elements biased into preselected attitude for electrically engaging said terminal pin; and (c) cam means supported in said connector for movement responsively to an actuation force in first sense for engaging said facing elements of said contacts and displacing same from such biased attitude to facilitate low force insertion of said terminal pins therein, said cam means being displaced in second sense opposite said first sense by said contacts upon discontinuance of said actuation force.
Claim 9
Dependent Claim
134 words
An electrical connector for interconnecting a plurality of terminal pins in predetermined array to companion apparatus, comprising: (a) a base; (b) a plurality of contacts supported by said base in said array, each such contact having a first terminal for connection to said companion apparatus and a second terminal adapted for receiving one such terminal pin and having facing elements biased into preselected attitude for electrically engaging said terminal pin; and (c) cam means supported in said connector for movement responsively to an actuation force in first sense for engaging said facing elements of said contacts and displacing same from such biased attitude to facilitate low force insertion of said terminal pins therein, said cam means being displaced in second sense opposite said first sense by said contacts upon discontinuance of said actuation force.
Claim 10
Dependent Claim
45 words
The connector claimed in claim 7 wherein said cam means comprises a plate member defining openings therethrough for passage of said contacts, plate member surface bounding said openings being engageable with said contacts in the course of said first sense movement of said cam means.
Claim 11
Dependent Claim
121 words
An electrical connector for interconnecting a plurality of terminal pins in predetermined array to companion apparatus, comprising: (a) a base; (b) a plurality of contacts supported by said base in said array, each such contact having a first terminal for connection to said companion apparatus and a second terminal adapted for receiving one such terminal pin, each said contact including first and second individual contact elements of identical configuration so disposed in said base as to have respective facing surfaces in resilient mutual engagement; and (c) cam means supported in said connector for movement responsively to operator input for engaging said contact elements and displacing same from such resilient mutual engagement to facilitate low force insertion of said terminal pins therein.
Claim 12
Dependent Claim
121 words
An electrical connector for interconnecting a plurality of terminal pins in predetermined array to companion apparatus, comprising: (a) a base; (b) a plurality of contacts supported by said base in said array, each such contact having a first terminal for connection to said companion apparatus and a second terminal adapted for receiving one such terminal pin, each said contact including first and second individual contact elements of identical configuration so disposed in said base as to have respective facing surfaces in resilient mutual engagement; and (c) cam means supported in said connector for movement responsively to operator input for engaging said contact elements and displacing same from such resilient mutual engagement to facilitate low force insertion of said terminal pins therein.
Claim 13
Dependent Claim
58 words
The connector claimed in claim 9 wherein said cam means comprises first and second cam members supported in said connector for movement in respective opposite first and second senses, said first cam member selectively engaging such first contact elements and said second cam member selectively engaging such second contact elements i in the course of such movement thereof.
