Abstract
Abstract An electrical connector assembly for providing zero force against a printed circuit board during positioning or removal of the board within the connector. The assembly includes a resilient electrically insulative means for engaging each of the contacting portions of the contacts positioned within the connector's housing. An actuating means is employed to engage said electrically insulative means prior to insertion and removal of the circuit board to provide a progressive removal of the contacting portions of the contacts from within the housing's slot.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
198 words
A connector assembly comprising: a housing including a slot therein for receiving a printed circuit board having a plurality of electrically conductive areas thereon; a plurality of contacts positioned within said housing in aligned relationship, each of said contacts including a contacting portion at least partially positioned within said slot for engaging one of said electrically conductive areas on said printed circuit board when said board is positioned within said slot, a substantially centrally located retaining portion positively retained within said housing, and a tail portion extending from said housing, each of said contacting portions of said contacts including an end portion thereon, said end portion not engaging said circuit board; resilient electrically insulative means positioned within said housing, said insulative means including a base portion positively seated within said housing, an intermediate portion, and an angular head portion substantially surrounding each of said end portions of said contacting portions of said contacts; and actuating means comprising a substantially elongated bar for engaging said angular head portion of said resilient electrically insulative means to progressively remove said contacting portions of said contacts from within said slot prior to insertion and removal of said circuit board within said slot.
Claim 2
Dependent Claim
198 words
A connector assembly comprising: a housing including a slot therein for receiving a printed circuit board having a plurality of electrically conductive areas thereon; a plurality of contacts positioned within said housing in aligned relationship, each of said contacts including a contacting portion at least partially positioned within said slot for engaging one of said electrically conductive areas on said printed circuit board when said board is positioned within said slot, a substantially centrally located retaining portion positively retained within said housing, and a tail portion extending from said housing, each of said contacting portions of said contacts including an end portion thereon, said end portion not engaging said circuit board; resilient electrically insulative means positioned within said housing, said insulative means including a base portion positively seated within said housing, an intermediate portion, and an angular head portion substantially surrounding each of said end portions of said contacting portions of said contacts; and actuating means comprising a substantially elongated bar for engaging said angular head portion of said resilient electrically insulative means to progressively remove said contacting portions of said contacts from within said slot prior to insertion and removal of said circuit board within said slot.
Claim 3
Dependent Claim
18 words
The connector assembly according to claim 1 wherein said resilient electrically insulative means comprises a substantially solid member.
Claim 4
Dependent Claim
37 words
The connector assembly according to claim 1 wherein said elongated bar member includes a pointed end portion for engaging said resilient electrically insulative means to provide said progressive removal of said contacting portions from within said slot.
Claim 5
Dependent Claim
21 words
The connector assembly according to claim 1 wherein said housing includes an opening therein for receiving said substantially elongated bar member.
Claim 6
Dependent Claim
17 words
The connector assembly according to claim 1 wherein said elongated bar member is substantially angular in cross-section.
Claim 7
Dependent Claim
42 words
The connector assembly according to claim 1 wherein said housing further includes retention means for positively engaging said angular head portion of said resilient electrically insulative means to define the positioning relationship of said contacting portions of said contacts within said slot.
Claim 8
Dependent Claim
34 words
The connector assembly according to claim 6 wherein said actuating means further engages said retention means of said housing during said progressive removal of said contacting portions of said contacts from within said slot.
Claim 9
Dependent Claim
79 words
The connector assembly according to claim 1 wherein said elongated bar member includes first and second extending portions, said first extending portion including a pointed end portion for engaging said resilient electrically insulative means to provide said progressive removal of said contacting portions from within said slot, said second extending portion positioned relative to said first extending portion for engaging said housing to provide alignment of said first extending portion during said engagement with said resilient electrically insulative means.
Claim 10
Dependent Claim
25 words
The connector assembly according to claim 8 wherein said housing includes an opening therein for receiving said first extending portion of said elongated bar member.
Claim 11
Dependent Claim
21 words
The connector assembly according to claim 8 wherein said second extending portion is positioned substantially parallel to said first extending portion.
