Abstract
Abstract There is disclosed an electrical contact which comprises a substantially rigid electrically conductive body and a substantially flexible contacting portion electrically connected thereto. The contacting portion includes a first segment of insulative material and a second segment of conductive material secured to a selected area on the first segment. The contact is ideally suited for use within a zero force printed circuit board connector, said connector also disclosed.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
251 words
A zero force printed circuit board comprising: a housing of electrically insulated material, said housing having a longitudinally extending central slot adapted to receive a printed circuit board, said housing having a plurality of contact receiving openings on both sides of the central slot, said contact receiving openings being in communication with the central slot, a contact carried within each of the contact receiving openings, each contact comprising a flexible base of electrically insulative material, each base having an outwardly directed portion acting as an electrical contact, an electrically conductive material on the outwardly directed portion of each flexible base, and a substantially rigid electrically conductive pin affixed to each base in electrical communication with the outwardly directed portion of each base, each aforesaid outwardly directed base portion acting as an electrical contact and facing inwardly toward the longitudinal slot whereby when a printed circuit board is positioned in said slot each aforesaid base portion will be adapted to electrically engage the printed circuit board, and actuation means for forcing each outwardly directed base portion into electrical engagement with the printed circuit board when positioned in the slot, said actuation means comprising longitudinal members slideably carried by the housing, each of said members having a portion positioned to engage the electrical contacts on an individual side away from the housing slot, cam means positioned in the housing to force the longitudinal members upon sliding movement thereto toward the housing slot so that the electrical contacts progressively engage the printed circuit board.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
17 words
The invention as set forth in claim 1 and wherein each base is composed of plastic material.
Claim 4
Dependent Claim
20 words
The contact according to claim 2 wherein said plastic material is selected from the group consisting of nylon and Mylar.
Claim 5
Dependent Claim
18 words

Claim 6
Dependent Claim
28 words
The invention as set forth in claim 1 and wherein the electrically conductive material on each base is a metal different from that of the electrically conductive pins.
Claim 7
Dependent Claim
19 words
The invention as set forth in claim 5 and wherein the metal on each base is a noble metal.
