Abstract
Abstract Printed circuit boards and electrical connectors provide convenient means of assembling circuits in electronic equipment. A packaging system is provided in which printed circuit boards or plug-type electrical connectors may be inserted into a system with zero insertion force. After the printed circuit boards or electrical connectors are supported in a rack, cam-actuated electrical contacts supported on the rack are actuated to make electrical contact with associated contact terminals on the printed circuit board or electrical connector plug. The packaging system includes cam support bars forming journals for cam shafts which actuate the electrical contacts, and contact carrier members releasably support electrical contacts in operative relation to the cam shafts. A rack and pinion mechanism interconnects individual cam shafts to effect simultaneous displacement of the electrical contacts to engage the associated printed circuit boards or electrical plug connectors.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
132 words
As an article of manufacture, a contact carrier member for use in an electrical socket connector assembly, comprising an elongated bar generally U-shaped in cross section to provide a bottom wall joined by upstanding sidewalls spaced apart to provide a passageway therebetween to receive a plug connector, each said sidewall having formed thereon a series of longitudinally spaced transversely extending partitions the free edges of opposed partitions defining said passageway, and a series of passageways extending through the bottom wall and communicating with the spaces defined by said partitions between the sidewalls, each said partition extending beyond the entire free ends of the sidewalls and formed with a concave surface proportioned so that when two contact carrier members are juxtaposed the concave surfaces of opposed partitions have a common center of revolution.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
177 words
In combination, an electrical contact carrier member comprising an elongated bar generally U-shaped in cross section to provide a bottom wall joined by upstanding parallel sidewalls spaced apart, each said sidewall having formed thereon a series of longitudinally spaced transversely extending opposed partitions the free edges of which define a longitudinally extending passageway parallel to the sidewalls, a series of passageways extending through the bottom wall and communicating with the spaces defined between adjacent partitions of each series, and an elongated electrical conductor extending through each said passageway and including a resilient contact portion normally lying in the space between adjacent partitions within the U-shaped member, said combination further comprising a plug connector having a body portion and a blade portion adapted to be inserted into the passageway defined by the opposed partitions in the contact carrier member, and electrical Terminals fixed on the plug connector and disposed on the blade portion thereof in noncontacting juxtaposition to the resilient contact portion when the blade portion of the plug connector is initially inserted into the U-shaped carrier member.
