Abstract
Connector assemblies are provided for mounting leadless chip carriers to a printed wiring board (PWB). Each connector assembly includes an elongate rigid and electrically insulative body, and electrically conductive leads. The body has two rows of pockets, each containing a lead. Each lead has two widened contact sectors. The shape of the lead is such that with one end mounted in the PWB, the sectors are opposite one another and approximately the same distance from the PWB. Each connector assembly is mounted by soldering the body to the PWB and mounting one end of each lead to the PWB. Each pocket has a channel narrower than the sector and wider than the general lead width, to restrain its associated lead to flexing movement in one direction transverse to the body. The sectors are offset in this transverse direction from the lead end mounted to the PWB, but in different amounts, thus to enable a staggered positioning of adjacent leads. As a chip carrier is inserted, it contacts and elastically deforms the leads, initially driving one sector of each lead against an inside wall of its associated pocket, then deforming that portion of the lead between its two sectors to move them toward each other. With the chip carrier fully inserted, the leads push against the chip carrier pads to electrically link the carrier with PWB circuitry and retain the chip carrier against the PWB.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
