Abstract: The terminal locking block is mounted to the connector housing in two steps, first in a provisional engagement condition and then in a full engagement condition. In the provisional engagement condition, a stopper formed at the rear inside of the terminal locking block stays out of terminal insertion passages, allowing terminal lugs to be inserted into the terminal accommodating chambers, in which the terminal lugs are held by resilient engagement pieces of the connector housing. When the terminal locking block is pushed down and advanced forwardly into the full engagement condition, the stopper is situated immediately behind protrusions of the terminal lugs, thus securely locking them. When it is desired to remove the terminal lugs from the connector housing, the terminal locking block is retracted to the provisional engagement condition and the resilient engagement piece is pried open by a jig to disengage the terminal lug.

Abstract: An integral elastomeric card edge connector provides shorter signal paths through the contact with reduced interference. The card edge contact allows high density interconnection between several layers of multi-layer circuit card without routing signal paths to the card surface. Elastomeric contact tab supports provide positive contact pressure and the necessary wipe action to ensure electrical contact. The process for forming the integral contacts begins with a standard multi-layer card which is then beveled, etched to expose the contact tabs, filled with elastomeric material and processed to expose the tabs supported by elastomeric columns. The connector may be used in card on board technologies or for the connection of multi-chip organic substrates to boards or to other substrates.
