    摘要: A card edge connector for mounting on a circuit board and removeably receiving a circuit card includes an elongated housing defining a card receiving slot. Numerous terminal receiving cavities intersect and extend to both sides of the slot. Alternate cavities include stamped reference (ground or power) terminals and signal terminals, all having downwardly extending board contacts and upwardly extending spring arms. There are numerous similar sets of face to face contacts, each including a reference contact parallel to and substantially overlying an opposed pair of signal contacts. The upwardly extending reference terminal spring arms include oversize pad portions for reducing crosstalk by increasing coupling between the reference and signal terminals. The circuit paths to the circuit board are in an array symmetrical about the centerline of the circuit card, with parallel inner lines of circuits containing only reference contacts and outer lines of circuits containing only signal contacts.

    摘要: A double sided edge connector is provided including a housing formed from a pair of substantially identical hermaphroditic housing halves and aligned pairs of electrical terminals. Each housing half includes a plurality of parallel spaced apart contact guides defining contact receptacles therebetween. Each housing half further includes a longitudinally extending contact retaining wall adjacent the top of the housing half and defining a portion of each contact receptacle. Each terminal includes a central mounting portion, a solder tail at one end and a contact beam at the other end. The contact beam is of a double bent configuration to provide anti-overstress protection to the terminals in use. The terminals are heat staked into the respective receptacles such that the end of the each contact beam is biased against the contact retaining wall. The substantially identical housing halves with the terminals heat staked therein are hermaphroditically mated and are heat staked together.
