Abstract: An electronic connector is configured to removably receive either a circuit card of a first type, having one row of contacts per side, on an insertion tab adjacent to an insertion edge, or a circuit card of a second type, having two rows of contacts per side. Two rows of spring contacts are provided for this purpose on each side of a central card-receiving slot. Interposing means are also provided to prevent contact between a daughter card of the first type fully inserted in this slot and one of these rows on each side. These interposing means may consist of a slotted interposer structure slid over a portion of the insertion tab of the card, or alternately of a pair of pivotable interposers mounted along the length of the connector, to be pivoted by sections of daughter cards of the first type so that vanes extending from these interposers will push these springs away from the card.

Abstract: A combined electrical connector and connector nesting assembly has a frame with a first section adapted to receive an edge of a printed circuit board and a second section adapted to receive a connector of a cable assembly. The first section has a card edge receiving slot and spring contacts can be inserted thereinto. The second section is located parallel to, but offset from the first section such that when a printed circuit board is inserted into the assembly, a connector located in the second section can receive contact pins projecting from the printed circuit board. The assembly frame can be snap-locked into an electronic component chassis and the connector can be snap-locked into the second section of the frame.

Abstract: An electrical contact has a main body section, a top contact section, and a bottom contact section. The main body section has a general ring shape with a general diagonally shaped open area extending from a top of the main body section to a bottom of the main body section. The top contact section extends from the top of the main body section and the bottom contact section extends from the bottom of the main body section.

Abstract: A card edge connector having spring contacts that are partially movable by insertion of a circuit board into the connector. The contacts include two contacts that electrically contact each other when a circuit board is not connected to the connector. The two contacts are moved by insertion of a circuit board into the connector which results in disconnection of the electrical contact between the two contacts. This allows a signal contact to be contacted and grounded by a ground contact while the connector is not in use and, nonetheless allows independent ground and signal functions of the two contacts when a circuit board is connected to the connector.

Abstract: A card edge connector that has a base, spring contacts connected to the base, and a cover movably mounted on the base. The cover is adapted to move at least some of the spring contacts from a retracted position to a contact position upon insertion of a first type of card into the connector and, adapted not to move spring contacts upon insertion of a second type of card into the connector. The cover is adapted to be moved by the first type of card, but not by the second type of card. Lateral support is provided to the cover by the base to prevent the cover from being substantially pushed laterally outward by the spring contacts. Clips on the cover are provided to prevent the first type of card from being removed from the connector without moving the cover.

Abstract: An electrical connector for providing a snap-lock connection and automatic disconnection from a second connector. The electrical connector has a housing, a plurality of contacts, a snap-lock latch and a movable outer hood. The snap-lock latch can automatically mechanically connect and retain the housing to a second connector. The movable outer hood can be pulled by a user after connection which disconnects the latch and results in the disconnection of the electrical connector from the second connector.

Abstract: A card edge connector of the type used to connect a daughter printed circuit board with a mother printed circuit board. The connector has a housing, a plurality of signal contacts, and an electromagnetic grounding shield to prevent electromagnetic impulses from generating or degrading signals in the signal contacts.

Abstract: An electrical connector for establishing electrical connection between spaced printed circuit boards, for example, comprising a spiral-wound elongated spring member formed of a one-piece blank and being longitudinally resilient for establishing firm surface contact between circuit boards and radially resilient to provide firm contact in a surrounding receptacle when either end of the connector is compressed. A signal connector is fitted into a carrier block and surrounded by ground connectors to protect the signal from interference. The connector design is small in overall length to minimize connector-length related disturbances to the signal.

Abstract: A low insertion force electrical connector system comprises a receptacle having a plurality of electrical contacts arranged in at least two opposing rows. A low insertion force system selectively spaces apart or closes the electrical contacts to limit insertion of a circuit board with a low force. Devices are provided for aligning and locking the circuit board within the receptacle and an actuating system is arranged to serially operate the aligning and locking devices first followed by the low insertion force system.

Abstract: A dual-in-line connector assembly of the closed-entry, closed-bottom type having an integral structure comprised of a base and a body of closely conforming configuration. The integral assembly defines a number of socket areas arranged in two parallel rows which communicate with a flux rinsing drainage system comprising a plurality of drainage paths of two different configurations which lead to orifices in the assembly exterior located away from the contacts. Drainage paths of the first type include a drainage chute in the socket area floor which lead directly to the exterior via an opening in the bottom of the drainage chute. The second type of drainage path includes a similar drainage chute leading to a large drainage opening that communicates with an extended oval-shaped centered recess which contributes a dual function of effecting a snap-on locking assembly arrangement.

Abstract: An electrical connector system comprises a connector receptacle including a body shell member and a plurality of independent segments with each segment supporting opposing rows of contacts. The segments are supported in the body shell in an independently floating arrangement. Each segment includes a system permitting individual independent alignment of the segment to a circuit board. Preferably, the receptacle includes a low insertion force mechanism which permits a circuit board or electronic module to be inserted or retrieved with very little effort by the operator.
