This socket permits zero force or low force insertion of circuit panels into the socket and is of the type in which the circuit panel is rotated from a first position to a second position where deflection is imparted to the two contact springs. The contact terminals used with this socket are insertable into an insulative housing through the rear of the housing. A cantilever spring extending from the rear of the contact terminal is located on one side of a panel receiving slot and a curved spring is located on the other side of the panel receiving slot.

The socket comprises an insulative housing base and a reciprocal cap frame located on top of the insulative housing. A plurality of resilient contact terminals are positioned along the sides of the insulative housing around the periphery of a cavity for receiving the PQFP package. Each contact terminal is inwardly deflectable upon movement of the cap so that gullwing leads of the PQFP package will be received between the contact terminal and an inwardly facing ledge. The socket is suitable for use with automatic loading equipment.

Abstract: An integrated circuit package socket includes an insulating housing having a plurality of side by side terminals profiled for receipt of a square package with leads extending therefrom. The socket also includes a camming member disposed above the housing which has a camming surface which contacts a portion of each of the terminals to move the terminals into and out of electrical engagement with the leads of the package. The camming member multiplies the force applied directly to the camming member to cause the desired rotation. Relaxation of the camming member causes a reverse rotation of the contacts into electrical engagement with the package leads.

Abstract: Four embodiments of a burn-in socket for gull wing configured semiconductor packages are disclosed where each of the embodiments includes latching means which a mechanical advantage assisting in the installation of the carrier and package. Two of the embodiments include four centered posts which include helical ramparts which contact directly on the upper surface of the carrier. A third embodiment is disclosed which includes a lid which rotates over the upper face of the carrier, where the cover includes a post having a helical rampart where the helical rampart contacts a shoulder of the socket which lowers the cover. The fourth embodiment discloses two overlapping doors where the outer door contacts the inner door thereby closing the inner door moving the carrier downward.

Abstract: A burn-in socket for a zig-zag inline package includes an insulative housing carrying a plurality of electrical terminals which include convexly formed sections defining contact portions. The apices of the convexly formed sections are laterally offset to increase the amount of deflection obtainable from any given thickness of package lead. The convexly formed sections are axially offset to stagger the insertion force and the terminals are designed to plastically deform under certain conditions to limit the normal force between the contacts and the package leads.

Abstract: A connector housing included multiple rows of contacts with the housing molded to provide an orientation to receive printed circuit board modules inserted therein at an angle of substantially less than 90 degrees relative to a common printed circuit board module mounting board. The rows of the housings have at each end board guide and support slots containing latches integrally therewith and a central structural web connecting said rows and guide ends, the such web providing structural support of said rows and at the same time, serving as a path of flow during the connector molding process.

Abstract: A connector for interconnecting a zig-zag inline package to a printed circuit board has a plurality of contacts in two parallel and offset rows. The contacts and housing are dimensionally controlled to be preloaded only when installed in the housing cavity, providing predictable preload and resultant insertion force.

Abstract: Sockets specifically adapted for burn-in testing of small outline integrated circuit components are disclosed. The multicontact sockets have terminals located in cavities oriented to receive the small outline integrated circuit leads. The terminals are located between adjacent leads and are positioned to resiliently engage the interstitial edges of the package leads, thus imparting minimal stress normal to the plane of the leads. Both surface mount and through-hole sockets are disclosed and the terminals as depicted can have a bowed leaf spring configuration or a preloaded flat terminal, arcuately deformed for retention within the housing cavities. Thus the small outline integrated circuit components can be routinely inserted into the sockets for test purposes. The sockets can also be used in a conventional manner to socket integrated circuit components such as SOICs on a printed circuit board.

Abstract: The invention disclosed herein relates to a biasing means provided in one end of a card-receiving slot of a card edge connector. The biasing means includes a spring loaded wedge slidably positioned in a sloping passage at one end of the slot. The wedge includes a vertical surface which engages a side of the card as the card is inserted in the slot. The wedge moving down the sloping passage increases the slot length to accommodate the card width without exerting significant longitudinal force against the end walls of the connector. Further, the wedge cannot be moved up the passage by an uneven force being exerted on the card; accordingly, the card can only be removed from the slot in a straight line.

Abstract: The present invention relates to an applicator tool capable of picking up loose miniature spring sockets and inserting them into holes in a printed circuit board. More particularly, the tool has dual air lines, one being connected to a compressed air supply and the other being connected to a vacuum. With the sockets laying on the work surface, vacuum pulls a socket into the tool nozzle. The tool is then placed into alignment with a hole and the trigger squeezed to activate the air supply to drive a ram which drives the socket out of the tool and into the hole in the board.
