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 references (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.

A manually actuated ejector for electrical connectors for providing an initial disconnection movement between connector components includes a pivotal lever attached to one connector component having an actuator link connected thereto, the link terminating in a connection to a rotatable cam carried by the one connector part with a cam face in juxtaposition to an opposed surface of a second connector part whereby movement of the lever rotates the cam in opposition to the second connector part causing relative disconnection movement between the two connector parts.

Provided is an electrical connector for connecting a first electrical component to a circuit member having generally oppositely facing mating and remote surfaces and conductive regions on at least one of the mating and remote surfaces, at least one of the conductive regions being a through hole. The connector includes a dielectric housing having a receiving area for receiving the first electrical component therein and a plurality of terminal receiving cavities extending generally perpendicularly to at least one of the surfaces. The connector further includes a terminal in one of the terminal receiving cavities. The terminal has a body portion, a contact arm extending from the body portion for electrically contacting the first electrical component, a retention portion for retaining the terminal in the cavity, and a board contact extending from the body portion to the through hole. The board contact is a through hole-type tail for extending through the through hole. The tail includes a full segment and an abutting narrowed segment, each segment having edges and a centerline generally perpendicular to the mating surface, the centerline of the narrowed segment being offset from the centerline of the full segment. A transition between the abutting segments is positioned between the mating and remote surfaces of the circuit member when the connector is mounted to the circuit member.

Connector having terminals with improved soldier tails

An electrical connector is adapted for mounting on a printed circuit board. The connector includes a dielectric housing having at least one row of terminal-receiving passages. A plurality of terminals are received in the passages and include tail portions in a row for connection to appropriate circuit traces on the printed circuit board. The tail portions of some of the terminals in the row are adapted for insertion into holes in the circuit board. The tail portions of other of the terminals in the row are adapted for surface mounting on the circuit board. Tail portions of some of the terminals extend through holes in the tail aligner while enlarged cutout areas in the tail aligner accommodate the surface mount tail portions of the others of the terminals.

A SIMM socket with a metal latch for retaining a SIMM therein is provided. The socket includes a housing having a SIMM receiving slot and a plurality of terminals with contact beams extending into the slot. The SIMM is inserted into the slot in a first angular alignment with minimal insertion forces, and is rotated into a second alignment for achieving high quality electrical connection with the contact beams of the respective terminals. A metal latch is provided for releasably retaining the SIMM in the preferred angular alignment within the socket. The latch is stamped and formed from a unitary piece of metallic material and includes a housing engaging portion and a deflectable SIMM engaging portion. The housing includes walls for controlling the types and ranges of deflection that are permitted for the SIMM engaging portion.

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.

A connector assembly includes a stacked linear array of an alternating sequence of terminals and resiliently compressible insulator portions. The array is linearly compressed in an accordian-like fashion and is inserted in a housing having a cavity of length less than the uncompressed length of the array. The array is inserted in the housing and allowed to expand against opposing walls of the housing thereby maintaining the terminals in a self-compensating floating arrangement. A method for forming the connector assembly includes the steps of arranging resiliently compressible dielectric material between terminals to form a stacked linear array, linearly compressing the stacked linear array in an accordian-like fashion, inserting the compressed array in a housing, and thereafter maintaining the array in linear compression within the housing.

A new and improved heat-dissipating socket connector for connecting individual leads of a leaded module to individual circuits on a printed circuit board comprises a unitary molded dielectric frame including a module-receiving recess. The frame is cantedly mounted on the circuit board with the recess disposed at an angle with respect to the printed board surface. Compliant terminals are mounted in generally open terminal receiving cavities within the frame which are adapted to engage side portions of leads on an inserted module with high contact pressure in an anti-overstress manner. Openings within the frame together with an exposed terminal mounting arrangement, provide ventilation and airflow exposure for portions of the connector and module susceptible to the generation of high temperatures in use. The overall arrangement provides enhanced electrical reliability by reducing the possibilty of heat induced failures. The new and improved socket connector does not require increased board surface area and provides for full visual inspection for solder connections between connector terminals and printed circuits.

Heat-dissipating socket connector for leaded modules

A connector arrangement for electrically connecting circuit elements disposed on two printed circuit boards and spaced apart at centerlines of about 0.050 of an inch or less is described which includes a pitch controlling contact locator cooperating between the mating edge of an edge card and the connector housing. The pitch controlling contact locator includes a resilient supported spring member disposed in the connector cavity generally at the midpoint of the terminal array which is resilient in a vertical direction and substantially rigid in a horizontal direction. It further includes a mating cutout disposed in the mating edge generally at the midpoint of an array of contact pads which is adapted to engage the spring member with two points of contact when the edge card is inserted into the connector cavity. The pitch controlling contact locator effectively reduces lateral mating misalignments introduced in the arrangement by stacking of manufacturing tolerances and vertical mating misalignments caused by mother board warpage introduced by exposure to high temperature wave soldering processing.
