A socket connector configured such that elongated guide holes are formed in the housing so as to receive guide members of a device to be connected, and a slide member is attached to the housing to be slidable in the longitudinal direction of the elongated guide holes so as to restrict the guide members to their initial positions. The socket enables direct placement of the device on the housing, can shorten the projection length of projection terminals of the device, can facilitate positioning of the device to thereby enhance the easiness of attachment operation, can prevent bending of the projection terminals, can cope with an increase in density of the projection terminals, and has a simple structure.

Multiple small conductive and flexible hollow rings, each of which is made from a pliable material, provide a flexible connection medium for use between a substrate and a microelectronic device package. Each ring is formed to have at least one protuberance on the a ring's exterior surface. The protuberance has an apex or point, which when placed against a surface, will scrub or scrape the surface as the ring is compressed by a force acting on the ring radially. By scrubbing a contact surface with the apex, surface contaminants and layered material that might interfere with electrical signals can be removed.

Flexible scrub ring contact

Multiple small conductive and flexible hollow rings, each of which is made from a pliable material, provide a flexible connection medium for use between a substrate and a microelectronic device package. Each ring is soldered to both the substrate and the device. A portion of the sidewall of each ring is not soldered thus insuring that at least part of the ring stays flexible. The rings accommodate elevation differences on a substrate and electronic device package. They also provide a vibration resistant and flexible joint.

Flexible ring interconnection system

Multiple small conductive and flexible hollow rings, each of which is made from a pliable material, provide a flexible connection medium for use between a substrate and a microelectronic device package. Each ring is soldered to both the substrate and the device and held in place during manufacture by way of a flexible non-conductive film in which H-shaped cutouts are formed and into which a conductive ring is inserted. The interior sections of the H-shaped cutouts extend into the conductive rings and hold the rings in place during manufacture. A portion of the sidewall of each ring is not soldered thus insuring that at least part of the ring stays flexible. The rings accommodate elevation differences on a substrate and electronic device package. They also provide a vibration resistant and flexible joint.

A connector for mounting to a circuit board, includes a housing and a plurality of terminals arranged side by side at the predetermined pitch. Each terminal includes a flat base portion, a pair of contact members formed from a continuous folded-back portion that is folded back to one side of the flat base portion, and a carrier coupling section that is bent at substantially right angle to the opposite side of the flat base portion. The housing holds the terminals by an over-molding of the housing around the flat base portions of the terminals to form a generally flat plate-like housing. The pair of contact members of the terminal extends toward one surface of the dielectric housing and the carrier coupling section extends toward the other surface of the housing.

Low-profile connector for circuit boards

An improved press-fit pin having an elastically deformable area to be press-fitted in a selected through hole in a printed circuit board, the elastically deformable area comprising two parallel, opposite beams connected by an connecting deformable bridge thereby permitting the outer corners of each beam to engage the inner wall of the plated through hole while permitting the connecting deformable bridge to be deformed. The connecting deformable bridge comprises, in cross-section, an connecting flat section extending perpendicular to the opposite beams and two oblique sections extending outward from the opposite ends of the upper flat of the connecting flat section to be contiguous to the opposite beams The press-fit pin has a connecting flat section in its pressure-deformable area in place of the &ldquo;V&rdquo;-shaped area of a conventional press-fit pin, thus eliminating the necessity of forming acute angles in the die-and-punch.

A grounding grid having a substantially random geometric pattern is disposed on the opposite side of the substrate.

Grounded flexible printed circuitry with improved impedance characteristics

An improved electrical connector has a series of terminals arranged in two parallel rows in the connector housing, with the terminals being separated into upper and lower levels. The tail portions of the upper terminals have intermediate portions that are bent down to descend obliquely from the rear side of the connector housing while the tail portions of the lower terminals have corresponding intermediate portions that are bent up to rise obliquely from the rear side of the connector housing. The intermediate portions of the upper and lower rows of terminals meet with the solder tail portions of the tail portions along a common length so that the tail portions of both upper and lower rows have the same electrical length. The intermediate portions of both rows of terminals are also tapered, or flared along their length so that they have a larger surface area where they exit the connector housing than where they join to their associated solder tail portions. This tapering also assists in maintaining a desired impedance of the connector tail.
