Abstract: A tuning mechanism for tuning a resonant circuit is provided. The tuning mechanism comprises a spring pin having a superconductive, dielectric or magnetic tuning tip attached thereto. The spring pin is slidably inserted into a filter package wall through a mating hole. A mechanism is provided for adjusting the position of the tip within the electromagnetic field above the filter element. The tip may be shaped, thus allowing adjustment of both the height of the tip above the filter element and the position of the tip in a plane parallel to the plane of the filter. Optionally, the spring pin may include an offset to allow close spacing of the tips along with wider spacing of the actuator end of the pin.

Abstract: An apparatus for connecting a high density cable assembly having a shield and to be connected to corresponding contact pins provided on a substrate having a grounding grid formed of conductive guides, each having a predetermined number of contact pins therein, including a connector to which the cable assembly is connected and which is to be mounted to the associated guide. The connector has a connector body, a connector cover surrounding the connector body, and a latching device provided between the connector cover and the connector body for easily latching and unlatching the connector to and from the associated guides.

Abstract: A semiconductor chip module for a semiconductor chip having an exposed front face with a two dimensional array of contacts is disclosed. A connector plate is located proximate the front face of the chip. The connector plate has a plurality of apertures which correspond to and are aligned with the contacts of the semiconductor chip. A plurality of transmission elements are located proximate the connector plate opposite from the semiconductor chip. A plurality of flexible conductors extend through the respective apertures of the connector plate. The flexible conductors are electrically coupled to the contacts of the chip and to the transmission elements.

Abstract: A versatile cardedge receptacle comprises an insulative housing (10) having contacts (16,18) with one or more cantilevered contact beams (20) and one or more cantilevered parallel retention arms (22) and/or lateral shoulders (36,38) with bearing surfaces (50,52) for application of seating force necessary to press-fit install a discrete (preassembled) receptacle into a wiring panel (72) in a single step. The bearing surfaces (50,52) are positioned colinearly with their respective press-fit terminals (26,28), and can be accessed by the seating tool (56), either internally through the card slot (12) or externally from the sides (62) of the housing. The undersides of contact shoulders (36,38) can be used to facilitate forcible extraction of the entire connector from the wiring panel (72) with a footed tool (77).

Abstract: For mating with a tubular female contact 12, a male contact 10, has two cantilevered arms (16, 18) extending from its body portion 14. The arms are each formed of sheet metal and each has a convex mating surface near its tip which faces outwardly, away from the other arm. The arms may have equal or unequal lengths, may be displaced laterally in the plane of the sheet metal, and may be shaped so that the tips either contact or are spaced when mated. In a preferred embodiment, the ends of the arms have a complementary stepped configuration 50 to reduce the volume of the contact's mating portions; the resultant narrower end portions of the arms, as well as the convex mating surfaces further down on the arms, may both mate with the female contact, providing two points of contact on each arm.

Abstract: Versatile card-edge or other types of connector receptacles comprise contacts with one or more bowed cantilevered primary contact arms (tines) 26 and one or more cantilevered parallel arms 28 for insulator mounting, both sets of arms extending in a common direction from a common body portion 24. The secondary contact arms (tails) of the contacts may extend from the bottom 44 (horizontally or vertically) or the sides of the contact 36. The mounting arms may have barbed or pointed retention surfaces 32 on either their inside or outside edges and the contacts may be installed into either the top or the bottom of an insulator housing 10. The bowed contact tines may have installation shoulders 34 extending over the top of the insulator housing to provide bearing surfaces for press-fit installation. The connectors may have a zero-insertion-force feature, whereby a spreading bar 78 may be inserted between the bowed tines 26 to pre-spread them for ease of male mating member insertion.

Abstract: A connector of the type including an aperture for receiving a circuit board includes a base retaining a row of longitudinally spaced contacts. The contacts include flexible portions adjacent one end. A camming bar is seated in the base for longitudinal sliding movement and for swinging movement about a longitudinal axis. A contact actuating member is mounted on the camming bar and is engageable with the contacts. The base and the camming bar include cam means responsive to longitudinal sliding movement of the camming bar for swinging the camming bar and the contact actuating member about the longitudinal axis. In this manner, the flexible portions of the contacts are displaced from the circuit board-receiving aperture to facilitate entry or removal of the circuit board. The base includes a socket within which the camming bar is seated, to form the longitudinal swinging axis of the camming bar.

Abstract: High contact density post and blade electrical receptacles for edge-mount semiconductor packages or like substrate carried circuits comprise an insulator housing retaining a plurality of contacts having substantially planar construction and providing redundant electrical connections with the mating post or blade.

Abstract: A high contact density connector system for an edge-mount semiconductor package or a like panel member having densely spaced contact means provided along an edge comprises two mating connector parts, each having a one piece insulator housing retaining a plurality of contacts having mating means arranged in a single row. The contacts are assembled into the insulator housings by parallel positioning a plurality of such housings and assembling a transversely positioned row of such contacts into corresponding positions of all housings.

Abstract: This disclosure is directed to a connector unit which has the capability of mating a plurality of side by side insulated conductors (usually in the form of a multiconductor, flat, flexible, bonded or laminated cable) with a plurality of similarly spaced contact pad areas on a printed circuit board (PCB). The multi-conductor cable is mated to the PCB in a quick-connect manner and enables also a quick-disconnect, or separation of the cable assembly, from the PCB, to be accomplished with one hand only, and with no tooling required. The resulting contact pressure between the PCB and the leads of the multi-conductor cable is above a certain predetermined minimum and is reproducible, even after repetitive quick-connect and disconnects of connector unit from the PCB. The mating of the connector unit to the PCB is accomplished with low insertion force. Further, the connector unit is capable of electrically engaging a PCB of varying thickness.
