Abstract: An electrical multiconnector of a zero insertion force type comprises a plurality of elongated conducting connector elements extending from an insulating base in generally parallel relation and adapted to be engaged with conducting pins of a mating connector assembly to establish electrical paths therebetween. Each connector element includes a slider arranged thereon for longitudinal movement therealong to its engaging position and away from its engaging position. An actuator plate is provided for reciprocal movement in a direction parallel to the direction of elongation of the connector elements between a disengagement position, to allow the sliders to disengage the connector elements whereby the pins may be inserted or withdrawn without the necessity to exert any force, and an engagement position, to urge the sliders to conductively engage the connector elements with respective pins.

Abstract: A high density, zero-insertion-force electrical circuit board connector is provided comprising an insulator body having walls defined in part by reciprocally movable cams. Contacts with offset terminal portions are arranged in close-packed array and are simultaneously cammed into the closed position by cam followers mounted in a reinforced insulator housing.

Abstract: A multiple contact connector has an elongate actuating member which is reciprocally mounted in a housing holding the contacts, the contacts in one or more linear arrays. On longitudinal reciprocation of the actuating membert it is also caused to reciprocate up and down in a direction normal to the longitudinal direction. In so doing it pushes on the contacts, deflecting them sideways. The connector is then assembled or inserted, after which the actuating member is moved to release the contacts. A substantially zero insertion force is obtained.

The securement mechanism comprises (i) a row of notches in each cell wall; (ii) a locking projection on one wall of each module; (iii) a slotted locking bar along the rearward edge of each cell wall exterior spaced away from the cell cavity; and (iv) a wedging wall on one wall of each module near the rear thereof snugly receivable through the slot of the locking bar.

Abstract: A novel electrical connector structure having integrally molded plastic construction with a first premold core and a second integrally molded external shell separated by metallic foil or stamping. Plastic spring-clips of integral plastic formation are also provided with dual notches thereon one for direct engagement with a matching connector and the other a mounting panel or bracket. Concurrent connection of the connector to a matching connector and to a panel or bracket is made possible in which the matching connector is independently attachable or detachable from the connector with respect to said panel or bracket. The spring-clips are of such a compressible configuration such that when compressed the spring-clip deforms or deflects from its original configuration, and upon release of external pressure, it tends to revert back to its original disposition.

Abstract: In a connector in which a plug connector is held in a cover, locking members are mounted on the cover, and when the plug connector is engaged with a receptacle connector the locking members automatically engage locking pieces of the receptacle connector to lock the connectors in an engaged state, the plug connector is entirely housed in the cover for release levers of the locking members used for unlocking. The locking pieces of the receptacle connector are formed integrally with the body of the connector and each is fitted into a square reinforcing frame formed integrally with the flange of a metallic shell of the receptacle connector, by which the locking pieces are mechanically reinforced.

Abstract: A chip connector which includes conductive contacts which electrically contact the carrier. The contacts include an outwardly extending cantilevered projection to allow the contacts to be shifted outwardly on downward engaging movement of the connector top to allow insertion or removal of the chip. The connector base includes a wall positioning part which biases the contacts into a preloaded or clamped position.

Abstract: Apparatus for coupling multi-conduit drill pipes to maintain arcuate registry between connected pipes, and for transferring the drive torque of one drill pipe to the next drill pipe. One end of one drill pipe (50) includes drive lugs (100) matable with corresponding drive recesses (102) in the end of the next drill pipe (52). An index lug (104) in the drill pipe end, different that the drive lugs (100), is matable with a corresponding index recess (106) in another pipe end ot maintain arcuate registry of the coupled pipes and thus longitudinal alignment of the respective conduits (30) throughout the drill string. An internally threaded coupling collar (84) with different thread pitches at each end thereof is threadable onto the joined lug and recess mated drill pipe ends to hold the pipes mated. The joined pipe ends respectively include external threads (88, 90) of pitches corresponding to that of the coupling collar (84) so that a differential thread action draws the pipes together.

Abstract: An electrical interconnection assembly is disclosed for use with high voltage devices such as traveling-wave tubes. The assembly includes an electrically insulating housing having a plurality of recesses formed in its outer and inner surfaces. Leads from the high voltage device can be connected directly to respective conductive pins mounted in recesses in the housing inner surface, and electrical conductors from a power supply can be connected directly to respective conductive pins mounted in recesses in the outer surface of the housing and which are electrically connected to respective conductive pins on the inner surface. Protruding staggered gripping elements on the housing outer surface and on a removable cover plate for the housing minimize the possibility of separation of electrical conductors from the conductive pins.

Abstract: An integral elastomeric sealing member for an electrical connector assembly mountable to a panel has a transverse gasket section and an axial seal section extending rearwardly from an aperture through the gasket section. The gasket section is compressed between a mounting face of the receptacle and the panel, and the axial seal section extends along the inside of the plug-receiving cavity thereof and has an inner dimension just less than the outer dimension of the plug section of the plug connector which it seals around when the plug is in mating engagement with the receptacle. A tapered portion around the plug section acts as a camming surface to gently deform the axial seal section outwardly against the cavity wall, while the gasket section is held firmly between the panel and the receptacle connector.
