Abstract: A surface mount electronic chip (10) is mounted on a holder (70) and electrically connected to holder terminals (74,76, 80) by the use of a carrier device (30). The carrier device has clips (36) mounted on walls of the carrier frame. The chip is merely pressed into a cavity (48) between inner tabs (44) of the chips. The carrier with the chip in place is merely pressed into a cradle (78) formed in the holder by the holder terminals, so outer tabs (46) of the clips press against the holder terminals.

Abstract: A shield is provided that blocks high frequency EMI (electromagnetic interference) from reaching circuitry that is connected to pins of a filter connector. The filter connector includes a plurality of pins (12) that extend through holes (92) in first boards (26), with each pin joined by a solder joint (90) to a signal trace (32, 60) that surrounds the pin hole. Filter components such as capacitors (40), each have one terminal (44) joined to a signal trace and another terminal (42) joined to a ground trace (30), with a gap (62) between the traces. Second boards (75) are provided that each lies facewise adjacent to a first board and that each carries a shield trace (72) that covers the gap between signal and ground traces. The pin-receiving hole in each second board has a circular portion and has a notch (100) therein though which a solder dispenser (102) can fit to dispense solder directly into the space between and on the pin and the signal traces.

Abstract: A wire (12) is bent into a row of contactors (14) that are each of miniature cloverleaf shape with each cloverleaf having a plurality of loops (21-24), the cloverleafs are then cut apart at cuts (40) to electrically isolate them from each other, and the middles of the cloverleafs are embedded into a block (43) of polymer. The combination of a row of cloverleafs and the block, are placed between upper and lower groups of terminals (30, 32) and compressed between them, to connect each upper terminal to a lower one.

Abstract: A high frequency coaxial cable having a foil (7a) between the cable insulator (5) and cable braid (7b), is terminated to a coaxial connector (40) in a manner that allows fast and easy cable preparation and results in a termination with minimal axial electric field lines that cause a high insertion loss and a high VSWR (voltage standing wave ratio). A bore (46) at the rear portion of the connector outer conductor, receives the cable insulator with foil around the cable insulator. The bore has a front part (54) that forms an interference fit around the foil, to avoid an axially-extending gap which might contain axially-extending field lines. The front of cable insulator and foil are flush and both abut the insulation (25) of the connector.

Abstract: A plug-and-socket connector (10) has a plastic housing (11) that holds electrical male or female contacts (14) in boreholes (16, 17) next to each other, and whose forward end forms a plug extension (13) or as a socket extension (113) and whose rear end receives and locks the male or female contacts (14) in the housing (11).

Abstract: A bayonet electrical connector has a spring loaded safety pin for locking the bayonet coupling. The pin projects into a recess, and a sleeve surrounds the part having the recess. The sleeve has a tab which projects into the recess, the sleeve being slidable to make the tab depress the pin against the spring bias of the pin, thereby to enable subsequent disconnection of the bayonet coupling. This design maintains a locking mechanism to prevent accidental decoupling of the bayonet connection, but makes the decoupling process simpler, by using, sliding of the sleeve and twisting to release the bayonet coupling.

Abstract: A fluid height sensor (10) includes a float (14) with an arm (20) fixed to a shaft (40) that extends into a cavity (30) in a housing (12). A switch assembly (32) in the housing includes a switch (50) formed by a largely stationary blade (52) and by a moveable switch blade (54) that moves forward (F) and rearward (R), respectively against and away from the stationary blade.

The activator (56) includes an activation blade (58) that is moved back and forth by the shaft, and a leaf spring (90) that extends in a loop between the outer ends of the activation blade and of the switch blade. The leaf spring compresses the switch blade by urging its outer end (74) towards its inner end (72), to cause the moveable blade to overshoot when it passes a center position in its forward and rearward movement.
