Abstract: A coaxial connector in which the receptacle includes an outer shell that contains a sliding ring-shaped contact which is urged forwardly by a coil spring, the coil spring having a few turns at its rearward end which are firmly captured so that a low resistance connection is established through the spring. The receptacle also includes an inner tubular contact which is tapered to a minimum diameter at a throat region and which has slots forming resilient contact fingers, for receiving a tapered or straight pin-shaped plug member. In the case of a tapered pin-shaped plug member, the radius of curvature of the tubular inner contact at the throat thereof is precisely equal to the diameter of the pin-shaped member at the locations where they are engaged when the plug is fully inserted into the receptacle.

Abstract: A receptacle electrical terminal is mounted on a printed circuit board making a solderless electrical connection to one of the conductive strips thereon. The receptacle terminal includes a pair of mounting lugs which serve to lock it on the printed circuit board and a pressure contact surface which completes the electrical circuit from the conductor on the printed circuit board to the receptacle terminal when it is locked onto the circuit board.

Abstract: An electrical bus bar is disclosed which is formed of two parallel bars that lie together in juxtaposition in parallel planes except where conformations in one or both bars result in their separation to form a region into which a connector pin can be inserted. A means is provided for holding the two bars of the bus bar together so that they grip the connector pin after the pin is inserted into the connection position. Several means are disclosed for holding the bars together. The preferred means for that purpose is a non-conductive, resilient material which encompasses the two bars that form the bus bar and grips them together sufficiently to pinch the two bars against opposite sides of a connector pin with which they are assembled.

Abstract: An electrical connector for a data display, for example a gas discharge glass data display, provides a low cost connection between the display and a printed circuit board. The connector is designed as an elongate device having an arcuate lower rear surface which allows infinite connector positions within 90.degree. so that the contact tails of electrical contacts carried thereby can be bent to conform to a connector position which locates the data display at a desired angle with respect to a printed circuit board.

Abstract: A molded electrical jack housing adapted for mounting directly on a printed circuit board in which the electrical contacts are all inserted from one side of the housing and have connection lugs extending through the opposite side of the housing and in which the electrical contacts are formed from spring metal material and shaped to have tabs which rest on special plateau areas formed in the housing.

Abstract: An accessory for bridging the connection between two electrical conductor cords, which acts as a strain reliever and serves to keep the connection engaged.

Abstract: A multiple outlet connector cordset provides a plurality of three-wire receptacles connected to a single three-wire electrical line. Two or three outlets having locking or straight contacts are connected in parallel. The wires from the outlets are connected through sliding detachable terminals to blades extending from a plurality of parallel longitudinal connecting strips or bus bars. The strips are mounted within a premold rectangular support and have additional blades on the opposite side which connect through further terminals to the input wires. The premold and terminals hold the elements in position for a final molding operation. The entire assembly of receptacles, contacts, and wires, terminals, strips and rectangular premold is molded into a single integral outer insulation cover.

Abstract: An electrical grounding-type adaptor receptacle providing, from a standard duplex wall outlet, multiple circuits to accommodate a plurality of electrical plugs. The adaptor includes a wall plate or housing which has the configuration of a truncated pyramid and is adapted to overlie and completely conceal the outlet opening of the wall receptacle. Two pairs of parallel-connected conductive prongs protrude from the rear of the housing and are adapted to be inserted in the recess pairs respectively of the wall outlet for electrical contact with the circuits thereof. Carried by the housing are multiple three-conductor sockets for receiving grounding-type appliance plugs, the sockets being connected in parallel with one another and with the parallel-connected prongs.To provide the grounding function there is disposed within the housing an elongate conductor bar substantially in line with the sockets, the conductor bar having multiple spring fingers adapted to be engaged by the ground pins of the plugs.

Abstract: A connector for mounting DIP leads on pins extending from a circuit board includes an insulating body having a number of open sided recesses with a metal wall closing the sides of the recesses and folded cantilever springs extending from the walls into the interior of the recesses. Circuit board pins are seated in grooves in the bottom of the recesses from one side of the body and DIP leads are inserted into the recess from the opposite side of the body between the pins and springs so that the springs are stressed and hold the leads-in electrical connection against the pins.

Abstract: A connector for a small diameter towed sonar array is used to couple similar sections together. Each section includes a sheath or tubing of flexible plastic material such as polyvinylchloride clamped at each end tightly around a cylindrical metal coupling member having threads extending external of said tubing. Held adjacent the internal surfaces of the coupling members at the outside ends thereof are a pair of connector members which include a plurality of concentric conductor tracks. When adjacent sections are joined, these conductor tracks are pressed tightly together, partly as a result of the force exerted by flexible plastic spacers which abut against internal shoulders of the coupling members and the connector, urging the connector members outwardly against each other.

Abstract: A plurality of flat elongate flexible metallic strips are arranged in spaced parallel relationship within a length of flat flexible dielectric material so that the curled tubular ends of the strips are exposed at either end of the dielectric material to provide contact means thereat. Stiffening means which may comprise coined rib portions are interposed between the exposed tubular ends and the central portion of the strips to prevent flexing of the metallic strips at their juncture with each end of the dielectric material.
