Abstract: According to the present invention, an electrical plug connector is mountable onto a panel member for matable connection with an electrical receptacle connector mounted on another panel member when the panel members are moved relative to one another. The plug connector includes a mounting member for mounting to the panel member and it has a hole therein. A plug body member includes a contact section, a terminating section and an intermediate section; the intermediate section is disposed in the hole, and the hole has a diameter larger than the intermediate section.

Abstract: An electrical contact member comprises a conductive plate (4) having therein a slot (5) open to an edge of the plate (4), the slot (5) having a mouth (28) at the edge of the plate (4) and leading to a first inwardly tapering section (29) which leads to a second parallel straight sided section (30), the second section (30) leading into a third inwardly tapering section (31) having convex converging sides leading to a throat (32) which opens into a fourth outwardly tapering section (33) leading into a fifth inwardly tapering section (34) having convex converging sides, the maximum width of the fifth section (34) being less than that of the third section (31), the fifth section (34) defining a closed end (35) for the slot (5). When used with a conductor (100) having a stranded core the slot shape of the contact serves to retain the strands in as near as possible their original relative positions, thus ensuring reliable connection.

Abstract: In a packaging means for packaging together a light source or detecting means, a lens, and an optical fiber there is provided a sleeve for holding the light source/detector at one end of the sleeve and the lens at the other end to form a lens package. To hold the lens package there is provided a housing having first and second cavities opening onto each other and separated by shoulder means. The optical fiber is positioned in the first cavity with its end just short of the shoulder means. The lens package is retained in the second cavity with the lens abutted against said shoulder means with its focal axis aligned with the axis of the optical fiber and further with the tolerance error of the distance between said lens and the end of the optical fiber being determined largely by the variations in radius of said lens and variations in the position of the end of the optical fiber.

Abstract: A contact for use in printed circuit boards in which a portion thereof is split or sheared to form at least a pair of legs for insertion into an aperture in said circuit board with the adjacent legs each having a surface which face and abut each other in the shear plane therebetween and with said legs being offset with respect to each other in said shear plane. When the offset legs are inserted in an aperture in a circuit board they are forced towards each other along the shear plane with the facing surfaces experiencing a strong component of force normal to said shear plane. Such normal force in turn produces a large frictional force between said facing surfaces which, together with the spring-like force generated as the legs are forced together, produce a strong opposing force against the walls of the aperture.

Abstract: A rotating collar lock connector for terminating the end of a coaxial cable in which all of the metal parts therein are either stamped and formed or drawn, as opposed to being machined. Further, since no solder is required and since assembly is accomplished entirely from one direction the connector can be assembled at a single rotary type assembly machine. The connector comprises a rear metal sleeve which receives the coaxial cable at a first end thereof. A rotatable metal collar has a flanged first end which is slipped over the first sleeve from the second end thereof until it abuts against protuberances formed on the surface of the first sleeve near said first end. A metal spring means, such as a spring washer, is then slipped over the first sleeve up to said collar flange.

Abstract: A card cage for holding printed circuit cards comprising modular cage elements each having a pair of parallel slots formed therein and spaced apart a distance to slidably receive the edges of a printed circuit card and to retain said card therein. The said modular elements are stacked together, one upon the other, to form the card cage with each module having contact retaining cavities formed in the corners thereof. Securing means in the form of conductive rods or bolts extend through the corner edges of the stack of card holding modules to supply the required power supply voltages into the card cage system and also to secure together the stack of modules. Such conductive rods are exposed to the cavities in the ends of the modules. Individual contact means retained in the cavities connect the rods or bolts to conductive areas on the corners of the individual printed circuit cards and thereby supply the power voltages to said cards.

Abstract: A connector means for connecting together two optical fibers whose ends have been stripped of optical cladding to expose the cores. The connector comprises means for gripping the fibers at unstripped sections thereof with a predetermined length of fiber extending from datum or reference surfaces on the connector such that the ends of the stripped fibers face each other and are spaced apart a very short distance of the order of not more than one and one-half times the core diameter. The connector further comprises a pair of elastomeric elements each with grooves of semi-cylindrical cross-section formed therein that fit together to form a cylindrical bore which retains the stripped ends of the two fibers. Because the diameter of the cylindrical bore is less than the diameter of either core retained therein, the resilient walls of the cylindrical bore will give way and will thereby force the ends of the two cores into substantial concentric alignment.

Abstract: A connector means for terminating a ribbon-type cable consisting either of plurality of single conductors or a plurality of coaxial cables and comprising a connector housing having a flat main body portion with at least one partially closed channel formed on each side thereof and oppositely positioned with respect to each other. A contact means has its first end retained within each of the partially closed channel portions and its second ends extending outwardly therefrom and comprising a plate-like element extending away from the flat main housing body and having a slot formed therein which opens onto that edge of the plate-like elements which is farthest from the flat main housing body. A wire from the ribbon cable is placed over the slot in each slotted plate-like terminal. A pair of wing-like elements are pivotally connected to the partially closed single channels and constructed to pivot toward each other and over the plate-like elements of the contacts and thereby force the wires into the slots.

Abstract: A three-position pneumatic tool having a toggle trigger for actuating a control rod which in turn controls a pair of pneumatic check-valves. Three interconnected, tandemly arranged piston assemblies are operatively associated with an air pressure source at one end while also being operatively associated with a work assembly at the other end. The trigger is spring-biased to a location wherein the tool is in a neutral workpiece engaging position. Actuation of the trigger in one direction will open one of the pneumatic valves whereupon air pressure acts upon the upper surface of one of the pistons so as to lower or retract the tool to a workpiece insertion position. Release of the trigger permits the tool to attain the workpiece engaged or neutral position. Rotation of the trigger in the opposite direction permits the other pneumatic valve to open whereupon air pressure acts upon the lower surfaces of all the pistons so as to raise and actuate the tool to the operating position.

Abstract: A bus bar of laminar construction useful for power distribution systems and the like is disclosed with a method of fabricating the bus bar and installing suitably provided contact pins or posts. The method comprises stacking conductive plates and dielectric plates alternatively, encapsulating the conductive and dielectric plates in a solidifiable dielectric medium, drilling apertures through the medium and specified conductive plates, driving the pins and an amount of solidifiable material provided therewith into the apertures and into contact with the conductive plates, and solidifying the solidifiable material to secure the pins in the apertures.

Abstract: The disclosure relates to electrical connectors positioned between adjacent printed circuit boards for interconnection therebetween. The terminal arrangements on each printed circuit board are predesigned for compatibility with the connector to be used.In accordance with the first embodiment of the connector, a zero insertion force connector is positioned over outwardly extending pins from the printed circuit boards and is then locked to the pins by a camming action within the connector. In accordance with the second embodiment, the connector is formed in male and female halves, contact to the board by the connector being by means of a normal force engagement against pads on the printed circuit board. Extensions of lines to further adjacent printed circuit boards is provided by way of additional connectors of the same type mounted in the same manner.

Abstract: A low profile DIP socket comprising a block-shaped housing with two parallel rows of box-like contact retaining cavities therein and with a rib extending from the inner side wall of each cavity. A DIP lead retaining contact is retained in each cavity and has a generally U-shaped configuration with a first of the two free ended legs having an extension on the free end thereof which is bent back into the channel of said "U" and towards and adjacent to said second leg. A tab is sheared from the bottom of the U-shaped contact and also the first leg thereof to form a slot in said bottom and said first leg thereof and into which said rib fits to orient and stabilize said contact. The tab extends from the closed end of the second leg and through an aperture in the bottom of the cavity in the housing for wire wrapping or other type connection purposes.

Abstract: A metal clip for connecting an insulated wire and a terminal post together without stripping the wire or solder. The clip is generally channel-shaped with a first slot means extending across the bottom wall of the channel and into the side walls of the channel. Extensions of the free end of the side walls are folded within the channel back towards the bottom wall and have second slots formed therein which are aligned with the first slot means. The conductor is inserted into the first and second slots and then the terminal post is pushed into the channel at right angles to the wire and adjacent the bottom wall thereof to force the conductor farther back into the slots and causing the edges of the slots to either grip or cut through the insulation and into the wire, thereby making a good electrical and mechanical connection.

Abstract: A female contact particularly useful as a low profile contact inserted in a printed circuit board and comprising a tubular portion with a flared open end for receiving a male pin. A pair of opposing contact fingers extend from the flared open end and are folded back upon themselves to extend downwardly into the interior of the tubular portion. Near the open end of the tubular portion the two opposing fingers are initially close to, and substantially parallel to, the walls of the tubular portion. As they extend further into the tubular portion, the curved fingers extend away from the walls of the tubular portion and towards each other, with their concave surfaces facing each other. As a terminal post is initially inserted between the fingers the fingers are deflected apart and outwardly towards the walls of the tubular portion so that a point on said fingers will be forced against the wall of the tubular portion.

Abstract: Leading portions of individual wires of a plurality of wires are positioned in spaced apart relationships with respect to each other by a wire separating mechanism which utilizes a template having a generally planar surface with a primary groove defined therein capable of substantially accommodating a trailing portion of each of the wires in a bunched together condition and a plurality of secondary grooves defined therein which emanate from the primary groove along separate, spaced apart paths, each of the secondary grooves capable of substantially accommodating therein the leading portion of only one of the wires. A clamp on the mechanism located near one end of the primary groove holds the trailing portions of the wires within the primary groove in their bunched together condition. A roller element mounted on the mechanism and having a cylindrical surface is moved by the mechanism into engagement with the trailing portions of the wires so as to introduce compressive forces thereon.
