Abstract: An improved connector for orthogonally mounting circuit boards. The preferred embodiment of the present invention includes 40 female contacts which protrude from the two coplanar triangular surfaces. An additional 40 male contacts are located within channels in triangular projections. Further, the preferred embodiment of the present invention has an additional 16 leaf contacts located adjacent to the inner walls of the triangular projections. Each leaf contact protrudes from the inner wall of the triangular projections and comes into electrical contact with a corresponding leaf contact of a mating connector as the leaf contacts of each connector slide past one another.

Abstract: A pad array socket for use in mechanically and electrically connecting a high density pad array integrated circuit carrier to a printed circuit substrate. The socket comprises a flexible circuit, a molded elastomeric spring member, a frame, and a cover. The frame defines a cavity. The elastomeric spring member is placed at the bottom of the cavity. The flexible circuit is placed directly over the elastomeric spring member. An integrated circuit carrier is placed into the cavity upon the flexible circuit. The cover is then secured over the assembly, thereby applying downward pressure on the integrated circuit carrier. The spring member applies upward pressure to the flexible circuit, thereby causing the electrical contacts of the flexible circuit to come into contact with the electrical contacts of the integrated circuit carrier.

Abstract: A low insertion force, high contact force, electrical contact system, for use in a disk drive unit or printed circuit board, comprised of a socket contact and an insertion pin. The socket contact is provided with a mating region and a retention region. The mating region is formed of two independent opposed cantilevered contact beams embossed with contact dimples on their inwardly facing surfaces for engaging electrical pins. The cantilevered contact beams extend away from the retention region toward a pin-receiving end, and are angled inwardly toward each other to form a "flask" shape. Constant insertion forces are maintained on an insertion pin by the frictional forces produced by the embossed contact dimples. With a pin fully inserted into the socket contact, efficient mechanical and electrical contact is achieved by virtue of the compression and torsional forces produced by the independent cantilevered contact beams.

Abstract: A low-profile dual-beam female electrical connector contact for electrically interconnecting components of an electrical system. The contact includes a contact body, cantilevered contact beams, retention flanges, and a solder tail. The contact body is a generally rectangular-shaped structure. Lateral extensions near the middle of the body attach the contact beams to the body. Each contact is generally rectangular and extends from the point of attachment toward the distal end of, and parallel to, the contact body. The retention flanges are located near the distal end of the contact body, and extend from edges thereof. Since the contact beams and the retention flanges are contained within the height of the contact body, the overall height of the contact is reduced.

Abstract: Lubricant additives are produced by reacting an alkoxylated amine with phosphorous acid. The additives preferably also contain a boron moiety which is reacted with the phosphorous acid and amine, preferably in a one step reaction. More preferably, a mono-functional alcohol or a long-chain aliphatic carboxylic acid is added to this mixture. The additives are particularly useful in metal working oils and particularly as extreme pressure additives to replace the currently used chlorinated paraffin additives.

The additives preferably also contain a boron moiety which is reacted with the phosphite and amine, preferably simultaneously in a one step reaction. The additives are particularly useful in metalworking oils and particularly as extreme pressure additives to replace the currently used chlorinated paraffin additives.

Abstract: A method for connecting the wires of a high density, flat transmission cable to a connector is provided. A crimp connector for facilitating the practice of the method is also provided. The connector includes one or more rows of contacts mounted thereto. Each contact includes a crimp section extending from the connector housing. The crimp sections are plated with a relatively thick layer of solder. After stripping the end of the cable, selected cable conductors are inserted within the crimp sections. A batch crimping operation secures the conductors to the contacts, after which the crimp sections are heated to fuse the solder. Once the solder has cooled, a reliable connection will be established between the cable and connector. A solder-plated bus bar may also be secured to selected cable conductors by preliminarily mounting the conductors thereto and then heating the bus bar.

Abstract: A zero insertion force connector assembly is provided for allowing the electrical connection of a flat, flexible cable having conductors therein and a printed circuit board. The assembly includes a plastic housing having spring contacts arranged in parallel configuration. The housing is secured to the printed circuit board by the tail ends of the spring contacts. A cover plate is pivotably and slidably mounted to the housing. An end of the cable may be inserted between the cover and housing when the cover plate is pivoted to an oblique position with respect to the housing. The cover plate is then pivoted towards the contacts and moved rearwardly to lock it in the closed position. The housing and cover plate include mutually engaging components which effect such locking upon sliding the cover plate towards the housing.
