Abstract:
An interconnection system suitable for transmission lines, in the form of electrical or optical conductors, or in the form of conduits for electrical waveguide transmission, reflected light or fluidic signals, wherein lengths of such transmission lines bridge between discrete point-to-point location on a substrate, the transmission lines beng anchored by sealant and filler material at selected substrate locations and being cut generally transversely, or otherwise transversely formed, to provide exposed conductor or conduit end portions anchored at the selected locations. The transverse areas of the conductors or conduits defined by such transversely cut, or otherwise transversely formed, and exposed end portions provide energizable signal energy planes. More specifically, such discrete energizable planes in the form of transverse conductor surfaces, are of a size and shape conforming to the transverse conductor areas exposed by cutting or other forming operation. Such conductors may be either insulated electrical or optical conductors provided thereover with metal or a metallized coating to result in an electrical shielded, or an optically shielded and reflecting, interconnection system. The transmission lines in the form of conduits provide discrete, end-anchored conduits for conveying signal energy excitations in the form of fluidic pressure, reflected optical energy or electrical waveguide transmissions. The ends of the conduits are anchored in the substrate and define generally transverse end openings of the conduits. The transverse areas of such openings provide energizable signal energy planes through which the conveyed signal excitations are transmitted. The size and shape of the energizable signal energy planes conform to the conduit transverse end areas exposed by cutting.
Abstract:
The invention relates to a terminal and a method for terminating an electrical wire therein. The terminal employs a wire barrel having a asymmetrical pattern of cavities into which the wire is extruded. The method provides optimum electrical contact through high level deformation and maximum tensile strength through low level deformation.
Abstract:
A plurality of electrically conducting socket-type terminals are provided on a common carrier strip. The sockets comprise sleeves of conducting material which contain a resiliently expansible receptacle which forms a female terminal. Each receptacle is freely expansible internally of a corresponding sleeve. This is accomplished by providing a pair of opposed spring arms of the receptacle which are free to deflect resiliently toward and away from each other internally of a corresponding sleeve. Positive connection between a corresponding sleeve and a receptacle is accomplished totally externally of the receptacle in order to prevent undue constraint of its resilient expansion. Such a connection is accomplished by providing a tab integral with a non-deflectable portion of a receptacle, the tab projecting outwardly of the receptacle for connection to the enclosing sleeve. The free ends of the spring arms protrude outwardly of the sleeve to provide an enlarged flared entryway to the receptacle. The free ends are also exposed to allow visual inspection of their correct alignment. The ends are further widened to provide relatively large target surfaces for receiving and funneling the male electrical terminal which is to be connected within the receptacle.
Abstract:
The invention relates to a miniature connector having a dielectric housing which is flexible for conforming to irregularities in the printed circuit board. A plurality of contacts are mounted in the housing. Each of the contacts includes a leaf spring portion in the form of a cantilever beam integral with the base portion and latched to the housing. The housing includes an opening at one end allowing for receipt of projecting posts mounted to a printed circuit board. When the housing is mounted on the surface of the printed circuit board the posts are electrically attached to the base portions of the contacts. The housing includes additional openings for pluggable receipt of male electrical terminals wedgingly engaged between the posts and leaf springs which cooperate to engage and grip the terminals.
Abstract:
A terminal is disclosed which includes an inner sleeve portion adapted to receive a conductive lead inserted therein and an outer sleeve portion surrounding the inner sleeve portion with the sleeves arranged, relative to parts of the device which connect to other terminals, to permit a welding operation providing a weld of improved characteristics. In one embodiment for use in terminating aluminum wire the inner sleeve is made of aluminum and the outer sleeve is made of a different material such as a copper base metal alloy to provide a connection of dissimilar materials. A heat sensitive insulating sleeve is used to provide a seal of conductive interface and wire support, the sleeve being actuated by the heat of welding transferred through terminal sleeve portions.
