Abstract: A tamper respondent enclosure including (a) a circuit board; (b) an enclosure surrounding the circuit board; (c) a tamper respondent sensor having (i) a substrate with first and second sides; (ii) a first layer of conductive traces on the first side; (d) wherein the tamper respondent sensor is wrapped around the enclosure with at least one overlap region; and (e) wherein only at the at least one overlap region the tamper respondent sensor has a second layer of conductive traces on the second side. Preferably, the substrate is insulating and made of opaque PET, and the first layer is adjacent the enclosure.

Abstract: The present invention relates to a tamper respondent enclosure which may be opened and closed as many times as necessary. In particular, the present invention relates to a re-usable tamper respondent enclosure comprising a first sensing means and a second sensing means wherein the first sensing means detects any attempt to breach the enclosure or to compromise the second sensing means.

Abstract: A buckling beam type electrical connector is provided which is operable to selectably protect the contact ends of the buckling beam elements from physical damage.

Abstract: An electrical connector system includes a housing, at least one electrical cable assembly, at least one retaining member and a resilient locking member. The housing has formed therethrough at least one retention window and at least one shaped aperture which is formed through a rear portion of the housing. The at least one retaining member is dimensioned to substantially mirror the dimension of the at least one shaped aperture. The at least one retaining member has an internal surface which defines a channel portion having a predetermined diametral dimension. The channel portion terminates to a slot. The at least one retaining member snap-fittingly engages an individual at least one electrical cable. The at least one electrical cable and the at least one retaining member are insertably received by an individual shaped aperture. A resilient locking member is made integral with each at least one retaining member.

Abstract: A high-density coaxial interconnect system for connecting an array of closely packed coaxial cable connectors to an electrical signal transmission system while maintaining a ground-shielded signal path through the interconnect system components from coaxial cable to the board.

Abstract: A miniaturized high-denisty coaxial interconnect system for use in termination of coaxial signal cables to electrical signal transmission systems is provided. The system contains one or more grouper modules having a staggered array of receptacle grooves in which the grouper modules are housed within a grouper frame. The system is easy to assemble and provide easy attachment and detachment from the transmission system. This invention also provides for an increased density of signal cables with improved spacing due to the unique design of component parts and their arrangement within the system.

Abstract: A ribbon coaxial cable having precisely spaced conductors and drain wires separated by a dielectric spacer, conductor and spacer shielded together, and units jacketed to give cable having wires exactly positioned for termination.

Abstract: A right-angled header for attaching a multiplicity of coaxial electric cables, either separately of together in a flat cable, to a printed circuit board, the signal circuit of the header being internally shielded from interfering outside signals and from each other within the body of the header.
