Abstract: An electrical interconnection assembly is disclosed for use with high voltage devices such as traveling-wave tubes. The assembly includes an electrically insulating housing having a plurality of recesses formed in its outer and inner surfaces. Leads from the high voltage device can be connected directly to respective conductive pins mounted in recesses in the housing inner surface, and electrical conductors from a power supply can be connected directly to respective conductive pins mounted in recesses in the outer surface of the housing and which are electrically connected to respective conductive pins on the inner surface. Protruding staggered gripping elements on the housing outer surface and on a removable cover plate for the housing minimize the possibility of separation of electrical conductors from the conductive pins.

Abstract: A reusable cap encapsulates an electrical terminal in a junction box which routes communication lines such as phone wires. The cap includes a tubular body having a self tearing slot which receives a phone wire radially extending from a stud of a terminal. The cap also has an indicator knob having a pointed end which is angularly aligned with said self tearing slot. A technician can insert the cap over the terminal by aligning the indicator end of the knob with the phone wire, thereby aligning the self tearing slot with the wire. As the cap is inserted over the terminal, the wire penetrates and splits the self tearing slot. The cap is filled with a water impermeable elastic electrical insulating semi solid gel which encapsulates the terminal upon insertion of the cap. When the cap is removed, the gel is retained in the cap and cleanly pulls away from the terminal. A color coded indicator tab may be inserted onto the knob of the cap for indicating secured status of the phone wire.

Abstract: A low profile screw terminal block is provided with a split plastic barrel which serves to prevent screw stripout and to anchor the terminal screw when the terminal screw is pressed into the barrel and is advanced so as to form corresponding self-tapping threads in the smooth barrel, thereby to leave the terminal screw in a raised position ready for immediate wire insertion, to prevent the screw from vibrating loose during assembly and shipping and to securely hold the screw when the screw is tightened against a wire. The terminal block may be mounted to a fixed panel or like structure through the utilization of the split barrel at the end sections of the block by either a bolt running through the split channel and through the fixed panel or by a self-tapping machine screw inserted up through the fixed panel and into the split channel, with the split barrel design permitting overtightening without damage.
