The ground may be a conducting sheath, forming a shielded transmission line.

A term referring to kind and/or favorable conditions that cause little or no effect or degradation on an item; a controlled environment.
The alloying and hardening of copper with the addition of the metal beryllium. This alloy is used extensively for electrical contact base metal because of its hardness and ability to withstand numerous flexures without relaxation or loss of its spring constant.
Bifilar Contact (TWINAX)
Assembly of three contact consisting of two inner contacts arranged paralled to one another with the third contact peripheral to, and encircling the two inner contact, enabling termination of screened twisted pair cables.
A hermaphroditic connector containing fork-shaped mating contacts.
Pertaining to lengthwise slotting of a flat spring contact used in printed circuit card edge connectors.

A fixed terminal of the type to which conductors are connected by means of mechanical compression.
A defect in stranded wire where the strands in the stripped portion between the insulated covering wire and a soldered connection (or an end tinned lead) have separated from the normal lay of the strands.
The time interval between the successive like edges of the clock signal (rise to rise or fall to fall). This is the reciprocal of the clock frequency.

A connector assembly in which the components are bonded together using an electrically appropriate adhesive in a sandwich like structure to provide sealing against moisture and other environment, which weaken electrical insulating properties.
A cable or strap that provides an electrical path for the purposes of providing a current path for safety and/or shielding grounds, to prevent shock or spark hazards, and to provide a low impedance path for EMI/RFI.
A device used to connect exposed metal to ground. It normally carries no current, but is used as a current path to eliminate shock or spark hazards and insure the operation of circuit protective devices in the case of breakdown.
A protective covering or connector accessory, usually made of a flexible or semi rigid insulation material, designed to house wire/cable terminations as a protective device, facilitate harness direction, and provide a moisture seal when bonded or used as a potting form.
An electrical connection between a wire and a sharp-cornered post in which the wire is laid parallel to the length of the post and adjacent to its wider face. The wire is secured to the post by tightly wrapping several turns of a separate solid wire around the post and the wire to be secured. Each turn of the wrapping wire contacts the bound wire producing deformation in it and also locks on at least two corners of the post.
