Abstract: A twist on electrical connector is provided, comprising a moulded thermoplastic cap and a wire coil insert therefore. The cap is a thin walled structure, and the coil is in substantially intimate contact along its entire length within the innermost, wire retaining portion, of the cap. A plurality of radially extending ribs, having substantial height and width, is formed on the outer periphery of the cap, at least in the upper portion thereof. The outwardly extending ribs provide a better finger grip, and are generally spaced apart such that the distance between any two adjacent ribs is below the 2-point threshold of discrimination for a human finger. The ribs permit better heat dissipation from the interior of the cap, in the event of heat build up therein; and the generally thin walled construction permits easy injection moulding techniques with relatively quick mould cycle times.

Abstract: The present invention comprises a solid composition having low magnetic signature. The composition comprises a plurality of high density, very low magnetic signature bodies or particles incorporated in a non-magnetic matrix of lesser density.
