1. A clip for a fuse-holder for a fuse cartridge comprising;
- two lugs extending from a base and spaced to define a space for receiving a fuse cartridge therebetween with circular cross-section, said lugs (21, 22) being folded in directions (A21, C21, D21, A22, C22, D22) parallel to a central axis (X1) of the cartridge when seated between said two lugs such that they have two electrical and mechanical spaced lines of contact (21a, 21d, 22a, 22d) for engaging and supporting a radial surface of the fuse cartridge in such a manner that portions of said lugs intermediate said spaced lines of contact are spaced outwardly from the radial surface of the fuse cartridge when the fuse cartridge is seated between said two lugs, said spaced lines of contact of said two lugs being parallel to and on opposite sides of the axis of the fuse cartridge when the fuse cartridge is positioned therebetween, and wherein traces of said two electrical and mechanical lines of contact (21a, 21d, 22a, 22d) in a plane perpendicular to the radial surface of the fuse cartridge when seated between said lugs are included in a sector which is centered on a trace or the central axis (X1) in a sector plane, with an apex angle (γ
) less than 30°

Abstract
A fuse-holder clip including two lugs designed to define a space for receiving a fuse cartridge with circular cross-section. The lugs are folded along lines parallel to a central axis of the cartridge when the cartridge is placed in the clip such that each lug forms two electrical and mechanical lines of contact for engaging and supporting the cartridge with the two lines being globally parallel to the axis.
