Abstract

Several electrical conductors (1) are maintained in place by joining them to neighbouring conductors at points where the potential of one of the conductors is equal to the potential of the other at the spot where they are in contact. The extremities of the conductors are held in electrical connecting devices (2, oe. The conductors may be spirally wound, each conductor looping with at least a neighbouring conductor, or may be in the form of a net with slanting weave. The conductors are joined to pairs of metal blades (2, 3) which are crimped and resistance welded together to secure the ends of the conductors. The blades are mounted on insulating supports (5, 6).
