Abstract
Manufacture of electrical trunking containing, in a metal enclosure, a set of parallel electrical conductors supported at regular intervals on insulative contact blocks. A single sheet metal blank is bent and crimped to produce a tubular profile with joined edges 27, 28, the conductor assembly 31 is then slid into the tube and each support contact block 30 is centered in a respective branch opening 18 using a tool inserted through the opening. The contact block is clamped against the opening by an elastic expansion device.
