METHOD FOR MANUFACTURING A TULIP OF CONTACTS AND TULIP OF CONTACTS CARRIED OUT ACCORDING TO THE METHOD.

摘要

P Process for the manufacture of a tulip of contacts from a blank made of a tube of material having good conductive properties and good elasticity comprising a thinned portion provided with longitudinal parallel slots and terminated by a ring of material having good electrical conductivity and good resistance to the effects of the electric arc, characterized in that it comprises the following operations: BR/ - placing said blank (1) around a cylindrical core (10) having a diameter substantially equal to the diameter of the blank and a length equal to that of the blank, the top of the core abutting on the crown, BR/ - there is arranged around the blank and right of the slots a block (5 ) of annular section having an inner diameter slightly greater than the outside diameter of the blank and a height substantially equal to that of the slots, the block being made of an elastomeric material, BR/ - one exerts on the end surfaces of said block a pressure tending to reduce the inside diameter of said block until the desired slot width is obtained. / P
