METHOD OF MOULDING CABLE TERMINALS USING RADIAL PRESSING METHOD Russian patent published in 2009 - IPC H01R43/04 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering and is meant for use in permanent contact joints of electrical devices using radial pressing method of a cable or current conductor with a terminal electric contact, where there is need for provision of mechanical characteristics with a static load besides the required electrical parametres through the obtained joint. Deforming radial pressing is uniformly distributed on several deforming surfaces of an instrument with a given shape, repeating the shape of a deformed tip, installed such that, there is free discharge of excess metal, the deformation process ends when a given pressure value P is achieved, related to the maximum allowable P_max in the following relationship P_max>P>0.9 P_max The number of deforming surfaces is determined from a certain relationship between the external diametre D, of the tip and the number of the said surfaces N, and the radial width of one surface is calculated using a certain formula.

EFFECT: obtaining a connection which can support a static load of up to 90% ultimate tensile strength of the entire conductor, independent of dimensions and dimensional tolerance of work pieces, where there is possibility of moulding multi- and single-strand cables and conductors.
