Abstract

Improvements in the formation of an insulating encapsulation, on electrical components equipped with connection pins where the component is arranged in a mold provided with openings through which the end portions of the pins pass and into which the plastic material is injected into a mold. Mold cavity defined between the external surface of the component and the internal surface of the mold, characterized by comprising a tubular sheath (6; 12; 14) that encircles, at least, the portion of each pin (2) that passes through the mold. The cavity of the mold (5), said sheath having a length such that axial compression of the sheath occurs when the electrical component is arranged in the mold and the latter is sealed, so that it seals said portion of the plug passing through. Of the mold cavity in front of the plastic molding material. (Machine-translation by Google Translate, not legally binding)
