DEVICE TO PROVIDE ELECTRICALLY INSULATED CONNECTION BETWEEN TWO METAL PARTS Russian patent published in 2003 - IPC

FIELD: mechanical engineering. SUBSTANCE: proposed device is designed for insulating two metal elements of mainly tubular shape. Device contains first and second metal elements. First one contains enclosing conical surface. Second one has enclosed conical surface. One of two surfaces is coated with thin layer of insulating material. Two metal element are nested one into the other for mechanical connection. Angle of inclination of conical surface is 1-2^o. Sealing means are located practically on two edges of thin insulating layer. EFFECT: improved mechanical strength of connection. 1 dwg _
