METHOD AND DEVICE FOR SEALING THE AREA OF CONTACT SECTIONS OF ELECTRIC WIRE CONNECTIONS Russian patent published in 2020 - IPC H01R4/04 H01R4/22 

FIELD: electricity.

SUBSTANCE: invention relates to a method of sealing the area of contact sections (01), including at least one contact section on electric wire connection (02). Technical result is achieved by the fact that wire connection (02) includes at least one electric wire (03) and at least one conducting element (03, 12, 14), electrically connected to conductive connection. Heat-shrinkable sleeve (07) is put on surface of contact sections (01) on the section of first zone (08), on both sides overlapping area of contact sections (01) in longitudinal direction, after which heat shrink sleeve (07) is heated to shrinkage temperature. During heat shrink sleeve (07) heating additionally performing induction heating of electric conductor (04) at least in area of contact sections (01), due to which hot-melt adhesive inside heat-shrink sleeve (07) and (or) on surface of contact sections (01) is heated to melting point.

EFFECT: proposed method and device for sealing contact areas with at least one contact point of electric wire connections, providing improved sealing, including for complex wire connections and wires with large cross section, as well as along with sealing in sealing position ensuring tightness in longitudinal direction, id est inside multiwire core.
