Method for electrically insulating an electrically conductive wire end of an electrical wire, and mounting device for fixing a sleeve made of a flexible and electrically insulating material to a wire end of an electrical wire

A method for electrically insulating an electrically conductive wire end of an electrical wire, the method comprising:

• a) providing a mounting device having a base body with a through opening extending from a first outer side of the mounting device to a second outer side of the mounting device;
• b) introducing an end section of a tubular sleeve, made of a flexible and electrically insulating material, via the first outer side into the through opening and fixing the end section in the through opening by at least one fixing element;
• c) separating the fixed end section from a remainder of the sleeve by a cutting tool of the mounting device;
• d) introducing the wire end of the electrical wire via the second outer side into the through opening and inserting the wire end into an interior of the end section of the sleeve arranged in the through opening;
• and
• e) fixing the end section of the sleeve to the electrically conductive wire end.

A mounting device comprising:

• a base body comprising a through opening extending from a first outer side of the base body to a second outer side of the base body, wherein the through opening is configured so that an electrically conductive wire end of an electrical wire and an end second of a sleeve are introducible into the base body via the through opening;
• at least one adjustable fixing element configured to fix an end section of sleeve accommodated in the through opening;
• an adjustable cutting tool configured to separate the fixed end section from a remaining material of the sleeve;
• and
• a heating device configured to heat the end section of the sleeve,
• wherein the mounting device is configured to fix the sleeve, made of a flexible and electrically insulating material, to the electrically conductive wire end of the electrical wire.
