Door opening solenoid for use in electrical door opener, has coil winding comprising two wire-insulated coil ends, where coil ends are provided with common insulation and are coated with free-flowing or brushable insulation material

摘要

The solenoid (10) has a coil winding comprising two wire-insulated coil ends (21), where the coil ends are provided with a common insulation. The coil ends are twisted with one another or lie parallelly adjacent to each other. The common insulation comprises an insulation material layer, which fixes the coil ends in a preset arrangement. The coil ends are coated with free-flowing or brushable insulation material. The coil ends are bendable and plastic deformable. The insulation material layer consists of acrylate compound i.e. urethane methacrylate, hardened by polymerization. Independent claims are also included for the following: (1) an electrical door opener comprising a door opening solenoid (2) a method for producing a door opening solenoid.
