AI Technical Summary

Technical Problem

The electrical connection between the wiring harness of the existing electromagnetic actuator and the coil is located outside the coil, resulting in a huge connection and difficulty in sealing, which may lead to contamination and movement of the coil and the housing.

Method used

A solenoid assembly is designed in which the connecting portion of the wire coil is located in the coil housing, the wire is connected to the coil through the opening of the coil housing, and is sealed in the opening of the core by a bushing to suppress rotation of the coil housing.

Benefits of technology

A more compact design is achieved, reducing the risk of contamination and improving coil and housing stability, avoiding the assembly complexity and cost increase in traditional designs due to prominent electrical connectors.

Abstract

The invention relates to a driveline component comprising an electromagnetic actuator with an integrated wire connection. A solenoid assembly for a rotary power transfer device includes a core having an internal cavity, a wire coil received within the internal cavity, and at least one wire via which power is provided to the wire coil. And a connecting part between the at least one lead and the lead coil is positioned in the inner cavity.
