High temperature solenoid actuator

摘要

A solenoid actuator includes a housing, a bobbin assembly, a coil, and a washer. The bobbin assembly is disposed at least partially within the housing, and includes a return pole and an armature. The return pole is fixedly coupled to the housing, and the armature is axially movable within the housing. The coil is disposed within the housing and is wound around at least a portion of the bobbin assembly. The washer is disposed between the coil and a portion of the bobbin assembly and surrounds a portion of the return pole. The washer is formed of an electrical insulator material.

1. A solenoid actuator, comprising:
a housing; a bobbin assembly disposed at least partially within the housing, the bobbin assembly including a return pole and an armature, the return pole fixedly coupled to the housing, the armature axially movable within the housing; a coil disposed within the housing and wound around at least a portion of the bobbin assembly; and a washer disposed between the coil and a portion of the bobbin assembly and surrounding a portion of the return pole, the washer formed of an electrical insulator material, wherein:
the washer includes a first end surface, a second end surface, an outer circumferential surface between the first and second end surfaces, and an inner circumferential surface between the first and second end surfaces;the first end surface has a circumferential groove formed therein; anda portion of the coil is disposed in the circumferential groove.
