Movable contact module, movable contact assembly, movable contact device and contactor

A movable contact assembly for a contactor, comprising:

• a movable contact module including:
• an insulating member having:
• an insulating body having a through hole penetrating therethrough;
• and
• a peripheral wall protruding from the insulating body and surrounding an opening of the through hole;
• and
• a movable contact having:
• a fixed portion fixed in the insulating body;
• and
• an exposed portion exposed from the insulating body, the fixed portion of the movable contact surrounded by the insulating body;
• a drive shaft passing through a through hole in the insulating member, the drive shaft is elastically connected to the contactor movable contact module and driving the movable contact to move between a closed position in electrical contact with a static contact and an opened position in electrical separation from the static contact, the movable contact being electrically isolated from a drive shaft passing through the through hole, and the peripheral wall of the insulating member increasing a creepage distance between the drive shaft passing through the through hole and the exposed portion of the movable contact;
• a first snap ring that is snapped in a first snap groove formed on one end of the drive shaft, and resting against the top surface of the insulating body;
• and
• a first spring compressed between the bottom surface of the insulating body and a radial flange formed on the drive shaft.

A movable contact module, comprising:

• an insulating member, including:
• an insulating body having a top surface and a bottom surface opposite to the top surface in a thickness direction, and defining a through hole;
• and
• a peripheral wall protruding from the insulating body and surrounding at least one open end of the through hole, the peripheral wall including:
• a first peripheral wall protruding from the top surface of the insulating body and surrounding a top opening of the through hole;
• and
• a second peripheral wall protruding from the bottom surface of the insulating body and surrounding a bottom opening of the through hole;
• and
• a movable contact having a first portion arranged within the insulating member, and a second portion exposed and extending from the insulating member, the fixed portion being at least partially surrounded by the insulating member and adapted to be electrically isolated from a drive shaft passing through the through hole.

A movable contact module, comprising:

• an insulating member, including:
• an insulating body having a top surface, and defining a through hole;
• a peripheral wall protruding from the insulating body and surrounding at least one open end of the through hole;
• and
• isolation walls protruding from the top surface of the insulating body and extending along width and thickness directions of the insulating body, the isolation walls located in an inner cavity surrounded by the peripheral wall and separated from the peripheral wall in a radial direction of the through hole;
• and
• a movable contact having a first portion arranged within the insulating member, and a second portion exposed and extending from the insulating member, the fixed portion being at least partially surrounded by the insulating member and adapted to be electrically isolated from a drive shaft passing through the through hole.
