Abstract
In the supporting structure of fixed contact terminals, a pair of fixed contact terminals with respective fixed contacts provided on their free ends are supported by fixed contact bases and the both ends of a movable contact piece contact with and separate from the pair of the fixed contacts. Cut-off grooves are provided on the surfaces of the fixed contact bases at each position near the fixed contacts, and they are formed in a converted T shape on a cross section, partitioning the pair of fixed contact terminals.
Claims3
A supporting structure of fixed contact terminals comprising:
- a pair of supporting bases supporting basements of a pair of fixed contact terminals with respective fixed contacts provided on free ends thereof;
- and
- a movable contact piece disposed inside the pair of supporting bases, both ends of the movable contact piece configured to contact with and separate from the pair of the fixed contacts, wherein
- a protruding portion is formed on each of the pair of supporting bases,
- an insulation groove is formed on a lower portion of a side surface of each of the supporting bases perpendicular to a top surface of each protruding portion, proximate the fixed contacts so as to partition the basement of the pair of the fixed contact terminals, and
- the insulation grooves provide a larger gap between the side surfaces of the pair of supporting bases than a gap at portions of the side surfaces without the insulation grooves.
