Also be provided with partition between deformed plate and fixed cover, described partition is iron-nickel alloy.
The utility model has the advantage of:
(1) make the line contact become the face contact, the contact plate of face contact spring is with to be touched the thing surface suitable, make the face contact spring and be touched thing surface face and contact, contact plate is long-pending large, deformed plate is evenly distributed in pressure on contact plate, the face contact spring is evenly distributed the active force of contact, has avoided being touched the distortion of thing.
(2) lower end of contact connects as one by connecting portion, can satisfy the distortion of 1-2mm, has reduced the once welding with wire, has improved the reliability of contact, and solder joint has also reduced contact resistance when reducing.
