Be respectively arranged with stop part I and stop part II in fixed contact II, the stop part I and stop part II include being separately positioned on
First convex closure of fixed contact upper wall and the second convex closure in fixed contact underarm is set, wherein the first convex closure has when activity
The first of armature contact and fixed contact I, II exactly in contact with is still ensured that after end surface abrasion in the axial direction of fuse movement
Curved surface, second convex closure have still ensured that after the end surface abrasion in the axial direction of movable fuse movement movable fuse and
The second curved surface with gap between fixed contact I, II.
Further, the shell raises up to form a lug boss on position corresponding with axis.
Further, the only pressure gear is a tabletting made of resin material, and the only pressure gear is substantially in I-shaped
And one is formed to keep the framework of armature contact.
Further, the length of the only pressure gear and armature contact horizontal component arranged in parallel is more than armature contact
Length.
Further, the first surface and the second curved surface are arcwall face.
Further, the height of the first surface that first convex closure has to the first convex closure bottom is exactly equal to fixed touch
Height when point is contacted with armature contact, and it is very close to each other on the first surface of the first convex closure only to press gear to be just pressed on.
Further, the both ends of the armature contact are further opened with concave arc mouth and are transported to movable fuse with to avoid the first convex closure
Dynamic interference.
Further, several stop loss is additionally provided with when the movable fuse is axially moved and on the contact surface of end surface
Part.
The beneficial effects of the invention are as follows：The present invention adds one on armature contact and only presses gear to keep the state of contact,
And stop part is added in fixed contact, including compatible first convex closure is kept off with only pressure, it prevents because of the end surface in axial direction
The phenomenon worn and cause the contact force of armature contact and fixed contact larger may be damaged contact and the sense of touch of contact dropped
Low, stop part further includes the second convex closure, is supported due to preventing the abrasion because of the end surface in axial direction from leading to movable fuse uncontrolled movements
It is connected to the phenomenon that short circuit is caused in fixed contact, and movable fuse is provided with on the contact surface of the end surface in axial direction
Stop loss part, hence it is evident that the abrasion for reducing the end surface in axial direction greatly improves the performance of electromagnetic switch.
