Rarely measures are taken on the contact structure of the relay to improve the vibration resistance to reduce the jitter, and as a result, the damping effect is limited.

本发明的动静触点结构可互换，如圆锥型结构，动触点可做成凸圆锥型，静触点可做成凹圆锥型，也可二者相反。斜面与动静触点中轴线角度α可按不 同应用、材料选定。当触点接触时，一定会存在抖动，而抖动是动静触点因弹跳在很短距离内非接触造成。在很短的距离内，因是斜面接触，且动静触点及材料均有一定的弹性，从整个接触面来看，一部份不接触，而另一部分接触，而对动静触点两端而言，只要有一个接触点接触，则整个状态为接触，处于接通状态。这样，如在很短距离内的抖动，动静触点两端，就可以一直维持接通状态，即减少或消除了很短距离内的抖动。利用本发明的触头结构，可制造出微抖动或无抖动的继电器。The dynamic and static contact structure of the present invention is interchangeable, such as a conical structure, the movable contact can be made into a convex conical type, and the static contact can be made into a concave conical type, or vice versa. The angle between the inclined surface and the static and dynamic contact axis can be as follows With the application, material selection. When the contacts are in contact, there must be jitter, and the jitter is caused by the non-contact of the moving contact at a short distance. In a short distance, because of the oblique contact, and the dynamic and static contacts and materials have a certain elasticity, from the perspective of the entire contact surface, one part does not touch, and the other part touches, and the two ends of the moving static contact In other words, as long as there is a contact point contact, the entire state is contact and is in an on state. Thus, if the jitter is within a short distance, both ends of the dynamic and static contacts can be maintained in an on state, that is, the jitter within a short distance is reduced or eliminated. With the contact structure of the present invention, a micro-jitter or jitter-free relay can be fabricated.
