Title:
STATIC CONTACT OF GROUNDING SWITCH, AND STRAIGHT-SWING PLUG-IN TYPE GROUNDING SWITCH
Document Type and Number:
WIPO Patent Application WO/2022/121361
Kind Code:
A1
Abstract:
The present invention relates to a static contact of a grounding switch, and a straight-swing plug-in type grounding switch. The static contact of a grounding switch comprises: an upper cylinder part provided with static contact fingers therein; and a lower guide housing fixed at the lower end of the upper cylinder part, wherein one end of a guide channel is an open end, and the other end thereof is a closed end; and an elastic buffering member is arranged on the closed end in a protruding manner, and the elastic buffering member is arranged towards the guide channel, and is used for being in elastic press-fit with a moving contact that swings into the guide channel, thereby buffering and decelerating the moving contact. When the moving contact swings into the guide channel and moves to the end of the guide channel, the moving contact can be in elastic press-fit with the elastic buffering member, the elastic buffering member buffers and decelerates the moving contact, and stops same, and then, the moving contact can readily move upwards in a linear manner and be plugged in the upper cylinder part, so as to be conductively connected to the static contact fingers provided in the upper cylinder part. The elastic buffering member facing the guide channel is used for buffering the moving contact, and an elastic buffering member with a proper elastic coefficient can be easily selected and can also be easily mounted.
