The invention relates to a grounding switch static contact and a straight swing plug-in grounding switch, and the grounding switch static contact comprises an upper cylinder part which is internally provided with a static contact finger, and a lower guide cover fixedly arranged at the lower end of the upper cylinder part; one end of the guide channel is an open end, and the other end is a closed end; an elastic buffer piece is arranged at the closed end in a protruding mode, and the elastic buffer piece is arranged towards the guide channel and used for being in elastic jacking fit with a moving contact entering the guide channel in a swinging mode so that the moving contact can be buffered and decelerated. When the moving contact swings to enter the guide channel and moves to the end of the guide channel, the moving contact is elastically pressed and matched with the elastic buffer piece, and the elastic buffer piece buffers, decelerates and stops the moving contact, so that the moving contact is conveniently inserted into the upper cylinder part along a straight line in the next step, and is electrically connected with the static contact arranged inside. The moving contact is buffered by using the elastic buffer member facing the guide channel, so that the elastic buffer member with a proper elastic coefficient can be selected conveniently, and the installation is relatively convenient.

The invention relates to a connector and an insertion core assembly thereof. The insertion core assembly comprises an insulator, an insulation pressing plate and a metal end cover which are sequentially arranged in a front-back direction; the insulation pressing plate is fixedly arranged on the front side surface of the metal end cover so as to form a mounting base body; the insulator is fixedly arranged on the mounting base body; front power terminal holes and rear power terminal holes are correspondingly matched with each other and provided with power terminals in a limiting manner; front signal terminal holes and rear signal terminal holes are correspondingly matched with each other and provided with signal terminals in a limiting manner; a front grounding terminal hole and a rear grounding terminal hole are correspondingly matched with each other and provided with a grounding terminal in a limiting manner; the grounding terminal is conductively connected with the metal end cover; and corresponding wire passing holes for allowing power cables electrically connected with the power terminals and signal cables in signal connection with the signal terminals to pass are formed in themetal end cover. With the connector and the insertion core assembly thereof of the invention adopted, the insulation pressing plate, the insulator and the metal end cover can be relatively fixed after being assembled; and the insulator, the insulation pressing plate and the metal end cover can be fixedly assembled without a rear cover required.
