Insulating plate mechanism used for rail transit connector

The utility model discloses an insulating plate mechanism used for a rail transit connector. A pin insulating plate used for the installation of pins comprises two pieces containing a pin front insulating plate and a pin rear insulating plate, the two insulating plates are connected and supported through a thread sleeve and a compression spring, the pin front insulating plate can move along the axial direction of the compression spring, the pin rear insulating plate is fixed on a plug housing through a screw and has a guiding effect, fibers and pins penetrate latches on the pin rear insulating plate through locating detents, when a plug is separated from a socket, heads of the pins do not protrude from the pin front insulating plate, and the pins are effectively protected, the pins can be matched with jacks conveniently, and the insulating plate mechanism used for the rail transit connector has a good application prospect.
