Connector seat, connector and connecting mechanism

The embodiment of the utility model provides a connector seat, a connector and a connecting mechanism. Two ends of a positioning depression are provided with a guide wall in an extension way, and the end surface of the guide wall is a slope; the positioning depression is arranged on the side wall of the guide wall, and the end surface of the guide wall is provided with an opening; and the end surface of the guide wall forms guiding surfaces at two sides of the opening. When the embodiment of the utility model is in use, the connector is inserted into the connector seat and rotates, and a positioning protrusion slides into the positioning depression under the action of the end surface of the guide wall during rotation. With the connector seat, the connector and the connecting mechanism of the embodiment of the utility model, the positioning protrusion can smoothly slide into the positioning depression through the assistance of the guide wall, so that visual measurement of builders is unnecessary to align the positioning protrusion and the positioning depression, the positioning protrusion can smoothly slide into the positioning depression through insertion and rotation with any angle, thereby reducing the difficulty in mounting; and the embodiment of the utility model facilitates the connection especially in a dark or bad working environment.
