Abstract
The utility model relates to an electrical connector identification mechanism for identifying whether an electrical connector is connected in place. The identification mechanism comprises a connection cap which is rotatably sleeved onto the periphery of a corresponding housing. The connection cap comprises a front connection cap and a rear connection cap which are in axial disengagement prevention matching. The connector further comprises an inner ring which is sleeved onto the periphery of the housing for transmitting torque between the front connection cap and the rear connection cap. The inner ring is provided with a rear connection cap matching structure which is in rotation stop axial sliding matching with the rear connection cap, and the inner ring is further provided with a front connection cap matching structure for being in rotation stop axial insertion matching with the front connection cap. The connector is further provided with an elastic element which is used for applying a forward acting force to the inner ring so as to cause the front connection cap matching structure to be axially inserted into the front connection cap in a rotation stop manner. The inner ring is further provided with a bearing surface which is extended into an annular cavity and used for bearing the backward thrust of the insertion end of a corresponding adapter connector so as to cause the front connection cap matching structure to be disengaged from the front connection cap when the adapter connector is inserted. The objective of the utility model is to provide a simple-structure connector whose connection position can be identified so as to determine whether the connector is connected in place.
