Abstract

The utility model provides a connector shell with a limited inserting depth. The connector shell comprises a frame body part, wherein a terminal main body is wrapped and clamped in the rear end of the frame body part, and blocking shoulders are arranged at the inner side of the frame body part, in front of the terminal main body and at a path where a plug is inserted. In the utility model, as the blocking shoulders are arranged at the inner side of the frame body part of a connector, in front of the terminal main body and at the path where the corresponding plug is inserted, the corresponding plug can be blocked by the blocking shoulders, and cannot go deeper into the frame body part when being inserted to a certain position of the frame body part, so that the terminal main body is prevented from loosening or backward movement caused by the impact of the terminal main body due to the excessive insertion of the plug.
