The invention discloses a hot-plugging type interface connector comprising a cage body for accommodating an insulation body and a plurality of conductive terminals installed on the insulation body. The cage body is installed on a mounting circuit board and is provided with elongated plugging openings for butt joints with plug modules. The cage body includes a main body part being a die casting/lathing part and a frame opening part being hardware arranged at the front end of the main body part. Buckling holes and buckling pins that can be buckled mutually are arranged between the frame openingpart and the main body part. Because the cage body is assembling unit formed by the hardware and the die casting/lathing part and the hardware is buckled to the die casting/lathing part main body partby the buckling holes and the buckling pins, the consistency of the frame opening part dimension and the frame opening part dimension of a common hot-plugging type interface connector is realized.
