ABSTRACT:
In an example embodiment, an insert having an independently movable latch mechanism for loading a semiconductor package may include an insert body having a pocket, latch units installed at opposite sides of the pocket, and a press plate elastically installed above the insert body. The latch units prevent a loaded semiconductor package from escaping out of the pocket. The press plate may operate the latch unit by movement relative to an upper surface of the insert body. Each latch may be movably connected to the insert body such that a first end of the latch is rotatable around a fixed shaft pin. A second end of the latch may be movable into and out of the pocket. The latch may have a front surface slanted downwards towards the center of the pocket and have a guide hole near the back surface, opposite the front surface. A button connected to the latch by a moving shaft pin may be elastically coupled between the latch and the press plate, the button projecting upwards from the insert body and converting the movement of the press plate into rotational movement of the latch by causing the moving shaft pin to move along the guide hole. The movement of the shaft pin rotates the latch about the fixed shaft pin. The guide hole includes a guide hole correction space that permits movement of the moving shaft pin into the guide hole correction space such that the latch rotates about the fixed shaft pin independent of the movement of the press plate. An elastic body may be located between a back of the latch having the guide hole and the insert body near to the side of the latch, such that the elastic body applies an elastic force to a latch so as to cause the latch to protrude into the pocket.
