Patent ID: 7235991

Claim:
An insert having an independently movable latch mechanism for loading a semiconductor package, comprising: an insert body having a pocket; latch units installed at opposite sides of the pocket, the latch units for preventing a loaded semiconductor package from escaping out of the pocket; and a press plate elastically installed above the insert body, the press plate operating the latch units by movement relative to an upper surface of the insert body; each of the latch units including, a latch movably connected to the insert body near to the pocket such that a first end of the latch is rotatable around a fixed shaft pin and a second end is movable into and out of the pocket at a lower portion of the pocket, the latch having an front surface slanted downwards towards the center of the pocket and a guide hole near to a back surface, which is opposite to the front surface; a button connected with the latch through a moving shaft pin, the moving shaft pin being rotatably located in the guide hole parallel to the fixed shaft pin, the button being elastically coupled between the latch and the press plate, the button projecting upwards from the insert body and converting movement of the press plate into rotational movement of the latch by causing movement of the moving shaft pin along the guide hole such that the latch rotates about the fixed shaft pin, and the guide hole including a guide hole correction space that permits movement of the latch towards the moving shaft pin such that the latch rotates about the fixed shaft pin independent of the movement of the press plate; and an elastic body disposed between the back surface of the latch and the insert body; the elastic body applying an elastic force to the latch so as to protrude the second end of the latch into the pocket.
