IPC: H01R33/76
Filed: 1993-05-20
Abstract: PURPOSE:To protect an LSI against terminal short circuit and to protect the inner terminal of an IC socket against the influence of external force by detecting a bent terminal of the LSI before the LSI is mounted on the IC socket thereby retraining the LSI from shifting when it is secured to the IC socket body. CONSTITUTION:When an IC socket upper cover 1 is opened, a board 5 is pushed up through the action of a spring 6 thus setting a terminal guard 4 above the inner terminal 3 of an IC socket. A part 7 of the board projects from the right and left sides of an IC socket body 2 so that it comes into contact with an upper protrusion 8. A part of the board has same height as the surface of the body 2. Furthermore, the terminal guard has an inclining end. When the upper cover 1 is closed, protrusions at four corners of the upper cover push a part of the board in body 2 thus pushing down the board. The terminal guard is also pushed down simultaneously, but the height thereof is equalized to that of the inner terminal 3.
