The technical scheme for realizing the utility model is as follows: a functional test device of an I/F converter comprises a tool bottom plate, an IC socket, a radiating fin and a rectangular connector; the tooling bottom plate is a PCB and is a double-sided printed circuit board, and the tooling bottom plate is provided with IC sockets which are arranged in a single row and are arranged in parallel in opposite directions; the IC socket is provided with radiating fins which are detachable and are flatly paved on the IC socket; and the tail end of the wiring of the double-sided printed circuit board is connected with the tooling bottom plate by adopting a rectangular connector.

The surface of the radiating fin is provided with a strip hole.

The pressure resistance of the tool bottom plate, the IC socket, the radiating fins and the rectangular connector is more than or equal to 220V;

the highest working temperatures of the tool bottom plate, the IC socket, the radiating fins and the rectangular connector are all more than or equal to 150 ℃;

the IC socket is a gold-plated IC chip socket;

the rectangular connector is a bending-inserting type connector.

The utility model has the following beneficial effects:

the gold-plated IC chip socket has good contact performance and conductivity, good chip elasticity, convenient product insertion and extraction, and greatly reduces the phenomena of bending of product lead legs, insulator damage and the like caused by difficult insertion and extraction. The aluminum profile heat radiating fin has the advantages of very high heat conduction efficiency, strong corrosion resistance, difficult deformation and long service life. The heat emitted in the product test is more effectively conducted to the radiating fins and then emitted to the surrounding air through the radiating fins, so that the condition that the product performance is unstable due to poor heat dissipation of the product is eliminated.
