ABSTRACT:
The present invention relates to a self-cleaning package testing socket, which comprises a base plate, a surround wall is configured on the periphery of the base plate and surrounding with a central testing tank inside. Two transversal channels respectively disposed at two opposite sides of the surround wall. Each transversal channel comprises a nozzle tube between inlet and outlet; the nozzle tube radially connects two bypass pipes. Herewith, the testing tank through the bypass pipes connected to the nozzle tubes of the transversal channels. Hence, when passing air into one end of the each transversal channel, it will cause the airflow rate inside the nozzle tube to speed up, so that the pressure inside the bypass pipes will reduce, and the testing tank results a vacuum-clean effect. Therefore, the present invention can be on-line self-cleaning the test socket.
