An electrical connection device has an electrical connector and a sealing member. The connector has an insulating housing which has an abutting face. The sealing member is provided to the housing and is adapted to be abutted between the face and a panel of an electronic device. The sealing member has an annular body, two first annular ribs, a plurality of second annular ribs and a plurality of positioning posts. The annular body has first and second surfaces and a plurality of penetrating holes penetrating the first and second surfaces. The first annular ribs respectively protrude from the first and second surfaces, and are adapted to respectively abut the panel and the face. The second annular ribs respectively protrude from the first and second surfaces, encircle the penetrating holes respectively, and are adapted to abut the panel and the face.

Electrical connection device

An electrical connector comprises an insulative housing and a plurality of conductive terminals. The terminals are respectively provided in grooves of the housing. Each terminal has a portion fixed to the housing, an upper elastic portion extending from a top end of the fixed portion and a lower elastic portion extending from a bottom end of the fixed portion. The upper portion has a first arm extending from the fixed portion, a first contact section extending from the first arm, extending out of a top surface of the housing and bending, and a second arm extending from the first section, and a distal end of the second arm abuts against abutted structures in the corresponding groove when the first section is pressed down.

An aerated swirling vertical shaft with double volute chambers comprises an upper volute chamber () and a first shrinking section () beneath the upper volute chamber (), a venting passage () outside the upper volute chamber (), a vertical shaft section () beneath the first shrinking section (), as well as an aerated lower volute chamber () and a second shrinking section () communicated with the aerated lower volute chamber () between the first shrinking section () and the vertical shaft section (), wherein the upper end of the aerated lower volute chamber () is connected with the first shrinking section (), the lower end of the second shrinking section () is connected with the vertical shaft section (); the upper end of the venting passage () is communicated with the atmosphere and the lower end is communicated with the aerated lower volute chamber (). The water stream in the vertical shaft can be discharged smoothly and the wall surface of the vertical shaft may avoid being destroyed due to cavitation and cavitation erosion.
