Abstract: A floating electrical connector includes a housing with a tubular portion. An axis is defined in a center of the tubular portion. Several floating terminals are arranged around the axis and are partially connected. Each floating terminal has an inner terminal sheet on an inner side and a spring structure on an outer side. Each spring structure is connected to one of the inner terminal sheets. A portion of the inner terminal sheet is inserted into the tubular portion and arranged along an inner peripheral surface of the tubular portion. The portion of each inner terminal sheet located in the tubular portion has an electronic contact bulging inward. Several external pins are electrically connected around the floating terminals. When a conductive pin is inserted into the tubular portion, the spring structures could elastically deform, allowing the tubular portion to adapt to a horizontal deviation or a skew deviation of the conductive pin, providing a greater tolerance for alignment deviations.

Abstract: A powder allotting device comprises a supporting device, a coupling device, and a separating device. The supporting device is a base of the powder allotting device, and the supporting device is coupled to the separating device by the coupling device. The a separating device further comprises a rotary plate with a curved grooved structure, a plurality of movable valves, a scraper, and a cylinder with a plurality of T-shape grooves, and a plurality of slices. The plurality of slices are inserted into the T-shape grooves and enter the curved grooved structure, moving up and down the T-shape grooves.

Abstract: A scraper and a plurality of slices are allocated on a powder allotting device. For achieving the matter of uniformly allocating powder, the present invention utilizes the scraper and the plurality of slices for scraping and separating powders.
