Abstract: A ceiling fan blade assembly structure includes a blade holder, multiple fan blades, and multiple locking assemblies. Multiple fan blade assembly portions are disposed at an outer side of the blade holder. Each fan blade assembly portion includes two first side plates parallel to each other, a first radial positioning portion, and two first vertical positioning portions disposed on the two first side plates. Each fan blade has a fan blade connection portion that includes two second side plates, a second radial positioning portion, and two second vertical positioning portions. The second and the first radial positioning portions are engaged with each other, and the two second and first vertical positioning portions are engaged with each other. Accordingly, the fan blade connection portion is preliminarily positioned on the fan blade assembly portion. Through the locking assembly, the first and the second radial positioning portions are locked together.

Abstract: An electronic label device for an electronic shelf label system includes a display module, a driving chip and a system circuit board. The display module includes a driving substrate and a display medium arranged on the driving substrate. The driving chip is arranged on the driving substrate and is electrically connected with the driving substrate. The driving chip controls the display module to display images. The driving chip includes a switch circuit. The system circuit board is electrically connected with the driving substrate and the driving chip. The system circuit board includes a main controller and a light-emitting element, which is electrically connected with the switch circuit. The main controller transmits a control signal to the driving chip, and the driving chip controls the switch circuit, based on the control signal, to drive the light-emitting element to emit light.

Abstract: A connector combination includes a transmission line and a connector. The transmission line includes a woven shield for providing a signal reference of a radio-frequency signal, and blocking noise to prevent the radio-frequency signal from being interfered with the noise. The connector is coupled to the transmission line, includes a pipe, wherein a soldering area is formed on the pipe for allowing the woven shield to be soldered with the pipe after the transmission line is combined with the connector.
