Abstract: An electronic device including a casing, an optical fiber connector and a protecting cover is provided. The case includes an opening and a first engaging member. The optical fiber connector is disposed in the opening. The protecting cover is disposed at the opening and includes a second engaging member movably engaged with the first engaging member so that the optical fiber connector is exposed or shielded by the protecting cover. An optical fiber connector having a connecting port, a first engaging member and a protecting cover is further provided. The first engaging member is disposed besides the connecting port. A second engaging member of the protecting cover is movably disposed at the first engaging member so that the protecting cover exposes or shields the connecting port. The protecting cover is capable of fixing an optical fiber cable and shielding a light emitted from the optical fiber connector.

Abstract: A fixing bracket for signal connector adapted to fix a signal connector to a circuit board is provided. The fixing bracket includes a base, a fixing member protruding from a bottom surface of the base and at least two engaging sets protruding from a top surface of the base. The fixing member is adapted to pass through and interfere with the circuit board. Each engaging set includes a first restricting surface and a second restricting surface which are adjacent to each other and perpendicular to the top surface, and a third restricting surface parallel to the top surface. The two first restricting surfaces, the two second restricting surfaces and the two third restricting surfaces of the two engaging sets are used for respectively contacting two first surfaces, two second surfaces and two third surfaces of the signal connector so as to fix the signal connector.

Abstract: A method for assisting in focal length detection is applicable to a digital camera having the flash. The method includes the following steps. First, the flash of the digital camera is actuated and a first image is captured. Afterwards, a characteristic exposure value of the first image is calculated. A focus range comparison table is looked up according to the characteristic exposure value to obtain an initial focus position. Then, a focus procedure is performed according to the initial focus position to obtain a target focal length.
