Abstract:
An assembly auxiliary jig facilitates assembly of an electronic device having a casing, a first fitting, a second fitting, and a wire. The assembly auxiliary jig includes: a base having therein a receiving space for positioning and receiving the casing and an accessing recess configured to communicate with the receiving space and facilitate access to the casing; a first platform disposed at the base and having a positioning groove in communication with the receiving space to thereby receive the first fitting; a first lid hinged to the first platform and configured to close the positioning groove; a second platform disposed at the base and defined with a positioning recess in communication with the receiving space to receive the second fitting; and a second lid hinged to the second platform and configured to close the positioning recess.
Abstract:
A device and a method for locking and calibrating a frequency is provided for receiving a precise external clock frequency to lock an adjustable oscillator that controls an oscillation frequency to a predetermined frequency. The device comprises a process unit and a frequency adjusting unit. The process unit is provided for comparing the oscillation frequency with a precise frequency to generate a frequency difference and a calibration signal according to the frequency difference. The frequency adjusting unit generates a locking voltage according to the comparison result of the calibration signal and the internal oscillation frequency for locking the oscillation frequency of the external adjustable oscillator to the predetermined frequency, so that the adjustable oscillator still can output a precise oscillation frequency without requiring a precise oscillator.
Abstract:
A protective device is applicable to a casing provided with a first coupling portion and configured for use with an outdoor communication apparatus. The protective device includes a body and a shielding portion. The body is configured to shield the front of the casing and provided with a second coupling portion coupled to the first coupling portion. The shielding portion is laterally provided to the side of the body for shielding the casing sideways. Hence, the shielding portion of the protective device shields the casing from direct irradiation of sunlight, prevents the outdoor communication apparatus from being overheated, and protects the outdoor communication apparatus against rainwater and dirt. A casing configured for use with an outdoor communication apparatus and equipped with the protective device is further provided.
Abstract:
An optical fiber adapter fixing element applicable to the coupling of an optical fiber adapter and a panel of an optical fiber communication network apparatus includes a hollow hood having a first coupling portion and a second coupling portion. The hollow hood has an assembling side and an opening side adjacent to each other and having an acute angle there between. The second coupling portion is configured to be coupled to the panel. The optical fiber adapter fixing element does not occupy any space attributable to a circuit board provided in the optical fiber communication network apparatus and protects users against harm which might otherwise occur to the users when the users look directly at laser exposed from the optical fiber adapter.
Abstract:
A fixing structure for a battery positions the battery in a casing of an electronic device. The fixing structure includes at least a connecting portion, at least a locking portion, and a receiving portion. The connecting portion is on one side of the battery and with a waterproof element. The locking portion is on the other side of the battery and is opposite to the connecting portion. The receiving portion is on the casing and with a first inserting portion and a plurality of second inserting portions. The first inserting portion and the second inserting portions correspond in position to the connecting portion and the locking portion respectively. Hence, the fixing structure protects the electronic device against permeation of water and ensures secure positioning of the battery.
Abstract:
A modular keyboard includes an upper casing, a lower casing corresponding to the upper casing, an electric conduction element and a circuit board. The upper casing includes a first side and a second side opposite to each other, and a plurality of press keys disposed on the first side. The lower casing is set for sealing the second side, and an enclosure space is formed between the upper casing and the lower casing. The electric conduction element is installed on the second side in the enclosure space, and the circuit board is installed between the electric conduction element and the lower casing. With a supersonic welding technique, the upper casing and the lower casing are engaged with each other to seal the enclosure space and isolate the electric conduction element in the enclosure space and the circuit board from the exterior.
Abstract:
A fixing device includes a housing, a bezel, and a rib structure. The housing has a first side. The bezel is connected to the housing for covering the flat structure with the housing. The bezel has a second side and a third side. The rib structure is disposed outside the flat structure and is located between the first side of the housing and the second side of the bezel for keeping a gap between the second side of the bezel and the flat structure.
Abstract:
A communication apparatus includes a housing and an electronic device installed in the housing. The housing has a shell body having a top wall, a front wall and a mounting zone defined by a part of the top wall and a part of the front wall, and a cover coupled to the mounting zone. The mounting zone is provided with a first row of through holes and a second row of through holes. The cover has a row of light-guiding rods at a back side thereof, which are respectively selectively insertable into the first or second row of through holes. The electronic device includes a circuit board and a plurality of lamps electrically connected to and controlled by the circuit board.
