Abstract:
A support for an electronic device includes a mounting apparatus and a supporting apparatus. The mounting apparatus includes a fixing bracket mounted to the main body of an electronic device, an engaging member slidably mounted to the fixing bracket, and a resilient member connected between the fixing bracket and the engaging member. The supporting apparatus includes a connecting bracket detachably mounted to the fixing bracket. When the engaging member is slid relative to the fixing bracket, a stop piece moves away from the connecting hole, and a hook extends through the connecting hole. After the engaging member is released the stop piece moves to the connecting hole to engage with the hook.
Abstract:
A drive circuit for light emitting diode (LED) is provided, which is used to drive a plurality of LEDs to emit light. The LEDs are connected in series into a plurality of LED strings. The drive circuit includes a power converter, a detection circuit, and a report circuit. The power converter provides a driving voltage to the LED strings, and the detection circuit detects a string voltage of each LED string, and compares the string voltage with a default reference voltage, so as to determine whether the string voltage is different from the reference voltage (which indicates that the LED string is operated under a non-default state), and sends a detection signal to the report circuit. The report circuit receives the detection signal and outputs the control signal to the power converter, such that the power converter adjusts the driving voltage according to the control signal.
Abstract:
A modular jack (100) includes an insulative housing (2) and a terminal-receiving part (3) having a pair of terminals (4) therein received in the housing (2). The terminal-receiving part (3) includes a pair of through apertures (341) accommodating the terminals (4), a leading-wire notch (325) positioned behind the apertures (341) and a leading-wire space (324) communicating with the leading-wire notch (325). A hole (211) is defined in a corresponding side wall (21) of the housing (2). A pair of wires (344) connecting to leading-wire end (41) of the terminals (4) extends through the leading-wire notch (325) and leading-wire space (324) out of the hole (211) of the side wall (21) of the housing (2).
Abstract:
A memory card connector has an insulative frame receiving conductive terminals therein, a slide guiding mechanism assembled on the insulative frame, and a shell. The slide guiding mechanism includes a sliding bar, a guiding bar, and a resilient element. The sliding bar defines a guiding groove. A link portion is formed on an end of the sliding bar. A driving member is arranged at an end of the sliding bar and opposite the link portion, and has a pushing portion and a drawing portion. A driven member has a pushed portion and a drawn portion. The driven member cooperates with a stop member to control stopping of a member card. The slide guiding mechanism further includes a first conductor and a second conductor respectively communicating with ends of a detecting circuit of a circuit system for detecting ejection of the memory card at the earliest time.
Abstract:
A memory card connector includes an insulative frame, a plurality of conductive terminals, an ejecting mechanism for guiding a memory card in or out, and a conductor connecting with a circuit system. The ejecting mechanism includes a guiding groove, a guiding device displacing in the guiding groove, and an urging element providing returning force for the guiding device. The conductor is located in a position before an ejection portion of the guiding groove for detecting the memory card as which is disconnected from a circuit system at the earliest time that the ejecting mechanism be ejected from a starting position of the ejection portion, thereby the circuit system has sufficient time to protect the proceeded data before the memory card disengages wholly from the terminals during the memory card ejects out, avoiding the proceeded data being lost and preventing the memory card from being damaged.
Abstract:
An electronic device includes a main body, a mounting device, and a supporting device. The mounting device attaches to the main body, and includes a mounting member, a bracket, and a latch. The bracket is mounted to the mounting member; the latch includes a securing section, and is slidably mounted to the bracket. The supporting device includes a retaining tab to engage the securing section. The supporting device is to be removed from the mounting device when the latch slides on the bracket to detach the securing section from the retaining tab.
