The coupling frame is sandwiched between the receptacle of the power supply input socket and the power supply, and has an opening to receive the body of the power supply input socket and anchor flanges extended from two sides that have respectively an anchor bore to couple with the power cord latch clip thereby to overcome the problems occurred to the conventional power cord coupling fixtures used on the inserting power supply input sockets.
Abstract:
An arc discharge protection apparatus to prevent arc discharge from occurring in a high voltage output zone caused by abnormal conditions includes an electrode plate to absorb high voltage arc discharge signals released by a voltage boosting unit in the high voltage output zone. A voltage switch unit receives the high voltage arc discharge signals absorbed by the electrode plate and transforms to low voltage arc discharge signals. A rectification unit receives and rectifies the low voltage arc discharge signals and outputs an arc hybrid wave. A trigger unit detects the arc hybrid wave and outputs a trigger signal to stop operation of the control unit or driving unit, thereby prevents arc discharge from causing damage to the surrounding elements resulting from accumulation of heat or sparks.

A waterproof piezoelectric ceramic speaker includes a ceramic composite and a vibration membrane. The ceramic composite includes a ceramic plate and a driving electrode assembly arranged on the ceramic plate and supplying a driving voltage to the ceramic plate to generate vibration for the ceramic plate. The vibration membrane includes a first vibration layer and a second vibration layer respectively adhered to two opposite surfaces of the ceramic composite. The first vibration layer and the second vibration layer respectively have a resonance member adhered to the ceramic plate and resonating with the ceramic plate synchronously, a waterproof member connecting with the resonance member to seal the driving electrode assembly, and a bonding member extending from a perimeter of the resonance member to seal the resonance member.
Abstract:
A headphone wireless expansion device for switching among multiple targets is connected to an information device to receive audio data which is then transmitted to a headphone for playing. The headphone wireless expansion device includes multi-target connection data and an audio control mechanism. The multi-target connection data includes a plurality of device identification codes, a plurality of device authorization codes corresponding to a plurality of information devices respectively, and a plurality of audio tags corresponding to the device identification codes and the device authorization codes respectively. The audio control mechanism searches the audio tag having audio features same as that of the unrecognized audio signal, and reads the corresponding device identification code and device authorization code. The headphone wireless expansion device enables a conventional wired headphone to wirelessly connect with the information device and switch among multiple information devices via a voice control method through identifying the audio tag.

Abstract:
An illuminated keyboard is equipped with a thin key module which includes a support frame with multiple keycap installation apertures and multiple keycaps corresponding to the keycap installation apertures. Each keycap has at least three movable arms each is connected between the first wall of one side of the keycap and the second wall of the keycap installation aperture. The support frame, keycaps and movable arms are integrally formed by injection. The movable arm has a first connecting section connected to the keycap and a second connecting section connected to the first connecting section at a first bend spot. The second connecting section is extended between the keycap and support frame and connected to the keycap installation aperture. In the illuminated keyboard, light is generated by a lighting unit and transmitted through a light guide plate or light guide circuit board to project to the keycaps for illumination.
Abstract:
A micro-switch provided labor-saving switching comprises a housing, a press member located on the housing, an actuation member located in the housing and a driving assembly located between the press member and actuation member. The press member is depressed to move reciprocally in the housing in a displacement.
