2results about How to "Constant size" patented technology

This application relates to a dimmable power supply, which includes a communication module, a constant current control module, and a digital potentiometer. The digital potentiometer's signal processing changes the current setting of the maximum output current of the constant current control module. A PWM signal is output through the PWM interface of the communication module, allowing the constant current control module to set its current output current based on the duty cycle of the PWM signal. This not only allows for remote and flexible setting of the maximum output current even after potting, but also ensures that in the event of a communication module failure, the constant current control module outputs a high or low level, maintaining the current at the current setting of the maximum output current or zero, without damaging the power supply itself. Furthermore, the resistance of the digital potentiometer remains unchanged due to a communication module failure, thus ensuring a stable maximum output current and preventing damage to the load.

This utility model discloses a component disassembly fixture, relating to the field of electronic component disassembly and assembly technology, aiming to solve the problems of cumbersome operation, easy damage to PCBA, and environmental unfriendliness of existing disassembly methods. The fixture includes a base, a PCBA support mechanism for supporting the PCBA, and a disassembly mechanism; the disassembly mechanism includes an elastic reset component and a clamping component for holding the component to be disassembled. The core of this component disassembly fixture lies in the fact that when the clamping component holds the component to be disassembled, the elastic reset component applies a continuous pulling force to the component. Before the solder pads melt, this pulling force is used to press the PCBA back against the support mechanism for stable fixation; after the solder pads melt, it is used to automatically pull the component out. This utility model achieves two functions in one, with an ingenious structure, not only simplifying operation and improving disassembly efficiency and quality, but also possessing the advantages of energy saving and environmental protection.
