Provided is an adjustable optical assembly (), including a bearing base (), a driving mechanism (), a zoom optical assembly (), and a compensating optical assembly (). The driving mechanism () includes: a bracket () having a bottom end connected to the bearing base () and a top end having a top groove () open upwards; guide rods () supported on the top groove (), the guide rods () coinciding with the direction of optical axes of the zoom optical assembly () and the compensating optical assembly (); a zoom bearer (); a compensating bearer (); a zoom driving assembly; and a compensating driving assembly. The zoom bearer () and the compensating bearer () are both mounted on the guide rods () and slidable along the guide rods (). Also provided are a corresponding periscopic optical zoom module and an assembly method therefor. According to the adjustable optical assembly (), the bracket () and the guide rods () are disposed on the bearing base (), thereby effectively ensuring that the moving directions of a zoom group and a compensating group do not deviate from a main optical axis. Moreover, the adjustable optical assembly () is compact in structure and convenient to assemble, and facilitates large-scale mass production.

Vibration absorption tubing and a manufacturing method thereof. The manufacturing method includes: a solder placement step including: placing solder at solder placement portions in an inner cavity of an adaptor; a pipe fitting step including: fitting a corrugated pipe and the adaptor respectively to adaptor matching portions at corresponding sides of the adaptor, to communicate an adaptor inner cavity with an inner cavity of the corrugated pipe and inner cavities of external connection tubing; and fixing or limiting positions of the corrugated pipe, the adaptor, and the external connection tubing to obtain a tubing assembly; and a component brazing step including: performing furnace brazing on the tubing assembly of the external connection tubing to obtain a main vibration absorption tubing. The vibration absorption tubing has favorable brazing consistency, enhancing connection reliability of components.

Vibration absorption tubing and manufacturing method thereof

An overcurrent protection circuit and a controller are provided. The overcurrent protection circuit includes a sampling circuit, a comparator circuit, a D flip-flop, and an output signal control circuit. The sampling circuit samples a current of a controlled circuit to obtain a sample signal. The comparator circuit compares the sample signal with a reference signal, and generates an overcurrent signal if the sample signal is greater than the reference signal. The D flip-flop generates a first level signal in response to the overcurrent signal. The output signal control circuit outputs, in response to the first level signal, a control signal for reducing the current of the controlled circuit. The controller includes a controlled circuit and the overcurrent protection circuit.
