A guide connector aims to connect two circuit boards to transmit signals between the two. The guide connector has a second guiding dock latching on one circuit board so that free ends of metal transmission lines of the guide connector may be securely inserted into insert holes of the circuit board. A first guiding dock is provided to connect other circuit board to enable other free ends of the metal transmission lines to be aligned with and inserted into insert holes of the other circuit board.

An improved package box comprising: a body having a first plate extended with a bendable fold from one side of the body, and a second plate extended with a bendable fold from the other side of the body opposed to the first plate. Flanges and corresponding indentations are formed at the interface between the first plate and the body, and between the second plate and the first plate. A plurality of containers is also formed between the second plate and the first plate, and between the second plate and the first plate by the combination of the two plates.

A storing lid to cover a signal transmission port of an electronic device includes a housing and a lid. The housing has an opening corresponding to the signal transmission port. The lid is movably located on the housing, and may be located on a first position when the signal transmission port is not in use to cover the opening and prevent dust or external objects from entering into the port. The lid is moved to a second position when the signal transmission port is in use so that the lid may be stored on one side of the opening without being lost.
摘要:
Methods and apparatus are disclosed for controlling switching regulators to automatically switch from a traditional pulse-width modulation (PWM) mode, when the load current is higher than a predetermined value, to a pulse-frequency modulation (PFM) mode, when the load current drops to a point lower than the predetermine value. Switching modes increases the efficiency of the regulator when the load current is low without provoking a large output voltage transient. In some embodiments, a single switching cycle regulates the output in the PFM mode, which reduces the switching losses and enhances the efficiency of the regulator.
