Abstract:
1. An electrical system, comprising: a module; an immovable element defining a cavity for receiving the module; an ejecting mechanism assembled between the immovable element and the module, and comprising a guiding frame, a groove frame and a first spring element for urging the module to withdraw out of the immovable element; the guiding frame of the ejecting mechanism comprising a swing element being rotatable around a pivot pin thereof and defining a guiding pin and a balance line, and a second spring element attached to the swing element for driving the swing element to come back when the element offsets from the balance line; the groove frame of the ejecting mechanism defining a continuous groove for guiding the guiding pin, the groove comprising thereof an entry located on the balance line, a first drive section extending from the entry and away from the balance line, a first return section extending from the first drive section toward the balance line, a second drive section extending from the first return section toward the balance line and a second return section extending from the second drive section, the groove defining a latching section between the first return section and the second drive section for locking the guiding pin, whereby the second spring element prevents the guiding pin from moving along a direction opposite to a predetermined direction.
