Abstract: The present invention is to provide a high-power connector having a heat dissipation structure, which includes a cover, a plurality of resilient metal terminals and a plurality of auxiliary metal plates. The cover is made of an insulating material and defines a plurality of receiving spaces therein. The resilient metal terminals are fitted in the receiving spaces respectively. The front section of each resilient metal terminal has an arcuate shape, passes through a lateral side of the cover, and is exposed from the cover. The front section of each auxiliary metal plate is electrically connected to the corresponding resilient metal terminal, and the rear section of each auxiliary metal plate is electrically connected to a circuit board. Since the auxiliary metal plates have relatively low impedance capable of rapidly releasing the heat generated by the connector, the components of the connector are prevented from premature aging attributable to high temperature.

Abstract: A flexible circuit board connector with anti-disengagement movable cover collectively assembled and structured to include a lengthwise insulator, a U-shaped movable cover, a number of connecting terminals, and a pair of anti-disengagement panels. When the movable cover is pulled up, frontal sections of wing panels configured on left and right sides of the movable cover are subjected to confinement by blocking panels provided with functionality to fence therein, therewith preventing the wing panels of the movable cover from flexing or deformation, thereby preventing disengagement of the movable cover, and extending applicable life-span of the flexible circuit board connector, as well as enhancing an electrical connection of a flexible flat cable and the flexible circuit board connector therebetween.

Abstract: A flexible circuit board connector engaging structure capable of preventing a movable cover from disengaging with an insulation body includes inverted L-shaped ribs at front ends of flanks at the movable cover and for retaining movements of the movable cover. When the movable cover is moved to a located position, the inverted L-shaped ribs are retained by block panels of locating members, such that the movable cover cannot be further pulled outward. Meanwhile, front sections of the flanks at the movable cover are also tugged by the block panels of the locating members without being expanded outward, thereby preventing deformation and bending of the flanks at the movable cover as well as preventing the movable cover disengaging from the flexible circuit board connector. Thus, lifespan of the flexible circuit board connector is prolonged while also enhancing electric connection between a flexible flat cable (FFC) and the flexible circuit board connector.

Abstract: An ultra-thin flat flexible circuit board connector includes a movable lid capable of lifting and overturning as an upper side wall of the flexible circuit board connector. Positions of the movable lid having been lifted and overturned are an at an opposite direction to that of the flexible circuit board to be inserted, and thus leaving insertion operations of the flexible circuit board entirely unaffected. A breadth of the lifting and overturning movable lid has a plurality of terminal grooves. When the movable lid is closed, terminals of the flexible circuit board are partially exposed in the terminal grooves at the movable lid, thereby effectively reducing thickness of the flexible circuit board connector for forming an ultra-thin flexible circuit board connector.
