20110039433 | PRODUCT STRUCTURE WITH EJECTOR - A product structure includes a base and an ejector including a core, a sliding sheet, a guiding rod and an elastic member. The core has a sliding slot, which has a circulating path, one end formed with a positioning point, the other end formed with a starting point, and a bottom surface formed with unidirectional stopper blocks, so that the path unidirectionally circulates from the starting point sequentially to the positioning point and to the starting point. The sliding sheet having a pushing portion may slide back and forth relatively to the base. The rod has one end engaged with the slot and can slide along the path. The elastic member provides an elastic force for returning the sliding sheet, after being moved into the base, to a home position. The core has a seat and a metal baseplate, which is engaged with the seat and has the stopper blocks. | 02-17-2011 |
20110045681 | ELECTRICAL CONNECTOR - An electrical connector includes a plastic base and an engaging member. The base has a longitudinally extended connection slot to be connected to a circuit board having one side formed with a notch. The engaging member disposed on one side of the base has an elastic arm, which has a handle, a guide-in inclined surface, an engaging portion and an elastic member. When the circuit board is inserted into the slot, the one side thereof presses the guide-in inclined surface to make the arm elastically move outwardly. When the arm elastically moves back, the engaging portion engages with the notch. When the handle is moved to make the arm elastically move outwardly and to disengage the engaging portion from the notch, the elastic member can stop the engaging member from elastically moving back to engage with the notch, so that the circuit board can be conveniently taken out. | 02-24-2011 |
20110086530 | MULTILAYER ELECTRONIC CARD CONNECTOR WITH EJECTOR - An electronic card connector includes a base, upper and lower terminals and an ejector including a core, a sliding sheet, a guiding rod and an elastic member. A baffle separates the base into upper and lower slots for respectively accommodating upper and lower cards. The core has a sliding slot, which has one end having a concave positioning point, and the other end having a starting point, such that unidirectional circulation successively from the starting point to the positioning point and then to the starting point is formed. The sheet may slide relatively to the base and has first and second pushing portions respectively disposed in the lower and upper slots. The rod has one end engaged into the sliding slot and is slidable along the sliding slot. The elastic member provides elasticity for moving the sliding sheet into the base and then returning the sheet to a home position. | 04-14-2011 |
20110244701 | ELECTRICAL CONNECTOR AND ONE PAIR OF SWITCH TERMINALS THEREOF - An electrical connector includes a base, terminals each being disposed on the base and having a contact, and one pair of switch terminals, disposed on the base, including first and second terminals each having a fixing portion, a pin portion and an extension.
