Abstract: A holder for a surface contact card includes a main body, a pivotal shaft, and a cover. The main body has a latching block and defines a receiving groove configured for receiving a surface contact card. The cover includes a hinge portion and a latching tab. The pivotal shaft extends through the hinge portion and rotatably connects to the main body. The cover is pivotally and slidably engaged with the main body for covering the receiving groove, and the latching tab is latched with the block.

Abstract: A connecting structure includes a first metal plate, a second metal plate, a rivet, and two sealing members. The first metal plate defines a through hole, and the second metal plate defines an engaging hole aligned with the through hole. The rivet includes a head portion, a rivet body, and a latching end integrally formed together. An annular slot is defined between the rivet body and the latching end. The rivet body and the latching end have a larger diameter than the through hole. The head portion and the rivet body are received in the engaging hole, and the latching end extrudes an inner wall of the through hole to form an annular latching projection received in the annular slot. The two sealing members seal the through hole and the engaging hole.

Abstract: A shielding structure includes a frame and a removable plate. The frame includes a peripheral wall, and the removable plate located in the opening may be fixed to the connecting board, the removable plate defining an access hole. A scored line is defined between the removable plate and the connecting board. The shielding structure further defines an arcuate gap between the removable plate and the connecting board and communicating with the scored line, and a mating hole, the arcuate gap is for increasing the shearing stresses on shielding structure the scored line when the removable plate must be removed.

Abstract: A shielding assembly includes a frame including a catch protruding near one end thereof; and a cover including a main body. The main body is punched to form an opening and a latching portion protruding from the main body and aligned with the opening; the latching portion latches with the catch, the latching portion shields the opening to improve the shielding affect of the shielding assembly.

Abstract: A key button structure for entering data in an electronic device comprises a first key element and a second key element. The second key element is retained to the first key element by a retaining mechanism. The second key element has a joint positioned at a side thereof opposite to the first key element and two actuators 226 located at an opposite side thereof facing the first key element. The joint pivotably couples the second key element to a housing 10 of the electronic device.
