Abstract: A surface contact card holder includes a housing and a tray assembly. The housing includes a receiving frame and defining a receiving hole. The tray assembly includes a tray and a cover. The tray is slidable and receivable in the receiving frame from the receiving hole, the tray is configured for carrying a surface contact card therein. The cover is pivotally attached to the tray and covering the receiving hole. The cover includes a first end and a second end. When the first end of the cover is pressed to pivot the cover, the second end of the cover moves out of the receiving hole, the tray is slid out of the receiving frame to allow insertion and removal of the surface contact card from the housing.

Abstract: A chip card holder includes a housing, a receiving frame, a tray, and a pin. The housing defines a latching groove. The receiving frame is mounted to the housing, and the receiving frame includes at least one ejecting arm. The tray is slidably received in the receiving frame and defines a receiving groove configured for receiving a chip card. The tray includes a latching tongue. When the tray is received in the receiving frame, the latching tongue is latched in the latching groove, and the ejecting arm abuts against one end of the tray. The pin deforms the latching tongue to unlock the tray from the housing.

Abstract: A securing structure includes a housing, and a securing member. The housing defines a receiving space and includes a base at end of the housing adjacent to the receiving space. The base includes at least one latching patch secured on the base. The securing member includes a latching portion and at least one resisting portion extended from one side of the latching portion. The latching portion detachably engages with the at least one latching patch with an end of the at least one latching patch pressing the resisting portion toward the receiving space.

Abstract: A portable electronic device includes a housing defining an opening and a chip card ejecting mechanism. The chip card ejecting mechanism includes a pin slidably retained to the cover, a hinged carrier retained to the housing, and a spring. The hinge carrier includes a biasing plate resisting the cover, and the hinge includes a latching block and a resisting block. The latching block is latched with the hook to hold the cover in the opening. Depressing the pin against spring pressure exposes the chip card for easy removal.

Abstract: A key assembly is assembled to an electronic device. The electronic device includes a housing. The key assembly includes a number of keys and an elastic bracket. The keys are received in the housing. The elastic bracket includes a main plate and a plurality of pairs of pressing fingers extending from the main plate. Each pair of the pressing fingers press one of the keys for mounting the keys between the housing and the elastic bracket.

Abstract: A key assembly includes a key element and an engaging element. The key element has a main body including a number of elastic portions and a number of notches. The notches are defined at one side of the main body. The engaging element includes a number of latch portions protruding from one side of the engaging element. The latch portions mate in the notches. When the key element is operated, the elastic portions deformedly allow the latch portions to move out of or moving in the notches.
