Abstract: A power supply device (10) includes a base (20) and a plug (30). The base includes a square recess (24) and a locating portion (242) positioned in the recess. The plug is removably received in the recess. The plug includes a square main body (32) and a groove (36). The locating portion is received in the groove. The main body can be positioned in the square recess in different orientations.

Abstract: A transparent key (100) of an electronic device includes a patterned portion (10) and a peripheral portion (11) surrounding the patterned portion. The patterned portion and the peripheral portion co-form a pressing portion (12), or one of the patterned portion and the peripheral portion forms the pressing portion. One of the patterned portion and the peripheral portion is made of silica gel, and the other one is made of plastic. The transparent key of an electronic device further includes a driving block protruded from the patterned portion or the peripheral portion, for electrically connecting the key and a printed circuit board (PCB). The transparent key of an electronic device made of silica gel has good feeling and long using life.

Abstract: An electronic apparatus includes a circuit board (10), a connector (20) disposed on the circuit board, an electronic component (30) electrically connected to the connector, and a retaining member (40). The circuit board defines a hole (12). The retaining member includes a positioning portion (44), and a pressing portion (42) connecting with the positioning portion. The pressing portion includes a pair of resilient pressing arms (426) pressing against the electronic component and holding it in position. The positioning portion comprises a locating post (444) engagingly received in the hole of the circuit board. The locating post includes a resilient hook (446). The hook is retractable, so that the locating post can be easily passed through the hole of the circuit board. Thus, the retaining member can be easily attached to or removed from the assembly.

Abstract: A key assembly (B) mounted on a circuit board (200) includes a frame (23), a keytop (24), a switch (21), and a light emitting component (22). The frame includes a protrusion (230) formed a front thereof. The keytop defines a slot (241) shaped to correspond to a shape of the protrusion. The protrusion is received in the slot without protruding from a surface of the keytop. The switch is for electrically connection to the circuit board. The light emitting component is disposed inside the frame and for electrically connection to the circuit board. An electronic device (A) utilizing the key assembly is also provided.

Abstract: An EMI shield apparatus includes an EMI shield (10) and a heat sink (20). The EMI shield comprises a pair of first sidewalls (14), a pair of second sidewalls (16), and an interconnecting top wall (12). The top wall and the first and second sidewalls cooperatively surround a receiving space (18). An electronic component (64) is received in the receiving space to be shielded. The heat sink is mounted between the top wall and the electronic component. A pair of receiving grooves (22) is defined in opposite sides of the heat sink. At least one projection (142) is stamped into an inner face of each of the first sidewalls, the projections received in the corresponding receiving groove. The EMI shield apparatus can not only protect the electronic component from EMI, but also can effectively dissipate heat generated by the electronic component.

Abstract: A communication device includes a housing (20) and an antenna (10). The housing comprises a retaining portion (22). The retaining portion defines a hole (24) surrounded by an inner wall (21). The inner wall includes a plurality of rib portions (28) parallel to a center axis (220) of the hole. A length of each of the rib portions is shorter than an overall length of the inner wall. Ends of the rib portions cooperatively form a step (27), and a pair of stop walls (29) is formed at opposite ends of the step respectively. The rib portions define a plurality of slots (26) therebetween. The antenna is rotatably attached to the retaining portion. The antenna includes a protrusion (166), and a width of each of the slot is slightly smaller than that of the protrusion. The stop wall and the protrusion cooperatively prevent the antenna from rotating excessively.

Abstract: A power supply device (10) includes a base (20) and a plug (30). The base includes a top wall (22), and a recessed portion (24) defined in the top wall. The plug is accommodated in the recessed portion, and is rotatable to different angles relative to the base according to corresponding requirements.

Abstract: An antenna assembly includes an electrical device (20) and an antenna coating (10). The electrical device includes a circuit board(22), an insulative cover (11) and a connection portion (24) pivotally interconnecting the circuit board and the insulative cover. The antenna coating is formed on the insulative cover and substantially covers the connection portion, thereby establishing electrical connection with the circuit board via the connection portion. By pivotally rotating the insulative cover on the electrical device, the antenna performance can be improved. Because the antenna coating is directly formed on the insulative cover of the electrical device, the antenna assembly has a simple structure.
