Abstract: A circuit board fixing structure (100) includes a base (3) and a circuit board (2). The base has a plurality of elastic claws (32) and the elastic claws vertically extend from the base. Each elastic claw includes a fastening portion (34), which forms a fastening surface (36) facing to a top surface of the base. The circuit board is encircled by the elastic claws and an upper surface of the circuit board confronts the fastening surface of the fastening portion.

Abstract: An electrical connector (100) includes a base (3), which is shaped in a basin and comprises at least one elastic assembly (35). A first connector module (5) and a second connector module (6) are both assembled on the base and they are electrically connected to each other. Each connector module communicates with an outside complementary connector. The electrical connector comprises an inner cover (2) which is attached to the base and the inner cover defines a plurality of fixing slots (21). The electrical connector further comprises a top cover (1) which forms a plurality of fixing members (17, 17?) thereof and the fixing members correspond to the fixing slots of the inner cover. The fixing members are engaged with or separated from the fixing slots by a rotation of the inner cover along a clockwise or counterclockwise direction by virtue of the elastic assembly.

Abstract: A remote control device (100) includes an insulated housing (2, 3) including an outer surface (20, 30) plated with a conductive material for providing a suppression of EMI, an inner surface (21, 31), and a receiving space (4) defined by the outer surface and the inner surface, a printed circuit board (51) received in the receiving space, and including at least a first conductive pad (511), and a second conductive pad electrically connected to the first conductive pad by conductive trace, a cable including at least one grounding conductor electrically connected to the second conductive pad, grounding means (22) electrically connected to the conductive material and the first conductive pad for providing a sheath for ESD generated on the remote control device.

Abstract: A multi-directional switch includes a switch module, including a generally rectangular base, and an actuator vertically installed into a central receiving chamber defined in the base, the actuator can tilt away from a vertical axis to close one of four corners of the base, and a manual handle mated with the switch module, defining a central hollow being open toward the actuator for fittingly receiving the actuator therein, so as to permit synchronously swinging movement of the manual handle and the actuator. For preventing the manual handle, together with the actuator, synchronously swinging toward one of four corners, after the actuator is fittingly received in the central hollow of the manual handle, at least a rib is formed at a top surface of the base for abutting against a bottom surface of the manual handle, or formed at a bottom surface of the manual handle for abutting against a top surface of the base.

Abstract: A charger assembly for a portable device includes a charger module for converting an outside source into a predetermined source for the portable device, a loudspeaker module comprising at least one filter for eliminating undesired signals form outside and inside of the charger assembly, an amplifier for amplifying the voice signals from said portable device to drive a speaker. The filter is a low-pass filter for eliminating the high frequency noise signals from the charger module.
