Abstract: A cable magnet ring of adjustable length and able to include anti-EMI magnets of different strengths includes a bracket and a number of pairs of magnetic blocks. The bracket includes a first connecting member and a second connecting member detachably mounted to the first connecting member. The magnetic blocks are detachably received in the first and second connecting members. The first connecting member is movable relative to the second connecting member, to adjust a length of the bracket. Through holes for receiving a cable are defined in the shape of each pair of magnetic blocks, in the first connecting member, and in the second connecting member.

Abstract: A shielding assembly is used to shield electronic element positioned on a motherboard of an electronic device. The shielding assembly includes a shielding frame fixed to a first surface of the motherboard, a heat dissipating module, and a shielding plate. The heat dissipating module is detachably assembled to the shielding frame. When the heat dissipating module is assembled to the shielding frame, the heat dissipating module and the shielding frame form a shielding space to receive the electronic element. The shielding plate is fixed to a second surface of the motherboard opposite to the shielding frame to completely shield the electronic element.

Abstract: A shield against electromagnetic radiation emanating from a server includes a shielding apparatus attached to a server chassis which contains a set of hard disk drive modules. Each hard disk drive module includes a bracket and a hard disk drive fixed therein. A gap is defined between one end of each bracket and the hard disk drive held in the bracket. The gaps of the brackets extend from top to bottom. The top plate of the chassis defines a slot corresponding to the gaps. The shielding apparatus includes a mounting plate and a set of spaced shielding units set vertically to the mounting plate. Each shielding unit defines a set of electrically-conductive vents functioning as waveguides to absorb electromagnetic radiation.

Abstract: A chassis for an electronic device includes a main housing and a removable cover. The main housing includes a base plate and two opposite side plates integrally formed together. The removable cover includes a main portion and two opposite side portions. The side portions are latched on the side plates. A space is defined between each side portion of the cover and each side plates of the main housing. A waveguide is formed between each side portion and each side plate to attenuate electromagnetic radiation in the space.

Abstract: An audio connector includes an audio plug and a jack. The audio connector includes an isolating housing and a terminal partially positioned in the housing. The jack forms a receiving portion for receiving the terminal. The terminal includes a metallic flange extending out of the housing. The housing forms an isolated covering portion on the main body surrounding the metallic flange.

Abstract: A computer includes a hard disc; a motherboard; a chassis, a group of cables and the partition. The cables include a first end, a second end and a flexible cable portion between the first end and the second end. The hard disc and the motherboard are assembled in the chassis. The partition includes a planar body defining a first hole and a second hole, the first hole and the second hole positioned at opposite ends of the planar body. The first end of the cables is connected to the hard disc, the flexible cable portion extends through the first hole of the partition, and reversely extends through the second hole of the partition, the second end of the cables is connected to the motherboard.

Abstract: Provided is a static discharge isolation device for mounting on a case of a computer. The case includes a sidewall with an array of exposed interfaces. The static discharge isolation device composed of a dielectric. The static discharge isolation device includes a main body. The main body defines a number of cavities. The number, size, shape, and arrangement of the cavities are such to ensure each interface of the computer being closely surrounded by a corresponding cavity.

Abstract: An audio interface used for mating with an earphone plug having an electronic conductor is disclosed. The audio interface comprises a socket body; and an insulation wrap protruding from the socket body, the insulation wrap defining a receptacle, the electronic conductor inserted in the receptacle and wholly wrapped by the insulation wrap.
