Abstract:
A wireless communication device with an antenna structure includes a wireless communication device body and an antenna. The antenna includes a first flexible laminate substrate, a second flexible laminate substrate, and an antenna metal layer. The antenna is disposed on a surface of a case of the wireless communication device body through the second flexible laminate substrate. The antenna metal layer is disposed between and is in contact with the first flexible laminate substrate and the second flexible laminate substrate. With the antenna disposed on the surface of the case of the wireless communication device, it is feasible to reduce the space required to accommodate an internal circuit of the wireless communication device, enhance the efficiency of the antenna for transmitting and receiving signals, and display any pattern on the outer surface of the antenna.
Abstract:
A HomePlug includes a body, a power socket, and a network port. The body has an installation region, an insertion region, and an operation region defined on a side surface of the body. The power socket is disposed on the insertion region and has a central point. The network port is disposed on the operation region and spaced apart from the central point by a specific distance. Accordingly, not only is the HomePlug convenient to manipulate, but a network cable connected to the HomePlug is also unlikely to bend, even though the HomePlug is installed at an electric outlet positioned proximate to the ground.
Abstract:
A HomePlug having a panel replacement structure includes a HomePlug body and a panel. The HomePlug body has an operation side and a network port. The operation side has an insertion portion and a first coupling portion. The panel has an opening and second coupling portion. The second coupling portion can be coupled to the first coupling portion so as to allow the opening to correspond in position to the insertion portion. Changes in the appearance of the HomePlug are brought about by panel replacement. A heat dissipation vent is disposed at the junction of the operation side and an adjacent side, such that heat dissipation takes place at the adjacent side-neighboring portion of the heat dissipation vent when the panel is coupled to the operation side and covers the operation side.
Abstract:
An electromagnetic shielding cover and a device having the same are introduced. The device comprises a casing and is coupled to a base having a printed circuit board on which an electronic component is mounted. The casing is defined with a receiving region. The electromagnetic shielding cover is disposed within the receiving region and coupled thereto. The electromagnetic shielding cover is marked with a plurality of peripheral folding lines. The electromagnetic shielding cover is folded along the peripheral folding lines by an angle to form a plurality of walls and a shielding space. Coupling the casing and the base together allows the electromagnetic shielding cover to shield an electronic component mounted on the circuit board and received in the shielding space, thereby shielding the electronic component from electromagnetic interference. The electronic component can be easily changed and tested during a rework process.
Abstract:
An assembled electromagnetic shielding case conducive to electromagnetic interference shielding and heat dissipation of an electronic component on a printed circuit board includes a body, a shielding element, and a fixing element. The body has an opening and an engagement portion. The engagement portion connects the body and the printed circuit board. The shielding element has a bottom side and a heat-dissipating side opposing thereto. The shielding element closes the opening for effectuating electromagnetic interference shielding. The shielding element dissipates heat generated from the electronic component by transferring the heat from the bottom side to the heat-dissipating side for dissipating the heat. The fixing element couples the body and the shielding element. Accordingly, with the assembled electromagnetic shielding case, not only is the electronic component insusceptible to electromagnetic interference and easy to change, but it is feasible to provide highly efficient heat dissipation and a miniaturized heat dissipation structure.
Abstract:
A power supply device using electric power network connects to an external power source and an electronic device, and supplies an alternating current power from the external power source to the electronic device to be a direct current power for the electronic device. In this case, the power supply device using electric power network comprises an electric power connection unit connected with the external power source, a conversion unit connected with the electric power connection unit, and an output unit connected with the conversion unit and the electronic device. The electric power connection unit is used for acquiring the alternating current power from the external power source, and the alternating current power is converted into a direct current power by the conversion unit. Thereby, the direct current power required for the electronic device during the process of charging and supplying power is supplied.
Abstract:
An electromagnetic shielding case and an electronic device having the same are introduced. The electronic device includes a PCB, which has at least one electronic component mounted thereon and is provided around the electronic component with multiple positioning holes. The electromagnetic shielding case includes a casing body internally defining a shielding space and multiple fixing pins formed on lower edges of the casing body corresponding to the positioning holes on the PCB. Each fixing pin includes a neck portion and an end portion with an angle included therebetween. After the fixing pins are correspondingly extended through the positioning holes, the end portions can be deflected by an angle to thereby hold the casing body to the PCB with the electronic component located in the shielding space and shielded against EMI. With these arrangements, the electromagnetic shielding case can be quickly mounted to and dismounted from the PCB.

An electromagnetic shielding cover disposed on a printed circuit board having thereon an electronic component includes a lid and a frame which are coupled together to shield the electronic component from electromagnetic interference and allow the electronic component to be changed and tested easily during a rework process.
Abstract:
A flat panel display with detachable anti-vibrate speaker includes a speaker body with a front bezel attached at least one speaker driver, a rear bezel and a middle frame. The middle frame with a bottom positioning hole is made of an elastic material and situated between the front bezel and the rear bezel, and an elastic rib is formed on an inner surface of the middle frame to separate and to be against the front bezel and the rear bezel. A stand includes a positioning structure and a top surface groove. The positioning structure is assembled inside the top surface groove and is blocked by a blocking member fixed on an upper surface of the top surface groove. An elastic member is situated in the bottom of the top surface groove and a positioning member with a round top is located between the blocking member and the elastic member and is pushed to fit the positioning hole by the elastic member.
