An apparatus comprises a transceiver (Tx/Rx) printed circuit board (PCB) with a top surface and a bottom surface and a power supply PCB. The Tx/Rx PCB includes two transmitter devices, each comprising a number N of channels. A first transmitter device is arranged on the bottom surface and a second transmitter device is arranged on the top surface over the first transmitter device. One or more pins of the second transmitter device are shorted with one or more pins of the first transmitter device with the same function. An analog front end (AFE) device comprising N input channels is arranged on the top surface of the Tx/Rx PCB, and a digital signal processor is coupled to the AFE device. The power supply PCB comprises a power supply module configured to provide a plurality of supply voltages to the Tx/Rx PCB and the power supply PCB.

A centrifugal impeller for a blower has a base plate, a cover plate, and a plurality of curved blades mounted between the base plate and the cover plate. The base plate and the cover plate have blade mounting portions including a plurality of mounting holes. Cover plate mounting portions and base plate mounting portions project from each blade and engage with the mounting holes of the cover plate and base plate, respectively. The mounting holes of the cover plate include first mounting holes arranged outwardly from a central region. The first mounting holes have a circular shape. The cover plate mounting portions of each blade include first mounting protrusions engaged with the first mounting holes.

Centrifugal impeller for a blower

A blower has a centrifugal impeller driven by an electric motor. The centrifugal impeller has a base plate, a cover plate defining an air inlet, a plurality of blades mounted between the base plate and the cover plate, and a reinforcement ring mounted to the cover plate around the air inlet. The cover plate includes an outwardly extending flange at the air inlet. The reinforcement ring has a flange fitted around the flange of the cover plate. Each blade has cover plate mounting portions and base plate mounting portions. The cover plate has blade mounting holes engaged with the cover plate mounting portions. The base plate has blade mounting holes engaged with the base plate mounting portions. The reinforcement ring increases the strength of the cover plate, to avoid breakage under high speed rotation.

Disclosed is a mobile terminal. The mobile terminal comprises an antenna body and a metal ring. The metal ring is provided on the mobile terminal without contacting the antenna body, and the vertical projection of the metal ring on a plane where the antenna body is located intersects the antenna body. By means of the disclosure, signal receiving performance of the mobile terminal is improved, and the loss caused by head and hand is reduced to a certain extent.

Mobile terminal

The present disclosure discloses an ultra-wideband antenna, including: a coplanar waveguide feeder connected to a Radio Frequency (RF) excitation port on the PCB substrate at one end and to a tapering supporting arm at the other end; the tapering supporting arm connected to the coplanar waveguide feeder at one end and to a primary radiating closed-band-shaped monopole at the other end; the primary radiating closed-band-shaped monopole connected to the tapering supporting arm; a primary coupling patch located in the area closed by the closed band of the primary radiating closed-band-shaped monopole; a secondary radiating closed-band-shaped monopole connected to the primary radiating closed-band-shaped monopole through a metallic via; and a secondary coupling patch located in the area closed by the closed band of the secondary radiating closed-band-shaped monopole. The present disclosure also discloses an ultra-wideband terminal. With the antenna and the terminal of the present disclosure, space usage is reduced, facilitating development of an ultrathin terminal and widening bandwidth, and thus allowing the terminal to operate in the range of an ultrawide band.

Ultra-wideband antenna and terminal

The panel unit includes a plurality of holding members corresponding to the retaining members and a plurality of assembling members corresponding to the fastening member. The retaining members and the holding members are correspondingly assembled together to assemble the first frame unit to the panel unit, and the fastening members and the assembling members are correspondingly assembled together to assemble the second frame unit to the panel unit.

Housing of portable electronic device

A holder for a surface contact card includes a first housing, a second housing, and a tray. The first housing defines a receiving hole. The second housing includes a cover portion. A tray is configured for carrying a surface contact card therein. The cover portion covers one part of the tray. The tray slidably engages in the receiving hole allowing insertion and removal of the surface contact card from inside the first housing and the second housing.

Surface contact card holder for electronic device

A chip card holder is configured for receiving a chip card. The chip card holder includes a housing defining a groove, a latching part received in the groove, a fixing element made of rubber material. The chip card is received in the latching part. The fixing element includes a main plate, a positioning portion, a rib, and a free end. The positioning portion is positioned on a side of the main plate. The positioning portion latches the housing. The rib is positioned on the same side which positioning the positioning portion. The rib resists the chip card. The free end extends from a peripheral edge of the main plate. The present disclosure further discloses an electronic device using the chip card holder.

Chip card holder and electronic device using the same

A housing assembly for a portable electronic device includes a shell including a supporting portion, a frame, and a latching member. The latching member includes a body portion, at least one positioning portion and at least one bent portion. The body portion is disposed on the shell. The positioning portion is secured in the shell. The bent portion engages the frame. The supporting portion of the shell resists the positioning portion of the latching member.
