This utility model discloses a radio frequency transceiver for communication, relating to the field of electrical communication technology. It includes: a housing with an antenna connected to one end; a circuit board installed inside the housing and electrically connected to the antenna; a signal transmitting module and a signal receiving module, respectively integrated on the circuit board; and a pair of shielding covers installed on the circuit board, respectively covering the signal transmitting module and the signal receiving module. By providing a bushing on the inner surface of a first ferrite semi-magnetic ring, and making the portion of the bushing inside the first ferrite semi-magnetic ring form a load-bearing structure, when the wire harness is placed on the bushing, the bushing provides an upward load-bearing force to the wire harness. This load-bearing force can balance the downward tendency of the wire harness under gravity, thereby effectively preventing the wire harness from rubbing against the hole wall of the shielding cover due to long-term downward movement and preventing excessive gaps between the top of the wire harness and the inner wall of the second ferrite semi-magnetic ring. This prevents wear of the wire harness insulation layer or breakage of the wire core and magnetic leakage caused by increased gaps above.

This invention relates to the field of molding and joining equipment for plastic sheets, specifically to a far-infrared hot-melt overlapping plastic box forming device, comprising a frame, a lower pressure mold fixedly connected to the frame, and a pressing mechanism.
