Referring to fig. 1 and fig. 2, in the housing 100 according to the present invention, the housing 100 has a near field communication area 10, and a metal coil 11 and a gap 12 separated by the metal coil 11 are disposed in the near field communication area 10. The metal coil 11 is used as a radiator, the metal coil 11 includes a first contact end 111 and a second contact end 112, the first contact end 111 and the second contact end 112 are used to be electrically connected to the nfc feeding module 20, and the slot 12 is filled with an insulating material. It is understood that the housing 100 is applied to a terminal, which may be a mobile phone, a tablet computer, a music player, etc. The metal coil 11 may radiate or induce an electromagnetic signal so as to transmit and receive a signal through the near field communication power feeding module 20.
By arranging the metal coil 11 in the near field communication area 10 of the housing 100, the metal coil 11 is used for receiving a feed signal of the near field communication feed module 20, so as to radiate the near field communication signal, so that the housing 100 can directly radiate the near field communication signal, the near field communication signal is prevented from being shielded, and user experience is improved.
In this embodiment, the housing 100 may be a terminal housing including a rear cover, a frame, and a front shell, and may also be a terminal front cover (including a display panel and/or a display module) or a terminal rear cover (including a frame and/or a rear cover). The housing 100 is made of metal. The housing 100 may carry an internal main board and other functional components of the terminal and protect the main board and the functional components. The slot 12 of the near field communication area 10 may be cut by a laser. Specifically, the near field communication area 10 and the gap 12 are planned on a metal plate according to a preset pattern, and are cut according to the preset pattern, and the metal coil 11 is cut and formed along with the gap 12, so that the gap 12 and the metal coil 11 are formed in the communication area 10 of the housing 100. Specifically, the metal coil 11 is in a spiral coil shape. The insulating material in the gap 12 may be filled using an injection process. The insulating material in the slot 12 provides an insulating environment for the metal coil 11 and secures the metal coil 11 in the near field communication area 10. The first contact end 111 and the second contact end 112 may be electrically connected to the nfc feeder module 20 by soldering. In other embodiments, the metal coil 11 may be formed by two parallel conductive wires, and the two parallel conductive wires are respectively electrically connected to two different nfc feed modules 20, so that the housing 100 implements two different nfc modes.

The near field communication area 10 surrounds the shooting hole 60, so that the use area of the housing 100 is fully utilized.
Further, the slit width of the slit 12 is smaller than the line width of the metal coil 11, so that the area of the slit 12 is smaller than the area of the metal coil 11. The insulating material filled in the gap 12 has a small stress and cannot bear a large pressure, and the stress of the metal coil 11 is larger than the stress of the insulating material and can bear a large pressure. Therefore, the area of the metal coil 11 is larger than that of the slot 12, so that the pressure resistance of the housing 100 in the near field communication area 10 is improved.
