Embodiment 1

[0029] see figure 2 , the decorative ring 130 includes a top end 131 and a bottom end 132 opposite to each other. The top end 131 is against the casing 140 . The bottom end 132 is against the antenna feeder 120 .

[0030] In this embodiment, the decorative ring 130 directly interferes with the antenna feeder 120 . The antenna feeder 120 may be disposed at a position facing the decoration ring 130 . When assembling the mobile terminal 300, the top end 131 of the decorative ring 130 is fixed to the housing 140, and the bottom end 132 of the decorative ring 130 is abutted against the antenna feeder 120 to realize the decorative ring 130. While electrically connecting the antenna feeder 120 , the decoration ring 130 is also supported between the casing 140 and the circuit board 110 , so as to increase the overall stability of the mobile terminal 300 .

[0031] For the first implementation, see Figure 4 , the antenna feeder 120 includes an antenna shrapnel 121 . The antenna...

Embodiment 2

[0047] see Figure 9 , the difference from the first embodiment is that the functional component 100 further includes a pressing plate 180 . The pressing plate 180 is fixedly connected to the casing 140 and resisted against the antenna feeder 120 . The decorative ring 130 is fixed on a side of the pressing plate 180 away from the circuit board 110 , and is held against the antenna feeder 120 by the pressing plate 180 . The pressing plate 180 includes a pressing plate body 181 and a pressing plate support 182 . The pressing plate body 181 is opposite to the circuit board 110 for supporting the decoration ring 130 and the cover plate 150 . The pressing plate bracket 182 is in contact between the pressing plate body 181 and the antenna feeder 120 . The pressing plate bracket 182 is arranged on the peripheral side of the camera module 160 and the flash module 170, so that the cover plate 150 covers the camera module 160 and the flash module 170 at the same time, forming an anti...

Embodiment 3

[0051] see Figure 10 , the housing 140 includes a connection end 144 against the antenna feeder 120 . The connection end 144 may be disposed on the inner surface 142 of the casing 140 , and the antenna feeder 120 abuts against the connection end 144 during the installation of the casing 140 . The decorative ring 130 is electrically connected to the connection end 144 to realize the electrical connection of the decorative ring 130 to the antenna feeder 120 .

[0052] In one implementation, see Figure 10 , the functional component 100 further includes a grounding shrapnel 190 . The ground spring 190 is fixed on the circuit board 110 and electrically connected to the decoration ring 130 .

[0053] In this embodiment of the present application, there is no limitation on the antenna form and the number of antenna interfaces in the antenna feeder 120 . For a monopole antenna, the antenna feeder 120 can be connected to the signal end of the radio frequency transmission line thr...

Abstract

The invention discloses a functional assembly and a mobile terminal. The functional assembly comprises a circuit board, an antenna feed part and a decorative ring fixed on the circuit board; the antenna feed part is used for transmitting and receiving an electromagnetic signal; and the decorative ring is electrically connected with the antenna feed part and the circuit board. By enabling the decorative ring to be electrically connected to the antenna feed part, the decorative ring can be used as a radiator of the antenna, so that the radiation area of the radiator of the antenna is enlarged, and interference of the decorative ring to electromagnetic signal radiation can be avoided; the decorative ring is arranged on the shell of the mobile terminal and exposed outside the mobile terminal,and the decorative ring is used as the radiator of the antenna feed part, so that interference from other components in the mobile terminal to the decorative ring can be reduced; the electromagnetic signal receiving and transmitting capabilities of the mobile terminal are reinforced without an additional structure, so that the communication capability of the mobile terminal can be further improved; and the functions and utilization rate of the decorative ring in the mobile terminal also can be improved.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to a functional component and a mobile terminal.
