It is the schematic diagram of the casing device 100 in the first embodiment of the present invention please with reference to Fig. 1 and Fig. 2, Fig. 1.Institute
Stating casing device 100 includes shell 20 and connection structure 30.The connection structure 30 includes Pear-Shaped spring T1, the first spring
Card K1 and second spring card K2, the Pear-Shaped spring T1 are fixed on PCB by the first spring card K1
On (Printed circuit board, printed circuit board) plate 40, the Pear-Shaped spring T1 simultaneously passes through the second spring card
Piece K2 is electrically connected with the shell 20.Wherein, the spring ring diameter of the Pear-Shaped spring T1 gradually subtracts from one end to predetermined position
It is small, and be gradually increased from the predetermined position to the other end.
The shell 20 includes electric connection area 21 as shown in Figure 2.The casing device 100 further includes being installed on PCB
Function element 101 on plate 40, the Pear-Shaped spring 30 by the first spring card K1 be fixed on pcb board 40 after with
The function element 101 being installed on pcb board 40 is electrically connected, and is electrically connected with the electric connection area 21 of the shell 20.
In one embodiment, the function element 101 is antenna modules 10, the Pear-Shaped spring 30 and the shell 20
Electric connection area 21 and the antenna modules 10 that are installed on the pcb board 40 be electrically connected, by the electricity of the shell 20
Radiator of the property bonding pad 21 as antenna modules 10.Wherein, the electric connection area 21 of the shell 20 can be entire shell 20
It can also be the partial region of shell 20.When the partial region for being electrically connected area 21 as shell 20, it can be located in shell 20
Between position, two side positions, shape can be rectangular, round, triangle etc..
Wherein, the pcb board 40 can be used only for installing and carrying the antenna circuit board of antenna modules 10 for one.It is described
Pcb board 40 can also be also equipped with other Functional Units other than being equipped with the antenna modules 10 for the mainboard of a terminal device
Part, such as processor, memory etc..In some embodiments, the pcb board 40 can also be one of the antenna modules 10
Point.In further embodiments, the spring T1 is fixed on other functions that are rear on pcb board 40 and being installed on pcb board 40
Element is electrically connected and is electrically connected with the electric connection area 21 of shell 20.For example, with the power circuit that is installed on pcb board 40 etc.
Ground connection, and by the electric connection area 21 of shell 20 as publicly, or be installed on pcb board 40 memory, processing
The connection such as device, display chip, as Electro-static Driven Comb by the electric connection area 21 of shell 20.It is below day with function element 101
It is illustrated for line mould group 10.
Specifically, in one embodiment, the Pear-Shaped spring T1 includes first end 31 and second end 32, the first end
31 are fixed on the pcb board 40 by the first spring card K1 and are electrically connected with antenna modules 10, and the second end 32 passes through the
Two spring card K2 are electrically connected with the inner surface in the electric connection area 21 of shell 20.In one embodiment, to pass through second spring
