Function element 101 on plate 40, the helical 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 passes through several lug boss E1 of the second spring card K2
It is electrically connected with the electric connection area 21 of the housing 20.
In one embodiment, the function element 101 is antenna modules 10, and the helical spring T1 passes through described first
Spring card K1 is electrically connected after being fixed on pcb board 40 with the antenna modules 10 being installed on pcb board 40, and described second
Spring card K2 is electrically connected with the electric connection area 21 of the housing 20, is connected so as to establish antenna modules 10 with the electrical of housing 20
The electrical connection in area 21 is connect, and the housing 20 is electrically connected radiator of the area 21 as antenna modules 10.Wherein, the shell
The electric connection area 21 of body 20 can be the subregion of entire housing 20 or housing 20.The electric connection area 21 is housing
During 20 subregion, the centre position of housing 20, two side positions can be located at, shape can be square, circular, triangle etc..
Wherein, the pcb board 40 can be an antenna circuit board that is used only for installing and carry antenna modules 10.It is described
The mainboard of pcb board 40 or a terminal device, in addition to being equipped with the antenna modules 10, is also equipped with other Functional Units
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, other functions after the spring T1 is fixed on pcb board 40 with being installed on pcb board 40
Element is electrically connected and is electrically connected with the electric connection area 21 of housing 20.For example, with the power circuit that is installed on pcb board 40 etc.
Ground connect, and using the electric connection area 21 of housing 20 as publicly or the memory with being installed on pcb board 40, handle
The connections such as device, display chip, using the electric connection area 21 of housing 20 as Electro-static Driven Comb.It is below day with function element 101
It is illustrated exemplified by line module 10.
Specifically, in one embodiment, the helical 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
Two spring card K2 are electrically connected with the inner surface in the electric connection area 21 of housing 20.In one embodiment, to pass through second spring
Card K2 contradicts the inner surface in the electric connection area 21 of housing 20 and is electrically connected.Wherein, the first end 31 and second end 32 are
Two ends of the helical spring T1.The helical spring T1 be spiral circle cylindrical spring, the helical spring T1
Spring ring diameter it is roughly equal from first end 31 to second end 32.Specifically, helical spring T1 is by multiple bullets extended spirally
Property spring coil composition, the first end 31 and second end 32 of helical spring T1 include horizontal segment and are inclined upwardly from horizontal segment to prolong
The tilting section stretched, and form the spring coil do not closed.
Wherein, the inner surface of the pcb board 40 and housing 20 is substantially parallel, and the telescopic direction of the helical spring T1 is big
It causes as along the orientation of first end 31 and second end 32, i.e., perpendicular to the direction of 20 inner surface of the pcb board 40 or housing.
So as to generate power when housing 20 is acted on be subject to external force compared with pcb board 40 and be acted on, due to helical spring T1
Scalable movement can also be distorted towards other directions different from telescopic direction so that housing 20 occurs slightly with respect to pcb board 40
When mobile, helical spring T1 with second spring card K2 can follow housing 20 together with move, and keep helical spring T1's
Second end 32 and second spring card K2 and the contact position of housing 20 are constant.Therefore, connection structure 30 and housing 20 are avoided
It rubs, loose contact caused by the abrasion of 20 inner surface of housing will not be caused.
Also referring to Fig. 3, decomposition and assembling schematic diagram for connection structure 30.The first spring card K1 includes bottom
Plate D1, the bottom plate D1 include opposite the first face F1 (as shown in Figure 1) and the second face F2.The first face F1 of the bottom plate D1
