Specific embodiment

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment for being obtained, belongs to the scope of this utility model protection.

Please with reference to the signal that Fig. 1 and Fig. 2, Fig. 1 are the casing device 100 in first embodiment of the present utility model Figure.The casing device 100 includes housing 20 and attachment structure 30.The attachment structure 30 include helical spring T1, the One spring card K1 and second spring card K2, the second spring card has some lobe E1.The helical spring T1 is fixed on a PCB (Printed circuit board, printed circuit board (PCB)) plate 40 by the first spring card K1, The helical spring T1 is fixedly connected with the second spring card K2, and by some lobe of second spring card K2 E1 is electrically connected with the housing 201.Wherein, the spring ring diameter of the helical spring T1 passes through equal.

The housing 20 includes electric connection area 21 as shown in Figure 2, and the casing device 100 also includes being installed on PCB 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 by some lobe E1 of the second spring card K2 Electrically connect 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, so as to set up electrically connecting for antenna modules 10 and housing 20 The electrical connection in area 21 is connect, and the housing 20 is electrically connected with into area 21 as the radiant body of antenna modules 10.Wherein, the shell The area 21 that is electrically connected with of body 20 can be the subregion of the alternatively housing 20 of whole housing 20.The electric connection area 21 is housing During 20 subregion, the centre position of housing 20 is can be located at, two side positions, shape can be square, circular, 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 is alternatively the mainboard of a terminal unit, in addition to being provided with the antenna modules 10, is also equipped with other Functional Units Part, such as processor, memorizer etc..In certain embodiments, the pcb board 40 can also be of the antenna modules 10 Point.In further embodiments, with the other functions being installed on pcb board 40 after the spring T1 is fixed on pcb board 40 Element is electrically connected and electrically connected with the electric connection area 21 of housing 20.For example, with the power circuit being installed on pcb board 40 etc. Ground connection, and using the electric connection area 21 of housing 20 as publicly, or with the memorizer being installed on pcb board 40, process Device, display chip etc. connect, using the electric connection area 21 of housing 20 as Electro-static Driven Comb ground.Below with function element 101 as day Illustrate as a example by line module 10.

Specifically, in one embodiment, the helical spring T1 includes the end 32 of first end 31 and second, the first end 31 are fixed on the pcb board 40 and electrically connect with antenna modules 10 by the first spring card K1, and second end 32 is by the Two spring card K2 are electrically connected with the inner surface in the electric connection area 21 of housing 20.In one embodiment, it is by second spring Card K2 contradicts the inner surface in the electric connection area 21 of housing 20 and electrically connects.Wherein, the end 32 of the first end 31 and second is 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 the end of first end 31 to the second 32.Specifically, helical spring T1 by multiple spiral extensions bullet Property spring coil composition, the end 32 of first end 31 and second of helical spring T1 includes horizontal segment and is inclined upwardly from horizontal segment to prolong The tilting section stretched, and form the spring coil do not closed.

Wherein, the pcb board 40 is almost parallel with the inner surface of housing 20, and the telescopic direction of the helical spring T1 is big Cause is the orientation along the end 32 of first end 31 and second, i.e., perpendicular to the pcb board 40 or the direction of the inner surface of housing 20.

So as to producing power relative to pcb board 40 and be acted on when housing 20 is acted on by external force, due to helical spring T1 Scalable motion, it is also possible to towards other direction distortions different from telescopic direction so that the relative pcb board 40 of housing 20 occurs slightly When mobile, helical spring T1 can follow housing 20 with second spring card K2 together with move, and keep helical spring T1's Second end 32 and second spring card K2 are constant with the contact position of housing 20.Therefore, it is to avoid attachment structure 30 and housing 20 Rub, be not result in the loose contact that the abrasion of the inner surface of housing 20 causes.

Fig. 3 is seen also, is decomposition and the assembling schematic diagram of attachment structure 30.The first spring card K1 includes bottom Plate D1, the base plate D1 include relative the first face F1 (as shown in Figure 1) and the second face F2.The first face F1 of the base plate D1 Just to pcb board 40 and it is fixed on pcb board 40.The first end 31 of the spring T1 is fixed on the second face F2 of the base plate D1 On.
