Embodiment
The utility model provides a kind of shielding case structure, clearer, clear and definite for making the purpose of this utility model, technical scheme and effect, below the utility model is further described.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 2, the structural representation that Fig. 2 is the preferred embodiment of the utility model shielding case structure, as shown in the figure, it comprises: ring frame 200 and be arranged on the muscle 210 on ring frame 200 and be arranged on muscle 210 and/or ring frame 200 on suction ripple layer 220.
In the utility model, ring frame 200 is for covering the various electronic components on circuit board, the effect of muscle 210 is can produce the electronic component of radiation on the buffer circuit plate, because the segment section on muscle 210 or ring frame 200 is to prevent from causing the electronic component short circuit there is no the shell foot of design with the circuit board contact, do not have the function of radiation-screening, so this muscle 210 and/or above ring frame 200 correspondence position be provided with the suction ripple layer 220 for radiation-screening, and this suction ripple layer 220 is nonconducting, can realize both shielding electronic components radiation so utilize this muscle 210 or ring frame 200, can not cause again the effect of short circuit between electronic component.Above-mentioned and/or the meaning refer to: arrange separately on ring frame, arrange separately on muscle, arrange on ring frame and muscle simultaneously and inhale ripple layer 220, as long as can realize that radiation-screening all can.
Below in conjunction with Fig. 2,3 and 4 pairs of structures of the present utility model, be specifically described.
Shielding case structure of the present utility model is fixed on metal sheet, is provided with a plurality of haptic elements 230 for ring frame 200 is contacted with circuit board on described ring frame 200.Ring frame 200 in the utility model can adopt and stretch or other structures.
Because being to utilize suction ripple layer 220 and metal parts, improvements of the present utility model jointly carry out radiation-screening, so the shape for ring frame 200 can arrange according to specific needs, for example be set to squarely, circular or some other is irregularly shaped, arrange or muscle is not set all can.
At muscle 210 and/or the suction ripple layer 220 above ring frame 200, by symmetrical pinch 240 or crossbeam 250 or other fixed forms, fix, the shape of symmetrical pinch 240 is that an end is connected to muscle 210 and/or above ring frame 200, the unsettled setting of the other end, and the middle part of symmetrical pinch 240 arranges the lug boss of outwardly convex (having elasticity), thereby utilization has flexible lug boss, suction ripple layer 220 is supported at muscle 210 or above ring frame 200.More preferably, symmetrical pinch 240 is symmetrical arranged, thereby fixedly secure, inhales the ripple layer.
