Description
Technical field
The utility model relates to a kind of cover plate of casing and has the electronic installation of this casing, particularly relates to a kind ofly being easy to for the cover plate of the casing of printed circuit board antenna assemblies and dismounting and having the electronic installation of this casing.
Background technology
As Fig. 1, Fig. 2 and shown in Figure 3, general adapter (the Digital Media Adaptor of Digital Media, DMA) 1 comprises a casing 11, casing 11 comprises the housing 111 of a metal material, and the plastic material cover plate 113 in order to the side 112 that is connected to housing 111, the inner surface 114 of cover plate 113 is equipped with a PCB antenna in order to the video-audio signal that receiving computer spread out of (PCB Antenna) 115.Cover plate 113 comprises that four are convexly set in the grab 116 of inner surface 114 relatively symmetrically, and each grab 116 has an arm 117 that is protruded out by inner surface 114 inwardly, and a hook portion 118 that is formed at arm 117 ends.
When desire is assembled in cover plate 113 with PCB antenna 115, with hook portion 118 pressuring directions of PCB antenna 115 towards each grab 116, when PCB antenna 115 is conflicted the inclined-plane 119 of hook portion 118, grab 116 outwards can be strutted, circuit board antenna 115 to be printed is by after the hook portion 118, hook portion 118 reset because of the reseting elasticity of arm 117 and clip in PCB antenna 115 back sides, at this moment, the arm 117 of grab 116 is connected to the both sides, front and back of PCB antenna 115, and two shell fragments 120 of cover plate 113 are connected to the both sides up and down of PCB antenna 115, make PCB antenna 115 be fastened in the inner surface 114 of cover plate 113.When desire is separated cover plate 113 with PCB antenna 115, need outwards to pull simultaneously the hook portion 118 of each grab 116, make it break away from PCB antenna 115 back sides after, PCB antenna 115 can be separated.
Yet, in order to make PCB antenna 115 more be posted by the inner surface 114 of cover plate 113 and away from the housing 111 of metal material, to improve the receiving efficiency of PCB antenna 115, so the arm 117 of grab 116 can shorten its length when design, make PCB antenna 115 can be posted by the inner surface 114 of cover plate 113, but this kind design can cause the arm of force of grab 116 to shorten, cause grab 116 hard and do not have elasticity, cause being difficult in PCB antenna 115 dismounting, moreover the improper meeting of the application of force in the disassembly process causes the situation of grab 116 fractures to produce.So, the inner surface 114 of cover plate 113 is provided with fin 121 for PCB antenna 115 butts, make the arm 117 of grab 116 when design, can maintain certain length at least by this to have enough elasticity, but thus, just can't make PCB antenna 115 abut in the inner surface 114 of cover plate 113 fully.
In addition, other fixed forms in order to fixed printed circuit board antenna 115 also include the mode of screw lock locking, and the fixing mode of taping, but aforementioned dual mode also can cause assembled component to increase and the problem of raising manufacturing cost except meeting increases the man-hour of assembling.
