Flexible circuit board 4 is communicated to above circuit board 6, finally realizes the conducting between the first metal shell 1 and circuit board 6, so that real
The transmission of existing radiofrequency signal.
Further, spring plate 5 is set to connect the first metal shell 1 and flexible circuit board 4, spring plate 5 can play soft
Property connection effect.Also, the coupling force between the first metal shell 1 and flexible circuit board 4 and external force are played slow
The effect of punching.
Compared with rigid connection, flexible connection can when the first metal shell 1 is subject to external force to act on, buffer external force without
External force is directly transferred to flexible circuit board 4 (rigid connection is that external force directly is transferred to flexible circuit board 4), so as to play
Protect the effect of flexible circuit board 4.
It refer to shown in Fig. 5 and Fig. 6, the one side of spring plate 5 is equipped with the first solder joint 51, and flexible circuit board 4 is positioned at the
One end in one accommodating chamber is equipped with gold-plated area 43 (as shown in Figure 8).The opposite flank of elastomer 5 is equipped with the second solder joint 52.
Specifically, between flexible circuit board 4 and spring plate 5, by the contact with the first solder joint 51 of gold-plated area 43, realize soft
Being electrically connected between property wiring board 4 and spring plate 5.And since the first metal shell 1 is metal antenna, the first metal shell 1 can
Directly to be contacted with the second solder joint 52, so as to fulfill being electrically connected between spring plate 5.
Further, in the present embodiment, gold-plated area 43 is directly set in flexible circuit board 4, for 5 phase of spring plate
Connection.Miscellaneous part need not be set, for connecting flexible circuit board 4 and spring plate 5, therefore, save space, realized close
Layout.
Shown in Figure 7, one end that flexible circuit board 4 is located in the second accommodating chamber is equipped with connector 41.
Specifically, connector 41 is used as conduction device, and flexible circuit board 4 can be caused to connect by connector 41 and circuit board 6
It is logical.So as to which by the conducting between connector 41 and circuit board 6, final realize carries out between the first shell 1 and circuit board 6
Signal transmission.
Further, one end that flexible circuit board 4 is located in the second accommodating chamber is additionally provided with circuit element 42.The circuit element
42 can be got up by connector 41 and the conducting of circuit board 6, that is to say, that flexible circuit board 4 can be realized between circuit board 6
Integrated matching feature, to reduce the area occupied of component on circuit board 6.Further, which can be day
The match circuit of antenna, to adjust the frequency of radiofrequency signal, is so arranged in flexible circuit board 4 by the match circuit of line,
The area of circuit board 6 can be reduced, is conducive to the design of line traffic control miniaturized structure.These are all not available for circular coaxial cable
's.
Refer to shown in Fig. 9 and Figure 10, insulating frame 3 is equipped with mounting hole 31, it is preferable that mounting hole 31 is opened in insulating frame
