Embodiment
The first embodiment of the present invention is as shown in Fig. 2 a, and it comprises a flat plane antenna 210, a dividing plate 240, a circuit board 220, one second contact pin 250 and a joint 230.Flat plane antenna 210 has an antenna ground face 212 and an acceptance division 211, and this acceptance division 211 can be a metallic plate.Dividing plate 240 has first baffle surface 241 and second partition surface 242, the first baffle surface 241 contact with antenna ground face 212.Circuit board 220 has a circuit board ground plane 221, a circuit is provided with a face 222 and a board circuit (not graphic), and circuit board ground plane 221 contacts with second partition surface 242, and board circuit is located at circuit face 222 is set.Joint 230 collocation bases 232 join with circuit board 220.Joint 230 has first contact pin, 231, the first contact pins 231 and passes circuit board 220, and is fixed in circuit board ground plane 221, and first contact pin 231 also is connected with board circuit.Second contact pin 250 is passed to board circuit by flat plane antenna 210, dividing plate 240 and circuit board 220, the second contact pins 250 with the signal that flat plane antenna 210 is received.
Above-mentioned signal can be wireless microwave signal, and above-mentioned joint 230 can be radio-frequency joint.
The mode combination that flat plane antenna 210, dividing plate 240 and circuit board 220 can lock, the mode that its formality is welded is easy, and can change the part (flat plane antenna 210 or circuit board 220) that damages separately.
Refer again to Fig. 2 a, the present invention utilizes first contact pin 231 to replace coaxial wire, so that the outgoing position of signal in the bottom, has been taken into account attractive in appearance and reduce electromagnetic interference, and therefore the cost of first contact pin 231 can reduce the whole cost of signal receiving device much smaller than coaxial wire.On actual assembled, because first contact pin 231 is difficult for and circuit welds, so the present invention is located at the welding fixing point of first contact pin 231 on the circuit board ground plane 221.With reference to Fig. 3, for convenient welding, be formed with a metal ring 224 on the circuit board ground plane 221, and connect and ground connection for fear of first contact pin 231 and electric conducting material 223, metal ring 224 outer placing are formed with an annular gap 225 especially.Confession first contact pin 231 on the circuit board 220 is provided with face 222 by the through hole to circuit board ground plane 221 from circuit, its inwall is coated with electric conducting material (as copper), and the board circuit that metal ring on itself and the circuit board ground plane 221 and circuit are provided with on the face 222 links.When assembling, only need guarantee that first contact pin 231 is welded in the position of metal ring on the circuit board ground plane 221, just can finish its installation, first contact pin 231 is connected with board circuit, its assembling mode is very easy, and stability is high.
With reference to Fig. 4 a, contact with dividing plate 240 and cause short circuit for fear of first contact pin 231, can on second partition surface 242, one insulating trip 261 be set the welding position corresponding to first contact pin 231, contact with second partition surface 242 to prevent first contact pin 231.With reference to Fig. 4 b, it also can form a preformed hole 262 in the welding position corresponding to first contact pin 231 on second partition surface 242, and the mode that preformed hole 262 can punching press forms.Or as shown in Fig. 4 c, preformed hole 262 can also punching press mode in addition directly be formed on the dividing plate 240.It also can make the top of first contact pin 231 be lower than the surface of electric conducting material 223, and directly avoid first contact pin 231 to contact with dividing plate 240 when first contact pin 231 is set.
Above-mentioned many variations also can be applicable to the situation of the no dividing plate of Fig. 2 b, the size of reduced plan antenna for example, or insulating trip is set and prevents design such as the first contact pin ground connection, but its signal quality is not if there is the situation that dividing plate is set.In addition, the present invention also can cast out the structure of joint 230 and adopt the mode of welding as wiring among Fig. 1 130, only adopts baffle plate configuration to simplify assembly program.
Signal receiving device of the present invention can effectively reduce cost, and has taken into account the communication quality of product simultaneously.Its framework is simple, assembling is easy, and can effectively reduce the overall volume of device.
Though the present invention describes with reference to current specific embodiment, but those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the present invention, under the situation that does not break away from spirit of the present invention, also can make the variation and the modification of various equivalences, therefore, as long as variation, the modification to the foregoing description all will drop in the scope of claims of the present invention in connotation scope of the present invention.
