Abstract
Being suitable to transmit signal in high frequency, structure of the connector includes a print circuit board (PCB). Transferring and processing signal in high frequency, the PCB is connected to a transmission cable electrically for sending out signal. It must prevent earth conductor of the transmission cable from connecting to earth conductor of the PCB electrically in order to avoid causing transmitting out electromagnetic (EM) wave noise in high frequency together with signal. One loop of insulating material of absorbing EM wave is cladding the PCB in order to attenuate EM wave noise in high frequency generated from the PCB. Final, transmission cable and the PCB with insulating material of absorbing EM wave being covered are setup inside metal case. Moreover, conduction impedance between metal cases is reduced in order to lower electromagnetic interference.
Description
Technical field
The present invention relates to a kind of connector construction, particularly relate to a kind of connector construction with electromagnetic wave insulation absorption material with the decay electromagnetic interference.
Background technology
Increasing and people are to the progressively increase of the complexity of network application along with the internet use amount, and the manager of the information network talent and architecture network must provide the fast network data to transmit exchange velocity.Along with the requirement of more and more faster transfer rate, the signal frequency of being transmitted is also more and more higher, so high frequency connectors become the important topic of high speed data transfer based on the design of quick transmission network data.
In the design of known high frequency connectors, because propagating up and down on printed circuit board (PCB) up to 10GHz, its signal frequency can produce high-frequency noise, and since the circuit on the circuit board with will be between the metal shell of its coating can existence one potential difference, cause the frequency electromagnetic waves noise to produce resonance (Resonance) with above-mentioned metal shell, make metal shell produce an antenna (Antenna) effect, and the emission electromagnetic interference, and then influence the delivery quality of original signal.Therefore, the high-frequency noise resonance problems that the high-frequency transmission signal is produced is the problem of the required solution of high frequency connectors.
Please refer to Fig. 1, be the vertical view of known connector construction 10.As shown in Figure 1, connector construction 10 includes a circuit board 12, one Copper Foil materials 17 coating circuit plates 12, one metal shells 13, and a transmission cable 11 is connected on the circuit board 12.Because when high-frequency signal transmits in circuit board 12 and transmission cable 11, can produce the frequency electromagnetic waves noise, therefore, coat layer of copper foil 17 around the circuit board 12, to reach the metallic shield effect with the frequency electromagnetic waves noise limit in 12 of Copper Foil material 17 and circuit boards, can't spread out of outside the circuit board 12.Yet the signal that connector construction 10 is transmitted is a high-frequency signal (10GHz), and electromagnetic wave metallic shield effect effect is so effective during unlike low frequency, and good screen effect can't be arranged.In addition, because Copper Foil material 17 is that metal material is made, when high-frequency signal transmission is between circuit board 12 and transmission cable 11, can form a potential difference between the circuit on Copper Foil material 17 and the circuit board 12, this potential difference can make the frequency electromagnetic waves noise produce resonance on the contrary, and adds the strong electromagnetic phenomenon.
In known technology, the earth connection of transmission cable 11 can be connected on the circuit board 12 of connector construction 10 together with several transmission cable holding wires, and the earth connection of circuit board 12 is connected with the earth connection of transmission cable 11.Therefore, the frequency electromagnetic waves noise also can be sent in the transmission cable 11 together with high-frequency signal, and outwards spreads out of, and influences the quality of high-frequency signal.
In addition, metal shell 13 is formed by two shell combination, owing to make the restriction of module, between two housings of metal shell 13, can't combine closely usually, makes conduction resistance become big, and easily produces noise, the problem that also can cause electromagnetic interference outwards to overflow.
From the above, the electromagnetic interference problem of high-frequency signal is the important topic of this technology always, and many problems to be solved that have are arranged, and could obtain good high-frequency signal quality.The present invention is directed to above some problem, proposed effective improved connector construction.
Summary of the invention
The object of the present invention is to provide a kind of connector construction, solve the electromagnetic interference phenomenon of known technology medium-high frequency connector, this phenomenon comes from that circuit board coats a Copper Foil material and the resonance phenomena that produces the frequency electromagnetic waves noise also comes from because of causing the excessive interference and the problem of transmission cable with the derivation of frequency electromagnetic waves noise that produces noise and noise is outwards overflowed and caused of impedance in the slit of metal shell.
To achieve these goals, the invention provides a kind of connector construction, be applicable to high-frequency signal transmission, it comprises a printed circuit board (PCB), transmits and the processing high-frequency signal, and is electrically connected to a transmission cable, so that signal is spread out of.For fear of the earth connection of this transmission cable therewith the earth connection of circuit board electrically connect and cause the frequency electromagnetic waves noise to spread out of in the lump together with high-frequency signal, the present invention coats one deck electromagnetic wave insulation absorbing material on circuit board, to suppress the frequency electromagnetic waves noise that circuit board was produced.
Effect of the present invention is to utilize and coats rubber electromagnetic wave insulation absorption material on circuit board, the phenomenon of the electromagnetic interference that significantly decays, and design by the metal shell of connector construction, make two housings of metal shell be able to fluid-tight engagement, utilize a conducting adhesive cloth that two housings of metal shell are closely twined again, make the conduction resistance of whole metal shell reduce, reduce the noise problem that causes because of the housing high impedance on the traditional design.In addition, because two housings of metal shell are and combine closely, solve also that electromagnetic interference is overflowed and the problem of disturbing other circuit.Have, by changing the mode of connection of circuit board with transmission cable, the earth connection that makes both is ground connection and not interlinking respectively, makes original signal transmit and be not subjected to the frequency electromagnetic waves The noise again.
