Wherein: 1, plug, 2, packaging body, 3, pottery feedthrough capacitor, 4, ground path, 5, cable, 6, screen layer.
Detailed description of the invention
As shown in Figure 1, the present invention takes techniques below scheme to realize: this kind of Anti-interference cable assembly, including plug 1, packaging body 2, pottery feedthrough capacitor 3, ground path 4, cable 5 and screen layer 6, the two ends of cable 5 all connect packaging body 2, the other end of packaging body 2 connects plug 1, packaging body 2 is internal equipped with pottery feedthrough capacitor 3, pottery feedthrough capacitor 3 is along the axial distribution of packaging body 2, pottery feedthrough capacitor 3 is externally connected with ground path 4, ground path 4 is along the radial distribution of packaging body 2, and screen layer 6 is inside cable 5.
As the preferred version of the present invention, pottery feedthrough capacitor is enclosed within the contact pin of plug；The interior electrode of pottery feedthrough capacitor turns on the contact pin of plug, and external electrode turns on ground path；Ground path turns on the shell of plug；Packaging body is used to be fixed after plug, pottery feedthrough capacitor, ground path assembling；Screen layer connects conducting with 360 ° of rings of shell of plug；The inner wire of cable welds conducting with the contact pin of plug.
After 360 ° of rings of shell of the screen layer of this cable and plug connect conducting, shield completely outside whole cable assembly, it is possible to shielding external radiation interference；When the high-frequency interferencing signal of integrated system is transmitted on the contact pin of plug by the inner wire of cable, according to the characteristic of electric capacity " logical high frequency ", high-frequency interferencing signal can be decayed by pottery feedthrough capacitor, ground path, the shell of plug, user's chassis earth；According to the characteristic of electric capacity " resistance low frequency ", the low-frequency current of integrated system output or signal then contact pin normal through plug inputs other system, and high-frequency interferencing signal has decayed to not affect other system worked well, thus realizes the electromagnetic compatibility of whole system.
The Conduction Interference of integrated system can be filtered by this kind of cable assembly, simultaneously the interference of shielding external radiation, and interference free performance is higher；The parasitic interconnection inductance of pottery feedthrough capacitor is the lowest, and resonance point frequency is high, and has higher capacitance density, can realize decaying the interference signal of MHz level to GHz level.
The filter circuit of each contact pin of this cable plug is independent, can according to actual need to be with arranging filtering frequency range, strong adaptability.
The preferred embodiment of the present invention described in detail above.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to the design of the present invention without creative work.Therefore, all technical staff in the art, all should be in the protection domain being defined in the patent claims the most on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment.
