The invention relates to the technical field of remote control, in particular to an intelligent high-voltage large-current rectification system, whether the rectification process is qualified or not is analyzed according to the current value after rectification and filtering, secondary judgment is carried out based on the fluctuation condition of the current value after rectification in historical data, and the reason for the unqualified rectification process is analyzed. According to the method, the filtering process is analyzed to be unqualified when the variance of the current value of the historical data is large, the ripple coefficient is reduced by increasing the frequency of the signal source, so that the filtering effect is improved, but the frequency characteristic of the circuit can be influenced by the change of the frequency of the signal source, so that the filtering effect is improved. When the power supply frequency is close to the signal source frequency, the frequency mixing phenomenon is easily generated, and the signal quality and accuracy are influenced, the signal source frequency is adjusted according to the difference value between the signal source frequency and the power supply frequency, so that the frequency mixing phenomenon is avoided, and the signal filtering effect is improved while the signal quality is ensured.

The invention relates to a PCIE (Peripheral Component Interconnect Express) connector, which comprises a plastic main body, terminals, a card inserting plate, a slot and a bottom, the terminal is arranged in the plastic main body, and the card inserting plate is electrically connected with the terminal; two sides of the slot are provided with placing grooves, and the placing grooves corresponding to the grounding terminals are provided with open holes. The terminal is additionally provided with a second bending part; a bulge is arranged at the bottom of the plastic main body; two sides of the terminal are provided with barb structures. The beneficial effects of the invention are that the holes are formed in the placing grooves corresponding to the grounding terminals, so that the signal terminals and the grounding terminals are located in different electromagnetic field environments, and the crosstalk interference of the terminals is reduced; the terminal is additionally provided with the second bending part to disperse the stress of the first contact end, and the distance between the terminal and the card inserting plate is closer, so that the characteristic impedance of the connector is reduced; the barb structures are arranged on the two sides of the terminal in a staggered manner, so that the plastic main body can be prevented from warping; and the bulges at the bottom of the plastic main body are used for spacing the shoulders of the terminals, so that the short circuit phenomenon is avoided, and the performance and the service life of the connector are not influenced.

The present application provides a cable electrical connection device, which includes a connector, a flat wire and a grounding sheet. The flat wire is connected to the connector, and one end of the flat wire defines a soldering end. The flat wire includes an insulating body, a plurality of conductive cores, a shielding layer and an insulating layer. The conductive cores are embedded in the insulating body, one end of each of the conductive cores protrudes from the soldering end and is soldered to the connector, and the plurality of conductive cores includes a grounding core. The shielding layer is wrapped outside the insulating body. The insulating layer is wrapped outside the shielding layer. The shielding layer protrudes from the insulating layer at the soldering end to form a grounding portion. The grounding sheet includes an attaching portion and a grounding claw. The attaching portion is attached to the outside of the grounding portion of the shielding layer. The grounding claw extends from one side of the attaching portion and is electrically connected to the grounding core.
