Abstract
The utility model relates to a filtering output connector of DC power supply for providing large DC power to communication equipments, which comprises input connection unit and output connection unit. The utility model is characterized by a filter circuit unit connected between the input connection unit and output connection unit in series. The input and output connection units and filter circuit unit are disposed in a box, with the input and output connection units respectively disposed on two sides of the box. The utility model can transmit large DC power to equipment without attenuation, and simultaneously greatly attenuate interference signal from power supply to effectively lower interference on transmission and radiation of communication system to satisfy electromagnetic compatibility certification, and also prevent interference signal generated by equipment from entering the power supply. The compact and integral box type plug connection structure has reliable connection, convenient usage and installation; and can satisfy functional requirements of PCB installation and power connection.
Description
Technical field
The utility model relates to a kind of DC power filter output connector that communication equipment provides big DC power supply power that can be.
Background technology
Along with the raising of communication system complexity and integrated level, the power of communication system equipment is increasing, and the big electric current input of system equipment is also more and more higher with the requirement that reliably is connected.In addition, in the compatible authentication of installation electromagnetical, EMI (conduction, radiated interference) testing performance index is an important step, and power port and the power line one of the main reasons of equipment EMI index exceeding standard often, because the out connector of existing DC power supply is not taked corresponding technical measures, system equipment can be subjected to a certain degree conducting influence with radiated interference by power line.Therefore, design has that reliable big electric current input connects and the power filter connector of EMI filter function is very necessary.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of DC power filter output connector reliable and the strong filter function of tool that connects at the deficiency of above-mentioned prior art existence.
The technical scheme that the utility model adopted is: comprise input linkage unit and output linkage unit, its difference is serial connection filter circuit unit between input linkage unit and output linkage unit, input, output linkage unit and filter circuit unit are installed in the box body, and a side of box body is provided with the input linkage unit, and the opposite side of box body is provided with the output linkage unit.
Press such scheme, described input linkage unit is that multicore connects socket; Described output linkage unit is for connecting electric wire; Described filter circuit unit is reflective low pass filter; Described box body is a metal case.
The beneficial effects of the utility model are: 1, can will be sent to equipment than big direct current power undampedly, the interference signal that simultaneously big high attenuation is imported into through power supply, having solved the power line with big direct current flow equipment connects and the EMI filtering problem, effectively reduce conduction and radiated interference, equipment is met and authenticate by electromagnetic compatibility test to communication system equipment; 2, can also suppress the harassing and wrecking signal that system equipment itself produces, prevent that it from entering power supply; 3, the boxlike connected structure of compact one not only connects reliably, and easy to install and use, can satisfy the functional requirement that single-deck formula (PCB) is installed and power supply connects.
