Abstract
The utility model discloses an integrated wide-band power supply wave filter, which comprises a power supply filter (1), an installation plate (2) arranged on side of a shell in the power supply filter (1), an electric connector (3) and a melting breaker (4) arranged on the installation plate (2), wherein, the end of the electric connector (3) and the melting breaker (4) extend into the power supply filter (1). Output of the power supply filter (1) is educed by two cross capacitances (5). A conductive cushion (6) is arranged between the electric connector (3), the melting breaker (4) and the installation plate (2). The utility model is of compact structure, good whole performance, good electro-magnetic airproof performance and wide frequency range of effective filtering.
Description
Technical field
The utility model relates to filter, especially relates to a kind of integrated wideband power supply filter.
Background technology
Make up in the anti-electromagnetic interference at electric connector and power-supply filter, shielding, ground connection, filtering are the three big main method that solve electromagnetic interference.And power-supply filter is widely used as solving conduction emission (CE) assembly the most frequently used, the most effective anti-electromagnetic interference, the power supply of equipment is introduced by electric connector at present, being connected to power-supply filter is a kind of common mode, in order to give full play to the usefulness of power-supply filter, require power-supply filter to install nearby, owing to be subjected to the restriction of device structure, particularly carrying out being difficult to accomplish this point when electromagnetic compatibility is reinforced.In addition, also will adopt switch, fuse etc. in the equipment, these devices all should be made anti-electromagnetic interference and handle, otherwise are difficult to satisfy the requirement of electromagnetic radiation.But the present situation of most of equipment is to adopt power-supply filter, electric connector, fuse to install respectively, and each takes the mode of anti-electromagnetic interference measure.
Summary of the invention
The purpose of this utility model provides a kind of compact conformation, integrated wideband power supply filter that overall performance is good.
In order to achieve the above object, the utility model adopts following technical scheme: a kind of integrated wideband power supply filter, comprise power-supply filter, side at the power-supply filter shell is equipped with mounting panel, electric connector and fuse are installed on mounting panel, the afterbody of electric connector and fuse stretches in the power-supply filter, draws by two feedthrough capacitors at the output of power-supply filter.
Between described electric connector, fuse and the mounting panel conductive gasket is installed.
The utility model is integrated in one electric connector, power-supply filter, fuse, makes the line of connector and power-supply filter the shortest, and the performance of power-supply filter obtains best utilization.In addition, install core-through capacitor additional, the power-supply filter high end performance is improved, effectively the frequency range broadening of filtering at the output of power-supply filter.In addition, side at the power-supply filter shell increases a mounting panel, electric connector and fuse are contained on the mounting panel, its afterbody stretches into filter shell inside, the inner low pass power-supply filter of forming by inductance capacitance, output is drawn by two feedthrough capacitors, and such structure makes this filter construction compactness, and overall performance is good.Simultaneously, install conductive gasket additional, help the electromagnetic sealing of filter in the contact position of connector and fuse dress and mounting panel.
The utility model has the advantages that: compact conformation, overall performance is good, and electromagnetic sealing is good, effectively the frequency range broadening of filtering.
