Abstract
The utility model discloses a shelter filtering assembly which comprises a shelter-shaped metal housing. A first high-frequency filter circuit, a low-frequency filter circuit and a second high-frequency filter circuit which are sequentially connected are disposed in the shelter-shaped metal housing. A front side and a back side of the shelter-shaped metal housing are respectively provided with multipath input interfaces and multipath output interfaces, wherein the multipath input interfaces are connected with input ends of the first high-frequency filter circuit, and output ends of the second high-frequency filter circuit are connected with the multipath output interfaces, and thus filtering of multipath input signals (e.g. power source signals and control signals) can be realized simultaneously. As a result, the shelter filtering assembly has multiple functions and high integration level, and when filtering of multipath input signals is required, only one shelter filtering assembly is needed to complete the work that should be finished by multiple filtering assemblies.
Description
Technical field
The utility model relates to a kind of filter apparatus, relates in particular to a kind of shelter filtering unit.
Background technology
Filtering unit is a kind of novel assembling device of being applied in recent years.It can suppress electric network noise effectively, improves the antijamming capability of electronic equipment and the reliability of system, can be widely used in fields such as communication and navigation, command system, electronic countermeasures, radar, computer equipment, TT﹠C system.The battlefield electromagnetic environment is complicated and changeable in the modern war, and individual system or equipment are had relatively high expectations, so must do particular processing to each parts, installs filtering unit additional.The use of filtering unit can not only reduce the radianting capacity of self, the more important thing is the strong electromagnetic ability that has improved the anti-external world, and the battlefield adaptive capacity of system is improved greatly.
Yet existing filtering unit generally can only carry out filtering to the single channel input signal, when the filtering simultaneously of needs multichannel input signal, needs a plurality of filtering units to work simultaneously, so its function singleness, integrated level are lower.
The utility model content
The purpose of this utility model is to provide the shelter filtering unit that a kind of integrated level height, function are many, can carry out filtering to the multichannel input signal simultaneously.
For achieving the above object, the utility model provides a kind of shelter filtering unit, comprise shelter shape metal shell, be provided with first high-frequency filter circuit, low-frequency filter circuit and second high-frequency filter circuit that link to each other successively in the described shelter shape metal shell, both sides, described shelter shape metal shell front and back correspondence respectively are provided with multichannel input interface and multichannel output interface, described multichannel input interface links to each other with the input of described first high-frequency filter circuit, and the output of described second high-frequency filter circuit links to each other with described multichannel output interface.
Shelter filtering unit of the present utility model, described multichannel input interface comprise power supply input aviation plug, oily machine control input aviation plug, oil start input aviation plug, oily dynamo-electric source input aviation plug, warm braw control input aviation plug, AIR COND SIG Air Conditioner Singnal input aviation plug, air-conditioning power supply input aviation plug, intercom input aviation plug.
Shelter filtering unit of the present utility model, described multichannel output interface comprise power supply output aviation plug, oily machine control output aviation plug, oil start output aviation plug, oily dynamo-electric source output aviation plug, warm braw control output aviation plug, AIR COND SIG Air Conditioner Singnal output aviation plug, air-conditioning power supply output aviation plug, intercom output aviation plug.
Shelter filtering unit of the present utility model, described first high-frequency filter circuit and described second high-frequency filter circuit are the feed-through capacitor feed-through filter.
Shelter filtering unit of the present utility model comprises shelter shape metal shell, be provided with first high-frequency filter circuit, low-frequency filter circuit and second high-frequency filter circuit that link to each other successively in the shelter shape metal shell, both sides, shelter shape metal shell front and back correspondence respectively are provided with multichannel input interface and multichannel output interface, the multichannel input interface links to each other with the input of first high-frequency filter circuit, and the output of second high-frequency filter circuit links to each other with the multichannel output interface.Thereby realized simultaneously the filtering to multichannel input signal (for example power supply signal and control signal), therefore, its function is many, integrated level is high, and when the filtering simultaneously of needs multichannel input signal, only need a shelter filtering unit just can finish the work that a plurality of filtering units just can be finished, therefore, also reduced equipment cost.
