Description
Technical field
The utility model relates to electric fittings field, particularly relates to a kind of four-quadrant feedback fil-ter.
Background technology
Filter is a kind of passive bidirectional network, and its one end is power supply, and the other end is load.The principle of filter is exactly a kind of impedance network: the impedance of power-supply filter input, outlet side and power supply and load-side is larger, more effective to the decay of electromagnetic interference.Such as Chinese invention patent " power-supply filter ", application number is 20120518582.3, discloses and comprises iron core, coil holder and base, and the middle part of base is provided with the coil holder groove corresponding with coil holder, and the both sides of base are provided with the iron core groove corresponding with iron core; It is characterized in that described iron core inwall cavity arranges crosspiece, iron core forms " order " character form structure; The wall that the radial width of crosspiece is less than iron core is wide.The advantages such as it is good that this decoupling zero has compatible result, and antijamming capability is strong.But find from use actual conditions, its crystallized ability is short of to some extent, general structure adopts bolt and screw by the mode that screw thread is fixing, but its be installed on dismounting will be not too convenient.
Utility model content
The technical problem that the utility model mainly solves is to provide a kind of four-quadrant feedback fil-ter, and it is reasonable in design, and structure is simple, solves and installs inconvenient and that the flexible performance of fixed structure is not high problem.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is to provide a kind of four-quadrant feedback fil-ter, comprises housing, power pin, load pin and filter unit; The tank that the interior separation of described housing becomes several independent; Described filter unit is placed with in described tank; The outside wall of described housing is also provided with described power pin and load pin; Described power pin is connected with corresponding filter unit respectively with load pin; Described housing is also provided with for fixing U-shaped fixture block; Described U-shaped fixture block comprises the clamping plate established and bottom connecting plate relatively; Described bottom connecting plate and described housing hinge; Described clamping plate are provided with screw; Screw rod is combined with in described screw; Described filter unit comprises electric capacity, resistance and inductor; Described power pin and load pin are positioned on two sides relative on described housing.
Preferably, described U-shaped fixture block is fixed on two sides adjacent with front on the housing; Each side is equipped with two described U-shaped fixture blocks.
Preferably, the insulating material that described housing is formed in one, is provided with the draw-in groove installing location for described filter unit in described tank.
The beneficial effects of the utility model are: provide a kind of four-quadrant feedback fil-ter, have used the higher clamping mode of flexibility instead as fixed structure, have improve its mobility, and this structure is convenient to install, and be easy to safeguard, applicable installation under circumstances.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of four-quadrant feedback fil-ter of the utility model;
Fig. 2 is the internal structure part schematic diagram of four-quadrant feedback fil-ter;
In accompanying drawing, the mark of each parts is as follows: 1, housing; 2, power pin; 3, load pin; 4, tank; 5, U-shaped fixture block; 6, clamping plate; 7, bottom connecting plate; 8, screw rod; 9, draw-in groove.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection range of the present utility model.
Refer to attached Fig. 1 and 2, the utility model embodiment comprises:
A kind of four-quadrant feedback fil-ter, comprises housing 1, power pin 2, load pin 3 and filter unit; The tank 4 that the interior separation of described housing 1 becomes several independent; Described filter unit is placed with in described tank 4; Described filter unit comprises electric capacity, resistance and inductor; The draw-in groove 9 installing location for described filter unit is provided with in described tank 4.The draw-in groove 9 of location can make filter unit install quickly and accurately, and error is less likely to occur, and improves the working (machining) efficiency of product.The insulating material that described housing 1 is formed in one, the outside wall of described housing 1 is also provided with described power pin 2 and load pin 3; Described power pin 2 and load pin 3 are positioned on two sides relative on described housing 1; Described power pin 2 is connected with corresponding filter unit respectively with load pin 3.Described housing 1 is also provided with for fixing U-shaped fixture block 5; Described U-shaped fixture block 5 is fixed on two sides adjacent with front on described housing 1; Each side is equipped with two described U-shaped fixture blocks 5.Described U-shaped fixture block 5 comprises the clamping plate 6 established and bottom connecting plate 7 relatively; Described bottom connecting plate 7 is hinged with described housing 1; Described clamping plate 6 are provided with screw; Screw rod 8 is combined with in described screw.As shown in the figure, utilize U-shaped fixture block to clamp fixture, by screwing the object that screw rod reaches fastening, structure is simple, easy to operate.Especially in the use procedure of reality, easy for installation, improve the mobility of structure, and this structure is easy to safeguard, applicable installation under circumstances.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
