[0041] Hereinafter, the present disclosure will be described in more detail with reference to the accompanying drawings.
[0042] In the following description, in order to facilitate the description of the specification, only the suffixes "module" and "unit" are added, and the suffixes "module" and "unit" can be used compatible with each other.
[0043] In addition, although the embodiments will be described in detail below with reference to the drawings and the contents marked in the drawings, the embodiments are not limited thereto.
[0044] image 3 Is a view showing the structure of a two-stage linear filter 100 according to an embodiment.
[0045] Below, will refer to image 3 The two-stage linear filter 100 according to one embodiment is described in detail.
[0046] Such as image 3 As shown, the two-stage linear filter 100 according to this embodiment includes a bobbin 110, a first coil 120, a second coil 130, an input line 140, an output line 150, and a connecting line 160.
[0047] The bobbin 110 may have two surfaces, and a coil is wound around the two surfaces. In particular, the bobbin 110 may have vertically divided cores (not shown) formed on these surfaces so as to wind a coil around these surfaces.
[0048] For example, such as image 3 As shown, the core may be formed on the surface of the bobbin 100 such that the first coil 120 is wound around the top surface of the bobbin 100 and the second coil 130 is wound around the bottom surface of the bobbin 100.
[0049] At the same time, one end of the first coil 120 is connected to the input line 140 to which the alternating current is applied, and the opposite end corresponding to this end is connected to the connection line 160 for connecting the first coil 120 to the second coil 130.
[0050] In addition, one end of the second coil 130 is connected to the output line 150 for outputting noiseless alternating current, and the opposite end corresponding to the end connected to the output line 150 is connected to the connection line 160.
[0051] At the same time, the connecting wire 160 is placed between the first coil 120 and the second coil 130 to electrically connect the first coil 120 to the second coil 130 as described above. The connection line 160 includes a capacitor connection unit 161 so that the connection line 160 can be connected to the capacitor 200 for noise removal and filtering purposes.
[0052] The capacitor 200 may include various capacitors for linear filtering. Preferably, the capacitor 200 may include an X capacitor. Alternatively, the capacitor 200 may include a plurality of capacitors. In addition, the capacitor 200 may be connected to a circuit including various devices. Therefore, this embodiment is not limited to one capacitor.
[0053] At the same time, according to the two-stage linear filter of this embodiment, the input line 140 for inputting AC power includes a live line 141 and a neutral line 142. Therefore, the first coil 120 may include a first input coil 121 and a second input coil 122 corresponding to the live wire 141 and the neutral wire 142.
[0054] The first input coil 121 is connected to the live wire 141 for inputting electric power and is connected to the second coil 130 through the connection wire 160. Therefore, the first input coil 121 may perform a linear filtering operation on the power input through the live wire 141 and may output the filtered input power to the second coil 130 through the capacitor 200.
[0055] In addition, the second input coil 122 is connected to the neutral line 142 for inputting power and is connected to the second coil 130 through the connection line 160. Except for replacing the live wire 141 with the neutral wire 142, the second input coil 122 has the same function as the first input coil 121.
[0056] At the same time, similar to the input line 140, the output line 150 of the integral two-stage linear filter according to one embodiment includes a live line 151 and a neutral line 152. Therefore, the second coil 130 may include a first output coil 131 and a second output coil 132 corresponding to the live wire 151 and the neutral wire 152, respectively.
[0057] One end of the first output coil 131 is connected to the first coil 120 through the connecting wire 160, and the opposite end corresponding to the end is connected to the live wire 151 of the output wire 150. Therefore, the first output coil 131 may perform a quadratic linear filtering operation on the power input from the first coil 120 through the connection line 160 and output the filtered power through the live wire 151 of the output line 150.
[0058] In addition, as described above, one end of the second output coil 132 is connected to the first coil 120 through the connection line 160, and the opposite end corresponding to this end is connected to the neutral line 152 of the output line 150. Therefore, the second output coil 132 may perform a quadratic linear filtering operation on the power input from the first coil 120 through the connection line 160 and output the filtered power through the neutral line 152 of the output line 150.
[0059] Meanwhile, the integral two-stage linear filter according to one embodiment may include a housing that supports the linear filter and is used for mounting on the inverted substrate. The housing covers the side of the bobbin 100, thereby preventing the bobbin 100 from shaking, and at the same time preventing interference of separated peripheral components caused by external vibration of the electrical appliance or interference of wires disposed adjacent to the coils 120 and 130.
[0060] In addition, the housing is provided with a connector (not shown) on one side thereof, and the connector connects the live line 141 and the neutral line 142 of the input line 140 and the live line 151 and the neutral line 152 of the output line 150.
[0061] In this case, the connector may include four connectors for connecting the live line 141 and the neutral line 142 of the input line 140 and the live line 151 and the neutral line 152 of the output line 150, and may be sequentially arranged in one of the housings. Side. In addition, the connectors for the live line 141 and the neutral line 142 of the input line 140 are provided on one side of the housing, and the connectors for the live line 151 and the neutral line 152 of the output line 150 are provided on the opposite side of the housing, thereby The arrangement of wires and the pin connection of the input/output terminals can be easily performed. Alternatively, the live line 141 of the input line 140 and the live line 151 of the output line 150 are arranged on one side of the housing, and the neutral line 142 of the input line 140 and the neutral line 152 of the output line 150 may be arranged on opposite sides of the housing.
[0062] The connector arrangement of the housing facilitates pin connection and wire arrangement. For example, connectors for the input line 140 and the output line 150 may be provided on one side of the housing. Accordingly, a connector for the capacitor 200 may be additionally provided on the opposite side of the case, so that the capacitor 200 may be connected to the capacitor connection unit 161.

In this case, the bobbin 110 is additionally provided on the top surface thereof with a protruding part 170 that separates the first input coil 121 from the second input coil 122.
[0066] Similarly, the bobbin 110 is provided on its bottom surface with a protruding part 171 that separates the first output coil 131 from the second output coil 132.
