The inductor 100 and the air conditioner according to the embodiment of the present invention are described below with reference to the accompanying drawings. Inductor 100 is used to electrically connect to a circuit board that may be used on any device requiring a circuit board, including but not limited to an air conditioner. For convenience of description, the following description will be made only by taking an air conditioner as an example.

As shown in fig. 1 to 6, according to the inductor 100 of the embodiment of the present invention, the air conditioner includes a circuit board, and the inductor 100 includes a fixing base 1, a magnetic member 2 and a coil 5.

The fixed seat 1 is provided with a first end surface 11 and a second end surface 12 opposite to the first end surface 11; the magnetic part 2 is arranged on the first end surface 11 of the fixed seat 1, and the magnetic part 2 is of a hollow structure; the coil 5 is wound on the magnetic part 2, a first end of the coil 5 extends out of the second end face of the fixed seat 1 from the outer side of the magnetic part 2 to define a first pin 3, a second end of the coil extends out of the second end face of the fixed seat 1 from the inner side of the magnetic part 2 to define a second pin 4, the first pin 3 and the second pin 4 are suitable for being connected with a circuit board, and the second pin 4 is located on a connecting line of the first pin 3 and the geometric center of the magnetic part 2.

Here, since the magnetic member 2 has a hollow structure, the outer side of the magnetic member 2 may be understood as the outward side of the outer surface of the magnetic member 2, and the inner side of the magnetic member 2 may be understood as the inward side of the inner surface of the magnetic member 2. Here, the magnetic member 2 may be a circular ring or a polygonal ring.

It will be appreciated that the holder 1 may be used to hold and carry the magnetic element 2 and the coil 5; the coil 5 and the circuit board can be electrically connected through the first pin 3 and the second pin 4. Here, one of the first pin 3 and the second pin 4 is an input terminal of the coil 5, the other of the first pin 3 and the second pin 4 is an output terminal of the coil 5, and when the first pin 3 is an input terminal, the second pin 4 is an output terminal; when the first pin 3 is an output terminal, the second pin 4 is an input terminal, which is not particularly limited, and thus, the inductor 100 may be facilitated to perform an electrical function.

The inductor 100 is used in an air conditioner, and has a large current and a high voltage, and when the inductor works, a large voltage drop is generated between an input end and an output end, and the first pin 3 and the second pin 4 are too close to cause high-voltage discharge ignition, so that the first pin 3 is positioned outside the magnetic part 2, and the second pin 4 is positioned inside the magnetic part 2, so that the distance between the first pin 3 and the second pin 4 can be increased, and the high-voltage discharge ignition caused between the first pin 3 and the second pin 4 can be avoided.

The first pin 3 may be located at any position outside the magnetic member 2, and the second pin 4 may be located on a connection line between the first pin 3 and the center of the magnetic member 2, so that the inductor 100 has better electromagnetic compatibility.

The utility model discloses a large amount of experiments have been carried out respectively with first inductor and second inductor to the utility model, have reachd the frequency-disturbance power curve chart like the inductor that fig. 3-fig. 4 show, first inductor is that second pin 4 is not located the line at first pin 3 and magnetic part 2's center, the second inductor is that second pin 4 is located the line at first pin 3 and magnetic part 2's center, also the second inductor does the utility model discloses an inductor 100. Fig. 3 is a frequency-disturbance power curve of the first inductor, and fig. 4 is a frequency-disturbance power curve of the second inductor, that is, the inductor 100 of the present invention.

In fig. 3, the abscissa is the frequency of the first inductor, the unit is MHz, the ordinate is the disturbance power of the first inductor, the line type L1 is the quasi-peak disturbance power limit, the line type L2 is the average disturbance power limit, the line type L3 is the peak measured disturbance power value, and the line type L4 is the average measured disturbance power value. The abscissa of fig. 4 is the frequency of the second inductor in MHz, the ordinate is the disturbance power of the second inductor, the line G1 is the quasi-peak disturbance power limit, the line G2 is the mean disturbance power limit, the line G3 is the peak measured disturbance power value, and the line G4 is the mean measured disturbance power value.

The fact that the peak value measured disturbance power value does not exceed the quasi-peak value disturbance power limit value can be understood as that the electromagnetic capacity compatibility of the inductor 100 is qualified, and the fact that the peak value measured disturbance power value exceeds the quasi-peak value disturbance power limit value can be understood as that the electromagnetic capacity compatibility of the inductor 100 is unqualified. The mean measured disturbance power value not exceeding the mean disturbance power limit value can be interpreted as that the electromagnetic capacity compatibility of the inductor 100 is qualified, and the mean measured disturbance power value exceeding the mean disturbance power limit value can be interpreted as that the electromagnetic capacity compatibility of the inductor 100 is unqualified.

In fig. 3, for example, at a frequency of 30MHz, the peak measured disturbance power value is almost close to the quasi-peak disturbance power limit value, and the average measured disturbance power value is almost close to the average disturbance power limit value, so that at the frequency of 30MHz, the electromagnetic compatibility of the first inductor is poor, and even the first inductor is not qualified. Compared with fig. 3, under any frequency, the peak value measured disturbance power value in fig. 4 does not exceed or is not almost close to the quasi-peak value disturbance power limit value, and the average value measured disturbance power value does not exceed or is not almost close to the average value disturbance power limit value. Therefore, practice proves that the inductor 100 of the present invention has better electromagnetic compatibility.

Additionally, the utility model discloses a large amount of experiments have been carried out respectively with first inductor and second inductor to the utility model, have still obtained like the frequency-disturbance voltage curve graph of the inductor that fig. 5-6 are shown, and fig. 3 is the frequency-disturbance voltage curve graph of first inductor, and fig. 4 is the second inductor, also is the frequency-disturbance voltage curve graph of inductor 100 of the utility model.

In fig. 5, the abscissa is the frequency of the first inductor, the unit is MHz, the ordinate is the disturbance voltage of the first inductor, the linear C1 is the quasi-peak disturbance voltage limit, the linear C2 is the average disturbance voltage limit, the linear C3 is the peak measured disturbance voltage value, and the linear C4 is the average measured disturbance voltage value. The abscissa of fig. 6 is the frequency of the second inductor in MHz, the ordinate is the disturbance voltage of the second inductor, the line H1 is the quasi-peak disturbance voltage limit, the line H2 is the mean disturbance voltage limit, the line H3 is the peak measured disturbance voltage value, and the line H4 is the mean measured disturbance voltage value.

The fact that the peak measured disturbance voltage value does not exceed the quasi-peak disturbance voltage limit value can be understood as that the electromagnetic capacity compatibility of the inductor 100 is qualified, and the fact that the peak measured disturbance voltage value exceeds the quasi-peak disturbance voltage limit value can be understood as that the electromagnetic capacity compatibility of the inductor 100 is unqualified. The mean measured disturbance voltage value not exceeding the mean disturbance voltage limit value can be interpreted as a pass of the electromagnetic capability compatibility capability of the inductor 100, and the mean measured disturbance voltage value exceeding the mean disturbance voltage limit value can be interpreted as a fail of the electromagnetic capability compatibility capability of the inductor 100.

In fig. 5, for example, at a frequency of 30MHz, the peak measured disturbance voltage value has exceeded the quasi-peak disturbance voltage limit, and the average measured disturbance voltage value has also exceeded the average disturbance voltage limit, so that at a frequency of 30MHz, the electromagnetic compatibility capability of the first inductor is not qualified. Compared with fig. 5, under any frequency, the peak value measured disturbance voltage value in fig. 6 does not exceed the quasi-peak value disturbance voltage limit value all the time, and the average value measured disturbance voltage value does not exceed the average value disturbance voltage limit value all the time. Therefore, practice proves that the inductor 100 of the present invention has better electromagnetic compatibility.

In some embodiments of the present invention, referring to fig. 1-2, the spacing between the first pins 3 and the second pins 4 is not less than 5 mm. It can be understood that, since the inductor 100 is used in an air conditioner, the current is large, the voltage is high, a large voltage drop is generated between the input terminal and the output terminal during operation, and the first pin 3 and the second pin 4 are too close to each other to cause high-voltage discharge sparking, the distance between the first pin 3 and the second pin 4 is not less than 5mm, so that the high-voltage discharge sparking caused between the first pin 3 and the second pin 4 can be avoided.

According to some embodiments of the present invention, referring to fig. 1-2, the distance between the first pins 3 and the second pins 4 is 12-18 mm. Therefore, not only can high-voltage discharge ignition caused between the first pin 3 and the second pin 4 be avoided, but also the electromagnetic compatibility of the inductor 100 is better.

Preferably, the distance between the first pin 3 and the second pin 4 is 15.5mm, so that not only can the high-voltage discharge ignition caused between the first pin 3 and the second pin 4 be avoided, but also the electromagnetic compatibility of the inductor 100 is optimized.

According to some embodiments of the present invention, as shown in fig. 1-2, the inductor 100 may further include a supporting member 6, and the supporting member 6 is disposed on the second end surface 12 of the fixing base 1. It can be understood that, the ends of the first pins 3 and the second pins 4 protruding out of the second end face 12 of the fixing base 1 are both required to be connected with the circuit board, and only two pins may have unstable connection, and the supporting member 6 can be used to be connected with the circuit board, where the connection is a fixed connection and has no meaning of electrical connection. The connecting points of the fixing base 1 and the circuit board can be increased by the supporting piece 6, so that the connection between the fixing base 1 and the circuit board is more stable, and further the connection between the inductor 100 and the circuit board is more stable, in other words, the inductor 100 is not easy to fall off from the circuit board by arranging the supporting piece 6, and therefore the problems that the inductor 100 fails and the air conditioner cannot continue to work due to the fact that the inductor 100 falls off from the circuit board can be avoided.

In addition, in some specific examples, the circuit board may be fixed on a cabinet of an air conditioner, a direction from the first end surface 11 to the second end surface 12 of the fixing base 1 coincides with a height direction of the air conditioner, and the fixing base 1 is connected to the circuit board through the first pin 3, the second pin 4 and the supporting member 6, that is, the inductor 100 is installed horizontally, and therefore, the supporting member 6 makes the installation of the inductor 100 more balanced and stable.

In some embodiments of the present invention, as shown in fig. 1-2, the supporting member 6 may be a plurality of supporting members 6, and the plurality of supporting members 6 are symmetrically disposed with respect to the central point of the fixing base 1. Therefore, besides the first pin 3 and the second pin 4, the connection point of the fixing base 1 and the circuit board can also be provided with a plurality of supporting pieces 6, the connection points of the fixing base 1 and the circuit board can be further increased by the plurality of supporting pieces 6, the connection of the fixing base 1 and the circuit board is further stable, and further the connection of the inductor 100 and the circuit board is more stable, in other words, the inductor 100 is enabled to be less prone to fall off from the circuit board by the arrangement of the plurality of supporting pieces 6, so that the problems that the inductor 100 fails after the inductor 100 falls off from the circuit board and the air conditioner cannot continue to work can be avoided.

Additionally, the utility model discloses an inductor 100 can be for horizontal installation, and the central point central symmetry of the relative fixing base 1 of a plurality of support piece 6 sets up and makes inductor 100's installation more balanced, stable to be convenient for inductor 100's horizontal installation. The horizontal installation of the inductor 100 can save the installation space in the air conditioner, and compared with the vertical installation (the direction from the first end surface 11 to the second end surface 12 of the fixed seat 1 is vertical to the height direction of the air conditioner), the risk that the inductor 100 falls due to the heavy weight of the inductor 100 can be avoided.

Preferably, as shown in fig. 2, the number of the supporting members 6 may be four, and the four supporting members 6 are arranged in a central symmetry manner with respect to the center point of the fixing base 1.

According to some embodiments of the present invention, in conjunction with fig. 1-2, a first length of the first pin 3 extending out of the second end face 12, a second length of the second pin 4 extending out of the second end face 12, and a third length of the support member 6 extending out of the second end face 12 are the same. Thereby, the first pin 3, the second pin 4 and the support 6 can be easily connected to the circuit board at the same time.

In some embodiments of the present invention, as shown in fig. 1, the center of the fixing base 1 and the center of the magnetic member 2 are overlapped. Therefore, the center of gravity of the whole inductor 100 is stable, and the inductor 100 is not easy to fall off after being installed on the air conditioner. Moreover, the center of the fixing seat 1 and the center of the magnetic part 2 are overlapped, so that the arrangement of the first pin 3 and the second pin 4 is convenient, and the arrangement of the supporting part 6 is also convenient.

According to some embodiments of the present invention, as shown in fig. 1-2, the fixing base 1 is provided with a heat dissipation structure 13. The heat dissipation structure 13 may help the inductor 100 dissipate heat as the inductor 100 generates heat during operation.

In some specific examples, the heat dissipation structure 13 is a groove provided on the second end surface 12. Since the groove has more groove wall area than the plane where the groove is flush with the second end surface 12, the groove can increase the heat dissipation area of the fixing base 1, thereby facilitating the heat dissipation of the inductor 100. Further, the groove may be spaced apart plural, whereby the heat dissipation effect of the inductor 100 may be further enhanced.

In other specific examples, as shown in fig. 1-2, the heat dissipation structure 13 is a heat dissipation hole 131 penetrating through the fixing base 1 in the thickness direction of the fixing base 1, so as to facilitate heat dissipation of the inductor 100. Further, the heat dissipation hole 131 may be spaced apart, whereby the heat dissipation effect of the inductor 100 may be further enhanced.

According to some embodiments of the present invention, referring to fig. 2, the peripheral wall of the fixing base 1 includes two parallel surfaces 14 parallel to each other, and the line connecting the first pin 3 and the second pin 4 is parallel to the parallel surfaces 14. Therefore, after the two parallel surfaces 14 of the fixing base 1 are grabbed, the fixing base 1 can be conveniently connected with a circuit board, namely, the inductor 100 is conveniently mounted on the circuit board.

Thereby, the first pin 3, the second pin 4 and the support 6 can be easily connected to the circuit board at the same time.

As shown in fig. 1, the center of the fixing base 1 and the center of the magnetic member 2 are arranged to coincide with each other. Therefore, the center of gravity of the whole inductor 100 is stable, and the inductor 100 is not easy to fall off after being installed on the air conditioner. Moreover, the center of the fixing seat 1 and the center of the magnetic part 2 are overlapped, so that the arrangement of the first pin 3 and the second pin 4 is convenient, and the arrangement of the supporting part 6 is also convenient.

As shown in fig. 1-2, the fixing base 1 is provided with a heat dissipation structure 13. The heat dissipation structure 13 may help the inductor 100 dissipate heat as the inductor 100 generates heat during operation.

In some specific examples, as shown in fig. 1-2, the heat dissipation structure 13 is a heat dissipation hole 131 penetrating through the fixing base 1 in a thickness direction of the fixing base 1, so as to facilitate heat dissipation of the inductor 100. Further, the heat dissipation hole 131 may be spaced apart, whereby the heat dissipation effect of the inductor 100 may be further enhanced.
