[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0040] The electronic component 1, such as a multilayer chip inductor, generally includes a component body 10, a first terminal electrode 11, a second terminal electrode 12, and a coil conductor 13. The effective coil area enclosed by the coil conductor 13 affects the size of the inductance. In order to obtain a higher inductance in a multilayer chip inductor with a limited number of layers, the area enclosed by the coil conductor 13 is generally increased. Figure 1 As shown, the shape of the coil conductor 13 is generally rectangular, that is, the coil conductor 13 includes an upper conductor 130, a first side conductor 131, a lower conductor 133 and a second side conductor 135 which are connected end to end in sequence. However, when the area enclosed by the coil conductor 13 is increased, that is, when the length of each conductor is increased, the distance between the coil conductor 13 and the terminal electrode is reduced, resulting in an increase in parasitic capacitance, and the total length of the coil conductor 13 is also increased, so that the total resistance of the coil conductor 13 is increased, resulting in an increase in the heat loss of the coil conductor 13, thereby causing the quality factor of the multilayer chip inductor to be unable to be effectively improved.
[0041] The technical solution of the present invention will be further described below in conjunction with embodiments and drawings.
[0042] See also Figure 2In a first aspect of an embodiment of the present invention, an electronic component 1 is provided. The electronic component 1 includes a component body 10, a first terminal electrode 11, a second terminal electrode 12, and a coil conductor 13. The component body 10 is disposed on one side of the component body 10 in a first direction X, and the component body 10 is disposed on the other side of the component body 10 in the first direction X. The coil conductor 13 is disposed on the component body 10 and is electrically connected to the first terminal electrode 11 and the second terminal electrode 12. The coil conductor 13 includes an upper conductor 130, a first side conductor 131, a plurality of first oblique conductors 132, a lower conductor 133, a plurality of second oblique conductors 134, and a second side conductor 135. The upper conductor 130 and the lower conductor 131 are connected to each other. The side conductor 133 is extended along the first direction X, the first side conductor 131 and the second side conductor 135 are extended along the second direction Y, the first oblique conductor 132 is arranged corresponding to the first terminal electrode 11, the first oblique conductor 132 is inclined relative to the first side conductor 131 and the lower conductor 133, and an angle is formed between two adjacent first oblique conductors 132, the second oblique conductor 134 is arranged corresponding to the second terminal electrode 12, the second oblique conductor 134 is inclined relative to the second side conductor 135 and the lower conductor 133, and an angle is formed between two adjacent second oblique conductors 134, wherein the first direction X is perpendicular to the second direction Y.
[0043] In the electronic component 1 provided by the first aspect of the embodiment of the present invention, the component body 10 is used to carry the first terminal electrode 11, the second terminal electrode 12 and the coil conductor 13. The first terminal electrode 11 and the second terminal electrode 12 play the role of achieving physical conduction with the outside. The coil conductor 13 is used to enclose and form an inductor region. Since the circumference of a circle is the shortest under the same area, the portion of the coil conductor 13 corresponding to the first terminal electrode 11 is set as a plurality of first oblique conductors 132, and the portion of the coil conductor 13 corresponding to the second terminal electrode 12 is set as a plurality of second oblique conductors 134. When the number of the first oblique conductors 132 and the second oblique conductors is more, the shape enclosed by the plurality of first oblique conductors 132 and the plurality of second oblique conductors 134 is closer to a circle. When the area of the inductance region enclosed by the coil conductor 13 is kept constant or kept as constant as possible, that is, when the inductance of the coil conductor 13 is kept constant, compared with the rectangular coil conductor in the related art, and compared with the case where the number of the first oblique conductor 132 and the second oblique conductor is one, the total length of the coil conductor 13 can be reduced, thereby reducing the total resistance of the coil conductor 13, and thus improving the quality factor of the electronic component 1. At the same time, compared with the rectangular coil conductor in the related art, the distance between the multiple first oblique conductors 132 and the first terminal electrode 11 is farther, and the distance between the multiple second oblique conductors 134 and the second terminal electrode 12 is also farther, which can reduce the parasitic capacitance generated by the electronic component 1, thereby improving the self-resonance frequency of the electronic component 1.
[0044] Please also read Figure 3 and Figure 4 The component body 10 in the present application includes a plurality of insulating layers 100, and the plurality of insulating layers 100 are stacked along the thickness direction Z of the electronic component 1, and the thickness direction of the electronic component 1 is perpendicular to the first direction X and the second direction Y. The coil conductor 13 includes a plurality of electrode layers 13a and a plurality of conductive portions 13b, and each electrode layer 13a is respectively arranged between two insulating layers 100, and the conductive portion 13b penetrates the insulating layer 100 along the thickness direction and is connected to the electrode layers 13a on two opposite sides of the insulating layer 100 in the thickness direction Z. Among the plurality of electrode layers 13a, two electrode layers 13a located on two opposite sides in the thickness direction Z, one of which is electrically connected to the first terminal electrode 11, and the other is electrically connected to the second terminal electrode 12.
[0045] In this embodiment, since the electrode layer 13a is not a closed figure (otherwise the electrode layer 13a will be short-circuited), the coil conductor 13 has an upper conductor 130, a first side conductor 131, a plurality of first oblique conductors 132, a lower conductor 133, a plurality of second oblique conductors 134 and a second side conductor 135, which means that the projection of all electrode layers 13a along the thickness direction Z on the insulating layer 100 will form a shape as shown in FIG. Figure 2 The upper conductor 130, the first side conductor 131, the plurality of first oblique conductors 132, the lower conductor 133, the plurality of second oblique conductors 134 and the second side conductor 135 shown in the figure, each electrode layer 13a can be selected to be composed of any part of the complete pattern composed of the upper conductor 130, the first side conductor 131, the plurality of first oblique conductors 132, the lower conductor 133, the plurality of second oblique conductors 134 and the second side conductor 135. For example, an electrode layer 13a may include the upper conductor 130, the first side conductor 131, A plurality of first oblique conductors 132, a plurality of second oblique conductors 134 and a second side conductor 135, or an electrode layer 13a may include an upper conductor 130, a first side conductor 131, a first oblique conductor 132, a lower conductor 133, a plurality of second oblique conductors 134 and a second side conductor 135, or an electrode layer 13a may include an upper conductor 130, a first side conductor 131, half of a first oblique conductor 132, a lower conductor 133, a plurality of second oblique conductors 134 and a second side conductor 135.
[0046] In this application, the “upper” of the upper conductor 130 and the “lower” of the lower conductor 133 represent Figure 2 The second direction Y is the direction pointing to the up and down direction. The "side" of the first side conductor 131 and the second side conductor 135 in this application means Figure 2On the left or right in the paper plane direction, the first direction X is the direction pointing in the left-right direction. The above directions are all examples for facilitating the understanding of the shape of the coil conductor 13, and do not represent the actual directions of the components in the actual application of the electronic component 1.
[0047] Optionally, the number of the first bevel conductors 132 can be two, three, four, five, etc., and the number of the second bevel conductors 134 can be two, three, four, five, etc. The specific number can be selected according to the actual situation and is not specifically limited in this embodiment.
[0048] In some embodiments, the number of the first bevel conductors 132 is two (as shown in Figure 2 ), or three (as shown in Figure 5 ), and the number of the second bevel conductors 134 is two (as shown in Figure 2 ), or three (as shown in Figure 5 ).
[0049] By making the number of the first bevel conductors 132 and the second bevel conductors 134 be two or three, the shape enclosed by the multiple first bevel conductors 132 and the multiple second bevel conductors 134 is relatively close to a circle, which can better reduce the total resistance of the coil conductor 13. At the same time, the distance between the multiple first bevel conductors 132 and the first terminal electrode 11 is relatively far, and the distance between the multiple second bevel conductors 134 and the second terminal electrode 12 is also relatively far, which can balance the consideration of the quality factor and the self-resonant frequency of the electronic component 1, and can better improve both the quality factor and the self-resonant frequency of the electronic component 1.
[0050] Please refer to Figure 2 , in some embodiments, the included angle between two adjacent first bevel conductors 132 is a1, and the included angle a1 satisfies: 90° < a1 < 180°, and / or, the included angle between two adjacent second bevel conductors 134 is a2, and the included angle a2 satisfies: 90° < a2 < 180.
[0051] In one example, the included angle between two adjacent first bevel conductors 132 is a1, and the included angle a1 satisfies: 90° < a1 < 180°. By making the included angle between the first bevel conductors 132 be an obtuse angle and be the angle protruding towards the first terminal electrode 11, compared with the case where the included angle between the first bevel conductors 132 is an acute angle, the distance between the first bevel conductors 132 and the first terminal electrode 11 can be relatively far. At the same time, the area of the inductance region formed by enclosing the coil conductor 13 can also be relatively large, thereby improving the quality factor and the self-resonant frequency of the electronic component 1.
[0052] Exemplarily, the included angle a1 can be 100°, 110°, 120°, 130°, 140°, 150°, 160° or 170°.
[0053] In another example, the included angle between two adjacent second bevel conductors 134 is a2, and the included angle a2 satisfies: 90° < a2 < 180°. This makes the included angle between the second bevel conductors 134 an obtuse angle and an angle protruding towards the second terminal electrode 12. Compared with the case where the included angle between the second bevel conductors 134 is an acute angle, it can make the distance between the second bevel conductors 134 and the second terminal electrode 12 relatively far. At the same time, it can also make the area of the inductance region formed by the coil conductor 13 enclosed larger, thereby improving the quality factor and self-resonant frequency of the electronic component 1.
[0054] Exemplarily, the included angle a2 can be 100°, 110°, 120°, 130°, 140°, 150°, 160° or 170°.
[0055] In yet another example, the included angle between two adjacent first bevel conductors 132 is a1, and the included angle a1 satisfies: 90° < a1 < 180°, and the included angle between two adjacent second bevel conductors 134 is a2, and the included angle a2 satisfies: 90° < a2 < 180.
[0056] In this way, the included angle between the first bevel conductors 132 is an obtuse angle and an angle protruding towards the first terminal electrode 11, and at the same time, the included angle between the second bevel conductors 134 is an obtuse angle and an angle protruding towards the second terminal electrode 12, which can better improve the quality factor and self-resonant frequency of the electronic component 1.
[0057] Please refer to Figure 6 , in other embodiments, the included angle between two adjacent first bevel conductors 132 is a1, and the included angle a1 satisfies: a1 > 180°, and / or, the included angle between two adjacent second bevel conductors 134 is a2, and the included angle a2 satisfies: a2 > 180°. That is, the case where the included angle between the first bevel conductors 132 is an angle concave relative to the first terminal electrode 11, and the case where the included angle between the second bevel conductors 134 is an angle concave relative to the second terminal electrode 12. It can make the first bevel conductors 132 away from the first terminal electrode 11, and make the second bevel conductors 134 away from the second terminal electrode 12, greatly reducing the parasitic capacitance generated by the electronic component 1, thereby improving the self-resonant frequency of the electronic component 1.
[0058] In some embodiments, when the number of the first bevel conductors 132 is two or three, the included angle a1 satisfies: 120° ≤ a1, and / or, a1 ≤ 150°.
[0059] In one example, the angle a1 satisfies: 120°≤a1. In this way, the angle a1 can be made larger, so that the first oblique conductor 132 and the first terminal electrode 11 have a larger distance, which can effectively reduce the parasitic capacitance generated by the electronic component 1, thereby effectively improving the self-resonance frequency of the electronic component 1.
[0060] In another example, the angle a1 satisfies: a1≤150°. In this way, the angle a1 will not be too large, so that the coil conductor 13 can enclose a larger inductor region.
[0061] In another example, the angle a1 satisfies: 120°≤a1≤150°. For example, the angle a1 may be 120°, 130°, 140° or 150°.
[0062] In this way, on the one hand, the angle of a1 can be made larger, so that the first oblique conductor 132 has a larger distance from the first terminal electrode 11, which can better reduce the parasitic capacitance generated by the electronic component 1, thereby better improving the self-resonant frequency of the electronic component 1. On the other hand, the angle of a1 can be made not too large, so that the coil conductor 13 can enclose a larger inductance area. In addition, when the number of the first oblique conductors 132 is two or three, the shape formed by the multiple first oblique conductors 132 can be made closer to a 1 / 4 circle, which can better reduce the total length of the coil conductor 13, thereby better reducing the total resistance of the coil conductor 13, and further better improving the quality factor of the electronic component 1.
[0063] In some embodiments, when the number of the second oblique-side conductors 134 is two or three, the angle a2 satisfies: 120°≤a2, and / or a2≤150°.
[0064] In one example, the angle a2 satisfies: 120°≤a2. In this way, the angle a2 can be made larger, so that the second oblique conductor 134 and the second terminal electrode 12 have a larger distance, which can effectively reduce the parasitic capacitance generated by the electronic component 1, thereby effectively improving the self-resonance frequency of the electronic component 1.
[0065] In another example, the angle a2 satisfies: a2≤150°. In this way, the angle a2 will not be too large, so that the coil conductor 13 can enclose a larger inductor region.
[0066] In another example, the angle a2 satisfies: 120°≤a2≤150°. For example, the angle a2 may be 120°, 130°, 140° or 150°.
[0067] In this way, on the one hand, the angle of a2 can be made larger, so that the second oblique conductor 134 has a larger distance from the second terminal electrode 12, which can better reduce the parasitic capacitance generated by the electronic component 1, thereby better improving the self-resonant frequency of the electronic component 1. On the other hand, the angle of a2 can be made not too large, so that the coil conductor 13 can enclose a larger inductance area. In addition, when the number of the second oblique conductors 134 is two or three, the shape formed by the multiple second oblique conductors 134 can be closer to a 1 / 4 circle, which can better reduce the total length of the coil conductor 13, thereby better reducing the total resistance of the coil conductor 13, and further better improving the quality factor of the electronic component 1.
[0068] In some embodiments, the first terminal electrode 11 includes a first portion 110 and a second portion 111 connected to each other, the first portion 110 extends along a first direction X, and the second portion 111 extends along a second direction Y; the second terminal electrode 12 includes a third portion 120 and a fourth portion 121 connected to each other, the third portion 120 extends along the first direction X, and the fourth portion 121 extends along the second direction Y. In this way, the first terminal electrode 11 and the second terminal electrode 12 are L-shaped, which can facilitate the first terminal electrode 11 and the second terminal electrode 12 to achieve physical conduction with the outside.
[0069] In some embodiments, in the first direction X, the bottom conductor 133 is located between the first portion 110 and the third portion 120 , and / or in the second direction Y, the first side conductor 131 is located above the second portion 111 , and the second side conductor 135 is located above the fourth portion 121 .
[0070] In one example, in the first direction X, the lower conductor 133 is located between the first portion 110 and the third portion 120 . That is, in the first direction X, the length d1 of the lower conductor 133 is smaller than the distance d2 between the first portion 110 and the third portion 120 .
[0071] In this way, the distance between the first oblique conductor 132 connected to the lower conductor 133 and the first part 110 of the first terminal electrode 11 can be increased, and the distance between the second oblique conductor 134 connected to the lower conductor 133 and the third part 120 of the second terminal electrode 12 in the first direction X can be increased, thereby reducing the parasitic capacitance generated by the electronic component 1.
[0072] In another example, in the second direction Y, the first side conductor 131 is located above the second portion 111, and the second side conductor 135 is located above the fourth portion 121. That is, in the second direction Y, the connection between the first side conductor 131 and the first oblique conductor 132 is located above the second portion 111, and the connection between the second side conductor 135 and the second oblique conductor 134 is located above the fourth portion 121.
[0073] In this way, the distance between the first oblique conductor 132 connected to the first side conductor 131 and the second part 111 of the first terminal electrode 11 in the second direction Y can be increased, and the distance between the second oblique conductor 134 connected to the second side conductor 135 and the fourth part 121 of the second terminal electrode 12 can be increased, thereby reducing the parasitic capacitance generated by the electronic component 1.
[0074] In another example, in the first direction X, the lower conductor 133 is located between the first portion 110 and the third portion 120 , and in the second direction Y, the first side conductor 131 is located above the second portion 111 , and the second side conductor 135 is located above the fourth portion 121 .

Exemplarily, the distance L6 may be 45 μm, 55 μm, 65 μm or 75 μm.
[0117] On the one hand, the parasitic capacitance generated by the second bevel conductor 134 and the third part 120 and the fourth part 121 can be reduced, thereby increasing the self-resonance frequency of the electronic component 1.

In this way, the coil conductor 13 can be symmetrically arranged along the first direction X, so that the processing technology of the coil conductor 13 is relatively simple, and at the same time, the performance of the electronic component 1 can be relatively uniform.
