Description

Technical Field

[0001] The present disclosure relates to an electronic component having a case capable of accommodating chip components.

Background Art

[0002] As an electronic component having a case capable of accommodating chip components, for example, there is an electronic component described in Patent Document 1. In the electronic component described in Patent Document 1, a metal terminal connected to the terminal electrode of the chip component is attached to the case.

[0003] The metal terminal has an inner electrode portion that contacts the terminal electrode of the chip component. A part of the inner electrode portion is curved toward the terminal electrode and is in local contact with the terminal electrode. The inner electrode portion is fixed to the terminal electrode by its elasticity without using solder. However, according to the investigation by the present inventors, it has been clarified that there is a possibility that the contact between the inner electrode portion and the terminal electrode becomes insufficient during the reflow of the electronic component.

Summary of the Invention

Problems to be Solved by the Invention

[0005] In view of such a situation, the present disclosure has been made, and its object is to provide an electronic component capable of preventing the occurrence of poor contact.

Means for Solving the Problems

[0006] The inventors have discovered the following facts as a result of their research. The inside of the case is filled with potting resin to ensure, for example, moisture resistance or shock resistance of chip components. However, during the reflow process of electronic components, for example, the expansion of the potting resin can cause misalignment of the contact between the inner electrode and the terminal electrode, potentially leading to poor contact between the inner electrode and the terminal electrode. Therefore, the inventors have diligently investigated and found a technique to prevent such problems from occurring.

[0007] To achieve the above objectives, the electronic components of this disclosure are: A chip component having terminal electrodes, A case having a housing recess for housing the aforementioned chip component, The resin that fills the inside of the aforementioned recessed area, The case has conductive terminals that are attached to the case, The conductive terminal is disposed inside the housing recess and has an inner electrode portion connected to the terminal electrode, The inner electrode portion has a space-forming portion that forms a space for filling with conductive material between itself and the outer surface of the chip component, at a position closer to the bottom surface than the opening of the housing recess.

[0008] In the electronic component of this disclosure, when the terminal electrodes of the chip component are connected to the inner electrode portion, a filling space is formed between the outer surface of the chip component and the space-forming portion. By filling this filling space with a conductive agent, the terminal electrodes and the space-forming portion can be connected via the conductive agent. This prevents misalignment of the contact points between the inner electrode portion and the terminal electrodes due to resin expansion, and avoids contact failure between them.

[0009] Furthermore, since the filling space is formed closer to the bottom surface than the opening of the housing recess, the conductive material filling the filling space is covered by the resin filling the inside of the housing recess. This prevents the conductive material from being exposed to the outside space, improving the moisture resistance of the conductive material and, consequently, the reliability of the electronic component.

[0010] The space-forming portion and the terminal electrode may be connected via a conductive material filled in the aforementioned space. In this case, as described above, since the space-forming portion and the terminal electrode are physically connected, poor contact between the inner electrode portion and the terminal electrode due to resin expansion can be prevented.

[0011] The space-forming portion may protrude in a direction away from the outer surface of the chip component. In this case, the distance between the terminal electrode and the space-forming portion increases, and the volume of the filled space can be increased. This increases the volume of conductive material filled in the filled space, thereby increasing the connection strength between the space-forming portion and the terminal electrode.

[0012] The side surface of the chip component faces the bottom surface of the housing recess, and the space-forming portion may be located around the corner where the end surface of the chip component and the side surface intersect. In this case, the space-forming portion is positioned closer to the bottom surface than the opening of the housing recess. Therefore, the filling space is also formed closer to the bottom surface than the opening of the housing recess. This allows the conductive agent filled in the filling space to be covered with resin so that it is not exposed to the outside space.

[0013] The space-forming portion forms the filling space between itself and each of the end face and side surface, and may be bent to surround the corner. In this case, the filling space is surrounded by the space-forming portion and the end face and side surface of the chip component. As a result, leakage of the conductive agent from the filling space is reduced, and the volume of conductive agent filled into the filling space can be increased.

[0014] The inner electrode portion is continuous with the space-forming portion and has an end-face-facing portion that is spaced apart from the end face of the chip component. The distance between the space-forming portion and the end face of the chip component may be greater than the distance between the end-face-facing portion and the end face of the chip component. In this case, the volume of the filling space can be increased, and the volume of conductive material filled in the filling space can be increased.

[0015] The inner electrode portion has a bent portion that bends toward the end face of the chip component, and the space forming portion may be integrally formed with the bent portion. By forming a bent portion in the inner electrode portion, the inner electrode portion is given elasticity, and this elasticity allows the inner electrode portion to be fixed to the terminal electrode.

[0016] The width of the space-forming portion may be smaller than the width of the terminal electrode. In this case, the volume of the filled space can be adjusted according to the width of the space-forming portion. Therefore, the space-forming portion and the terminal electrode can be connected via the conductive material while adjusting the amount of conductive material filled into the filled space.

[0017] The inner electrode portion has a plurality of inner electrode portions, and the space-forming portion has a plurality of space-forming portions formed in the plurality of inner electrode portions, and the plurality of inner electrode portions may be spaced apart from each other. In this case, a conductive material can be filled into the plurality of filling spaces formed at the positions of the plurality of space-forming portions. Therefore, the plurality of space-forming portions are connected to the terminal electrode at multiple positions via the conductive material. This can improve the connection reliability between the conductive terminal and the terminal electrode.

[0018] The outer surface of the case may have a pair of connecting protrusions projecting outward from the outer surface of the case, and connecting recesses recessing inward from the outer surface of the case. In this case, when an electronic component is provided with multiple (for example, two) cases, the multiple cases can be connected by engaging the connecting protrusions of one case with the connecting recesses of the other case.

MODE FOR CARRYING OUT THE INVENTION

[0020] Embodiments of the present disclosure will be described with reference to the drawings. Although the description will be made with reference to the drawings as necessary, the illustrated content is only schematically and exemplarily shown for the understanding of the present disclosure, and the appearance and dimensional ratios may be different from the actual ones. Further, although specifically described below with reference to the embodiments, the present disclosure is not limited to these embodiments. [[ID=4-2]]

[0021] First Embodiment As shown in FIGS. 1A and 1B, the electronic component 1 of the first embodiment includes capacitor chips 10a and 10b, a case 20, a resin 30 (FIG. 2), individual conductive terminals 40a and 40b, and a common conductive terminal 50.

[0022] In the diagram, the XYZ coordinate system is a coordinate system based on Case 20. When Case 20 is viewed from above, the axis parallel to one of the two orthogonal sides of Case 20 is the X-axis, and the axis parallel to the other side is the Y-axis. The Z-axis is perpendicular to the base of Case 20. The origin of the XYZ coordinate system is set to the center of the base of Case 20.

[0023] For each of the X, Y, and Z axes, the side in the positive direction from the origin is sometimes called "one side," and the side in the negative direction from the origin is sometimes called "the other side." In particular, one side of the Z axis is called "up," and the other side of the Z axis is called "down." Also, the direction toward the center of Case 20 is called "inside," and the direction away from the center of Case 20 is called "outside."

[0024] Capacitor chips 10a and 10b each have a substantially rectangular parallelepiped shape and are identical in shape and size to each other. In this embodiment, "identical" does not mean completely identical, but also allows for variations of ± a few percent. To avoid redundant descriptions, the configuration common to capacitor chips 10a and 10b will only be described for capacitor chip 10a below.

[0025] The outer surface of the capacitor chip 10a has multiple (six in this embodiment) surfaces. Of these surfaces, two surfaces located opposite each other along the X-axis are the end faces 13 and 14 (Figure 2). The remaining four surfaces are the side faces 15.

[0026] As shown in Figure 2, the capacitor chip 10a has a plurality of internal electrode layers 16 and a plurality of dielectric layers 17. The plurality of internal electrode layers 16 and the plurality of dielectric layers 17 are stacked along the Y-axis. Terminal electrodes 11 and 12 are formed on the end faces 13 and 14, respectively. The plurality of internal electrode layers 16 are connected to the terminal electrodes 11 or 12. A portion of the terminal electrode 11 wraps around to the side surface 15. Similarly, a portion of the terminal electrode 12 wraps around to the side surface 15.

[0027] The shape and size of the capacitor chip 10a are not particularly limited. The X-axis dimension of the capacitor chip 10a is, for example, 1.0 to 6.5 mm, the Y-axis dimension is, for example, 0.3 to 5.5 mm, and the Z-axis dimension is, for example, 0.3 to 5.5 mm.

[0028] As shown in Figure 3, the case 20 has a housing recess 22 for housing the capacitor chips 10a and 10b. The case 20 may also have a wall 21, a bottom surface 23, an opening edge surface 24, a partition portion 25, connecting protrusions 26a and 26b, and connecting recesses 27a and 27b. The case 20 is made of an insulator such as ceramic, glass, or synthetic resin.

[0029] The bottom surface 23 constitutes the bottom of the case 20. At least one side surface 15 of the capacitor chip 10a is positioned on the bottom surface 23 so as to face it. Also, at least one side surface 15 of the capacitor chip 10b is positioned on the bottom surface 23 so as to face it.

[0030] The wall 21 is cylindrical and formed along the outer edge of the bottom surface 23. The wall 21 rises perpendicularly to the bottom surface 23 from the outer edge of the bottom surface 23. The wall 21 has an outer surface 21a and an inner surface 21b located on the opposite side of the outer surface 21a. In this embodiment, perpendicular means allowing an error of ±10 degrees. Similarly, parallel means allowing an error of ±10 degrees.

[0031] The outer surface 21a has a first surface 20a, a second surface 20b, a third surface 20c, and a fourth surface 20d. The first surface 20a and the third surface 20c are located on opposite sides along the X-axis, and the second surface 20b and the fourth surface 20d are located on opposite sides along the Y-axis.

[0032] The housing recess 22 is a space enclosed by the inner surface 21b and opens upward. The housing recess 22 has a housing space 22a for housing the capacitor chip 10a and a housing space 22b for housing the capacitor chip 10b. The height of the housing space 22a may be greater than the length of the capacitor chip 10a along the Z axis, and the height of the housing space 22b may be greater than the length of the capacitor chip 10b along the Z axis.

[0033] By housing the capacitor chips 10a and 10b in the housing spaces 22a and 22b, respectively, the capacitor chips 10a and 10b can be effectively protected from impacts and the like. The inside of the housing recess 22 is filled with resin 30 (Figure 2). The resin 30 is an insulating resin, such as a thermosetting resin like an epoxy resin or a phenolic resin.

[0034] By resin-encapsulating the capacitor chips 10a and 10b with resin 30, the moisture resistance, vibration resistance, shock resistance, dust resistance, and heat dissipation properties of the electronic component 1 can be improved.

[0035] The opening edge surface 24 is the upper end surface of the wall 21. The opening edge surface 24 is formed in a square ring shape along the opening edge of the receiving recess 22. Stepped portions 240 are formed on the positive Y-axis side and the negative X-axis side of the opening edge surface 24. The stepped portions 240 extend in an L-shape outside the opening edge surface 24. The stepped portions 240 are located below the opening edge surface 24.

[0036] The partition 25 is formed inside the accommodating recess 22. The partition 25 rises perpendicularly to the bottom surface 23 from the center of the X-axis of the bottom surface 23 and extends along the Y-axis. The partition 25 separates the accommodating space 22a from the accommodating space 22b.

[0037] Communication grooves 25a and 25b are formed at the upper end of the partition portion 25. Communication groove 25a is formed at the end of the partition portion 25 on the positive Y-axis side, and communication groove 25b is formed at the end of the partition portion 25 on the negative Y-axis side. The storage space 22a and the storage space 22b are in communication with each other via communication grooves 25a and 25b.

[0038] As shown in Figures 1A and 1B, a pair of connecting protrusions 26a are formed on the first surface 20a of the outer surface 21a, and a pair of connecting protrusions 26b are formed on the second surface 20b. In addition, a connecting recess 27a is formed on the third surface 20c of the outer surface 21a, and a connecting recess 27b is formed on the fourth surface 20d.

[0039] The connecting projection 26a has a columnar shape and protrudes away from the first surface 20a. The connecting projection 26a extends along the Z-axis from the lower end of the first surface 20a to near the center. In a plan view, the pair of connecting projections 26a extend diagonally with respect to the Y-axis. The distance between the pair of connecting projections 26a along the X-axis increases towards the positive Y-axis direction. The XY cross-sectional shape of the connecting projection 26a is a parallelogram, and the XZ cross-sectional shape of the connecting projection 26a is a rectangle, but the shape of the connecting projection 26a is not limited to these.

[0040] The connecting projection 26b has a columnar shape and protrudes away from the second surface 20b. The connecting projection 26b extends along the Z-axis from the lower end of the second surface 20b to near the center. In a plan view, the pair of connecting projections 26b extend obliquely with respect to the X-axis. The distance between the pair of connecting projections 26b along the Y-axis increases towards the positive X-axis direction. The XY cross-sectional shape of the connecting projection 26b is a parallelogram, and the YZ cross-sectional shape of the connecting projection 26b is a rectangle, but the shape of the connecting projection 26b is not limited to these.

[0041] The connecting recess 27a is recessed toward the inside of the wall 21 (towards the positive Y-axis direction). The connecting recess 27a extends along the Z-axis from the lower end of the third surface 20c to near the center. The width of the connecting recess 27a along the X-axis increases as it moves toward the inside of the wall 21.

[0042] The connecting recess 27b is recessed toward the inside of the wall 21 (towards the positive X-axis direction). The connecting recess 27b extends along the Z-axis from the lower end of the fourth surface 20d to near the center. The width of the connecting recess 27b along the Y-axis increases as it moves toward the inside of the wall 21.

[0043] As shown in Figure 4, in this embodiment, adjacent cases 20 can be connected along the Y-axis by engaging a pair of connecting protrusions 26a of one case 20 with a connecting recess 27a of the other case 20. More specifically, they can be engaged by inserting (sliding) the upper ends of the pair of connecting protrusions 26a of the other case 20 into the lower end of the connecting recess 27a of the one case 20.

[0044] Furthermore, adjacent cases 20 along the X-axis can be connected by engaging the pair of connecting protrusions 26b of one case 20 with the connecting recess 27b of the other case 20. More specifically, they can be engaged by inserting (sliding) the upper end of the pair of connecting protrusions 26b of the other case 20 into the lower end of the connecting recess 27b of the one case 20.

[0045] As shown in Figure 6, the individual conductive terminals 40a and 40b are mounted on the case 20. The individual conductive terminal 40a is electrically connected to the terminal electrode 12 of the capacitor chip 10a, and the individual conductive terminal 40b is electrically connected to the terminal electrode 12 of the capacitor chip 10b.

[0046] As shown in Figure 5, the individual conductive terminals 40a and 40b have the same shape, but their shapes may be different. In the following, to avoid redundant descriptions, the configuration common to both the individual conductive terminals 40a and 40b will only be described for the individual conductive terminal 40a.

[0047] The individual conductive terminals 40a are formed from a conductive material such as metal. Examples of metals that make up the individual conductive terminals 40a include iron, nickel, copper, silver, or alloys containing these materials. A metal coating may be formed on the surface of the individual conductive terminals 40a by plating, for example, using Ni, Sn, Cu, etc.

[0048] The width of the individual conductive terminals 40a along the Y-axis is approximately the same as the width of the capacitor chip 10a (Figure 1A) along the Y-axis, but may be different. The thickness of the individual conductive terminals 40a is, for example, 0.01 to 2.0 mm.

[0049] Each individual conductive terminal 40a has an inner electrode portion 41. Each individual conductive terminal 40a may also have an opening edge electrode portion 42 and a side electrode portion 43. As shown in Figure 6, the side electrode portion 43 faces the outer surface 21a of the wall 21. The side electrode portion 43 is spaced apart from the outer surface 21a along the X-axis, but may be in contact with the outer surface 21a.

[0050] The opening edge electrode portion 42 is continuous with the side electrode portion 43 and extends in a direction perpendicular to the side electrode portion 43. The opening edge electrode portion 42 faces the opening edge surface 24 of the wall 21. The opening edge electrode portion 42 is in contact with the opening edge surface 24, but may be spaced apart from the opening edge surface 24.

[0051] As shown in Figure 5, the inner electrode portion 41 has a space-forming portion 410. The inner electrode portion 41 may also have an end-face opposing portion 411 and a side support portion 412. As shown in Figure 6, the inner electrode portion 41 is positioned inside the housing recess 22 and is electrically connected to the terminal electrode 12 of the capacitor chip 10a.

[0052] The end face opposing portion 411 is continuous with the opening edge electrode portion 42 and extends in a direction perpendicular to the opening edge electrode portion 42. The end face opposing portion 411 is spaced apart from the inner surface 21b along the X-axis, but may be in contact with the inner surface 21b. The end face opposing portion 411 is arranged parallel to the inner surface 21b of the wall 21, but may be inclined with respect to the inner surface 21b.

[0053] The end face opposing portion 411 is positioned at a distance D2 from the end face 14 of the capacitor chip 10a. Therefore, a gap 80 is formed between the end face opposing portion 411 and the end face 14. However, the end face opposing portion 411 may be in contact with the end face 14 (terminal electrode 12). Also, the gap 80 may be filled with resin 30 (Figure 2). The end face opposing portion 411 is positioned parallel to the end face 14, but it may be inclined with respect to the end face 14.

[0054] The side support portion 412 abuts against at least one surface of the side surface 15 of the capacitor chip 10a, thereby supporting the capacitor chip 10a. Hereinafter, of the four surfaces forming the side surface 15, the surface that the side support portion 412 abuts against will be referred to as the "terminal fixing surface." The terminal fixing surface 150 is the surface facing the bottom surface 23 of the case 20.

[0055] The side support portion 412 is positioned parallel to the terminal fixing surface 150 and is in overall contact with the terminal fixing surface 150. The shape of the side support portion 412 is not limited to the shape shown in Figure 6, and a part of the side support portion 412 may be inclined with respect to the terminal fixing surface 150. The side support portion 412 may be in local contact with the terminal fixing surface 150.

[0056] The space-forming portion 410 is located between the end-face opposing portion 411 and the side support portion 412, and is continuous with them. The space-forming portion 410 is positioned closer to the bottom surface 23 than the opening of the housing recess 22. The space-forming portion 410 is bent (curved) in a substantially C-shape or substantially semi-circular shape and bulges (projects) away from the outer surface (end face 14 and terminal fixing surface 150) of the capacitor chip 10a. A portion of the space-forming portion 410 protrudes further in the positive X-axis direction than the end-face opposing portion 411. Another portion of the space-forming portion 410 protrudes further in the negative Z-axis direction than the side support portion 412.

[0057] The first end 410x of the space-forming portion 410 is located above the terminal fixing surface 150 of the capacitor chip 10a. The first end 410x is the position where the space-forming portion 410 begins to tilt with respect to the end face opposing portion 411. Above the terminal fixing surface 150, the space-forming portion 410 begins to bend in a direction away from the end face 14 of the capacitor chip 10a (towards the positive X-axis direction).

[0058] The second end 410y of the space-forming portion 410 is located below the terminal fixing surface 150 of the capacitor chip 10a. The second end 410y is the position where the space-forming portion 410 begins to tilt relative to the side support portion 412. The second end 410y is also the position where the space-forming portion 410 contacts the terminal fixing surface 150. Below the terminal fixing surface 150, the space-forming portion 410 begins to bend in a direction away from the terminal fixing surface 150 (negative Z-axis direction).

[0059] The space-forming portion 410 may be positioned around the corner 18 of the capacitor chip 10a where the end face 14 and the terminal fixing surface 150 intersect. The space-forming portion 410 may be bent to surround the corner 18. The space-forming portion 410 is smoothly curved, but its shape is not limited thereto. For example, the space-forming portion 410 may be bent discontinuously. Also, the space-forming portion 410 may be bent multiple times.

[0060] The space-forming portion 410 is located at the corner of the receiving recess 22 where the bottom surface 23 and the inner surface 21b of the wall 21 intersect. A portion of the space-forming portion 410 may also be in contact with the inner surface 21b. Another portion of the space-forming portion 410 may be in contact with the bottom surface 23.

[0061] The space-forming portion 410 forms a filling space 60 between itself and the outer surface of the capacitor chip 10a. The filling space 60 is the space sandwiched between the outer surface of the capacitor chip 10a and the space-forming portion 410. The filling space 60 is filled with a conductive material 70, which is made of solder, conductive adhesive, or the like. The filling space 60 may also be formed along the perimeter of the corner portion 18 of the capacitor chip 10a.

[0062] The filling space 60 is formed continuously with the gap 80. The distance (maximum distance) D1 between the corner portion 18 of the capacitor chip 10a and the space forming portion 410 may be greater than the distance D2 along the X axis between the end face 14 and the end face opposing portion 411. Also, the distance along the X axis between the end face 14 of the capacitor chip 10a and the space forming portion 410 may be greater than the distance D2 along the X axis between the end face 14 and the end face opposing portion 411. Furthermore, the distance along the Z axis between the terminal fixing surface 150 of the capacitor chip 10a and the space forming portion 410 may be greater than the distance D2 along the X axis between the end face 14 and the end face opposing portion 411.

[0063] The space-forming portion 410 forms a filling space 60 between itself and the end face 14, and also forms a filling space 60 between itself and the terminal fixing surface 150. Therefore, the conductive material 70 is filled between the end face 14 and the space-forming portion 410, and between the terminal fixing surface 150 and the space-forming portion 410. The space-forming portion 410 and the terminal electrode 12 are physically and electrically connected via the conductive material 70 filled in the filling spaces 60.

[0064] In the example shown in Figure 6, the filling space 60 is not completely filled with the conductive agent 70, but it may be completely filled with the conductive agent 70. Also, the conductive agent 70 may penetrate into the interior of the gap 80.

[0065] The common conductive terminal 50 is attached to the case 20. As shown in Figure 1A, the common conductive terminal 50 is electrically connected to the terminal electrode 11 of capacitor chip 10a and the terminal electrode 11 of capacitor chip 10b. The common conductive terminal 50 is made of the same material as the individual conductive terminals 40a.

[0066] As shown in Figure 5, the common conductive terminal 50 has inner electrode portions 51a and 51b. The common conductive terminal 50 may also have an opening edge electrode portion 52, a side electrode portion 53, and a connecting portion 54. As shown in Figure 6, the side electrode portion 53 is positioned on the stepped portion 240 and faces the outer surface 21a of the wall 21. The side electrode portion 53 is positioned spaced apart from the outer surface 21a along the X-axis, but may be in contact with the outer surface 21a.

[0067] The opening edge electrode portion 52 is continuous with the side electrode portion 53 and extends in a direction perpendicular to the side electrode portion 53. The opening edge electrode portion 52 faces the opening edge surface 24 of the wall 21. The opening edge electrode portion 52 is in contact with the opening edge surface 24, but may be spaced apart from the opening edge surface 24.

[0068] The connecting portion 54 is continuous with the opening edge electrode portion 52 and extends in a direction perpendicular to the side electrode portion 53. The connecting portion 54 is positioned spaced apart from the inner surface 21b of the wall 21 along the X-axis, but may be in contact with the inner surface 21b. The connecting portion 54 is positioned parallel to the inner surface 21b, but may be inclined with respect to the inner surface 21b. As shown in Figure 5, the connecting portion 54 has the role of connecting the inner electrode portion 51a and the inner electrode portion 51b along the Y-axis. The connecting portion 54 is positioned in the communication groove 25a (Figure 3) of the case 20.

[0069] The inner electrode portion 51a has a space-forming portion 510. The inner electrode portion 51a may also have an end-face opposing portion 511 and a side support portion 512. The inner electrode portion 51b has a space-forming portion 510. The inner electrode portion 51b may also have an end-face opposing portion 511 and a side support portion 512.

[0070] As shown in Figure 6, the inner electrode portion 51a is positioned inside the housing recess 22 and is electrically connected to the terminal electrode 11 of the capacitor chip 10a. The inner electrode portion 51b is positioned inside the housing recess 22 and is electrically connected to the terminal electrode 11 of the capacitor chip 10b.

[0071] The inner electrode portions 51a and 51b have the same shape, but their shapes may differ. In the following, to avoid redundant descriptions, the configuration common to both inner electrode portions 51a and 51b will only be described for inner electrode portion 51a. Furthermore, the configuration of inner electrode portion 51a is the same as that of inner electrode portion 41, except for the points described below. Therefore, to avoid redundant descriptions, the configuration of inner electrode portion 51a that is common to inner electrode portion 41 will not be described.

[0072] The end face opposing portion 511 is continuous with the connecting portion 54 and extends parallel to the connecting portion 54. The end face opposing portion 511 may be inclined with respect to the connecting portion 54. The end face opposing portion 511 is positioned at a distance D3 from the end face 13 of the capacitor chip 10a. Therefore, a gap 80 is formed between the end face opposing portion 511 and the end face 13. The distance D3 is the same as the distance D2, but may be different.

[0073] The space-forming portion 510 bulges (protrudes) in a direction away from the outer surface (end face 13 and terminal fixing surface 150) of the capacitor chip 10a. A portion of the space-forming portion 510 protrudes in the negative X-axis direction beyond the end face opposing portion 511. Another portion of the space-forming portion 510 protrudes in the negative Z-axis direction beyond the side support portion 512.

[0074] The first end 510x of the space-forming portion 510 is located above the terminal fixing surface 150 of the capacitor chip 10a. The first end 510x is the position where the space-forming portion 510 begins to tilt with respect to the end face opposing portion 511. Above the terminal fixing surface 150, the space-forming portion 510 begins to bend in a direction away from the end face 13 of the capacitor chip 10a (negative X-axis direction).

[0075] The second end 510y of the space-forming portion 510 is located below the terminal fixing surface 150 of the capacitor chip 10a. The second end 510y is the position where the space-forming portion 510 begins to tilt relative to the side support portion 512. The second end 510y is also the position where the space-forming portion 510 contacts the terminal fixing surface 150. Below the terminal fixing surface 150, the space-forming portion 510 begins to bend in a direction away from the terminal fixing surface 150 (negative Z-axis direction).

[0076] Electronic component 1 can be manufactured as follows. First, a case 20 as shown in Figure 3 is prepared, and individual conductive terminals 40a and 40b and a common conductive terminal 50 are attached to the case 20 as shown in Figure 6. Next, a capacitor chip 10a is housed in the housing space 22a, and a capacitor chip 10b is housed in the housing space 22b. Next, using a device such as a dispenser, conductive material 70 is filled into the filling space 60 formed at the position of the space forming portion 410 of the individual conductive terminal 40a. Similarly, conductive material 70 is filled into the filling space 60 formed at the position of the space forming portion 410 of the individual conductive terminal 40b. Furthermore, conductive material 70 is filled into the filling space 60 formed at the respective positions of the inner electrode portions 51a and 51b of the common conductive terminal 50. Next, resin 30 (Figure 2) is filled into the housing recess 22 so that the conductive material 70 is covered. The amount of resin 30 to be filled is not particularly limited, but for example, the resin 30 may be filled into the housing recess 22 until the capacitor chips 10a and 10b are covered with resin 30. In this way, the electronic component 1 can be manufactured.

[0077] Furthermore, before attaching the individual conductive terminals 40a and 40b and the common conductive terminal 50 to the case 20, the individual conductive terminals 40a and 40b and the common conductive terminal 50 may be attached to the capacitor chips 10a and 10b in advance. Also, before housing the capacitor chips 10a and 10b in the housing spaces 22a and 22b, the resin 30 may be filled into the housing recesses 22.

[0078] Specifically, individual conductive terminals 40a are attached to the terminal electrodes 12 of the capacitor chip 10a shown in Figure 6, and conductive material 70 is filled into the filling spaces 60 formed at the positions of the space-forming portions 410 of the individual conductive terminals 40a. In addition, individual conductive terminals 40b are attached to the terminal electrodes 12 of the capacitor chip 10b, and conductive material 70 is filled into the filling spaces 60 formed at the positions of the space-forming portions 410 of the individual conductive terminals 40b. Furthermore, common conductive terminals 50 are attached to the terminal electrodes 11 of capacitor chips 10a and 10b, and conductive material 70 is filled into the filling spaces 60 formed at the respective positions of the inner electrode portions 51a and 51b.

[0079] This allows for the formation of an assembly consisting of capacitor chips 10a and 10b, individual conductive terminals 40a and 40b, and a common conductive terminal 50. Next, resin 30 is filled into the housing recess 22. Then, the above assembly is housed in the housing recess 22. At this time, the individual conductive terminals 40a and 40b and the common conductive terminal 50 are attached to the case 20.

[0080] In this way, by forming the assembly before attaching the individual conductive terminals 40a and 40b and the common conductive terminal 50 to the case 20, the conductive material 70 can be filled into the filling space 60 outside the housing recess 22. Therefore, the filling of the conductive material 70 into the filling space 60 becomes easier compared to when the filling of the conductive material 70 into the filling space 60 is performed inside the housing recess 22.

[0081] In the electronic component 1 of this embodiment, by filling the filling space 60 with a conductive agent 70, the terminal electrode 12 and the space forming portion 410 can be connected via the conductive agent 70. This prevents poor contact (open fault) between the inner electrode portion 41 and the terminal electrode 12 caused by the expansion of the resin 30 (Figure 2) filled inside the housing recess 22.

[0082] Furthermore, the filling space 60 is formed in a position closer to the bottom surface 23 than the opening of the housing recess 22. Therefore, the conductive agent 70 filled in the filling space 60 is covered by the resin 30 (Figure 2) filled inside the housing recess 22. This prevents the conductive agent 70 from being exposed to the outside space, improving the moisture resistance of the conductive agent 70 and, consequently, the reliability of the electronic component 1.

[0083] Furthermore, the space-forming portion 410 and the terminal electrode 12 are connected via the conductive material 70 filled in the filling space 60. By physically connecting the space-forming portion 410 and the terminal electrode 12 in this way, poor contact between the inner electrode portion 41 and the terminal electrode 12 caused by the expansion of the resin 30 (Figure 2) can be prevented.

[0084] Furthermore, the space-forming portion 410 protrudes in a direction away from the outer surface (end face 14 and terminal fixing surface 150) of the capacitor chip 10a. As a result, the gap between the outer surface of the capacitor chip 10a and the space-forming portion 410 is increased, and the volume of the filling space 60 can be increased. This increases the volume of conductive material 70 that is filled into the filling space 60, and thus increases the connection strength between the space-forming portion 410 and the terminal electrode 12.

[0085] Furthermore, the terminal fixing surface 150 of the capacitor chip 10a faces the bottom surface 23, and the space forming portion 410 is located around the corner portion 18 of the capacitor chip 10a. In this case, the space forming portion 410 is positioned closer to the bottom surface 23 than the opening of the housing recess 22, and the filling space 60 is also formed closer to the bottom surface 23 than the opening of the housing recess 22. Therefore, the conductive agent 70 filled in the filling space 60 can be covered with resin 30 (Figure 2) so that it is not exposed to the outside space.

[0086] Furthermore, the space-forming portion 410 forms a filling space 60 between itself and the end face 14 and the terminal fixing surface 150, and is bent to surround the corner portion 18. In this case, the filling space 60 is surrounded by the space-forming portion 410 and the end face 14, and also by the space-forming portion 410 and the terminal fixing surface 150. As a result, the conductive agent 70 is less likely to leak out of the filling space 60, and the volume of conductive agent 70 filled in the filling space 60 can be increased.

[0087] Furthermore, the distance (maximum distance) D1 between the space forming portion 410 and the corner portion 18 of the capacitor chip 10a is greater than the distance D2 between the end face facing portion 411 and the end face 14. Therefore, the volume of the filling space 60 can be increased, and the volume of conductive material 70 filled in the filling space 60 can be increased.

[0088] Furthermore, by connecting the individual conductive terminals 40a and 40b shown in Figure 1A to an external circuit and making the common conductive terminal 50 floating, a capacitor circuit consisting of two series capacitor chips 10a and 10b can be constructed.

[0089] Furthermore, by connecting both the individual conductive terminals 40a and 40b and the common conductive terminal 50 to an external circuit, a two-parallel capacitor circuit consisting of capacitor chips 10a and 10b can be constructed.

[0090] Furthermore, as shown in Figure 4, multiple series or parallel capacitor circuits can be configured by connecting multiple cases 20 and then connecting the capacitor chips 10a and 10b housed in each case 20 to each other with conductive terminals between the cases 20.

[0091] The orientation in which the electronic component 1 is mounted on the external circuit is not particularly limited. For example, with the opening surface of the case 20 shown in Figure 1A facing the external circuit (substrate), the opening edge electrode portions 42 of the individual conductive terminals 40a and 40b and / or the opening edge electrode portion 52 of the common conductive terminal 50 may be connected to the external circuit. Alternatively, with the wall 21 of the case 20 (for example, the second surface 20b of the case 20) facing the external circuit (substrate), the side electrode portions 43 of the individual conductive terminals 40a and 40b may be connected to the external circuit.

[0092] Second Embodiment The electronic component 1A of the second embodiment shown in Figure 7 has the same configuration as the electronic component 1 of the first embodiment, except for the points described below. Components common to both the first embodiment and the second embodiment are denoted by the same reference numerals, and their descriptions are omitted.

[0093] Electronic component 1A has individual conductive terminals 40aA and 40bA. The configuration of individual conductive terminal 40aA is the same as, but may be different from, the configuration of individual conductive terminal 40bA.

[0094] Each individual conductive terminal 40aA has an inner electrode portion 41A. The inner electrode portion 41A differs from the inner electrode portion 41 of the first embodiment (Figure 6) in that it has a bent portion 413. The bent portion 413 is bent (protrudes) toward the end face 14 of the capacitor chip 10a. The protruding direction of the bent portion 413 and the protruding direction of the space forming portion 410 are opposite along the X axis.

[0095] The bent portion 413 is continuous with the end face opposing portion 411 and is inclined toward the negative X-axis direction relative to the end face opposing portion 411. The bent portion 413, together with a part of the space forming portion 410, forms a convex shape that protrudes toward the negative X-axis direction.

[0096] The end of the bent portion 413 is in contact with the end face 14 (terminal electrode 12) of the capacitor chip 10a at the position of the first end 410x of the space-forming portion 410, but it may be spaced apart. In this embodiment, the first end 410x of the space-forming portion 410 is the position where the space-forming portion 410 begins to tilt away from the end face 14 relative to the bent portion 413. The space-forming portion 410 is integrated with the bent portion 413.

[0097] The end face opposing portion 511 and the connecting portion 54 of the common conductive terminal 50 are in contact with the end face 13 (terminal electrode 11) of the capacitor chip 10a, but they may be spaced apart. In this embodiment, the capacitor chip 10a is pressed toward the end face opposing portion 511 and the connecting portion 54 due to the elasticity of the bent portion 413.

[0098] In this embodiment, the same effects as in the first embodiment can be obtained. In addition, in this embodiment, since the inner electrode portion 41A has a bent portion 413, the elasticity of the bent portion 413 allows the inner electrode portion 41A to be fixed to the terminal electrode 12.

[0099] Third Embodiment The electronic component 1B of the third embodiment shown in Figure 8 has the same configuration as the electronic component 1A of the second embodiment, except for the points described below. Components common to both the second embodiment and the third embodiment are denoted by the same reference numerals, and their descriptions are omitted.

[0100] As shown in Figure 9, electronic component 1B has individual conductive terminals 40aB and 40bB. The configuration of individual conductive terminal 40aB is the same as that of individual conductive terminal 40bB, but may be different.

[0101] Each individual conductive terminal 40aB has an inner electrode portion 41B. The inner electrode portion 41B does not have a side facing portion 412 (Figure 7), but it does have a space forming portion 410B.

[0102] As shown in Figure 8, the space-forming portion 410B protrudes away from the end face 14 of the capacitor chip 10a (positive X-axis direction), but does not protrude away from the terminal fixing surface 150 (negative Z-axis direction). Therefore, the filling space 60B is formed on the positive X-axis side of the end face 14, but not on the negative Z-axis side of the terminal fixing surface 150. The filling space 60B is approximately triangular in shape and opens downwards. However, the shape of the filling space 60B is not limited to this.

[0103] In this embodiment, the same effects as in the second embodiment can be obtained. In addition, in this embodiment, the side support portion 412 (Figure 7) is omitted from the space forming portion 410B, so the configuration of the space forming portion 410B can be simplified. Also, since the filling space 60B opens downwards, the conductive agent 70 can be easily filled into the interior of the filling space 60B through this opening.

[0104] Fourth Embodiment The electronic component 1C of the fourth embodiment shown in Figure 10 has the same configuration as the electronic component 1B of the third embodiment, except for the points described below. Components common to the third embodiment are denoted by the same reference numerals, and their descriptions are omitted.

[0105] The electronic component 1C has a common conductive terminal 50C. The common conductive terminal 50C has inner electrode portions 51aC and 51bC. The configuration of the inner electrode portion 51aC is the same as, but may be different from, the configuration of the inner electrode portion 51bC.

[0106] The inner electrode portion 51aC differs from the inner electrode portion 51a of the third embodiment in that it does not have a space forming portion 510 and a side support portion 512 (Figure 8). The end face opposing portion 511 is arranged parallel to the end face 13 of the capacitor chip 10a and extends along the Z axis. The lower end of the end face opposing portion 511 may be located below the terminal fixing surface 150 of the capacitor chip 10a.

[0107] The lower end of the end face opposing portion 511 is connected to the terminal electrode 11 via a conductive material 70. The conductive material 70 is attached to the inner surface of the end face opposing portion 511 that forms the connection surface with the terminal electrode 11, but it may also be attached to surfaces other than the inner surface.

[0108] In this embodiment, the same effects as in the third embodiment can be obtained. In addition, in this embodiment, since the end face opposing portion 511 is in surface contact with the terminal electrode 11, electrical connection between them can be ensured. Furthermore, by omitting the space forming portion 510 and the side support portion 512 from the inner electrode portions 51aC and 51bC, the configuration of the inner electrode portions 51aC and 51bC can be simplified.

[0109] Fifth Embodiment The electronic component 1D of the fifth embodiment shown in Figure 11 has the same configuration as the electronic component 1 of the first embodiment, except for the points described below. Components common to both the first embodiment and the fifth embodiment are denoted by the same reference numerals, and their descriptions are omitted.

[0110] Electronic component 1D has individual conductive terminals 40aD and 40bD and a common conductive terminal 50D. The configuration of the individual conductive terminal 40aD is the same as that of the individual conductive terminal 40bD, but may be different.

[0111] As shown in Figure 12, the individual conductive terminal 40aD has an inner electrode portion 41D. As is clear from comparing Figure 12 with Figure 5, the inner electrode portion 41D differs from the inner electrode portion 41 of the first embodiment in that its width along the Y axis is narrower.

[0112] As shown in Figures 11 and 12, the width of the space-forming portion 410 along the Y-axis is smaller than the width of the terminal electrode 12 along the Y-axis. Furthermore, the width of the space-forming portion 410 along the Y-axis is smaller than the width of the opening edge electrode portion 42 or the side electrode portion 43 along the Y-axis. For example, the width of the space-forming portion 410 along the Y-axis is less than or equal to half the width of the terminal electrode 12 along the Y-axis.

[0113] Similarly, the width of the side support portion 412 along the Y-axis is smaller than the width of the terminal electrode 12 along the Y-axis. Also, the width of the side support portion 412 along the Y-axis is smaller than the width of the opening edge electrode portion 42 or the side electrode portion 43 along the Y-axis.

[0114] The end face opposing portion 411 has a wide portion 411w and a narrow portion 411n. The wide portion 411w is wider along the Y-axis than the narrow portion 411n. The width of the wide portion 411w along the Y-axis is the same as, but may be different from, the width of the opening edge electrode portion 42 or the side electrode portion 43 along the Y-axis. The widths of the narrow portion 411n, the space forming portion 410, and the side support portion 412 along the Y-axis are the same, but may be different.

[0115] The common conductive terminal 50D has inner electrode portions 51aD and 51bD. As is clear from comparing Figure 12 and Figure 5, the inner electrode portions 51aD and 51bD differ from the inner electrode portions 51a and 51b of the first embodiment in that the width along the Y axis of the space forming portion 510, the end face facing portion 511, and the side support portion 512 is narrower. The width along the Y axis of the inner electrode portions 51aD and 51bD is smaller than the width along the Y axis of the terminal electrode 11.

[0116] The configuration of the inner electrode portion 51aD is the same as that of the inner electrode portion 51bD, but may be different. The width of the inner electrode portion 51aD along the Y-axis is the same as that of the inner electrode portion 41aD along the Y-axis, but may be different.

[0117] In this embodiment, the same effects as in the first embodiment can be obtained. In addition, in this embodiment, the volume of the filling space 60 (Figure 11) can be adjusted according to the width of the space forming portion 410 along the Y axis. Therefore, the space forming portion 410 and the terminal electrode 12 can be connected via the conductive material while adjusting the amount of conductive material filled into the filling space 60.

[0118] Sixth Embodiment The electronic component 1E of the sixth embodiment shown in Figure 13 has the same configuration as the electronic component 1D of the fifth embodiment, except for the points described below. Components common to the fifth embodiment are denoted by the same reference numerals, and their descriptions are omitted.

[0119] The electronic component 1E has individual conductive terminals 40aE and 40bE and a common conductive terminal 50E. The configuration of the individual conductive terminal 40aE is the same as that of the individual conductive terminal 40bE, but may be different.

[0120] Each individual conductive terminal 40aE has inner electrode portions 41D_1 and 41D_2. The configuration of inner electrode portion 41D_1 is the same as, but may be different from, the configuration of inner electrode portion 41D_2. Inner electrode portion 41D_1 has a space-forming portion 410, an end-face opposing portion 411, and a side support portion 412. Inner electrode portion 41D_2 has a space-forming portion 410, an end-face opposing portion 411, and a side support portion 412.

[0121] The space-forming portion 410 of the inner electrode portion 41D_1 and the space-forming portion 410 of the inner electrode portion 41D_2 are spaced apart along the Y-axis. The end face opposing portion 411 of the inner electrode portion 41D_1 and the end face opposing portion 411 of the inner electrode portion 41D_2 are spaced apart along the Y-axis. The side support portion 412 of the inner electrode portion 41D_1 and the side support portion 412 of the inner electrode portion 41D_2 are spaced apart along the Y-axis.

[0122] The common conductive terminal 50E has inner electrode portions 51aD_1 and 51aD_2 and inner electrode portions 51bD_1 and 51bD_2. The configuration of inner electrode portions 51aD_1 and 51aD_2 is the same as, but may be different from, the configuration of inner electrode portions 51bD_1 and 51bD_2. Also, the configuration of inner electrode portion 51aD_1 is the same as, but may be different from, the configuration of inner electrode portion 51aD_2.

[0123] The inner electrode portion 51aD_1 has a space-forming portion 510, an end-face opposing portion 511, and a side support portion 512. The inner electrode portion 51aD_2 has a space-forming portion 510, an end-face opposing portion 511, and a side support portion 512.

[0124] The space-forming portion 510 of the inner electrode portion 51aD_1 and the space-forming portion 510 of the inner electrode portion 51aD_2 are spaced apart along the Y-axis. The end face opposing portion 511 of the inner electrode portion 51aD_1 and the end face opposing portion 511 of the inner electrode portion 51aD_2 are spaced apart along the Y-axis. The side support portion 512 of the inner electrode portion 51aD_1 and the side support portion 512 of the inner electrode portion 51aD_2 are spaced apart along the Y-axis.

[0125] In this embodiment, the same effects as in the fifth embodiment can be obtained. In addition, in this embodiment, two filled spaces 60 (Figure 13) are formed at the positions of the space-forming portions 410 of the inner electrode portions 41D_1 or 41D_2, and conductive material 70 can be filled into these filled spaces 60. As a result, at these two positions, the two space-forming portions 410 can be connected to the terminal electrodes 12 of the capacitor chip 10a via the conductive material 70. This improves the connection reliability between the individual conductive terminals 40aE and the terminal electrodes 12.

[0126] This disclosure is not limited to the embodiments described above, and can be modified in various ways within the scope of this disclosure.

[0127] In each of the embodiments described above, the chip component is not limited to a capacitor chip, but may be a chip inductor, chip resistor, or the like.

[0128] In the first embodiment described above, the electronic component 1 may be equipped with only individual conductive terminals, or it may be equipped with only common conductive terminals. For example, the case 20 shown in Figure 1A may be provided with four individual conductive terminals, or it may be provided with two common conductive terminals. The same applies to the second to sixth embodiments described above.

[0129] In the first embodiment described above, the side support portion 412 shown in Figure 6 may be omitted. In this case, the terminal fixing surface 150 of the capacitor chip 10a may be supported by the second end 410y of the space forming portion 410. Alternatively, the second end 410y of the space forming portion 410 may be spaced apart from the terminal fixing surface 150 of the capacitor chip 10a.

[0130] In the second embodiment described above, as shown in Figure 7, the individual conductive terminals 40a and 40b were provided with bent portions 413, but the common conductive terminal 50 may also be provided with a bent portion. The same applies to the fourth to sixth embodiments described above.

[0131] Furthermore, the individual conductive terminals 40aD and 40bD of the fifth embodiment and the individual conductive terminals 40aE and 40bE of the sixth embodiment may be provided with a bent portion 413.

[0132] In the sixth embodiment described above, the number of inner electrode portions 41D provided on the individual conductive terminals 40aE or 40bE shown in Figure 14 may be three or more. Furthermore, three or more inner electrode portions 51aD may be formed on the common conductive terminal 50E, or three or more inner electrode portions 51bD may be formed on it.

[0133] In the first embodiment described above, the position of the space-forming portion 410 in the individual conductive terminals 40a (40b) shown in Figure 6 may be changed. For example, the space-forming portion 410 may be located in the center of the housing recess 22 in the Z-axis direction. Alternatively, the space-forming portion 410 may be located at any position between the center of the housing recess 22 in the Z-axis direction and the bottom (bottom surface 23). The same applies to the space-forming portion 510 of the common conductive terminal 50.

[0134] Alternatively, the space-forming portion 410 may be located in the center of the capacitor chip 10a (10b) in the Z-axis direction. Alternatively, the space-forming portion 410 may be located at any position between the center of the capacitor chip 10a (10b) in the Z-axis direction and the lower end (terminal fixing surface 150). The same applies to the space-forming portion 510 of the common conductive terminal 50. [Explanation of symbols]
