DETAILED DESCRIPTION OF THE INVENTION

[0009] The embodiments and modifications described below are merely examples of the present disclosure. The present disclosure is not limited to the embodiments and modifications, and various modifications other than these embodiments and modifications are possible depending on the design, etc., as long as they do not deviate from the technical concept of the present disclosure. The drawings described in the following embodiments and modifications are schematic drawings, and the ratios of the sizes and thicknesses of the components in the drawings do not necessarily reflect the actual dimensional ratios.

[0010] (Embodiment) (1) Overview An overview of electronic component 100 according to this embodiment will be described below with reference to Fig. 1A to Fig. 2. In Fig. 1A, the portion of circuit element 1 (described later) that is housed inside housing 2 (described later) is indicated by a dashed line. In Fig. 2, housing 2 is indicated by a two-dot chain line, and circuit element 1 is indicated by a solid line.

[0011] 1A and 1B, electronic component 100 according to this embodiment includes a circuit element 1, a housing 2, and two terminal members 3. Housing 2 accommodates at least a portion of circuit element 1. Each of the two terminal members 3 is electrically connected to circuit element 1 and protrudes from housing 2 along a first direction D1 (see FIG. 2). As shown in FIG. 2, each of the two terminal members 3 has a first groove portion 32 formed along a second direction D2 that intersects with first direction D1.

[0012] As described above, in electronic component 100 of this embodiment, when solder plating is applied to terminal member 3 and flux creeps up from tip 301 of terminal member 3 (see FIG. 2 ) toward housing 2, the flux that reaches first groove portion 32 enters first groove portion 32 and moves along first groove portion 32. Therefore, first groove portion 32 has the effect of preventing flux from reaching housing 2. In other words, electronic component 100 of this embodiment has the advantage of preventing flux from creeping up to housing 2 when solder plating is applied to terminal member 3. Note that, in the present disclosure, "flux creeping up to housing 2" means that flux adheres to or penetrates into housing 2.

[0013] (2) Detailed configuration (2-1) Overall structure The detailed configuration of electronic component 100 of this embodiment will be described below with reference to FIGS. 1A to 3B. In the following description, the top, bottom, left, right, front, and back directions of electronic component 100 mounted on a substrate (top, bottom, left, right, front, and back in FIG. 1B) are basically defined as top, bottom, left, right, front, and back directions. The top, bottom, left, right, and front and back directions are mutually orthogonal. The orientation in which electronic component 100 is mounted on a substrate is not limited to the above orientations. The arrows indicating the various directions in the drawings are merely shown for explanatory purposes and do not have any physical substance.

[0014] As shown in FIGS. 1A, 1B, and 2, electronic component 100 includes a circuit element 1, a housing 2, and two terminal members 3.

[0015] The electronic component 100 is, for example, an inductor, a common noise filter, a varistor, etc. In the following embodiment, a case where the electronic component 100 is an inductor will be described as an example.

[0016] (2-2) Housing 2, the housing 2 accommodates a part of the circuit element 1 and a part of the terminal member 3. More specifically, the housing 2 accommodates a part of a main body member 11 and a part of a conductive member 12 (to be described later) of the circuit element 1, and a plurality of fixing portions 313 (to be described later) of the terminal member 3.

[0017] The housing 2 of this embodiment is made of a magnetic material. For example, the magnetic material is a mixture of magnetic powder and a binder. The magnetic powder is, for example, a metal powder obtained by atomizing an alloy of Fe, Si, Cr, or the like, and the binder is, for example, a thermosetting resin such as an epoxy resin or a silicone resin. The housing 2 is formed by embedding a portion of the main body member 11 and the conductive member 12 of the circuit element 1 in the mixture of the magnetic powder and binder, press-molding the mixture, and then curing the binder. In this case, the magnetic material is also disposed inside the main body member 11, so the housing 2 functions as the magnetic core of the main body member 11.

[0018] As shown in FIGS. 1A and 1B , the housing 2 of this embodiment has a rectangular parallelepiped shape having a top surface 21, a bottom surface 22, a pair of first side surfaces 23 and 24, and a pair of second side surfaces 25 and 26. The rectangular parallelepiped shape does not necessarily have to be a shape that conforms completely to a rectangular parallelepiped, as long as it conforms to a rectangular parallelepiped as a whole. The top surface 21 and the bottom surface 22 face each other in the up-down direction. The pair of first side surfaces 23 and 24 face each other in the left-right direction between the top surface 21 and the bottom surface 22. Similarly, the pair of second side surfaces 25 and 26 face each other in the front-to-rear direction between the top surface 21 and the bottom surface 22. That is, the top surface 21 is the upper surface of the housing 2, and the bottom surface 22 is the lower surface of the housing 2. The first side surface 23 is the left surface of the housing 2, and the first side surface 24 is the right surface of the housing 2. Similarly, the second side surface 25 is the front surface of the housing 2, and the second side surface 26 is the rear surface of the housing 2.

[0019] (2-3) Circuit elements The circuit element 1 has a main body member 11 and two conductive members 12. Since the electronic component 100 is an inductor, the main body member 11 is a coil formed by spirally winding a conductor such as a round wire or a rectangular conductor wire.

[0020] 2, each of the two conductive members 12 is a member in which both ends of the main body member 11 are drawn out to the outside of the housing 2. More specifically, each of the two conductive members 12 is a member in which both ends of the main body member 11 are drawn out from the housing 2 along a first direction D1 (details will be described later) in which the terminal members 3 protrude. Furthermore, each of the two conductive members 12 is electrically connected to the terminal members 3. That is, each of the two conductive members 12 is drawn out from the housing 2 along the first direction D1 and electrically connected to the terminal members 3.

[0021] Parts of the two conductive members 12 protrude from the housing 2 in the first direction D1 and are exposed to the outside of the housing 2. In this embodiment, the two conductive members 12 protrude from each of a pair of first side surfaces 23, 24 of the housing 2 in the first direction D1, as shown in Fig. 2. More specifically, one of the two conductive members 12 protrudes from the first side surface 23 in the first direction D1 (to the left), and the other conductive member 12 protrudes from the first side surface 24 in the first direction D1 (to the right).

[0022] The conductive member 12 is not connected to the terminal member 3 inside the housing 2, but is connected to the terminal member 3 outside the housing 2. More specifically, the conductive member 12 is housed in a recess 34 (see FIGS. 2 and 3B) of the terminal member 3, which will be described later, and is connected to the terminal member 3 by welding or the like.

[0023] In this embodiment, the two conductive members 12 correspond one-to-one to the two terminal members 3, and each of the two conductive members 12 protrudes along the corresponding terminal member 3. More specifically, of the two conductive members 12, the conductive member 12 protruding from the first side surface 23 corresponds to the terminal member 3 on the left, and the conductive member 12 protruding from the first side surface 24 corresponds to the terminal member 3 on the right.

[0024] (2-4) Terminal parts Each of the two terminal members 3 is a member used when electronic component 100 is electrically connected to an external circuit (not shown). That is, electronic component 100 is electrically connected to the external circuit via the two terminal members 3. Each of the two terminal members 3 is mounted on a printed circuit board (not shown) in a state where it is bent along housing 2 (see FIG. 1B), thereby being electrically connected to the external circuit.

[0025] The two terminal members 3 are aligned in the left-right direction. As shown in FIG. 2, each of the two terminal members 3 has a base 31. The base 31 is a plate member made of a metal material such as phosphor bronze or copper. That is, each of the two terminal members 3 is plate-shaped. The thickness X2 of the base 31 (see FIG. 3A) is, for example, 0.2 mm.

[0026] The detailed structure of the base portion 31 of each of the two terminal members 3 before being bent along the housing 2 (see FIG. 2) will be described below.

[0027] The base 31 of each of the two terminal members 3 protrudes from the housing 2 in the first direction D1. More specifically, the base 31 of the left terminal member 3 of the two terminal members 3 protrudes (to the left) from the first side surface 23 of the housing 2 in the first direction D1. On the other hand, the base 31 of the right terminal member 3 of the two terminal members 3 protrudes (to the right) from the first side surface 24 of the housing 2 in the first direction D1.

[0028] The base 31 has a first portion 311 and a second portion 312. The first portion 311 has a tapered shape in which the width dimension (dimension in the front-rear direction) gradually decreases from a first end on the housing 2 side in the first direction D1 to a second end on the opposite side. The second portion 312 extends from the second end of the first portion 311 along the first direction D1. The width dimension of the second portion 312 is the same as the width dimension of the second end of the first portion 311. The extending tip of the second portion 312 is the tip 301 of each of the two terminal members 3. Hereinafter, the "tip 301 of the terminal member 3" will also be referred to as the "tip 301 of the base 31."

[0029] Two fixed portions 313 are provided at a first end of the first portion 311 on the housing 2 side in the first direction D1. The two fixed portions 313 are aligned in the front-to-rear direction. In this embodiment, the two fixed portions 313 are semicircular plate members.

[0030] In this embodiment, the two fixing portions 313 protrude in the first direction D1 from a first end of the first portion 311. More specifically, the two fixing portions 313 in the base 31 of the left terminal member 3 protrude rightward from the first end (right end) of the first portion 311. Similarly, the two fixing portions 313 in the base 31 of the right terminal member 3 protrude leftward from the first end (left end) of the first portion 311.

[0031] The base 31 of each of the two terminal members 3 is solder-plated before being bent along the housing 2, that is, while it protrudes in a direction perpendicular (left-right direction) to the first side faces 23, 24 (see FIG. 1A). As a result, the two terminal members 3 have improved solder wettability when mounted on a printed circuit board.

[0032] A method for solder plating the base 31 will be specifically described. The base 31 is immersed in a flux solution from the tip 301 side, so that the flux solution is applied to the base 31. Next, the base 31 to which the flux solution has been applied is immersed in molten solder from the tip 301 side, so that the solder plating is applied. Note that the flux solution referred to here is, for example, a mixture of a flux such as a rosin-based flux and a solvent such as isopropyl alcohol.

[0033] 1B, the solder-plated base 31 is bent along the housing 2. More specifically, the solder-plated base 31 of the left terminal member 3 is bent along the first side surface 23 and bottom surface 22 of the housing 2. Similarly, the solder-plated base 31 of the right terminal member 3 (not shown in FIG. 1B) is bent along the first side surface 24 and bottom surface 22 of the housing 2.

[0034] 2, each of the two terminal members 3 further has a plurality of first grooves 32 and a plurality of second grooves 33. The first grooves 32 correspond to the grooves of the present disclosure. That is, the grooves of the present disclosure are the first grooves 32.

[0035] Each of the plurality of first grooves 32 is formed on the predetermined surface 30 of the base 31 along a second direction D2 intersecting with the first direction D1. That is, each of the plurality of first grooves 32 is formed on the predetermined surface 30 of the base 31 along a direction intersecting with the direction in which the base 31 protrudes. In this embodiment, the number of first grooves 32 included in each of the two terminal members 3 is three. Note that the "predetermined surface 30 of the base 31" in this disclosure refers to the surface exposed to the outside of the housing 2 (the surface not in contact with the housing 2) when the base 31 is bent along the housing 2 (see FIG. 1B), i.e., the surface to be mounted on a printed circuit board. In other words, the "predetermined surface 30 of the base 31" refers to the upper surface of the base 31 before it is bent along the housing 2, i.e., when it protrudes along a direction perpendicular (left-right direction) to the first side surfaces 23 and 24 (see FIG. 1A).

[0036] Because each of the two terminal members 3 has multiple first groove portions 32, when flux creeps up from the tip 301 of the terminal member 3 toward the housing 2, the flux that reaches each of the multiple first groove portions 32 enters each of the multiple first groove portions 32 and moves along each of the multiple first groove portions 32. Therefore, each of the multiple first groove portions 32 has the effect of further preventing the flux from reaching the housing 2. In other words, the electronic component 100 of this embodiment has the advantage of further preventing the flux from creeping up to the housing 2 when solder plating is applied to the terminal members 3.

[0037] 3A, the cross-sectional shape of each of the plurality of first groove portions 32 is semicircular. Note that the cross-sectional shape of each of the plurality of first groove portions 32 is not limited to semicircular and may be, for example, rectangular, triangular, or U-shaped. As an example, the plurality of first groove portions 32 are formed by cutting using a blade, press working using a mold, cutting using a laser beam, or the like.

[0038] The depth X3 (see FIG. 3A) of each of the plurality of first groove portions 32 is desirably 0.01 mm or more and 0.1 mm or less, for example, 0.04 mm. In the present disclosure, the "depth X3 of each of the plurality of first groove portions 32" refers to the dimension of each of the plurality of first groove portions 32 in the normal direction to the predetermined surface 30 of the base 31, and more specifically, the distance from the predetermined surface 30 of the base 31 to the bottom surface of each of the plurality of first groove portions 32.

[0039] Furthermore, it is desirable that the depth X3 of the plurality of first groove portions 32 be greater than the depth X4 of the plurality of second groove portions 33, which will be described later. With this configuration, each of the plurality of first groove portions 32 has the effect of making it easier to prevent flux from reaching the housing 2. That is, electronic component 100 of this embodiment has the advantage that it makes it easier to prevent flux from creeping up to the housing 2 when solder plating is applied to terminal members 3.

[0040] Similarly, the width of the plurality of first groove portions 32 (see FIG. 2) is preferably 0.01 mm or more and 0.1 mm or less, for example, 0.05 mm. The distance between two adjacent first groove portions 32 in the second direction D2 is preferably 0.02 mm or more and 0.5 mm or less, for example, 0.2 mm. In the present disclosure, the "width of the plurality of first groove portions 32" refers to the dimension of each of the plurality of first groove portions 32 in the direction in which a plane perpendicular to the extension direction of each of the plurality of first groove portions 32 intersects with the predetermined plane 30.

[0041] In the present embodiment, each of the plurality of first grooves 32 contacts both ends of the terminal member 3 (base 31) in the second direction D2. More specifically, each of the plurality of first grooves 32 contacts both ends of the first portion 311 of the base 31 in the second direction D2. Specifically, the front end of each of the plurality of first grooves 32 in the second direction D2 contacts the front end of the first portion 311 of the base 31 in the second direction D2, and the rear end of each of the plurality of first grooves 32 in the second direction D2 contacts the rear end of the first portion 311 of the base 31 in the second direction D2. That is, in the present embodiment, each of the plurality of first grooves 32 is formed across both ends of the first portion 311 of the base 31 in the second direction D2. This configuration has the effect of preventing flux from creeping up to the housing 2 through each of the plurality of first grooves 32 when solder plating is performed on the terminal member 3. In short, there is an advantage that when solder plating is applied to the terminal members 3, the flux can be further prevented from creeping up to the housing 2.

[0042] The plurality of first grooves 32 are formed on the predetermined surface 30 of the base 31 so that a distance X1 (see FIG. 2) in the first direction D1 between the housing 2 and a first groove 32 that is closest to the housing 2 in the first direction D1 is at least twice the thickness X2 (see FIG. 3A) of the terminal member 3 (base 31). As an example, assuming that the thickness of the base 31 is 0.2 mm, the plurality of first grooves 32 are formed so that a distance X1 in the first direction D1 between the housing 2 and a first groove 32 that is closest to the housing 2 is at least 0.4 mm. The above configuration has the advantage that a bending position Y1 (see FIG. 2) when each of the two terminal members 3 is bent along the housing 2 can be prevented from overlapping with each of the plurality of first grooves 32. Note that the "distance X1 in the first direction D1 between the housing 2 and the first groove 32 that is closest to the housing 2 in the first direction D1 among the multiple first grooves 32" referred to here is the distance in the first direction D1 between the side surface of the first groove 32 closest to the housing 2 that faces the housing 2 and the first side surfaces 23, 24 of the housing 2. In other words, the "distance X1 in the first direction D1 between the housing 2 and the first groove 32 that is closest to the housing 2 in the first direction D1 among the multiple first grooves 32" for the left-side terminal member 3 is the distance in the first direction D1 between the right side surface of the rightmost first groove 32 and the first side surface 23 of the housing 2. Similarly, in the right-side terminal member 3, "the distance X1 in the first direction D1 between the housing 2 and the first groove 32 that is located closest to the housing 2 in the first direction D1 among the multiple first grooves 32" refers to the distance in the first direction D1 between the left side surface of the leftmost first groove 32 and the first side surface 24 of the housing 2. Also, the dotted line Y1 shown in Fig. 2 is merely shown for the purpose of explanation and does not have any substance.

[0043] In this embodiment, each of the multiple first groove portions 32 has a first portion 321 and a second portion 322. In this embodiment, the first portion 321 is a rear portion of each of the multiple first groove portions 32, and the second portion 322 is a front portion of each of the multiple first groove portions 32.

[0044] The first portion 321 has a first end (rear end) that contacts one of the ends of the terminal member 3 in the second direction D2, and a second end (front end) opposite the first end. The first portion 321 is formed so that the distance from (the first side surfaces 23, 24 of) the housing 2 increases in the first direction D1 as it approaches the first end from the second end. That is, the first portion 321 is formed obliquely with respect to the first side surfaces 23, 24 so that the first end is located closer to the tip 301 of the terminal member 3 than the second end.

[0045] Similarly, the second portion 322 has a third end (front end) that contacts one of the ends of the terminal member 3 in the second direction D2, and a fourth end (rear end) opposite the third end. The second portion 322 is formed so that the distance from (the first side surfaces 23, 24 of) the housing 2 increases in the first direction D1 as it approaches the third end from the fourth end. That is, the second portion 322 is formed obliquely with respect to the first side surfaces 23, 24 so that the third end is located closer to the tip 301 of the terminal member 3 than the fourth end.

[0046] According to the above configuration, when flux creeps up from the tip 301 of the terminal member 3 toward the housing 2, the flux that reaches each of the plurality of first grooves 32 enters the corresponding first groove 32 and moves along the corresponding first groove 32 toward the tip 301 of the terminal member 3. That is, the flux that reaches each of the plurality of first grooves 32 moves toward the opposite side of the housing 2. Therefore, each of the plurality of first grooves 32 has the effect of more reliably preventing the flux from reaching the housing 2. That is, the electronic component 100 of this embodiment has the advantage of more reliably preventing the flux from creeping up to the housing 2 when solder plating is applied to the terminal member 3.

[0047] In this embodiment, as shown in FIG. 2, each of the multiple first groove portions 32 is divided into a first divided body P1 and a second divided body P2. The first divided body P1 is the first portion 321 described above, and the second divided body P2 is the second portion 322 described above. The conductive member 12 of the circuit element 1 is located between the first divided body P1 and the second divided body P2 in the second direction D2. In other words, the first divided body P1 and the second divided body P2 are formed in positions facing each other across the conductive member 12 in the second direction D2. This configuration has the advantage of preventing flux from creeping up to the housing 2 when solder plating is applied to the terminal members 3, even when each of the two conductive members 12 is drawn out along the terminal members 3 and electrically connected to the terminal members 3.

[0048] In this embodiment, as shown in FIGS. 2 and 3B , each of the two terminal members 3 is provided between the first divided body P1 and the second divided body P2 along the first direction D1 and further includes a recess 34 that accommodates a corresponding one of the two conductive members 12. More specifically, the recess 34 in each of the two terminal members 3 accommodates the conductive member 12 of the two conductive members 12 that corresponds to the terminal member 3 (i.e., the conductive member 12 that protrudes along the terminal member 3). More specifically, the recess 34 in the left terminal member 3 accommodates the conductive member 12 of the two conductive members 12 that protrudes from the first side surface 23. Similarly, the recess 34 in the right terminal member 3 accommodates the conductive member 12 of the two conductive members 12 that protrudes from the first side surface 24. The recess 34 is provided in a predetermined surface 30 of the base 31. In this disclosure, "the recess 34 accommodates the conductive member 12" includes both the case where the recess 34 accommodates a portion of the conductive member 12 (e.g., the lower portion of the conductive member 12) (see FIG. 3B) and the case where the recess 34 accommodates the entire conductive member 12 (not shown).

[0049] The first divided body P1 and the second divided body P2 are in contact with the recess 34. More specifically, the front end of the first divided body P1 is in contact with the rear end of the recess 34, and the rear end of the second divided body P2 is in contact with the front end of the recess 34. This configuration has the advantage that even when each of the two conductive members 12 is drawn out along the terminal members 3 and electrically connected to the terminal members 3, it is possible to further prevent flux from creeping up to the housing 2 when solder plating is applied to the terminal members 3.

[0050] The cross-sectional shape of the recess 34 is rectangular as shown in Fig. 3B. Note that the cross-sectional shape of the recess 34 is not limited to a rectangular shape and may be, for example, a triangular shape, a semicircular shape, or a U-shape. As an example, the recess 34 is formed by press working using a mold.

[0051] In this embodiment, the depth of the recess 34 is greater (deeper) than the depth X4 of the plurality of second groove portions 33, and the width of the recess 34 is greater than the width of the plurality of second groove portions 33. Note that the depth and width of the recess 34 may be any dimensions as long as they are capable of accommodating the conductive member 12.

[0052] Each of the plurality of second grooves 33 is located on the predetermined surface 30 of the base 31 between the tip 301 of the base 31 and the plurality of first grooves 32 in the first direction D1, and is formed from the tip 301 of the base 31 along the first direction D1. In other words, the plurality of second grooves 33 are formed on the predetermined surface 30 of the base 31 from the tip 301 of the base 31 toward the housing 2. The plurality of second grooves 33 are aligned in a second direction D2 that intersects with the first direction D1. By each of the two terminal members 3 having the second groove 33, when solder plating is performed on each of the two terminal members 3, there is an advantage in that it becomes easier for flux to creep up from the tip 301 of the terminal member 3 toward the housing 2 through the second groove 33, making it easier for the flux to creep up to the desired position (to the position where the plurality of first grooves 32 are formed). Furthermore, in this embodiment, since each of the two terminal members 3 has a plurality of second groove portions 33, there is an advantage that it becomes easier to make the flux creep up to the target position.

[0053] The cross-sectional shape of each of the second groove portions 33 is semicircular as shown in Fig. 3B. Note that the cross-sectional shape of each of the second groove portions 33 is not limited to semicircular and may be, for example, rectangular, triangular, or U-shaped. As an example, the second groove portions 33 are formed by cutting using a blade, press working using a mold, cutting with a laser beam, or the like.

[0054] The depth X4 (see FIG. 3B) of the second grooves 33 is preferably 0.01 mm or more and 0.1 mm or less, for example, 0.02 mm. In the present disclosure, the "depth X4 of the second grooves 33" refers to the dimension of the second grooves 33 in the normal direction to the predetermined surface 30 of the base 31, and more specifically, the distance from the predetermined surface 30 of the base 31 to the bottom surfaces of the second grooves 33.

[0055] Similarly, the width of the plurality of second groove portions 33 (see FIG. 2) is preferably 0.01 mm or more and 0.1 mm or less, for example, 0.02 mm. Furthermore, the interval between two adjacent second groove portions 33 in the second direction D2 is preferably 0.02 mm or more and 0.5 mm or less, for example, 0.2 mm. In the present disclosure, the "width of the plurality of second groove portions 33" refers to the dimension of each of the plurality of second groove portions 33 in the second direction D2. Note that in FIGS. 2 and 3B, for ease of viewing, the number of second groove portions 33 is reduced, and the width of the plurality of second groove portions 33 and the interval between two adjacent second groove portions 33 are changed.

[0056] As shown in FIG. 2 , the ends 331 of the multiple second grooves 33 on the housing 2 side are in contact with one of the multiple first grooves 32. More specifically, the ends 331 of the multiple second grooves 33 on the housing 2 side are in contact with the first groove 32 of the multiple first grooves 32 that is closest to the tip 301 of the terminal member 3 in the first direction D1. That is, in the base 31 of the left terminal member 3, the ends 331 of the multiple second grooves 33 on the housing 2 side are in contact with the first groove 32 that is located on the leftmost side of the multiple first grooves 32. On the other hand, in the base 31 of the right terminal member 3, the ends 331 of the multiple second grooves 33 on the housing 2 side are in contact with the first groove 32 that is located on the rightmost side of the multiple first grooves 32. According to the above configuration, when flux creeps up from the tip 301 of the terminal member 3 toward the housing 2 through each of the plurality of second groove portions 33, the flux that reaches the first groove portion 32 that is in contact with each of the plurality of second groove portions 33 has the advantage of being more likely to enter the above-mentioned first groove portion 32.

[0057] 2, each of the plurality of first grooves 32 is divided into a first divided body P1 and a second divided body P2, and the conductive member 12 of the circuit element 1 is located between the first divided body P1 and the second divided body P2 in the second direction D2. Therefore, the housing 2-side end 331 of the plurality of second grooves 33 provided rearward of the conductive member 12 contacts the first divided body P1 of the first groove 32 provided closest to the tip 301 of the terminal member 3 in the first direction D1 among the plurality of first grooves 32. Meanwhile, the housing 2-side end 331 of the plurality of second grooves 33 provided in front of the conductive member 12 contacts the second divided body P2 of the first groove 32 provided closest to the tip 301 of the terminal member 3 in the first direction D1 among the plurality of first grooves 32.

[0058] (3) Effects In electronic component 100 according to this embodiment, terminal member 3 has first groove 32 formed along second direction D2 intersecting first direction D1. As a result, in electronic component 100 according to this embodiment, when solder plating is applied to terminal member 3 and flux creeps up from tip 301 of terminal member 3 (see FIG. 2 ) toward housing 2, the flux that reaches first groove 32 enters first groove 32 and moves along first groove 32. Therefore, first groove 32 has the effect of preventing flux from reaching housing 2. In other words, electronic component 100 according to this embodiment has the advantage of preventing flux from creeping up to housing 2 when solder plating is applied to terminal member 3.

[0059] In electronic component 100 according to this embodiment, terminal member 3 further includes second groove 33 located between tip 301 of base 31 and first groove 32 in first direction D1 and formed from tip 301 of base 31 along first direction D1. This has the advantage that when solder plating is applied to each of the two terminal members 3, flux tends to creep up from tip 301 of terminal member 3 toward housing 2 through second groove 33, making it easier for the flux to creep up to the desired position (the position where first groove 32 is formed).

[0060] In electronic component 100 according to this embodiment, end 331 of second groove 33 on the housing 2 side is in contact with first groove 32. This has the advantage that when flux creeps up from tip 301 of terminal member 3 through second groove 33 toward housing 2, the flux that reaches first groove 32 in contact with second groove 33 can easily enter the first groove 32.

[0061] Electronic component 100 according to this embodiment has a plurality of second groove portions 33, including the above-described second groove portion 33. This has the advantage of making it easier for the flux to creep up to the target position.

[0062] In the electronic component 100 according to this embodiment, the first groove 32 has a first portion 321 and a second portion 322. The first portion 321 has a first end (rear end) that contacts one of the ends of the terminal member 3 in the second direction D2, and a second end (front end) opposite the first end. In the first direction D1, the distance of the first portion 321 from (the first side surfaces 23, 24 of) the housing 2 increases as the first portion 321 approaches the first end from the second end. Similarly, the second portion 322 has a third end (front end) that contacts one of the ends of the terminal member 3 in the second direction D2, and a fourth end (rear end) opposite the third end. In the first direction D1, the distance of the second portion 322 from (the first side surfaces 23, 24 of) the housing 2 increases as the second portion 321 approaches the third end from the fourth end. As a result, when flux creeps up from tip 301 of terminal member 3 toward housing 2, the flux that reaches first groove 32 enters first groove 32 and moves along first groove 32 toward tip 301 of terminal member 3. In other words, the flux that reaches first groove 32 moves in the opposite direction from housing 2. Therefore, first groove 32 has the effect of more reliably preventing flux from reaching housing 2. In other words, electronic component 100 of this embodiment has the advantage of more reliably preventing flux from creeping up to housing 2 when solder plating is applied to terminal member 3.

[0063] The electronic component 100 according to this embodiment has a plurality of first groove portions 32, including the above-described first groove portion 32. As a result, when flux creeps up from the tip 301 of the terminal member 3 toward the housing 2, the flux that reaches each of the plurality of first groove portions 32 enters each of the plurality of first groove portions 32 and moves along each of the plurality of first groove portions 32. Therefore, each of the plurality of first groove portions 32 has the effect of further preventing the flux from reaching the housing 2. In other words, the electronic component 100 according to this embodiment has the advantage of further preventing the flux from creeping up to the housing 2 when solder plating is applied to the terminal member 3.

[0064] 2, in the electronic component 100 according to this embodiment, each of the plurality of first groove portions 32 is divided into a first divided body P1 and a second divided body P2, and the conductive member 12 of the circuit element 1 is located between the first divided body P1 and the second divided body P2 in the second direction D2. This has the advantage that even when each of the two conductive members 12 is drawn out along the terminal members 3 and electrically connected to the terminal members 3, it is possible to prevent flux from creeping up to the housing 2 when solder plating is applied to the terminal members 3.

[0065] 2 and 3B, in electronic component 100 according to this embodiment, each of two terminal members 3 is provided between first divided body P1 and second divided body P2 along first direction D1, and further has a recess 34 that accommodates a corresponding one of two conductive members 12, and first divided body P1 and second divided body P2 are in contact with recess 34. This has the advantage that even when each of two conductive members 12 is drawn out along terminal members 3 and electrically connected to terminal members 3, it is possible to further prevent flux from creeping up to housing 2 when solder plating is applied to terminal members 3.

[0066] (4) Variations The above-described embodiment is merely one of various embodiments of the present disclosure. The above-described embodiment can be modified in various ways depending on the design, etc., as long as the object of the present disclosure can be achieved. The following modifications may be implemented in appropriate combination. The same components as those in the above-described embodiment are denoted by the same reference numerals, and the description thereof will be omitted.

[0067] (4-1) First Modification In electronic component 100 of the above-described embodiment, two conductive members 12 of circuit element 1 are members in which both ends of main body member 11 are drawn out to the outside of housing 2. However, as shown in Fig. 4, in electronic component 100A of the first modification, two conductive members 12A of circuit element 1 are members in which both ends of main body member 11 are not drawn out to the outside of housing 2 but are extended inside housing 2. Note that Fig. 4 shows electronic component 100A of the first modification from the same perspective as Fig. 2.

[0068] As shown in FIG. 4, electronic component 100A of the first modified example includes circuit element 1A, housing 2, and two terminal members 3A.

[0069] The circuit element 1A has a main body member 11 and two conductive members 12A. Each of the two conductive members 12A is a member in which both ends of the main body member 11 do not extend to the outside of the housing 2 but extend within the housing 2. The two conductive members 12A correspond one-to-one to the two terminal members 3A, and each of the two conductive members 12A extends toward one of two fixing portions 313A (described later) included in the corresponding terminal member 3A. As an example, each of the two conductive members 12A is electrically connected to one of the fixing portions 313A by welding or the like.

[0070] More specifically, of the two conductive members 12, the conductive member 12 extending to the left corresponds to the left terminal member 3, and extends toward the rear fixing portion 313A of two fixing portions 313A (described later) included in the left terminal member 3. Similarly, of the two conductive members 12, the conductive member 12 extending to the right corresponds to the right terminal member 3, and extends toward the front fixing portion 313A of two fixing portions 313A (described later) included in the right terminal member 3.

[0071] The two terminal members 3A are aligned in the left-right direction. The two terminal members 3A have bases 31A. The bases 31A of each of the two terminal members 3A protrude from the housing 2 in the first direction D1. The bases 31A of the left terminal member 3A of the two terminal members 3A protrude (to the left) from the first side surface 23 along the first direction D1. Similarly, the bases 31A of the right terminal member 3A of the two terminal members 3A protrude (to the right) from the first side surface 24 along the first direction D1. Hereinafter, the configuration of the bases 31A, which is the same as the bases 31 in the above-described embodiment, will be omitted as appropriate.

[0072] The base 31A is a rectangular plate member made of a metal material such as phosphor bronze or copper. Two fixed portions 313A are provided at the end of the base 31A facing the housing 2 in the first direction D1 and are embedded and fixed in the housing 2. The two fixed portions 313A are aligned in the front-to-rear direction. The two fixed portions 313A are semicircular plate members. The two fixed portions 313A may also be rectangular plate members.

[0073] The two fixing portions 313A protrude along the first direction D1 from the end of the base 31A facing the housing 2 in the first direction D1. More specifically, the two fixing portions 313A on the base 31A of the left terminal member 3A protrude rightward from the end (right end) of the base 31A facing the housing 2 in the first direction D1. Similarly, the two fixing portions 313 on the base 31A of the right terminal member 3A protrude leftward from the end (left end) of the base 31A facing the housing 2 in the first direction D1.

[0074] Each of the two terminal members 3A further has a plurality of first groove portions 32A and a plurality of second groove portions 33. Hereinafter, description of the configuration of the first groove portions 32A, which is similar to the first groove portions 32 in the above-described embodiment, will be omitted as appropriate.

[0075] Unlike the first grooves 32 in the above-described embodiment, each of the first grooves 32A in the first modified example is not divided into a first divided body P1 and a second divided body P2. That is, in the base 31A of the first modified example, a plurality of first grooves 32A that are not divided in the second direction D2 are formed across both ends of the base 31A in the second direction D2.

[0076] Each of the plurality of first groove portions 32A has a first portion 321A, a second portion 322A, and a third portion 323A. In the first modification, the first portion 321A is a rear portion of each of the plurality of first groove portions 32A, the second portion 322A is a front portion of each of the plurality of first groove portions 32A, and the third portion 323A is a central portion in the front-to-rear direction of each of the plurality of first groove portions 32A.

[0077] The first portion 321A has a first end (rear end) that contacts one of the ends of the terminal member 3A in the second direction D2, and a second end (front end) opposite the first end. The first portion 321A is formed such that the distance from (the first side surfaces 23, 24 of) the housing 2 increases in the first direction D1 as it approaches the first end from the second end. That is, the first portion 321A is formed obliquely with respect to the first side surfaces 23, 24 so that the first end is located closer to the tip 301 of the terminal member 3A than the second end.

[0078] Similarly, the second portion 322A has a third end (front end) that contacts one of the ends of the terminal member 3A in the second direction D2, and a fourth end (rear end) opposite the third end. The second portion 322A is formed so that the distance from the housing 2 (first side faces 23, 24) increases in the first direction D1 as it approaches the third end from the fourth end. That is, the second portion 322A is formed obliquely with respect to the first side faces 23, 24 so that the third end is located closer to the tip 301 of the terminal member 3A than the fourth end.

[0079] The third portion 323A is formed to join the second end (front end) of the first portion 321A and the fourth end (rear end) of the second portion 322A.

[0080] According to the above configuration, when flux creeps up from tip 301 of terminal member 3A toward housing 2, the flux that reaches each of first grooves 32A enters each of first grooves 32A and moves along each of first grooves 32A toward tip 301 of terminal member 3A. That is, the flux that reaches each of first grooves 32A moves toward the opposite side of housing 2. Therefore, each of first grooves 32A has the effect of more reliably preventing flux from reaching housing 2. That is, electronic component 100A of the first modification has the advantage of more reliably preventing flux from creeping up to housing 2 when solder plating is applied to terminal member 3A.

[0081] (4-2) Second Modification In electronic component 100 of the above-described embodiment, two conductive members 12 of circuit element 1 are members in which both ends of main body member 11 are drawn out to the outside of housing 2.

Note that Fig. 5 shows electronic component 100B of the second modification from the same perspective as Fig. 2 .

[0082] Furthermore, in electronic component 100 of the above-described embodiment, two fixing portions 313 are provided at the end of base 31 on the housing 2 side in first direction D1. However, in electronic component 100B of the second modification, as shown in Fig. 5 , the portion extending from the end of base 31 on the housing 2 side in first direction D1 toward housing 2 is fixing portion 313B.

[0083] As shown in FIG. 5, electronic component 100B of the second modified example includes circuit element 1B, housing 2, and two terminal members 3B.

[0084] The circuit element 1B includes a main body member 11 and two conductive members 12B. Each of the two conductive members 12B is a member in which both ends of the main body member 11 do not extend to the outside of the housing 2 but extend within the housing 2. The two conductive members 12B correspond one-to-one to the two terminal members 3B, and each of the two conductive members 12B extends toward a fixing portion 313B (described later) of the corresponding terminal member 3B. That is, each of the two conductive members 12B extends along the first direction D1. As an example, each of the two conductive members 12B is electrically connected to the fixing portion 313B by welding or the like.

[0085] The two terminal members 3B are aligned in the left-right direction. The two terminal members 3B have bases 31B. The bases 31B of each of the two terminal members 3B protrude from the housing 2 in the first direction D1. The bases 31B of the left terminal member 3B of the two terminal members 3B protrude (to the left) from the first side surface 23 along the first direction D1. Similarly, the bases 31B of the right terminal member 3B of the two terminal members 3B protrude (to the right) from the first side surface 24 along the first direction D1. Hereinafter, the configuration of the bases 31B, which is the same as the bases 31 in the above-described embodiment, will be omitted as appropriate.

[0086] The base 31B is a rectangular plate member made of a metal material such as phosphor bronze or copper. A fixed portion 313B is provided at the end of the base 31B facing the housing 2 in the first direction D1. The fixed portion 313B is embedded in and fixed to the housing 2. The fixed portion 313B is a portion of the end of the base 31B facing the housing 2 in the first direction D1 that extends toward the housing 2.

[0087] More specifically, the fixed portion 313B of the base 31B of the left terminal member 3B is a portion where the end (right end) of the base 31B facing the housing 2 in the first direction D1 extends to the right. Similarly, the fixed portion 313B of the base 31B of the right terminal member 3B is a portion where the end (left end) of the base 31B facing the housing 2 in the first direction D1 extends to the left.

[0088] Each of the two terminal members 3B further has a plurality of first groove portions 32B and a plurality of second groove portions 33. Hereinafter, description of the configuration of the first groove portions 32B, which is similar to the first groove portions 32 in the above-described embodiment, will be omitted as appropriate.

[0089] Unlike the first grooves 32 in the above-described embodiment, each of the first grooves 32B in the second modified example is not divided into a first divided body P1 and a second divided body P2. That is, in the base 31B of the second modified example, a plurality of first grooves 32B that are not divided in the second direction D2 are formed across both ends of the base 31B in the second direction D2.

[0090] Each of the plurality of first grooves 32B has a first portion 321B, a second portion 322B, and a third portion 323B. In the second modification, the first portion 321B is a rear portion of each of the plurality of first grooves 32B, the second portion 322B is a front portion of each of the plurality of first grooves 32B, and the third portion 323B is a central portion in the front-to-rear direction of each of the plurality of first grooves 32B. The configurations of the first portion 321B, the second portion 322B, and the third portion 323B of the second modification are similar to the configurations of the first portion 321A, the second portion 322A, and the third portion 323A of the first modification, and therefore detailed description thereof will be omitted.

[0091] (4-3) Third Modification In the electronic component 100 of the above-described embodiment, each of the two terminal members 3 further includes a plurality of first grooves 32 and a plurality of second grooves 33. However, as shown in Fig. 6, in an electronic component 100C of a third modification, each of the two terminal members 3C includes a plurality of first grooves 32 but does not include a plurality of second grooves 33. Note that Fig. 6 shows the electronic component 100C of the third modification from the same perspective as Fig. 2.

That is, each of the two terminal members 3C does not have a plurality of second groove portions 33 formed from the tip 301 of the base 31 along the first direction D1.

[0094] (4-4) Fourth Modification In electronic component 100 according to the above-described embodiment, ends 331 of the second grooves 33 on the housing 2 side are in contact with any of the first grooves 32. However, as shown in Fig. 7 , in electronic component 100D according to a fourth modification, ends 331D of the second grooves 33D on the housing 2 side are not in contact with any of the first grooves 32. Note that Fig. 7 shows electronic component 100D according to the fourth modification from the same perspective as Fig. 2 .

[0095] 7, electronic component 100D of the fourth modification includes circuit element 1, housing 2, and two terminal members 3D. Each of the two terminal members 3D further includes a plurality of first grooves 32 and a plurality of second grooves 33D.

[0096] Ends 331D of the plurality of second grooves 33D on the housing 2 side are not in contact with the plurality of first grooves 32. That is, the plurality of second grooves 33D are formed such that the ends 331D of the plurality of second grooves 33D on the housing 2 side are spaced apart in the first direction D1 from the plurality of first grooves 32. More specifically, the plurality of second grooves 33D are formed such that the ends 331D of the plurality of second grooves 33D on the housing 2 side are spaced apart in the first direction D1 from a first groove 32 among the plurality of first grooves 32 that is provided at a position closest to the tip 301 of the terminal member 3 in the first direction D1.

Note that FIG. 8 shows electronic component 100E according to the fifth modification from the same perspective as FIG. 2 .

[0098] 8, an electronic component 100E of the fifth modification includes a circuit element 1, a housing 2, and two terminal members 3E. Each of the two terminal members 3E further includes a plurality of first grooves 32E and a plurality of second grooves 33E. Hereinafter, the configurations of the plurality of first grooves 32E and the plurality of second grooves 33E, which are similar to the plurality of first grooves 32 and the plurality of second grooves 33 in the above embodiment, will not be described as appropriate.

[0099] Each of the plurality of first groove portions 32E has a first portion 321E and a second portion 322E. In this embodiment, the first portion 321E is a rear portion of each of the plurality of first groove portions 32E, and the second portion 322E is a front portion of each of the plurality of first groove portions 32E.

[0100] The first portion 321E is formed so that the distance from the housing 2 (first side surfaces 23, 24) does not change from the first end (rear end) to the second end (front end). That is, the first portion 321E is formed so as to follow the first side surface 24 of the housing 2 (that is, so as to be parallel to the first side surfaces 23, 24).

[0101] Similarly, the second portion 322E is formed so that the distance from the housing 2 does not change from the third end (front end) to the fourth end (rear end). That is, the second portion 322E is formed so as to follow the first side surface 24 of the housing 2 (that is, so as to be parallel to the first side surfaces 23, 24).

[0102] Each of the multiple first groove portions 32E is divided into a first divided body P1 and a second divided body P2. The first divided body P1 is the first portion 321E described above, and the second divided body P2 is the second portion 322E described above. The conductive member 12 of the circuit element 1 is located between the first divided body P1 and the second divided body P2 in the second direction D2.

That is, the plurality of second grooves 33E are formed such that the ends 331E of the plurality of second grooves 33E on the housing 2 side are spaced apart in the first direction D1 from the plurality of first grooves 32E. More specifically, the plurality of second grooves 33E are formed such that the ends 331E of the plurality of second grooves 33E on the housing 2 side are spaced apart in the first direction D1 from a first groove 32 among the plurality of first grooves 32 that is provided at a position closest to the tip 301 of the terminal member 3E in the first direction D1.

On the other hand, the housing 2-side ends 331E of the multiple second grooves 33E provided in the base 31 of the right terminal member 3E may be in contact with the rightmost first groove 32E of the multiple first grooves 32E.

[0105] (4-6) Other variations Other variations of the above-described embodiment are listed below. The following variations may be realized in appropriate combination.

[0106] In the above embodiment, the number of first groove portions 32 included in each of the two terminal members 3 is plural, but it may be one. That is, the number of first groove portions 32 included in each of the two terminal members 3 needs to be at least one. In short, it is sufficient for each of the two terminal members 3 to have at least one first groove portion 32.

[0107] In the above-described embodiment, each of the two terminal members 3 has a plurality of second groove portions 33, but it may also have one. That is, each of the two terminal members 3 may have at least one second groove portion 33. Furthermore, as in the third modified example, each of the two terminal members 3 does not have to have a second groove portion 33. In short, the second groove portion 33 is not an essential component of each of the two terminal members 3.

The housing (2) accommodates at least a portion of the circuit element (1, 1A, 1B). The terminal members (3, 3A to 3E) are electrically connected to the circuit element (1, 1A, 1B) and protrude from the housing (2) along a first direction (D1). The terminal members (3, 3A to 3E) have grooves formed along a second direction (D2) that intersects with the first direction (D1).

[0109] This embodiment has the advantage that when solder plating is applied to the terminal members (3, 3A to 3E), it is possible to prevent flux from creeping up to the housing (2).

[0110] In the electronic component (100, 100A, 100B, 100D, 100E) of the second aspect, the grooves in the first aspect are first grooves (32, 32A, 32B, 32E). The terminal members (3, 3A, 3B, 3D, 3E) further have second grooves (33, 33D, 33E) that are located between the tip ends (301) of the terminal members (3, 3A, 3B, 3D, 3E) and the first grooves (32, 32A, 32B, 32E) in the first direction (D1) and are formed from the tip ends (301) of the terminal members (3, 3A, 3B, 3D, 3E) along the first direction (D1).

[0111] This embodiment has the advantage that it is easy to make the flux creep up to the target position.

[0112] In the electronic component (100, 100A, 100B) of the third embodiment, in the second embodiment, the end (331) of the second groove (33) on the housing (2) side is in contact with the first groove (32, 32A, 32B).

[0113] This embodiment has the advantage that the flux that reaches the first grooves (32, 32A, 32B) that are in contact with the second grooves (33) can easily enter the first grooves (32, 32A, 32B).

[0114] The electronic component (100, 100A, 100B, 100D, 100E) of the fourth aspect is the electronic component of the second or third aspect, in which the terminal member (3, 3A, 3B, 3D, 3E) has a plurality of second groove portions (33, 33D, 33E) including the second groove portion (33, 33D, 33E).

[0115] This embodiment has the advantage that it becomes easier to make the flux creep up to the target position.

[0116] The electronic component (100, 100A to 100D) of the fifth aspect is any one of the first to fourth aspects, wherein the groove has a first portion (321, 321A, 321B) and a second portion (322, 322A, 322B). The first portion (321, 321A, 321B) has a first end that contacts one of both ends of the terminal member (3, 3A to 3D) in the second direction (D2), and a second end opposite the first end. The distance of the first portion (321, 321A, 321B) from the housing (2) increases in the first direction (D1) from the second end toward the first end. The second portions (322, 322A, 322B) have a third end in contact with one of the ends of the terminal members (3, 3A to 3D) in the second direction (D2), and a fourth end opposite the third end. The second portions (322, 322A, 322B) are gradually spaced apart from the housing (2) in the first direction (D1) from the fourth end toward the third end.

[0117] This embodiment has the advantage that when solder plating is applied to the terminal members (3, 3A to 3D), it is possible to more reliably prevent flux from creeping up to the housing (2).

[0118] The electronic component (100, 100A to 100E) of the sixth aspect is any one of the first to fifth aspects, in which the terminal member (3, 3A to 3E) has a plurality of grooves including a groove.

[0119] This embodiment has the advantage that when solder plating is applied to the terminal members (3, 3A to 3E), it is possible to further prevent flux from creeping up to the housing (2).

[0120] The electronic component (100, 100C to 100E) of the seventh aspect is any one of the first to sixth aspects, in which the circuit element (1) is drawn out from the housing (2) along a first direction (D1) and has a conductive member (12) electrically connected to the terminal members (3, 3C to 3E). The groove portion divides the electronic component into a first divided body (P1) and a second divided body (P2). The conductive member (12) is located between the first divided body (P1) and the second divided body (P2) in the second direction (D2).

[0121] According to this embodiment, even when the conductive member (12) is drawn out along the terminal members (3, 3C to 3E) and electrically connected to the terminal members (3, 3C to 3E), there is an advantage in that when solder plating is applied to the terminal members (3, 3C to 3E), it is possible to prevent flux from creeping up to the housing (2).

[0122] An electronic component (100, 100C to 100E) of an eighth aspect is the electronic component of the seventh aspect, wherein the terminal member (3, 3C to 3E) is provided between the first division (P1) and the second division (P2) along the first direction (D1) and further includes a recess (34) that accommodates the conductive member (12). The first division (P1) and the second division (P2) are in contact with the recess (34).

[0123] According to this embodiment, even when the conductive member (12) is drawn out along the terminal members (3, 3C to 3E) and electrically connected to the terminal members (3, 3A to 3E), there is an advantage that the flux can be more effectively prevented from creeping up to the housing (2) when solder plating is applied to the terminal members (3, 3C to 3E).
