Description

[Technical field]

[0001] The present invention relates to electronic devices and cables. [Background technology]

[0002] 2. Description of the Related Art There are known electronic devices, such as motors (see, for example, Patent Document 1), that have a structure in which conductor wires drawn from a cable are connected to a substrate. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2002-374655 A Summary of the Invention [Problem to be solved by the invention]

[0004] A full flat cable is soldered to the motor board in Patent Document 1, but there is a concern that the full flat cable may be displaced or twisted, causing breaks in the soldered portion. One possible solution to this problem is to fix the full flat cable to the motor board with an adhesive, but the adhesive may be repelled by the surface of the full flat cable, making it difficult to obtain sufficient adhesive strength. This may shorten the life of the cable fixed to the board.

[0005] The present disclosure has been made in consideration of the above-mentioned problems, and its purpose is to improve the fixing life of a cable to a board in an electronic device having a structure in which a conductor drawn from a cable is connected to the board. [Means for solving the problem]

[0006] An electronic device according to an embodiment of the present disclosure includes a substrate and a cable. The substrate extends in a first direction and a second direction intersecting the first direction. One end of the cable is disposed on one end surface of the substrate in a third direction perpendicular to the first direction and the second direction. The cable has a conductor, an insulating portion, and an opening. The conductor extends in the first direction at one end of the cable. The insulating portion covers the conductor. The opening is disposed on the other end surface of the insulating portion in the third direction and opens at least to the other side in the third direction. The one end of the conductor in the first direction is a conductor end drawn out from the insulating portion to one side in the first direction and is connected to the one end surface of the substrate in the third direction. At least a portion of the adhesive disposed on the one end surface of the substrate in the third direction is disposed within the opening.

[0007] Also, an electronic device according to another aspect of the present disclosure includes a substrate and a cable.

One end of the cable is disposed on one end surface of the substrate in a third direction perpendicular to the first direction and the second direction. The cable has a conductor, an insulating portion, and a bottom plate portion. The conductor extends in the first direction at one end of the cable. The insulating portion covers the conductor. At one end of the cable, the bottom plate portion protrudes from one end of the insulating portion in the first direction to one side in the first direction and extends in the second direction. The one end of the conductor in the first direction is a conductor end portion drawn out from the insulating portion to one side in the first direction, and is connected to one end surface of the substrate in the third direction.

[0008] One end of a cable according to one embodiment of the present disclosure is disposed on one end surface of a substrate in a third direction. The substrate extends in a first direction and a second direction intersecting the first direction. The third direction is perpendicular to the first direction and the second direction. The cable includes a conductor, an insulating portion, and an opening. The conductor extends in the first direction at one end of the cable. The insulating portion covers the conductor.

The one end of the conductor in the first direction is a conductor end drawn out from the insulating portion to one side in the first direction and is connected to the one end surface of the substrate in the third direction. At least a part of the adhesive disposed on the one end surface of the substrate in the third direction is disposed in the opening.

[0009] Moreover, one end of a cable according to another aspect of the present disclosure is disposed on one end surface of the substrate in the third direction. The substrate extends in the first direction and the second direction intersecting with the first direction. The third direction is perpendicular to the first direction and the second direction. The cable includes a conductor, an insulating portion, and a bottom plate portion. The conductor extends in the first direction at one end of the cable. The insulating portion covers the conductor. The bottom plate portion protrudes from one end of the insulating portion in the first direction to one side in the first direction at one end of the cable and extends in the second direction. The one end of the conductor in the first direction is a conductor end portion drawn out from the insulating portion to one side in the first direction, and is connected to one end surface of the substrate in the third direction.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] <1. Embodiment> Hereinafter, exemplary embodiments of the present disclosure will be described with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference characters, and the description thereof may not be repeated.

[0014] In the embodiment, for ease of understanding, a first direction D1, a second direction D2, and a third direction D3 that intersect with each other are appropriately used. Of the first direction D1, one direction is called "first direction one side D1a" and the other direction is called "first direction other side D1b". Of the second direction D2, one direction is called "second direction one side D2a" and the other direction is called "second direction other side D2b". Of the third direction D3, one direction is called "third direction one side D3a" and the other direction is called "third direction other side D3b".

[0015] In addition, in the positional relationship between any one of a direction, a line, and a plane and any other, "parallel" includes not only a state in which the two do not intersect at all no matter how far they are extended, but also a state in which they are substantially parallel. Furthermore, "perpendicular" and "orthogonal" each include not only a state in which the two intersect at 90 degrees, but also a state in which they are substantially perpendicular and a state in which they are substantially orthogonal, respectively. In other words, "parallel," "perpendicular," and "orthogonal" each include a state in which there is an angle deviation in the positional relationship between the two to an extent that does not deviate from the gist of the present invention.

[0016] Note that these are names used merely for the purpose of explanation, and are not intended to limit the actual positional relationships, directions, names, and the like.

[0017] Fig. 1 is a schematic diagram showing a structure of an electronic device 100 according to an embodiment in which a conductor 1 drawn from a cable 3 is connected to a substrate 4. Fig. 2 is a cross-sectional view taken along the dashed dotted line II-II in Fig. 1.

[0018] The electronic device 100 is, for example, a motor or a fan motor. However, this example does not exclude a configuration in which the electronic device 100 is a device other than a motor or a fan motor. The electronic device 100 may be any device having a structure in which a conductor 1 drawn from a cable 3 is connected to a substrate 4.

[0019] As shown in FIG. 1, the electronic device 100 includes a cable 3 and a substrate 4. The substrate 4 extends in a first direction D1 and a second direction D2. The second direction D2 intersects with the first direction D1 and is perpendicular to the first direction D1 in this embodiment. One end of the cable 3 is disposed on an end face of the substrate 4 on one side of the third direction D3a. The third direction D3 is perpendicular to the first direction D1 and the second direction D2 in this embodiment. In other words, the substrate 4 is disposed on the other side of the third direction D3b with respect to the cable 3. The substrate 4 has a thickness in the third direction D3.

[0020] The cable 3 has a conductor 1 and an insulating portion 2. The conductor 1 extends in a first direction D1 at one end of the cable 3. The insulating portion 2 insulates the conductor 1. There are multiple conductors 1, and they are arranged in a second direction D2 that intersects with the first direction D1. That is, the multiple conductors 1 are arranged in parallel. Note that, although there are three conductors 1 in this embodiment, this is not limited to this example. There may be a single conductor 1, or a multiple number other than three.

[0021] An end of the conductor 1 on the first direction D1a side is a conductor end 5 drawn out from the insulating part 2 on the first direction D1a side, and is connected to an end face on the third direction D3a side of the substrate 4. In other words, the cable 3 includes the conductor end 5.

[0022] At least the end of the insulating part 2 in the second direction D2 is an edge part 6 that is flat in the third direction D3. For example, the insulating part 2 has an edge part 6 in at least a part of each of both ends in the second direction D2. The edge part 6 is flat in the third direction D3. Here, the edge part 6 being flat in the third direction D3 means that the width of the edge part 6 in the third direction D3 is equal to or smaller than the width of the edge part 6 in the first direction D1, and the width of the edge part 6 in the third direction D3 is equal to or smaller than the width of the edge part 6 in the second direction D2.

[0023] Here, in this embodiment, the conductor 1 is a flat conductor. The insulating portion 2 is two insulating tapes arranged parallel to each other in the third direction D3, for example, a PVC resin tape. A plurality of flat conductors (conductors 1) are arranged parallel to each other at a fixed interval in the second direction D2 between the two insulating tapes. Both ends of the flat conductor (conductor 1) are exposed from the ends of the two insulating tapes (insulating portions 2) over a fixed length to form connection terminal portions. The two insulating tapes are integrated by fusion. Note that the edge portion 6 only needs to be located on both sides of the conductor 1 in the second direction D2, and does not necessarily have to be located at the outer edge portion of the insulating portion 2.

[0024] Here, the conductor end 5 is connected by soldering to a land portion located on the end face of the substrate 4 on one side D3a in the third direction. However, the means for connecting the conductor end 5 to the land portion is not limited to soldering. For example, a conductive paste such as silver paste may be used as the external connection means.

[0025] The cable 3 also has an opening 7. The opening 7 is arranged on the end face of the insulating part 2 on the other side in the third direction D3b, and opens at least on the other side in the third direction D3b. The opening 7 is arranged in the edge part 6. In this embodiment, as shown in FIG. 1, the opening 7 is arranged in the edge parts 6 at both ends in the second direction D2, and penetrates the insulating part 2 (the edge part 6) in the third direction D3. That is, the edge part 6 has the opening 7. In other words, the opening 7 is a recess recessed inward in the second direction D2 from the outer end part in the second direction D2 of the insulating part 2 (the edge part 6).

[0026] The insulating portion 2 of the cable 3 is disposed on the end face of the substrate 4 on one side D3a in the third direction using an adhesive 8. For example, at least a part of the adhesive 8 disposed on the end face of the substrate 4 on one side D3a in the third direction is disposed (filled) in the opening 7. The adhesive 8 may be, for example, a UV adhesive, an acrylic adhesive, an epoxy adhesive, or a urethane adhesive. It may also be a coating agent exhibiting adhesive properties, such as Humiseal. However, this example does not exclude a configuration in which the adhesive 8 is other than these.

[0027] In this way, the adhesive 8 disposed in the opening 7 positions the cable 3 with respect to the board 4, and the displacement or twisting of the cable 3 is suppressed. As a result, it is possible to suppress breakage of the conductor end 5 caused by the displacement or twisting of the cable 3. Therefore, the fixing life of the cable 3 to the board 4 can be improved.

[0028] Furthermore, when attempting to fix cable 3 to substrate 4 with adhesive 8, there is a concern that sufficient adhesive strength may not be obtained if the surface of cable 3 and adhesive 8 are not compatible, such as the adhesive 8 being repelled by the surface of cable 3. By having edge 6 have opening 7 and at least a portion of adhesive 8 arranged on the end face on one side D3a in the third direction of substrate 4 being arranged within opening 7, it becomes possible to position cable 3 with respect to substrate 4 and suppress displacement or twisting of cable 3 regardless of the compatibility between the surface of cable 3 and adhesive 8.

[0029] At this time, part of the adhesive 8 may be disposed on the end face on the one side in the third direction D3a of the insulating part 2. For example, part of the adhesive 8 is disposed within the opening 7. On the other hand, preferably, another part of the adhesive 8 is disposed closer to the one side in the third direction D3a than the end face on the one side in the third direction D3a of the insulating part 2, and covers the end face on the one side in the third direction D3a of the insulating part 2 along at least part of the outer edge of the opening 7 when viewed from the third direction D3.

[0030] Furthermore, as shown in FIG. 2, the width d1 in the third direction D3 of the portion of the adhesive 8 covering the end face on one side in the third direction D3a of the insulating portion 2 is equal to or greater than the width d2 of the opening 7 in the third direction D3.

[0031] For example, at least a part of the adhesive 8 is disposed on the other third direction D3b side of the cable 3 on at least a part of the periphery of the opening 7. In other words, a part of the adhesive 8 disposed on the end face on the one third direction D3a side of the substrate 4 within the opening 7 rides up on the one third direction D3a side of the cable 3 (the insulating part 2 thereof) on at least a part of the periphery of the opening 7. At this time, the cable 3 can be more reliably positioned with respect to the substrate 4, and displacement, twisting, and the like of the cable 3 are reliably suppressed.

[0032] However, this example does not exclude a configuration in which a part of the adhesive 8 is not disposed on the end face of the insulating part 2 on the one side of the third direction D3a. Regardless of whether at least a part of the adhesive 8 is disposed on the one side of the third direction D3a of the cable 3 in at least a part of the periphery of the opening 7, the cable 3 is positioned with respect to the board 4, and the displacement and twisting of the cable 3 are suppressed. If at least a part of the adhesive 8 is not disposed on the other side of the third direction D3b of the cable 3 in at least a part of the periphery of the opening 7, when the cable 3 is displaced or twisted, the periphery of the opening 7 of the cable 3 comes into contact with the adhesive 8 disposed in the opening 7, and the movement is restricted. Even if at least a part of the adhesive 8 is disposed on the other side of the third direction D3b of the cable 3 in at least a part of the periphery of the opening 7, when the cable 3 is displaced or twisted, the movement of the periphery of the opening 7 of the cable 3 is restricted by the adhesive 8 disposed in the opening 7.

[0033] In other words, the opening 7 provided in the cable 3 plays the role of a recess. Meanwhile, the adhesive 8 disposed within the opening 7 plays the role of a protrusion. That is, the protrusion disposed within the recess restricts the movement of the recess. In this way, it is not easy to provide a protrusion on the substrate 4 that engages with the recess provided in the cable 3 to restrict the movement of the cable 3. However, by disposing the adhesive 8, for example by application, on the end face of the substrate 4 on the one side of the third direction D3a so that at least a part of the adhesive 8 disposed on the end face of the substrate 4 on the one side of the third direction D3a is disposed within the opening 7, the adhesive 8 hardens in accordance with the shape of the opening 7, and therefore a protrusion that engages with the recess of the opening 7 (i.e., a fitting structure of the protrusion with the recess) can be easily provided.

[0034] Also, preferably, an adhesive 8 is interposed between the cable 3 and the substrate 4 in the third direction D3. For example, as shown in Fig. 2, in at least a part of the outer edge of the end of the opening 7 on the other side of the third direction D3b, the adhesive 8 is disposed between the end face of the cable 3 (its insulating part 2) on the other side of the third direction D3b and the end face of the substrate 4 on the one side of the third direction D3a. This can improve the engagement strength of the protrusion (adhesive 8 in the opening 7) with the recess (opening 7) described above (i.e., the engagement strength of the protrusion with the recess).

[0035] In FIG. 1, the opening 7 is located at the outer end of the edge 6 in the second direction D2. That is, the opening 7 opens at the end of the edge 6 in the second direction D2. However, this is not limited to the example, and the opening 7 may be spaced inward in the second direction D2 from the outer end of the insulating part 2 (edge ​​6 thereof) in the second direction D2 when viewed from the third direction D3. In other words, at least one of the openings 7 may be disposed between the outer end of the insulating part 2 (edge ​​6 thereof) in the second direction D2 and the conductor 1 with a gap therebetween when viewed from the third direction D3.

[0036] Moreover, the opening 7 has a hole shape whose periphery is bordered by the insulating part 2, and is arranged singly in each edge part 6. The shape of the opening 7 is rectangular in FIG. 1 when viewed from the third direction D3. However, the shape of the opening 7 when viewed from the third direction D3 is not limited to this example, and may be other than rectangular, for example, an n-sided shape such as a triangle (n is a positive integer of 3 or more), a circle, a semicircle, or the like. Also, at least one edge part 6 may have a plurality of openings 7. Furthermore, at least one of the plurality of openings 7 may be located at the outer end of the edge part 6 in the second direction D2. That is, all of the openings 7 may be arranged at the outer end of the edge part 6 in the second direction D2. Alternatively, some of the plurality of openings 7 may be arranged at the outer end of the edge part 6 in the second direction D2, and the other part may be arranged away from the outer end of the edge part 6 in the second direction D2 toward the inward side of the second direction D2.

[0037] At least one of the openings 7 is located at an end of the edge 6 in the second direction D2, so that both ends of the cable 3 in the second direction D2 can be positioned with respect to the substrate 4, thereby more reliably suppressing misalignment and twisting of the cable 3. Furthermore, the work of placing the adhesive 8 on the end face on the one side of the third direction D3a of the substrate 4 around the cable 3 and the work of placing the adhesive 8 on the end face on the one side of the third direction D3a of the substrate 4 within the opening 7 can be performed consecutively, thereby improving the workability of placing the adhesive 8.

[0038] In this case, at least a part of the adhesive 8 may be disposed on the one side in the third direction D3a of the cable 3 in at least a part of the outer end of the insulating part 2 in the second direction D2. In other words, a part of the adhesive 8 disposed on the end face on the one side in the third direction D3a of the substrate 4 around the cable 3 rides up on the one side in the third direction D3a of the cable 3 in at least a part of the outer end of the insulating part 2 in the second direction D2. As a result, the cable 3 can be more reliably positioned with respect to the substrate 4, and displacement, twisting, and the like of the cable 3 are more reliably suppressed.

[0039] Preferably, the width W1 of the opening 7 in the first direction D1 is equal to or larger than the width W0 of the conductor 1 in the second direction D2 when viewed from the third direction D3. For example, the maximum value of the width W1 of the opening 7 is equal to or larger than the minimum value of the width W0 of the conductor 1 when viewed from the third direction D3. Also, preferably, the width W2 of the opening 7 in the second direction D2 is equal to or larger than the width W0 of the conductor 1 in the second direction D2 when viewed from the third direction D3. For example, the maximum value of the width W2 of the opening 7 is equal to or larger than the minimum value of the width W0 of the conductor 1 when viewed from the third direction D3. Here, the width W0 of the conductor 1 in the second direction D2 is defined at a position where the conductor 1 is drawn out from the insulating portion 2 to one side in the first direction D1, in other words, it is the width in the second direction D2 at the end of the conductor end 5 on the other side in the first direction D1.

[0040] In this way, opening 7 can be made larger, so that adhesive 8 placed within opening 7 can more reliably position cable 3 relative to substrate 4, and displacement or twisting of cable 3 can be more reliably prevented.

[0041] Preferably, a width W3 in the first direction D1 between the end of the conductor end 5 on the other side in the first direction D1b and the end of the opening 7 on the one side in the first direction D1a is equal to or greater than a width W0 in the second direction D2 of the conductor 1. For example, the minimum value of the width W3 is equal to or greater than the minimum value of the width W0 of the conductor 1. This can prevent electronic components 9 arranged around the conductor end 5 connected to the board 4 from impairing the workability of arranging the adhesive 8.

[0042] Also, preferably, a member other than the adhesive 8 may be used as a means for fixing the insulating portion 2 to the substrate 4. For example, the cable 3 further includes a fixing member 31. The fixing member 31 fixes the insulating portion 2 to the end face of the substrate 4 on the one side in the third direction D3a. For example, the fixing member 31 is disposed between the insulating portion 2 and the substrate 4. Also, in FIG. 1, the fixing member 31 is disposed between the openings 7 disposed in the edge portions 6 as viewed from the third direction D3, and in particular overlaps with the conductor 1 as viewed from the third direction D3. The fixing member 31 is not particularly limited, and for example, a double-sided tape is used. However, without being limited to this example, the fixing member 31 may be an adhesive member that is the same as or different from the adhesive 8.

[0043] When a force toward at least one side of the third direction D3a acts on the cable 3 due to the arrangement of the fixing member 31, the fixing member 31 makes it difficult for the insulating part 2 to separate from the board 4. Therefore, the conductor 1 (particularly the conductor end 5) becomes difficult to bend, and the fixing life of the cable 3 to the board 4 can be improved.

[0044] However, this example does not exclude a configuration in which the fixing member 31 is not disposed between the openings 7, and does not exclude a configuration in which the fixing member 31 does not overlap the conductor 1 when viewed from the third direction D3. In addition, the above example does not exclude a configuration in which the cable 3 disposed at each edge 6 does not include the fixing member 31.

[0045] <1-1. First to third modified examples of the embodiment> Next, a first modification to a third modification of the embodiment will be described with reference to FIG. 3A to FIG. 5. FIG. 3A is a schematic diagram showing a structural example of the electronic device 100 according to the first modification, in which the conductor 1 drawn from the cable 3 is connected to the board 4. FIG. 3B is a schematic diagram showing another structural example of the electronic device 100 according to the first modification, in which the conductor 1 drawn from the cable 3 is connected to the board 4. FIG. 4 is a schematic diagram showing a structural example of the electronic device 100 according to the second modification, in which the conductor 1 drawn from the cable 3 is connected to the board 4. FIG. 5 is a schematic diagram showing a structural example of the electronic device 100 according to the third modification, in which the conductor 1 drawn from the cable 3 is connected to the board 4. In each modification, a configuration different from the embodiment and other modifications will be described. In each modification, the same reference numerals are given to components similar to those in the embodiment and other modifications, and their description may be omitted. In addition, the embodiment and its first modification to third modification can be implemented in any combination as long as no particular contradiction occurs.

[0046] <1-1-1. First modified example> In the above embodiment, the opening 7 is provided as a through hole penetrating the edge portion 6 in the third direction D3, but in the first modified example shown in FIG. 3A and FIG. 3B, a cut 10 is provided in a part of the edge portion 6, and a part of the edge portion 6 is folded at a crease 11 to be disposed in a direction away from the substrate 4. In the above embodiment, at least a part of the adhesive 8 is disposed inside the opening 7, but in the first modified example shown in FIG. 3A and FIG. 3B, at least a part of the adhesive 8 is disposed between the part of the edge portion 6 disposed in a direction away from the substrate 4 and the substrate 4 by the cut 10 and the crease 11. In other words, the opening 7 may be formed by a through hole as in the embodiment, or may be formed by the cut 10 and the crease 11 as in the first modified example. At this time, the part of the edge portion 6 disposed in a direction away from the substrate 4 covers at least a part of the adhesive 8 disposed between the substrate 4 and the part of the edge portion 6, so that the adhesive 8 can be prevented from peeling off from the substrate 4.

[0047] Here, as shown in Fig. 3A, two incisions 10 extending in the second direction D2 may be provided, and the portion between the incisions 10 may be folded in the second direction D2, or as shown in Fig. 3B, an incision 10 extending in the first direction D1 and an incision 10 extending in the second direction D2 may be provided, and the portion bordered by the incisions 10 may be folded in the first direction D1. Note that the incisions 10 and the folds 11 are not limited to those illustrated in Figs. 3A and 3B.

[0048] <1-1-2. Second modified example> In the second modified example, as shown in FIG. 4, the cable 3 further includes a bottom plate portion 21. The bottom plate portion 21 protrudes in the first direction D1a from an end portion of the insulating portion 2 on the first direction D1a side at one end of the cable 3, and extends in the second direction D2. The width of the bottom plate portion 21 in the third direction D3 is smaller than the width of the insulating portion 2 in the third direction D3. Therefore, the bottom plate portion 21 has higher flexibility than the insulating portion 2. Note that the width of the bottom plate portion 21 in the second direction D2 is the same as the width of the insulating portion 2 in the second direction D2 in FIG. 4. However, this is not limited to the example, and the width of the bottom plate portion 21 in the second direction D2 may be smaller or larger than the width of the insulating portion 2 in the second direction D2 in FIG. 4.

[0049] In this way, when a force toward at least one side of the third direction D3a acts on the cable 3, the number of locations at which the conductor end 5 is easily bent can be increased compared to a configuration in which the cable 3 does not have a bottom plate portion 21.

[0050] For example, in a configuration in which the cable 3 does not have a bottom plate portion 21, the conductor end 5 is likely to bend significantly relative to the substrate 4 at a position in the first direction D1 that is the same as the end of the insulating portion 2 on the first direction D1a side. On the other hand, in the above-mentioned configuration, the conductor end 5 is likely to bend relative to the substrate 4 at at least two positions, including a position in the first direction D1 that is the same as the end of the bottom plate portion 21 on the first direction D1a side, and a position in the first direction D1 that is the same as the end of the insulating portion 2 on the first direction D1a side. This makes it possible to reduce the degree of bending at each of the positions that are likely to bend. This makes it possible to suppress the risk of the conductor 1 (particularly the conductor end 5) being weakened or broken due to bending, thereby improving the fixing life of the cable 3 to the substrate 4.

[0051] In FIG. 4, at least a part of the end face of the bottom plate portion 21 on the other third direction D3b side contacts the end face of the substrate 4 on the one third direction D3a side. For example, in FIG. 4, the bottom plate portion 21 protrudes from the end of the insulating portion 2 on the other third direction D3b side. In this way, the part of the end face of the bottom plate portion 21 on the other first direction D1b side on the other third direction D3b side can be easily brought into contact with the end face of the substrate 4 on the one third direction D3a side. Therefore, the contact area between the bottom plate portion 21 and the substrate 4 can be increased, and the bottom plate portion 21 can be bent over a wider range in the first direction D1. Therefore, even if the above-mentioned force acts on the cable 3, the degree of bending at the bottom plate portion 21 can be further reduced.

[0052] However, without being limited to the above example, at least a part of the end face of the bottom plate portion 21 on the other side of the third direction D3b may not be in contact with the end face of the substrate 4 on the one side of the third direction D3a, and may be bonded to the end face of the substrate 4 with, for example, an adhesive member or the like. Furthermore, the above example does not exclude a configuration in which the bottom plate portion 21 does not protrude from the part of the insulating portion 2 on the other side of the third direction D3b at the end of the insulating portion 2 on the one side of the first direction D1a. For example, at the end of the insulating portion 2 on the one side of the first direction D1a, the bottom plate portion 21 may protrude from the part of the insulating portion 2 on the one side of the third direction D3a, or may protrude from the part between both ends of the insulating portion 2 in the third direction D3. Even in these cases, the fixing life of the cable 3 to the substrate 4 can be improved, as in FIG. 4.

[0053] In FIG. 4, the bottom plate portion 21 is disposed between the conductor 1 (particularly the conductor end portion 5) and the board 4 in the third direction D3. That is, the bottom plate portion 21 is disposed between the portion of the conductor end portion 5 on the other first direction D1b side and the board 4 (the end face on the one third direction D3a side). However, without being limited to this example, the bottom plate portion 21 does not have to be disposed between the conductor 1 and the board 4 in the third direction D3, and may be disposed, for example, on the one third direction D3a side of at least one conductor 1 (particularly its conductor end portion 5). Even in this case, the fixing life of the cable 3 to the board 4 can be improved, as in FIG. 4.

[0054] <1-1-3.Third modified example> In the third modified example, as shown in Fig. 5, the cable 3 further has a protruding portion 22. The protruding portion 22 protrudes from an end of the insulating portion 2 in the first direction D1 toward one side of the first direction D1a at one end of the cable 3. Note that in Fig. 5, there is a pair of protruding portions 22, each protruding from both ends of the insulating portion 2 in the second direction D2 when viewed from the third direction D3. However, this is not limited to the example, and the protruding portion 22 may protrude only from either the end of the insulating portion 2 on the one side of the second direction D2a or the end of the insulating portion 2 on the other side of the second direction D2b.

[0055] The position of the end of the protruding portion 22 on the first direction D1a side is closer to the first direction other D1b side than the end of the conductor end 5 on the first direction D1a side, and preferably different from the end of the bottom plate portion 21 on the first direction D1a side in the first direction D1. More preferably, the position of the end of at least one protruding portion 22 on the first direction D1a side is closer to the first direction D1a side than the end of the bottom plate portion 21 on the first direction D1a side. However, this is not limited to the example, and the position of the end of at least one protruding portion 22 on the first direction D1a side may be closer to the first direction other D1b side than the end of the bottom plate portion 21 on the first direction D1a side.

[0056] This can further increase the number of locations where the conductor end 5 of the cable 3 is easily bent. For example, the conductor end 5 is easily bent at at least three locations relative to the substrate 4, including a position in the first direction D1 that is the same as the end on the first direction D1a side of the bottom plate portion 21, a position in the first direction D1 that is the same as the end on the first direction D1a side of the protruding plate portion 22, and a position in the first direction D1 that is the same as the end on the first direction D1a side of the insulating portion 2. This can further reduce the degree of bending at each of the easily bent locations. This can further improve the fixing life of the cable 3 to the substrate 4.

[0057] For example, the protruding portion 22 protrudes from the end portion of the insulating portion 2 on the other third direction D3b side. This allows the portion of the end face of the protruding portion 22 on the other first direction D1b side to easily come into contact with the end face of the substrate 4 on the one third direction D3a side. This increases the contact area between the protruding portion 22 and the substrate 4, allowing the protruding portion 22 to bend over a wider range in the first direction D1. This allows the degree of bending at the protruding portion 22 to be further reduced even if the above-mentioned force acts on the cable 3.

[0058] However, this example does not exclude a configuration in which at least one protruding portion 22 does not protrude from an end portion on the other third direction D3b side of the insulating portion 2. For example, at an end portion on the one first direction D1a side of the insulating portion 2, the protruding portion 22 may protrude from a portion on the one third direction D3a side of the insulating portion 2, or may protrude from a portion between both ends in the third direction D3 of the insulating portion 2. Even in these cases, the fixing life of the cable 3 to the board 4 can be similarly improved.

[0059] 5, the cable 3 has a bottom plate portion 21. At least one protrusion 22 may be integral with the bottom plate portion 21 and may be connected to the bottom plate portion 21 in the second direction D2. Alternatively, at least one protrusion 22 may not be integral with the bottom plate portion 21 and may not be connected to the bottom plate portion 21 in the second direction D2.

[0060] However, this example does not exclude a configuration in which the cable 3 does not have the bottom plate portion 21. For example, even if the bottom plate portion 21 is omitted in the third modified example, the conductor end portion 5 can be easily bent at least in two places due to the protruding portion 22, as in the second modified example. Therefore, the effect of improving the fixing life of the cable 3 to the board 4 can be obtained.
