[0003] Patent Document 1: Japanese Patent Application Publication No. 2002-374655 Summary of the invention

[0004] A full flat cable is soldered to the motor substrate in Patent Document 1, but the full flat cable may break at the soldered portion due to deviation or twisting of the full flat cable. As a countermeasure, for example, it is considered to fix the full flat cable to the motor substrate with an adhesive, but the adhesive is repelled from the surface of the full flat cable, so sufficient bonding strength may not be obtained. Therefore, the fixing life of the cable to the substrate may be shortened.

[0005] The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to improve the fixing life of a cable to a substrate in an electronic device having a structure in which a lead wire led out from a cable is connected to a substrate.

In addition, 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 comprises a conductor, an insulating portion, and an opening. The conductor extends along the first direction at one end of the cable. The insulating portion covers the conductor. The opening is arranged on the other end face of the insulating portion in the third direction, and is open at least on the other side of the third direction. One side end of the conductor in the first direction is an end of the conductor drawn out from the insulating portion to one side of the first direction, and is connected to one side end face of the substrate in the third direction.

The bottom plate portion protrudes from an end portion of the insulating portion on one side in the first direction at one end of the cable to one side of the first direction and extends in the second direction. An end portion of the conductor on one side in the first direction is an end portion of the conductor drawn out from the insulating portion to one side in the first direction, and is connected to an end face of the substrate on one side in the third direction.

DETAILED DESCRIPTION

[0013] <1. Implementation Method> Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings. In addition, in the drawings, the same reference numerals are given to the same or corresponding parts, and their description may not be repeated.

[0014] In the embodiment, for easy understanding, the first direction D1, the second direction D2, and the third direction D3 that intersect each other are appropriately used. In addition, one direction in the first direction D1 is referred to as "the first direction one direction D1a", and the other direction is referred to as "the first direction other direction D1b". One direction in the second direction D2 is referred to as "the second direction one direction D2a", and the other direction is referred to as "the second direction other direction D2b". One direction in the third direction D3 is referred to as "the third direction one direction D3a", and the other direction is referred to as "the third direction other direction D3b".

[0015] In addition, in the positional relationship between any one of the orientations, lines and planes and any other one, "parallel" includes not only a state where the two do not intersect at all wherever they extend, but also a state where they are substantially parallel. In addition, "perpendicular" and "orthogonal" include not only a state where the two intersect each other at 90 degrees, but also a state where they are substantially perpendicular and a state where they are substantially orthogonal. That is, "parallel", "perpendicular" and "orthogonal" include a state where the positional relationship between the two is angularly offset to a degree that does not deviate from the main purpose of the present invention.

[0016] In addition, these names are used only for explanation, and are not intended to limit actual positional relationships, directions, names, etc.

[0017] Figure 1 1 is a schematic diagram showing a structure in which a lead wire 1 drawn out from a cable 3 is connected to a substrate 4 in an electronic device 100 according to the embodiment. Figure 2 is along Figure 1 Cross-sectional view along the dotted line II-II.

[0018] The electronic device 100 is, for example, a motor or a fan motor. However, this example does not exclude a configuration where the electronic device 100 is a device other than a motor or a fan motor. The electronic device 100 may be any device as long as it has a structure that connects the lead wire 1 drawn from the cable 3 to the substrate 4 .

[0019] like Figure 1 As shown, 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. In addition, the second direction D2 intersects the first direction D1 and is perpendicular to the first direction D1 in this embodiment. One end of the cable 3 is arranged on an end surface of the substrate 4 on the side of one third direction D3a. In addition, in this embodiment, the third direction D3 is perpendicular to the first direction D1 and the second direction D2. In other words, the substrate 4 is arranged on the side of the other third direction D3b relative to the cable 3. The substrate 4 has a thickness in the third direction D3.

[0020] The cable 3 includes a conductor 1 and an insulating portion 2. The conductor 1 extends along a first direction D1 at one end of the cable 3. The insulating portion 2 insulates the conductor 1. There are a plurality of conductors 1, which are arranged in a second direction D2 intersecting the first direction D1. That is, a plurality of conductors 1 are arranged in parallel. In addition, the conductors 1 are three in this embodiment, but are not limited to this example. The conductors 1 may be single or may be multiple other than three.

[0021] The end of the conductor 1 on the first direction D1a side is a conductor end 5 drawn out from the insulating portion 2 toward the first direction D1a side, and connected to the end surface on the third direction D3a side of the substrate 4. That is, the cable 3 includes the conductor end 5.

[0022] At least the end of the insulating portion 2 in the second direction D2 is an edge portion 6 that is flat in the third direction D3. For example, the insulating portion 2 has an edge portion 6 at least in part of each of the two ends in the second direction D2. The edge portion 6 is flat in the third direction D3. Here, the edge portion 6 is flat in the third direction D3, which means that the width of the edge portion 6 in the third direction D3 is less than the width of the edge portion 6 in the first direction D1, and the width of the edge portion 6 in the third direction D3 is less than the width of the edge portion 6 in the second direction D2.

[0023] Here, in the present embodiment, the conductor 1 is a flat conductor. The insulating portion 2 is two insulating tapes arranged in parallel and opposite to each other in the third direction D3, for example, a PVC resin tape. Between the two insulating tapes, a plurality of flat conductors (conductors 1) are arranged in parallel at a certain interval in the second direction D2. Both ends of the flat conductor (conductor 1) are exposed from the ends of the two insulating tapes (insulating portion 2) over a certain length to form a connection terminal portion. The two insulating tapes are integrated by welding. In addition, the edge portion 6 only needs to be located on both sides of the second direction D2 relative to the conductor 1, and does not necessarily need to be located at the outer edge of the insulating portion 2.

[0024] Here, the wire end 5 is connected to the pad portion of the end surface located on the third direction one side D3a of the substrate 4 by soldering. However, the connection method of the wire end 5 to the pad portion is not limited to soldering. For example, conductive paste such as silver paste can be used for the external connection device.

[0025] In addition, the cable 3 has an opening 7. The opening 7 is arranged on the end surface of the insulating portion 2 on the other side D3b of the third direction, and is open at least on the other side D3b of the third direction. The opening 7 is arranged in the edge portion 6. In this embodiment, as shown in FIG. Figure 1 As shown, the openings 7 are respectively arranged at the edge portions 6 at both ends in the second direction D2, and penetrate the insulating portion 2 (the edge portion 6) in the third direction D3. That is, the edge portion 6 has the opening 7. In other words, the opening 7 is a concave portion that is recessed from the outer end of the insulating portion 2 (the edge portion 6) in the second direction D2 to the inner side in the second direction D2.

[0026] The insulating portion 2 of the cable 3 is arranged on the end face of the substrate 4 on the side of the third direction D3a using an adhesive 8. For example, at least a portion of the adhesive 8 arranged on the end face of the substrate 4 on the side of the third direction D3a is arranged (filled) in the opening 7. In addition, the adhesive 8 can be, for example, a UV adhesive, or an acrylic adhesive, an epoxy adhesive, or a polyurethane adhesive. In addition, it can also be a coating agent showing adhesiveness such as HumiSeal (Japanese: ヒューミシール). However, this example does not exclude that the adhesive 8 has a structure other than these.

[0027] Thus, the adhesive 8 disposed in the opening 7 positions the cable 3 relative to the substrate 4, and suppresses the displacement or twisting of the cable 3. As a result, it is possible to suppress the breakage of the lead end 5 due to the displacement or twisting of the cable 3. Therefore, the fixing life of the cable 3 relative to the substrate 4 can be improved.

[0028] In addition, when the cable 3 is to be fixed to the substrate 4 using the adhesive 8, sufficient bonding strength may not be obtained if the surface of the cable 3 repels the adhesive 8 or the compatibility between the surface of the cable 3 and the adhesive 8 is poor. The edge portion 6 has an opening 7, and at least a portion of the adhesive 8 disposed on the end surface of the substrate 4 on the third direction one side D3a side is disposed in the opening 7. Thus, regardless of the compatibility between the surface of the cable 3 and the adhesive 8, the cable 3 can be positioned relative to the substrate 4, and the displacement and distortion of the cable 3 can be suppressed.

[0029] At this time, a part of the adhesive 8 may also be arranged on the end face on the side D3a of the third direction of the insulating portion 2. For example, a part of the adhesive 8 is provided in the opening 7. On the other hand, it is preferred that another part of the adhesive 8 is arranged at a position closer to the side D3a of the third direction than the end face on the side D3a of the third direction of the insulating portion 2, and at least a part of the outer edge of the opening 7 covers the end face on the side D3a of the third direction of the insulating portion 2 as viewed from the third direction D3.

[0030] Moreover, if Figure 2 As shown, the width d1 in the third direction D3 of the portion of the adhesive 8 covering the end surface of the insulating portion 2 on the third direction one side D3a is greater than the width d2 of the opening 7 in the third direction D3.

[0031] For example, at least a portion of the adhesive 8 is disposed on the other side D3b of the third direction of the cable 3 at least in a portion of the periphery of the opening 7. In other words, a portion of the adhesive 8 disposed on the end surface on the one side D3a of the third direction of the substrate 4 in the opening 7 is placed on the one side D3a of the third direction of the cable 3 (the insulating portion 2) at least in a portion of the periphery of the opening 7. In this case, the cable 3 can be more reliably positioned relative to the substrate 4, and the displacement, twisting, etc. of the cable 3 can be reliably suppressed.

[0032] However, this example does not exclude a structure in which a part of the adhesive 8 is not arranged on the end surface of the insulating portion 2 on the one side D3a in the third direction. In addition, in at least a part of the periphery of the opening portion 7, regardless of whether at least a part of the adhesive 8 is arranged on the one side D3a in the third direction of the cable 3, the cable 3 is positioned relative to the substrate 4, and the displacement, distortion, etc. of the cable 3 are suppressed. In the case where at least a part of the periphery of the opening portion 7 is not arranged on the other side D3b in the third direction of the cable 3, when the cable 3 is displaced or distorted, the periphery of the opening portion 7 of the cable 3 abuts against the adhesive 8 arranged in the opening portion 7, thereby restricting its movement. In the case where at least a part of the periphery of the opening portion 7 is arranged on the other side D3b in the third direction of the cable 3, when the cable 3 is displaced or distorted, the periphery of the opening portion 7 of the cable 3 is also restricted by the adhesive 8 arranged in the opening portion 7.

[0033] In other words, the opening 7 provided on the cable 3 functions as a depression. On the other hand, the adhesive 8 disposed in the opening 7 functions as a projection. That is, the projection disposed in the depression restricts the movement of the depression. In this way, although it is not easy to provide a projection on the substrate 4 that engages with the depression provided on the cable 3 and restricts the movement of the cable 3, by disposing the adhesive 8 on the end surface on the side D3a of the third direction of the substrate 4 in a manner such that at least a portion of the adhesive 8 disposed by coating is disposed in the opening 7, the adhesive 8 is disposed on the end surface on the side D3a of the third direction of the substrate 4, and the adhesive 8 is cured in accordance with the shape of the opening 7, so that a projection that engages with the depression of the opening 7 (that is, a fitting structure of the projection relative to the depression) can be easily provided.

[0034] In addition, it is preferable to sandwich an adhesive 8 between the cable 3 and the substrate 4 in the third direction D3. Figure 2 As shown, an adhesive 8 is arranged between the end surface of the cable 3 (insulating portion 2) on the other side D3b in the third direction and the end surface of the substrate 4 on the one side D3a in the third direction at least in a portion of the outer edge of the end portion of the opening 7 on the other side D3b in the third direction. In this way, the engagement strength of the projection (adhesive 8 in the opening 7) with respect to the above-mentioned recess (opening 7) (i.e., the engagement strength of the projection with respect to the recess) can be improved.

[0035] exist Figure 1, the opening 7 is located at the outer end of the second direction D2 of the edge portion 6. That is, the opening 7 opens at the end of the second direction D2 of the edge portion 6. However, the present invention is not limited to this example, and the opening 7 may be separated from the outer end of the second direction D2 of the insulating portion 2 (the edge portion 6) toward the inner side of the second direction D2 when viewed from the third direction D3. In other words, at least one of the openings 7 may be arranged between the outer end of the second direction D2 of the insulating portion 2 (the edge portion 6) and the conductive wire 1 with a gap therebetween when viewed from the third direction D3.

[0036] The opening 7 is a hole-shaped hole formed by trimming the periphery of the insulating portion 2, and one opening 7 is disposed in each edge portion 6. The shape of the opening 7 is Figure 1 It is a rectangle when observed from the third direction D3. However, not limited to this example, the shape of the opening portion 7 observed from the third direction D3 may be a shape other than a rectangle, for example, it may be a triangle or other n-sided shape (n is a positive integer greater than 3), a circle, a semicircle, etc. In addition, at least one edge portion 6 may also have a plurality of opening portions 7. Moreover, in at least one edge portion 6, at least one of the plurality of opening portions 7 may also be located at the outer end of the second direction D2 of the edge portion 6. That is, all the opening portions 7 may be arranged at the outer end of the second direction D2 of the edge portion 6. Alternatively, a part of the plurality of opening portions 7 may be arranged at the outer end of the second direction D2 of the edge portion 6, and the other part may be arranged away from the outer end of the second direction D2 of the edge portion 6 toward the inner side of the second direction D2.

[0037] By positioning at least one of the openings 7 at the end of the edge 6 in the second direction D2, both ends of the cable 3 in the second direction D2 can be positioned relative to the substrate 4, thereby more reliably suppressing the deviation and twisting of the cable 3. Furthermore, the operation of disposing the adhesive 8 on the end surface of the substrate 4 on the one side D3a in the third direction around the cable 3 and the operation of disposing the adhesive 8 on the end surface of the substrate 4 on the one side D3a in the third direction in the opening 7 can be performed successively, thereby improving the operability of disposing the adhesive 8.

[0038] At this time, at least a portion of the adhesive 8 may be disposed on the third direction one side D3a side of the cable 3 at least a portion of the outer end in the second direction D2 of the insulating portion 2. In other words, a portion of the adhesive 8 disposed on the end surface on the third direction one side D3a side of the substrate 4 around the cable 3 is placed on the third direction one side D3a side of the cable 3 at least a portion of the outer end in the second direction D2 of the insulating portion 2. As a result, the cable 3 can be more reliably positioned relative to the substrate 4, and the displacement, twisting, etc. of the cable 3 can be more reliably suppressed.

[0039] Preferably, when viewed from the third direction D3, the width W1 of the opening 7 in the first direction D1 is greater than or equal to the width W0 of the conductive wire 1 in the second direction D2. For example, when viewed from the third direction D3, the maximum value of the width W1 of the opening 7 is greater than or equal to the minimum value of the width W0 of the conductive wire 1. In addition, preferably, when viewed from the third direction D3, the width W2 of the opening 7 in the second direction D2 is greater than or equal to the width W0 of the conductive wire 1 in the second direction D2. For example, when viewed from the third direction D3, the maximum value of the width W2 of the opening 7 is greater than or equal to the minimum value of the width W0 of the conductive wire 1. Here, the width W0 of the conductive wire 1 in the second direction D2 refers to the width defined by the position where the conductive wire 1 is led out from the insulating portion 2 to one side in the first direction D1, in other words, the width in the second direction D2 of the conductive wire end portion 5 on the other side of the first direction D1.

[0040] Since the opening 7 can be enlarged in this manner, the adhesive 8 disposed in the opening 7 can more reliably position the cable 3 relative to the substrate 4 , and can more reliably suppress displacement, twisting, etc. of the cable 3 .

[0041] In addition, it is preferable that the width W3 in the first direction D1 between the end of the wire end 5 on the other first direction D1b side and the end of the opening 7 on the first direction one direction D1a side is greater than the width W0 in the second direction D2 of the wire 1. For example, the minimum value of the width W3 is greater than the minimum value of the width W0 of the wire 1. In this way, it is possible to prevent the electronic component 9 arranged around the wire end 5 connected to the substrate 4 from deteriorating the workability of the arrangement of the adhesive 8.

[0042] In addition, it is preferred that the fixing mechanism of the insulating portion 2 to the substrate 4 may also use a member other than the adhesive 8. For example, the cable 3 further includes a fixing member 31. The fixing member 31 fixes the insulating portion 2 to the end surface on the side of the third direction D3a of the substrate 4. For example, the fixing member 31 is arranged between the insulating portion 2 and the substrate 4. Figure 1 In the embodiment, the fixing member 31 is arranged between the openings 7 respectively arranged at the edge 6 when viewed from the third direction D3, and particularly overlaps with the wire 1 when viewed from the third direction D3. In addition, the fixing member 31 is not particularly limited, and for example, a double-sided tape is used. However, the fixing member 31 is not limited to this example, and the fixing member 31 may also be an adhesive member that is the same as or different from the adhesive 8.

[0043] By configuring the fixing member 31, when a force at least in the third direction D3a side acts on the cable 3, the insulating portion 2 is not easily separated from the substrate 4 due to the fixing member 31. Therefore, the conductor 1 (particularly the conductor end 5) is not easily bent, so the fixing life of the cable 3 relative to the substrate 4 can be improved.

[0044] However, this example does not exclude a structure where the fixing member 31 is not disposed between the openings 7, nor does it exclude a structure where 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 structure where the cable 3 does not have the fixing member 31, wherein the cable 3 is disposed at the corresponding edge portion 6.

[0045] <1-1. First to third modified examples of the embodiment> Next, refer to Figures 3A to 5 , describing first to third variations of the implementation method. Figure 3A is a schematic diagram showing a structural example of an electronic device 100 according to a first modification example, in which a wire 1 drawn out from a cable 3 is connected to a substrate 4 . Figure 3B is a schematic diagram showing another structural example of the electronic device 100 according to the first modification, in which the wire 1 drawn out from the cable 3 is connected to the substrate 4 . Figure 4 is a schematic diagram showing a structural example of an electronic device 100 according to a second modification example, in which a wire 1 drawn out from a cable 3 is connected to a substrate 4 . Figure 5 1 is a schematic diagram showing a structural example of an electronic device 100 of a third variant, in which a wire 1 drawn from a cable 3 is connected to a substrate 4. In addition, in each variant, a structure different from the embodiment and other variants is described. In addition, in each variant, the same symbols are marked for the same components as the embodiment and other variants, and their description is sometimes omitted. In addition, the embodiment and its first to third variants can be implemented in any combination as long as no particular contradiction occurs.

[0046] <1-1-1. First Modification> In the above-mentioned embodiment, the opening 7 is provided as a through hole penetrating the edge portion 6 in the third direction D3. Figure 3A and Figure 3B In the first modified example shown, a cutout 10 is provided in a portion of the edge portion 6, and a portion of the edge portion 6 is bent at a fold 11 and arranged in a direction away from the substrate 4. In addition, in the above-mentioned embodiment, at least a portion of the adhesive 8 is arranged inside the opening 7, but in Figure 3A and Figure 3B In the first modification shown, at least a portion of the adhesive 8 is disposed between the portion of the edge portion 6 disposed in the direction away from the substrate 4 and the substrate 4 by means of the cutout 10 and the fold 11. In other words, the opening 7 may be formed by a through hole as in the embodiment, or may be formed by the cutout 10 and the fold 11 as in the first modification. In this case, the portion of the edge portion 6 disposed in the direction away from the substrate 4 covers at least a portion of the adhesive 8 disposed between the edge portion 6 and the substrate 4, and thus, it is possible to suppress the adhesive 8 from peeling off from the substrate 4.

[0047] Here, if Figure 3A As shown, two cutouts 10 extending along the second direction D2 may be provided, and the portion between the cutouts 10 may be bent toward the second direction D2. Figure 3B As shown, a cutout 10 extending along a first direction D1 and a cutout 10 extending along a second direction D2 are provided, and the edge portion of the cutout 10 is bent toward the first direction D1. Figure 3A and Figure 3B .

[0048] <1-1-2. Second Modification> In the second variant, if Figure 4 As shown in FIG. 1 , the cable 3 further includes a bottom plate 21. The bottom plate 21 protrudes from the end of the insulating portion 2 on the first direction D1a side toward the first direction D1a at one end of the cable 3 and extends along the second direction D2. The width of the bottom plate 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 21 has a higher flexibility than the insulating portion 2. In addition, the width of the bottom plate 21 in the second direction D2 is Figure 4 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. However, this example is not limited thereto, and the width of the bottom plate portion 21 in the second direction D2 is Figure 4 The width of the insulating portion 2 in the second direction D2 may be smaller than or larger than the width of the insulating portion 2 in the second direction D2.

[0049] Thus, when at least a force in the third direction D3a acts on the cable 3, the number of portions where the wire end portion 5 is easily bent can be increased compared to a configuration in which the cable 3 does not include the bottom plate portion 21.

[0050] For example, in a structure in which the cable 3 does not have the bottom plate portion 21, the wire end portion 5 is easily bent to a greater extent relative to the substrate 4 at a position in the first direction D1 that is the same as the end portion on the first direction one side D1a of the insulating portion 2. On the other hand, in the above-mentioned structure, the wire end portion 5 is easily bent relative to the substrate 4 at at least two locations including a position in the first direction D1 that is the same as the end portion on the first direction one side D1a of the bottom plate portion 21 and a position in the first direction D1 that is the same as the end portion on the first direction one side D1a of the insulating portion 2. Therefore, the degree of bending of each easily bendable location can be reduced. Therefore, the possibility of strength deterioration or breakage caused by bending on the wire 1 (especially the wire end portion 5) can be suppressed, and thus the fixing life of the cable 3 relative to the substrate 4 can be improved.

[0051] exist Figure 4 In the embodiment, at least a portion of the end surface of the bottom plate portion 21 on the other side D3b of the third direction is in contact with the end surface of the substrate 4 on the one side D3a of the third direction. Figure 4In the embodiment, the bottom plate portion 21 protrudes from the end portion of the insulating portion 2 on the side of the other third direction D3b. In this way, the portion of the end surface of the bottom plate portion 21 on the side of the other third direction D3b on the side of the other first direction D1b can be easily brought into contact with the end surface of the substrate 4 on the side of the one third direction D3a. 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 in a wider range in the first direction D1. Therefore, even if the above-mentioned force acts on the cable 3, the degree of bending of the bottom plate portion 21 can be further reduced.

[0052] However, the present invention is not limited to the above-mentioned examples, and at least a portion of the end surface of the bottom plate portion 21 on the other side D3b of the third direction may not be in contact with the end surface of the substrate 4 on the one side D3a of the third direction, and for example, may be bonded to the end surface of the substrate 4 by an adhesive component or the like. In addition, the above-mentioned examples do not exclude a structure in which the bottom plate portion 21 does not protrude from a portion of the insulating portion 2 on the other side D3b of the third direction at the end portion on the one side D1a of the first direction of the insulating portion 2. For example, at the end portion on the one side D1a of the first direction of the insulating portion 2, the bottom plate portion 21 may protrude from a portion on the one side D3a of the third direction of the insulating portion 2, or may protrude from a portion between the two ends of the insulating portion 2 on the third direction D3. In these cases, it is also the same as Figure 4 Likewise, the fixing life of the cable 3 with respect to the substrate 4 can be improved.

[0053] In addition, Figure 4 In the figure, the bottom plate portion 21 is arranged between the conductor 1 (especially the conductor end 5) and the substrate 4 in the third direction D3. That is, the bottom plate portion 21 is arranged between the portion of the conductor end 5 on the other side D1b of the first direction and the substrate 4 (the end surface on the side D3a of the third direction). However, this example is not limited to the bottom plate portion 21, and the bottom plate portion 21 may not be arranged between the conductor 1 and the substrate 4 in the third direction D3. For example, the bottom plate portion 21 may be arranged at a position closer to the side D3a of the third direction than at least one conductor 1 (especially the conductor end 5). In this case, Figure 4 Likewise, the fixing life of the cable 3 to the substrate 4 can be improved.

[0054] <1-1-3. Third Modification> In the third variation, if Figure 5 As shown, the cable 3 further includes a protruding plate portion 22. The protruding plate portion 22 protrudes from the end of the insulating portion 2 in the first direction D1 toward the first direction D1a side at one end of the cable 3. Figure 5 In the embodiment, the protruding plate portion 22 is a pair, and when viewed from the third direction D3, they protrude from both ends of the insulating portion 2 in the second direction D2. However, the present invention is not limited to this example, and the protruding plate portion 22 may protrude from only one of the end on the second direction one side D2a and the end on the second direction other side D2b of the insulating portion 2.

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

[0056] In this way, the number of places where the wire end 5 of the cable 3 is easily bent can be further increased. For example, with respect to the substrate 4, the wire end 5 is easily bent at at least three places 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. Therefore, the degree of bending of each easily bent place can be further reduced. Therefore, the fixing life of the cable 3 with respect to the substrate 4 can be further improved.

[0057] For example, the protruding plate portion 22 protrudes from the end portion of the insulating portion 2 on the side of the other third direction D3b. In this way, the portion of the end surface of the protruding plate portion 22 on the side of the other third direction D3b on the side of the other first direction D1b can be easily brought into contact with the end surface of the substrate 4 on the side of the one third direction D3a. Therefore, the contact area between the protruding plate portion 22 and the substrate 4 can be increased, and the protruding plate portion 22 can be bent in a wider range in the first direction D1. Therefore, even if the above-mentioned force acts on the cable 3, the degree of bending of the protruding plate portion 22 can be further reduced.

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

[0059] In addition, as mentioned above, Figure 5In the embodiment, the cable 3 has a bottom plate portion 21. The at least one protrusion 22 may be integral with the bottom plate portion 21, or may be connected to the bottom plate portion 21 in the second direction D2. Alternatively, the at least one protrusion 22 may not be integral with the bottom plate portion 21, or may not be connected to the bottom plate portion 21 in the second direction D2.

[0060] However, this example does not exclude a structure 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 modification, the wire end portion 5 can be easily bent at at least two locations due to the protruding plate portion 22 as in the second modification. Therefore, the effect of improving the fixing life of the cable 3 to the substrate 4 can be obtained.
