Description

  The present invention relates to an attachment structure for attaching a coil device to a base using a fixing member.

  Since the coil device includes an iron core, the core member is heavy, and a dimensional error is caused by manufacturing. Therefore, it is necessary to attach the coil device to the base. Conventionally, as a technique for attaching the coil device to a base, for example, an example in which the coil device is pressed with a metal fitting and then screwed is disclosed (see, for example, Patent Document 1). In addition, an example in which a coil device is attached by screwing a metal fitting formed in a “U” shape so as to cover the upper surface and both side surfaces on the short side of the coil device is disclosed (see, for example, Patent Documents 2 and 3). ). Furthermore, the example which attaches a coil apparatus by screwing the metal fitting formed in the "U" shape so that the three side surfaces of a coil apparatus may be covered is disclosed (for example, refer patent document 4).

However, in the technique of Patent Document 1, when a tightening torque (which means rotational torque, hereinafter simply referred to as “torque”) is generated when the metal fitting is screwed to the seat, the metal fitting also rotates with the torque. End up. Since so-called co-rotation occurs, it is necessary to take measures such as fixing and tightening the metal fittings, and it takes time to assemble the coil device.
Further, in the techniques of Patent Documents 2 to 4, since the metal fitting formed in a “U” shape covers the three side surfaces of the coil device, rotation of the metal fitting can be prevented. However, if a dimensional error occurs in the core member that constitutes the coil device, the attachment itself cannot be performed when it is larger than the metal fitting size, and on the contrary, if it is smaller than the metal fitting size, it is attached in a wobbled state, thereby improving stability. It was missing.

  The present invention has been made in view of the above points, and prevents the rotation of a fixing member (such as a metal fitting) even when torque is generated when fastening with a rotary fastening means (such as a screw), and the core member. It is an object of the present invention to provide a mounting structure for a coil device that can absorb a height dimension even if a dimensional error occurs.

(1) Means for solving the problem (hereinafter, simply referred to as “solution means”) 1 rotates a fixing member and a coil device having a core member and a coil so as to be pressed from the upper surface of the coil device. A coil device mounting structure for mounting the coil device to the base using a type fastening means,
It is provided adjacent to a coil device to be attached, and has a plurality of seats on the base that are substantially the same height as the coil device, and one or more of the plurality of seats is provided on a side surface of the seat. A first surface portion formed in a planar shape so as to include at least a portion that resists torque generated by fastening of the rotary fastening means; and the fixing member is elastically deformed by bridging the plurality of seats The gist of the present invention is that the structure has a fastening attachment portion that is formed so as to be capable of being fastened by the rotary fastening means and a rotation stop portion that is in surface contact with the first surface portion and stops rotation.

  According to the solution 1, since the plurality of seats are formed from the base to substantially the same height as the coil device, when the fixing member is bridged to the plurality of seats, the fixing member can be elastically deformed at portions other than both ends. Since the fixing member is elastically deformed in this way, the height dimension can be absorbed even if a dimensional error occurs in the core member. In addition, the first surface portion includes at least a portion that resists torque generated by the fastening of the rotary fastening means, and the surface is in contact with the stop portion formed on the fixing member so as to prevent rotation. When doing so, the rotation of the fixing member can be prevented. Therefore, the conventional measures such as fixing and tightening the metal fitting are not necessary, and the assembly work time can be shortened.

(2) The solving means 2 is a coil device that attaches the coil device to a base using a fixing member and a rotary fastening means so as to press the coil device having a core member and a coil from the upper surface of the coil device. The mounting structure of
It is provided adjacent to a coil device to be attached, and has a plurality of seats on the base that are substantially the same height as the coil device, and one or more of the plurality of seats is provided on a side surface of the seat. It has a first surface portion and a first surface portion that are partly formed to include at least a portion that resists torque generated by fastening of the rotary fastening means, and the fixing member bridges the plurality of seats. The gist of the present invention is that it has a structure that is formed so as to be elastically deformable and that has a guide portion that guides the rotary fastening means and a rotation stop portion that comes into surface contact with the first surface portion and stops rotation.

  The solving means 2 is provided with a guiding portion (for example, a U-shaped notch) for guiding the rotating fastening means in place of the fastening mounting portion (for example, a hole) for fastening with the rotating fastening means. Different from the solution 1 described above. By providing such a guide portion, the fixing member can be bridged to the seat even after a part of the rotary fastening means is fastened first. Therefore, in addition to the operational effects of the above-described solution 1, the degree of freedom in the assembly procedure is increased.

(3) The solving means 3 is the coil device mounting structure described in the solving means 1 or 2, wherein at least one of the plurality of seats is formed separately from the first surface portion. The gist of the invention is that it has a second surface portion in which a part of the side surface of the seat is formed into a planar shape, and the fixing member has a reference portion that is positioned in surface contact with the second surface portion.

  According to the solution 3, the second surface portion is separate from the first surface portion, and a part of the side surface of the seat is formed in a planar shape, so that the second surface portion and the reference portion are brought into surface contact. Thereby, positioning with respect to the long side direction of a fixing member can be performed easily.

(4) The solving means 4 is the coil device mounting structure according to any one of the solving means 1 to 3, wherein one or more of the plurality of seats are provided with positioning reference holes, The gist of the invention is that the fixing member has a structure including a convex portion that enters the reference hole.

  According to the solution means 4, the fixing member can be easily positioned simply by inserting the convex portion into the reference hole. Therefore, the assembly work time can be further shortened.

(5) The solving means 5 is the mounting structure of the coil device according to any one of the solving means 1 to 4, wherein the fixing member has a corner portion at least at a part of the hole, and the corner A projecting portion that is projected along the periphery of the hole including the portion, and a fastening hole in which the projecting portion is fitted and the rotary fastening means can be fastened is formed on the seat. To do.

  According to the solution 5, when the protrusion is fitted into the binding hole, the protrusion cannot rotate in the fastening hole. When the fixing member is fastened to the plurality of seats by the rotary fastening means, the fixing member is prevented from rotating after the protrusion is fitted into the fastening hole. Therefore, even if torque is generated when fastening by the rotary fastening means, the fixing member is prevented from rotating, so that the assembly work time can be shortened.

(6) The solution means 6 is the coil device mounting structure described in any one of the solution means 1 to 5, wherein the plurality of seats are formed integrally with the base. And

  According to the solution 6, since the plurality of seats are formed integrally with the base, the number of parts is reduced. Therefore, the work of attaching the plurality of seats to the base becomes unnecessary, so that the time for assembling the coil device can be further shortened.

(7) The solving means 7 is a mounting structure of the coil device according to any one of the solving means 1 to 6, wherein the first surface portion and the rotation stopping portion are formed in a plane. The gist.

  According to the solving means 7, since both the 1st surface part and a rotation stop part are formed in a plane, a 1st surface part and a rotation stop part can be made to contact on a surface reliably. Accordingly, the torque generated by the fastening of the rotary fastening means is received on a flat surface and the force is not concentrated on one point, so that the rotation of the fixing member can be reliably prevented.

  According to the present invention, since the fixing member is elastically deformed, the dimension in the height direction can be absorbed even if a dimensional error occurs in the core member. In addition, since a part of the fixing member and a part of the side surface of the seat are in surface contact with each other, rotation of the fixing member can be prevented even if torque is generated when the rotary fastening means is used. Therefore, it is possible to shorten the time for assembling the coil device.

  The best mode for carrying out the present invention will be described below with reference to the drawings. In addition, when it says up and down, right and left, and a direction, it follows description of drawing. Moreover, in Embodiment 1-4, a screw is applied as a rotary fastening means.

[Embodiment 1]
The first embodiment is an example in which the corresponding portions of the presser fitting and the seat are formed in a planar shape to prevent the presser fitting from rotating. The first embodiment will be described with reference to FIGS. FIG. 1 is a perspective view showing a state before one side of the presser fitting is fastened with screws. About the structural example of a seat, a top view is represented in FIG. 2, and a side view is represented in FIG. About the structural example of a holding metal fitting, FIG. 4 represents a top view and FIG. 5 represents the VV sectional view taken on the line of FIG. FIG. 6 (A) shows a perspective view and FIG. 6 (B) shows a side view of the state after one side of the presser fitting is fastened with a screw. With respect to the torque generated by the fastening of the screw, FIG. 7A is a sectional view showing a structural example that cannot be opposed, and FIG. 7B is a sectional view showing a structural example that can be opposed. FIG. 8 is a perspective view showing a state after fastening all parts of the presser fitting with screws.

  First, as shown in FIG. 1, two seats 18 and 26 are integrally formed on the base 28. As shown in FIG. 2, the seat 26 is formed in a substantially rectangular parallelepiped shape, and four corners of the side surface are rounded with a predetermined radius. Therefore, the seat 26 has flat portions 26a, 26b, and 26c in which a part of the side surface is formed into a planar shape. The flat portion 26a and the flat portion 26c are opposed to each other, and the flat portion 26b is adjacent to the flat portions 26a and 26c. Of these, the flat portions 26a and 26c correspond to the first surface portion, and the flat portion 26b corresponds to the second surface portion (see Embodiment 2 described later). Further, as shown in FIG. 3, when the seat 26 is viewed from the side, it is formed in a trapezoidal shape and has substantially the same height as the coil device 20 from the upper surface of the base 28. As shown in FIG. 3, the seat 26 is provided adjacent to the coil device 20 to be attached, and a screw hole 30 for fastening a screw is formed in the upper end portion. The seat 18 is disposed adjacent to the opposite side across the seat 26 and the coil device 20, and has the same shape as the seat 26. Therefore, the seat 18 has flat portions 18 a, 18 b, 18 c corresponding to the flat portions 26 a, 26 b, 26 c and a screw hole 16 corresponding to the screw hole 30.

  Returning to FIG. 1, the coil device 20 is placed between the seats 18 and 26, and is fixed using the presser fitting 10. The coil device 20 includes a core member, a coil, and connection terminals 22 and 24, and corresponds to, for example, an inductor element or a transformer. The presser fitting 10 corresponds to a fixing member, and is obtained by bending an elongated plate-like member so as to bridge the seats 18 and 26 (see FIG. 4).

  The presser fitting 10 shown in FIG. 4 has at least flat portions 10a and 10c and an elastic portion 10b regardless of the material. The flat portion 10c has a hole 34 for passing a screw (except for the head), and a rotation piece 32 that makes a surface contact with the surface portion of the seat 26 (either one of the flat portions 26a and 26c) and stops the rotation. . The flat portion 10 a has the same shape as the flat portion 10 c, and has a hole 12 corresponding to the hole 34 and a rotation piece 14 corresponding to the rotation piece 32. These holes 12 and 34 correspond to fastening attachment portions. Further, each of the rotation stop pieces 14 and 32 corresponds to a rotation stop portion, and is also called “ear”. As is clear from the description of FIG. 4, the turning piece 14 and the turning piece 32 are provided on a diagonal line in the presser fitting 10.

  Further, as shown in FIG. 5, the flat portion 10 c is formed flat at one end portion of the presser fitting 10, and the flat portion 10 a is formed flat at the other end portion of the presser fitting 10. The elastic portion 10b provided at the center portion of the presser fitting 10 performs a function of pressing the coil device 20 and an elastic function. Specifically, the convex portion on the lower surface side serves to press against the coil device 20, and an elastic function like a leaf spring is achieved by a shape in which the cross section is bent into a “W” shape. As described above, since the elastic portion 10b of the presser fitting 10 is elastically deformed, the height dimension can be absorbed even if a dimensional error occurs in the core member.

  Next, a procedure for fixing the coil device 20 using the above-described presser fitting 10 will be briefly described. Returning again to FIG. 1, the coil device 20 is first placed between the seats 18 and 26. Thereafter, the flat portion 10 c of the presser fitting 10 is positioned on the upper surface of the seat 26, and the screw 36 is passed through the hole 34 and fastened to the screw hole 30. At the time of this screw tightening, after the head of the screw 36 contacts the presser fitting 10, torque as indicated by an arrow D2 shown in FIGS. 6 (A) and 6 (B) is generated.

  However, as shown in FIG. 6 (B), the rotation stop piece 32 and the flat portion 26c are brought into surface contact with each other so that the rotation preventing function is achieved. The posture of the presser fitting 10 does not change before and after the screw 36 is fastened. Therefore, as shown in FIG. 6A, the flat portion 10 a of the presser fitting 10 can be easily passed through the hole 12 and fastened to the screw hole 30. Both screws 36 and 38 correspond to rotary fastening means. In this example, the screws 36 are tightened in the order of the screws 38. However, since the presser fitting 10 is symmetrical, the same holds true when the screws 38 are tightened in the order of the screws 38. Therefore, the conventional measures such as fixing and tightening the metal fitting are not necessary, and the assembly work time can be shortened. FIG. 8 shows a state after the coil device 20 is fixed by the presser fitting 10 in this way.

  Further, since the rotation stop piece 14 and the rotation stop piece 32 are provided on the diagonal line in the presser fitting 10, the above-described fixing can be performed even if the arrangement is reversed when bridged to the seats 18 and 26. In addition, as long as the rigidity of the rotation stop piece 32 resists the torque generated at the time of screw tightening, the deformation of the rotation stop piece 32 can be prevented. Therefore, it is desirable to form the rotation stop piece 32 with high rigidity.

Here, in order to counter the torque generated by the fastening of the screw, the conditions required for the rotating piece and the flat portion will be described with reference to FIG. In order to simplify the description, the seat 26 shown in FIG. 7 has a structure including only the flat portion 26c.
FIG. 7A shows an example in which the presser fitting 10 is formed so that the rotating piece 32 contacts only the right side portion from the center line of the seat 26 (indicated by a one-dot chain line in the drawing) in the flat portion 26c. . In this example, when a torque as indicated by an arrow D <b> 2 is generated by fastening the screw 36, this torque works clockwise around the screw 36. Therefore, the rotation piece 32 receives the force as indicated by the arrow D4 and rotates, and thus moves away from the flat portion 26c like a two-dot chain line.

  On the other hand, FIG. 7B shows an example in which the presser fitting 10 is formed so that the rotation piece 32 is in contact only with the left portion of the flat portion 26c from the center line of the seat 26. As in the example described above, when torque as indicated by the arrow D2 is generated, the rotation stop 32 receives a force as indicated by the arrow D6 (the same force as the arrow D4) and tries to rotate. However, since a force directed to the flat surface portion 26c acts on the rotation piece 32, the flat surface portion 26c resists torque and prevents the rotation. In this example, the presser fitting 10 is formed so that the rotation piece 32 is in contact with only the left side portion. Similar results are obtained.

  Therefore, the condition required to counter the torque generated by the fastening of the screw 36 is that at least the left side portion of the flat portion 26c from the center line of the seat 26 (the portion is “torque generated by fastening of the rotary fastening means”). The presser fitting 10 is formed so that the rotation-stopping piece 32 comes into contact so as to include “a portion that resists”. However, if the screw 36 is tightened counterclockwise and fastened, at least the right portion from the center line of the seat 26 corresponds to “a portion that resists torque generated by fastening of the rotary fastening means”. This condition is similarly applied to the relationship between the rotating piece 14 and the flat portion 18a (seat 18).

[Embodiment 2]
The second embodiment is an example for facilitating positioning in the long side direction of the presser fitting, and will be described with reference to FIGS. 9 to 12. FIG. 9 is a perspective view showing a state before one side of the presser fitting is fastened with a screw. About the structural example of a clamp, FIG. 10 represents a top view and FIG. 11 represents the XI-XI sectional view taken on the line of FIG. FIG. 12 shows a perspective view after one side of the presser fitting is fastened with a screw. For simplicity of illustration and description, the second embodiment will be described with respect to differences from the first embodiment. Therefore, the same elements as those used in Embodiment 1 are denoted by the same reference numerals, and description thereof is omitted.

  In FIG. 9, the presser fitting 40 corresponds to a fixing member, and is obtained by bending an elongated plate-like member so as to bridge the seats 18 and 26 as in the first embodiment. A configuration example of the presser fitting 40 is shown in FIGS. Compared to the presser fitting 10 of the first embodiment (see FIGS. 4 and 5), the presser fitting 40 is different in that a reference piece 42 is provided on the flat portion 10 c in addition to the rotation stop piece 32. The reference piece 42 corresponds to a reference portion, and is formed so as to be able to come into surface contact with the flat portion 26b shown in FIG. In addition, although the rotation piece 32 and the reference | standard piece 42 were integrally formed as the L-shaped part 44 in the example mentioned above, you may form separately.

  Next, a procedure for fixing the coil device 20 using the above-described presser fitting 40 will be briefly described. Returning to FIG. 9, the coil device 20 is first placed between the seats 18 and 26. Thereafter, the reference piece 42 of the flat portion 10 c is brought into contact with the flat portion 26 b of the seat 26, thereby positioning the presser fitting 40 in the long side direction. Subsequently, the flat portion 10 c is positioned on the upper surface of the seat 26, and the screw 36 is passed through the hole 34 and screwed into the screw hole 30. When the screw is tightened, torque is generated in the same manner as in the first embodiment, and the presser fitting 40 is rotated. However, since the rotation stop piece 32 functions to prevent rotation, the posture of the presser fitting 40 does not change before and after the screw 36 is fastened. Accordingly, as shown in FIG. 12, the flat portion 10 a of the presser fitting 10 can be easily passed through the hole 12 and fastened to the screw hole 30. In addition, since the state after fixing the coil apparatus 20 with the presser fitting 40 is the same as that of Embodiment 1 mentioned above (refer FIG. 8), illustration and description are abbreviate | omitted.

  In this way, the plane portion 26b and the reference piece 42 are brought into surface contact with each other, whereby the presser fitting 40 can be easily positioned in the long side direction. Further, since the flat portion 10c has the stop piece 32, the effects such as the point that the screw 38 can be easily passed through the hole 12 and fastened to the screw hole 30 and the assembly work time can be shortened are described above. This is the same as the first embodiment. Furthermore, since the rotation stop piece 14 and the rotation stop piece 32 are provided on the diagonal line of the presser fitting 40, the above-described fixing can be performed even if the arrangement is reversed when bridged to the seats 18 and 26.

[Embodiment 3]
The third embodiment is an example for facilitating the positioning of the presser fitting, and will be described with reference to FIGS. FIG. 13 is a perspective view showing a state before one side of the presser fitting is fastened with screws. FIG. 14 is a plan view showing a configuration example of the seat. About the structural example of a holding metal fitting, FIG. 15 represents a top view and FIG. 16 represents the XVI-XVI sectional view taken on the line of FIG. FIG. 17 shows a perspective view after one side of the presser fitting is fastened with a screw. For simplicity of illustration and description, the third embodiment will be described with respect to differences from the first embodiment. Therefore, the same elements as those used in Embodiment 1 are denoted by the same reference numerals, and description thereof is omitted.

  In FIG. 13, the presser fitting 54 corresponds to a fixing member, and is obtained by bending a long and slender plate-like member so as to bridge the seats 18 and 50 as in the first embodiment. The seat 50 is an alternative to the seat 26 (see FIG. 2) in the first embodiment, and its configuration example is shown in FIG. Compared with the seat 26 of FIG. 2, the seat 50 has a reference hole 52 in addition to the screw hole 30. The reference hole 52 corresponds to a “positioning reference hole”, and is large enough to contain a small piece 56 described later. The seat 50 has flat portions 50a, 50b, and 50c, and is formed in the same side shape as the seat 26 shown in FIG. The flat portions 50a, 50b, and 50c are formed in the same manner as the flat portions 26a, 26b, and 26c in the first embodiment, respectively.

  Moreover, the structural example of the holding metal fitting 54 is represented to FIG. 15, FIG. Compared to the presser fitting 10 of the first embodiment (see FIGS. 4 and 5), the presser fitting 54 is different in that a small piece 56 is provided on the flat portion 10c in addition to the rotating piece 32. The small piece 56 corresponds to a convex portion, and is formed on the long side opposite to the rotation stopping piece 32.

  Next, a procedure for fixing the coil device 20 using the above-described presser fitting 54 will be briefly described. Returning to FIG. 13, the coil device 20 is first placed between the seats 18 and 50. Thereafter, the small piece 56 of the presser fitting 54 is inserted into the reference hole 52 of the seat 50 to position the presser fitting 54. By this positioning, the flat portion 10 c can be positioned on the upper surface of the seat 50, and then the screw 36 is passed through the hole 34 and screwed into the screw hole 30. When the screw is tightened, torque is generated in the same manner as in the first embodiment, and the presser fitting 54 is to be rotated. However, since the rotation piece 32 and the flat surface portion 50c come into surface contact to prevent rotation, the posture of the presser fitting 54 does not change before and after the screw 36 is fastened. Therefore, as shown in FIG. 17, the flat portion 10 a of the presser fitting 10 can be easily passed through the hole 12 and fastened to the screw hole 30. In addition, since the state after fixing the coil apparatus 20 with the presser fitting 54 is the same as that of Embodiment 1 mentioned above (refer FIG. 8), illustration and description are abbreviate | omitted.

  Therefore, the presser fitting 54 can be easily positioned simply by inserting the small piece 56 into the reference hole 52. Further, since the flat portion 10c has the stop piece 32, the effects such as the point that the screw 38 can be easily passed through the hole 12 and fastened to the screw hole 30 and the assembly work time can be shortened are described above. This is the same as the first embodiment. Furthermore, since the rotation stop piece 14 and the rotation stop piece 32 are provided on the diagonal line in the presser fitting 54, the above-described fixing can be performed even if the arrangement is reversed when bridged to the seats 18 and 50.

[Embodiment 4]
The fourth embodiment is an example in which the presser fitting having a structure different from that of the first embodiment is used to prevent the presser fitting from rotating. The fourth embodiment will be described with reference to FIGS. FIG. 18 is a perspective view showing a state before one side of the presser fitting is fastened with a screw. About the structural example of a seat, a top view is represented in FIG. 19, and a side view is represented in FIG. FIG. 21 shows a plan view of a configuration example of the presser fitting, and FIG. 22 shows a cross-sectional view taken along line XXII-XXII of FIG. FIG. 23 is a perspective view showing a state after one side of the presser fitting is fastened with a screw. For simplicity of illustration and description, the third embodiment will be described with respect to differences from the first embodiment. Therefore, the same elements as those used in Embodiment 1 are denoted by the same reference numerals, and description thereof is omitted.

  In FIG. 18, the presser fitting 60 corresponds to a fixing member, and is obtained by bending an elongated plate-like member so as to bridge the seats 18 and 26 as in the first embodiment. The seats 18 and 26 replace the seats 18 and 26 (see FIG. 2) in the first embodiment, and their configuration examples are shown in FIGS. 19 and 20. Compared with the screw hole 30 shown in the seat 26 of FIG. 2, the seat 26 shown in FIGS. 19 and 20 has a stepped screw hole 68. The screw hole 68 corresponds to a fastening hole. A portion 68a having a large diameter in the screw hole 68 is a hole having a size into which the cylindrical portion 66 provided in the presser fitting 60 is inserted, as represented by a two-dot chain line in FIG. Further, a portion 68 b having a small diameter in the screw hole 68 is a hole for fastening a screw similarly to the screw hole 30. On the other hand, the seat 18 is disposed on the opposite side of the seat 26 and the coil device 20, but has the same shape as the seat 26. Therefore, the seat 18 has a screw hole 64 corresponding to the screw hole 68 (see FIG. 18).

  Moreover, the structural example of the holding metal fitting 60 is represented to FIG. 21, FIG. Compared to the presser fitting 10 of the first embodiment (see FIGS. 4 and 5), the presser fitting 60 includes a cylindrical portion 62 in the flat portion 10 a instead of the rotation stop piece 14, and a cylinder instead of the rotation stop piece 32. The difference is that the portion 66 is provided in the flat portion 10c. These cylindrical portions 62 and 66 correspond to protrusions, and can be formed by burring, for example.

  Next, a procedure for fixing the coil device 20 using the presser fitting 60 described above will be briefly described. Returning to FIG. 18, the coil device 20 is first placed between the seats 18 and 26. The presser fitting 60 is bridged between the seat 18 and the seat 26 so that the cylindrical portion 62 enters the screw hole 64 and the cylindrical portion 66 enters the screw hole 68. Subsequently, the screw 36 is passed through the hole 34 and screwed into the screw hole 68. During the screw tightening, torque is generated (in the direction of arrow D2 shown in FIG. 23) in the same manner as in the first embodiment described above, and the presser fitting 60 tries to rotate. However, as described above, since the cylindrical portion 62 enters the screw hole 64 and the cylindrical portion 66 enters the screw hole 68, the anti-rotation function is achieved. Thus, the posture of the presser fitting 60 does not change before and after the screw 36 is fastened. Therefore, as shown in FIG. 23, the flat portion 10 a of the presser fitting 60 can be easily passed through the hole 12 and fastened to the screw hole 30. In addition, since the state after fixing the coil apparatus 20 with the presser fitting 60 is the same as that of Embodiment 1 mentioned above (refer FIG. 8), illustration and description are abbreviate | omitted.

  Therefore, when the presser fitting 60 is bridged to the seats 18 and 26, the cylindrical portion 62 is inserted into the screw hole 64 and the cylindrical portion 66 is inserted into the screw hole 68, thereby preventing the presser fitting 60 from rotating and easily. The presser fitting 60 can be positioned. In this example, the screws 36 are tightened in the order of the screws 38. However, since the presser fitting 60 is symmetric, the above-described fixing can be similarly performed when the screws 38 are tightened in the order of the screws 36.

  In the above-described example, the flat portion 10a of the presser fitting 60 includes the cylindrical portion 62, and the flat portion 10c includes the cylindrical portion 66. However, one or both of the cylindrical portions 62 and 66 are replaced with the cylindrical portion. A square tube portion may be provided. In the example shown in FIGS. 24 and 25, the flat portion 10a of the presser fitting 70 corresponding to the fixing member is provided with a square tube portion 72, and the flat portion 10c is provided with a square tube portion 74. Each of the square tube portions 72 and 74 corresponds to a “projection portion”, and each corner portion corresponds to a “corner portion for preventing rotation”. Moreover, it is necessary to form the site | part 68a of the screw hole 68 in the shape in which the square cylinder part 74 fits (refer FIG. 20). The same applies to the screw hole 64 corresponding to the rectangular tube portion 72.

When the flat portions 10a and 10c are formed in a square tube shape as described above, the square tube portions 72 and 74 cannot be rotated in the screw holes 64 and 68 even if torque is generated during screw tightening. Therefore, since the rotation of the presser fitting 70 can be reliably prevented, the assembly work time can be shortened.
In this example, the square tube portions 72 and 74 are formed in a square tube, but may be formed in another polygonal tube such as a triangular tube or a hexagonal tube. In addition, even when a structure in which either one of the square tube portions 72 and 74 is not formed on the presser fitting 70 is obtained, the same effect can be obtained. Further, if at least one corner is provided, the anti-rotation function is achieved, so that the other part may be circular.

[Other Embodiments]
Although the best mode for carrying out the present invention has been described in Embodiments 1 to 4 above, the present invention is not limited to these modes. In other words, the present invention can be implemented in various forms without departing from the gist of the present invention. For example, the following forms may be realized.

(1) In the first, second, and third embodiments, the two end portions of the presser fitting (the presser fittings 10, 40, and 54), that is, the flat portion 10a and the flat portion 10c are provided with two stop portions (the stop pieces 14 and 32). ) On the diagonal (see FIGS. 1, 9, and 13). Instead of this form, it is good also as a structure provided with two rotation stop parts on the same long side. For example, the holding metal fitting 80 shown in FIGS. 26 and 27 has a structure including a rotation piece 82 (in place of the rotation piece 14) on the same long side as the side provided with the rotation piece 32. An example in which the coil device 20 is fixed using the presser fitting 80 is shown in FIG.

  In FIG. 28, since it is normal to screw the screw clockwise, it is necessary to screw the screw 38 on the left side of the drawing after screwing the screw 36 on the right side of the drawing. Even if a torque is generated when the screw 38 is screwed first, not only the rotation preventing function of the rotation stopping piece 32 but also the rotation stopping piece 82 in surface contact with the surface portion of the seat 18 also functions as a rotation stopping function. Therefore, although the order of screw tightening is restricted, the rotation of the presser fitting 80 due to the generated torque can be more reliably prevented.

(2) In the first to fourth embodiments, the holes 12 through which screws (excluding the head) are passed through both ends of the holding fitting (holding fittings 10, 40, 54, 60, 70), that is, the flat portions 10a, 10c. , 34 (see FIGS. 1, 9, 13, and 18). Instead of this form, a structure may be adopted in which guide portions for guiding screws are provided at positions corresponding to the holes 12 and 34, respectively. For example, the presser fitting 90 shown in FIGS. 29 and 30 has a guide portion 92 for guiding a screw at a position corresponding to the hole 12 in the flat portion 10a, and guides a screw to a position corresponding to the hole 34 in the flat portion 10c. A structure having a guide portion 94 was adopted. An example in which the coil device 20 is fixed using the presser fitting 90 is shown in FIGS.

  First, as shown in FIG. 31, the screw 36 is partially screwed before the presser fitting 90 is bridged to the seats 18 and 26. Subsequently, the guide member 94 is passed through the gap between the head of the screw 36 and the upper surface of the seat 26, and the presser fitting 90 is bridged to the seats 18 and 26. FIG. 32 shows a state where the presser fitting 90 is bridged in this way. After the screw 36 is tightened, the screw 38 is tightened. Torque is generated when the screw 36 is tightened, but the rotation stop piece 32 is in surface contact with the surface portion of the seat 26 in the same manner as in the first embodiment to perform a rotation preventing function. In addition, since the presser fitting 90 is symmetrical, the same holds true when the screws 38 are tightened in the order of the screws 36. Therefore, rotation of the presser fitting 90 accompanying the torque generated as described above can be prevented. In this example, only the screw 36 is screwed first, but the same result can be obtained by screwing both the screws 36 and 38 first.

(3) In the first to fourth embodiments, the elastic portion 10b of the holding fitting (holding fitting 10, 40, 54, 60, 70) is formed by bending the cross section into a “W” shape, and the apex on the lower surface side (or The structure is such that the convex plane is pressed against the coil device 20 (see FIGS. 5, 11, 16, 22, and 25). Instead of this structure, the cross section may be bent to another shape. The other shape corresponds to a non-flat shape such as “S” shape (or wave shape), “U” shape, or the like. Even in these cross-sectional shapes, the elastic portion 10b performs an elastic function like a leaf spring, so that the height dimension can be absorbed even if a dimensional error occurs in the core member.

(4) In the first to fourth embodiments, the two seats 18 and 26 are integrally formed on the base 28 (see FIGS. 1, 3 and 20). Instead of this structure, three or more seats may be formed integrally with the base 28. In this case, the presser fitting may be formed in a shape that bridges all three or more seats formed on the base 28. For example, when four seats are formed, the presser fitting is formed in a cross shape. In the case of bridging to the second seat, the presser fittings 10, 40, 54, 60, 70, 80, 90 can be used as they are. Moreover, it is good also as a structure attached to the base 28, after forming at least 1 seat separately. Regardless of the structure, since the coil device 20 can be fixed using the presser fitting, the same effect as the first to fourth embodiments can be obtained.

(5) In the first to fourth embodiments, a plurality of seats (seats 18, 26, 50) are formed at substantially the same height as the coil device 20 from the upper surface of the base 28 (FIGS. 1, 3, 3 and 20). See). Instead of this structure, a plurality of seats may be formed higher (or lower) than the coil device 20. For example, when it is formed higher than the coil device 20, it is necessary to be formed by bending the flat portions 10a, 10c of the presser fitting into an inverted “L” shape. In addition, when formed lower than the coil device 20, it is necessary to bend the flat portions 10 a and 10 c of the presser fitting into an “L” shape. That is, the flat portions 10a and 10c are formed by bending so as to fill in the difference between the height of the plurality of seats and the height of the coil device 20. By carrying out like this, the coil apparatus 20 can be fixed similarly to Embodiment 1-4 mentioned above.

(6) In the first to third embodiments, a plurality of seats (seats 18, 26, 50) are provided with surface portions (plane portions 18a, 18b, 18c, plane portions 26a, 26b, 26c, planes) on a part of all the seats. Portions 50a, 50b, 50c) were formed (see FIGS. 2, 3, 9, 12, etc.). Instead of this form, one or more seats (excluding all seats) among the plurality of seats may be arbitrarily selected to form the surface portion. Taking FIG. 1 of Embodiment 1 as an example, a structure in which one side seat 26 is provided with flat portions 26a, 26b, and 26c and the other side seat 18 is not provided with a surface portion is applicable. In this case, even if the retaining piece 14 is provided on the presser fitting 10, it does not function as a detent, and is unnecessary. Further, since the screw 36 on the right side of the drawing needs to be screwed in correspondence with the seat 26 having the flat portions 26a, 26b, and 26c, the screw 38 on the left side of the drawing needs to be screwed, so that the fastening order is restricted. Except for this point, the rotation stop piece performs the rotation prevention function as in the first to third embodiments, so that the rotation of the presser fitting can be prevented and the assembly work time can be shortened.

  Note that the shape of the surface portion formed on the presser fitting or the seat may be arbitrary. That is, taking FIG. 1 of Embodiment 1 as an example, it is not necessary to form one or both of the planar portion 26c and the locking piece 32 in a plane, and for example, a curved surface or an uneven surface may be used. For example, when the flat surface portion 26c is a curved surface, the cross-sectional shape of the seat can be an ellipse. Furthermore, for example, it is also possible to form the flat portion 26c with a concave surface and form the locking piece 32 with a convex surface. In any case, it is desirable that the flat portion 26c and the rotation piece 32 be formed so as to be in contact with each other. Even the flat portion 26c and the rotation piece 32 formed as described above can resist the torque generated by the fastening of the screws 36 and 38, so that the rotation of the presser fitting can be prevented.

(7) In the first to fourth embodiments, the screws 36 and 38 are applied as the rotary fastening means (see FIG. 8, FIG. 12, FIG. 17, FIG. 23, etc.). Instead of this form, the presser fitting may be fastened using a rotary fastening means other than a screw (for example, a bolt or the like). Even in this case, the rotation of the presser fitting can be prevented.
