Description

  The present invention relates to a conductive member.

  As a conductive member that can be surface-mounted on an electronic circuit board, a surface-mounted contact in which a conductive coil spring is attached to one end of a metal base has been proposed (for example, see Patent Document 1).

JP 2009-38005 A

  However, the surface mount contact described above is configured such that one end of the coil spring is attached to the metal base and the other end of the coil spring is in contact with a conductor such as a housing panel. Therefore, the conductive path length from one end of the coil spring to the other end is correspondingly increased. Therefore, since the impedance value tends to be high, a sufficient noise reduction effect may not be obtained under a situation where a lower impedance value is required.

  In view of the above circumstances, it is desirable to provide a conductive member that can improve conductivity more than the conventional product.

  The conductive member described below includes a conductive oblique coil and a conductive base portion. The oblique coil is formed in a spiral shape in which the radial direction of the spiral is inclined with respect to the axial direction of the spiral. The base portion has a solderable joint surface, and a tilt coil is attached to a location opposite to the joint surface. When using the conductive member, the joint surface of the base portion is soldered to the first member. A second member is disposed on the opposite side of the first member across the base portion and the inclined coil. The base portion and the inclined coil are sandwiched between the first member and the second member. At this time, the oblique coil contacts the second member on the outer periphery of the oblique coil while being elastically deformed. Thereby, the first member and the second member are electrically connected.

  According to the conductive member configured as described above, the outer periphery of the oblique coil contacts the second member. Therefore, each of the plurality of loops included in the oblique coil contacts the second member. Therefore, the oblique coil and the second member are in contact at multiple points. Moreover, the conductive path between the first member and the second member configured between the plurality of contact points matches the direction between the first member and the second member with the axial direction of the coil so that the coil is the first member. -The path length is shorter than the conductive path configured when sandwiched between the second members. Therefore, with such a conductive member, the conductivity is improved more than the conventional product, and the impedance value can be easily lowered. Therefore, an excellent noise reduction effect can be obtained by using such a conductive member to electrically connect, for example, a metal casing or a metal component that becomes a noise radiation source and a ground on the electronic circuit board. Can do.

  In the case of the conductive member, the plurality of loops included in the inclined coil are elastically deformed individually and contact the second member. Therefore, even when the flatness on the second member side is low or the parallelism between the second member side and the conductive member side is low, the conductive member can be brought into multipoint contact with the second member as designed. Therefore, if it is such a conductive member, unlike the conductive member provided with the metal piece that contacts the second member on the surface, the second member is caused by variation in the inclination of the metal piece with respect to the second member. And the metal piece is not in line contact or point contact. Therefore, if it is the said electroconductive member, dispersion | variation does not arise easily in the contact state with respect to a 2nd member, and an electrical connection state can be stabilized.

The conductive member as described above may further have the following configuration.
First, in the conductive member, the oblique coil has a shape in which the outer periphery forms an elliptical outline when viewed from the axial direction of the spiral, and the axial direction of the spiral and the major axis direction of the elliptical shape are on the joint surface. Alternatively, it may be mounted on the base portion so as to be substantially parallel to the base portion.

  According to the conductive member configured in this way, when a pressing force is applied from the second member to the oblique coil, each of the plurality of loops included in the oblique coil is easily inclined. Therefore, the repulsive force that acts on the second member from the oblique coil can be reduced.

  The conductive member may have a cut and raised portion. The cut-and-raised portion is formed by cutting and raising a part of the base portion. By abutting against a part of the inclined coil at the cut-and-raised portion, a predetermined displacement or more relative to the base portion of the inclined coil is restricted.

According to the conductive member configured as described above, it is possible to suppress the oblique coil from being displaced toward the cut and raised portion at the contact portion between the cut and raised portion and the inclined coil.
The conductive member may have a caulking portion. The caulking portion is formed by curving a portion extending from the base portion, arranging a part of the inclined coil inside the curving portion, and caulking the curving portion. By holding a part of the inclined coil inside the curved portion in the caulking portion, a predetermined displacement or more with respect to the base portion of the inclined coil is restricted.

According to the conductive member configured as described above, it is possible to suppress the displacement of the oblique coil at the location where the oblique coil is held by the caulking portion.
The conductive member may have a hole or a recess formed in the base portion. By fitting a part of the tilt coil into such a hole or recess, displacement of the tilt coil with respect to the base portion is restricted.

According to the conductive member configured as described above, it is possible to suppress the displacement of the oblique coil at the place where the oblique coil is fitted in the hole or the recess.
The conductive member may have a wall portion. The wall portion extends from the base portion and is disposed at a location where the extended portion can contact the outer periphery of the inclined coil on both sides of the inclined coil. By abutting against a part of the inclined coil with such a wall portion, a predetermined displacement or more with respect to the base portion of the inclined coil is regulated.

According to the conductive member configured in this way, since the oblique coil is sandwiched between the wall portions, the displacement of the oblique coil in a direction deviating from between the wall portions can be suppressed.
The conductive member may have a sandwiching portion. The sandwiching portion extends from the base portion, and the extending portion is disposed on the inner peripheral side of the tilt coil, and sandwiches the tilt coil with the base portion on the outer periphery side of the tilt coil. By sandwiching a part of the oblique coil between the sandwiching part and the base part, displacement of the oblique coil with respect to the base part is restricted.

According to the conductive member configured as described above, it is possible to suppress the oblique coil from being displaced toward the sandwiching portion or the base portion.
Moreover, when it has the above-mentioned clamping part, the said electrically-conductive member may be comprised so that the extension direction front-end | tip part of a clamping part may be soldered to a 1st member.

  According to the conductive member configured as described above, it is possible to suppress the distal end portion in the extending direction of the sandwiching portion from being displaced in a direction away from the first member side. Therefore, it is possible to suppress the oblique coil from being displaced toward the sandwiching portion with the deformation of the sandwiching portion.

  In the above conductive member, the oblique coil may be formed by a part of the wire. In this case, the gripped portion is further gripped by the gripped portion formed by forming the remaining part of the wire in a spiral shape having a diameter smaller than that of the inclined coil and the portion extending from the base portion. You may have the holding part comprised so that it was possible. By gripping the gripped portion with such a gripping portion, the displacement of the oblique coil with respect to the base portion is restricted by a predetermined amount or more.

  According to the conductive member configured as described above, the gripped portion having a diameter smaller than that of the tilt coil is gripped by the grip portion, so that the grip portion is larger than the grip portion having a size corresponding to the diameter of the tilt coil. Can be reduced in size, and the conductive member can be made compact.

In the case of the conductive member having the gripping part and the gripped part as described above, the gripped part may be formed at a position shifted from the position of the central axis of the inclined coil toward the base part by a predetermined distance. .
According to the conductive member configured in this way, since the gripped portion as described above is added to the oblique coil, directionality occurs in the oblique coil. Therefore, when the oblique coil is attached to the base portion, the oblique coil is surely in a predetermined orientation. Therefore, even if it does not care about the orientation of the inclined coil itself, the inclined coil can be properly arranged with respect to the base portion only by placing the gripped portion closer to the base portion. It can be positioned in the orientation. Therefore, productivity in the process of attaching the inclined coil to the base portion can be improved. Further, the gripped portion can be brought closer to the base portion side as compared with the case where the gripped portion is at a position that coincides with the central axis of the inclined coil. Therefore, the gripping portion can be reduced in size compared to the case where the gripped portion and the base portion are located at a further distance.

  Next, the conductive member described above will be described with reference to exemplary embodiments. In the following explanation, explanation will be made using the front, rear, left, right and up directions shown in the figure. Each of these directions refers to the direction in which the part appearing in the front view is directed in the hexahedral view of each conductive member, the direction in which the part appearing in the rear view is directed, and the direction in which the part appearing in the left side view is directed. It is a relative direction that defines the direction in which the part appearing on the left and right side views is directed to the right, the direction in which the part appearing in the plan view is directed up, and the direction in which the part appearing in the bottom view is directed down. However, each of these directions is only a direction defined in order to briefly explain the relative positional relationship between the respective parts constituting the conductive member. Therefore, for example, when the conductive members are used, the direction in which the conductive members are directed is arbitrary.

[First embodiment]
First, the first embodiment will be described. A conductive member 10 shown in FIGS. 1A to 1D and 2A to 2F includes a conductive inclined coil 11 and a conductive base 12. . The oblique coil 11 is a metal wire formed in a spiral shape. When the oblique coil 11 is viewed from the axial direction A of the spiral (see FIG. 2C), the outer periphery of the oblique coil 11 has a major axis direction L and a minor axis direction as shown in FIG. And an elliptical outline having S.

  As shown in FIG. 2C, the spiral drawn by the inclined coil 11 is such that the radial direction R of the spiral is inclined at an inclination angle α with respect to the axial direction A of the spiral. As for the radial direction R here, the outer diameter dimension of the inclined coil 11 is the same in the long axis direction L (see FIG. 2B) and the radial direction R (see FIG. 2C). This is the direction. The shape of the spiral drawn by the inclined coil 11 is such that the point that rotates so as to draw a perfect circle along a plane parallel to both the long axis direction L and the radial direction R is a distance corresponding to the rotation angle. The shape corresponds to a locus drawn when the axis is displaced only in the axial direction A.

  The base portion 12 is configured by a metal thin plate formed by press working. The base portion 12 has a joining surface 12A that can be soldered to the surface to be joined, and the above-described inclined coil 11 is attached to a location that is opposite to the joining surface 12A. As shown in FIG. 2 (B), the inclined coil 11 is formed so that the above-described spiral axial direction A and elliptical long-axis direction L are oriented substantially parallel to the joint surface 12A. Mounted on top.

  The base portion 12 is provided with cut-and-raised portions 13, 13, wall portions 14, 14, a sandwiching portion 15, a suction portion 16, and the like. The cut and raised portions 13 and 13 are formed by cutting and raising a part of the base portion 12. The cut-and-raised portions 13, 13 are in contact with a part of the inclined coil 11, so that the inclined coil 11 is displaced with respect to the base portion 12 mainly in the axial direction A (left-right direction in the drawing) by a predetermined amount or more. To regulate.

  The wall portions 14, 14 extend from the base portion 12, and the extended portions are disposed at locations where the extended portions can contact the outer periphery of the inclined coil 11 on both sides of the inclined coil 11. By abutting against a part of the inclined coil 11 with the wall portions 14, 14, the inclined coil 11 is predetermined in the major axis direction L (the front-rear direction in the drawing) with respect to the base portion 12. The above displacement is restricted.

  The sandwiching portion 15 extends from the base portion 12, and the extending portion is disposed on the inner peripheral side of the inclined coil 11. The oblique coil 11 is sandwiched between the sandwiching part 15 and the base part 12 on the outer peripheral side of the oblique coil 11. By sandwiching a part of the oblique coil 11 between the sandwiching part 15 and the base part 12, the oblique coil 11 is mainly in the short axis direction S (the vertical direction in the figure) with respect to the base part 12. Displacement more than a predetermined amount is restricted.

The suction portion 16 is a portion that is sucked by a suction nozzle (not shown) provided in the automatic mounting machine when the conductive member 10 is arranged on the mounting surface of the electronic circuit board using the automatic mounting machine.
When using the conductive member 10 as described above, as shown in FIG. 3, the bonding surface 12A of the base portion 12 has a first member P1 (for example, an electronic circuit board. More specifically, the ground included in the electronic circuit board. It is soldered to the conductor part of the electric potential. At this time, the extending direction front end portion 15A of the sandwiching portion 15 is also soldered to the first member P1.

  Thereby, after soldering, it can suppress that the extending direction front-end | tip part 15A of the clamping part 15 is displaced to the direction spaced apart from the 1st member P1 side. Therefore, it is possible to suppress the oblique coil 11 from being displaced toward the sandwiching portion 15 (upward in the drawing) with the deformation of the sandwiching portion 15.

  In addition, a second member P2 (for example, a metal panel included in the housing) is disposed on the opposite side of the conductive member 10 from the first member P1. The conductive member 10 is sandwiched between the first member P1 and the second member P2. At this time, the inclined coil 11 contacts the second member P2 on the outer periphery of the inclined coil 11 while being elastically deformed. Thereby, the 1st member P1 and the 2nd member P2 are electrically connected.

  In this state, each of the plurality of loops included in the oblique coil 11 contacts the second member P2. Therefore, the inclined coil 11 and the second member P2 are in contact at multiple points. Moreover, the conductive path between the first member P1 and the second member P2 configured between the plurality of contact points matches the direction between the first member P1 and the second member P2 with the axial direction of the coil. Compared to the conductive path configured when the is sandwiched between the first member and the second member, the path length is shortened.

  Therefore, with such a conductive member 10, the conductivity is improved more than the conventional product that forms the conductive path between both ends of the coil, and the impedance value can be easily lowered. Therefore, if a ground countermeasure is performed using such a conductive member 10, an excellent noise reduction effect can be obtained.

  In the conductive member 10, the plurality of loops of the inclined coil 11 are elastically deformed individually and contact the second member P2. Therefore, even when the flatness on the second member P2 side is low, or when the parallelism between the second member P2 side and the conductive member 10 side is low, the conductive member 10 contacts the second member P2 as designed. Can be made.

  Therefore, in the case of such a conductive member 10, unlike the conductive member 10 including a metal piece that contacts the second member P2 on the surface, the inclination of the metal piece with respect to the second member P2 is uneven. Thus, there is no problem that the second member P2 and the metal piece are in line contact or point contact. Therefore, if it is the said electroconductive member 10, dispersion | variation does not arise easily in the contact state with respect to the 2nd member P2, and an electrical connection state can be stabilized.

  Further, in the conductive member 10, the inclined coil 11 is mounted on the base portion 12 so that the axial direction A and the long axis direction L are substantially parallel to the joint surface 12 </ b> A. Therefore, when the pressing force is applied to the oblique coil 11 from the second member P2 as compared with the case where the major axis direction L is inclined with respect to the joining surface 12A, a plurality of loops included in the oblique coil 11 are provided. Each is easy to tilt. Therefore, the repulsive force that acts on the second member P2 from the inclined coil 11 can be reduced.

[Second Embodiment]
Next, a second embodiment will be described. Since the second and subsequent embodiments have many common parts with the first embodiment, the differences from the first embodiment will be described in detail, and overlapping descriptions will be omitted for the common parts.

  The conductive member 20 shown in FIGS. 4A to 4D and FIGS. 5A to 5F includes a conductive inclined coil 21 and a conductive base portion 22. . The oblique coil 21 is the same member as the oblique coil 11 shown in the first embodiment. The base portion 22 has a joining surface 22A that can be soldered, and the above-described oblique coil 21 is attached to a location opposite to the joining surface 22A.

  The base portion 22 is provided with a cut and raised portion 23, wall portions 24 and 24, a caulking portion 25, a suction portion 26, and the like. The cut-and-raised portion 23, the wall portions 24 and 24, and the suction portion 26 have substantially the same configuration as the cut-and-raised portions 13 and 13, the wall portions 14 and 14 and the suction portion 16 of the first embodiment.

  However, the wall portions 24, 24 of the second embodiment restrict the displacement of the inclined coil 21 in the front-rear direction as shown in the figure, and are provided at the front ends of the wall portions 24, 24 in the extending direction. The inclined portions 21A and 24A are configured to restrict the oblique coil 21 from being displaced in the left-right direction in the drawing.

  As shown in FIG. 6, the caulking portion 25 bends a portion extending from the base portion 12, places a part of the inclined coil 21 inside the bending portion, and caulks the bending portion. It is formed. In such a caulking portion 25, by holding a part of the inclined coil 21 inside the curved portion, the inclined coil 21 is restricted from being displaced in the front-rear, left-right, and vertical directions in the drawing. .

  Similarly to the conductive member 10 of the first embodiment, the conductive member 20 as described above is soldered to the first member P1 at the joining surface 22A of the base portion 22 as shown in FIG. The conductive member 20 is sandwiched between the member P2.

  Thereby, the 1st member P1 and the 2nd member P2 are electrically connected. Therefore, if a ground countermeasure is performed using such a conductive member 20, an excellent noise reduction effect can be obtained. In the second embodiment, since the caulking portion 25 as described above is provided, the inclined coil 21 can be firmly held.

[Third embodiment]
Next, a third embodiment will be described. The conductive member 30 shown in FIGS. 7A to 7D and FIGS. 8A to 8E includes a conductive inclined coil 31 and a conductive base portion 32. . The oblique coil 31 is the same member as the oblique coils 11 and 21 shown in the first and second embodiments. The base portion 32 has a solderable joining surface 32A, and the above-described oblique coil 31 is attached to a location opposite to the joining surface 32A.

  The base portion 32 is provided with wall portions 33 and 33 and caulking portions 34 and 34. The wall parts 33 and 33 are the structure substantially the same as the wall parts 14 and 14 of 1st embodiment. The caulking portions 34 and 34 have substantially the same configuration as the caulking portion 25 of the second embodiment. However, as shown in FIG. 9, the third embodiment is different from the second embodiment in that two caulking portions 34 are provided.

  Further, the conductive member 30 of the third embodiment omits the suction portions 16 and 26 provided in the first and second embodiments in order to reduce the area occupied by the conductive member 30 during mounting.

  As in the conductive members 10 and 20 of the first and second embodiments, the conductive member 30 as described above is soldered to the first member P1 at the joining surface 32A of the base portion 32 as shown in FIG. The conductive member 30 is sandwiched between the member P1 and the second member P2.

  Thereby, the 1st member P1 and the 2nd member P2 are electrically connected. Therefore, if a ground countermeasure is performed using such a conductive member 30, an excellent noise reduction effect can be obtained. In the third embodiment, since the two caulking portions 34, 34 as described above are provided, the oblique coil 31 can be firmly held.

[Fourth embodiment]
Next, a fourth embodiment will be described. A conductive member 40 shown in FIGS. 10A to 10D and FIGS. 11A to 11E includes a conductive inclined coil 41 and a conductive base 42. . A gripped portion 43 is added to the inclined coil 41 of the fourth embodiment. The inclined coil 41 and the gripped portion 43 are formed by a single continuous wire, a part of the wire is processed into a shape corresponding to the tilted coil 41, and the remaining part of the wire is formed on the gripped portion 43. It is processed into the corresponding shape. The gripped portion 43 is formed in a spiral shape having a smaller diameter than the inclined coil 41.

  As shown in FIG. 11C, the gripped portion 43 is formed at a position Q2 that is shifted from the center axis position Q1 of the inclined coil 41 toward the base portion 42 by a predetermined distance. The oblique coils 11, 21, 31 of the first, second, and third embodiments are all formed in a shape that draws a spiral for four loops, but the oblique coils 41 of the fourth embodiment are It is formed in a shape that draws a spiral for three loops.

  The base portion 42 has a joining surface 42A that can be soldered, and the above-described oblique coil 41 is attached to a location opposite to the joining surface 42A. The base portion 42 is provided with wall portions 44, 44, a caulking portion 45, a gripping portion 46, a suction portion 47, and the like.

  The wall portions 44 and 44 have hook-shaped portions 44A and 44A, which have the same configuration as the wall portions 24 and 24 and the hook-shaped portions 24A and 24A of the second embodiment. The caulking part 45 and the suction part 47 have the same configuration as the caulking part 25 and the suction part 26 of the second embodiment.

  The gripping part 46 extends from the base part 42. The gripping part 43 is inserted into the inner peripheral side of the substantially C-shaped portion and the C-shaped part is caulked to thereby grip the gripping part 46. It is comprised so that the part 43 can be hold | gripped. By gripping the gripped portion 43 with such a gripping portion 46, displacement of the inclined coil 41 in the front-rear direction, the left-right direction, and the up-down direction in the drawing is restricted.

  As in the conductive members 10, 20, and 30 of the first, second, and third embodiments, the conductive member 40 as described above is soldered to the first member P1 with the joining surface 42A of the base portion 42, as shown in FIG. The conductive member 40 is sandwiched between the first member P1 and the second member P2.

  Thereby, the 1st member P1 and the 2nd member P2 are electrically connected. Therefore, if a ground countermeasure is performed using such a conductive member 40, an excellent noise reduction effect can be obtained. In the fourth embodiment, since the gripped portion 43 and the grip portion 46 as described above are provided, the inclined coil 41 can be firmly held.

  Further, when the gripped portion 43 as described above is added to the tilt coil 41, the tilt coil 41 has directionality. Therefore, when the oblique coil 41 is attached to the base portion 42, the oblique coil 41 is surely in a predetermined orientation.

  Therefore, the inclined coil 41 can be obtained simply by arranging the gripped portion 43 closer to the base portion 42 without worrying about the orientation of the major axis direction of the elliptical cross section of the inclined coil 41. The oblique coil 41 can be positioned with respect to the base portion 42 so that the major axis direction of the elliptical cross section and the joining surface 42A are parallel to each other. Therefore, productivity in the process of attaching the inclined coil 41 to the base portion 42 can be improved.

  Further, the gripped portion 43 can be brought closer to the base portion 42 side as compared with the case where the gripped portion 43 is at a position that coincides with the central axis of the inclined coil 41. Therefore, the gripping portion 46 can be reduced in size compared to the case where the gripped portion 43 and the base portion 42 are located farther apart.

[Fifth embodiment]
Next, a fifth embodiment will be described. A conductive member 50 shown in FIGS. 13A to 13D and FIGS. 14A to 14E includes a conductive inclined coil 51 and a conductive base 52. . The oblique coil 51 of the fifth embodiment is formed in a shape that draws a spiral for two loops, whereby the axial length of the oblique coil 51 is made shorter than in the above-described embodiments.

  The base portion 52 has a solderable joint surface 52A, and the inclined coil 51 is attached to a location opposite to the joint surface 52A. The base portion 52 is provided with wall portions 53 and 53, a caulking portion 54, and the like.

  The wall parts 53 and 53 have hook-like parts 53A and 53A, which have the same configuration as the wall parts 24 and 24 and the hook-like parts 24A and 24A of the second embodiment. The caulking portion 54 is substantially the same as the caulking portion 34 of the third embodiment, but in the fifth embodiment, the base portion 52 is made smaller than the third embodiment by using one caulking portion 54. .

  Similarly to the conductive members 10, 20, 30, and 40 of the first, second, third, and fourth embodiments, the conductive member 50 as described above has a joint surface 52A of the base portion 52 as shown in FIG. The conductive member 50 is sandwiched between the first member P1 and the second member P2 by being soldered to the one member P1.

  Thereby, the 1st member P1 and the 2nd member P2 are electrically connected. Therefore, if a ground countermeasure is performed using such a conductive member 50, an excellent noise reduction effect can be obtained. In the fifth embodiment, the number of loops of the inclined coil 51 is reduced to shorten the axial length, and the above-described caulking portion 54 is integrated into one, so that the occupied area during mounting can be reduced. .

[Sixth embodiment]
Next, a sixth embodiment will be described. A conductive member 60 shown in FIGS. 16A to 16D and FIGS. 17A to 17F includes a conductive inclined coil 61 and a conductive base 62. . The oblique coil 61 is the same member as the oblique coils 11, 21, 31 shown in the first, second, and third embodiments.

  The base portion 62 has a joining surface 62A that can be soldered, and the inclined coil 61 is attached to a location opposite to the joining surface 62A. The base portion 62 is provided with wall portions 63, 63, a sandwiching portion 64, holes 65, 65, 65, 65, a suction portion 66, and the like.

  The walls 63 and 63 have substantially the same configuration as the walls 14 and 14 of the first embodiment. Although the shape of the suction part 66 is different from that of the suction part 16 of the first embodiment, it is functionally equivalent to the suction part 16.

  Unlike the first embodiment, the sandwiching portion 64 has a structure in which both ends of a metal plate separate from the base portion 62 are joined to the base portion 62. The sandwiching portion 64 is disposed on the inner peripheral side of the oblique coil 61 at a stage where at least one end is not joined to the base portion 62 and then joined to the base portion 62.

  Accordingly, the inclined coil 61 is sandwiched between the sandwiching portion 64 and the base portion 62 on the outer peripheral side of the inclined coil 61. By sandwiching a part of the tilt coil 61 between the sandwiching portion 64 and the base portion 62, the tilt coil 61 is displaced with respect to the base portion 62 mainly by a predetermined amount or more in the vertical direction in the figure. It is regulated.

  The holes 65, 65, 65, 65 are each fitted with a part of the inclined coil 61, so that the inclined coil 61 is displaced by a predetermined amount or more in the left-right direction in the drawing relative to the base portion 62. Is regulated.

  Similarly to the conductive member 10 of the first embodiment, the conductive member 60 as described above is soldered to the first member P1 at the joining surface 62A of the base portion 62 as shown in FIG. The conductive member 60 is sandwiched between the member P2. Thereby, the 1st member P1 and the 2nd member P2 are electrically connected. Therefore, if a ground countermeasure is performed using such a conductive member 60, an excellent noise reduction effect can be obtained.

  In the sixth embodiment, the inclined coil 61 can be firmly held by the sandwiching portion 64 as described above. Further, when the oblique coil 61 receives a pressing force from the second member P2 by the holes 65, 65, 65, 65, each loop of the oblique coil 61 can be prevented from sliding in the left-right direction. It is possible to appropriately maintain the position at the position as designed.

[Other Embodiments]
As described above, the conductive member has been described with reference to the exemplary embodiment, but the present invention is not limited to the exemplary embodiment described above, and within the scope not departing from the technical idea of the present invention, It can be implemented in various forms.

  For example, the hole 65 shown in the sixth embodiment is a hole that penetrates the base portion 62, but instead of this, even if a recess that does not penetrate (that is, a bottomed hole) is provided, It can suppress that each loop of an inclination coil slips in the left-right direction.

  Moreover, in the said embodiment, although the gradient coil which draws the spiral for 2-4 loop was illustrated, the number of loops of a gradient coil is not specifically limited. In the above-described embodiment, a plurality of types of structures are exemplified as the structure for holding the oblique coil on the base portion. However, the plurality of types of structures may be combined in any way.

  Moreover, although the electrically-conductive member 60 of the said 6th Embodiment was provided with the wall part 63, it is arbitrary whether the wall part 63 is provided. For example, even when the wall portion 63 is not provided, the inclined coil 61 can be prevented from sliding in the front-rear and left-right directions by the sandwiching portion 64 and the hole 65. Therefore, such a configuration may be adopted.
