FIG. 9 and 10 are diagrams showing a terminal pin insertion step (step S10) in which the terminal pins 11A and 11B are inserted into the support holes 12A and 12B of the terminal support portion 10. FIG. FIGS. 11 and 12 are views showing a state in which the terminal pins 11A and 11B are inserted into the support holes 12A and 12B when conducting the wire winding step (step S20) for winding the wire 5 around the bobbin 6. FIG. 13 and 14 are views showing a state where the winding of the conducting wire 5 around the bobbin 6 and the support of the terminal pins 11A and 11B to the terminal support portion 10 are completed, that is, a state where the manufacture of the coil body 2 is completed. . FIG. 15 is a diagram showing a lead wire support process for supporting the lead wires 14A and 14B on the fixing plate 3. As shown in FIG. 16 and 17 are diagrams showing a fixing plate attaching step (step S60) for attaching the fixing plate 3 supporting the lead wires 14A and 14B to the bobbin 6.

  First, as shown in FIGS. 9 and 10, the terminal pin 11A and the terminal pin 11B are inserted into the support hole 12A and the right terminal support portion 10B support hole 12B of the left terminal support portion 10A, respectively (terminal pin insertion step S10). . 9 is a perspective view showing the terminal pin insertion step (terminal pin insertion step S10), and the upper part (A) of FIG. 10 is a partial front view of the terminal pin insertion step as seen from the front. The lower part (B) is a partial plan view of the terminal pin insertion process as viewed from above.

  The terminal pin 11A is inserted into the support hole 12A from the left outer surface 22A side of the left terminal support portion 10A with the annular portion 23A facing the fitting portion 17 side. Similarly, the terminal pin 11B is inserted into the support hole 12B from the right outer surface 22B side of the right terminal support portion 10B with the annular portion 23B facing the fitting portion 17 side. Thus, the terminal pins 11A and 11B can be smoothly inserted into the support holes 12A and 12B by inserting the terminal pins 11A and 11B into the support holes 12A and 12B from the ring portions 23A and 23B. .

  In the terminal pin insertion step S10, as shown in FIGS. 11 and 12, the terminal pin 11A is inserted so that the one end 16A protrudes from the support hole 12A to the left outer surface 22A. Similarly, the terminal pin 11B is inserted so that the one end 16B protrudes from the support hole 12B to the right outer surface 22B.

  The terminal pins 11A and 11B are bent at positions deviated from the center of the terminal pins 11A and 11B to the other end side. That is, each length from the annular portion 23A to both ends of the terminal pin 11A is longer at the one end portion 16A side than at the other end portion side. Similarly, the terminal pin 11B has a shape in which each length from the annular portion 23B to both ends is longer on the one end 16B side than on the other end side. Therefore, the terminal pin 11A can be supported by the left terminal support portion 10A so that only the one end portion 16A side protrudes from the left outer surface 22A. Similarly, the terminal pin 11B can be supported by the right terminal support portion 10B so that only the one end portion 16B side protrudes from the right outer surface 22B.

  Next, with the terminal pins 11A and 11B supported by the terminal support 10 as shown in FIGS. 11 and 12, the conductor 5 is wound around the bobbin 6 using an automatic winding machine (not shown). The coil body 2 is manufactured by turning (conductive wire winding step S20). In the conductor winding step S20, the bobbin 6 to which the temporary fixing jig is attached is fixed to the fixing jig of the automatic winding machine, and the conductor 5 is wound around the body portion 8 of the bobbin 6. At this time, the bobbin 6 rotates together with the fixing jig. In this conducting wire winding step S20, the winding of the conducting wire 5 around the trunk portion 8 is automatically performed by an automatic winding machine. When the winding of the conducting wire 5 around the trunk portion 8 is completed, the bobbin 6 with the temporary fixing jig attached is removed from the fixing jig of the automatic winding machine.

  Then, the leading end 5A of the conducting wire 5 wound around the bobbin 6 is bound to the one end 16A side of the terminal pin 11A, the trailing end 5B of the conducting wire 5 is tied to the one end 16B side of the terminal pin 11B, and the conducting wire 5 and terminal pins 11A and 11B are connected (conductor connection step S30). In this conductive wire connecting step S30, dip soldering is performed on the binding portion, and the front end portion 5A and the rear end portion 5B of the conductive wire 5 are securely fixed to the terminal pins 11A and 11B.

  As described above, the terminal pins 11A and 11B protrude from the left outer surface 22A and the right outer surface 22B only at the one end portions 16A and 16B side. Thus, by projecting only the one end portions 16A and 16B of the terminal pins 11A and 11B from the left outer surface 22A and the right outer surface 22B, both ends of the terminal pins 11A and 11B are left outer surface 22A and right outer surface 22B. Compared with the case where the lead wire 5 protrudes from the terminal pins 11A and 11B, the leading end portion 5A and the rear end portion 5B of the conducting wire 5 can be easily performed.

  That is, when the other end portion is projected in addition to the one end portions 16A and 16B of the terminal pins 11A and 11B, when the conducting wire 5 is tangled to the one end portions 16A and 16B side, the conducting wire 5 is connected to the other end portion. It is necessary to avoid the other end to avoid entanglement. On the other hand, it is not necessary to project only the one end portions 16A and 16B.

  Next, the terminal pins 11A and 11B are moved to the fitting portion 17 side, and the annular portions 23A and 23B of the terminal pins 11A and 11B are projected from the fitting portion 17 by a predetermined amount as shown in FIGS. (Projection step S40). A slit 10SA is formed in the left outer surface 22A, which is the left side surface of the left terminal support portion 10A. The slit 10SA is formed from the opening in the left outer surface 22A of the support hole 12A to the rear end surface of the front flange 9A, and the support hole 12A and the rear end surface of the front flange 9A communicate with each other via the slit 10SA. is doing. Further, a slit 10SB similar to the slit 10SA is formed on the right outer surface 22B, which is the right side surface of the right terminal support portion 10B, and the support hole 12B and the rear end surface of the front collar portion 9A communicate with each other via the slit 10SB. ing. Subsequent to the above-described protruding step S40, the conductor 5 connected to the terminal pin 11A is pulled out to the rear end surface of the front flange portion 9A through the slit 10SA, and the conductor 5 connected to the terminal pin 11B is similarly used. Then, it is pulled out to the rear end surface of the front collar portion 9A through the slit 10SB. Then, the exterior tape 7 is wound by an automatic machine so as to cover the entire outer peripheral surface of the conducting wire 5 wound around the trunk portion 8.

  The coil body 2 shown in FIGS. 13 and 14 is completed through the above steps. In addition, each process, such as terminal pin insertion process S10, conducting wire winding process S20, conducting wire connection process S30, protrusion process S40, may be performed automatically by an automatic machine, or may be performed manually.

  Then, as shown in FIG. 5, the bobbin 6 (coil body 2) is accommodated in the frame 4 in the direction of the arrow and fixed to the frame 4 (fixing step S50). In the fixing step S50, the frame 4 is fixed to the bobbin 6 by an automatic machine. These fixations may be performed manually.

  In parallel with or before or after each of the above steps (steps S10 to S50), as shown in FIG. 15, the lead wires 14A and 14B are supported on the fixing plate 3 (lead wire support step). The lead wires 14A and 14B are in a state in which the resin coating on the distal end side is removed in advance so that the conductive wire portions 15A and 15B are exposed at the distal ends.

  The lead wires 14A and 14B are inserted into the lead wire holding holes 29A and 29B from the opening portions 32A and 32B in front of the lead wire holding holes 29A and 29B with the conductive wire portions 15A and 15B facing the fitting direction (rear). Is done. The covering portions 33A and 33B of the lead wires 14A and 14B are formed to be slightly thicker than the diameters of the lead wire holding holes 29A and 29B. In addition, dividing grooves 34A and 34B are formed in the lead wire holding holes 29A and 29B. Therefore, the lead wires 14A and 14B are supported in a state where a holding force is received in the lead wire holding holes 29A and 29B.

  That is, the lead wires 14 </ b> A and 14 </ b> B are held by the fixed plate 3 in a state where it is difficult to move in the front-rear direction. As shown in FIG. 16, the lead wires 14A and 14B have the lengths of the conductor portions 15A and 15B and the insertion amounts into the lead wire holding holes 29A and 29B so that the conductor portions 15A and 15B face the recesses 26A and 26B. It is prescribed.

  Subsequently, as shown in FIGS. 16 and 17, the fixing plate 3 is attached to the coil body 2 (fixing plate attaching step S60). FIG. 16 shows a plan view of the fixing plate 3 and the coil body 2 in a state before the fixing plate 3 is attached to the coil body 2. The upper part (A) of FIG. 17 shows a plan view of the fixing plate 3 and the coil body 2 in a state after the fixing plate 3 is attached to the coil body 2. The lower part (B) of FIG. 17 shows a schematic cross-sectional view taken along a cutting line BB shown in FIG.

  In the fixing plate attaching step S <b> 60, the fixing plate 3 is fitted into the fitting portion 17 from the opening 24 formed in front of the fitting portion 17 with the side where the engaging portion 25 is provided facing rearward. The fixed plate 3 is inserted into the fitting portion 17 with the fixed plate left outer surface 22A and the fixed plate right outer surface 22B guided in the vertical and horizontal directions by the left inner surface 20A and the right inner surface 20B.

  By the way, the predetermined protrusion amount of the terminal pin 11A in the protrusion step S20 described above is such that when the fixing plate 3 is inserted into the fitting portion 17, the conducting wire portion 15A is connected to the inner peripheral side (the annular portion 23A and the annular portion 23A). The projecting amount is set such that the annular portion 23A can abut against the wall portion 27A of the fixing plate 3 and the left inner side surface 20A. Similarly, when the terminal pin 11B is inserted into the fitting portion 17, the lead wire portion 15B is located on the inner peripheral side of the annular portion 23B (between the annular portion 23B and the right inner side surface 20B). The predetermined protrusion amount of the terminal pin 11B in the protrusion step S20 is set so that the ring portion 23B can pass through and can contact the wall portion 27B of the fixing plate 3.

  The vertical widths of the terminal pins 11A and 11B are set to be narrower than the vertical width of the recesses 26A and 26B (see FIGS. 3, 6, and 7). Therefore, when the fixing plate 3 is inserted into the fitting portion 17, the terminal pins 11A and 11B enter the recesses 26A and 26B from the openings 28A and 28B as the fixing plate 3 moves in the insertion direction. Then, the conductor portion 15A enters the inner peripheral side of the annular portion 23A, that is, between the left side of the annular portion 23A and the left inner side surface 20A. Moreover, the conducting wire portion 15B also enters the inner peripheral side of the annular portion 23B, that is, between the right side of the annular portion 23B and the right inner surface 20B.

  Prior to the fixing plate attaching step S60, a taper pin is inserted into the annular portions 23A and 23B of the terminal pins 11A and 11B, and a process of widening the inner periphery of the annular portions 23A and 23B may be performed. . By performing such processing and widening the inner circumferences of the annular portions 23A, 23B, when attaching the fixing plate 3 to the coil body 2, the conductor portions 15A, 15B are inserted into the annular portions 23A, 23B. It is easy to (enter).

  When the fixing plate 3 is moved in the fitting direction, the annular portion 23A is pushed leftward by the wall portion 27A inclined leftward from the rear toward the front. That is, the terminal pin 11 </ b> A is moved to the left as the fixing plate 3 moves in the fitting direction. Then, as shown in FIG. 17B, the annular portion 23A and the conductor portion 15A are sandwiched between the wall portion 27A of the fixing plate 3 and the left inner side surface 20A of the left terminal support portion 10A. 23A and the lead wire portion 15A are in contact with each other, and the lead wire 14A and the terminal pin 11A are electrically connected.

  In the annular portion 23A, a portion facing the conductor portion 15A on the right side of the conductor portion 15A mainly contacts the conductor portion 15A as the first contact portion 35A. The left inner surface 20A is located to the left of the conductor portion 15A. Therefore, the leftward movement of the conductor portion 15A is prevented by the left inner surface 20A. Therefore, the annular portion 23A is pushed leftward from the right side of the conductor portion 15A by the wall portion 27A, so that the contact between the annular portion 23A and the conductor portion 15A is ensured.

  Similarly, when the fixing plate 3 is fitted into the fitting portion 17, the terminal pin 11 </ b> B and the annular portion 23 </ b> B are circular between the wall portion 27 </ b> B of the fixing plate 3 and the right inner surface 20 </ b> B of the right terminal support portion 10 </ b> B. The ring portion 23B and the conductor portion 15B are sandwiched, and the annular portion 23B and the conductor portion 15B are in contact with each other. Thereby, the lead wire 14B and the terminal pin 11B are electrically connected.

  In the annular portion 23B, a portion facing the conductor portion 15B on the left side of the conductor portion 15B mainly contacts the conductor portion 15B as the first contact portion 35B. The rightward movement of the conductor portion 15B is also prevented by the right inner side surface 20B. Therefore, the annular portion 23B is pushed rightward from the left side of the conductor portion 15B by the wall portion 27B, so that the annular portion 23B and the conductor are connected. Contact with the part 15B is ensured.

  The inclination of the wall portions 27A and 27B, the amount of movement of the fixing plate 3 and the like are such that the engaging portion 25 of the fixing plate 3 engages with the bridge portion 19 and the fixing plate 3 is fixed in the front-rear direction. Between the annular portion 23A and the conductor portion 15A sandwiched between the left inner side surface 20A and the annular portion 23B and the conductor portion 15B sandwiched between the wall portion 27B and the right inner surface 20B. It is set so that the contact of is surely performed. The coil member 1 is manufactured through the above processes.

  In the state where the fixing plate 3 is fitted to the fitting portion 17, the terminal pins 11A are so disposed that the one end portions 16A, 16B of the terminal pins 11A, 11B are completely accommodated in the back of the support holes 12A, 12B. , 11B is set to have a length on one end 16A, 16B side. Thereby, the part where the conducting wire 5 is entangled can be arranged in the support holes 12A and 12B, the object collides with the tying part and the tying part is damaged, and the terminal pins 11A and 11B and the conducting wire 5 are connected. It is possible to prevent poor connection.

  As described above, in the coil member 1 according to the embodiment of the present invention, the coil body 2 having the conducting wire 5 and the bobbin 6 around which the conducting wire 5 is wound, and the tip portion 5A of the conducting wire 5 are connected. A terminal pin 11A as a terminal part, a terminal pin 11B as a terminal part to which the rear end part 5B of the conducting wire 5 is connected, a left terminal support part 10A that supports the terminal pin 11A, and a right terminal that supports the terminal pin 11B The left terminal support part 10A and the right terminal support part 10B are provided on the bobbin 6 with a space therebetween. The lead wire 14A is connected to the terminal pin 11A, and the lead wire 14B is connected to the terminal pin 11B.

  The two lead wires 14A and 14B are supported by the fixing plate 3, and the fixing plate 3 is fitted into a fitting portion 17 formed between the left terminal support portion 10A and the right terminal support portion 10B. Thus, the bobbin 6 is attached. The fixing plate 3 is formed with a wall portion 27A and a wall portion 27B.

  The wall portion 27A is formed such that a space between the fixing plate 3 and the left inner side surface 20A becomes narrower toward the front which is the reverse direction to the rear which is the fitting direction of the fixing plate 3 to the fitting portion 17. The wall portion 27B is also formed so that the space between the wall portion 27B and the right inner surface 20B becomes narrower toward the front. Further, the terminal pin 11A is a part of the terminal pin 11A from the left inner side surface 20A, which is one of the surfaces of the left terminal support portion 10A and the right terminal support portion 10B facing each other, to the fitting portion 17 side. Is supported by the left terminal support portion 10A so as to protrude.

  Further, the terminal pin 11B is also a part of the terminal pin 11B from the right inner side surface 20B which is the other surface of the surfaces where the left terminal support portion 10A and the right terminal support portion 10B face each other to the fitting portion 17 side. Is supported by the right terminal support portion 10B so as to protrude. Each of the left terminal support portions 10A, 10B can change the amount of protrusion of the annular portions 23A, 23B, which are protrusions protruding toward the fitting portion 17 of the terminal pins 11A, 11B. , 11B are movably supported.

  The annular portions 23A and 23B protruding to the fitting portion 17 side of the terminal pins 11A and 11B are arranged between the lead wires 14A and 14B and the wall portions 27A and 27B, and the lead wires 14A and 14B. First contact portions 35A and 35B as first contact portions that can come into contact with each other.

  Thus, by configuring the coil member 1, the lead wires 14 </ b> A and 14 </ b> B can be connected to the conducting wire 5 by a simple operation of attaching the fixing plate 3 supporting the lead wires 14 </ b> A and 14 </ b> B to the bobbin 6. . Further, since the annular portion 23A is pushed leftward from the right side of the conducting wire portion 15A by the wall portion 27A, the annular portion 23A and the conducting wire portion 15A come into contact with each other, so that the contact between the terminal pin 11A and the lead wire 14A is prevented. It can be certain. As for the contact between the terminal pin 11B and the lead wire 14B, the annular portion 23B is brought into contact with the conductor portion 15B by pressing the annular portion 23B to the right from the left side of the conductor portion 15B by the wall portion 27B. Reliable contact can be achieved.

  The left terminal support portion 10A and the right terminal support portion 10B are opposed to each other on the fitting portion 17 side, and the left inner side as a support portion facing surface that contacts the left outer surface 22A and the right outer surface 22B of the fixing plate 3 The distance between the side surface 20A and the right inner surface 20B is configured to be narrower in the direction away from the bobbin 6, that is, upward. Further, the interval between the left outer surface 22 </ b> A and the right outer surface 22 </ b> B as the fixing plate side surface of the fixing plate 3 is also configured to become narrower in the direction away from the bobbin 6.

  In this way, by configuring the coil member 1, the fixing plate 3 can be held by the fitting portion 17 so as not to move in the left-right direction and the up-down direction. For this reason, it is possible to prevent the fixing plate 3 from moving up and down or left and right, and the contact state between the terminal pins 11A and 11B and the lead wires 14A and 14B cannot be ensured.

  The annular portions 23A and 23B as the protruding portions have a circular shape on the inner periphery. And the cross-sectional shape of conducting-wire part 15A, 15B which contacts 1st contact part 35A, 35B of annular part 23A, 23B is exhibiting the circle.

  Therefore, it is possible to widen the contact area between the conductor portions 15A and 15B and the annular portions 23A and 23B.

  When the curvatures on the inner peripheral sides of the annular portions 23A and 23B are different from the curvatures of the conductor portions 15A and 15B, the contact portions in the circumferential direction are theoretically point contacts. However, when the annular portions 23A and 23B are pushed toward the conductor portions 15A and 15B, the annular portions 23A and 23B are deformed and come into line contact with the conductor portions 15A and 15B. For this reason, the annular portions 23A and 23B have an annular shape, and the conducting wire portions 15A and 15B have a cylindrical shape, so that the number of portions in line contact increases, and the electrical connection between the conducting wire 5 and the lead wires 14A and 14B is increased. Contact can be ensured.

  The terminal pin 11A is inserted into a support hole 12A formed in the left terminal support portion 10A and supported by the left terminal support portion 10A. Further, the terminal pin 11B is inserted into a support hole 12B formed in the right terminal support portion 10B and supported by the right terminal support portion 10B.

  Thus, by comprising the coil member 1, the terminal pins 11A and 11B support the terminal pins 11A and 11B with respect to the terminal support part 10 by a simple operation of inserting them into the support holes 12A and 12B, respectively. be able to. Further, the terminal pins 11A and 11B are inserted into the support holes 12A and 12B and supported by the terminal support portion 10, thereby moving the ring portions 23A and 23B in the direction of changing the amount of protrusion toward the fitting portion 17 side. It can be done easily.

  As described above, in the method of manufacturing the coil member 1 according to the embodiment of the present invention, one end portion of the terminal pin 11A protrudes from the left outer surface 22A that is the side surface opposite to the fitting portion 17, and the terminal pin Similarly, the terminal pins 11A and 11B are inserted into the support holes 12A and 12B of the terminal support portion 10 so that one end portion thereof protrudes from the right outer surface 22B which is the side surface opposite to the fitting portion 17 in the same manner. A part insertion step (step S10), a winding step (step S20) in which the conductor 5 is wound around the bobbin 6 to form the coil body 2, and the tip 5A of the conductor 5 is connected to the one end 16A side of the terminal pin 11A. Together with the lead wire connecting step (S30) for connecting the rear end portion 5B of the lead wire 5 to the one end portion 16B side of the terminal pin 11B, and the first connecting portions 35A, 35B of the terminal pins 11A, 11B to which the lead wire 5 is connected. , Fitting portion 17 The fixing plate 3 is fitted to the fitting portion 17 in a state in which the lead wire 14A, 14B is disposed between the wall portions 27A, 27B and the first contact portions 35A, 35B. A fixing plate attaching step (S60) for fitting from the direction and attaching the fixing plate 3 to the bobbin 6.

  Thus, by manufacturing the coil member 1, the lead wires 14 </ b> A and 14 </ b> B can be connected to the conductive wire 5 by a simple operation of attaching the fixing plate 3 supporting the lead wires 14 </ b> A and 14 </ b> B to the bobbin 6. .

  In the coil member 1 described above, it is preferable to perform a solder dipping process on the conductor portions 15A and 15B which are the tip portions of the lead wires 14A and 14B connected to the terminal pins 11A and 11B. By performing the solder dipping process, it is possible to prevent the core wires of the conductor portions 15A and 15B from being separated and to increase the rigidity of the conductor portions 15A and 15B. Thus, when the conductor portions 15A and 15B are sandwiched between the terminal pins 11A and 11B and the left inner side surface 20A and the right inner side surface 20B, the contact state between the terminal pins 11A and 11B is ensured. can do.

  Moreover, you may wind the conducting wire helically around conducting-wire part 15A, 15B (for example, thickness of 1/10 diameter of conducting-wire part 15A, 15B) thinner than conducting-wire part 15A, 15B. Thus, by winding a thin conducting wire around the conducting wire portions 15A and 15B, a hook can be created between the conducting wire wound around the conducting wire portions 15A and 15B and the annular portions 23 and 23B. The portions 15A and 15B can be made difficult to come off from the annular portions 23 and 23B.

  As shown in FIGS. 18 to 22 and the like, the left terminal support portion 53A and the right terminal support portion 53B each have a substantially rectangular parallelepiped shape that is flattened upward and downward. The left terminal support part 53A and the right terminal support part 53B have a fitting part 54 (see FIGS. 20, 21, etc.) in which the fixing plate 51 is fitted between the left terminal support part 53A and the right terminal support part 53B. Are arranged on the left and right of the front flange 9A. The left terminal support portion 53A and the right terminal support portion 53B have a symmetrical shape. The left terminal support portion 53A and the right terminal support portion 53B have extension portions 55A and 55B that extend so as to protrude forward from the front end surface of the front collar portion 9A. Further, the rear end portions (end surfaces) of the left terminal support portion 53A and the right terminal support portion 53B are formed to be flush with the rear end surface of the front flange portion 9A.

  As shown in FIGS. 21, 22, etc., a bridge portion 56 is passed between the left terminal support portion 53A and the right terminal support portion 53B. The bridge portion 56 functions to guide the guide receiving portion 65 of the fixing plate 51 so that the fixing plate 51 can be guided to a predetermined fitting position when the fixing plate 51 is fitted to the fitting portion 54. Have

  The left inner side surface 57A and the right inner side surface 57B as the support portion facing surfaces facing the fitting portion 54 of the left terminal support portion 53A and the right terminal support portion 53 are arranged to face each other in parallel. That is, the space forming the fitting portion 54 has a rectangular parallelepiped shape. Therefore, as shown in FIG. 34, the fixing plate 51 can be inserted into the fitting portion 54 from the upper front side. The left inner surface 57A and the right inner surface 57B are, when the fixing plate 51 is fitted to the fitting portion 54, the fixing plate left side surface 58A and the fixing plate right side as the fixing plate side surfaces that are the left and right side surfaces of the fixing plate 51. It contacts the surface 58B.

  The terminal support portion 53 is provided with support holes 59A and 59B for supporting the terminal plates 52A and 52B.

  The terminal boards 52A and 52B have a form in which a long and narrow rectangular flat stainless steel plate is bent in a U shape. The bending direction is a direction in which the wide surface of the plate is folded back. The leading end 5A of the conducting wire 5 is connected to the one end 61A side of the terminal plate 52A, and the trailing end 5B of the conducting wire 5 is connected to the one end 61B side of the terminal plate 52B.

  As shown in FIG. 23, the shape of the opening 62 of the support hole 59A is such that the terminal plate 52A is oriented with the width direction (short direction) of the terminal plate 52A in the front-rear direction and the bending direction (bent terminal plate). The shape can be inserted in a state in which the direction in which 52A overlaps is directed vertically. The support hole 59A has a shape in which the height of the opening 62 increases from the rear toward the front. Therefore, in the support hole 59A, when the width in the front-rear direction of the upper surface 62A and the bottom surface 62B in the hole (in the opening 62) is compared, the width M1 in the front-rear direction of the upper surface 62A is greater than the width M2 in the front-rear direction of the bottom surface 62B. Is also wide (long). The support hole 59B has a symmetrical shape with the support hole 59A.

  The support holes 59A and 59B have a size and the like of the opening 62 so that a holding force that does not cause the terminal plates 52A and 52B to fall off due to their own weight acts on the terminal plates 52A and 52B. The terminal plates 52A and 52B are inserted into the support holes 59A and 59B so that the annular portions 63A and 63B, which are bent portions, face the fitting portion 54 side. The annular portions 63A and 63B formed by the terminal plates 52A and 52B are wide in the front-rear direction and have a semi-annular cylindrical shape.

The upper stage (A) of FIG. 24 is a perspective view of the fixed plate 51 as viewed from the front, and the lower stage (B) is a perspective view of the fixed plate 51 as viewed from the rear. The first stage (A) in FIG. 25 shows a plan view of the fixing plate 51, the second stage (B) shows a front view, and the third stage (C) shows a side view. Similarly, the fourth stage (D) shows a rear view of the fixing plate 51, and the fifth stage (E) shows a bottom view.

  The fixing plate 51 has a shape that can be fitted into the fitting portion 54 from the opening 64 in front of the fitting portion 54 toward the rear. The left and right side surfaces 58A and 58B of the fixing plate 51 and the left side surface 57A of the left terminal support portion 53A and the right inner side surface 57B of the right terminal support portion 53B are the left and right side surfaces of the fixing plate 51. It forms so that it can mutually contact | abut when it fits into the fitting part 54. FIG. Therefore, the fixing plate 51 can be accommodated in the fitting portion 54 without play in the left-right direction.

  The vertical thickness of the fixing plate 51 and the vertical thickness of the terminal support portion 53 are substantially the same. When the fixing plate 51 is fitted to the fitting portion 54, the upper and lower surfaces of the fixing plate 51 and the terminal support are fixed. The upper and lower surfaces of the portion 53 are substantially flush. On the rear side of the fixed plate 51, a guide receiving portion 65 that receives a guide of the bridge portion 56 when the fixed plate 51 is fitted into the fitting portion is provided. The guide receiving portion 65 is composed of two upper and lower plate-like bodies 65A and 65B. By passing the bridge portion 56 through the gap 65C between the plate-like body 65A and the plate-like body 65B, the fixing plate 51 can be guided to the bridge portion 56.

  Concave portions 66 </ b> A and 66 </ b> B that are recessed upward from the lower side are formed on the left and right sides of the front and rear sides of the fixing plate 51. The wall portion 67A, which is the right side surface of the recess 66A, and the wall portion 67B, which is the left side surface of the recess 66B, have the same spacing in the front-rear direction, and the spacing from the bottom toward the top increases. Is formed. That is, the wall portion 67A is configured to be inclined so that the distance from the left inner side surface 57A becomes narrower toward the upper side, which is the opposite direction to the lower direction, which is the fitting direction of the fixing plate 51 to the fitting portion 54. . Further, the wall portion 67B is also configured to be inclined so that the interval with the left inner side surface 57A becomes narrower toward the upper side, which is the opposite direction to the fitting direction of the fixing plate 51 to the fitting portion 54.

  Lead wire holding holes 68A and 68B through which the lead wires 14A and 14B are inserted are formed on the left and right sides of the fixing plate 51. The lead wire holding hole 68 </ b> A is disposed so as to come out from the front end surface 69 of the fixing plate 51 to the left side of the front end of the wall portion 67 </ b> A. Further, the lead wire holding hole 68B is also arranged so as to come out to the right of the front end of the wall portion 67B from the front end surface 69 of the fixing plate 51 toward the rear.

  As shown in FIGS. 18 to 21, the lead wires 14A and 14B are supported by the fixing plate 51 in a state of being inserted into the lead wire holding holes 68A and 68B from the front. The lead wires 14A and 14B have their leading ends (front ends) from which the resin coating of the lead wires 14A and 14B is removed, and the lead wires 15A and 15B (see FIG. 14) are exposed. The lead wires 14A and 14B are supported by the fixing plate 51 so that the conductive wire portions 15A and 15B are positioned in the recesses 66A and 66B.

  That is, the lead wire portion 15A of the lead wire 14A passed through the lead wire holding hole 68A is disposed on the left side of the wall portion 67A, and the lead wire portion 15B of the lead wire 14B passed through the lead wire holding hole 68B is Arranged on the right side of the part 67B. Then, when the fixing plate 51 is attached to the bobbin 6, the conducting wire portions 15A and 15B are electrically connected to the terminal plates 52A and 52B, so that the conducting wire 5 and the lead wires 14A and 14A are connected via the terminal plates 52A and 52B. 14B is electrically connected. The lead wire holding holes 68A and 68B are formed with split grooves 70A and 70B that pass through the lower surface of the fixing plate 51.

  By forming the split grooves 70A and 70B, the widths in the left and right directions of the lead wire holding holes 68A and 68B can be changed elastically. Therefore, the holding force for holding the lead wires 14A, 14B on the fixing plate 51 is configured by making the diameters of the lead wires 14A, 14B (diameter of the covering portion) slightly larger than the diameters of the lead wire holding holes 68A, 68B. Can be generated. That is, the fixing plate 51 can hold the lead wires 14A and 14B so as not to move in the front-rear direction.

  An engaging portion 76 is provided on the lower surface of the fixed plate 51 to engage with the lower surfaces of the left terminal support portions 53A and 53B when the fixed plate 51 is fitted into the fitting portion 54. When the fixing plate 51 is fitted into the fitting portion 54, the engaging portion 76 engages with the lower surfaces of the left terminal support portions 53A and 53B, so that the fixing plate 51 is removed upward from the fitting portion 54. You can avoid it.

  Next, a method for manufacturing the coil member 50 will be described with reference to FIGS.

  FIG. 26 is a flowchart showing the manufacturing process of the coil member 50. FIG. 27 to FIG. 36 are diagrams showing the manufacturing process of the coil member 50. 27 and 28 are diagrams showing a terminal pin insertion step (step S110) in which the terminal plates 52A and 52B are inserted into the support holes 59A and 59B of the terminal support portion 53. FIG. 29 and 30 are views showing a state in which the terminal plates 52A and 52B are inserted into the support holes 59A and 59B when the conducting wire winding step (step S120) for winding the conducting wire 5 around the bobbin 6 is performed. 31 and 32 are views showing a state where the winding of the conducting wire 5 around the bobbin 6 and the support of the terminal plates 52A and 52B to the terminal support portion 53 are completed, that is, a state where the manufacture of the coil body 2 is completed. . FIG. 33 is a diagram showing a lead wire support process in which the lead wires 14A and 14B are supported by the fixing plate 51. 34 to 36 are diagrams showing a fixing plate attaching step (step S160) for attaching the fixing plate 51 on which the lead wires 14A and 14B are supported to the bobbin 6. FIG.

  First, as shown in FIGS. 27 and 28, the terminal plate 52A and the terminal plate 52B are inserted into the support hole 59A of the left terminal support portion 53A and the support hole 59B of the right terminal support portion 53B, respectively (terminal pin insertion step S110). ). 27 is a perspective view showing the terminal board insertion step (terminal board insertion step S110), and the upper part (A) of FIG. 28 is a partial front view of the terminal board insertion step as seen from the front. The lower part (B) is a partial plan view of the terminal board insertion process as viewed from above.

  The terminal plate 52A is inserted into the support hole 59A from the left outer surface 60A side of the left terminal support portion 53A with the annular portion 63A facing the fitting portion 54 side. Similarly, the terminal plate 52B is inserted into the support hole 59B from the right outer surface 60B side of the right terminal support portion 53B with the annular portion 63B facing the fitting portion 54 side. Thus, by inserting the terminal plates 52A and 52B into the support holes 59A and 59B from the ring portions 63A and 63B, the terminal plates 52A and 52B can be smoothly inserted into the support holes 59A and 59B. .

  As shown in FIGS. 22 and 23, the terminal plate 52A is supported in the support hole 59A so that the front side is disposed higher than the rear side. That is, the terminal plate 52A is supported in the support hole 59A in a state where it is inclined upward from the rear to the front. The width of the terminal plate 52A in the front-rear direction is wider than the width M2 of the bottom surface 62B of the support hole 59A.

  Therefore, the terminal plate 52A can be inserted into the support hole 59A by inclining the front side so as to be disposed above the rear side, and as described above in the support hole 59A. In addition, it is supported in a state inclined upward from the rear to the front. The opening 62 of the support hole 59A has a height from the rear toward the front so that the terminal plate 52A can be inserted in such a manner that the front side is inclined so as to be disposed above the rear side. It has a higher shape. Similarly to the terminal plate 52A, the terminal plate 52B is supported in the support hole 59B while being inclined upward from the rear to the front.

  The terminal plate 52A is supported in the support hole 59A in a state where the terminal plate 52A is inclined upward from the rear to the front, so that the opening 72A of the annular portion 63A of the terminal plate 52A is an opening directed obliquely upward to the front. It becomes. Further, the terminal plate 52B is also supported in the support hole 59B while being inclined upward from the rear to the front, so that the opening 72B (see FIG. 23) of the annular portion 63B of the terminal plate 52B The opening is directed obliquely upward.

  In the terminal board insertion step S110, as shown in FIGS. 29 and 30, the terminal board 52A is inserted so that the one end 61A protrudes from the support hole 59A to the left outer surface 60A. Similarly, the terminal plate 52B is inserted so that the one end 61B protrudes from the support hole 59B to the right outer surface 60B. The terminal plates 52A and 52B are bent at positions deviated from the center of the terminal plates 52A and 52B to the other end side.

  That is, each length from the annular portion 63A to both ends of the terminal plate 52A is longer on the one end 61A side than on the other end side. Similarly, the length of the terminal plate 52B from the annular portion 63B to both ends is longer on the one end 61B side than on the other end side. Therefore, the one end portion 61A can be supported by the left terminal support portion 53A so that only the one end portion 61A side protrudes from the left outer surface 60A. Similarly, the one end portion 61B can be supported by the right terminal support portion 53B so that only the one end portion 61B side protrudes from the right outer surface 60B.

  Next, with the terminal plates 52A and 52B supported by the terminal support 53 as shown in FIGS. 29 and 30, the conductor 5 is wound around the bobbin 6 using an automatic winding machine (not shown). The coil body 2 is manufactured by turning (conductive wire winding step S120). In the conducting wire winding step S120, the bobbin 6 to which the temporary fixing jig is attached is fixed to the fixing jig of the automatic winding machine, and the conducting wire 5 is wound around the body portion 8 of the bobbin 6. At this time, the bobbin 6 rotates together with the fixing jig. In this conducting wire winding step S120, the winding of the conducting wire 5 around the trunk portion 8 is automatically performed by an automatic winding machine. When the winding of the conducting wire 5 around the trunk portion 8 is completed, the bobbin 6 with the temporary fixing jig attached is removed from the fixing jig of the automatic winding machine.

  And the front-end | tip part 5A of the conducting wire 5 wound around the bobbin 6 is entangled with the one end part 61A side of the terminal board 52A, the rear end part 5B of the conducting wire 5 is respectively connected with the one end part 61B side of the terminal board 52B, and conducting wire 5 and the terminal plates 52A and 52B are connected (conductor connection step S130). In this conductive wire connecting step S130, dip soldering is performed on the binding portion, and the front end portion 5A and the rear end portion 5B of the conductive wire 5 are securely fixed to the terminal plates 52A and 52B.

  As described above, the terminal plates 52A and 52B protrude from the left outer surface 60A and the right outer surface 60B only at the one end portions 61A and 61B side. Thus, by projecting only the one end portions 61A and 61B side of the terminal plates 52A and 52B from the left outer surface 60A and the right outer surface 60B, both ends of the terminal plates 52A and 52B are left outer surface 60A and right outer surface 60B. Compared with the case where the lead wire 5 protrudes from the terminal plate 52A, the end portion 5B of the conducting wire 5 and the rear end portion 5B can be easily entangled with the terminal plates 52A and 52B.

  That is, when the other end portion is projected in addition to the one end portions 61A and 61B of the terminal plates 52A and 52B, the conductive wire 5 is connected to the other end portion when the conductive wire 5 is entangled with the one end portions 61A and 61B. It is necessary to avoid the other end so as not to get entangled. On the other hand, it is not necessary to project only the one end portions 61A and 61B.

  Next, the terminal plates 52A and 52B are moved to the fitting portion 54 side, and the annular portions 63A and 63B of the terminal plates 52A and 52B are caused to protrude from the fitting portion 54 by a predetermined amount as shown in FIGS. (Projection step S140). A slit 53SA is formed on the left outer surface 60A, which is the left side surface of the left terminal support portion 53A. The slit 53SA is formed from the opening on the left outer side surface 60A of the support hole 59A to the rear end surface of the front collar portion 9A, and the support hole 59A and the rear end surface of the front collar portion 9A communicate with each other via the slit 53SA. is doing. Also, a slit 53SB similar to the slit 53SA is formed on the right outer surface 60B, which is the right side surface of the right terminal support portion 53B, and the support hole 59B and the rear end surface of the front collar portion 9A communicate with each other via the slit 53SB. ing. Following the above-described projecting step S140, the conductive wire 5 connected to the terminal plate 52A is drawn out to the rear end surface of the front flange portion 9A through the slit 53SA, and the conductive wire 5 connected to the terminal plate 52B is similarly applied. Then, it is pulled out to the rear end surface of the front collar portion 9A through the slit 10SB. Then, the exterior tape 7 is wound by an automatic machine so as to cover the entire outer peripheral surface of the conducting wire 5 wound around the trunk portion 8.

  The coil body 2 shown in FIGS. 31 and 32 is completed through the above steps. In addition, each process, such as terminal board insertion process S110, conducting wire winding process S120, conducting wire connection process S130, protrusion process S140, may be performed automatically by an automatic machine, or may be performed manually.

  Then, as shown in FIG. 22, the bobbin 6 (coil body 2) is accommodated in the frame 4 in the direction of the arrow and fixed to the frame 4 (fixing step S150). In the fixing step S150, the frame 4 is fixed to the bobbin 6 by an automatic machine. These fixations may be performed manually.

  In parallel with or before or after the above-described steps (steps S110 to S150), as shown in FIG. 33, the lead wires 14A and 14B are supported on the fixing plate 51 (lead wire support step). The lead wires 14A and 14B are in a state in which the resin coating on the distal end side is removed in advance so that the conductive wire portions 15A and 15B are exposed at the distal ends.

  The lead wires 14A and 14B are inserted into the lead wire holding holes 68A and 68B from the openings 73A and 73B behind the lead wire holding holes 68A and 68B, with the conductive wire portions 15A and 15B facing in the fitting direction (rear). Let The covering portions 74A and 74B of the lead wires 14A and 14B are formed to be slightly thicker than the diameters of the lead wire holding holes 68A and 68B. In addition, split grooves 70A and 70B are formed in the lead wire holding holes 68A and 68B. Therefore, the lead wires 14A and 14B are supported in a state where the holding force is received in the lead wire holding holes 68A and 68B.

  That is, the lead wires 14 </ b> A and 14 </ b> B are held by the fixed plate 51 in a state where it is difficult to move in the front-rear direction. In the lead wires 14A and 14B, the lengths of the conductor portions 15A and 15B and the insertion amounts into the lead wire holding holes 68A and 68B are defined so that the conductor portions 15A and 15B face the recesses 66A and 66B.

  Subsequently, as shown in FIGS. 34 to 36, the fixing plate 51 is attached to the coil body 2 (fixing plate attachment step S160). FIG. 34 is a perspective view of the fixing plate 51 and the coil body 2 in a state before the fixing plate 51 is attached to the coil body 2. FIG. 35 is a perspective view showing a state in the middle of fitting the fixing plate 51 to the fitting portion 54. 36 is a perspective view showing a state in which the fixing plate 51 has been attached to the coil body 2, and the lower part (B) is a view of an arrow B portion shown in the upper part (A) from the rear. It is a figure which shows a schematic structure.

  As shown in FIG. 34, the fixing plate 51 is inserted into the fitting portion 54 from the upper front side of the fitting portion 54 with the side on which the guide receiving portion 65 is provided facing rearward. Further, as shown in FIG. 35, the fixing plate 51 is fitted into the fitting portion 54 so that the bridge portion 59 is fitted into the gap 65C (see FIGS. 24 and 33) of the guide receiving portion 65. The fixed plate 51 is formed in the fitting portion 54 so that the lead wires 14A and 15B of the lead wires 14A and 14B supported by the fixed plate 51 are inserted into the annular portions 63A and 63B of the terminal plates 52A and 52B. It is inserted in. When the fixing plate 51 is inserted into the fitting portion 54, the fixing plate left outer surface 60A and the fixing plate right outer surface 60B are guided in the left-right direction by the left inner surface 57A and the right inner surface 57B.

  By the way, the predetermined protruding amount of the terminal plate 52A in the above-described protruding step S120 is such that when the fixing plate 51 is fitted into the fitting portion 54, the conducting wire portion 15A is connected to the inner peripheral side (the annular portion 63A and the annular portion 63A). The projecting amount is set such that the annular portion 63A can abut against the wall portion 67A of the fixing plate 51. Similarly, when the fixing plate 51 is fitted into the fitting portion 54, the terminal plate 52B is arranged so that the conductive wire portion 15B is located on the inner peripheral side of the annular portion 63B (between the annular portion 63B and the right inner side surface 57B). The protruding amount is set such that the annular portion 63B can pass through and can come into contact with the wall portion 67B of the fixed plate 51.

  The terminal plate 52A and the terminal plate 52B are respectively supported in the support hole 59A and the support hole 59B while being inclined upward from the rear to the front. Accordingly, the opening 72A of the annular part 63A of the terminal plate 52A and the opening 72B of the annular part 63B of the terminal plate 52B are openings directed obliquely upward and forward, respectively.
