(Constitution)
Hereinafter, a stator portion of a PM stepping motor having a claw pole structure using the present invention will be described with reference to the drawings. FIG. 1 shows two bobbins 101 and 102 and a first stator unit 200 held between the two bobbins 101 and 102. 2 is an enlarged side view of a part of FIG. Bobbins 101 and 102 have the same structure, and have a positional relationship in which the axial direction is opposite (that is, one is inverted relative to the other in the axial direction).

  Since the bobbins 101 and 102 have the same structure, the bobbin 101 will be described as a representative here. The bobbin 101 is made of resin and is formed by injection molding using resin as a raw material. The bobbin 101 has a substantially ring shape as a whole. That is, the bobbin 101 includes a cylindrical part 111 having a cylindrical structure with a short axial length, an annular part 112 rising in a radial direction from one edge part of the cylindrical part 111 in the axial direction, and an axial direction of the cylindrical part 111 The ring portion 113 that rises in the radial direction from the other edge portion is provided. A coil wire serving as a magnet wire is wound around the outer peripheral surface of the cylindrical portion 111 in a portion between the annular portions 112 and 113 to constitute a field coil 114.

  The annular part 113 is located on the first stator part 200 side, and is formed integrally with the annular part 113 on the outer edge (upper part in the drawing) of the surface of the annular part 113 facing the bobbin 102. The terminal portion 115 is disposed. Terminal pins 116 and 117 are embedded in the terminal portion 115. The terminal pins 116 and 117 are metallic and are embedded by press fitting. The terminal pins 116 and 117 may be embedded in the terminal portion 115 by insert molding at the time of injection molding. The end portions of the windings of the field coil 114 are connected to the terminal pins 116 and 117 by tangling wires.

  That is, one end of the winding of the field coil 114 is drawn out as a lead wire 120 and further entangled with the terminal pin 116, thereby being connected to the terminal pin 116 at the entangled portion 118. Further, the other end of the winding of the field coil 114 is drawn out as a lead wire 121 and further entangled with the terminal pin 117, thereby being connected to the terminal pin 117 at the entangled portion 119. The winding operation of the field coil 114 and the binding operation to the binding portions 118 and 119 are performed by an automatic operation using a mechanical winding machine.

  On the surface of the terminal portion 115 facing the bobbin 102, two convex portions that partially protrude in the axial direction are provided. In FIG. 2, one convex-shaped part 123 is visible. The convex shape portion 123 is also formed simultaneously with other portions when the bobbin 101 is injection molded. The same applies to another convex shape portion that is not visible in the figure.

  Next, the bobbin 102 having the same structure as the bobbin 101 will be briefly described. The bobbin 102 has an annular portion 132 on the side facing the bobbin 101. A terminal portion 135 similar to the terminal portion 115 is provided at a portion facing the terminal portion 115 at the upper part of the annular portion 132. Terminal pins 136 and 137 are arranged in the terminal portion 135 in an embedded state. A field coil 134 is wound around the bobbin 102, and one end of the field coil 134 is connected to a terminal pin 136 at a binding portion 138 through a lead portion (not shown). The other end of the field coil 134 is connected to the terminal pin 137 at the binding portion 139 through the lead portion 141 (see FIG. 2).

  On the side facing the terminal portion 115 of the terminal portion 135, convex-shaped portions 142 and 143 protruding in the axial direction are arranged. The convex shape portion 142 is provided at a position facing the convex shape portion that is not visible in the drawing on the terminal portion 115 side, and the convex shape portion 143 is a position facing the convex shape portion 123 on the terminal portion 115 side. Is provided.

  Next, the first stator unit 200 will be described. The first stator portion 200 has a substantially annular structure in which a circular hole 201 for accommodating the rotor is formed inside. In this example, the first stator 200 has a structure in which stator members 210 and 220 are laminated in the axial direction. The stator members 210 and 220 are manufactured by further bending a magnetic steel sheet that is a soft magnetic material.

  The stator member 210 has an annular part 211 having a flat and substantially annular shape, and a plurality of pole teeth 212 extending from an inner edge of the annular part 211 toward a space inside the bobbin 101. The pole teeth 212 are bent in the direction shown in the drawing by bending. A plurality of pole teeth 212 are arranged in a state where there is a gap between adjacent ones at intervals along the circumferential direction.

  The stator member 220 has a flat annular portion 221 having a substantially annular shape, and a plurality of pole teeth 222 extending from an inner edge of the annular portion 221 toward a space inside the bobbin 102. The pole teeth 222 are bent in the direction shown in the drawing by bending. A plurality of pole teeth 222 are arranged in a state where there is a gap between adjacent ones at intervals along the circumferential direction. Further, the pole teeth 212 and 222 have a positional relationship shifted from the axial direction. In addition, notched portions 231 for preventing interference between the terminal portions 115 and 135 and the annular portions 221 and 221 are provided on the upper portions of the annular portions 211 and 221.

  Further, as shown in FIG. 2, the dimensions of A and B are set to satisfy the relationship 2A> B. That is, the terminal portion 115 protrudes with a dimension A in the direction of the terminal portion 135 with respect to the position in the axial direction (left and right direction in FIG. 2) of the surface 101a of the bobbin 101 that contacts the first stator portion 200. . Further, the terminal portion 135 protrudes with a dimension A in the direction of the terminal portion 115 with respect to the position in the axial direction of the surface 102 a that contacts the stator portion 200 of the bobbin 102. Here, the sum 2A of these two projecting dimensions is set to be larger than the axial thickness dimension B of the first stator portion 200. According to this setting, when the surface 101a is brought into contact with the stator member 210 and the surface 102a is brought into contact with the stator member 220, the terminal portions 115 and 135 are deformed so as to be inclined in the left and right directions in the drawing.

  A state in which these three members are overlapped and joined in the axial direction with the first stator portion 200 sandwiched between the bobbin 101 and the bobbin 102 shown in FIG. 1 is shown in FIG. 4 as the stator member 400. . In the step of obtaining the stator member 400, the bobbin 101 and the bobbin 102 are coupled in the axial direction with the first stator part 200 interposed therebetween. At this time, as shown in FIG. 3, the surface 101 a contacts the stator member 210, and the surface 102 a contacts the stator member 220. Naturally, the convex shape portion 123 and the convex shape portion 143 also come into contact with each other. However, since 2A> B, the terminal portion 115 and the terminal portion 135 are separated from each other as shown in FIG. Deforms to fall in the direction). If 2A ≦ B, the terminal portions 115 and 135 are not deformed.

  Due to the deformation of the terminal portions 115 and 135, the terminal pin 117 (116) is inclined toward the field coil 114, and the terminal pin 137 (136) is inclined toward the field coil 134. As a result, the lead part 121 (120) and the lead part 141 are loosened. That is, when the field coil 114 is wound using a winding machine and the binding portion 119 is further wound, the lead portion 121 is in a state where tension is applied after the operation is completed. . The same applies to the other lead portions. Here, when the terminal portions 115 and 135 shown in FIG. 3 are deformed, the binding portion 119 is inclined to the field coil 114 side, and the binding portion 139 is inclined to the field coil 134 side. Sag occurs. The same applies to the other lead portions.

  As shown in FIG. 4, the stator member 400 is sandwiched between the second stator portion 500 and the third stator portion 600 from the front and rear in the axial direction. The stator 700 shown in FIG. 5 is obtained by sandwiching the stator member 400 between the second stator portion 500 and the third stator portion 600 from the front and rear in the axial direction.

  The second stator unit 500 and the third stator unit 600 are manufactured by further bending a magnetic steel plate that is a soft magnetic material. The second stator 500 has a cylindrical portion 501, an annular portion 502, and a plurality of pole teeth 503 extending in the axial direction from the inner edge of the annular portion 502. Here, the plurality of pole teeth 503 are positioned at specific intervals in the circumferential direction. The third stator 600 has a cylindrical portion 601, an annular portion 602, and a plurality of pole teeth 603 extending in the axial direction from the inner edge of the annular portion 602. Here, the plurality of pole teeth 503 are positioned at specific intervals in the circumferential direction.

  In the state assembled as the stator 700 shown in FIG. 5, the plurality of pole teeth 212 and the plurality of pole teeth 503 are alternately meshed with a gap, and the plurality of pole teeth 222 and the plurality of pole teeth 603 are in a positional relationship. Are in a state of being meshed alternately with a gap.

  Although not shown, the rotor is housed inside the stator 700 in a rotatable state. The rotor has a cylindrical shape that fits inside the stator 700 with a gap therebetween, and includes a permanent magnet that is magnetized on the outer periphery so that the magnetic poles are alternately reversed along the circumferential direction. The structure of the rotor is the same as the rotor of a normal claw pole structure PM type stepping motor.

(Superiority)
The winding work of the field coils 114 and 134 using the automatic winding machine and the binding work of the binding portions 118, 119, 138, and 139 are advantageous for improving the efficiency of the work. Since the tension is applied to the wire, the lead portion (for example, portions indicated by reference numerals 120, 121, and 141) may be disconnected due to subsequent vibration or the like. According to the above example, when the stator is assembled, as shown in FIG. 3, the terminal portion 115 is inclined so as to approach the field coil 114, and the terminal portion 135 is inclined so as to approach the field coil 134. For this reason, slack occurs in the lead parts 121 and 141, and the possibility of the disconnection is reduced.

  Further, the slack of the lead portions 121 and 141 is performed when the bobbin 101 and the bobbin 102 are brought close to each other in the axial direction with the stator member 200 interposed therebetween. This operation does not require a complicated operation that causes a problem in the prior art, such as connecting the bobbins in a state where the terminal portions 115 and 138 are deformed in advance or assembling from an oblique direction.

  The degree of slack in the lead portions 121 and 141 can be adjusted by setting the value A in FIG. For this reason, it is easy to adjust the amount of slack according to the thickness and material of the coil wire, and high versatility is obtained.

(Other)
By tilting the terminal part in the direction away from the field coil in advance and connecting the bobbin, the lead part to the terminal pin can be deformed by the deformation of the terminal part that occurs from the inclined state and approaches the field coil side. A structure that forms a slack is also possible. Hereinafter, an example of this case will be described. FIG. 6 shows a direction in which the terminal portion 115 of the bobbin 101 and the terminal portion 135 of the terminal portion 135 face each other before the bobbins 101 and 102 are coupled (direction in which the binding portion 119 is separated from the field coil 114). A structure in which the binding portion 139 is inclined in advance in a direction away from the field coil 134 is shown.

  In the state of FIG. 6, tension is applied to the lead portions 121 and 141. Then, when bobbins 101 and 102 are brought into contact in the axial direction with first stator portion 200 interposed therebetween, convex shape portion 123 and convex shape portion 143 come into contact with each other, and terminal portions 115 and 135 are inclined. It deforms in the direction that occurs from (see FIG. 7). Due to the movement of the terminal blocks 115 and 135, the lead portions 121 and 141 are loosened.

  In this case, since the inclined terminal pins 117 and 137 stand vertically after the assembly, the wiring work to the terminal pins 117 and 137 after that is easy. In particular, in the case of a structure in which a connector is connected to the terminal pins 117 and 137, since the terminal pins 117 and 137 stand vertically (or at an angle close to vertical), it is easy to connect the connectors.

  In the example illustrated in FIG. 6, a groove portion 125 that is a groove extending in the width direction of the terminal portion 115 is provided at the base portion of the terminal portion 115 on the first stator portion 200 side. By providing the groove portion 125, the terminal portion 115 is bent and easily falls down. Similarly to the terminal portion 115, the terminal portion 135 is provided with a groove portion 145. By providing the groove portions 125 and 145, the bent position is stabilized, and the positional accuracy of the terminal pins 117 and 137 can be maintained high. The structure provided with the grooves 125 and 145 can also be applied to the structure shown in FIG.

  A structure in which a convex shape portion is provided only on the terminal portion 115 or a structure in which a convex shape portion is provided only on the terminal portion 135 is also possible. Further, a structure in which the convex shape portions are not provided in both the terminal portions 115 and 135 is also possible. In these cases, the dimensions of each part may be set so that 2A> B is satisfied in the structure shown in FIG. Even if the convex shape portion is only on one side terminal portion or not on both side terminal portions, the same terminal as shown in FIG. The inclination of the parts 115 and 135 can be obtained.

  This motor is not limited to a stepping motor, and can be used for a motor having a similar winding structure. The positions of the grooves 125 and 145 may be on the field coil side. The aspect of the invention is not limited to the above-described individual embodiments, and includes various modifications that can be conceived by those skilled in the art, and the effects of the present invention are not limited to the above-described contents. That is, various additions, modifications, and partial deletions can be made without departing from the concept and spirit of the present invention derived from the contents defined in the claims and equivalents thereof.

  The present invention can be used for a motor.
