TECHNICAL FIELD

[0001] The present application relates to a bobbin assembly and a manufacturing method thereof. BACKGROUND

[0002] In a motor, a bobbin assembly is sometimes provided, which generally has a bobbin main body, a terminal base projecting from the bobbin main body and provided with a terminal pin, and a coil wire including a main body winding section wound around the bobbin main body, a terminal pin winding section wound around the terminal pin and constituting a winding end section, and a transition section connecting the main body winding section and the terminal pin winding section.

[0003] In the forming process of the terminal pin winding section of the above bobbin assembly, the coil wire led out from the transition section toward the terminal pin is first wound around the root of the terminal pin, and then wound toward the front end of the terminal pin, and force is applied to the end side of the coil wire to pull the end side of the coil wire.

[0004] However, in the above method, when force is applied to the end side of the coil wire, the position of the end portion of the coil wire after being pulled off is not determined, and it is easy to adversely affect the mounting of a circuit board or the like toward the terminal pin. SUMMARY

[0005] The present application has been achieved in view of the above problems, and aims to provide a bobbin assembly and a manufacturing method thereof, in which the position of the end portion of the coil wire after being pulled off is easily determined when force is applied to the end side of the coil wire to pull the end side of the coil wire.

[0006] To achieve the above object, the present application provides a bobbin assembly having a bobbin main body, a terminal base projecting from the bobbin main body and provided with a terminal pin, and a coil wire including a main body winding section wound around the bobbin main body, a terminal pin winding section wound around the terminal pin and constituting a winding end section, and a transition section connecting the main body winding section and the terminal pin winding section, wherein the terminal pin winding section includes a first section wound from the root of the terminal pin toward the front end of the terminal pin from an end portion connected to the transition section, and a second section wound from an end portion of the first section near the front end of the terminal pin toward the root of the terminal pin, and an end portion of the second section abuts against the first section and / or a portion of the second section other than the end portion from the root side of the terminal pin near the root of the terminal pin.

[0007] According to the coil bobbin assembly of the present application, the terminal pin winding section includes a first section that is wound from the root of the terminal pin toward the front end of the terminal pin from the end portion connected to the transition section, and a second section that is wound from the end portion of the first section toward the root of the terminal pin from the end portion of the first section, and the end portion is in abutment with the portion of the second section other than the end portion and / or the first section from the root side of the terminal pin near the root of the terminal pin, so that when the end portion of the coil wire is broken by applying force to the end portion of the coil wire, the position and length of the end portion of the coil wire after being broken (i.e. the end portion of the second section) can be determined by the portion of the second section other than the end portion and / or the first section, so that the end portion of the coil wire does not adversely affect the subsequent process (e.g. the process of mounting the flexible cable or the printed circuit substrate to the terminal platform), such as causing damage to the flexible cable or the printed circuit substrate due to interference with the flexible cable or the printed circuit substrate; and when the end portion of the coil wire is broken by applying force to the end portion of the coil wire, the coil wire can be easily broken by using the portion of the second section other than the end portion and / or the first section as the abutment point with the end portion of the second section; and when the end portion of the coil wire is broken by applying force to the end portion of the coil wire, unlike the case where the coil wire is wound from the root of the terminal pin to the vicinity of the front end of the terminal pin after the coil wire is drawn from the transition section toward the terminal pin, and then the end portion of the coil wire is broken by applying force to the end portion of the coil wire, particularly when the coil wire is thick and a large force needs to be applied to the end portion of the coil wire, the terminal pin is less likely to be bent or tilted, which helps to improve the yield of the coil bobbin assembly produced.

[0008] Further, in the coil bobbin assembly of the present application, preferably the second section includes a plurality of turns wound on the terminal pin in a manner arranged along the length direction of the terminal pin, and the last turn of the plurality of turns near the end portion is in abutment with the second last turn of the plurality of turns near the end portion from the root side of the terminal pin.

[0011] According to the bobbin assembly of the present application, all of the two turns adjacent to each other in the length direction of the terminal pin in the plurality of turns are formed to at least partially abut each other, so that when the end side of the coil wire is forced to be broken to pull the end side of the coil wire, the position of the end portion of the broken coil wire can be more reliably determined by the portion of the second section other than the end portion thereof, which is closer to the front end of the terminal pin, and the end portion of the coil wire can be prevented from adversely affecting the subsequent process (for example, a process of mounting a flexible cable or a printed circuit board, etc. toward the terminal table).

[0014] Further, in the bobbin assembly of the present application, it is preferable that the number of turns of the first section wound on the terminal pin be smaller than the number of turns of the second section wound on the terminal pin.

[0015] According to the bobbin assembly of the present application, the number of turns of the first section wound on the terminal pin is smaller than the number of turns of the second section wound on the terminal pin, so that the manufacturing efficiency can be improved compared to the case where the number of turns of the first section wound on the terminal pin is equal to the number of turns of the second section wound on the terminal pin.

[0016] Further, in the bobbin assembly of the present application, it is preferable that the first section include a first turn wound on the terminal pin at a position closest to the root of the terminal pin, a last turn wound on the terminal pin at a position closest to the front end of the terminal pin, and an intermediate turn connecting the first turn and the last turn and wound on the terminal pin, the intermediate turn being formed by one turn.

[0019] According to the bobbin assembly of the present application, the connecting portion of the transition section to the first section is located on the outer side of the terminal pin, so that the connecting portion of the transition section to the first section is less likely to interfere with the flexible cable or the printed circuit substrate when the flexible cable or the printed circuit substrate is mounted at the terminal pin as compared with the case where the connecting portion of the transition section to the first section is located on the inner side of the terminal pin.

[0020] Further, in the bobbin assembly of the present application, it is preferable that the terminal pin be integrally formed with the terminal base by resin.

[0021] According to the bobbin assembly of the present application, the terminal pin is integrally formed with the terminal base by resin, so that the assembly process of the bobbin assembly can be simplified.

[0022] Further, in order to achieve the above object, the present application provides a manufacturing method of a bobbin assembly having a bobbin main body, a terminal base protruding from the bobbin main body and provided with a terminal pin, and a coil wire including a main body winding section wound around the bobbin main body and constituting a winding completion section, a terminal pin winding section wound around the terminal pin, and a transition section connecting the main body winding section and the terminal pin winding section, wherein, in a forming process of the terminal pin winding section, first, a portion of the coil wire located on the opposite side of the transition section from the main body winding section is wound around the terminal pin from the root of the terminal pin toward the tip of the terminal pin to form a first section extending from the transition section to the vicinity of the tip of the terminal pin, and then the coil wire is wound around toward the root side of the terminal pin so that the end side of the coil wire abuts against the portion of the coil wire already wound around the terminal pin in the vicinity of the root of the terminal pin in this state, and the end side of the coil wire is pulled off to form a second section extending from the first section to the vicinity of the root of the terminal pin.

[0054] Further, as shown in Figure 1 the first terminal pin 221 and the second terminal pin 222 are disposed apart in the Y direction perpendicular to the X direction.

[0055] (Structure of first terminal pin winding section)

[0056] As shown in Figure 2As shown, the first terminal pin winding section 33 includes a first section 331 that is wound from the root of the first terminal pin 221 toward the front end (the end on the X1 direction side in the drawing) of the first terminal pin 221 from the end portion connected to the first transition section 32, and a second section 332 that is wound from the end portion of the first section 331 on the front end side of the first terminal pin 221 toward the root of the first terminal pin 221, with the tip end portion 332e abutting against the portion of the second section 332 other than the tip end portion 332e and / or the first section 331 on the root side of the first terminal pin 221 in the vicinity of the root of the first terminal pin 221.

[0057] Here, the number of turns of the first section 331 wound on the first terminal pin 221 is less than the number of turns of the second section 332 wound on the first terminal pin 221.

Specifically, the first section 331 includes the first turn 3311 wound on the first terminal pin 221 at the position closest to the root of the first terminal pin 221, the last turn wound on the first terminal pin 221 at the position closest to the front end of the first terminal pin 221, and the intermediate turns connecting the first turn 3311 and the last turn and wound on the first terminal pin 221, the intermediate turns being formed of one turn.

[0060] Further, as shown, Figure 2 The connecting portion of the first transition section 32 to the first section 331 is located on the outside of the first terminal pin 221 (on the Y1 direction side in the illustrated example).

[0061] (Winding process of coil wire in bobbin assembly)

[0062] When manufacturing the winding frame assembly 1, the coil wire 30 is first wound around the second terminal pin 222 from its front end side. Then, the coil wire 30 is led out toward the winding frame body 10 and wound around the outer peripheral surface of the winding frame body 10 (for example, it is wound from the end of the winding frame body 10 near the terminal block 21 in the extension direction of the axis L toward the other end away from the terminal block 21, and then returned to the end of the winding frame body 10 near the terminal block 21 in the extension direction of the axis L). Then, the coil wire 30 is led out toward the first terminal pin 221 and wound around the first terminal pin 221. Finally, force is applied to the end side of the coil wire 30 to break the coil wire 30.

[0063] Furthermore, in the process of forming the first terminal pin winding section 33, firstly, the portion of the coil wire 30 located on the opposite side of the first transition section 32 and the main winding section 31 is wound from the root of the first terminal pin 221 toward the front end of the first terminal pin 221 to form a first section 331 extending from the first transition section 32 to near the front end of the first terminal pin 221; then, the coil wire 30 is wound toward the root side of the first terminal pin 221, so that the end side of the coil wire 30 extends from near the root of the first terminal pin 221. The root side of the first terminal pin 221 abuts against the portion of the coil wire 30 that is wound around the first terminal pin 221. In this state, the end side of the coil wire 30 is pulled off (for example, by applying force to the end side of the coil wire 30 in the X1 and Y1 directions in the figure, but not limited to this, for example, by applying force to the end side of the coil wire 30 in the X1 and Y1 directions in the figure), so as to form a second segment 332 extending from the first segment 331 to the vicinity of the root of the first terminal pin 221.

[0064] (Main technical effects of this embodiment)

[0065] According to the winding frame assembly 1 of this embodiment, the first terminal pin winding section 33 includes: a first section 331, which winds from the end connected to the first transition section 32 toward the front end of the first terminal pin 221 from the root of the first terminal pin 221; and a second section 332, which winds from the end of the first section 331 near the front end of the first terminal pin 221 toward the root of the first terminal pin 221, and the end portion 332e winds from the first terminal pin 221 near the root of the first terminal pin 221. The root side of 21 abuts against the portion of the second segment 332 excluding the end portion 332e and / or the first segment 331. Therefore, when force is applied to the end side of the coil wire 30 to break it, the position and length of the end portion 332e of the broken coil wire 332 can be determined using the portion of the second segment 332 excluding the end portion 332e and / or the first segment 331, thus preventing the end portion 332e of the coil wire 330 from interfering with subsequent processes (such as flexible cables or printed circuit boards). The installation process of the substation may cause adverse effects (e.g., interference with flexible cables or printed circuit boards, resulting in damage to the flexible cables or printed circuit boards); and when force is applied to the end side of the coil wire 30 to break it, by using the portion of the second segment 332 excluding the end portion 332e and / or the first segment 331 as the point of contact with the end portion 332e of the second segment 332, the coil wire 30 can be easily broken; and when force is applied to the end side of the coil wire 30 to break it, the coil wire 30 can be easily broken. When the end of the coil 30 breaks, unlike the case where the coil 30, which is led from the first transition section 32 toward the first terminal pin 221, is wound from the root of the first terminal pin 221 to near the front end of the first terminal pin 221 and then force is applied to the end of the coil 30 to break it, especially when the coil 30 is thick and a large force needs to be applied to the end of the coil 30, the first terminal pin 221 is less likely to bend or tilt, which helps to improve the yield rate of the manufactured winding frame assembly 1.

[0066] Furthermore, according to the winding frame assembly 1 of this embodiment, the first segment 331 includes a first loop 3311 wound around the first terminal pin 221 at a position closest to the root of the first terminal pin 221. The end portion 332e of the second segment 332 abuts against the portion of the second segment 332 closest to the end portion 332e and / or the portion of the first segment 331 closest to the first loop 3311 at a position closer to the front end of the first terminal pin 221 than the first loop 3311. Therefore, when force is applied to the end side of the coil wire 30 to break the end side of the coil wire 30, the first loop 3311 in the first segment 331 can be used to restrict the movement of the end portion 332e of the second segment 332 toward the root of the first terminal pin 221, and prevent the end portion 3323 of the second segment 332 from interfering with other parts of the winding frame body 10.

[0067] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above embodiments.

[0068] For example, in the above embodiment, the first segment 331 includes a first loop 3311 wound around the first terminal pin 221 at the position closest to the root of the first terminal pin 221. The end portion 332e of the second segment 332 abuts against the portion of the second segment 332 closest to the end portion 332e and / or the portion of the first segment 331 closest to the first loop 3311 at a position closer to the front end of the first terminal pin 221 than the first loop 3311. However, it is not limited to this. The end portion 332e of the second segment 332 may also abut against the portion of the second segment 332 closest to the end portion 332e at a position closer to the root of the first terminal pin 221 than the first loop 3311.

[0069] Furthermore, in the above embodiment, the second segment 332 includes multiple turns wound around the first terminal pin 221 in a manner arranged along the length direction of the first terminal pin 221. All two adjacent turns in the length direction of the first terminal pin 221 are formed to at least partially abut each other, but it is not limited to this. Some of the two adjacent turns in the length direction of the first terminal pin 221 may also be formed not to abut each other.

[0070] Furthermore, in the above embodiment, the first segment 331 includes: a first loop 3311 wound around the first terminal pin 221 at the position closest to the root of the first terminal pin 221; a last loop wound around the first terminal pin 221 at the position closest to the front end of the first terminal pin 221; and an intermediate loop connecting the first loop 3311 and the last loop and wound around the first terminal pin 221. The intermediate loop is formed in one loop, but is not limited to this, and the intermediate loop may also be formed in multiple loops.

[0071] Furthermore, in the above embodiment, the number of turns of the first segment 331 wound on the first terminal pin 221 is less than the number of turns of the second segment 332 wound on the first terminal pin 221, but it is not limited to this. The number of turns of the first segment 331 wound on the first terminal pin 221 may also be greater than or equal to the number of turns of the second segment 332 wound on the first terminal pin 221.

[0072] Furthermore, in the above embodiments, the terminal block 21 is integrally formed with the winding frame body 10, and the first terminal pin 221 is integrally formed with the terminal block 21 by resin. However, it is not limited to this. The terminal block 21 can also be formed separately from the winding frame body 10, and the first terminal pin 221 can also be formed separately from the terminal block 21. Moreover, the materials of the winding frame body 10, the terminal block 21 and the first terminal pin 221 are not limited to resin.

[0073] Furthermore, in the above embodiment, the connection between the first transition section 32 and the first section 331 is located outside the first terminal pin 221, but it is not limited to this. The connection between the first transition section 32 and the first section 331 is located inside the first terminal pin 221 (that is, between the first terminal pin 221 and the second terminal pin 222).

[0074] It should be understood that within the scope of this invention, the various parts of the embodiments can be freely combined, or the various parts of the embodiments can be appropriately modified or omitted.
