ヒュージング用端子及び電動機Fusing terminal and electric motor
　本発明は、ヒュージング用端子及び電動機に関し、特に、電動機の固定子のコイルを形成するワイヤの端末にヒュージングにより電気的に接続されるヒュージング用端子及びこのヒュージング用端子を備えた電動機に関する。 The present invention relates to a fusing terminal and an electric motor, and in particular, a fusing terminal electrically connected by fusing to a terminal of a wire forming a coil of a stator of the electric motor, and an electric motor including the fusing terminal.

　電動機などにおけるワイヤの端末処理方法として、ワイヤ及び端子に設けられワイヤを保持する保持部に電流を流し、その際の熱によりワイヤの絶縁被膜を破壊して、端子とワイヤとを電気的に接続するヒュージングという方法が知られている。 As a terminal treatment method of a wire in a motor or the like, a current is applied to a holding portion provided on the wire and the terminal to hold the wire, and the heat at that time destroys the insulating coating of the wire, thereby electrically connecting the terminal and the wire. A method called fusing is known.
　ヒュージング用端子では、ヒュージング時の熱により、ヒュージングが施されたワイヤの強度低下が発生する。そのため、特許文献１では、ヒュージング用端子に第１保持部と第２保持部とを設けた構成が開示されている。具体的には、第１保持部と第２保持部とによりワイヤの端末を挟み込んで保持した後、第１保持部のワイヤをヒュージングしてヒュージング用端子とワイヤとを電気的に接続することが提案されている。 端子 In the fusing terminal, the heat generated during fusing causes a reduction in the strength of the fused wire. Therefore, Patent Literature 1 discloses a configuration in which a fusing terminal is provided with a first holding unit and a second holding unit. Specifically, after the terminal of the wire is sandwiched and held by the first holding unit and the second holding unit, the wire of the first holding unit is fused to electrically connect the fusing terminal and the wire. It has been proposed.

　特許文献１の構成の場合、第１保持部と第２保持部との間に隙間があり、この隙間においてワイヤがむき出しになっている。そのため、電動機の固定子をモールド成形する際に樹脂がこの隙間に流入すると、第１保持部と第２保持部との間のワイヤに樹脂の外力が作用し、ワイヤが断線しやすいという問題点がある。 場合 In the configuration of Patent Document 1, there is a gap between the first holding section and the second holding section, and the wire is exposed in this gap. Therefore, when the resin flows into this gap when the stator of the electric motor is molded, external force of the resin acts on the wire between the first holding portion and the second holding portion, and the wire is easily broken. There is.

　本発明に係るヒュージング用端子によれば、ヒュージング部と本体との間のワイヤの一部が保護板の第３部分に沿い、他の部分が保持部で保持されている。このため、ヒュージングによりヒュージング部のワイヤの強度が低下していても、ヒュージング部と本体との間のワイヤの断線を抑制することができる。 According to the fusing terminal of the present invention, a part of the wire between the fusing part and the main body is along the third part of the protection plate, and the other part is held by the holding part.

　本体１０は、例えば、長尺形状である。本体１０は、長手方向の一端側が固定子１００のベース１００ｂの差込部９０に差し込まれる差込端１０ａになっており、他端側が基板１０１に接続される領域になっている。なお、本体１０は、固定子１００と基板１０１とを接続することができる形状であればよく長尺形状に限られないが、以下では説明の便宜上、長尺形状の場合について説明する。 The main body 10 has, for example, a long shape. One end of the main body 10 in the longitudinal direction is an insertion end 10 a to be inserted into the insertion portion 90 of the base 100 b of the stator 100, and the other end is an area connected to the substrate 101. The main body 10 is not limited to a long shape as long as the main body 10 can connect the stator 100 and the substrate 101, but a case of a long shape will be described below for convenience of description.
　保護板１３は、本体１０の長手方向の縁部１０ｂから、本体１０の長手方向の縁部１０ｂに垂直な方向に延びている。保護板１３は、例えば、本体１０の長手方向の縁部１０ｂに垂直な方向が長手方向となる長尺形状である。保護板１３についても、本体１０から延びる形状であればよく長尺形状に限られないが、以下では説明の便宜上、長尺形状の場合について説明する。 The protection plate 13 extends from the longitudinal edge 10b of the main body 10 in a direction perpendicular to the longitudinal edge 10b of the main body 10. The protection plate 13 has, for example, an elongated shape in which the direction perpendicular to the longitudinal edge 10b of the main body 10 is the longitudinal direction. The protection plate 13 is not limited to the elongated shape as long as it extends from the main body 10, but the following description will be made on the case of the elongated shape for convenience of explanation.
　保護板１３は、短手方向の寸法が長手方向にわたって同一な形状である。保護板１３は、保護板１３の長手方向に沿って、第１部分１３ａ、第３部分１３ｃ、及び、第２部分１３ｂを有する。第１部分１３ａと対向してヒュージング部１１が設けられており、第２部分１３ｂと対向して保持部１２が設けられている。第３部分１３ｃは、第１部分１３ａと第２部分１３ｂとの間に延在し、第１部分１３ａと第２部分１３ｂとを繋いでいる。 The protection plate 13 has the same dimension in the short direction over the long direction. The protection plate 13 has a first portion 13a, a third portion 13c, and a second portion 13b along the longitudinal direction of the protection plate 13. The fusing portion 11 is provided to face the first portion 13a, and the holding portion 12 is provided to face the second portion 13b. The third portion 13c extends between the first portion 13a and the second portion 13b, and connects the first portion 13a and the second portion 13b.
　保持部１２は、保護板１３の第２部分１３ｂの一面上に設けられている。保持部１２は、保護板１３の第２部分１３ｂとの間でコイル７０から本体１０に沿って延びるワイヤ８０を挟み、保持している。保持部１２は、保護板１３の長手方向の縁部に繋がっている。 The holding part 12 is provided on one surface of the second part 13 b of the protection plate 13. The holding portion 12 holds a wire 80 extending from the coil 70 along the main body 10 between the holding portion 12 and the second portion 13b of the protection plate 13. The holding portion 12 is connected to a longitudinal edge of the protection plate 13.
　ヒュージング部１１は、保護板１３の第１部分１３ａの一面上に設けられている。ヒュージング部１１は、保護板１３の第１部分１３ａとの間でワイヤ８０の端末８０ａを挟んでいる。ワイヤ８０の端末８０ａは、コイル７０から延びたワイヤ８０の遠位端である。ヒュージング部１１は、保護板１３の長手方向の縁部に繋がっている。保持部１２とヒュージング部１１とは、本体１０の長手方向の縁部１０ｂと垂直な方向に並んでいる。本体１０とヒュージング部１１との間に保持部１２が位置している。保持部１２とヒュージング部１１とは、なるべく近い位置に配置されている。 The fusing portion 11 is provided on one surface of the first portion 13a of the protection plate 13. The fusing unit 11 sandwiches the terminal 80 a of the wire 80 between the fusing unit 11 and the first portion 13 a of the protection plate 13. The terminal 80a of the wire 80 is the distal end of the wire 80 extending from the coil 70. The fusing portion 11 is connected to the edge of the protection plate 13 in the longitudinal direction. The holding portion 12 and the fusing portion 11 are arranged in a direction perpendicular to the longitudinal edge 10 b of the main body 10. The holding unit 12 is located between the main body 10 and the fusing unit 11. The holding unit 12 and the fusing unit 11 are arranged as close as possible.
　ヒュージング部１１には、保護板１３の第１部分１３ａとの間に挟まれたワイヤ８０の端末８０ａがヒュージングにより固定され、電気的に接続されている。ヒュージングでは、ヒュージング部１１に流れる電流によりワイヤ８０の絶縁被覆を溶かし、ワイヤ８０を被覆から露出させる。更に電流を流し、ワイヤ８０をヒュージング部１１と保護板１３との間で圧着して、ワイヤ８０とヒュージング用端子１とを機械的且つ電気的に接続している。 The terminal 80a of the wire 80 sandwiched between the fusing portion 11 and the first portion 13a of the protection plate 13 is fixed by fusing and is electrically connected. In the fusing, the electric current flowing through the fusing portion 11 melts the insulating coating of the wire 80 to expose the wire 80 from the coating. Further, a current is applied, and the wire 80 is crimped between the fusing portion 11 and the protection plate 13 to mechanically and electrically connect the wire 80 and the fusing terminal 1.
　保持部１２が設けられる第２部分１３ｂとヒュージング部１１が設けられる第１部分１３ａとの間には、保護板１３の第３部分１３ｃが延在している。第２部分１３ｂと第１部分１３ａとの間のワイヤ８０は、第３部分１３ｃに沿って延びている。 第 The third portion 13c of the protection plate 13 extends between the second portion 13b where the holding portion 12 is provided and the first portion 13a where the fusing portion 11 is provided. The wire 80 between the second portion 13b and the first portion 13a extends along the third portion 13c.
　固定子鉄心１００ａのコイル７０から延びるワイヤ８０は、本体１０側から保護板１３の第２部分１３ｂに設けられた保持部１２を通り、保護板１３の第３部分１３ｃに沿いながら保護板１３の第１部分１３ａに設けられたヒュージング部１１に至っている。ヒュージング部１１では、ワイヤ８０の端末８０ａがヒュージングにより固定され、保持部１２では、ワイヤ８０の端末８０ａとコイル７０との間のワイヤ８０が、ヒュージングが施されることなく保持される。 The wire 80 extending from the coil 70 of the stator core 100a passes through the holding portion 12 provided on the second portion 13b of the protection plate 13 from the main body 10 side, and extends along the third portion 13c of the protection plate 13 to form the protection plate 13 It reaches the fusing part 11 provided in the first part 13a. In the fusing unit 11, the terminal 80a of the wire 80 is fixed by fusing, and in the holding unit 12, the wire 80 between the terminal 80a of the wire 80 and the coil 70 is held without being subjected to fusing. .
　ヒュージング部１１のワイヤ８０の端末８０ａの強度は、ヒュージングにより低下しているが、ヒュージングが施されない保持部１２により保持されるワイヤ８０には強度低下がない。ワイヤ８０が保持部１２で保持されることで、ヒュージング部１１と本体１０との間のワイヤ８０の断線が抑制される。 (4) Although the strength of the terminal 80a of the wire 80 of the fusing unit 11 is reduced by fusing, the strength of the wire 80 held by the holding unit 12 not subjected to fusing does not decrease. Since the wire 80 is held by the holding portion 12, disconnection of the wire 80 between the fusing portion 11 and the main body 10 is suppressed.
　次に、ヒュージング用端子１と固定子鉄心１００ａのコイル７０との接続方法について説明する。まず、ヒュージング部１１及び保持部１２が形成される前にヒュージング用端子１の本体１０の差込端１０ａを、固定子鉄心１００ａのベース１００ｂの差込部９０に差し込む。このとき、ヒュージング部１１及び保持部１２となる部分は、保護板１３の長手方向の縁部から保護板１３の長手方向の縁部に垂直な方向に延びている。 Next, a method of connecting the fusing terminal 1 and the coil 70 of the stator core 100a will be described. First, before the fusing portion 11 and the holding portion 12 are formed, the insertion end 10a of the main body 10 of the fusing terminal 1 is inserted into the insertion portion 90 of the base 100b of the stator core 100a. At this time, the portions serving as the fusing portion 11 and the holding portion 12 extend in a direction perpendicular to the longitudinal edge of the protective plate 13 from the longitudinal edge of the protective plate 13.
　そして、固定子鉄心１００ａに形成されたコイル７０のワイヤ８０をヒュージング用端子１の本体１０から保護板１３に沿うように配置する。ワイヤ８０は、本体１０の長手方向の縁部１０ｂに垂直な方向に延びる保護板１３に沿って延びる。 Then, the wire 80 of the coil 70 formed on the stator core 100 a is arranged along the protection plate 13 from the main body 10 of the fusing terminal 1. The wire 80 extends along a protective plate 13 extending in a direction perpendicular to the longitudinal edge 10b of the main body 10.
　そして、ヒュージング部１１となる保護板１３に連なる部材を、保護板１３の長手方向の縁部に垂直な方向に折り返す。ヒュージング部１１は、保護板１３の第１部分１３ａに接し、保護板１３の第１部分１３ａとの間にワイヤ８０の端末８０ａを挟む。また、保持部１２となる保護板１３に連なる部材を、保護板１３の長手方向に垂直な方向に折り返す。保持部１２は、保護板１３の第２部分１３ｂに接し、保護板１３の第２部分１３ｂとの間にコイル７０側のワイヤ８０を挟む。 {Circle around (1)} The member connected to the protection plate 13 serving as the fusing portion 11 is folded back in a direction perpendicular to the longitudinal edge of the protection plate 13. The fusing portion 11 is in contact with the first portion 13a of the protection plate 13 and sandwiches the terminal 80a of the wire 80 between the fusing portion 11 and the first portion 13a of the protection plate 13. Further, a member connected to the protection plate 13 serving as the holding portion 12 is folded back in a direction perpendicular to the longitudinal direction of the protection plate 13. The holding portion 12 is in contact with the second portion 13b of the protection plate 13 and sandwiches the wire 80 on the coil 70 side with the second portion 13b of the protection plate 13.
　ここで、保持部１２とヒュージング部１１とは、なるべく近い位置に設けてあることが望ましい。保持部１２及びヒュージング部１１となる部分は、保持部１２及びヒュージング部１１となる部分を折り曲げ加工することが可能な程度の距離が間に確保されていればよい。また、ヒュージング部１１と保持部１２とは、保護板１３に連なる部材を同時に折り曲げ加工することにより形成すればよい。これにより、加工工程の増加を抑制できる。 Here, it is desirable that the holding unit 12 and the fusing unit 11 are provided as close as possible. It is only necessary that a distance between the holding portion 12 and the fusing portion 11 is secured so that the holding portion 12 and the fusing portion 11 can be bent. Further, the fusing portion 11 and the holding portion 12 may be formed by simultaneously bending members connected to the protection plate 13. Thereby, an increase in the number of processing steps can be suppressed.
　そして、ヒュージング部１１にヒュージングを施し、ワイヤ８０の端末８０ａをヒュージング部１１及び保護板１３に電気的に接続する。ワイヤ８０の端末８０ａの余剰な部分は、ヒュージング部１１の保持部１２とは反対の位置において切断する。 Then, the fusing unit 11 is subjected to fusing, and the terminal 80 a of the wire 80 is electrically connected to the fusing unit 11 and the protection plate 13. An excess portion of the terminal 80 a of the wire 80 is cut at a position opposite to the holding unit 12 of the fusing unit 11.
　これにより、ヒュージング用端子１とコイル７０とが、ワイヤ８０の端末８０ａにおいてヒュージング部１１と保護板１３の第１部分１３ａとの間で電気的に接続される。また、ヒュージング部１１とコイル７０との間のワイヤ８０が、保護板１３の第３部分１３ｃに沿いながら保持部１２に至り、保持部１２と保護板１３の第２部分１３ｂとに挟まれ保持される。 Accordingly, the fusing terminal 1 and the coil 70 are electrically connected between the fusing portion 11 and the first portion 13a of the protection plate 13 at the terminal 80a of the wire 80. Further, the wire 80 between the fusing portion 11 and the coil 70 reaches the holding portion 12 along the third portion 13c of the protection plate 13, and is sandwiched between the holding portion 12 and the second portion 13b of the protection plate 13. Will be retained.
　保持部１２及びヒュージング部１１は、保護板１３の長手方向の縁部に垂直な方向に折り返されており、ワイヤ８０が保護板１３の長手方向の縁部に沿って水平に保持されている。そのため、ワイヤ８０の切断面が、ヒュージング用端子１が固定子鉄心１００ａのベース１００ｂの差込部９０に差し込まれる差込方向と同じになり、ワイヤ８０の端末８０ａの余剰な部分の切断が容易になる。 The holding portion 12 and the fusing portion 11 are folded back in a direction perpendicular to the longitudinal edge of the protective plate 13, and the wire 80 is horizontally held along the longitudinal edge of the protective plate 13. . Therefore, the cut surface of the wire 80 becomes the same as the insertion direction in which the fusing terminal 1 is inserted into the insertion portion 90 of the base 100b of the stator core 100a. It will be easier.
　図５は、本発明の実施の形態１に係るヒュージング用端子１を用いた電動機２００の内部構成図である。図１～図５を用いて電動機２００の製造方法について説明する。 FIG. 5 is an internal configuration diagram of the electric motor 200 using the fusing terminal 1 according to Embodiment 1 of the present invention. A method of manufacturing the electric motor 200 will be described with reference to FIGS.
　まず、複数の固定子鉄心１００ａを円環状に組み合わせ、固定子１００を形成する。複数の固定子鉄心１００ａには、ヒュージング用端子１が差し込まれている。固定子１００のヒュージング用端子１が差し込まれた面には、基板１０１を配置する。それぞれの固定子鉄心１００ａのコイル７０は、ワイヤ８０の端末８０ａにおいてヒュージング用端子１に接続されている。 First, the stator 100 is formed by combining a plurality of stator cores 100a in an annular shape. The fusing terminals 1 are inserted into the plurality of stator cores 100a. A board 101 is arranged on the surface of the stator 100 into which the fusing terminals 1 are inserted. The coil 70 of each stator core 100a is connected to the fusing terminal 1 at the terminal 80a of the wire 80.
　次に、ヒュージング用端子１を介し、固定子鉄心１００ａのコイル７０と、基板１０１とを接続する。固定子１００と、ヒュージング用端子１と、基板１０１とは、モールド金型に設置され、モールド金型の内部にモールド樹脂が供給される。モールド樹脂は、モールド金型と固定子１００との隙間、及び、固定子１００と基板１０１との隙間などに流入する。 Next, the coil 70 of the stator core 100a and the board 101 are connected via the fusing terminal 1. The stator 100, the fusing terminal 1, and the substrate 101 are installed in a mold, and a mold resin is supplied into the mold. The mold resin flows into a gap between the mold and the stator 100, a gap between the stator 100 and the substrate 101, and the like.
　このとき、モールド樹脂は、ヒュージング用端子１に設けられたヒュージング部１１と保持部１２との間にも流入する。ヒュージング部１１と保持部１２との間には、ワイヤ８０が延びているが、ヒュージング部１１と保持部１２との間のワイヤ８０は、保護板１３の第３部分１３ｃに沿って延びている。そのため、モールド樹脂の流れによる外力が保護板１３に作用することとなり、ヒュージング部１１と保持部１２との間のワイヤ８０への外力の作用が抑制される。 At this time, the mold resin also flows between the fusing portion 11 provided on the fusing terminal 1 and the holding portion 12. The wire 80 extends between the fusing portion 11 and the holding portion 12, but the wire 80 between the fusing portion 11 and the holding portion 12 extends along the third portion 13c of the protection plate 13. ing. Therefore, an external force due to the flow of the mold resin acts on the protection plate 13, and the effect of the external force on the wire 80 between the fusing portion 11 and the holding portion 12 is suppressed.
　その後、モールド金型に供給したモールド樹脂を硬化させることで、図５に示す、固定子１００、基板１０１及びその他構成部品が一体成形された電動機２００が得られる。 (5) Thereafter, by curing the mold resin supplied to the mold, an electric motor 200 in which the stator 100, the substrate 101, and other components are integrally formed as shown in FIG. 5 is obtained.
　このように、ヒュージング用端子１においては、ヒュージング部１１と保持部１２との間のワイヤ８０が保護板１３の第３部分１３ｃに沿って延びており、ヒュージング部１１及び保持部１２との間でむき出しになっていない。保護板がない場合には、保持部とヒュージング部との間のワイヤがむき出しになり、モールド樹脂の流れによる外力でワイヤが断線し易い。ヒュージング部１１と保持部１２との間のワイヤ８０を保護板１３の第３部分１３ｃに沿わせることで、ヒュージング部１１と保持部１２との隙間に流入したモールド樹脂による外力が保護板１３に作用する。これにより、ワイヤ８０に作用するモールド樹脂の外力が低減され、モールド成形時のワイヤ８０の断線を抑制できる。 Thus, in the fusing terminal 1, the wire 80 between the fusing part 11 and the holding part 12 extends along the third part 13 c of the protection plate 13, and the fusing part 11 and the holding part 12 Not exposed between. If there is no protection plate, the wire between the holding portion and the fusing portion is exposed, and the wire is easily broken by an external force due to the flow of the mold resin. By arranging the wire 80 between the fusing portion 11 and the holding portion 12 along the third portion 13c of the protection plate 13, the external force due to the mold resin flowing into the gap between the fusing portion 11 and the holding portion 12 is reduced. Acts on 13. Thereby, the external force of the mold resin acting on the wire 80 is reduced, and disconnection of the wire 80 during molding can be suppressed.
　以上説明した、本実施の形態に係るヒュージング用端子１によれば、保護板１３の第１部分１３ａにヒュージング部１１を設け、保護板１３の第２部分１３ｂに保持部１２を設け、第１部分１３ａと第２部分１３ｂとの間に第３部分１３ｃが延在している。ヒュージング部１１でヒュージングにより端末８０ａが固定されたワイヤ８０は、保護板１３の第３部分１３ｃに沿いながら保持部１２に至り保持される。これにより、ヒュージングによりヒュージング部１１に固定されるワイヤ８０の端末８０ａの強度が低下していても、本体側のワイヤ８０、つまり、ワイヤ８０のコイル７０側が保持部１２で保持され、ワイヤ８０の断線が抑制される。 According to the fusing terminal 1 according to the present embodiment described above, the fusing portion 11 is provided on the first portion 13a of the protection plate 13, and the holding portion 12 is provided on the second portion 13b of the protection plate 13. A third portion 13c extends between the first portion 13a and the second portion 13b. The wire 80 to which the terminal 80 a is fixed by fusing in the fusing unit 11 reaches the holding unit 12 and is held along the third portion 13 c of the protection plate 13. Thereby, even if the strength of the terminal 80a of the wire 80 fixed to the fusing portion 11 by fusing is reduced, the wire 80 on the main body side, that is, the coil 70 side of the wire 80 is held by the holding portion 12, and the wire The disconnection of 80 is suppressed.
　また、保持部１２は、保護板１３の第２部分１３ｂとの間でワイヤ８０を挟んでいる。保持部１２のワイヤ８０は、保持部１２にヒュージングされておらずヒュージングによる強度の低下がないため、保持部１２でワイヤ８０が断線することを回避することができる。 (4) The holding portion 12 sandwiches the wire 80 between the holding portion 12 and the second portion 13b of the protection plate 13. Since the wire 80 of the holding unit 12 is not fused to the holding unit 12 and the strength is not reduced by the fusing, it is possible to prevent the wire 80 from being broken in the holding unit 12.
　また、ヒュージング部１１と保持部１２とは、保護板１３の長手方向の縁部に垂直な方向に折り返されている。これによりワイヤ８０が保護板１３の長手方向に沿ってヒュージング用端子１の差込方向に垂直に延びるため、ワイヤ８０の端末８０ａの切断が容易になる。 ヒ ュ ー Fusing part 11 and holding part 12 are folded back in a direction perpendicular to the longitudinal edge of protective plate 13. Since the wire 80 extends perpendicularly to the insertion direction of the fusing terminal 1 along the longitudinal direction of the protection plate 13, the terminal 80 a of the wire 80 can be easily cut.
　また、保持部１２をヒュージング部１１の本体１０側に設けることで、ヒュージング部１１と本体１０との間のワイヤ８０が保持部１２により保持され、ワイヤ８０の端末８０ａに作用する外力を低減することができる。これにより、ヒュージング部１１でワイヤ８０の端末８０ａの強度が低下しても、ワイヤ８０が断線することを抑制することができる。 Further, by providing the holding portion 12 on the body 10 side of the fusing portion 11, the wire 80 between the fusing portion 11 and the body 10 is held by the holding portion 12, and external force acting on the terminal 80a of the wire 80 is reduced. Can be reduced. Accordingly, even if the strength of the terminal 80a of the wire 80 is reduced in the fusing unit 11, the wire 80 can be prevented from being disconnected.
　また、電動機２００において、固定子鉄心１００ａのコイル７０と基板１０１とがヒュージング用端子１を介して接続されている。ヒュージング用端子１では、コイル７０から延びるワイヤ８０の端末８０ａがヒュージング部１１に固定され、コイル７０とヒュージング部１１との間のワイヤ８０が保護板１３に沿いながら保持部１２において保持されている。これにより、ヒュージング部１１においてヒュージングで強度が低下したワイヤ８０の端末８０ａに作用する外力が抑制され、コイル７０と基板１０１との接続をより確実にすることができる。 In the electric motor 200, the coil 70 of the stator core 100a and the board 101 are connected via the fusing terminal 1. In the fusing terminal 1, the terminal 80 a of the wire 80 extending from the coil 70 is fixed to the fusing portion 11, and the wire 80 between the coil 70 and the fusing portion 11 is held by the holding portion 12 along the protection plate 13. Have been. Accordingly, the external force acting on the terminal 80a of the wire 80 whose strength has been reduced by fusing in the fusing unit 11 is suppressed, and the connection between the coil 70 and the substrate 101 can be more reliably performed.
　また、固定子鉄心１００ａと基板１０１との接続にヒュージング用端子１を用いることで、固定子１００のモールド成形時において、モールド樹脂の流れによる外力が保護板１３に作用する。これにより、ヒュージング部１１及び保持部１２の間のワイヤ８０に作用する外力が低減され、ワイヤ８０が断線することを抑制できる。 In addition, by using the fusing terminal 1 for connecting the stator core 100 a and the substrate 101, an external force due to the flow of the molding resin acts on the protection plate 13 during the molding of the stator 100.

The second holding portion 42b holds the wire 80 extending from the coil 70b between the second holding portion 42b and the fourth portion 43d of the protection plate 43.
　ヒュージング部４１は、保護板４３の第１部分４３ａとの間で、２つのコイル７０ａ、７０ｂの間の経路のワイヤ８０を挟んでいる。ヒュージング部４１で保持されたワイヤ８０には、ヒュージングが施され、ワイヤ８０が電気的に接続されている。 The fusing portion 41 sandwiches the wire 80 in the path between the two coils 70a and 70b between the fusing portion 41 and the first portion 43a of the protection plate 43. The wire 80 held by the fusing unit 41 is subjected to fusing, and the wire 80 is electrically connected.
　ヒュージング部４１から第１の保持部４２ａに至るワイヤ８０は、第１部分４３ａと第２部分４３ｂとの間に延在する第３部分４３ｃに沿って延びている。ヒュージング部４１から第２の保持部４２ｂに至るワイヤ８０は、第１部分４３ａと第４部分４３ｄとの間に延在する第５部分４３ｅに沿って延びている。 The wire 80 extending from the fusing part 41 to the first holding part 42a extends along the third part 43c extending between the first part 43a and the second part 43b. The wire 80 extending from the fusing portion 41 to the second holding portion 42b extends along a fifth portion 43e extending between the first portion 43a and the fourth portion 43d.
　コイル７０ａから延びるワイヤ８０は、保護板４３の第２部分４３ｂに設けられた第１の保持部４２ａを通り、保護板４３の第３部分４３ｃに沿いながら保護板４３の第１部分４３ａに設けられたヒュージング部４１に至っている。 The wire 80 extending from the coil 70a passes through the first holding portion 42a provided on the second portion 43b of the protection plate 43, and is provided on the first portion 43a of the protection plate 43 along the third portion 43c of the protection plate 43. To the fusing unit 41.
　ヒュージング部４１に至ったワイヤ８０は、保護板４３の第５部分４３ｅに沿いながら保護板４３の第４部分４３ｄに設けられた第２の保持部４２ｂで保持され、本体１０側に位置するコイル７０ｂに至る。 The wire 80 reaching the fusing portion 41 is held by the second holding portion 42b provided on the fourth portion 43d of the protection plate 43 along the fifth portion 43e of the protection plate 43, and is located on the main body 10 side. It reaches the coil 70b.
　このように、ヒュージング用端子４０は、保護板４３の一面側に設けられた第１の保持部４２ａ及び第２の保持部４２ｂを有する。これにより、コイル７０ａ、７０ｂを接続するワイヤ８０がヒュージング部４１においてヒュージングされる場合にも、ワイヤ８０を第１の保持部４２ａ及び第２の保持部４２ｂで保持することができる。そのため、ヒュージング部４１においてヒュージングにより強度が低下したワイヤ８０の断線を低減することができる。 As described above, the fusing terminal 40 has the first holding portion 42a and the second holding portion 42b provided on one surface side of the protection plate 43. Accordingly, even when the wire 80 connecting the coils 70a and 70b is fused in the fusing unit 41, the wire 80 can be held by the first holding unit 42a and the second holding unit 42b. Therefore, disconnection of the wire 80 whose strength has been reduced by fusing in the fusing portion 41 can be reduced.

A wire 80 fixed to the fusing portion 41 and held by the second holding portion 42b extends along the fifth portion 43e. Therefore, even if the molding resin flows in when the electric motor 200 is formed, the external force due to the molding resin acts on the protection plate 43, so that the external force to the wire 80 is reduced. Thereby, it is possible to suppress disconnection of the wire 80 between the fusing portion 41 and the first holding portion 42a and the wire 80 between the fusing portion 41 and the second holding portion 42b due to the molding resin. it can.

It is held by the second holding portion 42b. Therefore, the first holding portion 42a and the second holding portion 42b can hold the wire 80 at a portion other than the portion where the strength is reduced by fusing the wire 80. Thereby, even when the coils 70a and 70b are connected to both sides of the fusing terminal 40, the disconnection of the wire 80 whose strength has been reduced by fusing can be suppressed.
