Description

端子の接続方法Terminal connection method

　本発明は、端子の接続方法に関する。 The present invention relates to a terminal connection method.

　従来、導体と導体の外周に設けられた絶縁皮膜とを有する絶縁導体を複数本集合して形成されたリッツ線が知られている。このリッツ線によれば、導体に流れる電流の周波数が増加するにつれて電流が導体表面に集中する表皮効果による交流抵抗の増加を抑えることができる（特許文献１～３参照）。 Conventionally, a litz wire formed by aggregating a plurality of insulated conductors having a conductor and an insulating film provided on the outer periphery of the conductor is known. According to this litz wire, it is possible to suppress an increase in AC resistance due to the skin effect in which the current concentrates on the conductor surface as the frequency of the current flowing through the conductor increases (see Patent Documents 1 to 3).

　このようなリッツ線は、各導体の外周に絶縁皮膜が設けられていることから、通常の電線のように端子圧着部にて加締めを行ったとしても電気接続することができない。このため、端子のスリーブ等（圧着部）にリッツ線を挿入し、スリーブを加締めてスリーブとリッツ線とを仮固定した状態で、半田液で満たされる半田槽に浸す手法が採用されている。 Such an litz wire is provided with an insulating film on the outer periphery of each conductor, and thus cannot be electrically connected even if crimping is performed at a terminal crimping portion like a normal electric wire. For this reason, a technique is adopted in which a litz wire is inserted into a terminal sleeve or the like (crimp part), the sleeve is crimped and the sleeve and the litz wire are temporarily fixed, and immersed in a solder bath filled with a solder solution. .

　しかし、従来の端子の接続方法では、端子圧着部とリッツ線とを仮固定した状態で半田槽に浸されるため、圧着部のみならず、所定の対象（例えば端子台のボルト取付部）に電気接続される固定部についても半田槽に浸されてしまう。このため、例えば固定部が所定の対象に対しボルト締めによって電気接続される場合、ボルト締め後に固定部の半田が剥離して締め付けが弛んでしまい、接触抵抗が増加してしまう問題があった。 However, in the conventional terminal connection method, since the terminal crimping portion and the litz wire are temporarily fixed in the solder bath, not only the crimping portion but also a predetermined target (for example, a bolt mounting portion of the terminal block) The fixed part to be electrically connected is also immersed in the solder bath. For this reason, for example, when the fixing portion is electrically connected to a predetermined target by bolting, there is a problem that the solder of the fixing portion is peeled off after bolting, the tightening is loosened, and the contact resistance is increased.

　この問題に対して、固定部をマスキングすることにより、固定部に半田が付着しないようにしたとしても、この場合には、マスキング部材の加工費が掛かってしまう。 In response to this problem, even if the fixing portion is masked to prevent the solder from adhering to the fixing portion, in this case, the processing cost of the masking member is increased.

　本発明は、このような課題を解決するものであり、その目的とするところは、接触抵抗の増加を抑えると共に、加工費の削減を図ることが可能な端子の接続方法を提供することにある。 The present invention solves such problems, and an object of the present invention is to provide a terminal connection method capable of suppressing an increase in contact resistance and reducing processing costs. .

(1) A terminal connection method for performing electrical connection between an electric wire having a conductor portion formed by collecting a plurality of conductors and a terminal having a cylindrical crimp portion into which the conductor portion is inserted and arranged and crimped. There,
The terminal includes the pressure-bonding portion, and a flat plate-like fixing portion that extends in a tube longitudinal direction from the tube end portion of the pressure-bonding portion and is electrically connected to a predetermined target,
A first step of inserting and arranging the conductor portion from the fixed portion side of the crimping portion with respect to the terminal;
After the first step, the second step of immersing the terminal in the solder solution from the crimp portion side so as not to immerse the fixing portion in the solder solution while maintaining the positional relationship between the conductor portion and the crimp portion. ,
A third step of bending the fixed portion of the terminal solder-connected to the conductor portion in the second step;
A terminal connection method comprising:
(2) A litz wire having a conductor portion formed by assembling a plurality of insulated conductors having a conductor and an insulating film provided on the outer periphery of the conductor, and a cylindrical shape in which the conductor portion is inserted and arranged and crimped A terminal connection method for electrical connection with a terminal having a crimping portion of
The terminal includes the pressure-bonding portion, and a flat plate-like fixing portion that extends in a tube longitudinal direction from the tube end portion of the pressure-bonding portion and is electrically connected to a predetermined target,
A first step of inserting and arranging the conductor portion from the fixed portion side of the crimping portion with respect to the terminal;
After the first step, the second step of immersing the terminal in the solder solution from the crimp portion side so as not to immerse the fixing portion in the solder solution while maintaining the positional relationship between the conductor portion and the crimp portion. ,
A third step of bending the fixed portion of the terminal solder-connected to the conductor portion in the second step;
A terminal connection method comprising:

　上記（１）又は（２）の端子の接続方法によれば、第１工程において圧着部の固定部側から電線（リッツ線）の導体部を挿入配置し、第２工程において半田槽に浸すため、圧着部については半田液に浸されるものの、固定部については半田液に浸されることなく、端子と電線（リッツ線）との電気接続を行いつつも、固定部への半田の付着を防止することができる。このため、固定部に付着した半田が剥離する問題が発生せず、マスキング加工についても不要となる。そして、第３工程において固定部を折り曲げることから、固定部を所定の対象に電気接続する際に電線（リッツ線）が邪魔になることを防止することができる。以上より、接触抵抗の増加を抑えると共に、加工費の削減を図ることが可能な端子の接続方法を提供することができる。 According to the terminal connection method of (1) or (2) above, the conductor part of the electric wire (Litz wire) is inserted and arranged from the fixed part side of the crimping part in the first step, and immersed in the solder bath in the second step. Although the crimping part is immersed in the solder solution, the fixing part is not immersed in the solder solution, and the solder is attached to the fixing part while making electrical connection between the terminal and the electric wire (Litz wire). Can be prevented. For this reason, the problem that the solder adhering to the fixing portion is peeled off does not occur, and the masking process becomes unnecessary. And since a fixing | fixed part is bent in a 3rd process, when electrically connecting a fixing | fixed part to a predetermined | prescribed object, it can prevent that an electric wire (Litz wire) becomes obstructive. As described above, it is possible to provide a terminal connection method capable of suppressing an increase in contact resistance and reducing the processing cost.

　（３）　前記固定部は、前記圧着部の筒長手方向距離よりも大きく延在した平板部と、前記平板部を挟んで前記圧着部の反対側に設けられ前記所定の対象と接触する電気接続部とを有し、
　前記第３工程では、前記平板部の前記圧着部側が折り曲げられる上記（１）又は（２）に記載の端子の接続方法。 (3) The fixing portion is provided with a flat plate portion extending larger than a distance in the cylinder longitudinal direction of the crimping portion, and an electrical connection that is provided on the opposite side of the crimping portion across the flat plate portion and contacts the predetermined object. And
In the third step, the terminal connection method according to the above (1) or (2), wherein the crimping portion side of the flat plate portion is bent.

　上記（３）の端子の接続方法によれば、第３工程では平板部の圧着部側が折り曲げられるため、平板部を１８０°折り曲げた場合、電気接続部が圧着部よりも電線（リッツ線）先端方向に突出し易くなる。これにより、既存の電線（リッツ線）用の端子と同様の電気接続部と圧着部との位置関係となり、所定の対象への取り付けの際に取り付け難くなってしまう可能性を低減することができる。 According to the terminal connection method of (3) above, since the crimping portion side of the flat plate portion is bent in the third step, when the flat plate portion is bent 180 °, the electric connection portion is more distal than the crimp portion. It becomes easy to protrude in the direction. Thereby, it becomes the positional relationship of the electrical connection part and crimping | compression-bonding part similar to the terminal for existing electric wires (Litz wire), and it is possible to reduce the possibility of difficulty in attachment when attaching to a predetermined target. .

　本発明によれば、接触抵抗の増加を抑えると共に、加工費の削減を図ることが可能な端子の接続方法を提供することができる。 According to the present invention, it is possible to provide a terminal connection method capable of suppressing an increase in contact resistance and reducing processing costs.

　以下、本発明を実施形態に基づいて説明するが、本発明は以下の実施形態に限られるものではない。 Hereinafter, the present invention will be described based on embodiments, but the present invention is not limited to the following embodiments.

　図１は、本発明の実施形態に係る端子の接続方法に用いられる端子及びリッツ線を示す斜視図である。図１に示す端子１０は、リッツ線２０と電気接続されるものであって、概略的に圧着部１１と、固定部１２とから構成されている。 FIG. 1 is a perspective view showing terminals and litz wires used in a terminal connection method according to an embodiment of the present invention. A terminal 10 shown in FIG. 1 is electrically connected to a litz wire 20 and is generally composed of a crimping part 11 and a fixing part 12.

　圧着部１１は、筒形状の金属部材によって構成され、リッツ線２０の導体部２１が挿入配置される部位である。また、この圧着部１１は、リッツ線２０の導体部２１が挿入されると加締められ圧着されることとなる。これにより、導体部２１を有するリッツ線２０と圧着部１１を有する端子１０とは所定の位置関係で保持された仮固定状態とされる。 The crimping part 11 is comprised by the cylindrical metal member, and is a site | part by which the conductor part 21 of the litz wire 20 is inserted and arrange | positioned. Moreover, this crimping | compression-bonding part 11 will be crimped and crimped | bonded when the conductor part 21 of the litz wire 20 is inserted. Thereby, the litz wire 20 having the conductor portion 21 and the terminal 10 having the crimping portion 11 are in a temporarily fixed state held in a predetermined positional relationship.

　固定部１２は、圧着部１１の筒端部から筒長手方向に延在する平板状の金属部材であって、平板部１２ａと電気接続部１２ｂとからなる。平板部１２ａは、圧着部１１の筒長手方向距離よりも大きく延在した板材である。電気接続部１２ｂは、平板部１２ａを挟んで圧着部１１の反対側に設けられた板材である。この電気接続部１２ｂには、ボルト締め用の穴部１２ｃが形成されている。穴部１２ｃは、所定の対象と共にボルトが挿入されて締められることにより、当該所定の対象と固定され、これにより、電気接続部１２ｂと所定の対象との電気接続が行われることとなる。 The fixing part 12 is a flat metal member extending in the cylinder longitudinal direction from the cylinder end of the crimping part 11, and includes a flat plate part 12a and an electrical connection part 12b. The flat plate portion 12 a is a plate material that extends larger than the distance in the cylinder longitudinal direction of the crimping portion 11. The electrical connection portion 12b is a plate material provided on the opposite side of the crimping portion 11 with the flat plate portion 12a interposed therebetween. Bolt tightening holes 12c are formed in the electrical connection portion 12b. The hole 12c is fixed to the predetermined target by inserting a bolt together with the predetermined target and tightening, and thereby the electrical connection between the electrical connecting portion 12b and the predetermined target is performed.

　図２は、図１に示したリッツ線２０の詳細を示す断面図である。図２に示すように、リッツ線２０は、導体素線（導体）２２ａと、導体素線２２ａの外周に設けられたエナメル被覆（絶縁皮膜）２２ｂとを有する絶縁導体素線（絶縁導体）２２を複数本集合して導体部２１を形成したものである。また、本実施形態においてリッツ線２０は、導体部２１の外周に絶縁体からなる被覆部２３を備えている。 FIG. 2 is a cross-sectional view showing details of the litz wire 20 shown in FIG. As shown in FIG. 2, the litz wire 20 is an insulated conductor strand (insulated conductor) 22 having a conductor strand (conductor) 22a and an enamel coating (insulating film) 22b provided on the outer periphery of the conductor strand 22a. A conductor portion 21 is formed by assembling a plurality of wires. In the present embodiment, the litz wire 20 includes a covering portion 23 made of an insulator on the outer periphery of the conductor portion 21.

　次に、本実施形態に係る端子１０の接続方法について説明する。図３～図５は、本実施形態に係る端子の接続方法を示す工程図である。まず、作業者又は装置（以下作業者等という）は、図１及び図２に示すリッツ線２０の被覆部２３を除去する。これにより、リッツ線２０の導体部２１を露出させる。 Next, a method for connecting the terminals 10 according to the present embodiment will be described. 3 to 5 are process diagrams showing a terminal connection method according to this embodiment. First, an operator or an apparatus (hereinafter referred to as an operator or the like) removes the covering portion 23 of the litz wire 20 shown in FIGS. Thereby, the conductor part 21 of the litz wire 20 is exposed.

　次に、図３（ａ）及び図３（ｂ）に示すように、作業者等は、筒形状の圧着部１１に対して導体部２１を挿入配置する（第１工程）。この際、導体部２１は、端子１０の固定部１２側から圧着部１１に挿入される（図３（ａ））。挿入後、圧着部１１は加締められ、圧着部１１と導体部２１とは所定の位置関係で保持された仮固定状態とされる（図３（ｂ））。 Next, as shown in FIGS. 3 (a) and 3 (b), an operator or the like inserts and arranges the conductor portion 21 in the cylindrical crimp portion 11 (first step). At this time, the conductor part 21 is inserted into the crimping part 11 from the fixed part 12 side of the terminal 10 (FIG. 3A). After the insertion, the crimping part 11 is crimped, and the crimping part 11 and the conductor part 21 are in a temporarily fixed state held in a predetermined positional relationship (FIG. 3B).

　その後、図４に示すように、作業者等は、導体部２１と端子１０（圧着部１１）とを位置関係を保持したまま、端子１０の圧着部１１を半田液で満たされる半田槽に、圧着部側１１から浸す（第２工程）。この際、作業者等は、固定部１２を半田液に浸さないように圧着部１１を半田液に浸す。これにより、固定部１２には半田が付着しないこととなる。 Thereafter, as shown in FIG. 4, an operator or the like holds the conductor part 21 and the terminal 10 (crimp part 11) in a solder bath filled with the solder solution while keeping the positional relation between the conductor part 21 and the terminal 10 (crimp part 11). Immerse from the crimping part side 11 (second step). At this time, the operator or the like immerses the crimping portion 11 in the solder solution so that the fixing portion 12 is not immersed in the solder solution. As a result, solder does not adhere to the fixed portion 12.

　また、この工程において、半田液の熱によってエナメル被覆２２ｂは除去されることとなり、端子１０とリッツ線２０とが電気的に接続される。そして、半田の固化により両者は固定接続状態となる。 In this process, the enamel coating 22b is removed by the heat of the solder solution, and the terminal 10 and the litz wire 20 are electrically connected. And both of them are fixedly connected by solidification of the solder.

　次いで、図５（ａ）及び図５（ｂ）に示すように、作業者等は、固定部１２を１８０°折り曲げる（第３工程）。この際、作業者等は、固定部１２のうち平板部１２ａの圧着部１１側を折り曲げる（具体的には符号Ａ部分を折り曲げる）。ここで、平板部１２ａは圧着部１１の筒長手方向よりも長尺となっている。このため、平板部１２ａの圧着部１１側を１８０°折り曲げた場合、図５（ａ）及び図５（ｂ）に示すように、電気接続部１２ｂが圧着部１１よりもリッツ線２０の先端方向に突出する。これにより、電気接続部１２ｂの所定の対象への取り付けの際にリッツ線２０が邪魔とならないようにすることができる。 Next, as shown in FIGS. 5A and 5B, the operator or the like bends the fixing portion 12 by 180 degrees (third step). At this time, the operator or the like bends the crimping portion 11 side of the flat plate portion 12a in the fixing portion 12 (specifically, the portion A is folded). Here, the flat plate portion 12 a is longer than the longitudinal direction of the crimp portion 11. For this reason, when the crimping | compression-bonding part 11 side of the flat plate part 12a is bend | folded 180 degrees, as shown to Fig.5 (a) and FIG.5 (b), the electrical connection part 12b is the front end direction of the litz wire 20 rather than the crimping | compression-bonding part 11. Protrusively. Thereby, it is possible to prevent the litz wire 20 from interfering when the electrical connection portion 12b is attached to a predetermined target.

　その後、作業者等は、電気接続部１２ｂの穴部１２ｃ及び所定の対象の穴部にボルトを挿入して締めることにより、リッツ線２０と電気接続された端子１０を所定の対象に固定且つ電気接続する。 After that, the operator or the like fixes the terminal 10 electrically connected to the litz wire 20 to the predetermined target and electrically connects the bolt 10 into the hole 12c of the electric connection portion 12b and the predetermined target hole and tightens the bolt. Connecting.

　このようにして、第１実施形態に係る端子１０の接続方法によれば、第１工程において圧着部１１の固定部１２側からリッツ線２０の導体部２１を挿入配置し、第２工程において半田槽に浸すため、圧着部１１については半田液に浸されるものの、固定部１２については半田液に浸されることなく、端子１０とリッツ線２０との電気接続を行いつつも、固定部１２への半田の付着を防止することができる。このため、固定部１２に付着した半田が剥離する問題が発生せず、マスキング加工についても不要となる。そして、第３工程において固定部１２を折り曲げることから、固定部１２を所定の対象に電気接続する際にリッツ線２０が邪魔になることを防止することができる。以上より、接触抵抗の増加を抑えると共に、加工費の削減を図ることが可能な端子の接続方法を提供することができる。 Thus, according to the connection method of the terminal 10 according to the first embodiment, the conductor portion 21 of the litz wire 20 is inserted and arranged from the fixing portion 12 side of the crimping portion 11 in the first step, and the solder in the second step. In order to immerse in the bath, the crimping portion 11 is immersed in the solder solution, but the fixing portion 12 is not immersed in the solder solution and the terminal 10 and the litz wire 20 are electrically connected, and the fixing portion 12 is immersed. It is possible to prevent the solder from adhering to the surface. For this reason, the problem that the solder adhering to the fixing part 12 peels does not occur, and the masking process becomes unnecessary. And since the fixing | fixed part 12 is bent in a 3rd process, when electrically connecting the fixing | fixed part 12 to a predetermined object, it can prevent that the litz wire 20 becomes obstructive. As described above, it is possible to provide a terminal connection method capable of suppressing an increase in contact resistance and reducing the processing cost.

　また、第３工程では平板部１２ａの圧着部１１側が折り曲げられるため、平板部１２ａを１８０°折り曲げた場合、電気接続部１２ｂが圧着部１１よりもリッツ線２０の先端方向に突出し易くなる。これにより、電気接続部１２ｂと圧着部１１との位置関係は、既存のリッツ線用の端子と同様となり、所定の対象への取り付けの際に取り付け難くなってしまう可能性を低減することができる。 Also, in the third step, the crimping part 11 side of the flat plate part 12a is bent, so that when the flat plate part 12a is bent 180 °, the electrical connection part 12b is more likely to protrude in the tip direction of the litz wire 20 than the crimping part 11. Thereby, the positional relationship between the electrical connection portion 12b and the crimping portion 11 is the same as that of the existing litz wire terminal, and the possibility of difficulty in attachment when attaching to a predetermined target can be reduced. .

　本発明を詳細にまた特定の実施態様を参照して説明したが、本発明の精神と範囲を逸脱することなく様々な変更や修正を加えることができることは当業者にとって明らかである。 Although the present invention has been described in detail and with reference to specific embodiments, it will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit and scope of the invention.

　例えば、本実施形態に係る接続用端子１において圧着部１１は円筒状でなくともよく他の形状であってもよい。さらに、固定部１２は１８０°に折り曲げられる場合に限らず、９０°等の他の角度に折り曲げられてもよいし、可能であれば水平方向に折り曲げられてもよい。 For example, in the connection terminal 1 according to the present embodiment, the crimping portion 11 does not have to be cylindrical and may have another shape. Further, the fixing portion 12 is not limited to be bent at 180 °, but may be bent at another angle such as 90 °, or may be bent in the horizontal direction if possible.

　また、上記の如く端子１０と接続されたリッツ線２０については、非接触給電装置のコイルユニット内に使用される場合、非接触給電の方式は、電磁誘導方式であってもよいし、磁気共鳴方式であってもよい。 As for the litz wire 20 connected to the terminal 10 as described above, when used in the coil unit of the non-contact power supply device, the non-contact power supply method may be an electromagnetic induction method or magnetic resonance. It may be a method.
