Abstract

PROBLEM TO BE SOLVED: To provide a connecting terminal excellent in workability when a Litz wire is inserted.SOLUTION: A crimp part 10 includes a cylindrical body that comprises a cylindrical peripheral side wall 11, and an end of a conductor 101 is inserted thereinto. A fixing part 20 is formed integrally with one end (on the side of a second opening 11b) of the crimp part 10, and fixed to a predetermined object to establish an electric connection. Thus, the peripheral side wall 11 pertaining to the crimp part 10 is formed by being widened in a tapered shape from the second opening 11b to a first opening 11a.

Description

本発明は、接続用端子に関する。   The present invention relates to a connection terminal.

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）。このため、リッツ電線は、例えば地上側のコイルと車両に設けられたコイルとの間で非接触による電力の伝送を行う非接触電力伝送装置のコイル部分に好適に用いられる。   Conventionally, a litz wire formed by collecting 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). For this reason, a litz electric wire is used suitably for the coil part of the non-contact electric power transmission apparatus which transmits electric power by non-contact between the coil on the ground side and the coil provided in the vehicle, for example.

このようなワイヤレスでの電力伝送を行う非接触電力伝送装置としては、電磁誘導現象を利用した電磁誘導方式、電磁波を利用した電磁波送信方式、共鳴現象を利用した共鳴方式などが知られている。例えば、共鳴方式は、送信共鳴コイルに交流電力を供給し、電磁場を介して送信共鳴コイルとこれに対向配置された受信共鳴コイルとを共鳴させて電力を伝送する技術であり、数ｋＷの大電力を比較的離れた場所間で伝送することが可能となっている。   As such a non-contact power transmission device that performs wireless power transmission, an electromagnetic induction method using an electromagnetic induction phenomenon, an electromagnetic wave transmission method using an electromagnetic wave, a resonance method using a resonance phenomenon, and the like are known. For example, the resonance method is a technique for supplying AC power to a transmission resonance coil and transmitting power by resonating the transmission resonance coil with a reception resonance coil arranged opposite thereto via an electromagnetic field. Electric power can be transmitted between relatively remote locations.

リッツ線の端部には、所定の対象に固定して当該リッツ線の電気接続を行う接続用端子が接続されることになる。接続用端子は、当該端部を挿入するための圧着部を備えており、この圧着部は、例えば丸型等の筒状の周側壁を備えた筒状体で構成されている。ところで、リッツ線を圧着部に挿入する場合には、個々の素線がばらつき易い状態にあるため、端子の圧着部への挿入の際に素線がはみ出し易いという問題がある。また、リッツ線では個々の素線の素線径も細いため、このような問題が顕著となる。そのため、圧着部に挿入する際には、リッツ線の先端部を整える必要があり、挿入作業に手間がかかるという問題がある。   A connection terminal that is fixed to a predetermined target and electrically connected to the litz wire is connected to the end of the litz wire. The connection terminal includes a crimping part for inserting the end part, and the crimping part is configured by a cylindrical body having a cylindrical peripheral side wall such as a round shape. By the way, when inserting a litz wire into a crimping part, since individual strands are in a state of being easily dispersed, there is a problem that the strand is likely to protrude when the terminal is inserted into the crimping part. Moreover, since the strand diameter of each strand is thin with a litz wire, such a problem becomes remarkable. Therefore, when inserting into a crimping | compression-bonding part, it is necessary to prepare the front-end | tip part of a litz wire, and there exists a problem that insertion work takes time.

本発明はかかる事情に鑑みてなされたものであり、その目的は、圧着部への導体の挿入時の作業性に優れる接続用端子を提供する。   This invention is made | formed in view of this situation, The objective provides the terminal for a connection excellent in the workability | operativity at the time of insertion of the conductor to a crimping | compression-bonding part.

かかる課題を解決するために、本発明は、導体に対して電気接続される接続用端子であって、筒状の周側壁を備えた筒状体で構成され、導体の端部が挿入される圧着部と、圧着部と一体に形成された固定部と、を有する接続端子を提供する。ここで、周側壁は、導体の端子挿入方向における奥側位置から導体の挿入側に相当する第１開口にかけて拡幅して形成される。   In order to solve such a problem, the present invention is a connection terminal that is electrically connected to a conductor, and is constituted by a cylindrical body having a cylindrical peripheral side wall, into which an end of the conductor is inserted. Provided is a connection terminal having a crimping part and a fixing part formed integrally with the crimping part. Here, the peripheral side wall is formed to be widened from the back side position in the terminal insertion direction of the conductor to the first opening corresponding to the conductor insertion side.

ここで、本発明において、周側壁は、第１開口と反対側に位置付けられる第２開口から第１開口にかけてテーパー状に拡幅されることが好ましい。   Here, in the present invention, it is preferable that the peripheral side wall is widened in a tapered shape from the second opening positioned on the side opposite to the first opening to the first opening.

また、本発明において、周側壁は、第１開口側の一部領域のみがテーパー状に拡幅されることが好ましい。   In the present invention, it is preferable that the peripheral side wall is widened in a tapered shape only in a partial region on the first opening side.

本発明によれば、リッツ線の挿入時の作業性に優れる接続用端子を提供することができる。   ADVANTAGE OF THE INVENTION According to this invention, the terminal for a connection excellent in workability | operativity at the time of insertion of a litz wire can be provided.

（第１の実施形態）
図１は、第１の実施形態に係る接続用端子１を示す上面図である。図２は、図１に示す接続用端子１を示す説明図であり、（ａ）は接続用端子１の側面図であり、（ｂ）は接続用端子１の上面図である。本実施形態に係る接続用端子１は、リッツ線１００が電気接続されるためのものである。 (First embodiment)
FIG. 1 is a top view showing the connection terminal 1 according to the first embodiment. FIG. 2 is an explanatory view showing the connection terminal 1 shown in FIG. 1, (a) is a side view of the connection terminal 1, and (b) is a top view of the connection terminal 1. The connection terminal 1 according to the present embodiment is for electrically connecting the litz wire 100.

ここで、リッツ線１００は、複数の素線を集合させてなる導体１０１と、その周囲を覆う被覆部１０２とで構成されている。導体１０１を構成する個々の素線は、それぞれの表面がエナメルなどでコートされた絶縁導体で構成されている。このリッツ線１００の端部では、接続用端子１との接続のため、導体１０１周囲の被覆部１０２が所定の範囲にわたり除去されている。   Here, the litz wire 100 is composed of a conductor 101 formed by assembling a plurality of strands and a covering portion 102 covering the periphery thereof. Each element wire constituting the conductor 101 is constituted by an insulated conductor whose surface is coated with enamel or the like. At the end of the litz wire 100, the covering portion 102 around the conductor 101 is removed over a predetermined range for connection to the connection terminal 1.

本実施形態に係る接続用端子１は、圧着部１０と、固定部２０とで構成されている。圧着部１０と固定部２０とは一体形成されており、本実施形態では、導体１０１の挿入方向Ｘに対応して圧着部１０と固定部２０とが直線的に並ぶように配置されている。   The connection terminal 1 according to this embodiment includes a crimping portion 10 and a fixing portion 20. The crimping part 10 and the fixing part 20 are integrally formed, and in this embodiment, the crimping part 10 and the fixing part 20 are arranged so as to be linearly arranged corresponding to the insertion direction X of the conductor 101.

圧着部１０は、リッツ線１００たる導体１０１の端部が挿入されるものであり、筒状の周側壁１１を備えた筒状体で構成されている。この周側壁１１は、導体１０１が挿入される側に位置付けられる第１開口１１ａと、この第１開口１１ａと反対側、すなわち固定部２０が接続する側に位置付けられる第２開口１１ｂとを有している。周側壁１１の内部に形成される空間は、第１開口１１ａと第２開口１１ｂとを相互に連通するものである。   The crimping portion 10 is inserted with the end portion of the conductor 101 which is the litz wire 100, and is constituted by a cylindrical body provided with a cylindrical peripheral side wall 11. The peripheral side wall 11 has a first opening 11a positioned on the side where the conductor 101 is inserted, and a second opening 11b positioned on the side opposite to the first opening 11a, that is, the side to which the fixing portion 20 is connected. ing. The space formed inside the peripheral side wall 11 communicates the first opening 11a and the second opening 11b with each other.

本実施形態において、圧着部１０に係る周側壁１１は、第２開口１１ｂから第１開口１１ａにかけてテーパー状に拡幅して形成されている。また、第１開口１１ａの開口径、第２開口１１ｂの開口径、導体１０１の外径を比較すると、これらには、第１開口１１ａの開口径＞第２開口１１ｂの開口径＞導体１０１の外径となる関係が存在する。もっとも、周側壁１１は、第２開口１１ｂから第１開口１１ａにかけて拡幅すればよく、テーパー状に限らず、曲線的な広がりを有するものであってもよい。   In this embodiment, the peripheral side wall 11 which concerns on the crimping | compression-bonding part 10 is formed so that it may be taper-shaped widened from the 2nd opening 11b to the 1st opening 11a. Further, when comparing the opening diameter of the first opening 11 a, the opening diameter of the second opening 11 b, and the outer diameter of the conductor 101, these include: the opening diameter of the first opening 11 a> the opening diameter of the second opening 11 b> the conductor 101. There is a relationship that becomes the outer diameter. But the surrounding side wall 11 should just be expanded from the 2nd opening 11b to the 1st opening 11a, and may have not only a taper shape but a curvilinear expansion.

固定部２０は、圧着部１０の一方の端部（第２開口１１ｂ側）に一体で形成されるものであり、例えば先端側にボルト締め用の穴部２１が形成された板材である。この穴部２１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て電気接続が行われることとなる。   The fixing portion 20 is formed integrally with one end portion (the second opening 11b side) of the crimping portion 10, and is, for example, a plate material in which a bolt fastening hole portion 21 is formed on the tip end side. The hole 21 is fixed to the predetermined target and electrically connected by inserting a bolt together with the predetermined target and tightening.

次に、本実施形態に係る接続用端子１を用いた端子接続方法を説明する。まず、リッツ線１００の被覆部１０２を除去する。これにより、リッツ線１００の端部側における導体１０１を露出させる。   Next, a terminal connection method using the connection terminal 1 according to the present embodiment will be described. First, the covering portion 102 of the litz wire 100 is removed. Thereby, the conductor 101 on the end side of the litz wire 100 is exposed.

導体１０１と、接続用端子１とがその挿入方向に沿って直列状態となるように並べ、導体１０１を圧着部１０側へとその長手方向（挿入方向Ｘ）に移動させ、当該導体１０１を第１開口１１ａへと挿入する。   The conductor 101 and the connection terminal 1 are arranged so as to be in a serial state along the insertion direction, the conductor 101 is moved in the longitudinal direction (insertion direction X) toward the crimping portion 10 side, and the conductor 101 is Insert into one opening 11a.

そして、この状態から導体１０１をさらに挿入方向Ｘへと押し込む。これにより、導体１０１の端部が第２開口１１ｂから突出し、導体１０１が圧着部１０（周側壁１１）に完全に挿入されたことが確認される。   Then, the conductor 101 is further pushed in the insertion direction X from this state. Thereby, it is confirmed that the end portion of the conductor 101 protrudes from the second opening 11b, and the conductor 101 is completely inserted into the crimping portion 10 (the peripheral side wall 11).

次いで、作業者は、この位置関係を保持したまま、接続用端子１を半田槽に浸す。これにより、周側壁１１内に挿入された導体１０１とその周側壁１１との隙間に半田が入り込むこととなる。この際、半田によりエナメルの絶縁層が剥離されることで、圧着部１０と導体１０１との電気接続が行われ、半田の固化により両者は固定接続されることとなる。   Next, the operator immerses the connection terminal 1 in the solder bath while maintaining this positional relationship. As a result, the solder enters the gap between the conductor 101 inserted into the peripheral side wall 11 and the peripheral side wall 11. At this time, the enamel insulating layer is peeled off by the solder so that the crimping portion 10 and the conductor 101 are electrically connected, and the two are fixedly connected by the solidification of the solder.

なお、作業者は、接続用端子１を半田槽に浸すにあたり、固定部２０（特に穴部２１付近）をマスキングすることにより、当該部位に半田が付着しないようにする。これには、穴部２１付近に半田が付着のうえ固化した状態でボルト締めを行うと、後に半田が剥がれてしまった場合には、ボルト締め部における接触抵抗が高まってしまうからであり、これを防止するためである。   In addition, when an operator immerses the connection terminal 1 in the solder bath, the fixing portion 20 (particularly, near the hole portion 21) is masked so that the solder does not adhere to the portion. This is because, if the bolt is tightened in a state where the solder is attached and solidified in the vicinity of the hole portion 21, if the solder is peeled off later, the contact resistance at the bolt tightening portion is increased. It is for preventing.

このようにして、本実施形態によれば、周側壁１１をその全域にかけてテーパー形状に設定することで、第１開口１１ａの開口サイズを大きく設定することができる。そのため、導体１０１の端部において複数本の素線がばらついた状態であったとしても、圧着部１０への挿入の際に素線が第１開口１１ａからはみ出しにくくなる。そのため、導体１０１の先端部を丁寧に整えずとも、これを圧着部１０に挿入することができるので、挿入時の作業負担を低減することができる。これにより、リッツ線１００の挿入時における作業性の向上を図ることができる。   Thus, according to this embodiment, the opening size of the 1st opening 11a can be set large by setting the surrounding side wall 11 to the taper shape over the whole region. Therefore, even if a plurality of strands are scattered at the end portion of the conductor 101, the strands are difficult to protrude from the first opening 11a when inserted into the crimping portion 10. For this reason, the conductor 101 can be inserted into the crimping portion 10 without carefully preparing the tip, so that the work load during insertion can be reduced. Thereby, the workability | operativity at the time of insertion of the litz wire 100 can be aimed at.

すなわち、従来の構造では、圧着部における内部空間（導体を挿入する空間）は、導体の挿入方向にかけて断面形状が同一のままに設定されていた。また、導体の外径に対応して圧着部の開口が選択されるため、端子の圧着部への挿入の際に素線がはみ出し易いという問題がある。また、導体の外径よりも開口が大きな圧着部を選択してもよいが、内部空間の全域において断面形状が大きいままなので、導体と圧着部との間のクリアランスが大きく導体の固定性能を低下させる懸念がある。この点、本実施形態によれば、第２開口１１ｂ側へと至るに従い、内部空間の断面形状が小さくなるので、そのクリアランスも小さくなり、上述の問題を生じることはない。   That is, in the conventional structure, the internal space (the space in which the conductor is inserted) in the crimping portion is set to have the same cross-sectional shape in the conductor insertion direction. In addition, since the opening of the crimping portion is selected corresponding to the outer diameter of the conductor, there is a problem that the strands easily protrude when the terminal is inserted into the crimping portion. In addition, you may select a crimping part with a larger opening than the outer diameter of the conductor, but the cross-sectional shape remains large throughout the interior space, so the clearance between the conductor and the crimping part is large and the fixing performance of the conductor is reduced There is a concern. In this respect, according to the present embodiment, the cross-sectional shape of the internal space becomes smaller as it reaches the second opening 11b side, so that the clearance becomes smaller and the above-described problem does not occur.

また、本実施形態によれば、第１開口１１ａの開口サイズが大きくなることで、半田槽に浸してエナメルの絶縁層を剥離するときに発生する燃焼ガスや剥離カスが流動し易く、これらの排出を容易に行うことができる。これにより、半田作業後における半田浸け部分のクリーニングが容易にとなるともに、接続抵抗の低減を期待することができる。   In addition, according to the present embodiment, the opening size of the first opening 11a is increased, so that the combustion gas and peeling debris generated when the enamel insulating layer is peeled off by being immersed in the solder bath easily flow. Ejection can be performed easily. This facilitates cleaning of the solder-immersed part after the soldering operation and can be expected to reduce the connection resistance.

なお、本実施形態は上記の端子接続方法に限らず、例えば導体１０１を圧着部１０に挿入した後に、この圧着部１０を加締めることにより、圧着部１０と導体１０１とを固定のうえ電気接続を行うようにしてもよい。   The present embodiment is not limited to the above terminal connection method. For example, after the conductor 101 is inserted into the crimping part 10, the crimping part 10 is crimped to fix the crimping part 10 and the conductor 101 to be electrically connected. May be performed.

（第２の実施形態）
図３は、第２の実施形態に係る接続用端子１を示す説明図であり、（ａ）は接続用端子１の側面図であり、（ｂ）は接続用端子１の上面図である。第２実施形態に係る接続用端子１が、第１実施形態のそれと相違する点は、圧着部１０を構成する周側壁１１の形態である。以下、第１の実施形態に係る接続用端子１との相違点を中心に説明を行う。 (Second Embodiment)
3A and 3B are explanatory views showing the connection terminal 1 according to the second embodiment, wherein FIG. 3A is a side view of the connection terminal 1 and FIG. 3B is a top view of the connection terminal 1. The connection terminal 1 according to the second embodiment is different from that of the first embodiment in the form of the peripheral side wall 11 constituting the crimping portion 10. Hereinafter, the description will focus on differences from the connection terminal 1 according to the first embodiment.

本実施形態において、周側壁１１には、第２開口１１ｂと第１開口１１ａとの間に変位点１１ｃが設定されている。この変位点１１ｃを境に、周側壁１１の内部空間の形状が変化する。具体的には、周側壁１１は、第２開口１１ｂから変位点１１ｃまでは断面形状が一定のままを維持するが、変位点１１ｃから第１開口１１ａにかけてテーパー状に拡幅して形成されている。第１開口１１ａの開口径、第２開口１１ｂの開口径、変位点１１ｃにおける内径、導体１０１の外径を比較すると、これらには、第１開口１１ａの開口径＞第２開口１１ｂの開口径＝変位点１１ｃにおける内径＞導体１０１の外径となる関係が存在している。   In the present embodiment, a displacement point 11c is set on the peripheral side wall 11 between the second opening 11b and the first opening 11a. The shape of the internal space of the peripheral side wall 11 changes with this displacement point 11c as a boundary. Specifically, the peripheral side wall 11 maintains a constant cross-sectional shape from the second opening 11b to the displacement point 11c, but is formed in a tapered shape from the displacement point 11c to the first opening 11a. . Comparing the opening diameter of the first opening 11a, the opening diameter of the second opening 11b, the inner diameter at the displacement point 11c, and the outer diameter of the conductor 101, the opening diameter of the first opening 11a> the opening diameter of the second opening 11b. = Inner diameter at displacement point 11c> Outer diameter of conductor 101 exists.

このようにして本実施形態によれば、周側壁１１の全域に限らず、第１開口１１ａ側の一部領域のみがテーパー形状に設定されるものであっても、第１の実施形態と同様、第１開口１１ａ側の開口サイズを大きく設定することができる。そのため、導体１０１の端部において複数本の素線がばらついたような状態であったとしても、圧着部１０への挿入の際に素線がはみ出しにくくなる。そのため、導体１０１の先端部を丁寧に整えずとも、挿入することができるので、挿入時の作業負担を低減することができる。これにより、リッツ線１００の挿入時における作業性の向上を図ることができる。   Thus, according to the present embodiment, not only the entire area of the peripheral side wall 11 but also only a partial region on the first opening 11a side is set in a tapered shape, the same as in the first embodiment. The opening size on the first opening 11a side can be set large. For this reason, even if a plurality of strands are scattered at the end of the conductor 101, the strands are difficult to protrude when inserted into the crimping portion 10. For this reason, the conductor 101 can be inserted without carefully arranging the tip, so that the work load during insertion can be reduced. Thereby, the workability | operativity at the time of insertion of the litz wire 100 can be aimed at.

なお、本実施形態にかかる周側壁１１は、導体の端子挿入方向における奥側位置から端子の第１開口にかけて周側壁が拡幅して形成されていればよく、第１の実施形態及び第２の実施形態に例示した形態以外にも種々の形態を選択することできる。   In addition, the peripheral side wall 11 concerning this embodiment should just be formed so that a peripheral side wall may be expanded from the back | inner side position in the terminal insertion direction of a conductor to the 1st opening of a terminal, and 1st Embodiment and 2nd Various forms other than the forms illustrated in the embodiments can be selected.

以上、本実施形態にかかる接続用端子について説明したが、本発明はこの実施形態に限定されることなく、その発明の範囲において種々の変更が可能である。   Although the connection terminal according to the present embodiment has been described above, the present invention is not limited to this embodiment, and various modifications can be made within the scope of the present invention.
