Description
本発明は圧着端子を加熱圧着して電線と接合する接続方法及びそれに用いられる圧着端子に関する。 The present invention relates to a connection method in which a crimp terminal is thermocompression bonded and joined to an electric wire, and a crimp terminal used therefor.
従来は特開２００２−１３４２４６号公報，特開２００２−９３４７８号公報にあるように、一対の対向する先端が平らな電極を用いて通電熱圧着をする方法であり、また、平らな電極の一方の電極にスリット又は両端に壁を設けて、圧着端子の両端が水平方向に広がることを防止すると共に、圧着端子の両端の電線が潰れるように配慮した加圧方式であった。 Conventionally, as disclosed in JP-A-2002-134246 and JP-A-2002-93478, a pair of opposed tips are flattened by thermoelectric pressure bonding, and one of the flat electrodes is used. The electrode was provided with slits or walls at both ends to prevent both ends of the crimp terminal from spreading in the horizontal direction, and the pressure system was designed so that the electric wires at both ends of the crimp terminal were crushed.
従来の平らな電極を用いた加熱圧着方式では、対向する先端が平らな電極を用いて圧着端子を加圧変形させることにより、圧着端子の平らな形状に潰された両端部分は、内部の電線が十分に変形し難く、カシメ性能が劣る等の課題があった。また、平らな電極の一方の電極にスリット又は両端に壁を設けて、圧着端子の両端が水平方向に広がることを防止する通電熱圧着方法では、圧着端子の両端部は３方向から圧力を受けるため、内部の電線は変形し難く、カシメ性能が劣り、電線の接続強度の低下や電気抵抗値の上昇が発生する等の課題があった。 In the conventional thermocompression bonding method using flat electrodes, both ends of the crimped terminal that are crushed into a flat shape are deformed by pressing and deforming the crimping terminal using an electrode having a flat tip. However, it is difficult to deform sufficiently, and there are problems such as poor caulking performance. Moreover, in the energization thermocompression bonding method in which one end of a flat electrode is provided with slits or walls at both ends to prevent the both ends of the crimp terminal from spreading in the horizontal direction, both ends of the crimp terminal receive pressure from three directions. For this reason, the internal electric wires are difficult to deform, the caulking performance is inferior, and the connection strength of the electric wires is reduced and the electric resistance value is increased.
本発明は、電線と圧着端子とが確実に接合される圧着端子の接合方法及びそれに用いられる圧着端子を提供することを目的とする。 An object of this invention is to provide the bonding method of the crimp terminal in which an electric wire and a crimp terminal are joined reliably, and the crimp terminal used for it.
本発明では、上記課題を解決するために、被覆された電線が挿入された圧着端子が、一対の電極で挟まれ、前記一対の電極に流される電流によって発生するジュール熱で加熱され、前記一対の電極に押し付けられ、前記圧着端子に挿入された前記電線と接続され、前記圧着端子の両端に前記電線とは異なるダミー電線を配置したことを特徴とする。 In the present invention, in order to solve the above-mentioned problem, a crimp terminal into which a covered electric wire is inserted is sandwiched between a pair of electrodes and heated by Joule heat generated by a current flowing through the pair of electrodes, A dummy electric wire different from the electric wire is disposed at both ends of the crimping terminal, being pressed against the electrode and connected to the electric wire inserted into the crimping terminal.
本発明によれば、電線の接続性能を必要とする電線を圧着端子の中央部分に圧着し、接続性能を必要としないダミー電線を圧着端子の両端に圧着することにより、電線の接続性能を低下させることなく、通電加熱圧着を行うことができる。 According to the present invention, an electric wire that requires connection performance of the electric wire is crimped to the center portion of the crimp terminal, and a dummy electric wire that does not require connection performance is crimped to both ends of the crimp terminal, thereby reducing the connection performance of the electric wire. It is possible to perform energization heating and pressure bonding without causing them.
本発明では、圧着端子に電線を挿入する工程において、予め挿入する電線の断面積と本数の積によって選択する圧着端子のサイズより、大きいサイズの圧着端子を選択し、不足する電線の本数分に相当するダミーの電線を挿入すること、および、挿入するダミーの電線が潰された圧着端子の両端に位置する様に予め圧着端子に挿入することによって、潰された圧着端子の接続強度や電気抵抗値が十分に得られない両端部分は接続性能が要求されないために、性能を必要とする電線と区別することができることを特徴とする通電加熱圧着方法であり、それに用いられる圧着端子である。 In the present invention, in the step of inserting the electric wire into the crimp terminal, select a crimp terminal having a size larger than the size of the crimp terminal to be selected according to the product of the cross-sectional area and the number of wires to be inserted in advance, and reduce the number of wires to be insufficient. By inserting the corresponding dummy electric wire and inserting the dummy electric wire into the crimping terminal in advance so that the dummy electric wire to be inserted is positioned at both ends of the crimping terminal, the connection strength and electric resistance of the crimped crimping terminal Since both end portions where a value is not sufficiently obtained are not required for connection performance, this is an energization heating crimping method characterized in that it can be distinguished from an electric wire that requires performance, and is a crimp terminal used for it.
本発明によれば、電線の接続性能を必要とする電線を圧着端子の中央部分に圧着し、接続性能を必要としないダミー電線を圧着端子の両端に圧着することにより、電線の接続性能を低下させることなく、通電加熱圧着を行うことができる。 According to the present invention, an electric wire that requires connection performance of the electric wire is crimped to the center portion of the crimp terminal, and a dummy electric wire that does not require connection performance is crimped to both ends of the crimp terminal, thereby reducing the connection performance of the electric wire. It is possible to perform energization heating and pressure bonding without causing them.
圧着端子の電線との接続部の中でその変形された両端部は、接続強度や電気抵抗値が十分に得られないが、逆に、この両端部には接続性能が要求されない。従って、このような部位にダミー電線を配置するものである。つまり、本発明では、性能を必要とする電線と性能を必要としないダミー電線とを圧着端子内に混在させることに特徴がある。さらに、潰された際に、ダミー配線がその両端部に配置されていることを特徴とする。 The deformed both ends of the connecting portion of the crimp terminal with the electric wire cannot obtain a sufficient connection strength and electrical resistance value, but conversely, the connecting performance is not required for the both ends. Therefore, a dummy electric wire is arranged in such a part. That is, the present invention is characterized in that electric wires that require performance and dummy electric wires that do not require performance are mixed in the crimp terminal. Furthermore, when crushed, the dummy wiring is arranged at both ends thereof.
