Description

本開示は、圧着端子、及び端子付き電線に関するものである。 The present disclosure relates to crimp terminals and electric wires with terminals.

従来、電線の芯線に圧着される圧着端子としては、電線の芯線を包み込むように変形されることで該芯線に圧着される板状の圧着部と、その圧着部の内面に凸設された凸部とを備えたものがある（例えば、特許文献１参照）。この圧着端子は、圧着部から延出されて折り曲げられた折り曲げ部を備え、前記凸部は、折り曲げ部に連なって設けられることで製造が容易とされている。また、凸部は、折り曲げ部から芯線の延在方向に沿って延びる延在部と、その延在部と交差する方向に延びる交差部とを有し、圧着状態では特に交差部が芯線に食い込むように配置されることになる。よって、特に芯線がアルミニウム系の金属からなる場合等、芯線の表面の酸化被膜が交差部によって破壊されて該表面の電気抵抗が小さくなり、芯線の良好な電気接続が確保される。また、上記のような圧着端子としては、圧着部の内面に、芯線の延在方向と直交する方向に沿って延びる溝が設けられたものがある（例えば、特許文献１（図２３〜図２５）参照）。 Conventionally, as a crimp terminal that is crimped to the core wire of an electric wire, a plate-shaped crimping portion that is crimped to the core wire by being deformed so as to wrap the core wire of the electric wire and a convex portion that is convexly provided on the inner surface of the crimping portion. Some are provided with a part (see, for example, Patent Document 1). The crimp terminal includes a bent portion that extends from the crimped portion and is bent, and the convex portion is provided so as to be connected to the bent portion, so that manufacturing is easy. Further, the convex portion has an extending portion extending from the bent portion along the extending direction of the core wire and an intersecting portion extending in a direction intersecting the extending portion, and the intersecting portion particularly bites into the core wire in the crimping state. Will be arranged like this. Therefore, especially when the core wire is made of an aluminum-based metal, the oxide film on the surface of the core wire is broken by the intersection, the electrical resistance of the surface is reduced, and a good electrical connection of the core wire is ensured. Further, as the crimping terminal as described above, there is a crimping terminal provided with a groove extending along a direction orthogonal to the extending direction of the core wire on the inner surface of the crimping portion (for example, Patent Document 1 (FIGS. 23 to 25). )reference).

特開２０１８−８５２３２号公報Japanese Unexamined Patent Publication No. 2018-8232

しかしながら、上記のような圧着端子では、圧着状態の芯線が抜け易いという問題があった。特に、上記したように、凸部が芯線の延在方向に沿って延びる延在部を有する場合、芯線の延在部に当接した部位が抜け易くなる。 However, the crimp terminal as described above has a problem that the core wire in the crimped state is easily pulled out. In particular, as described above, when the convex portion has an extending portion extending along the extending direction of the core wire, the portion in contact with the extending portion of the core wire is easily removed.

本発明は、上記課題を解決するためになされたものであって、その目的は、芯線の抜けが抑制される圧着端子、及び端子付き電線を提供することにある。 The present invention has been made to solve the above problems, and an object of the present invention is to provide a crimp terminal in which disconnection of a core wire is suppressed and an electric wire with a terminal.

本開示の圧着端子は、電線の芯線を包み込むように変形されることで該芯線に圧着される板状の圧着部と、前記圧着部の内面に凸設された凸部とを備えた圧着端子であって、前記圧着部の内面には、交差する内面溝が設けられる。 The crimp terminal of the present disclosure is a crimp terminal provided with a plate-shaped crimping portion that is crimped to the core wire by being deformed so as to wrap around the core wire of the electric wire, and a convex portion that is convexly provided on the inner surface of the crimping portion. The inner surface of the crimping portion is provided with intersecting inner surface grooves.

本開示の端子付き電線は、前記圧着端子と、該圧着端子が圧着された前記電線とを備える。 The electric wire with a terminal of the present disclosure includes the crimp terminal and the electric wire to which the crimp terminal is crimped.

本開示の圧着端子、及び端子付き電線によれば、芯線の抜けが抑制される。 According to the crimp terminal and the electric wire with a terminal of the present disclosure, the core wire is suppressed from coming off.

次に、上記のように構成された端子付き電線１１の作用について説明する。
図４に示すように、圧着される前の状態の圧着部１５の内側に芯線１２ａ，１３ａが収容され、図４中、矢印Ｘで模式的に示すように、芯線１２ａ，１３ａを包み込むように圧着部１５が変形されることで、圧着端子１４は芯線１２ａ，１３ａに圧着される。この端子付き電線１１では、凸部１６の特に交差部１９が芯線１２ａ，１３ａに食い込むように配置されることで、芯線１２ａ，１３ａの表面の酸化被膜が破壊されて該表面の電気抵抗が小さくなり、芯線１２ａ，１３ａの良好な電気接続が確保される。 Next, the operation of the electric wire 11 with a terminal configured as described above will be described.
As shown in FIG. 4, the core wires 12a and 13a are housed inside the crimping portion 15 in the state before being crimped, and as shown schematically by the arrow X in FIG. 4, the core wires 12a and 13a are wrapped around the core wires 12a and 13a. By deforming the crimping portion 15, the crimping terminal 14 is crimped to the core wires 12a and 13a. In the electric wire 11 with terminals, the convex portion 16 in particular, the intersecting portion 19 is arranged so as to bite into the core wires 12a and 13a, so that the oxide film on the surface of the core wires 12a and 13a is destroyed and the electric resistance of the surface is reduced. As a result, good electrical connection of the core wires 12a and 13a is ensured.

次に、上記実施形態の効果を以下に記載する。
（１）圧着部１５の内面１５ａには、交差する内面溝２０が設けられるため、例えば、単に一方向に沿って延びる内面溝が設けられた場合に比べて、圧着状態の芯線１２ａ，１３ａの抜けが抑制される。 Next, the effects of the above embodiment will be described below.
(1) Since the inner surface 15a of the crimping portion 15 is provided with the intersecting inner surface grooves 20, for example, the core wires 12a and 13a in the crimped state are provided as compared with the case where the inner surface grooves extending only in one direction are provided. The omission is suppressed.

（２）内面溝２０は、平行な複数の溝同士が交差する網目状に設けられるため、芯線１２ａ，１３ａの抜けがより抑制される。
（３）内面溝２０は、該内面溝２０を構成する全ての溝が芯線１２ａ，１３ａの延在方向と交差する方向に沿って延びるように設けられるため、芯線１２ａ，１３ａの抜けがより抑制される。 (2) Since the inner surface grooves 20 are provided in a mesh shape in which a plurality of parallel grooves intersect with each other, the core wires 12a and 13a are further suppressed from coming off.
(3) Since the inner surface groove 20 is provided so that all the grooves constituting the inner surface groove 20 extend along the direction intersecting the extending direction of the core wires 12a and 13a, the core wires 12a and 13a are further suppressed from coming off. Will be done.

（４）内面溝２０は、圧着部１５の内面１５ａの全領域に設けられるため、芯線１２ａ，１３ａの抜けがより抑制される。
（５）凸部１６が設けられた領域を含めない圧着部１５の内面１５ａの面積は、凸部１６の表面積よりも大きく設定されるため、広い圧着部１５の内面１５ａの全領域に設けられた内面溝２０によって芯線１２ａ，１３ａの抜けが効果的に抑制される。 (4) Since the inner surface groove 20 is provided in the entire area of the inner surface 15a of the crimping portion 15, the core wires 12a and 13a are further suppressed from coming off.
(5) Since the area of the inner surface 15a of the crimping portion 15 not including the region where the convex portion 16 is provided is set to be larger than the surface area of the convex portion 16, it is provided in the entire region of the inner surface 15a of the wide crimping portion 15. The inner groove 20 effectively suppresses the core wires 12a and 13a from coming off.

（６）圧着端子１４は圧着部１５から延出されて折り曲げられた折り曲げ部１７を備え、前記凸部１６は、折り曲げ部１７に連なって設けられるため、例えば、別体の凸部を圧着部１５に固定して設ける場合に比べて、凸部１６を容易に設けることができる。 (6) The crimp terminal 14 includes a bent portion 17 that extends from the crimping portion 15 and is bent. Since the convex portion 16 is provided so as to be connected to the bent portion 17, for example, a separate convex portion is crimped. The convex portion 16 can be easily provided as compared with the case where the convex portion 16 is fixedly provided.
