産業上の利用分野
本発明は、空気調和機等大電流機器に使用される電線接
続具のネジ締付は不良などから起る接続部での発熱を解
消する電線接続装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is directed to an electric wire connection that eliminates heat generation at the connection part caused by poor screw tightening of electric wire connectors used in large current equipment such as air conditioners. It is related to the device.
従来例の構成とその問題点
空気調和機等大電流機器に使用される電線接続具は、電
線の先端に圧着端子を取り付けて、これをネジと座金で
締付ける構造が一般的である。Conventional Structures and Problems Wire connectors used in large current devices such as air conditioners generally have a structure in which a crimp terminal is attached to the tip of the wire, and this is tightened with a screw and washer.
しかし、かかる構成は万一ネジの締付は不完全が発生す
ると、電流によってこの部分が発熱し、電線接続部をこ
がし、影響が除々に拡大、最後には火災などの大事故に
至るなどの不具合があった。However, with this configuration, if the screws are not tightened properly, the electric current will generate heat in this part, burn the wire connection, and the effects will gradually expand, eventually leading to a major accident such as a fire. There was a problem.
発明の目的
本発明はこのような問題を解決するもので、万一電線接
続部に不備が生じても、これから起る発熱を未然に解消
できる電線接続具を提供しようとするものである。OBJECTS OF THE INVENTION The present invention is intended to solve such problems, and to provide a wire connector that can eliminate the heat generation that would otherwise occur even if a defect occurs in the wire connection portion.
発明の構成
この目的を達成するために本発明は、電線接続具に形状
記憶合金からなる座金をもって構成したものである。DESCRIPTION OF THE INVENTION To achieve this object, the present invention includes a wire connector equipped with a washer made of a shape memory alloy.
この構成によって、万一電線接続部のネジ締付は不備で

ジ緩みが進行することがないように、また、電線や圧着
端子を締付ける方向に形状記憶合金からなる座金が変形
し、ネジ締め不備からくる事故を未然に防止することが
できるものである。With this configuration, in the unlikely event that the screws at the wire connection part are not tightened properly and heat is generated due to current in this part, the screws will not loosen any further, and the wires and crimp terminals will be tightened in the correct direction. It is possible to prevent accidents caused by improper screw tightening due to deformation of the washer made of shape memory alloy.

Shape memory treatment has been performed so that the phase changes and threads appear on the top and bottom, and at temperatures below about 200 sq. ft., it is usually in an almost flat state as shown in Figure 2.

When the temperature reaches approximately 50'C, the washer made of gold on the shape memory stand undergoes a phase transformation and is twisted up and down to press the crimp terminal and at the same time apply force to prevent the screw from loosening. , it will eliminate fever.

全確実な電線接続具を提供することができる。Effects of the Invention The electric wire connector of the present invention includes a washer made of a shape memory alloy that has been subjected to shape memory treatment to prevent the screw from loosening due to the heat generated in the connecting portion in the event that the electric wire connecting portion fails. Therefore, in the unlikely event that the screws are not fully tightened, the electric current will generate heat at the connection, twisting the washer downwards, pressing the crimp terminal, and at the same time applying force to prevent the screw from loosening. Therefore, it is possible to provide a safe and reliable electric wire connector that eliminates heat generation.
