きるものである。DESCRIPTION OF THE INVENTION To achieve this object, the present invention provides a wire connector made of a shape memory alloy. With this configuration, in the unlikely event that heat is generated in the connection due to an incomplete connection, the connection can be tightened to prevent accidents caused by the incomplete connection.
実施例の説明
以下、本発明をその一実施例を示す第１図、第２図を参
考に説明する。DESCRIPTION OF EMBODIMENTS The present invention will be described below with reference to FIGS. 1 and 2, which show one embodiment thereof.
第１図において、１は電線接続具で電線の芯線を挿入す

第１図の様な形状に電線接続具として構成されたもので
ちる。電線接続は第２図のように、電線３，４の芯線５
，６を電線接続具１の開口部２ａ、２ｂに両方から挿入
し、電線接続具１をねじることによって接続される。In Fig. 1, reference numeral 1 denotes a wire connector which is provided with openings 2a and 2b into which the core wire of the wire is inserted, and the wire connector 1 is made of a shape memory alloy such as Ni-Ti or A#-Zn-Cu. It is constructed as an electric wire connector in the shape shown in Fig. 1. The wire connection is as shown in Figure 2, using the core wire 5 of the wires 3 and 4.
, 6 into the openings 2a and 2b of the wire connector 1 from both sides, and the wire connector 1 is twisted to connect.
そして電線接続具１の電線を挿入する開口部２ａ、２ｂ
は約５０℃にて相変態をして、開口部が挿入電線の芯線
よりも小さくなるように形状記憶処理されているもので
ある。Openings 2a and 2b into which the wires of the wire connector 1 are inserted
undergoes a phase transformation at approximately 50° C., and is subjected to shape memory treatment so that the opening becomes smaller than the core wire of the inserted electric wire.
このように構成すると、万一電線接続部のねじりが不完

って当然、この部分で発熱し、約５０°Ｃになれば形状
記憶合金で作られた電線接続具は相変態し、芯線２ａ、
２ｂを締め付けることになるので発熱を解消することに
なる。With this configuration, in the unlikely event that the wire connection part is not fully twisted, current will naturally flow through the wire, causing heat to be generated in this part, and if the temperature reaches approximately 50°C, the shape memory alloy will heat up. The wire connector made undergoes a phase transformation, and the core wire 2a,
2b will be tightened, which will eliminate heat generation.
なお、第２図の形状でねじシをより加える方向に形状記
憶処理しておくことによっても同じ効果を得ることがで
きる。また、よシミ気的な接続を確実にするため開口部

能である。Note that the same effect can also be obtained by performing shape memory processing in the direction of adding more threads in the shape shown in FIG. Furthermore, it is of course possible to line the inner surfaces of the openings 2a and 2b with a copper plate in order to ensure a stain-free connection.
発明の効果
以上のように本発明の電線接続装置は、接続部の発熱に
よって、電線の芯線を締付ける方向に形状記憶処理され
た形状記憶合金で構成されているので、万一接続不完全
