The conventional connection method to be improved by the present invention is the fourth connection method.
As shown in the figure, the tip of the temperature fuse 7 and the tip of the leader wire 2 are overlapped, and the electrodes 10a and 10b of the DC resistance welding machine are pressurized from above and below to perform spot welding (FIG. 5A). It was connected. Connections using this point connection have considerable strength against tension caused by shock and vibration, but have low strength against bending and are susceptible to peeling and disconnection at the connection, and the wire diameter of the connection is large and requires two-hole insulation. It has drawbacks such as difficulty in accommodating it in the tube 8. The object of the present invention is to provide a welded connection method that does not have these drawbacks.

In the present invention, the temperature fuse 7 and the lead wire 2
is placed in the groove 15 of the grooved electrode plate 11, and the temperature fuse 7 is brought into contact with the lead wire 2 under pressure, so if plasma welding is performed in this state, the temperature fuse 7 will soften and melt. The soluble metal is extruded in the direction of the lead wire 2 and covers the tip thereof to form a welded joint 9 as shown in FIG. 5B. Since this welded joint 9 is front welded, it has sufficient strength against tensile and bending stresses caused by shock and vibration, and the size of the welded joint 9 is regulated by the groove 15, so that Hole insulation tube 8
There will be no problem in storing it inside the building. Therefore, it has the effect of achieving the purpose of the invention.
