付構造上における制約が大きい。Problems to be Solved by the Invention In the conventional method of fixing a thermal fuse to a terminal, there is a gap between the thermal fuse inserted into a terminal hole of the terminal and a terminal wall to be contacted, and when a lead wire is fitted and fixed. Since the lead wire is damaged and the thermal fuse is installed openly, it is susceptible to temperature changes due to the ambient temperature and wind flow, and the temperature fuse operating level is likely to vary widely due to abnormal detection, resulting in temperature fluctuation. There are great restrictions on the selection of the operating temperature of the fuse and the mounting structure.

にくいように簡易密閉にすることにある。Means for Solving the Problems A solution for the problem according to the present invention is to provide a method for attaching a thermal fuse to a terminal, the method in which the lead wire of the thermal fuse is fixed by fitting and the terminal is openly mounted. It is an object of the present invention to provide a more reliable fixing method of the thermal fuse by attaching a resin cover fixed by a hook to the thermal fuse, and to provide a simple sealing so that the thermal fuse is hardly affected by surroundings.

ミナルに固定する。Operation There are three holes on the upper surface of the terminal, the resin cover has a corresponding claw portion, and the resin cover is hooked and fixed by inserting the claw portion into the hole of the terminal. The resin cover is fixed to the terminal and, at the same time, presses the thermal fuse element portion inserted into the terminal hole of the terminal, and simultaneously fixes the entire thermal fuse to the terminal.

As shown, the resin cover is provided with three claws (5a) corresponding to the holes of the terminal.

押える事が出来る。In addition, the thermal fuse is entirely covered with a resin cover, fixed to the terminal and has a built-in shape, so it is less susceptible to ambient temperature and wind flow, resulting in poor contact when inserting wires into the terminal. The temperature rise due to heat generation can be detected from the ambient temperature of the terminal resin part or thermal fuse insertion hole, and the variation in the detection operation of the thermal fuse when the thermal fuse inserted into the insertion hole becomes unstable with the terminal becomes unstable. I can hold it down.

づを防止出来る。Furthermore, the lead wire of the thermal fuse is shielded from the outside by the resin cover, and further fixed to the terminal by the resin cover, so that the lead wire can be fixed temporarily, and to the lead wire that is likely to occur when fitting and fixing. Can be prevented from being damaged.

ある。Effect of the Invention As described above, according to the present invention, a thermal fuse for preventing heat, smoke, ignition, etc. due to poor contact at the time of wire insertion into a terminal is more securely fixed to the terminal, By making it less susceptible to the influence of temperature, wind flow, etc., the detection at the time of abnormality is stabilized, and there are many advantages in improving safety and reliability.
