種に応じて通電時間を変更しなければならない。2. Description of the Related Art Generally, a fusion splicer has a structure in which a heating coil is embedded in a cylindrical sleeve. Thermoplastic resin pipes are inserted from both ends of this sleeve (joint body), and the heating coil is energized in this state. Then, after melting the inner circumference of the sleeve and the thermoplastic resin tube, the thermoplastic resin tubes are connected by cooling and hardening. By the way, in fusion splicing, sleeve diameter and
If the number of turns and the diameter of the heating coil are different, the optimum energization time is also different. Therefore, when fusing, the energization time must be changed according to the product type.

制御装置から通電した時に抵抗値をチェックすることで
品種が解り、それにより最適通電時間が解る。Therefore, in order to find out the optimum energization time according to the product type, there is a heating coil in which an identification resistor is provided in parallel. That is, if the resistance value of the resistance for identification is made to differ depending on the type of the fusion splicing joint, the type can be known by checking the resistance value when the fusion control device is energized, and the optimal energization time can be determined accordingly.

助接点ピンが立設されている構造であった。As a fusion-bonding joint provided with the above-mentioned resistance for identification, for example, one described in Japanese Patent Laid-Open No. 2-129493 is known. In this fusion splicer, cylindrical main contact pins connected to the heating coil are erected on terminals provided at both ends of the joint body, and inside the main contact pins are insulated from the main contact pins. And a resistance pin connected to the heating coil,
On the upper side of the resistance pin, the auxiliary contact pin is erected so as to be connected to the resistance pin and fitted in the inner circumference of the main contact pin in an insulated state.

The optimum fused state can be obtained by energizing according to the time.

雑になる。At the work site, since the resistance pin corresponding to the fusion joint is screwed into the terminal of each fusion joint, the construction at the work site takes time and there is a possibility that the resistance pin may be attached incorrectly. However, quality control becomes complicated.

ない。Since the resistance pin is provided for each of the fusion-bonded joints, the cost per fusion-bonded joint is relatively high. Moreover, since it is necessary to perform processing so that each pin can be attached to the terminal portion of the fusion-bonded joint, a normal fusion-bonded joint cannot be used as it is.
