At the contact portion between the fixed connector 3as3b and the blade 4, it is necessary to maintain a specified contact pressure so that not only the normal rated current can be passed, but also the short circuit current can be passed for a short time. For this reason, a contact spring 8 has conventionally been provided near the contact portion of the blade 4, as shown in FIG. That is, first, a collar 9 is sandwiched between two blades 4, and a contact spring 8 made of a washer 1011 and a compression coil spring is placed on the outside of one grade from the grade side, and a washer 10b that presses the end of this contact spring 8.
overlap in order. Next, from the washer 10b side, the girth 11 is contacted with these two grade 4 sheets, the spring 8, the collar 9,
It was inserted through the washers 10 a e 10 b, and two nuts 12 were screwed together on the outside of the opposite blade, and the double nut effect was used to fix the blade.

Figures 5 and 6 show disconnector 1 closed and disconnector 1 open, respectively.
In FIG. 5, the fixed contact 3b and the blade 4 are in contact, so the tension spring 13 is extended and the tension link 14 is open, and in FIG. 6, the fixed contact 3b and the blade 4 are in contact. Since the tension spring 13 is in the "open" state where the disconnector 1 is separated, the tension spring 13 is compressed and the angle formed by the tension link 14 becomes small.
The distance between the contact parts of the two blades is maintained at a predetermined dimension, and the operability during the "close 2" operation is made into an inner groove.
