るようになつていた。 A conventional buffer type switch of this type has a movable electrode reciprocably disposed on the axis of the fixed electrode so as to be connectable to the fixed electrode fixed to the inner end of the bushing, etc. A fixed cylinder is arranged around the outer periphery of the fixed electrode, and a piston is fixed to the outer periphery of the movable electrode to form a pressure chamber within the cylinder, and a rotary operation lever provided outside the switch case opens and closes the opening and closing path. By operating the movable electrode and the piston, the movable electrode and the piston are reciprocated through the motion converting mechanism, and as the piston moves, the internal pressure of the pressure chamber increases as the piston moves, especially during the opening operation, and an arc occurs between the two electrodes. It was designed to extinguish the arc by spraying gas inside the pressure chamber against it and actively stretching the arc.

来たす要因にもなつていた。 However, in this conventional buffer type switch, the fixed electrode and the cylinder are fixed to a fixed part in the switch, and the movable electrode and the piston are reciprocated within the cylinder in the direction toward or away from the fixed electrode. Therefore, when the base end of the movable electrode is directly pivoted to the tip of the operating lever that rotates as the operating lever outside the switch case opens and closes the circuit, The movable electrode is tilted by the rotational movement of the operating lever, and is separated from the axis of the fixed electrode, making it difficult to smoothly open and close the circuit. Therefore, in conventional switches, a complex motion conversion mechanism is interposed between the rotary operating lever and the movable electrode as described above, and the rotary motion of the rotary operating lever is converted into linear reciprocating motion of the movable electrode. It was configured to convert to . For this reason, the structure of the motion conversion mechanism is extremely complex, resulting in motion transmission loss, which is a major factor in increasing the manufacturing cost of the switch and also causing problems in the operation of the switching circuit.

にある。 This invention was devised to eliminate the above-mentioned defects in conventional buffer type switches. By swingably supporting the fixed electrode and cylinder on the fixed part of the switch so that it can follow the tilting movement without any trouble, the base end of the movable electrode can be moved as the rotating operation lever is operated. It can also be directly pivoted to the rotating operating lever, significantly simplifying the structure compared to conventional switches and contributing to a significant cost reduction. It is an object of the present invention to provide a new buffer type switch which can smoothly perform opening/closing operation by reducing transmission loss of motion between the two.

よく消弧される。 In this manner, when the movable electrode 12 and the piston 16 move and the movable electrode 12 separates from the fixed electrode 7, an arc is generated between the tips of both the electrodes 7 and 12. At this time, as the piston 16 moves, the internal pressure of the pressure chamber 19 increases, so that the gas in the pressure chamber 19 flows through the communication hole 18a of the partition plate 18, as shown by the arrow in FIG. The gas is ejected from the gas outlet 20a of the nozzle 20, and is vigorously blown against the arc occurring between the electrodes 7 and 12.

In this case as well, the movable electrode 12 and the cylinder 15 follow the tilting movement of the movable electrode 12 due to the rotation of the operating lever 11, and the fixed electrode 7 and the cylinder 15 are swung about the support pin 8, as in the case of opening the circuit. The piston 16 is a fixed electrode 7
and the second cylinder 15 is moved to the right on the same axis without fear of separating from the axis.
As shown in the figure, the movable electrode 12 is inserted into contact with the fixed electrode 7, resulting in a closed circuit state.

る。 As described in detail above, this invention is designed so that even if the movable electrode to which the piston is fixed is tilted with respect to the axis of the fixed electrode due to the opening operation, the switch between the fixed electrode and the cylinder can be moved without support. Since it is swingably supported on the fixed part of the movable electrode, the base end of the movable electrode can be directly pivoted to the operating lever that is rotated when the rotary operating lever is operated. The structure is significantly simplified compared to conventional devices, contributing to a significant cost reduction, and the transmission loss of motion between the rotary operating lever and the movable electrode is reduced, allowing smooth opening and closing operation. It has great effects.
