Description of the invention (16) The electromagnetic force f acts to offset the direction of the electromagnetic counterforce F, thereby making the ground contact low. 9 Contact pressure required for closed circuit ^ ^ 6th embodiment In the 6th embodiment, as shown in Fig. 7, there is a flange portion 4 "as a tie member along the entire circumferential insulation barrier along the edge portion of the insulating rod 44 The side of the flange 20a is provided. The inside diameter of the flange portion 44a is larger than the outside diameter j of the insulation barrier 20 and the insulation rod 44 is arranged so that the flange portion 4 is placed on the insulation barrier 20 when the ground contact 9 is closed. The front end portion is arranged in a state of re-examination in the axial direction of the movable contact 13 on the ground contact side, that is, in a manner of over-lap. The other configurations are the same as those in the second embodiment described above. In the embodiment 6, due to the insulating barrier 2 The interior is insulated by the insulation product 44 from the outside, so that the insulation endurance can be improved, and at the same time, the part can be prevented from reducing the insulation endurance of the insulation caused by the contamination caused by foreign matter in the air.

Description of the invention (17) Configuration of touch and leave; operating mechanism, the operating mechanism connected to the other end of the aforementioned grounding guide extending from the aforementioned vacuum container via an insulating member; and grounding and testing The terminals can be connected to the grounding guide extending from the vacuum container in a relatively displaceable state; therefore, miniaturization and cost reduction can be expected, and at the same time, high-reliability and safety switching devices can be obtained. Furthermore, since the vacuum container is grounded, and the ground and test terminals are insulated from the vacuum container, it is not necessary to provide a separate sleeve or the like, which can simplify the configuration. Furthermore, one end of the grounding and testing terminal is connected to the other end side of the grounding conductor by a flexible conductor, and a connection portion between the grounding conductor and the flexible conductor is surrounded by a cylindrical insulation barrier. The reduced insulation distance allows the device to be made smaller. Furthermore, the vacuum container is made of a metal cylinder made of an insulating resin, and the grounding and test terminal is insulated from the cylinder groove, so that the insulating resin is integrally molded to the cylinder groove. The assembly of test terminals is no longer necessary, and productivity can be improved. Furthermore, one end of the ground and test terminal is formed by a ring shape surrounding the ground guide, and the flexible conductor is connected to one end of the ground and test terminal formed in a ring shape. Therefore, the flexible conductor can be arranged freely. The degree is increased, thereby ensuring the insulation distance to the frame that houses the operating mechanism. In addition, because the ground conductor penetrates the bottom of the bottomed cylindrical flange fixed to the barrel groove in an insulating manner, it is in a closed and flexible form II ^ ---- 1 ----- (Please read first Note on the back, please fill in this page again) This paper size is applicable to China National Standard (CNS) A4 (210 X 297 mm) 17 311526 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 480799 A7 B7 V. Description of the invention (18) For mounting, one end of the grounding and testing terminal is formed into a ring shape surrounding the flange, and a ring-shaped insulating elastic member is inserted between one end of the ringing grounding and testing terminal and the flange. Therefore, when the constituent parts of the vacuum container and the grounding and test terminals are molded from an insulating resin, the individual changes in the dimensions of the constituent parts can be absorbed by the deformation of the insulating elastic member. This eliminates the need for high-precision position matching of the component parts and grounding and test terminals in the metal mold, and as a result, the molding workability can be improved. Furthermore, since the insulating member and the insulating barrier are sealed by a flexible insulating member, it is possible to suppress a decrease in insulation resistance due to contamination of the insulating part in the air or adhesion of foreign matter. Furthermore, 'the U-shaped connection terminal connects one end to the other end side of the aforementioned ground conductor and is installed in a state where the axial direction of the aforementioned ground conductor is orthogonal', then the flexible conductor is connected to the other end of the aforementioned connection terminal, and the short-circuit current When the current flows, the electromagnetic force of the connection terminal and the state that the ground contact is opened and opened can be prevented when the electromagnetic backwash force acting on the ground conductor cancels the ground contact. Furthermore, the flange portion extends along the entire periphery of the edge portion of the insulating member toward the insulating barrier side and is formed to have an inner diameter larger than the outer diameter of the insulating barrier. The insulating member is configured to be configured when the ground conductor contacts the main body. In the case of a circuit conductor, the state where the front end of the sacral portion overlaps with the axial direction of the contact conductor before the insulation barrier is prevented, and thus the degradation of the creeping insulation caused by the pollution of the insulating portion in the air or the adhesion of foreign matter can be suppressed.
