This technology discloses "realizing the conduction and disconnection of the first and third contact seats; the second moving contact is slidably assembled on the second contact seat or the third contact seat to realize the conduction and disconnection of the second and third contact seats";

[0030] When the existing GIS and GIS cable terminal connection devices are in use, the static contact is protected by a transition tube to prevent the static contact from being hit, and the transition tube is sealed by an end cap to reduce the probability of water entering the static contact. In order to ensure stability, the end cap and the pressure-resistant casing need to be fixedly connected to the transition tube by a number of bolts, which makes it time-consuming to disassemble and assemble the end cap or the pressure-resistant casing, and easily reduces the efficiency of disassembly and assembly of the conductive rod, resulting in a decrease in the testing efficiency of the device. Combined with actual use, this problem is obviously a real problem that is difficult to solve. In view of this, in order to solve this technical problem, a limit shaft and a fixed block are added to the application document.

At this time, the end cap 3 can be removed by moving up, and a fixing block 4 corresponding to the number of fixing grooves is set at the bottom end of the pressure-resistant casing, and the pressure-resistant casing is moved down so that the conductive rod is connected with the static contact. At this time, the fixing block 4 enters the limit box 5 through the fixing groove, and the fixing ring 12 is loosened.

The end cap 3 is easily moved up and down by the handle 15, thereby improving the portability of the end cap 3 when moving. The sealing ring 17 is convenient for sealing the connection between the end cap 3 and the transition tube 2. When external water vapor reaches the connection between the end cap 3 and the transition tube 2, it will be blocked by the sealing ring 17, thereby making the connection between the end cap 3 and the transition tube 2 have a higher sealing performance, thereby reducing the probability of external rainwater entering the transition tube 2 and causing short-circuit damage to the static contact, thereby improving the service life of the device.
