[0002] In recent years, with the continuous optimization of power grid construction, the two-remote control and ordinary switches that were originally widely used have been gradually replaced by three-remote control switches.

[0003] However, the three-remote switches currently put into operation in large quantities only use one layer of sealing ring for sealing design between the terminal cable aviation plug and the interface, which has poor overall sealing performance and poor water seepage resistance, causing the joint contacts to be damp and rusted, which may affect the signal transmission rate at the least and cause the three-remote switch to refuse to operate remotely at the worst.

[0004] In addition, the existing three-shake switch terminal's aviation plug and socket usually use a spiral connection mode, which cannot be quickly installed and disassembled, causing great trouble to the dispatchers' work. There is a situation where the sealing ring is not sealed tightly due to the plug not being tightened properly, which seriously affects the safe and stable operation of the power grid.

[0005] The above contents are only used to assist in understanding the technical solution of the present invention, and do not constitute an admission that the above contents are the closest prior art. Summary of the invention

[0041] 1. The present invention gradually compresses the tensioning spring through the first clamping block and drives the telescopic rod to move along the guide groove until the second clamping block passes over the first clamping block. The first clamping block moves to the side of the second clamping block under the elastic force of the tensioning spring, so that the second clamping block is locked.

[0043] 3. In the present invention, under the reverse thrust of the telescopic rod on the inclined transition groove, the sleeve drives the plug body to be further inserted toward the interface body, and the plug body drives the second sealing ring with a certain toughness to further tighten the open end of the interface body. At the same time, the plug body drives the first sealing ring with a certain toughness to further tighten one end inside the interface body through the insertion block. At this time, the second clamping block is located at the end of the guide groove, thereby further improving the anti-water seepage effect of the plug and the interface.

[0044] 4. The present invention rotates the rotating sleeve in the opposite direction so that the telescopic rod enters the third groove from the clamping groove through the transition groove and the first groove in sequence. When the telescopic rod enters the third groove, the fourth inclined surface drives the first lifting block to move upward through the second inclined surface. The first lifting block drives the first clamping block to move along the accommodating groove through the telescopic rod and gradually compresses the tightening spring, so that the first clamping block that originally positioned one end of the second clamping block is separated from the second clamping block. At this time, the plug body is pulled out along the interface body to complete the disassembly work between the plug and the interface. The entire disassembly process is simple and fast, which greatly improves the work efficiency of the maintenance personnel. BRIEF DESCRIPTION OF THE DRAWINGS

The first sealing ring 213 is made of rubber material.

[0081] Furthermore, Figure 6 , Figure 9-12 As shown, the adjustment component 22 includes:

[0082] The sleeve 221 is fixedly connected to one end of the plug body 211 located at the plug block 212, and a gap for accommodating the interface body 11 is provided between the sleeve 221 and the plug block 212;

[0086] The second sealing ring 225 is also made of rubber material, and both the first sealing ring 213 and the second sealing ring 225 have high toughness.

[0087] Among them, Figure 9-10 As shown, a plurality of first grooves 2211 are provided at equal angles at one end of the sleeve 221, and the first grooves 2211 correspond to the telescopic rods 122 one by one, and are used to accommodate the telescopic rods 122;

[0088] A plurality of second grooves 2221 are provided at equal intervals at one end of the rotating sleeve 222. The second grooves 2221 correspond to the first grooves 2211 one by one and are used to cooperate with the first grooves 2211 to accommodate the telescopic rod 122.

[0090] In addition, if Figure 9-12 As shown, a lifting mechanism 224 for lifting the telescopic rod 122 is provided at one end of the second groove 2221;

[0091] A transition groove 2222 for tightening the telescopic rod 122 and a pressing groove 2223 for accommodating the telescopic rod 122 are sequentially provided inside the rotating sleeve 222 and at the end of the second groove 2221 on the side opposite to the lifting mechanism 224, and the transition groove 2222 is arranged obliquely.

[0092] As an improvement, Fig. 9 As shown, the lifting mechanism 224 includes:

[0094] a fourth inclined surface 2242, provided on a side of the second lifting block 2241 facing the second groove 2221, and used for adjusting the position of the first clamping block 121;

[0095] The third groove 2243 is provided at one side of the second lifting block 2241 and is used to accommodate the telescopic rod 122 . The third groove 2243 is flush with the second groove 2221 .

[0096] It should be noted that: Figure 7-Figure 8 As shown, in the specific implementation process of the present invention, initially, one end of the first card block 121 is located inside the guide groove 111 under the elastic force of the tightening spring 123. When the plug body 211 is installed, the plug body 211 is held and the plug block 212 is inserted into the interface body 11. During this process, the second card block 214 on one side of the plug block 212 gradually moves along the guide groove 111. When the second card block 214 moves to contact the first inclined surface 1211, the third inclined surface 2141 gradually pushes the first card block 121 to move along the accommodating groove 112 through the first inclined surface 1211. The first clamping block 121 gradually compresses the tensioning spring 123 and drives the telescopic rod 122 to move along the guide groove 113 until the second clamping block 214 passes over the first clamping block 121. The first clamping block 121 moves to the side of the second clamping block 214 under the elastic force of the tensioning spring 123, so that the second clamping block 214 is locked. At this time, the first sealing ring 213 is pressed against one end of the interface body 11 by the plug block 212, completing the preliminary sealing between the plug and the socket, so that the installation of the plug body 211 and the interface body 11 can be completed by only plugging and unplugging, and the installation speed is fast.

[0097] like Figure 5-Figure 7 , Fig.12 As shown, during the process that the plug body 211 drives the plug block 212 to be inserted into the interface body 11, the plug body 211 also synchronously drives the sleeve 221 to move along the outside of the interface body 11, and the sleeve 221 drives the rotating sleeve 222 to move, so that the first groove 2211 and the second groove 2221 are gradually inserted into the telescopic rod 122, until the end of the second groove 2221 moves to contact the telescopic rod 122, at this time, the second sealing ring 225 contacts the open end of the interface body 11 and the second block 214 just passes over the first block 121, so that a double-layer sealing design can be achieved between the plug and the interface, and the sealing effect is good;

[0098] like Figure 5 , Figure 9-10As shown, the rotating sleeve 222 is then rotated around the plug block 212, so that the telescopic rod 122 transitions to the pressing groove 2223 along the inclined transition groove 2222. In this process, under the reverse thrust of the telescopic rod 122 on the inclined transition groove 2222, the sleeve 221 drives the plug body 211 to be further inserted toward the interface body 11, and the plug body 211 drives the second sealing ring 225 with a certain toughness to further tighten the open end of the interface body 11. At the same time, the plug body 211 drives the first sealing ring 213 with a certain toughness to further tighten one end inside the interface body 11 through the plug block 212. At this time, the second clamping block 214 is located at the end of the guide groove 111, thereby further improving the waterproof effect of the plug and the interface.

[0099] like Fig. 9 , Figure 11-Figure 12 As shown, when the plug and the interface need to be disassembled, the rotating sleeve 222 is rotated in the opposite direction, so that the telescopic rod 122 enters the third groove 2243 from the clamping groove 2223 through the transition groove 2222 and the first groove 2211 in sequence. In the process of the telescopic rod 122 entering the third groove 2243, the fourth inclined surface 2242 drives the first lifting block 124 to move upward through the second inclined surface 1241, and the first lifting block 124 drives the first clamping block 121 to move along the accommodating groove 112 through the telescopic rod 122 and gradually compresses the tightening spring 123, so that the first clamping block 121 that originally positioned one end of the second clamping block 214 is separated from the second clamping block 214. At this time, the plug body 211 is pulled out along the interface body 11 to complete the disassembly work between the plug and the interface. The entire disassembly process is simple and fast, which greatly improves the work efficiency of the maintenance personnel.
