The description in this part is only exemplary and explanatory, and should not have any restrictive effect on the protection scope of the present invention.

[0028] Embodiment 1:

[0029] Such as Figure 1—4 shows: a self-power-off high-voltage ceramic capacitor, comprising a capacitor core 1, a plurality of fitting access terminals 2 are fixed on the top of the capacitor core 1, a circuit connection plug 3 is adapted to be plugged on the top of the fitting access terminal 2, the circuit connection plug 3 is electrically connected to a power line 5, both ends of the circuit connection plug 3 are connected to insulating plates 4, a controllable self-power-off mechanism 6 is installed on one side of the capacitor core 1, the controllable self-power-off mechanism 6 is composed of a shell component 7, a telescopic component 8, and a control component 9, the shell component 7 comprises a main shell 71, the upper and lower ends of the main shell 71 are respectively connected to a limit tube 72 and a control component 9, and a base 73 is installed on the inner end surface of the main shell 71, One end of the base 73 is connected to a tube body 74, and a movable groove 75 is provided on the side of the base 73. The telescopic component 8 includes a limit block 81, and the limit block 81 is connected to one end of the push rod of the electric push rod 92 in the control component 9. A clamping groove 82 is provided on the limit block 81, and one end of a connecting claw 84 is inserted in the clamping groove 82. The claw 84 is rotatably installed in the main shell 71 through a pin shaft 85. The other end of the claw 84 is adapted to be clamped on the side of a push rod 86. The push rod 86 is slidably inserted in the limit tube 72 and the tube body 74. One end of the push rod 86 is connected to the insulating plate 4. A spring 87 is installed between the push rod 86 and the base 73, which can remotely control the electric push rod. The extension and retraction of the rod 92 drives the claw 84 to rotate, and the elastic energy storage of the spring 87 is released to drive the push rod 86 to pop out quickly with low power consumption, driving the circuit connection plug 3 to separate from the matching access terminal 2, and realizing the remote power-off function. One end of the claw 84 is slidably inserted in the movable groove 75, and the movable groove 75 is provided to enable the claw 84 to rotate smoothly within a certain range, thereby clamping or releasing the push rod 86. The bottom end of the base 73 is provided with a slot structure for slidingly installing the limit block 81, and the limit block 81 can move stably under the limit of the base 73. The spring 87 is installed on the inner side of the tube body 74, and the spring 87 can provide stable elastic support for the push rod 86 on the inner side of the tube body 74. The push rod 86 is a stepped column structure, and the top end of the push rod 86 slides through the top surface of the limiting tube 72. The push rod 86 can move stably on the inner side of the limiting tube 72 and the tube body 74, and is limited by the end of the limiting tube 72 to avoid falling out of the shell assembly 7. The control assembly 9 includes an outer shell 91, and an electric push rod 92 and a control module 93 are installed inside the outer shell 91. The control module 93 is composed of a battery module, a single-chip microcomputer, a relay and a wireless module. The control module 93 is electrically connected to the electric push rod 92 and wirelessly connected to the mobile phone end. The operator can use the mobile phone end to send instructions to the control module 93, thereby realizing remote control of the electric push rod 92 and realizing power-off operation of the device.

[0030] The working principle of this technical solution is as follows: When the assembled access end 2 is connected to the circuit connection plug 3, the top of the claw 84 is hooked on the push rod 86, and the spring 87 is compressed to generate elastic energy storage. At this time, the control module 93 shrinks to the minimum stroke; when the operator remotely sends a signal from the mobile phone to control the disconnection of the assembled access end 2 and the circuit connection plug 3, the electric push rod 92 extends under the control of the control module 93, driving the limit block 81 to move upward. When the limit block 81 moves, it drives the bottom end of the claw 84 to move, thereby causing the claw 84 to rotate with the pin shaft 85 as the support. After the top of the claw 84 moves to both sides of the push rod 86, the push rod 86 loses the limit of the claw 84, and the spring 87 releases the elastic potential energy to drive the push rod 86 to move in the direction of the limit tube 72, thereby driving the circuit connection plug 3 to move upward to disengage from the assembled access end 2 to complete the power-off.
