Terminals 50 are provided at both sides of the upper end of the voltage sensor body 10, and the terminals 50 are used to interface the voltage sensor body 10 with the connection wires 200 of the related devices. The fixing bolts 40 are provided at both sides of the lower end of the voltage sensor body 10, and the fixing bolts 40 are used to fixedly connect the voltage sensor body 10 with the device mounting plate body 300. The closing cap 20 is connected to the outside of the voltage sensor body 10 by a built-in lock mechanism 30, the closing cap 20 is used to close and cover the voltage sensor body 10, and a connection wire 200 connected to the voltage sensor body 10 passes through the closing cap 20.
The built-in lock mechanism 30 includes: the device comprises a convex column 31, a clamping groove 32, a U-shaped connecting frame 33, a sliding clamping block 34 and a first connecting spring 35. The boss 31 is vertically fixedly coupled to the upper end of the fixing bolt 40. The clamping groove 32 is formed at the side wall of the lower end of the convex column 31. The U-shaped connection frame 33 is horizontally fixedly connected to the inner wall of the lower end of the closing cap 20. The sliding clamping block 34 is horizontally and slidably inserted into the tail end of the U-shaped connecting frame 33, and the lower side wall of the end of the sliding clamping block 34, which is close to the center of the closing cover 20, is a smooth arc surface. The first connecting spring 35 is sleeved at the end of the sliding clamping block 34 close to the inner wall of the closing cover 20, and the first connecting spring 35 is connected between the sliding clamping block 34 and the U-shaped connecting frame 33.
When the closing cap 20 is covered to the position where the voltage sensor body 10 is mounted, the slide latch 34 exists in up-down alignment with the boss 31. When the closing cap 20 is pressed down from the top, the sliding clamping block 34 is pressed to the upper end of the protruding column 31 by means of the smooth arc surface. The sliding block 34 is transversely moved when being pressed due to the smooth arc surface, and the first connecting spring 35 is stretched to generate resilience force in the process. And the end of the sliding latch 34 after the traverse slides down along the sidewall of the boss 31. After the end of the sliding clamping block 34 is aligned with the position of the clamping groove 32, the sliding clamping block 34 is inserted into the clamping groove 32 under the resilience force of the first connecting spring 35, so that the closing cap 20 is fixedly installed at the position of the voltage sensor main body 10. Since the built-in lock mechanism 30 is located inside the closing cap 20, it is impossible to open from the outside, and it is ensured that the line of the voltage sensor main body 10 before acceptance is tampered with.
The tamper-resistant function-based voltage sensor 100 further includes: a wire body fixing mechanism 60. The wire body fixing mechanism 60 includes: the first bar-shaped chute 61, the second bar-shaped chute 62, the sliding cross column 63, the limiting clamp plate 64, the second connecting spring 65, the supporting frame 66, the linkage rotating rod 67 and the ejection mechanism 68. The first bar-shaped chute 61 is horizontally opened at the inner top of the closing cap 20. The limiting clamp plate 64 is vertically and slidably connected to the first bar-shaped sliding groove 61. The second bar-shaped chute 62 is vertically opened at the front and rear inner walls of the closing cap 20. The sliding cross post 63 is horizontally slidably connected to the second bar chute 62. The second connecting spring 65 is connected between the inner wall of the first bar-shaped chute 61 and the limit plate 64. The support bracket 66 is fixedly connected to the outer wall of the voltage sensor body 10. The linkage rotating rod 67 is rotatably connected to the end of the supporting frame 66 through a rotating shaft, and the upper end of the linkage rotating rod 67 is attached to the outer wall of the limit clamping plate 64. The ejector mechanism 68 is provided on the lower side of the link lever 67.
The ejector mechanism 68 includes: a threaded connection block 681, a threaded mandril 682, a swivel 683, a linkage block 684, a first telescoping connection rod 685, and a third connection spring 686.

The threaded plunger 682 is threaded vertically through the threaded connection block 681, and the threaded plunger 682 is in up-down alignment with the sliding cross-post 63. The linkage block 684 is connected to the underside of the support frame 66 by a first telescoping connection rod 685. The swivel handle 683 is fixedly connected to the lower end of the threaded push rod 682, and the end of the linkage block 684 is located on the upper side of the swivel handle 683, while the lower end of the linkage rod 67 is obliquely abutted against the upper side of the linkage block 684. The third connecting spring 686 is sleeved on the first telescopic connecting rod 685, and two ends of the third connecting spring 686 are fixedly connected to the fixed end and the telescopic end of the first telescopic connecting rod 685 respectively.
When the connection lead 200 passes through the corresponding position of the closing cap 10 such that the connection lead 200 is laterally erected on the sliding lateral column 63 and the connection lead 200 is connected with the terminal 50 of the voltage sensor main body 10, the threaded push rod 682 is rotated by the rotating handle 683 such that the threaded push rod 682 pushes the sliding lateral column 63 upward, and the sliding lateral column 63 slides upward along the second bar chute 62. The sliding cross post 63 presses the connecting wire 200 between the stop plate 64 and the side wall of the closure cap 20. And after the stem 683 is moved up to the corresponding position, the stem 683 pushes against the linkage block 684. The linkage block 684 presses the lower end of the linkage rotating rod 67 by lifting the first telescopic connecting rod 685, and the upper end of the linkage rotating rod 67 pushes the limiting clamp plate 64 to enable the linkage rotating rod to slide along the first bar-shaped sliding groove 61 to press the connecting lead 200 on the sliding cross column 63. This allows the portion of the connecting wire 200 near the terminal 50 to be clamped and prevents the outer portion of the connecting wire 200 from being pulled to affect the connection position of the terminal 50.

The mounting box 71 is fixedly attached to the top outside of the closure 20. A pair of small electric telescopic rods 72 are vertically fixedly connected to the inner sides of the mounting boxes 71 in left and right pairs. The top cover 73 is horizontally fixedly connected to the upper end of the small-sized electric telescopic rod 72, and the top cover 73 is closed and fitted on the upper side of the mounting box 71. A GPS locator 74 is fixedly mounted to the underside of the top cover 73. A power supply 75 is mounted to the inside of the small electric telescopic rod 72, and the power supply 75 supplies power to the small electric telescopic rod 72 and the GPS locator 74. The signal lamp 77 is provided with a plurality of monitoring terminals 76 distributed in the background. Each GPS locator 74 is provided with an independent number and each signal light 77 is provided with a corresponding number. The GPS locator 74 of the same independent number is wirelessly connected with the signal lamp 77 through the rear set of monitoring terminals 76. A trigger mechanism 78 is provided on the outer wall of the closure cap 20, the trigger mechanism 78 being used to trigger the GPS locator 74.

A supporting ceramic body 785 is connected between the baffle 781 and the closure cap 20.
When an outside person hits the closing cap 20 in an attempt to break the closing cap 20, the supporting ceramic body 785 between the baffle 781 and the closing cap 20 breaks upon the impact of the baffle 781. The baffle 781 then slides against the closing cover 20 by means of the second telescopic connecting rod 782 under the resilient force of the fourth connecting spring 783, so that the pressure-sensitive switch 784 senses. The pressure sensitive switch 784 activates the GPS locator 74. The GPS locator 74 transmits a position signal and the background monitor terminal 76 receives the signal and then causes the signal light 77, which is the same number as the GPS locator 74, to be activated. The background personnel can check the corresponding position by means of the lighted signal lamp 77.
The trigger mechanism 78 further includes: a resilient rubber striker 786 for protecting pressure sensitive switch 784. The resilient rubber striker 786 is fixedly attached to the flapper 781 and the resilient rubber striker 786 is present in alignment with the pressure sensitive switch 784. The resilient rubber striker 786 prevents the flapper 781 from directly striking the pressure sensitive switch 784 and causing damage.
