A button is fixedly connected to the right side of the rectangular rod. A buckle is fixedly connected to the bottom of the slider. A limit ring is fixedly connected to the inner wall of the waterproof protective shell. The top of the protruding part of the buckle contacts the limit ring.

[0008] Furthermore, a sealing groove is provided on the sealing cover, and a wire is fixedly connected to the inner wall of the sealing groove.

[0009] Furthermore, an overcurrent protector is fixedly connected to the bottom of the first wire, and a second wire is fixedly connected to the bottom of the overcurrent protector. The bottom of the second wire extends to the outside of the waterproof protective shell, and the second wire is fixedly connected to the waterproof protective shell.

[0010] Furthermore, the anti-collision mechanism includes a fixing block 1 fixedly connected to the outer wall of the waterproof protective shell, and two fixing blocks 2 fixedly connected to the left side of the fixing block 1.

[0011] Furthermore, a sliding rod is fixedly connected between the two fixed blocks 2, and two sliders 2 are slidably connected to the outer wall of the sliding rod 1.

[0012] Furthermore, two springs are fitted on the outer wall of the waterproof protective shell. The sides of the two springs that are close to each other are fixedly connected to two sliders, and the sides of the two springs that are far apart from each other are fixedly connected to two fixing blocks. The sides of the two sliders that are close to each other are fixedly connected to springs.

[0013] Furthermore, a plurality of sliding rods are fixedly connected to the left side of the fixed block one, and baffles are slidably connected to the outer walls of the plurality of sliding rods two, and the right side of the baffles is fixedly connected to the spring sheet.

[0014] This utility model has the following beneficial effects:

[0015] 1. By setting up a quick-installation and quick-removal mechanism, when a fault occurs inside the protector or a periodic inspection is required, press the two buttons to bring them closer together. The two buttons drive the two springs to slide in the two mounting slots and move closer together. The two rectangular rods drive the two mounting slots to slide in the mounting slots and move closer together. At this time, the two springs and the telescopic rod are compressed by the slider. The two buckles also move closer together under the action of the two buckles until the two buckles leave the limit ring, and the sealing cover can be removed. After troubleshooting or completing the inspection, press the two rectangular rods to bring the two buckles closer together until the buckles can pass through the limit ring. Release the rectangular rods. The telescopic rod rebounds and drives the buckles to reset through the slider, so that the buckle protrusion is locked on the limit ring, allowing the sealing cover to be quickly installed on the waterproof protective shell. This makes it easy to remove the sealing cover of the waterproof protective shell when a fault occurs inside the protector or a periodic inspection is required, which not only improves the efficiency of maintenance work but also reduces the difficulty of maintenance.

[0016] 2. By setting up an anti-collision mechanism, when the device is impacted, the baffle is first impacted and slides to the right on the four sliding rods, causing the spring plate to stretch and push the two sliders away from each other. The two sliders move away from each other on the sliding rod, thus compressing the two springs. After the impact, the two springs rebound and reset, pushing the two sliders to reset. The two sliders then drive the spring plate to reset, and the spring plate drives the baffle to reset, preparing to buffer the next impact. This absorbs and disperses part of the impact force, so that when the device is impacted, the anti-collision mechanism will absorb and buffer part of the impact force, thereby avoiding the situation where the impact may cause the connection line to loosen, the solder joint to fall off, etc., which may affect the conductivity of the circuit.

[0030] A specific application of this embodiment is as follows: When in use, first place the device in the corresponding position. When the overcurrent protector malfunctions or requires periodic inspection, the overcurrent protector model is E71-20A. Its working principle is as follows: When the circuit current exceeds a preset threshold, the thermistor heats up and changes its physical properties, causing the conductive element to disconnect the circuit to cut off the overload current. Once the overload is eliminated, the thermistor cools down and returns to its original state. At the same time, the internal recovery mechanism (such as a spring) pushes the conductive element to reconnect the circuit, achieving automatic reset. Pressing the two buttons 216 brings them closer together. The two buttons 216 drive the two springs 315 to slide and move closer together in the two mounting slots 211 respectively. The two rectangular rods 215 drive the two mounting slots 211 to slide and move closer together in the mounting slots 211. At this time, the two springs 214 and the telescopic rod 212 are compressed by the slider 213. The two latches 217 also move closer together under the action of the two latches 217 until the two latches 217... Once the limiting ring 218 is removed, the sealing cover 111 can be removed. After troubleshooting or completing the inspection, press the two rectangular rods 215 to bring the two latches 217 closer together until the latches 217 can pass through the limiting ring 218. Release the rectangular rods 215. The telescopic rod 212 springs back and drives the latches 217 to reset via the slider 213, so that the protruding part of the latches 217 is locked on the limiting ring 218, allowing the sealing cover 111 to be quickly installed on the waterproof protective shell 1. When the device is impacted, the baffle 318 is the first to be impacted. Slide the four sliders 317 to the right, causing the spring plate 316 to stretch and push the two sliders 314 away from each other. The two sliders 314 move away from each other on the slider 313, thereby compressing the two springs 315. After the impact, the two springs 315 rebound and reset, pushing the two sliders 314 to reset. The two sliders 314 drive the spring plate 316 to reset, and the spring plate 316 drives the baffle 318 to reset, preparing to buffer the next impact, thereby absorbing and dispersing part of the impact force.
