[0039] The working principle of the utility model is as follows: by setting the card installation mechanism 22, during the use of the device, the limit card 224 can be adjusted to resist the limit spring 223 to shrink, so that the block 225 on the limit card 224 can be moved inwards. When the block 225 is moved inwards, the top cover 21 can be covered on the top of the box body 3. When the block 225 contacts the slot 222, it is reset by the limit spring 223. At this time, the limit spring 223 resists the block 225 on the limit card 224 and is inserted into the slot 222. At this time, the block 225 and the slot 222 can be mutually limited to assist in the limited installation of the top cover 21 on the box body 3, so that the device as a whole does not need to use screws to install the top cover 21 during the installation process, and the overall installation of the NTC module mechanism 5 is more convenient.
[0040] By setting the clamping mechanism 22, when the device needs to be disassembled during use, the limit plate can be pressed downward, and the guide groove 2210 on the limit plate abuts against the inclined surface of the guide block 226. The inclined surface of the guide block 226 is limited, and the guide block 226 can be urged to slide inward. During this period, the limit clamp 224 abuts against the limit spring 223 to shrink, and the clamping block 225 leaves the clamping groove 222. At this time, the top cover 21 on the box body 3 can be quickly removed, so that the device as a whole is convenient for quick maintenance and disassembly of the top cover 21. At the same time, after the top cover 21 is installed, the limit spring 223 at the bottom of the top plate 231 abuts against the pressure plate 233 to contact the NTC module mechanism 5 The main body makes the NTC module mechanism 5 body stably installed inside the box body 3. When the top of the top cover 21 is opened, the NTC module mechanism 5 can be directly removed, making the overall disassembly and assembly of the device more convenient. The design that is easy to disassemble and assemble can be quickly operated when maintenance or replacement is required, saving time and labor costs. At the same time, it can be replaced or upgraded as needed, improving the flexibility and scalability of the system. The easy disassembly and assembly feature can help engineers complete debugging work faster, and operators can handle modules more carefully to reduce the risk of accidental damage. The overall structural design is compact and does not take up too much space, which is beneficial to the overall layout of the system and space utilization.
[0041] By providing the circuit breaker protection device 6, during the use of the device, the fuse 64 can be installed between the inner sides of the conductive sleeve frame 63. At this time, the conductive spring 62 is reset to resist the conductive sleeve frame 63, so that the fuse 64 can be assisted to be fixed at the electrode sheet 52. If a short circuit occurs during use, the fuse 64 will be blown first, thereby having a good protective effect on the NTC module mechanism 5, and can avoid the electrode sheet 52 and the NTC module body 53 from being blown and damaged. When the fuse 64 needs to be replaced after it is blown, the adjustment plate 65 can be pressed to push the two sets of conductive sleeve frames 63 apart to remove the melted fuse 64. At this time, the new fuse 64 can be placed inside the conductive sleeve frame 63 to complete the replacement, so that the overall device is easy to quickly disassemble, maintain and repair, and has strong protection performance to avoid the problem of damage to the NTC module mechanism 5.
