[0020] Based on the above structural features, the shaft flip cover 4 presses the first convex hemisphere 401 into the semi-circular groove 303 through the sliding groove 304 of the micro motor box 3, thus completing the installation of the shaft flip cover 4; when the end cover 2 is assembled with the coil box 1, the induction coil and control element are placed in the coil box 1, and the wires are connected to the device in the micro motor box 3 through the first wire inlet hole 206 and the second wire inlet hole 305; a small motor is placed in the micro motor box 3, and the motor shaft passes through the shaft hole and protrudes into the motor shaft groove 302.

The sealing ring 202 squeezes the sealing ring in the sealing groove 106 to achieve the sealing between the inside of the coil box 1 and the outside.

[0021] Working principle.

[0022] The main body of coil box 1 is cylindrical, which facilitates the placement of the toroidal current transformer.

[0023] The end cover 2 is equipped with a micro motor box 3 for storing micro motors, which enables the fuse to trip even when the measurement and control device is very small.

[0024] Dedicated holes for installing ultrasonic sensors and infrared temperature sensors are provided on end cap 3, namely ultrasonic sensor hole 208 and infrared temperature measurement hole 209. This enriches the functions of the intelligent fuse's measurement and control sensors and improves the integration level.

[0025] The end cover 2 is provided with an indicator light hole 207 for mounting display LEDs, which provides a clear indication of the operating status.

[0026] A sealing groove 106 and a sealing ring 202 were added at the interface between the coil box 1 and the end cover 2 to improve the sealing performance.

[0027] A retaining ring 210 was added to the inside of the end cover 2, coil box 1, and interface to prevent the wires from pressing on the structural position of the end cover 2 and the housing during installation.

[0028] The design incorporates a hinged cover 4, which ensures an aesthetically pleasing appearance while also protecting the motor shaft and stainless steel pull wire.

This housing can be easily installed on the fuse tube of a drop-out fuse, and can meet the functions of measuring current, measuring temperature, and operating the motor to trip the fuse in a small size. Current and temperature measurement are respectively completed by the built-in induction coil and infrared temperature sensor; the fuse tripping function is achieved by the motor controlling the stainless steel wire to pull the fuse's pull pin, causing the pull pin to disengage, thereby actuating the spring mechanism to achieve the fuse tripping function.

[0030] The functions of the components related to this utility model are as follows: A fuse is an electrical device that breaks the circuit by melting a fusible element when the current exceeds a specified value, using the heat generated by the fuse itself.

[0031] Fusion tube: A heat-resistant and insulating tube used to protect the molten material.

[0032] Slide: A cut made to facilitate installation and fixation.

[0033] Ultrasonic sensor: It detects the presence or distance of an object by emitting ultrasonic waves and receiving the reflected waves.

[0034] Infrared temperature sensor: It measures the surface temperature of an object by receiving the infrared radiation emitted by the object.

[0035] Example 2, as a related component of this utility model, another possible implementation is as follows: The first convex hemisphere 401, the second convex hemisphere 402, and the semicircular groove 303 corresponding to the micro motor box 3 of the shaft flip cover 4 are changed to open holes. The opening and closing of the shaft flip cover 4 can also be achieved through shaft hole cooperation.

[0036] The protective part of the motor shaft, the shaft cover 4, can be a drawer-type shaft cover. Sliding rails are set on the micro motor box 3 and the drawer-type shaft cover respectively, and wire grooves are opened at the corresponding positions of the drawer-type shaft cover to achieve the same effect.

[0037] By opening screw holes in the fixing slot 103, the coil box 1 is fixed to the fuse tube of the fuse by tightening screws.

[0038] In the above embodiments, the descriptions of each embodiment have different focuses. For parts that are not described in detail or recorded in a certain embodiment, please refer to the relevant descriptions of other embodiments.
