Description

Technical Field

[0001] This invention relates to the field of electrical components, and in particular to a power-generating and temperature-measuring device that can be installed while energized. Background technology:

[0002] Most early distribution boxes and circuit breakers lacked the need for digital and IoT-based safety features during construction, and therefore did not sample data affecting safety, such as line temperature and voltage, during installation. This resulted in many accidents going unprepared. To address this need, the industry has added temperature monitoring and voltage sampling measures to these circuit breakers to prevent safety hazards. Some installations require disconnecting the power supply before installation, which is unsuitable for circuits that cannot be disconnected. Furthermore, the circuits of older equipment are often messy, leading to difficulties in disassembly and reassembly, and potentially causing other faults in downstream circuits after disassembly. Other installations do not require disconnecting the power supply, but these often only use magnets to attach the temperature measurement to the magnetic part of the conductor (without drawing power). This method has many hidden dangers. For example, because the magnets are exposed during installation, installers must be extremely careful to avoid electric shock. This installation method also has significant reliability risks, as it relies solely on magnet attachment without other reinforcement, making it highly susceptible to detachment during subsequent human operation. Interference from small creatures (such as rats and weasels) could also cause the probe to fall off. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a power-generating and temperature-measuring device that can be installed while energized.

[0004] To achieve the above objectives, the present invention employs the following technical solution:

[0005] A power-generating and temperature-measuring device that can be installed while energized includes an insulating outer casing. Inside the casing are a magnet and a magnet that is strongly attracted to a magnet bolt. The magnet has a ring structure. The top of the bolt has a recessed hexagonal socket. The end of the outer casing has a protruding head channel that communicates with the inner hole of the magnet and the hexagonal socket at the top of the bolt. A spring-shaped power-generating head is built into the head channel. A temperature sensor is placed inside the power-generating spring and extends out of the head channel.

[0006] Further technology of the present invention:

[0007] Preferably, the outer casing provides a first space for clamping with bolts, and the outer casing also provides a second space for clamping with magnets.

[0008] Preferably, the inner diameter of the first space is larger than the inner diameter of the second space.

[0009] Preferably, the inner diameter of the hexagonal socket at the top of the bolt is larger than the diameter of the inner hole of the magnet.

[0010] Preferably, the lower part of the spring-shaped power-taking head is provided with a drum-shaped protruding surface, which forms an interference fit with the inner hexagon of the bolt.

[0011] Preferably, the outer cover sidewall is provided with several grooves.

[0012] Compared with the prior art, the present invention has the following technical effects:

[0013] 1. The outer cover provides insulation and also secures the bolts to prevent them from coming loose;

[0014] 2. The magnet and bolt are strongly attracted to each other, strengthening the connection between the bolt and the device;

[0015] 3. The spring-shaped power-taking head, after the device is pressed into place, forms an interference fit with the inner hexagon of the bolt, realizing the power-taking function and enhancing the connection strength between the bolt and the device;

[0016] 4. The temperature sensor is placed inside the power-taking spring, which cleverly utilizes space to achieve miniaturization and reliability of the device. Attached Figure Description

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further explained below with reference to the specific accompanying drawings.

[0023] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0024] like Figure 1-3 The present invention provides a power-generating and temperature-measuring device that can be installed while energized;

[0025] Includes an insulating outer cover 1, the side wall of which is provided with several grooves 2 for easy handling;

[0026] The outer cover 1 has a first space 3 inside which is tightly fitted with the bolt 5. The bolt 5 is inserted into the first space 3 to prevent it from falling out.

[0027] The outer casing 1 also provides a second space 4 that is tightly fitted with the magnet 6. The magnet 6 is placed in the second space 4 and is strongly attracted to the magnet 6 in the second space 4, which strengthens the connection strength between the bolt 5 and the device.

[0028] The inner diameter of the first space 3 is larger than the inner diameter of the second space 4 to prevent the bolt 5 from being inserted into the second space 4 and affecting the placement of the magnet 6.

[0029] The magnet 6 has a ring structure, the bolt 5 has a recessed internal hexagon 8 at the top, and the outer cover 1 has a protruding head channel 7 at the end.

[0030] The head channel 7 is connected to the inner hole 9 of the magnet 6 and the internal hexagon 8 at the top of the bolt 5, and has a built-in spring-shaped power-taking head 10. The inner diameter of the internal hexagon 8 at the top of the bolt 5 is larger than the diameter of the inner hole 9 of the magnet 6. The lower part of the spring-shaped power-taking head 10 is provided with a drum-shaped protruding surface 11. The drum-shaped protruding surface 11 forms an interference fit with the internal hexagon 8 of the bolt 5, realizing the power-taking function and enhancing the connection strength between the bolt 5 and the device.

[0031] The temperature sensor is placed inside the power-taking spring and extends into the head channel 7, which cleverly utilizes space to achieve miniaturization and reliability of the device.

[0032] Working principle:

[0033] Power supply: The drum-shaped power spring draws power through interference contact with the inner hole of the bolt.

[0034] Temperature measurement: The temperature probe obtains circuit temperature parameters by contacting the drum-shaped spring contact and the inner wall of the screw hole. Alternatively, thermally conductive adhesive can be applied to the space where the temperature probe is located to transmit temperature information.

[0035] The foregoing has shown and described the basic principles, main features, and characteristics of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
